Letters Patent No. 102,383, dated April 26, 1870,.

IMPROVEMSHT IN MACHINERY FOR DRILLING- ROCK.

The Schedule referred 'co in these Lettera, Patent and making part of the same.

To all whom it may conce-rn Be it known that I, WILLIAM H. ELLIOT, of' the city, county, and State of New York, have invented a new and improved Machinery for Excavating Roch; and l do hereby' declare that the following is a full and exact description thereof, reference beingr had to the accompanying drawings 'and to the letters of reference marked thereon.

Similar letters of reference indicate the same dei vices in all the figures.

To enable others skilled iu the arts to comprehend, make, and use ,niyinventiom I'will proceed to describe its nature, construction, and operation,` The nature of my invention consists in suspending a drilling-machine, by attaching it 'to th'e lower end of a rigidsuspending shaft, which is .made adjustable in a vertical direct-ion in suitable ways orguides, so that said machine may be brought' to and held rigidly in any required position by the suspending shaft, either with `or without the assistance of braces; in providing a joint or bearing, by which theshaft and drillingmachine may be made toswing in Aection across the excavation, Iin addition `to the horizontal axis of the drilling-machine, by whiclrthe feed is directed; in the -employment of ways or guides, by which the sus?.- pending shaft and drilling-machine may be made to traverse across the excavation, in connection with joint, by which these devices may be made to swing across the excavation, for the purpose of throwing the drilling-machine under projecting rock; in the em, ployment, in connection with the last-mentioned ways and joint, of another joint,by which the suspending shaft may be made to swing in a direction parallel with the excavation and with the track upon which the carrnns; and

It further consists in the arrangement of pulleys in such relation to the suspending shaft and drilling-maw chine, that the drivingbelt running over said pulleys may carry the power of the engine to the drill without danger of derangement by changing the position of the suspending shaft or drilling-machine.

The object of my invention is to provide means of placing and vsupporting a rock or ore-drilling machine in any necessaryposition in the excavation below the car, being p artihnlarly applicable. to deep rock cuttings, such as sewers, cellars, canal, and railroad cuts.

The modification of my invention shown in the drawings is applicable to sewers.

In the excavation of cellars or other Wide cuts,'it would bie necessary to place several machines on the same cross-ways, so that several holes may be drilled at the same time in a line across the excavation.

In excavating sewers, a drilling-machine should be under o', over 11,

teeth cnt on the edge of placed oneaoh endv of the car.

themachines are then made fast.

My invention is applied in a manner similar to that which was patented by nie on the 18th of June, 1867-, and for a particular description of the drilling-machine herein referred to, I make special reference to my patent oi' June 18, 1867, No. 65,802, which was granted to me for improvements in the construction and operation of machines for drilling rock and ore.

The earth is rst removed from over the rock` where the sewer is to be cut. A railroad track -is then laid down on each side ofthe excavation, and the car with the machinery upon it is then run lupon the l track.'I The drilling-machines are then loweredato the `dock lty means of windlass 1', and by means f the several joints placed in any desirai'ille position, and

By supporting the several machines cnindependent shafts, one drill may bev placed near the bottom of the excavation, while others may be usedl near the top.

The car should be propelled on the track bythe same engine that drives the drilling-machines.

The frame m should have its axis of motion in the axis of shaft cf, and may be made to slide on ways, and be supported independent of the shaft. 1 i

Thev drill and suspending shaft may be adjusted in any position across the car, by sliding thebed d on the ways d', using the pin t as a level' for moving the bed, and also as a bolt for making the bed fast to the ways.

Thebed (l should also be fastened by a clamp, similar to the fastening of the shaft g in the ways r.

IBy means of the screw-brace any desired inclination may be giveuto the swinging bed e.

Where there are several machines on the same cross-ways, it would be impossible in some cases to so place the car on the track as to apply all [the `drilis,to the proper places on the rock withouijlsome mcans'bli changing the position of the drills hrrelatiolnto-eaehl other and to the car. i j

By the use of the joint y and the screw-brace s, one machine may be thrown forward to a considerable distance, while another drill on the sameicross-ways may be thrown back under the car. Thus yall the machines may be brought to and held in the most desirable position for making the holes. A

rlhe swinging bed f is bolted to the plate 'u', and swings with it upon axis or bearing u, and is moved by worm u working in tbe teeth on the edge of plate fu'. By this means, the shaft g with the drilling-machine is made to s\ving across the excavation upon bearing fu, so asl to throw the" drill under projecting rocks in the sides of the excavation, and in other ways accommodate the position of the drilling-machine to 'the work to be done. v

' The bolt u secures the plate 'u' with the bed f in position. A

lhe suspending shaft g slides vertically in ways fr,

being raised and.lowered by windlass r, and boundrfast in the ways by clamp 1:. By these means the rillingmachine may be lowered to thev point where t e worl is to be done, and held there by the|glarn fv'. Jj

By making 'the suspending shaft itqsel gaij, stzill vertically, so as to be raised or lowered Ain w. ys'lor guides, instead of-making the drillingiachiue adj ust-r able at different heights upon the susgendng sbaft`,.I obtain several advantages. l

In the excavationof sewers or o `rer cuts of considerable length, it is necessary' to employ with the car having the drilling-machine upon `it, another car, provided`, as shown in my patent of November 23, 1869, with a shield, forpreventing the fragments of rock from flying, a drop for breaking rock, and a crane for lifting detached rock out of the excavation.

