PAUL GENESY, 0F OGDEN, UTAH, ASSIGNOR, BY DIRECT MESNE ASSIGNEEHTS, T0 GENESY ELECTRIC LANTERN COMPANY, A. CORPORATION 015 WYOMING.

, ei en;

in the county of Weberand State of Utah,

have invented certain new and useful Improvements in Railroad Lanterns, of whloh the following is a specification, reference being had to the accompanying drawings.

This invention relates to lanterns, and particularly to lanterns of the type used by conductors, brakemen and trainmen generally on railways, and the general object. of the invention is to provide a lantern which will stand a lot of hard usage, which is designed to be illuminated by an electric light energized the ordinary dry battery, and which is extremely simple.

A further object is to provide a lantern of this character so constructed that the light is thrown downward when the body of the lantern is not lifted to a horizontal position.

And a further object is to provide'a construction of this character wherein a very simple form of switch is provided to connect or disconnect the battery with the lamp.

Another object is to provide for the use of a light condensing lens opera-tin in conjunction with the refiector and t e lamp, which lens is adjustable to alter its focus. j

Other objects have to do with the details of construction and arrangement of parts as will appear in the course of the following description. g

My invention is illustrated in the accompanying drawings, wherein igure 1 is a side elevation partly in section of one form of my improved lantern;

Referring to these drawings and particularly to Figures 1 to 4, 1O designates the body of the lantern, which is made in the form of a cylindrical battery receiving receptacle closed by a hinged lid 11 at its upper end. Riveted or otherwise attached to the body 10 at opposite points are the handle sockets 12, and engaged in said handle sockets is a handle 13 which is preferably of wood and arches over the top of the lamp.

The lower end of the body 10 is permanently closed by'a head 14, the central portion of this head being concave, as at 15, to provide a reflector, and at the central portion of this reflector there is provided a lamp socket 16 designed to receive within it the base 17 of the lamp 18. Attached to the lower end of the body in any suitable man-,

ner are a plurality of outwardly and down- .the bottom of the lamp body10 are rods 23,

illustrated as two 'in number, though-more may be used, which pass through the ring 22 and with which said ring 22 has sliding engagement. The ring 22 is frictionally held in engagement with these rods by means of a semi-circular 5 ring 24 disposed within a; groove 25 forme in the ring, this spring bemg attached at its middle to the-ring, as by soldering. The l'pwer ends of the rods 23 are angularly bent orfotherwise formed to provide heads 26 to liinit the outward movement of the lens.

Mounted within the body is a metallic disk 27 formed with downwardly projecting legs 28, these legs being angularly bent to provide screw-threaded feet 29 which bear against the inner face of the bottom 1% and are attached thereto by screws. Thiscmember 27 is formed to provide the screw-thread- AUSTIN W. GRAHAM, OF CARROLLTO N, ILLINOIS.

' TRACTION WHEEL.

Specification of Letters Patent.

Patented Mar. 28, 1922.

Application filed April 13, 1921. Serial No. 460,909.

To all whom it may concern:

Be it known that I, AUSTIN l/V. GRAHAM, a citizen of the United States, residing at Carrollton, in the county of Greene and Stateof Illinois, have invented certain new and useful Improvements in Traction WVheels, of which the following is a specification, referencebeing had to the accompanying drawings.

This invention relates to traction wheels, and has for its object to provide a wheel having a broad ground engaging surface capable of properly supporting a vehicle regardless of the weight of the vehicle;

Another object is to provide a wheel of this character including a plurality'of traction lugs which are disposed flush with the outer edges of the wheel to eliminate jarring of the vehicle when traveling over hard surfaces.

Another object of the invention is to provide a wheel of this character including a plurality of traction lugs disposed inwardly of the periphery of the wheel and having their ground engaging edges disposed flush with the outer edges of the wheel whereby said lugs may engage the ground to permit the wheel to obtain a firm grip, without plowing or packing the ground in addition to properly supporting the wheel when traveling over soft ground.

A still further object of the invention is to provide a Wheel of this character including a pair of beveled rims connected by a plurality of traction lugs arranged to permit the wheel to obtain a firm hold when traveling through mud and sand.

Another object is to provide a wheel of this character including a pair of beveled rims, the beveled portions of each rim extending in opposite directions and'toward each other, one of said rims being broader than the adjacent rim to provide a mud guard for the operating parts of the vehicle disposed adjacent the wheel.

Vith these and other objects in view the invention consists in the improved construction and arrangement of parts to be hereinafter more particularly described, fully claimed and illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of a traction wheel constructed in accordance with an embodiment of the invention.

Figure 2 is a top plan View.

Figure 3 is a detail view of the traction lug.

Figure t is a section taken on the line et-4 of Figure 1.

Referring to the drawings, 5 designates a tract-ion wheel comprising rims 6 and 7, each rim havingv its outer and inner surfaces inclined or beveled.

The outer edges of the rims are disposed in parallel planes. The beveled peripheries of said rims are inclined toward each other so as to substantially form a channel 8 through the cooperation of the beveled peripheries. The rim 6 is relatively wide and is adapted to be disposed adjacent the vehicle so that soil picked up by the wheel in the course of travel is prevented by the broad rim from coming in contact with the gears or like operating parts carried by the vehicle, the beveled surface of the rim in this instance serving to deflect the soil from said parts. 7

The rims 6 and 7 are not disposed in spaced relation in order to provide a relatively broad wheel but in order to render the wheel light in weight as well as broad in traction surface, there being provided novel means for connecting the rims comprising a plurality of traction lugs 9. Each lug, has its end portions extended at right angles to the lug on an oblique line, to provide feet i and 11, the foot 10 extending in the opposite direction to the foot 11. The traction lugs 9 are disposed transversely of the rims 6 and 7, the foot 10 of each lug being secured to the rim 6 while the foot 11 is secured to the rim 7 by any suitable means. By extending the feet on an oblique line, the lugs are made to conform to the channel formed through the cooperation of the beveled peripheries of the rims so that the ground engaging edge 12 of each lug is disposed flush with the outer edges of the rims 6 and 7. In this way, the outer edge of each rim is permitted to engage the ground even when the wheel is traveling over pavements and like hard surfaces and in view of this, jarring of the vehicle is eliminated as a relatively smooth periphery is provided. In addition to this any soil picked up by the traction lugs may pass between said lugs and be discharged onto the ground as the intermediate portion of the wheel is open.

From the foregoing it will be readily seen that this invention provides a novel form of lishing said connection.

5. A railway lantern of the character described comprising a body constituting a battery containing case, a skeleton guard extending from one end of the case and adapted to support the same, a plurality of differently colored electric lamps disposed in this end of the case, a switch whereby any one of said lamps may be electrically con- 10 nected' to the battery or. disconnected therefrom, and inde endent concave reflectors disposed behind and concentric to each lamp.

In testimony whereof I hereunto aflix my 15 signature.
