Description
UNITED STATES PATENT EEICE.
C. L. FRINK, OF ROGKVILLE, CONNGTIGT.
Specification forming part of Letters Patent No. 55,639. dated June 19, 1866.
To all whom 'it may concern.-
Be it known that I, G. L. FRINK, of Rockville, in the county of Tolland and State of Connecticut, have invented a new and useful Improvement in Safety-Valves 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l represents a sectional side elevation of this invention. Fig. 2 is a transverse section ot' the lever, showing its connection with the valve-stem.
Similar letters oi" reference indicate corresponding parts.
This invention consists in the arrangement of' a swinging supporter, in combination with the stem and lever ot' a safety-valve, in such a manner that said supporter will accommodate itself' to the position of the lever and the lateral strain 011 the valve-stem will be diminished or avoided.
It consists, further, in making the standard which supports the fulcrum of the lever of a safety-valve adjustable in such a manner that the same'can be readily accommodated to the length ofthe valve-stem and the lever can be easily brought in a horizontal position.
It consists, tnally, in the arrangement of a central screw and cla1npingplate,in combination with the valve and valve-stein, in such a manner that the face ofthe said valve can be readily packed, and the packing can be renewed Whenever it should become desirable.
A represents the box or shell of my safety- Valve B, said valve being secured to the bottom end of a stem, C, and made to close down upon a seat, a.
To the top of the stem C is attached a hinged support, as D, which is composed of two crossbars, b b', and two straps, c. The top crossbar, b, is firmly secured to the valve-stem, but the lower cross-bar, b', tits loosely on the same and rests in the supporting-straps c, which are suspended from the endsA of the top cross-bar, as clearly shown in the drawings.
The lever E, which is loaded with a Weight, F, is split so that it straddles the top end of the valve-stem and rests upon the lowest crossfbar, b', of the supporter D. This cross-bar has a swinging motion in the direction ot' the lever, and if the valve rises, or if the lever should not be in perfectly horizontal position, said supporter accommodates itself to the position ofthe lever, and the lateral strain on the valvestem is diminished or avoided.
The lever E has its fulcrum in a standard, G, which rises from the top plate oi' the boiler. This standard I have made adjustable by a screw-thread, so that it can be easily lengthened or shortened, and that the lever E can be brought in a horizontal position.
In practice I, propose to make this standard out of two parts, which will be connected by a left and right hand thread, so that the length thereof can be adjusted with ease and convenience, and without removing the fulcrum-pin ot` the lever.
The face of the valve is packed by means of a piece, d, of india-rubber or other suitable material, which is held in place by a plate, e, and screwf. By removing this screw thepacking can be readily taken out and renewed whenever it shall become necessary.
What I claim as new, and desire to secure by Letters Patent, is
l. The hinged supporter D, in combination with the valve-stem C and lever F of a safety valvesubsta1'1tially as and for the purpose described.
2. The central screw, f, and clam ping-plate e, in combination with thgbpackingpiece cl and valve B, constructed and operating substantial as and for the purpose described.
G. L. FRINK.
