To all whom it may concern:

Be it known that we, CASPAR ME'II'LER, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, and RAYMOND E. FUDGE, a citizen of the United States, residing at West Haven, town of Orange, in said county and State, have invented certain new and useful Improvements in Vending-Machines, of which the following is a specification, reference being had therein to the ac companying drawings.

Our invention relates to new and useful improvements in vending machines for articles of'irregular shape, such as loaves of bread, etc., and has for its object, among other things, to construct such machine of in their operation, and so designed as to be economically constructed and assembled.

To these, and other ends, our invention consists in the vending machine, having-certain details of construction, and combinations of parts, as will be hereinafter described and more particularly pointed out in the'claims.

Referring to the drawings, in which like numerals of reference designate like parts.

in the several figures: Figure 1 is a side elevation of our improved machine with the door partially removed, for the purpose of exhibiting the interior mechanism; Fig. 2 is .a front elevation thereof, partly in section; Fig. 3 is a detailed view of the carrier; Fig; 4 is a view of the upper sprocket wheel with. the mechanism adjacent thereto; Fig. 5 is a view of the parts shown in Fig. 4, looking toward theleft of said figure; Fig. 6 is a view of the lower sprocket wheel with the mechanism adjacent thereto; Fig. 7 is a view thereof looking toward the left of Fi 6;

Fig. 8 is a view of the pawl disk; Flg. 9

is a view of the coinmechanism; and Fi 10 is a view thereof looking toward the left of Fig. 9, with the money box and frame in section.

In the practice of our invention the mechanism is contained withina case 1, that is supported upon a standard 2, fixed in any convenient manner to a base 3, the case 1 having parallel sides with curved upper and lower portions, as shown in Fig. 1. One side of this case is closed by a hinged door 4, and upon the inside, of the case, opposite necessarily, 'metal, and

. relation to each the door, isthe retaining plate 5, to which the brackets 6 and 7 are vfixed, and within which is rotatably mounted the shafts 8 and 9. Upon the shaft 8 are fixed the sprocket Wheels 10 and 11, said latter wheel having laterally projecting pins fixed therein, and upon the shaft 9-are fixed the s rocket wheels 12 and 13, said sprocket w eel- 12 having the laterally projecting pin- 48 therein, all the sprocket wheels being of the same diameter. Connected with said sprocket wheels in the usual manner, is the sprocket chain 14, to which are aflixed a plurality of carriers 15, preferably, but not made ofa singlepiece of sheet formed so as to have base por tions 16, upon which are the retaining fingers 17, and upon one side thereof is the plate 18 to prevent endwise shifting of the contents of the carrier in one direction. We prefer to have the plate 18 upon only one end of the carrier, but it can be constructed on both ends if desired. While we have shown the preferred form of carrier, it is obvious that any form may be substituted to accommodate the article to be contained therein.

Upon one side of the case 1 is fixed a j ournal ,collar 19, within which is rotatable the shank 20 of the lever 21. Fixed uponsaid shank, within the interior of the case, by the pin 22, is the coin disk 23, having a pin 24 fixed therein, projecting laterally therefrom over the edge of the coin wheel 25, loosely mounted 23, between said disk'and the collar 26. In the edgeof this disk is a coin slot 27, and projecting radially from oneedge thereof, is a lug 28 that lies between the stop pin 29 "fixed in the plate 5 and the said pin 24 when the parts are in position to receive, a coin. Projecting across the slot 27, inthe wheel 25, are the coin pins'36, that are so spaced in other thatthe coin of proper denomination will not pass therebetween. Fixed to the lever 21 is a pin 30 that limits the movement thereof when said tacts with the studs 31 and 32 fixedin the journal collar 19. Surrounding the enlarged portion of the shank 20 of the lever 21, is the coil spring 33, one end of which is fixed to the lever 21, and the other end connected with either one of the studs 31 and 32, the action of said spring being such that upon the hub of the disk.

1 pin conit retains the coin disk 23 and coin wheel 25 in the position shown in Figs. 1 and 9, that is, ready toreceive a coin.

The numeral 34 designates the coin chute, which is secured so as to incline downwardly from the coin slot 35, in the case 1, to the point whre'it delivers the coin into the slot 27, the coin channel in said chute being only large enough to admit a coin of proper denomination.

Attached to the plate 5, below the coin wheel 25, is a coin box 37, which is closed at one end by the cover 38, and provided.

with a'slot 39 therein, that is, opposite the slot. 27, and through which the coins tall from the coin Wheel. Pivotally secured to the plate 5-by the. screw 40-is a locking bar 41, having a notch 42 near its upper end. in the path of the pins 45, and a lug 43 upon one side thereof adjacent to the coin wheel 25, the upper end of the lockingbar 41 being steadied by the fixed plate 44. The retaining latch 46 is pivotally secured to the plate 44, and is provided with a notch 47 in one edge thereof that lies also in the path of the pins 45.

Rotatably mounted upon the hub of the sprocket wheel 12 is the pawl disk 49, having a pawl 50 pivotally connected therewith by the screw 51, and normally held by the spring 52, with its-outer end in the path of the pins 48. A link 53 joins the coin wheel 25 with the pawl disk. 49 and forms an operative connection therebetween.

