-GEORGE J. LYNCH, OF NEW YORK, N. Y.

' ALARM DEVICE.

To all whom it may concern:

Be it known that I, Gnome J. LYNCH, a citizen of the United States, and a resident of New York, county and State of New York, have invented a. certain new, and useful Improvement in Alarm Devices, of which the following is a full, clear, and exact specification.

This invention relates more particularly to a type of alarms adapted to be used in the signaling device disclosed in my pending application for a patent, serially numbered 193,315, filed September 26, 1917, and

has for its ob ect primarily to provide ade vice wherein a lamp and a bell are combined for utilization on an automobile and other vehicle so that by closing a normally open electric circuit the lamp will be lighted and the bell rung synchronously for sounding an alarm of impending danger in emergency. The invention consists essentially of a casing with an exposure opening which may be opened and closed by a glass door, and in the casing is a partition dividing the interior of the casing into two chambers. The partition is provided with a support for removably holding an electric lamp, while on the casing is a bell, and both the lamp and the bell are interposed in a normally open electric circuit for being closed to light .the lamp and ring the bell synchronously so that the warning of impending dangenmay be heard as well as observed.

' Another object of the invention is to pro vide in the casing electrically operative means to cause a simultaneous ringing of the bell and lighting of the lamp; and to provide an alarm device of a simple and effi'cient construction which may be made in various shapes and sizes.

A practical embodiment of the invention is represented in the accompanying drawing forming a part of this specification in which similar characters of reference indi cate corresponding parts in all the views, the said invention being more fully described hereinafter, and will. then be pointed out in the claims at the end of the description. In the drawing, Figure 1 is a front elevation, partly broken away and partly in section, of one form of alarm device embodying my invention, and

Fig. 2 is a detail vertical longitudinal section taken through the alarm device.

Application filed November 13, 1917. Serial No. 201,832.

The lamp 10 has a casing 12 which is'preferably of substantially a cone-shape, and hinged or otherwise attached to the casing is a. glass door-13 of a red, green, white or other color for allowing the open end or entrance. to the casing to be opened and closed. Arranged transversely of the interior of the casing 12 at the door 13 is a removable or fixed partition 1 1 of preferably a parabolic shape disposed so that its concavity is in opposed relation to the glass door. This partition is of a curvature whereby its central part is positioned approximately midway of the interior of the casing, and the surface of the partition 0pposed to the door may be silvered, or polished, or covered with mirrored glass to provide a reflector 15 for reflecting rays of light through the glass door. By providing the partition in this fashion the interior of the casing 12 is divided into a front chamber 16 and, a rear chamber 17, and through the center of the partition as well as through that one of its ends protrudes into the front chamber 16 of the casing besides protruding exteriorly of the casing. The end portion of this tubular socket member disposed through the opening 18 of the casing is exteriorly threaded, and on this threaded part interiorly of the casing may be a nut 22, while on the threaded part exteriorly of the casing may be a second threaded nut 23. By screwing these nuts accordingly they will be moved into engagement with the wall of the casing, and in turn the socket member will be held against accidental movement in the casing. In the end of the socket member 21 which protrudes into the front chamber 16 of the casing is mounted an electric lamp -24 of any well known or preferred type for being lighted so that its rays of light will be reflected by the reflector 15 through the glass door 13 of the casing for being observed by a person to signal impendin danger.

The nell 11 is preferably formed of a sound producing metallic shell, or hood 25 of somewhat the shape of an inverted cone, and the apex of this cone-shaped shell is mounted, at 26, on the upper end of a tubular post 27. The lower end of the tubular post 27 is exterior-1y threaded, and this threaded end of the post is screwed into the threaded opening of the casing 12 of the lamp. On the threaded end of the post in the rear chamber of the casing is screwed a nut 28, while on the threaded part of the post exteriorly of the casing of the lamp is another nut 29, and by screwing these nuts acccordingly they will be moved into clamping engagement with thecasing of the lamp so that the post with the shell 25 will be tlghtly held to the lamp. Through the tubular post 27 in proximity to the open end of the metallic shell 25 of the bell is an opening 30 through which is movably disposed a hammer 31 for ringing the bell. This hammer is preferably in the form of a rod disposed right angularly with respect to the post, and on the free end of the rod is a metallic ball in closely spaced relation to the metallic shell so that when the rod is vibrated crosswise in the shell the ball will contact intermittently with the shell for ringing the bell. The hammer 31 is provided on the upper end of an-armature 34 which is in the form of a metallic bar movably disposed in the tubular post, and this armature or bar is of a length to extend through the open end of the post for some distance into the rear chamber 17 of the lamp casing 12.

