WILLIAM HAMANN, 0F IRONDEQUOI'I, NEW YORK, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO UNITED SHOE MACHINERY COIELPORALION,v OF PATERSON, NEW J ER- SEY, A, CORPORATION OF NEW JERSEY.

MACHINE FOR MARKING SI-IOE-'U'PEERS To all whom 1f/may concern.'

Be it knownthat I, WILLIAM HAMANN, a citizen of the United States, residing at Irondequoit, in the county of Monroe and State of New York, have invented certain Improvements in c Machines for Marking Shoe-Uppers, of whichk the following de- .scription, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several gures.

IThis invention relates to machines for marking shoe uppers, the embodiment of the machine representedV herein being especially designed to indicate on the stock the locations ovf buttons or buttonholes, and more particularly the location of buttonholes on the bottonhole flies of shoe uppers.

The marking machine of this invention is of the gang type and is arranged to mark substantially simultaneously the 'locations of a desired number of buttonholes on shoe flies. One disadvantage of gang machines of this type has been the diflic-ulty eX- perienced in adjusting the series of markers to variance in spacing and in curvature to conform with the curvature of the fly edge, so that the line of location marks will be substantially parallel with the fly edge and the marks will be uniformly spaced from each other.

It is well known that the curvature of fly edges not only varies slightly from size to size of the same pattern of fly, but that there is radical variance in the curvatures of liy edges of dierent patterns andV styles of lbutton shoes. A gang type of marking machine, to be of practical value, must be constructed to provide for wide variance in the linear arrangement of its markers. In prior ,Patent'No 1,191,965, dated July 25, 1916 issued on my application filed October 25, 1913, under Serial No. 797,241, I'have disclosed a gang' type of buttonhole marking machine providing for adjustment of its markers within a relatively wide range of curvilinear arrangementV and relative spacing, and have provided means for automatically grading the curve of a selected pattern from size to size of the flies fof that pattern, this grading of the curvature being accomplished coincidently with the change in relative Vspacing of the markers which accom- Specification of Letters Patent.

pplicaton filed April 8, 1916. Serial No. 89,968.

panies the change fromsize to size of flies of the same pattern. In addition, means are provided for varying the pattern curve y within a relatively wide range of patterns without alfecting the automatic curve gradation from size to size.V

An objec-t of the present invention is to provide an improved marking machine of the general type disclosed in said Letters Patent to the end that, without sacrificing any of the many advantages characteristic of the machine disclosed in said Letters Patent `and responsible for its successful j `spacing is effected by power-operated mechanism which, as shown, is manually controlled. Y In accordance with another feature of the invention the mechanism for relatively adjusting the marker elements to vary their spacing is constructed and arranged to be actuated to vary the spacing of the marker elements by determinate step-bystep movements of a marker element spacing member. Advantageously, and as illustrated, the power operating means may be in the form of a mechanical motor arranged to move the spacing member in one element-V spacing direction. The spacing member may be moved in the reverse spacing direction through manually operable` means and as illustrated, reverse movement of the spacing member is arranged to restore power potential of the motor. ,f

In the machine as previously constructed and as illustrated herein, a series of marker elements are mounted for sliding movement and are providedwith projections entering an elongated curved slot in a guiding member arranged for adjustment relatively to the marker elements.` The slot in the yguiding member determines the linear arrangement of the marker elements and adjusting movement of the guiding member varies the linear arrangement of the marker elements. A further feature of the invention -consists in a novel arrangement and construction of guiding 'means by which the position of a vguide slot relatively to its guiding member 'retained in guide supportingl position. In

the particular construction illustrated, the support is arrangedalso to hold a central marker' elementyagainst movement relatively to the other elements and is also arranged determinately to position and pivotally to support the guiding member.

i These Yand other features, including a novel construction of detachable spacer v plate and support, will be more fully aplected for illustration, 1

parent from the following detailed description read in'connection with the accompanying drawings. a

Figs. y9 and 10 are perspective views of i theV end gages carried bythe series of marker r elements to coperatev with the ends of the buttonhole flies and Fig. 11,'showsin section and 'on anl enciprocating movement toward and from the bed. A driven shaft 8 extends lengthwise of the machine bed in the line of standards i and is provided with eccentrics 1Q whose straps 12 are operatively connected to the head 6 at points adjacent'to the standards.

