To all lwhom it may concern c Be it known that I, HENRY H. VAUGHAN, of 'the city of Montreal, Province of Quebec, Dominion of Canada, have. invented certain new anduseful improvements in means for turning crank-pins while in place in driving-.wheels and boring the driving-wheel for the pin; and I do hereby declare that the following is a full, clear, and exact descrip- `tion thereof. I I
My invention 'relatesv particularly ,to ma'- chines for supporting the axle and driving wheels of locomotives and operating on the same; and it has for its object to provide a machine' of this type adapted to rectify the defects in the crank-pins of locomotive driving wheels due to wear or faulty construction, and to prepare the wheels, after having been mounted on the axle, to receive crank pms.
The invention may be said to consist of a machine for this purpose comprising means for supporting the axle and wheels and rigidly securing the same against displacement, a hollow spindle vadapted to envelop the crank-pin and carry a tool for acting upon the pin or a tool for boring a hole to receive a pin, and means for rotating` the said spindle andfeeding the same in the directionof the supportin means. For full comprehension however o my invention reference must be had to the accompanying drawings forming a part of this specilication, in which similar reference characters indicate the same parts, and wherein:
Figure 1 is a .side elevationl partly in sec-- tional view of-my improved machine with an axle and portions of a pair of driving wheels in dotted lines; Fig. 2 is a plan View thereof; Fig. 3 is a transverse sectional view taken on line A A Fi 1 and illustrating. in detail a portion of t e means for adjust-v ing the supports for the axle and wheels;
Fig. 4 is a sectional view taken at right angles to, and illustrating the same parts as, Fig. 3. Fig. 5 is a 'partelevation and part sectional view on line B\ B Fig. 2 of the tool carrying end of 'the machine; Fig. 6 is an elevation of the Aopposite end of the machine; Fig. 7 is a transverse vertical sectional view of the machine,l taken on line `C C Fig. 2 and illustrating particularly' lneanswherebyfu'the tool carrier is fed manually or mechanically. Fig. 8 illustrates f lof D D Fig. 2; Iligs.v 9 and 10 are enlarged plan and vertical sectional views, respectively, of the tool-carrying end of the hol low spindle, the sectional view .being taken o n hne E Fig.` 9; Fig. 11 is an axial sectional v1ew of the tool carrying member of the `machine fitted with a boring tool, and F1g. 12 1s a detail elevation of the tool-carr1er. Y 1 l The support for --the axle 2 and wheels 3 c onslsts of a pair of jacks 4 and 5 respectively having ll-blocks or heads 6 and guided 1n standards 7 bolted rigidly to a base 8 upon -whlch the working tool is also carried. The standards are vertically channeled to accommodate the jacks which are retained by cover plates 9 and have their lower ends protruding through the base and vengaged and hfted through a pair of combination hftmg nuts and bevel gears 10 held against vertical displacement by a part 12 of each standard; These gears are rotated indefpendently or in unison by bevel gears 14 and 15 mounted, respectively, rigidly on a pair of alined shafts 16 and 17 the abutting' ends of which carry rigidly thereon a pair of ratchetwheels 19 and 20 engaged by a. pair of pawls'21, 22, respectively, mounted .0n a lever- 23. By throwing either pawl into` engagement with its ratchet wheel either shaft and the jackin operative relation therewith may be raised or lowered at gagement both jacks may be raised or`lowered in unison.
