HOSE-BRIDGE.

SPECIFICATION forming part of Letters Patent No. 651,452, dated June 12, 1900. Application filed December 15, 1899. Serial No. 740,400. (No model.)

To all whom it may concern: A

Be it known that I, MICHAEL UJAK, a citizen of Hungary, residing at No. 143 Washington avenue, Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Hose-Bridges; and I dohereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to an improved hosebridge for railway-tracks; and it consists in the certain details of construction and combination of parts, as will be fully described hereinafter.

In the accompanying drawings, Figure 1 is a plan view of my improved hose-bridge for railway-tracks,which is constructed and arranged in accordance with my invention. Fig. 2 is an end sectional elevation of the same. Fig. 3 is a side elevation of the device.

To construct a hose-bridge inaccordance with my invention, and thereby provide a means whereby street and other railway cars may be transferred over several lines of firehose, I provide two sections of rails l, each of which is formed with openings 16, through which the lines of hose 17 pass, and also with wedge-shaped or inclined ends 2. These rails 1 are coupled together by means of transverse bolts 3, and each is formed with a series of inwardly-projecting bearings 4, adapted to rest upon the flanges of the street-rails 9. Attached to each of these rails 1 by means of bolts 20 are a number of hooks 18 and 19, the one set 19 adapted to fasten to the pavement on the inside of the track and the other set, 18, to the pavement on the outside of the same. Formed through eachof the lugs or bearings 4 are transverse openings 5, used for the reception of the points of devices for rigidly attaching the rails 1 to the car-track 9. Two of these above-mentioned devices are used, and each consists of two bars 6, having forked ends 7, adapted to engage the lugs 4 and flange 8 of the street-rail, and each pivotally connected by suitable bolts 10 to bars 2l, arranged at either side of the said forked bars 6. Attached to one end of these parallel bars 21 is a clip 11, forming a bearing for a hinged lever 12, and at the opposite end of the said bars 21 is arranged a lock 13 and locking-pin 14.

In operation the rails 1 are laid upon the car-track 9, arranging the hose in the openings 16 and driving the hooks 18 and 19 into the pavement. By means of a suitable tool a small cavity7 is formed in the pavement beneath the flange 8 of the street-rail and the outside lugs 4. The lever 12 of the attaching device is thrown to a position such as shown in dotted lines on the drawings, and the forks 7 for the bars 6 engage with the lugs and flanges of the track-rails in the manner shown at Fig. 2 of the drawings,and the lever is forced down and locked by the pin 14. This downward movementof the lever will tend to separate the forks 7, thereby wedging the rails to the track, at which time cars may safely ride over the hose.

It is obvious that slight modifications and changes may be made in the general details without departing from the spirit of the invention.

Having thus described my invention, I claim- The herein-described hose-bridge, consisting of the sectional rails 1, constructed as described, and provided with tapering ends 2, and openings 16 for the hose,the pivoted hooks 18 and 19, attached to the said rails, the bearings 4 formed with the rails and adapted to reston the flanges of the street-rails,the openings 5 through the said bearings for engagement with the forks of ,the locking device, the said locking .device consisting of the bars 6 pivoted to a frame 2l, and each provided with forked ends 7, the pivoted lever 12 attached to the said frame, and a lock 13 for the same, all arranged and combined for service, substantially as, and for the purpose'described.

In testimony whereof I have hereunto afxed my signaturein the presence of two subscribing witnesses.

MICHAEL UJAK. Witnesses:
