IMPROVED TRIP-HAMMER. i

TOvLL WI-IOM IT MAY CONCERN' Be it `known that I, CHARLES VOGEL, lof the city, county, and State of New York, have-invented new and useful Improvements in ,Trip-Hammersg and I do hereby declare that the following is a full and exact description thereof, which will enable thoseskillcd in the art to make and use the same, reference being had tc the accompanying drawings, and the letters of reference marked thereon. 4 y

The present invention consists, rst, inta novel connectionbetween the shank or stem ofthe hammer-head and thebeam, through which the hammer-head is trippedi second, in soioonstructing the beam carrying the hammer-stein or shank that it can be adjusted for raisingthe hammer-head to a greater or lesser height; third, in a n ovel combination andvadaptation of springs for imparting additional force and strength to the blow oi' the hammer, their combination and'arrangementbeing such as to be susceptible ofadjustment for a'blow of greater or lesserdegree of force and strength; fourth, in a novel arrangement of parte for arresting the motion of'the hammer without requiring the driving-mechanism to be stopped, the arrangement being such as to' he selfoperating, when set free, and to arrest the hammer, when at or near the end of itsv upward stroke orl movement, and 'there hold it, leaving the anvil exposed fifth, in an arrangement of parts upon the driving-shaft of the trip-hammer, on which they are hung, to swing about and over its driving-pulley, in combination with a treadle, or other suitable operating-lever, for the purpose of en'ablingthe driving-belt to bemore or less tightened about the driving-pulley, as may be desired or found necessary in the running of the hammer. l In the accompanying plate of drawings, my improvements in trip-hammers are illustrated- Figure 1 being a partial side elevation or view and vertical section of a trip-hammer constructed according thereto, l

Figure 2 a. plan or top view, and

c Figure 3 a detail View. y A, inthe drawings,'represents a framework, carrying the several parts, to be hereinafter described, composing a. trip-hammer, arranged to embrace the several features of `thepresent improvements.

This framework A consists of two similar-shaped upright frames,B, made ofthe general outline and shape shown in the drawings, and braced inposition,` at the proper distance apart, by brace-rods C, at suitable'points,A

and at Vtheir lower` ends, D, properly constructedfor being bolted or otherwise fastened to a door, or other fixed surface. v 'i t These frames B, at the outer ends to their lower extension-pieces E, are joined and fastened to a common block, F, that, upon itsupper surface, G, is adapted to receive the anvil-block H, on which the hammer of the machine is to drop and act. Over this anvil-block' H, but at a proper distance above, the upper arms I to the side-frames B extend, and are there joined together 4,by a common cross-head, J', suitably constructed for ln stem or shaft, Kto move in a vertical plane, which stem, at its lower end, L, carries and has properly fixed to itthe hammer-head M. A

To this hammerstem K the cross-head J forms one guide, in its upward and downward movement, but to more perfectly and steadily guide it, another guide, N, is provided, that, by-upright's O, is supported in position directly above the said cross-head J'. n j

P, a cross-arm `to upper end of hammer-stem K, above its upper guide To the outer ends of this cross arm P, and upon each side of the hammer-stem K, is hung theupper end of similar connecting or Pitman-rods Q, that, being extended down along and upon the sides of the hammer-stem, are, at their lower ends, hung to the outer ends of the angular arms It, at the front end to the beam S, ixed toaJ shaft, T, arranged to turn in bearings of the side-frarnes B, across from one to the other of which it extends on a horizontal plane. This beam S is extended to the Vrear of its shaft T, and at such end is provided with a. block, U, having slots V, through which the screw-bolts W pass, that are used for fastening such block to the beam. By means of these slots V, the blockfU is' susceptible of adjustment upon the beam S, in the direction of its length, and thus the end X to auch block, made to project more or less to the rear of the. shaftl T, for being acted upon by the tripcam or arm Y, fixed to the Vdriving-shaft Thisdrivingshaft Z is arranged to turn in bearings of the sideframes B, across from one to the other of which it extends ina horizontal plane, and,at one end, has a balancewheel, A, and a ange-pulley', B2, around which a belt from the driving-power is passed.

From the above description of the arrangement of parts, it is plainly shown that, by the `turning of the driving-shaft Z in the proper direction, the hammer will be lifted or raisedup, through the action of the cam or arm Y of such shaft, upon the beam to which the hammer is connected, until, by the continued turning of 1,

the shaft Z, its cam has passed by the said beam, when the hammer is then free to falll,fr;m its own weight and gravity, te the anvil-block, and upon whatever substance may be there placed for being hammered by it; land that, also, as the block td the beam carrying the'hammer is susceptible of adjustment upon the said beam, the height to which thephammer is toA be raised may be varied or m-ade more or less within certainlimits by simply projecting such block either more or l'ess into'the plane of rotation to the tripping-cam or arm of the driving-shaft.

