ROBERT MORRISON, OF NEWCASTLE-UPON-TYNE, GREAT BRITAIN IMPROVEMENT IN VALVES FOR STEAMi-HAMMERS.
Specification forming part of Letters Patent No. 38,976, dated June 23, 1 863; patented in England,
December 16, 1859. v
To all whom it may concern:
Be it known that 1,1to13nnr Monnlsomotthe town and county of Newcastle-upon-Tyne,
in the Kingdom of Great Britain, .have invented a new and useful improvement in Valves for Double and Single Acting Steam- Hammers, and for which Letters Patent were granted me in the Kingdom of Great Britain, dated 16th of December, 1859;, and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawing, and to the figures and letters of reference marked thereon.
The object of my invention is to increase the efficiency of steam-hammers by admitting the steam below or above the piston at will, so that the hammer may be worked single-acting or be instantly changed to double-acting whenever it may be desired to increase the weight or rapidity of its blows.
I The nature of: my invention consists in the employment of a valve so arranged with reference to the ports that it may place both ends ofthe cylinder in connection with each other at the same time, this valve to be also so arranged that whenever the steam shall be admitted on either side of the piston the communication between this side andthe exh aust port shall be closed.
A reference to the drawing making part of this specification will more fully explain the nature of my invention.
' Figure. 1 represents a cylindrical piston-equilibrium valve, with its steam-chest, which is to be attached to the steam-cylinder in the place used for that purpose on my drawing of improvements imvalve-g earin g for double and single actingsteam-hammers, filed September A is the steam-pipe, the steam passing through the valve into the space E. B is the exhaust-pipe. O is the. passage or port lead ing to the top of the hammer-cylinder, and D that leadin g to the bottom of the cylinder.
the air or steam to escape as it is forced upward by the ascending piston. On bringing the valve down to the position as shown in the drawing, 2 will still remain nearly open and v 3 entirely so, permitting the weight of the hammer to expel the steam which had raised it, while the space in the upper part of the cylinder left by the descending piston is filled through port 2, left open for that purpose. If, however, in place of stopping the equilibriumvalve so as to leave port 2 open, it should have its motion continued so as to close this port and admit the pressure of the steam upon the upper part of the piston, the descent of the hammer would be greatly accelerated.
It is evident that the same result could be attained with a great variety of valves,'and that four ports are not necessary to accomplish it, so that I do not limit my claim to any particular. form of valve, or to any number of steam and exhaust openings; but
WhatI do claim as new, and desire to secure by Letters Patent, is-
The use of a valve in steam-hammers, when so arranged. with reference to the ports thatbo'th ends of the steam-cylinder can be placed in communication with each other at the same time, communication with the'b'oiler being then out 011', the same valve being also so arranged that whenever steam'shall be admitted'to one end of the cylinder communication between.
that end and the other shall be out off, substantially as described, and for the .purpose specified.
