sQCOMOTlVi Original No. 143,550, dated October .1, 'nm.

To all whom it may concern;

-Be it known that I, WILLIAM WESTLAKE, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Locomotive Head- Lights, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a locomotive head-light containing my improvement; Fig. 2, a vertical cross-section of the same Fig. 3, a plan view of the revolving platform and the lamp and reflector being removed; Fig.. 4. a similar view of the same mate, with thle platform turned to bring. the re ector n g ietqasam'e rrt 0.5m for lightffigfah ig. 5 a cross-iction 'bn' the line at a: of Fig. 3.

Prior to the present invention locomotive head-lights have been constructed and arranged so that the entire case in which the lamp and the reflector were inclosed could be ght or left for the purpose of keeping the light on the track when the locomotive is passing round curves; but, so far as known, there was no construction by which the lamp and its reflector could be partially or lved independently of theinclosing-case. The usual construction has been to mount the lamp and its reflector upon a sliding base, which was pushed into position in ways in the bottom of the case and retained in such position until it was withdrawn. There was no means provided by which the reflector while in the case could be adjusted to face otherwise than directly to the front. It followed from this construction that when it was desired to reach the lamp to light it, or to reach the face' of the reflector for any purpose, it was necessary to withdraw the lamp and the reflector either partially or wholly through the side door of the case,.and then to push them back to their proper position. v

The object of the present invention is to provide means by which the lamp and the reflector of locomotive head-lights can bemore convenientlyreached'; and the improvement 'tionnthaplattbzm consists in arranging the lamp and its reflector so that they can be turned or revolved within the"caee; a lamp and its reflector, in combinaarraugedtorevolve within HEAD-LIGHT.

the case of a locomotive head-light; a revolving' lamp and reflector, in combination with an aperture or arm-hole. in the inclosing-case, and' an aperture or arm-hole in the case of a locomotive head -light provided with an elastic covering. A represents the case of a head-light; B, the window in front of the case for the transmission of the light; G, the side door, provided with the usual hinges and fastening; D, a slide for closing the aperture or arm-hole in the door (3; E, an elastic yielding covering for the arm-hole; F, reflector; G, oil-reservoir; H, supports for oil-reservoir; I, revolving platform, upon which the lamp and reflector are E L0 1.I1ted;TJ, .slidinghase-plate K, covered recess to permit the tnrniugL f "the. oil-reservoir when the case. is not otherwise sufficiently large; a, pivot upon. which the platform I turns; b, spring or spring-bar; a, catchpin; d, holesiu base-plate J for locking or holding the platform I f, point of attachment of the reflector; g, burner connected with who to oil-reservoir, and h a wire or hook at the side of the burner forholding the chimney while lighting the lamp.

The case A and window B may be made in the usual form and of any suitable material. The recess K may be omitted-whenever the case is of sufiEicient capacity to permit the lamp and its attachments to revolve; but in applyingthis invention'to old lamps, whose reservoirs projected rearward to a considerable extent, it will oftentimes be found necessary to make the case wider or deeper, and the attachment of this recess K is a convenient way of accomplishing it.

L is a wind-break placed on the top of the case A, over or around the smoke-passages.

The reflector, oil-reservoir, and burner may be arranged to operate in the usual way. The revolving-platform I is pivoted at a to the base-plate J, and may be arranged to turn or revolve to such an extent as to bring the lamp and reflector to the required position. When turned to the position shown in Fig. 4 of the drawings, the arm inserted through the armhole in the door 0 can pass the edge of the reflector, and the lamp can be easily reached for the purpose of lighting it, and the operator, by looking through the window in front;

' can direct the movements of his hand in lighting or adjusting the lamp.

V It will be observed that when the reflector is turned to face toward or to the rearward of the door 0 the wall of the reflector will be interposed between the lamp and the window B, and the transmission 0" the light through the window will be prevented. This convenient adjustment may be availed of whenever it is desired to conceal from the directors of other trains the presence of a locomotive or train at any special spot, as is often the case; and it may also be employed with advantage to bring the reflector or burner into the position where they can be readily cleaned through the open door 0, thus saving the necessity of whollyor partially withdrawing the reflector and lamp from their inclosing-case. The spring b, provided with catch 6, to take into holes dproperly located in the base-plate J, furnishes convenient means for locking the revolving platform in the desired positions.

For the purpose of adjusting the height of the wick without turning the lamp and its attachments into position, a wick-regulator may be placed inside of the reflector, and it will be found convenient to provide a match-safe and rough surface for lighting matches inside of the case A, near the arm-hole.

The covering or diaphragm E for the armhole is made of india-rubberprovided with slits, as shown, so as to permit the passage of the hand and arm through it, and so that it will fit against the arm and prevent the ingress of wind when lighting the lamp. It

may, however,

lows, or in such other manner as will permit the insertion of the hand and arm without admitting wind.

The base-plate J, to which the revolving platform I is pivoted, may be made to slide in ways constructed in the bottom of the case by which means the lamp and reflector can be easily introduced into and withdrawn from the case, and by which they can be fixed in their proper position when in the case.

What is claimed as new is- 1. In a locomotive head-light, the combination of areflector' and a revolving support,

whereby a partial or complete revolution can be given to the reflector independently of the inclosing-ca'se.

2. The combination, in a locoihotive headlight, of a revolving platform with a lamp and its reflector mounted on such platform, substantially as and for the purpose described.

3. The combination. in a locomotive head light, of a revolving lamp and its reflector with an aperture or arm-hole in the inclosingcase, substantially as and for the purpose described 4. In the case of a locomotive head-light,

an arm-hole or aperture, in combination with an elastic covering, substantially as and for the purpose set forth.
