4 Claims.
This invention relates to a machine or device for grinding and truing up the wheels of cars and locomotives.
It is particularly aimed to provide a construc- '5 tion which is portable so as to be capable of use wherever the locomotive or car is found, thus avoiding the necessity of placing the locomotive or car in the shop, and enabling the work to be more rapidly and expeditiously done.
The more specific objects and advantages will 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 in side elevation of my improved device;
Figure 2 is an end elevation taken at a right angle to Figure 1;
20 Figure 3 is a plan view of the machine;
Figure 4 is a section taken on the line 4-4 of Figure 3;
' Figure 5 is a section taken on the line 55 of Figure 3;
25 Figure 6 is a section taken on the line 66 of Figure 3;
Figure '7 is a section taken on the line 1-1 of Figure 2, and
Figure 8 is a detail section taken on the line 30 8-8 of Figure 3.
Referring specifically to the drawings wherein like reference characters designate like or similar parts, 10 generally designates a shoe, or frame which may be box-like or rectangular in plan 35 containing a pair of rollers I l and 12, disposed in the cavity 13 thereof and which rollers in turn engage the periphery of the wheel of a car or locomotive, such as is fragmentarily suggested at 14, in Figures 1 and 6. Said shoe is portable and 40 has separated depending side flanges 15, extending below a bottom wall or web I6. The web I5 is adapted to rest on top of the rail upon which adjacent wheel I4 travels, the same being suggested at I1. It will be noted that the flanges l5 are 45 disposed on opposite sides of the head or ball of the rail l1, thus mounting the shoe against displacement.
The supporting wheels II and I2 are rigid on shafts l8 and I9, suitably journaled in roller 50 bearings as at 20, mounted in the wall of the shoe Extending laterally from shoe l0, preferably integral therewith is a shelf or table 2| having an open casing 22 mounted thereon. Shaft l9 ex- 55 tends through and is journaled in the wall of the' casing. Another shaft 23 extends through and is journaled in the wall of casing 22 and such shafts l9 and 23 have intermeshing speed reducing gearing as at 24. Shaft 23 at 25, is detachably connected to the driven or powershaft 26 of an elec- 5 tric or other motor 27, supported on the shelf 2|.
The shoe to, at the top thereof, has a laterally extending supporting plate or shelf 28 which may be integral with it. Suitably rigidly mounted on plate 28 is a bedplate 29 having a depending 10 rack bar or flange 30. Said bedplate 29 has a dovetail rib 3| rising from the same fitted into a dovetail recess 32 of a slide 33. Slide 33 in cross section is of T-shape, having a vertical wall as at 34, extending above and below the slide proper. J ournal-ed in plate 34 below the rack 30 is a shaft 35, preferably operable by a knob 36. Keyed on shaft 35 is a pinion 31, which is enmeshed with the teeth of the rack 30. As a result, turning of the knob 36 will cause the pinion 31, by engagement with the teeth of rack 39, to move the slide 33 transversely with respect to the shoe l0 and rail l1.
On the upper surface of the slide 33 is a dovetail groove 38, extending at a right angle to the groove 32. A slidable carriage 39 is disposed on the slide 33, having a depending dovetail 40, oocupying the groove 38. Carriage 39 mounts an electric motor or the equivalent 4| which rotates its drive shaft 42, upon which a grinding wheel 43 is detachably mounted and which is engageable with the tread or periphery of the wheel l4. Carriage 39 is movable toward or away from the periphery of wheel l4 through the turning of a shaft 44 journaled in wall 34, the same having an operating knob 45. Said shaft 44 has a screw threaded portion 46, which is engaged with screw threads 41 in an opening of the carriage 39.
The device is preferably used in connected pairs, the two devices of the pairs being connected together by cross rods or bolts such as 48 and 49, detachably bolted thereto as at 50.
In order to engage the wheels 14 with the rollers II and I2 of the two shoes, the Wheels and rolling stock carrying them are raised by means of jacks or the like and the devices of the invention disposed beneath the wheels in supporting contact therewith. But one of such devices need have the reduction gear 22, motor 21 and similar parts, since the operation of motor 21, will drive 50 shaft l9 and through one of the rollers l2, will drive both Wheels I4 since as usual they rotate with the same axle. Both wheels l4 may be ground at the same time or they may be ground one at a time. In the latter event, but one of iii) the slides and parts carried thereby need be employed, since the same can be interchanged from the shelf 28 of one shoe ID to the shelf 28 of the other shoe Ill. The operation of the motor or motors 4! will operate the grinding wheel or wheels 43 and the latter in turn will grind the periphery of the wheel or Wheels l4. Each of the wheels 53, may be properly disposed with respect to the periphery of wheel l4 adjacent the same, through the adjustment of the knobs 36 and 45, since the slide and carriage and associated parts, enable movement of the grinding wheels in paths at right angles to each other.
Where a single device is used, that is one used as shown in the drawings, to grind but one wheel I4, the other wheel I4 is jacked or supported in a suitable manner, whereby the axis of the Wheel or wheels M will be level.
Various changes may be resorted to provided they fall within the spirit and scope of the invention.
