UNITED STATES PATENT OFFICE.
WALTER ARNOLD, OF SAUK RAPIDS, MINNESOTA.
ROCK-DRILLING MACHINE.
SPECIFICATION forming part of Letters Patent No. 458,612, dated September 1, 1891.
Application filed May 18, 1891. Serial No. 393,106. (No model.)
To all whom it may concern:
Be it known that I, \VALTER ARNOLD, a citizen of the United States, residing at Sank Rapids, in the county of Benton, State of Minnesota, have invented certain new and useful Improvements in Rock-Drilling Machines, of which the following is a specification, reference being had therein to the accompanyin g drawings.
My invention relates to improvements in the frame of rock-drilling or rock-channeling machines.
The object of my invention is to construct a frame for carrying and operating drilling or channeling tools in a workshop, said frame being so constructed as to permit the passage of a stone-carrying truck therethrough. It is provided with a horizontal quarry-bar and peculiar means for retaining said bar adj ustably connected to the frame, as hereinafter described.
In the accompanying drawings, Figure l is a front elevation of a rock-drilling machine constructed in accordance with my invention. Fig. 2 is a transverse vertical section through the quarry-bar and showing a portion of the posts constituting one end of the frame and the means for retaining the quarry-bar adjustably retained and clamped to said posts. Fig. 3 is a transverse horizontal section through the posts, showing a portion of the quarry-bar and its retaining device clamped to said posts.
In said drawings, A represents a pair of posts, and A a similar pair of posts. Said pairs of posts are connected together at the bottom by a sill 13, upon which truck-rails b are shown, and at the top by two beams B At a suitable distance under said beams the quarry-bar O is adjustably retained and carries the drill-holder and operating mechanism C which may be of any of the wellknown kinds and do not constitute any part of the present invention. The ends of the quarry-bar G are journaled into boxes or blocks D, preferably in the form of a Maltese cross having two of its arms received in vertical grooves formed on the inner sides of the posts A and A The blocks D have a central vertical perforation which is screw-tapped to receive screws E, that can be rotated to raise or lower said blocks and the quarry-bar carried thereby. Theupper portions of the screws are received in bearings 72 secured to the beams B and the lower ends of said screws are received in bearings a, resting on blocks a located between the posts of each pair alongside their lower portion.
To rotate the screws, each one carries on its upper end a bevel-pinion F, with which bcvelpinions G are arranged to mesh. Said pinions G are mounted upon a shaft G retained parallel with the beams B by bearings 9 upon said beams. To permit the screws E to be rotated by a person standing on the floor supporting the machine, the shaft G is also provided at one end with abevel-pinion G and with the latter a bevel-pinion H is made to mesh. Said pinion II is mounted on the upper end of a vertical shaft H having its upper end guided in a bearing mounted upon the beams B and its lower portion guided in a bearing h, secured to the sides of the posts A To the lower end of the shaft H is secured a bevel-pinion 1 1 that is made to mesh with a bevel-pinion I upon a short horizontal shaft 1 mounted in bearings t' and i and said shaft carries a hand-crank 1 by which it can be rotated.
The drill-holder O is suitably secured to the quarry-bar C, and the latter can be rotated on its journals; but to retain it at any point of its rotation, with the drill pointing in any desired position, the bar 0 has at one end a cylindrical portion that is provided with a series of radial holes 76, within the uppermost one of which a vertical finger m is made to enter. Said finger is secured to a yoke M, that extends across the face of both posts A and has hooked ends to engage with flat metal bars a vertically secured to the sides of the posts A To clamp the yoke to the posts, one of the hooked ends has two ribs m projecting from its face, and through said ribs is passed a pivot-pin, that passes also ec centrically through the head of a handle M The hooked end of the yoke has a slot between the two ribs m so that the curved surface of the eccentric head of the handle M can enter said slot and bear upon one of the bars a with more or less frictional pressure, according to the angle at which the handle is set.
Having now fully described my invention,
I claim The combination of the two pairs of posts of a rock-drilling" machine, the screw-tapped 5 blockstherein, and the screwspassing through them with the quarry-bar 0, having radial perforations in one end thereof, the yoke M, embracing one of the pairs of posts and having' a finger m entering one of said radial per- 10 forations and one of the hooked ends provided withparallel ribs, and a handle eccentrically pivoted to said ribs, substantially as described.
In testimony whereof I affix my signature in presence of two Witnesses.
YVALTER ARNOLD.
