PROVISIONAL SPECIFICATION.
An Improvement in or for Hand Tool or Machine used in Making
Pile Fabrics on a Foundation (Mats, Rugs, Trimmings, and like
articles).
I JOHN WHITFIELD of 24 The Avenue Wallsend, in the County of
Northumberland, Agent do hereby declare the nature of this invention to be as
follows:-
:―
as
The application of a screw or its equivalent in order to regulate what is terme l
the stitch carrier" in John Whitfields Patent Number 12175 93 and dated
June 21st. By regulating I mean raising or lowering the "stitch carrier"
required to place the loop (pile or stitch) either closer together or wider apart.
To secure the object in view I place the screw (or its equivalent) in any suitable
position under the "stitch carrier" but by preference I place it exactly under the
spring so that when screwed or placed into position it will be found to have passed
up the inside of the spiral spring (it can also be used to support a flat spring) anl
so reaching the "stitch carrier when by simply raising or lowering the screw (or
equivalent) the "stitch carrier" is raised or lowered correspondingly, thus securing
the object in view, namely the placing of the pile, loop or stitch either closer
together or wider apart according to the desire of the operator. It also lengthens
or shortens the loop.
Dated this 29th day of November 1894.

An Improvement in or for Hand Tool or Machine used in Making
Pile Fabrics on a Foundation (Mats, Rugs, Trimmings, and like
articles).
1, JOHN WHITFIELD, of 24 The Avenue, Wallsend, in the County of
Northumberland Agent &c. 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 :—
A. B. Fig. 1. is referred to in my Patent No. 12175,93 as the "stitch carrier."
It will be noticed by referring to my Specification 12175,93 that the said
"stitch carrier" is only capable of a limited rise and fall according to the depth of
space in the groove in which the carrier works.
Now by applying the screw in the manner which I shall presently describe, I am
enabled to considerably deepen the groove or if necessary to carry it right through
as shown at C D. Fig. 2. Having done away with the bottom of the groove in
this case, I select a screw, cither ordinary or thumb screw, in fact any screw of
sufficient length and thickness to find sufficient purchase on the sides (or through
the bottom) of the groove to form a sufficient support for the carrier to rest upon
as shown at E. F. Fig. 1.

page_text: G. H. Fig. 1. is the spring described in Specification 12175 93. The regulating
or supporting screw may be so placed as to pass up through the inside of the spiral
spring and so reach the carrier as shown at E. F. Fig. 1, or it may be placed in
any other convenient position outside of the spring as shown at J K. Fig. 3. Now
from this arrangement it will be perfectly clear chat by raising or lowering the
screw E. F. Fig. 1. or J. K. Fig. 3. the carrier A. B. Fig. 1, or L. M. Fig. 3. will
be, or can be lowered or raised to any required angle, necessary in working the
machine; and in the hands of the operator, the carrier as influenced by the spring
will accommodate or adjust itself to whatever distance the screw has been lowered or
raised; and thus secure a closer or wider stitch and thereby increase or decrease
the length of loop in a manner which was not possible by the arrangement carried
out in Specification 12175/93; and this I claim is a distinct and novel improvement
which adds considerably to the utility of the tool or machine to which it may be
applied.
The screw arrangement will be equally effective if a flat spring be used as a
carrier, or be placed underneath the carrier instead of the spiral spring.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is.
1. The application of the principle contained in a screw or its equivalent to and
for the purpose as substantially described in the above Specification.
Dated this 22nd day of August 1895.
JOHN WHITFIELD.
