HEADLIGHT.

SPECIFICATION forming part of Letters Patent No. 714,829, dated December 2, 1'902- Application filed November 11, 1901. Serial No. 81,908- (No model.)

To all whom it may concern:

Be it known that I, JAMES ROBERTSON STAN- TON, a citizen of the United States, residing at Cleburne, in the county of Johnson and State of Texas, have invented a new and useful Headlight, of which the following is a specilication.

My invention relates to certain improvements in locomotive-headlights, and has for its principal object to so construct the lamp and its casing as to permit of the lighting or adjusting the lam p-blaze from the back of the headlight box or casing wit-hout exposing the lamp to drafts, and a further object is to so construct the lamp as to permit of the lighting without the removal of the lamp-chimney.

Further objects and advantages of the invention will be apparent from a reading of the following description.

In the accompanying drawings, Figure 1 is Y a transverse sectional elevation of a headlight constructed and arranged in accordance with my invention. Fig. 2 is a similar view illustrating the adjustment of the lamp to lighting position. Fig. 3 is a rear elevation of the headlight box or casing. Fig. 4: is a sectional elevation, on an enlarged scale, of the movable lamp-chimney'support. Fig. 5 is a sectional plan view through the upper portion of the chimney-support, illustrating a modification.

Similarnu merals of reference are employed to designate corresponding parts throughout the several gures of the drawings. Y

1 designates a box or casing of the class generally employed for locomotive-headlights, the front of the box being provided with the usual glass face 2. Within the box is an oilreservoir 3 in communication with a lamp 4, arranged within a reflector 5, the construction and arrangement of the parts being in general in accordance with the present practice.

The lamp-Wick tube 6 is provided at its upper end with a vertically-adjustable chimneysupport 7, carrying a chimney 8. The chimney-support has a central tube or lining 7 tting closely around the wick-tube, and in said lining and in the shell of the chimneysupport proper are formed a number of openings 9 10, through which air may pass to support combustion. The larger opening 9 is arranged at the rear of the chimney-support in convenient position for ignitin g the wick when the chimney-support is adjusted to the position shown in Fig. 2. The walls of the chimney-support are not perforated in accordance with the general practice, the air passing through the openings 9 and 10 to the top of the wick and the smaller openings l0 ou the outer side of the tube presenting a combined area about equal to the area of the Opening 9 in orderto present an equal supply of air to all portions of the wick. The chimneysupport is provided with a carrying-arm 1l, which normally rests on the bottom of the headlight-box during the time the lamp is in use, as illustrated in Fig. 1. The lower portion of the arm is bent in such manner as to form a holding-catch 12, which may engage with a shoulder 13 at the lower portion of the wick-tube and hold said chimney-support and chimney in an elevated position, as illustrated in Fig. 2, the wick being exposed and in convenient position for lighting.

The reflector 5 may be of the usual construction; but in its central portion there is formed an elliptical or vertically-elongated opening 15, through which an ordinary match or other igniting device may be passed.

In the rear wall of the box or casing is an opening covered by a glass panel 16, forming a sight-opening, through which the height of the flame may be observed, and below said opening is a second opening 17, preferably of the elliptical form shown and normally covered or closed by a slide 18, adapted to guideways 19 on the inner side of the casing. This opening is formed for convenience in lighting the lamp, the slide being withdrawn for the insertion of the hand and arm, and in order to avoid exposing the lamp to a draft of air the front end of the slide is rounded or out away, so that it may form in connection with the wall of the opening 17 a substantially circular opening adapted to fit closely around the wrist or forearm,- and thus exclude the air.

It will be noted that the lighting-opening 9 is in the rear of the chimney-support and in such position that it is only necessary to form 'a very small opening in the reiector for the insertion of an ordinary match, avoiding the necessity of cutting away enough of the reflector-surface to permit of the inser- IOO tion of the hand or arm, such as would be necessary if the wick were lighted from the ltop of the ventilator.

At a point below the opening 17 the rear wall of the box or casing is provided with a similar opening 20, which may be covered by a slide 21 of a construction similar to the slide 18, and both slides are provided with knobs or handles 22 for convenience in opening or closing the same. The lower opening 20 is so arranged that the hand may be inserted into the lower portion of the box or casing to raise or lower the carrying-arm 11 of the chimney-support 7 or for theadj ustment of the turning-knob 23 of the wickraiser, the lnob being turned to adjust the flame to any desired extent and the height of the iiame being visible through the sightingpanel 16.- When the chimney-support is adjusted to the position shown in Fig. 2, the slide 2l is closed and the slide 18 is opened to permit of the insert-ion of a match or torch to the wick. When the wick is lighted, the chimney-support is pushed down to its normal position by passing the hand tothe top of the chimney and pressing down on both the chimney and its support. The slide 18 is then closed, and the lower slide 21 is opened to adjust the wick.

It will be observed that the openings 9 and 10 are, when the chimney-support is raised, in such position as to expose the wick, the upper walls of the openings being above the wick-tube. In order to prevent any possibility of the upper walls of the openings catching on the upper edge of the wick-tube, said upper walls are outwardly flared, as indicated at 25 in Fig. 4. t

The openings v9 and 10 may be of any desired contour, andin some cases the walls of the chimney-support may be of the perforated type, if desired. In such cases it is designed to employ only a single opening, as indicated at 9' in Fig. 5, and to cover such opening with a pivoted lid or cover of perforated material, which will supply an even and regular amount of air to the wick.

The present invention is designed for use in connection with existing types of headlights, the only changes necessary being the new form of chimney-support and its carrying-arm, the cutting of the opening 15 inY the rear wall of the reflector, and the arrangement of the three openings in the rear wall of the box or casing, as herein described.

While the construction described, and illustrated `in the accompanying drawings, presents the preferred form of the device, it is obvious that many changes may be made in the form, proportions, size, and minor details of construction without departing from or sacrificing any of the advantages of my invention.

Having thus described my invention, what I claim is 1. The combination in a headlight, of the box or casing having in its rear wall an opening in alinement with the wick-adjusting device of the lamp, a slide adapted to cover said opening, a reflector having an uncovered opening in alinement with the Wick of the lamp to permit the insertion of a lighting-taper from the rear of the reflector, a secondary opening formed in the casing in alinement with the wick and with the reflector-opening, a slide for covering said secondary opening, and a transparent panel in the rear of the casing to allow inspection of the light through the reilectoropening, substantially as specified.

2. The combination in a headlight, of the boxor casing having in its rear wall an opening to permit the insertion of the arm in lighting or trimming the lamp, a slide adapted to cover the same and having its forward edge curved to fit closely to the arm when inserted through the opening to prevent draft, guideways for supporting said slide, a lamp situated within the box or casing, and a reflector having an uncovered opening in the rear of the lamp and in alinement with the lamp wick to permit the insertion of a lighted taper from the back of the reliector, substantially as specified.

3. In a device of the class specified, a lamp having a wick-tube, a chimney-support vertically adjustable thereon and provided with lighting openings movable into alinement with the top of the wick of the lamp, and an inner tube forming part of the chimney-support, said tube being spaced from the inner portion of the chimney-support to aord a Ventilating-space and being provided with openings in alinement with those of the chimney-support, substantially as specified.

4. In a device of the class specified, a lamp having a wick-tube, a chimney-support having a side opening, an inner tube forming part of the chimney-support and guided on the wick-tube of the lamp, said inner tube having an opening the upper wall of which is outwardly flared, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

JAMES ROBERTSON STANTON.
