PROVISIONAL SEMIFICATION.
Improvements in Machines or Apparatus for Covering Rollers or the
like with Leather or similar Material.
We, EDWIN GAUNT, of Grangefield Mill, Stanningley, in the County of York,
Manufacturer, and WILLIAM FIRTH, of Cavendish Place, Stanningley, aforesaid,
Mechanic, do hereby declare the nature of this invention to be as follows :-
This invention relates to improvements in machines or apparatus for covering
rollers or the like and particularly for covering with leather the rollers used in
machines for drawing, spinning and twisting fibrous material.
For this purpose we mount the roller by its spindles or arbor in vee bearings
formed in two standards mounted on a bed plate and adjustable in relation to each
other. An adjustable cross slide is fitted preferably above the said standards and
two arms or stretchers are mounted thereon one on each side above said standards
and capable of being adjusted in relation thereto and to each other by means of a
right and left hand screw. A number of short pins are fitted in the ends of said
arms or stretchers.
In operation the roller to be covered is mounted in the vee bearings and a piece
of leather cut approximately to the proper length and covered with glue or cement
is passed round it in such a manner that the said stretchers may be brought down
upon the leather close to the ends by adjusting the said cross slide. The stretchers
are then brought towards each other and the pins therein engaging the ends of the
leather draw the ends with them thus bringing such ends together as well as tightly
stretching the leather round the roller. The ends of the leather are pinned or
clamped in this position and the roller is then withdrawn from the machine.

Improvements in Machines or Apparatus for Covering Rollers or the
like with Leather or similar Material.
We, EDWIN GAUNT, of Grangefield Mill, Stanningley, in the County of York,
Manufacturer, and WILLIAM FIRTH, of Cavendish Place, Stanningley, aforesaid,
Mechanic, 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 improvements in machines or apparatus for covering

For this purpose we mount the roller by its spindles or arbor in vee bearings

two arms or stretchers are mounted thereon one on each side above said standards
and capable of being adjusted in relation thereto and to each other by means of a
right and left hand screw. A number of short pius are fitted in the end of said
arms or stretchers.
In operation the roller to be covered is mounted in the vee bearings and a piece

are then brought towards each other and the pins thereon engaging the ends of the
leather draw the ends with them thus bringing such ends together as well as tightly
stretching the leather round the roller. The ends of the leather are pinned or
clamped in this position and the roller is then withdrawn from the machine.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents a front elevation of our improved apparatus.
Figure 2, is a plan view of the same with a portion of the bed plate cut away
to economise space, and
Figure 3, is a sectional elevation on the line a, b Figure 1.
The roller to be covered is loosely mounted by its arbor in the vee bearings A.
formed in two standards B and B' secured upon the bed plate C by the bolts D, D'
in the slot E. The standard B is provided with hinge or knuckle hinge E to
-enable it to be bent forward to facilitate placing the roller in position and removing
it therefrom. The two arms or stretchers G, G are mounted in the saddles H, H
mounted upon the cross slide J and are adjusted in relation to each other by the
left and right hand screw K and hand wheel L. The cross slide J is mounted
upon the vertical slide M formed on the standard N secured to the bed plate C and
is adjusted vertically by the screw O and hand wheel P. A number of short
pins are fixed in the vee pieces R secured in the feet S of the arms G.
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:
A roller covering machine having two adjustable arms or stretchers adapted to
be simultaneously brought to bear upon the leather or other covering material and:
stretch it round the roller as the leather is loosely mounted adjacent to them,
substantially as herein shown and described and illustrated in the accompanying
-drawings.
