` TUNNELING-MACHINE Patentedapru 13, 190e.

Application filed October 23, 1905. Serial No. 288,880.

To atl 'whom tt 'may concern: t

Be it known that l, EDWARD F.l TERRY, a

citizen ot' the United States, and a resident of New Yorklcity, borough of Manhattan, inthe county and State of New York, have invented .a newand Improved Tunneling- Machine, of which the following is a specivfication.

The primary object of this machine is to cut a tunnel through the rock without the There are nine gangs of drills which I will *refer` to asthe central gang A., lside gangs B', B2, B3, B4 and the cornerfgangs C', (l2, C, C4. The central and side gangs are of such'size and location that in their movementshereinafter described they cover substantially the whole lield of the vend of the tunnel, the pathway of the side gangs adjoining the pathway of the central gang.

The gangs of drills above referred to are supported and operated so that they receive the following movements: (l) the reciprocating drill movements; (2) a bodily forward feed movement; (3) a sidewise movement transverse to the tunnel line and-preferably in a circle, with the axis of the tunnel'- as a center; (4). when required,l a sidewise canting, movement toward either side of the tunnel; (5) when requirerha vertical canting movement toward the top or'th'e bot-tom of the tunnel; when required for changing of drill-heads or other purposes, a bodily backwar movement.

'prefer to build the structure for supporting the drill-Gangs and impartingl to them the motions a ove referred to. v

D is a carriage supported by the two pairs of wheels E', E2, F', F2. This carriage carries .its own engine shown (Fig. l) as a fourcylinder engine with the cylinders mounted in pairs G and. G2;power for the engine is supplied from any suitable source through pipe X and branches and s (lfig. 1I). The pair of cylinders G', G2, are adapted respectively for driving its wheels and E2, to impart to the carnage thefor- "'ward feeding movement or the reverse,`and for simultaneously imparting the sidewise rotating movement to the drill-gangs. The carriage D also carries the means or a portion ot' the means (as, for. example, the air storage tank H and its appurtenances) utilized for 'supplying the air for the pneumatic' operation of the drills.

I is the main tool-head lixed to" the orward end of the rotating hollow shaft J having its bearings in the frame D. This main tool-head I carriesl the pneumatic-cylinder K from which the central gang-drills A; are operated; also, the cylinders L', L2,

L and L* from which the side-drill-gangs are respectively operated; also, the cylinders `M, M2, M3 and M4 by which the corner.V

drill-gangs are respectively operated.

Having now describedthe general features of the machine as I prefer it, I will proceed to describe lthe same more in detail. y

The carriage D is composed of a horizontal frame consisting of the transverse girders d', cl2, (Z3 between which is built a platform' d* constituting the floor of the engine room for the engines G', (if. Resting upon said girders el, (Z2 and (Zfj is the arch F confornfing approximately to the roof otl the tunnel ard4 forming the ceiling for the engine room of the engines-G', 11". This arch will taper very slightly from front to rear so to provide for the canti'ng of the carriage.

el, ZT are diverging lugs by which the `girder el is supported upon the wheels E E2.

d?, d are a corresponding pail-'lof lugs by which the girders d'2. d are supported upon the wheels F', F2. Box girders 11', nl and l :y girders c 2, Z13 connect the lugs fore and aft I will now descrlbe the form inwhich I and carry journals for the shafts c', e, j f2 upon which the wheels are fixed. The rear hearing j is mounted upon the top of the les' uprights H", l-I1 and the Ihorizontals H8. opening N is left between the lugs on s1te sidesand beneath the girders d',

carnage. The engine cylinders G may beconnected' so asto drive the wheelsF-, F2 (either or. both) 'as follows: g is a chain through'whichl A a" sprocket on the engine [shaft drives a sprocket g2 i'xed to the sleeve g? mounted on t e rotatable shaft g*.` One endfofthe atingwith avclutch gisplined to the s at'f g1, andthe other end of the sleeve gafca'rries a beveled' gear g11 which I'meshes with'a'fb'eveled-gear g7 fixed tothe 'shaft 911- extending, across thecarria'ge andv carrying at its oppo` site end a -beveled gear. g meshing withjja.,

circular rim vhof the head I. is fixed.: The internal. gear g, already referred to, isv

beveled gear g1 fast to the 'send of a sleeve g.11 mounted on the rotatable shaft 912 and' carrying at its opposite end a clutch inember adapted toengage the clutch '913 splined to theshaft 912. It willnow be seen that'by shifting the clutches g5 and g, the enginel cylinders G may be made'v to drive either or both the shafts g4' and 912, andthat* by reversing the engine cylinders G', either or both of said shafts may be driven in either direction, and 'for communicating corresponding movements 'and control to the wheels F', F2 it only remains to connect the shaft g4 with the wheel shaft f b the worm i with the wheel shaft f2 by the worm g14 and gear g15 and to connect t e-shaft g12 g1 and gear g11.

