stow-OFF VALVE. I

. SPECIFICATION forming part of Letters Patent No. 645,696, dated March 20,-1eo0..'

Application and J'u1y10,1899 SerialNo. 123,315. (Nomodelo' To aZZ whom it may concern; 1

Be it known that I, CHARLES HENRY Torr, a

citizen of the United States, residing at Huntington, in the county of Oabell and State of West Virginia, have invented a new and useful Blow-Oh? Valve, of which the following is a specification. I

This invention relates to three-way blowoff valves, and is especiallydesigued for use in connection with range-boilers, so as to conveniently clean out the latter, the water-back in the range, and the pipe connections there between. I

A further object is to provide a sectional structure whereby the valve-casing may be taken apart, so as to replace the valve. when worn andalso to change the relative arrangeing the valve for use in connection with various other pipe-line systems. a

To these ends the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended. claims, it being understood that changes in the form, proportion, size, and the minor details of construction may be made within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the present inven tion.

In the drawings, Figure 1 is a perspective view of a range-boiler having the present blow-01f valve applied thereto. Fig. 2 is a longitudinal sectional view of the valve. Fig. 8 is a similar View showing a modified form of valve-casing. z

Corresponding parts in the several figures of the drawings are designated bylike characters of reference.

Referring particularly to Fig. 2 of the drawings, it will be seen that the valve comprises a substantially L-shaped casin g 1, having the inlet-passage 2 and the discharge-passage 3. arranged at substantially rightanglesand forming a valve-chamber 4, located between said passages. The inlet-passage is prefer,- ably internally threaded, so as to receive the return-pipe 5 from the water-back, as best shown in Fig. 1 of the drawings, and the discharge-passage 3 is preferably externally threaded so as to be fitted into the boiler 6, although this relative arrangement may be changed so as to accommodate the valve to the position in which it'is placed. -The discharge branch is provided at its inner end with a valve-seat 7, projecting into the inte- I rior of the casing 1, and alinedtransversely I opposite said discharge branch is another dis,- charge-opening 8, surrounded by an outwardly-projecti n g exte mally-threaded flange or collar 9.

Communicating with the discharge opening Sis a substantially L-shaped discharge branch 10, having its inner end externally threaded and provided with an annular shoulder 11. Removably fitted to the inner threaded end of the branch 10 is a gland 12, having its inner end formed into a valve-seat 13. The ex terior of this glandis tapered or inclined toward the innerend thereof, thereby giying the gland a substantially-conical form, so as to be wedged firmly against the similarly inclined r beveled interior walls 14 of the collar 9. Located near the outer end of the gland 12 is an outer annular shoulder or flange 15, to which is swiveled a coupling-ring 16, which embraces the gland and the collar 9 and is in threaded engagement with the latter, so as to hold the gland in position and wedge the same within the discharge-opening 8. Thus it will be seen that the gland and the branch 10 are removably connected to the casing 1, and by loosening thecoupling-ring 16 said branch may be turned axially, so as to change the relation of its outer discharge end with respect to the branches 2 and 3.

Projecting outward from the branch and alined with the valve-seats 7 and 13 is an internally-threaded housing or extension 17,

provided atits outer end with a suitable stufiing-box 18 and receives a valve-stern 19, having the external threads 20 fitting the internally-threaded portion of the extension and a hand-wheel 21, located at the outer end of the stem. Theinner end or the stem is nor-. mally located intermediate of the valve-seats 7 and 13 and is provided with an angular portion 22, to which is fitted a suitable valve 23, so as to prevent turning of the latter upon the stem, and the valve is held uponthestem by means of. a nut 24 in the common or usual manner. Thus it will be seen that the valve 23 may be seated upon either of the valveseats 7 or 13, so as to open or close the respective discharge-passages 3' and 10.

To illustrate the application of the present valve, I have shown in Fig. 1 a common or ordinary boiler 6, having at its upper end the usual cold-water-inlet pipe 25 and the hot-water-discharge pipe 26. Connected to the lower end of the boiler is the usual supply-pipe 27, which communicates with the water-back of the range, from which latter the hot water is returned into the boiler through the usual pipe 5. The discharge branch 3 of the valve is fitted into one side of the boiler, and the hot-water-return pipe 5 is fitted to the inlet branch -2, and the valve 23 being normally seated against the valve-seat 13 there is a continuous passage from the boiler through the lower pipe 27 to the water-back and returning through the pipe 5, the inlet branch 2, and the discharge branch 3 into the boiler. \Vh'en it is desired to clean out the boiler, the water-back, and the pipe connections therebetween, the valve-stern is screwed inward, so as to seat the valve 23 upon the valve-seat 7, thereby closing the discharge branch 3 and vopening communication between the branches 2 and 10,whereby instead of returning intothe boiler the water will discharge through the branch 10, from which it may be conveyed to any desired point.

I In Fig. 3 there has been illustrated the usual globe-valve form of casing 28, having the inlet-passage 29 alined .with the dischargepassage30, so that the valve is accommodated for use in connection with a single length of pipe, and is therefore not restricted to an angular connection. Otherwise this latter form of valve is a duplicate of the former and permits of the discharge branch 10 being adjusted in the manner hereinbefore described.

.VVhat I claim is- 1. A valve, comprising a casing having an inlet and an outlet passage, a removable gland having a valve-seat at its inner end, and detachably fitted within the outlet-passage, a coupling-ring swiveled upon the gland, and having a screw-threaded connection with the outlet-passage, and a substantially L-shaped discharge branch removabl y connected to the outer end of the gland, substantially as and for-the purpose set forth.

' 2. A valve, comprising a casing having an inlet and an outlet passage, a substantiallyconical gland having a smooth exterior and fitting the smooth interior-of the outlet-passage, a coupling-ring swiveled upon the outer end of the gland, and having a screw-threaded connection with the exterior of the outletpassage, and a substantially L-shaped discharge branch detachably connected to the outer end of the, gland, substantially as and for the purpose .set forth.

3. In a valve, the combination with a casing having an inlet and an outlet passage, of a gland detachably fitted within the outletpassage, and having a valve-seat at its inner end, a coupling-ring swiveled upon the outer end of the gland, and having a screw-threaded connection with the outer end of the outlet-passage, a substantially L- shaped discharge branch rernovably connected to the outer end of the gland, and provided with an interiorly-threaded extension alined axially with the valve-seat, a valve-stem fitted within the extension, and a valve carried by the stem, located within the casing, and adapted to be seated upon the valve-seat, substantially as shown and described.

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

CHARLES HENRY TOPP. Witnesses:
