*HOSE-smoes.

SPECIFICATION forming part of Letters Patent No. 595,645, dated December 14, 1897.

Serial No. 626,754. (No model.)

' burg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Hose-Bridges and I do declare the following to be a full, clear, and

A 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 accompanying drawings, and to the figures and letters of reference marked thereon, which form a part of this specification.

This invention relates to a certain new and useful improvement in hose-bridges, in which- Figure lis a longitudinal section of bridge at C D of Fig. 2, showing one side. Fig. 2 is a plan. Fig. 3 is a transverse section at AB of Figs. 1 and 2. Fig. 4 is a large view showing the end of the arched frames as joined at rails, the said frames being tangent to the rail at F and E and S of the arc.

1 and 2 are frames conforming to an arc of a circle, the ends being a1: an angle to the rails and made of cast iron or steel or any other suitable material.

3, 4, and 5 are doubleTheaded tie-rods for tying the frames together.

6, 7, and 8 are spreaders.

9 are the slotted dogs for gripping the paving-stones and preventing the frames going forward.

10, 11, and 12 are ratchet holes or openings in the said frames through which the hose may pass.

13, 14, and 15 are horizontal and vertical slots for securing the tie-rods 3, 4, and 5.

16, 17, and 18 are projecting lugs on the frames 1 and 2 for fastening the spreaders 6, 7, and 8.

19, 20, 21, and 22 are projecting lugs on frames l and 2, to which the lugs 9 are pivoted.

23, 24, 25, and 26 are bolts on which the dogs are pivoted.

27, 28, and 29 are recesses in the projecting lugs 16, 17, and 18, in which the ends of the spreaders 6, 7, and 8 are inserted.

30, 31, and 32 are nuts for adjusting the spreaders 6, 7, and 8. 33, 34, and 35 are collars on the said spreaders.

36 and 37 are grooves in the bottom of frames 1 and 2 to fit over the heads 38 and 39 of the rails 40 and 41. 42, 43, and 44 are the wedges having a rough surface on one side and smooth on the other for wedging between the said rails and grooves by Way of the arched openings, the rough surface coming in contact with the heads of the rails.

The object of my invention is to provide means of bridging over the hose that may be laid over the street-railway track in the time of any conagration or lire, so the cars may not be delayed, by having the frames 1 and 2 tted to the said tracks by placing the grooves 36 and 37 of the said frames over the heads 38 and 39 of the railway-tracks 40 and 41. The frames 1 and 2 are then tied together by the double-headed tie-bolts 3, 4, and 5, which are inserted in the horizontal and verr tical slots 13, 14, and 15. The ends of the spreaders 6, 7, and 8 are then inserted in the recesses 27, 28, and 29 of the lugs 16, 17, and 18 and adjusted by the ynuts 30, 31, and 32. The slotted dogs 9 are bolted to the lugs 19, 20, 21, and 22 with their points downward and in contact with the paving-stones. When the car comes in contact with the bridge, the dogs 19, 20, 21, and 22 hold the same from moving forward. The hose passes'through the arched openings 10, 11, and 12. It will be thus seen that by bridging over the hose in this manner the great loss, trouble, and inconvenience caused to the railway company in case of a re will be avoided.

Having described my invention, what I claim as new, and wish to secure by Letters Patent, is as follows:

1. Ahose-bridge comprising the'arc-shaped frames, having flanged bottoms adapted to t over the rails of a railwaytrack, the tops of said frames being of the same shape as a railwaytrack, openings in each frame for the reception of the hose, dogs attached to each of said frames adapted to engage with the pavement, adjusting-rods attached to each frame, and rods for securing said frames together, substantially as shown and described.

2. A hosebridge constructed of frames of iron or steel or any suitable material, the

IOO

said frames being the are of a circle, the said arc being at an angle to the rail, the chord of which has a groove and flange to fit over the heads of the street-rails, the ange between the are andthe chord of the said circle, having thereon series of arched openings by which the hose is arched over, of the vertical and horizontal slots in the walls of the arched openings for which the double-T-headed tierods are fastened, of the slotted dogs by which the said bridge is held from any forward movement when the car strikes the said bridge of the wedge having one smooth and one rough surface for wedging between the groove in the are and head of the rail-frame as described and substantially set forth.

3. A hose-bridge constructed of frames of iron or steel or any suitable material, the said frames being the arc of a circle, the said arc being at an angle to the rail, the chord of which has a groove and flange to fit over the heads of the street-rails, the iange between the arc and the chord of the said circle, having therein series of arched openings by which the hose is arched over, of the vertical and horizontal slots in the walls of the arched openings for which the double-T-headed tierods are fastened, of the slotted dogs by which the said bridge is held from any forward movement when the car strikes the said bridge of the wedge having one smooth and one rough surface for wedging between the groove in the arched frame and head of the rail, in combination with the double-headed tie-rods7 of the spreaders having adjusting nuts and collar and rod bent as shown, of thc lugs projecting from the arched frames for fastening the slotted dogs by means of bolts of the lugs projecting from the arched frames having square and round recesses therein for 4o thc ends of the sprcaders, as described and substantially set forth.

In testimony whereof I affix in presence of two witnesses.

JAMES F. MORRISON.
