HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 714,243, dated November 25, 1902.

Application filed August 25, 1902.

To all whom it may concern:

Be it known-that 1, JAMES F.SARoENT,Jr.,a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of 'Michigan, have invented a new and useful Hose-Coupling, of which the following is a specification.

This invention relates to devices employed for immovably coupling the adjacent ends of to sections of hose, more particularly to that class of devices employed for the purpo'seof mendingbrokenor severed hose, and has for its object'the construction of a-device which may be readily and quickly applied without the employment of extraneous implements other than an ordinary hammer or other similar tool or implement; and the invention consists in a shank preferably tapered from the center toward the ends and provided with a centrally-disposed annular rib and adapted to be inserted into the adjacent ends of the hose-sections and two collars engaging the shank on opposite sides of the rib and with lugs spaced apart and extending in opposite directions and preferably interlocking and adapted to be forcibly engaged with the opposite hose-sections.

Other novel features of the invention will appear in the annexed description and be 0 specified in the claims.

In the drawings illustrative of the invention, Figure 1 is a side elevation of the device applied. Fig. 2 is a vertical longitudinal section. Fig. 3is aperspective viewof the shank detached. Figs. land?) are perspective views of the gripping-collars detached. v

The improvement consists in a central shank or sleeve 10, preferably tapering in opposite directions from the central part toward the ends, and with a centrally-disposed annular rib l1 and preferably with annular end I ribs 12 13.

The sections of hose are represented, re-

spectively,at 14 15 and are adapted to engage 5 the oppositeends ofthe shank 10 and be forced thereon, the tapered form of the shank expanding the hose sections and causing them to grip the shank closer and obviate the tendency to work loose. The shank thus 5o exerts a constantexpanding force upon the Serial No. 120,977. (No model.)

this action and materially increase the grip caused by the resiliency ofthe hose.

Encircling the shank on opposite sides of the central rib 11 and betweenthe rib and the adjacent ends of the hose-sections are collars 16 17, the collar 16 provided with spaced lugs 18, extending over the rib 11 and also over the end of the opposite hose-section 15, while the collar 17 is likewise provided with spaced lugs 19,extending between the lugs 18 and over the end of the hose-section 14, as indicated in Fig. 1.

The extremities of thellugs 18 19 are provided, respectively, with inwardly-depending spurs 20 21, and when in position on the hose, as shown in Figs. 1 and 2, the lugs 18 19 will be forcibly bent inward radially of the collars, and thus tightly compress the hose-sections against the shank and form a very strong holding meansthereto and locking the parts all firmly together. Thiscompression of the hose forces the hose material downward between the ribs 12 13 and the body of the shank,

as indicated in Fig; 2, thereby greatly increasing the grip and entirely obviating any tendency of the hose-sections to work loose from the shank.

The spaces between the lugs 18 will be'sufficient to receive the opposite lugs 19 on the opposite collar, and the spaces between the lugs 19 will be sufficient to receive the lugs 18 on the collar 16, as indicated in Fig. 1, the two-lugged collars thus being capable of being interlocked when in position, as indicated in Fig. 1, and adapted to be firmly locked to the hose and likewise firmly lock. the adjacent hose-sections to the coupling-sleeve. This makes a very simple hose-coupling and may be adapted to any size of hose and will firmly unite them and enable them to resist any strains to which they would be naturally subjected while in use and will form a watertight joint. By this simple means a broken hose may be very quickly and readily mended by severing the hose at the break and properly trimming the broken ends and forcing them upon the opposite ends of the shank, the reversely-disposed collars 16 17, with their reversely-disposed spurs interlocking, having been previously placed in position, as above noted, and the lugs 18 19, with their depending spurs 2O 21, forcibly engaged with the hose.

The lugs 18 19 may be bent downward in engagement with the hose by any suitable implement, preferably with a hammer, when the action will be complete.

To detach the hose, it is only necessary to bend the lugs 18 19 outward, and if only one section is to be removed it is only necessary to detach the lugs holding that particular section of hose.

Any required number of the lugs 18 may be employed, but generally four will be sufficient, as shown.

The collars 16 17 are precisely alike and will therefore be interchangeable and may be manufactured very cheaply of sheet metal and of any weight or gage desired.

When completely united, the coupling presents no obstructions which may catch upon grass or weeds or become charged with earth or other foreign matter when dragged over the ground. This is a very important feature of the invention and adds very materially to its advantages, efficiency, and usefulness, as in many instances in dragging hose over the ground the couplings catch upon obstructions and cause the rupture of the coupling. With this device, however, such accidents will be obviated.

Another very important feature of this invention is found in the fact that the diameter of the coupling being substantially the same as that of the hose permits the uninterrupted flow through the hose either of steam, water, or other liquid or air.

Having thus described the invention, what is claimed is 1. A hose coupling comprising a shank having a centrally-disposed annular rib and adapted to engage the adjacent ends of sections of hose, collars engaging said shank on opposite sides of said rib and having spaced lugs adapted to be reversely extended and forcibly engaged with the opposite hose-sections, substantially as described.

2. A hose-coupling comprising a shank havingreversely-tapered ends and a centrallydisposed annular rib and adapted to engage the adjacent ends of sections of hose by said tapered ends, collars engaging said shank on opposite sides of said rib and having spaced lugs adapted to be reversely extended and forcibly engaged with the opposite hosesections, substantially as described.

3. A hose coupling comprising a shank having a centrally-disposed annular rib and with annular ribs upon its ends and adapted to engage the adjacent ends of sections of hose, collars engaging said shank on opposite sides of said rib and having spaced lugs adapted to be reversely extended and forcibly compressed in engagement with the hose between said end ribs and said central rib, substantially as described.

at. A hose coupling comprising a shank having a centrally-disposed annular rib and adapted to engage the adjacent ends of sections of hose, collars engaging said shank on opposite sides of said rib and having spaced lugs adapted to be reversely interlocked and oppositely extended and forcibly engaged with the opposite hose-sections, substantially as described.

5. A hosecoupling comprising a shank having a centrally-disposed annular rib and adapted to engage the adjacent ends of the sections of hose, collars engaging said shank on opposite sides of said rib and having spaced lugs with their extremities bent inward and adapted to be reversely extended and forcibly engaged with the opposite hosesections, substantially as described.

6. A hose coupling comprising a shank having a centrally-disposed annular rib and with annular ribs upon its opposite ends and adapted to engage the adjacent ends of sections of hose, collars engaging said shank on opposite sides of said rib and having spaced lugs with their extremities bent inward and adapted to be reversely extended and forcibly engaged with the opposite hose-sections between said end ribs and said central rib, sub stantially as described.

7. In a hose-coupling, the combination of a shank having a centrally-disposed annular rib, hose-sections engaging the opposite ends of said shank, a collar engaging said shank between said rib and the adjacent end of one of said sections of hose and with lugs extending therefrom and adapted to be forcibly engaged with the other of said sections of hose, a collar engaging said shank upon the opposite side of said central rib and having lugs extending therefrom and adapted to be forcibly engaged with the opposite sect-ion of hose, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
