' Specification of Letters Patent; Patented Aug. 31, 1909- Application filed November 12, 1903. a Serial No. 180,827.

To all whom it may concern:

Be it known that I, WALTER L. DIXON, a citizen of the'United States, residing at Bosscription, in connection with the accompanying draw1ngs,1s a specificatlon, like characters on the drawings representing like parts.

My invention relates to machines for folding the blanks for, that is the members which go to make up, collars, cuffs, and other similar or equivalent articles, preparatory to the assemblage and stitchingof the "same in and to form the completed article.

While comprehending various improvements in the general construction and. opera tion of a machine for thispurpos'e, my in vention relates mainly to means for intro ducing the blanks and presenting the same to the folding devices, and also to means for automatically removing the foldedartic1e or blank from the machine Thesepermit the operator, after having positioned a blank or blanks in the machine, to take his'attention from the machine, leaving it to fold and re-' move the blanks, while he gives attention'to the preparation of further blanks for the next succeeding folding operation; thereby greatly increasing the output as compared with machines which require the, operator himself to attend to the removal of the folded bhnks or articles from the machine bea fore he can place therein new blanks for the next succeeding folding OPGI'fltlO-Il.

The nature of my invention 1n 1ts varlous aspects will be best understood from adescription of the construction and operation of a machine illustratmg one embodiment thereof; it being understood, however, that Fig. 2 is a longitudinal section on the dotted line 22, Fig. 1. Fig. 3 is a cross sectional detail on the dotted line 3+3, Fig. l, showing the yielding blank support, the die or templet over which the edges arepressed, and the folders in the positions inwhich they stand at the time of .positioninga blank preparatory to the folding, a blank being shown as upon its supportinreadiness for the folding. Fig. 1 is a similarsectional detail showing the die or templet dropped upon thevblank to hold the latter firmly in positioniupon its support. Fig. 5, a similar sectional detail showmg the die or templet as having'further descended, pushing before it the yielding blank carrier or support and as havingzpresented the blank to the edgefolders preparatory to the operation of the latter upon 'the. blank. Fig. 6, a similar sectional detail showing the edge folders withdrawn and the folded blank raised above the level of the folders preparatory to its removal from themachine, the infolded and pressed edge being shown slightly open for clearness." Fig. 7. is a top or plan'view of the machine as a whole; this view particularly showing the means for contracting the die or templet after the infolding of the edges of the blank and to permit the folded ;edges to be compressed. Fig.8 is a front elevation of the machine as a whole, with .the frame legs broken off and the nipper mechanism removed. Fig. 9 is a vertlcal j cross section of the parts shown in Fig. 8,

the section being taken on the dotted line,

1 99, Fig. 7. Fig. 10 is an end elevation of the machine shown in Figs. 8 and 9, this figure illustrating mainly the driving and shipper mechanlsms. Fig. 11 is a detail looking down upon the die or templetcarrying cross-head, showing the parts differently positioned as compared with Fig. 7. Fig. 12 is a sectional detail showing manner of adjustment of the rods, 90. Fig. 13, a detail showing the contractible die or templet detached; and Fig. 14, a cross sectional detail of receiving table depressing means.

Similar-characters of reference designate corresponding parts in the several figures.

In the particular embodiment of my invention selected for the present illustration, referring particularly to Figs. 1 to 5, inclusive, the blank or article 6 to be folded, here'shown as a collar. top and which may be linen, cotton, or other fabric or material,

end stops or guides, 12, by which the blank is centered endwise in the machine. At its rear or inner. edge the blank also overlies other portionsof the supports, 11, whlch are ispositioned' upon a depressible support, 10, .with its ends overlying fixed supports, 11, =-which latter are provided with adjustable provided thereat with back stops, 13, for

positioning the blank laterally in the machine 'The fixed supports 11 areas shown nOn-depressible'in contradistinctlon to the 'depres'sible character of the support or plat- .form 10. Said non-depressible portions 11 are not only end supports, (supporting the blank ends while platform supports the blank center) but also have'a positioning function as above explained. It..should be noted, as seen in Fig. 1,"that the non-depjressible portions 11 support and position not only the blankiends but somewhat ,of the blank rear side;.whereas as shown said portions 11 do not similarly extend around in the front. On the contrary they terminate in front at the very ends, thus leaving a freeor open space in front between the two portions 11; which is useful, as Wlll hereinafter appear,-in permitting the folded blanks to; be withdrawn forwardly by anoutfeeding mechanism, when such outfeeding mechanism is'used.

