, App1ication filed August 15,, 19,52 3. Serial No 357,562.
The objects of the invention are to pro- .vide an improved ,machine' for grinding the hardened steel tires of locomotive drive wheels, ,without removing them fromv the wheels, thus avoiding the labor of removing thetires from the wheels, and of separately turning them in a lathe, and also eliminates the process of heating the tires to expand them so that they can be removed from the wheels and of afterwards reheating them to put them back in place.
WVit-h the use of this device grinding discs revolving in onedirection maybe applied to the wheels revolving upon their own axles in another direction, and hence the circumferences of the tires will be ground perfectly true, and all inequalities in the surface removed with perfect precision.
In using this device the locomotives are raised above the track, and the wheels are revolved upon the grinding discs with the power of the locomotive, but does not require the removal of the guide bars, or side rods or other engine parts or heating the tires. Also after the tires have been re.- moved from the wheels, and turned upon a lathe the reheating and driving them upon the wheels may destroy the perfect form of the circumference.
The invent-ion comprises the combination and arrangement with a pair of carriages rigidly connected across the engine tracks, a shaft thereon upon which a pair of spaced grinding discs are secured, means for automatically reciprocating the shaft, and means for separately feeding the grinders in the direction of their diameters against the tires, and means for revolving the shaft.
The invention is hereinafter more fully described, illustrated in the accompanying drawings and specifically pointed out in the claims.
In the accompanying an end elevation of the device. Fig. 2 is a transverse central section thereof. Fig. 3 is a rear elevation thereof, and Fig. 4 is a plan thereof. I
In these views 1, 1, are the driving wheels, 2, 2 are the hardened tires. 3, 3, are the track rails which run over the pit 4. 5, 5, are spaced bases mounted upon the tracks and connected together in pairs across the track by means of rigid bars 6, 6.
drawings Fig. 1 1s Upon thesebases rollers 7, are mounted (and the car wheels rest and revolve upon these rollers while being ground.
. Bolts 8, S, secure thesefbases to the rails.
Qppo'site carriages 9, 9, connected together across the track by meansofthe rigid bar 10 are adjustably secured to'the rails by means of bolts 11, 11.
These carriages are positioned wherever they are most convenient for use in applying the grinding discs to the tires and are shown in the figures between the engine wheels.
Upon these carriages the shaft 12 is mounted in adjustable hearing blocks, 13, 13, which move radially towards and from the center of the engine wheel being operated upon in guide bearings, 14, 14. Upon the shaft 12,, a pulley 15 is mounted which may be rotated by means of a belt 16 driven by apulley 17 .upon the shaft of an electric motor 18 in the pit. This shaft is oscillated automatically by means of the rock arm, 18, slotted at 19, the pin 20 on the shaft,
or'on an adjustable sleeve 21 thereon, and a connecting rod 22 which connects the arm with the crank pin 23 upon a worm gear 24 which is rotated by means of the worm 25 upon the aforesaid shaft.
The grinding discs 26, 26 are mounted adjacent to the ends of the shaft by means of clamping nuts 27, and washers 28, and
revolve and oscillate laterally therewith.
The radial adjustments for the shaft and discs are separately, and manually accomplished by means screw shafts, 29, 29 which operate in the shaft bearing blocks, 13, 13, and are rotated by means of bevel gears 30, and 31 respectively, and the operating shafts 32, 32 hearing hand wheels 33, 33.
Springs 34, 34 may be employed if desired to permit the disc bearing blocks to yield to unexpected projections upon the circumferences of the tires, and thus prevent fracturing the discs. These springs may be as powerful as may be desired.
These springs are mounted upon the radial shafts 29' between collars 35, thereon, and the end bearings 36.
Variations in the form and structure of the parts may be made within the scope of the claims.
of the radially inclined Having described the invention, what I claim new, and desire to secure by Letters Patent, is:
1. In a device for grinding the tires of locomotive wheels, the combination with the track rails, of bases detachably secured thereto, rollers mounted on said bases, upon which said Wheels rest, carriages detachably secured to said rails adjacent to the tires to be ground, bearing blocks radially adjustable in said carriages in relation to said wheels to be ground, a transverse'shaft mounted in said bearing blocks, means operated by the rotation of said shaft for giving an oscillating movement thereto, grinding discs adjacent to the ends of said shaft, radial screws in said carriages for adjusting said bearing blocks, bevel gears for rotating said screws, outer bearings for said screws, and compression springs for resiliently supporting said bearings.
2.'In a device for the purpose set forth, a transverse rotatable shaft and grinding discs thereon, spaced carriages adjacent to the wheels to be ground, a transverse rigid member connecting said carriages, a Worm on said shaft, a worm Wheel mounted upon said rigid connecting member, a rock arm pivoted on said rigid connecting shaft, and a link connecting said shaft and an eccentric point on said Worm wheel.
In testimony whereof, I hereunto set my hand this 2 day of July, 1923.
WILLIAM E. oooNEY.
