PAPER HOLDING MEANS FOR COMPUTING MACHINES Original Filed Dec. 30, 1938 INVEYNTOR WALTER A. ANDERJO/V ATTORNEY I 7 BY Patented Sept. 10, 1940 UNITED srss PAPER HOLDING MEANS FOR COMPUT- ING MACHINES Original application December 30, 1938, Serial No. 248,431. Divided and this application December 29, 1939, Serial No. 311,578

3 Claims.

This invention relates to computing machines, and more particularly to the paper holding apparatus thereof.

This application is a division of my application Serial No. 248,431, filed December 30, 1938.

An object of this invention is to provide the paper carriage of such machines with a tally roll support that is simple in construction and which may be readily adjusted to accommodate varying widths of tally rolls.

With this and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts,the essential elements of which are set forth in appended claims, and a preferred-embodiment of which is hereinafter described with reference to the drawing which accompany and form part of the specification.

In said drawing:

Figure 1 is a top plan view of a paper carriage showing the improved paper holding means, together with the customary roller platen,

Figure 2 is a front elevation thereof, showing also the customary pressure rolls for cooperating with the platen for feeding the paper,

Figure 3 is a right side elevation thereof, and

Figure l is a side elevation of details of the adjusting means for the paper holding means.

The invention is illustrated as applied to a paper carriage of the type commonly used on adding machines, although it is to be understood that its use is not restricted to machines of this character.

The carriage is illustrated as having a base I and side members 2 and 3. A platen d is secured on a platen shaft 1 that is mounted for rotation in sides 2 and 3. A pair of paper feed rollers 13 are mounted in a cradle Id located centrally between sides 2 and 3, and hold the 40 paper against the platen, under the tension of a spring 15 secured at one end to a pin it on the cradle and to a lug IT on the base i. Cradle M is loosely mounted upon a tie rod i8 secured between sides 2 and 3. A paper guide 26 for di- 45 recting the paper from the supply roll to the platen is mounted rearwardly of the platen.

A pair of laterally adjustable tally roll supports 30 are slidably mounted upon two rods 3i and 31 secured rearwardly of paper guide 25. Supports 50 30 are formed at their forward ends with projections 32 which guide the paper as it passes from the tally roll to the platen. The sides of the supports serve as lateral guides for the tally paper during the feeding thereof. The lower forward ends of projections 32 terminate at a sufficient distance to the rear of the platen so that forms such as deposit slips and the like, indicated at H3, may be readily inserted at the rear of the platen.

Cylindrical studs 33 of a size to fit snugly within the tally roll core are riveted to the inner sides of supports 3d for mounting the roll. The snug fit between the studs and the core provides sufficient friction to preclude superfluous unwinding of the paper as it is fed.

Annular grooves 35 are cut in rod 3! at spaced points corresponding to the different widths of tally rolls to be used. Sleeves 34 are slotted on their upper and lower sides as at ts and 3!, re-

spectively, slots 46 being deeper than slots ii, and having their bases flush with the bases of grooves 39 in rod 3 l. U-shaped springs 42 areinserted in the slots 4t and 4!, slot at preferably being peened or otherwise upset against the lower leg of the spring to hold the spring in place, leaving the upper leg thereof free to flex and latch within grooves 38. When changing from a tally roll of one width to one of another, the operator need only pull supports 3i! toward or away from each other, out of their latched engagement with one set of grooves and into engagement with the other set, thus effecting a quick and easy lateral adjustment.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.

What is claimed is:

1. A paper holding apparatus for computing machines including a frame having upstanding side members, a rod extending from one side member to the other, two supports for holding a paper roll, and being slidable on said rod to accommodate rolls of variable widths, spaced recesses in said rod, and yielding means co-acting with said recesses to hold the supports in their adjusted positions.

2. A paper holding apparatus for computing machines including a frame having upstanding side members, two rods extending from one side member to the other, two supports for holding a paper roll, and being slidable on said rods to accommodate rolls of variable widths, spaced recesses in one of said rods, and yielding means coacting with said recesses to hold the supports in their adjusted positions.

3. A paper holding apparatus for computing machines including a frame having upstanding side members, a rod extending from one side member to the other, two supports slidable on the rod for holding paper rolls of different widths, recesses spaced on said rod to correspond to the different widths, sleeves mounted on said supports and having slots, the bases of two of said slots being flush with the bases of the said recesses, and the bases of the other slots being outside the periphery of said rod, and U-shaped springs inserted in the slots and having their 5 legs bearing against the said bases.
