MARCUS S. ROOSEVELT, OF DETROIT, MICHIGAN, ASSIGNOR TOTHE HAMILTON AUTO- GBAIHIC REGISTER 00., OF HAMILTON, OHIO, A CORPORATION OF OHIO CONTINUOUS STATIONERY APIABATUS Application filed July 22, 1929. Serial No. 379,921.

My invention relates to improvements in apparatus to be used in filling in forms arranged in continuous sheets and objects of my improvements are to secure greater accuracy of alignment of the various sheets, to obviate the confining of air between the separate sheets and to avoid accidental displacement of the sheets from the apparatus.

In the accompanying drawings:

Figure l is a side view ofan apparatus embodying my invention.

Figurev 2 is an end view thereof. The strips of forms being removed and a part being broken away tomore clearly show the construction. I i

Figure 3 is a sectional elevation, to an enlarged scale, of the upper right hand portion ofthe apparatus,,as shown in Figure 1.

Figure 4 is a detail sectional elevation of the clutch for preventing the accidental dis placement of the strips of forms.

Figure 5 s a section of the upper left hand portion of the apparatus, as shown in I Figure 1. Figure forms.

o t Figure 7 is an elevation looking from the left of Figure 5.

Figure 8 is a sectional detail.

. v 2 is a standard supporting a horizontal frame 3 at its upper end. dis a round bar extending transversely across the frame between the side pieces thereof. 6 is a table upon which the stationery-is received to be 6 shows a section of the strip of filled in by a typewriter adapted to the purpose and indicated at 28 in Figure 1. 7, 7,

are stationary positioning pins extending [upward from the table6 a short distance near the deliveryedge thereof. 26 ,is a

presser bar adapted to act upon the surface s of thepaperupon the table 6. There are holes in the; bar 26 to permit the passage of the pins 7. 24 is a treadle adapted through [a connection'25 to raise the presser bar 26" from the form strips and above the pins 7, 7.

8, 8 is a vertical frame having two' side pieces, each of which has a vertlcal central slot 86; therein. 9, 9, 9, 9 and 10 are rollers.

adapted to rotate in the slots 8a and slide lon itudinally therein. '11 indicates strips of forms, one strip passing under each of the rollers 9 and adapted to receive. a transfer frame v 15 indicates stationary guide rollers arranged horizontally, transversely'of the machine with their outer'edges in a substantially'vertical plane, in line with theouter edges of'the rollers 9 and 10.

Bab is a horizontal slot extending from the fupper end of the slot 8a to the outer edge of the side piece of'the frame 8 and bridged by the piece Sac on the outer surface of said side piece. The slot 8a?)- permits the entrance of a pintle of the roller 9' or 10. into the slot 8a.

. 16 is aguide roller extendinghorizontally across, between the side pieces of the frame 8.below the rollers lowith its outer edge inthe plane of the outer edges of said rollers. 'lhe'forni strips 11. pass from the roll lase'verally under the various rollers 9 to theroller'16 and then over the several rollers 15 to and over theiguide bar 5'and then to' and along the table 6and have at their delivery ends the apertures 1200 (Fig. 6) engaging over the pins 7, 7 The rollers 9 act by their. weight to put the strips 11 under slight tension to 'hold the same in place.

" 15a is a, roller extending transversely across the frame 3. Each of the ends of the roller 15ais mounted. inan inwardly extending horizontal arm 20aof a bell-crank The sheets 11 and 12 are .wound upon a roll 1e suspended in hangers 1 3 from the lever 20 pivoted at21 to a sidepiece of the frame 3 and located .so that its outer edge is in the plane of the rollers.15andabove 'the rock shaft 17 "a counter-clockwise the machine under the the same. 206 is an outwardly extending arm of the bell-crank lever 20.

There is a slot 23 in the arm 20?). 22 is weight of the roller maintains the strip v12in tension, which tension acts upon the roller 15a to hold the bell-crank lever rocked to the limit ofit s travel,in aco unte rclockwise direction. I 'f' r 17 is a rock shaft pivoted at its ends in theuprights of the frame 8 and ext'ending parallel and adjacent to the outer edge of the roller 16." 18' is a clamping cam upon adapted, when turned in direction to engage againstthe form strips passing over the roller 16 to prevent the retraction-ofsaid strips. 19 is a connecting and joining an eccentric point of the rock shaft 17to the over the 'roller 15a is held in tension, the

bell-crank lever 20 is rotated, turning the rock shaft 17 and drawing the clamping cam '18 away from engagement with the strips upon theroller 16. Shouldthedelivery end of thes'trip 12 be released, thetension would no longer exist and gravity wouldca rry the arm 2Ob clownward,forc- 'ing the cam 18 against the strip 12 and roller 16 holding the strips ll and 12 in position and not j allowing "them to fall ers 9 and 10. V 7

Of course the'transfer sheets llare held in the same'way as the sheet learn at the same time.

V The arrangement of the rollers "'15, 15 win a substantially 'verticalplane obviates the trapping of 'air'between'the 'fornrstrips and" the relative 'movement or creeping or said strips, so thatthecopies from'the impress 1 on the orlglnal sheet comes accurately in place on the transfer sheets.

All'the form strips coming from the'rollers 15"and 15a rise somewhat to engage over the bar 5 and approach eajcih other gradually, so that the air betwe'enthe strips is'com v pletely" displac d The various strips where they come togeth'er simply lie against each fother "without pressure. or friction one fagainst the other, so that the tension on each sheet is between the engaging pins 7 andthe weight roller.

As each strip is free to move relative to the others it is accurately positioned by its engagement with the pins 7, 7. And each strip exerts its own tension against said pins and'does not also carry a part or all the tension of the ther strips, as has, hitherto occurred in other forms'of the apparatus.

If the form sheets are accidentally released they will not fall from themachine, as in previous devices,,- but will I be held by I the automatic action of the clamp '18. 7 Thegf orm strips are sometimes stored in successive folds instead of rolls, in which case :shelf would be substituted for the shaft of the roll and the strips would be delivered from this source in thesameway;
