13 Claims.

This invention relates to machines for turning inside or outside journals of a wheel set for a locomotive and for quartering and turning the crankpins of the driving wheel sets.

Various machines have heretofore been produced for accomplishing the various operations of journal turning, quartering and pin turning of wheel sets for locomotives. The machines have either been individual machines for accomplishing the various operations or there have been certain disadvantages connected with a single machine for accomplishing these various operations.

It is an object of this invention to provide a single machine which is capable of performing all of the necessary operations of journal turning, quartering and pin turning with greater safety and less inconvenience than has heretofore been capable of performance upon combination machines.

Another object of the invention is to provide a combination machine wherein the quartering and pin turning operations of the wheel set can be accomplished with the counterweights of the wheel set positioned in their least dangerous position, and for subsequently turning the journals on the wheel set.

It is another object of the invention to provide a combination machine for journal turning and quartering a wheel set wherein the counter-balances of the wheel set are positioned in a manner that the effective center of gravity is in substantial vertical alignment with the supporting spindles for the wheel set, and which is capable of turning the journals on the wheel set without removing the same from the machine after the quartering operation.

It is another object of the invention to provide a method for performing the quartering, pin turning and journal turning operations of a wheel set in a manner which will produce the greatest safety of operation of the machine.

It is another object of the invention to provide a method for positioning a wheel set within a metal turning machine in a manner that the wheel set is established therein in its safest position, and for quartering the wheel set while in said position, and to provide for subsequent balancing of the wheel set when turning the journals thereon. I

It is another object of the invention to provide an improved apparatus for hoisting the wheel set into position in alignment with the spindles of the machine.

It is another object of the invention to provide an improved apparatus for holding the same against rotation when the wheel set is supported by the spindles of the machine.

It is another object of the invention to provide a clamping apparatus upon a metal turning machine for locomotive wheel sets which will not displace the parallelism of the wheels while being quartered, or during pin turning.

It is still a further object of the invention to provide an improved'adjusting device for rotationally positioning the wheel set in an accurate manner for the quartering operation, and for pin turning.

It is still a further object of the invention to provide a clamping device for a wheel set which isadjustable in a manner that wheels of varying diameters can be secured against rotation.

Further objects and advantages will become apparent from the following description and from the figures in the drawings.

In this invention the machine is adapted to perform several operations upon a wheel set for a locomotive when producing and finishing the same. The various operations of turning the journals on a whel set, of quartering the same, and of turning the crank pins thereon have the center of gravity of the counterweights of the wheel set is below the turning centers of the machine, and substantiallyfin. verticalalign the brackets 30 and Si.

The feed rod 3Ia is drivingly connected to a power driven gear 320., drivingly connected with the gearing in the head stock I5, by means of an interconnecting shaft 33a. A speed change mechanism 34a is interposed between the drive gear 32a and the feed rod 3Ia. The bracket 30 supports the tool carriages 32 when turning the inside journals of a wheel set while the bracket 3| supports a carriage 32 when turning an outside journal of a Wheel set.

ment therewith. This arrangement provides the greatest safety of position for a wheel set when in a turning machine for thejquarter and turning operations. The ma'cnme'alse proviaes' for counter-balancing the unbalanced weight of the wheel set when turning the journals "there on, whereby a machine having the greatestsafety conveniences is provided.

In this invention .the machine consists of a bed ID which is supported upona suitableconcrete base- I I, and is adjusted to alevel position by means of the awedgeblocks I2. A headstock I 5 is positioned upon. the ibed.,I- and is adapted-for longitudinal movement along the bed ID to permit adjustment of the live, spindle I6 thereof, with respect a Wheel set; An electric motor I50. is mounted adjacent one side of the head stock I having thedrive shaft extendinginto the same for driving suitable mechanism positioned within the head stock I5 for rotating the live-spindle I6, which mechanism is well known in the art. .A face plate I! is adapted to. be mounted upon the live spindle I6 for carrying counter-weights (not shown). for counter-balancing -the unbalanced weight ,of the .wheel set when turning the journals thereon. -A,suitable;dog -is provided for interconnecting the face plate with the wheel set for drivingly engaging the wheel set-when turningthe journals., j j W The live spindle l6 is cQnneCted by -suitable mechanism with a hand wheel- -I9 which hand wheel advances the turning center of-thespindle into engagement with the wheelset when positioned in the machine. Therejs also provideda suitable mechanism engaged by operationof the clutch lever 29 which engages mechanism interconnecting the hand wheel; 2 I, with; the spindle It in order to rotate the same and the face plate I I1 for bringing the face plate into a particular po t when sin he ma hineiw u rt r n a wheel set. A locking device 22 is mounted upon the head stock I5 and engagesthe faceplate ll tolgck the same in position when quartering a wheel set v .E

A tail stock 25 is positioned upon the opposite end of the machinefrom the headstock I5; A

supporting cente'rlorspindle is suitably positioned within the tail stock l25 forengaging a wheel set, which spindle is advanced or retracted by suitable mechanism; controlled by means of the hand wheel 2'1. The tail stock is movable longitudinally along the bedfl] and is locked in position. upon thebed III by means of the -'clamp ing device 28. The head stock I5 is secured in its position upon the bed I0 by .a similar clamping device 29. a

A p of carriage bracke s .30 nd 1 3.1 are secured to the bed [Hand are adapted to support a plurality of tool carriages 3,2. Thetool carriages 32 are drivingly 'connected with a power driven rod 32a,-which is connected bysuitable power driven mechanism with the feedrod- 3Ia Each'of the power driven carriages 32 sup- 'p'ort across slide 33 upon which a tool support 34 is positioned. The cross slide 33 may also be j power driven or hand driven for transverse movement'of the tool holder or support 34.

A' wheel set 40 comprising an axle 4| and a pair of Wheels 42 is adapted to be positioned between the live spindle I6 positioned upon the headstock I5 and the turning center positioned upon the tail stock 25.

When a wheel set is being turned there is considerable unbalanced weight upon the set due to the counter-balances provided thereon. for balancing the connecting rod and operating mechanisms of a locomotive drive device. In order to balance this unbalanced weight of the wheel set when turning the journals thereon, a counterbalance weight is positioned upon the face plate for operating the carriageslongitudinallyalong 75 .I I wherebythe rotation of the wheel set is smooth and is without vibration. The tool carriages 32 are suitably adjusted with a tool 45 positioned within the tool holder 34 for removing the desired material from the axle M of the wheel set.

" The tool carriages are power driven longitudinally along the axle 4 I for removing material therefrom in the normal manner of lathe turnin In order to provide for quartering the Wheel set 40, a quartering device is mounted upon the head stockI5 while a quartering device 60 is positioned adjacent th tail stock 25. The quartering attachment 50 is mounted directly upon the head stock I5 and consists of a driving motor 5| which provides power through the belt 52 into a gear housing 53. Suitable gearing is provided within tht housing 53 for driving a boring spindle 54. The boring spindle 54 is arranged parallel with the axis of the live spindle I6, and is disposed in a plane passing through the axis of thespindle I6 which is arranged at an angle of 45 from a vertical plane passing through the axis of the spindle I6. The boring spindle 54 is thus positioned abov the axis of the spindle I5 and at an accurate 45 angle therefrom. V The quartering device 50 is carried upon a support bracket 55 which has an angularlyinclinedface 56 upon which the quartering device is supported. The quartering device 50 is suitably. arranged to bemoved radially with respect the axis of the spindle 'I 6 in order to position the boring spindle 54 at different radial distances from the spindle I6. A suitable adjusting screw 5l is provided for making the radial adjustment of the position of the quartering device 50. A hand wheel 58 provides means whereby a suitable mechanism, engaging the boring spindle 54, causes the spindle to be moved longitudinally by means of the hand wheel 53. The boring spindle 54 is also adapted to be power driven by the motor 5| through a suitable train of gears withinthe housing 53. The quartering attachment 5!? is supported upon a bracket BI secured to the bed 15, which has an angular face 62. The angular face 62 provides means upon which a support 63 canbe moved radially by means of a suitable adjusting screw 64. The support 63 carries a suitable gear box 65 which interconnects an electric motor 66 with the spindle 61 for power driving the same. A hand wheel 68 also engages mechanism with the gear box 65 for manually advancing or retracting the spindle 61.

