To atl fio/ioni it may conce/ut. j

Be it known thnt I, HARRY M. SALYER, e citizen oit the United States, and resident of \lewe.rl';, in the county of Esser: .find State of New Jersey, have invented certain new end useful iiiprovenients in Perforeting Apps rfi-tus, oi' which the 'following is n specii'ice.- tion.

The object of mv invention is to provide en l apparatus wherein one sheet, or e pluralityT of sheets simultaneously, niey be perforated, the

operetioiiof perforziting snch sheets'beingl controlled automatically by e inester sheet or l l creased or diminished in dii'iiension and spec- 25 ing es required.-

A further object'of the invention is to provide in seid apparatus ineens for ieprodncf.

'ing iiuisteil or pattern Sheets from an originel li'i'iiister, ,or pattern sheet, 'es'. distinguished from reproducing stock perforated sheets.

A 'further object of the invention-'is lto per-'- init the winding of the .perforated sheets upon: their respective reels directly-as. the perfo-g 5 rations lere inside in the sheets,'in sueh man1 ner ,that the vperforated sheets berea'd'yf vfor use Idirectly in the :ippropriate.. rinusicfel instrument without the necessity'ofrewin ding the' previously `perforated lsheetsi'lpori the music rolls, as has heretofore been `cus- 'tomaryso-fer es I 'am aware'. To this end I pass the master perforatedY sheet or pattern. ncro'ssthe vbridge of the zippsretusin:there` Vverse direction of rendering of thefmusicel composition, 'as by passing the master sheety backward vthrough the apparatus'. lso that the sheets to belperioraltedwill be perforated..

i'eversely tothe proper'notation of the Inusicel composition, les vfrein `the vending of the` composition to its beginning, and such re- .versely perforated sheets are wound directly l upon the music roll spools as the perforeting is accomplished so th'etwlien the completely perforated sheet'is fully wound on its spool the commencement of the musical eoiiiposi-` pattern, whereby the perii'iriitions previously v stock. sheets upon their respective inusic tion therein perforated will be the outer end of the music roll ready lor use iii usuel manner.

Similar characters of reference' indicate Acorresponding parts in the several views.

ln the accompanying drawings, the numeral 1 indicates a suitable fraine, and at 2 is a suitable bridge or tracker which is provided With a series of orifices 2a, shown arranged in a straight line, and across which the master music sheet lor pattern 3 passes. Said master sheet is supported upon a suitable reel t shown carried upon brackets 5 of frame 1; any suitable means being provided to permit ready insertion of the master reel in and removal from its supports.

The shaft 6 for reel 4 is provided with a sprocket Wheel 7 receiving a chain 8 that passes over a sprocket 9 connected With a friction pulley 10 supported upon an arm 11 pivotally carried by frame 1, for rewinding the master sheet When required, as hereinafter explained. The master sheet passes from its reel i under a guide roll 12 and from thence over bridge 2 to the controlling drurn or roll 13. Roll 12 may be detachably supported in frame 1 to permit the vready placing of master sheet 3 thereunder. Bridge 2 is mounted to have lengthwise adjustment in frame 1 to cause the orifices 2a to be adjusted transversely of the master sheet to accord with the perforations in such sheets, and for this purpose l have shown a screw-threaded rod 14 secured to bridge 2 by a pin 14h and passing freely through a hole in frame 1 and having a nut la@ bearing against said frame, an expanding spring 15 being interposed between said bridge and frame 1 tending to push the bridge (see Figs. 3 and 7), the pin 16 at the opposite end of bridge 2 being journaled to slide in a suitable hole in frame 1, said pin having a collar 16"L provided with a pin 16b sliding in a hole in frame 1 to prevent the bridge from turning. By turning nut 14a to theright or left, bridge 2 may be adjusted across frame 1 the desired distance respecting the` perforations of the master sheet. The master sheet drum 13 is secured Yto shaft 17 journaled in suitable bearings in frame 1, and said drum is rnade longitudinally expansible to vary the distance between its circular rows of pins 13a to cause them to fit the rows of holes 3a near the edges of the master vsheet that may vary in the distance between them, and for this purpose l make drum 13 in tivo parts 13', 13"-, the part 13b being secured to shaft 17 and telescoping with part 13, the latter part having lfree movement along shaft 17, pin 1? on one part entering the slot 20 in the other part to cause rotation of part 13C' by and with part 13b While permitting endwise relative adjustment of said parts. Shaft 17 is provided with tln' ls 1?'a receiving a nut 21 which engages a hub 13l on part 13c and supports the adjacent end thereof, a spiral spring 22 Within part 13C bearing againstY the latter and against part 13b tending to sepa. rate said parts. By rotating nut 21 the rows of pins 13a lof roll 13 may be caused to approach or recede as required to cause said pins to properly enter the holes 3a of master sheet 3, (see Fig. 12). The diameters of the parts 13b, 13'C are substantially equal so that the Working surface of roll 13 shall be substantially uniform.

