SPECIFICATION forming part of Letters Patent No. 557,888, dated April *7, 1896.

Application filed June 20, 1895. Serial No. 553,459. (No mod l.)

To all whom it may concern:

Be it known that I, XVILLIS EUGENE Ron- INSON, of Faribault, in the county of Rice and State of Minnesota, have invented a new and useful Improvement in Shades for Electric Lights, ofwhich the following is a full, clear, and exact description.

My invention relates to a shade for electric and other lights, especially incandescent lights and it has for its obj ect to so construct the shade that it may be adjusted vertically and laterally, or at any angle to the light, thus providing a shield for the eyes, which may be adjusted to suit the position of the person seated near the light, or adjusted to control the intensity of the light at a distance therefrom.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of an incandescent light having the improved shield applied, the shield being in edge view. Fig. 2 is a transverse section through the globe of the electric light, and Fig 8 is a side elevation of the shield.

In carrying out the invention the device may be said to comprise a clamp A, a holder 13, and a shield O. The clamp A is constructed preferably of spring-wire or equivalent material bent upon itself to form an open loop 10 at one end and a closed loop 11 at the opposite end, the two loops being obtained by coiling the wire upon itself after it has first been bent to a substantially U shape. The open loop 10 is given a rounded form and its terminals are made to flare outward in opposite directions, while the closed loop 11 is more or less rectangular in general contour.

The holder B preferablyconsists of a plate T-shaped in general contour, comprising parallel shanks 13, each of which forms a portion of a head 14. The upper and lower members of the head, since it is double, are spaced a predetermined distance apart, and the upper member is given somewhat of an arched form and is provided with a longitudinal concavity at or near its center, being located over the space between the shanks 13, and the formation of the holder is completed by placing between the members of the head a springleaf 16. The closed loop is passed through the head between the spring-leaf and the recess 15, as shown in Fig. 1. Therefore when the holder is turned at any desired angle to the clamp, or in the same plane therewith, the spring-leaf will serve to retain the holder in position at any point to which it may be carried, since the space between the outer member of the head and the spring-leaf is just sufiicient to receive the loop 11, and the spring has constant bearing thereon.

The shield C may be of any desired shape, being given somewhat of a pear shape in the drawings, and it may be made of any approved material. The shield is passed between the shanks 13 of the holder and secured thereto in any suitable manner. The open loop 10 may be placed around the neck of the globe D of the light, as illustrated in Figs. 1 and 2, or around the socket near the key, and the said open loop is made of such size that its members will be sprung apart when the attachment to the lamp is made. Thus it will be observed that the shield may be adjusted vertically on the globe by carrying the clamp upward or downward, and that it may be carried to any side of the globe by turning the clamp around the same, and that the shield may be placed at any angle to the globe by carrying the holder to an upper or a lower position. It is also evident that the shade maybe used in connection with an ordinary house-lamp, if desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A shield, the same consisting of a clamp having an open loop at one end, a holder pivoted upon the clamp at the opposite end, a spring carried by the holder and in constant engagement with the said clamp serving to maintain the holder in whatever position it may be adjusted relative to the clamp and a shading-leaf carried by the said holder, as and for the purpose specified.

2. A shield for electric or other'lights, the same comprising a shading-leaf, a holder attached to the said leaf, provided with a head containing a spring, and a clamp having a loop passed through the head and in constant contact With the spring therein, as and for the purpose specified.

3. A shield for electric or other lights, the same comprising a shading-leaf, a holder attached to the said leaf and provided with a head containing a chamber, the outer wall whereof is ridged at the center, and a spring located in the said chamber below the ridge,

with the said spring, as and for the purpose 20 set forth.

WILLIS EUGENE ROBINSON.
