IMPROVEMENTS IN OR APPLICABLE TO LOOMS FOR WEAVING
Year: 1876

page_text: LETTERS PATENT to Joseph Holding, of Manchester, in the County of Lancaster,
Engineer, for the Invention of "IMPROVEMENTS IN OR APPLICABLE TO LOOMS
FOR WEAVING."
Sealed the 27th April 1877, and dated the 1st November 1876.
PROVISIONAL SPECIFICATION left by the said Joseph Holding at the
Office of the Commissioners of Patents on the 1st November 1876.

PROVEMENTS IN OR APPLICABLE TO LOOMS FOR WEAVING."
My Invention relates to the treddles of looms, and has for its principal object, to
render their action on the healds less violent and injurious. To this end I in the
first place transmit the thrust of the tappit from the treddle bowl to the treddle
lever through a spring, or through springs bearing or acting either directly or in-
directly upon the periphery of the bowl or upon the gudgeons thereof. In the
second place I make the said treddle bowl of wood or I make the periphery thereof
of wood, or I cover the said periphery with buffalo hide or I make the body of the
bowl of buffalo hide.
The covering of buffalo hide may be secured to the bowl by means of wooden pegs
or by other suitable means. When the body of the bowl is made of buffalo hide,
rings of hide may be riveted or secured together or be threaded upon a spindle and
be clamped together with a uut, the united pieces of hide being turned to the
required form and size.

My Invention relates to the treddles of looms and has for its principal object, to
render their action on the healds less violent and injurious. To this end I in the
first place transmit the thrust of the tappit from the treddle bowl to the treddle
lever through a spring, or through springs bearing or acting either directly or in-
directly upon the periphery of the bowl or upon the gudgeons thereof. In the
second place I make the said treddle bowl of wood or I make the periphery thereof
of wood, or I cover the said periphery with buffalo hide or I make the body of the
bowl of buffalo hide.
The covering of buffalo hide may be secured to the bowl by means of wooden pegs
or by other suitable means. When the body of the bowl is made of buffalo hide,
rings of hide may be riveted or secured together or be threaded upon a spindle and
be clamped together with a nut, the united pieces of hide being turned to the
required form and size.
And in order that my said Invention may be fully understood, I have appended
hereunto a Sheet of Drawings made about the full size and marked with letters of
reference, to which Drawings I will now refer.
Fig. 1 represents so much of a treddle as is necessary for the illustration of the
first part of my Invention. In the said Fig. a is a portion of a treddle which is
formed with a slot in which is mounted a bowl b as is usual; a spring c is attached
by one end to the lower side of the treddle, the other end of the said spring bearing
against the said bowl. It will be seen that the said spring raises the gudgeons of
the said bowl from contact with the bearings in which the said gudgeons ordinarily
revolve. When the tappit acts upon the said bowl the force exerted thereupon is
transmitted through the spring to the treddle, whereby the harness is relieved from
excessive shocks, and the action of the parts is rendered less severe.
Fig. 2 represents a modification of the foregoing arrangement, Fig. 3 being a
vertical section on the line A in Fig. 2. In this example the gudgeons of the bowl
rest in bearings formed in a step frame d, which is fitted to slide up and down in
slots formed in the treadle; the frame d is acted upon by a spring e which tends to
force the said frame upwards. In this example the force exerted by the tappit is
transmitted through the frame d to the spring and from the spring to the treddle, the
effect being similar to that of the example illustrated by Fig. 1, but in the second
example the friction of the spring upon the periphery of the bowl is obviated.
Other modifications may be made without departing from the intent of my
Invention, as for example, two springs may be arranged to sustain the bowl, and if
preferred each spring may act upon a gudgeon of the bowl.
Fig. 4 illustrates the second part of my Invention and represents a vertical section
of a treddle bowl. In this example discs of buffalo hide f are placed upon a
spindle which is formed with a collar and are secured by tightening a nutth. The
collective edges of the said discs are turned to a circular form, and the bowls so
formed are employed in lieu of metal bowls in the improved treddles illustrated or
in ordinary treddles. When forming the said bowls of wood I prefer to use lignum
vitæ or other similar wood; In some cases I cover the peripheries of the said bowls
with buffalo hide as herein-aforesaid.
Having now fully set forth and indicated the nature of my said Invention and
the manner in which I carry the same into practical effect, I would have it to be
understood that I claim,-
First. The employment of springs, substantially as and for the purpose set forth

page_text: Secondly. The arrangement substantially as and for the purpose set forth and
indicated herein-before, and by the Figures 1, 2, and 3 of the accompanying
Drawings.
And, Lastly. The methods of forming bowls for treddles herein-before set forth.
In witness whereof, I, the said Joseph Holding, have hereunto set my hand
and seal, this Twenty-eighth day of April, in the year of our Lord One
thousand eight hundred and seventy-seven.
Signed and sealed by the said Joseph
Holding, in the presence of