The yielding Support, 10, is. itself provided S with stops, 14, behind which the blank is placed and by which it is prevented from moving away from the back stops, 13.'- Both the backstops, 13, and front stops, 14, are

adjustable in-suitable manner, to provide for blanks: of different sizes and shapes.

J support and the confined blank to. the level ShOWII in Fig. 5, with. the projecting edges of the blank resting upon. the bed plate, 16, and turnedupward-against the edges of the folders, .The opening in the bed plate, 16, coincides substantially with the outline of the support, 10, as viewed in Fig. '1. j 'Ih'ecorner folders,17, and the back folder, '18, are now-advanced to lay the projecting upturned edges of the. blank inwardlyover.

and upon the top surface of the templet,

. aftenwhich the said templet is first raised slightly, to clear the blank upon the support and is then contracted and withdrawn. forwardly from within the. infolded edges, after which the edge folders, 17, 18,. and the .bedplate, 16, are brought together, for example as shown, by depressing the edge folders, to compress and-set the fold, preferably in the presence of heat. This heat may be conveniently provided bymaking a steanr box of the bed, 7 5, upon which thebedplate,"

1.6, rests and is. secured. The edge folders are now raised, slightly to. free themfrom the. infolded edges of the blank and are withdrawn to ermit the; depressible support 10 t o begra sed into its position, Fig. 6,

tofcarry the folded blank above the level of the-edge folders, where it is seized by a pair .of nippers, 108105, Figs. 7 and 9, and with drawn edgewisefrom the machine; leaving the yielding support in readiness to receive a new blank for anew folding.

The depressible blank support 10 (see Fig. 9) is mounted upon a central post which is vertically adjustable in a socket 21. in the end of a hook shaped arm 22 loose on the cross-head shaft 23, which latter is mounted in suitable bearings in and at the back of the machine frame, A. This hook shaped arm 22 has a rearwardly extended short lug 24, (Fig. 9) to which is jointed a depending rod 25 which is connected with the rear end of a lever 26, fulcrumed at 27 in the machine frame. The front end of this lever 26 is provided with a roller stud 28, which is operated by a path cam 29 fast on the main shaft 30, the latter journaled in the frame A of the machine. In the present instance, the depression of the blank support 10, under the action of the descending templet, is provided for'at the point of connection between the rod 25 and its lever 26, just described. The rear end of this lever 26 is forked, and carries the swinging block 31, through which the lower end of the rod 25 is loosely passed; said rod being provided above said swinging blockwith one or more lock nuts 32; and below said block the rod is provided with one or more nuts 33, and between the latter and the under side of said lever is interposed a spring 34-. Yielding of this spring permlts'the blank support 10 to be depressed independently of its controlling cam 29, the jtension of the spring, however, being sufiicient to permit the said cam, through its lever 26, to elevate the blank support to its lnormal position when the templet is not opposing it.

The templet which descends upon and clamps the blank uponv its support 10 consists, 1n the present embodiment, of two thin plates or members 15 and 15 Fig. 13, havmg overlapping rear portions whereby they .may be moved one toward the other for contractingthe templet; or extended one away from. the other for expanding the templet in a manner well understood by those skilled in this art.

Referring to Figs. 8, 9 and 18, the two parts 15 and 15 of the particular templet shown, are fast upon the under sides of the blocks 35, which are horizontally slotted at their upper edges to receive the screws 36,

by which. said blocks are adjustably screwed to the depending ribs 37, on the slides 38, carried by the movable cross-head 39, of the machine. The screws 36 and the slots in the blocks permit the said blocks and the I templet parts carried thereby to be adjusted toward and away fromeach other for contracting or enlarging the templet for different sizes of blanks to be pressed.