Shaft 17 is to be rotated step by stepto correspondingly advance sheet 3, and for this purpose l have shown a ratchet Wheel 22 secured upon shaft 17 and engaged by the spring pressed pawl 23 carried by a rock arin 24 pivotally supported concentric With or upon shaft 17 and connected by a link 25 With a crank pin 26 on a shaft 27, suitably journaled on frame 1 and provided With a loose pulley 23 and a clutch, whereby as shaft 27 rotates, dog 23 and ratchet 22 Will cause shaft 17 and drum 13 to .rotate step by step to correspondingly advance master music sheet 3.

To provide-the proper amount of slack in master sheet 3 between the orifices of bridge 2 and the pins 13a, to cause said pins to properly register with the orifices of the bridge, provide an adjustable bar or the like 29, pivotally supported .upon frame'l and extending over sheet 3 between bridge 2 and drum 13, said bar being eccentrically disposed and preferably removably supported to permit the ready insertion thereunder of sheet 3. The pintle 2Qa of bar 29 is supported in the bearing 30 of frame 1, and

the opposite end 29b of said bar is inserted in a socket in a short shaft 31 journaled on frame 1, (see Fig. 3), and provided with a handle 31 l for turning bar 29, which shaft 31 may be held in set position by a nut 32. By suitably turning bar 29 the length of sheet 3 between orifices 2a of the bridge and pins 13*rt of drum 13 may be increased or decreased as required to cause proper ,v tracking of the master sheet across the orices of the bridge.

After master` sheet 3 passes from drum 13 it is lWound on a reel 33 shown supported on uprights 311 of frame 1, and 'said sheet is shown passing under a detachable idle rolll 35, suitably supported in frame 1, to cause purpose I have shown arm 24a (which .ex-

tends from arm 24) pivotally connected by a link 36 with a rock arm 37 hung upon a shaft 38 journaled in suitable supports on frame 1,

a ratchet wheel 39 secured on shaft 38 being engaged by a spring pressed dog 40 carried by'arm 37, whereby shalt 38 is rotated step by step coincident-ly with drum 13. Shaft 38 also carries a pulley 41 receiving abelt 42 that passes over a pulley 43 on the shaft ol takeup reel 33 whereby the latter is rotated, and the arrangements are such that belt42 -will slip on pulley 43 when necessary to prop# erly wind sheet 3 on reel 33 as the diameter of the sheet thereon increases.

. through chain 8, and to this end I journal a shaft 44 in traine 1 and to an eccentric pin 45 on said shaft I connect a link 46 with arm 11,

(see Figs. 3 and 4), and I provide shaft 44 witha crank or handle 47 for rocking the same as desired. By turning shaft 44 to cause frame 11 to swing 'pulley 10 against pulley 28 the master sheet may be rewound onits roll as muchas desired at any time, but normally pulley 10 will beheld o ut orp engagement 'with pulley 28. When sheet 3 is rewound belt 42 may be slipped ofi' its pulley andthe sheet .disengaged from parts 12, 29, 13and35.l

To cause thestock sheets 48 to be'perforated in'accorda'nce with the perfora'tions master lsheet 3,1 provide the following arrangement: .At 49 arel afseries of punches arranged a `straight line across the -machine and llocated in suitable holes in a guide 50 extending acros'sframe 1 abovea die51 that is provided; with -holes 51a to receive punches '.50y and die 51 for the passage of the stock sheets 48, (Fi s. 5 and 11). Thepunches'49 are controlle by areciprocative'head 53 that is guided at its ends in suitableguides 54 on frame-1 and' said head is pivotally connected by a link 55 with an eccentric or cra-nk 56 on shaft 27.A Head 53 is shown lproe vided lwitha flange` 53?.having holes 53 reeiving punches" 49,-. and said punches are provided with ins or'projections 57 adapted o rest upon anoe 53a, whereby the latter may-liftsaid punclh s from' die 51;; The projections57 are shown guided in vertical- I grooves 58a in a bar 58 shown secured on i; guide 50, whereby punches '49 are kept tron rotating, 'and a plate 59 secured over grooves 58a by engaging projections 57 limit the upward movement of the punches when -lifted .Y byhead 53.

