FIRE-HOSE Noz'zLE.

SPECIFICATION forming' part 0f Letters Patent NO. 660,147, dated October 23, 1900.

Application filed December 27, 1899. Serial No.741j'713; (No model.)

To all, whom, it may concern:

Be it known that I, BENJAMiN CHAPMAN CRANE, a citizen of the United States, residing at Montesano, in the county of Ohehalis and State of Washington, have invented a new and useful Fire-Hose Nozzle, of which the following is a specification.

The invention relates to improvements in fire-hose nozzles.

The object of the present invention is to improve the construction of fire-hose nozzles, more especially that shown and described in Patent No. 626,596, granted to me June 6, 1899, and to provide a simple, inexpensive, and efficient device adapted to be readily applied to a nozzle and capable of arresting the rotary motion of a stream of water and adapted also to serve as a guard or strainer to prevent anything from coming in contact with the valves and clogging and interfering with the operation of the same.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a longitudinal sectional view of a device constructed in accordance with this invention and shown applied to the nozzle illustrated in the said patent. Fig. 2 is a transverse sectional view. Fig. 3 is a longitudinal sectional view illustrating a slight modiiication of the device.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

l designates a tube arranged within a casing 2, constructed in accordance with the patent above referred to, and thel said tube 1, which is designed to be introduced into the said casing when the removable side thereof is detached, is provided at its inner or rear end with exterior screw-threads 3, which engage corresponding screw-threads 4 of the interior of the extension or neck of the casing 2, as clearly illustrated in Fig. l of the accompanying drawings. The projectiug'portion or neck 5 is provided with interior screwthreads 6 for the attachment of a hose-pipe, and the said screw-threads 4,which are smaller than the screw-threads 6, terminate short of the same to provide a shoulder 7, against trated in Fig. 1 or the screw-threads of any-` other ordinary fire-hose nozzle.

Within the tube 1 are arranged longitudinal partitions 9, crossing each other at the longitudinal axis of the tube and disposed radially thereof to divide the said tube into quad rantshaped passages, as clearly illustrated in Fig. 2 of the accom panying drawings. These partitions, which are adapted to arrest the rotary motion of a stream of Water, are slightly tapered or wedge-shaped, their sides l() being forwardly or outwardly converged t0 conform to the configuration of the tapered interior of the tube, whereby the said partitions are wedged therein, and the outward pressure of the water will operate to hold them in place. Besides operating to counteract the rotary motion of the stream of water passing through the hose and nozzle the'device also serves as a guard or strainer attachment to hold in check anything which might clog and interfere with the operation of the valves. .The

partitions, which may be formed integral with each other or interlocked in any suitable manner, are readily removable from the tube when the latter is detached from the casing of the nozzle.

It will be seen that the device, which is exceedingly sim ple and inexpensive in construction, is adapted to be readily applied to nozzles and that it is capable of arresting the ro-v tary motion of a stream of water and of preventing the same from being broken up when it enters the cylindrical casing, whereby a straight stream of increased power is caused to issue from the nozzle. It will also be apparent that besides operating to arrest this rotary motion of the water the device serves as a guard or strainer to prevent anything from entering the casing which might clog or interfere with the operation of the valves.

What is claimed isl. The combination with a hose-nozzle pro- ICO vided with a cock or Valve and having screwthreads in rear of the saine,4 of a detachable device comprising a tube exteriorly threaded to engage the said screw-threads and located in rear of the cock or valve, and removable partitions arranged Within the tube', said partitiops beingadapted to arrest the rotary` 1110.-4 tion of astream of Water and forming a guard or strainer to protect the cock or valve, substantially as described.

2. The combination of a hose-nozzle having a valve and provided with interior screwthreads and having a shoulder in rear of the A screw-threads, a tube exteriorly threadedto engage the screw-threads and fitting against the said shoulder, said tube being located in rear of the valve, and partitions arranged Within the tubes, substantially as described 8. The combination cfa nozz'le having a cock or valve, a-tube detachably secured Within the nozzle and located ata point in rear of the cock or valve, said tube being provided with a tapering interior,A and the partitions having tapered or converged edges and fitting within the tubeto arrest the rotary motion of a stream of Water and f'rming a guard or strainer to `prevent the valve or cock from becoming clogged, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in `the presence of two Witnesses.

BENJAMIN CHAPMAN CRANE.