The tool holder 'consistsY of a hollow spindle 50 of sufficient bore to receive locomotive crank-pins of the -largcst diameter. This spindle is revolubly mounted in a saddle 51 between which and the spindle .is'lo will, or by throwing both pawls into encated a bushing 52 to take up wear, while unnecessary axialA play of the spindle/,1S taken up by angular distance and Jam-nuts 53 and 54 vrespectively screwed upon the driven end of the. spindle, threaded for the purpose, a age 55 upon'the opposite end bearing, with sliding lit, upon the Hangedend 56 of the l). This drivenend protrudes beyond these nuts and is of reduced diameter and carries a gear 57 keyed thereto and operated by a pinion 58 mounted upon and in sliding rotation with a splined driving shaft 59 driven from -any available source of power. The cutting end of the spindle has cast in one therewith a standard 75 having a dove-tailed projection 70 with a radial opening 77 to accom* modate an adjusting screw 78, the upper cnd of which is rotatably seated in the upper end of the standard. A tool-carrier in the form of a slide 8O having a dovctail recess 81 slidably receiving the projection 76, is engaged and supported by a pin 82 formed on a nut 83 traveling on the screw 78. The tool, whether a cutter 85 or a bar carrying a burnishing roller 86, is clamped in a socket 87 in the slide 80 by screws 88 in which it is set in proper position to act upon the pin. The saddle over- Vhangs the sides of the base 8 flanged as at 90 beneath which a pair of 91 carried by the overhanging portion of the saddle slidably engage, thus preventing vertical displacement of the latter; an adjusting gib 92 and series of set-screws 93 taking up any unnecessary lateral play between the saddle andthe base. The saddle is automatically fed by means of a worm 100 on the driving shaft 59 and engaging a worm wheel' 101 fixed on a traverse shaft 102 mounted in the base and extending through the side lof the latter and having a handle 103 screwed thereon and free to be shifted on its thread to and fro for a limited distance along the shaft. This shaft is diminished to receive a sleeve 105 carrying a pair of spur gears 106, 107 and a hand-Wheel 108 all rigidly mounted thereon, the gears being inside the base and' the hand-wheel outside. Between the handle and hand-wheel, a clutch sleeve 110slidably keyed to the shaft, is adapted to be shifted into engagement with a clutchface 112 on the hub of the hand-wheel, by turning the handle in one direction, and disengaged therefrom by a spring 113 when the handle is turned in' the oppositel direction. The gear wheels 106, 107-intermesh with a second pair of gear-wheels 115 and 116 mounted rotatably on a shaft 120 cored out to receive a spindle 121. The adjacent sides of these.v gear-wheelsv are formed with clutch faces 129 and 130, and a clutch block 131, slidably mounted on the shaft, is connected to the spindle 121 by which such block is shifted into engagement with either of the gear-wheels 115 and 116 thereby effecting a rotative connection between the sleeve 105 and the shaft 120. A bevel gear 140, fixed upon this 1astf,mentioned shaft, drives a second bevel-gear 141 fixed upon a screw 142 mounted in bearings in -the base and engaging a nut 143 fixed upon the saddle. -The rotation ofthe screw in one direction or the other causes the saddle to travel accordingly. When theclutch 110 engages the hand-wheel clutch 112, the saddle will be fed mechanically and when disengaged t-he saddle can be fed manually. By pulling out the spindle 121 sufficiently to bring the outer gear wheel 116 into engagement, a relatively fast feed is obtained and a slower feed when gear-wheel 115 is engaged.
Instead of the revolving cutter 85 or burnishing roller 86 a rotating boring tool or axially-operating cutter may be tted into the hollow spindle. A tool suitable for the purpose consists of a circular bar 200 slotted at one end to have a cutter'201 secured therein by a wedge 202 and its opposite end seated in the reduced end of the spindle, a collar 203 formed rigidly thereon fitting within varrangement is illustrated in Fig. 11.
Operation: To turn down or burnish worn crank pins, the cutter or roller 86 is set in proper radial position, and the pins are operated on while the wheels are rigidly connected with their axle which is seated in the V-blocks 6. The jacks are thenv raised or lowered individually or together and the wheels rotated by hand until that near the cutter has its pin in axial alinement with the spindle in which angular position the wheels are clamped to the standards 7 by bolts 300. The saddle is then fed by hand until the cutting or burnishing tool is in position to act upon the pin, .and the mechanical feed is then thrown in the tool during operation traveling in a spiral path around 'the pin and turning down or burnishing the entire perimeter thereof, the pin being meanwhile accommodated by the bore of the spindle. The mechanical feed is then thrown out and the saddle returned to its first position by the manual feed, the wheels unclamped and the axle lifted and reversed and the wheels again adjusted and clamped and the pin of the other wheel acted upon. VWhen itis desired to bore the wheels to receive pins they are adjusted and clamped as above described and the tool 85 or 86 is removed and the boring tool 200 is in length -by a turn-buckle 351, and pivotally connected by an eye 352 to the base 8. The object of this deviceis to augment the adjustment lof the wheels to, and retain them in, proper quarteredl position by throwing the hook over one of the spokes and turning the turn-buckle until the hook takes hold.
A minute adjustment of the pin into axial alinement with the spindle can thus be readily obtained.
. What I claim` is as follows 1. A machine for turning crank pins while in place in driving wheels comprising in -combinatlon upright means for supporting and rigidly retaining .an axle with wheels in' place thereon with a crank pin in the wheel and extending at right angles to the said supporting means; a hollowr tool holder adapted to receive the crank-pin; means for rotating the holder; and means for feeding the saidl holder toward the support.
2. A machine of the type described-comprising, in combination, a. bed; a pair of lifting jacks carried by the bed; means for clamping upon the'jacks an axle with driving-wheels rigidly thereon; means for operating the jacks indecndently and together; a saddle supported y the bed and slidable in the direction of the jacks; a hollow toolcarrying spindle rotatably supported in the saddle; means for feeding the saddle; and
means for rotating the spindle.
