To all whom it may concern:
Be it known that I, DANIEL SHAW WAUGH, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in Rock-Drilling Machines, of which the following is a specification.
The present invention relates to rock drills, and the primary object is to provide a structure of the type operated by motive fluid, preferably air, said structure being very compact and the parts thereof accessi ble, while retaining the advantages that are secured in modern drills of this type.
In the drawings :Figure 1 is a'view in elevatio-n'of the drill. Figs. 2, 3 and 4 are enlarged sectional views through the same, Figs. 2 and 3 joining on the lines A.'A and B-B, and Figs. 3 and 4 joining on the-lines CC and DD. Fig. 5 is a sectional view corresponding to Fig. 3, but showing the automatic valve in a difi'erent position. Fig. 6 is a sectional view on the line 66 of Fig. 3. Fig. 7 is a sectional vieu on the line 77 of Fig. 3. Fig. 8 is a sectional view on the line 88 of Fig. 3. Fig. 9, is a sectional view on the line 9-9 of Fig. 3. Fig. 10 is a sectional view on the line 1010 of Fig. 3. Fig. 11' is a sectional view on the line 1111 of Fig. 3. Fig. 12 is a sectional view on the line 1212 of Fig. 1. Fig. 13 is a sectional view on the line 1313 of Fig. 1. 1
Similar reference numerals designate corresponding -parts' inall the figures of the drawings.
In the embodiment disclosed, the motor, as is usual in this type of structures, comprises a cylinder member 14, having a piston chamber 15 therein, in. which reciprocates a piston 16. A chuck 17 is carried by one end of the cylinder member for receiving the usual drill tool or steel 18, and a tappet 19 Y is interposed between the drill tool or steel, and the piston for transmitting the force of the blow from the latter to the former. The cylinder member 14 is mounted at its rear end on a head block 20 having a boss 21 that fits within the cylinder member, which boss is provided with a pocket 22 that re-v ceives a projection 23 on therear endof the piston, thereby providing an air cushion for said piston on its return stroke, as hereinafter more fully described.
The head block 20has a rearwardly ex!- tending sleeve 24, on which is mounted the cylinder 25 of the motive fluid-actuated means for holding the tool to its work. This cylinder 25 is secured in place upon the sleeve 24 by-a split collar 26 surrounding the end ofthe cylinder and the sleeve, and having at its innerend an internal groove 27 that. receives the rib 28 formed upon the cylinder 25. A bolt 29 serves to maintain the collar 23 in itsclamping position. The said collar 26 is providedxon diametrically opposite sides with ears 29 The rear end' of the cylinder member 14 has corresponding ears 30. Through the alined ears are passed clamping bolts 31 that thus serve to maintain the two cylinders in upon the head block 20.
In addition, the bolts 31 constitute means operative positions for securing in place the handle for turning the drill. This handle is illustrated at 32, and is secured to a yoke 33 that partially surrounds the cylinder member 14, being provided with terminal ears 34, through which said bolts pass;
The cylinder 25is provided at its outer end; with a cap 35, through which passes a piston rod'36, terminating at its outer end in a spur 37, and having its inner end se cured to a piston that operates in the cylinder 25. This piston consists of a head 38 threaded to therod 36, and having its opposite end cup-shaped, as illustrated at 39 to receive a packing cup 40 borne against by a washer 41. The said cup 40 and washer 41 are held against rotation with respect to the head 38 by a pin 42 engaging these three elements and the parts are maintained in coiiperative relation by a bolt 43 that passes through the washer 41 and the cup 40, and is threaded into the head 38.. This bolt 43 is provided with a'recessed head 44 having an annular groove 45 in which is placed a split yielding frictio-nring 46 having its opposite corners beveled off and arranged to frictionally engage in "the bore 47 of the sleeve24, so as to hold the piston in its innermost position.
The head block 20 constitutes a casing, both for the initial. and the automatic valve. It is therefore bored out transversely, as shown at 48, the bore being slightly tapered, and snugiy receiving a valve cage 49 that is also open ended and tapered slightly,'the end having the bore of smaller diameter be- 'ing provided with an internal flange 50. The said head block or valve casing is provided at one side with a motive fluid inletnipple 51 that opens through the cage. Anair port 52 opens through one side of the cage into a passage 53 leading into the bore 47 of the sleeve 24, and consequently into the-cylinder 25 of the feeding mechanism. From this bore 47, and consequently from the air feed cylinder 25, an outlet port 54 extends through the head block and cage into the interior of said cage. A series of ports 55 lead from the opposite side of the cage to the rear end of-the piston chamber 15, and one or more passageways 56 lead from the front end of the piston chamber 15 through the port 57 to the valve cage, opening theret-hrough through one or more ports 58, as shown in Fig. 8.
