MATERIAL FEED CONTROL FOR IMPRESSION APPARATUS: I

Application filed May 16, 1921. Serial No. 469,969.

To all whom it may concern:

Be it known that I, MALCOLM L. Cossrrr, a citizen of the United States, and a resident of the city and county of San Francisco, State of California, have made a new and useful inventionto wit, Improvements in Material Feed Controls for Impression Apparatus; and I do hereby declare the following to be a full, clear, concise, and exact description of the same.

This invention relates particularly to an impressionable material feed for autographic registers, typewriting, calculating and bookkeeping machines and to all classes of impression apparatuses.

The principal object of my invention is to provide a new and novel mechanism for maintaining a single sheet or plurality of sheets in superposed relation, in absolute registry during the introduction and passage through apparatuses and devices of the type above described and to provide means whereby suitably located apertures in said sheet or sheets will be made to register.

In type impression, recording or duplieating devices used as oflice equipment, it ofttimes happens that a carbon record of an original record does not have the impressions thereon in the same location as placed so on the original. W'here the record and second sheets are printed as standard forms, such as bills of lading, receipts and the like, it is desirable that any record made on the original sheet in spaces left for that purpose should likewise appear in a corresponding space on the reference or second sheets beneath. It is thez'obiect of this'invention to provide a mechanism that .will ali n the original and record sheets prior to wrlt- 40 ing thereon, whereby the record sheets will be fac-similes of'the original. Other objects and advantages will appear as this description progresses.

In this specification andthe annexed drawings, theinvention is illustrated in the form considered to be the best, but it is to be understood that the invention is not lim-,

' ited to such form, because it may be embodied in other forms, and it is also to be understood that in and by the claims fol lowing the description it is desired to cover the invention in whatsoever form it may be embodied.

In the accompanying two sheets of draw- 1ngs Figure 1 represents a sectional elevation through an impression apparatus having a material feed applied thereto constructed in accordance with my invention.

Figure 2 represents a sectional plan view of Figure 1..

Figure 3 represents an enlarged cross-sectional view taken through Figure 2 on the line 33.

Figure 4 represents a sectional side elevati'on through Figure 2 taken on the line 44.

Figure 5 represents a diagrammatic View of the sheets of paper stock in disassembled position.

Figure 6 represents'a diagrammatic side elevation of the normal relation between the paper feed rolls.

Figure 7 is a similar view to Figure 6 with the paper stock passing between the pressure and feed rolls.

Figure 8 represents a sectional end e1evahingedly connected to the end wall 3 of the' base member at 3'. The opposite end of the base 1 is provided with a vertical wall 4 having a spring detent 5 mounted thereon, adapted to engage a latch memberfi secured on the. underside of the plate 14. The

spring member 5 is provided with a pushbutton 7 for the purpose of disengaging it from the latch and thus permitting the entire casing to be swung on the hinge pin 3 into open position for replenishing the paper supply of rolls 8, 9 and 10 suitably mountedon guide shafts extending transversely within the interior of the casing side ase I walls. The ends of the paper from the 'va rious rolls, 8, 9 and 10 are then passed over the edge 11, writing plate 12 and between the material feed mechanism generally designated by the numeral 13 in stacked relationship.

The usual; construction of standard impression devices is to have the cover plate 14 of the housing provided with an aperfeed roll 18 mounted on a shaft 19'journaled in the side walls 20 and 21 adjacent an end of th casing 2. One end of the shaft 19 is provided with a suitable handle 22 for imparting a rotative movement to the roll 18. The cover plate 14 is provided.

, with a substantially cylindrical housing 24,

in alignment with the roll 18, and has the shaft 25 concentrically mounted therein in suitable bearings 26 and 27 formed in the respective end walls of said housing. The shaft 25 is provided thereon with a plurality of rollers 28 and 29 spaced equidistant from the ends of the housing and which are adapted to contact with the feed roll 18. whereby the sheets of material placed between the feed roll 18 and the pressure rollers 28 and 29 are fixedly maintained therein and movable forwardly or rearwardly with each rotation of the handle 22. Although. the material feed mechanism is de-' scribed particularly with reference to an impression device specifically known as an autographic register, it is to be understood that the said feed mechanism in the modified forms, such as indicated in Figures 8 through 12 inclusive,. could be applied equally as well to typewriting, calculating or bookkeeping machines or any type impression device of whatsoever character.

