HOSE-BRIDGE.

SPECIFICATION forming part of Letters Patent No. 386,008, dated July 10, 1888.

Application filed December 24, 1887. Serial No. 258.872. (No model.)

To @ZZ whom it may concern.'

Beit known that I, CHARLES J. l. HEIM, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Hose-Bridges, of which the following is afull, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this speciiication.

This is a portable device for supporting firehose at an elevation, so4 as to carry it over a street-railway or other track.

Figure I is an isometric perspective view of the device. Fig. II isan axial section of a brace. Fig. III is a perspective View of the arch-strap, through which the hose passes. Fig. IV is a perspective view of the standardsockets. Fig. V is a detail top view of a connection between one end of the arch and the standard-sockets. Fig. VI is a perspective view of one of the standard cross-bar sockets. Fig. VII is a perspective view of the other cross-bar socket. Fig. VIII is a top View of the forming-block for forming the jaws at the top of the standards. Fig. IX is a vertical section at IX IX, Fig. VIII.

1 represents a street, and 2 a car-track.

3 are standards or legs which are shown pointed at bottom, so as to take a firm hold of the street. These legs I prefer to make of gaspipe for combined Alightness and strength; but they may be made of solid iron. Upon each leg 3, near the upper end, is a collar, 4, having ear or ears 5, forming members of a hinge, by which the collars are connected together. Thus the two legs at each end are jointed together at this point. The pintle 6 of thisjoint has ears 7, to which are jointed the ends of an arched tube or bar, 8. The hinge-joint at one end of the arched tube or bar8 is preferabl y connected by means of a common bolt or screw, 9, and then the parts can only be disconnected at thispointbyunscrewing thescrew or nut,while at the other end the hinge-joint has a detachable pintle, 10, having at the end a pivoted bar, 11, occupyinga diametric slot of the bolt and turning on a pintle, 12, so that it may be placed in line with the pintle or placed crosswise thereto, as shown in Fig. V. When in the former position, the pintle can be passed through the holes in the ears 7 and end of the arch 8, but when the locking-piece is crosswise to the bolt or pintle the latter cannot be drawn out of the ears.

13 is a spiral spring surrounding the pintle between the head 14 of the saine and one of the ears 7. The purpose of the spring is to keep the cross-bar 1l in contact with the ear 7. and thus keep it in a position crosswise to the pintle, To remove this pintle, it is only needed to push it into the position shown in Fig. V, and turn the cross-bar into line with the shank ofthe pintle, as seen in broken lines, when the pintle may be simply pulled out and the arch thus disconnected from the ears' 7. The arch has upon it one or more collars, 15, secured to it by set-screws 16, and having horns 17, forming a fork into which the hose may be laid.

18 is a strap, which is hinged to one of the horns 17 by a universal joint, 19 20, which allows the strap to be simply thrown back to open the fork for the reception of the hose or be putin a position spanning the fork, (by use of the hinge 19,) or be turned, as seen by broken lines in Fig. III, so that it will not project beyond the points of the horns, (by use of the hinge 20.) At the opposite end of the strap from the hinge is a crossvrib, 21, which, when the strap spans the fork, as seen in Fig. III, engages in a notch, 22, of thehorn and holds thel strap down upon the hose.

The parts of the legs. or standards 3 which are above the collars 4 have curved parts 23, which are formed to embrace the hose when the device is in use, such position being shown in Fig. I. The shape ot' the partsr23 is pret"- erably such as to spread out, as seen in Fig. I. The parts 23 have extensions 24, which are so bent as to form forks for the reception of the hose when the legs are'laid down on the ground preparatory to elevating the device. The collars 4 may be secured to the legs by pins 25 passing through one or both sides of the collar and the leg.

26 are collars, which may be fixed on the legs at any place between their lower ends and the collars 4. Pins 27 may be used to lix them in position in the same manner as the collars 4. The collar 26 upon one ofthe legs has a pivot, 28, with a head, 29.

30 is a cross-bar, one end of which swings on the pivot 28. The bar I prefer to make of IOC gas-pipe, which may be heated and Ilattcned at both ends. The collar 26 upon the other leg has a hook, 3l, fitted to receive the l'lattened end ofthe cross-bai-,with a lip, 32, projecting into the upper edge ol' the slot, so that after the end ofthe bar has been placed in the hook it may be moved toward the leg. so that the lip 32 takes over the top of the bar and prevents its upward movement. The bar is secured in this locked position by a set-screw, 33, whose end bears against the outer side ol' the bar and holds it in its position below the lip 32.

Si is a collar upon the cross-bar 30, secured in position by a set-screw.

are jaws upon the collar, through which passes a pintle-pin, 36, by which the braceleg 37 is hinged to the collar. rlhe upper part ot" the brace-leg is made tubular, and within this tube slides the foot-rod 3S, said rod being ixed in position by a set screw. The two ends el' the device are of exactly similar construetion, except as to their connection with the arch, as described. It will be seen that the two brace-legs will prevent the endwise sway oi' the device.

The arching of the arch-bar S is important for two reasons: It avoids abrupt bends in the hose at the forks 23, owing to the obtuseness ofthe angle between the arch and a vertical line at that point, and from this cause the passage of water will be impeded in a less degree. rlhe arched form allows the use of shorter legs than would be required if the bar S were straight, because it is necessary that the way should be clear to a certain height over the center of the track 2, owing to t-hat being the highest part ofthe car.

The operation is as follows: The device is brought to the ground in a folded condition and laid transversely across the track 2. In the l'oldcd condition cross-bars 30 are disconnected i'rom the hooks 3l, so that the cross-bars 30 will be in line with the legs,and the bracelegs 37 are also bent at the joint 36, so as to lie parallel with them, and the legs are folded longitudinally, so as to overlap each other beneath the arch. The hose is now laid on the folded frame between the parts 28 and the horns 17. A person takes hold of each end, and he lifts the device straight upward until the legs may be made vertical. Then the lower ends of the legs are moved apart and the free ends of the cross-bars 30 lixed in the hooks 31. Now the brace-legs are put iu position and the extension foot-bar 3S locked in position by the setscrcw 39. The parts 23, with their extensions 24, are described as formed in one piece with the legs or standards; but this construction is not essential, for they may be made in separate pieces from the legs and attached to the collars a.

In Figs. VIII and IX are shown enlarged views ofthe parts 23, with their extensions 24, and also the die or block a0, by use of which they are bent into the proper form. rlhe block has two holes, al, into which the ends or extensions 24 are inserted, one at a time, and bent down ilat on the block, a hammer or other means being used to force them down. The tube or rods are then swung around the stud 4t2, which is made ot' about equal diameter to the hose of a fire-engine. Then a pin, i3, is placed in the block and the tube or rod bent backward, so as to take the forni shown in Fig. VIII. The tube or rod should be heated before bending, and where a tube is used it is preferably lillcd with sand, (before bending.)

The combination, in a hose-bridge, oi' two pairs of legs or standards, each pair hinged together, and having extensions 23, adapted to hold the hose when the legs are ereet,with side extensions, 2i, adapted to hold `the hose while the legs are prone, and a connection hinged at the ends to the pairs of legs, substantially as and for the purpose set forth.
