BURGLAR-ALARM FOR SUIT-CASES, SATCHELS, &c.
T 0 all whom it 'may Concern: p
Be it known that I, ARTHUR T. RU'ruvnN, a citizen of the United States, residing at Toeka, in the county of Shawnee and State of 'ansas, have invented certain new and useful Improvements in` Burglar-Alarms for Suit-Cases, Satchels, &c., of which the following is a specification.
My invention relates to a burglar alarm for suit-cases, satchels, &c., and is arranged togive an alarm the instant the suit-case or lsatchel is picked up from its resting place.
My objectis to prevent unauthorized persons from walking off with suit-cases or sat chels Without sounding an alarm and notifying the owner and others of the fact, and for vantage to travelers who frequently have occasion to leave their property unprotected i in a car or depot for a few minutes.
The invention embodies secret means known to the owner for preventing the alarm from sounding, hence when said means is setthe suit-case may be picked up without sounding the alarm.
In order that the invention may be fully Specification of Letters Patent.
Application led January 14, 1908.
Patented April 27, 1909.
Serial N o. 410,804.
i extends upward through an opening 12 in the bottom of the suit-case and thence over contact point 10, it being held out of engagement with the. same by the weight of thesuitcase when the latter is at rest upon a floor.
13 designates a circuit-breaker in the upper portion of the suit-case and consisting of a brush 14 and a contact point 15. Brush 14 is secured to one end of handle 2 by a link 16, the end of the handle having sufiicient play in its bearing 3 to permit it to move upward far enough to bring brush 14 into con` tact with point 15, when the suit-case 'is lifted. from its resting-place.
17 designates what I term a combinationswitch secured to the top of the suit-case upon a block of insulating material 18. Said co1nbination-switch consists of a holld'w, perforated, rotary knob .19 provided with an annular ilange2`0 at its lower end, a dialv 21 provided with a flange 22 overlapping iian e 20, a segmental contact 23 within the kno and secured to bloclc18, a brush 24 secured to the inside ofthe knob and adapted to engage the segmental contact 23, and a pointer 25 which coperates with the dial 21 in setting the understood, reference will now be made to the accompanying drawing, in which Figure 1 represents a vertical section of a i suit-case provided with my invention, Figs. 1 2 and 3 are sections of a combination-switch i taken on lines H and III, respectively. Fig. 4 is a diagram of the invention. Fig. 5 is a cross section on line V-V of Fig. 1. Fig. 6 isa broken vertical section of a suit-case,
1 designates the suit-case which is of ordinary construction and provided with a handle 2, the ends of which are pivotally arranged in bearings 3, secured to the top of the case.
4 designates an electric bell, or other audible signal, for giving the alarm. This bell is actuated by power from a source of motive force arranged, preferably, in the form Bell 4 is preferablysecured to the outside of thev case, and when so arranged is protected by a shield 6 which is perforated so as not to muftle the soundf the bell.
7 designates a circuit-breaker consisting of a resilient brush 9v` and .a contact point 10. Brush 9 is 4securedto the bottom of the suitcombination at the desired oint.
26 designates a lam pre 'erably of the incandescent style, whic 1 is screwed into block 18 and extends upward into knob 19,
27 designates a push-button for closing a circuit between lamp 26 and battery 5.
The operation is substantially as follows: When the suit-case is placed upon the ioor, or other resting place, its weight will force brush 9 upward out of engagement with contact 10. Knob 19 is then rotated to bring brush 24 into engagement with the Segmente. contact 23. Should the suit-case then'be weight thereof, will immediately spring into engagement with contact 10 and thus automatically close a circuit betweenv battery 5 and bell 4 through ya conductor 28 leading from the battery to the bell, a conductor 29 leading from the bell to contact point 10, a conductor 30 leading from brush 9 to the 'segmental contact 23, and a conductor .31 leading from bru'sh 24 tobattery 5. With the closing of the above circuit, another circuit independent thereof, is simultaneously closed by handle 2 moving upward in its 4.bearing and bringing brush 14 into enga ement with contact 15, so that a circuit will e 'ease by abinding-screw 11, and its free end established from battery 5 to bell 4 through picked up brush 9, `bein(y relieved of thc/a5 conductor 28, thence through conductor 29 to a conductor 32 leading to brush 14, a conductor 33 leading from contact point 15 to conductor 30, thence through the combination-switch 17 to conductor 31 and back to battery 5. When the above circuits are closed the bell will continue to ring until the Jfree end of brush 24 is brought into coincie dence with the opening 34 between the ends oil the segmental contact 32. v This may be easily accomplished through the aid of the dial and the pointer, by anyone familiar with the combination.
Should it be too dark to clearly read the dial, lamp-26 is illuminated by closing the push-button 27 and establishing a circuit between the battery and said lamp through conductor 28, a conductor 35, a conductor 36, and conductor 31. This circuit is independent of the two circuits above described, so that it may be closed before the same preparatory to manipulating the knob 19, through the perforation of which latter the rays of'light will shine from the lamp upon the dial and the pointer. g
In the modified form, Fig. 6, the alarm 4EL is actuatedby-a source of motive power emanating from a mechanical motor 5a, provided with a disk 37 arranged between two brake-shoes 38 39, either of which are adapted to stop the motor. Brake-shoe 38 is actuated by a connecting-rod 40 and a knob 19a, which latter is rovided with a pointer 25a and is rotatab y mounted in a dial 21a. Brake-shoe 39 is actuated by a rod 41 ivotally secured at its upper end to the bra e-shoe and extending down through an opening 12a in the bottom of the suitcase, so that when the latter is placed upon the iioor rod 41 will move upward and force the brake-shoe 39 into frictional engagement with the disk. This locks` the motor until the suit-case is picked up from the floor, when rod 41 drops and disengages the brakeshoe 39 `from disk 37, allowing the motor to actuate the alarm. The alarm continues to sound until the motor is locked by forcing brake-shoe 38 into frictional engagement with the disk, this is accomplished by turning knob 19Eli in the proper direction.
Having thus described my invention, what I claim is 1. In combination with a suit case, having an alarm and an electrical circuit which includes said alarm, means whereby when said suit case is lifted from its support said alarm will be sounded, and means to render said circuit inoperative including a block of insulating material, a dial formed with aglange, a rotary knob having a pointer and an annular flange engaged beneath said first flange and seating on said block, a segmental contact on said block, and a brush on the/knob to engage said contact, said brush and segmental Contact being included in said circuit.
2. In combination with a suit case, an insulating block, a hollow perforated knob rotatably related thereto and carrying a pointer, a dial on the block to coperate with said pointer, a segmental contact on said block, a brush carried by said knob to engage said contact, an alarm, an electrical circuit including said alarm and said knob and contact, and means included in said circuit and arranged on the interior of the knob to illuminate the dial.
3. In combination with a suit case, an alarm, means to sound said alarm upon said case being raised up from its support,.second means to render said iirst means inoperative including a hollow perforated rotatable element, illuminating means on the interior of said hollow element arranged so that the rays from said illuminating means will be projected through the perforations of said element to permit operation thereof, and means to operate said illuminating means independent of said alarm sounding means.
In testimony whereof1 I ax my signature, in the presence of two witnesses.
