1 Claim.

This invention relates to paper carriages for accounting machines, and more particularly to a means-for detachabiy securing certain parts of the front feed paper mechanism to the carriage 5 proper. I

The primary object of the present invention is to provide a clamping means which will hold the front, feed paper guides in operative position on the carriage and which may be readily removedto facilitate the handling of rear fed paper.

With this and incidental objects'in view, the invention consists of certain novel features of construction and tombinations of parts, the essential elements at which are set forth in the ap' pended claim, and a preferred embodiment of which is hereinafter described with reference to the drawings which accompany and form part of the specification.

in the drawings:

Figure 1 is a right side elevation of an accounting machine carriage embodying the invention, 1

Figure '2 isa detailed perspective view of the improved clamping device,

25 Figure 3 is a detailed rear elevation thereof,

and

Figure 4 is a view similar to Figure 1, but showing the front feed guides in adjusted position.

The device is illustrated in connection with the type of carriage disclosed in United States Patent No. 2,060,954, issued to Oscar J. Sundstrand on November 17,1936, and my United States application Serial No. 192,675, flied February 26, 1938, and is an improvement over the clamping mechanism disclosed in the application.

Referring to Figure 1, the carriage is mounted for transverse movement along abed I by suitable roll and groove construction indicated generally at 2. A platen 3 is joumaled at its ends in oppositely disposed side walls, such as 4, and is arranged to be rotated either manually or automatically. The rear fedpaper 5 is inserted downwardly over .a paper table 1 extending across the carriage. The paper then passes! downwardly around the platen between rear feed rolls such asii, and bandssuch as I2, then rearwardly under a plate I, and upwardly out of the car- For introducing front fed sheets, upper and lower guides l5 and i8, respectively, are provided. The lower guides are formed as chutes and serve to guide the paper as it is inserted downwardly therein, and the upper guide is provided with an wardly as the front feed guides l5 and i6 edge guide |I which assists in directing the paper laterally. The upper guides are pivoted on rods such as I3, that extend through the lower guides i6 and are secured to arms such as i9. Arms l9 are in turn secured to arms such as 20, pivoted 6 on semi-cylindrical studs 2|. Arms 20 are held in engagement with studs 2| by studs 22 secured in the carriage side walls. In operation, after the front fed paper is inserted, guides I6 are swung to the right about pivot studsv 2|, this 10 movement also swinging guides i5 to the right. Figure 4 shows the parts in this position,

The upper ends of guides l5 are supported on a rod 23 extending between forwardly extending arms such as M, fixed on the carriage side walls.

From a comparison of Figures 1 and 4, it is apparent that a flexible connection must be provided between guides l5 and rod 23 to allow guides ii to move slightly upwardly and downare moved from one position to another. It is also desirable to swing guides l5 from the position shown in full lines in Figure 1 to the position shown in dot and dash lines in this figure. This greatly facilitates handling of the rear fed paper. 15

To permit the above described movements of guides i5 and to hold the guides in proper position, the following clamping means is provided. U-shaped brackets such as 25 are secured to the rear of guides i5. oppositely disposed and identical clamp members 26' and 21, telescoping one within the other, are pivoted upon a pin 28 which passes through apertures in the bracket 25 and also through apertures 29 (Figure 2) in ears provided on clamp members 26 and 21.

The right ends of the clamp members are beveled inwardly and are provided adjacent the beveled portions with oppositely disposed V- shaped notches 30 of a size to fit neatly around rod 23. A spring 3| (Figure 2), connected between the clamp members, tensions the members toward one another; An upwardly extending projection 32 formed on member 21 and a depending projection 33 similarly formed on member 26 are arranged to bear against the bases of the opposite members to limit the action "of spring 3| and thereby hold the parts in convenient position to receive rod 23.

When the operator desires to remove guides l5 from the position shown in full lines in Figure 1 to the position shown in dot and dash lines therein, it is merely necessary to grasp the guide and give a slight'pull toward the left. This spreads the clamp members 26 and 21 against the tension of springs 3|, disconnecting guides I! from rod 23. After the rear fed paper is handled, guides I! are swung back to the right, toward the full line position shown in Figure 1, the beveled rear edges of the clamp members 26 and 21 guiding the assembly toward rod 23. The operator then exerts a slight pressure toward the right, causing the beveled ends of the members to spread the clamp members apart against the tension of spring 3|, admitting rod 23 to notches 30. The tension of springs II then holds the clamping members and guides l5 against accidental displacement from this position.

Referring now to Figure 3, sleeves such as 34, adjustable along rod 23 by means of thumb screws such as II, are provided to prevent lateral movement of the clamp members and guides I 5. These sleeves are of just sumcient width to fit between the side flanges of clamping members 26 and 21.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarilv stated it is to be understood I 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 terms, all coming within the scope of, the claim which follows.

1 What is' claimed is:

In a paper carriage having a platen, a front feed mechanism including a bail mounted for pivotal movement toward and away from the platen, a paper guide pivoted on the upper portion of the bail, a rod mounted on the frame of the carriage, and a clamping means mounted for a limited pivotal movement on the upper portion of the paper guide and provided with oppositely disposed jaws presenting beveled surfaces to the rod, so that the clamp will engage the rod when the paper guide is moved into paper receiving position.
