VEHICLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 425,898, dated April 15, 1890. Application filed January 18, 1890- Serial No. 337,318. (No model.)

To all whom, it may concern;

Be it known that we, JOHN ALEXANDER MORSMAN and EDWARD H. I-IIGBY, citizens of the United States, residing at Mapleton, in the county of Bourbon and State of Kansas, have invented certain new and useful Improvements in Vehicle-Vheels; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

VThe present invention has relation to that class of vehicle-wheels for which a patent was granted to us November 19, 1SS9,N0.415,117, and is designed as an improvement thereon, the object of the invention being to improve the construction of the wheel, whereby a Wood center or core may be employed, which is driven into the center of the hub and afterward bored out the required diameter to receive the ordinary thimble-skein or box, which is wedged into it as in the ordinary wooden hub, thus with comparatively little trouble adapting the hub to skeins or boxes of varying sizes or diameters and the consequent decrease in the cost of manufacture.

A further object of the invention is to improve the wheel in the several details of construction, whereby a cheaper, stronger, and more durable wheel is provided that is equally adapted for use upon spindles and all other places where a Wheel is required and found useful, these several objects above enumerated being attained by the construction substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying diawings,\vliich form a part of this speciiication, Figure l is a longitudinal vertical section of the wheel, showing the wood center or core, thimble-skein or box, and the axle in position; Fig. 2, an outer face view of the wheel, showing one of the iianged plates partly broken away; Fig. 3, an inner side view of one of the plates; Fig. 4, a detail view in perspective of one of the wedgeblocks Fig, 5, a sectional view taken on line of Fig. l.

In describing the construction of our invention by reference to the drawings, the hub, as in the former patent, hereinbefore referred to,

consists, principally, of a main casting, which comprises a central longitudinal sleeve of any desired length and diameter, as shown at A. This sleeve at or near its center is cast with an annular or circumferential body B, which is .of slightly-tapering form, commencing at a point from the laterally-extending annular ange a and decreasing in thickness as it approaches the outer edge or periphery of the body. This tapering form of the body B is deemed preferable lfor some purposes and for some classes of wheels; but the taper of the body maybe dispensed with when found necessary or desirable.

The annular flanges a are cast with the body B about one-third the distance of the length thereof when viewed in cross-section, as shown in Fig. l, thereby leaving a space b between the flange and the sleeve to allow access to the nut c upon the screw-threaded end of the spokes C of the wheel, also to admit the wedge-blocks to enter. The spokes C, which pass through holes in the anges a, rest in grooved seats d, which extend radially upon the sides of the body B from the periphery thereof to the iianges.

The clamping-plates D E are preferably of circular form and are substantially alike, the necks or iianges of the plates being of sufficient length to protect the parts which they inclose, and to prevent mud, dust, and the like from falling on the nut or other vparts inclosed by the necks or iianges, which would find its way into the box or thimble and thereby create undue friction. The clampingplates are each formed with an opening e to receive its respective wedge -block F, said opening extending also through the necks or 'lianges f,'for the ready insertion of said wedgeblock, which is held therein by a headed rod g, passing through the same, said rod also passing through the body B and the opposite one of the clamping-plates, a nut h engaging with the screw-threaded end of the rod. The interior sides of the clamping-plates D E have rabbeted faces 71,', these faces overlapping the iianges a, rods i', which pass through both the body B and the plates, holding the latter firmly in place, as do also the rods g, the former mentioned rods having screwthreaded ends to receive nuts 7c.

The clamping-plates D E have upon their inner face radial grooves Z, which correspond in form to the grooves d and together form seats for the spokes, the shape of the grooves corresponding with that of the ends of the spokes.

When the spokes C are in position and seated in the grooves d of the body B, and the plates D E are drawn tightly againstthe spokes, With the grooves Z fitting over the .outer half thereof, the drawing of these plates toward each other and against the spokes by means of the rods t' and the screw-nuts lc, by which they are entirely surrounded, prevents any vibration of the spokes at points where they are weakened by screw-threading or riveting, thereby rendering the spokes much `stronger and more durable and less liable to break at their screw-threaded or riveted ends.

The rods g, which pass through the Wedge blocks F, serve to draw the blocks inwardly, and thereby wedge themselves between the outer periphery of the sleeve A and the clamping-plates, which bind them firmly together and form a perfect and rigid connection between the two. The sleeve A is cast upon its inner side with one or more feathers m, which are preferably V-shaped, as shown in Fig. 5, and may extend the entire length of the sleeve, or only a portion of its length, as found desirable, and, if preferred, the feathers may be of any shape found most practical for the purpose, which is to prevent a wooden core,

as shown at G, from turning around in the sleeve. The feathers are preferably made V- shaped for the reason that the feather or feathers will out their own way into the wood as the core is being driven into the sleeve.

This wooden core we consider one of the essential features of our invention, as the sleeve by the wooden core can be adapted to thimbleskeins or boxes of different diameters. In applying the wooden core to the sleeve a solid piece of Wood is first taken and driven into the sleeve and is held from turning therein by the feathers hereinbefore described, after which the core is bored out the proper size to receive the 'ordinary thimble-skein or box, as shown at H, into which may be inserted the axle I or spindle, as the case may be.

'The advantage of the employment of the wooden core is that it removes the great expense in the manufacture, as heretofore it was usually necessary to bore out the metal hubs to adapt them to fit thimble-skeins or boxes of varying sizes and diameters, while with the wooden core the skein or box, which comes already fitted with the spindle, can be wedged in the wooden core as in wooden hubs. The practical advantage of such Wooden core will be at once apparent fromthe fact that it is a very easy task to bore out the wooden core to fit any skein or box. It is evident that either bolts or rivets may be used for connecting the parts together, and many modifications may be made in our invention in the several details of construction without departing from the principle thereof, as we reserve the right to make such changes or modifications as would come within the scope of ordinary mechanical skill.

A Wheel constructed in accordance with our invention possesses both a very markeddegree of strength, durability, and wear, and wearing loose of the spokes by any strain or hard usage of the wheel, and consequent rattle of the spokes, is entirely avoided.

Having now fully describediour invention, what we claim as new, and desire to secu re by Letters Patent, is- Y l. In a vehicle or other wheel, a `central sleeve cast upon its interior with feathers and having a circumferential body to which the spokes are attached, and independent clamping-plates connected to said body, in combinationwith a woodenA core fitting into the sleeve, and a thimble-skein or box Within the core, substantially as and for the purpose set forth.

2. In a vehicle or other wheel, the spokes and clamping plates, in combination with wedge-blocks enteringopenings in the plates, andscrew rods andnuts for drawingthe wedgeblocks toward the center of the'hub,substan tially as and for the purpose specified.

3. In a vehicle or other Wheel, the combination, with a central body having upon its sides radial grooves to form seats for the spokes, of two clamping-plates having corresponding grooves to fit over the spokes and hold them in position, substantially as and for the purpose set forth,

In testimony that we claim the v4above we have hereunto subscribed Your names in the presence of two witnesses.