At one end of the bed a pulley 14 is mounted upon a short shaft 16 parallel with the extended end of shaft 8, the pulley beingcontinuously driven by suitable power, such 'as the belt and motor shown. The

`shaft 16 carries a gear 17 meshing with a driving gear 18 loosely mounted on shaft 8 Vand having one face formed as a clutch face.

The shaft 8 carries adjacent to the vdriven gear 18 a hub 2O keyed to the shaft and having a clutch yface 2l arranged to engage the corresponding clutch face ontlie gear 18. The hub has a portion ofiits bore en-. larged to receive and house a coiled spring 22, (Fig. 8), sleeved on shaft 8V with one end abutting gear 18, the other end acting against the h ub and normally tending to move the hub out of clutching engagement with the gear 18. A plurality ofv coiled springs 19 interposed between theopposite A face Vof gear 18 and a suitable abutment (F ig. 8) hold the gear against movement on shaft 8 sol that it forms atensioning abutment for spring 22. "Opposed rollers 24 extend from the side of the machine bed in linegwithrthe hub and are arranged to seat in opposed radially offset depressions in the face of the hub to permit the spring V22 to move thehub to unclutcliing position relatively to the gear 18. These rollers,

'vwhen the hubV has kbeen moved .to engage` vto which it is keyed, the rollers 24 entering `into their respectivedepressions inthe face of the hub 20 and the spring 22 simulta-V neously throwingfthe hub out of vclutching engagement with the-gear. The" rotation of the driven shaft 8 willreciprocate the operating head 6 through the'eceentrics 10 and their straps 12 'which are connected Vwith the head.` Reciprocation of the head operates a plurality of'marker elements, as hereinafter described. f

In order to move the hub into'- clutching engagement with the gearl18 so as to ro-Y- tate thehub depressions beyond the rollers `2-1 aclutch operating arm I26 iscarr'ied by a sleeve' 27 loose'ron the shaft 8 and is provided witha beveledplate forminga cam finger 28 held in a plane to engage a pin 30 on the hub when the arm is moved to .engage the cam with the pin. A spring 32.

' a treadle (not shown) will partially rotate sleeve 27 to move the arm 26 with its cam 28 in a direction to'engage the pin 30 and move lthe hub into clutching engagement with the gear 18. The treadle may then be released as the initial rotating movement given the hub when first clutched to the gear, -will clear the depressions from the rollers 24 and cause the rollers to hold the hub land gear in clutching engagement for one revolution of the hub and its shaft.

The downward movement of the operating head 6 is designed to engage the upper arms of a series of marker elements to kmove said arms relatively to the lower arms of said series to mark stock supported between the upper and lower arms of said series of marker elements. These marker elements form in effect marking units, each marker element comprising connected relatively movable upper andlower marking arms, and the series of marker elements being mounted on the bed 2 for horizontal swinging movementto vary their relative spacing and for sliding movement relatively to their pivots to vary their linear arrangement. rihe present invention is not concerned with the specific construction of the marker elements, except as to the general type ofmarker element. One form of marker element which may be employed, and which is illustrated herein comprising opposed electrically heated cauterizing markers arranged for relative movement to engage and sear or cauterize the surface of the stock interposed y 'between them. The construction and V.electric heat control for these markers forms the subject-matter of United States Letters Patent No. 1,278,842 granted September 17, 1918 upon application of Arthur W. Brice and Irving E. Booth.