A rotary initial or throttle valve 59 is mounted in the cage 49, being held abutted against the flange 50 by a spring 60 that bears against its larger end, said spring being borne against by a plug 61, located in the opposite end of the head block. .The
end of the valve 59, opposite the spring 60,
projects through the cage. and through the head block, said projecting end having fitted thereon, a handle 62 that is held in place by a bolt 63, and is prevented from turning on thevalve by a key 64. The amount of rotation of the handle, and consequently of thevalve, is controlled by a stop 65 that operates in the cut-away portion 66 of said handle, and the difi'erentdesired positions of the handle are determined by a plunger 67 carried by the handle, and engaging in sockets 68 formed in the end of the head block. The plunger has a rounded end that can be forced out of the sockets bylthe movement of the handle, and is urged into said sockets by a spring 69 bearing against its rear end. 1
The valve 59 is provided in one end with a motive fluid-receiving chamber 70 having an inlet port 71 that is movable into and out of register with the inlet nipple 51 of the head block. It furthermore as in one side an outlet port 72 that is movable into andout of communication with the port 52 leading to the feed cylinder. In addition, an initial port 73, shown in Fig. 11, is provided, which when the valve moves from closed position, communicates with the nip pic 51, before the port 71 comes into communication with said nipple, thus admitting a small amount of air into the feed cylinder prior to the opening of any of the other rts, so as to move the'drill to its work fore it is started in -operation as hereinafter described. Furthermore by reference to 11, it Wlll be seen that the valve 5 cm 49 and head block 20 are provided with an exhaust passageway 73, so arranged that when the initial valve '59 is in closed position, the port 71 will be in communication with the passage 53 and the port 72 will be in communication with the passage 73 thus providing an exhaust vent from the feed cylinder which will permit the piston to be moved to its innermost position. The initial valve 59 is furthermore provided with an internal automatic 'Valve chamber74 separated from the chamber 70 by a partition 75. A port 76 is formed 'through the initiaLvalve, and is movable into and out of communication with the port 54 leading from the feed cylinder, the
arrangement being such that the port 7 6 y will register with the port 54 when the port 71 is in register with the inlet nipple 51, and the port 72 is in register with the port 52. The port 7 3, however, moves into communicati'on with the nipple 51, before the port 76 communicates with the port 54, and
consequently, as above explained, the motive fluid will be admitted to the feed cylinder before the air or motive fluid enters the automatic valve chamber. The rotary valve 59, in addition, is provided with a pair of ports 77, as shown in Fig. 6, which move lnto register with the ports 55, leading to the rear end of the piston chamber 15, and said valve 59 also has other ports 78, which move into register with the passageways 56,
leading from the front end of the piston chamber 15, Theseports will of course be 1n communication when the port 76 is in .communication with the port 54.
Leading from the end of the automatic valve chamber 74, which is opposite the plug 61, are opposite exhaust passages 79,
which, as shown in Fig. 10, open through the valve cage, and through the head block into the open air. Communication between the said automatic valve chamber. 74 and the exhaust passages 79 is secured through a reduced part 80 of the said chamber.