The templet slides 38 are provided at their upper sides with the diagonal guides 40,

which latter enter corresponding guide-ways in the under side of the cross-head 39. The templet slides 38 also carry two guide screws 41, see Fig. 7, which rise through diagonal slots in the cross-head 39, the direction of said slots corresponding with the direction of the guides 40 previously referred to. The

of the cross-head 39, said sliding plates being slotted from front to rear to receive the shanks of said screws. These two sliding plates 42 are connected by links 43 with diametrically opposite points of thecentral disk 44, the latter being loosely mounted upon the central stud 45 on the cross-head. In a radial slot 46 of said disk is adjustably clamped the crank pin 47; to whiohis jointed the connecting rod 48, operated from a slide bar 49. This slide bar is adjustable as to its length, and at its front end has a hearing on the cross-head, while its rear end is.

forked to straddle the cross-head shaft 23 heretofore referred to. The cross-head shaft 23, see Figs. 7 and 9, also has fast upon it the arms, 50, which reach out to and support at their free ends the cross-head 39 referred to, whereby rocking of the said shaft will cause said cross-head and its attached parts to be swung upwardly or downwardly. This constitutes a convenient means to move the cross-head and templet down and up, toa roller stud 55, which travels on a surface.

cam 56-, which cam isshown near the left of the machine, Fig. 8, and is fast on the main shaft 30. Thus, rotation of the main shaft acts through cam 56 to swing the cross-head 39 at the proper times, from its elevated dotted position Fig. 3, intothe position of Fig. 4, and thereafter into its lowest position, Fig. 5, as required for the folding operation heretofore described.

Referring to Fig; 7, the forked end slide bar 49 has at its side a roller stud 57, see also Fig. 9, which travels in a path cam 58, which is sleeved on the cross-head shaft 23, and is provided with a gear 59. for driving it. This gear 59 is driven by a gear 60, see Fig. 9, on an intermediate shaft 61 mounted in the frame, and gear 60in turn is driven by a gear 62, Fig. 8, on the main shaft of the machine.

contraction of the templet.

. the blank.

Thus, rotation of the main shaft operates at theproper times through the intermediate gear and the cam 58 referred to, to reciprocate the slide bar 49, Fig. 7, to cause its. connecting rod 48 to give a rotary,

reciprocatory movement to the disk 44. This i causes. the said disk, through its connecting links 43, to separate and bring together the slide plates 42 and their connected templet parts, 15f and 15 for the expansion and The diagonal guides 40 enforce a diagonal or convergingdiverging movement of the two templet parts, so that the said parts move outward or toward the front of the machine si1nultaneously with their contracting movement or toward the other. This has the effect not only of withdrawing the ends of the templet parts from the end folds of the blank, but also of withdrawing the rear edges of the templet parts from the back folds of the blank. F0Zders.Having described the mounting and movements of the depressible blank support and the construction and mode of operation of the expanding and contracting templet, I will now describe the construction and mode of operation of the folders, 17, 18, Fig. 1. The diagonally movable endfolders, 17, are substantially Lshape and oppositely positioned, so that they will operate around upon the ends and rear corners of For ordinary corner folding, where the corner is to be rounded, as here 'shown, these end folders 17 may be moved simultaneously thereby to fold the ends and end portions of the rear of the blank at once. If the corners are to be square, and are required to be looked, as is frequently the case, these folders wouldbe differently constructed and operated, first in one direction and then in another, in a manner well understood by those conversant with the art. Since it is immaterial to my present inventionwhich kind of folders are used, I have selected the simple form shown, namely, for folding round corners; it being understood, however, that my invention in no wise restricted to the particular construction, form or manner of operation here shown and described.

To produce the simultaneous, diagonal or converging movements of these end folders 17 ,I have provided them respectively with cross slots 63, which permit them to be moved simultaneously forwardly while being moved inwardly, thereby giving a resultant diagonal movement which is a mean arms are slotted longitudinally to receive the clamp screwsv 66," by which said, arms are adjustably connected to the blocks 67, which blocks are hinged atx68, in and to the upper ends of the levers 69 fulcrumed at 7 O on the frame" of the machine, and having their lower" ends provided with roller studs 71,

which studs travel in the barrel cams 7 2 fast V the barrel cams 72- to rock the levers 69,

and thereby moves the end folders 17 transversely, or from right to left of the machine. To give these end folders the necessary simultaneous front and back or cross movement, see Figs. 7 and 9, I have provided them with rearwardly extended portions 76, each of which carries a pair of studs 77. These studs 77 rise through long slots 77 formed in the flange of the folder carrier 78, which latter is in the shape of a long bar or head. This carrier has a pair of rearwardly extended lugs 79, see Fig. 9, which receive the threaded shanks of blocks 80, the latter being slotted at their under sides to receive the pins 81, on the upper ends of 7 arms 82, which arms are fast on the shaft- 27 heretofore referred to. This intermediate shaft 27, see Fig. 10, has at its end a depend- 1ng arm 88, carrying a roller stud 84:, which -stud travels in a path cam 85, fast on the main shaft 3O; whereby rotation of said main shaft will rock said arms 82, and cause the folder carrier 78, to advance and recede simultaneously with the endwise in and out movements of the arms 65, giving to the end folders a resultant diagonal, converging movement, which is the mean between the in and out and advancing and receding movements. During the endwise, in and out movements of these folders 17, the slots 63 permit them also to advance and recede f crosswise relatively to their studs 64, and

similarly,thelong slots 77 permitthe said folders to shde endwlse under the movement by the said arms 65, simultaneously with the cross movement described. Since these folders 17 are carried wholly by the folder carrier 78, on which they must also move endwise of the machine, and since the operating parts are all maintained in a heated condition for the better pressing of thefolded edge, it is desirable to provide eflicient devices which will permit free movement of the folders, notwithstanding the heated condition of the parts, which forbids the use of a lubricant. For this purpose, see Fig. 9, the under side of the carrier head 78 is slotted lengthwise to receive a series of roller studs 85, mounted upon the top faces of the folders, and which rollers preserve the alinement of the said folders from front to rear of the machine without the use of a lubricant. Said folders are also provided'with elbow arms 86, which reach upward at the rear of the folder head 78, and are there provided with roller studs 87, which latter travel in a horizontal trackway in the rear edge of the said folder head and which serve to support the said folders and to hold them at the proper level, while permitting free sliding movements thereof, also without the use of lubricant.

Referring now to Fig. 1, the back folder 18 is clamped by screws 88 to the folder carrier 78, and is adjustable longitudinally thereon in the slots 77 thereof, referred to. This middle back folder 18 has no endwise movement; merely an advancing and receding movement over the rear edge of the blank.

The slots in the folder moving arms 65, at the ends of the machine, permit the end folders to be adjusted toward and from each other for different lengths of blanks; and a back folder 18, of greater or less length, may be used as required to fill in the space between the end folders when they are in their closed positions one relative to the other.

Having described the means for manipulating the folders to lay the'edges of the blank over and upon the templet together with the'means for collapsing or contracting and withdrawing the templet from the infolded edges, 1 will now describe the means for compressing or set-ting the folded edges. As heretofore stated, this is accomplished by pressing the folders and the bed plate one toward the other. the folders are pressed downward toward the bed plate.

Referring to Figs. 1, 7 and 10, the folder carrying head 78, near its end, is notched or raised at its front edge to receive the pivoted blocks 89, through which are passed the upper, threaded ends of the presser rods 90. To provide for convenient adjustment of the ends of these rods 90, in the said pivoted blocks, the threaded ends of the said rods, see Fig. 12, are screwed into the illternally threaded shanks 91 of nuts 92, which shanks extend down through said blocks for the purpose. Lock nuts 93 are. screwed upon the lower ends of the said shanks at the under side of the pivoted. blocks and other lock nuts, 93, are screwed upon 'the ends of the rod above the shank nuts 92. Thus, by slackening the lock nuts and turning the shank nuts 92, the ends of the rods may be adjusted in and relative to the pivoted blocks without turning the rods themselves. These rods 90, see Figs. 8 and 10, are suitably attached at their lower ends to the ends of a yoke 94:, hung 011 the shaft In the present instance, r

54 and provided with a forwardly and upwardly extending arm 95, which. arm is procam 96 fast on main shaft 30.1 i

In the operation of the machine, after the templet pushing before it the yielding blank 1 support and the confined blank, has deseended into the position shown inFig. 5,

the cam 96, last mentioned, operates through the rods 90, just described, to lift the folder carrier 78 slightly, thereby to lift the folders 17, 18, so that they will clear or allow for the thickness of the templet in. the fold ing of the'edges of the blank over the templet. After havingfolded the edges of the blank inwardly over and upon the templet, they are further lifted slightly by: the cam.