65 To cause 'punches 49 to punch holes in the To rewind sheet 3 upon its reel 4, whende- 49, a space'52 being provided betweenguidef sheets 48 as required in accordance with the perforations of master sheetV 3, l provide slides 60 carried by head 53 and which are normally retracted from over the punches, and are pushed forwardly over the punches by devices connected with pneumatics that are'controlled by the master sheet vpassing over bridge 2. The slides 60 are guided in suitable ways or grooves 61 provided in head 53 which vmay 'be formed between lugs 61'i1 formed on the corresponding partsof head- 53 (Figs. 1() and 11), and said slides are Lshown pivot-ally connected with rods 62 which are' pivotally connected with levers 63 pivotally supported by cross bars' 64 supported upon frame 1. Said cross bars 64 are provided with pneumatics fort operating levers 63, shown enlarged in Figs. 15 and 16, The pneiiuiatics, illustrated are formed by providing the bars 64with a suitable number of chambers or pockets 65 in one face and placing over` their open ends diaphragm 66 of suitable flexible material, such as leather, rubber cloth, or the like, and to each diaphragm in line with the corresponding chamber 65 is connected the corresponding lever 63, as by means-of a stud 67 having a threaded portion passingtlnough the dia phragai and held by a nut 68, a washeror flange 69 on the opposite side of the diaphragm in conjunction with nut 68 serving to make air tight joints at the diaphragm.. The levers 63 are pivot-ally connected with the'corresponding studs 67 by pins 70, and springs 71 acting with said levers serve to draw the diaphragnis outwardly and thereby move levers 63 to cause them to push rods 62 to move the corresponding slides 6() over the associate punches 49. 'l have shown springs -71 as coiled around the ivots 72 ol levers 63 and having one end bearing' against pin 7() and the other end' against bar 64.

The diaphragms 66 may be made by along stripof flexible material pasted on-the face offbar 64 to close all the'chambers 65 air sembling of studs 67 of the pneumatics upon the diaphragm or diaphragme I have shown the rearwalls ot'charnbers 65 as provided with openings 65a through whichthe correspending nuts 68niay be manipulated, and

to the outer face ol bar .64I paste suitable material, such as leather, rubber cloth, or the like 73 to lclose the openings 65a, providing air 'tight pneumatic chambers. Chambers" 65 are 'connected with corresponding orifices of bridge 2, and to this end the passage 65b of each pneumatic chamber 65 in the bars 64 is connected, as by rubber tubes 74, with the l b f h l` 2a t ocres 2. `o tv o correspon( ing orinces o the bridge. The bridge is provided with a longitudinally disposed suction-chamberl .2 that communicates through ports 2d with 1-10 tight, although separate d1apnrag1ns for one or more pneumatic chambers 65 may be prolvided if preierredvIn order to permit asthe corresponding bores 2b of the bridge. The chamber 2C is connected by a suitable tui e 2e with any suitable air suction pump (not shown) for maintaining suction in chainber 21l Each port 2d is adapted .to be controlled as required by the tapei'ed end 75 of a screw 75L meshing iii-a threaded hole in bridge 2 (see F 14) for regulating the flow of air from bores 2l into suction chamber 2c to permit the proper amount of air to enter the corresponding pneumatic While still periiiitting the proper fion.' of air from the pneuinatic to the suction chamber 2C. TvVhen a perforation in the master sheet passes over an orice in bridge 2 air passes through the corresponding bore 2b and tube 74 into the associate pneumatic chamber 65 relieving the suction therein, and the corresponding spring 71 operates lever 63 to push the corresponding slide 60 over the associate punch 49, and thereby as hea-d 53 continuously reciprocates such punch will be caused to punch a hole in the stoclr sheet or sheets 48 corresponding to the perforation in the master sheet then over the corresponding orifice, Vand so on for the various pneuinatics in accordance with the perforations of the master sheet passing over the orifices of the bridge. When the. master sheet next closes 'said orifice in the bridge the air from the ,corresponding pneumatic is sucked into chamber 2C of the bridge, and then the corresponding diaphragm 66 pulls back against spring 71, overcoming the same, and thereby lever 63 pulls the corresponding slide 60 from over its punch, all whereby when the imperforated part of the master sheet is over the orifices of the bridge the corresponding slides will be held retracted :from over their punches, and whereby when the master sheet l aline with orifices of the bridge the corresponding slides 60 will be pushed over their punches to the perforations of Vcause the stock sheets 48 to be correspondingly punched in accor-:lance with the per-I frations of the master sheet.

