Improved Means for Adjusting Cycle Chains, with Facility of
Removing and Replacing and Regulating Position of Hind Wheel.
I, ALFRED HENRY CULLEY, of 139 Brayard Road, Peckham, County of London,
Cycle Tyre Fitter, do hereby declare the nature of this invention to be as
follows:-
This invention has for object, certain means for adjusting Cycle Chains without
altering the bearings of the hind wheel, also in means for adjusting the bearings
without altering the chain.
The hind wheel can be removed and replaced without altering the chain adjust-
ment, the wheel can always be set centrally in the back fork legs of the frame
and with a firm connection between the frame and the hind wheel spindle.
For the purpose of my invention, I form lips or extension pieces on the bearings
of the back stays to engage in and be clipped to the rear ends of the back fork
legs, or I form the clipping devices on the lower ends of the back stays for the
reception of lips or extensions of the back fork legs. I also slot the under side
of the back stay bearings and secure the hind axle by pinch nuts thereto.

Improved Means for Adjusting Cycle Chains, with Facility of
Removing and Replacing and Regulating Position of Hind Wheel.
I, ALFRED HENRY CULLEY, of 139 Brayard Road, Peckham, County of London,
Cycle Tyre Fitter, 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:―
This invention has for object, certain means for adjusting Cycle Chains without
altering the bearings of the hind wheel, also in means for adjusting the bearings
without altering the chain.
The hind wheel can be removed and replaced without altering the chain adjust-
ment, the wheel can always be set centrally in the back fork legs of the frame
and with a firm connection between the frame and the hind wheel spindle.
For the purpose of my invention and as shown in the annexed drawings, I
form lips or extension pieces on the bearings on the back wheel to engage in and

page_text: be clipped to the rear ends of the back fork legs, or I form the clipping devices on
the lower ends of the back stays for the reception of lips or extensions of the back
fork legs. I also slot the under side of the back stay bearings and secure the hind
axle by pinch nuts thereto. I also use an adjusting screw for setting and fixing
the parts at their respective distances.
The invention is fully shown in the annexed drawings.
Figure 1 back end elevation of one of the back stays of a cycle.
Figure 2 side elevation of the back stay and portion of one back fork partly in
section and having the rear axle nut in place.
Figure 3 side elevation of the parts with my clipping device in situ but close
home for an unstretched chain.
Figure 4 side elevation of a portion of a rear stay and rear fork with my clipping
device supplemented by a set screw which locates the parts should the clip
become loose from any cause, or for adjustment before clipping up.
Figure 5 detail of appliance by which from a round head or axle socket a
washer can be utilised for a flat nut to be affixed, the curve of the washer by its
contact with the head being sufficient to prevent the axle dropping out, except
when the nut is completely removed.
A, back fork with hand clip or clamp F and lug B. G, plug or extension. for
insertion into A. I, back wheel axle binding nut. J, concave faced washer
seating on E and G, giving a flat seating for I. H, slot to allow of speedy removal
of the back wheel. C, adjustment screw with head fixing into lug B and recessed
into back stay E. D, locking nut on screw C.
In practice, it will be gathered that by easing the clamp F and turning the
nut D the extension G carries with it I, this causes J and G to be pushed away
whereby the chain beomes tightened.
The advantages derived from my foregoing invention are
1. The chain of a Cycle can be adjusted without altering the bearings.
2. The bearings can be adjusted without altering the chain.
.3. It gives greater facility for removing the back wheel and returning same
without altering the chain adjustment.
4. The hind wheel is always kept central in back forks of the frame.
5. It ensures a firmer connection between the frame and the back wheel spindle.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The hereinbefore improved means or appliances for facilitating the adjust-
ment or strain of cycle chains i.e. an entering plug and a clipping device arranged
for operation as described.
2. The combined appliances, i.e., the clipping device and the setting device.
as illustrated, and employed in conjunction on or to the same cycle machine as
desired.
