PROVISIONAL SPECIFICATION.
Improvements in Machines for Bending Plates.
HUGH SMITH, Senior, HUGH SMITH, Junior, and OSBOURNE SMITH, Possil
Engine Works, Glasgow, Lanarkshire, Engineers, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to a new and improved combination of parts in
machines for bending iron or steel plates, which machines consist of three rollers
between which the plate is passed.
In order that the nature of our said invention may be properly understood, we
shall now proceed to describe the several figures in the sheet of drawings which we
have hereunto appended.
Fig. 1 is a side elevation;
Fig. 2 is an end elevation, and
Fig. 3 is a section of a portion of machine.
Our invention consists, in the first place, in the application of a beam A to
support the roller B, and in the method of applying and fixing the aforesaid beam A
and roller B-which method is as follows:-
In the two cheeks or frames C. there are two slides D, as shown at one end of
machine in Fig. 1, and these slides are raised and lowered by means of screws E
and nuts F, which nuts are driven by the worm wheels H.
The screws E are attached to slides D by means of the pins K; and the ends of
screws are rounded, and rest in bushes L. The axles M of the roller Bare carried
in the slides D as shown; and the ends of beam A. are fixed to the slides D.
It will thus be seen that we may raise and lower either end of the roller B
and of the beam A, and that the bearings for the axles of the roller B. will always
remain in direct line with the said axles.
The beam A. is made to support the roller B, by means of the small rollers N, as
shown in Fig. 3. We may either fit three sets, or any number of sets, of small
supporting rollers. We may also support the roller B by means of a roller or
rollers having their centres directly above the roller B.
Our invention consists, in the second place, in the application of the steel or iron
tie bars O to support the beams or rails R; which tie bars, passing through the
cheeks or frames C, bind the machine together. The beams or rails R carry
the small supporting rollers S, which support the two long rollers T.

Improvements in Machines for Bending Plates.
HUGH SMITH, Senior, HUGH SMITH, Junior, and OSBOURNE SMITH, Engineers,
Possil Engine Works, Glasgow, in the County of Lanark, 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 reference to a new and improved combination of parts in
machines for bending iron or steel plates, which machines consist of three rollers

page_text: In order that the nature of our said invention may be properly understood, we
shall now proceed to describe the several figures in the sheet of drawings which we
have left with the Provisional Specification.
Fig. 1 is a side elevation, Fig. 2 is an end elevation, and Fig. 3 is a section of a
portion of machine.
Our invention consists in the first place in the application of a beam A. to support
the roller B, and in the method of applying and fixing the aforesaid beam A and
roller B, which method is as follows:-
In the two cheeks or frames C. there are two slides D. as shown at one end of

The screws E. are attached to slides D by means of the pins K, and the ends of
screws are rounded and rest in bushes L.
The axles M of the roller B are carried in the slides D as shown, and the ends of
beam A are also fixed to the slides D.
It will thus be seen that we may raise and lower either end of the roller B. and
of the beam A, and that the bearings for the axles of the roller B. will always
remain in direct line with the said axles.
The beam A. is made to support the roller B by means of the small rollers N, as

tie bars to support the beams or rails R, which tie bars, passing through the

small supporting rollers S, which support the two long rollers T.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The application of beam A. to support roller B.
2. Arrangement of screws E, with rounded ends, resting on bushes L.
3. Application of the steel or iron tie bars O, supporting beams R. & binding the
whole machine together.
