Referring vto vFig. l, the side frames 1.3

ico

` and 14 support the standards 15x-and 16 ire-lv .y

spectively whiehfcarry the operative parts of my sheet-registering mechanism. EX- tending acrossfthe machine is the reciprocat- `ing hollow im .i7 Siifiabiy annalisa in the collars 18 and 1.9 mounted on the standards and16 respectively. The sheet-registering' devices are adjustably supported on thev supporting bracket 20 has the split jaws 21 and 22 formed in its upper portion to en circlev the bar 17 as shownin Fig. 8, and

these split jaws are drawn together to hold y the bracket in any iXed position on thebar 'with' the fixed clamping plate 25.

17 bythe screw bolt 2,8. When thebolt23 is unscrewed the jaws 21 and 22 slide transversely on the bar 17 to eiect the required lateral adjustment. Y

Referring to Figs. 1, 2 and 8, the bracket 21E-has the depending arm 24, the lower end ot which carries the horizontally disposed plate 25 which forms the fixed lower inemher ot the sheet-clamping devices, the advancing sheet sliding over this plate to strike the front guides (not shown); Journalled in the arm 24 above the clamping plate 25 is the small. stub-shaft 26 which carries the rock-arm 27 which is normally forced downwardly into contact with the plate 25 by thecoil-spring 28, the tension oi' which is regulated by the collar 29 as shown in Fig. 8. Pivoted on thel free end ofrockarin 27 is the rock-pin 30 (shown in Figs.

4 and 7 which'carries the rocking clamp shoe 31, this shoe being designed to have f contact with the upper surfaces of the sheets and to seize and clamp same in conjunction The spring coiled about the pin 30 and connected with the outer collar 33 and the sleeve 84 on which the clamp shoe 31 is mounted, yieldingly maintainsthe heel 35 of the shoe 31 in continuous contact vwith the clamping plate as shown in Fig. 2. The oppositelyextending lugs 3G and 37 are preferably integrally ilornied on the 'free end of the rockai'm 27, as shown in Fig. 4, to limit the rocking movements of the shoe 3l on the pin SOVwith respect to the plate 25.

` Between the two side 'trames 13 and 14 are arranged tw-o mutually parallel cross-bars 38 and 39 as shown in Figs. 4, 6 and 7. Slidably mounted upon the bar 39 is the adjustable bracket 40 which is preferably secured to the bar 89 by topfplate 41 and the screws 42. A screw-threaded bore 43 is drilled in the side of the bracket l40 as shown in Figs. 4 and 5 which bore is engaged by the screw bolt 44 the point of which engages with the bar 39 to hold the bracket 40 in fixed position after the required adjustment. Also vslidably mounted on the bar A39 and inside the bracket 40 as shown in Figs.y 1,A 2 and 4, is the Aadjustable guide block 45 having the horizontal channel 4G formed in its top surtace through which the plate 25 is adapted the sheet-seizing 'devices heretofore 1,43e,ecfi

to travel. laterally when the bar 1 7 which supports the sheet-registering devices is reciprocated as will be hereinafter described. @n either side ot the channel 46 are the side-gages 47 and 48 against which the sheet is drawn for side-registry. Below the side 48 and extending laterally Yfrom the block 45 and suitably secured thereto as shown in Fig; 6 is the bracket 49 having the screw-threaded bore 50 formed transversely therein as shown in Fig. 4. This bore 50 is engaged by the threaded bolt 51 which passes through the threaded lug 52 mounted on the bracket 40 which lug alsov carries the threaded bolt 44. The thumb- screws 58 and 54 are secured to the bolt 51 to turn same to kmake the relative lateral adjustments on the bar 39 between the bracket 40 and block 45 as will be readily understood. Mounted on 'the block 45 and extendingforwardly over the bar 38 as shown in Figs. 4 6 'is the side guide plate 55 under which the sheet 56 is advanced before being side-registered. The vertical position of the plate 55 may be regulated by the screw 57 and the downwardly bent cross-plate 58 mounted on the block 45 as shown in Figs. G and 7 enables the sheet 56 to pass readily over the bar 38 onto the top surface o't the block 45 under the impulse of the sheet-'forwardingl mechanisms. y

