lmpr ovement in Rock-Drilling Machines.
Witnesses My Patented June 11, 1872.
UNITED lii' PATENT OFFICE.
ASAHEL J. SEVERANCE, OF SAN FRANCISCO, CALIFORNIA.
IMPROVEMENT IN ROCK-DRILLING MACHINES.
Specification forming part of Letters Patent No. 127,712, dated June 11, 1872.
SPECIFICATION. To all whom it may concern:
Be it known that I, ASAHEL J. SEVERANCE, of the city and county of San Francisco, State of California, have invented Improvements in Rock-Drills; and I do hereby declare the following description and accompanying drawing are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvements without further invention or experiment.
My invention relates to that class of rockdrilling machines known as boring-drills, and is particularly applicable to the diamond-drill. Its object is to provide a revolving attachment for the drilling-machine by which the swivelhead and drill-rod can be turned to any point desired, and in which they can be elevated and lowered as necessary. 1 In order to explain my invention so that others can understand the same, rererence is had to the accompanying drawing forming a part of this specification, in which- Figure 1 shows a front view of my attachment, with the revolving carrier directly to the front. Fig. 2 is a side elevation. Fig. 3 is a top sectional view, showing the apparatus for supporting the drill.
AA represent two circular castings, shown more plainly at Fig. 3. These castings are connected together by plate 13, by means of which the entire attachment is secured to the drillingmachine or front end of a car. The circular castings A A are each provided with a circurevolving frame consists of the plate F, Fig. 1,
having a large slot, g, which extends almost its entire length. This plate is provided with arms H at both its upper and lower ends. The revolving frame is fitted between the two circular castings A A, the arms H resting upon the grooved faces. The shaft D passes through the extremity of both of the arms, and T-shaped bolts 1', shown at Fig. 2, are employed to hold the arms in place, moving in the T-shaped grooves and secured by nuts j. This frame can then be revolved about the shaft D as a center. K is a slide which is arranged to move up and. down in the slot 9. A U-shaped casting, l, is then employed both to support the shaft D and steady the slide. The shaft D passes through one extremity of the casting l and again through its center at an equal distance from the bend on the opposite leg of the U. The upper leg then extends forward and is secured to the upper side of the slide K. A bevel-wheel, m, is secured by a feather attachment upon the shaft D, between thetwo legs of the U shaped casting I, so as to move up and down with the casting, as desired. A short horizontal shaft, n, has one of its ends bearin g in the extremity of the U shaped casting l and passes through the slide K to the outside of the frame, where it carries the ordinary swivel-head and drill-rod. This same shaft also carries a bevel-wheel, 0, on its inner end, which engages with the bevel-wheel m, so that the revolution of the shaft D will transmit the same motion to the shaft n. The casting 1 serves to support the shaft D, especially when the strain comes upon or near its center, and always retains the teeth of the two bevel-wheels m and o in gear. The slide K, casting Z, shaft n, and bevel-wheels m and 0 can be moved up and down in-the slot 9 and along the shaft D to any point desired, and, when thus located and held in place by suitable clamps, the direction and position of the drill can be changed by revolving the frame about the vertical shaft D. Two or more of these attachments can be secured to one machine and all of them driven by the same shaft.
By this means I greatly improve the ordinary boring-drills, as each part of the device is supported at the proper point and can be separately regulated and adjusted to the work.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
1. The two circular castings A A, provided with the T.-shaped grooves and connected by the plate or bar B, substantially as and for the purpose above described.
2. The revolving-frame, consisting of the slotted plate F with its arms H, in combination with the circular castings A A and T-shaped bolts 17, substantially as and for the purpose above described.
3. The slide K, in combination with the U- shaped casting l and horizontal shaft n, substantially as and for the purpose above described.
4. The U-shaped casting Z, for the purpose specified.
5. A revolving attachment for rock-boring machines, consisting of the circular castings A A provided with T-shaped grooves, plate F, with its arms H, Tshaped bolts "5, and ver-
