CURT J. ROI-ILAND, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, TO HOBBS MANUFACTURING COMPANY, A CORPORATION OF MASSACHUSETTS.

AUTOMATIC VENDING-MACHINE Application filed March 21, 1918.

To all whom it may concern:

Be it known that I, Cun'r J. ROHLAND, a subject of the Emperor of Germany, having declared my intention of becoming a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Automatic V ending-Machines, of which the following is a specification.

The essential features of my invention are applicable to automatic vending apparatus generally, although herein shown more particularly as adapted and applied to ticket vending machines, the basic principle involved being the utilization of the solenoid as a means of actuating the several operative parts of vending apparatus irrespective of the use to which the same may be applied.

Incidentally the invention includes certain minor features in the specific construction and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1, represents what may be designated as a front elevation of the apparatus, partly in section, the door of the casing or cabinet be-' ing omitted; Fig. 2, a sectional elevation taken upon plane of line 22 Fig. 1; Fig. 3, a horizontal section tak n upon plane of line 33 Fig. 1; Fig. l, a sectional detail of the feed-actuating solenoid; Fig. 5, a sectional detail of the dash-pot piston of said feed-actuating solenoid; Fig. 6, a top view of the feed mechanism; Fig. 7, a top view of the shear mechanism; Fig. 8, a sectional detail of the solenoid switch; Fig. 9, is a view showing the feed-controlling switches; Fig. 10, a diagram showing the electric circuits. Fig. 10*, is a detail showing the action of the switch plunger; Fig. 11, is a series of diagrams illustrating the operation of the automatic release.

The operative parts are inclosed in a suitable casing A, closed by a door a, having a slot plate a, through which the actuating or purchase coin a is inserted into the conduit a the upper end of which is coincident with the coin slot in the plate a, when the door a, is closed.

The coin a is received at the lower end of the conduit (i by the grooved end Z), of a Specification of Letters Patent.

trip lever Z), (see Fig. 1) pivoted at 79, to a stationary part, the other end Z), of the trip lever Z), being curved upward and resting against a cam 0, on the rock shaft 0, fulcrumed in a stationary support. A hood a", protects the lower end of the conduit a and the trip lever Z). Rigidly secured to the rock shaft 0, is an arm 0 connected by the pitman rod 0 with the plunger or core (Z, of the solenoid D, which latter is connected by the wires 1 and 2 with the main electrical circuit M, a push button or switch 11 being used to close and open the circuit through the solenoid D.

lVhen a coin a descends the conduit a and rests in the grooved end Z), of the trip lever Z), with its upper peripheral edge against the lower edge of the conduit as shown in Fig. 1, if the push button 11 be then pressed inward to include the solenoid D, in the electric circuit, the plunger (Z, will of course be drawn downward, rocking the shaft 0, through the medium of the pitman c and arm 0 and thereby turning the cam 0, so that the lever b, is free to yield to its own weight and that of the coin, which it does sufliciently to release the coin a into a suitable receptacle indicated by W, in Fig. 1. \Vhen the button 11 is released breaking the electric circuit, a retractile spring 0*, connected with the arm 0 returns the lat ter, the cam c, trip lever b, and solenoid plunger d, to their normal positions, shown in Fig. 1.

One end 6* of an electric switch lever e, pivoted at c, to a stationary part, projects between fingers b, on an arm pendent from the trip lever Z), as shown more particularly in Fig. 1. Consequently when the trip lever Z), is rocked as hereinbefore described the point 6 contacts with the point 6 thereby closing the circuit 3l connected with the main circuit M. In the circuit 3-t is interposed the shear-actuating solenoid F, and the switch solenoid G.

The plunger 7', of the shear-actuating solenoid F, is connected by a pitman f, with a swinging V-shaped shear blade f pivoted at f, to a stationary blade f and arranged to act in conjunction therewith to sever individual tickets t, from the strip T. The solenoid F, and the stationary shear blade 7, are mounted on a bracket h, attached to the upright H, the U shaped shear being held pressed firmly against that stationary shear blade F, by a spring f A retractile spring 7, (Figs. 2 and 7) tends constantly 'to draw out the plunger 7', of the solenoid F, and to open the movable shear blade F, the energizing of the solenoid F, drawing the plunger f, inward to effect the shearing action.