A reciprocatory automatic valve 81 is mounted in the automatic valve chamber 74, and has an annular groove 82 formed between two portions of different diameters, designated respectively 83 and 84, the portion 83 being of greater diameter than the portion 84. This groove 82 is always in communication with the port 76, and consequently with the motive fluid supply, when the imtial valve is open. The movement of the valve is sufficient to alternately expose the .ports 77 to the groove 82, and also the ports 78 to said roove 82, so as to thus alternately supply t e motive fluid to opposite ends of the piston chamber 15, and thereby efi'ect the reciprocation of the piston. The said valve is also provided with an internal exhaust passageway 85 extending therethrough, and whenthe said. valve is in'the position shown in Fig. 5, this exhaust passageway is not only in communication with the passageways 79, but also with-the ports 77, so that air in rear of the piston 16 can exhaust through the channel thus produced,
while air is being admitted to the front endward, while the motive fluid in advance of saidpiston will exhaust through the port 57 and passageway 56, thence past the end of the valve, inasmuch as the ports 78 are uncovered, andout through the exhaust pas- 1 sageways 79. Y
The automatic valve 81 is positively moved in opposite directions by live motive fluid delivered from the cylinder member. To this end, a passageway 86 leads from an intermediate portion of the piston chamber 15 to the end ofthe automatic valve chamber 74:. into which the plug 61 projects and the said plug 61 has a central inwardly extending pilot 87 that snugly fits inthe'exhaust passage 85 of the automatic valve when the valve is in the position shown. in Fig. 3. 'Another passageway 88 communicates with the piston chamber 15 in advance of the passageway 86 through a port 89, and
this passageway 88- leads to the valve cage, where it communicates with a concave slot 90 in the exterior of said valve cage this slot being shown in Figs. 9 and 10. The initial valve is provided with ports 91 that coinmunicate with the said passage and open into the automatic valve chamber 74 directly adjacent to the contracted portion 80. The automatic valve 85 has a pilot 92 on this end that enters into the reduced portion 80 leaving a small space, however, that is in communication with the ports 91 illustratedin F 9. v I i The operation of the machine is substantially as. follows: Assuming an air hose or other supply of motive fluid connected to the nipple 51; and the initial valve 59 in its closed position, with the feed piston in its innermost position, it the handle 62 is moved initially, to bring the port 73 into communication with the inlet nipple 51, the -m0t-We fluid will enter said port 73, pass through the chamber and through the port 71- (which is-now in communication with the port 52), thence passin through the passageway 53, will enter the eed cylinden. The piston will thus be moved outwardly, or rather, the cylinder with the mechanism carried thereby, will be moved with respect to the piston, the spur ofsaid piston being placed against a suitable abutment, and as a result, the machine will be this change takes place,
moved to its work, but inasmuch as the port 76 is still out of communication with the port 54, the motor will be at rest. It now, the initial valve is moved still farther, the various ports above described, will all be brought into communication, and as a'result, the motive fluid will be in the groove 82. Assuming the automatic valve in the position shown in Fig. 3, the motive fluid will pass through the ports 55, behind the piston, driving said piston forwardly until it strikes the tappet. The air in advance of said piston will exhaust through the port 57, the passageway 56 thence through the ports .58- and 78, past the end of the automatic valve, and out through the exhaust passages ,79; As soon as the piston-l6 in itsfor-ward movement uncovers the passageway-86, the motive fluid will enter said passage, andv acting. against the end of the auto matic valve will move it to the opposite end of its valve chamber. W hen this occurs the motive fluid. entering through the ports 7 6 and around the automatic valve, will be transferred into the passageway 56, and enter the front end of the piston chamber through the port 57, driving the piston rearwardly, while the exhaust will take place through the passage 88, until covered, and also through the ports 55, the exhaust passage 85in the automatic valve, and thence into the exhaust passages 79, Where it will escape to the outer air. In this return movement, the automatic valve will beheld in a position to permit this exhaust by the' pressure of the exhaust itselflhnd it will therefore dro to anintermediate position, as fully explained-in my Patent, No. 915,813, dated Mar. 23, 1909- As soon as the piston approaches the limit of its rearward movement, the port 89 is uncovered, thus admitting live motivefluid to the passage 88, whence-it passes through the groove 90, and port 91 against the opposite end of the autoinatic valve, moving saidvalve again to the position shown in Fig. 3, the pilot 87 entering the exhaust passage 85 of said automatic valve before the pilot 92 of the automatic valve leaves the contracted portion 80. As the piston 16. will reach its limit of movement, and the projection or boss 23 thereof entering the pocket 22 will produce an air cushion that will start the piston on its'return stroke.
In order that the parts may properly opcrate, it is desirable that they should be eii'ectivelylubri'cated, and to this end, a. lubricant. reservoir 93 is employed that is. screwed into the. end of the head block, opposite to the valve handle 62. This reservoir has a filling opening 94, closed by a plug 95, audits inner end is partially formed by the plug 61 already described,
which is threaded thereinto. Ports 96 are formed in this reservoir and lead from the cage 49, and a pocket 100 formed in the initial valve, moves lnto alinement with the port 99 and the port' 78. Whenthe initial valve is open, the oil or lubricant will fill the pocket 100, and when theivalve is closed, it will flow from said pocket into the ports 78, and thence be carried by the air to all parts of the mechanism.
From the foregoing, it is thought .that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art,
without further description, and'it will be understood that various changes in the size, shape, proportion and minor details of construction, may be resorted to without departing from the spirit or scope of the invention. 7