The machine bed is provided withispaced raised bearing por ' ions 38 and 40. The rear bearing portion 36 1s of curved outline'and hasupstanding therefrom a plurality of uniformly spaced studs 42 having flanged heads 44. These studs are engaged by the channeled base plates 46 (Figs.` 5 and v7) of a series of marker elements comprising upper marking arms 52 and lower marking arms 48 .mounted at their rear ends in frames which include the base plates 46, and at their forward ends, mounted in and carried 'by base plates 50 supported and guided upon the raised portions 40 of the bed. The rear ends of the upper marking armsL 52 of each marker element are carried in brackets 54 and are pivotally connected with the frames at the rear ends' of: the lower armsr` A coiled spring 56 interposed between the rear ends v ofthe upper and lower marking arms tends to spread these arms apart at their forward or marking ends, while stop members 58, 60 carried by the arms intermediate of their ends limit their movement toward each other.` The. ends of the marking arms carry markers in the form of loops ofresistance wire 62 detachably secured to the ends of the arms and connected in series electrically' with each other and with suitable current controlling devices. The specific construction and electrical equipment of the illustrated marker elements is described in detail and forms part of the invention disclosed in the patent aforesaid, and need not be considered in detail herein. It is illustrated suiiiciently for 'the purposes of the present Vapplication by Figs. 10,and 11 of the drawings.

lEhe forward ends of the base plates 50 detachably carry posts 64 upon which are pivotally mounted adjacent to their forward ends work supporting tables 66 having openings therein in line with the lower markers 62 and having their rear ends coperating with the upper arms of the marker elements. Each base plate 50 is formed with an' upstanding rib 68 (Figs. 7 and 11) and the upper marking arm 152 carries spaced depending legs 70 embracing opposite sides of the rib. lThe rear ends of the tables 66ers bifurcated to embrace'the ribs 68 and to seat loosely in bifurcations at the lower ends of the legs 70. The coiled springs 56 tend, through this connection, to move the'rear bifurcatedrends of the tables 66 upwardly to engage normally with pins 72l extending from the ribs 68.

In this position the tables are located above the lower markers 62 and prevent Vcontact of the stock supported by the tables with the markers. rlhe ri'bs 68 also carry 'wire guards 74 extending forwardly inline with the ends of the markinfr upper arms 52 and below their markers 62, so that when a button-hole fly is placed upon the'series of tables v66, it' will be protected from engagement with the cauterizing wires forming the Vmarkers 62 by the-tables 66 and by the wirey guards 74.

In line with the stops 58, 60, theupper arms 52 carry cushioned abutment studs 76 arranged to be engaged by the operating head 6 when 1t 1s moved downwardly by rotation of the shaft 8. This action causes the Vwill be marked at oppositel faces by the cauterizing :markers 62 which are heated to' cauterizing temperature through certain electric connections and controlling devices that need not be described. Y .e

The channeled base plates 46,V of `the marker elements are of suliicientlength to permit a relatively'wide range ofmovement of the marking arms in the direction of their length and relatively to the studs 42. These plates also `swivel the marker elements on the flanged heads of the studs so that all of the series of marker elements 'except a centrallyv located element may beswung to varyl the spacing between adjacent arms and at the same time may be moved in the direction of their length independently to vary their curvilinear arrangement so as to conform to various curvatures of flies operated upon.

Y This central element, best seen in Figs.11, 2, 3 and 5, is held against bodily and swinging movement by means later to be described..

The forward portion ofthe machine bed is cut away to provide space for theguiding and adjusting mechanism of the marker ele- ,ments This adjustment of the marker. elements is made relatively to vthe Vcentral `marker element, previously referred t'o. rlhe base'plates-O for the lower. arms 48 of the marker elements carry at their forward ends depending guide pins 78 (Figs. 7 and l1) which, except in the case of the .central fixed marker element, extend in'and through guiding slots 132 in complemental pivotally interconnected guiding plates or. templets 128 and v are of sufficient length to extend through these guiding slots and into slots 162 in a reciprocating spacer plate 1.50 beneath the templet :plates which moves theV series of f marker elements toward and from thefixed central marker elementl andY by reason of certain connections with the piivoted guid-V v ing plates 100, 102, also may operate these r.templets pivotalljT mounted upon thepin 7 8 'j of' the` fixed central marker element. This Y` plates to grade the linear of curvilinear arrangement of the markers coincidently with the change in relative spacing kof the marky ers, as in my prior patent previously re-` ferred to.

