'Improvements in Apparatus for Operating the Slay
C or Going
Part" of Looms for Weaving.
I WILLIAM JEPSON of Revidge Road, Blackburn in the County of Lancaster
Machinist do hereby declare the nature of this invention to be as follows:-
This invention relates to the use of improved apparatus and means of operating
the slay swords and lay or "going part" of the loom from the tappet shaft so as to
dispense with the crank shaft or employing but one driving shaft.
According to this my invention I mount upon the tappet shaft two eliptical tappets
crosswise or a four leaf tappet-in conjunction with the said tappets is an arm laving
a link at one end which encloses the tappet shaft the opposite ends or sides of the
link having surfaces on which the four leaves or tappets alternately act, the other end
of the arm is attached by its boss to a lug on the slay swords by a through or hinge
pin so that as the shaft revolves the throws or leaves of the tappet will act alter-
nately on the tappet surfaces of the said link and impart through the said link the
required to and fro motion of the slay swords and going parts.

Improvements in Apparatus for Operating the Slay or Going
Part" of Looms for Weaving.
I, WILLIAM JEPSON of Revidge Road Blackburn in the County of Lancaster,
Machinist 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 the use of improved apparatus and means of operating the

page_text: "
slay swords and lay or going part of the loom from the tappet shaft so as to
dispense with the crank shaft, or employing but one driving shaft.
According to this my invention I mount upon the tappet shaft two cliptical tappets
crosswise or a four leaf tappet. In conjunction with the said tappets is an arm having
a link at one end which encloses the tappet shaft, the opposite ends or sides of the
links having surfaces on which the four leafs or tappets alternately act, the other end
of the arm is attached by its boss to a lug on the slay sword by a through or hinge
pin, so that as the shaft revolves the throws or leafs of the tappets will act alternately
on the tappet surfaces of the said link and impart through the said link the required
to and fro motion of the slay swords and going part of the loom.
::
Such being the nature and object of this my said invention, the following is a
description of same reference being had to the accompanying drawings forming a
part of this specification in which Fig. 1 is an elevation of the improved apparatus for
operating the slay sword constructed according to my invention, the tappits and link
being drawn about half size, the slay sword being reduced scale.
The several views on Sheets 2 and 3 are of parts detached in order to shew clearly
their construction.
According to this my invention I mount upon the tappet shaft 1 two eliptical
tappets 2, 3, crosswise, forming a four leaf tappet. In conjunction with the said
tappets is an arm 4 having a link 5 at one end which encloses the tappet shaft, the
opposite ends or sides of the link having surfaces 6, 7, on which the four leafs
A, B, C, D of the tappets 2, 3, alternately act, the other end of the arm 4 is attached
by its boss to a lug 8 on the slay sword 9 by a through or hinge pin, so that as the
shaft 1 revolves, the throws or leafs A, B, C, D of the tappets will act alternately on
the tappet surfaces 6, 7, of the said link, and impart through the said link the required
to and fro motion of the slay swords 9 and "going part" of the loom.
The shoe or end 10 of the link 4 is detachable in order that the tappets may be
introduced thereto being bolted as at 11, 12.
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 ;
The four leaf tappet applied to the tappet shaft of a loom, and the arm and link
4, 5, employed therewith all in combination and for purpose herein set forth, and
substantially as illustrated by the drawings annexed.
