CLAMPING MECH-AINISM FORSTEAM ROCK-DRILLS.
. SPECIFICATION forming part of Letters Patent No. 264,524, dated September 19, 18.82. Application tiled July 29, 1882. (No model.)
.To all whom it may concern:
Be it known that I, JOSEPH C. GITHENs, of the city and State of New York, have invented an Improvement in Clamping Mechanisms for Steam Rock-Drills, of which the following is a specification.
Itis the object of my invention to simplify the construction ot' the clamping mechanism by which the carriages ot rock-drills are adjustably secured to the tripod or other object which supportsthem. The requirements ot' mechanism of this character are that the drillcylinder carriage, when the clamps are loosened, shall have the capacity of oscillation upon two axes which are 'perpendicular with relation to each other.
The accompanying drawings, illustrating a clamping device embodying my invention, are as follows: Figure l is an isometrical perspective. central portion of a drill -cylinder carriage and a transverse section of the clamping-jaws, showing the bolts by which the clamping-jaws i are tightened upon the horizontal shaft of the tripod, and the transverse clamping-bolt by which the daring trunnion ot` thev drill-'cylinder carriageis tightened upon the seat afforded for it by the disk formed upon the top of the upper clamping-jaw.
The drawings represent a two-part clamp, composed of the upper jaw, A, and the lower jaw, B, which are adapted to embrace the bar or shaft upon which the structure is mounted. The tightening of the jaws A and B is provided for by means preferably of the bolts C c, which are inserted respectively through holes bored through the lugs a, c b b', formed upon the sides ot' the jaws A and B, respectively. The upper portions, C c', ofthe holes through the upper jaw, A, are enlarged to adlmit the heads C2 c2 ot' the bolts, respectively The grip ofthe jaws A and B upon the object which they embrace is adjusted in the usual manner by means ofthe nuts G3 c3, applied to the ends of the bolts C c, respectively.
It will of course be understood that tapbolts may, if desired, be substituted for the nut-bolts C and c, in which case the holes in the jaw A for the reception of the tap-bolts 5o will not require to be carried entirely through Fig. 2 is a sideelevation of the the jaw A, as is necessary when nut-bolts are employed, as shown.
The upper part of the jawA is formed into the disk A', which affords the 'bearing for the darin g end ofthe drill-cylindercarriage trun- .nion D, theedge D' of which is inwardly beveled, as shown. Nearly one-half the circumference of the disk A is provided with the upwardly-prjecting iange A2, the concave face of which is undercut to conform to the shape of the beveled edge D' of the truuuion.
The auge A2 constitutes the fixed jaw, against which the trunnon is adjust-ably clamped by means of the clamping-bolt E, inserted transversely through `the upper jaw, A, a short distance below the surface of the 'disk A.
The head E of the clamping-bolt projects l upward above the top of the disk A', and its inner edge is curved concentrically with the jaw A2, and undercut to fit the beveled edge of the truuuion.
The end of the bolt E projects through the Vboss A3, formed upon the side of the jaw A, and the face ot' 'this boss forms the bearing for the clamping-nut E2, applied to theprojecting end of the bolt E.
Itwill be seen that my clalnpiugmechanism, which is composed merely of the two principal pieces A and B and of the three bolts, O, c, and E, with their corresponding nuts,is simple and substantial in construction, and is capable of easy adjustment upon the rod orcolumn which supports the drill-carriage.
ln applying my invention to a tripod, the Haring trunnion-of the carriage is 'provided with a seat formed upon the tripod-head and having the undercut flange A2 upon one side,
IOO
vided with the upwardly-projecting head E', Bange A2 and the clamping-bolt E, having; at and withihe clamping-nut E2; and, secondly, one 0nd the undercut upwardly-projecng Io ot' the lowerjziw, B, and the bolts fortightenhead E and at the other end the nut E2, as ing the jaws A and B upon a bar or shaft emand for the purpose set forth.
braced by them. JOSEPH O. GITHENS.
