ALARM-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 451,639, dated May 5, 1891.

Application filed March 17, 1890. Serial No. 344,158. (No model.)

To all w/tom t may concern.-

Beit known that I, MICHAEL A. OD ONN ELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Alarm-Signals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to alarm-signals.

Heretofore in cities having the patrol box and wagon system it has been necessary for an officer after making an arrest to take his prisoner to the nearest patrol-box, and while holding said prisoner with one hand insert his other hand in his pocket for the patrolbox key, with which to open the patrol-box door and'send in the alarm-call, as under the present system an alarm-call cannot be turned in until after the patrol-boX door has been opened. This is objectionable, and often attended with danger, as in numerous instances the prisoner has assaulted the officer and made his escape while the officer was in the act of inserting his hand in his pocket for his patrol-box key. This difficulty I propose to obviate; and the object of my invention is to construct a device to be attached to the outside of the patrol-box that Will,in connection with a policemans club or baton, enable the officer to turn in the alarm-call without opening the patrol-box door; and to this end the nature of my invention consists of constructions and combinations,all as will behereinafter described in the specification, and particularly pointed out in the claims, referings, in which-- Figure l is a sectional View of a patrol-box having my device attached; Fig. 2, a sectional view of a policemans club or baton having an alarm signal or whistle in its handle, by which my device is operated; and Fig. 3, a modification.

A represents the patrol-box, having located therein the usual locked telephone-box B, containing a telephone transmitter h and receiver h', also the ordinary mechanical call device C, with its signal-giving lever D, and a battery-box E, containing cells e for the telephone. To the hook d ou the end of the signal-giving lever D is attached awire F, which passes downwardly and around a roller f, secured tothe battery-box E,then upwardly and connected to a projection or toe g on the end of a shaft G, which is secured in the side of the patrol-box A. The outer end g of this shaft G projects through a countersunk portion a of the patrol-box A, and is of the same configuration as the mouth h of a whistle H, inserted in the upper end or handle of the policemans club or baton I, so that the whistle-mouth can be fitted over said outer end g and made to act as a key or wrench to turn the shaft G, which in turn, through the medium of the wire F, operates the signal-giving lever D to send iu analarm-call at the policestation K.

In cities where alarm whistles or signals of different configuration from that shown in the drawings are in use the outer end g of shaft G would have to be changed accordingly. not fit over the end g of the shaft G.

The operation is as follows: Vhen an officer has made an arrest or desires to call the patrol-wagon, he inserts the handle end of his club or baton in the countersunk portion a of the patrol-box A,` which is sufficiently large to allow the handle to enter, and the mouth 7l., acting as a key or wrench, is fitted over the outer end g of the shaft G. A halfrevolution of the club is then made, which. causes the projection or toe g on the end of shaft G to be raised, thus tightening the wire F and pulling down the signal-giving lever D and sounding the alarm-call at the station K.

In the drawings I have shown an ordinary mechanical call device with my device attached to its signaling-lever; but I lay no claim thereto, as it is obvious that my device can be attached to any form of call device. It is also obvious that instead of the mechanical call device and its signal-giving lever and wire connection an ordinary electric pushbutton signaling device M, having its wire m running through the telephone-box B to the station K, as shown more plainly in Fig. 3, can be attached to the inside of the patrolbox in such position that the projection g on Otherwise the whistle-mouth would IOO the shaft G when revolved will push theliulzton in and complete the circuit, as in ordinary push-buttons, and ring an alarm al: slation K.

That I claim isl. In an alarm-signal, the combination of a club or baton having a signal inserted in iis handle, and a signahoperating shaft of a patrol-box operated by the month ol. said signal, as set forth.

2. In an alarm-signaling device, the combination of a patrol-box, a sig11al-transmitt'ing device with its pull in said patroldnox, a shaft secured in the outside Wall of said patrol-box, mechanism controlled by said shaft for operating the pull, and a policemans club having in its handle a cavity which acts as a key to operate said shaft',substantially as described.
