Improvements in Hosiery Frames.
I, FRIEDRICH MAX HILSCHER, of Chemnitz Königreich Sachsen, in the
German Empire, Manufacturer, 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:-
The speed at which flat hosiery frames run is very moderate owing to a number
of working parts having too many movements imparted during the formation of
the meshes and the fashioning, which extends the time for forming the rows.
The object of this invention is to obviate the loss of time caused by the said
movements.
In frames with movable needle-bars, for instance in "Cotton's" system, I employ
a movable knocking-over comb a, Fig. 1, of annexed drawing which is moved
backwards and forwards by levers a¹ employed either inside the row of needles,
as shown in Fig. 1, or outside the same, as shown in Fig. 14. This knocking-over
comb has a throat at its end 1 & 2, as is the case in some of the frames already
in use, but in which the said knocking-over comb remains stationary.
According to my method of working, this knocking-over comb remains only
stationary during the drawing of the loops and moves during the formation of
rows and also during the fashioning, so as to obviate the time wasted by the
movements of the other working parts as will be readily understood from the
following:
:-
"
When commencing a row of meshes the working parts are positioned relatively
to each other, as shown in Fig. 1. A fresh row of loops b, as shown in dotted
lines, having been formed by means of the sinkers c through the drawing of the
loops, in the system heretofore in use where the knocking-over comb is stationary,
Figs. 2-5, the needles n must press at first against the edge of the presser d,
Fig. 2, and having fallen until the work w is positioned on the needle hook, the
needle must recede from d (Fig. 3) so that it may fall for " knocking-over
(Fig. 4), then move again to the right (Fig. 5), below the end part 1, along the
inclined edge 2 of the knocking-over comb and rise again into position for closing
up. The needles in the meantime after pressing (Fig. 2) have moved to the left
and after knocking-over (Fig. 4) to the right which double deviation from its
downward movement results in a great loss of time when knocking-over and before
the closing up.
According to my method of working, the needles n move also from the position
shown in Fig. 1 against the edge of the presser d, Fig. 6; but the knocking-over
comb a has also receded with it in the same direction and the needles at once fall
for knocking-over the old meshes w, Fig. 7. The knocking over comb then also
advances at once, see Fig. 8, so that its inclined edge 2 assists the knocking-over
as it moves the meshes w with certainty from the needles n, the latter rising into
position for closing up (Fig. 1). Therefore in this case the needles fall and rise
at an incline and have no lateral movement whatever.
In the existing method of working, the sinkers after having receded on pressing
must also advance again during the rise of the needles (Fig. 5) in order to hold
the thread e at the border in such a manner forward and outward, (Fig. 5 dotted
lines), that the thread, when the needles have arrived will be placed around the
border needle as shown in Fig. 9. Should the same not occur, the border needle
generally rises in advance of the thread and the latter does not lay itself on the

page_text: said needle (Fig. 10) during the drawing of the loops and the work will be pushed
off the same.
The proper laying of the thread when the sinkers are employed according to the
existing method, entails a loss of time not owing to their movements, but because
they have to hold the thread until the needles have been raised, after which
they have to recede again completely before the second drawing of loops can
commence.
The thread guide, which is required to be in advance of the sinkers and the
drawing of the loops must therefore wait until the sinkers are completely drawn
back.
According to my method of working, the work is not only held downward by
the end part 1 of the knocking-over comb but also forward by the throat and the
thread in such a manner that the needles at the border behind and inside the thread
can rise and lay the same around the border needle, as shown in Figs. 9 & 11.
The sinkers are thus not necessary for forming the border and perform therefore
only the movements for the drawing and the division of the loops, after which they
recede at once to their normal position Fig. 1; the thread guide is therefore
free to move whilst the needle is still rising and at the moment when the needle has
arrived in its norinal position again, the first sinker has again drawn the thread, as
shown in dotted lines in Fig. 1. The whole of the time taken up in waiting as
herein before described during the closing up and laying the thread, the advance of
the thread guide and the drawing of the loops is thus saved by the timely movement
of the knocking-over comb.
In some instances previously it has also been necessary that the top mesh should
also move forwards and backwards with the frame needles and not only up and down,
as shown in Fig. 12, in order that the same will come in front of the hooks 2 and
may displace themselves when they are raised; afterwards when falling they must
recede again in order that the mesh w will come underneath the end part 1, and
can be transferred again to the frame needles. This forward and backward
movement is also dispensed with in my method of working as the knocking-over
comb is receding during the uncovering of the meshes, Fig. 13, the covers frise,
advance, fall again and the knocking-over comb advances again to transfer the
meshes to the frame needles.
The saving of time attained in dispensing with the said movements when
producing ordinary work is so considerable that the frame can be run fifty per cent.
quicker without increasing the velocity at which the loops are drawn, the frame
working thus just as accurate and even steadier and at the same time producing
fifty per cent. more than heretofore has been the case.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim, is-
In a hosiery frame of the class hereinbefore specified, actuating the knocking-
over comb formed with a throat during the knocking-over, the closing up and the
fashioning operation in such a manner that the frame needles during the said
operations will move more up and down (not more forward and backward as
hitherto) and the thread on the border of the work is laid around the border
needles by the knocking over comb (not by the sinkers) for the purpose of saving
time during the knocking-over, the laying of the thread by the thread guide and
the fashioning operation, all substantially as set forth.