Part of the armature is in spaced proximity to the cores of two magnets 35 and 36 provided interiorly of the chamber 17 of the casing of the lamp. The magnets 35 and 36 may be of any well known or preferred types adapted to be energized for vibrating the armature 34 through the medium of a normally open electric circuit, as 37, which when closed will cause the lamp 24 to be lighted synchronously with the ringing of the bell, as will be hereinafter more fully explained. The lower end of the armature 34 is pivoted, at 38, to a bracket 39 which also supports the magnets 35 and 36, and this bracket is held stationary in the rear chamber of the casing by being bolted or otherwise secured, as at 40 and 41, to the wall of the casing of the lamp. The mag nets 35 and 36 are coupled together by a wire, as at 43, and extending from the pivoted end 38 of the armature 34 is a spring finger 44 arranged so that its free end is adapted to contact with the bracket 39 for serving to cause the armature to be swung from the cores of the magnets. Also to the pivoted end of the armature 34 is secured one end of another spring finger 45 which is disposed upwardly in spaced parallel relation to the face of the armature which is opposite to the magnets. The free end of the spring finger 45 is in movable contact with a set screw 46 rotatably held in part of the bracket 39 so that by adjusting this screw accordingly the armature will be properly positioned for being actuated when the magnets 35 and 36 are energized by closing the electric circuit 37.

The circuit 37 may be similarly provided as well as being opened and closed in a like manner to the electric circuit disclosed in my pending application for a patent for signaling device for vehicles, Sr. No. 193,315, filed September 26, 1917, and which includes two wires 47 and 48 leading from a battery, not shown, or other suitable source of electricity supply to the poles of the lamp 24 through the tubular socket 21. To part of the wire 47 interiorly of the socket of the lamp is connected a wire 49 which passes through an opening 50 in the socket to armature 34, and from the set screw 46 is a wire 51 leading to the magnet 36. From part of the wire 48 interiorly of the tubular socket 21 is a wire 52 which leads to the magnet 35 so that when the circuit is closed the current will pass over the wires 47 and 48 to light the lamp 24. With the closing of the circuit, the current will pass over wire 52 to the magnet 35, over wire 43 to the magnet 36 and over wire 51 to the set screw 46. From the second terminal of the battery the current will pass over wire 49 to the armature 34 so that, with the energizing of the magnets, said armature will be attracted to the poles of the magnets, and the spring 44 will then cause the armature to be released to cause the spring 45 to be recontacted with the set screw 46, so that the bell will be rung with each closing of the circuit.

In the foregoing description, I have embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle, or sacrificing any of the advantages of this invention; therefore I reserve to myself the right to make such changes as fairly fall within the scope thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a lamp having a casing divided into a front light chamber and a rear chamber by means of a concave reflector, of a sound producing shell mountei upon the exterior of the lamp casing and spaced therefrom by means of a tubular post, actuating means mounted in said rear chamber of the lamp casing and including an actuated member extending through said tubular post with its free end at a point adjacent said shell outside of the lamp casing, and a hammer on thefree end of said actuated member.

2. The combination with a lamp having a casing divided into a front light chamber and a rear chamber by means of a concave reflector, of a sound producing shell mounted upon the exterior of the lamp casing and spaced therefrom by means of a tubular post,

'electro-magnetic actuating means mounted in said rear chamber of the lamp casing and including an armature extended throughsaid tubular post with its free end at a point 15 adjacent said shell outside the lamp casing,

and a hammer on the free end of said arma- E. W. JONES, F. J. LYNCH.
