CHARLES S. BATDORF, OF BROOKLYN, NEW YORK, ASSIGNOR TO AUTOMATIC COIN- WRAPPING MACHINE COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

1 '0 all. whom it may concern:

Be it known that I, CHARLES S. BATDORF, a citizen of the United States, residing at Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Automatic Stop Mechanism, of which the following is a full, clear, and eXact description.

My invention relates to improvements in automatic stop mechanism which is adapted to be used with machines for assembling and wrapping small articles of metal such as coins, buttons and the like, and is particularly, but not exclusively, adapted for use with machines for assembling and wrapping coins such as that described in my copending application Serial No. 331,850, filed August 2-1, 1906.

One object of the invention is to provide means for automatically stopping the operation of the machine should any of the articles become displaced as by the breaking of a stack and scattering of the articles composing the same, or by failure of the stacking means to operate properly, due to the feeding of an insufficient number of articles to the stacking mechanism, or under any other circumstances when the articles operated upon drop beneath the machine.

A further object of my invention is to provide means for automatically stopping the operation of the machine when the coins or other articles are improperly fed to it or become banked up in the feeding mechanism thereof.

To these ends the invention contemplates suitable electrical contacts mounted beneath or adjacent the operative parts of the machine whereby, when the coins are improperly handled or fed, a circuit will be completed and the stop mechanism will be thereby brought into operation.

In the embodiment of my invention herein selected for illustration, the automatic stop mechanism to accomplish the first object comprises broadly certain electrical contacts and connections which will be rendered operative to stop the machine when a coin or other metallic article is dropped to the bottom of the machine to which the mechanism is attached and comes in contact with said connections.

In the drawings, which illustrate a preferred embodiment of my invention, Figure 1 shows a plan view of the main contact Specification of Letters Patent.

and feed chute contact members and a diagrammatic arrangement of the electrical connections used in conjunction therewith. Fig. 2 shows a side elevation of a coin stacking and wrapping machine with the invention attached thereto.

In the drawings, Fig. 1, 1 indicates the contact carrying member proper, which may be composed of a sheet of leather or other suitable material of suflicient size to underlie preferably the entire body portion of the machine with which it is used, said member having supports 2 by which it may be supported beneath the machine, as for example in the manner of a tray or apron. Upon the upper surface of the member 1, two contact circuit wires of opposite polarity 5 and 6 are suitably secured by any suitable means. The terminals of the con tact wires 5 and 6 are secured to binding posts 7 and 8 respectively, preferably upon the margin of the sheet. The contact wires 5 and 6 traverse the breadth of the sheet in alternate transverse loops as indicated in Fig. 1, the transverse lengths of the wire 5 alternating with those of the wire 6, and said loops are effectually insulated from each other. By following out the paths of wires 5 and 6, it will be found that they terminate in the open ends 9 and 10 respectively at the opposite side of the sheet, as

Viewed in Fig. 1, whereby the circuit is nor.

mally maintained open between the wires. The binding post 7 is connected by means of circuit wire 11 with one contact screw 12 of a solenoid 13, while the binding screw 8 is connected by means of circuit wires 14, 15 and 16 with the main circuit wire 24.

Within the solenoid 13 is mounted a slidable metal core 18, which is provided with a stem 19 terminating in the finger piece 20 which extends through the top plate 21 of the solenoid. The core 18 is of such length as to project when in depressed position, as shown in Fig. 1, below the coil of the solenoid and between and in contact with the spring contact strips 22 and 23 respectively in the circuit of the motor 27 which opor ates the machine 4: and said core is so held, as by friction, that it will remain either in the lower or upper position unless in fluenced to change its position. The contact strip 22 is connected by means of circuit wire 2 1 with a suitable source of electricity conventionally indicated as a battery 25 and by a circuit wire 26 with a motor 27 from which power is derived to operate the ma chine with which the stop mechanism of my invention is to be used. Said strip 22 is also connected with contact screw 17. The opposite contact strip 23 is connected by circuit wire 28 with the motor 27.

The operation of the mechanism thus far described is as follows: lVith the contact apron 1 secured in proper position beneath the body of the machine 4, as indicated in Fig. 2, the machine is started inoperation through the motor 27, it being understood that the core 18 of the solenoid has been depressed by manually pressing upon the stem 19 to bring it into contact with the contact strips 22 and 23 to complete the electrical circuit through the motor 27. If during the operation of the machine, a coin or other article upon which the machine is operating, should fall upon the apron 1 beneath the machine, the circuit from the source of power 25 will at once be completed through the contact wires 5 and 6 and through the solenoid 13, whereupon the solenoid will be excited and the core 18 withdrawn within the same, and from between the contact strips 22 and 23, whereby the circuit from the source of electricity 25 through the motor 27 will be broken and the motor and machine stopped, and simultaneously the circuit through the solenoid will be broken. To again start the machine, it.

will only be necessary to remove the coins or other articles from the contact wires 5 and 6 of apron or tray 1, whereby the so lenoid circuit will be broken and upon again depressing the core 18 the operating circuit of motor 27 will be restored, whereupon the operation of the machine will be resumed.

To accomplish the second object of my invention, namely, the stopping of the machine through improper feeding or banking up of the articles to be fed to the machine, I provide the electrical terminals 29 and 30 which are mounted preferably within the rear wall 31 of the feed chute 32 (Fig. 2) of the machine, such for example as that illustrated in my copending application No. 331,850 above referred to. These terminals 29 and 30 are suitably insulated from the chute and from each other by the insulating blocks 33 and 34. From terminals 29 Fig. l a circuit wire 35 leads to the wire 11 and thence to contact screw 12 of the solenoid 13, while from electrode 30 a circuit wire 36 leads to circuit wire 15 and thence by circuit wire 16 to circuit wire 24, source of electricity 25, wire 26, motor 27, wire 28, contact strip 23, core 18, contact strip 22, to the opposite binding screw 17 of the solenoid.

WVith the parts arranged for operation as above described, namely, with the core 18 of the solenoid depressed to form electrical and solenoid 13 would serve to excite the solenoid 13 and withdraw its core 18 from between the contact strips 22 and 23 and thereby break the circuit from the source of electricity 25 to the motor 27 and thereby stop the motor and consequently the operation of the main machine. At the same time the circuit through the solenoid will be broken as above described.

\Vhile I have here illustrated and described the preferred embodiment of my invention, it is to be understood that the same may be altered in details and arrange ment of parts without departing from the spirit and scope thereof.
