TRAVELlNG HOIST..

Patented May 15, 1906..

Application filed September Z1, 1905. Serial No. 279,553.

of the King of Great Britain and Ireland, and

a resident of the borough. of Manhattan, in

the city, county, and State of New York, have invented certain new and useful Improvements in Traveling Hoists, of which the ollowing is a specification.

The main object of my invention is to construct a convenient form of traveling hoist or lifting-trolley which is adapted to be used where there is a limited amount of head room. For example, in the construction of tunnels, especially such as are built up with a lining of iron or steel segments, it is desirable to have a hoisting device to handle the segments and other parts to be used in the construction; but owing` to the limited amount of head room hoisting means of ordinary construction are not applicable. I meet the diiliculty by providing a hydraulic or other fluid-operated cylinder and mount it horizontally in a horizontally-traveling carriage, and with the cylinder and its piston I combine hoisting chains or wires, with the free hoisting end passing over wheels on the carriage.

In the accompanyingdrawings, Figure l is a side view showing how my improved hoist is applied in tunnel-constructing apparatus. Fig. 2 is a longitudinal section through the hoist, drawn to a larger scale. Fig. 3 is a sectional plan view of the same, and Fig. 4 is a transverse section.

Referring to Fig. l, A indicates a traveling stage within a segment-lined tunnel, and on the stage is to be mounted the hydraulic or other erector to put into place the segments with which the tunnel is lined. This erector is not shown; but the segments have to be lifted from the cars K and then carried for ward to the end of the stage to a position where they can be attached to the end of one of the erector-bars.

My traveling hoist, which is illustrated in outline at B in Fig. 1 and which I will now describe in detail in connection with Figs. 2, 3, and 4, is particularly adapted for this work.

The carriage of the hoist consists of a pair ol channel-beams D D, mounted upon wheels E, guided and adapted to travel on horizontal ways consisting of channel-beams F F, which may be mounted in or form part oi the raveling stage and under the main plat- '01111.I

` Between the beams D D of the carriage I mount the horizontal cylinder G, as by means of rings g g, bolted to the said beams. Within this cylinder works the piston H, eX- tending out throughastulling-box h and provided with a cross-head J, extending through and guided in slots K in vthe channel-beams D D of the carriage. To the outer ends of this cross-head J are attached the ends of hoisting chains or ropes M M, which pass to the opposite end of the carriage and there pass over pulleys P P, mounted to turn on a spindle N on the carriage.

To the free ends of the hoisting chains or ropes which thus hang pendent in a vertical plane the segments or other load can be attached, and then by introducing the hydraulic or other fluid-pressure through the inlet a: the piston will be forced outward, and the chains or ropes will thereupon raise the load to the desired height. Thereupon the whole carriage, with its load, can be traversed along the guideways F F like a trolley to deliver the load to the desired point.

I claim as my inventionl. The herein described traveling hoist, comprising a traveling stage, horizontal ways under the stage, a carriage adapted to travel on said ways, and a fluid-pressure cylinder and piston rigidly mounted on the carriage, in combination with a cross-head on the piston, guides therefor in the sides of said carriage, a pair of chains or ropes secured to the ends oi the cross-head, and pulleys on the carriage Iover which the ropes or chains may pass and hang pendent to receive the load.

2. The herein described traveling hoist, comprising horizontal ways, a carriage there on and a hydraulic iluid-pressure cylinder and piston mounted on the carriage, in combination with a cross-head on the piston guided in the carriage, a pair of chains or ropes attached to the cross-head and a pair ol pulleys mounted on the carriage near the opposite end :from that in which the crosshead is guided.

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

HENRY JAIP.
