' The main frame of the machine comprises four vertical posts 1, 2, 3, and 4, respectively. Connecting the upper ends, respectively, of the posts 1 and 3 and 2 and 4 are two horizontal

parallel plates

5 and 6. Connecting the lower ends of the posts 1 and 3 and 2 and 4, respectively, are two horizontal parallel plates 7 and 8. A transverse horizontal drivingshaft 9 has its ends rotatively mounted in the posts 3 and 4, respectively. On the left end of the said shaft as viewed in Fig. 3 is mounted and rotatable therewith a drivingpu ley 10, which may be rotated by any convenient means. Rotatively mounted on the shaft 9 is a roller 11, over which passes an endless cord or tape 12, which is also supported and driven lengthwise by means of a roller 13, mounted on and rotatable with a transverse horizontal shaft 14, rotatively mounted .in the upper ends, respectively, of the osts 1 and 2. Upon the left end of the sha t 14 as viewed in Fig. 3 is mounted and rotatable therewith a pulley 15, by means of which the shaft 14 and roller 13 are rotated, rotation of the pulley 15 being acquired in any desirable manner. The endless cord or tape 12 is wound backwa d and forward upon the rollers 11 and 13 in a manner forming a series of loops, the upper sides of which connect the uppcs sides of the rollers 11 and 13 and support the sheets of paper that are delivered thereon from the forwarding-tapes, hereinaf tcr descrbed. The cord or tape 12 is driven by the roller 13 in a direction denoted by the arrows in Fig. 3. Rotation of the cord 'or tape 12 is imparted by means of a twisting mechanism 16, the pal ticular construction of which is described and claimed in the sheetregistering' application above referred to. The loops forming the cord or ta e 12 have their upper sides disposed parallel with each other, and the spiral movement of the cord or tape will carry the sheets detached from the pi e lel'igthwise toward the roller 13 and latorally to and against a side guide consisting of one or more vertical projections 17 on the upper edge of the plate A further dcscriptionof the sheet-registering mechanism is not deemed necessary, as such mechanism is fully described in the aforesaid application form 19 will be raised.

for a sheet-registering machine, filed of even date herewith.

I will now give a brief description of the mechanism for supporting and elevating the pile of paper, a complete description of the construction of such mechanism being given in the aforesaid application for a table-elevating mechanism, filed of even date herewith.

The pileof paper (denoted by 18) rests upon a horizontal platform or table 19, disposed between posts 1 and 3 and 2 and 4. The forward end of the table extends a considerable distance in front of the posts 3 and 4. The I .platform or table 19 is supported as follows:

A horizontal shaft 20 is rotatively mounted at its ends in transverse holes provided, respectively, in the

plates

5 and 6 near the forward ends thereof. On the shaft 20 near its ends are secured sprocke -vheel: 23 and 24, which sprocket-wheels are connected by the sprocket-

chains

21 and 22 with the

sprocket wheels

25 and 26, respectively, rotatively mounted upon a transverse tie-rod 34, the ends of which are secured, respectively, in

osts 1 and 2. A tie-rod 32 below and paral el with the shaft 20 and below the platform 19 has its ends secured, respectively, in the plates 7 and 8. A similar tie-rod 33, simiarly located relative to the tie-rod 34, has its ends secured, respectively, in the posts 1 and I 2. Rotatively mounted on the. tie-rod 32 near its end respectively aresprocket-

wheels

35 and 36. Similarly located on the rod 33 and rotatable thereon are sprocket-

wheels

37 and 38. On the tie-rod 34, adjacent, respectively, the sprocket-

wheels

25 and 26, are rotatively mounted s rocket-

wheels

30 and 31. Vertical chain be ts 39, disposed two upon each side of the platform 19, engage, respectively,

sprocket wheels

28 and 35, 29 and 36, 30 and 37, and 31 and 38. One side of each chain belt 39 isrigidly secured at'40 to the adjacent edge of the platform 19. The shaft 20 being rotated, the chain belts 39 will be driven by means of the mechanism just described-that is, the forward belts 39 will be driven by the sprocketwl1eels 28 and 29.