The spindle 61 is of the type known to the trade as a pot type spindle. The spindle 61 consists of a hollow cylindrical member suitably bearinged in the quartering attachment 60 and is driven by the electric motor 66. The forward edge of the cylindrical member or spindle 61 is provided with T slots 69 in tht face thereof by which a boring bar is secured thereto when quartering a wheel set, or for securing a turning tool thereto when turning the pins on a wheel set.

The spindle 61 is parallel with the turning center 26, and is disposed in a plane extending through the axis of the center 26 that is arranged at an angle of 45 to a verticalplane extending through the turning center 26.

It is thus seen that the boring spindles 61 and 54 are arranged above the axis of the live spindle I6 and the turning center 26, and that planes passing through the axes of the boring spindles 61 and 54, and the axes of the live spindle I 6 and the turning center 26 form an angle of 90 with respect to one another, since the axis of each spindle 61 and 54 is disposed in a plane extending through the respective spindles and the axes of spindle centers I6 and 26 that form an angle of 45 with a vertical plane extending through the spindle centers I6 and 26.

The wheel set 40 is arranged to have the pin bores 1|, located 90 apart in order to provide a lead of one wheel over the other. The counterweights (Fig. 10), are provided for counterbalancing the weight of the pin, th connecting rod and other operating mechanisms, and are thus located 180 from the pin bores 1|. It may thus be seen that since the boring spindles 54 and 61 ar arranged above the axes of the turning centers I6 and 26 that the major portion of the counterweights 10 will be arranged below the turning centers I6 and 26 and that a plane passing through the centers of the counterweight sections and the wheel centers will be displaced 45 angularly from the vertical plane through the wheel centers when the wheel set 40 is supported between the turning centers. This arrangement thereby provides the safest position of the wheel set when in a machine for quartering the same since there is no tendency toward torque movement of the wheel set which would have a tendency to throw the set should an accident occur, the eifectiv center of gravity of the wheel set being in substantial vertical alignment with the axes of the turning centers 16 and 26.

The boring spindles 54 and 61 may be operated simultaneously or successively depending upon the will of the operator since each device is under separate power. It is to be understood of course that the boring spindles 54 and 61 engage suitable mechanism within the gear housings 53 and 65 respectively for causing advancement of a boring tool through the pin bores 1|. The operation may be carried out manually by means of the hand wheels provided on the respective quartering devices 50 and 60.

When positioning a wheel set within the combined machine for quartering, journal turning or pin turning, the wheel set 40 is elevated into position in axial alignment withthe turning centers by means of tread jacks 80, which are positioned under each of the wheels of the wheel set 40. Since the center of gravity of the wheel set 40 is normally in its lowest position, as previously described, it may be seen that the wheel set 40 can be supported directly upon the tread jacks without further support whereby the axle -4| of the wheel set can easily bev brought into alignment with the turning centers I6 and 26. The turning centers I6 and 26 are then brought into engagement with the axle 4| to properly and accurately align the wheel set 40 with respect the turning axis of the machine.

Either the quartering operation or the journal turning operation can then be performed. If the journal turning operation is to be first performed the face plate I1 is counter-balanced as heretofore mentioned and the tool carriages 32 operated in conventional'manner to remove excess material from the journals of the wheel set. Without further alteration of the machine, the wheel set can be quartered by bringing the counterebalances thereof into their lowermost position therebyaligning the boring spindles with the roughly cast pin bores 1| in the wheel set 40.

In order to accurately align the pin bores 1| with respect the boring spindles 54 and 61, an adjusting mechanism is provided. This mechanism consists of a rotatable rod 86 which threadedly engages a collar 81. The collar 81 is pivotally mounted upon an arm 89 which is secured to the bed I0 by means of the bolts 90. The opposite end of the rod 86 extends through a c clamp 9| which is provided with set screws .92 in threaded engagement with the arms of the C clamp 0|. The set screws 92 are in axial alignment and are adapted to engage the edge of the wheel 42 as indicated at 93 (Fig. 9) whereby the C clamp 9| is provided with a pivotal engagement with'the wheel 42. The rod 86 is provided with collars 94 positioned on either side of the C bracket '9I to position the same upon the rod 86. The upper end of the rod 86 is provided with a suitable rectangular or square shape which can be engaged by a wrench for rotating the rod 86 whereby the length thereof between the pivots 88 and 92 can be altered.

