Patented June 8, 1937 PATENT orries REFLECTOR ATTACHMENT FOR FLASHLIGHTS Charles Thoroughgood and Harold J. McLaughlin, New York, N. Y.

Application May 11, 1935, Serial No. 20,925 Renewed November 12, 1936 4 Claims.

This invention relates to illuminating and refleeting devices, and particularly, an improved reflector attachment for flash-lights.

One object of this invention is to provide a reflector-attachment that, when in its normal folded relation on a flash-light, forms a very compact arrangement that occupies but slightly more space than the flash-light minus the attachment, and can be carried in a pocket or in the hands of the user without detriment thereto or to any carrier therefor.

Another object is to provide a device of this kind that includes a very simple and thoroughly effective dual clamp that serves the purpose of securing the reflector-carrying arm on the casing of the flash-light, and frictionally maintaining the said. arm in any one of an infinite number of adjusted positions wherein it holds the reflector at an infinite number of different reflecting positions.

Another object is to provide such attachment with a second adjustable clamp to secure the reflector-unit frictionally on the adjustably mounted arm in such relation that the variety of adjustments is increased.

Another object is to provide the reflector-unit with a peripheral protecting flange that serves alike to protect the reflector or reflecting surface and the lens of the flash light.

The object or purpose of adjusting the reflector angularly with respect to the projected light-rays is to diffuse the light while directing it to any desired place nearby, for instance, onto a stairway about to be ascended or descended.

Other objects and important features are pointed out or implied in the following details of description, in connection with the accompanying drawing in which:

Fig. 1 is a side elevation of a flash-light having the improved reflector attachment secured thereon and adjusted angularly. Fig. 2 is a fragmental sectional view showing apart of the casing of the flash-light having the reflector attachment thereon in its normal folded or closed position, the part in section showing the reflector and. lens spaced from one another and surrounded by a protecting flange or rim.

Fig. 3 is a front end view of the reflector attachment detached, a part of the reflector-unit being broken away to clearly disclose the frictional joint of the clamp-band and the reflectorcarrying arm.

Referring to the drawing in detail, wherein the similar reference numerals refer to similar parts in the several views, the invention is described as follows:

The flash-light-casing is shown at 5, and includes asubstantiallycylindrical part 6 and a lens l; The reflector-attachment consists of a clamp-band 8, a clamp-screw 9, a clamp-nut Ill, an arcuate or substantially L-shaped link or arm ll having apertured ends, a clamp-screw l2, a clamp-nut l3, and a reflector-unit l4.

The reflector unit, in this embodiment of the invention, comprises a concave disc [5 having spaced apertured ears l6 united with its central outer part and being somewhat flexible so as to serve as clamping elements which are spaced just suiflciently to receive between them the link or arm II and to combine with the clamp-elements l2 and I3 for frictionally holding the disc l5 and its dependents in different adjusted positions in front of the lens I. Said dependents of the disc are the reflecting plate ll, the cement or securing medium l8 and the protecting flange or rim l9, the latter protruding beyond the face of the reflecting disc and normally resting against the margin of the adjacent end of the casing 5.

From the foregoing, and. in the drawing, it is seen that the parts 8, II and I l are pivotally united by means of the clamp-screws 9 and I2, and that by tightening or loosening the clampnuts I!) and I3, the frictional resistance is in creased or decreased so as to effectively maintain the parts in the desired adjustments, while permitting the changes of adjustment to be made easily and quickly.

It is not intended to limit the patent protection to the precise details shown and described in the foregoing, for the invention is susceptible of numerous changes within the scope of the inventive ideas, as implied and claimed, for instance, the reflector may be of metal instead of glass as indicated, and means other than that shown at l8 may be employed for securing the reflector in place.

What we claim as our invention is:

1. In an attachment for a flash-light, the coma proper relation to be moved to different angularly adjusted positions and frictionally maintained thereat, the substantially L-shaped arm providing a compact arrangement in relation to said clamp-band and reflector-unit while the latter is in its normal substantially parallel relation to said clamp-band.

2. In combination with a flash-light casing having a light-projecting end, a reflector-unit including a peripheral flange around the reflecting surface and normally resting on said light-projecting end of the casing, said reflector unit having a pivot-bearing on the side opposite to said reflecting surface, a pivot-bearing on said casing, and an arm having apertured ends pivotally connected to the'first said and second said pivotbearings and also frictionally engaged therewith so as to permit the reflecting surface to be moved to an infinite number of various angular adjustments with respect to said light-projecting end.

3. The combination with a flash-light casing having a light-projecting end, a clamp-band nor mally embracing said casing and having spaced apertured ends, a reflector-unit having its reflecting surface normally extending across said light-projecting end of the casing, said reflectorunit having spaced yielding pivot-bearings on the side opposite to said reflecting surface, an arm having apertured ends disposed respectively between the apertured ends of the clamp-band and between said yielding pivot bearings, clampscrews forming pivots that pass respectively through the apertured ends of the said arm and through the said apertured ends of the clampband and through the said yielding pivot bearings, and clamp-nuts operatively fitted on the respective clamp-screws for causing the clampband and the yielding pivot-bearings to frictionally clamp said arm with various pressures, substantially as shown, for the purpose specified.

4. The combination with a flash-light casing, of a reflector-unit having a reflecting surface on a side normally across the light-outlet of said casing, said reflector unit having a frictional pivot bearing on a side opposite to said reflecting surface, an arm pivotally connected to said pivot bearing and frictionally engaged with the latter'for maintaining it in difierent adjustments, and a dual clamp including a pivot engaged with said arm, said dual clamp also including means to clamp an element of said casing and means to frictionally clamp said arm so as to permit the latter to be adjusted and to hold it in different adjustments.
