` Lesesaa- Autographic Registers, of which the following' isa full, clear, and exact description.

My inventionrelates to autographic registers from whichpaper strips having a longitudinal series of alined "equi-distant perfo- .rations or filing4 holes, are, after havin been' written upon, extracted and torn o and relates'more particularly to the type of registers 'illustrated and described 1n myV application for Letters Patent of the United States, led ylVlarch- 27, 1.916, Serial No.

The object of my invention'is to provide an extracting mechanism which includesl a .vreciprocable' carrlerhav1ng rigid 4 pins mounted thereon, and a spring mounted channelA through which the strips of paper pass, and which impales the said strips upon said pins when the ling holes 'of the strips' come beneath and in register with the pins as said strips are being extracted from the mechanism the channel drawing saidstrips ol' of the pins lwhen said carrier is at the limit of its extracting movement. These andother objects I accomplish by the means hereinafter fully described, Aand. as particu-` larlypointedout in thel claims.

rateateaoet. ae, rare! disposed platenthe side'edges of which are secured to and connect the side-frames near 'their upper horizontal edges, and C the usual cover, which, in View of the fact that my improvements donot affect the same, is not thoroughly illustrated in said drawings.

The discharge end of the platen is i'ore- 'shortened and terminates a suitable distance back of the 'forwardmost portion of the vertically disposed edges .of the ends of the side-frames, andbetween the transverse vertical plane of the forward' transverse end edge of the platen and the transverse vertical planel of the forwardmost part of *said side-frames a transversely disposed fiat horizontal plate or tray D is placed, whose hori- -zontal surface is slightly below that of said platen. The ends of tray D'hav'e blocks a,

a, securely mounted thereon which support the ends' of the tearing-blade E,-whicli latter consists 'of a flat plate that bridges across the vrear portion 'of the tray from side-frame to side-frame, 4and has its forward edge inclined vdownward at a suitable angle, subtantially as shown in Fig. 2 of the drawings.

0n either side of its centerof length the tearing-blade has rigid' pins G depending therefrom 'that terminate about half-way between'said blade and tray D, and, preferably, have their extremities rounded, as

shown. These pins G areadapted toextend down through openings in the. upper and lower horizontal'plates and o of a floatingchann'el, which plates are arranged between the tearing-blade andthe tray and extend from near one block a to the oppoby short vertically disposed tubesl 8 into the upper ends of which the extremities of pins enter when the floatingchannel is` at the Tubes 8 havel their lower serew-threadedends reduced in diameter and passed through corresponding openings in` the forward ends of longitudinally disposed leaf-springs4 9, and nuts 10 are screwed onto said threaded ends to secure the tubes to said springs.

Thevrear ends of springs 9 extend back under the platen a suitable distance and are secured to the longitudinal members 12, 12`

of a U-shaped reciprocable frame that are held against the underside of the platen by screws 13, 13, (located near the forward edge of the platen), and by screws 14, y14 (located near the rear ends of said members), which pass through longitudinally elongated slots 15 15 and 16, respectively, which limit the throw of said reciprocable frame. The forward ends of said members 12 extend beyond the forward end edge of the platen and are bent downward slightly, and tray'D is secured to and supported upon these forward ends, and

both said tray and said ends of members 12 are provided with openings up through which tubes 8 freely pass.4 Immediately in front of screws 14, 14, members 12, 12, are connected bya tie-strip 17 and the reciprocable frame of which it forms a part is kept at the limit of its rearward movement by -1 means of a coil contraction spring 18, the ends of which are, respectively, connected to ed upon a transverse rock-shaft 22, which is journaled in side-frames A, A, and has one.

end extended through its bearings and, provided with a crank 23 with which to rock it,

and between the bossof this crank and the adjacent side-frame shaft 22 has a coilspring 24 surrounding the same, one end of which is secured to said side-frame and.

the other end to said shaft in any suitable manner. rlhe rocking movement of shaft 22 is limited by means of an L-shaped arm 25 securely mounted thereon mediate its end at its'angle near the bearings of said shaft in the side-frame opposite the crank. The lower branch of arm 25 is adapted to engage the lower end of a segment shaped flange 26 projecting from the last-mentioned side# frame when tray D is at the limit of its rearward movement, and the extremity of the upper vertically disposed branch of said arm 25 is adapted to engage the rear surface of said flange 26 when the tray is at the limit ofits forward movement.

