LOCOMOTIVE-HEADLIGHT.

SPECIFICATION forming part of Letters Patent No. 496,276, dated April 25, 1893.

Application filed October 18, 1892 Serial No. 4491 (N0 model-l T0 on whom it may concern:

Be it known that I, THOMAS E. OWENS, a resident of Marshall, in the county of Harrison and State of Texas, have invented certain new and usefullmprovements in Locomotive Headlights; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to locomotive head lights and is applicable to so-called independent reservoir lamps. The conduit by which the reservoirand burnercommunicate is liable to be obstructed with sediment which not only interferes with the suitable flow of oil but corrod es the metal and necessitates repairs.

The object of the invention is to provide a convenient and inexpensive receptacle for such sediment which will permit of its easy removal, and it consists in the construction hereinafter described.

Figure 1 is a side elevation partly in section. Fig. 2 is a partial rear elevation. Fig. 3 is a cross section of the oil pipe and receptacle on the line 33 of Fig. 1.

Numeral 1 denotes an Argand burner provided with a wick raiser both of usual form and 2 is an oil reservoir.

3 denotes a pipe or conduit by which the interior of the reservoir and the wick space of the burner communicate. The reservoir mouth of this pipe is provided with a valve seat 4, and 5 is a valve adapted to hermetically close it when desired. The valve stem has a screw threaded connection with a plug 6 secured to a frusto-conical sleeve or boss 7 made fast on the top of the reservoir.

8 is a milled head of the valve stem situated below the arched reflector-support 9.

10 is an approximately frusto-conical sleeve surrounding the vertical member of the pipe 3 and rigidly secured both to the pipe and reservoir to strengthen their connection and 11 is a brace. The under side of the horizontal member of the pipe 3 is cut away and adjacent to the metal edges surrounding the opening thus made is secured a flattened approximately oblique frusto-conica'l receptacle 12 having a tubular mouth 13 adapted to receive a screw plug 14. The receptacle 12 is preferably secured both to the pipe and to the exterior of the wick tube by soldering or otherwise substantially in the manner illustrated, whereby the connection of the pipe and tube is strengthened.

The opening in the pipe covered by the receptacle extends by preference to the wick tube the exterior of the outer wick being in practice exposed directly to the oil in the pipe 3 and in receptacle 12 and the sediment in such oil being free to settle and fall down theinclined bottom of the receptacle from which it can be removed at will through the tubular discharging mouth whenever the screw plug is taken out. But prior to such operation the valve 5 will be tightly closed upon its seat if there is any oil in the reservoir.

I am aware that sediment receptacles have been attached to vapor burners and to pipes adapted to supply oil to burners and I do not claim broadly such devices but only the construction herein pointed out. My receptacle has a length much greater than the diameter of the supply pipe and communicates with said pipe by means of a long slot which together with the receptacle communicates with the wick tube and it is provided with an inolined bottom that guides sediment from the interior of the wick tube to the laterally situ ated openingclosedby a removablescrew plug. This construction gives enlarged capacity to the receptacle, adapts it to receive sediment from the wick tube and also'to drain the same and strengthens the connection between the pipe and tube. The connection between the pipe and reservoir is strengthened by the sleeve and brace before described the whole construction giving increased capacity for separating sediment and at the same time bracing and firmly joining the parts. The latter function is secured by fastening both the slotted pipe and receptacle to the wick tube as well as by the use of a brace and flaring sleeve. This construction is of importance because it constitutes the sole support of the oil reservoir and reflector. The'holder for the latter is arched to provide suitably for the head of the valve stem which is protected thereby. The valve has a raised seat immediately about the exit from the reservoir whereby a trap for heavy sediment is formed in the latter.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-

l. The combination of the reservoir, the wick tube, the communicating pipe supporting the reservoir said pipe having a slot in its bottom extending to the wick tube, the sediment receptacle attached to said pipe over its slot and also to the wick tube whereby the connection of the reservoir and wick tube is strengthened, and a valve to close the communication between the reservoir and pipe, having a seat in the bottom of said reservoir and provided with a stem extending through its top, substantially as set forth.

2. The combination of the reservoir, the wick tube, the communicating pipe having a flaring supporting sleeve 10 and brace 11 and supporting the reservoir said pipe having a slot in its bottom extending to the wick tube, the sediment receptacle attached to said pipe over its slot and also to the wick tube whereby the connection of the reservoir and wick tube is strengthened,and a valve to close the communication between the reservoir and pipe, having a seat in the bottom of said reservoir and provided with a stem extending through its top,substantially as set forth.

3. The combination of the reservoir, the wick tube, the communicating pipe having a flaring supporting sleeve 10 and brace 11 and supporting the reservoir said pipe having a slot in its bottom extending to the wick'tube, the sediment receptacle attached to said pipe over its slot and also to the wick tube whereby the connection of the reservoir and wlck tube is strengthened and avalve, to close the communication between the reservoir and pipe, having a seat in the bottom of said reservoir and extending above the same to form a sediment trap and provided with a stem extending through its top and an arched reflector holder also supported upon the reservoir and pipe, the said valve stem having a milled head immediately beneath said arch, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
