UNITED STATES PATENT OFFICE.
GEORGE E. BREHMER, OF SYRACUSE, NEW YORK.
SPECIFICATION forming part of Letters Patent No. 373,219, dated November 15, 1887.
To all whom iii may concern:
Be it known that I, GEORGE E. BREHMER,
cuse, in the county of Onondagavand State of New York.'have invented certain new'and useful Improvements in Lamp-Shades, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to lamp-shades; and my object isto provide a shade applicable to different forms and sizes of lamps, that is readily adjustable for the purpose ofpreventing the rays of light from fallingvin undesired directions, and this by a simple, cheaply manufactured means.
With these objects in View the invention consists in certain features of construction, hereinafter described,and particularly pointed out in the claims.
Referring to the drawings, Figure l isaside elevation of an ordinary lamp,shown in dotted lines, and provided with myimproved shade. Fig. 2'is a perspective of the shade detached; and Fig. 3 is a modification, hereinafter described.
Like lettersindicatelike parts in all the iigures.
A represents a lamp provided with the ordinary form of burner, having a cylindrical body, A', upon which, as usual, the shade is mounted.
B represents a resilient circular clampingin this instance of sheet metal, but which, if desired, may be formed otherwise, as will hereinafter appear.
Soldered orv otherwise secured to the collar Bis a wire shade-support, C, .which is bent downwardly and upwardly, as at C O2, to form the' depending portion C3, for the pur# pose of permitting thev shade to be lowered a proper distance. The arm C"l is projected to a point above the collar B and again bent upon itself in an opposite direction to form the locking-arm G4, the arms O'l O" forming a standard or support for the shade.
D represents the shade, preferably of concavovconvex form, made of sheet metal, but which may be made in any suitable form, ornamented ornot, and of a desirable material.
and otherwise iinished,to serve the function l of a reilector, so that while reflecting the rays of light in one direction the shadow is cast in the opposite direction.
Projecting outwardly from the inner or concave surface of the shade D, and suitably secured thereto, is a bail, D', which embraces or is connected to a sleeve, D2, adapted to embrace and slide upon the supporting-standard formed .by the two arms C2 G4. As the latter arm is resilieut,it is evident that by compressing or forcing it toward the arm G2, as shown by dotted lines, Fig. 2, the contact of the arm O4 with the inside of the sleeve D2 is broken, whereby the shade may be either allowed to fall by gravity or adj usted up or down bythe hand to a desired point,whe`n, by releasing the arm C, it (the arm) will assume its normal or distended posit-ion and bind the sleeve and rev Hector in the desired position.
In Fig. 3 I have illustrated a modification, and it consists merely in forming the shadesupporting standard and collar B of a single piece of wire. In this instance the wire,after being bent to form the arms C? C4 C ,is carried in a circle horizontally and bent in zigzag form vertically to give the proper bearing to.
the same. This form may be found more desirable on account of its cheapness.
`Having described my inventiomwhat I claim l. In a shade attachment for lamps, the combination of a collar adapted to embrace the burner thereof, and having a wire standard projected therefrom bent to form a depending sleeve-receiving portion,and aspring locking-arm, in combination with a shade having abail provided with a sleeve mounted on the standard and adapted to be locked by said arm, substantially as specified.
2. The combination of the spring-collar B, the wire @connected thereto, and bent, as at C C, to form the depending sleeve-receiving portion C3, and having the spring locking-arm C4, with the shade D, provided with the bail D', and sleeve D2, substantially as specified;
' In testimony whereof I affix my signature in presence of two witnesses.
GEORGE E. BREHMER.
