The transverse walls 1901: wide 15l5 of Figure 14. spokes 1%! merge with the inner wall 20 of the hol- I low rim'except that the wall 21 of the wide spoke nearest the counterbalance extends radially of the wheel to the outer periphery thereof, as indicated at 22, instead of merging with the inner edge of the counterbalance. The space 24 at the end of the counterbalance is left open to avoid the formation of a closed pocket diificult to mold and clean and side walls 23 are reinforced by beads 23a. The narrow spokes 16 are more flexible than the wider box section spokes 18 and, ac-

cordingly, more of the torque load from the hub will be carried by the box section spokes.

Figures 11 to 13 illustrate a, counterbalance structure in which'the casting forms a laterally opening pocket 25 adapted to have its opening closed by flat plate 26 which may be welded in place, as indicated at W. Preferably the inner I wall 27 has a flange 28 providing a widened sup- Additional weight material may be inserted in the spoke hollow through the opening in the periphery of the rim and this opening then plugged closed.

The pocket 25 may be filled with any desired material according to the weight necessary to balance the crank pin, connecting rod, etc., and

this material may be changed to accommodate various conditions. I

Figures 14 and 15 illustrate the combination of wide and narrow spokes merging with the counterbalance. Wide spoke 33 is hollow with its hollow portion extending into the counterbalance 34,

i .as indicated at 35. This arrangement provides for a counterbalance having its outer contour symmetrical about a center line which passes through the center of the wheel and the crank pin hub, but which provides for more weight on one side than the other so as to constitute an offset counter alance such as is provided on many wheels to balance the forces applied to the wheel. The hollows of narrow spokes 36extend through'the counterbalance to the periphery of the device.

Figures 16 to 18 illustrate a wheel center-made up of a plurality of wide hollow spokes 40 and 41 and near the periphery of the device spokes 40 are enlarged transversely of the plane of the device to provide pockets 42 having openings 43 in the lateral faces thereof through which lead or other suitable counterbalance forming material may be inserted. Plates 44 may be applied to the openings 43 and welded in place, as indicat ed at W. Preferably the pockets -of two adjacent spokes 40 are interconnected, as indicated at 45, and a spoke extension 46 braces the elongated counterbalance structure. This extension 46 is preferably provided with, a hollow 47'opening through the exterior of the device and through the inner wall 48 of the lateral enlargement of the spoke. a

The details of the driving wheel center may be varied in numerous other ways than those illustrated and described and I contemplate the exelusive use of such features of hollow spoke, rim, hub and counterbalance structure as come within the scope of my claims.

What is claimed is:

1. 'In a locomotive driving wheel center casting, v

receiving opening, a substantially solid metal counterblance spaced from'saicl hub, and hollow spokes extending between said hub and counterbalance, the hollows in said spokes being in communication with the annular hollow in said hub and extending through said counterbalance.

4. In a locomotive driving wheel center casting, a central mass of metal having an opening for receiving an axle and an opening for receiving a crank pin, there being a continuous hollow in said mass surrounding said openings, a substantially solid metal counterbalance, and hollow spokes between said central mass and said counterbalance with the spoke hollows opening into the hollow of said central mass and extending through said counterbalance.

5. In a locomotive driving wheel center casting, a hub, a counterbalance occupying a portion of the periphery of the wheel center, a hollow rim extending around the remainder of the wheel center between the ends of said counterbalance, and hollow spokes between said hub and counterbalance and between said hub and rim, the hollows of said first-mentioned spokes being continued through said counterbalance and the hollows of said second-mentioned spokes opening into the hollow of said rim.

6. In a locomotive driving wheel center, a hollow counterbalance, .and hollow spokes extending inwardly therefrom, the interiors of said counterbalance and spokes communicating with each other and there being a substantial opening from the hollow of said counterbalance to the exterior thereof. v

7. In a locomotive driving wheel center casting, a hub, a hollow counterbalance, and a hollow spoke extending radially of said hub, the wall of said spoke continuing through said counterbalance to the periphery of the device and the spoke hollowbeing enlarged inside said counterbalance to facilitate manufacture.

8. In a locomotive driving wheel center casting, a hub, a rim, a counterbalance extending inwardly from a part of said rim, relatively wide spokes between said hub and the remaining part of said rim and relatively narrow spokes between said hub and counterbalance.

9. A device as specified in claim 8 in which the counterbalance is of substantially solid construction and the narrow spokes have longitudinal hollows continued into the counterbalance to the outer periphery thereof.

10. A device as specified in claim 8 in which the spokes are of hollow formation and the hollows of the narrow spokes are continued through the counterbalance to the outer periphery thereof and the hollows of the widespokes extend throughout the length of the spokes, but terminate with the solid peripheral web of the rim.

11. In a locomotive driving wheel center, a hub, hollow spokes radiating therefrom, the portion of some of said spokes near the periphery of the device being enlarged transversely of the plane of the device to provide chambers for receivingmaterial to form a counterbalance.

12. A locomotive driving wheel center casting comprising a rim with a hollow part, a hollow spoke merging with said rim, and a counterbalance with an extremity on said rim adjacent said spoke and closing an end of the hollow part of said rim, the inner wall of said rim between said spoke and said counterbalance being omitted to form an open pocket and the adjacent wall of said spoke being continued to the periphery of said rim to compensate for said omissiom 13. In a locomotive driving wheel center integral casting, a substantially solid metal counterbalance part and a relatively narrow spoke part merging therewith, there being a restricted opening in said counterbalance part adjacent its intersection with said spoke part to equalize shrinkage stresses during solidification o! the metal.

14. In a driving wheel center, counterbalance structure and a spoke merging with the same and having a hollow portion communicating with a recess in said structure and adapted to receive additional weight material.

15. In a driving wheel center, a rim, counterbalance structure, a hollow spoke extending balance with its hollow interior opening through said rim, the portion of said spoke within said.

counterbalance being adapted to receive additional weight material through said rim open-- ing after said cover has been secured in place.
