' This invention relates to a rail drilling machine operated by powerfor drilling the rails of a railway track and has for an object to provide a machine of this class which f will drill large holes in the web of the rail, which will drill the hole accurately in a marked centre, which will drill holes close to the ends of a single rail, which canbe readily rolled along the rail, which is easily positiondfor drilling and which can be quickly removed from the track. These and other objects of the invention. will be more fully understood from the following chine and Fig. 2 is an elevation. Fig. 3

adjusting the supp'ortingshoe, Figs. 9 and v10 are details of the eccentric bearings for the rollers, Fig. 11 is a side elevation of the complete machine, Fig. 12 is a part eleva tion from the motor end and Figs. 13 and 1 1 are details. l I

Modern railroads designed for heavy trai fie are laid withv rails weighing from 100 to 135 lbs. to the yard and have a 'web of approximately in thickness. It .is found that these rails wear more rapidly at the ends where the wheels pass :Erom one rail to the other'than elsewhere andthis has led to a process of cropping rail in order to extend *its life. Cropping consists in cutting off a portion of the end of the rail where it is V worn and providinga new set .of holes for can the splice bars so thatithe rail'can be relaid after the worn portion is removed. I

- Heretotorera'ils have been taken up from v the track and removed to a machine shop where the ends are sawn ofliand the rail is redrilled preparatory to its relaying. The

ends are now burned off with an oxy-acetylene torch without taking up the rails butit is not-economical to drill the ends with hand drills} The power operated. drill, of the P t .we i qn, enables the ra l t be specification and the accompanying drawings; in which, Flg'. 1 is a plan View ,of'the 1na-.

drilled in the track or on the end of the ties thereby eiiecting great economies in this process of rail cropping. This machin'ejis' "rsnr creme.

rails that are setup on the ends of the ties preparatory to laying or it will drill a single is readily disengaged from the rail and removed in an emergency such as might arise in clearing the track for an approaching train. I I v w This invention is designed along the lines shownin U. S. Patent,1,42 1,194-,, issued in my name on June 27,1922. A number of fea Y titres are embodied inthis'machine which are not found in the former.- These arebrought 8O aboutby the increased Weight and power of themachine, bythe necessity for drilling through a, marked point and by the necessity for quickly positioning the drill tovarfous sizes of rail and to 'varying conditions of track and ties so that the time required to operated and ren oved iromthe .track bytwo position the drill will not be out of propore tion to the time consumed in drilling the hole.

Referring to the resents the end section of a} railway rail,- 12, Fig.1 is the main frame of the machine which is mounted to roll upon the, rollers 13 and 14 on one rail of the track. The entire machine is balanced upon theserollers so that it can be moved along the trackwith comparatively.little effort. The 'IEI21I116.,12

dr awings,;l1, Fig. Strep} has right angle eXtensfions15 and 16..

The extension v15 supports the, gearing 1 and the drill and the extension 16 supports the engine or motor. The feeding mechanism for the drill is housed in 17 and-18 is an. adjustable shoe whereby the elevation of the'drill is adjusted. The ha dle 1-9 at one end of the frame andthe handles'20 and 21 at .theoppositeen'd enable'the machine to be lifted from the track by two men. The

frame 16 is formed in a. T to supportlthe handl as indicated-at and 25 is the b d moi the engine or motor 23 having the fly wheel 24 and connected. to the driving shaft 26.

vThe gear transmission fromthe motor to the drill spindle is shown in Fig. 4;. The

engine or motor shaft is indicated by 26 upon which the gear 27 is mounted; this thebevel gear '32 at the opposite end. gear engages the bevel gear 33 mounted upon gear engages 28 which is mounted integrally with the gear 29 which engages 80 mounted upon the horizontal shaft 31 wh ch carrles This the vertical shaft 34: which, at the lower end,

The gears are supported the covers? by the gear case lil which is provided with The bevel gears are, enclosed by'the cover i l and the'bevelgearson the drill spindle are enclosed by the casting 15. The drill spindle 37 has a spline 88 -which engages the bevel gear '36 causing the drill-39 to rotate therewith. The drill 39 is secured in the chuck 40 and the spindle rotatesin the-bearing 4:1. 16, 417 and 48 Fig". aroma an upstanding pipe rail by means of which the machine may be guided upon the track and-also forms a convenient support for the engine or motor controls which are not-shown-in the drawings.

Thedrill'feeding mechanism is housed in the casing 51 and comprises a sliding'member 52in which the endlof the spindle 53 rotates. 'This spindle is-securedby the nut 54 at the end to the sliding member and a thrust ball bearing 55 is introduced between the sliding member 52 and the spindle'37. It will be noted from that the rack bar56 is. secured to the sliding member 52 and is the medium "by which the sliding moi e d towards or. away from the drillingposition. The periphery of this wheel is corrugated so that it may be graspedfirmly by the hand.

On; the V shaft 59 the gear wheel '62 is mounted. This wheel is much larger in' diameterthan 58and through its operation a considerable leverage is obtained'against the. working of the drill.

Gear 62 is protected by a cover 67 by which it is entirely enclosed.

