VENDING DEVICE.

Specification of Letters Patent.

Patented Sept. 18, 1917.

Application filed July 27, 1910. Serial No. 574,187.

To all whom it may concern:

Be it known that I, CHARLES E. BRIDGES, a citizen of the United States, residing at 4537 North Whipple St, Chicago, in the county of Cook and State of Illinois, have invented a new and useful Vending Device, of which the following is a specification.

This invention relates to mechanical vending devices, and has for one of its objects the production of a device which will fulfil all of the requirements of the vending machines in common use, but which can be more cheaply and simply manufactured than many of the vending machines of ordinary form, and which also, by reason of its very simple mechanism, presents a minimum susceptibility to mechanical derangements. Likewise, it is practically impossible for a machine operating upon the principle of the device hereinafter described to make mistakes, which not only impair the usefulness and efficiency of the more complicated machines, but also entail some little expense in their maintenance. A further object of the invention is the production of a device which is neat and attractive in its appearance, and strong and durable in its construction, and which occupies a minimum amount of space upon a wall or counter, or other place where it may be used.

A vending device embodying the principles of the present invention is hereinafter described, and pointed out in'the appended claims, and is illustrated in the accompanying drawings, in which:

Figure 1 is a view in front elevation showing the arrangement of the interior parts of the device, a part of the housing for such parts being removed for such purpose.

'Fig. 2 is a view showing the device in transverse vertical section, said section being taken on line 22 of Fig. 1.

Fig. 3 is a transverse vertical section through a portion of the device, being taken on the line 33 of Fig. 1.

Fig. 4 is a similar view, being taken on theline 44 of Fig. 1.

Fig. 5 is a partial longitudinal section, showing a modified form of the device.

Fig.- 6 is a section on line 66 of Fig. 5.

Fig. 7 is a detached view. in elevation of one of the parts shown in Fig. 5.

As shown in said drawings, the device present invention, as pointed out in the appended claims, said case may assume various forms, and the feeding mechanism is also capable of wide variation, but as here shown, said case consists of a rectangular sided box or housing, 10, conveniently made of sheet metal, comprising a back Wall 14, and side walls, 18 and 20 respectively, which are mounted upon a wooden base, 21.

The housing is completed by a removable cover, 22, which is bent to form integral top and front Walls, 23 and 24} respectively. Said front wall, 24, is cut away at its lower margin through substantially its entire width to form an opening, 25, through which the articles are delivered. Secured to said wall, 24, and arranged parallel therewith is a low inner wall 26, which protects the interior of the device fro-m implements which might be inserted through the slot, 25, and also, together with the wall, 24, forms a trough into which the articles are dropped, to be delivered through the opening 25. Said wall 26 is bent to form integral end walls, of which one is shown at 27, said end walls being bent over and riveted to the front wall, as shown at 28. Said inner Wall, 26, engages with a long triangular strip of wood, 29, by means of which its lower end, as well as the lower portion of the front wall, is held in place. Said triangular strip also facilitates delivery of the articles through the opening 25, by causing them to slide forward. The upper portion of the front wall, 24, is held in place by a. lock, 32, having a bolt 33, which engages with a crossbar 34, which is bent over at its ends and riveted to the side walls 18 and 20 of the casing, as shown at 35. By these' means the cover is secured against removal except upon disengaging the bolt, 33, by unlocking the look. In the upper part. of the front wall, 24, is an opening covered b a pane of glass 36,

through which the interior of the device may a time, from the tubes and delivering thenr into the delivery trough above described. Sald tubes as here shown are adapted to contam small boxes of safety matches of tamiliar form, and each tube is therefore rec tangular 1n horizontal cross section. Each comprises a back wall 12, and integral side walls 13, -13 which latter are bent toward each other at their forward margins to form vertical front flanges, 11, 11. Through the slot or opening formed between such flanges, 11. the contents of the tube may be observed. The four tubes '10 are secured to substantially vertical plates. 18. and 19, the former being bent horizontally backward and again vertically upward, and at its upper margin into the form of a hook, 50, as viewed in transverse vertical section (Fig. '2) to engage with the upper edge of the rear wall 11 of the casing, and thus support the tubes.

The plate 19 is bent horizontally backward, and then vertically downward to form a tongue, 51, engaging with a narrow slot, 52, formed by a plate 53, secured to the wall 1-1, and to the base board 21 said plate being bent at its upper margin away from the wall 1-1 in order to form such slot.

