AMOS D. ROVE, OF HOLYOKE, MASSACHUSETTS, ASSIGNOR OF TWO-TI-IIRDS TO PETER J. WESTPHAL AND JAMES C. KEOUGH, OF SAME PLACE.'

PAPER-FEEDI NG MACHINE.

To all whom it may concern:

Be it known that I, AMOS D. ROWE, a citizenof the United States of America, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in PaperFeeding Machines, of which the following is a specification.

This invention relates to machines for feeding sheets of paper successively from a pile of such sheets to a paper calender, ruling, or other machine requiring the feeding of paper sheets thereto, the object being to provide an improved machine of this class in respect to the various mechanisms thereof; and the invention consists in the peculiar construction and arrangement of the said mechanisms and devices of the machine, all as hereinafter` fully described,and more particularly pointed out in the claims. y

In the drawings forming part of this specification, Figure 1 is a left-hand side elevation. Fig. 2 is a righthand side elevation. Fig. 2a illustrates details hereinafter described. Fig. 3 is a rear elevation, and Fig. 4 a top plan view, of a paper-feeding machine embodying my improvements. Fig. 4 is asectional view of a part of a paper-holding table and of the n lower end of one of the paper-guiding posts thereon. Figs. 5 and 6 are respectivelyfront and side elevations of the sheet-separating devices. Fig. 7 is a perspective view of certain detailed parts of the devices shown in Figs. 5 and 6 and of portions of certain shaftsof the machine to which said devices are attached. Fig. 8 is a perspective view of the rotating disk and cam of said separating devices, and Fig. 9 is a perspective view of one of the arms which is pivoted on said disk. Fig. 10 is a perspective view of one of the two groups of sheet-feeding devices. Fig. 11 is a perspective view illustrating certain elements of the speed-governing devices of the machine, which are hereinafter fully described.

In the drawings, n indicates parts of the main frame of the machine, of suitable iron construction, preferably.

vertical screw-rods, which are located in said posts 3, the lower end of one of which rods and its step 96 are shown at the lower end of the figure in Fig. 3. The said screw-rods have an engagementwith two nuts 73, (see Fig. 3,) which project through the inner sides of said post 3 and are attached to said paper-holding table 7l. Referring to Fig. 3, it will be noted at the lower left corn er of said figure that said hollow posts 3 are located forward of the rear posts 2 of the machine. 5 5 indicate beveled gears, one of each being secured on the upper extremities of said screw-rods 4. 6 indicates a horizontal shaft supported on the upper end of the machine by two brackets 7 7, which are bolted to theV side of 'said posts 3. cate two beveled gears fixed on said shaft 6 and engaging with said gears 5. Said shaft 6 is driven in one direction, as below described, by means of a belt 9, applied to a pulley 10 thereon.A Said shaft 6 is driven in an opposite direction at the pleasure of the operator by a shaft 12, having a beveled gear 13 on its upper extremities, which gear 13 is engaged with or disengaged from said shaft 6 by a beveled shipping-gear 14, which is provided for stopping the paper-feeding table by hand, if desired. The said beveled gear 14 'is moved into and out of engagement with said gear 13 by means of the shipping-lever 15, pivoted on a bracket on the machine, as shown7 and having a fork engagement with said gear 14, the latter havin g a common spline engagement with said shaft 6, whereby it rotates with the latter and has the requisite sliding movement thereon to provide for its operation, as described. The outer end of said shaft 6, as shown in Fig. 3, is squared to provide for attaching, if desired, a crank thereto for turning said shaft 6 by hand when said gear 14 is not engaged with said gear 13 for adjusting the said paper-carrying table 71 and parts connected therewith.

