I WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co Patent Agents,
Southampton Buildings, in the County of Middlesex 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 machinery for putting out the grain, and removing the
water or other imperfections from sheep, calf, or other skins, and is hereinafter
described.
In the accompanying drawing,
Figure 1 is a side elevation of the machine complete.
Figure 2 is a side elevation of a portion of the same side of the machine without
the gearing.
Figure 3 is a similar view of the other side of the machine.
Figure 4 is a cross section through the drum.
Figure 5 is a front elevation, and
Figure 6 is a plan or top view.
The frame a of the machine is preferably made of cast iron, and is provided with
bearings a¹ to receive the drum shaft a³, with bearings a³ to support the driving
shaft a, and with bearings a' for the shaft b of the treadles b' and b².
63 63 represent arms projecting from the frame to receive the springs b', which
are connected to the treadles by joints 6', (see figures 1 and 5,) to cause them to
move up when released from the pressure of the foot.
cc represent the putting out cylinders, mounted in bearings c³, c³, on arms c* c³,
fitted to the shaft at so that the shaft can turn in them. They are each provided
with connecting rods d¹, d². The connecting rods dare connected at their lower
ends to crank arms d on the shaft b by pins d' see Figures 1 and 5, and the others
to the treadles by joints d². Their upper ends are connected by joints or pins d³,
to the arms ct, c³.
e represents an india-rubber covered pressure roller shown in figure 6, and in
end view, by dotted lines, in Figures 1, 2 and 3. It is supported in boxes e¹,
(see figure 2,) made adjustable by set screws e³ to adjust its pressure on the skin.
D

page_text: The hollow drum e³ is secured to the shaft a² by a key, and is provided with two
apertures g opening into the interior.
The several parts of the machine receive their movements as follows:-The
pinion gears with and turns the spur-wheel h and the pressure roller e. On the
pressure roller shaft is a pinion i, which gears into the spur-wheel i¹ (carried in a
bracket i) to which is secured a pinion . This pinion gears into the spur-
wheel on the drum shaft, from which the drum receives its rotary motion. The
putting out cylinders receive their movements from a spur-wheel ³ which gears
into the spur-wheels j, j¹.
The operation of the machine is as follows:-
One half of the skin, more or less, is put lengthwise into the drum through the
opening g, so that the other portion hangs outside, and as the drum turns, it is
brought in contact with the putting out cylinders (which are made to act on it by
the treadles) and is operated upon by the first cylinder and passes thence under the
pressure roller, and from that under the second cylinder which takes out any
wrinkles or imperfections that may remain after passing the first cylinder. As the
drum turns another skin is put in in the same way, at the opposite opening g which
is now before the operator, and passes through the same process as the first skin.
It will be seen from this operation that as the drum moves continuously at the
proper speed, so that the operator can put in or take out the skins, that when the
half of two skins is completed and the first skin is brought around to the operator
again, it can be removed and reversed; the half that has been completed is now
inside the drum and the process repeated on the other half of the skin, thereby
completing it. It will also be seen that two skins are in the drum being operated
on at the same time, thereby doubling the capacity of the machine.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated
to me by my foreign Correspondent I declare that what I claim is
First. In a putting out and striking out machine, a hollow drum having two
openings to receive the skins to be operated on, substantially as specified, in
combination with the putting out cylinders, the india-rubber covered squeezing
roller and their operating gearing, substantially as specified.
Second. The combination of a drum having one or more openings to receive a
portion of the skin, and two independently acting putting out and striking out
cylinders and treadles, and their operating gearing, substantially as specified.
Third. In a putting out and striking out machine, a hollow drum having two
openings g directly opposite each other, and means for giving it a rotary motion,
in combination with an india-rubber covered squeezing roller, one or more putting
out cylinders, and mechanism for giving them a rotary motion and a motion to or
from the drum, substantially as described.
Fourth. In a putting out and striking out machine, a continuously moving
hollow drum having an opening, or openings to receive the skin, in combination
with a squeezing roller, one or more putting out cylinders, and mechanism sub-
stantially as specified for giving their rotary movements and for moving the
putting out cylinders to or from the hollow drum, for the purposes described.
