To all whom it may concern Be it known that I, CLARENCE -W. W'rrrrn,

dent of North Bennington, in the county of Bennington and State of Vermont, have invented certain new and useful Improvements in Reflectors, of which the following is a specification.

This invention relates to reflectors, more particularly to reflectors for use with incandescent lamps, and the objects of the invention are to construct a reflector that is very strong and durable.

Further objects of the invention are to provide a guard for the open end of therefiector that can be locked into position to prevent breaking or stealing of the lamp.

To. the accomplishment of the above objects and to such others as may hereinafter appear the invention comprises a reflector, having at its open end an outwardly extending shoulder at right angles to a downwardly extending flange having a beaded edge, and means for holding the outer edge of a guard in position against said shoulder.

The invention also comprises means for removably locking the guard in the-open end of the reflector.

Referring to the drawings: Figure 1 is a side elevation of a reflector made in accordance with the invention secured to an ordinary incandescent lamp socket. Fig. 2 is a bottom view of Fig.1. Fig. 3 is a View showing the reflector section. Figs. l and 5 are detail views of the locking means for the guard.

In the drawing A designates an ordinary electric light socket having a circular rib B which is adapted to engage a corresponding groove or recess C provided in a split ring D which is made of metal and adapted to be sprung into position on the socket A as clearly shown in Figs. 1 and 3. The lower portion of the split ring D is threaded and adapjted to engage a similarly threaded collar secured to the top of the reflector F.

When the lamp Gr is screwed into position it will be seen that the. reflector cannot be removed from the socket without first removing the lamp, as the glass globe of the lamp is larger than the opening in the top of the reflector.

The reflector .F is preferably made of aluminum, although if desired the same can be made of any other suitable metal, that v P which is can be spun into shape and formed at its open end with an outwardly extending shoulder H at right angles to a downwardly extending flange J, having a beaded or rolled edge K. This shaping of the open end of the reflector by providing a shoulder having a beaded flange greatly strengthens the reflector, which is very desirable as reflectors of this type are put to very rough usage, and it is important that the reflector retain its original shape to properly reflect the light.

The present method of shaping the open end of the reflector permits of a suitable guard or covering M being secured in the offset portion of the end of the reflector so as not to interfere with the proper reflecting qualities of the reflector. In the drawing the guard or covering M is shown as a wire screen of very large mesh, the edges of which are secured to a large wire ring N which fits in the oflset portion of the reflector as clearly shown in the drawings. This guard or covering M prevents breaking of the lamp G and when the guard M is locked in position in the end of thereflector also prevents the lamp being stolen, as the lamp cannot be removed without first removing the guard. In the present instance the guard is secured in position by means of two projections or pins 0 secured to the flange J and also by means of a movable pin P secured to a flat spring Q, as clearly shown in Fig. 4. In the present instance the locking of the guard Min the endof the reflector is accomplished by'locking the pin provided with a slot It in which the bolt S of the lock T is adapted to en gage as clearly shown in Figs. 1! and 5. In-

stead of providing a wire guard such as described for closing the end of the reflector, a piece of glass which may be colored, when the same is to be used for photographic purposes, can be used and held or locked in 1 position in the same manner. The 'oif-s'et portion of the end of the reflector makes" a light tight joint and when a red piece of glass is used for photographic purposes no white light will pass around the edge of the glass which is a very important feature of this construction.

While the invention has been described with particular reference to the details of construction, the same'is not to he ccn'sid ered as limited thereto, as many changes g amass? can he made and still fall within the scope of the invention setjfiorth in the following claims.

What I claim is? v 1. A reflector comprising'in combination a guard, the open end of the reflector haying ail-outwardly er ztending shoulder at right angles to a downwardly extending flange, and means for remo'yahly holding the outer edge of said guardian position against said shoulder, said shoulder and said flange being arranged out ,ef the path of the light reflected by said reflector.

v 2. A reflector comprising in combination a guard, the open end of the reflector havii'ig an outwardly extending shoulder at right ones-Enos W. WHITE.
