AUTOMATIC VALVE.

tomatic Valves, of which the following is a specification. n
This invention relates to improvements in automatic valves especially adapted for use ,in a 'fluid operated percussive tool provided with an independent rotating motor.
In particular the automatic valve is designed to be inserted in the conduit leading from the throttle valve to the admission side of the rotating motor so that the amount of fluid supplied 'to this rotating motor may be adjusted manually as well as controlled automatically in accordance with variations in the amount of power required to operate the rotating motor.
More particularly the invention relates to improvements in the automatic regulating valve for controlling theJ supply of fiuid to a rotating motor described in my copending application Serial Number 233,978, filed May 11th, 1918.
One of the vobjectsV of the present invention is toV provide means to manually control the supply of fluid tov an independent rotating motor applied to a rotating hammer diillsupplemental to the automatic regulating of the supply accomplished as shown to application.
It frequently occurs that the motors adapted to drive drill rotating means are mounted more or less loosely so that there is a variable amount of leakage through the motor casing without doing a corresponding amount of work. In addition, the motor wears and for that reason more loosely engages its casing and more leakage must be compensated for. The present invention relates particularly to a means to manually adjust or vary the amount of fluid supplied to the independent rotating motor as this leakage becomes greater or when the motor may require an increased amount of motive fluid as when operating in more diflicult ground.V Y
A further object is to provide a simple,
. easily operated and manuallyV controlled .means to accomplish this variation in addition to the automatic regulation taken care of by the valve itself.
With the above and other objects in view my invention consists in the features of construction and operation set forth in the following specificationI and claims and illustrated on the accompanying drawings, forniing1 a part hereof, in which,-
*igure 1 shows a longitudinal section through a hammer drill provided with the improved form of automatic regulating valve;
Fig. 2, an enlarged view in section of the automatic valve alone;
F ig. 3, a sectional view of a throttle valve nade in accordance with the present invenion.
Referring more particularly to the figures of the-drawing, 1 refers to the cylinder of a hammer drill having a hammer or piston 2 operating therein.V A rotating motor, shown generally at 3, is connected through suitable reducing gearing to a chuck 4 in which the drill bit 5 is inserted and by means of whichgthe drill bit 5 is rotated. These parts are all usually found in independent rotating motor drills and it is not thought will'require any additional description. Motive fluid to operate the rotating motor 3 is supplied through throttle valve,
or intothe back head 11. Within the valve i casing A9 is a valve 13 spring-pressed against the forward end 14: of the v alve casing 9 by means of a spring 15. I The forward end of the valve casing 14 is tapered on its outside, as shown at 16, and in its forwardinost position is adapted to take up against a seat 17 Lateral radial passages 18 are provided in the valve casing about opposite the main or full diametered portion of the valve 13 so that with the valve 13 positioned as shown in Fig. 2 the radial passages 18 are entirely closed off and no fluid can pass through the radial passages 18 and out past the axial Vformed in the drill body or back head 11.
passages 19 and forwardly into the rotating motor 3. `With the valve casing 9 positioned slightly away from the seat 17 a smallamount oflluid can pass through conduit 7 past the outside of the forward tapered end of the valve casing 9. This annular space may be variedby altering the position of valve casing 9 by merely rotating it slightly and if desired it may be tightened against the seat 17 to prevent any fluid from passing through conduit 7 as when it is not desired to rotate the drill bit 5. Normally the position of valve casing 9 is set so that an amount of fluid may pass around the valve casing 9 and thus through conduit 7 to rotate the drill bit 5 at its normal speed when it is not being yforced against the rock.
' It will be seen from the above that'when the back pressure increases between the au.
tomatic valve13 and the rotating motor 3 caused 'by slowing the rotation of the motor due to an increased load, that the valve 13 will tend to open against the pressure applied by this spring 15 until such a point is reached that the radial passages 18 become fully opened. The amount of fluid which may pass through the passages is then sufficient to operate the motor 3 when used under its maximum load conditions. 'The tension of spring 15 may be adjusted by varying the position of the screwed plug 20. In practice the tension `of this spring 15 is so adjusted that an increased baclr pressure on the valve 13 caused by an increased load and reduction in speed of the motor is sufficient to completely open the ports or pas- Y sages 18 only under maximum overload con'- ditions.
-To accomplish the additional feature of the adjustment for air leakage and to regulate the speed of rotation of the steel for different conditions of drilling, the valve body 9 may befwithdrawn farther from its seat 17 allowing an additional small amount of lluid to `pass around the valve casing between the valve casing 9.`and seat 17, thus adding to the amount allowed to pass through the conduit 7. A lock nut 21 is provided for securely clamping the valve casing 9 in any adjusted position that may be desired, it being sullicient to merely loosen this lock nut 21 to easily rotate-and adjust the vvalve casing 9. i Y f In the form of the invention shown in Fig. 3 the automatic valve 22 having eX'- actly the same formV of valve and also the same form of valve casing 23 is applied in a valve of the usual globe or throttle type. This is shown in its simplest form at 24. To adjust this easily, the valve casing is provided with a valve wheel 25 by means of which it may be readily adjusted. The action of this valve is similar in every way to that'shown in Fig. 2, and may be applied in a main supply line to any fluid consuming element, so that the .maximum fluid passing may be readily adjusted and may also have the'feature of partially closing the valve automatically when the fluid demanded is materially reduced.
It is to be `understood that the present showing and description disclose only one specific embodiment of the present invention and that other forms and modifications are included within 'the spirit and scope of the invention as expressed in the appended claims.
Wvhat I claim is:
1. In a fluid operated percussive tool, the combination of a rotation motor and a valve for automatically regulating the supply of fluid to said motor, said valve comprising a casing bodily movable in a conduit leading to the motor, a normally closed spring pressed regulating valve within said movable casing adapted to control the amount of fluid passing from the conduit through ports in the sides and end of the casing to the motor, said casing being Vadjustable longitudinally in the said conduit to permit the Vpassage of a limited amount of motive fluid around the outside of the casing tol the motor.
2. In a fluid operated percussive tool, the combination of a rotation motor and a valve for automatically regulating the supply of fluid to said motor, said valve comprising a casing bodily movable in a conduit leading v tothe motor, a normally closed spring pressed regulating` valve within said movable casing adapted to control the amount of fluid passing from thc'couduit through ports in the sides and end ofthe casing to the motor, said casing being adjustable longitudinally in the said conduit to permit the passage of a limited amount of motive fluid around the outside of the casing to the motor, said valve being operated in a direction opposed to the spring solely by pressure built up ahead Vof the motor.,
In testimony whereof, I havehereunto set my hand.
