CI-IEC1--DISPENSING MACHINE.

Specification of Letters Patent.

latented Feb. 8, 1921.

Application filed June 1, 1820. fie-rial No. 385,864.

To all whom it may concern Be it known that 1, DAVID L. hLiUNno, a citizen of the United States of America, and a resident of Newton, in the county of Middlesen' and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Check-Dispensing Machines, of which the following is a specification.

This invention relates to check dispensing machines for use in self-service lunch rooms and has for its object the provision of a simple but elfectlvo device of this character whirh will projet a portion of a check from a check container into position to be seized by a customer and wholly removed, such removal, causing the machine to operate to project a second check into the position formerly maintained by the first check.

The invention consists in an electrically controlled machine which will deliver one check at a time and by such delivery cause the mechanism to be actuated to project another check into position to be seized by the next customer.

The invention further consists in certain novel features of construction and arrangement of parts which will be fully understood by reference to the description of the drawings and to the claims to be hereinafter given.

For the purpose of illustrating the invention, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results although it is to be understood that the various instrumentalities of which. the invention consists can be variously arranged and organized and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described, ezwept as required by the scope of the appended claims.

Of the drawings,

Figure 1 represents a plan of a machine embodying the principles of the present invention.

Fig. 2 represents a side elevation of the same, portions being broken in section.

Fig. 3 represents a vertical section of a portion of the machine on line 3, 3, on Fig. 1, and

Fig. 4 represents a transverse section of the same on line 4, 1, on Fig. 3.

Similar characters indicate like parts throughout the several figures of the drawings.

In the d awings, 10 is a'base of the machine having secured to the upper face thereof, the supports 11 in which is mounted a solenoid 12 having a hollow cylindrical core 13 in which is adapted to be reciprocated a plunger i l having a head 15 at the outer end thereof.

Between the head 15 and one end of the solenoid 12 is a helical spring .16 adapted to normally retain the plunger ll in the position indicated in Figs. 1 and 2 of the drawings.

Secured to the upper ends of the supports 11 are two side plates 17 having superimposed thereon a vertical container 18" in which is positioned a pile of checks 19 such as are used in self service lunch rooms.

The lower check 19 is adapted to be engaged by a pusher 20 secured to a member 21 adapted to be reciprocated upon the rails 22 secured to the inner faces of the side plates 17.

To the lower end of the reciprocating member 21 is pivoted at 23 two link bars 24, the opposite ends of which are pivotally connected at 25 to an arm 26 pivoted at 27 to an car 28 secured to the base 10.

T his arm 26 has pivotally connected thereto midway of its length a link 29 the opposite end of which is pivotally connected to a reduced shank 30 extending axially from the plunger 1%.

There is also pivotally connected to the link bars 2 1 at 25, a yoke 31 having secured to its lower end a rod 32, the lower end of which is threaded to a tubular member 33 the lower end of which has mounted thereon a piston 3a.

This piston 34 is adapted to be moved endwise in a dash pot 35 pivoted at 36 to a bracket 37 secured to the upper fate of the base 10, said bracket preferably having the ear 28 formed thereon.

The member 33 has a passage 38 extending lengthwise thereof from the upper end of which extends a lateral passage 39.

The lower end of the passage 38 is somewhat enlarged and has a ball e0 positioned therein by means of a spring 11.

The ball 40 is adapted to close the passage 38 on the downward stroke of the piston 34 while on the upward stroke of said piston 34 air may be admitted to the dash pot 35 through said passage 38 and lateral passage 39.

During the downward stroke of the piston 34, the air confined within the dash pot 35 beneath the piston 34 will be permitted to slowly escape between the peripl'iery of said piston and the inner wali of said dash pot.

To the front face of the container 18 is secured a bracket 42 having a roller mounted therein, this roller being adapted to contact with the upper face of a check 19 when projected from the container 18.

Beneath the projected check 19 is another roller 44 mounted on and revoluble about the axis of a pin 45 in the short end of a lever 46 pivoted at 47;

The longer arm of the lever 46 is provided at its rear end with a depending weighted projection 48. The lower end of this pro jection 48 is'adapted to contact with a pin 49 extending laterally from an arm 50 formed upon a plate 50 secured to an insulating plate 51 pivoted at 51 to a plate 52 mounted upon supports 52 secured to the base 10.

The pivot pin 51* is insulated from the plate 52 and has secured thereto, an arm'53 having a contact member 53* at the upper end thereof.

This contact member 53 is adapted to engage with a contact member 54 when the arm 53 is moved about its pivot 51* and close the circuit to energize the solenoid 12.

