* LOCKE `8L J. CLARK. improvement, in Hubs for Carriage-Wheels.-
Patented Oct. 1., T872.'
Witnesses JOHN LOOKE, OF LEWISB URG, AND JOHN CLARK, OF MILROY, PENNSYLVANIA.
IMPROVEMENT IN HUBS FOR CARRIAGE-WHEELS.
Speciication forming part of Letters Patent No. 131,887, dai-ed October 1,1872.
To all whom it may concern:
Be it known that we, JOHN LOOKE, of Lewisburg, in the county of Union and State of Pennsylvania, and JOHN CLARK, of Milroy, in the county of Mifflin and State of Pennsylvania, have invented a new and valuable Improvement in Wheel-Hubs 5 and we do hereby declare that the following is a full, clear, and exact description of the construction and Operation Of the saine, reference being had to the annexed drawingmaking a part of thisspeciteation, and to the letters and figures of reference marked thereon.
Figur-el of the drawing is a representation l l of a front view, showing the modifications of my invention; Fig. 2 is a longitudinal central sectional view of the same. Fig. 3 is the same.
This invention has relation to metallic hubs for wheels 5 and it consists in the construction and novel arrangement of the sections composing the hub; in the form Of the fasteninglugs, and their relation to the ends and shoulders of the spokes.
The accompanying drawing illustrates this invention as follows: The letter A designates the box, onwhich is cast the disk or flanch B. O represents the exterior disk or outer section of the hub, provided with a sleeve, a., and the dovetail lugs b, arranged ina circular series On the inside Wall of the disk next the periphery thereof. These lugs are dovetail in form, as shown in Figure l-the larger ends being towardA the center. E represents the nut, which is screwed on the box and serves to keepthe disks securely together. F designates the spindle of the axle, G the cap, and H the spokes; Each spoke is formed with a Wedge-shaped end, c-the bevel'of the sides of this end being regulated by the number of spokes in the wheel; these ends c being designed to :fit closely together around the sleeve a. Each spoke is notched on both sides f to receive the two dovetail lugs which are ad- 0 jacent thereto.
The notch e has two sides, meeting at an angle. One of these sides, fm,
is at right angles, or thereabout, with the direction of the spoke, forming a secure shoulder,
which will prevent the spoke from drawing out. The other side, n, is beveled obliquely outward and forward tO t closely the inclined side Of the lug `which forms its bearing. Itis apparent that the expanded shoulder z of the spoke renders it strong at the junction with the hub.` This formation is rendered possible by the form of the lug. Between the lugs and the sleeve a the space is filled with the closelyiitting ends of the spokes, forming a compact ring of Wood. Sometimes the lugs, instead of being attached to the outer disk, may be cast on the box-disk; but the arrangement tirst described is preferred, because the box ca'n be easily replaced when worn out without disturbing the spokes in theirbearings. The lubricatingrecesses fu o are indicated in `Fig.-3 of the drawing. These recesses or shallow cells are arranged in the'length Of the Wall of the box in such a way that the cells alternate with the wall s Of the box in a checkered manner, as illustrated, so that the bearing of the box on its spindle shall be uniform throughout its length.- Between each cylindrical arrangement of recesses the wall of the box is entire for a short distance, as at s', forming rings or bearings at diti'erent points, fitting the spindle closely. A great quantity Of lubricating mat- .ter can be contained in these cells, and the friction of the box. will be decreased by the -lessening Of the bearing-surface, the arrangement being such as to preserve the bearing uniform.
What I claim as my invention, and desire to secure by Letters Patent, is-
The combination, with the notched spokes, of the wheel-hub, made in two sections Or disks, one of which is provided with the series of peripheral dovetail lugs, having their large ends lying inward, substantially as specified.
' In testimony 'that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