The wheel set 40 can thus be adjusted rotatably by means of the adjusting device 85 in order to accurately align the roughly cast pin bores H with respect the boring spindles 54 and 61. Upon making the above mentioned alignment the wheel set 40 is clamped against rotation by means of a clamping device I00.

A clamping device I00 is provided for each of the wheels 42 of the wheel set. This clamping device consists of a supporting bracket |0I secured to the bed I0 by means of suitable bolts I02. The supporting bracket IOI has a pair of parallel T slots I03 positioned in the face I04 thereof. A bracket I05 is carried upon the face I04 by means of bolts I06 which extend through the bracket I05, and have the heads thereof engaging the T slots I03. The bolts I06 have suitable nuts I01 in threaded engagement with the ends thereof, for securing the bracket I05 upon the face I04 of the support IIII. A threaded rod 0 is supported by means of a bracket III secured to the support I0| by 'means of the bolt H2. The threaded rod 0 is carried upon the bracket III by means of spacing collars H3. The rod H0 is in threaded engagement with an ear 4 extending from the bracket I05 whereby the bracket can be moved vertically with respect the support IOI by rotation of the rod, III].

The bracket I05 consists of two parts, I05A- and 105B, for'minga split-bearing around a' trans versely extended shaft II5. A binding screw I I6 extends through the flanges I I? of the split bear ing-halves 105A and I'IJ5B, whereby the. bearing halves are :caused to bind upon theshaft 'I I5. A

c clamp I25 is pivotally mounted. upon the shaft I I5 as at I20, and is provided with a binding "set screw I2I.in the opposite end of the clam Upon .making the final accurate adjustment of the wheel set with-respect the boring spindles 54 =and61. by means of the adjusting device 85, the'shaft'I-I5of the clamp means I is brought into 'engagement with the innerv face of the wheel 42. The binding screw is thentightened to retainthe shaft H in position'in engagement with theface of the wheel42. It .is to be understood of course that the shaft 5' has beenbrought intoitheproperahorizontal position with respect the..wheel 42 by means of the threaded. rod "I II] I which has elevated the bracket I05 to the-proper position. :The. bracket I05 has been securedto the support IIJI by means of .the nuts and'bolts I01. and I05 respectively. The C clamp 125318 then brought adjacent the edge of the-wheel 42 andsthe binding bolt drawn tightly against the outer 1 face; of the' wheel, whereby the wheel is secured against rotation. It may be seen that the clamping devicesQIM adjust themselves to thewheel spacing, rather than forcing the. Wheels to'adjust themselves to the clamp spacing. This arrangement provides an apparatus which preventsany springing of the wheelsfland thereby permits more accurate boring or the pin bores II of thewh'eel set 40, andmore accurate pin turning.

iIhe.-'wheel 'set 49. is now in condition to be quartered. The boring spindles .54 and 51 are suitablyiiadvanced'by the machine, or by-rnanual. means, for causing the desired boring or quartering. operation/whereby the pin:bores .II are accurately spaced at a 90 angle from each other.z.'..".-

