BURGLAR ALARM SYSTEM Filed July 15. 1931 INVENTOR. TE'VE' n7: HD1705 ATTORNEY Patented June 26, 1934 UNITED STATES PATENT OFFICE sieve James nodes. San Franeheo, can. Application July Is, 19:1, semi m. 550,801 a 1 Claim. (01. 111-414) nected by means of an electrical circuit to a key controlled switch arranged on the keyboard of th cash register or the like. y

In most stores and business'houses a cash register is employed and it is the general practise of burglars to enter the store and demand that the cashier or the person in charge hand over the cash on hand. In this event the cashier naturally has to press a button to open the cash drawer and the register in this case is equipped with a red colored button, which button is connectedlnto'anelectricalcircuitandclomthis circuit when forced inwardly and causes the 5 alarm to be sounded.

The present system is a much more simplified form than that disclosed in my two copending applications for Audible burglar alarms, flied July 15, 1931, Serial Nos. 550,895 and 550,896, respectively, in which I have used an audible alarm in the form of sound reproducing elements and loud speakers, while in the present form I use an audible alarm in the form of a bell combined with a visible alarm.

The principal object of the present invention is to provide a combined audible and visible alarm electrically connected to'a cash register or the likeinsuchmannertbatuponoperationofaselected key of the register an audible and a visible 4o alarmisgivenatapointoutsidethestructure.

Another object of the invention is to provide agreatlysimplifledalarmsystemforstoresand the like which is compact in form, positive in operation and extremely simple in design and costof-manufaicture.

Referring more particularly to the drawing in which one form of my invention is disclosed, the

system consists of an alarm 10 mounted in any suitable place on the outside wall 11 of a build- -'!0 ing structure 12 which in this instance is shown as a store.

The alarm 10 consists of a casing 17 in whichis mounted a ruby lens 18 behind which is mounted a light bulb 19. An ordinary alarm bell mismountedonthecasingl'landthebell 20.90 and the bulb 19 are included in the electrical circuit 16.

Thealarmcircuit 16 isclowdbymeansofthe push button switch 15 which push button is similarineverymannertothekeyboard ofthees register 13 except that it is colored red. The inner end of the push button stem 21 is a plimger type push button and is normally retracted from the contact elements 2201' the circuit 18, but when said plunger is forced inwardly circuit is co .closedandthebell22ofthesignal10isoperated and the bulb 19 is energized which causes the illumination of the ruby lens 18 and the normally invisible letters, Holdup", Holdup in Bank", "Holdup in Store", or Burglar" will be illumi-. as nated and the attention of :v lice directedtothestorewhichisbeingheldup.