When the wheels F F2 are both driven abreast, the axis of the shaft J. will be maintained in alinement with the axis of the tunnel andthe bore will be continued straightV ahead. .,When, however, either one of the wheels is driven slightly ahead of the other, the shaft J will be canted toward thel side of the backward wheel and the bore will be continued in a curve toward that side.

. In order to cant thev shaft J up or down -so as to continue the bore either in a downward or upward curvature, the wheels E', E2 are provlcled with the means of. adjustment shown lin detail in Fig. 5. The wheel has its bearings a frame e4 which slides in a guideway e5 and is provided with a set screw e for adjusting its position in said guide; way. By supporting the rear end of the frame temporarily on a jack at'v the inclination of the shaft J desired, the set screws 6 of the wheels E E2 respectively, can be set so as to adjust the wheels for the desired degree of'inclination. 1 It will nowbe obvious that by the adjustment of the set 'screws e and by controlling the speed with which the wheels F, F2 are driven, a resultant cant of the carriage D may be obtained to incline the shaft J at `any desired angle to the axis of'the tunnel and thus continue the bore atta curvature in v through which the yworkmen can pass the .to the .front p ate of the drill head I, las shown -in the case of box 13 in Fig. 2; these boxes @time any' desireddirection, either upward, downin anyintermediate Ilcws: The chain 918 connects the sprcket on the enine shaft with asprocket g1 fasttfo the rotata le shaft g on theopposite end of which isl fixed the pinion '-g21 driving thej;

'inside gear'g22 fixedto themain drillhead I. y The main-drill-h'eadI lmay be constructed fas followszzz' is the hub containing the central cylinden To the front'a'nd rearl of this hub.. are bolted the plates @"j and 2l and lfrom between these: plates radiate the four larms 1, z'5,j Each arm is;` built of angle irons and plates and the hub and'arms together constitute a spider upon which the fixed to the front of this rim and cylinders L\, L1,l La, L4 are fixed inside this rim at the extremityofeach arm. Proj ecting'hori f-zontally from the rim 7 are the four arms is, ii, 111, .z'11, the extremities lof which are, re-

spectively, braced from the plate z" by the boxes 711,2, 13, 14 and 15 so that eacharm and a bracket carrying the cylinder for acorner dmu'gang Boxes 12, 13, 14, and '7115 are preferably formed with Hat sides, a perpend1cular front, and an inclined vtop slanting from `a point adjacent'the front of each box oint atwhich it 'is secured to the in addition to serving as braces for arms 8, z 0, 21, and @11, afford protection for'the cor# ner drill gang cylinders M, M2, M3 and M1l mounted adjacent the .lower front edge-of the'boxes respectively.

10 are openings fore and aft through the main head I for the passage of workmen.

The compressed air for operating the drills is supplied from a source outside the tunnel, enters this apparatus through the pipe zf, the storaofe .tank H, the pipe and through the stuffing box h, into .the rotating shaft J through which it passes, from which 4it proceeds throughthe openings j into the passage j* in the steel castingj5 and thence into` the passage j of the hub i 'its brace, in conjunction, form substantially whence it is distributed to the various cyl- 'I lnders and controlledby suitable valves to automatically voperate the therein in a skilled in the art of pneumatic drills.

a isthe head by which the'central gang of drills A is carried. This head or carrier is composed substantially o f two pairs of girders a, a2, a, a1, forming substantially a drill pistons manner familar to those cross with each other. As shown 3) the gir-ders a3, a* are continuous from end to end, while the girders a, ai are each in two sections cxtendlng from opposlte 'sides of a3, a* adjacent the center thereof. As `de-l sired, girders a', a2 may inturn be made continuous, .or both` sets of girders may` be made continuous land adapted to cross ad` jacent the center. yThese girders are heldin position by being secured at the vrear by web platesto a` steel casting a containing .the .rearwardly extending guides a? and forwardly extending guides w* within the head itself. The` head or carrier a is supported upon the four guide-rods a that yextend I from`the back to the front of the head I and thence forward -through the guides' a7, agof the head a.

The piston-rod 7u of the cylinder K is connected with the center of the casting a. Thus, the operation of the cylinder K is to reciprocate the drill-head or carrier a so asI to impart to the drill-gang A the drilling movement upon the guide-rods a. The individual dri 1s comprised by the drill-gang A are held within the girders, as shown in construction and a description oi' one will.

answer for al'l. ,They correspond substantially with the central head or carrier excepting that in the side heads the girders by which the drills are held are' arranged parallel instead of crosswise ot' each other.

kReferring to Fig. l, b is the ,q'irder into A which is slid the series of drill-holdingplates 7119 and which is held by the web du from the face of the casting o containing the guides o? .and o on the guide-rod b. Rods?)12 connect the webs b transversely. The piston-rod Z from the cylinder is connected with the center of the castingb.