llde'ans are provided to transversely reciprocate the cross-bar 17in timed relation. with the advancing `ot thesuccessive sheets in suitable position to be side-registered by described. ln the embodiment shown particularly in Figs. 1 and 11, the rightend of' the Ibvar 17 carries the collarI 59 having the depending pin 60 upon which the link 61 is journalled; the other end of the link 61 is pivotally connected to the outer end oi the rock-arm 63 mounted on the top of the vcrtical rock-sleeve (34 journalled on the upright shaft 65 carried by the bracket 6G suitably atlixed to the side traine 14. The .lower end oi" the sleeve G4 carries the horizontally disposed rock-arm 67, the upper end o1: whichis pivot-ally connected tothe rocklever 68 by the'link 69. The rock-lever G8 is journalled to the stub-shaft 7 0 secured to the trame 14, and the lower arm 71 ot the rock-lever 68 carries the cam-roller 72 which I is maintained in engagenient'with the` cam 7 3 mounted on the main power-shaft 74 by the spring pressed rod 75 pivoted at 76 to the arm 71. and also suitably conneotedby the sleeve. 77 pinned to the side-iframe 14.

Reterring'to Fig. 11, I have shown diagrammatically a forni of mechanism where- 'carried one by. one fromthese feed-rollersforwardly to lthe sheet-registrydevices by' the tapes 91 passing around-the feed roller y :rod :87, the lower end of-which is slotted aboutzthe.. shaft 74. 'Therod 87 carries the cam-roller 88 in engagement with the cam 89secured to-l theshaft'74, wherebyV the rod 87 is reciprocatedonce during each 'revolution of the shaft 74 to :bring the feed-rollers 81 and82 in operative conta'otwith' 'the sheet to be advanced. The sheets are fed to the yfeed-rollers81.and-'82 from a pile' (not. shown) onv the feed-board 90, .andr are 81. and the tape roller 192 as shown. in Fig. 11.

The meansk for operating the sheet-clamping devices and in drawing the sheetlaterally to effectk the 'proper side-registry against the side-gages is directly operated by the lateral reciprocations of the crosskbar 17 as justdescribed. The mechanisms to accomplish this Aside-registry are best shown in thek different parts of their cycle of movements in Figs. -1, 2 and 3 while the structural details-are also .shownin an enlarged scale in Figs. 8, 9 and 10.

Referring morefparticularly to Figs. 1,

2, 3 and-9, the left endk of thebar 17 carries the collar 93-secured tothe end of the bar 17 by the pin94 The collar 93 carries the diagonallydisposed support 95, the angular -positionfof which may be adjusted on the bar 17.by.'the screw-pin 96.

Resting on the support 9.5.is the triangular- Shaped.oam-plate'97fpivoted at its apex on .the screw-pin 96 as fshown in Fig. 9; the

lower lend ofthe p1ateX97` carries the camroller 98 which is adapted to engagey the cam-face 99 formed in .the bracket 100 which is adjustably secured tothe outer end rock-shaft 101 by the screw 102. This rockshaft 101 is journalled on its'outer end in the support as shown in Figs 1, 2 and 3. Formed in the cam-plate 97 is the curved slot 103 through which passes the thumb screw 104 to `guide and maintain the .plate 97 in proper position resting against the vinclined face of the support 95. rlhe rockshaftlOl extends inwardly and'atransversely of the machine with its inner end j ournalled in the block 105 secured'to the-bracket 20 through the varm 106 as shown in Figs. 8 and 10; adjacent the'block l'105 is the rock- -sleeve 107 adjustably secured to the rockyshaft 101 by the-key 108 as shown in Fig.

12. Preferably integrally formed on the sleeve 107 is the lip 109 which engages with its upper surface the roller 110 pivoted on the lug v111 kextending upwardly from the rock-arm. '27 whichiroller 110 is. norm ally in contactfwith the lip 109 `by thespring 28 as-shown in'Figs. 8 and-10.

