HOSE COUPMNG.

SPECIFICATION forming part of Letters Patent in!)- 747,008, dated December 15, 1903- Application filed n 25, 1903.

To aZZ whom it may concern.-

Be it known that I, HARRY E. SMITH, a citizen of the United States, and a resident of Roslyn, in the county of Kittitas and State of Washington, have invented a new and Improved Hose-Goupling, of which the following is full, clear, and exact description.

The object of this invention is to provide novel details of construction for hose-couplings which are simple and practical, afiording means for conveniently and quickly connecting two sections of the hose-coupling in a reliable manner and permitting said sec-' tions to be manually disconnected with case when this is desired and which may be employed to couple onto a fire-hydrant as well as an ordinary hose.

The invention consists in the novel construction and combination of parts, as is hereinafter described, and defined in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the improved hose-coupling, showing the two coupling'sections disconnected and secured upon the end portions of the hose-sections. Fig. 2 is a longitudinal sectional view of the hosesections and the improved coupling thereon in coupled condition, the section being substantially on the line 2 2 in Fig. 3. Fig. 3 is a partly-sectional end face view of one halfsection of the hose-coupling,the section being substantially on the line 3 3 in Fig. 4. Fig. 4 is a partly-sectional side view of one half-section of the hose-coupling seen in the direction of the arrow 00 in Fig. 3. Fig. 5 is a detached perspective view of a nut-block that is a detail of the invention, and Fig. 6 is a partly-sectional plan view of novel details of the coupling substantially on the line 6 6 in Fig. 3.

connection of said hose-sections by detachably securing the male and female sections ofthe coupling together. i i

The male coupling-section consists of a cylindrical thimble, designated in its entirety by the reference characters 10 10 10 The p rtion 10 of the male coupling-section exte ds from one end thereof, having a suit- .a le length, and upon it is formed the ext .rnal thread a, which terminates at the colar 10*, that projects radially and adords a ihoulder a where the thread a terminates. From the collar 10 the thimble-section 10 is extended axially coincident therewith, the interior diameter of this portion of the male dgupling-section being greater than that of ii e bore in the collar and threaded part 10.

" The inner surface of the thimble-section 10 is rendered undulating to make it hite upon the hose A when the latter is inserted, and, as shown in Fig. 2, the inserted end portion of the hose is embedded in the undulations by the insertion of a bushing-ring 12, that when driven into the end of the hose-section A expands it sufficiently. to effect a secure connection of the thimble therewith and produces a water-tigl1t joint. Two studs 10 are projected oppositely from the collar 10* for engagement with a suitable wrench to aid in effecting a water-tight connection between the two sections of the coupling.

The remaining half-section of the hosecoupling comprises the following details: A thimble 11 of equal diameter with the portion 10 and provided with a collar 11 is rendered undulating on its inner surface for a portion of its length, wherein the hose-section B is secured water-tight by a bushing-ring 12, that is similar to the bushing-ring 12, said hose-section havingits true end located at a suitable distance from the end of the thimble whereon the collar 11 is formed, and within said end portion of the thimble l1 a 'thread is formed.

The female half-section proper of the hosecoupling consists of a main ring 11, from which extends at one end an integral circular .flange 11, that is of less diameter than the main ring and is externally threaded, the thread I) having such a pitch as will permit the internally-threaded end of the thimble 11 to be screwed thereon. It will be seen that the junction of the main ring 11 and flange 11, of considerably less diameter endwise, produces an annular shoulder c, that is an end wall of the main ring and against which the thimble 11 will abut when it is fully screwed upon the flange 11. Furthermore, it will be noticed that there is an annular wall a, formed internally between the main ring 11 and the annular flange 11, that defines their point of interior junction. On the main ring 11 studs 11 are formed for engagement with a spanner-wrench. A projection 11 is formed on the periphery of the main ring 11, of equal width therewith, and centrally in said projection a slot 01 is formed radially. The slot d is cruciform in crosssection, as shown in Fig. 6, and in it is loosely fitted a T-shaped nut-block 13, which is thus adapted to slide toward or from the axis of the circular portion of the ring 11, and it will be seen that the slotted projection 11 provides a housing-frame for the nut-block,which block may have a projection 13 upon the outer end to permit-it to be conveniently manipulated.

Upon the rear side of the nut-block 13 an outwardly-projecting flange e is formed, that may traverse the portion of the cruciform slot in which it is located, and, as is shown in Figs. 2 and 4, this part of the slot cl does not extend completely through the projection 11 but provides a seat at its bottom whereon the expansion -spring e may seat, and thus be adapted to press on the flange 6.

Upon the lower end of the nut-block 13 a screw-thread g is formed of'an equal pitch to that of the thread a on the male thimble-section 10, and oppositely on the inner surface of the main ring 11 a segmental screw-thread h is formed, which is also similar in pitch to that of the thread a, so that when the thimble-section 10 is loosely introduced within the main ring 11 the thread a will mesh with the segmental thread It and the thread on the innor end of the nut-block 13 may be caused to engage with the thread a if the nut-block is depressed.

