Figure 6 is a fragmentary sectional detail of Referring more specifically to the drawings:

, My new and improved paper and magazine vending machine consists of a cabinet J. Lo-

cated within the cabinet adjacent, its top is a transverse bridge or framework 2. One of its ends is secured to the rear 3 of the cabinet at 4, while its opposite end is secured to, the front of the cabinet 5 at 6.

Mounted vertically within the cabinet is a worm shaft 1, its lower end being journalled" within a bearing 8, while its upper end is journalled within the bearing 9 fixedly secured withinthe bridge or frame 2 at It, referring to Figures 3 and 4. A paper or. magazine shelf II is threadablymounted to the worm shaft 1 by way of the elongated internally threaded sleeve l2, which."

forms part of the shelf II, the shelf being reenforced to the sleeve by way of the gusset plate l3. The weight of the shelf H and the papers or magazines I4 is supported by the cable l5, which is fixedly secured to the shelf at 15 at one of its The opposite end l8 of the said cable is wrapped about the cable drum 19., The cable drum I 9 is rotatably mounted on the shaft 20 which is journalled withinv the housing 2l,-the said housing 2 housing the spiral spring 22. The spiral spring 22 hasone of its ends connected to the shaft 20 at 23 in the usualmanner, and its opposite end secured to the housing 2| at 24. I r

A pawl 25 is fixedly secured to the shaft 2|] by way of the crank 26. This pawl engages the ratchet wheel 21 which forms part of the cablev drum I9. A crank 28 is fixedly secured to the shaft 20 and when revolved in one direction will wind the spring 22. When the handle 28 is released the pawl 25 will engage the ratchet wheel the guides associated with the paper moving shoe,

21 tending to wind the cable l5 upon the drum lifting the platform II. The amount of lift will depend upon how tightly the spring 22 is wound against the pull on the cable. The pull on the cable is suflicient to raise the platform I l and the papers I. I

By using a reel as shown in Figures 2 and 3, as

the platform is pulled up by the reel the tension 28, the desired balance may be maintained, in-

on the spring within the reel will decrease, at the same time the platform raises the load of papers on the same will be reduced,'therefore an automatic balance is maintained regarding the platform H and the reel and for the various weights of papers or magazines by the tightening.

or loosening of the spring 22 by way of the crank suring smooth operation of the machine.

" OFFICE The platform II is permittedto raise by way of the pull of the cable |5 by the worm shaft I in the following manner. Fixedly secured to the top of the 's'haft is a ratchet wheel 29. Referring to Figures 3 and 4 a pawl 30 is formed on one end of a bifurcated bar 3|. The bar 3| is pivotally mounted to the bracket 32 forming part of the frame 2 at 33. Located on each of its bifurcated ends. 34 are rollers 35. These rollers are adapted to ride upon the pile of papers l4.

When the paper is vended the rollers 35 will drop down to the next level. This will unlock the pawl 30 from the ratchet wheel 29 permitting the worm shaft I to be revolved by the upward pressure of the tubular sleeve l2 through the action of the pull on the cable l5 by the cable drum Hi. This action may take place when one or more papers are vended, but as the pile of papers rise, the bifurcated bar 3| is raised bringing the pawl 30 into engagement with the ratchet wheel 29 stopping the rotation of the worm shaft 1 and preventing the upward movement of the platform II and its load of papers. The papers are guided by the

vertical guide rods

36 and 31. Referring to Figure 3, the guide rods 31 are adjusted to permit the top paper 33 to clear the same, but the guide rods 36 may move on up embracing all of the papers. All of the said guide rods are adjustable over the bottom of the cabinet so they can be adapted to various sizes of papers or magazines being vended.