When crank 23 is turned rock-shaft 22 is turnedsuiciently to cause arms 20 to engage arms 19 and push the tray forward to the limit of its forward movement and when the crank is then released, spring 24 on lsaid shaft 22 and spring 18, hereinbefore referred to, will return the tray to the rearwad limit of its'movement. When it does this, it is necessary. for pins G, which have been previously passed through the filing-holes in 'said paper strips, to have said strips released therefrom, to prevent said strips from being buckled and carried to the rear with said tray. This I accomplish by means of a longitudinally.reciprocable wedge 27 the upper fiat side of which is held in sliding engagement with the underside of the platen' by means of a screw 28 which extends down through a longitudinally ,elongated slot 29 in the rearward extension30 of the wedge.

'The forward end of wedge 27 terminates (when at .the'limit of its rearward m'ovement) a short distance to the rear of the forward end edge of the platen.` A short distance back of this forward end the underside of the wedge is beveled or incl-ined down' boss of arm 33 is provided with a segmental depression or recess 35, and shaft 22 is provided with a pin 36 that projects into this recess 35 and is normally kept in engagement therewith by a coil expansion-spring 37 interposed between said boss and a sleeve 38 secured on said shaft. may have the forward ends of segmental leafsprings 39 (whose rear ends are secured to the underside of the platen) bear down upon the same. When shaft 22 is turned'to move the tray forward it moves independently of arm 33 until pin 36comes in contact with the lower terminus of recess 35, or in contact with the end of a gage-screw 40 tapped through the lower portion of the boss of said arm, whereupon arm I 33 is rocked and propels wedge 27 forward and moves bridge 31 and leaf-springs 9 downward, and the latter move tubes 8 and plates 5 and c of the channel downward, and by the time the -tray reaches the limit of its forward movement the plate d strips the paper from pins G, and when this happens and the operator releases the pressure on crank23 the tray immediately returns to the limit of its rearward movement, and `when pin 36 engages the up per terminus of recess 35 wedge 27 is moved If desired, bridge 31 Leashes rearwardly to the limit of its rearward move' ment.

It will-be noticeddthat, owing tothe manner inwhich arm 33 1s actuated, the rearv ward movement ofthe wedge is delayed` and f thus keeps the channel in aposition "below pins G until after said pins have moved to the rear of 'the filing openings of--the paper drawn. In order to-prevent'the strips of tangular tension-plate 41 is employed whose upper horizontal edge lextendsup through a recess in the forward edge of the platen and presses the paper toward cross-bar 7. The lower edge of this tension-plate is provided with a `knuckle that is loosely mounted upon a transverse stationary shaft 43 whose ends are secured in the side-frames, and the upper edge of said plate is kept pressing against the paper in the manner just stated, by a spring 44 whosev central yoke bears rearwardlyagainst the plate and'whose coiled ends are wound about said shaft 43.

The continuous paper strips usedm conjunction with my improved register have a longitudinally arranged series vof equi-distant perforations that are separated a d1stance rcorresponding to the length of the record or form printed thereon, whigh latter determines the length of strip which'is to be withdrawn. My improvements are adapted to engage these perforations one at a time and to advance the strip just far enough to enable the operator to grasp the advance `edge of the strip and then release it, leaving it to the operator to pull the st rip out of the machine a distance corresponding to the full length ofthe record or form, and to bring the next perforation in vertical register with the extracting pins. There are usually two of these series of perforations 1n the paper strips, one near each side edge thereof, and

when the operator desires to extractthe strip he grasps the handle of crank 23 and turns rock-shaft 22, and arm 20 projecting therefrom engages arm 19 and moves the reclprocable frame forward.` The tubes 8 wlll have pushed the floating-channel upward so that pins G will have passed through the perforations of the strips before the forward movement of said frame commences, therefore as `said frame moves forward, the pins that are mounted thereon, draw the strip forward a distance corresponding to the sweep o f arm 20. When the paper strips reach th1s advanced point, wedge 27 will have depressedl springs. 9, 9, through the medium ofbridge 31,l and tubes 8 will move downward with thesesprings and the ioating channel will strip the paper olf of the pins, and the tray and conjunctive devices will return back to their orlginal posltions, When the paper fra me againstl retraction. stantly, but lightly, urged toward teeth 47 .strip has been withdrawn until the next er- 4 forations are in position to be 'enga e by pins Gr the machine will be ready tor the next extracting movement.