Referring now more particularly to the construction of each tube 10, each of the side walls 13, 13, is bent horizontally toward its' mate at its lower end', forming horizontal flanges, 51, 51, which support the weight of the columns of articles in the tubes. The front flanges. 11, 11 are cut off at their lower ends for a distance a little more than the-- vertical dimension of one of the articles, as seen at 56 (Fig. 2), wherebythe bottom article in each tube may be pushed forward beneath such flanges l1, and out of the tube. They are yieldingly restrained from being so pushed forward by means of four coiled springs, 5T. 5T, projecting downward from a horizontal bar, 58, secured to the lower portions of the flanges, 11. These springs are bent forward when the bottom articles are pushed forward by the vending mechanism, in the normal operation of the device, but have sufficient rigidity to restrain the bottom articles from sliding forward if the dc vice is upset or shaken.

'In the form of the device illustrated in Figs 1 to i'inclusive, the vending mechanism by means of which the bottom article in each tube is successively )ushed forward out of the tube and into the delivery trough comprises in general a horizontal rotativeblock. 60, carrying four pushing devicesor knock-outs 61. 61, which actin succession upon the bottom article of one tube after an other, together with coin-controlled means for rotating said block one-quarter turn at each operation of the device. Said block, 60,

tatively, in the side walls 18 and 20 of the.

casing 10. To each of the four faces of said block 60 is secured one of the pushing devices (31, the latter comprising flat strips or arms which, in the rotation of the block, project radially into the lower end of each tube in succession, and engage with the bottom article therein to push it forward. In order to permit of the arms 61 thus entering the tubes, the back walls 12 are recessed at their lower ends, as shown at 61, 61, in Fig. 1, where for convenience two of the tubes are shown emptied of their articles. Flat springs 66, 66 engage with the flatfaces of the block 60, acting as spring detents to cause said block to advance an even quarter turn at each operation of the device, and to remain in the correct angular position until a subsequent ope 'ation, I

r The means for rotating the block 60 comprise four horizontal pins, 70, 70, projecting from one end of said block and arranged concentrically in a circle at equal angular mtervals about said shaft. 63: and a radial slot '2 in said shaft, which slot is'adapted to receive a coin 73 (Fig. 2).

engage withone of the pins and rotate the block with the shaft. The shaft may be thus rotated by means of a wheel or handle, 75, fixed to one of its ends,-which projects through the side wall 20. Means are pro- A coin so" placed \Vlll, 1n the forward rotation of the shaft as indicated by the arrow in Fig. '2,

a vertical stop 82, rising from the base '21, g

and limit further rotation of the shaft, while the downward'pull of the weight will act to restore the shaft 63 to its original position. upon the handle 75 being released.

1 Coins are introduced into the device through a slot 90, in the front wall 21 of the device, whence they pass through a diagonal chute 91. secured to the wall 20, and fall into'the. slot 72. The slot 90 is made of such proportions as to admit the desired coin. The chute Sl -consists of a piece of sheet metal bent to form three sides of a rectangular tube. the fourth side being formed by the wall '20. The top wall of said chute is bent outward at its upperend, as

shown at 9'2. in order to facilitate the entrance of coins'thereinto.

The operation of thedevlce Is as follows:

It being assumed that-articles to be vended have been placed ,in the tubes 10, 10, the operator inserts a com into the chute 91, whence it slides downward into the slot 72,

which, through the action of the weight 80,- 'is normally retained in the position shown a quarter of a turn, the springs 66 will act to quickly rotate it the further distance required to complete a quarter turn, releasing the pin from engagement with the coin, and since in this position the radial slot 72 will .be in such angular position as to open substantially vertically downward, the coin will fall out and into the bottom of the case '10. Further rotation of the block is thereby prevented, and upon the wheel 75 being released, the shaft 63, through the influence of the weight 80, will return to its original position with the slot 72 ready to receive another coin. It is evident that successive operations of the device will displace one article at a time from one tube after another until all of the articles are vended, when the removable cover to-the case 10 may be removed, the coins collected, and more articles placed in the tubes.