The main driving-shaft 16 of the machine is located near the lower end thereof, as shown in Fig. 3, and on said main driving-shaft isa driving -ciutch bearing pulley 17, running loosely thereon. A cone-drum 18 is ixed on said driving-shaft 16, and a clutch-pulley 19 is applied to said last-named shaft, having a spline connection therewith and a clutch on 3 S indi- IOO the side thereof adjoining said pulley 17 for engagement with a clutch on the latter. `Said pulley 19 has a grooved hub, as shown, with which a shipping-lever 20, of elbow form, as shown in Fig. 4, engages. The-short arm of said elbow-lever is engaged bya long vertical shipper-lever 2l, which extends nearly to the upper end of the machine, as shown in sev-l eral figures. A shaft 22 is supported to rotate in the frame of the machine above said shaft 16, on which is a second cone-drum 23, and a belt 24 is applied to said two drums 18 and 23, whereby the rotary motion of shaft o 16 is communicated to said shaft 22. An auxiliary frame 25 is pivotally hung on one side of the main frame at the point 26 thereon, (see Fig. 2,) and said frame 25 supports certain operative parts of the machine hereinafter described. A frictional driving-disk 27 is fixed on said shaft 22 and isadapted for alternate engagement therewith of similar frictionally-rotating disks 28 and 29, which are fixed, respectively, on shafts 30. and 3l, which are hung to rotate in said frame 25. A worm 32 is fixed on said shaft v30 and has an engagement with a worm-gear 33, on said shaft 12, heretofore referred to. A pulley 34 issecured on the outer end of lsaid shaft `3l, which is hung in said frame `25, and a belt 9, above mentioned, connects the last-named pulley ,with said v pulley l0 on said lshaft 46` Either of said friction-: disks 28 or 29 may have its periphery engaged by theperiphery of said friction-disk d7, said alternate engagement of said disks 28 and 29 effecting, asbelow described, the movement of the paperholding table -71 up or down. The normal rising speed of the paper-holding table is slightly faster than is required for feeding the sheets, thus insuring at all times, as nearly as possible, a proper position thereof for the lacftion Aof the isheet-feeding devices.

vA. shaft 3 5l is hung in the frame of the Inachine near the` upper portion thereof, and, as below described,'operates to control the yaction of the,Slleet-feeding meclianisin hereinafter described and referred to. A sprocketwheel 3G is fixed on the outer end of said shaft 3,5, and a drive-chain 37 engagessaid lastnamed .sprocket-wheel and a sprocket-wheel l3,8, on' a sleeve 39, (see Fig. 3,) in which said shaft 22 runs freely. Said last-named sleeve has an annular groove therein, with which a shipper-lever4l engages, (see Fig. 1,)whereby a clutch-point on the ,end of said sleeve engageswith la like clutch-point on a collar40, which is secured on the end of said shaft22, whereby by the engagement and disengagement of saidparts 39 and 40 said shaft v3,5 is caused to run or b e stopped. The result of stopping said last-named shaft is to cause a cessationof action of the sheet-.separating mechanism, whereby the transmission ofthe sheets. tothe tape-carrying rolls, andthence toV a calender or other machine, is stopped, Whiley theA mein machine. @Outnues running,

thurs providing, if desired, for clearing the calender or other machine to which paper has been fed of the sheets previously received therein.

Two rolls 42 and 43 constitute, respectively, the lower and the upper paper-feeding rolls, between which sheet after sheet of the paper which is fed from the paper pile 72, as below described, is gripped by said rolls as the paper is supplied thereto by the sheet-feeding devices, as below described. The said roll 42 is hung in the machine, as shown, on shaft 44, and on said shaft is a pulley 45, which is connected with said clutch-pulley 19 on said main shaft 16 bya belt 46. (Shown in Figs. 1 and'3.) Said roller 43 is hung in bearings in the frame of the machine in such manner that it rests, normally, against the surface of said roller 42, and it is subject to more or less of a rising. motion under the action of oneor more sheets of paper that may be passed between them either singly `or unitedly. The belOw-described. mechanism is provided for automatically stopping. the machine when anv excess of, or more than one sheet of, paper is inadvertently fed between said rolls 42 `and 4 3 at thek same time. A shaft 47 is hung in themachine parallel with the axis of said rolls 42and 43, orsubstantially s o, inadjustable bearings 48, attached to the frame of the machine, as' shown in Fig. 3, said adjustment of said bearings being effected by the screws 5,0, engaging therewith, or byany other suitable means. On said shaft 47 are placed .one or more friction-,disks 49, engaging with said` shaft and of greater or less length. rlhe said provision for the adjustment vertically vof said shaft 47 is for the purpose of bringin g the said friction disk or disks 49 thereon .to such position that any abnormal rising movement of said roll 43 during the -operation of the machine, which is caused by the inadvertent passage therethrough of more than one sheet of paper or of any thicker substance than the machine is set to act upon, .will canse the rotation of said shaft 47.