I will now describe the actual dispensing or vending of a paper. A shoe 33, referring to Figures 3 and 5, is slidably operated within the frame 2. This shoe is guided therein by the upwardly extending legs 40, which form a part thereof. The said legs have rollers 4| journalled to their upper ends and operating within guideways 42 associated with the bridge 2. A connecting rod 43 is iournalled to the legs 40 by the wrist pin 44 at its one end and pivotally connected to the lever 45 at 45 to its opposite end. The lever 45 forms part of a gear 41 which is journalled to the upwardly extending brackets 48 forming part of the bridge 2. These brackets may also be connected to the case I, referring to Figures 3, 4 and 7.

The arm 45 is rotated by the gear 41 in the following manner. A shaft 49 is journalled within the bracket 48 at its one end and passes through the coin actuator box mechanism 50 at its opposite end, and out through the side 5| of the cabinet I terminating in a crank 52. Fixedly secured to its opposite end is a crank 53 and rotatably mounted to the shaft is a gear 54. A pawl 55 is pivotally connected to the lever 53 at 56 and is forced towards the teeth 51 by a spring 58.

I will now describe the operation of the movement of the shoe 39. Referring to Figure 3, the shoe is located as shown, having moved the top paper 38 towards the rear of the cabinet and from under the lip 59. The lip 59 being located transversely of the cabinet and adjacent the slotted opening 60. An upper transverse lip 5| is pivotally mounted to the brackets 52 at 53. This lip prevents access to the paper through the slot 50 when the machine is in the position as indicated. The edge 62A of the said lip resting within the offset 53A of the lip 59 when in the inoperative position indicated in Figure 3. The offset 83A prevents raising the lip 6| from any outside object.

In order to vend the paper or magazine, the shoe 3! is moved from the position shown in Figure 3 towards the front of the cabinet or slot 60, Figure 6, pulling the paper 38 with it by the action of the sharp points 64, referring to Figure 5, or by any other suitable frictional facing secured to the bottom of the shoe. In order to pull the shoe forward a coin is inserted by way of the coin slot 65, causing the mechanism within the coin box 53 to permit the rotation of the shaft 49 when the lever 52 is pulled towards the operator. This will cause the crank 53 to rotate the pawl 55 and the idler gear wheel 54, rotating the gear 41 and the arm 45 in the direction of the arrow. This will move the rollers 4| associated with the legs 40 of the shoe 39 along the guideways 66 and over the spring 51. The spring 61 will force the rollers 4| up into the inclined guideways 68 on reaching the end of the guideways 66.

A cable 69 is secured at its one end to the spring 10 and trained about the idler pulley I I, having its opposite end connected to the shoe at 12. At the time that the roller 4| entered the inclined slot 68 the pawl 55 was released from the teeth 51 of the gear 54 by the action of the arm 13 of the pawl striking the pin 14, the said pin being mounted to the framework of the machine, therefore due to the pull of the spring 10 on the cable 69, the shoe will be returned to the position shown in Figure 3.

The guide roller 4| travels along the guideway 15 and down through the diagonal guide way 16 through the spring guide I1 into the original guide way 66. When the guide roller passes out of the inclined guide way 16 the shoe 39 engages the top paper and as the shoe is pulled to the right along the horizontal guideway 56 the paper will be moved to the position indicated in Figure 3 ready to be vended.

In order to prevent the lever 52 returning to its starting position before the shoe has been moved its full travel in vending the paper, a ratchet pawl 18 is pivotally mounted to the framework at 19, and is adapted to engage the ratchet teeth 80, which are formed on the hub 8| of the crank 53.

When the pawl 55 was released from the teeth 51 of the gear 54, this gear as well as the crank arm 45 was returned to the position shown in Figure 3 as above described. A stop 82 forming part of the arm 45 engages the arm 83 of the pawl 18 disconnecting the same from the teeth permitting the handle 52 to return to its starting position by the action of the spring 84, referring to Figure 4.

Although certain specific embodiments of the invention have been shown and described, it is obvious that many modifications thereof are possible. The invention, therefore, is not to be restricted except in so far as is necessitated by the prior art and by the spirit of the appended claims.
