UNITED STATES PATENT OEETcE.
DANIEL SEXTON, OF SAN GABRIEL, CALIFORNIA.
IMPROVEMENT IN ROT-ARY VALVES.
Specication forming part of Letters Patent No. 58,307, dated September 25, 1866..
To all whom 'it may concern.-
Beit known that LDANIEL SEXTON, of San Gabriel, in the county of Los Angeles and State of California, have invented a new and Improved Steam-Valve; and I do hereby declare that the following is afull, clear, and exact description thereof,which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 represents a longitudinal central section of this invention. Figure 2 is a transverse section ofthe same, the line a; m, Fig. 1, indicating the plane of section. Fig. 3 is an end view of the same. Fig. 4 is a transverse section of the same, taken in the plane indicated by the lines y y, Fig. l.
Similar letters of reference indicate like parts.
This inventioneonsists of a thimble-shaped valve provided with a transverse partition, and fitted on a central spindle, which is held in position by a suitable temper-screw, in co|nbination with a cylindrical valve-chamber, and with suitable steam and exhaust ports situated on opposite sides of the transverse partition, in such a manner that by said partition the pressure is separated from the exhaust end of the valve and thrown entirely on a center or pivot7 and a valve is obtained which works free and easy, and the friction of which can be regulated from the outside.
A represents a cylindrical valve-chest, into which is iitted the valve B, which is mounted on a stem, C, and to which an oscillating motion is imparted by the lever D. Said valve e is provided with a transverse partition, E,
While it exhausts through the opening b on the opposite side of said partition.
The valve B is provided with two ports, c c', on the steam side of the partition E, and with one port, d, on the exhaust side thereof; and by giving an oscillating motion to said valve the ports c c are alternately brought over the ports e c' in the valve-chamber, and steam is adinitted first to one and then to the opposite end of the cylinder, while at the same time the exhaust-'port d coincides with one of the ex haust-ports f orf in the chamber, so that the steam from the exhaust end of the cylinder is free to escape. By this arrangement a valve is obtained the wearing pressure of which is wholly endwise on a pivot which is regulated by the temper-screw G; and by these means the friction of the valve is reduced to a minimum, and it can be easily controlled bythe temper-screw. This temper-screw rests in a bridge which is rmly secured to the valvep chest, so that it cannot be torn loose from its fastenin gs, and a valve is obtained which cannot fail to work correct, and whichcan be readily reversed and also lubricated in the usual manner. The receiving and discharge ports can be placed at any desired point in their respective ends of thek valve-chest, and in practice the valve and valve-chest will be made slightly tapering, so that it will wear tight.

. What I claim as new, and desire tosecure,
DANIEL SEXTON.