pulley 51 is fixed on o ne extremity of the said shaft 47, and a strap'52 (see Figs. 1 and 3) has .one end thereof wound partially around said pulley 51 and secured thereto. The opposite endof said strapl 52 is attached to the free end, of a pivoted lever 53, (see Figs. 1 and 4,) said lever being pivoted on a support 54, Asecnred to onel of said posts 3 of the frame of the machine. A latch 55 is pivoted by one end to said support 54, with which said lever 5,3 has a link connection, as clearly shown in Fig. 1. The said shipper-lever 2l, by which the machine is started, as below described, andis also, stopped, has a pin 56 therein, one en d of which projects from one side thereof opposite the end of said latch 55 when the latter occupies its normal position, which is that shown in Fig. 1, while the machine is running. The said shipper-lever 21 may be operated by hand by swinging it laterally,y so that said pin shall be disengaged from the end of said latch when it is. desired to stop the machine by hand; but when said lever 2l is set in the position shown in Fig. l, whereby the machine is set in motion, said pin 56 is brought into engagement with the end of said latch, thereby holding the shipper-lever in such position that the machine is caused to be in motion. When, however, as stated, more than one sheet of paper is fed under said roll 43, whereby the latter is abnormally raised, the last-named roll is carried against the disk ordisks 49 on said shaft 47, thereby causing an instantaneous revoluble movement in said shaft, which acts towind up the end of said strap 52 on said pulley 5l, and thereby to pull down the end of said lever 53, to which said strap 52 is attached,and, through said lever, causing said latch 55 to be lifted out of engagement with said pin 56 in said shipping-lever 2l, thereby permitting' the last-named lever to be operated upon by a spring 57, Fig. l, to separate the said clutchbearing pulleys`19 and 17 on the main shaft 16 of the machine, thereby stopping the latter. A gear and shaft holding box 58 is supported on said shaft 35, which shaft runs loosely through said box, one of said boxes being provided for each group of sheet-separating devices, two groups of said devices being ordinarily employed, as illustrated in Fig. et. One of said boxes is also shown in Fig. 3. Said boxes 58 are each provided with suitable bosses on their opposite ends, with which a fork-shaped yoke 59 engages. A rock-shaft 60 is hung for oscillatory motion in the upper part of the machine, as shown in Fig. 3. A plate 61, of suitable material, (metal or hard wood,) is supported in the position shown in Figs. 2, 3, and 2 on arm 62, fixed on said rock-shaft 60. A stationary shaft 63 is rigidly supported in a horizontal position in uprights 64 on the upper part of the machine, and said yoke 59 or yokes are supported on said s-haft 63, as shown in Fig. 3. A gear 65, attached to said shaft 35 to rotate therewith and having a sliding connection with said shaft, whereby said box 58 and gearmay be moved to different positions longitudinally thereon, is free to be so adjusted by freeing said yoke 59 on its supporting-shaft 63. After said box 58 shall have been adjusted, as aforesaid, to a new position it is. again secured in place on said shaft 35 by securing said yoke again on its supporting-shaft 63. A shaft 66, extending horizontally from the front to the rear of the machine, as shown in Fig. 4, is provided for cach sheet-separating group of devices and has a gear connection with said gear 65, whereby said shaft 60 derives a rotary motion from said shaft 35, on which said gear 65 is placed, as described. Said shafts 35 and 66, together with said box 58 and the gear connections herein described between said two shafts, are of well-known construction in machines of this class. To aid in supporting the said sheet-separating devices, which are carried on the extremity of said shaft 66, a supporting-rod 67, which has a or by other suitable means.

sliding connection through or in said box or i boxes 58, has its front end secured Vto said sheet-separating devices by a set-screw 76 or by other suitable means, as shown in Fig. 4t and more plainly in Fig. 7. An arm 68, having a roller pivoted in its extremity, as shown in the several figures, is fixed on the rear side of one of said gear and shaft holding boxes 58, and said arm extends upwardly and rearwardly from said box against the 'front side of said plate 6l. When the upfeed of the pile of paper is too rapid, the end of shaft 66, bearing the sheet-separating devices, is elevated, thereby rocking said box 58, to which said arm 68 is secured, and moving the latter downward against said plate 61. purpose of the engagement of said arm and plate is that upon the undue elevation of the sheet-separating devices,which' maybe caused by the lifting of the pile of paper too high, to force said arm against said plate 6l, so as to swing arm 62 more or less, thereby rocking said rock-shaft 60 and the lever 69, (shown in Figs. l, 2, and 2%) and thereby causing the said auxiliary frame 25, which is connected to said lever 69 by a connecting-rod 70, to be swung upward, whereby the fr-iction-disk 28 on said frame is removed from contact with the friction-disk 27 thereon, thereby stopping all feed of the paper-table either up or down. y

