` Be it known that I, CHARLES BURLEIGH, of Fitchburg, inthe county of Worcesterland State of l Massachusetts, have invented lcer.- tain Improvements in Machinery forDrilling Rocks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in whichd l Figure lis a side elevation of my improved machine for` drilling rocks. Fig. Zisa plan of the same. Fig. 3 is a vertical longitudinal section through the center of the same. Fig. el:` is a tran sversesection through the machine on the line a: a; of Fig.`1.` Fig. 5 is a trans" verse section on the line y y of Fig. 1. Fig. `6` is an enlarged view of the under side ofthe valve-chest and valve. Fig. 7 is a horizontal section through the center of the same on the line z z of Fig.` 6. Fig. 8 is a transverse section through the same on the line fw w of Fig. 6'; Fig. 9 is an elevation of oneY end .of the pistonbar with its annular cam detached.`
Fig. 10 is a detail, to be referred to hereinail` ter.
' In machines for drilling rocks there are sev-l. eral requisites,the principal of which are to give the drill a reciprocating motion toward and from the rock to effect the cutting; to rc,- tate the drill artially at each stroke, and to feed it forwar the necessary amount, according to its penetration. It is also; desirable, when several drills are operated together upon the same frame, to be able to advance orwithdraw them from the work, and that they should have l a .universalmotiom so` that they may be pointed in` any direction required.
` The nature ofthe work to be performed also bringslso greata strain on all the parts that y reciprocate with the drill that itis of great importance thatthese parts shouldsbe `few number, of `simple construction, and possess great strength.
My invention hasfor its object to accomplish all of the above requisites, as will now be de-i scribed in suchterms that others'skilledin the art may understand and use my invention.
In the said drawings, A is thcjcylinder, within which` works; a piston driven by compressed air or steam, in a well-known manner.`
This cylinder isproyided with` a projecting rib, a, on each side, these ribs fitting into grooves b in a slide or drill frame, B, and on this frame `the cylinder and partsctmnected` therewith are made" progresses, as will b hereinafter. V,The dr' under side, and slid l in a clamp, C,`whicl1`is c 011s an `ordinary bcx which ni umn or` bar D, upon, l
ed, and is made 1n t screws, by which" the the required position'. box c is a beveled disk, the upper portionlof the in two piecesg and B', c andnuts f, by,` loosenin can be revolved aroun tl or advanced or withdr drill, and itwill thus` b l `of this clamp a universa mct ntis together witha movem "ow (lo work. E is the pistonh1 vt0 the piston g, Aandcarr es at the drill F, the piston-b except at its rearend,` wh for the reception of th makin g the machine co is secured toV and revol `end of the drillfframefB, ported, as seen in Fig with sufficient irictiont lp when the drill is in op which it mayb@ rev zquired. l To the re r en secured ahollowtube o asa guide for jthe fee` alsofor the ratche Upon the rear endl ofA a cap, I, containingthe J, either made in onei `cured together, the

on the insideof` t `nut torevolvefre y, Insteadofthe" `eetl-scr of thepistonfbar,
be attached perm en screw through t feed-screw will frame, renderin The manner in shoulder, 18, and thus allows it to be revolved freely. As the piston-bar moves forward toward the rock, the ratchet Z is turned, so that the pawl m falls into the next succeeding notch, there being more weight and friction v on the piston-bar than on the ratchet, in consequence of which the latter is turned as required; on the backward stroke, however,
the ratchet is held stationary by the pawl m, and the feather 7c causes the piston-bar to be partially revolved by means of the spiral groove j. Instead of a spiral groove, however, the piston-bar may be made polygonal in cross-section and twisted, so .that in passing through an opening in the ratchet of corresponding form it will be turned as required; or, instead of the piston-bar itself being grooved or twisted, a piece attached thereto may be turned in a similar manner 'by passing through the ratchet or rotating device. By thus causing the piston-bar, or an attachment thereto, to4 slide through the ratchet, which effects its partial revolution, insteadof having the ratchet attached to and carried forward with the drill-spindle, I ain enabled to avoid much of the shock on the working,v
parts, and consequently lessen the liability of their being broken, which is a matter of vital importance in machines of this description.
The valve K, through which vthe compressed air or steam is admitted into the cylinder A.,
and the manner in which it is operated, will I now be described. This valve, which is what i may be termed a hollow double-acting' rotary valve, works in a chest or casing, L, (seen enlarged in Figs. 6, 7, and 8,) and is so constructed that the pressure of the air or steam will hold it firmly upon its seat. The valve K is formed with two ports, n, Fig. 10, which connect with the exhaust-passage o in the interior, and is also provided with longitudinal bars or toes p of suiiicient Width to cover 'the ports q in the valve-chest L, which communicate with the interior of the cylinder. there being a space,
r, round the valve, so that the air or steam may pass through the holes s, Fig. 6, on both sides, round to either port in the valve-chest. When the valve is in a. position to take ,air
or steam at either port, the port at its oppoi site end will be in sucha position that the eX- haust will pass through it'into the interior of the valve, and this valve being in line with the cylinder, the exhaust air or steam is discharged toward the drill, and serves to blowv away the dust or water from the working j parts of the machine. 'The required motion .is given to the valve K by means of a rod, t,
which is supported in standards 19 on the casing H and cap I, and is rocked or partially revolved by means of the jointed tappets u t, the lower ends of which project through slots in the casing H. Thesetappets are raised at the required times by means of an annular cam, M, secured to the rear end of the pistonbar E, which passes under them as the bar E is reciprocated, the form of the lower ends o f these tappets being such as to give the required motions to the valve.. By moving the rear tappet u on the valve-rod t toward or from the cylinder, the air or steam will be cut off sooner or later, so that the drill may be operated to advantage in any desired position, either vertically or horizontally. In stead of the cam M being attached directly to the piston-bar E, it may be secured to a piece conthrough a slot, 20, in the casing H, into ay position to .be struck and raised by the annular can M as it passes beneath it, which thus causes the pawl c to revolve the nut J on the screw G,which, through the connections described, feeds forward the drill as required. 'lhe vend ofthe lever a' which passes through the slot 2O is so curved and formed that theannular cam M does not 'lift it sufficiently to eect the feed until after it has raised the tappet o onthe forward stroke to shift the valve, and by this means I am enabled to regulate the feed to correspond with the penetration of the drill, for if the pistonb'ar does not advance to a certain. point the cam M will not raise the end of the lever sufficiently to cause the pawl c to fall into the next succeeding tooth in the ratchetnut J, and consequently there will be no feed of the drill. The valve, however, will be shifted at each stroke without reference to the feed.
VV-hatI claim as my invention, .and desire to secure'by Letters Patent, is-
l. The annular projection M upon the pis- Iton-bari?, or an attachment thereto, for the purpose of operating the valveand feeding device, or either of them, substantially as set forth.
2. The stationary rotating device, when 'operated by the. movements of the piston-bar,
substantially as shownand described.
3. The hollow valve K, with its chest L, 'y arranged to operate in line with the axis of the cylinder, substantially as described.
4:. The clamp C, consisting of the boxl c and pieces A and B', constructed and operating vsubstantially as described, in combination' with the slide or drill frame B. l
