RAlLWAY-TRACK LAYER.

SPECIFICATION forming part of Letters Patent No. 775,926, dated November 29, 1904.

Application filed April 2, 1904. Serial No. 201,203- (No model.)

To all 1.0720172, 77/ may concern:

Be it known that I, EDWARD Srnnonn JOHN- soN, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented new and useful Improvements in Rail- Way-Track Layers, of which the following is a specification.

This invention relates to devices for laying track used in connection with a steam-shovel or excavator, particularly to the railway-track layer shown in Patent No. 744,870 to W. B. Michel.

The object of my invention is to improve the construction shown in said patent by i1nproved devices for hoisting and conveying a railway-track from one end of the shovel to the other. This is effected by means of a small hoisting-engine carried on the car, connected by appropriate tackle to the traveler, which carries the track-section.

In the accompanying drawings, Figure 1 is a plan View showing the improvements. Figs. 2 and 3 are details in side and end elevation of the traveler.

Referring specifically to the drawings, the car of the excavator or shovel is indicated at 1, the shovel-boom at 2, the rear boom at 4, the track at 5, said track being supported by rods depending from the boom, as more fully shown in the patent above referred to. Braces for supporting the track are indicated at 6.,

The railway-track section to be moved is indicated at 18, and chains connected thereto are indicated at 17.

The new parts invented by me will now be specified. At 7 a small hoisting-engine is indicated of any desired or suitable construction, and this engine by suitable gearing rotates drums 8, which are carried at the ends of shafts 9,which conveniently project through the side of the car, so that the drums are on the outside thereof. The forward drum is connected to a cable 10, which extends thence around a sheave 11 at the front corner of the car, another sheave 12 at the front end of the track 5, and a third sheave 13 at the bend of said track, and thence around the hoistingpulleys 14 and 15 on the traveler 16, the lower pulley 15 being in position to hook into the chains 17. A hoisting and conveying tackle is thus formed. Another cable 20 runs from the rear drum 8 around sheaves 21, 22, and 23 to rear connection with the traveler 16. The traveler can. thus be pulled in either direction.

In operation the track-section is hoisted by means of the engine and cable 10, and then both drums are thrown in gear and convey the track-section in the direction desired.

The details of the track and traveler thereon are shown in Figs. 2 and 3. The track is preferably an l-beam, on the lower flanges of which the oppqsite wheels 16 of the traveler roll, and the braces 6 are bolted to the top flanges of the beam, as shown.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination with the car, and track supported beside the same, of a hoisting-engine on the car, sheaves at front and rear end of the track, a traveling hanger on the track, and a hoisting and conveying cable connected to the engine and the hanger and extending around the sheaves.

2. The combination with the car, and track supported beside the same, of a hoisting-engine on the car having a pair of winding-drums, sheaves at each end of the track, a traveling hanger on the track, carrying a hoistingtackle, and cables connected respectively to the drums and extending around the sheaves to the hanger, one of the cables forming a part of the hoisting-tackle.

3. The combination with the car, of the I- beam track extending along beside the same, the braces projecting from the car and secured to the top of the beam, and the traveling hanger having wheels rolling on the bottom flanges of the beam.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWARI) SPENCER JOHNSON.
