UNITED STATES CHARLES A. \VELLINGTON, OF LEXIEGTON, MASSACHUSETTS.
MACHINE FOR CRACKING 0R SPLITTI NG MARBLE OR OTHER STONE.
SPECIFICATION forming part of Letters Patent No. 254,415, dated February 28, 1882.
' Application filed December 19, 1881.
To all "whom it may concern:
Be it known that I, CHARLES A. WELLING- TON, of Lexington, in the county of Middlesex and State of Massachusetts, a citizen of the United States, haveinvented a certain new and useful Improvement in Machines for Cracking or Splitting Marble and other Stone, Pottery, and other like substance, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawing, forming a part of this specification, in explaining its nature, in which Figure l is a side elevation of a machine containing my invention, with a. part of the toolsupporting rod broken out to show the method of fastening the tool in place. Fig. 2 is afront elevation of the machine. Fig. 3 is a side elevation of the machine adapted to be operated by a foot-treadle.
The object of this invention is to provide means for cracking, fracturing, or splitting marbles and other stones and other material into small pieces of any desired shape.
The invention comprises a stationary wedge- -shaped tool, suitably supported, in a vertical position, and a movable wedge-shaped tool, preferably of the same size as the under tool, but reversedin position in relation thereto, and adapted to be recipro'cated to and from the firstnamed tool in any desirable way.
In the drawings, A represents the frame of the machine. B is the lower wedge-shaped tool; B, the upper wedge-shaped tool. The lower one has a stud or spindle, b, which enters the hole bin the frame, and can readily be removed therefrom. Theupper tool, B, is provided with the spindle b which enters the hole in the end of the bar or rod 12 and is fastened thereto by the screw 11. This bar or rod is adapted to be reciprocated in the head C against the stress of the spring by hand, foot, or motive power,
and I have represented it as being adapted to be recprocated by hand and by foot. In the former instance the rod is surrounded by the coiled spring D, between the head 11 of the rod and the upper part of the frame of the machine, as represented. In the latter instance I show the long spring-arm E, which is fastened to the frame of the machine at one end, and at the other end is attached by a screw or stud to the head of the rod. The rod is lifted against the stress of this spring by means of the treadle F, connecting-rod f, and lever f, whichis pivoted at) to the frame of the machine.
The end f of the lever, when the tool and its PATENT OFFICE.
(No model.)
. supporting-rod are in their normal position, bears the relation to the projection or latch f upon the rod as shown in Fig. 3. Upon depressing the treadle the rod is lifted until the lever f clears the latch, and the force of the flat-spring throws down the rod and tool. It is essential, however, that the spring should not act to throw the tool downward so that it shall touch the stationary tool with its full force; but, to the contrary, it should act to restrain the movement of the tool ater it has reached a certain position, and it should then act to. return it to its normal or original position, asshown in Fig.3, while the trvadle-spring f lifts the treadle and causes the lover f to be returned to its original position-that is, the'upper tool must not be forced down so hard as to come in contact with the lower tool, at any rate with anydegree of force-and after the tripping ofthe lever the parts should autoin atically assume their original positions, in order that the device can be again operated without delay.
In operation the marble, stone, or other material to be split or cracked is paced be tween the two wedges, and by the descent of the upper one a piece of any desired shape may be cracked or split therefrom.
Of course it is not necessary that the upper tool be a reciprocating one, although it is desirable, as the lower one can be reciprocated and the upper one be stationary, and itis pos sible to get good results by reciprocating both tools; but the const ruction which 1 preler is that which is above described.
Having thus fully described my inwntion, I claim and desire to secure by Letters Patent of the United States 1. The combination, in a machine for splitting or cracking stone, marble, 85c of the [001 B, its supporting-rod, and actuating-swing with the tool or supportB, all substantially as and for the purposes'described.
2. The combination of the tool B, its supporting-rod and actuating-spring, the treadle F and connecting mechanism, substantially as specified, and the lower tool or support B, all arranged so that the upper tool may be reciprocated by foot, all substantially as described.
CHARLES 'A. WELLINGTON.