The 'cam-roller 98 is caused to ride up i and down over `the cam-face 99 tocause the rock-shaft 101 `to oscillate to raise the clamp-shoe 31 when the cross-bar 17 is laterally reciprocated by devices best/shown in 'Figs 1, 2 and 3. The standard 15 carries `the bracket 112 which supports the adjustable screw bolt 113- extending. laterally I therefrom,and the standard 15 also hassecured to it the horizontally disposedL rod 114 screw-threaded'at its outer end 115-on which the buffer lplate 116 is adjustably 'mounted by nuts 117. vThe head of the bolt .113 is adapted to contact with the right shoulder of the cam-plate97v when the crossbar 17y is reciproca-ted to the right as shown in Fig. 8, to push the cam-plate to f 101 immediately to rotate in the direction of the arrow coiled about the shaft 101. Such oscillation of the shaft 101 lifts the clamp shoe '81 to release the Sheetalreadyl side-registered against the side-gage 48, the heel remaining incontact with the plate y25 beyond the side-gage and out of the zone kof the sheets through the tension of ythe s ring 32. The relative "distance betweenk kthe screw-bolt 113 .and buffer-plate 116 may be regulated to yadjust the duration ofthe action of the clamping membersv onthe sheet during the left movement of the cross-bar 17 to meet the requirements as to the thickness and kcharacter of the sheets; 'F ig. 2

shows the action of the parts by which the clamp shoe 31 is positively raised out of ycontact Vwith the sheet 56 after it has been drawn against the side-gages 47 and 48 as shown in Figs. 1 and 2. The operation ofmy sheet-register in conjunction with the sheet kforwarding mechanisms shown in Fig. 11 is substantially as follows: `When the cam-rollerI 88 isl travelling on the high part of the cam 89 the upper feed- -rollerisraised and a sheet advanced by the feed-rollers from the pile in the table 90 has been forwarded by the tapes 91v against the ifront guides andthe side-registry devicesare operative.v The cam-roller 72 is shown in the drop of the cani 78 which indicatesthat the bar 17 has completed its registering stroke to the left 2) and is about to be reciprocated to the right tov be shifted into the #proper position at the beginning of the iso tapes against the front guides (not shown) the sheet clamping devicesproper (plate i gravity) on the side margin of the advance-d :and clamping shoe 8l) aremoved to the right as a unit with the clamp shoe 31 raised as in Fig. 2 due to the tac-t that thecamrollery 98 rests on the high part of the camace 99 and hence has oscillated the rock- `shaft 101 so as to raise the. clamp shoe 31 against the tension of the spring 98 when the shoe is maintained and raised as 1n Fig.

2. llilhen the right shoulder of the camel plate 97 strikes the screw-bolt 113, the camplate 97 is swung oil' centreto the left which causes `the roller 98 to run down' the camace 99 thereby releasing the clamp shoe y31 which is snapped downwardly (assisted by sheet resting on the clamping-plate 25. T he left movement of the har 17 as shown in Fig.

1 in the direction of the 4arrow carries the sheet-clamping unit with the sheetA 56 into side-registry with the side-g'agzges a7 and 48,

i and a turther movement of the bar 17 to its extreme lett position shown in Fig. 2 carries the lett shoulder ot' the lcam-plate 97 against ythe butter-plate 116 thereby causing the camplate 97 to swingto the right as shown in Fig. 2 which swinging movement carries the cam-roller 98 up on the high part of the camface 99 and depresses the latter and so rocks the shaft 101 as to lift the clamp shoe 31 i plished by the screw-bolt 23 while the coinplementary adjustments oi the lug 105V and sleeve 107 on the rock-shaft can be made by shitting the key 108 transversely on the sha'lt 191. ln like manner a delicate adjust ment oi the side gages with the'normal line of the side edges ofthe successive sheets can be made in either direction by actuating the screws 53 and 54. I have already explained that the relative distances between the head or the screw-bolt 118 and the buffer plate 116 may be increased or diminished byadjusting either bolt or plate, which distance will directly affect the action of the clamp shoe 31 in seizing and releasing the sheets; this feature is of advantage in properly side-registering sheets ot different character and thickness.

lVhile the construction set forth herein embodies the invention in its preferred form, many changes and variations may be made 1,439,eoa

therein without departing iifrom the underlying principles and advantages disclosed therein; and it is to be understood that while these improvements are particularly adapted tor use in connection with sheet-feeding machines they may be employed in other relations. `While the preferred rsel of my improved sheet-register is ior side-registering the sheets as shown and described, it is manifest that my improvement may valso be employed for frontregistering the sheets bciore being advanced to a printing'or other like machine. v