Vivhile I' have above described a convenient form of pneumatics for operating slides 60, it Will be understood that the saine may be altered to accomplish the saine results, and

.to this end in Figs.A 17 and 18 I have shown a modification of the pneumatics as follows: The studs 67 are secured air tight to diaphragm 73 and the heads of said studs bear against diaphragm 66 and lie within chamber 65, and over each diapliragm 6 6 is a chamber 76 communicating by a tube 74 with thc corresponding borc 2b of the bridge. A suction chamber 64a in har 64, (having a suction pipe 64b connected to the suction pump connected With chamber 2) is provided with ports 64C leading to chambers 65 for permanently maintaining suction vin. said chambers 65. The relative positions of diaphragmeI 66 and 73 when the orifices in bridge 2 are closed by sheet 3 is such as normally to hold levers 63 l i l vhunting the thrust of grippers in position to retract slides-60 from their punches and the suction thus maintained in chambers 76 through tubes 74 from chambr 2c of the bridge,I raieiics the air in chambers.

76 to the same degree as maintained in chain- 70 bers 65 permitting diaphragm 73' to rock levers 63 to pull the slides 60froni the punches, and when an orifice of the bridge is opened by ahole in sheet 3 air enters the corresponding chamber 76`Whereby'suction 75 in chamber 65 pulls diaphragm .66', which.

being of greater area than diaphragm 73 pushes stud 67fcausing it 'tooperate lever 63 to push its slide 60 over its'punch 49.

Pulley 28 is mounted looselyupon shaft 27 30 and any suitable clutch may be provided to rotatively connect said pulley and .shaft, which clutch may be thrown into and out of action by a lever 80 pivotally supportedupon frame 1 and havin a slide bar 81 to controlvg5 the clutch, adaptedto cause shaft 27 tostop in such positionsthat head 53 will b e elevated to hold punches 49 above sheets48; and fa brake 82 checks themoinentum of shaft'27 (Fig. 4) in manner similar tol'clutchesin die 90 presses.

The stock sheet or `sheets 48 to be 'perforated are drawn between guide 50 and die 51 step by step as required, and in order to positively and uniformly draiv the punches 49 may accurately and corre-` spondingly punch such sheets simultaneously l provide the following arrangement.:

at 85, 86 are shafts' journaled in frame .1 and 100 Wheels 87,88 respectively carrying sprocket near opposite ends, over which Wheels chains 89 pass and to said chains are attached cross bars 90 at suitable distances apart, the-ends of which bars travel in guide groovcs91A in 105 bers or plungers 95 (Figs. 19 and 20) which 115 are shown provided with stems 96 supported in bearings in levers 93 and engaged by corresponding springs 97 interposed between the grippers and guides 93 for normally press-- in the grippers 9 5.by springs 97. The outer arms 9S are adapted to en' vgage the inner faces 92"t of guide 92 to cause the gripper levers 9? to rock and press the grippers 95 firmly upon sheetsv 48 (iii the po- 125, sition shown in Fig. 20), andv said gripper levers 93 are normally pressed outwardly away from sheets 48 by springs 1 0() to release the grippers from sheets 48. To cause the grippers to engage sheets 48 as the grippers l130` a plurality of 95 super-imposed sheets simultaneously so that for the sheets ,L18 to hold the These grippers 110 toward sheets 48, washers 98 12e wardlyby springs arms 93Cwill engageithe inclines 92b and riding up on the same the levers 93 will g. 5, l guides 92'. are; inthe direction ol' thatwhen the gripper 1. normal] swung out'- 100,` are carried by vchains 89 tothe front' lower corners of guides 92 the travel in the direction of the arrow .in Fi the t 'forward ends .1921 `of clined 'upwardly and 1n travel of the sheets, so levers 93,v which are by v b@ g press'the y@flippers 95 the sheetsk'jto bars 90,

of guides 92, whereupon springs .100 will swing the gripper. levers 93 'outwardly and lift the grippers 95 away. from the sheets, and out of vertical alinenient therewith, to permit the grippers to pass the edgesv of the sheets as the grippers are carried aroi'lnd by uthechains 89. Thus, several grippers may simultaneouslygrip sheets 48'upon cross bars 'sheets are"pulled equally and simultaneously beneath the The' sheets `48,.vv between the punches. andthe grippers preferably slide upon the supporting plate 101.