The. heads, or carriers, for the corner gangs of drills are all of the same construction and, therefore, a description ot' one will answer for all.

Having reference to Figs. 9 and l0, the piston-rod c carries at its front end a steel casting c containing a screwthreaded prof jec'tion c2 upon which is screwed the `drillholding-p'late c3 held by the key c4. ll`he drills are introduced into the holesthrough the plate detached. It is then screwed i onto the casting c and keyed by c4.

The lcorner rill-cylinders have an inclependent swinging movement whereby the direction of the corner drills maybe adjusted with reference to the radial plane from the' axis of the. tunnel which may be described as follows. In this regard, all 'of with each other, and a the cylindersl'i, i'lg, i 3, M4 correspond description of one win do for an. The `Cylinder is provided lwith side trunnions m which have their bearings in the side members of the supportingarm as is, enablingthe cylinder to be swung in the direction indicated by the arrows in Fig. 2, from position in radial plane to the position inclined thereto, as shownvin Fim 2 or even farther-if desired;

In order to lock the :cylinder-,at any de- I .sired inclination, the mechanism shownin Fig. 7 is employed. Surrounding one of the trunnions is a serrated surface m engaging with a corresponding serrated piece m2 in which the trunnion may rotate but which is fixed to the arm member is. By. loosening the nut m3, theparts m', wai-may be moved to any adjustment required, and then by tightening the nut ma the serrations .will hold the parts at said adjustment.

o', o2, (Fig. d) are water pipes extending tothe frontof the machine, for supplying water with which to spray the face ot' the rock and, if necessary, to wash the cuttings back toward the rear of the machine on the bottom of the tunnel.

To remove the rock cuttings from the .front to the rear of the machine, provide the 4conveying apparatus P.' lThis consists of a 'series ofscrapingblades p pivotally secured at th'eupper rend to a bar p. which is suspended Aby four hangers pt pivoted to the bottom of the platform d". lThese arms are swung by the eccentric rods' p3 and eccentrics p* from the shaft g8. lVhen the bar p swings backward, the blades p are in vertical position so as to scrape the material backward along the bottom ot' the tunnel and up onto the incline p5 from which they are discharged upon'the delivery belt 79". When the bar p swingsforward, the following mechanism causes the blades/p to oscillate upward, as shown in dotted lines in Fig. 2. A i

p7 is a' rocker forming a pin and slot -connection with thisrod and pivoted at p" to l the bar p7.

p1 is a dog pivoted to the rocker fr at g5 and held normally in line with the rocker by the spring pn with itsI rear end resting against the pivot 'p8 of the rocker.'

p13 is ay projection fixed 'to the carriagefraine. As the dog passes this projection in going forward, it movesthe rocker into the dotted position-so as to oscillate'the blades 7) upward. As, however'. the dog passes the projection p1 in going backward, it moves upon its own pivot ,ou and allows the rocker p3 to remain in full line position so that the blades p remain'vertical and act as Scrapers. i

The modification 'shown in Fi 12, resenablesin general, theV constructionv already described, with the'excepton that the forward feed is produced by hydraulic ram and the compressed air is supplied from a motor and-pump mounted u pon the carriage and rill cylinders returns to the com ressed. airpumps. Within the' hollow shaft-J is introduced a hollow pistonrod Q and piston g." Water under pressure Vpasses from the pipe g through this pistonrod and piston into the space ga. A sto is provided for the rear of the piston-rod by the inclined arms g4, g5 pressed against- -the top and bottom of thev tunnel; The hy-l draulic pressure-"inthe space 3tendsto feed-the whole.machine forwa'r. as fast iasvthe action Q fthe drills permits. 1

, R is an electric motormounted upon the carriage D anddriving an airlpump Stfrom which 4compressed air is forced through the passage j, to sup ly the various drill cylinders. There.' will e lapump S for every two. drill cylinders. The air compressed by 'the piston s of the pump lwill be sufficient to supply two of the drill cylindersV and as it compresses the'air behind the pistons of the drill cylinders, the action'of the pump-pis# ton s2 will be to exhaust the air from in front of the two drill-pistons. Since thepumps S are mounted upon the nonrotating carriage D while the passages j? into which the pumps discharge are in the rotating lpart A j, it is necessary to provide'the connection T in which the plates t, t2 are 'nonrotatable and the ring t3 rotates with the shaft. 'The ring t? is provided with two annular groovest4, t5 that are constantly in connection with the' pump passages 156,157. Both the grooves t4 and t5 are' in communication with the pas- Having thus described my invention, I claim as new and desire to secure by Letters Patent: v
