PROVISIONAL SPECIFICATION.
Improvements in the Construction of Wheels.
1, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a communi-
cation to me from abroad by George C. Richards, and R. A. Shade, of Sisson,
California, U.S.A. Gentlemen,) to be as follows:-
This invention has reference to certain new and useful improvements in wheels,
and the invention relates to certain means whereby the spokes are secured in the
felly, whereby the said felly may be conveniently tightened as desired.
By this invention the felly has a socket, and a spoke has a tenon fitting said
socket. A protecting plate is fitted around the spoke socket and extends up along
each side of the felly to prevent the splitting of the same. A sleeve is arranged
upon the spoke tenon, and has a head which is provided with a concave seat,
adapted to receive a convexed portion at the base of the tenon. A nut is arranged
upon a threaded portion of the sleeve, and has a flange on its under surface, and a
split washer between the nut and head of the sleeve, said washer being held in
position by the flange, and a curved surface on the upper and outer surface of the
head.

COMPLETE SPECIFICATION.
Improvements in the Construction of Wheels.
1, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a communi-
cation to me from abroad by George C. Richards, and R. A. Shade, both of
Sisson, California, U.S.A. Gentlemen,) and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
My invention relates to that class of adjustable spoke-sockets in which the spoke
is adjustably connected with the felly, said adjustment being controlled and operated
by a nut, the effect of which is to vary the length of the spoke, thereby tightening
the tire, the felly, and the spoke.
My invention consists of the novel combination and arrangement of parts, herein-
after fully described, and specifically pointed out in the claim.
The object of my invention is to provide a simple, effective, and practical device
of this class.
Referring to the accompanying drawings for a more complete explanation of my
invention,
.
Figure 1 is an elevation of my device, Fig. 2 is a section thereof, and Fig. 3 is a
detail view.
A is the felly, and B is the tire of a wheel. In the felly is made the socket a,
and around the entrance to this socket is the protecting-plate a', fitted and secured
suitably to the felly. C is the spoke having the tenon c.
D is a metallic sleeve
provided with a head d,-and having external screw-threads extending from the
head throughout a portion of the length of said sleeve. E is the adjusting nut
seated on the threaded sleeve, which sleeve is threaded double the thickness of

page_text: the nut to permit the opening and tightening of the joint of any two sections of the
felly.
Fis a split washer, adapted to be fitted upon sleeve D between its head d and
the adjusting-nut. E and to be confined therein between a flange F¹ on the lower
outer surface of the nut and a slightly-convex surface on top of the base of the
metallic sleeve. These several parts are fitted together as follows: The outer end
of the sleeve D is inserted freely in the socket a of the felly. The spoke tenon c is
inserted in and passed through the sleeve, fitting its convex base or shoulder tightly
against the concave head of the sleeve to prevent spreading and crushing the
shoulders, and in all cases of the shrinkage of the spoke the sleeve may be perfectly
tightened by a light pressure exerted by tightening the nut E. The adjusting-nut
is run back on the sleeve so as to rest against the head, and thus the sleeve_
penetrates the socket, in the first instance, to its farthest limit, so that the nut lies
between the head d and the protecting-plate a'. Now when adjustments are needed
to tighten the parts the nut is turned so as to move farther out away from the
head d, and as it bears against the plate a' all the time and works on the threaded
sleeve it forces the sleeve back out of socket á, or what is the same thing presses
the felly outwardly on the sleeve, having the effect of lengthening the spoke, and
thereby producing the necessary tightening. Then in the space between the head d
and the nut the washer F is fitted to fill up and to hold the nut. In this construc-
tion the parts are all out of the way and do not present the bad appearance of those
devices which embrace the felly and only partly receive the spoke tenon, which in
my case is made long and enters the felly through the sleeve, which is itself seated
in-the-felly.
In order to make the joint between the spoke or tenon shoulder and the head d
of the sleeve as perfect and complete as possible, I concave the head and convex the
-shoulder, as shown.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:
In combination with a felly having a socket and a spoke having a tenon fitting
said-socket,-a-protecting-plate-fitting-around-the-spoke-socket-and-extending-up
along each side of the felly to prevent the splitting of the same, a sleeve upon the
spoke tenon, having a head provided with a concave seat adapted to receive a
