TRANSFER-TABLE FOOR CARS.

SPECIFICATION forming part of Letters Patent No. 263,225, dated August 22, 1882,

Application filed March 16,1882. (No model.)

To all whom it may concern Be it known that I, NORMAN W. ROBINSON, of Pullman, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Transfer-Tables for Cars, of which the following description will enable others to understand and operate the same, reference being had to the accompanying-drawings, and to letters of reference marked thereon, forming a part of this specification.

This invention relates to an improved system for operating transfer-tables used in connection with car-shops or depot-buildin gs where cars are sheltered when not required for immediate service; and it consists in the employment, in combination with a transfer-table, of a dummy-engine for operating the said transfertable, as hereinafter set forth and claimed, whereby the cars are quickly and conveniently moved into or out of the building or shifted to the different tracks, as may be required.

Figure 1 isa top view embodying my improvement, showing the transfer-table and operating mechanism with a series of tracks leadingofi at both sides, the upper part of the carstructure, inclosing the dummy-engine, being cutaway in a horizontal plane. Fig. 2is an elevation embodying my improvement, showing the relation of the cars, dummy-engine, and depot-buildings Fig.3isadetached detail,partially in section, of the series of gear-wheels and intermediate shafts relative to the main or engine shaft and the axle of the dummy-englue ear. Fig. 4 shows the position of the gearshifting lever when the mechanism connecting the transfer-table and dummy-engine is out of engagement, and the dotted lines in Fig. 3 show the position of the same when in gear. Fig. 5 is a side elevation of the drag-rope, guide-sheaves, and supporting-bracket. Fig. 6 is a top view of the same, and Fig. 7 is a detached view of the friction clutch-pulley feathered onto the car-truck axle of the dummy-englne.

Referring to the drawings, A represents the platform of the transfer-table proper; A, the dummy-engine; A the carinclosing the same;

A a series of tracks communicating with the shops or depot-buildings, and A the transfer table and dummy-engine tracks running at right angles to the tracks A.

As shown in the drawings, three sets of tracks are used for the tran sfer-table, the dummy-engine being placed in the middle track. The mechanism of the dummy-engine is so arranged that the power may be applied to run cars onto and off the transfer-table, while the car carrying the engine remains stationary; or, by the shifting of a lever, as will be explained further along, connection is made with the axle of the dummy-car and the position of the engine and transfer-table changed as circumstances may require. 7

On the shafts or axles B B of the transfertable proper are placed the series of car-wheels B upon which the transfer-table moves.

Upon the shaft B are placed a number of gear-wheels, B which are adapted to engage with the series of pinions B on the shaft 0. This shaft G is also provided with the bevelgear wheels 0, adapted to engage with the bevel-gear wheel 0 on the shaft 0 having on the opposite end the bevel-gear wheel 0 engaging with the corresponding wheel, 1), located on the intermediate shaft, a. By this arrangement power and motion are transmitted from the engine to the transfer-table, and the mechanism is thrown in and out of gear by means of the lever a. The drum 0 consists of the outer shell and the inner sleeve, D, inclosing the shaft D as shown in Fig. 3 of the drawings, and is made to rotate therewith by means of the clutch D forming a part of the drum G engaging with the annular shoulder D on the gear-wheeled, which in turn engages with the pinion a located on the crank or en gine shaft E, carrying the pinion a, which engages with the gear-wheel E. The drum 0 receives the coil of the drag-rope b, and is thrown in and out of gear by means of the lever 1), connected with the projecting end of the sleeve D through the medium of the screw b as shown in Fig. 3 of the drawings,

The lever (1 (shown in Fig. 1 and broken away in Fig. 3) serves to throw the engine mechanism in and out of gear with the front axle of the dummy-car, this lever being at-' tached to the sleeve b feathered onto the axleshaft 12 Secured to the sleeve b is the clutch-wheel d, carrying the Wooden friction-quadrants 0?, as more clearly shown in Fig. 7 of the drawin gs, thebearin g-surfaces of which are cut away at an oblique angle, and when thrown in gear engage with the inner corresponding surface of the annular projecting rim d formed integral with the gear wheel d, which engages with the pinion d on the intermediate shaft, 01 which in turn engages with the pinion (Z on the shaft (1, by which motion is transmitted from the main or crank shaft of the engine to the dummy-car wheels. The quadrants d as they become worn are set out by the screw bolts (Shown in Fig. 7 of the drawings.)

One end of the drag-rope b is attached to the drum G from thence passing through between the sheaves E E journaled in the bracket Er, then through the snatch-block I and having on the outer end the hook F, adapted to engage with the body to be moved, the snatch-block, through which the drag-rope is rove, being secured at any convenient point and shifted as may be necessary. By means of the double sheaves the drag-ropemay be run off to either side of the dummy-engine to move the ears.

Fig. 2 shows the relation of the dummy-engine, cars, and buildings.

This shifting or moving cars from one department or building to another in the course of construction or onto the switch-tracks connecting with the main lines is now usually done by man-power, being both slow and expensive, while by my arrangement the cars can be handled with the greatest possible facility and the item of expense reduced to the lowest minimum.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. In a transfer system, as described, the combination, with the transfer-table A and the shaft B, of the series of gear-wheels B the with counter-shaft 0, bearing pinions 13 B,

severally in engagement with said gear-wheels B and dummy-engine mounted upon an independent carriage, but by means of shaft 0 in connection with said counter-shaft 0, whereby power is uniformly transmitted to each of said bearing-wheels independently.

5. A traveling transfer-table permanently connected to and operated by a dummy-engine mounted upon a separate carriage, combined with a drag-rope and winding-drum operated by said engine independently of the traction-wheels, and suitable guide-pulleys, whereby the cars may be drawn onto or off the transfer-table, as set forth.

4. The combination, with a dummy-engine and traveling transfer-table actuated thereby, of the drum 0 provided with the clutch-box D the drag-rope b, the sheaves E 15 and the bracket 15, substantially as herein shown and described.

5. The combination, with the engine car-axle b of the sleeve b the clutch-wheel d, the adjustable quadrant-blocks (Z and the gearwheel 01 provided with the annular rim 61 substantially as and for the purpose described.

NORMAN W. ROBINSON.
