1 Claim. (Cl. 51 -179) This invention relates to a machine for-grinding the wheels of locomotives and railroad cars.

It is aimed to provide a readily portable :structure which may be applied to a pair of track rails and fastened thereto removably and which carries one or more grinding wheels for grinding engagement with the locomotive or car wheels,

l5 become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure 1 is a view showing my improvements in elevation, partly broken away, attached to track rails and in operative relation to locomotive or car wheels;

Figure 2 is a plan View of the parts of Figure 1;

Figure 3 is an edge elevation of the parts of Figure 1;

Figure 4 is an enlarged elevation, partly broken away, particularly of one of the grinding units,

and

Figure 5 is a vertical section taken on the plane of line 55 of Figure 4.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, designates a supporting bar or beam,

5 preferably of channel or angle form in cross section, the same also preferably having webs H welded thereto to reinforce the same. The support 10 and parts mounted thereby are portable and are shown detachably fastened rigidly to a 40 pair of track rails l2. To this end, bracket 13 and M are carried by the support 10, the former being welded thereto and the latter preferably being adjustable and secured to the bar by means of a bolt [5. Such brackets 45 engage the inner faces of the rails as at the ball and portions of the web, as shown. In addition, lugs 16 are welded or otherwise rigidly fastened to the support In and depend from the same. Clamping bolts l1 are screw threaded to the lugs 50 16 and bear against the webs of the rails 12 and thereby removably and rigidly bear against the webs of the rails l2. Reinforcing webs I8 preferably extend outwardly from the lugs l6 between the pairs of bolts l1 of each lug I6.

55 Brackets or shelves generally of angle form are 'tical flange or wall of.

l3 and I LpreferabIy employed at 19, preferably-welded to the verthe support l0 and'they preferably have reinforcing webs as at 2 0, -welded in place. Each bracket 19 has a horizontal wall 2| on which a bedplate 22 is rigidly mounted as by means of welding.

Each bedplate 22 has a dovetail portion 23 extending transversely of the track rails l2 and slidably engaged by a dovetail recess or groove 24 of a laterally adjustable plate 25. Such plates 25 have dovetail recesses 26 extending longitudinally relatively to the rails l2 and slidably engaged by a plate 21, having a dovetail portion 28 disposed in the groove 26 and movable longitudinally with respect to the rails.

On the plate 21, motors 29 are carried, being electric motors, air driven or of any other approved type whose driven shafts 30, carry emery or other grinding wheels as at 3|.

Each plate 25 has a front or vertical wall 32 integral with it in which a short shaft 33 is journaled and operable by a knob 34 thereon. Shaft 33 carries a pinion 35 at the inner side thereof which is enmeshed with the teeth of a rack 36' depending from the plate 22 relatively close to the wall 32. Thus rotation of the knob 34 will rotate shaft 33 and cause pinion 35 and rack 36' to slide the plate 25 transversely with respect to the rails, accordingly carrying with it the plate 21, motor 29 and the grinding wheeL' A shaft 36 is journaled in the wall 32 and operable by a knob 31 thereon located above the knob 34. Shaft 36 is fastened against sliding movement by a collar or the like as at 38. Such shaft 36 as at 39 is provided with screw threads which are threaded to the plate 21 in any suitable manner so that when knob 31 is turned, shaft 36 will be rotated and the screw threads 29 and their engagement with the plate 21, will slide suchplate and motor and grinding wheel thereon in a direction longitudinally with respect to the rails. The construction is well adapted for grinding a pair of wheels at the same time, which wheels are suggested as at 40 and carried by an axle 4|. Said wheels may be on a locomotive or a car or any equivalent and the same are suitably jacked up with respect to the rails in any suitable manner and attention is called to the fact that it is unnecessary to remove the wheels or their axle from the locomotive or car in order to grind the peripheries of the wheels. Wheels 40 may of course be driven in any suitable manner. When they are on Diesel locomotives, the electric power of the locomotive is used to turn such wheels. When they are on steam locomotives, the steam power is used to turn such wheels. Any suitable means may be used to drive the wheels 40 when they are car wheels but I prefer to use the apparatus disclosed in my Patent No, 2,215,403 which issued from co-pending application Serial No. 300,266, filed October 19, 1939.

Attention is also called to the fact that the apparatus may be equipped with but a single motor 29 and grinding wheel and plate 22 and plate 27 in which event but one wheel 40 will have its periphery ground at a time, following which the parts mentioned will be transferred from one dovetail portion 23 to the other, and the second wheel 40 thereupon ground at its periphery.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:

Apparatus of the class described comprising a beam adapted for disposition transversely with respect to a pair of track rails, said beam having a horizontal wall to rest directly on the rails and a vertical wall rising therefrom, depending bracket means carried by the horizontal Wall to rigidly clamp said beam to the track rails, a grinding unit mounted on said beam for operation to grind the periphery of a wheel of rolling stock, said unit comprising a vertical wall disposed against and welded to the first mentioned vertical wall, a horizontal shelf integral with the last mentioned vertical wall extending forwardly therefrom at the top, webs connected to the shelf and last mentioned vertical wall, a bed plate disposed on said shelf having a depending front portion, a second plate slidably mounted on the bed plate, a third plate slidably mounted on the second plate for movement in a direction at a right angle thereto, said second plate having an upper part rising at the front thereof and a lower part in line therewith depending at the front thereof, means mounted by the lower part geared to said portion, means mounted by said upper part operable to slide the third plate, a motor mounted by the third plate, and grinding means rotatable by said motor on an axis parallel to the beam.
