pecially to headlights provided with colversV t is to close the o ening by fluid-pressure. well knownV t at inthe operation of singletrack railway-lines when one train is sidetracked to 'permit the passage of another train it is necessary to extinguish the head-' light'of the side-track locomotive or to, cover Athe opening. The headli hts commonly in use are provided with a s eet-metal hinged cover which is closed by an operatlve' oing zo from the cab along the running-boar to the front of the locomotive and closing the cover byhand. In inclement weather. the` closing of the headlight-cover becomes a veryl disagreeable task and is therefore sometimes omitted, to the confusion and possible accident to trailic.

It is the object of my invention to provide a headlight-cover Iand means whereby the cover may be opened and closed from the cab by the use of steam-pressure from the boiler or air-pressure from the storage-tank.

A further object of my invention is to provide a huid-operated cover' for headlights which may be readily appliedto headlights of the ordinary construction and inl common use. l

With these and other'objects in view the present invention consists in the combination and arrangement of parts, as will be herein-- after more fully described, shown inthe accompanying drawings, and particularly pointed out in t e appended claims, it being understood that changes' in the form, proporltion, size, and minor details may be made within the scope of the claims without departing'from t e spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 1s a view in side elevation of a locomotive upon which a headlight is mounted provided with my improved luid-pressure-operated cover, with the cab shown in section, with a means for operating the cover by controlling the fluid-pressure from the cab. Fig. 2 is a View in side elevation of my improved headlight-cover mounted upon a headlight, showing the'operatingarrange cylinder in section andl the attaching-band broken away. Fig. 3 is a viewin front elevation ofa headlight with'my improved cover mounted thereon.

Like characters of referencedesignate corresponding parts throughout the several views. y

In its preferred embodiment my headlightcover comprises a band 1, proportioned to be laced upon and embrace a bezel of a headight-glassand provided at a plurality of points with means for clamping the bezel, as the set-screws 2. The upper part of the band 1 is provided with a segmental cover 3, permanently secured .thereto and provided with perforations 4 in the form of gures to indicate the number of the locomotive bearing the headlight. To the 'segmental cover 3 is 'hinged a cover 5, pro ortioned to cover that portion of the headlig t-glass not covered by the segmental cover 3 and carried upon horizontal y-disposed hinges 6. At any convenient point, as the upper portion'of the segmental latef3, may be disposed a brace 7,

d to limit lthe u ward'movement of. the hinged cover 5, so t at when contacting with the brace, 7 thehinged vcover 'is disposed in` approximately a horizontal plane,

To the side of the headlight-body is secured in any convenient manner a cylinder 8, within which is disposed a reciprocating piston 9 and a coiled spring 10, arranged to liold the piston normally at the extreme of its inward movement. A piston-rod 11 extends from the piston 9 through the 'end of the cylinder S, and a link 12 connects the piston-rod 1] with a crank-arm 13, rigidly'secured to the hinge-rod of the dover 5. A pipe 14 communicates with the cylinder'S' and with a-source 95 of' Huid-pressure, as the storage-tank 15, and in its course passes through the cab of a locomotive. The pipe may be` rovided with any approved means for contro ling the ilow of a Huid within said pipe, as the cock 16, arranged to permit the iow of fluid. through the pipe 14into the cylinder 8, and the bleeder 1 7,

' to permit the escape of the compressed iiuid.

The operation of myimproved headlightcover is as follows: The several parts will be normally arranged as shown in the several i'gures of the drawings, with the cover member 5 held in a raised position in contact with thebrace 7 by the tension 1of the spring 10. When it is deslred to close the cover, the cock 16 may be opened, permitting luid from thc source of supply to oW through the pipe 14 IOO into the cylinder 8 and acting therein uponl l the piston9will produce a-longitudinal rnovement of the piston against the tension of the spring, causing the crank 13 to move about `t e hinge 6 as a center to the position 13, closing the cover 5, as indicated at a. So long as it is desirable to maintain the cover in a closed osition the iiuidressure may be maintaine within the cylin er. desired to open the cover 5, the cock 16 is closed and the bleeder 17 opened, permitting the escape of' the fluid from the piston 8 under the tension of the spring 10, and the strain exerted by the spring will return the cover to its normal position.

I/Vhile I have shown the movable cover v plete disk and hinged in any convenient manner. While I have shown the cylinder 8 as being obliquely disposed upon the body of the Aheadlight, thus exposing to view the illuminated numbers which are almost universally carried b'y headlights, it is obvious that the cylinder may be arranged horizontally along the upper part of the headlight-body or may be arranged vertically along the front edge and that numerous other changes may be lmade in the form and arrangement of the several members constitutingv my improved headlight without departing fromA the spirit of my invention or the scope of the'claims.

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

1. In a deviceof the character described, a band adapted to embrace and be secured about the bezel of a locomotive-headlight glass, a egmental cover permanently secured thereegaovable coverhinged to the segmental civerarrd-normally open, a cylinder, a piston disposed within the cylinder, a lever rigidly connected to the hin ed cover, a link pivoted to the said lever an to the piston, a source of Huid-pressure, and means for admitting the iiuid-r pressure to the cylinder to close the said hinged cover.

2. In a device of the class described, the combination of a headlight, a source of iiuidpressure, a hinged coverv adapted and arranged to be removably secured to the bezel When it is piston o ens and closes the cover,v a spring mounte within the cylinder and disposed to hold the piston at the extreme of its move- `ment, pipes connecting the cylinder and source of iiuidressure, a valve dis osed to Iadmit Huid un er pressure' to the cy inder to move the piston and close the cover, and means to permit the escape oi the air from the cylinder to permit the spring to act.

'3. The combination with a headlight of a removable cover consisting of a band and means for securing said" band to the bezel of said headlight, a cover hinged to the band and an arm to limit the swin of` said cover, a cylinder and motive-Huid4 lnlet thereto, a springpressed piston within the cylinder, a lever-arm attached'to the hinged cover, and

a link connecting said arm and the piston- 4,' The combination witha headlight 'of a removable band and screws for securing said band tothe bezel of the headlight, a cover lover the band having a hinged portion, an

arm projecting from the cover to limit the movement of the hinged-portion., a cylinder secured to the headlight and connected with an air-drum, means for admitting air to said cylinder, a piston within the cylinder, a leverarm attached to the hinged cover, and a link connecting said arm and the piston-stem.

I 5. The combination with a locomotive`..

headlight of a band and means for securing the same to the bezel of the light, a cover vover the band having a stationary and a hinged portion, means for openingxthe hinged portion upward away from the lig t, and perforations in the stationary portion of the cover identifying the locornotlve.l

In testimony whereor1 I afiix my signature in presence of two witnesses.