The pivot pin 51 is provided with a binding post 51 connected by means of a wire 56 to a binding post 57 on the base 10 and the contact member 54 is connected by a wire 58 to a'binding post 59 on the solenoid 12.

This solenoid 12 is also provided with a binding post 60 connected by a wire 61 to a binding post 62 on the base 10.

An electric current is adapted to be sup plied to the solenoid from any suitable source through the binding posts 57 and 62.

"One of the link bars 24 is provided with a depending bracket 63 having a rod 64 secured to its lower end on which is mounted adjustable stop members 65 and 66.

When the link bar 24 is moved toward the front of the machine to partially project a check 19 from the container 18, the stop member 66 will engage an extension 67 projecting upwardly from a member 68 pivoted at 69 to one of the supports 52*.

The lower end of the member 68 has a roller 70 mounted therein and coacting with a humped spring 71.

The engagement of the stop member 66 with the extension 67 will move the member 68 about its pivot 69 and the roller 70 slightly over the hump 72 and then permit the roller 7 O to rapidly drop into the depression 73 in said spring 71.

During this operation the extension 67 will engage with the lateral projection 74 on the lower end of the plate 50 thereby causing the member 50 to make a rapid return to its normal position and preventing an are being formed between the contact members 53 and 54.

When the check projector 20 is moved toward the front of the machine and between the rollers 43 and 44, the breaking of the circuit to the solenoid is effected.

When the solenoid 12 is energized, the plunger 14 will be moved in the direction of the arrow a on Fig. 2 of the drawings thereby through the pivoted lever 26, link bars 24 and reciprocating member 21 moving the lower check 19 in the container until it is partially projected from said container and retained between the rolls 43 and 44,

When in this position the circuit will be broken and will permit the spring 16 to return the plunger 14 into the position shown in the drawings and return the reciprocating member to its normal position, but as soon as a customer seizes the projected check 19 and removes it from between the rolls, 43,44, the weight 48 will cause the lever 46 to be moved about its pivot 47 until the rolls 43, 44 come into contact, and the downward move ment of the weighted end 48 will move the switch 53 suiiiciently to bring the contacts 53 and 54 together thereby again completing the electric circuit and repeating the operation.

The movement of the switch 53 about its pivot is limited in either direction by means of the stop pins 74*.

The movement of the extension 67 to the rear of the machine is limited by the stop pin 75,

One of the supports 11 hassecured to the upper end thereof a bracket '76 having a bell. 77 supported thereon.

Pivotally mounted on the extreme end of the bracket 76 is a lever 78 having at its upper end a bell hammer 79. The lever 7 8 at its lower end is provided with a lateral extension 80.

The lever 7 8 is retained in its normal position shown in the drawin s, by means of the spring 81.

Extending upwardly from the link bars 24 is an ear 82 having pivoted at 83 to the upper end thereof, a latch member 84 normally in a vertical position and prevented from moving toward the forward part of the machine by means of a stop pin 85.

When the link bars 24 are moved toward the front of the machine to project a check 19 from the container 18, the latch member 84 will ride over the projection 80 and upon the return movement of the link bars 24 this latch member will engage the projection 80 and move the lever 78 about its pivot a pre determined distance until the said latch member rides over the projection and is disengaged therefrom whereupon the spring 81 will force the hammer 79 into contact with the bell 77 and cause an audible signal to be sounded.

The piston 34 in the dash pot 35 retards the return movement of the various parts of the machine so that these parts assume their normal position without undue or shock.

The mechanism is incased within a cover 86 shown in dotted lines and secured in any suitable manner to the base 10.

The pivot pin 51 is surrounded by a spring 8? the tension of which is adapted to be adjusted by means of the nuts 88. This sprii'ig 87 retains the member 51 in contact with the plate 52 and creates suilicient triction between these two members 51 and 52 to prevent accidental movement of the member 51 about its pivot 51*.

T 1e device is of such a size as to make it possible to position it upon a counter and does not require columns or a special cabinet to support the same.

Ely placing it upon a counter in this manier it at all times within view of the cashier making it possible to prevent a customer from taking more than a single check from the device.

At all times there will be single check partially projected from the container and as one customer removes the projected check the apparatus will immediately be set in operation to partially project another check ready for the next customer.

Each time that a check is removed an audible signal is made and if desired a register oil any well-known construction may be connected to the device to record the number of checks disposed of each day in order that an accurate record may be made of the number ot customers served.

This makes a very simple and effective device for dispensing checks or other tickets.

It is believed that from the ioregoing description, the operation and many advantages of the present invention will be readily understood.