My improved construction.includes mechTH anismarranged to engage pin 78 of the central marker element to maintain the central v marker element fixed andY to support the adjacent inner ends of the guiding plates or mechanism isV designed to facilitate thejassembling of the parts as well as ytheir-removal. Y Y Conveniently the Vbed vof the machine at its forwardV edge may be provided with a Y bracket 80V (Figs. 4 and 5) extending forwardly toward the frontof the machine and including a socket 82 receivingand guiding for vertical movement a post 84 having a` rackr86 formed on one face thereof. The bracket adjacent to this `socket is counter.-

Vbored (Figs. 4 and 5) to receive a spindle 88 said pin 78.

' from each other.

having a lpinion90-at onere-nd thereof 'ai'-V ranged to mesh with the rack 86, solth'atby `ceive and support theends of the guiding yturning the spindle thepost maybe moved up to receive'and support the pin 7 8 of the central markerelement, as well as tojre-v platesor teinplets'100, 102 which pivot on 'i The upperend ofthe post 84 is apertured as at 9.2 to receive lthe-pin 78 of the central marker element, and is cut away at :opposite sides to form acentr'al web 94 (Fig.v 4) through which the aperture or socket 92 extends.V yThe central webf94 will enter into thecentral straight slot'ofthe spacing'plate 150 which cooperates Iwith the pinsV 78. ofthe movable marker Velements and with' their swinging guide plates. In order'to lock the post in its raised supporting position, thev spindle 88 is formed with'a flat portion 96 (Fig. 4)y and a spring pressed vblock `98 mounted in a socket in the bracket-*normally engages the periphery of the spindle as it is turned, the flattened portion 96 of the spindley engaging the block when the post hasV reached its raised position andthe pressureV of vthe spring against the block holding the post in its raised position until the spindle is forcibly turned in the, oppositev direction to lower the post. Complemental guideY Yplates 100, 102, seenV best in Fig. '3, are ipiv` otally interconnectedat theirV inner ends by the pin 78 vof the centra-l stationary marker arm, these ends `of the plates being mounted upon this pin and supported bylthe upper surface -of the web 94 '(see Fig.v 5). f The outer or free ends of the plates carry. pivotedv blocks 122 Vwhich seat between in-V clined guiding walls 120 formed on 'pivot-lV ed adjusting levers at opposite sides of the machine bed,.these levers'themselves being carried .upon sliding beds V104, 106,

Pivotally` mounted upon the levers 108 which7 forconvenience, will be hereinafter designated asl the lower levers, at corresponding points between their pivots and their free ends are upper adjusting levers 114 having arcuate slots therein to permit the latches of the lower levers to extend therethrough and move relatively thereto, and having spring v pressed latches 116 at their free ends cooperating with an arcuate series ot' latching pins 118 on the outer ends of the lower levers 108 to Vhold `the upper levers in adjusted kposition relative to the lower levers.`

The upper leversl are provided with rear wardly inclined upstanding guide walls 120 and the outer or free ends of the guiding plates 100, 102, carry pivoted blocks 122 (Figs. 3 and 6) guided between these inclined walls. By swinging the lower levers 108 the upper levers 114 will also be swung to swing in turn the guiding plates 100, 102 on their pivots to vary the line of their slots and the guiding line for the marker elements. As the adjusting means at the opposite sides of the bed are independent, it is obvious that the adjustments may be independent. The upper levers 114 may also be adjusted relatively to the lower levers and independently thereof to provide further variance of the line of the guiding` slots.

