IMPROVEMENT IN OMPRESSION'CGCKS.
i Specification forming part of Letters Patent No. 133,558, dated December 3, 1872.
To all whom it may conce/m:
Be it known that we, HENRY J. BAILEY and. JOHN PORTEOUS, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Compression-Cocks; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing making a part of this specification, in which- Figure l is alongitudinal vertical section of a compression cock illustrative of our improved construction; and Fig. 2, by alike view, shows a portion of the same devices as applied to a cock` having a rotating valve.
Like letters of reference indicate like parts in each.
Our invention consistsin the features of construction and combination, hereinafter set forth and claimed, whereby we render compressioncocks more economical in construction and efiicientl in operation.
Heretofore in the manufacture of compression-cocks an internal thread has commonly been cut in the body ofthe valve-case, to provide for which the body had to be made of greater thickness than would otherwise be required. It had to be thick enough not only for the cutting of the thread, but alsoto prevent its being bent or bruised in chucking or fastening in the lathe preparatory to the chasing of the thread therein.
We have remedied this defect, as well as otherwise improved the construction of the cock.
To enable others skilled in the art to make and use our improvement, we will lproceed to describe its construction and mode of operation, and first with particular reference to Fig. 1.
B B represent the through-way pipe, with'a valve-seat at b formed by a diaphragm in the usual way. D is the body of the valve case or chamber, which, as itis notthreaded, can, for the reasons already mentioned, be made much lighter or thinner than has heretofore common ly been done, with a consequent saving of metal. The cap D is screwed on in the usual l way. A leather or gum washer, a, having a hole for the valve-spindle, is placed on the top of the case D,l and held there by the cap D'.
The valve-spindle g g1 passes through both the cap D and washer a, and the space between the cap and washer is occupied by a'ilange, Y
g2, made on the stem, itsupper and lower faces being adapted in shape to the lower and upper faces of the cap and washer, respectively,
so that as the washer a is pressed up a tight joint may be formed between it and the fiange g2. Inside the body or case D we insert a bush,
c, internally thrcaded,and seated by a shoul,
der, as shown, or in other suitable way. It is prevented from rotating in the case D by a feather and groove or by a key, c', which occupies a half-circle groove in bush and case f each. On a shoulder made inside the bush c at its upper end we place a spring, s, preferably of spiral forni, as shown, with its upper i end bearin g against the washer a, so as to keep it pressed up against the .flange g2, as the latter or the washer, or both, may wear away from friction on each other. The lower end g1 of the spindle is square or of other than cylindrical form, and enters a correspondinglyshaped socket in the upper end of the plug e. The upper end of this plug is externally threaded so as to screw up and down in the bush c. At the base ofthe screw-thread is a flange, e', packed, if desired, by a gasket, s1, so as, when the plug e is screwed up and the valve raised lthe desired distance, to stop its upward mo tion and at the same time prevent the flow of the fluid into the space above the plug e. The
plug at its lower end is bored out so as to re- I ceive` the headed, stem a of the disk-valve m'. A screw or pin, o, is inserted through the side of the lower end of the plug e so that its inner end shall come under the head of the stem n, andA thereby secure the valve m to the plug in such a way that while the plug rotates in go ing up and down the valve m may be screwed down onto and up off its seat b in a vertical line without rotating. Y x
The devices are operated in theusual way by the use of the hand-wheel or T h.
In Fig. 2 the devices indicated by the same letters have the same construction and operI ation as in Fig. l, except that the valve m, in stead of being loosely attached to the plug e so as to be seated and unseated by moving in a direct line, is rigidly fastened to the plug e so as to rotate therewith.
e; but the preferable construction We consider' to be that shown in Fig. 1.
What We claim as our invention, and desire to secure by Letters Patent, is-
1. The bush c and Washer a, with or With-v out the interposed spring, in' combination with the spindle g g1, case D, and plug e, substantially as set forth.
2. The plug e having the ange e', in combinetion with the spindle gl and bush c, substantially as set forth.
'a rssss 3. The bush c, in combination with the'spring s, Washer a, and collar g2, substantially as described, with reference to Fig. 1.
4. The loose valve m, in combination with the plug e having the projecting flange e', substantially as described, with reference to Fig. 2.
In testimony whereof We, the said HENRY J. BAILEY and J ORN' PoRrEoUs, have hereunto set our hands.
