ELECTRIC LOCQMOTIVE FOR ELEVATEDTRACKS.
SPECIFICATION forming part of Letters Patent No. 511,862, dated January 2, 1894.
Application filed October 29, 1891. Serial'll'o. 410,244. (No model.)
To all whom it may concern:
Be it known that I, CHARLES H. ROBERTS, a citizen ofthe United States, residing at Hartwell, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Electric Railways; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany ing drawings, and to the figures of reference marked thereon, which form a part of this specification.
My invention has relation to electric railways for logging purposes, and the improve- ,ments relate more particularly to the loggingcarriage, as will be hereinafter fully described and pointed out in the claims.
In the drawings, Figure I is a side elevation of a portion of a track having suspended therefrom, and in engagement therewith, a transporting carriage. Fig. II is an end elevation on an enlarged scale of the same, showing the girder and track-rails in cross-section. Fig. III is a transverse sectional detail view through one set of the sprocketwheels, one of the suspension-wheels, a portion of the supporting-rod or hanger being shown in full lines.
Referring by reference numerals to the accompanying drawings, 1 designates one of the transverse supporting cross-beams or girders of the trestlework from which the rollingstock is suspended and supported, and 2 is a girder suspended from the cross-beams, 1, in any suitable or desired way but preferably by depending rods or hangers, 6, in any of the well-known ways, as shown in Fig. I, where the said hangers, 6, are illustrated as secured by shoulders or enlargements at their lower ends and by nuts, 41, at their upper ends, Upon the girder, 2, the two upper track- rails 3, 4 are secured in any of the well-known ways, and to this girder is also secured in the usual manner the lower or guiding rail 5. Each of these rails is of the ordinary T-rail form. The suspending-rods 6 are sectional rods formed of sections 7 and 8, they being connected at their meeting points by tightening-nuts 9. The hanger-rods 6 are threaded at their upper ends and pass upwardly through the longitudinal beams of the trucks 10, the projecting upper ends of said hanger-rods being threaded, encircled by spiral or coiled springs 11, and passed through tie-rods 12, and afterward secured in place by threaded nuts 13. Brace- rods 14 and 15 are bolted at their extremities to the upper and lower truck-frames to give additional strength to the transporting carriage. Electric impelling wires 27, 28
are suspended beneath the truck beam and the spring-controlled trolley 25 engages either one of these wires, according to the direction in which it is desired to have the carriage move along the elevated track. The dynamo may be of any ordinary pattern that can be conveniently used and is preferably located beneath the car-trpck and within convenient proximity to the drivers cab. A spring-actuated trolley 25 connects or contacts with the lower or guard-rail 5. The electric propelling wires 27, 28, are supported in any of the usual ways beneath the suspended beam of the structure, and preferably intermediate of the front and rear wheels of the carriage, when fore and aft wheels are used, which, however, is not an essential feature of the invention. The trucks are provided each with three sprocket- wheels 29, 30 and 31 over which the chains 31 which engage with the sprocketwheels 32, 33, on the lower traveling or car wheels 34, 35, run. The sprocket-wheels 30 and 31 are of course keyed to the shafts or axles of the upper traveling or truck-wheels, 42, and 43. chain 36 engages the sprocket of the drivingwheels, and passes once around the drivewheel 37 of the dynamo-machine. Adrivers car40 is suspended at the rear of the carriage. hen it is desired to carry logs from the felling-forests to the market or shipping point the front Wheel is dispensed with and the frame alone is employed from which to suspend the log, so that the latter may be carried to theshipping point.
The drivers car is suspended by rods from the carriage in any convenient and practical manner. This road is designed to be projected into a forest where timber is to be or has been felled for the purpose of transportation of the same to a shipping-point, and in a country where railroads are not financially practicable or easy of construction.
(See Fig. III.) A belt or endless Although I prefer to use a dynamo to propel the traveling wheels of the truck by the sprocket-wheels and chains as described, yet it is manifest that any other suitable motor may be employed and connected by any suitable means with the traveling wheels to impart rotation thereto.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
1. The combination With an elevated track beam supported by hanger-rods and trestlework, and electric imp'elling-wires arranged beneath the trackbeam, of upper trucks mounted upon the upper track-rails and provided with sprocket wheels and the lower flanged-wheel mounted on a shaft provided with sprocket-wheels,chains connecting the 7 upperand lower sprocket-wheels,an actuating dynamo-machine connected therewith, and a spring controlled trolley connected to the dynamo-case and engaging the lower track-rail of the structure, substantially as specified.
2. The combination with the supported track-beam provided with two upper trackrails and one lower track-rail, of the springactuated trucks mounted on said upper trackrails and having tension sprocket-wheels connected by sprocket-chains, of the lower larger sprocket wheels connected by an endless chain in engagement with a dynamo machine supported in the carrying frame, substantially as specified.
3. The combination with the suspended track of the flanged traveling wheels the connected sprocket-wheels, the sprocket chains,
and the depending hanger rods, the lower sprocket-wheels, and the flanged-wheel engaging the lower track-rail, substantially as specified;
4E. The combination with the track-beam provided with upperand lower track rails, of a suspended truck having upper and lower flanged wheels, sprocket-wheels on the shafts of said upper and lower flanged wheels, chains connecting the relative sprocket wheels, and
a suspended drivers car supported from the main carriage, substantially as specified.
5. The combination, with an elevated trackbeam provided with upper and lower trackrails, of upper trucks whose wheels engagethe upper track-rails, and a lower truck having wheels engaging the lower track-rails,
hanger rods attached at their lower ends to the lower truck and passing up through the upper trucks, and springs interposed between t the upper trucks and the upper ends of the hanger-rods, substantially as set forth.
'6. The combination, of a suspended trackbeam provided with upper and lower trackrails, with upper trucks whose wheels engage the upper track-rails, and lower trucks suspended from the upper trucks by longitudinally, yielding hanger-rods, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
