HO'SE-BRIDGE.

bSPECIPICATION forming part ofl'retters Patent No. 352.038, ated November 2, 1886. Application filcd January 16, 1886. Serial No. 188,:754. (No model.)

To aZZ whom it may concern:

Be it known that I, DAVID F. OARROLL, a' citizen of the United States, residing at Brooklyn, in the county of Kings' and State of New York, have invented a contrivance to facilitate railroad-travel, tobe called the Car rollon, of which the following'is a spccification.

Hitherto in cities, when a building takes fire and the fire-engines reach the spot, it very often happens that the fire-hose is stretched across railroad-tracks, thus necessitating the stoppage of traffic on the road. My invention is intended to obviate the necessity of said stoppage. i v

lt consists of a portable structure made of i ron, steel, or other suitable material. (Marked Figure .1 in accornpanying drawings.) It is the samewidth as a car-track, and is so constructed that'it comes to a point at each end, Where it ineets the railroad-track. From there it rises gradually toward the center until it has reached a height of several inches.` Through it there are several openings, (marked O O C in Fig. 1,) through which the fire-hose can be stretched. The railroad-car can thus pass over the hose on this Structure, using one on each track. To secure this to track, there are'two pairs of lugs projecting downward, one pair near each end. (SeeB B, Fig. 1.) These are int'ended to catch track and keep Structure in place.

To prevent from overturning while a car is passing over it, there are two fianges on each side, extending several inches out- Ward on a vlevel with the bottom. (See D D, Fig. 1.) These are intended -to rest on the pavement. Through the fianges is a hole by which it can be fastened to the groun'd, if necessary. the pavement the fianges do not rest thereon, a few iron washers will remedy the defect.

It very often happens that the stone pavement of a street is above the level of the railroadtrack. This would raise the fianges and keep the'strncture off railroad-track. To remedy this, I have so constructed this thatboth ends work ou the hinge principle, (see A A, Fig. 1,) thus allowing ends to rest on track under all circumstances.

Fig, 2 represents the invention in a different position from that of Fig. 1. 'Fig. 3 represents cross view of fianges D D in Fig: 1. Fig. 4 represents cross view of lugs B Bin Fig. 1, Fig. 4 being the groove between lugs into which railroad-track fits. p

I claini as my invention- The hose-bridge, Fig. 1, having lugs B B, flanges D D, and ends A A, connected to main Structure by hinges, as set forth.