96 to permit ready withdrawal of the collapsing or contracting templet; after which the said cam acts through the said rods 90 to pull down upon or depress the folder carrier 78, and its folders 17, 18, to cause 1 the latter sharply to crease or set the infolded edges of the blank in the presence of heat.

The folders are held in their depressedor setting positions for the desired time, determined by the cam 96; after which they are released by the said cam, and raised; free and clear of the now folded blank, leaving the latter free to be withdrawn by the outfeeding devices or nippers, which I will now describe. V

' Outfeedng (Zeoi0es.Referring to Fig. 9, there is mounted in and, at the front of the end frames A, a shaft 97, upon which, near its middle, is loosely mounted the hub of a carrier arm 98, said hub having an inwardly extended lug 99 which carries a pin 100. This pin engages the forked end of a lever 101, which is fulcrumed'at the rear of the machine upon the shaft- 5 1, and is provided in- I termediate its length with a roller stud 101 which stud travelsin a path cam 102, see Fig. 8, on the main shaft 30, so that rotation of the main shaft at-the proper times, determined by said cam lever 101, swings the said carrier arm 98 toward and away from the blank. being folded in the machine. The carrier arm 98, at its upper end, see Fig. 7, is forked to provide bearings for the ends of the short shaft 103. Upon this shaft and between the said bearings are fixedly secured the finger supports 104-, to which are rigidly secured the under fingers, 105. I

Pivoted to the finger supports at 106 are the top finger carriers 107, to which are connected the top fingers 108, said top finger .car riers having rearwardly extended arms 109, which are connected by a rod 110; whereby said carriers and their respective top fingers may be swung about the pivots 106 to give to the said top fingers opening and closing or releasing and nipping movements relative to the under fingers 105. To produce these opening and closing movements I have provided a small table 111 upon which the .rod 110 ,ispressed by a spring 112, and this table 111 is mounted upon the upper end of a rod 113, the lower end of which rests upon the are shaped end of a cam lever 114, said lever being fulcrumed upon the shaft 61 pre viously referred to, and said cam lever havin'g intermediate its length a roller stud 115 which travels on a surface cam 116 on the main shaft 30, between the cams 96 and 102. The spring 112whichpresses the rod 110 upon the tab1e111, acts also to maintain the table carrying rod 113 down in operative engagement with the are shaped cam lever 114-; so thatatthe proper times the cam 116, just described, by dropping the arc-shaped end of its; lever,-will permit the lower end of the rod 113,.in whatever radial position the lever may be, also to drop and, by dropping the rodl-lO, cause the top nippers 108 to be raised or opened into their dotted positions, Fig. 9. Conversely when the said cam lever, 114:, is raised by its cam it will act through the rod 113, in whateverposition the latter may be, to raisethe rod 110, and close the top nippers 108, upon the bottom nippers 105.

The nippers, whether closed oropen, may be raised or lowered, to bring them to the required levels for seizing and releasing the folded blanks,by rocking the shaft 103, upon which they are mounted; and for this purpose I have provided the said shaft with a collar having an arm 117-, to which is'conmoves relatively to one or more stop nut-s 120 on the stop rod 121, which rod projects laterally from said arm 98. While the spring 118 tends normally to hold the nippers in their depressed or-:lowermostpositions, the cam lever 114, iff raised, will .act through its rod 113, and the table 111 upon the rod 110, to lift the closed nippers against the action of the said spring 118, the lifting action tending also to maintain the nippers tightly closed during the lifting movement. Thus, the nippers'are raised and lowered under the control .of the cam lever 114, and are also opened and closed under the control of sald lever, the stop arm 119 and nut or nuts 120 serving. to fix the possible lowest posltlon of the nippers, whether open or closed.

In the operation of the machine at or about the time when the folders are depressed to set or compress the folded edges of the blank, the nipper carrying arm 98 is caused by its cam 102 to advance toward the blank, and, as it advances, the cam leverllt is dropped by its cam 116 to cause the said nippers to open, as shown in dotted its original position, carrying the folded blank upon it, the open nippers reach the w front edge ofsaid yielding support, the botthe said support.

