HOSE-PIPE FITTING.

SPECIFICATION forming part of Letters Patent No. 475,213, dated May 17, 1892.

Application filed July 30, 1891- Serial No. 401,120. (No model.) Patented in France May 30,1891, No. 213,804, and in Belgium May 30, 1891, No. 95,051.

To aZZ whom it may concern:

Be it known that I, WILLIAM FRASER, a subject of the Queen of Great Britain and Ireland, residing at S parkb rook, near Birming- 5 ham, in the county of Warwick, England, have invented certain new and useful Improvements in Hose-Pipe Fittings, (for which I have obtained Letters Patent in France, No. 213,804, dated May 30, 1891, and in Belgium,

[ No. 95,051, dated May 30, 1891;) and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

I This invention has reference to connections and fittings used in connection with hosepipes; and it consists of certain improvements therein, hereinafter described and claimed.

In the drawings, which serve to illustrate,

my invention, I show these improvements.

Figure 1 is an elevation, partly in section, of the improved fitting for fixing the hosepipe to an ordinary house-tap or other watersupply conduit. Fig. 2 is an elevation showing the improved fitting for coupling together two lengths of hose-pipe, and Fig. 3 shows the invention used at the end of the hose-line combined with the delivery-nozzle.

The invention mainly consists of an automatically-fixing connection by which when a hose-pipe is placed over the metallic throat of the connecting pipe or piece it is caught automatically by a spring-pressed gripping-collar which slides on the throat-pipe and is held 5 firmly, and a water-tight connection is thus automatically made.

In the drawings, a is the throat-pipe, having at one end or at each end, as the case may be, a bulbous part b, over which the tube is placed 0 when connecting it up.

0 are the sliding spring-pressed grippingeollars, and d are the springs by which the collars c are automatically pressed up into position and grip the hose-pipe, which is des- 4 5 ignated 6.

It will be seen that the collars e have necks c, which are the parts which slide directly on the throat-pipe a, and that they are flanged over at c to receive and form seats for the ends of the springs d.

The throat-pipe at is provided with projecting ring I), which .forms a stop, against which the neck c of the collar 0 is pressed by the springs d and by which such collars are held in position. r:

The coupling shown in Fig. 3 forms-partot' the distributing-nozzle, and this part consists of a body h, having a rod 2' cast in it, provided with threadedparts t and 11 a rose or spraying-plate it, held on by the nut 70, a jet- 6o hood Z, having a jet-aperture Z, (which fits and screws either on the screwed end i' or 11 according to whether it is desired to use afine spray or a single jet,) and a ball-valve m by which the water may be stopped and regulated, as desired. The seat onwhich theballvalve 1% sits is designated n, and it is normally pressed toward it by the Water; but a spring n may be used as Well, if desired. The Valve m is worked through the bell-crank lever 0, pivoted at 0 by the press-button p, by depressing which the valve is opened and water allowed to flow.

r is the washer of leather, rubber, or other equivalent material by which a Water-tight joint is made between the edge of the roseplate is and the body it and also the edge of the nozzle-hood Z and the body, and s is a plate secured to the hood-nozzle and having water-passage apertures therein and by which it is screwed onto the end 2" or Z The end t, (shown in Fig. 1,) by which the coupling is attached to an ordinary tap-mouth or end of a pipe, is well known, and merely consists of a ring of india-rubber 25, held in 8 the hollow neck 29, and is pressed onto the tap mouth or pipe in the well-known way.

The throat-pipe a is made of ordinary piping, with its ends I) pressed out in any suitable known way, while the collars c are stamped out of sheet metal in the well-known method of stamping. WVhen making double couplings, as in Fig. 2, one end is first formed on the pipe, and the collars and spring 0 and d are then put on and held back,and then the 5 other end I) is formed, and the coupling is completed.

In operation to connect a hose-pipe to the coupling one end collar 0 is pressed back by the hand and the pipe slipped over the bulb- IOO ous end I) of the throat-pipe a, and then the collar is let go and the spring d presses it onto the bulbous part b and retains it there,

collar 0 thereon, and a spring (1 by which said collar is pressed outward, and when the hose is put on the bulbous end an automatic coupling and water-tight joint is effected without screwing, turning, or other manipulation, substantially as described.

In testimony whereof I hereunto affix my signaturein presence of two witnesses.
