UNITED STATES CH A RLES W. \VILLARD,
IMPRovEMl-:NT IN VALVE-GEAR FORSTEAMFHAMMERS. j
PATENT p OFFICE. 'l
OF GH ICAGO, ILLINOIS.
Specification forming part of Letters Patent No. 49,462, dated August 5,1S65.
To all 'whom it may concern.- l
Beit known that I, CHARLES W. WILLARD, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in SteamHammers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will ena ble others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in whichand by adjusting said dogs on the shanks ofV the T-shaped lever the stroke. of the hammer can be regulated.
A represents a hammer, which is hung on' trunnionsa, and acts on an anvil, B, in the ordinary manner. The hammer is tilted by the action ot' a piston which is litted in an ordinary steam-cyliuder, C, and the rod of which acts on the hammer.
The steam in the cylinder O is changed by the action of an oscillating valve which is fit-` ted into a valve-chest, E. The stem "of this valve carries a crank, 1), which connects by a rod, c, with a T-shaped lever, F, as shown in Fig. 1 ofthe drawings. Said lever has its fulcrum on a pivot, d, in a standard, Gr, and two of its Shanks carry dogs e, which are so constructed that they can be readily adjusted up or down. In order to effect this purpose the Shanks of the lever F are provided with a series of notches, f, and the dogs e are mounted in boxes c', which slide up and down on the shanks ot' the levers. `Springs e2 throw tho j f1 points ofthe dogs in contact. with theshanks ot' the lever, and causethe same to drop into the notchesj' and io retain the sldein the desired position. i
By a slight pressnie on the. tails of the dogs their points can beliherated from thenotches i fand' thewsiides can be adjusted up or down,
as may be desired. From the sidesof said slides project lips e3, and a tappet, g, secured to the cross-head h of the steam cylinder, by
coming in contact with said tappet, servesto tilt the T-shaped lever in one direction or in the other, and the valve is changed.
It is obvious that the stroke of the hammer, f I
which depends upon the motion allowed to tllc steam-piston, depends entirely upon the position of the dogs e. It these dogs-are moved closer together the stroke ot' the hammer is shortened. Ifthedogsaremoved'fartlierapart i l thestroke of the hammer is lengthened. r
It will also be easily understood that by thesemeans the blow ofthe hammer can be partially checked if the lower dog is so placed that the piston is not allowed to descend far enough to allow the hammer to strike with its full force upon the anvil. The dogs can be changed instantaneously, and the operator `has thus coui plete control over the motion of the hammer and the force ofits blows.
I claim as new and desire to secure by Letters Patent- The T-shapcd lever F and adjustable dogs e, in combination with the steam-valve, cylin` der, and hammer, all constructed and operating substantially in the manner and for the purpose set forth.
culas. fw. WILLARD.