These described. adjustment features are similar Generally to those employed in U. S. Letters Jatent No. 1,191,965 hereinbetore referred to. I have, however, provided a wider range of adjustment through additional adjustment means in the construction ofthe guiding plates 100, 102 as best seen in Fig. 3. Each guiding plate includes a main or base plate 1-24 and a supplemental guiding plate 128. rThe inner adjacent ends of the base plates 124 are pivotally mounted on the pin 78 of the central marker'element andl are reduced in thickness t0 permitV these plates to be overlapped at their point of pivotal connection. carry blocks 122 at the under side of their outer ends, and intermediate of their ends are formed with curved guide slots 126 therein, these slots being enlarged in width from a'point adjacent their inner ends to the outer ends of the slots where the width reaches its maximum. The upper faces of these main or base plates 124 between the ends of the plates are reduced in thickness to receive the supplemental upper guide plates 128 pivoted to the base Vplates 124 at their inner ends, as at 130, and having guide slots 132 formed therein of a width which is sufficient to receive and guide the pins 78 of the marker elements. These slots at their outer ends are enlarged in width to the maximum width of the slots in the base plates 124 and form with the base plates housings to receive the pins 78 of surplus end markers of the series of marker elements (see Fig. The outer ends of these upperV plates`128 The base platesf124- carry studs 13,7 (Fig. 3) which may be clamped in a series of notches 136 formedv in the base plates 124Y by means of a clamping nut 138. Preferably, a pointer 140 is carried by the stur and coperates with in-.

dication marks formed on the faces of the `outer ends of the base plates 124, such as the numerals 5, 4, etc., shown in Fig. 3, to indicate certain curve adjustments Vof the'slots in the upper plate. Obviously, as the curved slot in the base plate 124 is of substantial width, the provision of a supplemental upper plate 128 having a curved slot alined with the slot in the base plate 124 and of narrower `width to receive and guide the pins 78 of the marker elements, provides the guiding plates 100, 102 with a relatively wide range of curve adjustment, per se, and with a wider range of curve adjustment than the single guiding plates of my prior patent aforesaid.

Aside `from the curve adjustment of the guiding plates V100, 102 obtained through manually swinging the adjusting levers 108, 114, -to establish a desired pattern or style curve, means are provided for automatically swinging said guiding plates to eect an automatic gradingv of the selected pattern curve 1n changing the spacing of the marker elements fromsize to size of the pattern. j

The machine bed is provided with opposed supporting plates 142 extending from the front edge thereof'rearwardly (Figs. 3Y

and 6) and a spacer frame 144 is mounted within the bed and supported by these plates for movement transversely ofthe bed. This frame is formed with a central raised portion 146, upon the inner edge of which-are dowel pins 148 which enter into corresponding'apertures in a spacer plate 150 supported upon and extending inwardly from the .inner edge of the spacer frame. rThis plate isdetachably clamped to the frame by means of `headed pins 152 Whose heads seat in channeled slots in the rear edge of the spacer plate (see Figs. 3 and 6).y

The lower ends of the pins 1.52 extend through the frame and carry washers 154 (Fig. 6). Coiled springs 156 (Fig. 6) seated on the pins 152 between the frame and the washers 154 act against these washers and normally tend to hold the pin heads in Vlocking position relatively to the Vspacer along a curved line'v whichrisfnot the arc of a determinate circle,'the. slots will be divergent along non-radial lines, although in some Ainstances the arrangement may be substantially radial." Obviously, as ythe plate is detachable, differently slotted plates may be supplied for diii'erent ranges of curve ad-V justment. The central slot is vstraif z,'ht and will extend in the lineof movement of the 'spacerV plate and will Vembrace and be guided on'the web 94'v of the supporting post for the Vcentral marker element and for the guiding plates, soithat the central marker element` is not moved laterallyby movement of the marker. element,.adjustment of thesevplatesA Y 'l selected pattern.

The pins 780i' the marker elements except the central marker element will extend through the slots in the guides 100, 102 a sufficient distance to enter into Athe divergentslots 162 sov that these marker elements of therespective 'pins will be Yrelatively moved las ythe spacerplate 150 is moved toward and Jfrom the series oiimarker elements; Since the vguiding plates 100, 102H arepii'fotedy onvthe pin v78 of the centralk will not affect said central element.

