AIR-FEED CUllT'ROL ESE. ROCK DRILLS.
i neared Application filed July 523,
To all tU/wfib it may concern.
Be it lrnown that l. Few ti. Smarts, a citizen oil the United. Sta residing at lilaston, in the county oi" l lOTl'llltlllptOll and if ate of l' ennsylvaiia, have ii'ivented c tain new and useful Improvements in ail. l eed Control for Rock Drills, of w'iich the following is a specificat on.
This invention relates to .tluid. pressure. operated rocl: drills of the hammer type, but more particularly to air iced control for the feeding element or" stope drill.
The operator wishes to maintain full tation and hammer newer with reducer. air steed when going through a sort spot for instance, but with the usual air teed controlling device, he must talre his hand oil the rotation handle provided on the machine, and turn the throttle and he may not do this quickly enough to avoid trouble.
The primary object of the present invention is to enable the operator to control the feeding element or air feed cylinder directly from the drill handle without removing his hand. The control may be effected by a simple pressure of the fingers, preit erably by the thumb accordin to the type of handle provided. The air reed may thus be substantially instantaneously controlled and dropped when required or restored to full air feed in a simple manner.
Further objects of the invention will herematter appear and to all or" these ends the invention consists of the devices and fea tures of construction shown in the RCCOH1- panying drawings, in which- Figure 1 is a side elevation partly in vertical section of a stope drill embodying the invention,
Figure 2 is an enlarged detailed side elevation of a portion of the handle, and
Figure 3 is a horizontal sectional. view through the handle on the line 33 of Fig-- ure 2 looking in the direction of the arrows.
Referring to the drawings, a stope drill is illustrated in Figure 1 having the usual cylinder A and front head l3 carrying the drill steel C. The front head is connected to the cylinder as by means of the usual side bolts D. The cylinder A and its operativ' parts comprise the percussive element of the tool for imparting the impact blows of the piston hammer to the drill steel. The drill steel may be rotated by any suitable means,
in this instance a machine oi? the independ- Specification of Letters Patent.

iion type being illustrated having .4
the rotation motor casing E formed in the back end portion of the machine.
The feeding elen'zcnt compri. r il'ced cylinder ll havingthe is m (l and piston rod H provided with t rock oniog point .1. Between the heel: end por. tion l3 and the air ted cylinder F located he head block K and. the cylinder A, back end portion lil, head block K. and air teed cylinder F are held together as by means of the through bolts L. i lotive fluid is admitted to the percussive and feeding elements of the machine thr lush the inlet if) controlled by the throttle l in the head block K. The head block is provided with a rotation handle P for the ma .hinc, although the handle could be connected as desired to any suitable portion of the casing. In this instance, the handle P is provided with the downward extension Q, forming a convenient portion to be grasped by the hand of the operator.
In accordance with my inve ition instead of controlling the air feed in the usual mannor, as by means oi. the throttle l I provide a valve ll in the handle controlling ports and passages leading to the feeding element, therel'iy enabling the operator to regulate the feeding element in accordance with the requirements of the Work without removing his hand from the handle.
in this nstance, the handle is preierably hollow provided with the passage 55 extend from a port T at the inner end or" the lie to a valve chamber U near the handle extension The valve chamber U coininunicates with the atmosphere through the end of the handle by means or" the port and the chamber is closed by means of the screw threaded plug N between which and the valve R a spring X is compressed so that the valve normally closes the atmospheric port V. The valve is preterablyprd vided with an operating button Y at its end forming a convenient device for manipulation by the thumb Z of the operator.
The handle l is preferably removably connected to the head block it: in this instance the inner end or the handle being provided with a tapered portion at having a reduced neclr 2' through which the port T opens. ll hcn the handle is held in position in the head block K as by means of the nut 0 communication is atlorded from the air the us u al feed cylinder F through the passage d to the space around the reduced neck 5 and from thence through the passage 8 1n the handle to the valve chamber U.
chine and adapted to be grasped and held by the operator, and. a valve located near the outer end of said handle controlling ports and passages leading from the feeding ele ment, thereby enabling tl e operator to reduce the pressure in the feeding; element in. accordance with the requirements or the Work, Without removing his hand tromthe handle.
2. A rock drill having a percussive element and a fluid pressure feeding element, a hollow rotation handle rigidly secured to the machine and communicating with the feeding element and the atmosphere, said handle being adapted to be grasped and held by the hand of the operator, and a valve located near the outer end of said handle for reducing the pressure in the feeding element, thereby enabling the operator to regulate the feeding element in accordance with the requirements of the Work without removing his hand trom the handle.
3. A rock drill having a percussive ele ment and a fluid pressure feeding element, a hollow rotation handle removably and rigidly eonnected to the drill casing and comin unicating with the feeding element and. the atmosphere said handle being adapted to be grasped and held by the operator, and a valve located near the outer end of said handle controlling an exhaust port from the said feeding element, whereby the pressure in the feeding element may be reduced substantially instantaneously in accordance with the requirements of the Work.
In testimony whereof I have signed this specification.
FRED M. siiirren.
