AGE, ULes Lane corner of
town Philadelphia, Pennsylvania, both in the United States of America, do hereby
declare the nature of this invention, and in what manner the same is to be
performed, to be particularly described and ascertained, in and by the following
statement:
The invention consists of a centre or body for a vehicle, bicycle, polishing,
grinding or other wheel, or a hub, pulley or the like, which is formed of separate
peripheral and central portions, the same being connected by springs, thus imparting
elasticity to the centre, and also adapting the periphery to yield when subjected to
pressure or strain.
In the accompanying drawing,
يا
Figure 1 represents a side elevation, partly broken away, of a centre or the like
embodying this invention.
Figure 2 represents a cross section thereof.
Figure 3 represents a side elevation of one of the springs thereof.
Similar letters of reference indicate corresponding parts in the several figures.
A designates a hub, from which radiate the flanges B, which are freely encircled
by the annuli C, the outer peripheries of which have flanges D thereon, the same
projecting inwardly or towards each other, forming the rim E.
F designates threaded bands which are fitted to the threaded portions of the
rim E, and may be moved towards or from each other by proper rotation of
the same.
"
G designates bolts which are connected with the flanges B, and H designates
bolts which are connected with the annuli C, it being noticed that sail bolts extend
parallel with the hub A.
In the space formed by the rim E and hub A, are bent springs J, which are
formed of the coils or eyes fitted alternately or in somewhat zig-zag order on the
bolts G, H, it being seen that the annuli C are connected with the flanges B of the
hub, and consequently with the hub by said springs J, which connection is
exceedingly firm in its nature, so that the parts may revolve as one, but the
same is elastic or yielding.
The hub and rim with the intermediate parts may form the centre of a wheel of
a vehicle, or the like, the hub being placed on an axle or bearing, so as to either
revolve upon or with the same. Again, the rim E may form the periphery of said
wheel, or the hub of the wheel may encircle the rim E, and be firmly secured
thereto, the spokes of the wheel being secured to said huh. The bands F may be
moved closely against the sides of said hub, and be screwed bolted or otherwise
secured thereto, but in either case there is provided an elastic structure which
renders the riding or use of a wheel if that of a vehicle of an easy, gentle and
comfortable nature.
Should there be any extraordinary pressure or strain upon the periphery of the
wheel, whereby motion of the latter is resisted, said periphery may yield or hold
back sufficiently to prevent injury to the parts. When the wheel is relieved of
such pressure or strain, its periphery moves forward and so resumes its original
position.
The flanges and annuli brace and sustain each other in lateral directions, and the
bolts G and H serve to strengthen the structure, thus providing a strong, durable
and serviceable device.

page_text: The centre may also be employed to support a grinding or polishing wheel
surface or stone, the same being fitted on the rim E, and secured thereto so as to
revolve with the hub as one.. Should however, any extraordinary pressure or strain
be applied to or exerted upon the wheel or stone, whereby the latter is resisted, it
yields or holds back sufficiently to prevent injury to or breakage of the wheel or
stone, or its carrying parts, the effect of which is evident.
When the wheel or stone is relieved of the pressure or strain, it moves forward
and resumes its original or normal position.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1st. A centre or body consisting of hub and peripheral portions and springs
which extend from one portion to the other, the peripheral portion being loosely
mounted on the hub portion and connected by said springs which are attached
respectively to the bolts of said portions, substantially as described.
2nd. A centre or body consisting of a hub having flanges thereon, annuli freely
encircling said flanges, and provided with a rim, and a spring or springs between
said hub and rim, said parts being combined substantially as described.
3rd. A centre or body consisting of a hub with radiating flanges, annuli
encircling said flanges having inwardly projecting flanges thereon, forming a rim,
bands fitting on said rim, bolts connecting said hub flanges, bolts connecting said
annuli, and springs connected with said bolts, said parts being combined substantially
as described.
4th. A centre or body formed of annuli with a peripheral rim and a hub portion
separate therefrom having a flange radiating therefrom, and springs having eyes at
their ends and intermediate of their ends and extending from the bolts of the rim to
the bolts of the hub and connecting said peripheral rim and hub portion, substantially
as described.
5th. A centre or body consisting of a hub having flanges thereon, annuli
encircling said flanges and having inwardly projecting flanges forming a rim,
bands on said rim, and a coiled spring having eyes on securing bolts for said hub,
flanges, and annuli, said parts being combined substantially as described.
6th. A centre or body consisting of a hub with flanges, annuli encircling said
flanges, and having a rim, bands on said rim, bolts connecting said flanges, bolts
connecting said annuli, and springs having eyes at their ends on the bolts of said
flanges, and intermediate eyes on the bolts of said annuli, said parts being combined
substantially as described.
7th. A hub with radial flanges having connecting bolts, annuli encircling said
flanges and having connecting bolts, bands on a rim formed by the flanges of said
annuli, and springs having coils or eyes fitted alternately on the bolts of said flange
and annuli, forming a yielding periphery, said parts being combined substantially as
described.
8th. A body or frame formed of separate parts which are connected by springs,
the operation of the same being substantially as described.
