Description
(Nd Modemc l H. 'SANDROGKI HOSE BRIDGE Patented May 1, 18194.
. f UNITED STATES PATENT EFICE.
HENRY SANDROOK, OF NEW YORK, N. Y.
HOSE-BRIDGE.
SPGIFICATION forming part of Letters Patent No. 519,136, dated May 1, 1894.
` Application filed October 24=`|1893 Serial No. 489,034.. (No model.)
To all whom it may concern.:
Beit known that I, HENRY SANDRocK, of New York city, New York, have invented an ImprovedHose-Bridge, of which the following is a specification.
This invention relatesto aliose bridge which is adapted to be placed upon a track and over a hose, so that a car may safely pass over the latter. The hose bridge is composed of three separate sections which may be interlock'ed, and which when disconnected may be "conveniently stored away under'the car seats.` In the accompanying drawings Figure l is a plan, partly in section, of my improved hose bridge. Fig. 2 is a cross section on line a; m, Fig. 1; Fig. 3 a longitudinal section on line y, y, Fig. 1;, and Fig. 4 a perspective View of one of the blocks a. y
My improved hose bridge is composed of three parts, viz: two arched blocks a, and a connecting tubular casing b. Each of the arched blocks a., is grooved at its base as at a', to t upon one of the rails A, of the track. The upper curved side or tread of the block is also grooved as at 0.2, to receive the iiange of the car wheel. A transverse perforation a3, adapted for the passage of the hose B, extends through the center of the block. To the right and left and over this perforation there is formed u'pon the inner faceof the block a, a grooved seat a4, adapted for the reception of the end of the transverse casing b. The groove a4, is open at the top (Fig. 4), while at its sides, it isseparated from the rails, so that the hose B passes through the i perforations a3. The casing b, is then projected over that portion of the hose which traverses the track between the rails. The ends of the casing will engage their seats a4,
of the blocks, and thus the entire structure is properly interlocked. When the car passes over the bridge, the block a, will protect the hose against the wheels, while the casing b, will protect it against the horses. y i
It will be seen that my improved hose bridge may be readily put down and removed, is effective in preventing injury to the hose, and
may be compactly stored away.
The combination of blocks 0L, having longi tudinal groove a', transverse perforation as, flanges a5, and an open groove a4, around such perforation with a tubular casing b, adapted to engage groove a4, substantially as specified.
