HEADLIGrI-IT-COVER.

Specification of Letters Patent.

Patented Jan. 14,1913.

Application filed May 1G, 1912. Serial No. 697,719.

To all whom t may concern:

Be it known that I, CHARLES H. CHAMBER- LxiN, a citizen of the United States, residing at Bellefontaine, in the county of Logan and State of Ohio, have invented certain new and useful Improvements in Headlight-Covers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in covers for locomotive head-lights.

One object of the invention is to provide a cover for locomotive head-lights having an impr'oved construction and arrangement of hood adapted to be raised and lowered over the light to cover or to expose the same when desired.

Another object is to provide a headlight cover having an improved construction and arrangement of operating mechanism adapted to be actuated by air pressure and which is arranged entirely within the head-light box or housing.

Vith these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings; Figure 1 is partly a side view and partly a vertical sectional view of a head-light showing my invention applied thereto and in an inoperative position; Fig. 2 is a vertical sectional -view of the same showing the invention in an operative position, or covering the light; Fig. 3 is a detail perspective view of the saddle for supporting the operating bar of the hood.

Referring more particularly to the drawings, 1 denotes the lamp box 0r housing of a locomotive headlight, 2 denotes the lamp arranged therein. The burner 3 of the lamp has a chimney l and a reflector 5. These parts may be of the usual or any desired construction.

Adapted to be engaged with the chimney 4t of the lamp is a hood 6 which is preferably in the form of a cylindrical tube. The hood G is adjustably secured in the forked or bifurcated outer end of a supporting and operating bar or lever 7 by means of headed screws Sprojecting laterally from the opposite sides of the hood and which are engaged with slots 9 in the forked ends of the bar 7 as shown. By thus attaching the hood to the bar 7 it will be seen that by loosening the screws 8 the hood may be adjusted on the bar to adapt the hood to the position of the chimney whereby the hood may be readily engaged with tlie chimney.

. The bar 7 is secured to and supported at its inner' end in a saddle 10 in the form of a channel shaped bar the outer end of which is slidably engaged with and guided between a pair of guide bars 11 secured at their lower ends to a rib 12 formed on one side of a compressed air cylinder 13 hereinafter described. On the outer sides of the saddle 10 where the same engages the guide bars 11 are pairs of guide lugs 14 which engage the opposite edges of the guide bars 11 and form additional guiding means for the saddle l0 when reciprocated in a manner hereinafter described. The inner end of the bar 7 is preferably secured to the saddle by an attaching bolt 15 which is inserted through the end of the bar and engaged with apertured ears 16 on the inner end of the saddle 10 as shown. By pivotally connecting the inner end of the bar 7 to the end of the saddle as herein shown and described it will be seen that should the hood be slightly out of alinement with the chimney and should strike the same or be brought into engagement with any other obstruction that the bar 7 will be swung upwardly thus preventing any of the parts from b eing broken or damaged.

Arranged in the cylinder 13 is a piston 17 `the rod 18 of which projects upwardly connected with an air conducting pipe from the air reservoir of the locomotive or other suitable supply. On the lower end of the cylinder 13 is a reduced extension 2l having therein a coiled spring 22 one end of which is engaged with the lower side of the piston 17 and the opposite end with the end of the extension 21 whereby the pressure of the spring is applied to the pist-on to force the same upwardly in the cylinder 13 thereby projecting the piston rod through the upper end of the cylinder. The piston rod when thus projected will raise the saddle 10 between the guide bars 11 thereby carrying the bar 7 and-the hood 6 upwardly, disengaging the hood from the chimney and exposing the light. As long as there is no air pressure in the upper portion of the cylinder the spring 22 will hold the parts in their elevated position for exposing the light. lVhen, however it 'is'desired to cover the light, compressed air is turned into the cylinder through the nipple 19 thereby forcing the piston 17 downwardly against the pressure of the spring 22 thus retracting the piston rod 18 and lowering the hood G over the chimney and covering the light.

The cylinder 13 has secured to its rear side a reinforcing plate 23 to rwhich are secured stud bolts 2st, said bolts projecting through the rear side of the lamp box and having engaged therewith clamping nuts 25 whereby the cylinder and other parts of the device are irmly secured to the rear side of the box. By thus arranging the device it will be seen that the same is disposed entirely within the lamp box and is thus protected from the weather. It will be also noted that in constructing the parts as herein shown and described the same are under perfect control of the engineer or iireman in the cab of the locomotive, and may be quickly operated to cover and uncover the light when desired.

From the foregoing description taken 1n connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is;

1. The combination with a head light of a hood supporting and operating bar, a light covering hood adjustably connected to one end of said bar, a slidably mounted saddle, means to pivotally connect the opposite end of said hood operating bar to said saddle whereby the outer end of the bar and the hood is adapted to swing upwardly when the hood is brought into engagement with an obstruction, fluid pressure operated means connected with said saddle. whereby the latter and said bar is lowered to engage the hood with the light, and a spring engaged with said pressure operated means whereby the same is projected to raise said saddle and bar and thereby disengage the hood from the light.

2. The combination with a head light of a hood adapted to be raised and lowered' over Vthe light whereby the latter is uncovered and covered, a fluid pressure cylinder, a piston slidably mounted therein, a piston rod connected with said piston and projecting upwardly through the cylinder, al slidably mounted saddle secured to the upper end of said piston whereby when compressed liuid is admitted to the cylinder the piston will be retracted and the saddle lowered, a hood supporting and operating bar secured to said saddle and connected with said hood whereby the latter is lowered when said piston and saddle are lowered, a iiuid pressure inlet nipple connected with the upper end of said cylinder whereby liuid pressure is admitted thereto to retract said piston and lower the hood, and ay spring arranged in said cylinder to engage said piston whereby the latter is projected to aise the hood when the fluid pressure is released from the upper end of the cylinder.

3. The combination with a head light comprising a lamp box, having therein a lamp provided with a chimney, of a tubular hood adapted to be lowered and raised over said chimney to cover and uncover the light, a fluid pressure cylinder arranged in said lamp box, a rib on said cylinder, parallel guide bars secured to said rib, a saddle slidably engaged with said bars, a piston ar- 'anged in said cylinder, a piston rod projecting through one end of the cylinder and having an operative connection with said saddle whereby when the piston is projected and retracted, the saddle will be raised and lowered between said guide bars, a hood supporting and operating arm pivotally connected at one end to and having an operative engagement with said saddle, said bar having a forked outer end provided with longi` tudinally disposed slots, means to adjustably secure the hood in the forked slotted end of the bar, a fluid conducting nipple connected with the upper end of the cylinder whereby compressed air is admitted to the latter to retract said piston and thereby lower the hood over the light, an extension on the cylinder, and a piston projecting spring arranged in said extension whereby' the piston is projected to raise the hood and uncover the light.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CHARLES H. CHAMBERLAIN.