The rear chain bolts 39 will be driven by means of sprocket-

wheels

23, 24, 25, 26, 30, and 31, and

chain belts

21 and 22. Sprocketwheels 25 and 30 and 26 and 31 are rigidly connected together, so that when rotation is imparted to sprocket-wheel 25 sprocketwhcel 30 will also rotate. In the same manner sprocket-wheel 31 will be rotated. when the sprocket-wheel 26 is rotated. Thus when the shaft 20 is rotated in the direction indicated by the arrow shown in Fig. 1 the plat- In order that the platform 19 may be raised orlowered by hand, a crank 27 is secured to one end of the shaft 20. Rotation to the shaft 20 for the purpose of raising the table or platform 19 is obtained as follows: Near one end of the shaft 9 is mounted an eccentric 41. Pivotally mounted at one end on said eccentric is a pawl 42, the other end of which rests upon the toothed periphery of a ratchet-wheel 43, rotatively mounted on a stud 44, rigidly secured to and extending horizontally inward from the plate 6. A pawl 45, pivoted at one end to the inside of the post 4,'engages the teeth of the ratchet-wheel 43 and prevents its rearward retraction. Secured to the ratchet-wheel 43 and rotatively mounted on the stud 44 is a spur-gear wheel 46, which meshes with a spur-gear wheel 47, secured on and rotatable with'the shaft 20. ,A forwardlyextending downwardly-inclined bar 48 has its rear end pivoted on a pin 49, extending horizontally from the inner side of the plate 6 above the shaft 20. An inwardly and latorally projecting pin is mounted on the bar 48 in a position such that when the forward end of said bar is swung upward to the proper position the pawl 42 will be lifted by said pin 50, so as not to engage the teeth of the ratchet 43; but when the forward end of bar 48 swings downward to the proper position the pawl 42 will again engage the ratchetwheel 43. When pawl 42 is engaged with the ratchet-wheel 43, rotation of the shaft 9,

as denoted by the arrows in Figs. 1, 5, and 14,

the pawl 42 will be reciprocated by eccentric 4]. and step-by-st(. p rotation will thus be imparted-to the shaft 20 by means of gears 46 and 47 and ratchet-wheel 43. 'Swinging movement to the forward end of bar 48 is imparted as follows: Iivoted at their rear ends to the shaft 9 are two downwardly forwardly

inclined bars

51 and 52, which are ivoted'upon a transverse horizontal roller-s aft 58, carrying roller 53. Below and parallel with

bars

51 and 52 are

bars

54 and 55, the rear ends of which are pivoted, respectively, to the post 4 and a horizontal projeetion,56 on said post, and the forward ends of said bars 54 and 55 are pivoted to the vertical plate 57, the upper end of which is pivoted to the shaft 58. Said bars 51, 52, 54, and 55, shaft 58, and plate 57 form a swinging frame, the forward end of which moves upward and downward. In the rear side of plate 57 is provided a notch 59, in which is located the forward end of the bar 48.

As the swinging frame of which the plate 57 1s a part moves downwardly, owing to the re-' moval of sheets from the top of the pile of paper, the bar 48 Will be swung downwardly, thus permitting the pawl 42 to engage. the teeth of the ratchet-wheel 43, and the rotation of the ratchet-wheel 43 will cause the table or platform 19 to be elevated, as already described. The table in being elevated will carry with it the pile of paper and swing the outer end of the swinging frame upward, thus swinging upward the bar 48 until the pin 50, carried by said bar, raises the pawl 42 from the ratchet-wheel 43, at which time the table the forward ends ofv III elevating will cease and the table will remain stationary until suliicient sheets have been fed from the pile to again permit the pawl 42 to engage the ratchet-wheel 43.

Secured at their rear ends to the forward side of the plate 57 are two parallel horizontal forwardly-extending plates 61) and 61. A transverse horizontal plate 62 has its ends secured, respectively, to the forward ends of said plates and 61.

The swinging frame is supported at its forward end by means of two swinging

shoes

63 and 64, which rest, respectively, upon the right corner of the pile as viewed in Fig. 4, the shoe 63 being disposed adjacent the forward and the shoe 64 adjacent the right side edge of the pile of paper. The shoe 63 is mounted on and movable with a transverse horizontal rock-shaft 65, mounted in bearings 66 on the plate 62, forming a portion of the bracket. Supported at its ends in the

plates

62 and 57 is a longitudinal rotar shaft 67, connected at its rear end by a universal joint 68 with the forward end of a rotary shaft 69, disposed parallel with the plate 55 and having its rear end rotatively mounted in the outer end of a horizontal stud 70, pivotally mounted in the post'4. The inner end of said post 70 is screw-threaded and has mounted thereon a nut 76, bearing upon, the inner side of the post 4. The shoulder 71 of the stud 0 bears against the outer side of said post 4. On the stud 7.0 is rotatively eled gear 72 also meshes with a bevel-gear '7 4,

mounted on and rotatable with a vertical shaft 75, rotatively mounted in two bearings 77, secured to the outer side of the post 4 above the stud 70. Upon the upper end of the shaft 75 is secured a bevel-gear 78, which meshes with a bevel-gear? 9, mounted on and rotatable with the shaft 9. Rotation to the shaft 67 is thus imparted from the shaft9 by means of

gears

78 and 79, shaft 75, gears 72, 73, and 74, shaft 69, and universal joint 68. The. shoe 64 is mounted on the inner end of a transverse arm 80, secured near its middle to a horizontal rockshaft 81, disposed parallel with the plate 61 and mounted

bearings

82 and 83, secured to the upper side of the plate 61. The forward end of the rock-shaft 81 is provided with a longitudinal spiral groove 84, in which is dis osed the lower end of a vertical pin 85, rigid y secured in the bearing 83. The rock-shaft 81 is slidable lengthwise and when rocked, as hereincauses the shoe 64 when the shaft is properl rocked to be moved forward from the })0S1- tion shown in Fig. 10 to the position shown in Fig. 11, thus at the proper time removing the shoe 64 from a position in which it would interfere with the withdrawal from the pile of the top sheet of paper.

I will now describe the means for rockingthe shaft 81 to and fro. Referring particularly to Figs. 5, 9, 10, 11, 1.2, and 13, 86 denotes a link, the rear end of which is connected, by means of a universal joint 87, to the outer end of the arm 80, to which the shoe 64 mounted on the arm 92 and bearing upon the periphery of a cam 94, mounted on and rotatable with a transverse horizontal shaft 95-, the ends of which are respectively mounted rotatively iIIf-tWO vertical downwardly-extending plates 96 and 97, secured, respectively, to the

lates

61 and 62. The outer end of the sha t 95 hassecured to it a bevelgear 98, which meshes with a bevelear 99, secured to and rotatable ,with the s aft-67. On the pin 90 is mounted a coil-spring 100,

one end of which is secured to the said pin 90' and the other end of which bears upon the ds it in position such that the roller 93 will follow the bell-crank lever 89 and normally ho surface of'the cam 94. The cam 94 is of circular form, provided at one lace in its periphery with a recess 101. hen the shaft 95 is rotated by means of the

gears

98 and 99 and shaft 67, the cam 94 will hold the bellcrank lever 89 in a position such that the shoe 64 will rest upon the ile of paper, thus supporting the outer end of the swinging frame carrying the separating mechanism. When the cam 94 has rotated to a position such that the roller 93 will enter the recess 101, the spring 100 will swing the bell-crank lever 89 so as to raise and bring forward the shoe 64 through the intermediacy of the link 86and arm 80. When the cam 94 moves so that the roller 93 passes out of the recess 101, the shoe 64 will be again depressed so as to rest upon the pile of paper. The shoe 63 is swung as follows: On the rock-shaft 65 is secured a crank-arm 102, to the end of which is pivoted the forward end of a rearwardly-extending link 103, the rear end of which is pivoted to one end of the arm 104 of a bell-crank lever 105, pivotally mounted on a horizontal pin 106, rigidly mounted on the inner side of the plate 60. The other arm 107 of the bellcrank lever 105 has rotatively mounted in it a roller 03, which rests upon a cam 109, socured upon the shaft 95. When the shaft 95 rotates, the cam 109 will swing the bell-crank lever 105 and through the intermediacy of the link 103 and crank-arm 102 will rock the.

shaft so as to elevate the shoe 63. Rocking of the shaft 65 in the opposite direction when permitted by the cam 109 is obtained, a coil-spring 110 encircling the shaft 65, To which one end of the said spring is secured, the other end of the spring bearing upon' the plate 62.

The friction device for forcing out the sheets of paper from under the shoe 63 comprises the following mechanisinz- Referring particularly to Figs. 9, 10, 11, and 13, 111 denotes a bevel-gear rigidly secured upon. the

