LTUMQWW v va is. at it who CHARLES E. GODLEY,'OF DETROIT, MICHIGAN, ASSIGNQR T 3 EDMUN'DS .dli) S ilts AS CORPORATIGN, 0F DETROIT,
MICHIGAN, A CORPORATION OF REV- LAMP-MOUNTING.
To all whom it may concern Be it known that .1, CHARLES E. GonLnY, -a citizen. of the United States, and residing at Detroit, in the county of Wayne and State of lllichigan, have invented a new and 1111- proved Lamp-Mounting, of which the following is a specification.
This invention relates to means for so supporting projecting lamps such as headlights, searchlights and spot-lights, as to permit them to be swung in any desired manner and the rays of light therefrom to be projected in substantially every direction, and its object is to provide a lamp mounting for this purpose which will be simple, strong and durable, and which can be manufactured at comparatively low cost.
This invention consists in combination with a lamp, of a st itionary support having a bearing in which a curved member is revolubly mounted, this member l'iaving a hearing at its outer end, a lamp mounted in the hearing at the outer end, the bearing consisting of a cylindrical member extending into a split sleeve and a collar to cause the sleeve to grip the cylindrical member.
In the accompanying drawings, Figure l is an elevation of a searchlight mounted on an upright rod by means of this improved mounting. Fig. 2 is a vertical section of this mounting. Fig. 3 is a plan thereof. Figs. 4 and 5 are sections on the lines 4% and 5-5 of Fig. 2. Fig. 6 is a side elevation ,of a Searchlight mounted on a base. Fig. 7 is a vertical section thereof through the bearing for the lamp. Fig. 8 is a section on the line .88 of Fig. 7.
Similar reference characters refer to like .parts throughout the several views.
The lamp body 1 shown in Figs. 1 to 5, inclusive, is provided with a hollow trunnion or hub 2 having a circumferential groove 8. The supporting clamp t is shown provided with a stiffening rib 5 and parallel ribs 6 by which an upright rod or bar 7 may be engaged. A bent rod 8 is slidable in a proper hole in the clamp member 4. A. nut on the rod forces the end 9 against the upright 7, which end has-a groove 10 which receives this rod or bar. It will be understood, however, that l an not confined to this form of clamping defii ie, as any other desired construction of support may be e1nployed. A hollow hub or trunnion 12 hav- Speeification of Letters Patent.

,ed in the hub T s-iterated do 33;, :lhttl. Serial in. 14min,
ing a groove ing member.
The member (:(Hillifilllfi these trunnions is in the form oil a hollow elbow 1.5 having its arms or branches ending; in. sleeves fitting over the hubs) and 19. and having tapering rings or seats 16 and threaded ends 17. The sleeves that embrace these hubs are formed with slits 18 as shown in Figs. 4a and so that they may be caused by the collars l9 and 20 to lirinl' grip the hubs. 'lhese collars have tapering seats that lit the rings 16 and are also formed with thread ed portions 23 that engage the threaded ends 17 of the split sleeves of the elbow. 'lhese collars are forced up onto the sleeve-ends of the branches of the elbow by means of the screw threads to a greater or less extent and the grip of the split sleeves on the hubs is greater or less in proportion thereto. llhe lamp 1 can therefore be swung around the vertical axis of the hub 12 and around the horizontal axis of the hub 2 and will be held in any desired position by the friction between the hubs and the elbow.
The screws S37 extend into the grooves 2i and 123 and prevent the hubs from slipping out of the sleeves. The support 7 will pre vent the lamp from being swung entirely around on the hub 12 in either direction and thus will prevent the wires 26 from being twisted too far. In order to prevent the lamp from being swung entirely around on the axis of the hub 2 a small key 29 mount- 2 across the groove 8 therein, against which key the screw 27 in that end of the e bow will contact when the lamp swung in either direction. This again Will prevent the wires 26 from being twisted 'lhe collars may have openings 2-8 through which the screws are inserted and adjusted.
It is apparent that the revoluble member may be forked and carry a hearing at the end of each branch. In Figs. 6, I and 8, the base or support 31 provided with a split sleeve 32 provii'led with a screw that enters the groove 3-1 in the cylindrical extension 35 of the fork S6. The base 31 and one of tl'le ztll'ns of the fork 36 as well as its hub are hollow to permit the cable 37 to pass to the lamp. A collar 40 on the split sleeve 32 is adapted to cause it to grip the hub 35 as before described.