The sheet separating and holding devices illustrated in detail in Figs. 5 to 9, inclusive, are constructed as follows: A metallic frame 7 Ll, composed of two sections NV and L, rigidly secured together, as shown in Figs. 6 and 7 and also in Figs. l and 2, constitutes the supporting elementV for the detailed parts of the sheet separating devices. frame 74, having an arm 75 thereon, which is perforated to receive the lendfof said'supporting-rod 67, and saidffr'ame and shaft are secured one to/the other by a set-screw 76, as shown in Fig. 6 and in dotted lines in Fig. 7, The said frame 74 receives the outer end of said rotating shaft 66 through a suitable bearing therein, as clearly shown in Fig. 7, and on the end of said shaft 66 within said frame is secured for revoluble movement'with said shaft 66 the disk P, carrying on its face the cam K. The said section L of said frame 74; has the vibratory lever 77 hung thereon on the end of said supporting-rod 67, one end of said arm extending under arm 78 on the top of said frame iet andv connected thereto by a spiral spring H. The opposite end of said lever 77 hasconnected indirectly thereto the paperclamping post A. Said vibratory lever 77 has a roll 79 pivoted therein,against which the said cam K on said disk P moves, which constitutes a frictionless roller. Said lever 77 has vibratory motions imparted thereto by the contact of said roll 7 9 with the border of said cam K, and thereby reciprocating vertical motions are imparted to said paper-clamping post A. Said indirect connection between The Said composite IOO said last-named post and said lever 77 consists of' a longitudinally-slotted bar 80. (See Figs.4.and 5.) The connection between said bar 8O andlever 77 consists of abolt 81, pass-v ingupwardly through the end of lever 77 and through the slot in said bar, a washer, as shown, being interposed between said lever and bar. A nut on said bolt S1 secures said lever and bar rigidly to each other. Thus means are provided for adjusting said clamp-y ing-post A at dierent positions from the paper-separating roll e, shown on the extremities of the crooked levers E inv Fig. 5. The said frame-section L carries therein the edge clamp B, which has a post extending vertically through an opening in said frame-sectionL, and carries on the upper end thereof a .roller 83 for engagement with "the border of said cam K, whereby said clamp is at the proper time moved against the paper thereunder. At the side of said clamp-post is set a paper-guiding pin S4, which has a free vertical movement ina part of vsaid frame-sectionL adjoining the said post of said pressure-clamp B, produced by the movement of thetable 71. Said paperguiding pin 84 is supported in said position by the transverse pin m, the object of said pin being to keep the paper always in positionV rela-tive to the said clamp and the sheet-.separating devices. On the said section W of the metallic frame 74 is a depending branch 85 of cylindrical form, preferably longitudinallyperforated and having an adj Listing-screw D entering it from its upper end. Insaid branch 85 under said adj usting screw is va spiral spring fu, whose lowerend is connected to the end of an arm 86 tomove it downward. A roll c is hung to rotate on said arm` S6, and the latter is pivotally hung on an arm 88, secured on said depending branch- S5. The said crooked lever lil/is given a form substantially ask shown to,

providevforpivoting it on the disk P in such a way that the roller e, carried lthereon and supported on. an armV E2, pivoted on said crooked lever, is brought to one side of the lever-pivotnwhen it engages withv the paper. A'corner of said lever is subjected to the backing-up action ofthe spring o, which is more or less yielding. -The said manner of hanging and supporting said leverand roll causes the latter, primarily, to move a short distancewhen first acting to separate a sheet substantially :parallel with the upper surface of the pile of paper, and, secondarily, upwardly and away fromsaid sheet, thus most eifectually producing such separation. ferring to Fig. 2, there is shown an arm 58a, which is attached to said gear and shaft-box 58, which arm has a vibratory movement toward and from shaft 63 above said box, which movement is induced by a similar movement in the latter, and when said arm swings against said shaft it exerts a restraining action againsty the downward movement of the said sheet-separating devices on theforward pile 72 at the rearpf the said sheet-separating.

