INITED STATES PATENT rr ce@ THOMAS VALSH, OF MONTREAL, CANADA.

FlRE-ALARM BOX.

SPECIFICATION forming part of Letters Patent No. 545,141, dated August 27, 1895.

Application tiled April l2, 1895. Serial No. 545,483. (No model.)

:1"0 @ZZ whom ir? may concerns Be it known that I, THOMAS WALSH, of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements i n Fire-Alarm Boxes; and I do hereby declare that the following is a full, clear, and exact description ol' the same.

This invention has for its object to provide, in connection with tire-alarm boxes or signaling apparatus, means which shall have a deterrent oiect upon mischievous persons sending false alarms; and to such end the invention consists of an attachment in the form of an automatically-operated grip or handcuff acting to detain the person operating the alarm until the arrival of the remen.

Havingthus referred to the object and principle of my invention, I will now describe what I consider to be the most practical embodiment thereof in a lire-alarm box having the usual front hinged door requiring to be opened before the alarm can be rung, reference being had tothe annexed drawings forming a part of this specification, in which like symbols indicate corresponding parts, and whereinl Figure l is a front elevation of an alarmbox with the front of the easing or covering for my improved attachment removed; Fig. 2, asimilar view, but with the front of the casing or covering partially broken away and showing the operating parts in differentworking positions; Fig. 3, a transverse vertical section on line 3 3, Fig. l.

The alarm-box is in this case shown as of the usual type, havinga hinged door a, and it is on this door that I place my attachment, although in other constructions of box it is equally applicable, since the main requirement is a connection with the locking mechanism ofthe alarm-box, Whether it be carried by the door or any other part thereof. The door then in this case is preferably locked by means of a vertically-sliding bolt b, the upper end of which engages a projecting hook.

or latch c, carried by the frame of the boX. The bolt is notched at b on one side, and a trigger or detent d, adapted to engage such notch, is mounted on the spindle cl of an operating-handle d2, also carried by the door.

Pivotally suspended from a bracket e, extending some distance out from the face of the door, are a pair of rodsff, each having semicircular bends ff, and outwardly-in- 55 b2, from the lowerend of the bolt l), carrying a bar or yoke-piece b3, (preferably pivoted to the projection b2, so as to avoid any chance of the bolt Z) being jammed by lateral movement 65 ofthehandcu) having slots b4 to receive the inclined portions f2 of the grip-rods, which, upon the yoke-piece being moved vertically up or down with the bolt, are necessarily opened or closed by such movement. be seen, therefore, that if a hand is passed through the handeuff to reach the operatinghandle d2, the moment it is rotated and the bolt freed so as to drop the rods fwill be drawn together and so detain the person until 75 such bolt is lifted.

To insure the passing of the hand through the handculf an inclosing-casing g is used, which prevents the handle d2 being reached except through an opening g' in such casing, 8o

which is directly in line with the handle and handcu. Of course the lifting of the bolt could be performed by some special means, solely under control of the lire department;

but I prefer to .use an automatic release pref- 8 5 erably of the following nature and construction: A lever h is pivoted to the lower end of a laterally-swinging bar h', and has one end pivotally connected Wit-h the bolt and its opposite end attached to a sliding carrier h2, 9o

moving inl a suitable slotted guide L: on the face of the door d.

The casing g is formed with a vertical compartment g2, in which the carrier Works, and

such carrier supports an open-topped recepo 5 tacle m in the compartment, which receptacle is adapted to be gradually filled with sand or any other granular material normallycarried in a hopper n, formed in the upper part of the casing above the compartment g2, and the too flow of which sand therefrom is controlled by means of a finger p, extending from the swing- This operation of the 6o It Will 7o ing bar 71', which, when the bolt l) is raised into its locking position,is located across the open delivery-mouth of the hopper, and when the bolt is dropped is moved laterally away, so as to uncover the discharge and allow the Sand to flow into the receptacle m until its weight overcomes the pressure of a retaining-spring sin the side of the casing when it will operate the lever 7L and so raise the bolt. The flow of the sand can be timed so that the person will not be released until the firemen have arrived and the period of detention can be varied by the use of interchangeable slides q, having discharge-apertures r of various sizes located at the mouth of the hopper. Of course other forms of automatic time-release mechanism, either' electric clockwork or the like, might be used.

As an auxiliary device, to be used when there is no necessity for operating the handcuff through the bolt b, I arrange a second bolt 'it alongside the one h and provide a nger u on the spindle of the handle to engage a projection u2 on the bolt u, by which such bolt can be raised independently to elevate the hook or latch c, serving to hold the door closed.

W'hat I claim is as follows:
