WALTER E. CHRISTIAN, or" KENOSBA, Wisconsin, Assmnon. To THE BADGER BRASS mmuraoruame oomrAn'Y, or KENOSHA, WISCONSEN, A CORPORATION OF WIS- oonsn v i LAMP.

PatentedMar. 4, 1913.

Application filed June 17, 1912-. Serial No. 704,046.

though in its broader aspects the invention is'not necessarily so limited;

The salient object of theinvention is to provide, in a construction of the above character, simple and improved means for detachably lockin the reflector body to the door frame an at the same time rigidly confining the front glass or crystal in position. f V

Subsidiary objects are to provide a construction in which the reflector may be readily locked to the door structure or detached therefrom, and without the .aid

of screws, bolts or other extraneous fastening devices; to provide a construction in which the reflector is provided with a plurality of pivoted fingers or latch members adapted to have spring-lockingengagem'ent with slotted striker members carried by the door body; to provide a construction in which these locking devices are effectively concealed within the lamp and yet ready access may be had thereto by merely opening the door and in general to provide an economical and yet effective structure of the character referred to.-

The invention consists in the matters hereinafter described, and more particularly pointed out in the appended claims.

In the drawings'Figure 1. is a horizontal sectional view of an electric lamp equipped with my invention; Fig.2 is a vertical sec tional view taken on lines 22 of Fig. 1 and looking in the direction of the arrows; Fig. 3 is a fragmentary detail view showing one of the pivoted latch members; and Fig. 4 is a similar view showing one of the coiipe'rating slotted striker members.

Referring to the drawing,1 designates the lamp body, to which is hinged, as shown at 2, the door frame 3, which in he present instance comprises a ring 4 provided at its door is locked in closed position by means of a screw" 6 and nut 7, the former being rigidly fixed in the boss 8 secured to the outer edge of the ring 4. When thedoor is closed, the 'screw lies within a forked bracket 9 rivetedto the outer side of the lamp body, as shown at 10. The door may be locked or opened by merely turning the nut 7. The lamp is supported by means of the usual bracket 11 and confining. screw 12, the bracket fitting over a post (not shown) carried by the car body.

Within the lamp body is seated the con.- cave reflector 13, the rear end of which is apertured to receive a socket member 14,

outer edge with an inturned flange 5. The i within which is sup orted suitable electrical connections 15 for t e bulb 162 These parts, however, form no part of thepresent invention, and need not be described in detail.

As is seen more clearly in Fig. 1, the outer edge of the curved reflector 13 is provided with an annular rim or flange 17 The front glass or crystal 18 is secured between this flange 17 and the member 5 of the door frame by the novel mechanism now to be described. To the flange or rim 17 are secured a plurality of circumferentially disposed supportin blocks 19, to each of which iis pivoted, as s own at 20, a spring latch member 21.. The outer side of each of these latch members 21 is provided with a locking lug 22, and at its free end each latch member is turned up to form an ear23 by which the latch member can be more readily forced into or out of locking position. As shown more clearly in Fig. 3, the main'body of the latch-member is inclined away from the supporting blocks 19, the arrangement being such that the latch members normally spring rearwardly or away from the blocks 19. Each of the latch members 21 is adapted to have lockingengagement with a corresponding striker member 24 which is secured to the inner side of the ring 4 of the door structure. Each of these striker members '24: is provided at its inner face with a-recess or slot 25 for receiving the lugs 22 of the latch members.

In looking the reflector to the door structure, the'glass or crystal is first inserted in place and the reflector turned until the lugs 22 of the latch member are opposite the cor-. responding slots 25 of the strikers. By

pressing on the inclined ears 23 the latch the slots members will be forced downwardly and at the same time swing on their pivots sufficiently for the lugs 22 to enter the slots 25. When pressure is released the lugs automatically snap into effective locking engagement with the striker members. It is to be noted that-the ears 23 are so arranged relative to the pivoted latch members that by pressing down on the ears the latch members are not only forced down\\-'ardly, but inwardly sufficient for the lugs 22 to engage The latch members may be released by simply forcing the ears downwardly and outwardly until the lugs pass out of the slots.

The invention is not limited to the details of the invention shown except as set forth in the appended claims.

I claim my invention:

1. In a lamp, the combination with a body portion, of a door structure secured thereto, a reflector within the lamp body and adapted to move with the door structure, and means for detachably locking the reflector to the door structure, com arising pivoted latch members secured tot e reflector and cooperating striker members carried by the door structure.

2. In a lamp, portion, of a door structure pivoted thereto, a reflector within said lamp body and moving with the door structure, and means for detachably securing the reflector to the door structure, comprising a plurality of resilient latch-members secured to the reflector, and cooperating striker members secured to the door structure and having cooperative spring-locking engagement with said latch members.

3. In a lamp, the combination with a body portion, of a door member movably connected thereto, a reflector member within said body portion and adapted to move with the door member, and means for detachably locking said members together, comprising a plurality of spring latches carriedby one member, and a plurality of striker members carried by the other member and havin spring-locking engagement with sai latches.

4. The con'ibination with a main body portion, of a member pivotally connected to said body portion, a second member within said lody portion, and'means for detachably locking said members together, comprising pivoted spring latches carried by one of said members, and cooperating strikers carthe combination with a body ried by the other of said members and adapted to have spring-locking engagement with said latches.

5.111 a lamp, the combination with a, main body portion open at its outer end, of a door frame hinged to said body portion and comprising a ring provided at its outer edge with an inturned flange, a reflector within said body portion and provided at 'its outer edge with an outturned flange, a

glass seated between said flanges, and means for locking the reflector to the door frame, comprising a plurality of spring latch members pivotally connected to sair outturned flange and provided with locking-lugs, and a plurality of striker members secured to the inner side of said ring and slotted or recessed to receive the locking lugs of saidv latch members.

(3. In a lamp, the combination with a main body port-ion open at its outer end, of a door frame hinged to said body portion and comprising a ring provided at its outer edge with an inturned flange, a reflector within said body portion and provided at its outer edge with an outturned flange, a glass seated between said flanges, and means for locking the reflector to the door frame, comprising a plurality of slotted striker members secured to the side of said ring, and a plurality of latch members pivoted to the inner edge of said flange and each comprising a spring body portion, an outturned lug adapted to have locking engagement with the slot of the corresponding striker member, and an inclined ear portion secured to the outer edge of the latch member.

7. In a lamp,- the combination with a main body portion, of a door member piv oted thereto, a reflector member within said body portion, a striker carried by one of said members, a spring latch pivoted to the other of said members and adapted to have locking engageu'ient with said striker.

8. In a lamp, the combination with a main body portion, of a door member pivoted thereto, a reflector member within said body portion, a striker carried by one of said members, a spring latch pivoted to the other of said members and adapted to have locking engagement with said striker, said latch having an inclined extension at its free end.