It is standard practice, to provide the sheet or sheets of material with aligned holes therein spaced upon predetermined centers for the purpose of accommodating such sheets to standard filing apparatus. In the operation ofthis device it is desirable that the pressure rollers 28 and 29 be spaced at distance equivalent to the registering apertures provided in the material whereby the periphery of said pressure rollers will proj'ectthrough said apertures into contact with the outer circumference of the 7 feed roll 18. -It will be thus seen, by reference to Figure 6, that the pressure rolls and feed roll will remain in frictional contact during which period no forward or rearward movement of the material may be effected. handle 22 'to be rotated without disturbing the position of the aligned sheets over the writing surface 12'hold1ng .the same in constant readiness for quick use. To pass This construction also permits thethe paper from the casing and outwardly so that it may be torn therefrom an auxiliary pressure roller 30 is provided, eccentrically mounted around the shaft 25 and revolubly journaled in the'ends of a forked supporting bar 32. The bar 32 has a central projecting stud- 33 extending through the ing downwardly on the button 34 against the tension of thespring 35 placing the said sheets of material as in Figure 7 'After the roller 30 has been brought into contact with the paper stock, the operator grasps the handle 22 on the feed ro1l 18 and rotates the same, forcing the paper in a direction \corresponding with the movement of the handle so that the pressure rollers 28 and 29 are forced out of the registering apertures in the material and made to contactwith the outer surface of the top sheet. The spacing between the pressure rollers and the feed roll is .of .suific-ient-distance that the thickness of the material will effect a frictional engagement between the respective rollers.

Presuming that the auxiliary pressure roller 30 has been placed into contact with the material or paper over the feed roll and the same moved forwardly in the direction of the arrow in Figure 1, the hand of the operator is then withdrawn therefrom'permittlng the pressure rollers 28 and 29 to function by moving the material forwardly until the next a'd acent pair of apertures come into registry with the respective pres-.

machine are carried on in the described manner.

The modification illustrated in Figure 8 consists of a housing -24 having the feed roller 18 journaled in the end walls 26 and 27 thereof and provided with a handle 22 for rotating the same. 'lhe'pressure rollers 28 and 2!) are mounted on the cross shaft 25 extending transversely within the casing roller 30 into contact with the stacked 9 I 2 having the ends thereof journaled in suitable pivoted brackets 41 and 42 mounted on the cross-rod 43 journaled in thebearings 44 and 45 provided on the side walls 20 and 21. The auxiliary roller 30 is mounted on a cross shaft 46 having its ends bearing in the respective pivoted bracket plates 41 and 42 and is placed intermediate the respective pressure rolls 28 and 29. The pivoted bracket plate 41 is provided with a project-- ing end 47 in the form of a finger piece to be used by the operator in withdrawing the pressure rolls 28 and 29 from contact with the feed roll 18, or placing the auxiliary roller into contact therewith against the tension of the spring 48. The spring 48 has an end thereof joined to the plate 41 and the opposite end, secured to the casing as at 49. This modified form of feed mechanism could be more readily adapted to typewriting, calculating or bookkeeping machines than the form indicated in Figures 1 through 7 Where in the operation of sheet feed mechanism such as described in this application, it is found that the sheets of placed in the desired position, the pressure rollers 28 and 29 are brought into contact with the material so that the apertures in the said papers register with the respective spaced pressure rollers. In this position rotativemovement of the handle 22 will not cause a corresponding movement of the paper. When it is desired to advance the material from the register the operator grasps the finger member 47 on the pivoted bracket 41 throwing the pressure rollers 28 and 29 out ofcontact with the roller 18 placing the auxiliary roll 30 intocontact therewith. The auxiliary roller 18 is held in contact with the material fora suflicient. period of time to enable the handle 22 to be rotated and the material advanced from the housing 24 after which the pivoted bracket 41 is released and through the tension of the spring 48, the friction rollers 28 and 29 are brought back into contact with similar radial movement to the throws 55 For maintaining the stacked sheets of material in exact alignment during the operation of the feed mechanism, auxiliary means or pins 50 j, and 51 are provided upon the same centers as the pressure rollers 28 and 29 so as to align with the apertures provided. Each of the pin means 50 or 51 are mounted upon spring fingers 52 secured at the end thereof to the underside of the writing plate 12. For the purpose of disengaging the pins 50 and 51, from the apertures in the material and Withdrawing them from projecting through the writing plate 12, I have provided'the cross shaft 54, having its ends journaled in the opposite side walls 20 and 21 of the casing and provided with crank throws 55 and 56 inserted between eachspring member 52 and the underside of. the plate 14. The shaft 54 is further bended to provide a throw 57 at right angles to each of the throws 55 and 56' into which the connecting rod 58 is adapted to be secured having its opposite end fixed on pivot bracket 41. Any radial movement of the, pivot bracket 41 from the vertical position shown in Figure 11, for the purpose of disengaging the pressure rolls 28 and 29 from contacting with the material, likewise operates the crank throw 57 to impart a and 56 acting to disengage the pins 50 and 51 from the material and to lower them beneath the plane of the writing surface 12. Thelast describedoperation is illustrated in Figure 12 so that upon returning the mechanism to its normal position in Figure 11, the pins 50 and 51 are forced upwardly against the underside of the sheets of ma terial to allow registry with the apertures in the'material when the same come into 10 alignment therewith.
