' 4 Claims. (01. 194-58) My invention relates to improvementsin vend-- ing machines.

The objects of my invention are to providean eflicient, coin operated vending machine for small packages, of superior simplicity which can be operated without utilizing springs.

I attain these objects by the. means illustrated in the accompanying drawings, in which,-

Figure l is a plan view of my apparatus;

Figure 2 is a front elevation foreshortened;

Figure 3 is a cross-sectional detail on the line 3-3 of Figure 6;

Figure 4 is a longitudinal sectional detail on therline 44 of Figure 6;

Figure 5 is a plan. view showing an alternate form of slide;.

Figure 6 is a bottom view with the bottom plate removed and showing a part of the top plate of the base broken away.

Similar numerals refer to similar parts throughout the several views.

My apparatus comprises a hollow base, 1, which may be of any desired form, having a bottom plate, 2, securedthereto by suitable locking means. The base is provided with a top plate, 3, which may be united to the base by set screws, 3a, or may be cast integral therewith.

In the drawings I have shown the bottom plate provided with a shoulder, 22), which fits into a groove, formed in the lower portion of the housing and thus secures one end of the bottom plate in place.

A look, 2a, is united to the other end of the bottom plate, and the .bolt of the lock is adapted to engage a slot or groove, 1a,'formed in the opposite end of the housing to lock the bottom plate in position. The lock may be operated by a key in the ordinary way or by such other means as may be desired, and various methods of securing the bottom plate may be provided or.

other equivalent forms may be utilized for providing an opening into the coin reservoir which is formed by the interior of the base housing, 1.

Upon the top plate of the base housing I secure aslide housing, 5, for the delivery slide. This slide housing may be formed integralwith the top plate of thebase or maybe secured thereto by set screws, 5a, or other suitable means.

Upon the slide housing I mount the package container or body, 6, whichmay be secured to the slide housing by the set screw, 6a, or other suitable means. The interior --of the body may be so shaped as to conform to the various kinds of packages which it is desired tovend. In the drawings I have shown two cylindrical bores,- 10,

extending vertically of the body, 6, which are adapted to contain smallround tin cans or other fiat,,round receptacles for tablets suchas aspirin, bicarbonate of soda, etc., which it may be desirable to vend in small packages, andI have shown the delivery slide, 14, provided. with two circular seats, 15 and 15a,each of which is adapted to receive and deliver one of the small round cans. v

The delivery slide comprises a rectangular bar, 14, provided with horns, 14a, at the ends, thereof to assist in manipulating it manually. The seats, 15 and 15a, are cut in the bar asdescribed and. the intermediateportion of the bar forms. a seat upon which the cans in either bore may rest when said-portion is in alinement there- .with, it being intended to deliver the merchandise from this machine from opposite ends of the slide, .14. l

Notches, 20, are cut in the lower face of the bar, 14. A locking lever, 23, is=mounted upon a pivot, 21, secured'in bosses, 25, extending downwardly from and formed integral with the top plate, 3, of the base, 1. i

The forward end of the lever, 23, has an upwardly projectingdog, 19, formedintegralatherewith which is adapted to enter either one of the notches, 20, and lock the slide. The rear end of the lever, 23,,has an upwardly projecting lug,

'22, formed thereon which may contact withthe would permit a penny or any coin smaller than a I nickel to pass through between them and drop into the reservoir without actuating the lever, 23. These fingers are positioned directly below the lower end of a coin slot; 12, which is unitedto the" front of the body by a set screw, 121:, or other suitable means and which is provided with acoin opening; 13, in whi h the coins may be inserted. When a coin of the right size isinserted in the machine, it will drop down the slide until it rests upon the upper ends of the fingers, 18. The lever, 23, is so balanced that the rear end thereof will normally be carried downwardly and the dog, 19, will seat in one of the notches, 20,-and lock the slide against movement.

When a coin of the correct denomination is placed in the machine, the coin as it rests upon the fingers, 18, will be of sufficient height to bear upwardly against the top of the housing, 15, and downwardly against the fingers, 18, as the slide, 14, carries the coin to one side and the coin will then force the front end of the lever, 23, downwardly, thereby disengaging the lug, 19, from the notch, 20, and permitting the slide to be pushed in one direction or the other as the case may be, thus carrying one of the packages to be vended, beyond the slide housing where it can be picked up by the purchaser from the seat, 15 or 15a. In order to permit the slide to move sufficiently to cause the coin to depress the unweighted end of the lever, 23, the notches, 20, are elongated as shown in Figure 5.

The slide, 14, has its front face provided'with two slots, 17 and 17a, and the portion, 14b, of the slide intermediate the slots, 17 and 1711, being in line with the coin as it rests upon the fin ers, 1.8, will :carry the coin to one side or the other of the center. Anextended slot, 170, is formed in the top plate, 3, which registers with the slot in the :coin slide, 12, and extends a suflicient distance beyond the fingers, 18, in either direction so that the coins whencarried by the intermediate portion, 15b, beyond the fingers, 18, can drop down wardly into the reservoir formed by the base.