shaft 95 and meshing with a bevel-gear 112,

rigidly secured to the lower end of a vertical shaft 113, rotativel mounted in the plate 61 and having pivoted to its upper end one end of a bar 114, on the other end of which is secured a disk 115, provided, preferably, on its periphery with a frictional material, such as soft rubber. Secured upon the upper side of the plate 61 is a cam having a vertical circular flange 116, disposed concentrically with the shaft 113 and provided on the side ad j acent the table or platform 19 with a recess 117. The cam-flange 116 is adapted to support and elevate the bar 114, thus lifting the friction-disk 115 off from the'pile of paper excepting as at such times when the bar 114s passes into the recess 117. The bar 114 is -normally drawn downward by means of a coil-spring 118, the upper end of which is secured to the said bar and the lower end of which is secured to a horizontal pin 119, secured at one end to the shaft 113. The function of the friction-disk 115 is to rub upon and force one or more of the top sheets of the pile from under the shoe 63. The operation of this mechanism is as follows: The shaft in rotating imparts rotation to the shaft 113 by means of'the gears 111 and 112, thus swinging the bar 114 in a circular manner. Rotation of the bar 114 is in the direction indicated by the arrow adjacent thereto in Fig. 9. When the bar 114 passes into the recess 117, the friction-disk 115 will pass upon the top of the pile of paper, forcing one or more of the. top sheets from under the shoe 63. The shoe 64 at this time is in a depressed position and prevents the entire top sheet from slipping rcarwardly when acted upon by the friction-disk 115. The friction-disk 115 by its circular movement on the paper imparts movement in a similar direction to the adja cent portion of the top sheet, thus facilitating its separation from the sheets below. When the top sheet or sheets are withdrawn from under the shoe 63, they are released from the friction-disk 115 and fall back, as shown in dotted lines in Fig. 15, toward and upon the shoe 63, which shoe is then elevated in the manner already described by means of the cam 109 and intermediate mechanism to the position shown in Fig. 16, at which time the raised sheets are in position to be seized by the mechanism employed to separate the raised sheets from each other and carry the ITO top sheet to the forwardin rollers and. tapes. I will now describe the said separating mechanism: Referring particularly to Figs. 4, 5, 7, 9, 10, and 11, 120 denotes a vertical post rotatively mounted at its lower end in plate post 120 is a horizontal shaft 123, provided at one end with a right-angled crank-arm 124 and having secured at its other end a pinion 125, which meshes with an intermediate spur gear-wheel 126, rotativel y mounted on a hori zontal projection 127 on the side of the post 120. The said intermediate gear 126 also meshes with the teeth of a horizontal crown gear-wheel 128, rigidly secured to the upper side of the plate 60 and encircling and concentric with post 120. liotativel' mounted on and parallel with the horizonta portion of the crank-shaft 124 is a shaft 12.), on. one end of which is secured and rotatable therewith a friction-disk 130, the periphery of which is preferably provided with a frictional surface,

such as soft rubberi On the other end of the shaft 129 is secured a pinion 131, adapted to engage with peripheral teeth 132, provided on a circular disk 133, forming a part of the post 120 and concentric with the shaft 123. Pivoted to the crank-arm 124 is a bar 134, having secured to its outer end on the side adjacent the friction-disk 130 a frictional pad 135, preferably of soft rubber. To the other end of the bar 134 is .secured a plate 136, adapted to bear upon a cam 137, integral with the post 120, having a general circular form concentric with the shaft 123 and provided in its periphery with a notch 138. The coil-spring 13!), connected at one end to the bar 134 and at the other end to the horizontal portion of the crank-arm 124, normally swings the bar 134 in a direction such that the friction-pad 135 will be moved toward the friction-disk 130. ()n the crank-arm 124 is secured one end of a flat spring 140, the other end of which is disposed opposite and is adapted to press the sheets of paper gripped between the friction-disk 131) and the frictionpad 135 against the friction-pad 135. The flat spring 140 being of metal exerts small frictional force upon the grip-sheets of paper compared with the frictional force exerted by the rubber disk 1311 and pad 135. The total of the frictional force exerted upon the gripped sheets on the sides adjacent the disk 131) and spring 140 will therefore be less than the total frictional force exerted by the friction-pad 135. When the friction-disk 130=is rotated at a time whcnthere are two or more sheets held upon the pad 135 by the spring 140 and disk 130, all the sheets exce t the sheet next to the pad 135 will be ejecte but the sheet in contact with the pad 135 will be retained, the frictional force tending to retain the sheet preponderating over the frictional action of the disk 130. So when more than one sheet is gripped between the disk 130 and pad 135 all except the top sheet will be thrown back upon the pile; but the top sheet will be held notwithstanding the retary movement of the disk 130 and will be carried by the said disk and the pad 135 to the forwarding rollers and tapes, hereinafter described. When the shaft 67 is rotated, thus rotatin the post 120 by means of the gears 121 an 122, the shaft 123 and crank-arm 124, together with the shaft 129 and bar 134, will be caused to describe a circle with the axis of the post 120 as a center, thus carrying the friction-disk 130 and pad 135 over the corner of the pile of paper adjacent the shoe 63. At the same time rotation to said crank-arm 124, shaft 129, bar 134, and parts connected therewith will be obtained around the axis of the shaft 123. The arrangement of the parts are such that when the crank-arm 124 is in the position shown in Fig. 10 the relative positions of the disk 130 and pad 135 will be that shown in Fig. 16, the disk and pad being separated so as to admit between them the raised sheets, the'ilisk 130 being upon the under and the pad 135 upon the upper sides of said raised sheets. At about this time, the post 120 being rotated in the direction indicated by the arrow in Fig. 10, the plate 136 will enter the recess 138 in the cam 137, (shown in Fig. 8,) thus permitting spring 139 to press the pad 135, sprin 140, and disk 130 tightly against the raise sheets. At the same time the inion 131 will engage the teeth 132 on the dis 133, and rotation will thus be imparted to shaft I 129 and disk 1'30. Engagement of the pinion 131 with the teeth 132 is due to the rotation of the shaft 123, which is driven by means of pinions 125, gear 126, and crowngear 128. At about the time that disk 130 begins to rotate, earn 109 on the shaft 95 will, through the intermediate mechanism already described, swing the shoe 63 to the vertical position, as shown in Fig. 17. Continued rotation of the disk 130 will force out from between said disk and the pad 135 all the raised sheets excepting the top one, the