reets 48 are 'tobe pulled simultaand coincidently with the travel sheet 3, and to an extent proportioned to the i lengthl of the respective perforations and spacing desired lin sheets 48. To this end I 'provide shaft 86 with .a detachable gear 102 that meshes with a gear 103 pivotally carried by an arni 104 hung upon or concentric with shaft 38, and gear 103 meshes with a gear .103a secured on shaft- 38, or secured to ratchet 39, and by means of arn 24, link 36, arrn 37, dog 40, and ratchet 39', the shaft 86 Will'be rotatedstep by step simultaneously with the step by step feeding of drinn 13 by ratchet 22.` Gears 102 of' different diameters may be used as desired in accordance withthe step by step feeding movement de- 8, so that said sheets may be feda'gre'ater or less distance each step ac- -crdingto 4the length of perforations and spacing desired in sheets 48, and 4arm 104 ma f be held inset position, in accordance .with the gear 102 being` used, by means of a ina .threaded aperture in frame 1 and passing through a curved slot For greater range arm 104 the screw 105 may neously 'bi adjustmentof 102 has been correspondingly increased.

in 4order to guide sheets 48 accurately through space 52 under the punches, I provide'guide fingers 107 that project upwardly -froniblocks 108 (Figs. 2, 3 and 5) in front Aif spaceY 52.'.whieh blocks .travel in ways 109 insertion of upon which belt the sheets 48 rest.

of bed 110 (Fig. 5) and at 111. is a shaft.4 journaled to rotate in a support 112 (Fig. 2) but having no longitudinal movement, whlch shaft near its ends has right and left threads 111a blocks 108, a handle 113von said shaft permitting it to be rotated. By rotating shaft .1.1.1,to the right or left the guides 107 will be caused to approach or recede to centrally guide sheets 48 as they travel yunder punches 49.

I have shown means for winding the perforated sheets 43upon music spools 115 sup ported upon a frame 1a at the end of frame 1 or as an extension thereof. One end of the shaft 115Il rotate in a bearing 116 shown carried in a socketpiece 11.7 supported on side bar 1b of frame 1l and containinv a spring 118 to press said bearing outwardl a screw 119 passing through a hole in said socket piece and screwed into bearing 116 limiting the thrust of the latter by said spring (see Figs. 23 to 27). '.lhe shaftportion 115b of each spool 115 enters asocket 120a in a shaft 120 journaled in a bearing in a side bar 1b, and shaft 115b is shown provided with projections 115 C that enter slots 120b in the ends of shafts 120, whereby spool 115 -is rotated. Bean. ings 116 may bepushed back to permit the spools 115 into and removal from their bearings. Shafts 12() are provided with pulleys or rolls 121 upon which a belt 122"travels for rotating the spools 115, said belt passing over pulleys 123 and 124, pulley 123 being loose on a shaft 125 jour-y na'led on frame 1a, pulley 124 being loose upon a shaft 126 su orted on frame la. Shaft- 125 has `fast andpfbose pulleys 127, 128 and also carries a fast pulley 129 from which Ya crossed belt 130 passes over pulley 124 for rotatin the latter; shaft 125` also carries a fast pu levi7 131, and shaft 126 carries a pul-l ley 132, over which pulleys a belt 133 passes At 135 are friction rollers bearingr upon vbelt 122 and serving to press the latter upon the corresponding pulleys 121, and the pulleys 135 are pivota ly carried upon arms 136 which may be arranged in pairs on opposite sides of each roller 135 (see Fig. 23), 1n the outer ends of which arms the shafts 137 of rollers 135 are journaled. Said armsA 136 are pivotally supported upon bars 1b and their rollers 135 are independently held pressed 'upon belt'122 by weights 138 connected wlth the outer ends of arms 136 by suitable connections 139. .With the arrangements above described, the sheets 48 are passed over belt 133 and" respectively connected with corresponding music spool 115, and driving belt 140 on pulley1'28 may continuously rotate said belts, and as belt 122 is rotated in the direction of the arrow fr in Fig. 22 the music spools will be caused to rotate to wind sheets 48 thereon respectively, and belt 122 will slip upon pulleys 121 as re. quired torelieve the strain on sheets 48, belt engaging' corresponding threads inof each spool 115l is supported to 133 assisting in supporting and carrying said sheet along.

