TOM BENNETT and ELISE KAUFFMANN KENDALL Agents 28 Eldon Street
Finsbury London E.C. do hereby declare the nature of this invention to be as
follows:-
Fork "ends" for bicycles, tricycles & other velocipedes, by the use of which
the wheel that runs in that part, known as the "front forks," can be detached and
attached without interfering with the bearings.
They can be manufactured to fit "old forks" in use, the same as "new forks "
manufactured especially for them, they will be made in two parts, as shown by full
sized drawings attached.
"Forks" in use will be cut off at right angles 3" from the bottom end as
shown by line A' Fig. 1 & 2 and forks especially made for these ends will be
manufactured as at present, only open at each end & shorter by 3"-4" (inches).
These "fork ends" will be manufactured of steel or other hard metal & so
constructed that when brought together and bolted will form a dovetail, the weight
of the machine adjusting & locking the detachable end to the fork-forming a
complete fork-as shown by Figures Nos. 7. 8 & 9 drawings attached.
EXPLANATION OF THE DRAWINGS ATTACHED.
Fig. 1. shows the inside & Fig. 2 the outside elevation of the portion to be fitted
& brazed to the fork.
A. represents a fork, cut through at line A' or manufactured especially for
these ends.
B. B are the stubs of the portion to be fitted & brazed to the fork.
Figures 3 & 4 represent the detachable ends to be fixed by means of a bolt &
nut, the ends marked C being a quarter circle & cut on an angle of 45° & the
shoulder D being also a quarter circle & undercut at the same angle viz. 45°, the
distance between C & D Figures 1 & 2 being the same as C & D Figures 3 & 4
& the thickness of the portion between C & D being half the thickness of the
fork, as shown by Figure 9, when the two flat portions are placed together as
shown by Figures 5 & 6 and bolted together as shown by f & g the ends when
brought into their position as shown by Figures 7 & 8 form a complete fork with
a detachable end, the weight of the machine adjusts & locks h. shows where the
wheels run.

Improvements in Forks for Bicycles, Tricycles, and other
Velocipedes.
We, TOM BENNETT, Agent, and ELISE KAUFFMANN KENDALL, Married
Woman, also an Agent, both of 28 Eldon Street, Finsbury, iu the City of London,
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 object of this invention is to construct or provide the front forks of bicycles,
tricycles and other velocipedes with detachable ends so that if broken they can be
easily and rapidly replaced at small cost, and also that the wheel can be readily.
attached to or detached from the fork when desired without interference with the
wheel axle or its bearings.
In the drawings accompanying our Provisional Specification
Figs. 1 and 2 are elevations showing the lower ends of a cycle fork and the
stub pieces B¹ to be affixed thereto.
Figs. 3 and 4 represent a pair of the detachable ends B 2 to be fixed by a bolt
and nut or other readily detachable fastening to the stub pieces B¹ which are
shown in Figs. 1 and 2.
Figs. 5 and 6 are respectively inside and outside elevations showing the parts
fitted together; and Figs. 7 and 8 are similar views showing a pair of fork ends
with the parts in their proper position;
Fig. 9 is a front edge view of Fig. 7.
The saine parts are marked with the same reference letters in all the figures.
A represents the fork which is cut off straight at the line A¹, or is manufactured
specially to take the stub pieces B¹, shown in Figs. 1 and 2. B B are the
ends of the stub pieces B', one or other number of such ends B may be used
if desired, made to fit into the open lower end of the hollow fork A, into which
they are fitted, as shown in Figs. 5 to 9, and brazed or otherwise rigidly fixed in
position.
The stub piece B' is cut away on its inside for balf the thickness of the material
in the form of an arc of a circle as shown at D in Figs. 1 and 2 and its lower
end C is shaped to an arc of the same circle about the same centre. The arc
shaped shoulder D is undercut to an angle of 45°, and the end C is bevelled off in
the same direction and to the same angle, viz. 45°.
The detachable ends B 2 are shaped to fit the stub pieces B', the upper end C
being bevelled off to an angle of 45° so as to fit into the under-cut are shaped
shoulder D on the stub piece, while the arc shoulder D' is undercut to an angle
of 45° so as to receive the bevelled end C of the stub piece. The detachable
end B2 and the stub piece B' are secured together by a bolt g and nut f passed
tbrough bolt holes e in each of the parts. When fitted together the parts are of
uniform thickness as shown in Fig. 9. represents the eye for the wheel axle.
It will be obvious that with these detachable ends to the fork, the wheel can be
readily detached when desired by simply removing the nut from the bolt 9 where-
upon the wheel can be removed from the fork, and that this is accomplished
without the necessity, as is the case with forks made in one piece, of forcing the
ends of the fork apart so as to allow the axle of the wheel to be removed from the
eyes in the forks. It will also be obvious that if the fork end should break at
the eye h, as frequently happens, a new detachable end piece B2 can be readily
fitted to the fork, as these end pieces can be made in quantities and kept in stock
in various sizes, and their cost is trifling as compared with the cost of fitting a new
fork to the machine.
.

page_text: Although we have described and shown in the drawings a form of construction.
whereby the parts B' and B2 can be fitted together so as to form a fork end of
uniform thickness, we wish it to be understood that we do not limit ourselves to
this special construction, as the parts may be made of any suitable shape, and be
fitted together in any manner, provided that one of the parts can be readily
detached and that when fitted they provide a perfectly rigid connection between.
the fork and the wheel of the machine.
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 :-
1. A front fork for bicycles, tricycles and other velocipedes having a detachable-
lower end carrying the front wheel, substantially as described..
2. Fitting the front forks of bicycles, tricycles and other velocipedes with a.
detachable lower end to carry the front wheel, substantially as described.