Now, to luse these two cars with the machinery upon them on the same excavation, when vthe track for the car to run upon is laid down uponl the' surface of the rock or earth, as it usually is, it is necessary that the suspending shaft having the drilling-machine upon its lower end should itself' be made adjustable vertically, so that everything suspended from the vear may be drawn up above the track to enable the ear to move oif over that part of the rock where no excavaof blasting, and also to give an opportunity -for the at tendant car to bring up and deposit the shield over thelcharges, and to breakup and lift out the rock after' lthe charges have been iired.

larlties ofthe sides and bottom of the cut often make it necessary to draw the suspending shaft, with the drilling-machine upon it, entirely out of the excavation before moving theV car at all. .The same is necessary --also to enable the car to pass over the ground from one lexca-fation to another. l

Sewers are often cut in rock from twelve to eighteen ieet in depth, and in many cases the holes have to be drilled in a horizontal direction at the bottom of the excavation. 'lo put the drillingmachine into the necessary position for this purpose, it must be supported upon a suspending device of sutiicient length to reach the| bottom, and it must be'raised and lowered by devices entirelyindependent o'f those that are used for feeding the drill into the rock.

The irregularities in the sides of the excavation are sometimes such-that it is impossible to drop the drilling-machine in a vertical line to the bottom of the excavation. In such cases, the joint u is made to give the suspending shaft the desired inclination, when it, with the drilling-machine upon `its lower end, may be allowed to slide down through ways or guides 'v till it reaches the bottom, where the machine has to be turned upon joint i, which directs the feeding devices, tiliithe drill is brought to the right elevation. illy means of theI horizontal .axis li", the drilling-machine may be made to take any necessary inclination, and is held in position by clamp j, which tightens the bearing upon the axis with sufficient firmness to prevent itfrom meri-ng, and by the vertical axis or shaft h' the inclination oit' the drill may be 'brought to any point of compass. Ii Y .The axis It' is hollow so as to allow the belt q to pass through it, and it is held in position by the loop and nut g. 'lhe hollow axis h' passes through the loop, which is tightened upon it by the' nut, so as to hold the d rill in 'any desired point of compass.

{1y-wheel, changing the inclination of'the drilling-ma lchine would not alter the length of belt q,- but the machine is more evenly balanced withthe bearings placed as shown, and consequently more securely held in place by clamp j.

The inner ends of braces w are fastened to the lower end of shaft g,.by means of universal joints; the outer lends of said braces slide through the ball and socket or universal jo nt w, and -are fastened by screws w',

,When the dlli g-machine is to be set in a new po- ,Litf n, the serel "s Elu are loosened, when the braces will Sll'jr through t 1e joints w, and accommodate themseines to the changed position of the machine. The joints also accommodate themselves to the changed position of the braces.

After the machine has been' set in the proper posiare again turned firmlyupon the tion, the sci-'eas braces, thereby hodding the shaft y and drilling-machine sccnrely in place.

of clamps or clutches, similar to those described in the patent before mentioned. Then, when the suspending herein described, o by any other suitable devices, the drilling-machine has the advantages of being held in place at thebottom of the cut by the strength and weight of' the car which carries it.

tion has been done, so that it may be out of the way fil n the excavation of narrow deep sewers, the irregnv In case the axis i were placed in the axis of the The car should be fastened to the track by means shaft g is fastener rigidly to the car by the devices- I have represented a round belt for driving the drilling-machine in the drawings, but a dat belt may be used with equal facility.'

The drilling -machine I employ with this apparatus is the same as that shown in my patentof 1867; but a steam drilling-machine may be used with elu'al facility. In that case, the flexible pipe for conducting steam would run directlyfrom the boiler to the drilling-machine, dispensing with the belt q and all the devices for conducting the'same to the drilling-ulachine.

During the process of drilling, the shaft g and frame h. remain stationary, their use being to hold the drilling-machine in position, the feed motions of the drill being entirelywithiu the 4imachine itself.

The power of the engine may be applied toraising or lowering the shaft g, and also to traversing the whole across the car, if desired.

Having described my invention,

'I desire to have secured to lne-by Letters Patent of the United States the following' claims, viz:

1. The combination of the rigid suspending shaft g', when made adjustable in a vertical direction upon ways or guides fr, and rigidly fastened to-a car by any 'leases suitable means, with.a drilling-'machine attached to its lower end, substantially as specified.

2. The combination of the rigid suspending shaft; g with the horizontal axis or bearing i and the joint u, substantially as and for the purpose specified.

3. The joint u, suitably supported -upon ways d', in combination with suspending shaft g and a drillingmachine, substantially as set forth.

4. The joint y, in combination with the ways ll and joint u, when these devices are so constructed and operated as to allow free movement ofthe supporting shaft of the drilling-machine, as described, and also so as to hold the said shaft rigidly iixed. to the car, substantially as described.

5, So arranging several pulleys, in relation to the suspending shaft g and hollow axis 7l', that the belt q shall `pass down to the drilling-machine and return ithrough said hollow axis, substantially as herein specified.

WM. H, ELLIOT.
