GAGE-COCK.
SPECIFICATION forming part of Letters'Patent No. 303,452, dated August 12, 1884. Application filed December 18, 1882. Renewed January '23, 1884. (No model.)
'cl'lamber.
My invention consists in the means hereinafter described and claimed for effecting said object.
To enable others skilled in the art with which myinvention is most nearly connected, I will proceed to describe its construction and operation.
In the accompanying drawings, which form part of my specification, Figure 1 is a side view of my improvement in water-gages. F i 2 is a longitudinal section of the same. Fig. 3 is a longitudinal section representing a modified construction of the same. Fig. 4 is a transverse section at line a: :0 of Fig. 2. Fig. 5 is a transverse section at line y y of Fig. 3.
Reference being had to the accompanying drawings, A represents the case, the bore of which from B to G is a straight cylinder or chamber, D, and from G toward the vent E is of conical form, so that the water and product' of condensation will flow toward said vent, and be discharged from the case A. By this arrangement of the inner walls of the case it will be washed out by the steam and water and not be liable to the clogging up common to valves of this class. The case A is provided with the ordinary screw-threads, G, for securing it in position in the end or head of the boiler. The inner end, H, of the case A is provided with a seat, I, for the valve J, which. seat and valve are of ordinary construction. The stem K is provided with spiral wings L, which are fitted to the bore of the chamber D. The outer end of the stem is provided with the usual cap or flange, m, and the extreme end a of said stem is made conical, for allowingthe stem to easily rotate when the operator is pressing against the conical part with the gagestick in the operation of testing the state of water in the boiler.
The conical end a may be constructed of 55 steel or other hard metal. Preference is given to this construction on account of being more durable and less liable to become impaired.
The modification of my improvement in water-gage valve shown in Fig. 3 consists in having the chamber D arranged in the forward part of the case A, and the spiral Wings L correspondingly arranged on the stem K, and constructing the case A in two or more parts, united by screw-threads at o. The part 1) can be made of ordinary gas-pipe. In all other respects the gage-valve is the same, and operates in the same manner, and its operation is similar to the ordinary gage-valve, eX- cepting that its stem rotates in the operation of testing and seating the valve differ ently at each testing, and in the peculiar form of the bore of the case A, for the purpose hereinbefore stated.
I am aware that gage-cocks in which the valve-stem is provided with spiral wings by whose action rotary motion is imparted to the valve, whereby the. latter is prevented from clogging and at the same time differently seated at each operation of said valve, have been already patented. Such a device I therefore do not claim; but
What'I do claim is I11 a gage-cock, the combination, with the stem K,provided upon its inner extremity with valve J, and having spiral wings L, extending radially from said stem for a short distance in front of said valve, of the case A, provided with cylindrical chamber C in front of the valve-seat I, and corresponding in its length with that of wings L, and having conical or enlarging chamber extending from said cylindrical chamber to the vent, substantially as described, whereby the draining of the valve-chamber is insured, as set'forth.