other sheets falling back upon the pile. The shoe 63 then descends, earn 109 permitting, to the horizontal position upon the pile of paper, thus supporting the swinging frame and the IIIGChlUIlHII'l carried thereby. Continued rotation of the ost 120 will through the mechanism herein efore described continue the rotation of the shaft 123 with the crank-arm 124 and parts carried by said crank-arm until the pad 135 and the disk 130 will have been swung to the position shown permitting the said in Figs. 11 and 18, the disk 130 at this time being above the pad 135. In this position the top sheet of paper, as shown in Fig. 18,

will be brought in position to be inserted bea tween and grasped by the forwarding-

rollers

141 and 53, respectively. At this time the crank-arm 124 will have been swnug to a position such that the pinion 131 will pass out of the teeth 132,when the shaft 129 and disk 130 will cease to rotate. At the same time the plate 136 will pass out of the recess 13S onto the circular periphery of the cam 137, thus swinging the bar 134 so that the pad 135 will move away from the spring 140 and disk 130. The top sheet of paper will thus be released, so that it can be removed freely from the ile of paper by the

rollers

141 and 53. At vt 1e same time theshaft 95 will have been so rotated that the roller 93 of the bell-v crank lever 89 will enter the recess 101 of the cam 94. The spring 100 will then swing the bell-crank lever 89 so as to depress the outer end of. the arm 80 by means of the link 86 and universaljoint 87. The rock-shaft 81 will thus be rocked and at the same time slidforward in the

bearings

82 and 83 by means of the pin 85 and spiral groove 84. The shoe 64 will thus be raised and moved forward to the position'shown in Figs. 11 and 18, thus clearing the said shoe from the top sheet and shoe to, again pass back upon the top of the pile of paper below said top sheet.' Continued rotation of the post 120 and parts connected therewith will again bring the parts to the position shown in Fig. 10, at which time one or more sheets. of paper will have again been rubbed up from the pile by means of the friction-disk and deposited upon the snoe 63, which will have once more been lifted to the position shown in Fig. 16, the cam 101) so permitting, at which time the raised sheets will be seized between the disk 130 and the pad 135, and the o )eration of separating the raised sheets wifl be repeated. .The arrangement of the several )arts is such that the different steps hereinl efore described will take lace in their properconsecutive order. I or every rotation of the shaft 113, carrying the bar 114, having thereon, the disk'115, the post will also'nmkc one 1'Otzltl()1l,lt11(l the shoes (53 and 6-4 will be raised and lowered once each. The lorinof the cams 94am! 101) and their position upon the shaft 115 are such that one of the shoes (33 or (H. always rests upon the )ile of paper, insuring the supporting of the forward end of the swinging frame carrying the paper rubbing and separating mechanism.

A transverse horizontal shaft 1-13 is rotativclymountcd at its cnds above the roller 11 in the posts 3 and 1. ()u said shaft 14; is

mounted and rotatable therewith a roller 1.13.

