TRIP-HAMMER.
SPECIFICATION forming part of Letters Patent No. 243,986, dated July 5, 1881. Application filed April 1, 1881. (No model.)
To all whom it may concern:
Be it known that I, SOLOMON SHETTER, of New Cumberland, in the county of Hancock and State of West Virginia, have invented a new Improvement in Trip-Hammers, of which the following is a full, clear, and exact description.
My invention relates to a means for regulating the force of the blow given by the hammer, and for entirely stopping the motion of the hammer with ease and celerity without stopping the engine or other motive power-by which the hammer is driven, and without the necessity for shifting a belt from a fast to a loose pulley.
Theinvention consists, essentially,in a novel construction, arrangement, and combination, with the hammer, of an inclined plane carried by the hammer-stale, a cam-wheel adapted to engage with said inclined plane, and devices connected with said parts, whereby provision is made for limiting the rise of the hammer and for entirely stopping its motion, as hereinafter more particularly described.
The accompanying drawing represents a perspective view of a machine embodying my improvements.
A represents the hammer, provided with a stale, a, which is pivoted between two posts, G G, of the frame of the machine by a pin, bolt, or screw, g, and is guided in its rise and fall by the posts H H. The hammer-stale a is provided with an inclined plane, B, on its lower side for engagement with a cam or wiper wheel, O, which does not touch the stale at all, even when in its lowest position. The cam or wiper wheel 0 is carried by a shaft, 0, which is angular, or of any shape other than cylindrical, except at the journals, and it turns with said shaft, but is free to slide laterally thereon.
At one side of the wiper-Wheel is a hub, D, provided with a peripherical groove, d, in which works the forked end of a lever, E, which is pivoted to the frame F by a pin, 0, and which is the means provided for moving the camwheel and hub on the shaft 0 under and out from under or into and out of engagement with the inclined plane B on the hammer-stale a.
To the frame F is attached a plate provided with notches f for the purpose of retaining the lever, and consequently the wiper-wheel, in any desired position. i
K K are stops for limiting the motion of the lever. J is a spring, attached to the upper portion of the frame of the machine, for giving additional force to the stroke of the hammer.
When the hammer is to be set in motion the long arm of the lever E is moved to the left. This moves the hub D and cam-Wheel O on the shaft 0 under the inclined plane B. As soon as the wheel is moved far enough for the cams to engage with the inclined plane it will alternately raise the hammer and allow-it to drop.,
The drop of the hammer is aided and the force of the blow increased by the spring J. The nearer to the right-hand end of the inclined plane the cam-wheel is moved the higher will the hammer be raised, and with the greater foreewillitdescend. When thedesiredamount of force is obtained the lever E is engaged with one of the notchesf, so as to hold it in'place.
When it is desired to stop the motion of the hammer the cam-wheel is moved to the left by moving the long arm of the lever to'the right until the cam-wheel is out of engagement with the inclined plane.
Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-
The combination, with the hammer A, having stale a, with the incline B, of the posts G G H H, the superposed spring J, and the shaft a, lying in the vertical plane of the axis of said hammer-stale and carrying the slide-cam O, as shown and described.
SOLOMON SHETTER.
