CIRCUIT CLOSER.

Application filed September 27, 1922.

The present invention relates to an alarm especially adapted to be used upon automobiles and the like and has for its principal object to provide an audible alarm electrically operated which will be soundedupon any unauthorized person tampering with the gas control, the clutch or the hood of the automobile, and means are also providedk for placing the alarm in an inoperative position when the automobile is being used by an authorized person Another object ot thev invention is to provide a device of this nature which will be simple and efiicent, easily installed and reliable in operation.

With the foregoing and other objects in view which will appear as .the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter dcscribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed without departing from the spirit of the invention.

Figure 1 is a top plan of the alarm showing the same in its casing, and

Figures 2, 3, and 4: are longitudinal sections through the casing showing the alarm in various positions.

Referring to the drawing in detail it will be seen that 11 designates the casing for housing the alarm which contains the batteries 1 2 and the audible signal 13 in the :form of an ordinary electric bell including the clapper 14. The batteries are connected in series and a lead 15 rextends from one terminal to one terminal of the audible signal 13. `A second lead 16 extends'from the terminal of the other battery to the Contact member 17 which is separated from the contact member 18, and a pivoted bridging member 19 is disposed between the two confacts 17 and 18 and a lead 20 extends from the contact 18 and has connected thereto the wires 2, 4 and 6. A lead 21 extends from the other terminal of the audible signal 13 and has connected thereto the leads 1, 3 and 5. The leads 1 and 2 are connected to a clutch contact which is closed when an attempt is made to use the clutch and may be of any preferred construction. The leads 3 and 4 lead to the gas throttle and are provided with a contact closed upon an attempt being made to open the gas throttle, and

serial No. 590,883.

this contact may be of any conventional construction. The leads 5 and 6 are connected to a hood circuit closer which is closed upon the hood being raised and may be of any preferred construction.

A spring arm 25 is mounted at one end 26 to the bottom of the casing 11 and is curved as at 27 so that the remaining portion extends substantially parallel to the bottom of the casing 11. A catch 28 is mounted in the casing and adapted to engage the other end of the spring arm 25 for holding it out of engagement with an auxiliary spring arm 29 whichv is disposed so as to be normally out of engagement with the contact bracket 30 which is connected to the lead 7, and the auxiliary spring arm 29 is connected to the lead 8 both of which leads are connected to the horn 32. The catch 28 is engageable by the clapper 14 of the bell 13 so that when the bell is actuated the clapper will cause the catch 28 to disengage the end of the spring arm 25 thereby forcing the auxiliary spring arm 29 in engagement with the contact bracket 3() and the horn will be sounded as any suitable source of electrical energy may be disposed in the circuit it not being.

tluught necessary to here disclose this detai A second auxiliary spring arm 35 is mounted in the casing and is normally disposed out ci' engagement with the contact bracket 36. The spring arm 37 is engaged by the lead 1() and the bracket 36 by the lead 9 which form the ignition circuit of the internal combustion engine used in the automobile. When the spring arm 25 is depressed as shown in Fig. 4L it engages the auxiliary spring arm 35 causing it to engage the bracket 36 thereby closing the ignition circuit. The pivoted bridge member 19 has a chain 37 attached thereto which is also connected to the spring arm 25 so that when the bridge member is turned to a position as is shown in Fig. 4, the chain will cause the depression of the spring arm 25 causing it to engage the spring arm 35 and close the ignition circuit. This bridge member is actuated by a rod 38 which in turn is actuated by a key insertable in any suitable locking mechanism 39.

The owner of the automobile, when leaving the same, actuates the bridge member 19 in the position shown in Fig. 3, and should any one tamper with the clutch, gas throttle, or hood of the automobile, a circuit will be closed `for sounding the electric bell 13 as previously explained which will cause the catch 2S to released from the spring' arm therebyv allowing' the spring arm to close the horn circuit. lVhen it is desired by the own-er ot' the automobile to start the engine and place the alarm in an inoperative position, the device is pla-.ced in the position shown to advantage in Fig. y'l which causes the depression ot the spring arm Q5 thereh7 closing the ignition circuit through the spring' arm 35 and bracket 3G.

Having thus described mj; inrention what I claim is l. In an alarm et the class described, an electric bell including a chipper, a springarm having one end fixed, a catch for engagging the free end of the spring ,l arm, and adapted to be moved ont ot engagement therewith by the clapper or the bell, a circuit closer disposed below the spring arm and actuated thereinv when the sprine` arm is lowered, and a manuali;T operatable element for lowering` the spring; arm to place Ithe same in engagement with the catch and to close the circuit closer.

Q. In an alarm, an electric bell. a

clappcr forming a part of the electric bell, a s 1 pi ng arm having one end fixed, a catch engagcable with the other end of tlv spring arm and adapted to be moved out et engagement therewith by the clapper of the bell, a circuit closer disposed above the spring` arm and actuated to a closed position when said spring` arm is releasec, a circuit closer disposed below the springl arm and actuated thereb7 lwhen the spring arni is lowered, and a manuali),v rotatable clement tor lower ingv the spring arm for placing the same in engagement with the catch and to close the second mentioned circuit closer when dcsired.

In combination, a spring arm, a circuit oloser including a pair of spaced contacts, a bridge member piwtall); mounted between the spaced contacts', a Vchain connectinthe bridge member and the spring arnn a second circuit closer disposed below the spring arm and actuated therebyY when the same is lowered hv the bride'e when it is r :"ulcrumed out ot' engagement with its contact.

In testimonv whereof I alti); my signature.
