Year: 1873

page_text: LETTERS PATENT to Joseph Merritt Lambert, Manager to George
Angus and Company, of Newcastle-upon-Tyne, Leather Band and
Hose Pipe Manufacturers, for the Invention of " IMPROVEMENTS IN
THE MANUFACTURE OF LEATHER HOSE AND OTHER RIVETTED LEATHER GOODS,
PROVISIONAL SPECIFICATION left by the said Joseph Merritt Lambert
at the Office of the Commissioners of Patents, with his Petition,
on the 26th July 1878.
I, JOSEPH MERRITT LAMBERT, Manager to George Angus and
Company, of Newcastle-upon-Tyne, Leather Band and Hose Pipe
Manufacturers, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF LEATHER HOSE AND
THEREIN to be as
RIVETTED LEATHER GOODS, AND IN APPARATUS EMPLOYED

OTHER
Hitherto the rivet holes in leather to be made into hose, fire buckets,
and other articles have been formed by hand tools, an operation which is

page_text: Now my Invention consists in punching the holes by means of an
apparatus specially constructed for the purpose.
This apparatus is composed, firstly, of a pair of fluted or plain rollers,
caused to rotate by hand or other power, between which rollers the
leather to be punched is placed, and by which it is fed in a regular
manner to the punches.
Secondly. Of a pair of punches and dies, one for each edge of the
leather, the said punches and dies or one punch and die being adjustable
in any ordinary manner, so that the apparatus can be adapted to the
width of the leather to be punched. I prefer that the punches for the
two edges should be worked simultaneously and in a vertical direction,
but they may be worked alternately and horizontally, or in an inclined
direction.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Merritt Lambert in the Great Seal Patent
Office on the 26th January 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
MERRITT LAMBERT, Manager to George Angus and Company, of
Newcastle-upon-Tyne, Leather Band and Hose Pipe Manufacturers, send
greeting.
:
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of July, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Joseph Merritt Lambert, Her special
licence that I, the said Joseph Merritt Lambert, my executors, adminis-
trators, and assigns, or such others as I, the said Joseph Merritt Lambert,
my executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF LEATHER HOSE AND OTHER RIVEITED LEATHER GOODS, AND IN
APPARATUS EMPLOYED THEREIN," upon the condition (amongst others) that
I, the said Joseph Merritt Lambert, my executors or administrators, by

page_text: some of the gearing. The same letters of reference indicate the same
parts in all the Figures.
A is the framing of the machine, supporting a table B, two fixed
standards C, O, and an intermediate standard O³, the position of which is .
adjustable in a slot D in thetable, so as to accommodate itself to various
widths of leather to be operated upon; E is a driving shaft, working in
suitable bearings in the framing A, and carrying at one end driving
sheaves F, F, and at the other end a hand wheel G. On the driving.
shaft E are two excentrics H, H, from which two connecting rods I, I,
are respectively carried up to strong pins K, Ķ. These pins K, K, are 1
fitted into blocks L, L, which are free to be moved vertically on their
respective standards C, C, O¹, to which they are dovetailed, as seen in
Figure 1. These blocks L, L, carry steel punches M, which are held in
place by means of screw bolts N, N. O is a longitudinal bar passing
through the blocks L, and carrying awl blocks P, to which, awls Q are
-fixed. R, R, are gouges. fitted in blocks R', R', carried respectively on
upper and lower gouge shafts S, S. T, T, are feed rollers carried by
spindles U, revolving in the standards O, O', to the lower of which
spindles an intermittent motion is imparted by means of a ratchet
wheel V thereon, and a paul V¹ mounted on a plate W, this paul being
operated from one of the connecting rods I by means of a rod X, as-
clearly seen in Figure 4. Y, Y, are toothed wheels for transmitting-
motion at the same speed from the lower to the upper spindle U. Z, Z,
are feed discs carried by spindles a, revolving in brackets 6, to the lower
of which spindles an intermittent motion is imparted by means of a
ratchet wheel c thereon and a paul c¹ mounted on a plate d, this paul
being operated from one of the connecting rods I by means of a rod e, as
clearly seen in Figure 4. f, f, are toothed wheels for transmitting.
motion at the same speed from the lower to the upper spindle a. 9,9,
are guides, adjustable by means of a slot h, to guide the leather into the
machine. (Figure 3) represents one of the steel dies corresponding to
the punches M. Guards / prevent the leather rising with the punches.
Similar guards prevent the leather rising with the awls. m, m, are
levers, by means of which the gouge shafts S can be moved so as to clear
the gouges of the leather when passing over a joint. The gouge blocks R¹
and the feed discs Z are adjustable so as to suit the number and position
of the grooves in each belt. n, n, are springs to give the spindles U a
little freedom in their standards in order to suit different thicknesses of
leather. o is a slot in the table B to allow the punching to fall through;

page_text: p is a plate which is inserted to cover the gouges R and the discs Z, and
to form a level surface when thin leather for hose piping is being
operated upon. q represents the position of the leather while being
punched.
Such being the construction of the apparatus the action is as follows :—
Supposing it is intended to punch holes in leather for hose piping the
plate d, Figure 4, with the paul o' is shifted to the under side of the
bearings, the plate p is inserted, as above stated, the gouges R are moved
clear by means of the levers m, and the awls Q are removed. The end
of the leather to be punched is then inserted, and the apparatus being
put into operation an up-and-down movement is given to the punches by
means of the connecting rods I, which work the blocks L, while the
leather is moved forward intermittently by means of the intermittent
motion imparted to the feed rollers T by the ratchet wheel V and
paul V. The distance to which the leather is thus moved each time
must of course be equal to the distance required between the holes.
When it is required to pierce awl holes and to form grooves in the
leather in the lines of the rows of awl holes, the punches are removed,
and also the plate p, the awls are inserted, the gouges are moved into
position by the levers m, and the plate d and paul c¹ are returned to
position, the operation may then proceed, the leather being fed inter-
mittently by the discs Z, while the awls are moved up and down with the
blocks Land bar O.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim,-
First. Forming holes in leather by mechanical means, substantially in
the manner and for the purpose herein-before described.
Second. Constructing apparatus substantially as and for the purpose
