ADJUSTABLE LAMP HOLDER AND REFLECTOR.
APPLICATION IILBD AUG. 26, 1911.
1,022,618, Patented Apr. 9, 1912.
GUSTAV I-I. AMEND,
OF DES MOINES,
IOWA.
ADJUSTABLE LAMP-HOLDER AND REFLECTOR.
To all whom it may concern Be it known that I, GUSTAV H. AMEND, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Adjustable Lamp-Holder and Reflector, of which the following is a specification.
The object of my invention is to provide a device of simple, durable and inexpensive construction that may be readily and quickly and easily adjusted to any of the reflecting mirrors usually employed 7 on computing scales, which device is adapted to hold and support an electric lamp and also direct the rays from said lamp upon those portions of the computing scales which the operator desires to use.
A further object is to provide a device of this class adapted to fit on mirrors of clifferent sizes and to be applied thereon without in any way altering or marring the mirror or its supporting frame.
My invention consists in certain details, in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows a side elevation of a com puting scale having my adjustment applied thereto as in practical use. Fig. 2 shows a detail perspective view of a device embodying my invention and applied to a mirror, the electric lamp being removed. Fig. 3 shows a longitudinal sectional view through a mirror, and through a device embodying my invention applied thereto. Fig. 4 shows a transverse, sectional view of the same. Fig. 5 shows a similar View illustrating the manner in which my device is applied to a mirror of a width greater than the width of the device, and Fig. 6 shows a rear elevation of a mirror frame having my device applied thereto.
Referring to the accompanying drawings,
I have used the reference numeral 10 to indicate a computing scale of ordinary con-- struction having thereon a bracket 11 to support a mirror frame.
The mirror frame is indicated by the nu meral 12 and has a mirror 13 mounted therein. Said mirror frame is connected to the bracket 11 in such a manner as may be Specification of Letters Patent.
Application filed August 26, 1911.
Patented Apr. 9, 1912.
Serial No. 646,117.
desired to reflect light upon any desired portion of the computing scale.
In many circumstances, it is difficult to obtain suflicient light upon the mirror to properly illuminate the computing scale and when artificial light is provided it frequently is in such position that its rays will not strike the surface of the mirror. To over come these objections, I have provided a supporting frame for an electric lamp, which supporting frame is made of two parts, one of which comprises an end piece 14. having lamp socket l5 fitted thereto. The end piece 14 is provided with integral sides 16 and said sides are preferably provided on both edges with inwardly inclined guide members 17. The other member comprises an end piece 18 with integral sides 19, the
latter being slidingly inserted between the guide members 17 In this manner a substantially rectangular frame is provided which is capable of adjustment longitudinally and is also capable of supporting the lamp 20 in the socket 15.
There is considerable variation in size of the mirrors ordinarily employed on com puting scales, and in order to provide an adjustment that may be fitted to mirrors of various sizes, I have provided a lamp supporting frame, capable of adjustment longitudinally, so that its length may be varied, and I have also provided means whereby this frame may be clamped to mirrors of greater width than the frame itself. In order to provide for attaching the device to mirrors of varying widths, I employ two flat bars 21 having slots 22 therein and I also employ a number of flat bars 23 each having a hook 24 at one end, and an extension 25 at the other end, which extension is provided with a screw threaded opening. A thumb screw 26 is extended through each of the slots 22 and is seated in one of the extensions 25. Assuming that the mirror is of approximately the same, width as the lamp supporting frame, as shown in Fig. 4, then the parts are connected as shown in said figure with the edges of the frame resting upon the face of the mirror adjacent to its side edges. If, however, the mirror is greater in width than the frame, then the sides of the frame are permitted to extend against the face of the mirror at points spaced apart from the edges thereof, as shown in Fig. 5 and the parts 23 are permitted to extend downwardly beyond the edges of the mirror where they are attached to the bars 21 by the screw 26.
In practical operation it is obvious that it is only necessary to provide a lamp supporting frame of proper size and shape to hold a lamp and to concentrate the rays of light from the lamp and the mirror upon the desired portions of the computing scales. The frame may readily be adjusted as to length to approximately fit the mirror but in regard to width no adjustment of this kind is necessary as the frame may rest upon the front face of the mirror. The hook arms 23 serve the double function of firmly holding the frame to the mirror and they also prevent longitudinal movement of the two frame members relative to each other. Furthermore they provide means for attaching the frame to a mirror Without in any way altering the mirror or marring the finish of the mirror frame and the attachment may be readily and easily connected or disconnected as desired. The size of the frame serves to concentrate the rays of light from the mirror and lamp and they also serve as a shade for the eyes of the operator.
I claim as my invention:
1. The combination of a mirror and supporting frame, a lamp holding frame and a lamp socket fixed thereto, said lamp supporting frame being shaped to rest against the surface of the mirror, and a clamp device passed around the back of the mirror frame and engaging the edges of the lamp supporting frame to hold the latter firmly in engagement With the mirror.
2. In a device of the class described, the combination of a mirror, a supporting frame therefor, a lamp supporting frame formed of two members, one member comprising an end piece and two side pieces, said side pieces being provided with guide members at both edges, a lamp socket fixed to said end piece, the other frame member comprising a central portion and two side portions, the latter being slidingly inserted between said guide members, two bars having slots in their ends, two hooked arms for each bar, each provided with a screw threaded opening and each being designed to engage one end of the bar and to overlap the adjacent portion of one of said frame members and screws passed through said slots and seated in said screw threaded openings, substantially as and for the purposes stated.
