COMPLETE SPECIFICATION.
Improvements in Reciprocatory "Pegging" Machines employed in
the Finishing of Pile Fabrics.
We, HARVEY HEYWOOD, of Spring Vale Works, Middleton, near Manchester,
Manufacturer, and JOHN HOLLAND, of Spring Vale Works, Middleton, near
Manchester, Foreman 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 :-
32
The improvements relate to what are known in the trade as "pegging machines,"
employed in the finishing of pile fabrics, and refer, more especially, to pegging
machines wherein a reciprocatory motion is given to the "peg" or presser bar;
and such improvements have for object the attainment of a higher speed of action, as
well as greater facility in disconnecting, rolling, and removing the lengths of cloth
when such have undergone, and require to have repeated thereon, the necessary
process of "pegging.
To accomplish this, and to effect our improvements, we provide apparatus as
shewn in the accompanying drawings, wherein
Fig. 1 is a plan view, and Fig. 2 a side elevation of our improved "pegging'
machine.
32
a. a is a frame, on which we mount a horizontal bed-plate . b. capable of being
raised or lowered in position by partial revolution of the eccentric supports c. c.,
and over which bedplate, the cloth d. d. is caused to travel.
Below the centre of this bed plate, is transversely situated a rocking bar e. e.
turning in suitable journals, upon which bar are pivotted rocking levers which
oscillate in a direction parallel to the motion of the cloth.
The upper portions of these levers are caused to actuate a second transverse
rod g. g., carrying the "peg" or presser bar h. h. and supported at the ends by the
sliding sockets . k., which slide longitudinally on shafts or rods 1. 1. held by
standards m. m., attached to the main framing of the machine.
"
To regulate the pressure of the "peg. on the cloth, we provide, by preference,
suitable spring mechanism n. n. at each termination of the shafts or rods l. l.,
which mechanism is capable of adjustment by worm and wheel, as shewn, or by
other means, operating at each point of support, so that the tension on the shafts l. 1.
is evenly imposed or released, and causes the " peg" or presser bar to bear, with
uniformly elastic pressure, upon the cloth.
A stop or stops may be provided, to prevent the presser bar from being borne,
by pressure against the fabric under operation, beyond the desired angle of
resistance.
In operation, the oscillating levers f. f. are caused to rock, by crank motion, as
shewn, or by other means, upon the rocking shaft e. e., and, in their turn cause the
sliding sockets k. k. to slide to and fro along their respective shafts, carrying with
them the presser bar h. h., which, pressing the cloth between its surface and that of the
bed-plate b. ., imparts to the fabric the required finish.
The cloth may receive the required tension by suitable tension rollers weighted,
or otherwise allowed to drag, and passes, after the "pegging" operation, to the
rolling and detaching apparatus which forms the second portion of our
improvements.
This apparatus in part consists of a pair of two-armed levers o. o., fulcruned at
their centre, and rendered capable of swinging easily upon a rod p. p. mounted
transversely at the back of the machine.
The extremities of the arms of these levers are formed as journals, to receive the
ends of the spindles of the cloth rollers.

page_text: When the cloth is in motion, the levers assume a vertical position, as shewn, the
upper journals thereof supporting the roller q. q, which receives the cloth from
the machine.
The spindle of such roller is connected, by suitable means, to a strap pulley r. r.,
or other conveyer of motion,, to enable the fabric to be taken up as it is delivered,
and may be disconnected at will, in this case, by operating the clutch s. s., but
other modes of disconnection may be employed.
As soon as the roll of cloth is completely wound, the machine may be stopped,
and the levers o. o. are swung round on the pivot p. p., till their position is reversed,
the full roll of cloth occupying the lower journals, and the upper bearings carrying
an empty roller to receive the next length of fabric.
As the machine is set in motion again, the winding on process is repeated, and, at
the same time, the first roll of cloth-now temporarily connected with the lower strap
pulley t. t. is unwound on to a disconnected roller, by frictional means, as shewn,
or by other means, thus leaving the roller empty for a further winding at the next.
reversal of the swing levers o. o., and allowing the cloth to be transferred to the
front end of the machine, or to be carried away, with facility.
<
Variations in detail may be made, such as in the method of attaching and
driving the oscillating levers f. f, and in the method of adjusting the pressure on
the presser bar or peg," and more than one bed-plate, "peg," and accompanying
apparatus may be employed; likewise the method of actuating the winding and
detaching apparatus, as well as the detail of its parts, may be varied, without
departing from the peculiar character of the invention.
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. In reciprocatory "pegging" machines, the combination of a horizontal bed-
plate b. b., capable of being raised or lowered, with a horizontally reciprocating
peg or presser bar h. h., having adjustable pressure apparatus, for the purpose
and in manner substantially as herein shewn and described.
22
2. In reciprocatory or the like "pegging" machines, the swinging levers o. o.
for carrying the cloth rollers, which levers o. o. are reversible in position, enabling
the completed roll of cloth to give place to an empty roller, and to take a new
position for unwinding the cloth on to a detached roller, in manner substantially as
herein shewn and described.
