BEGULATING-VALVE FOR To all whom it may concern:
Be it known that I, HAROLD I. STAGE, a citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented a certain new and useful Improvement in Regulating-Va'lves for Drill-Feeding Means, 4 of which the following is a specification.
This invention relates to a class'of rock drills known as stopers and in particular to a valve construction for maintaining a constantly regulated pressure in the feed cylinder for holding the drillup the rock when it is in operation. p The objects of the present invention are to provide a valve between the fluid pressure supply and the feed cylinder which willenable the operator to control the'pressure exerted within the feed cylinder to force,- the drill upwardly to the work. A further object of the invention is t0' make this valve in a form which will be compact, readily operated by the workman and one which will enable the pressure within the feeding cylinder to be maintained at a constant pressure, when the valve has been set .by the operator, within very close. limits regardless of the character of rdckbeing drilled;
With the aboveijand other objects in view my invention consists in the features of construction and operationset forth in the following specification.
In the drawings annexed hereto and formin a part hereof: (a Y %igure 1 showsan outside view in-elevation of a complete stoper or air feed drill 'eprovided withc the present invention,

DRILL-FEEDING MEANS.
Patented Dec. 7,1920.
1919 Serial No. 332,645.
l inder of a stoper which may be of any well known type, that shown being 'of the ham mer drill type with handrotating means shown at 2. At 3 is-shown the feed cylinder which is of theusual type containing a piston or plunger forcing the point 4 away from the cylinder 3 when pressure is admltted at the upper end of the cylinder. The throttle valve shown at 5 receives its supply of fluid pressure through conduits 6 and 6 in the usual manner.
Indrilling different types of rock the pressure with which the drill is heldagainst the work must necessarily be varied within rather wide limits to obtain the most effective drilling, especially is this so when seamy rock is being operated on, and when the type tain the pressure within the feed cylinder 3-at any pressure desired under control of. the operator without regard to the rapidity of drilling or type'of rock being drilled. This isalocpmplished in the following man:
The throttle valve 5 is shown provided with a radial passage 7 which, when in its open position as shown in Fig. 3 per- .mits fluid to pass directly from the supply conduit 6 into passages 8 as shown in ig 2. Passing through the passages or con- (luit 8 the fluid passes through block 9 past a valve 10 shown in Fig. 2 in open position which is its normal position, as will hereinafter appear. The fluid the-n enters cavity 11 and thence into conduit 12 and into the cylinder pressure cavity 13 within the feed cylinder 3.
Within the cavity 11 a plunger 14 'is'pro vided pressed toward.the'left by means of a spring 15,its forward face presslng against one end of -'the valve-10 and tending to hold it in open position againsta-spring 16 which surrounds the valve 10 and exerts relatively light pressure tending to force it into closed position. ,Inserted within-the cavity 11 is a screw .plug 17 carrying a threaded bolt 18,
rotation of which moves forwardly or back the nut 19- which*-: is mounted upon the threaded portion ofbolt 18.- The nut 19 is restrained from rotating by means. of flutes and recesses shown respectivelyat 20 and 21 in Fig. 4%. Rotation of the bolt is accom-' 25 the pressure again drops within the pli shedby means of winged nut 22 which forces the nut 19 forwardly and back varying the pressure exerted by spring 15 against- 14 tending to force it tothe right against pressure ofthe spring -15 and with movelo'wed to close. With the spring 15 adjusted to-a given ressure by the adjustment of nut 19 it will lie obvious thatia given pressure will just balance the pressure to hold the 15 valve in a closed position and that.when the pressure within cavity 11 is lower than that critical pressure the plunger 14 will move to the left thus 0 ening the valve 10 andpermitting a little uid to pass through .20 the flutes 10 provided in valve 10 and thus a being adapted to close when the .fluld withenter the pressure chamber 13,- andas-soon as the critical pressure'is reached in cavity .11, plunger 14 will be moved to the right and-thus the valve 10 will be closed until ressure chamber 13 and cavity 11. Shoul the pressure within cavity 11 increase above the.
writical pressure the plunger 14 will be moved to the right far enough to open the exhaust conduit '23 thus allowing some of the fluid within cavity 11 to escape. Inthe operation of. starting the drill the throttle valve is partially opened and as the valve 10 is initially and normally open .the 35 drill 1 is permitted to rise to the work and the hammer started inj'operation. as the drilling is started and the throttle opened to its fully opened .position, the pres- .sure of sprin may be readily ad'usted sired pressure 7 for feeding the drill forwardly and holding the drill against the rock is obtained within the-feed cylinder- 3=and as the drilling progresses this pressure may be-varied as desired, by simply rotating I the wing'nut 22 slightly to either increase or decrease. the pressure of spring 15. v
