2 Claims.

This invention relates to an adjustable paper stop means for accounting machines having a traveling paper carriage and a roller platen, and more particularly to an adjustable paper depth gage adapted for positioning work pieces that are fed downwardly into the carriage from in front of the platen.

The prior art discloses adjustable paper stops which are connected by gearing to insure uniform alignment of a work sheet at any setting of the stops. Such prior stops have been difficult and expensive to manufacture or occupy a disproportionate space on the paper carriage. In one type of the known paper stop members, the iiexible tape is perforated and the unextended portion is wound up on a toothed'wheel. This arrangement is expensive due to the differential spacing of the perforations required in the tape to compensate for the build-up of the tape on the wheel. Another type of paper stop does not require such differential periorations but does utilize a separate and space-occupying container for the unextended portion of tape.

One of the objects of the present invention is to provide an adjustable paper stop means that is adapted for easy assembling in the machine and for quick and easy shifting to various positions laterally therein, without disturbing associated parts or requiring the provision of special component parts.

Another object of the invention is to provide an adjustable paper stop means that is easily operated with a minimum of wear of its component parts.

Still another object of the present invention is to provide suoli a stop means as described that utilizes a minimum of space in the traveling paper carriage.

A further object of the present invention is to provide an adjustable paper stop means that is simple in construction, inexpensive to manufacture, and dependable in operation.

With these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the irnportant elements of which are herein set forth in appended claims, and a preferred embodiment of which is hereinafter described with reference to the drawings which accompany and form part ofthe specication.

The present invention is an improvement over the constructon disclosed in my prior Patent No. 2,204,242, issued June l1, 1940.

Figure l is a partial right side view in vertical section of a carriage for accountng machines embodyng the present invention,

(Cl. IS7- 140) Figure 2 is a sectional detail view of the parts as seen from the line 2-2, Figure l, y

Figures 3 and 4 are detail views showing the general construction of certain of the parts shown in Figure 1 and,

Figure 5 is a sectional detail view as seen from the line 5 5, Figure 1.

Referring to the drawings, the paper carriage consists, generally, of side plates lil supported in spaced relation by means of a frame member I l, and is mounted for lateral movement on antifriction bearings l2 supported in a rail i3 xed to the machine frame partially shown at I4. Rotatably supported in the carriage is a roller platen I5 for supporting work pieces to be printed upon by the usual type bars, not shown. Fixed in the carriage, intermediate the side plates i0, are an angle member 2B and bar 2l, to which is secured a paper table 22. Mounted in spaced relation, laterally in the carriage, on a shaft 23 rotatably supported in the carriage frame member Hare a plurality of frame members 24 carrying feed rollers 25 normally tensioned to bear against the platen l5 by springs 25. Secured to the paper supporting table 22 and to the angle member 20, intermediate the feed rollers 25, are paper delectors 3D.

The feed rollers 25 are shown in the open throat position out of the path of a front fed work sheet S. The sheet S will be inserted downwardly in front of the platen I5, along the deflectors 30 and rearwardly along the paper table 22.

Mounted in the carriage on brackets 3i and in spaced vertical relation with the paper table 22 are a plurality of rear paper deiiectors 32, one in alignment with each of the feed rollers 25, each having a forwardly extending upwardly formed end portion 33 for deflecting the work pieces into the space between paper table 22 and the rear deiiectors 32.

Firmly secured, by means of screws 36, Figure 1, to the bar 2| is a bracket, Figures l, 2 and 3, consisting of side walls 31 connected by a bridging portion 38. The bridging portion 38 is eX- tended rearwardly of the bracket and is bent downwardly and forwardly terminating in two spaced ears 39. Journalled in the side walls 37 is a shaft 4i! having a sleeve 4l rmly secured thereto by means of a set screw 42, Figure 2. Rigidly fixed on the sleeve 4I is a gear 45 supported thereon intermediate flanged discs 45. Gear is positioned in the space between the ears 39 and in a slot 5| provided therefor in the bridging portion 38 of the bracket, enabling the provision of a bracket no larger vertically than the diameter of the gear 45. A exible tape 4l that is perforated for engagement in the teeth of the 'gear d5 lies on the top surface of the paper table 12 and passes partially around gear [i5 between discs llt and the inner surface of bridge t3 and ears Se for movement forwardly and rearwardly upon paper table 22 by rotation of shaft 4U, gear de and discsll by a suitable hand knob (not shown). Affixed to the forward end of the tape 41 is a paper stop member d formed to normally spring upwardly thereon to form a throat for positively receiving the lower edge of the work piece, and to engage the underside of the paper deector 32 which, having angularly formed sides 58, Figure 5, guides the stop (i3 to its adjusted positions.

Usually, in accounting practicegthe work sheets used vary substantially in length. it is obvious, therefore, that when a short form is to be printed on, the paper stop 43 is positioned to the front of the carriage, and when long forms are used stop 48 is to the rear or the carriage. in the rear position of paper stop :lil there is a considerable length of unused tape ll? to be disposed of, The present invention provides a mean-s for retaining the unextended portion of tape il which does not add bulk to the paper stop means, and thereby leaves a maximum amount of space available for associated mechanisms. To taire care of this unextended portion or tape lll, a guide member 53 having holes 5d, Figure fl., is firmly secured to the ears 3S by screws 55, Figure l, and extends forwardly of the carriage to rest on the carriage frame member l. A leaf E5 forming part of the guide member 53 is bent upwardly to overlie the upper surface thereof at a slight distance therefrom. The tape di, passing around approximately 180 of the flanges of discs and between the leaf 5E and guide 53 is moved forwardly and rearwardly in a substantially straight line movement, between the guide 53 and the underside of the paper table 22 as the gear i5 is rotated in either direction, providing a maximum useful life of the tape.

Movement of tape 4l is limited in either direction of its movement to prevent its end from running off of gear 45. The movement is limited in the forward movement of stop 4S by the engagement of the stop 46 with a projection 58 formed in the upper guide S2. In the opposite direction, the movement is limited by engagement of the end 5e of tape 4'! in the junction of the forward end of guide 53 with the lower side of paper table 22.

The above descriptiono a preferred embodiment of the invention is not t0 be taken in a limiting sense as considerable variations are possible in constructions all coming within the scope of the following claims.

What is claimed is:

1. In a machine of the class described, a paper table to support a work sheet, a paper guide adjacent said paper table and forming therewith a channel for said work sheet, a paper stop adjustably positioned within said channel, a flexible tape connected at one end to said paper stop, a second guide member below said paper table and parallel with said paper guide to form with said paper table a lower channel for the free end of said iiexible tape, and rotatable means positively engaged with said tape to retract said paper stop and simultaneousiy force the free end of said flexible tape into said lower channel.

2. In a machine of the class described, a paper table for supporting a work sheet, a channeled paper guide above said paper table, a paper stop in the channel of said paper guide and between said guide and said papel' table, a flexible perforated tape connected to said paper stop, a flanged toothed, wheel engaging said tape and rotatable to adjustably position said paper stop, a casing having a slot in which the teeth of said toothed wheel move to retain said tape in Contact with said wheel, and a second guide connected to said casing, said second guide extending parallel to said channeled paper guide and substantially coextensive therewith but positioned below and spaced from the underside of said paper table to receive the free end of said perforated tape.
