nurnovnmrim :N 'rmi venvr'rs or STEAM-Henri am The Schedule referred to in these Letten Patent and makins Part of the sama.
To whom it may concern: l
Be it known that I, ROBERT W. RUSSELL, lof the city, county, and State of -New York, have invented certain new and useful Improvements in lVorking the -DischargeValves of Steam-Fibre Guns; and I hereto which my invention relates, is fully described in the patent of A. S. Lyman, dated August 3, 1858, and in the patent of Horatio. Allen, assigner to American Fibre Company, dated March 2, 1869, and need not,
therefore, be here again described.
In the last-mentioned patent a method isspecified of bringing to rest the discharge-valve, when the same is unlocked and driven back bythe explosion, by means of an elastic, or yielding butier, which oers a yielding and gradually-increasing resistance to the movement of the valve. v
My invention has reference, mainly, to this method, and is designed to eect certain modifications in the construction and arrangement of both the bilder and thevalve, by which they may be the better adapted for use incertain cases, as, for instance, when a valve of great weight is employed, or when other circumstances .render the use of the ordinary valve and buffer impracticable, or inconvenient.
In lieujcf the special arrangement shown in the patent of Allen, above referred to, I attach to: the back of the discharge-valveA A of the gun, an arm, or pro- "jectin'g frame, B, upon the apex of which I prefer to mount a roller, a, which impinges upon the surface of a curved buffer. The roller is only employed to -.ie duce the friction, and may be dispensed with, if desircd.`
The buffer, in the present invention, is constructed .as follows:
A movable wood frame, O O, holds what may be termed the semicircular divided buffer D, tlie'at base of which rests on the bed of the machine. The buie'r, however, is` not ,a true semicircle, as it gains slightly between the points b c, on each side, so as to offer', between these points, a yielding -resistance to the roller a. That portion of the bu'er included between'the points b b is not intended to bear with 'anyforce against the roller,- andis shaped to this end, as represented in iig. 2, the red lines indicating the path of theiroller. The bu'er shouldbcsheathed with iron, which can be replaced from time to time, 'as it becomes worn. Between: the movable frame O and the buffer, are
inserted hails, or strips, f, of rubber, or other elastic material, which will allow either-part oi' the .budel to lyield as the roller passes over it. The buer is held np in position to receive the 'roller by wedges, d, driven between the movable frame O and the immovable frame, or posts E, by which said frame is-viipheld.- Instead of these wedges, screws, or other ordinary or smtable devices for the purpose, may beemployed.-
The roller attached to the arm of the discharge-valve, when the said valve is unlocked and driven backby the force of the explosion, ii'ins upon the curved surface of the buiier, and the movement of the valve is arrested before the roller reaches the termination of the serni- ,l
circle, under the gun; whereby the forceoftlie discharge is taken up easily and gradually by friction upon the semicircularelastic buffer, and much concussion of the grin is avoided, and strain upon the hinge ofthe valve diminished. A similar yielding curved buffer, or cushion, set over the gun, instead of being underit, to re ceive the discharge-valve, may be substituted for the above arrangement. i
A stiff spring may be `used instead of the India rubber ballsz or strips, in using thel buffer, to receive .the direct lblow of the discharge-valve. l
When the valve has terminated its niovernent,'and
larrives under the gnu, the wedges may be knocked away, or the other devices which hold the buffer .up in place may be drawn hack, so as to admit of the'two sections of the buffer moving apart, thus allowing the valve to be again swung up into place.
- The saine eiiect, viz, the diminution ofthe concussion, on the discharge of the gun, l.may also be obtained, by dispensing with the hinge-arrangement described in saidAllenspatennand'substituting-for the same a discharge-valve disconnected from the gun, or
a valve carried into, \cr against the mouth of the gun, and held there by means of a rod, mounted upon a piston, or other suitable device, and suddenly withl `drawn when it is desired to blow out the contents of A the gun.
In case a piston is employed, it should be placed in a small cylinder, into which steam, air, or water is forced, when the valve is to be brought up against the mouth of the gun. By affording escape for such arr,
l water, .or steam, at the proper moment, the valve will be liberated, and, consequently, forced .back by the pressure .of the steam' within the gun; or', the discharge-valve may be applied to the mouth.of the gun, and held in its place by latches, which are liberated by a lever, orA trigger, to eliect the discharge. 'Ihe valve is attached to a rod, or chain, fastened to a frame-work nea-r the gun, and, when discharged, is
caught by any suitable means, and brought back to the gun.
The same eil'ect mayalso be obtained as follows:
The gun is swuiig, or made movable, instead of,v
being fastened down firmly, and, when charged, is' moved by suitable machinery up against a valve, or
disk, bywhich contact the escape' of steam from the discharge-aperture of the gun is prevented, tlehvalvi en being held upin place by suitable means.
is desired to discharge the gun, it isf drawn back 'om.
the valve, or disk, which, at the same moment, is drawn away from the mouth' of the gun., v
Having now described my invention, and the manner in which the sameis,or may be carried into etiect,
What I claim, and desire to secure by Letters Patent, is l. The working of' the discharge-valve of the Esteem gun, used for isntegrating fibrous materiais, so as to prevent or diminish concussion, substantially in theV manner above desem'bed.