I Rotatably mounted uponthesh'aft'59 is the bracket 63 supporting the socket 6 1 of the feeding'handle 65. This handle is provided w th a pawl 66 by means of which it maybe latched to the gear 62 so'that the handle and gearmove together, or it maybe unlatched so that the feeding handlecan be moved independently of 62. ;The pawl 66 is operated by the latch rod 69'and is nor* mally held inengagement with coilspring 68- The latchr0d can be released manually bythe latch rod handle 70 audit is also released automatically when the feed handle is in a predetermined posi- "10' l 62 by the tion by the tappet 71, pivotedat 72 to the, w

of the track. Considerable variation exists bet-ween'the ties and the rail and in order to obtain"v the propervposition of the drill with relation tothe rail, it is necessary to so I make frequent adjustments of the position 0f the shoe 18. This shoe is pivotedjona shaft 81 toIthe projection-82 of the casting 51,]as shown in Fig.- 6.. A' lug' 83 formed integral with 18 is developedninto a worm quadrant-84c. This is engaged by the worm 88, Fig. ported bybralcket'85. .Turninghan'dle 87 adjusts the position of 18 with amicro'meter adjustment. q

"Thefqu'adrant 91 is mounted on ,shaft-93, ;Fig. 1 and; is

normally raised as indicated at'108 Fig.1?)

by the coil spring 94. This holds the :quadrant clearof the rail and the splice bars andbolts as the machine is moved 'on'its-rollers. The. quadrant is lowered to the position shown in Fig. 3 by means of the pedal 100 and bar99 bolted to the bracket 98 whichis free to turn on shaft93. A lug 97 'onthis bracket engages a lug 97 on collar which.

turns shaft. 93 and lowers "the quadrant.

When thepedal is released it is returned 'to its normal. position by." the spring 101.

lVhen' the quadrant is'lowered itis auto mat-ically latched in the lowered position by the plunger'lOt-i working in the boss 102'and engagmgm hole 103' Fig. 14: in thefquadrant. This plunger is held in the engaging position by the spring 104 and is released by the arm 105. which is pivoted'at 106 and] operated the arm107; 111m 105 isforked on the end to engage the bent over end of plunger 103. Pressure applied to 107' to withdraw plunger 1 03. permits the quadrant t return'to the raised position instantly.

. lllis pivot-ally .connectedto theframe 16 as Adetailed plan view'of this-mechanism is shown in F g. 13.

In orderthat the machine may be properly supported when on the ground, afoot shown. in Figs, .1 5111(13. This foot is level with the rail and in combination with the shoe 18 forms a rigid support. It is neces- I sary to turn the foot out of the way when the machine is placed on or operated on the rail, For this purpose a latch 113, is provided havinga plunger working 115, and

'engagingholes inthe frame 16 such as 114.

hen the latch 113 engages 114 the foot is positioned on line b F i 3 and as shown in Fig.11.' Y

a The machine is clamped to the rail by the mechanism shown in Fig- 3. Lugs .121 projecting from the frame 12, Fig. 1, form. the bearings for shaft 122 upon which the clamp ing arm 123 is mounted, also the clamping members 124 and 125,. screw 126 adjusted by the knob 127 is screwed into each of the clamping members. These screws terminate in spheres 128 which engage the head of the rail as shown and can'be adjusted to engage below the rail head and thus assist in hol ding the machine down on thetrackor can be adjusted to engage the side of the rail or to take up a position between. these points.

The clamping member is slot-ted-onits" longitudinal centre and is tightly clamped onl26 by the locking wheel 129. The wheel 130 performs the samefunction for clam ingmember 124. A toothed quadrant 131 is-secured to the frame. 'Thisquadrant has its centre on shaft122and' holds the clamping lever 123 iii-position by means of the latch 133 pivoted'at 134 and engaging the quadranhait 135.;- Thisflatchiis released by the latch rod 132.

1 The height of the frame above the rail head is determined by the rollers 13 and 14. For this purpose these rollers are provided I with eccentric bearings having a quick method of adjustment. The detail construc tion of this hearing is shown in Figs. 9 and 10. The roller'shaft 141 is carried by the eccentric disc 142 which is provided with a flange 143 engaging .the frame 144. A toothed quadrant 145 is also secured to this frame. A projected bracket 146 formed in tegral with the eccentric disc has a jaw 147 in which the toothed latch'148 is pivoted to engage the toothed quadrant 145. A lever handle 149 is secured to 1.46 and a plunger 150 in this handle releases the latch 148 so that'the eccentric may be rotated 1n the tral'l'y between them.

It .Will be noted from Fig. 1 that the roll drilledcl oseto the end "of the rail it is appaircnt that one of the rollers will overhang the rail and if there isno adjacent railthis roller will have no support. Inorder to j I operate the machine under these conditions the leveling screws operated by the hand wheels and 156, Fig. 1 are provided. Thesescrews, it will be noted, are located close to the centre of the machine and therefore close to the drill. The hand wheel 156',

terminatesin the' point 158 engaging the fore, holds the'machinefin its'properr'elw tion to the ,rail' whenone ofjtherollersare projecting. beyond the rail.'

the rail and itsheight above therail 'is adjusted by the eccentrics'of the rollers until the point of the drill aligns withthe marking for the hole, The drill is then levelled by. turning theshoe 18 with the handle 87.

Thequa'drant 91 islowered and latched and the/clamping lever is operated to clamp the rail head. The drill isknow brought up to thewdrilling position the handwheel 61 and afterthemotor is started it is fedby lever 65. One movement of this lever, will feed. the-drill through the web of the rail.
