IMPROVEMENT IN LAM P-COLLARS.

Specilication forming part of Letters Patent No. 4l,795, dated March 1, 1864.

To all whom it may concern:

Be it known that I, ALBERT TAPLIN, o the city of Providence, in the county of Provdence, in the State of Rhode Island, have invented an Improvement in Lamps and I do hereby declare that the following is a full and correct description thereof, reference being had to the accompanying drawings, forming part of this specication, and to the letters of place between the common lamp-top and the burner that holds the wick, to afford easy access to the inside of the lamp for the purpose of llingit.

The collar is made of two parts, A B, which are shown in Figs. 3 and 4. These parts are punched out ot' sheet metal, and arepressed or swaged into the proper shape by means of dies. Fig. 4 shows the lower part of the co1- lar B, and has a projection, C, left on one side to form a catch, and also a projection, a, on the opposite side to form the claspjoint. This last projection is turned up, and has a narrow slot, x, cut in it to receive the part of the clasp on the upper part of the collar A. A portion of the metal is left at o to be slotted to receive the spring D. This part of the co1' lar has a screw-thread cut on its lower end, s, to screw into the top of the lamp.

Fig. 3, which represents the top part, is made with a projection at c of the proper size to go into the slot :vin the lower part, B. This forms the other part of the clasp, and is turned up so as to catch into the lower one. A

screw on the lower end ofthe burner or wick# holder.

A spring, D, is fastened to the upper part, A, and slides through the slot o in the inside of the lower part. This spring is to hold the upper part of the collar up while open, and also to keep it from going too far back, the lower end of the spring being bent over to prevent it from coming entirely out of the slot.

The clasp-joint a c can -be made at much less cost than the hinge-joint, as it requires less metal and labor in its construction.

Y The mode of operating it is simplyas follows: The lower part of the collar;l B is screwed into the ordinary top of a lamp, and the burner or wick-holder is screwed into the upper part of the collar. When it becomes necessary to fill the lamp, the collar is opened'by tipping back the burner in the direction of the clasp unt-il the bent end ot' the spring D brings up against the side of the slot o, where the spring` will hold it, so that it cannot be jarred or shaken down while the oil is being poured into the lamp. By bringing the burner back to place the collaris shut, and the catch l in front holds it rmly in that position.

Having thus described my improvement i and the mode of operating it, what I claim as my invention, and desire to secure by Letters Patent, is this:

The combination of the upper and lower parts of the collar with the clasp-joint and spring D, when constructed and operating substantially as described, and for the purpose set forth.