'Ihe reels 48'"i of the paper rolls for the sheets 48 to be perforated may be supported in a suitable frame A located adjacent the punches 49, from Which said sheets mayl pass one upon the other through space 52 (see Figs. 27 to 32). Said reels at one end are supported upon pivots 48b adjustably carried by blocks 48C secured upon frame A,

, and the opposite ends of said reels are deposite side of said frame. A

4tachably connected With short shafts 48d Slack in the sheets 48 between their reels 48:l

` and punches 49 may be pulled out by hand to reduce strain on sheets 48 as they are drawn from the reels, and as a convenient means for produc-ing such slack in said sheets I have shown shafts 48d'as provided With sprocket Wheels ai receiving endless chain b for rotating said reels. On one of the shafts 48Vd is journaled a sleeve c provided -with a crank or handle d carrying a sprocket e receiving a chain f from a sprocket g secured on a shaft 48d for operating chain b. I

I have shown the reels and their shafts 48 d as arranged in series of three tiers, and the chain passes over some sprockets and under other sprockets, whereby the chain is caused to properly engage said sprockets for producng the desired slack simultaneously in the various sheets 48 at Will. rlhe sheets Will pass properly from their reels according to the direction of rotation thereof. I have also shown means whereby duplicate master sheets 18 may be produced in accordance With master sheet 3,and for this purpose I provide the following arrangement: At one end of frame 1 adjacent punches 49 is journaled a shaft 141 in suitable brackets 142 upon which shaft may be mounted a roll or drum 143 provided With pins 144 (Fig. 17) arranged similarly to roll or drum 13 and its pins. Shaft 141 also carries a ratchet Wheel 145 engaged -by a spring pressed pawl 146 pivotally carried by an arm 147 journaled on shaft 141 and pivotally connected by a link 148 With arm 24a (Fig. 1), the arrangements being such that drum 143 Will be rotated step by step simultaneously and coincidently with the rotation of drum 13. To cause the duplicate master sheet 18 (Fig. 28a) to be drawn along under punches 49 by drum 143 I provide means 'for producing the perforations 181L near the edges of sheet 18 to engage pins 144 of drum 143. To this end the punches 49a (see Fig. 3) at the ends of the series of punches 49 are controlled separately frbm the punches 49, as by corresponding pneuinatics, and said punches 49a are to punchA the holes 18:L in sheet 18 at definite distances apart and preferably corresponding to the holes 3a at the sides of master sheet 3, irrespective of the perforations 18b produced in sheet 18 for the musical composition. To this end I conneet the passage 65b of the pneumatics ofthe end punches 49L with a tube 150 (Fig. 3),

tube 151 extending from tube 150 to one end of suction chamber 2c of bridge 2, (Figs. 1 and 7) and the tube 152 extending from the opposite end of said chamber and being connected With a coupling 153 from which a tube 154 leads to tube 150. Coupling 153 connects by a tube 155 with a passage 156 (Figs. 4 and. 13) in a block 157 secured on frame 1, the other end or port of which passage is cont-rolled by a valve 158 carried by a spring or arm 159 operated by a dog 160. Dog 166 is pivotally supported, as at 161, upon frame 1 and is provided With a spring 162 to cause the end 16()a of said dog tb normally tend to lift spring 159 and valve 158, and the end 160b of said dog engages a toothed Wheel 163 on shaft 141. fr hen dog 160 rides upon the surface of Wheel 163, arm 16()a will reiease spring 159 and valve 158 Will close passage 156, and when the end 166b of dog 160 enters a notch in Wheel 163 kits end l160a will raise spring 159 and valve 158 and open passage 156. rIhe effect of this is that when arm 160b enters a notch in Wheel 163 air enters passage 156 and flows through tubes 154 and 150 to the corresponding pneuinatics 65 of the end punches 49a, Whose springs Will then push the end slides 6Ga over punches 49, so that upon the next descent of head 53 holes 18a will be punched near` the edges of sheet 18, and When arm 160b at the next stroke of arm 147 rides up on the surface of wheel 163, valve 158 will close passage 156 and the suction through tubes 151 and 152. cornniunicatinfr with the corresponding pneumatics 65, Will cause their'diaphragms 66 to operate their levers 63 to pull back slides 60a from punches 49a, -Whichwill be held retracted until arm 160? again enters the next notch in Wheel 163, and so on each time that said arm enters a notch in wheel 163, holes 18a at opposite ends of sheet 18 Will be punched, thereby producing series of such lholes in said sheet at definite distances apart corresponding to the distances between pins 13 of drum 13 and pins 14.4 of drum 143.

