PROVISIONAL SPECIFICATION.
A Spring Tube-holder or Clamp for use in Vices.
1, WILLIAM HENRY JAMES GROUT, of 7, Watson Street, Stoke Newington
Green, in the County of Middlesex, Cycle Engineer, do hereby declare the nature
of this invention to be as follows:-
My invention consists of a pair of metal jaws having various curved grooves or
spaces cut or cast on the face some running parallel and others at angles to the
jaws of the vice so that different sizes of tube can be held in any position. To keep
the jaws in line together a spring is fixed to them and to keep them expanded and
remain on the vice when removing the work. The design of the grooves permit of
holding any hollow work used in the construction of cycles without injury to the
tube or hollow work and in fitting hollow pieces together.

COMPLETE SPECIFICATION.
A Spring Tube-holder or Clamp for use in Vices.
I, WILLIAM HENRY JAMES GROUT, of 7, Watson Street, Stoke Newington
Green, in the County of Middlesex, Cycle Engineer, 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 relates to a spring tube-holder or clamp adapted for fitting the
jaws of any ordinary or parallel vice.
In the accompanying drawings,
Fig. 1 is a side elevation of the inner surface of one portion of the holder or
clamp; the spring which connects this portion with the corresponding portion
being shewn partly in side elevation and partly in section.
Fig. 2 is an end elevation and Fig. 3 a plan of the complete holder or clamp.
In carrying out my invention, I employ a pair of metal jaws A A¹ having various
curved grooves or spaces a, cut or cast on their inner faces; some running parallel
and others at right angles to the jaws of the vice, so that different sizes of tubes
can be held in any desired position. For keeping the jaws in line and connecting
them together, a spring B is used. This spring is preferably fixed to the jaws by
screws, as indicated. In its normal position, the spring is expanded. Conse-
quently, when the vice is screwed up, the spring is compressed, with the result
that, while the vice is being unscrewed, the spring B and jaws A A¹ open out, thus
releasing the work. The jaws and spring remain in the vice after the removal of
the work ready for reuse.
The grooves or depressions, which may be varied to suit particular circum-
stances, permit any tubular work employed in the construction of cycles to be held
without injury.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I claim :-
1. The improved spring tube-holder or clamp, substantially as herein described,
and adapted for fitting the jaws of any ordinary or parallel vice.

page_text: 2. The improved spring tube-holder or clamp, constructed substantially as
described with reference to the accompanying drawings, and comprising jaws A A¹
having grooves or spaces a for the reception and secure holding of the work
without injuring the same, said jaws being connected by means of a spring B and
opening apart on the unscrewing of the vice.
Dated the 8th day of November 1893.