It may happen' that the operator having turned` crank'23 'to partially advance the paper strips 'in the machine, suddenly notes that a correction or addition must be made in the matter he has written. v'This makes it necessary to hold the U-shaped reciprocable frame in an advanced position against the pull of springs 18 and 24. vFor this purpose I provide a C-shaped pawl 46 fulcrumed mediate its ends to the underside 'of the platen at a point back of the rearward'extension 30 of the-wedge when the wedge is retracted. One end f this pawl is pointed and adapt-ed to engage teeth 47 formed in the adjacent longitudinal edge of the nearest member p12 of the frame, this end of the pawl beingslightly longer than the distance from its pivotvto the teeth and extending forwardly of the pivot thereby holding the Tawl 46 is conby an attenuated spring 48 which extends rearwardly from its opposite end into con- Y vtact withV the set-screw which secures the rear end of spring 18 to the platen. In the V advancement of the frame the pawlv will ride over teeth 47 successively and will hold the frame at any desired partially advanced position when the` operator'stops turning crank 23. But to preventengagement between teeth 47 and the pointed end of the pawl during ordinary operation of the machine, I form the opposite end of the pawl with anoutwardly turned finger which rides -upon the inwardly exposed surface of a cam 45 projecting rearwardly' from eXtension 30 of the wedge. From its root in extension 30 lthe inner face of cam 45 parallels the toothed edge of member 12 for a dis* tance somewhat less than thefull path of movement of the wedge. But at its tip the cam diverges sharply from the member l2. rlhis divergence is suiicient to draw the4 pointed end of the pawl a considerable distance awayfrom the toothed edge of member 12 when the rotation of crank 23 has fullyv advanced the frame and wedge. parts in this .position the operator removes his hand from crank 23 and the combined pull of springs 18 and 24 jerks the frame and wedge back to retracted position before the light pressure of spring 48 can bring the pointed end of the pawl back to teeth 47. In other words, the finger on the pawl jumps from the tip of the cam to the root causing the pointed end of the pawl to skip by all the teeth 47 and seat itself in advance of the forward-tooth, as shown in Fig. 6. j

A plurality of superposed strips of paper are customarily used in machines of this With the character, each strip having perforations for engagement by posts Gr. A careless operator will occasionally draw thev lowest strip ahead of the upper ones, so that the perfof rations of the lowest one move ahead ofthe perforations in the upper ones. This causes the webs of the upper strips to overlie the perforations of the lowest one and necessitates advancing the upper strips upon the lowest one to bring all the perforations in register 'with each other and the posts. 'To so advance the upper strips, when the frame is in retracted-position, requires separation` pose arm 33 is provided with a handle 34 and slidably mounted on shaft 22, so that it 'can move to the left-viewing Fig. l-suiiiciently to clear pin 36 from recess 35 and permit thev arm to be rotated forwardly from the position shown in Figs. 1 and 5, the expansion spring 37 yielding `horizontally to permit this movement. To facilitate such action of the v parts the shoulder of metal formed at the upper forward end of recess is rounded as' shown, in outline in frontV elevation, in Fig. 1, and, by shading in side elevation, in. Fig. 5, and .handle 34 is twist-ed slightly to present its broad surface conveniently to the left thumb o f the operator. This forward movement of'arm 33 carries wedge 27 forward independently of shaft 22 and the reciprocable frame-which are at rest in retracted positionand hence results in freeing the strips. of'paper by lowering tubes 8 through the medium of bridge 31 and springs 9. The several strips may now be shifted relatively to bring their perforations in register. Should it happen that the apertures, when brought into register with each other, stand somewhatforward of posts G, the operator will not wish to buckle the strips by attempting to push them backward in the machine untilthe alined apertures shall register below the posts. Instead he can advance the posts into vertical alinement with the apertures by slightly rotating crank 23 and as he releases the crank pawl 46 will engage one of teeth 47 to hold the frame and posts-in this partially advanced osition; the operator may then grasp hand e 34 and retract wedge 27, thereby impaling all the strips on posts G and returning pin 36 to its normal position in recess 35. The parts will remain in this sli htly advanced position leaving the strips at on the platen, until the operator completes his writing and rotates crank 23 mesma to advance the frame and wedge the full stroke.