A recess i is formed in one side of the nutblock 13, and a threaded detent-pin 14 is screwed through a tapped hole in an adjacent side wall of the housing-frame 11, so asto engage its inserted end within the recess, thus adapting the pin 14 to prevent the spring e from pressing the nutblock out of the housing-frame, the extent of outward movement of the nut-block being indicated by dotted lines in Fig. 3 and the full depression of the nut-block by full lines in said figure.

In the side wall of the housing-frame 11 and nearly opposite the recess 2' a lateral perforation m is formed, and a socket m of equal diameter and a suitable depth is formed in the side of the nut-block nearest the perforation m, the socket and perforation being alined when the nut-block is depressed fora threaded engagement with the threaded end portion 10 on the male coupling-section. A

coiled spring 15 is seated in the socket m, and on the said spring a locking-pin 16 is seated and normally pressed by the spring, so as to project an end portion of the pin out of the 'socket. In the perforation m a push pin 17 is held to slide by a cross-bar 0, that is held firmly in the wall of the housingframe 11 so as to pass loosely through a longitudinal slot 0, formed diametrically in the push-pin.

As shown in Fig. 3, if the nut-block 13 is pushed in ward when the locking-pin 16 comes opposite the perforation m in the housingframe 11 the pressure of the compressed spring 17 will serve to push the locking-pin outward and into the perforation ma distance determined by the contact of the cross-bar 0 upon the inner end wall of the longitudinal slot in the push-pin 17, that is pressed outward by the locking-pin. When a coupled connection of the two sections of the improved hose-coupling is to be effected, if the nutblock 13 is looked in depressed adjustment, as shown in Fig. 3, pressure on the push-pin 17 will release the locking-pin 16 from interlocked engagement with the housing-frame 11 and permit said nut-block to be thrown outward by stress of the expansion-spring e, thus disposing the threaded end of the nutblock within the housing-frame, this adjustment being necessary to permit an interlocking connection of the coupling-sections. The threaded end portion 10 of the male couplingsection is now inserted within the main ring 11 and engaged loosely with the segmental screw-thread h, thus disposing the threaded end of the male coupling-section within the main ring 11 in loose contact with the packing-ring 0 that is seated upon the annular wall 0, that is the bottom of the main ring. Upon completing the insertion of the threaded portion 10 within the main ring 11 it may be quickly engaged by the threaded end of the nut-block 13 by pressure applied upon the outer end of said nut-block, as this will depress the block, causing the thread 9 thereon to be embedded within the turns of the thread a, and simultaneously the locking-pin 16 will be spring-pressed outward, so as to enter the alined perforation m, and thus secure the thread in the nut-block and the segmental thread It in engagement with the thread a.

It will be seen that by the application of a suitable wrench upon the studs 11 while the male coupling-section is held from turning a partial rotation of the main ring 11 on the thimble-section 10 will force the true end of said end of the male coupling-section into close engagement with the joint-ring c and thus effect a water or steam tight coupled engagement of the two half-sections of the improved hose-coupling, an inward pressure on the push-pin 17 serving to release these sections of the coupling in an obvious manner. Having thus described my invention, I claim as new and desire to secure by Letters Patent-- IIO 1. A coupling comprising a male section, threaded at one end, a female section having a main ring, a segmental thread in the main ring, a nut-block held to slide radially in the main ring, and means for detachably securing the nut-block pressed inward.

2. A coupling comprising a male section, threaded at one end, a female section having a main ring, a segmental thread in the main ring, an outwardly spring-pressed nut-block, slidable in the main ring and having a threaded inner end, means for holding the nut-block pressed inward against the stress of the spring, and means for limiting the outward movement of the nut-block.

3. A coupling comprising a male section, externally threaded at one end, means for securing a hose in the opposite end, a female section having a main ring, a segmental thread in the main ring, a housing-frame on the main ring, opposite the segmental thread, a nut-block held to slide in the housing-frame and threaded at its inner end, a spring adapted to press the nut-block outward, means for limiting the outward movement of the nutblock, and detachable means for locking the nut-block when moved a proper distance inward.

4. A coupling comprising a thimble-like male section, an external thread on an end portion of the thimble, means for securing a hose in the opposite end, a female section having a main ring, a segmental thread in said main ring, a housing-frame on the main ring, opposite the segmental thread, a nutlolock held to slide in thehousing-franie toward and from the segmental thread, a thread on the inner end of the nut-block, a detentpin extended from one side of the housingframe into a recess in the nut-block, for limiting its sliding movement, an expansionspring adapted to press the nut-block outward, a slidable spring-pressed locking-pin held in a socket in the nut-block, and which may be adjusted opposite a perforation in the housing-frame, a push-pin held to slide in said perforation, for engagement with the outer end of the locking-pin, and means for securing the main ring on a hose.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
