JOHN BERVIN, OF DURANGO, COLORADO.
ROCK-DRILL SUPPORT.
SPECIFICATION forming part of Letters Patent No. 474,206, dated May 3, 1892.
Application filed November 2, 1891. Serial No. 410,627. (No model.)
To all whom it may concern:
Be it known that 1, JOHN BERVIN, of Durango, in the county of La Plata and State of Colorado, have invented certain new and useful Improvements in Rock-Drill Supports; and I do hereby declare the following to be a f n11, clear, and exact description of the invenuon, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying d rawin gs,which form part of this specification. My invention relates to an improvement in rock-drill holders; and it consists in certain novel features of construction and in the combination and arrangement of parts, which will be fully described hereinafter, and more particularly referred to in the annexed claims. The object of my invention is to construct a support for adrill upon which the drill may be supported in any desired position while being operated, and thus do away with the services of one man for adjusting and turning the same, which would be necessary were the improved support notused.
Referring to the accompanying drawings, Figure 1 is a side elevation of my improved drill-support. Fig. 2 is a sectional View on the line X X of Fig. 1.
A represents a central post orsupport having a vertical slot A formed with the fluted walls, as shown. Extending through this slot and adapted to be secured at any desired point therein is the bolt B, which rests in and is held by the opposite concavities in the walls of the slot. Supported upon the boltB is the tilting and endwise-moving table 0, having an extended slotted portion D 011 its under side, through which the bolt 13 extends and by means of which the said tableis allowed a lateral movement on the said bolt. A dovetailed recess is formed on the upper face of the table extending its entire length, and adapted to move in this way or recess is the drill-carriage E, formed in cross-section, as shown. The under side of the table 0 is provided with teeth,or,in other words, is formed into a rack-bar, as shown at F, which are engaged' by corresponding teeth G, formed on the periphery of a wheel H, mounted upon an axle I, which is journaled in the depending bearings J on the under side of the table 0. The sides of the wheel are recessed, as shown,
so as to makeasnitable housing for the coiled springs K, one end of each of which being secured to the inner side of the flange portion of the wheel H and their opposite ends secured to the hub portions L of the stationary plates M, which are loosely mounted on the axle I. The upper sides or edges of these plates are flattened, so as to bear against the under side of the table O, and by this means they are prevented from turning with the said axle. The extended end of the shaft I is provided with a crank N. The purpose of the wheel H will be presently stated.
The upper portion of the carriage E is made circular in form, and adapted to move therein is the driving-rod O, which carries the drill at its inner end. Secured in the opposite ends of the cylindrical portion of the carriage are the hollow stops P P, and secured within the cylinder intermediate its length is the stop Q. Mounted on the rod 0 is a collar R, and wrapped around the said rod is a spiral spring S, which is confined within the cylinder by the said collar and the stop P. Secured to the rod 0 between the stops P and Q is a second collar R, having its outer end serrated to form a clutch, which is engaged by the traveling section T, through which the rod 0 passes. Around this section T are formed the spiral threads'T', which engage corresponding spiral grooves formed in the wall of the cylindrical portion of the carriage.
Secured around the rod 0 and confined by the section T and stop P is a spiral spring U, which forces the said section downward when the rod is moved in that direction.
The object of the wheel II, in connection with the spring K, is to hold the drill-carriage in an extended position and the drill adjacent the rock before the same receives the blow from the,driving-rod. If the drill is to V ing his tool always in position.
spring upon the wheel H and the latter upon the carriage will be to push the same up against the rock being drilled, holding the drill in contact therewith. The table 0, being set at the desired angle, no other adjustment will be required by the operator while drilling at that point, the spring and wheel hold- VVhen the drill is to be operated upon in a downwardlyinclined position, very little assistance is required of the springand wheel, as the weight of the carriage will be sufficient to hold the drill in contact with the rock being drilled.
In operation, the table being adjusted to the desired angle, the outer end of the rod 0 is struck with a mallet or hammer, forcing the said rod inward against the tension of the spring S. The stop R, being secured to the rod 0, moves therewith and away from the section T, whereupon the latter is forced downward by the spring U. Afterthe force of the blow upon the rod has been spent the latter is returned to its normal position by' the spring S. In this upward or return movement of the red the stop R comes in contact forced upward, and by the same operation is caused to revolve by the spiral threads T thereon engaging the corresponding grooves in the cylinder. The stop T being in engagement therewith it will readily be seen that the rod 0 and with it the drill is caused to revolve, thus doing away with the necessity of the operator turning his drill, which is a necessary operation in the use of a drill.'
The parts used in my improved device are few and simple and not liable to get out of repair. Drills of this construction have been found of great practical use. and especially commend themselvesto those desiring to save the expense of a second man, as drills of this character require two men to operate them. It has also been found useful where only a limited space is available and in which it would be impossible for two men to work. When used in a mine, the vertical support A is secured between the floor and roof of the mine; but when used whererock is taken from a bank the table and drill may be supported on a tripod.
Having thus described my invention, I
claim-- 1. The combination, with a support provided with a vertical slot and a horizontal passage, teeth formed on the under side of the said carriage, and a spring-actuated toothed wheel adapted to engage the said teeth on the carriage, the parts being combined to operate substantially as shown and described.
3. In a drill-support, an upright, a drillc'arrying table supported adjustably on said upright and provided with a dovetailed passage in its upper face, a drill-carriage adapted to move in said passage, teeth formed on the under side of the carriage, depending bearings, a toothed wheel journaled in said bearings, stationary disks supported on the axle of the said wheel, and springs which are connected at one end to the said disks and at their opposite ends to the wheel, the parts being combined to operate substantially as shown and described.
4. In a device of the character described, the combination, with the table and the drillcarriage supported thereon, of the wheel which engagesthe said carriage, having recessed sides, the stationary disks having inwardly-projecting hubs which' form drums, and springs which are connected at one end to the inner periphery of the wheel and at their opposite ends to. the said drums, substantially as shown and described.
5. The combination, with a recessed drillcarriage and a movable drill-rod therein, of
stops P and Q, secured within the carriage,
stop R, secured to the rod, spring S between stops P and R, clutch-section R on the rod, revoluble clutch-head T, adapted to move within the carriage and engage clutch-section R, stop P, and spring U between clutch T and the lastnamed stop, substantially as shown and described.
In testimony whereof I afiiX my signature in presence of two witnesses.
