GROVER G.- TUTTLE, or :PHILLIPsBURG, NEW JERSEY, A ssTGNoE 'ro'INGERsoLL-RAND COMPANY, or JERSEY CITY-NEW JERSEY, A coRPoRAT'r'oN or NEW JERSEY.-
WATER-TUBE Application inea` september fo all whom't may concern: f f
Be it known thatgI, GROVER'G. TUTTLE, a citizen of the United States, andl a resident of Phillipsburg, county of Warren, and
'State of New Jersey, have invented a certain lVater-TubeConnection, of which the` following is a specification accompanied by' Thisinvention relates to rock drills, but more particularly to a water tube connectionfor fluid actuated rock drills of the hammer type. Y f f Y In rock drills employing tubes for conveying cleansing liquid to the drill hole,
considerable difficulty is at times experi- `enced in maintaining fluid tight joints between the tubes and the adjacent parts. Usually, such tubes are clamped firmly to their seat when the drill is assembled, but
i owing to thel eXtreme vibration set upp'whjeln the drill is in operation, the clampingmeans readily becom-e loosened and asportion of the cleansing agent finds ,its way into'the l percussive element ofthe drill vand washes away .the `lubricant-. Unless such leakage is early discoveredv andthe proper 'adjust. ments made, excessive wearv on thev movable parts of the drill will s take'place and thus l reduce the l.efficiency of the drill.
, It is an object of this linvention to prevent leakage of cleansing fluid, such as water, into the percussive element and other mov-v able parts of a rock drill, by means of spring devicesv for automatically compensating, for wear between the tubes and their seats.
v Other objects will bein part obvious and in part pointed out hereinafter.l The invention consists of the combinations of elements, features of construction and arrangement of parts substantially as heref inafterv described and more particularly pointed out kin the appended claims and illustrated in the accompanying drawing, in-v which Figure l is a view in elevation, partly in section, of so much of a rock drill as will Y serve to illustrate the invention, and
Figure 2 is a detail view in sectionof a back head equipped with a water tube connection constructed in accordance with the practice of the invention. l j Y Referring to the drawings, in which one modification of vthe* invention is embodiedl in a stoper type rock dri-ll, a cylinder A supports at its front end ay front head B` CONNECTION;
11, v1925.- J serial N6. 55,652.
ini-,q which is, inserted a drinsieei'c, The? Icylinder A is .provided with. a reciprocatory hammer piston D and an anvil vblock E" is interposed: betweenthe piston D and the drill steel C to transmit the-:blows of -saidf|` A ratchet ring.
piston to the drill steel. F is seated in the'rearwardl end, vof t-he cyldevices Gfcarried by a rifle barH engagingthe piston` D-in the usual manner for' f the purpose of imparting rotary movement coaxially withfthe cylinder A and has a pistonfK against which pressure fluid' may inder VA to cooperate with suitable ratchet j 'y act for raising or advancing the drill. A
back head L is in this instance interposed between vthe ratchet ring F and the cyl` inder J 'and serves to centralize saidratchet ring and the feeding [cylinder J. An suitable means may bev provided for holding-,the parts f r1fning.` the drill Ycasin'gin operative position, but such meansprefere ably consist ofQ suitable side .Y bolts (not shown) engaging various llugged portions of the front head B, the Lcylinder V-A'and l thejfeeding cylinder J, preferably exterior ofthedrillffy c Pressure fluid for actuating the percussive and feeding elements :is controlled by a throttle valve O in the back :head Lpand `l the distribution of pressure'fluid to the .per-
Y cussive cylindervA maybe controlled by a'y .suitable distribution valve (notshown) operative in a valve chest l). A throttle lever *V Y Q, secured to thethrottle valve O serves asa;
convenient means for manipulating said throttle valve, Y c
. In accordance with the practice of thel i invention,`a pair oftubesl andVS extend through the cylinder Aand are preferably arranged concentrically withrespect to yeach other'. The tube R in this instance serves to convey pressure` fluid through the drill.
and has a flangeT at one end to seat on a shoulder-U which'forms the bottom for Varecess V in theback head LQ The tube rS extends throughthe tube VR and through'-v the anvil block AE preferably toV a pointV near the forward end of said anvil block and is of somewhat smaller 'cross sectional f area than the bore ofthe tube R so that a passagev exists Atherebetween forV vconveying pressure fluid vto the drill steel. Communication is provided between the tube R and the throttle valve O by a port or series of ports X in the wall of Vthe Vtube R `and a .passage Y formed in the back headIJ. A port Z in the throttle valve 0 is adapted to register with vthe ypassage Y when the throttle valve is turned to the position to admit pressure lfluid to the vperc'ussive and feeding elements..
rfhe -t-ube'S in this instance is of considerably greatery length than tli'e'tube YR and eX- tends rearwardly through a water plug Zi to a point near the outer end of said water plug. The water plug` Z) 'is preferably hollow throughout its length and is screw tlireaded'as at c to engage corresponding screw threads formed in the lrecess V for holding said "water v'plug in "po'sition. By forming taperedtlireads on the plug Z) as indicated in the drawing, said plugniay be screwed firmly into the back head and thus prevent leakage of water alongithe threaded portion'ot'the plug. d
y In order to yieldably hold the tube R on its seat, a recessed retainer e is arranged slidably yin 'the water plug l) and is pie sed lirmly againsttlie flange T by a spring j' arranged between the'retainerc yanda shoulder g of a water tube guide 71. The water tube guide 7i, like the retainere, is also slidable in the 'water plug b and has a reduced forward extension jwliich extends into the interior `of :the retainer' @and cooperates therewith toform a fluidtight joint. The water tube'guide iin this instance provides a seat, it' for a bulb @carried bytlie tube S. In order to hold the bulb ojof.Y the tube S firi'nly uponftheseat 1, a yplunger y). bearing against the bulb o is arranged slid'ablyA in the water tube guide i and is actuated by a spring g wherebythe'bulb 0 .is held against removal from the seat l7c.
Suitable means are provided for'varying the tension of' the springs f and Q. To this end the outer end ofthe plug b is provided -witli internal sciew threads i to receive a vretaining plug s Awhich also'en'gages the end of the tube S. .Y
Cleansing fluid, such as water7 isconveyed to the recess V through a connection z5 and a passage it from whence it flows through a longitudinal external. groove u yin the water plug into a water plug cap i0 yand through arcstricted port Vminthe retaining plug S into thetube S. rllhe cap fw is in .this
instance 'screwed on the Aend of `the 'water plug to Vpre-vent leakage vof water from the recess V.
The advantages olf-the invention reside in the fact that any wear wliiclrniay. take place on the bulb 0 and the flange T and their seatsmay be automatically compensated for by the actionof the springs f and g. By this foi-moi'` construction, the springs f and Q may be placed under a strong tension at the time the water tube parts -are `assembled and due to' the lautomatic take-up yherein providedffurther attention on the part of the operator will be unnecessary. This feature is particularly advantageous in drills where ready access r4to the 'tube may not be had as for `instance `Jthe type vof drill illi'istr-ated in the drawings. v
