To all whom t may concern.'

Be 1t known that we, Gnoncn E. PEA-sn and FREDERICK H. Piense citizens of the United a Y States, residing at MountainA vView, 1n the'v county of Santa Clara and State of California, have invented certain new and useful Improvements in Vending lllachines; and we do declare the following to be a full, clear,- and efX-act description of the invention, such as will enable others skilled in the art to which it appertai'n's to make and use the same.

Qur invention relates to improvements in ivending machines and it is our object to provde an exceptionally simple and inexpensive construction, including a new and compact association of parts, for vending lead pencils or any other desired articles, the construction being such? that the operation of the machine is automatic immediately upon insertion of a coin, without the necessity of operating any hand levers or the like, novel provision being made for bringing the entire mechanism to a stand still after one article has been dispense-d thereby.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Figiire 1 is a vertical, longitudinal sectional view through a vending machine constructed in accordance with our invention.

Fig. 2 is a horizontal sectional view'onv line 2-2 of Fig. 1.

Figures 8, l and 5 arevertical transverse sectional views as indicated by lines 3-8, 4 4 and 5 5 of Fig. 1.

In the drawings' above briefly described, the numeral 1 designates a casing which comprises a front 2, a back 3, a top l,- a bottom and two end walls 6 and 7. lVhile this casing may be formed of wood. with its several sections secured together by screws or the like, a metal construction is in most instances preferable. i

Substantially mid-way between the end walls 6 and 7, the casing is divided 'by a vertical transverse partition 8, the space be tween this partition and the end wall `6,- being adapted to vconta-inthe Varticles to be vended, as well as the dispensing means for such articles. This space, in the present showing, is divided by siibstantially horizontal partitioning means, into an upper` compartment M constituting a magazine for vided with an' appropriate door 11 for use Y in filling said magazine with'the articles to be vended, a construction being shown for vending lead pencils P.

The partitioning means'between thev magazine Mend the receiving compartment R, preferably comprises two substantially horizontal though slightly declined boards or plates 12 and 13, having an article-discharge throat 14 between them. Two discs 15 having notches 16V are preferably provided to receive the pencils or the like P, one at a time from theV throat 14, and deliver them to the receiving compartment R, when the horizontal shaft/17 Aupon which said discs are mounted, is rotated to the desired exent. This rotation is eifected by means hereinafter described.

l Between the partition S and the end wall 7, is a second partition 18 rwhich divides this portion of the casing into a switch compartment S and a motor compartment C; The shaft 17 passes across both these compartments, both partitions 8 and 18 having appropriatebearing openings for said shaft.-

Secured to one side of the partition 1S and disposed in the motor compartment C, is a vertical plate 1.9'having its lower'end directed yhorizontally as'v indicated at 2() and then upwardly as at 21,'adjacent the end wall 7 of the casing 1. vThis upwardly turned e'nd'21 of the plate 19, is formed with an opening constituting a' bearing for one end of the Vshaft 17, while the opposite end of this shaft maybe vsupported in the bearing 22 secured to the end wall 6. The

horizontal portion 20 of plate 19 is formed with a bearing opening receiving 'the lower end of a vertical shaft 23 which is directly coupled tok and driven by an electric motor 211 which is disposed in the compartment C', said motor beingsecured to the partition 18 by sere-ws or the like 25. These same screws may well pass through the plate 19 to secure the latter to said partition. i The shaft 23 is provided'fwith a worm 26 meshing with a worm-gear 27 secured on the'shaft 17 ,f' so that'oper'aftion ofY the motor will' rotate the shaft 17 to operate the article dispensing discs 15.

Within the switch compartment S and secured by screws or the like 26a to the partition 18, is a metal coin chute 27 a whose upper end extends through the top 4 of the casing 1, while its lower end terminates slightly above and in laterally spaced relation with the shaft 17. Under this coin chute, a horizontal, preferably channel shaped metal arm 28 is provided, said arm having a spring 29 by means of which it is normally raised to a horizontal position, in readiness to receive a coin deposited in the chute 27a, such avcoin being indicated at 30 in the drawings. In the present showing, the arm 28 is pivoted at 31 between parallel ears 32 which project from a vertical plate 33, the latter being secured to and insulated fromv the partition 8. At 34, a stop pin has been shown extending between the ears 32, to limit the upward movement of the arm 28, under the influence of the spring 29.

The arm 28 and the coin chute 27EL are, by suitable wiring placed in circuit with the motor 24, so'that when a coin is inserted into the chute, it will bridge the gap between said chute and arm, thus completing the circuit of the motor and causing rotation of the latter to operate the article dispensing means.

To downwardly swing the arm 28, free the coin and thus cut olf the supply of current to the motor 24, we have provided a lateral trip arm 35 on the shaft 17. By the time one of the articles has been discharged into the compartment R, the arm 35 strikes the arm 28, swings it downwardly against the action of the spring 29, and discharges the coin into the lower end of the compartment S, which compartment may be provided with an appropriate door 36 for removing the coins, when unlocked.

It will` be understood that any desired wiring may be used. For illustrative purposes however, we have shown one wire 35 electri# cally connected with the plate 33 and con-V sequently in electrical connection with the arm 28, another wire 38 connected to one terminal of the motor 24, and a third wire 39 which leads from the other terminal of said motor, to one of the screws 261 of the coin chute 27a. `The two wires 37 and 38 may well be connected with an ordinary plug 40 adapted to be threaded into an electric light socket.

It will be seen from the foregoing that we have provided an exceptionally simple, inexpensive, compact, efficient, reliable and generally desirable vending machine which will be absolutely automatic in its operation and the arrest of such operation. It is only necessary to insert a coin into the chute 27?, to bring the vending machine into play. This coin completes they electric circuit for the motor 24, causing the latter to rotate shaft 17 and operate the dispensing discs 15 to discharge one article from the throat 14, into the receiving compartment R. By the time this discharge has taken place, the arm 28 is swung downwardly by the trip arm 35, thus releasing the coin and breaking the cir cuit of the motor, leaving the machine in readiness for further operation.

As excellent results have been obtained from the details disclosed, they may well be followed. However, within the scope'of the invention' as claimed, modifications may of course be made.
