JOHN HUBBELL, on NEW YORK, N. Y.

IMPROVEMENT IN SCREEN-HOLDERS FOR LAMPS.

Specification forming part of Letters Patent No. 189,224, dated April 3, 1877; application filed February 22, 1877.

To all whom it may concern:

Be itknown that I,.JoHN E. HUBBELL, of the city, county, and State of New York, have invented a new and Improved Screen-Holder for Lamps, which invention is fully set forth in the following specification, reference being had to the accompanying drawing, in which the figure in the accompanying drawings illustrates a students lamp having my improved screen-holder applied thereto according to my invention.

Similarletters indicate corresponding parts.

My invention relates to a screen-holder which is designed to be .attached to a lamp, either permanently or temporarily, so that it is always available or ready for use, and not liable to become misplaced. It consists in a bracket, which is so constructed that it can be firmly attached to a lamp and detached therefrom at pleasure, and which carries a horizontal arm of such form that a screen can be secured thereto in such a manner that the screen is held in a vertical position in front of the lamp to which the holder may be attached, the construction of the bracket and its attachment to the lamp-standard being fully hereinafter described.

In the drawing, the letter A designates the bracket, and B is the horizontal arm, com posing my improved holder. The bracket A is made of two arms, a a which are riveted or otherwise fastened together, and connected by a brace, a One of the arms a a is provided with an eye, I), at its inner end, while the other arm is bent to form a hook, c, at said inner end. This construction of the bracket A renders it applicable to a student lamp, andwhen it is applied to this class of lamps the head of the standard 0 of the lamp is unscrewed, and

The bracket A is thus firmly attached to the lamp, while it can be detached therefrom at will.

The horizontal arm B is riveted to the arm a of the bracket A, or secured thereto in any other suitable manner, and in said horizontal arm B are formed a series of holes or perforations, d, to permit of connecting thereto a screen, D. The holes or perforations d extend throughout the entire length of the horizontal arm 13, and the screen D is secured to the arm by means of rivets passed through the perforations d; but it is obvious that the screen D can be affixed to the horizontal arm B in various other ways than the onejust described, and I do not wish to limit myself to any precise means for effecting this object.

What I claim as new, and desire to secure by Letters Patent, is-

A screen-holder for lamps, composed of the bracket, constructed of the arm a inclined arm a and horizontal arm B, having the screen D attached thereto, the arms a and'a. having the eye I) and hook c, for securing the bracket to a lampstandard, the whole being combined substantially as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 20th day of February, 1877.
