Application filed September 9, 1916 SerialNo. 119,291.

To all whom it may concern:

Be it known that we, lV'iLLmnrH. ASH- WORTH and JOHN C. CROUT, citizens of the United States, residing at Pelion, in the county of Lexington and State of South Carolina, have invented certain new and useful Improvements in Signals, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in signals and has relation more particularly to a device of this general character especially designed and adapted for use in connection with railways; and it is an ob ject of the invention to provide a novel and improved signal which will be operative in conjunction with the usual headlight of alocomotive and wherein an efficient reflector is employed which, when properly arranged with respect to an approaching locomotive, will reflectthe headlight thereof back to the cab in the nature of a signal light whereby the use of a lantern as now commonly employed is dispensed with.

The invention consists in the details of construction and'in the combination and arrangement of the several parts of our improved signal whereby certain important advantages are attained and the "106 is ren dered simpler, less expensive and otherwise all as will be hereinafter more fully set forth.

The novel features of, the invention will hereinafter be definitely claimed.

In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view partly in elevation and partly in section illustrating a signal constructed in accordance with an embodiment of our invention, the operating spindle or shaft being shown infragment;

Fig. 2 is a fragmentary view in top plan illustrating the connection of the disks to certain of the arms as herein included;

Fig. 3 is a sectional view taken substantially on the line .33 of Fig. 1;

Fig. 4 is an elevational view of one of the reflectors as herein disclosed, and r Fig. 5 is an enlarged fragmentary sectional view taken through one of the reflectors and illustrating in detail the facets of the convex face thereof.

As disclosed in the accompanying drawings, 1 denotes the vertical "shaft or spindle of a conventional type of switch stand and engageable with the upper extremity of said spindle .or shaft 1 is the socket 2 which is also operatively engaged with the hub mem her 3 from which extends the erably four in number.

arms 4 pref- Secured'tothe opposite sides of each of the arms 4 by the bolts 5 or the like are the concentric disks 6 which extend in ad.- vance of the outer or free end of said arms,

and disposed around the peripheries of saiddisks 6 are the housingsH. As herein embodied, each of said housings H. comprises two sections 7 provided attheir ends with the outstanding ears 8. One pair of ears is adapted to be secured to'the arm 4 as indicated at 9, while the second pair of cars has coacting therewith a conventional bolt and nut indicated at 10, whereby the housing H may be efiectively clamped-to the disks 6.

Positioned within the housingH and coacting with each of the disks 6 is a reflector 11 herein disclosed as a glass concavo-convex in form with its convex face disposed outwardly and with its concave face provided with a suitable reflector 11 preferably a composition such as employed in connection with mirrors.

The concave face of each of the reflectors is provided with a series of flat surfaces 12 arranged on differing planes or angles to pron'de a series of facets, each of which acts individually as a reflecting surface.

Certain of the reflectors are. adapted to reflect a colored light, preferably red such as is employed in connection with railways, and for this purpose two' of the diametri 'ca-lly opposed housin shave positioned therein the transparent the like which are held within the housing by ineans of the clamping rings 15 adapted to be sprung within the housing. It has also been found desirable inpractice to employ the said transparent disks 14 positioned in advance of the reflectors 11. It will also be understood that these transparent disks 14 serve to close the housing at opposite sides of the reflectors whereby such reflectors are isks 14 of red glass or protected against the action of the elements.

The stands are arranged so as to bring the reflector within the 'rangefof the headlight of a locomotive and when a switch is thrown into open position, the housings pro- I vided with the red transparent disks serve to return the rays from the headlight so that the proper signal is given to the engineman.

We claim I A signal of the character described comprising an arm, a vertically disposed disk secured to said arm and extending above and below the arm, a housing surrounding the disk and comprising two substantially semi-circular sections, the inner end portions of the sections being secured to the outer end portion of the arm, a clamping member coacting with the opposite end portions of the c our signatures in the presence of two witnesscs. g v v WILLIAM H. ASHWORTH.