:- Inzthe newer type wheel sets for locomotives thebearing housings'are attached prior tothe time. the wheel .set is quartered. This is particularly true in those i'nstanceswhere, ball or roller bearings are installed upon ,theaxle 4I 'of t'hewheel set.- The wheel clamps I00, if made high 'enou'gh..to.:.permit .sufiicient vertical adjustment of the'C clamps to takecareofsmall diameter wheels interfere with the bearing housings on large diameter. wheels when positioned in the machine. Hence, whenturning or quarteri'ng .smallsdiarneter wheels the clamping device I00 must be elevated sufficiently to permit the effective use: of the clamp I25. .A spacer block I30 ls zthlls provided between the bracket III and th'esupport 'IUI (Fig. 8). In this instance the-bracket IN is bolted to the spacer "block I39 byzmean's of the. bolt I IZA, while the spacer block 130 is secured'to the support I01 by" rneans. of .a .flange I3! positioned thereon engaging a flange I32 provided on the support 'IBI (Fig. 4). Asuitable bolt I33 extends' through the flanges I3I .and'i32 to. secure the same togetherp I u Asheretoforementioned the wheel set '49 is adapted to be. elevated into position in alignment with the-turning centers I6 and 26, by means of --a tread jack rather than by means of an axle jack as has been heretofore common practice in'the art. The use of tread jacks has been required due to thepositioning of. bearing housings u'po'n the wheelsets prior to the time they are quartered. The arrangement of .positioning the wheel set 40 within themachine with thecenter of .gra'vityin vertical alignment with the axes of-the turning centers I6 and 26 provides a particularlyadvantageous arrangement for the used of'tread jacks, since the wheel set will balance itself upon the jack.

The jack as provided in this invention consists ofa shoe I50 which is secured upon the endsofathreaded rod I5I. ,Therod I5I carries a nut I52 which is .positioned within a supporting housing I53 upon a'thrust bearing I54. The support housing. I53 is carriedwithin a recess I54A providedin the bed H) of the machine. The nut I52 has a spiral gear I551secured thereon, which is in engagement with a spiral gear I56. The gear I55 is in turn in communication with an operating shaft I5'I which extends exteriorly of the bed I0 and is provided with a wrench connection. I.58 on the exterior end thereof. Rotation. of the shaft I57. will cause the nut I52 to be rotated'by means of the spiral gears I55 and I56 whereby the threaded rod I5I is raised or lowered to carry the wheel set thereby.

The quartering and journal turning operations have heretofore been described. The crank pin turning operation can also be performed upon this combined machine of my invention. Itis of courseunderstood that after the qua'rtering and journal turning operations the wheel set 40 is removed from the machine in order to permit the placement of crank. pins within the pin bores 75. After this operation, the wheel set 40 is returned to the combined machine of my invene tion. The wheel set is positioned upon the tread jacks 8B and hoisted into positionwith the axis of the Wheel set in alignment with. the axesof the, turning centers. The .clamping devices I09 are again positioned in operative relation with the wheels 42 of the wheel set 40 to prevent rotation of the wheel set.- The wheel set 40 is adjusted .rotat'ably by meansv of the adjusting device in order to properlyv align a crankpin with respectto the axis of the boring spindlefiI. :Asheretofore described, the boring spindle 61 is known to the trade asa pot type spindle. A suitable turning tool is secured within the spindle 61 by Suitable fastening means engaging the T slots 69. The boring spindle 61 is then advanced either automatically or manually by the quartering attachment 65 so as to turn thesurface of the crank pin in alignment therewith. .Since the machine is provided withonly one potitype spindle 61, the wheel set is required to be repositioned so as to bring the .crank; -pin of the opposite wheel'into alignment with the spindle 57. While the machine as disclosed in the drawings requires two positionings of the wheel set 40 in' order-to turn both crank pins thereon, it may readily be understood that both of the boring spindles 51 and 54 could be of the fpot type.

There are' certain disadvantages however in making the boring'spindle 54 of a pot type spindlesince the spindle 54 is required to extend through the face plate I'l when quartering the wheel set or when the spindle 54 is to be used for pin turning. The normal procedur is to permit the boring spindle 54'to extend through an opening (not showing-in the face plate 11, the face plate I! of course, being brought toa predeterminedposition by operation ofthe hand wheel 21 in order to permit "the boring spindle 54 to extend through the opening provided in the face plate l1.

It may thus be seen that my combined machine provides all of the necessary operations for finishing the journals, crank pins and for quartering a wheel set, which machine is flexible for working upon various size Wheel sets, and which positions the wheel set in the machine in a manner which produces the least danger to a workman engaged thereupon.

While the apparatus herein disclosed constitutes the preferred form of the invention yet there are other forms which will fall within the scope of my invention and I do not wish to be limited by th specific disclosure herein described.
