ADJUSTABLE PROTECTING DEVICE FOR ELECTRIC LAMPS.

SPECIFICATION forming part of Letters Patent N o. 675,398, dated June 4, 1901.

Application filed February 28| 1901. Serial No. 49,214. (No model.)

To @ZZ whom t may concern.-

Be it known that we, EDWIN J. MOALLIs- TER, ALMOND. PAGE, and LoUIs C. WERNER, citizens of the United States, and residents of Newark, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Adjustable Protecting Devices for Electric Lamps, of which the following is a specification.

Our invention is an improvement in electric lamps employed for signs, letters, iigures, and designs, such as that shown and described in the Letters Patent issued to W. F. Brewster December 11, 1900, No. 663,532.

The object of our invention is to provide a cheap and effective adjustable device to pro,- tect exposed lamps and their connections from rain, snow, and dampness.

We provide a rain or weather guard for each lamp, consisting of a cylinder of sheet metal, like brass, (but any suitable material may be used.) One end of this cylinder encircles and is adjustably supported upon the lamp socket or receptacle. There is a clamping device to fix and hold the cylinder in position on the socket. .f The other end of the cylinder is turned inward and stands at an acute angle, its edge being resilient. This edge is circular and is capable of engaging with the cylindrical tapering surface of the lamp-globe, while the line of contact with said globe may be caused to vary by sliding the cylinder up or down upon the socket or receptacle, thus providing for adjustment to lamps having globes of dierent diameters.

The accompanying drawing illustrates our invention. It is a vertical central section of the lamp-socket, receptacle, and weatherguard.

s represent the lamp-socket a'nd receptacle, and 2O is an incandescent lamp having two termin alcontacts 21 22. In the socket s there are contacts 23 and 24, engagingwith the contacts 25 and 26 in the part t. There is a central perforation in the parts s t, through which passes the bolt 27, clamped by the nut 28. Thus the two parts s and t are mechanically there is a clamping device having ears like 31, with a bolt 32, so that we may slide the cylinder up and down on the socket s and clamp it in any position with the screw 32. There is an inturned ilange or collar h, Xed to or forming part ofl the cylinder at its opposite end. The internal edge of this collar h is slightly resilient and presents a circular outline, so that it may be caused to closely engage the surface of any lamp globe or globes differing in diameter Within reasonable limits.

What we claim, and desire to secure by Letters Patent, is

l. A socket or receptacle for an electric lamp and a lamp, combined with a cylindrical section of sheet metal having its upper edge bent inward to engage the surface ofthe lampglobe and means for clamping the cylinder in position.

2. In combination a lamp, a socket or receptacle therefor, a weather-guard consisting of a sheet-metal cylinder having its upper edge folded to engage the lamp-globe and means for fixing said cylinder in position.

3. The combination yof an incandescent lamp, a suitable support therefor, a weatherguard consisting of a cylindrical section of sheet metal having its free edge turned inward to engage the lamp-globe and means for adj ustably iixing said guard in position.
