PATENT OFFICE.
EDMUND H. LUNKEN, OF CINCINNATI, OHIO, ASSIGNOR TO THE LUNKEN- HEIMER COMPANY, OF CINCINNATI, OHIO.
VALVE-SEAT.
SPECIFICATION forming part of Letters Patent No. 794,808, dated July 18, 1905.
Application filed January 11, 1905. Serial No. 240,651.
To 0065 whom, it may concern:
Be it known that I, EDMUND H. LUNKEN, a citizen of the United States, residing at Cincinnati, Ohio, have invented certain new and useful Improvements in Valve-Seats, of which the following is a specification.
My invention relates to improvements in valves, and in my present embodiment thereof I have illustrated it in connection with a globe and angle valve.
The invention concerns more particularly a renewable valve-seat and the means wheieby it may be placed in position and removed from the valve-casing.
The invention consists in the features and combination and arrangement of parts hereinafter described, and particularly pointed out in the claims.
In the accompanying drawings, Figure 1 is a horizontal sectional view on the line 1 1 of Fig. 2 with the valve trimming omitted. Fig. 2 is a central vertical sectional view of a globe-valve embodying my invention. Fig. 3 is a view of an angle-valve casing with the valve-trimming omitted. Figs. 4 and 5 are perspective views of details relating to the valve." Fig. 6 is a perspective view of the valve-seat removed from the valve-casing.
The valvecasing l is of any ordinary form, having the usual inlet and outlet openings, and a partition or diaphragm 2 to carry the valve-seat. This valve-seat is renewable, and it consists of aring-shaped piece 3, screwthreaded into the partition, as shown in Fig. 2. The upper edge of this ring forms the seat proper for the valve, and, as shown in Fig. 2, the valve 5 is adapted to rest upon this seat cast integral.
With the valve-casing and extending upwardly from .the screw-threaded seat in which the renewable ring is placed are a plurality of ribs 6. These are threaded to form continuations of the thread which receives the valve-seat ring, and at the top of the ribs the threading is continued within the neck 7 of the casing. By this means the valve-seat ring can be connected with the threads at the extreme upper end of the opening in the easing, and by the aid of a suitable implement the valve-seat can be quickly turned until it seats itself in the position shown in Fig. 2 ready to receive the valve.
I am aware that it is not new to have a seat for the valve-seat ring, which seat is screwthreaded; but in the old construction the thread does not continue on ribs all the way to the top of the valve-casing, and difficulty is experienced in replacing the valve-seat ring, owing to the fact that it must be introduced into the valve-casing at approximately the central portion thereof, where it is difficult to maintain accuratecontrol of the position of the valve-seat ring relatively to the screw-threads with which it must en gage.
By my invention the engagement of the threads of the valve-seat ring with the threads in the casing can take place at the top or neck of the casing, where full control of the position of the valve-seat may be maintained in relation to the threads of the casing.
In order to screw the valve-seat in or out, I provide it on its interior-with a plurality of lugs 8, with which a suitable wrench may be engaged to turn the said ring.
I do not limit myself to any particular form of valve-casing, such as shown in Fig. 2, with the diaphragm therein, as the invention may be applied to other forms, and Fig. 3 serves to illustrate this fact, said figure show ing an angle-valve casing in which the seat for the renewable valve-seat ring is formed in the body of the valve-casing instead of in a diaphragm therein. This form of valvecasing, like that above described, is provided with a series of vertical ribs having threads forming continuations of the threads of the seat for the valve-seat ring, the said threads being continued to the upper end of the valve-casing.
I claim as my invention- 1. In combination, a valve-casing having a threaded portion or seat to receive a renewable valve-seat ring, and having a plurality of ribs extending from said threaded portion, said ribs being threaded to form continuations of the threads of said portion, whereby the valve-seat ring may be connected with the threads at the upper ends of the said ribs, substantially as described.
2. In combination, a valve-casing having a threaded portion or seat to receive a valveseat ring, said casing having a plurality of ribs extending from the threaded portion and having their inner edges threaded to form continuations of the threads of said portion, the threads of the ribs being continued Within an opening in the casing, and the said valve-seat ring having means to receive a Wrench, substantially as described.
3. In combination, a valve-casing having a threaded portion or seat to receive a valveseat ring, said casing having a plurality of ribs, integral with the casing, extending from the threaded portion and having their inner edges threaded to form continuations of the threads of said portion, the threads of the ribs being continued into the neck of the casing, and the said valve-seat ring having means to receive a Wrench, substantially as described.
4. In combination, a valve-casing provided With a diaphragm having a threaded portion or seat therein to receive a valve-seat ring, said casing having a plurality of ribs, integral with the casing, extending from the threaded portion in the diaphragm and having their inner edges threaded to form continuations of the threads of'said portion, the threads of the ribs being continued into the neck of the casing, and the said valve-seat ring having means to receive a Wrench, substantially as described.
In testimony whereof I afiix my signature in presence of two Witnesses.
EDMUND H. LUNKEN.