The body, :6, has suitably secured to the top thereof, atop aplate, 7,with a cover plate, 8,'hinged thereto at a'hinge, 9. The top plate, 7, has a hasp, "la, extending upwardly through a :suitable slot in .the cover plate, 8, and'may be locked by a padlock, .11.

.A bracket, 16, is united 'to the top plate, 7, by whichthe-apparatus maybe bolted to a suitable support so as to secure same ,in upright :position.

In the operation of my device, the slide is pushed to either side. The package reservoirs .are then :loaded, and in loading them one of the boxes will drop into the seat in'the delivery slide which happensto be in alinement with one of :the bores.

.Themac'hine .being secured in upright position with the slide, 14, at its limit of travel in one direction, a coin of the required denomination is :dropped intothe coin slide, 12, and lights upon the fingers, 18, the weight, 24, upon the weighted end of the lever being sufiicient'to counterbalance the weight of the .coin and retain thelever, 23, in locked position. As the-slide, '14, is pushed mantually in the opposite direction, the coin bears upwardly against the top of the housing, :5, and downwardly against the arms, 18, of the lever, 23, thus forcing the front end of the lever, 23, .down and releasing the detent, 19, from the notch, '20. As the slide, 14', is then pushed manually transversely of the machinethe charged seat carries the can therein out Where it may bereached by the purchaser. At the same time, the other seat'is carried under its respective bore and one ofthe cans drops into it from that bore. in the slide, 14,is pushed out for the delivery of the can contained therein, the-intermediate portion, 141), carries the coin along with the slide and a: and rear plates of the body, 6, which permit an base, a housing mounted upon the base, a body having a;plurality of vertical bores formed therein mounted upon the housing, a slide seated in the-housing and slidable therein, seats formed in the slide corresponding to the bores and adapted to be respectively aligned in alternation with their corresponding bores, a pair of notches formed in the lower face of the slide, a coin tube united to the body, a lever pivoted in the base having a detent at one end adapted to enter either of the notches in the slide, and a weight at the opposite end, such lever being tiltable in one direction by downward pressure of the coin resting on one end thereof when moved to one side of the middle and in the opposite direction by the weight secured to the opposite end thereof when freed of the coin and means adapted to cause the coin to exert a downward pressure upon the unweighted end of the lever as the slide is moved along its-seat in the housing.

2. A vending machine comprising a hollow'base, a housing mounted upon-the base, a body having a 110 plurality of vertical bores formed therein mounted upon 'thehousing, a slide seated in the housin and slidable therein, seats formed in the slide corresponding to the bores 'andadap'ted to be respectively aligned in alternation with their correi135 sponding bores, a pair of notches formed in :the

.lower face of the slide, 'a coin tube united to the body, a lever pivoted in the base having a detent at one end adapted to enter either of the notches in the slide, a weight at the opposite end, such 2130 lever being tiltable in one direction by the pressure of the coin against the top of the housing and the lever when resting on one end thereof when carried by the slide to either side of the center andin the opposite direction by'the'weight secured to the opposite end thereof when freed of the coin, and means united to the slide to remove a coin from the lever when the slide is movedthrough the limit of its travel.

3. In a vending machine the combination with a hollow base, of a housing mounted upon the base, a body having a plurality-of vertical bores formed therein mounted upon the housing, a slideseated in the housing and slidable therein, seats formed in the slide corresponding to the bores and adapted to be respectively aligned in alternation with their corresponding bores, a pair of elongated notches formed in the lower face of the slide, a coin tube united to the body, a lever pivoted in the base having a detent at 1 40 one end adapted to enter either of the notches in the slide, aweight at. the opposite end, such lever being tiltable in one'direction by the downward pressure of the coin on one end thereof and in the opposite direction by the weight secured to the opposite end thereof when freed of the coin, and means including the conjoint action of the top of the housing and the slide adapted to cause the coin to exert a downward pressure upon the unweighted end of the lever as the slide is moved along its seat in the housing.

4. A vending machine comprising a hollow base, a housing mounted upon the base, a body having a plurality of vertical bores formed therein mounted upon the housing, a slide seated in the housing and slidable therein, seats formed in the slide corresponding to the bores and adapted to be respectively aligned in alternation with their corresponding bores, a pair of notches formed in the lower face of the slide, a coin tube united to the body, a lever pivoted in the base having a detent at one end adapted to enter either of the notches in the slide, a weight at the opposite end, such lever being tiltable in one direction by the pressure 01' the coin against the top of the housing and the lever when resting on one end of the lever, and in the the whole length of the travel of the lateral slots and in alignment therewith.
