' LAM P-BURNER.

QPECIFIGATION forming part of Letters P Application filed August s, 1903.

To all whom it may concern.-

Beit knownthatLWTLLIAM S. HAMM, a citizen of the United States, residing at Chicago,

in the county of Cook and State of Illinois,

provements in Lamp-Burners, of which the followi part thereof.

This invention is designed for use with such switch, semaphore, and other stationary signal-lamps employed in railroad signaling as are intended to be supplied with oil only at long intervals-say from seven to eight days-- I and to remain without attention such as is required for trimming of the wick, cleaning of the burner, &c., for an equal length of time. In an applicatio date herewith in the names of John A. Mosher and William D. Legge, Serial No. 168,092, a lamp-burner is described and claimed adapted for such service, and in the use of such a burner it becomes necessary that the wick which, as stated, remains unexamined for so long a period shall be maintained in a constant position and prevented from being jarred down while the burner is in service. In a lamp of this character the flame from the burner is smaller than is ordinarily found in signallamps, and therefore more easily'influenced by the position of the wick, the .size of the flame being susceptible of reduction upon the slightest variation in the height of the wick. For this reason it is necessary to maintain a specified or determined position of the wick during the entire length of service. Heretofore attempts have been made to lock the wick in predetermined position, but so far as I am advised not by the means employed by me, which permit of the convenient reaching of the lock for operation without the removal of the burner from the font. -In my invention the locking-pin is so located with respect to the burner that said pin may be disengaged from the wick by the use of one hand while the other is employed in raising or lowering the wick.

In the accompanying drawings, Figure 1 is a side view of a lamp-burnerembodying my invention. Fig. 2 is a plan View of the same,

away to better show my improvement. Fig. 3 is a vertical section. Figs. tand 5 are details'hereinafter described. Fig. 6 shows a modification.

The base part 0 f the burner is represented by 1,it having a threaded portion 2 of re duced diameter for attachment to the oil-font. The wick-tube is shown by 3, it passing centrally through the portion 1, the latter being closed at its bottom 4 and having a domed top 5, the wick-tube extending through and above the latter, as shown. Surrounding the wicktube and secured to the domed top 5 is the lower and stationary part 6 of the burnercone, the upper and removable portion of said cone having perforated sides and being shown by 7. The two parts 6 f the cone are detachably connected, preferably by means of bayonet-joints. The top of the removable portion 7 of the cone is provided with a tubular tip 10, the upper portion of which is cup-shaped, as shown at 11, the lower end of the tip extending to within a short distance. of the top of the wick-tube 3. The chimneygallery is shown by 12, it being supported by the base 1 of the burner through the medium of the chimney-holding wires 13. burner as is here outlined is described and claimed in the above-mentioned joint application of Mosher and Legge. The wick-raising shaft 16, with its ratchet or star wheel 17, is fitted to and journaled in the base in the ordinary manner.

In the wick-lock, which constitutes the invention herein claimed, a pin 22 is supported by the base 1 and a hooded bracket 19, projecting from the base, the pin being capable of sliding movement. A spiral spring 20 is confined between the outer wall of said hood and a collar 21, mounted upon the pin 22, the latter having a button 23 on its outer end adapted to be readily grasped by the operatcr. The inner sharpened end of the pin is adapted when in normal position'to project partly through the wick-tube 3, so as to enter the wick 24:, the pin being forced inwardly by the action of the spring 20. The pin 22 preferably stands in the plane of the axis of the wick-adjusting wheel 17 and at a right angle thereto. It will be seen that the pin 22 is at all times provided with at least two bearings, one being in the outer end of the hooded bracket 19 and the other in the Wall of the base 1, so that the pin is always maintained in horizontal position, it difiering in this respect from a certain form of wick-lock the inner or operative end of which is adapted to be given an up-and-down movement for raising the wick. The object in hooding the -volving invention bracket 19 is to protect the portion of the pin 22 that extends beyond the base 1 and the spring from the action of the elements. In Fig. 6 the pin is shown as adapted to engage the teeth on the wheel, thus preventing its turning and providing a double lock for the wick-'6. e., by means of the pin and also the teeth of the wheel.

The operation of my invention will be readily understood from the foregoing, and it will be seen that the locking-pin 22 may be withdrawn from the wick 24 while the operator with the other handadjustsits height. Figs. 4 and 5 show the locking-pin and its adjuncts detached from the burner.

I do not restrict myself to the exact details of construction, combination, and arrangement herein set forth, it being obvious that minor variations thereof not involving the exercise of invention may be made by the skilled mechanic, and such departures from what is herein described and claimed not in- I consider as within the scope and terms of my claims.

Having thus described my invention, I claim 1. In a lamp-burner, a base having a pinhole in its side, abracket projecting from said base having an opening in line with the pinhole therei i, and a Wick-tube passing vertisentrally through said base and i caily and provided with a pin-hole, combined with a slidable pin supported by said bracket and base and adapted to enter the hole in the wick-tube, a collar on said pin, and a spiral spring confined between the outer wall of the bracket and said collar, substantially as set forth.

2. In a lamp-burner, a base having a pinhole in its side, a hooded bracket projecting from said base having an opening in line with the pin-hole therein, and a wick-tube passing verticallyand centrally through said base and provided with a pin-hole, combined with a slid'able headed pin supported by said bracket and base and adapted to enter the hole in the wick-tube, a collar on said pin, and a spiral spring confined between the outer Wall of the bracket and said collar, substantially as set forth.

In a lamp-burner, a base, a wick-tube extending vertically through said base, and a wick-adjusting shaft supported by said base and provided with a ratchet or star wheel passing through a slot in the wick tube, combined with a bracket extending from the base at a right angle to the Wickadjusting shaft, a headed pin supported by said bracket, base and wick-tube so as to have a sliding movement, the inner end of said pin being adapted to perforate the wick and engage with said ratchet or star wheel, and means for normally forcing said pin into such position, substantially as set forth.

In testimony whereof I hereunto set my hand and seal.
