2U communicating with the interior of the piston rod I5. Said sleeve is fashioned on the outer periphery thereof with a circumferentially extending shoulder 2I engaging the upper edge of the rod I5 whereby the lower portion of said sleeve is maintained within the bore of the rod I5. The upper end of the sleeve is tapered as at 22 for engagement with the ceiling I1. The lower portion of the sleeve subjacent the shoulder 2I is formed with a slot 23 communicating with the aperture 20 and which accommodates therein the inner end of a valve 24 threadedly carried by the rod I5 adjacent the upper end thereof. The outer end of the valve is threaded to receive an air connection whereby air may be introduced into the cylinder below the piston I4 through the bore of the rod I5 and aperture 20 The upper section of the cylinder 8 is provided with an air vent 25 to prevent compression within the cylinder above the piston I4.
Attention is directed to the fact that the cylinder is of a greater diameter than the casing, and likewise the head I 0 is of a greater diameter than the diameter of the cylinder. Furthermore, the outside diameter of the rod I5 is of such a diameter relative to the inside diameter of the casing as to provide an operating fit.
In use, dueV to the greatly increased diameter of the cylinder of the casing 5, the head engages an area of a floor of a greater diameter than would be the case if the cylinder was of a like diameter with the casing, thereby counteracting the torque transmitted to the casing from the arm and maintaining the mounting in xed position between the ceiling and floor of the drift. In operation, vair introduced into the cylinder, through the medium of the bore in the rod I5, aperture 20 in` the sleeve and valve 24, causes relative movement of the piston and cylinder and eiects a clamping of the mounting between the ceiling and bottom of the drift.
In instances where it is desired to use the mounting in wide drifts, an auxiliary sleeve 26 is employed and inserted over thermember I6 and a supplemental member 21 inserted in said sleeve to increase the length of the member I6, as clearly illustrated in Figure 3 of the drawing.
From the foregoing it will be apparent that the enlarged cylinder permits a greater force to be applied to the piston as well as providing a larger base or supporting member. For example, a 3" piston exerts 720 pounds pressure on the piston rod, a 5 piston 1960 pounds, a 6 piston 2800 pounds, an 8'.' piston 4400 pounds when supplied with a liquid under pounds pressure due to the enlarged area of the face of the piston. Tests seem to prove that a 6" piston member is required to `successfully meet and overcome the torque and twisting eiTect based on the supporting column by the conventional rock drill machines now in use, while being used out at the end of the supporting arm and opposite the supporting column. This being the case, the fact'is obvious that a column with an internal diameter of 6 inches wouldI be too heavy and large to be of use in the mining industry. The conventional size drill support has an outside diameter of approximately 31/2". Thus by enlarging the cylinder section or member of the column I am enabled to obtain my new and advantageous result.
What I claim is: v
1. A drill mounting comprising a piston rod casing, a drill supporting arm secured on said casing and adapted to adjustably accommodate a drill thereon, a cylinder secured to one end of said casing and provided with a head for engagement with a wall of a drift, a piston rod operable in said casing, a piston operable in said cylinder and connected about one end of said rod, and means carried by the other end of said rod for engaging the opposite wall of the drift, said cylinder of a larger diameter than said casing whereby as a consequence said head engages an area of said first mentioned wall of a greater diameter than said casing to counteract torque and twist transmitted to said casing from said arm to maintain the mounting in fixed position between said walls.
2. A drill mounting comprising a piston rod casing, a drill supporting arm secured on said casing and adapted to adjustably accommodate a drilll thereon, a cylinder secured to one end of said casing and provided with a head for engagement with a wall of a drift, a piston rod operable in said casing, a piston operable in said cylinder and connected about one end of said rod,
