9 Claims. (Cl. Mil-11.2)
This invention relates to a headlight for a mining machine which in one aspect of the invention is a combination headlight and tail light.
An object of the invention, therefore, is to provide an improved headlight and tail light particularly of a flame proof type for'use on a mining machine or other mining apparatus.
A further object of the invention is to provide an improved flame proof headlight.
Still another object of the invention is to provide a headlight including improved cushioning means for supporting a reflector for a combination light bulb and reflector such as the sealed-' beam light bulb for automobiles.
Other objects of the invention will appear hereinafter the novel features and combinations being set forth in the appended claims.
In the accompanying drawings,
Fig. l is a transverse sectional view through the headlight of my invention;
Fig. 2 is a rear'view thereof; I
Fig. 3 is a top plan view thereof with parts shown in section; and
Fig. 4 is an enlarged partial sectional view taken on the line 4-4 of Fig. 3, looking in the direction of the arrows.
The headlight of my invention is designed particularly for use in gaseous coal mines though in some of its broader aspects it involves features used in non-gaseous mines and for general utility.
- Said headlight is actually a combination headlight and tail light and in a mining machine, such as a locomotive, there will be two such lights employed and the tail light bulb of one of them nation headlight and junction box which is flame proof and thus usable in a gaseous mine since means are provided for running a cable from the housing thereof to an extraneous light in the nature of a searchlight or flashlight.
The device comprises a casing or housing ll having an open internally threaded front end preferably formed as a steel casting though other material may be employed. Forming a .part of the casing or housing II is a removable front ring or rim Ii which is threaded into the open front end of the main casting of said housing ll. Ring l I is provided with a front opening which is closed by a heavy glass lens I! held in place by a snap ring it which snaps into a groove in the rim Ii. The lens I! is provided with a peripheral lead beading ll or other sealing means which provides 2 a flame proof seal between its periphery and the ring portion ll of the casing or housing ll. Bubstantially midway between the front and back of the housing Ill there is a peripheral groove ll formed on the interior of said housing II by rear peripheral flange I. which forms a forwardly facing abutment or peripheral shoulder adjacent the open end of the main casting of housing I0 and the rear face of the rim Ii which forms a rearwardly facing abutment or peripheral shoulder. Mounted in said housing I ii is a combination light bulb and reflector l'l, or what is commonly known as a sealed-beam light bulb or lamp. Said sealed-beam bulb is provided with an integrally formed peripheral rim II at its greatest diameter which is particularly effective to cooperate with cushioning or damped-resilient mounting means of snarled material interposed between said rim II and the groove II. This cushion or dampedresilient mounting of snarled material is prefer- 'ably in the-form of a packing I! of metal wool such as turnings or curlings of" steel, brass or bronze wool, which possess internal friction and provides a snubbing eflect toprevent high frequency vibration or aggravation from vibratory shock in said bulb or lamp. Said packing II is preferably formed in the shape of a pre-formed ring which is fltted into the groove llbetween the abutments or-shoulders provided by the peripheral flange I andthe ring Ii. The packing I! encases or surrounds theperipheral rim ll of the light bulb 0r reflector ILancfis compressed about therim i8-andbetween-the-shouldcrs or abutments of flange i6 and ring H and the outer wall of the main casting of the casing or housing ll whichabut it when the ring or rim II is screwed tight to provide a flame proof fitting between itself and the other portion of the casing or housing ll. This particular type of packing II is extremely desirable in a mining machine headlight since such machines are subject to severe shock such as the dropping of lumps of coal thereon and it is desirable that this shock be absorbed to a large extent without being transferred to the bulb II. It is desirable that this flexible mounting be of damped resiliency so that any vibration transferred to the bulb ll will be immediately dampened out. The packing It the rim It. as viewed in Fig. 1 of the drawings, has its inner surface coated with an opaque refleeting material such as silver, nickel or chromium. The rear or reflector portion of the light bulb i1 is provided with terminals by which the filament is supported from the reflector and current is conducted thereto.
To provide the tail light characteristic of the headlight, the casing It is provided with a pair of lateral ears or projections 2|, 2| each of which is provided with an insert 22 of heavy colored glass which is closely fitted to the adjacent periphery of the casing ill and is glued in place to provide a, flame proof fitting therewith. Adequate space is provided to the rear of the inserts 22 so that light from a bulb 23 located behind the light bulb reflector II will readily pass through said inserts 22 and be visible from the outside of said lamp. It is also desirable to paint the interior of the casing l0 white to aid in reflection of light from the bulb 23. Light bulb 23 is received in a socket 24 carried by a, bracket 25 mounted on a boss formed on the rear wall of the casing I0. At its rear the casing III is provided with a conduit or cable receiving opening into which an electric cable 26 extends, there being a flame proof fitting or stuiflng box 21 formed in the casing ill to receive said cable 26, thus preserving the flame proof character of said housing Ill.
Considered in another aspect of my invention the unit is both a headlight and a junction box in that I preferably also provide another cable inlet or opening for a cable 28 leading into the housing Ill, there being a flame proof fitting or stufling box 29 cooperating therewith. The cable 28 has its conductors connected in parallel with the conductors leading to 'light bulb 23 or to the conductors leading to light bulb IT as desired. Said cable 28 may supply power to an external light such as a portable searchlight or flashlight.
From the above description it is obvious that I have produced a very rugged headlight which is preferably not only a headlight but also a combination headlight and tail light and one which is designed for rugged service and in the preferred embodiment of my invention for use. in a gaseous -mine since it is flame proof. Furthermore in another aspect of the invention the unit constitutes a combination headlight and junction box which is flameproof in character.
Obviously .those skilledin the art may make various changes in the details and arrangement of parts without departing from the spirit and scope of the invention as defined by the claims hereto appended and I wish therefore not to be restricted to the precise construction herein disclosed.,,
Having thus described and shown an embodiment of my invention, what'I desire to secure by Letters Patent of the United States is:
