PROVISIONAL SPECIFICATION.
Improvements in Devices for Tightening Up and Securing the
Fixing Wires of Wheel Tires.
I, ALFRED MACDONALD of 46 Whitehill Street, in the City and County of
Glasgow, Cycle Engineer, do hereby declare the nature of my invention to be as
follows:-
This invention has reference to and comprises improved simple and efficient
devices for tightening up and securing the ends of the fixing ring wires of cycle or
other wheel tires.
By my improvements I secure the two adjacent ends of the tyre securing wires
I fit a
each in a crosshead or collar preferably by screwing the ends into same.
screw threaded spindle or pin to pass through screw threaded eyes in both cross
heads and I form a socket or like head at one end of screw spindle for turning same,
but the turning would preferably be done by inserting the key end of a portable
handle into the socket and turning the handle. By this means the two crossheads
can be brought to approach each other and so tighten the wire or the reverse
turning will make them recede and so slacken the wire. If desired the hand lever
instead of being portable may be formed in one piece with the screw spindle or its
socket head, and lie close to the tire. This device will be found to be more simply
and efficient than the right and left handed screw threaded spindles and sockets
heretofore in use.

Improvements in Devices for Tightening Up and Securing the
Fixing Wires of Wheel Tires.
I, ALFRED MACDONALD of 46 Whitehill Street in the City and County of
Glasgow, Cycle Engineer, do hereby declare the nature of my invention and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement in writing, that is to say :-
This invention has reference to and comprises improved simple and efficient
devices for tightening up and securing the ends of the fixing ring wires of cycle or
other wheel tyres.
And in order that my said invention and the manner of performing or carrying
same into practice may be properly understood, I have hereunto appended an
explanatory sheet of drawings in which
Figure 1 is an elevation partly in section showing my improved device as
tightening up the two ends of a wheel tyre fixing wire, and
Figure 2 shows a view of the operating tool.

page_text: Referring to these drawings:
By my improvements I secure the two adjacent ends a, a of the tyre securing
wires each in a crosshead or collar b, 6, either by forming these crossheads b, b¹ in
one piece with the wire as shewn, or by soldering or otherwise securing them
thereto.
I fit a screw threaded spindle or pin to pass through screw threaded eyes at 62
in both crossheads b, the threads on one half of spindle e being preferably formed
right handed and those on the other half left handed as shown in Figure 1 ; and
1 form a square or like head c' at the end of screw spindle c for turning same, but
the turning would preferably be done by inserting the socket end d' of a portable
hand tool d on to the square end e¹ of spindle and turning same. By this means
the two crossheads b, b¹ can be brought to approach each and so tighten the wire a, a¹
or the reverse turning of the spindle c will make them recede and so slacken the
wire. If desired the hand lever instead of being portable may be formed in one
piece with the screw spindle c or its square head and lie close to the tire.
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
A device for tightening up and securing the fixing wires of wheel tyres.
constructed and operated substantially as herein described in reference to and
sbown in the accompanying drawings.
Dated 23rd day of November 1895.
