between Jack Levers and Blades of Wytch Engines.
We, FREDERICK NICOLADIES PRIESTLEY of Victoria Mills, Liversedge, in the
County of York, Woollen Manufacturer, and MAHLON HIRST of the same place,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to connect or join the horizontal reciprocating jack
levers with the vertical jack blades used in wytch engines in such a manner that a
greater amount of support is given to the sides of the bottom portion of the jack
blades for the purpose of retaining the blades in their vertical path and thereby to
preserve the engine needles, and to su form the joints that no rivetting is required,
and a larger wearing surface obtained than those of the ordinary construction.
We accomplish our object in the following manner: The end of each jack lever we
form with a slot hole passing through same in a vertical direction and form at the
end a circular distance piece which acts as a stud, the back portion of the slot hole
being curved from the same centre as the distance piece.
The bottom end of the jack blades we curve in such a manner that each will pass
through the slot hole in the levers, the sides of the said slot hole keeping the blade
vertical, and the distance piece acting as a stud engages with the curved end of the
blade, the same being kept in easy working position by the curved back end of slot
hole, thereby enabling the lever and blade to work easily with a minimum amount
of clearance between the working surfaces.

We, FREDERICK NICOLADIES PRIESTLEY of Victoria Mills, Liversedge, in the
County of York, Woollen Manufacturer, and MAHLON HIRST, of the same place,
Engineer, do hereby declare the nature of this invention and in what manner
the same is to bo performed, to be particularly described and ascertained in and by the
following statement :-
The object of this invention is to connect or join the horizontal reciprocating
jack lovers with the vertical jack blades used in Wytch engines, so that more support
is given to the sides of the bottom portion of the jack blades for the purpose of
retaining the blades in their vertical path, and thereby preserve the engine needles,
and to so form the joint that no rivetting is required in its construction; and consists
in forming the bottom end of the jack blades curved in such a manner as to pass
through a slot hole prepared in each jack lever, and therein engage with a circular
distance piece which acts as a stud, whereby the said blades are operated and kept
vertical.
In order that this invention may be better understood we will further describe the
same by making reference to the accompanying sheet of drawings in which Fig. 1.
represents a view of a jack lever having a jack blade attached thereto by our
improved joint. Fig. 2. is a plan of same, and Figs. 3 & 4. are details drawn to a
larger scale.
At one or both ends of each jack lever A, we form a slot hole B, passing through
same in a vertical direction, and in the said slot hole we form a circular piece C,
which acts as a stud; the back portion of the slot hole at B¹ being curved, struck
from the same centre as the circular distance piece or stud C.
The bottom end D³, of each jack blade D, we curve or form hook shaped, in such
a manner and of suitable width as will enable it to pass through the slot hole B, in a
lever A; the sides of the said slot hole keeping the blade D vertical, and the circular
distance piece C acting as a stud, engages with the curved end D1 of the blade D,
thereby forming a joint kept in working contact with the stud C, by the curved slot
hole, thus by these means, a connection between the horizontal and vertical jack
levers and blades is obtained, having a large wearing surface, and the vertical blades
when in working position being kept in their relative paths with a minimum amount
of clearance.

page_text: Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The herein before described means of connecting the horizontal levers and vertical
blades used in Wytch engines; the essential novelty in such consisting in forming a
slot hole through the lever having a curved end and a circular stud therein; and
forming the end of the vertical blades with a hooked end to engage in the slot hole,
all substantially in the manner as shown and described.