devices. On each of said arms S9 is a laterally-projecting short arm 90, and'on the ex tremity of each of said arms 89 is pivoted acrooked lever 91. A short connecting-rod 92 is pivotally connected to said lever 91, and

one extremity of said connecting-rod extendsy freely through a perforation in the head of said arm 90 and has a slidin g movement therein, but is retained in such position by suit. able means, so that it cannot inadvertentlyvber disengaged from said arm 90. Saidconnect-` ing-rod 92, between its pivoted end and said arm 90, is screw-threaded and has a nut ,93 thereon, between which nut and said arm90 is a spiral spring 94, which acts to force said lever 91 away from said arm 90 with more or less power, according to the adjustment of' said spring 94. Pivotally connected to saidcrooked lever 91 is a roller J ,preferably of-rubber, for frictional engagement against a sheet o of paper while moving in the direction indicated bythe arrow in Fig. 10, whereby said sheet of paper so engaged is moved from the pile thereof into the feeding-rolls 42 and43 of` the machine. Said roller J is supported on an arm 95, which is pivotally hung on said lever 91. In the lower end of said last-named lever is fixed a block k, of rubber or similar material, for frictional engagement withrthe' surface of said roll J when said roll is forced against said block. Said arm 95 has a limited swinging movement, wherebysaid rollers J, carried thereon, may move away from saidblock 7c when'it shall be carried in the rotation of the devices to a position above or to the right hand of said shaft 35, as illustrated.A

in said` Fig. 10. The provision for limiting the swing of said arm 95, as described, consists in forming a part of the latter-named arm near its pivot-point 0n arm 91, as indicated at 97 in Fig. 10, whereby a shoulder is formed on said arm 95. Two paper-guiding posts 98 are adj ustably connected in vertical positions to said paper-table 7l, as shownin the various figures. Fig. 4illustrates slots in said table whereby-said posts are adjusted` toward and from the center of the pile of pa-f per thereon, and Fig. 4 illustrates the manner of securing the lower end of each of said posts to said table by means of a nut screwed on the lower end of each of said posts, which moves with the latter when adjusted in arabbeted recess on the borders of said slots, whereby the nut is held from turning when said posts are screwed against or from said table to tighten or loosen them. The usual.v

sheet-conveying cords orv tapes shownin Figs.

IIO

1, 2, and 4 are employed for conveying the paper from said rolls 42 and 43 to a paper-calen der or other machine.

The operation of the complete paper-feeding and sheet-separating devices above referred to is as follows: The pile of paper 72 having been placed on said table '71 and the latter having been suitably adjusted vertically to bring the top of said pile into proper relation to the sheet-separating-devices, the machine is started by operating said shipperlever 21. By the above-described devices the said disk P, Fig. 5 and elsewhere, and its connected parts are caused to rotate, and as each sheet-separating roll e reaches a point nearly in a vertical line below the center of said disk P the cam K, attached to the rear side of said disk, operates upon lever 77 to press the clamping-post Adown onto the paper. Immediately after said action said cam K in its forward movement releases said pressure-clamp B, which is holding the sheet at the edge of the pile of paper, as shown in Fig. 5. Said rubber roll e, which is so held from rotation, as hereinafter described, as to have a frictional engagement with the upper sheet o of said pile,now reaches apointwhere it comes in contact with said top sheet of paper, and being pressed down thereagainst by the roller C, operated by the spring if and the pressureadjusting screw D, it moves forward in a straight line 'for an instant andcarries the edge of the said top sheet of paper along with it, as shown. After said roll e has moved forward a certain distance the crooked leverE, which is held down by said roller C, approaches a point where it gradually leaves said roller C, and said separating-roll e not only rises from the sheet o, but also recedes toward the center of the disk P, as illustrated in Fig. 5. The said drawing-in motion of said lever E being accomplished by a spring w,