The duplicate .master sheets 18produced as above set forth may be used the same as master sheets 3, Wherebythe duplicatingT of master sheets may be simplified and their cost reduced. 'I he master sheets 18 are fed through the machine in the direction reverse to the feeding of sheets 48 as shown by the arrow 'y in Fig. 6. Y1 hen the master sheet 18 is to be produced the guides 92 may be 13o LA i.

descent of head '53 without sheets.

removed to permit the gripper levers 93 that 'extend upwardly from chains 89 to swing outwardly auf'ay from sheet 18, and the latter may slideover across bars 90 and plate v101, and `the gears of chains 89 may be stopped, as by disconnecting link 36, to prevent movement of the chains. l have shown tube 150 connectedl at opposite ends b r tubes 151, 154 and 152 With lsuction chamber 2c to assure sufficientsuction in the corresponding pneumatics 65 for quick simultaneous action of the end slides n.

In Fig. 1 I have shown suction tube 2(l connected Witha three-Way cock 165 from which a tube 166 may lead to a suction pump, (not shown) and a tube 167 may lead to an air force pump, whereby when valve 165 is turned to one position suction through the pneumatic devices may be produced, and when turned to another position the suction pump will be cut ofi' and the force pump may supply air under pressure through tubes 167 and 2e to blow dust and accumulations out of the ports 2e and orices 2a The. operation of my improvements as above set forth may be described as'follows:

T he master-sheet roll 4 being mounted in its.

bra-rings, said sheet is placed under over bridge under bar 29, over and its holes 3a guide 12, drum 13 iittcd upon pins 13a, thence under roll 35, and its end attached to take u reel the bar 29 then being adjusted to cause perforations 3b to properly track over the orn'iccs of the bridge; the head 53 is elevated and sheets 48 are passed through space 52 from their reels and are carried forward and 'Iitted on cross bars 90 and held by grippcrs 95, chains 89 then being suitably operated by means of handle 85a cn shaft 85 (Fig. 1). Pulley 28 is then connected by the clutch with shaft 27, and drum 13 and grippers 95 are advanced te i by step, the latter pulling sheets-48 simu taneously under the punches, and drum 13 pulls sheet 3 across the bridge. As the perforations 3b of said sheet pass over the orifices of bridge 2 the corresponding pneumatiis will push the corresponding slides 60 over tht` associate punches 49, but the relation of the parts is such that said slides will be pushed outwardly only at such times as ,the punches are elevated from sheets 48, for the step by step movements of drum 13 and grippcrs 95 only take place when punt-hes 49 are abov sheets 48, and during the periods of rest of said drum and grippfrs the operating slides G0 are held over the punches and head 53 and the punches then descend, but sur-h punches 4i) as are not at such' time opposed by projefting slides 6() normally rest on the up, errnost sheet 48 during the perforating thc understood that by p feeding of master 48 suflicient time of It will thus be reasonof the step by ste sheet 3 and stock sheets 4carried by the head to head 53 reciprocates,Y

rest is provided for head 53 to liftl the punches from sheets 48, whereupon during the step forward of said sheets the slides 60 are appropriately shifted as required to pro'- duce the desired perforations in sheets 48 during thel next down stroke of head 53 While the sheets 48 are at rest, and so on. When duplicate master sheet 18 is to be penlorated a similar simultaneous feeding of sheets A3 and 18 talres place, While during 'the periods of rest of'. saidsheets the punches are operated, and at the proper times arm 1601 of dog 160 enters the notches in Wheel 163 to cause the corresponding pneumatics 65 to push the slides()a over punches 49a, to cause holes 18a to'be punched in master sheet 18 at the appropriate distances apart, irrespective of the perforations 18b at sue-h time being made in sheet 18.