A rlflie base of the spacer frame 144 at the Y edges adjacent the guides Y142 of the bed is` formed with guide channels .164 (Fig. having outwardly converging portions 166 (Fig.v 3) adjacent the :trent end ot the frame. rllie carrier plates 104,106at the opposite sides of the bed carry depending rollers 170 (Fig. 6) which enter Vinto the straight portions ot the guide Vchannels 164 at the*- rear of the spacer frame when the frame is first linserted into the bed and movedfalong the guide plates 14,2. When the Vframe has be'enpo'sition'ed to enter the vpins 78 of the marker elements into the open Yends of the spacer plate slots 162, the rollers 170 will have reached the convergingiportions 166 of thesel guide, channels.V This position will locate tlie'marlrers 162 in theirpo'sitions of greatest relative spacing. lt will also locate 50 the , guidingl plates 100, 102 withl the slots forming the longest and iattest curve-for the .Asthespacer "framefaiid plate is moved inwardly from this point, the sides of Athe diverging slots 162 acting against the pins 78 will cause .the marker elements ,to be moved closerV together and relatively to the tixedcentral marker with which the straight central slot zot the spacer coperates. reason of ksuch movement of the trame and spacer plate', the' carrier platesf104, 106 will b'e moved inwardly toward the center of the spacer plate'by reason of the cam action of y the sides of theconverging slots 166 uponthe'rollers 1700i these carrier plates. Such f the slot in the guiding plates 100, 102 will be A 175 a movement of 'the carrier plates will move the ends of lboth guiding plates 100, 102out- I wardly or toward the operator, by reasonof" the thrust against the pivoted blocks ,122," by the converging guide walls 120 of the up,-V per adj usting'levers, as the carrier plates are 'moved toward the' center ot" the machine inwardly. Consequently, the curvature of reduced as the spacingV of the markers is increased onincreasinglysmaller sizes of buttonhole flies. Y A f Upon movement *ofV the-'spacer frame and plate in the opposite direction or toward the operator for` increase'in sizes of the ies, thef reverse action takes place, the spacing of the :markers being increased andthe curvature afforded bythe `slots in the guidingl plates being relatively decreased.. It should be stated that in referring to spacing for larger and smaller rvsizes, it is understood that reference is made' to larger and Ysmaller sizes Y of shoe flies employing the same number of buttonholes, so that for a larger size of iiy an increased spacing of the buttons isnecessary, and vice versa. The described construction, therefore, provides means for .automatically grading the line of curve ofi-the markers'to correspond with the changefrom t one size to another of the flies being marked and' thisautomatic 'gradation is effected through the coperation of the spacing mechanism which changes the relative spacing of the markers for the di'erentsizes of flies'- Y with the guiding plates which initially determine the curvilinear arrangement of the marker elements. v Y

corresponding `guiding hole VfliesA relatively .to the markersso that the buttonholelocations will be uniformly that the endV buttonholes will be at predeter! spaced from the outer edge-ofthe fly and s0 Y' i Y Y l In order properly to positionthebutton- .mined'distances from the ends of the fly,

' opposite ends of the fly, these gaging means beingarranged to retain the same positional relation to the stock in all adjusted positions of the markers.

Accordingly, a plurality of back or fly edge gages 172 (see Fig. 11), preferably three in number, are carried by the stock supporting tables 616 of certain of the markers'including the fixed central marker and marking elements at opposite sides of the central marker. These gages are in the form preferably of L-shaped plates, one arm of which is slotted and is adj ustably secured to the stock supporting table 66, the other arm of the plate forming a vertical abutment against which the edge of the stock,- in the present instance, the curved edge of the buttonhole fly,-will rest when the fly is properly positioned on the table. As these gages are carried by the tables of the several marking elements and move with the elements in all adjustments thereof, they will necessarily Amaintain the'same positional relation to the elements and'to the work in all positions of adjustment of the marker elements.