The switch solenoid Gr, being in the same circuit with the shear-actuating solenoid F, isexcited simultaneously therewith to raise the switch plunger g, which carries the finger g, protruding through a longitudinal slot 9 in one side of the tubular lining 9 said tube extending into the solenoid G, as well as into its companion or releasing solenoid G, and acting as a guide for the switch plunger g. This construction is shown in Fig. 8.

When the contact between the

points

6 and 6, is broken by the return of the trip lever 79, to its normal position as hereinbefore set forth, the release of the switch plunger 9, causes it to descend until its finger g, rests against the arm m, of the switch m, causing the arm m of the latter to contact with the point 2', against the resistance of the retractile spring m, as shown in Fig. 10 This closes the circuit 56M, and throws the feed-actuating solenoid 1, into action.

The plunger 2', of the feedactuating solenoid is pivotally connected by a rod 2' with an arm 21*, loosely fulcrumed on a shaft 2", mounted in a bearing h, on a bracket if, on the standard H. The arm 71 carries a pawl i engaging with a ratchet wheel a" rigidly attached to the shaft i as are also the disks 2' the serrated peripheries of which engage with the ticket strip T, to feed the same downward. A bearing roller j, mounted upon a bracket j, attached to the feed channel plate or member K, (in turn rigidly at tached by brackets 70, 7a, to the standard H) is arranged on the same horizontal plane with the axis of the shaft i, to sustain the ticket strip T, against the action of the feed disks i so that the latter will advance the ticket strip T.

The ticket strip T, is fed from a reel R, over guide rolls 9', 1", and into the channel it" in the guide member or plate K, one edge of the strip being alined against the vertical straight edge is, by a gravity guide rest a, mounted on pivotally supported arms n,n, as shown most clearly in Fig. 1.

Equidistant V-shaped nicks o, are formed in the edges of the strip T, corresponding to the length of the tickets. These notches on one side of the ticket strip are utilized for the purpose of releasing and stopping the mechanism after the desired length of feed has been accomplished. To this end I use a rigid switch arm p, formed with a feeler This arm 79, is pivotally mounted on the face of the channel member K, and is normally held against a stop (Fig. 9) by a retractile spring 9. The feeler 79, protrudes into the path of the ticket strip T, through an opening formed for it in the channel member K, as shown in Fig. 9. On the outer end of the arm 77, is a flexible con tact member 79 Normally the feeler 79, rests in a notch on the inner edge of the ticket strip (that which contacts with the straight edge if, in its passage through the channel) engaging therewith as shown at 00, in Fig. 11. When the feed-actuating solenoid is electrically energized as before stated and the ticket strip T, begins to move under the impulse of the serrated forwarding disks 2' the rear edge of the notch o, forces the feeler p, outward sufficiently (y, Fig. 11) to cause the flexible contact 29 to engage another flexible contact a. This closes the circuit 786M, and insures the electrical energizing of the solenoid I, for, and until the completion of,the feed stroke, as said solenoid I, would otherwise be cut out when the advance of the ticket strip forced the feeler p, entirely out of the notch o, and on to the longitudinal edge of the strip (as at 2, Fig. 1) thereby causing the contact 8, to engage with the contact u, and closing the circuit 7910M, thus energizing the releasing solenoid G, causing it to pull down the switch plunger 9, past the switch arm m, and allowing the retractile spring m to break the contact 2', m and open the circuit 56M, which would of course cut out the solenoid I, were it not for the fact that the circuit 7-86-M, had been established as before stated, to be maintained while the feeler p, is in contact with the longitudinal edge of the ticket strip T, and until said feeler is forced by the spring 9, into a succeeding notch 41, thereby breaking all the contacts 79 su, opening the circuit 786M, and cutting out the feed-actuating solenoid I.

In order to render the action of the feed mechanism sufficiently slow and deliberate to obviate a sudden, precipitate stroke of the ratchet arm 2' &c., when the feed-actuating solenoid I, is energized, which would render the device inoperative, I connect the plunger i, of the solenoid I, with a valve piston 77, extending into a dash pot i on top of the solenoid, as shown more particularly in Figs. 4 and 5, by which means the upward stroke of the plunger 2', rod 2' and arm i is retarded sufficiently to insure smoothness and uniformity of action.

By the use of solenoids, actuating reciprocatory plungers by which the several me chanical operations are efiected and controlled T am enabled to greatly simplify and cheapen automatic vending apparatus,

render the operation thereof more expeditious, and the supervision and adjustment thereof more convenient and economical.
