N. D. LEVIN Filed May 29, 1930 Patented Apr. 19, 1932 rsa SATES ArENr OFFICE 1 NILS D. LEVIN, OF COLUMBUS, OHIO, ASSIGNOR TO THE JEFFREY MANUFACTURING COMPANY, OF COLUMBUSQOHIO, A CORPORATION OF OHIO EQUALIZING Application. filed May 29,
The present invention relates toequalizing mechanism for vehicles, and is designed to maintain proper and uniform distribution of, the load when such vehicle is moving over annneven road bed or trackway.
It is here disclosed in connection with a mine locomotive of not unusual type, but this is illustrative only, and in no sense restrictiveof the invention. This example is adopted to illustrate the invention, for the reason that mine trackways are notoriously uneven, and it becomes'of primary importance toprovide equalizing mechanism which will compensate for drop and lift, and relative movements between the load carrying frame and the supporting wheels and axles, on opposite sides of the vehicle.
The purpose of the present invention is to provide an equalizing mechanism in which the relative movements of the frame and wheel and axle of either side of the vehicle will be positively and-effectively transmitted to the other side with compensating or equallizing effect, the arrangement being such that there is no backlash or lost motion by reason of the connections designed to produce the equalizing effect.
In the drawings herewith Figure 1 is a view in side elevation of a mine locomotive,
Figure 2 is a view of a section of a side frame of a locomotive, showing the wheel and axle, the axle box and its associated parts, and the equalizing mechanism,
Figure 3 is a view substantially on the line 33 of Figure 2, looking in the direction of the arrows.
Referring to the drawings by numbers, like parts indicating like parts in the several views, 10 indicates a locomotive side frame which is supported upon the usual wheels 11 connected by axles 12.
It is usual to provide, in a four-wheeled vehicle of the type shown, equalizing mechanism for but one of the axles, it having been MECHANISM 1930; Serial No. 457,383.
The axle 12 is mounted in any suitable axle box 13 carried in a guideway 11 in the side frame 10 and capable of vertical movement I in the guideway, the load being resiliently supported, as by springs 15, which engage an abutment 16 mounted above the axle box, as here shown, and being guided in the guideway 14, in which it may rise and fall. The abutment 16 engages a cam 'p roj (action on the equalizing lever 17, pivotally connected with the side frame 10-on thein'side of the frame, as at 18 shown in Figure 2. The equalizing lever 17 carries at its free end a thrust bar 19, which, as here shown, is pivotally connected to the lever 17 so as to be freely pendant, said thrust bar being provided with rack teeth designed to engage a pinion 20 mounted on a shaft 21 which is journalled on the side frame at 22 in any suitable manner. The thrust bar 19 has an abutment 23, here shown in the form" of a roller, secured to the side frame so as to form anti-friction means for holding the rack of the thrust bar 19 always in engagement with the pinion 20 of the shaft 21.
i The shaft 21 forms a torsion member between the two equalizing mechanisms, which,
the axle box and the moving parts as shown in Figure 2, but with the transmitting parts disposed in'opposite relation, as will be clear 17 and, by means of the thrust bar 19, positively imparted to the shaft or torsion member 21, through the pinion which engages the rack on the thrust bar. This Will effect rotation of the shaft 21, and the pinion at the opposite end of the shaft Will at once impart positive movements in an opposite direction to the thrust bar 19 atthe other end of the axle, which opposite movement will be trans mitted to the equalizing lever 17 and its associated parts so as to bring about a substantially uniform distribution of the load.
The advantage of this construction is that the action of the parts is positive, there being no flexible or loose connections Which permit backlash or play, or which are likely to become stretched in use and require frequent take-ups.
Mechanical variations of the mechanism here shown may, of course, be made Without departing from the range of my invention.
