page_text: LETTERS PATENT to William Wrest, of Leeds, in the County of York, for the
Invention of "IMPROVEMENTS IN THE MEANS OR APPARATUS EMPLOYED FOR
STAKING, SETTING OUT, AND BOARDING OR SOFTENING LEATHER."
Sealed the 15th September 1877, and dated the 24th March 1877.
PROVISIONAL SPECIFICATION left by the said William Wrest at the Office
of the Commissioners of Patents on the 24th March 1877.
"
WILLIAM WREST, of Leeds, in the County of York. IMPROVEMENTS IN THE
MEANS OR APPARATUS EMPLOYED FOR STAKING, Setting OUT, AND BOARDING OR
SOFTENING LEATHER.”
On suitable framework I mount two pairs of drums or pulleys, one above the
other, and at any required distance apart. Over each pair is passed a belt or sheet.
To each belt or sheet are fixed projecting rubbers, which may be made of metal,
wood, or other suitable. material.
A rotary motion is imparted to the lower pair of drums or pulleys, causing tho
sheet or belt which carries the lower projecting rubbers to travel in a horizontal
direction.
A traversing motion is imparted to the upper travelling sheet by the projecting
rubbers of the lower travelling sheet or belt acting during its motion upon the
projecting rubbers of the upper travelling sheet or belt.
The leather to be operated upon is mounted on a table (to which may be either
imparted a parallel or radial motion), and in such a position with regard to the
projecting rubbers that it passes in between the same; a suitable pressure is obtained
upon the leather by retarding the progress of the upper sheet; this may be done by
a suitable brake upon the upper pair of drums or pulleys, or by other equivalent
means.
By the frequent passage of the leather between the projecting rubbers, and by
varying the construction of the rubbers, the staking, setting out, and boarding or
softening operations may be performed. A clamp appliance is employed for retaining
the leather in position. By the above arrangement of machinery there is a great
saving of time and labour; also the work is done much better than by hand, or by
machines of ordinary construction.

the leather in position. By the above arrangement of machinery there is a great
saving of time and labour; also the work is done much better than by hand, or by
machines of ordinary construction.
And in order that my Invention may be more completely understood reference
is given to the accompanying Sheet of Drawings, and to the letters and marks of
reference thereon.
DESCRIPTION OF DRAWINGS.
Figure 1 represents a side clevation; Figure 2, a front elevation; and Figure 3,
a plan of a machine constructed according to this Invention.
Over
On suitable framework a I mount two pairs of drums or pulleys band b, c and c¹..
The pulleys band b¹ are on the shafts d, which are mounted in the bearing e on the
framework a, and over or above the pulleys c and c. The pulleys c and c² are on
the shafts f, which are mounted in suitable bearings g on the framework a.
the upper pulleys band b¹ is passed the belt or sheet h, and over the lower pair of
pulleys c and c¹ is passed the belt or sheet i, and in order to give the required
tightness to the belts or sheets I provide the set screws J and J¹, whereby the
distance between the pulleys is regulated.
To the upper and lower sheets are attached the brackets and ; to the
brackets are attached the rubbers or knives l, which may be of metal or other
suitable material, and on the brackets k¹ are mounted the rollers m; instead of
these rollers m another set of rubbers, like those shown in l, may be employed. A
rotary motion is imparted to the lower pulleys c and c¹ through driving pulley n
from suitable motive power, causing the sheet or belt i, which carries the lower
projecting rubbers or knives 7, to travel in a horizontal direction. A traversing
motion is imparted to the upper travelling sheet or belt h by the projecting rubbers,
or knives of the lower sheet i, acting during its motion upon the projecting
rubbers m of the upper sheet h. It will be readily understood that each lower
rubber or knife, coming behind a corresponding upper roller or rubber, pushes it
forward, giving thereby the required horizontal traverse.

page_text: The leather to be operated upon is in some cases mounted on a table (to which
may be imparted a parallel or radial motion), and in such a position that it (the
leather) passes in between the same.
In my Drawings I have shewn a long roller o mounted on the sliding brackets p...
The material is, in the first place, put on the roller, and held in position by means
of the rope q, and in order to give the required firmness I pass the leather round
the roller one or more times. After the leather has been wound round the roller o
it (the roller) is retained in position by means of the ratchet and pawl arrange-
ment v.
The mode of applying the leather is as shewn at w, Figure 1.
Any convenient clamp arrangement may be employed for holding the leather in
position. A suitable pressure is obtained upon the leather passing between the
rubbers by retarding the progress of the upper sheet h; this may be effected by
means of the brake r, which is actuated by the attendant through the hand lever s
and arm t carried in bearings u. Other equivalent means may be employed for this
purpose.
Having now described the nature of the said Invention, I would have it understood
that I do not limit myself to the exact details or configuration of the various parts
I have explained and shewn, as the same may be varied or modified, without in any
way departing from the nature or principle of my Invention, but what I claim and
desire to be secured to me by Letters Patent is,-
First. The arrangement, construction, and application of lower rubbers or knives /
and upper rollers or rubbers m, or any mere modifications of the same, acting in
conjunction upon leather, substantially as and for the purposes herein set forth.
Second. The arrangement, construction, and combination of the various parts
forming the machine, substantially as herein set forth.
In witness whereof, I, the said William Wrest, have hereunto set my hand
and seal, this Eighteenth day of September, in the year of our Lord One
thousand eight hundred and seventy-seven.