, tom nippers entering under and-the top nippers passing over the blank which rests upon 7 The support is notched at 122 to clear the nippers, so that when they seize'theblank' they will not-seizealso the support upon which the blank rests. Having reachedtheir innermost positions shown in dotted lines Fig. 9, the camlever 114 is raised by its cam, and through rod 110 closes the nippers, causing them to seize the folded blank, after whichfurther lifting movement of the rod 110, by the said cam lever, being unable further to close the said nippers,

acts to lift the closed nippers bodily'and sufliciently'to raise the front edge of the folded blank clear of the front and end positioning stops 14 and 12, Fig. 1. The nipper carrier arm 98 is nowmoved, by its cam, away from the bed of the 1nach1ne,-carry ng with it the folded blank, and leaving the depressiblesupport 10 ready for a new blank to be placed immediatelythereon for a new I folding operation.

Aslthe nipp'ers' carrying the foldedblank move outwardly away from the bed, they are at the same timealso opened and lowered by the cam'lever 114:, to depositthefolded blankupon the table 123, or upon the pile of folded blanks thereon. The

. foldedblank is deposited between four up- FAQ right posts 124, which are mounted on the .fiXed shelf 123 and rise above said table so that withdrawal 'of the under nippers from beneath the folded blank in the further outward movement of the nipper earrier'98 will not disturb the pile of blanks upon the said table, nor displace the blank about to be deposited onthe said table. It

is clear that the level of the table 123 must J'be gradually lowered, as the pile of folded blanks is built up thereon; in order that the topmost blankof the pile may always be deposited at substantially-the same level, whether there be one or more folded blanks "in'thepile. To accomplish this, referring to Fig. 8, I have removably mounted the said table 123'upon a rotatable post 125, in

. which post is cut a spiral groove 126 of high pitch. This spirally grooved post drops through the shelf 123 and to the under side "of said shelf is pivoted at 124: an L-shaped lever 125?, see, Fig. 14, one end of which enters the spiral groove 126, it being retained therein by a spring 127. Immediatelybelow the lever 125 is a collar128 loosely surpost and will cause it to be screwed upward or downward accordingto the direction of.

rotation while maintaining a sliding engagement between its feather and groove referred to. For rotating this collar 128 I have provided the same with fine ratchet teeth 129, which are engaged by a spring pressed pawl 130, on a rod 131, said rod mounted to slide longitudinally in bearings 132, Fig. 8. This rod is pressed by a spring 133 against the free end of a depending arm 134 on the shaft 70, which shaft carries the arm that reciprocates one of the end folders, so that at each outward movement of the end folders, the rod 131 is moved inward, and, through its pawl referred to, rotates the collar 128, and thereby causes the table to be slightly lowered to compensate for the increased depth of the pile of folded blanks thereon due to the addition of the topmost blank thereto.

The number ofteeth engaged by the pawl at each reciprocation of the rod 131, and the consequent rotative movement of the collar and lowering of the table, may be determined by suitableineans, as, for instance, by an adjusting screw 135 in the lower end of the arm 134, which screw abuts against and moves rod 131, and whose adjustment therefore determines how far said rod will vibrate and therefore how many teeth the pawl 130 will pass over in each vibration.

To assist this a pin 131 may be provided on the rod 131, which pin abuts against the bearing 132 at the left, and serves as a check to the backward movement of the bar 131, thus causing a. lost motion bet-ween the rod 131 and screw 135, which lost motion is rendered variable by the adjustment of screw 135.

After having folded a given number of blanks representing a given lot or lots of the same, they may be removed from the table and to facilitate quick return of the table to its normal elevated position preparatory to the placing thereon of a new lot, the operator may withdraw' the spring controlled lever 125 from engagement with the spiral groove of the post 125, and may then slide the said post upwardly past the said lever, and thereby at a single movement restore the table with its pile of blanks to elevated position; after which he may permit the said lever again to engage the said spiral groove for the control of the next descent of the said table.

The positioning posts 124: are adjustable in the stationary shelf 123, which is slotted to permit them to be moved toward and away from each other to accommodate different widths of blanks; they being held in adjusted positions by thumb nuts 136.

After the table carrying the pile of folded blanks has been elevated as described, the table may be lifted from its position and clear of the upright guide posts 124., and placed upon any shelf or place conveniently at hand; said table being provided with suitfrom between the'stationary guide posts 124,

any suitable means may be employed, and, if desired, a plurality of such tables may be used so that while one pile of blanks is being removed and tied up into a bundle, another such table may be inserted to receive a new pile of folded blanks. I i

The depressible support 10, of minimum size, will ordinarilysufiice for the larger sizes of blanks to be folded thereon, because in every case the edges and ends of the blanksare supported upon the end supports 11, which are made longitudinally adjustable, see Fig. 8, by means of set screws 160 passing through slots 161 therein. My invention, however, i comprehends the use of depressible tables of different or variable sizes, whenever it is found desirable to use the same.