rllhe number of marker elements on a machine will correspond. with they greatesty number of buttonhole locations that may be desired upon buttonhole flies. When a less number is desired to be used, the surplus marker elements at the ends of the series will be displaced from the work marking area by retracting the spacer frame with its plate 150 until the pins 7 8 of these markers arev freed, and then moving pins 7 8 of the surplus marker elements into the outer enlarged ends of the slots of the guiding plates 100, 102 the pins of such displaced marker elements being shown in section in Fig. 8. The spacer frame and its plate are then moved back to engage .the pins of the active marker elements. If the pins 78 `of those marker elements which must be displacedv from the work marking area eannot allbe entered into the enlarged ends of the slots, the pins of the surplus marker i elements may be positioned at the extreme ing plates without interfering with the opass ends of the slots in the guiding plates out of the work marking area and will simply be moved rearwardly or forwardly upon similar movements of the spacer and guideration of the machine.

Under such conditions of operation it will be obvious that end gages for the stock, if carried by the marking elements, must be detachable. Accordingly, l employ detachable end gages arranged to be detachably secured to the pins 7 8 of the operative end marker elements of the series of marker elements. These gages may take the forms illustrated in Figs. 9 and 1() 'of the draw.

ings in which blocks 17 6 arerecessed and threaded at one end to receive split sleeves 178 interiorly threaded and grooved transversely to form seats for the rear bent ends of spaced spring clasps 180 whose ends project outwardly from the ends of the blocks and are arranged to clasp the portions of the pins 78 immediately above and below the base'plates 50 for the forward ends of the lower marking arms 48 of the marker elements. rllhe split sleeves are spread to grip the ends of the spring clasps by threaded studs 17 9. rllhe sides of the sleeves and the end of one studL (Fig. 9) are beveled to conform substantially to the side of the base 50;

This connection to the pins 78 of the end marker elements will, therefore, detachably pivot the blocks 17 6 on the pins of the marker elements. Studs 182 are inserted in the opposite ends of these blocks and have reduced threaded upper ends carrying nuts. f

66, these portions forming gages arranged toI be engaged by the opposite ends of the flies. As the gage rods are-carried by the blocks 17 6 which are fixedly positioned relatively to the end marking elements of the series, and are guided in the curved -slots 182 in the plates 100, 102, they will occupy the same positional relation to the work in all adjusted positions of the markers.

The position of the gage rod of the gage for the upper end of the ily will be nearer its end marker than the position of the gage f rod for the lower end of the fly since the top button-hole is nearer the top edge ofthe iy than the first or lower buttonhole is to the lower edge of the fly. The lower end gage is, therefore, preferably provided with' a bent plate 186 clamped upon the gage rod by its nut and having its upper arm positioned to lie in the line of the supporting tables 66 to receive and support the end of the fly projecting #beyond the first or lower buttonhole location, so' that it will lie fiat and enable the end gage rod accurately to space the lower end of the iy. o

ln moving the spacer plate 150, it is very desirable that the latter be provided with means for determinately positioning. it with reference to the engaged marker elements and for holding itin the position selected, so that accurate spacing adjustment may be secured yand so that the graded curvature vof the guide plates 100, 102, may be maintained with the spacing adjustment during the marking operations. lt is also desirable to provide means which will facilitate the speed with which thisV may be accomplished without detracting from the accuracy of the adjustment.

Accordingly, thebrack'etv 80 at the forward l side of the bed plate of the machine, includes spaced forwardly extending arms 5188, whose Vends arel formed as journals to receive a shaft 190l (Figs. 4 and 5). The shaft carries one end of a coiled spring 192 mounted in a housing'194, vthe other and outer'v end ofv the'springbeing secured and heldby a pin 196 projecting from one of the arms 188.

- IThe 'shaft 190 intermediateof its ends carries a pinion 198 alined withv and normally' Yengaging a raclrfbar 200 attachedV to theV under side of the central portion 146 ofthe spacer frame. The spring 192, whenfwound,

vnormally tends to'rotate the pinion 198 in Va direction to movethe rack 200 and the Yspacer frame toward the rear of the machine bed, so as to mo-ve the marker elements inwardly toward the central fixed element.

