Improvements in the Beat up Mechanism of Looms for Weaving.
I, EDWARD HOLLINGWORTH, of Hutchinson, Hollingworth & Company,
Limited, of Dobcross, in the County of York, l'ower Loom Makers, do hereby
declare the nature of this invention (which has been communicated to me by
Eugene Renz, of Stirling, in the County of Morris and State of New Jersey, in
the United States of America, Power Loom Maker) and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement:-
My invention relates to looms, and more particularly to the lay or beating up
mechanism, and the dwell stand intermediate the lay sword and the crank shaft
connector.
In the class of loom to which my improvements are to be applied, the dwell
stand as it is termed is rigidly attached at its lower end to the lay sword, and
pivotally attached at its upper end to the crank connector and the lay sword.
When the lay protects to stop the loom, the crank shaft does not stop imme-
diately, but pushes by means of the crank connector upon the dwell stand in an
upward direction, and the dwell stand being rigidly attached to the lay sword
at its lower end, cannot yield, and consequently the dwell stand is often broken,
and sometimes even the lay sword.
The object of my invention is to provide relief for the lower end of the dwell
stand, so that the upper end of the stand may swing or move on the pivot pin
connecting it with the lay sword when the lay protects, and thus prevent the
breaking of the dwell stand or of the lay sword.
My invention consists in certain novel features of construction of the dwell
stand, and more particularly in providing for the yielding or moving of the lower
end of the dwell stand, so that the upper end may swing or move on its pivot
connection with the lay sword when the lay protects.
Referring to the drawing:-
I have shewn in the drawing a sectional elevation of portions of a loom of well
known construction and operation with my improvements applied thereto.
In the accompanying drawing, 1 is the loom side or end, 2 is the crank shaft,
3 the crank connector, 4 the crank connector pin connecting the crank con-
nector 3 with the rear upper end of the dwell stand 5. The front upper end of
the dwell stand 5 is pivotally connected with the rear of the lay sword
pin 6. The lay sword 7 carries the lay 8, on which is the race plate 9, and the
lay foot 10 is mounted on the rock shaft 11.
by the
The protector rod stand 12 is secured to the lay S, and carries the protector
finger 13, which is adapted to engage the bunter lever 14 on the bunter stand 15.
secured to the breast beam 16, when the lay protects.
All of the above parts are of the ordinary construction and operation in the
class of looms to which my improvements may be applied.
In the ordinary construction of the dwell stand 5, the lower end 51 is made a
part of or
rigidly secured to the lay sword 7. In my improved construction the

page_text: lower end 5 of the dwell stand 5 is not rigidly secured to the lay sword, but is
connected therewith, so as to have a movement independent of the lay sword, to
allow the upper forward end of the dwell stand 5 to swing or move on its pivot
pin 6, when the lay protects.
In this instance I have yieldingly connected the lower end 51 of the dwell
stand 5 of the lay sword 7 by means of a pin 17, which extends loosely through
a hole in the lower end 5¹ of the dwell stand 5, and through a hole in the lay
sword, and is secured to the lay sword by a set screw 18.
A washer 19 is loosely mounted on the pin 17, and bears against the inner
surface of the opening in the lower end 5 of the dwell stand 5. A spiral com-
pression spring 20 encircles the pin 17 intermediate the washer 19 and the head
of the pin 17.
The spring 20 acts to hold the lower end 5¹ of the dwell stand 5 against the
lay sword 7, to move with said lay sword, but also allows the lower end 5' of the
dwell stand 5 to yield and move away from the lay sword, so that the upper front
end of the dwell stand 5 can swing or move on its pivot pin 6.
The operation of my improvements will be readily understood by those skilled
in the art.
When the lay protects, the protector finger 13 strikes the bunter lever 14,
which falls back against the stand 15 in the ordinary way.
The movement of
the bunter lever 14 acting through a mechanism of ordinary construction and
operation, not shewn, throws off the power, but the crank shaft 2 does not stop
immediately, but pushes by means of the crank connector 3 upon the dwell
stand 5 in an upward direction, which causes the upper end of said dwell stand
to swing or move on the pivot pin 6, and the lower end 5 of said dwell
stand to move away from the lay sword and compress the spring 20, thus relieving
the sword and dwell stand from the strain which might break the sword or dwell
stand.
The advantages of my improvements will be readily appreciated by those skilled
in the art.
It will be understood that I do not limit myself to the particular mechanism
shewn in the drawing for yieldingly connecting the lower end of the dwell stand
with the lay sword, as other equivalent means may be used to allow the upper end
of the dwell stand to swing or move on its pivot connection.
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:-
In a loom, the combination with the crank shaft, crank connector, and the lay
sword, of a dwell stand. with its upper end intermediate the crank connector and
lay sword, and pivotally attached thereto to form a connection between them,
and its lower end yieldingly connected with the lay sword by means of a pin and
compression spring, substantially as shewn and described.