Turning now to Figs. Sand 10, the main shaft 30, has mounted upon itsendya worm wheel 170, in mesh with and drivenby a worm v171 on a cross shaft 172, said cross shaft journaled in bearings 17 3 in the frame.

This cross shaft carries fast and loose pulleys 174. and -17 5, suitable shipper mechanism being employed for shifting the driving beltfrom one to another of said pulleys. Inthe present embodiment of my invention this shipper comprises the parallel arms 175 between which the belt is passed, said'arms being mounted on a shipper bar17 6, which in turn is mounted to slide in suitable jbear- A sprlng 177;1s-'1nterposed between one of StilCl bearings and a ings in the frame.

loose collar 178 seated against a fast collar 178 on said shaft, and tends to throw the said shipper normally over to the loose pulley. The shipper bar is moved to the right, Fig. 10, upon the fast pulley. and in opposition to said spring, by the arm 179 of a rocking treadle 180, pivotally mounted at181 in a suitable bracket or support. Rocking of the treadle throws the arm to. the right, Fig. 10,

and places the shipper opposite the fast pulley, where it may be held by continueddepression of the treadle to produce continuous operation of the machine; requiring the operator to feed the blanks to it while the machine is in motion. To stop the machine at the end of each cycle of movements or after the fold of each blank, when the treadle is not maintained continuously depressed, I have provided upon the shaft 61', Fig. .10, a shipper cam 182, coeperating with which is a lever 183, fulcrumed at18t, and'connected at its lower end, by a link 185, with the loose collar 17 8. Assuming the treadle to have been rocked in the directionof the arrow shown, Fig. 10, and the shipper'bar moved to the right, as the machine starts, the end of the lever 183, mounts upon the largest diame ter of the shipper cam 1 82, and if the treadle be released, the said cam will still hold the said lever 183 in its outermost position, with the shipper opposite the fast pulley, until the completion of the folding of a blank or set of blanks. If the treadle be not still depressed, the end of the said lever 183 will then drop into the V-shaped depression in the shipper cam,and permit the spring 177 toreturn the shipper bar to the left, Fig. 10, and throw the belt upon the loose pulley, 175.

It is occasionally necessary to turn the machine by hand, either forward or backward, and for thispurpose the end of the worm shaft 172 is squared, see Fig. 8, to receive a crank handle by which it may be rotated and the machine operated. Should the machine, however, be turned in either direction by hand, a sufficient distance to raise the cam roll of lever 183 out of the V- shaped depression in the shipper cam, said lever would throw the belt upon the fast pulley and snatch-the machine from the control of the operator with possible damage that might result therefrom. To obviate this, I have provided, see Fig. 10, a swinging lock, having a projection 191 which, before the machine is operated by hand, is dropped behind the hub of arm 17 9, on the end of the shipper'bar, which has been first moved into its position to carry the belt uponthe loose pulley. Thisholds the said bar against any movement which could carry the belt upon the fast pulley during such time as the machine is being operated by hand, and the belt cannot be shifted until the lock is positively disengaged prior to restoring the machine to power operation.

Referring to Fig. 10, I have provided the shaft .23 with a rearwardly extended stop arm 200., When the arms 50, carrying the templet, are thrown over toward the back of the machine about the axis of the shaft 23,this stop arm200 contacts with the shaft 61 to limit the swinging movement of the said arms 50, and supports the same until restored to normal position.

The above described machine, it will have been seen, is a creasing as well as folding machine, since the folds are pressed and creased before the blank comes out of the machine; the bed ,on which the blanks rest while being folded may be termed a table; the blank edges extending beyond the templet may be termed flaps, which flaps are folded onto the body of the blank; the sup- .port 10 and its actuating mechanism constitute means for automatically raising the fabric-body ofi the table; the grasping fin- 97 until they can engage the raised fabric blank, when the jaws are closed, as described,to clamp the fabric blank, and they then move back and carry it to the front side of the machine, when the jaws open and drop the blank. 7
