ALARM.

Specification of Letters Patent.

Patented Feb. 8, 1916;

Application filed March 10, 1914. Serial No. 828,815.

To all whom z't may concern: Be it known that I, JOHN J. GREYTAK, citizen of the United States, residing at Great Falls, in the county'of Cascade and State of- Montana, have invented certain new and useful Improvements in Alarms, of which the following is a specification.

This invention relates to an improved audible alarm device for valises, Satchels,

and such like articles. I

The object of the invention is to provide a valise, satchel or other article with an alarm or signal device which will remain quiet or inoperative while the satchel is resting on the floor, table or other supporting structure, but will automatically sound when the valise is raised from its support.

The device is intended for use when the owner desires to set the valise down in a public place and leaveit unattended for a Under such circumstances, if any unauthorized person should raise the valise, to carry it oil, the alarm would sound and the owner thereof warned in time to prevent the contemplated or attempted theft.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the-accompanying drawings, described in the followng specification and then more particularly pointedout in the claim which is appended hereto and forms a part of this applicatlon.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or correspondin parts throughout the seversial views,1and in which 1 igure is a perspective view, part y broken awa of a valise, said valise having the alarm evice arranged therein; Fig. 2

is a fragmentary sectional view illustrating the drawin s, I'des1re to call particular atin detail the construction of one of the circuit breakers employed in connection with the present invention; and Fig. 3 is a similar view, the circuit being closed.

Before proceeding with the description of tention to t e fact that while I have evolved my invention with reference to its applicasignal in the present instance is operated by an electric battery 2, secured to the interior wall of the valise. The circuit wires 3 include in the circuit a suitable hell or buzzer 4 of any well known type, a lock 5,

of the key operated type'and a plurality of circuit breakers designated each, as an entirety by the numeral 6, said circuit break-l ers being disposed, one adjacent each of the four corners of the valise, to extend, in a manner to be hereinafter fully described, through the bottomthereof.

The several circuit breakers 6 bein the same, but one will be described in etail, thevsame comprising acaster 7 havin a stem 8 integral therewith and extending into the interior of the valise throu h an openin 9 in the bottom thereof. Sai stem 8 is en arged as at 10, the enlarged portion thereof frictionally engaging a suitable housing or casing 11 rigid with the valise,

The stem proper 8 operates within an opening 12 of the casing 11 andhas secured thereto as indicatedat 13 a contact plate or element 14, a strip of insulation being inter posed between the said plate and the said stem whereby to break the electric circuit clearly illustrated in Fig. 3 of the draw in s.

igid with the casing 11 at one side there of and in the path of the contact plate 14 is a suitable contact '16, one of the circuit wires 3 being connected thereto. U on the opposite side of the said casing 1 is another contaQ 17, said latter contact bein also in the path of the contact plate 14 an insulated from the said casin for an obvious purpose. One of the sai circuit wires 3 is connected to this, the'said last mentioned. contact thereby providing, upon movement of the plate 14, for the 616.1118

of the electric circuit whereby to sound the bell or buzzer 4.

. The lock mechanism indicated at 5 may be of any suitable key operated type, and in the present instance, is adapted to close the circuit upon the locking of the valise. When unlocked, the circuit-is adaptedto be broken. By disposing one of the circuit breakersG, (each being electrically connected with the battery 2) adjacent each of the respective four corners of the valise, it is apparent that the same will provide a sup port for the valise, the casters 7 being in direct engagement with the supporting structure. The weight of the valise is suificient to counteract the resistance of the several springs and cause casters 7 to come into contact with the valise bottom, and the con- 17 as illustrated to advantage in Fig. 2, The electric circuit being broken the alarm will remain quiet, but only so long as the valise remains unmoved. A raising or lifting of the valise until casters 7 disengage the support, will allow springs 15 to expand and 1 'move contacts 14 into engagement with contacts 16 and 17, such engagement closing the electric circuit and automatically sounding the alarm. A further advantage is obtained by the disposition of the circuit breakers 6 in the respective corners of the valise, as it is apparent that upon opening the valise,

- and moving the cover upon its'hingesgeither one or the other side of the valise is raised of the said valise causing one or more of i the casters 7 to be disengaged and the alarm sounded without bodily moving the said valis e from its support.

. From the foregom'g, taken in connection with the accompanying drawings it will be noted that the circuit wires are so arranged as to provlde for. the sounding of the alarm in the event of the disengagement of but one of the casters from its support; that the alarm may be rendered ineffective by operation of the lock indicated at 5; and that tact plates 14L to disengage contacts 16 and during such opening operation, the raising Witnesses;

that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realiz ing that the conditions concurrent with the adoption of my device will necessarily vary,

I desire to emphasize the fact that various minor chan es in details of construction, proportion and arrangement-of parts may be resorted to, when required, without sacrificing any of the, advantages of my invention, as defined in the appended claim.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

A circuit closing device for use in connection with movable objects comprising an open tubular casing secured to said object, a flange partially closing one end of said casing, a movable support for said object fitting said casing and projecting beyond the ends thereof, an enlargement formed on one end of said support for contact with said object to limit movement of said support,

a spring embracing said support and abut-' ting said enlargement and said partially closed end of the casing to move said enlargement out of engagement with said support upon movement of said object, diametrically opposed fixed contacts disposed eXteriorly of said casing, and a contact secured to said support and movable therewith into engagement with said fixed contacts through action of said spring to close the electrical circuit, substantially as described.

In testlmony whereof I affix my slgnature' in presence of two witnesses.
