Complete Specification Accepted, 10th May, 1889
We, JOHN WILLIAM KIDDIER, JAMES, KIDDIER and THOMAS KIDDIER, of the
Hosiery Machine Building Company Bell Street and all of the Town and County of
the Town of Nottingham Hosiery Machine Builders do hereby declare the nature of
this invention to be as follows:-
Hitherto it has been the custom to make the face of the slur-cock as employed in
straight bar knitting machines which operates upon the jacks parallel with the face of
the same, the slur-cocks being fastened to or in one piece with the slur bolt and carried
in the slur boxes in the usual way.
When the slur-cock left each jack the sinkers would return suddenly to their
normal position, the sinker occasionally going so far back that the loops would get
over the top of the sinker instead of remaining on the catch of the same consequently
causing damage to the fabric, and, in drawing the loop the needles are sprung out of
position by the thread being forced between the needles by the sinkers.
Now our improvements consist in providing the said slur-cocks with an axis
conveniently fixed in the bolt so that the same are allowed to move slightly to the
right or left as the case may be, sufficient space or play being allowed in the slur box
to permit of the same, the effect of such motion being to prevent the sinkers returning
too sudden and, in a manner cushioning their return so as to prevent the loop from
getting on the top of the sinker instead of remaining on the catch of the same.
Or, instead of employing the swivel bolt as aforementioned we employ a small
slotted sliding piece attached to the slur-cock with inclined or rounded edges for the
same purpose.

page_text: forced the thread e between the needles c¹ the said needles were sprung back in the
direction indicated by the arrow (Fig. 6) and were not allowed-consequent upon
the face of the slur-cock being parallel with them-to recover their normal position
before the slur-cock left the jacks: this amount of spring on the needles, and the sharp
or sudden release of the sinkers frequently being of such nature as to force the
sinkers so far back as to allow the thread to get over the top of the sinker catch d
(Fig. 6) and when the needles c¹ decended to complete the loop they were liable to
break the thread, thus damaging the fabric.
Now by our improvements such evil is obviated: and in forcing the threads between
the needles c¹ by the sinkers L the said needles c¹ are sprung back-though in a much
less degree-and our object in providing that the leading point a of the slur-cock (
shall be more prominent than the point is to enable the said needles to resume
their normal position before the slur-cock has left the jacks which operate upon the
sinkers.
When this course is completed the slur-box returns in the opposite direction-the
jacks having been brought back in the usual way-the slur-cock will move to the
opposite side of the groove H immediately that it strikes the jacks and consequently
the point will be the leading and most prominent point while a will be the
leaving point.
Thus by our improvements in the slur-bolt it will be seen that we cushion the
spring of the sinkers by allowing them to resume their proper position before the
slur-cock leaves the jacks, and also obtain a better fall of the said jacks.
The centre about which the slur-cock moves may be fixed in any part of the
slur-bolt for the same effect.
Or, instead of the aforedescribed means we employ a small slotted piece O (Fig. 5) which
is operated in similar manner, this of course being attached to the slur-cock of a
straight slur-bolt: When commencing a course the slotted sliding piece O is caused
to move to one end of the slot as shown in Fig. 5 upon striking the jacks, and the
slot being sufficiently free on the pins, and the piece O provided with inclined or
rounded edges permit the sinkers to be released less suddenly. A similar action takes
place on the return course bringing the slotted piece to the opposite end of its slot.
A longer motion has necessarily to be given to the slur boxes when using the slotted
piece 8, than in using the swivil slur-bolt B, and, we prefer the use of the said
swivil slur-bolt B as aforedescribed
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
A slur-cock and bolt having a lateral motion from a fixed centre for the purpose
and in the manner as herein set forth and illustrated in the accompanying Drawings.
