page_text: PROVISIONAL SPECIFICATION.
A Machine for Fixing and Drilling the Main Tubes of a Cycle Frame,
We, SAMUEL ALBERT JACKSON, of 153, Regent Road, Salford, Lancs, Cycle
Manufacturer, and WILLIAM HENRY JACKSON, of 78, Oxford Street, Salford, Lancs,
Cycle Manufacturer, do hereby declare the nature of this invention to be as
follows:-
A plate frame fitted with adjustable brackets for the purpose of fixing and
retaining the tubes connected to the ballhead, bracket and seat lug in a cycle frame,
until drilled and pegged, with each tube in an horizontal, or vertical plane.
In combination with a radial arm drill, supported by a vertical or upright pillar
at or about the centre of the plate frame. The said drill being locked in position
or released to be set in any other position by tightening or slackening one bolt
or screw.
Dated this 5th day of December 1898.

A Machine for Fixing and Drilling the Main Tubes of a Cycle Frame.
We, SAMUEL ALBERT JACKSON, of 153, Regent Road, Salford, Lancashire, and
WILLIAM HENRY JACKSON, of 78, Oxford Street, Salford, Lancashire, Cycle Makers,
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 the construction of apparatus which shall enable
a cycle frame to be built with greater accuracy, and in less time than has hitherto
been practicable.
In the drawings hereunto annexed, Fig. 1 is a plan view, and Fig. an elevation
of our improved machine.
A is a plate frame casting machined true on the face, which may be mounted
upon a stand, or otherwise; rising from this plate frame A, we mount the adjust-
able stud B fitted with nuts H for the purpose of receiving the bracket of the
cycle. Rising also from the plate frame A is the adjustable bracket C for sup-
porting the seat tube and the adjustable brackets D for supporting the
ball head, the said stud B, and brackets C and D, being for the purpose of
fixing the cycle frame with each tube parrallel and the bracket exactly at
right angles to the tubes. From a pillar E, rising at or near the centre of
the plate frame A, we mount the radial arm drill F, which is locked in position
by the bolt or screw G.

page_text: The method of using this improved machine is as follows. The tubes and lugs
forming a cycle frame are first assembled, then the bracket of such frame is
placed upon the stud B and is held in position by the nuts H, the seat lug and
ball head are then supported by the adjustable brackets C and D, thus fixing
the frame true; then the drill is brought over cach lug as required, and the holes
drilled for the reception of the steady pins; the steady pins are then inserted
in the holes. The cycle frame is then removed from the machine and is ready
for brazing.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed; we declare that what
we claim is:-
Firstly; The combination of plate frame and drill, substantially as herein before
described and illustrated.
Secondly: The drill F secured in position for drilling by the bolt or screw G.
Thirdly The brackets C and D and stud B with nuts H in combination with
frame A substantially as and for the purposes herein before described and illus-
trated.
