This invention relates to an improved machine" for grinding the worn wheels of locomotives and cars, the primary object of the invention being to provide a more eflicient" and reliable machine of this character: either in a portable form suit able: for grinding: such wheels without removing them from the locomotives or cars, or in a stationary 'form' suitable for grinding such wheels whilerem'ove'd from the locomotives or cars.
Another importantobject of the invention is to provide a machine of the character indicated above capable of grinding a pair of wheels at a time on opposite sides of a locomotive or car.
. Other important objects-and advantageous fea turesof the invention will be apparent from the following description and the accompanying drawings, wherein, for illustration herein, a specific embodiment of the invention is set forth in detail.
1 In the drawings:
Figure 1 is an outboard end elevation showing the-machinepositioned to grind a car Wheel;
Figure 2- is a fragmentary side elevation looking from right to left in Figure 1;
. Figure 3 is a top panview of Figures 1 and. 2';
Figure 4 is a top plan view of the wheel-elevatmg means;
Figure 5. is a general schematic top plan view showing the machine arranged to simultaneously grind a pair. of the wheels.
Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the numerals 6' designate companion rails supported on the ground '5' or other support, abovev which rails companion car or 1000- motive wheel'sB, a arepositioned and connected by an. axle 9,, journaledon. a spring bolster ill;
The illustrated machine, when used without removal of the wheels 8 from, a locomotive or car, contemplates the use of wheel cradles 14 which tunction to elevate the wheels 8 above the rails 6 and to rotate the wheels while being ground. Each cradle. [4 comprises a pair of similar, longitudi'nally-spaced boxes l having laterally-spaced depending portions [6 to. straddle the related rail, and rest upon the opposite flanges [.2 thereof, as indicated in Figure ,2, the, portions It being equipped with setscrews I! to engage therail web [8, below itshead lZ. Thedepending portions have lateral enlargements 19 through which longitudinal bolts 20 extend along opposite sides of the. rail Band which are equipped with nuts 21' on their opposite ends to draw the boxes [5 to- 5 Claims. (Cl. 51-104) ward each other. Laterally-spaced upper portions 22 of the boxes are traversed by axles 23' carrying rollers 24 between the portions 22 tosupportaby engage the rim of the car wheel 8. One
pair of the axles 23 is operatively connected by a shaft 25, as shown in Figure 5, having a pulley,
26 thereon over which is trained a belt 21 driven by the electric motor 28, whereby the pair of wheels 8 is rotated together at the same speed, With the cradles [4 in place with the rollers 24 fore and aft of the wheels 8, the nuts 2| are tightened to bring the rollers closer together and thereby elevate the wheels above the rails so that the wheels can be rotated by the motor 28. Cur rent for operating the'motor 28' can be obtained fromany suitable source, such as the generator of a Diesel locomotive when the machine is usedto grind wheels of such a locomotive.
The motor 28 is mounted on a flat bar 29 laid across the rails 6' and having bolts 30 at its opposite ends operating clamp elements 3| arranged to engage under the outer sides of the rail heads I2, as indicated in Figure 1, to hold the bar 29 in;
place with the motor belt 21 tight.
The grinding component of the illustrated machine comprises a frame composed of a fiat, transversely-elongated bar 32, long enough to extend beyond the outboard sides of the rails 6 when laid thereon, and having pairs of spaced depending lugs 33 to engage opposite sides of the rails, as shown in Figure 2. Each end of the frame bar 32 has a vertical bracket plate 34 extending above and below the bar 32, having bolts 35 and 36 through its upper and lower portions,
respectively, which extend through the adjacent side wall 31 of a box-like component 38 having a horizontal top wall 39 and an open bottom.v Between the top Wall 39 and the lower end of the component 38 is a heavy plate 49 formed in its under side with a concave recess 4|, larger in diameter than a large ball bearing 42 which rests in a similar concavity 43 formed in the upper surface of a plate 44 placed upon a supporting block 45 resting upon the rail-supporting surface; 1 outside the adjacent rail 6. The thickness of the block 45 is chosen to support the frame bar 32 above the rail head 12. The freedom provided the ball bearing 42 to roll slightly in any direction or to move universally in the recesses 4i and l}! enables the frame to move relative to the rails 6 by the eccentric motion-of out-of-round Wheels while being ground without upsetting the accuracy and concentricity of the wheel-grinding action of the machine.
Bolted, as indicated at 4 6, to the top plate 39 of each frame component 38 is the lower bed plate 41 having a tenon slide portion 48 with which is conformably engaged the similarly-shaped channel 49 of the intermediate or transverse bed plate 50. A traversing screw is arranged through the lower bed plate 41 and engaged in a conventional manner (not shown) with the intermediate bed plate 50, whereby rotation of the handle 52 can move the intermediate bed plate 50 in an inboard or an outboard direction. Similarly keyed on the intermediate bed plate 53 for longitudinal movement atright angles to the intermediate bed plate is the upper bed plate 53. A traversing screw 54 is arranged through the intermediate bed plate 50 and connected to the upper bed plate 53 in a conventional manner (not shown) and the screw 54 has an operating handle 55 for producing movement toward and away from the wheel 8 to be ground.
Bolted on the top of the upper bed plate 55, as indicated at 55, is another and more powerful electric motor 51 whose shaft 58 projects in an inboard direction and has mounted thereon the grinding wheel 59, which, with the motor 51 running, is adapted to be moved across the rim of the wheel 8 in contact therewith by manipulation of the traversing screw handles 52 and 55.
The handles 52 and 55 are manipulated to cause a guide roller 55 on a depending support 6! on the wheel side of the frame component 38 to follow a guide opening 52 in a horizontal guide plate 63 projecting from the same side of the component 38, whereby the face of the wheel 3 will be correctly ground.
'Concentricity of the grinding action of the machine with respect to the center of the wheel axle 9 is obtained and maintained by means of a rigid arm 64 projecting upwardly at an acute angle from the lower part of the frame component 58 at the outboard end thereof, as indicated in Figures 1 and 3, and terminating at its upper end in a cylindrical head 65 traversed by a horizontal centering pin 65 on which is threaded a lock nut 56' for engaging the head 55, the centering pin having a point on its inboard end to engage in a hole 58 provided in the end of the wheel axle 9.
With the centering pins 86 engaged in the holes in the ends of the car wheel axle 9 and the wheels 8 supported by the cradles [4 being rotated by the motor 28 and the grinding wheels 59 rotated in engagement with the rims of the wheels, any eccentricity or out-of-roundness of the wheel of wheels will cause the frame of the machine to rock on the ball bearings 42 without losing concentricity with respect to the wheel axle, and the grinding wheels 59 will operate continuously upon the rims of the wheels 8 at the same distance from the centers of the wheels, thereby accurately truing the wheels.
Where existing obstructions around the wheels 8 make desirable the placing of the grinding motor assemblies between the wheels 8 rather than in the outboard relation above described, the intermediate bed plates 50 can be taken off the lower bed plates 41 and placed instead upon an alternate bed plate extending continuously across the frame bar 32 between the rails 5, as shown in Figures 3 and 5, with the motors 51 and grinding wheels 59 in reversed positions, with extensions H connected to the transverse traversing screws.
