To all whom it may concern.-

Be it known that I, JOSEPH F. HADDOGK, a citizen of the United States, residing in the city of St. Louis and State of lVIi'ssouri, have invented new and useful Improvements in Railway-Markers, of which the following is a specification.

This invention relates to railway lanterns of the type commonly denominated markers, and has for its general object to provide means whereby an ordinary oil lantern of this description may be electrically lighted.

The character of lantern to which my invention relates is adapted to show two colors of light, red and green; and is provided with four bulls-eyes, three of which are of green glass, and one of red.

In practice a marker is placed on each corner at the rear end ofthe last car to extend beyond the sides thereof; and is normally set to show a green light to the engineer, a red light at the rear, and a green light at either side. Each marker is also rotatably mounted so that it maybe readily turned to display green lights at the front,

rear and side when the train moves on to a siding.

My invention embodies means for permitting the lantern to be turned in the usual way, for the purpose indicated above, with out breaking the electrical con-tact.-

My invention also embodies means whereby the lantern may be either automatically lighted by the act of mounting it'on the bracket of the car; or through the medium of a conductor leadingfrom a lamp socket, or other electrical station, on the car, and having contact members for establishing electrical connection with the electric lamps mounted in the lantern.

The invention also embodies various novel constructions and combinations of parts, all

of which will be clearlyset forth inthe detailed description of the following.

In the accompanying drawings, Figure 1 is a view, partly in section and partly in elevation, of a marker constructed according to my invention; Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig.1; Fig. 3 is a view in elevation of the lower portion of my improved marker and of a section of the corner post of a car,

illustrating the manner of mounting the marker on a bracket provided on said corner post to establish electrical connection with contact-members provided on said bracket; Fig. 4 is a horizontal sectional view taken substantially on the line 11 of Fig. 1, certain parts being broken'away to better illustrate the construction; Fig. 5 is a sectional view taken on the line 5-5 of Fig. 3; Fig. 6 is a cross sectional view taken on the line 6 6 of Fig. 4; and Fig. 7 is a view in elevation on areduced scale illustrating the marker mounted on a dead bracket, and in a detached view a conductor provided with contact-members for establishing electrical connection with the marker.

Referring now to these drawings, the numeral 8 indicates, generally, a marker which, except for my added improvements, is of the usual or any preferred construction, and comprises a casing 9 having mounted therein bulPs eye's- 1O, 11, 1-2 and 13, of which the bulls-e'ye 10 can be considered as being red. One of the bullseyes, say 13, is mounted on-a slidable section 1% which is movable to give access to' the interior of the casing. Within the casing there is provided a false bottom 15 adapted to support an oil lamp 16. The bottom 15' is provided, around its periphery, with a hollow annular ridge 17 which pro vides a recess in the bottom for receiving the lamp 16. Mounted on the ridge 17 opposite the bnlls eyes 10,- 11- and 12,; respectively, and communic'at ing with the annu-lar' space 18 provided by said ridge, are hollow posts 19, on the top of each of which is mounted an electric lamp 520. It will be understood, of course, that the top of the posts 19' are provided with sockets for removably receiving the lamps 20. The conductors 2l'leading'from such sockets are carried through the posts 19' and connected to two main conductors located in the recesses 18. The conductors 22 are held in position in the recesses 18 by an insulating plate 23 secured in the casing of the lantern under the false bottom 15. The conductors 22 are also insulated, and at a convenient point are extended through openings provided in the wall of the ridge 18 and the casing 9, as indicated in Fig. 6, and have their bared end portions connected to binding screws 23 mounted, respectively, in the ends of contact-rails 24 which partly encircle the bottom portion of the marker.

The rails 24 are mounted on a strip of insulating material 25 by means of screws, rivets or the like, 26, and a similar strip of insulating material 27 is interposed between the strip'25 and the casing 9, and said strips of insulating material are secured to the casing 9, as by means 01 screws 28. An insulating stop-block 29 (Fig. 4) mounted on the end of the strip 25 by means of screws 30 abuts against the binding screws 23, and a similar insulating stop-block 31 secured by screws 32 abuts against the opposite ends of the contact-rails 24. The bottom of the marker is grooved to provide a seat for a ring 33, which ring carries a bracket-arm 34 having a head 35.

The numeral 36 indicates a support mounted on the corner post 37 of the car, and provided with a locking-groove to receive the head 35 of the bracket-arm 34.

The parts just described are of the usual construction, and when the marker is mounted on the support 36 it may be freely turned in the ring 33.

In order to provide for automatically lighting the marker as it is placed in position on the support 36 I mount beneath the support 36 a bracket 38 on which is mounted an insulating plate 39.

The numeral 40 indicates contact-members having twin spring-tongues 41, said contactmembers being secured near opposite ends of the plate 39 by means of screws 42 passing upward through said plate and screwing into the bottom of said contact-members. One screw of each contact-member acts as a binding-post to which is connected a

conductor

43, 44, respectively, which in practice would pass through a small opening in the corner post and connect with the source of electricity carried by the train.

Mounted on opposite sides of the bracket arm 34 are two insulating-blocks 45, on each of which is mounted a plate 46 provided with an integral knife-edge contact-member 47 projecting at right angles to the plate 46 and to the insulating-block 45, each of the plates 46 having an integral portion at its top indicated by 48, which extends parallel with the top of the insulatingblock 45 and terminates in a spring contact-finger, one of said contact-fingers, indicated by 49, being bent upwardly to engage the under side of the upper contact-rail 24, and the other of said contact-fingers, indicated by 50, being bent downwardly to engage the top side of the lower contact-rail 24. The portions 48 of the plates 46 are connected and covered by a block of insulating material 51.

It will now be seen that when the marker, constructed as described, is lowered into position on the support 36 the contact-members 47 will enter between the twin tongues 41 to form electrical contact therewith, which thereby establishes connection through the contact-

fingers

49, 50, and rails 24 with the.

the source of electricity the construction illustrated in Fig. 7 will be employed. This arrangement differs from the construction previously described only in the fact, that no contact-members are provided in connection with. the support 36. In such case I employ an ordinary flexible conductor 52, the respective wires of which are electrically con.- nected with twin tongue contact-members 53 mounted on an insulating-block 54 carried by a bridge-piece 55, around which the conductor 52 may be wound, or to which it may be suitably connected in any preferred way to carry the contact device as a whole. The opposite end of the conductor 52 will carry a plug 56 of the usual description for insertion in a socket. When the marker is in position on the support 36 the contact-members 53 are inserted over the contact-members 47 from above, and thus establish the electrical connection with the lamps of the marker as will be understood.

Theoil lamp 16 is carried in the lantern so that if for any reason the source of electricity should fail, or the electrical contact should be broken, said oil lamp could be at once lighted, and thus the danger of the train traveling without its tail lights be avoided.

Many advantages incident to theuse of electric markers might be enumerated, but i as most of these will be apparent to those skilled in the art, such as those of greater security, by obviating the necessity of handling, or carrying oil, and of economy and cleanliness, I think it necessary in this connection to emphasize only the fact that the use of my electric marker will enable a much brighter and more penetrating light to be employed, which is of great advantage in the case of a heavy rain, snow or fog.