Around the rocker-shaft, to which the beam is secured, carrying the hammer, and upon each side of such beam, is a similar-coiled or spiral spring, D2, .that are both exterided by ltheir end the nearer to the beam, toward the plane 'of movement of the hammer, resting upon the cross-arm E2, to a bolt,1i'2, secured in the beam S by a screw-nut, G2, and by their end the farther from the-beam, to and upon the grooved rests H2, fixed to a common horizontal transverse shaft, I, of the side-frames B.

This shaft I2 is`arranged to turn in the frames B, and for turning it,a hand-wheel, J2, is provided, working through .a tubular shaft, K2, to which it is secured, that has a worm-gear, L2, working into a pinion, M2, of the said. shaft I2. The tubular shaft K2 is hung in suitable bearings of the framework A.

Bylthe above-described arrangement of springs D2, which rest upon the beam carrying the hammer,and upon the rests of-the shaft 12,'it is plainly manifest that, in the raising of the hammer, they will-be, to a greater or lesser extent, the more tightly coiled thereby, according to the relative positions of 'the rests with regard to y lthe movement of the hammer, and thus, when the hammer is left free to fall, in uncoiling, made to'rimpart a corresponding amount of additional forceor strength to itsblow.

I To increase or decrease this action of the springs, their rests are susceptible of adjustment, those upon the .beam by simply raising or lowering thc cross-arm, through the turningo'f the screw-nut, and the others, that are upon the shaft 1 2, by turning such shaft in the proper direction to either throw them up or down, as the case mayrequire., i

A4, a pulley, arranged to 'slide on the driving-shaft, between its cam-trip and one of the side-frames B; This pulley A4 is e'qua-lporlnearly so,.in diameter to that of the largest circle described by the said cam, as the driving-shaft revolves, so that, if placed in position upon the tripping-end of the hammer-beam, to bear against twhen the hammer is up, it will not allow the hammer to fall to the anvil, or, in other words, it will prevent all action ofthe trip-cam upon the hammer-beam. f l

This pulley A4 is provided with a collar, B'upon its outside face. `This collar B'4 is Agrooved around its periphery, and in such groove C4 the outer ends to a forked-shaped arm, D4, are located, which arm B4, by its common shank E4, is fastened to one end of'a rod, F4, that is extended through the tubular shaft K2, herein-I 'before referred to, and at the front end to such tube, provided with a handle, G4, for convenience in turning and thus, by means of such turning, slide the said pulley A4 either toward o'r away from the plane ofaction of the hammer-beam, as maybe thought necessary.

Y To this handle Gr* a spring-pawl,H4, is hung, to engage with the notch I4 of the arm J4, and to thus hold the pulley out of the plane of action of the hammer-beam, when,'as such pawl is released, a spiralyspring, K4,V is properly-arranged to slide the pulley intov the plane of movement to the hammer-beam the instant it is brought to the proper point bythe action of the trip-cam, toy allow it to pass by.

From the description above of the arrangement and operation of parts4 for stopping the movement4 of the hammer-beam, it islplain to beseen that it is not necessary'to arrest the driving-mechanism, nor to throw the driving-shaft to the trip-hammer out of connection therewith, and that, furthermore, they are self-operating, when set free for action, and are so'arranged as to hold the hammer 'at or near its highest point of elevation,

thus leaving the anvil-block free to the workman for arranging the work thereon, or for any other purpose.

A5, a frame, hung upon the driving-shaft, so as' to turn thereon, and' to swing over its driving-belt pulley. This frame carries a roller, B", at one end, for the action upon the driving-belt, as the frame is swung up into a. vertical position, to tighten it about the pulley, either more or less, according as it is made to approach either more or less near to a. vertical position.

C5, a rod, connecting frames A5 with-one end, to a treadle-frame, B5, hung upon a fulcrum, E5, ofthe sideiramesB. This treadle-frame extends around the front end ofthe framework, and at such portion is suitably 4ilattened for thereception of the prop to depress it to a greater or lesser extent, a stop, E5, being hung'ro the anvil:block ho1der,.in position for being swung to hold the treadle down, when desired.

When the prop or Steiner both, are released from the treadle, the belt-tightener, which is attached, resumes its horizontal-position, in doing which, springs K5 are provided to assist and facilitate the same.

Having thus described my invention, I cla-im as new, and desire to secure by Letters Patent- Y I. The bars er rods Q, secured lto they cross-head P of the hammer-stem K, when said rods are attached'to the angular arms R, upon the front end of the beam S, as herein shown and described.

2. The block U, provided with the cam-shaped end X, when 'adjusted upon the beam S, by means of the slots V and screw-bolts W,`as herein described, for the purpose specified. l

3. The arrangement of the sliding vpulley A, orits equivalent, with the block and with the operatingbeam of the'hammer, substantially as described, for the purpose specified.

4. The tightener-frame A5, bearing in one end the driving-pulley7 B5, arranged'with the connecting-'rods C5, curved tieadle D5, and spring K5, as herein described,A for the purpose specified.

The above specification of my invention signed by me, this 20th day of August, 1867.
