9 Claims.

This invention relates to an improved delivering means for tickets, receipts and the like after they have been printed and severed. One of the objects of the invention is to provide a movable means interposed between the severing means and the exit opening so that instruments such as knives and screwdrivers may not be inserted through the exit opening into the I path of movement of the severing means. Sometimes'operators-desire to render such a. machine inoperative. With my improved structure they cannot render it inoperative by inserting any tool into the knife or severing mechanism or into other movable parts of the machine. 5 Another object of the invention is to provide a delivering means which will operate in time relation to the printing means, the feeding means and the severing means.

This invention is an improvement on the ap-' plication of Albert S. Wheelbarger and Grover C. Coil, Serial No. 65,532, filed October 29, 1925 and issued May 17, 1932 as Patent No. 1,858,813, to which patent reference is made for a more complete disclosure of the machine as a whole. The subject matter of this invention may, however, be incorporated in any machine designed the like.

Referring more particularly to the drawing, a counter shaft 1 is provided with a manually operated crank 2 and a gear 3 which meshes with and drives a gear 4, which drives a shaft 5 and a disk 6. The disk 6 is in fact a mutilated gear having gear teeth 7 on a portion of its circumference which teeth drive a pinion 8 secured to a shaft 9. The pinion 8 has one short tooth which lies behind the disk 6 so that the two adjacent teeth form a locking engagement with the periphery of the disk 6. The end teeth of the gear teeth 7 are elongated so as to engage the short tooth of the pinion 8, all of which structure is described in detail in the said application No. 65,532.. The pinion 8 drives a pinion to print and issue tickets, coupons, receipts and 10 secured to a shaft 11. The shaft 9 is provided with an impression roller 12 while the shaft 11 is provided with an electroplate 13, between which roller and electroplate the ticket strip 14' passes. The disk 6 is provided with a wrist pin 15 which actuates a pitman 16 attached to a lever 17 by means of a stud 18. w The stud 18 is attached to an oscillating printing carrier 19 fulcrumed on a shaft 20 and provided with platens 21 and 22 and an ink roller 23.

The main drive. shaft 5 is provided with a cam 24 which actuates a bell crank lever 25 pivoted on a shaft 26, which bell crank lever actuatesa' movable knife blade 2'7 which is caused to travel upwardly against a fixed knife blade 28, severing the paper strip after it has been printed.

The main shaft 5 is also provided with two cams 29 which engage the fingers 30 of a lever 31 pivoted on a shaft 32. A-spring 33 is secured to the shaft 32 and at its other end abuts against a pin 34 on the lever 31, thereby tending to hold the levers 31 in the position shown in Fig. 3.. The levers 31 are connected at their upper ends with a delivering means35 which is rec tangular in vertical cross-section, but whose upper and lower walls converge toward each other at the outer end so as to substantially conform to the sides of the exit opening 36 in the easing 3'7. A spring baffle plate 38 is secured to the lower wall of the delivering means and ex tends upwardly, resiliently pressing againstthe lower surface of the upper wall and thence ex tending slightly downwardly again. A The latter portion of the movable knife 27' is provided with a U-shaped hook 48 which re-- ceives a knob 49 of the bell crank lever 50, pivoted on a pin 51 secured to a plate 52, mounted on a shaft 5 and cross-bar 32. The other end of the bell crank lever 50 is provided with an offset lug 53 which projects into the path of move-Q ment of the cam 54, rigidly secured to the rota"- table shaft 5 and bell crank lever 55 is pivoted on cross-bar 32. One arm of the bell crank lever 55 is provided with a cam surface 56*which is engaged by the said cam 54. The other arm of the bell crank 55 is provided with a cam lug 57 which engages the lower beveled edge 58 of the lug 53. Under the cam 57 is a recess 59 to receive the lug 53, and a second arm'of the bell crank lever 55 terminates in a cam portion 60. The parts are normally in the position shown in Fig. 4, at which time the crank handle 2 has not commenced its rotation. As the crankhandle 2 is rotated, the shaft 5 is rotated thereby. The cam 54 is in engagement with thecam surface 56. As the cam 54 rotates in a counter-clockwise direction, as viewed in Fig. 4, it rotates the bell crank lever 55 in a clockwise direction, so that cam 5'7 engages the lower bevel of the lug 53, rotating the bell crank lever 53 clockwise, and lowering the movable 27. The movable knife is now held in its lowered position by the lug 53 engaging the forward'side of the recess 59. As the cam 5e continues rotation, it engages the cam portion so of the bell crank lever 55, rotating the lever 55 in a counter-clockwise direction, and thereby lower-- ing the forward edge of the recess 5'3 below the lug 53. The cam 54 now engages the log 53, rotating the bell crank lever in a counterclockwise direction, and raising the knife, thereby severing the paper. When the cam 5% has passed the lug 53, it engages for a second time the cam surface 56, rotating the bell crank lever in a clockwise direction, so that the cam 57 again. engages the bevel surface 58 of the lug 53; thereby slightly rotating the bell crank lever 50 in a clockwise direction and lowering the knife into its normal position as shown in Fig. 4.

I the nose of the cam 29 has passed the ii It is necessary to lower the knife last described so that in case the paper 14 has been completely consumed, a new roll could be inserted.v If the movable knife closed the opening betweenthe knife blades, it would be impossible to insert a'- new roll of paper.

Before the agent commences, the operation of the machine the parts are in the position. shown in Fig. 3. In operation the agent rotates the crank 2 clockwise, moving the printing carrier 19-rearwardly so that the ink roller 23 brought beneath the type wheels 39 and the platen 22 isthen moved beneath the type wheels 39 press ing-the paper strip 14 against the same; The gear teeth '7 now engage the teeth of the pinion 8, rotating the pinions 3 and If), feeding the ticket strip forward and impressing thereon the printed matter carried by the electroplate 13, which has'been inked by the ink roller 40. cam 24 thereafter engages the bell crank lever 25- movingthe movable knife plate 27 upwardly, thereby severing the paper. As soon as the operator commences the rotation of the crank 2 thereby rotating the main drive shaft 5 the cam 29 has moved the delivering means 35 from the position shown in Fig. 3 to that shown in 2. The rollers 12 and 13, therefore, feed the ticket strip above the spring baffle 38, and when the knife 27 moves upwardly severing the paper, theticket is securely held between the upper sur face of the spring baflie 38 and the lower surface of the upper plate of the delivering means The upward movement of the knife 27 does not displace the delivering means 35, for a cutaway portion 41- is provided in the rear end of the deliveringmeans which cutaway portion is of a configuration conforming to the shape of the upper part of the knife. Immediately prior to the completion of the operation of the 1' 3D, and the spring 33 now moves the do -J-l'lllfi means from the position shown in Fig. 2 to that shown in Fig. 3, so that the forward end of the delivering means is now exactly adjacent the exit opening 36.

It will-be noted that when the delivering means 35 is in the position shown in 2 it would beimpossible to insert any instrument through theopening 36 and between the knife blades 27 and. 28. It would likewise be impossible in any other position in which the delivering The means 35 might be. I therefore provide an improved delivering means and at the same time provide means to prevent the insertion of an object such as a screwdriver for the purpose of damaging or mutilating the machine.

I realize that many changes may be made in the specific form which I have shown herein without departing from the spirit of this invention. I desire, however, to claim the invention broadly in whatever form it might be embodied which may fairly fall within the terms of the appended claims.