At the lower end of-the case 1 is a discharge opening 55, that iscl'osed by a hinged door 56, and leading therefrom is a'discharge chute 54. The door 56 is locked, when in its closed position, by the locking bar 57, pivotally mounteduponthe. screw 58, with its upper'end in the path of a pin 59 in the pawl disk 49, and the lower end of which is provided with a laterally projecting pin 60 that passes under the retaining hook 61 fixedto the door. 56, as shown in Fig. 1. As the pin 59, during its rotation, strokes the end of the locking bar 57 it imparts a rocking movement thereto and moves the pin 60 from its engagement with the hook 61 and permits the door 56 to drop by gravity. Secured to the pawl disk 49, by-

the pintle 63, is the lever 62, .that slides I against one side of the fixed pin 64, and has a laterally projecting lip v65 upon the lower end thereof, that projects under one edge of the door 56, as shown in Fig. 2. The rotation of the disk 49, with a. coin in the coi wheel, moves the lever 62 from the positio shown in full lines, in Fig. 1, to that shown by dotted lines, so that when the door is released by the actuation of the lever 57 it will open by gravity, assisted by. the weight of the package delivered thereon from the carrier, and the return movement of the pawl disk 49 draws the lever 62 upwardly and preventing the insertion of a 'and the door is raised to its closed position by the contact of the lip 65 with the underside thereof, and when in its closed position the pin 60 will drop under the hook 61.

We have provided. a mechanism for disclosing the fact that the machine is empty, coin in the chute under such circumstances. Thisdevice consists of a rock lever 66, having a downwardly projecting arm 67 thereon and an upwardly projecting arm 68, a plate 69, one face of which is exposed through an opening 70 in'the case, thatis connected with the arm 68 by the link 71, anda pad 73 upon one end of a rod- 72v that is fixed to the link 71.

l/Vhen the machineis loaded, the parts are in the relative positions,- substantially as shown, in Fig. 1, with the lower end of. the

arm 67 held in contact with the contents ofthe lower carrier 74 by the sprin 75, in which positionthe pad -73 is outof t e path of the coin chute, and the plate 69 is in its down position so as not to be readily observed through the opening 70. After the carrier 74 has passed the end of the arm 67 and brought into its discharge position under the sprocket wheels, the spring 75 pulls the link 71 and rock arm 66 upwardly, and the plate 69 is brought to its, position adjacent to the side of the case, and through which the word empty, or similar phrase,

can be readily seen. At the same time, the

pad 73 is moved up so as to close the open end of the coin chute, thus preventing the admission of a coin therein.

In operation, the coin rolls through the coin chute from the opening 70, and drops into the slot 27 of the coin wheel, contacting with the pins 36, as shown in Fig. 9, by broken lines. The operator now grasps the lever21 and moves it about its pivot mounting, at which time the pin 24 contacts with the coin, thereby making a rigid connection between the coin disk, coin wheel, and the coin itself, so that movement of said lever is imparted to the coin wheel. During the first portion of the coin disk rotation,'the outer edge of the coin contacts with the lug 43 on the locking bar 41, moving said locking bar against the tension of the vllt spring 76 to the position shown by broken lines in Fig. 4, wherein the notch 42 is out of the path of the pins 45. At this time the pawl disk 49 is rotated through the link 53, and the pawl 50 thereon rotates the sprocket wheel 12 through its contact with one of the pins 48. This movement is transmitted through the sprocket wheels and shafts Sand 9 to the sprocket chain 14, and the carriers are advanced one step. These steps successively bringing the several carriers into register with the opening 55 in the bottom of the case, at which time the pin 30 inthe lever 21 contacts with the stud 31 into the coin box, I

in the collar- 19. As the entire movement of the lever 21, above described, isagainst the tension of the spring 33, it is immediately returned to its original position when released. The return movement of the pawl disk 49 actuates the levers 57 and 62 so as to close and lock the door 56, as above described. A s the coin box 3 strips the coin from the coin wheel, durin the return movement of said coin wheel, i perchance it does not drop by gravity into-the coin box. A return move ment of the sprocket chain is also prevented by-the retaining latch 46, the notch 47 therein engaging with one of the pins 45 at the completion of each successive advance movement of the sprocket chain. A return movement of thecoin wheel anddisk is'limited by the stop 29, as shown in Fig. 10, in which position that portion of the slot 27 between the pins 36 is again in register with the coin chute.

The device cannot be operated by a coin of any other denomination than that for which the machine is arranged, for if of larger diameter it wi; 1 not enter the chute, and if smaller it will pass between the pins 36, through the coin wheel 27 and slot 39 without operating the machine.

The .door 56 is in itsopen position when, eachof the carriers registers therewith, so that the contents drop therefrom by gravity through the opening 25 into the chute 54, from which they are readily removed.

When the device is used for vending bread, the same is usually wrapped in paper before being placed in the machine, and thus a double precaution sanitary, and being inclosed within an outer case, the bread retains its flavor and freshnessa much longer time than if kept 'in the oven.

There are minor changes and alterations that can be made within our invention, aside from those herein suggested, and wewould therefore have it understood that we do not limit ourselves to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of our invention.
