CHARLES F. GRAVER AND JAMES M. WISHART, OF GRINNELL, IOWA.
IMPROVEMENT IN DRIVING-WH EELS.
Specification forming part of Letters Patent No. 212,663, dated February 25, 1879; application filed December 21, 1878.
To all whom 'it may concern:
Be it known that we, CHAELEs F. GRAvER and JAMES M. WIsHART, of Grinnell, in the county of Powesheik and State of Iowa, have invented a new and valuable Improvement in Drive-Vheels; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specilication, and to the letters and figures of reference marked thereon.
Figure l of the drawings is a representation of a side elevation of our drive-wheel, and Fig. 2 is a perspective view of the metal axle.
Our improvement relates to driving-wheels for locomotives and the like, or a drivingwheel for machinery 5 and the novelty consists in the construction and arrangement of parts, as will be` more fully hereinafter set forth.
In carrying out our invention we construct our improved drivin g-wheel with the hub and rim of cast-iron, and cast into these parts the spokes, which are of hollow wrought-1netal pipes.
Cast with the hub are radial arms, the outer ends of which are perforated or otherwise formed to receive securing-bolts, which connect the master-wheel thereto.
Heretofore difficulty has been experienced in casting wrought-iron spokes into cast hubs and rims, the parts not forming solid welding-joints because of the solid cold Wroughtiron chillin gthe molten castiron at these points. We overcome this difficulty by employing spokes of hollow wrought-metal pipe, which fuses readily with the east metal and forms a rigid joint. Said spokes are light, elastic, and have sufficient strength for the purpose.
Heretofore the strain of the runnin g machinery or power has been directly on the spokes of the wheel, the master-wheel being secured thereto or formed in one therewith. This we deem deleterious in its results; and to avoid it we cast in one piece with the hubs radial arms, to which the master-wheel is secured in any desirable manner.
Referring to the drawings, A represents the hub, of cast metal, having cast in one therev with the radial arms A', with securing device a', to receive the master-wheel. (Not shown.) B designates the rim of the driving-wl'leel, of cast metal, and C the curved wrought-iron spokes, of hollow pipe metal, as shown. These spokes are cast with the hub A Al c and the rim B, and form a rigid wheel.
D represents the metal axle, having spindle d, upon which the wheel is secured, and upon which it revolves. A box, Dl, is cast in one therewith, having closed sides d and open top and bottom. Upon the outer end, next the spindle, is a cross-plate, D2, and upon the upper inner end is a cross-plate, D.
The parts are all cast in one, and the sides d d and plates D2 D3 form a socket-bearing for a wooden axle. (Not shown.)
What we claim as new, and desire to secure by Letters Patent, is-` The hub A, having radial arms A c', in. combination with the spokes C and rim B, as specified, for connecting the drivedvlleel with a master-wheel, as set forth.
In testimony that we claim the above weA have hereunto subscribed our names in the presence of two witnesses.