In order to permit the power spring toV perform. this 'operation by a series of v bar of a typewriter.

determinate `steps or rfeeding movements an escapement mechanism is provided. A

Y ratchet 202 is loosely mounted on the shaft 190 and has itshub on theside adjacent the pinion 198 formed with a toothed clutch face204 (Figs. 2`and 4). A coperatingl toothed clutch facelis formed on a sleeve 206 keyed on the shaft 198 and is normally held Vin engagement with the ratchet clutch 204 by means of a spring 208, best seen in Fig. 2,-Y coiled about the shaft between the pinion and sleeve clutch.y Rearwardly of the ratchet wheel 202 an escapement lever 210 is journaled between its ends on a post extending from the arm 188 and carries at its opposite ends, pawls 212 and 214, the lat-` -ter'being spring prsed. y

- Tandem `rock arms218 are loosely journaled on the shaft 190 with a connecting web 220 adjacent their forward ends and with a spacing bar 222 formed at their forward ends and normally extending out beyond the f front of the machine Yfor actuation by the operator in a mannersimilar tothe spacing One end ,ofone of the arms 218 is extendedbeyond the shaft in line Ywith theescap'ement lever 210, as shown at 219, Figs. 4 and'. A; link 224 pivotally connects this extended Vend of the arm 218 with the lower end of the escapement lever. A coiled spring 226 (Figs. 4 and 5) is anchored at oneend to the bracket arm 188 and Vis attached to the extended end of the arm'2l8 tending normally to pull. this extended end f downwardly and maintain the engagement of the pawl 212 with the vratchet.

' Obviously, therefore, when the operatorv depresses the space bar 222 the escapement lever' will Ybemoved to retract the upper pawl 212,fthe lower pawl 214 being thrown into position to .stop theratchet when' it has moved the distance of one tooth and to hold it until .the pawll 212 is againreturnech* Yinto engagementk with a ratchet tooth by the pull of spring 226 against the rock yarm 218 when the spacing bar is released. VThe Yescapement therefore permits the f power spring tov feed the spacer frame and plate step by step to secure'uniformgradations in spacing and to hold the adjustment when j.

The buttonhole flies usually come lto* the operator graded from the largest sizes downwardly. The outer position ofthe spacer frame will position the markers for the-l largestsize of fly, and subsequent operationv of the space bar 222 will to the smaller sizes. Y Y

' TvVhen the spacer frame 144 with its plate 150 has beenV moved inwardly to the inward limit of adjustment, it may be regrade the markers -tracted by means of a bent lever 228 havingr its Yforward end projecting out beyond'the front end of the machine bed andhaving'its 'rear end pivoted beneaththe bed at its central rear portion (see Figs. 3 Yand 14) as at 280, and provided Ywith `anV enlargement 232 (Fig. 5) positioned to engagean aiitifric' tion roller carried at the rear endof a plunger 234 guided in the-'machine bed and extending through-bearings in the bracket 80.

The outer end of the plunger is formed with i Y an upwardly and forwardly extending' head 286 (Figs. 4 and 5) having a 'pin 238 positioned to engage the spacerlframe 144 at a Y point adjacent tothe rack 200. VBy moving the bent lever 228, the spacer frame may be moved vto itsl outer position, restoring the potential ofthe powerspring 192 through Y therotation ofthe pinion'198 engaged" by the raclrbar 200', the teeth of the sleeve. clutch 206 riding over the'coperating teeth movement. through the retraction Y.of the spacer Y frame, a separate yrack n bar 240 (shown in Fig. 4)Y is provided, and is'aperV tu'redadjacent toA one end to .fitupon the `pin 238 ofthe plunger234 so that its rack portion maybe dropped into engagement with the pinion 198. kVlhen'the lever 228jis operated to move the plunger outwardly, the rack bar 240 attached to the plunger and engaging the pinion acts to rotate'thepinion .Y
