Improvements in Spinning Frames.
I ROBINSON WALMSLEY of Fall River, Bristol County, in the State of Massa-
chusetts one of the United States of America, Superintendent of Cotton Mill 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:-
In spinning machines as now commonly made, the guide-eyes are secured to short
sections of wire-boards, and the latter are hinged to a guide-board fixed to the
frame, and when the bobbins are to be doffed, the wire-boards are turned up and
over.
In accordance with one part of my invention, I have hinged the guide-board to the
frame, and provided mechanical devices, whereby the guide-board with all the wire-
boards connected to it may be turned up for doffing and be locked in elevation while
the bobbins are being doffed, the said devices consisting of a locking bar and a slotted
link.
In accordance with another part of my invention, the guide-board hinges are made
vertically adjustable on the frame to thus enable the guide-board to be adjusted
vertically on the frame; and so also the frame is provided with adjustable stops or
rests to support the guide-board when turned down into working position, the adjust-
ment of the said supports or rests enabling the guide-wires to be kept at the desired
distance above the tops of the spindles.
Fig. 1. in front elevation represents part of a spinning machine using a ring and
traveller with my improved guide-board and co-operating devices, the guide-board
being shown as elevated for doffing.
Fig. 2, a right-hand side elevation of the parts shown in Fig. 1, the full lines
showing the guide-board as lowered, the dotted lines showing it elevated as in Fig. 1,
and
Fig. 3 is an enlarged sectional detail of part of the frame, part of the guide-board,
its hinge, and one of the adjustable supports or rests.
The frame work A, the roller frame or head B, the roller stand C, the top
rolls a, b, c, the step-rail the steps 10, the spindles d, the bolster rail f¹, the ring
rail g, its rings 12, the bobbins e, the guide-wires m, and the wire-boards n hinged to
the guide-board, are and may be all as usual.
In accordance with my inventions, the guide-board preferably as long as the frame,
is hinged at suitable intervals to the head B by hinges 18, the parts of the hinges
joined to the head being longer than the parts of the hinges attached to the guide-
board, as best shown in Fig. 3, the longer part of each hinge being slotted, as at 19,
to enable the guideboard to be adjusted vertically with relation to the head B as
material or twist require.

The same bolts that hold the hinges of the guide-board in adjusted position, also
extend through slots in a support or rest r, slotted as shown in Fig. 3, adjustment of
the rest r with the hinge enabling the guide-board to be supported properly when in
its down-turned position after doffing.
The guide-board, at its under side, has attached to it a hand-piece s having a lug
or ears, to which is jointed at 22, the locking-device shown as a notched bar s²
adapted to engage the lower end of the slotted link t, the said link being slotted, as
best shown in Fig. 1, and having combined with it a set screw 32.
The bar has, as shown, two notches, but it may have any desired number of
notches, so that when the operator engages the hand piece s to lift the guide-board
prior to doffing the bobbins, the notched parts of the bar will engage the link t and
retain the guide-board elevated.

page_text: To lower the guide-board, the bar s² will be disengaged from the link t.
The ear s forming part of the hand piece, forms a firm support for the bar s².
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1:-The top-rail; the guide-board; and its attached wire-boards having guide-
wires; combined with the hinges connecting the guide-board and head, and slotted to
enable the same to be adjusted, as described.
2: The top-rail; the guide-board; and its attached wire-boards; combined with
the vertically adjustable hinges, and the vertically adjustable supports or rests,
substantially as described.
3: The top-rail; the guide-board hinged thereto; and its attached wire-boards;
combined with the hand-piece; and the locking-bar; and the link, to operate,
substantially as described.
4 The top-rail; the guide-board hinged thereto; and its attached wire-boards;
combined with the hand-piece; and the locking-bar; and the adjustable slotted link,
to operate, substantially as described.
Dated the 2nd day of December 1889.
