Application led May 25, 1915. Serial No. 30,415. g
To all whom it may concern:
Be it known that I, FRED O. FERMIN, a citizen of the United States, residing at Portland, Multnomah county, State of Oregon, have inventedv certain new and useful Improvements in Wheel-Hubs, of which the following is a specification.
y invention relates to wheelhubs, and especially to the hubs of amusement wheels, as merry-gorounds and the like, and has for its objects the provision of a wheel hub that may easily and quickly be assembled, that is strong and safe in operation, and that is cheap to manufacture.
I accomplish the'above objects by means of the construction described in these specifications and illustrated in the accompanying drawing which therefore becomes a part of this application for Letters Patent, and in which Figure l is a longitudinal section of a wheel hub, embodying my invention, as assembled upon a shaft. Fig. 2 is an enlarged view, showing in detail the construction of my invention. Fig. 3 is a plan View of Fig.
l, partially broken away to illustrate the construction. Fig. 4 is a perspective view of one of the arm segments.
Like characters designate like parts throughout the several views of the drawing, in which Numeral l represents the members of the wheel arms, which may be constructed in any convenient manner, the drawing showing steel angles. The wheel is to be constructed of a plurality of' arms, and secured to each arm is a segment having a radially extending flange 2, and a hub portion 3. Said hub portion is provided with a conical surface 4 adapted to receive a retaining ring 5. That portion of hub 3 opposite surface 4 may be constructed to fit into a flanged pedestal or other structure as shown at 6 in Figs. 1, 2 and 4, or it may be constructed with a conical surface 7, similar to surface 4, adapted to receive retaining Fig. 1. Bolts 9 passing between flange portions 3 of the segments are adapted to clamp said segments between the retaining ring and the pedestal, or the ange 10 as shown in Fig. 2. Bolts 11 passing between ange portions 3 of the segments are adapted to clamp said segments between the retaining ring 5 and retaining ring 8. Said clamping action draws the retaining rings upon the conical surfaces 4 :and 7 respectively, and this draws thel segments tightly up to the central shaft 12.
In practice my invention may be used in several different combinations as follows: Fig. 1 shows the construction as adapted to a large amusement wheel turning in a substantially horizontal plane about a pillar or pedestal, in which two hubs are used, the lower hub fitting the flanged pedestal, and the upper hub having two retaining rings. A single hub may be used, resting upon a flange upon the shaft-as shown in Fig. 2. A single hub having two retaining rings similar to that shown in the upper portion of Fig. 1 may be used.
My invention may be constructed of any material, and made of any size deemed suitable and convenient for a device of this character, and is not to be construed as limited to amusement wheels, but is to be considered as applicable to all wheels wherein such a device may be applicable, and while I have illustrated and described a preferred form of construction deemed advisable in materializing my invention, I wish to include in this application for Letters Patent all mechanical equivalents or substitutes Y that may fairly be considered to come within the scope and purview of my invention as defined in the appended claims.
Having now described my invention so that others skilled in the art may be enabled to construct and use the same, what I claim as new and desire to secure by Letters Patent, is
1. A wheel having a plurality of arms, in combination with a hub comprising a plurality of segments, each segment having a flange portion adapted to be connected to one of saidarms, and a hub portion with a conical surface thereon, and retaining rings adapted to clamp upon said segments, said retaining rings having conical surfaces adapted to engage the conical surfaces upon said segments in such a manner as to produce a force upon each segment normal to the central axis of the hub.
2. In an amusement wheel, a revolving pillar or column, a flange upon said pillar, a shaft mounted in said pillar, a wheel having a plurality of arms and two hubs, the lower hub consisting of a plurality of segments adapted to engage said flange, each segment having a conical surface thereon, and a retaining ring adapted to engage said conical surfaces upon said segments; the
upper hub consisting of a pluralityv of seg- Y ments, each segment having oppostely ds-. posed conical surfaces, aduahty of'retaining rings adapted to engage said conicalV 5 surfaces upon the segments of said upper hub, and means to clamp said retaining rings upon the said segments Copies of this patent may be obtained fo r -ie cem-5 each, by 'MIWESinQ"the Commissioner of Patents, WashingtonJLCP v