Endless tapes 1-14conncct said roller 113 with rollersor disks l41,mountcd onandrotatable l the lllt'lllill lmll 1135 with a transverse horizontal shaft 145, the ends of which are rotatively mounted, respectively, in the forward ends of two forwardly

inclined bars

146 and 147, the rear ends of which are pivoted on the shaft 142. The rollers 141 rest upon the roller 53, by which the rollers 141 and tapes 144 are driven. The functionoftapes 144 and rollers 14 I and 143 is to prevent the sheets from being raised from the endless tapes 148, mounted on the rollers 11 and 53, which tapes 143 are the carryingtapes which carry the separated sheets from the sheet-separating mechanism hereinbefore described and deliver them upon the registering cord or tape 12. The forward ends-of the

bars

146 and 147 have secured, respectively, to them the rear ends of two

forwardlyextending bars

149 and 150, in the forward ends of which is rotatively mounted a transverse shaft 151, having secured thereon two grooved wheels 152, connected by endless tapes 153 with grooved wheels 154, secured upon the shaft 1.45. The function of tapes 153 is to properly guide the top separated sheet between the

rollers

53 and 141.

The 'eneral operation of my invention is as follows: The paper to be fed and registered is placed in a pile table or platform 19 and disposed so that the shoe 63 rests noon the top of the pile adjacent the right orwa'rd corner of the pile, as

viewed in Figs. 3 and 4, and the shoe 64 resting upon the top ofthe pile near the right side thereof and to the rear of shoe 63. R0- tation is then im )arted to the pulley 15, thus rotating the shaft 14 and roller 13 and driving the. cord or tape 12 in the direction denoted by the arrows in Fig. 3, so as to carry the sheets deposited on the cord 12 toward the roller 13, the rotation of the cord 12 carrying the sheets sidcwise to the guide. projections 17. tated, thus rotating, through the mechanism already described, the shafts 0t), 67, and U5.

The roller 11 is driven by the cord 1'. and

in turn imparts movement to the roller 53 by means of tapes 148. The tapes 144 are driven by rollers 141, rotated by means of roller 53. The same l'ollcr rotates wheels 154, thus driving the belts or tapes 1533. Hotat ion of the shaft (57 is imparted to the shaft 1131)) means of the mechanism descrilwd, and the bar 14 is thus swung in a circle upon the cam 116. The friction-disk 115 when the bar 114 enters the notch or recess [17 passes down upon the pile of paper and rubs out one or more of the top sheets from under the shoe 63, which sheets as the disk 1 I5 is again raised by the cam 1'10 fall back upon the shoe tiii, b which shoe they are lifted to the position shown in Fig. it), the shoe till being raised by means of the mechanism connecting it with shaft (17. hcrcinbcforc described. Thc raised heets are now seized by and the friction-disk (denoted by 18) on the.

'At the same time pulley 10 is roand are carried toward the forwarding *or carrying

rollers

141 and 53, the said friction pad and disk being rotated by means of the mechanism already described. During the forward movement of the raised sheetsall but the top sheet are thrown back upon the pile by means of the rotation of the disk 130, the top sheet being held between the disk 130 and the pad 135 until the sheet is seized between the

rollers

53 and 141, at which time the disk 130 and pad 135 are caused to separate, as already described, and thus releas 'ing from them the top sheet, which is now stripped from the pile with its sides reversed and is carried on the tapes 148 to and between the rollers 11 and 143 and upon the registering cord or tape 12. As the sheets are fed from the table 19 the swinging frame carrying the

shoes

63 and 64 lowers until the frame carries the outer end of the bar-48 down suflicientl for the pawl 42 to engage the ratchet-wlieel 43, thus eausing, as described, the table-elevating mechanism to raise the table, which upward movement continues until the bar 48 strikes, through its pin 50, the pawl 42 and raises the said pawl from engagement with the ratchet-wheel 43. Thus as the sheets are fed from the pile the table is intermittently raised corresponding with the swin ing of the swinging frame su porting the s 1eetseparating mechanism; he shoe 64, while serving to support'the swinging frame when the shoe 63 is lifted, also serves to hold the top sheets from slipping when the disk 115 is rubbing the top sheet or sheets rearwardly, as shown in Fig. 15. The flat spring 140 serves to hold the raised sheets against the pad 135 while the disk 130 is being rotated against the raised sheets. The rotation of the rank 124 with the shaft 123 enables the disk 130 and pad 135 to grasp the top sheet and reverse the sides of the said sheet while carryingit to and delivering it between the rollcrs 53-a11d 141.

Any other sheet-registering mechanism than the one shown may be employed with my sheet-separating mechanism.