`connected thereto, as shown in Fig. 9 in the iirst instance, and partially by gravity prevents any danger of wrinkling or breaking the paper after said roll e has completed its primary act-ion thereagainst, as described. As the said rolle approaches a point somewhere nearly vertical above the axis of said disk P it moves over and has a slight peripheral contact with a shoe F, whereby said roll is slightly turned on its pivot or shaft, thereby bringing a part of its surface for contact with another sheet of paper other than that part of its periphery which last acted. The purpose of such alternate rotation of said roll e is to avoid the usual wear of such a paperseparating member which occurs when said member has a part thereof which constantly acts against the paper' and thereby becomes eventually so worn that it does not perform its proper function. Said roll e is now in position to repeat the operation above described, and said roll, while in contact with and moving said sheet o, is prevented from turning on its axial support by a pad m, of rubber or similar material, affixed to the end of said lever E, directly back of said roll, with which the latter has a frictional contact while acting to-separate a sheet, as described. Immediately, after the said roll e begins to leave the sheet of paper on which it has just acted the said cam K presses said clamp B against the succeeding sheet of paper, and said cam then removes the pressure from said clamping-post A, and the latter is then raised by said spring H,A which acts upon said lever 7 7 and allows the paperfeeding devices below described to carry the sheet forward into said feed- rolls 42 and 43'. lt will be noted from the above description that when said roll e pushes up a corner of the paper, as shown in Fig. 5, said pressurepost A is bearing against the sheet and the. presser-foot B at the corner of the pile'is up or slightly separated from the paper. Said paper-feeding between the rolls 42 and 43, act immediately after said post rises. In feeding the sheets of paper after their separation, as above described, and now referring to Fig. 10, the feed-rolls J there shown, being carried over the paper at a higher rate of speed than were said separating-rolls e, act to draw the sheet of paper away from said roll e, thus removing the pressure of the roll J which the latter has exerted against the rubber pad k and thus allowing said roll to turn on its own axis, so as to present a new surface to the next sheet of paper. The movement of the sheets of paper under said roller J whereby the above action thereof results is caused by each of said sheets 0 being caught by the said feed- rolls 42 and 43 and drawn away from under said roll J at a speed faster than they were moved by the latter, thus swinging said rolls in the direction in which the paper moves. Should two or more sheets o lof paper enter the feed- rolls 42 or 43 together, as heretofore referred to, the top roll 43 is lifted and the machine is stopped through the action of automatic mechanism already described.

The main driving mechanism of the machine consists of said main shaft 16 and the shaft 22, carrying, respectively, the said conedrums 18 and 23, which are united, as aforesaid, by a belt 24. To provide for varying the speed of said shaft 22 proportionate to the requirements of the machine in respect to the manipulation of sheets of paper of varying lengths, the said belt 24 is adapted to be shifted or shipped on saidrco'ne-drums by means of a shipper-yoke 99, (see Figs. 3 and 11,) having belt-engaging arms 100 thereon extending in opposite directions opposite the edges of said belt, and on said arms are freely-rotating frictionless sleeves, as show-n, whereby the said belt is given a freer action when acted upon to be moved on said drum by the shiping device. Said shipper-yoke 99 is provided with a hook 101, attached by a bracket, as shown, to said shipper-yoke. On the lower end of said hook 101 is a turned-up lip 102,

devices, which carry the paper IOO IIO

and on the upper end of said hook is an arm having a depending index-finger 103 thereon. A graduated bar 104 is secured across the rear end of the machine, as shown in Fig. 3,

`having graduation-marks thereon indicated by figures, which denote the shipperposition of the belt 24 for imparting proper motion to the operating parts of the machine when sheets of paper of the length denoted by the igures on which the indicating-pointer 103 rests are to be operated upon. The said bar 104 is engaged at its opposite edges by said lip 102 and finger 103, said finger being adapted to be brought to said indicating positions on said bar, as shown, by means of a screwrod 105, havingsuitable bearings in the frame of the machine and extending through a screw-threaded portion of said yoke, as shown in Fig. 11. A crank on the end of said screwrod,as shown, provides means for rotating said rod and thus moves the said yoke and belt 24 to different positions for the purpose stated. The said screw-rod 105 is provided with proper collars thereon, as shown, to prevent any endwise movement thereof. In shipping a belt on the cone-drums, as stated, it is found desirable that the shipper devices should move as near as may be in a line coincident with the adjoining face of the drum, and to that end the said shipper rod and bar 104 are arranged on the frame on an incline,I as shown in Fig. 3.

A vertically-arranged lever 106 is pivotally hung on said frame 2 of the machine, as shown in Fig. `2the upper end of which is adapted, if desired, for engagement with the under side of said auxiliary frame 25, when the lat- Y,ter ,occupies the upward position shown in said last-named ligure, for holding said frame in said position independent of other described devices. The lower end of said lever is bent inwardly, as shown, to bring said end more or less in the path of the downward movement of the paper-table 71, whereby the latter,when descending inadvertently too low, strikessaid bent end and swings said lever on its pivot and carries its upper or frame-engaging end into a notch 107 in said frame, thereby permitting said frame to drop suiiiciently to remove the disk 34 away from the drivingfdisk 27, and thus stop the downward movement of the table.
