HUB.

Specification of Letters Patent.

Patented Aug. 11, 1908.

Application filed March 13, 1908. Serial No. 420,885.

T all whom it may concern:

Be it known that I, CLARENCE HEATH, a citizen of the United States, residing at Shortsville, in the county of Ontario and State of New York, have invented certain new and useful Im rovements in Hubs and I do declare the fo lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the of reference marked thereon, which form a part of this specification.

This invention relates to vehicle wheel hubs; and the main object is to provide an improved form of combined metal and. wood hub whereby the assemblage of the various parts may be facilitated, convenience in manufacture may be attained, the construction being such. that a secure locking between the separate parts may be effected and the conventional form and appearance of the hub retained.

To the accomplishment of the foregoing form of hub; Fig. 2 is a longitudinal verti cal section thereof Fig. 3 is a longitudinal vertical section of the middle bond and a modified form of front band, unassembled; Fig. 4 is a longitudinal vertical section of a modified construction of hub; and Fig. 5 is a modified form of the outer band.

In the drawings, the numeral 1 indicates the body portion of the hub, provided with a longitudinal bore in which is inserted the bushing 2. The body of the hub is turned down throughout a portion of its length forming the reduced portion 3 which. referably has a tapered portion 4 and is pre erably reduced still further in diameter to form the outer end portion 5. preferably terminates in a shoulder or abutment 6 which is provided with an overhanging annular flange .or shoulder 7 forming a recess 8 between said shoulder and reduced portion 3. The upper or outer surface of the shoulder 7 has a portion beveled upwardly as 9 and from that point the hub body has a The reduced portion 3 portion 10 which is reduced to conform to the conventional design and terminates at its inner end in a cylindrical ortion 11. To this portion 11 is fitted the utt or inner reinforcing band 11% In the portion 3 of the hub are provided the requisite number of .radial sockets or mortises 12 to register with the corresponding openings or slots 13, formed in the middle band 14. The slots are preferably arranged in a staggered series. This band 14 is of suitable strong and malleable metal and has such an internal diameter as to enable it tofit closely over the reduced portion 3. This metallic band has circular recesses 15 and 16 formed in its opposite sides, the body portion extending beyond the recesses to form flanges or ribs 17 and 18 above the recesses and flanges 19 and 20 below the recesses, the lower flan es preferably extending beyond the upper anges. The upper flanges 17 and 18 are formed with their inner Walls 21 and 22 tapering downwardly to the bottom walls 23 and 24 of the recesses.

The outer band 25 is formed with a cylindrical outer end .portion 26 having such an inner diameter as to fit snugly over the outer portion 5 of the hub. The cylindrical wall of the band diverges slightly from its outer end toward the inner end and about midway of its length the divergence is considerably i11- creased forming the inclined portion 27. When the external diameter of the outer band approximates the external diameter of the middle band, then it is formed with a horizontally extending portion 28. This is adjacent to the inner end portion 29, which is first inclined inwardly forming the beveled ortion or shoulder 29 corresponding to the inclined wall 21 and then bent further inwardly until the vertically extending shoulder-or flange 30 is formed which is adapted to fit into the recess 15. The inner end 31 fits snugly over the upper surface of the lower flange 19 of the recess 15. The width of the end 31 of the shoulder or flange 30 is less than that of the flange 19. The inner or end portions 30 and 31 of the outer band 25 are preferably retained with solid surfaces, but they may be formed with slots or notches 32, as shown in Fig. 5, for convenience and facility in fitting the portions of the hub together.

The parts of the hub are put together and looked as follows. The two bands 14 and 25 are secured together by forcing the inner end 29 of the outer band 25 into the recess 15 of the middle band, the shoulder or flange 30 fitting against the bottom wall 23 of the recess, the inclined portion 29 abutting against the inclined Wall 21 and the end 31 of the flange or shoulder 30 snugly encircling the flange 19. As the end 31 of the flange 30 is of less width than the flange 19 a short end portion 33 is left which is bent or spun over the end 31 of the flange or shoulder 30, thus securely locking the two bands together. The two bands are now forced onto the wooden hub, the cylindrical portion 26 fitting the portion 5, the sockets 12 and 13 reg istering, the flange 20 extending into the recess 8, the flange 7 into the recess 16, and the beveled portions 9 and 22 abutting against each other. The hub is securely locked together, the locking device being completely inclosed and the exterior surface of the hub is continuous and of conventional design.

I have described the preferred form of hub, but the construction may be modified as shown in Figs. 3 to 5. As already described a part of the wood portion of the hub is exposed and is only reinforced by a narrow band. In the modified form this portion of the hub is made to correspond to the outer part of the preferred form, and thus the wood used in the hub is completely covered and reinforced by the metallic shell or casing.

The middle and outer bands are the same as in the preferred form but the construction of the inner portion is similar to that of the outer portion. The hub is reduced throughout its length as shown. 'The inner or butt band 34 is of substantially the same form as the outer band 25 in so far as the locking means is concerned, having its end portion 35 formed with an inclined portion 36, a vertical portion or flange 37 and having the lower or inner end of this flange fitting snugly over the outer surface of flange 20. The parts are secured together as described in detail hereinbefore in reference to the preferred form. It is obvious that the inner band only may be used and locked to the middle band by this upturned flange.

The hub constructed according to this in vention is simple, strong and efficient, and the few parts are readily put together with the greatest economy of material and time.

The parts are locked together internally, simply and securely, and thus the appearance of the hub is not marred by unnecessary beads, flanges, etc. It possesses maximum durability in that the Wood is reinforced by the metal and the locking means is not exposed thus reducing if not eliminating entirely the risk of the parts becoming detached from each other.

Having described my invention and set forth its merits, what I claim is 1. In a wheel hub, the combination with a core, of a band formed with a recess and a horizontally extending flange formed within the external surface of said band, and a second band or sleeve secured to said first band by means of said horizontal flange, substantially as described.

2. In a hub, the combination with a core, of a band provided with a horizontal flange formed within the exterior surface of said band, and a second band secured to said first locked to the flanges within the exterior sur-' face of the hub, substantially as described.

5. In a hub, the combination with a band provided with horizontal flanges one each side, of bands having end portions fitting between said flanges and provided with vertical portions the ends of which fit over the lower flanges, a portion of the lower flanges being bent over the end of said vertical portions.

In testimony whereof I aflix my signature in presence of two witnesses.

CLARENCE HEATH.