Within the spirit of the present invention,

the parts may be otherwise proportioned and otherwise arranged; as for example, there may be a greater or smaller number of the tubes, 40, than are here shown-it being evident that in such case there would be a corresponding number of arms on the block 60, and that the latter would be arranged to rotateat each operation through the distance necessary for-one of the arms to remove one of' the articles from one of the tubes. The number of these partswould also probably be so chosen that upon a complete revolution of the block 60at least one article would have been removed from each tube, so that all the tubes would be emptied at about the same time and there would be no idle movement-of the block until the last article had been vended.

It is evident also that the device may be easily adapted to vend more than one article at each operation, as for example, two, or three, or more articles for each coin introduced. In such case, a correspondingly larger number of pushing devices, or arms,

- is placed upon .the rotating block 60, so that at. each. movement two or more of the arms may engage with the articles in the tubes and push them into the delivery trough 27. Thus, for example, the. device here illustrated may be provided with eight arms-instead of four, so that at each operation one article may be removed from each of two tubes, or a device with six vendin tubes might be provided with twelve or eighteen a horizontal cylindric arms, arranged to vend two or three articles at each operation; and other combinations might be used.

In the modified form of the deviceillustrated in Figs. 5 to 7 inclusive, the rotatlve block 60 is replaced by a similar block 90,

which is rigidly secured at one end to a short shaft 91 supported in a bearing 92 at the upper end ofa post or standard 93. As here shown, the shaft 91 is inserted into an opening at the end of the block 90, and secured by means of a pin 94:- passlng through openings in such parts.- The other 7 end of said block is similarly supported in a bearing not shown. 100 indicates a short rotative shaft, a portion of which 101 1s reduced'in diameter and has a bearing in a tubular -member 102 provided with an. integral flange 103 which. is attached to the wall 20 by means pf screws 104 and 105. To the outer end of saidshaft 100, which passes through the wall 20 is attached a crank 106 with a handle 107, by means of which said shaft may be rotated. The ends of said shafts 91 and 100 which are adjacent to each other are each diametrically slotted as best shown in Fig. 5. The slot in the shaft 91 passes entirely through said shaft, but the slot in the shaft 100 does not extend the entire length of'a diameter, being formed with a curved bottom wall 110. '112 ind1- cates a curved chute leading from an opening 113 in said wall 20 to a point above sald adjacent ends of the shafts 91 and 100. By this means, when the two shafts are arranged as shown, with the slots opening upward, a coin 114 may be introduced into the two slots, and may rest upon the bottom wall 110, whereupon, by reason of its engagement with the two shafts, rotation of the shaft 100 will impart rotation to the shaft 91 and the block 90. The lower end of the chute 112 is pressed into the form of ard 115, surrounding the adjacent ends 0 .thetwo shafts and open upon its lower side, as shown at 116 in Fig.- 6, the purpose of which guard is to retain the coin in position in the two shafts until they. have been rotated through approximately 180, when the coin is permitted to drop out into the bottom of the case 10. The coin-chute 112 is secured to the standard. 93 by screws or bolts 112" or otherwise. Flat springs, not here shown but similar to the springs 66 shown in F i s. 1, 2, and 4, engage with corresponding at faces, or cam faces, upon the block 90 in order toquicklv rotate it through the necessary distance in each case to complete a rotation of 180, after the shaft 102 has been rotated through the greater. part of such distance, whereby the frictional engagement of the coin with the'two slots is lost and the coin allowed to drop out. It w ll be seen therefore that at each operation the block 90 is rotated through 180 and is then yieldinglv restrained in one of its two positions with the slot through the shaft 91 arranged vertically as shown. The shaft '100 is limited in its rotation by the engagement of the crank 106 with the screw 104 which is extended through the wall 20 to form a stop; and also by its engagement with another similar stop not shown, said two stops being arranged to permit the crank 106 to be rotated approximately only 180 in each direction in order to prevent any one from rotating the crank continuously in one direction so rapidly as to retain the coin in the two slots by its frictional engagement therewith, and thus permit more than one operation of the device. Said shaft is returned to its original position upon the release .of said crank, by' means of a coiled spring 120 which surrounds the tubular member 102 and is attached at one end to the screw 105 and at its other end to a screw 121 inserted into said shaft 100. The operation of the device is the same as the operation of'the device shown in Figs. 1 to 4 inclusive, except that upon each operation of the device the block 90 is rotated through 180, instead of through 90, and the number of vending tubes and the number of pushing devices, or arms upon the block 90 are correspondingly arranged to vend the number of articles desired, upon each voperation of the device.
