NrTED STATES EDMUND LUNKENHEIMER, OF CINCINNATI, CHIC.
TH ROTTLE-VALVE.
SPECIFICATION' forming part ofLetters Patent No. 301,823, dated July 8, 1884.
Application tiled February 13, 1884. (No model.)
is automatically forced against its seat when closed, and similarly lifted from its seat when opened,by the manipulation of hand-lever,and partly in a novel arrangement of parts,whereby the valve may be set in any desired position, and. firmly secured against displacement by 2o jars or concussions of connecting-pipes.
In the accompanying drawings, Figure l is a sectional elevation on lines x :r of Fig. 3. Fig. 2 is a sectional elevation of valve-case on line 3/ y of Fig. 3. Fig. 3 is a plan ofmy improved valve. Fig. 4 is a plan of under side of cap or bonnet of case. Fig. 5 is a detached elevation of valve-stem. Fig. 6 is aplan view of wrench end of lever or handle. Fig. 7 is a detail of valve-disk, andFig. 8 is a detail of locking-lever.
Similar letters of reference indicate similar parts.
A is the valvecase, provided with a cap or bonnet, B, secured thereto by bolts or screws in the usual manner.
C C are threaded apertures for the connection of the usual steam-pipes. g
D is the valve-stem, provided with the radial arm D and a squared shank, d,which latter iits acorresponding opening in the wrench end of lever. The inner end of stem D is rounded off, or otherwise formed to fit the stepof bonnet B is similarly finished, so that when diskE is rmly pressed against seatb a steamtight joint is made, and no leak or transfer of steam or other fluid from one side of the valve to `the other can take place. Y Y
b b are curved ways on the under side of bonnet B concentric with orifice b2. erence to Figs. 2 and 4 it will be seen that the ways b b are sufficiently relieved to ,permit steam to pass behind or above the disk E, when the latter is swung around from its seat by the oscillation of stem D and arm D.
B is a neck preferably cast on the bonnet B, and threaded, as shown in Fig. l, to receive the screw-gland F,which gland and neck form Y a stufng-box to pack the stem D, in the usual manner of packing stems in ordinary steam andother stop valv'es.
The gland-F is of hexagon form outside, and tted to receive the box-wrench or hexagon recess g in the end of hand-lever G. The hand-lever G is provided with cheeks g g,which,in conjunction with the stops b3 b3, formed on cap B, limitthe oscillation of the-lever, and consequently of arm D and valve-disk E. The squared shank d of stem D fits the square opening giof hand-lever G, and the oscillation of the lever between the stops b3 b3 necessarily produces an oscillation of the stem D'and its arm D, and consequently an opening or closing movement of valve-diskE upon its seat b; but the screw-glandFitting the heXagon recess`g of hand-lever G, it is a consequence that as the lever is oscillated the gland is also turned on the threaded neck B in such a direction that whenthe disk E is swung off its seat on the ways b to open the valve the gland F is screwed down, and when the disk E is swung off the ways b to its seat vb to close the valve the gland F is screwed up. The cap-nut d being screwed rmly dow-n l upon the back of lever G, it follows that when ited motion of lever G and gland F, with a By ref- IOO fair depth of gland and neck, prevents perceptible wear of the threads by the oscillation of the gland.
The stem D and arm D may be of a single forging or casting, as shown, or the arm D maybe a separate member and keyed, pinned, or otherwise secured to the stem. rIlhe cheeks r/ g' of the lever G, in conjunction with the stops b b of cap B, limit the motion of lever and prevent any overstrain or injury of the wearing parts of the valve.
The stuffing-box, formed by neck B and gland F, may be furnished with a loose ferrule to compress the packing, after the manner of constructing the stuffing-boxes of common stop-valves.
H is a lockinglever, which is tapped to fit the threaded end of stem D, and displaces the capnut d when the valve is to be set in any desired position, and securely retained there against j ars or concussions, as in throttlevalves for portable and traction farm-engines. Then the locking-lever is used, the valvedisk E is swung off seat b, in the manner described,to any desired position, and the lever H, being firmly screwed down against back of hand-lever G, forces the valve-disk E hard up against scat b and ways b, and secures the disk in this position against possible accidental displacement.
One special advantage of my construction is the facility with which old or worn valves may be refitted by removing the bonnet B @and valve-disk E, and planing, filing, scrapways b b.
ated by hand-levers are not new, and I do not claim as my invention the simple operation of a stop-valve by a hand-lever.
Having described my invention, what I claim is- 1. The combination of an oscillating arm, as D', stem D, and hand-lever G with the disk-valveE and screw-gland F,whereby said valve-disk, by the oscillation of the moving parts, is automatically relieved from and forced against the seat Z1, in the manner substantially as described.
2. The combination of an oscillating stem, as D, arm D', and hand-lever G, provided with cheeks q g, with stops b3 b, substantially as and for the purpose specified.
3. The combination of a valvecase having a seat, b, a stem, D, ]'ournaled to rotate there' in, an arm, D', extending from the stem to swing when the latter is rotated, a valve-disk, E, on the arm, a swinging hand-lever, G, connccted with the stem to rotate the latter, and a locking lever, I-I, secured to the stem to bind against the hand-lever and lock the stem when rotated to the position desired, substantially as described.
4. The combination of the oscillati ng valvedisk E, seat b, and concentric ways b b,wl1cre by the said valve-disk is pressed upon both sides by steam when off its seat, in the manner and for the purpose substantially as specified. y
In testimony whereof I have signed my name to the foregoing specification in the presence of two subscribing witnesses.
