PROVISIONAL SPECIFICATION.
Improvements in and relating to Velocipedes.
I, CHARLES ANDREW EDWARD TALBOT PALMER of "Gairlochy" Handsworth Wood,
Birmingham, in the County of Stafford, Manager of Works, do hereby declare the
nature of this invention to be as follows:-
My improvement relates to those types of velocipedes having a single driving wheel
operated by chain gearing, and they consist of an improved construction of that part
of the frame carrying the axle of the driving wheel, and of an improved device for
adjusting the chain, the objects being the strengthening of that part of the frame
carrying the axle of the driving wheel, and facilitating the adjustment of the chain.
I attain these objects in the following manner;-I form in the ends of the prongs
of the main fork carrying the driving wheel, slots to receive the axle in the manner
already well-known. Over the open ends of the slotted ends of the prongs of the fork
I fix by suitable screws or bolts a small fork adapted to embrace the open ends of the
slotted ends of the prongs of the fork and rigidly brace them together, thus enabling
the slotted ends of the prongs of the fork to be made much lighter than usual. The small
bracing forks carry snugs to receive the prongs of the second fork in diagonal frames,
or the stays for the seat pillar tube in cross frames, and, or, to receive the stays for the
mud guard.
Through each of the openings in the ends of the slotted ends of the prongs of
the main fork formed by the small bracing forks, I pass a screw bolt having a flat
washer shaped head, so shaped and fashioned as to lie flat against the side of the
slotted end of the prong of the fork. The washer heads of the bolts are provided with
holes to receive the axle of the driving wheel. The ends of the screw bolts are pro-
vided with nuts and lock nuts so that the position of the axle in the fork may be adjusted
as desired. When the adjustment is completed the axle is locked to the fork by means
of the usual nuts threaded on the ends of the axle, and locking against the washer
heads of the adjusting bolts.

Improvements in and relating to Velocipedes.
I, CHARLES ANDREW EDWARD TALBOT PALMER; of "Gairlochy "Handsworth Wood,
Biriningham, in the County of Staffordshire, Manager of Works, 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 :--
My improvements relate to those types of velocipedes having a single driving wheel
operated by a chain gearing, and they consist of an improved construction of that part
of the frame carrying the axle of the driving wheel, and of an improved device
for adjusting the chain, the objects being, the strengthening of that part of the
frame carrying the axle of the driving wheel, and facilitating the adjustment of the
chain.
I attain these objects in the manner shown in the accompanying drawing in
which

page_text: Throughout the several views similar parts are marked with like letters of
reference.
I form in the ends of the prongs of the main fork A adapted to carry the
driving wheel of which the hub B only is shown, slots a to receive the axle b. in
the manner already well-known. Over the open ends of the slots a in the ends of the
prongs of the fork A are small forks C adapted to embrace the open ends of the slot a
in the ends of the prongs of the fork A and rigidly brace them together, thus enabling
the slotted ends of the prongs of the fork to be made much lighter than usual. The
small bracing forks C are fixed to the slotted ends of the prongs of the fork A by
means of small bolts or screws c. c and they carry snugs c¹ to receive the ends of
tubes D forming either the second fork in diamond-shaped frames, or the stays for
the seat pillar tube in cross frames, and also snugs for the stays for the mud
guard.
Through each of the openings in the ends of the slotted ends of the prongs of
the main fork A formed by the small bracing forks C, I pass a screw bolt E having
a flat washer-shaped head e so shaped and fashioned as to lie flat against the side of
the slotted end of the prong of the fork A. The washer heads e of the bolts E are
provided with holes to receive the axle . of the driving wheel. The ends of the screw
holts E are provided with nuts E', and also locknuts if desired, so that the position of the
axle b. in the fork A may be adjusted as desired. To adjust the driving chain the nuts 61
on the ends of the axle b. are slackened. The axle b. is then drawn backwards by means
of the nuts E on the bolts E until the desired adjustment is obtained, then the axle b.
is locked to the fork A by means of the nuts 61 thereby at the same time locking the
washer heads e of the adjusting bolts E.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
Li
1st. The improvements in velocipedes as herein described and shown in the accom-
panying drawing.
2nd. In a velocipede having a single driving wheel the axle of which is carried in
the slotted ends of the prongs of a fork, bracing the open ends of the said slotted ends of
the prongs of the fork by means of small bracing forks adapted to carry snugs for the
supplemental fork or its equivalent of the frame and for the mud-guard stays, and
providing for the adjust ment of the driving chain by means of bolts embracing the
axle of the driving wheel passing through the small bracing forks on the slotted end
of the prongs of the main fork, and adapted to be adjusted therewith by means of
nuts threaded on to the said bolts and bearing against the small bracing forks, as
set forth.
3rd. In a velocipede the axle of the driving wheel of which is carried in the
slotted ends of the prongs of a horizontal or approximately horizontal fork, bracing
the open ends of the said slots by means of small forks carried by the other members
of the frame, and adapted to receive the bolts for the adjustment of the axle in the
slotted ends of the prong of the main fork, as set forth.
4th. In a velocipede the combination with the slotted ends of the prongs of the
fork A, of the forks C embracing the open ends of the slotted ends of the prongs of
the said fork and fixed thereto by the bolts c. c, the snugs c¹ on the forks C adapted
to carry the other members of the frame, the bolts E with washer heads e. adapted to
embrace the axle b, and the nuts E¹, all combined, arranged, and operating, as and
for the purpose set forth.
