Improvements in Top-roll Saddles and Weight-stirrups for
Spinning Machines.
I, EZRA DIXON, of No. 49 Constitution Street, Bristol, in the County of Bristol.
State of Rhode Island, United States of America, 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 :-
This invention has reference to improvements in the construction of top-roll
saddles and the opening in the weight-links.
The object of the invention is to so construct the top-roll saddle and the opening
in the weight-link that, while the two parts may be readily secured together, they
are not liable to accidentally separate when the weight-link and saddle are removed
from the top-roll.
The invention consists in the peculiar and novel construction of the top-roll
saddle and the hole in the weight-link, as will be more fully set forth hereinafter.
Top-roll saddles, as usually constructed, have an enlarged head provided with
a transverse concavity adapted to rest on the journal of the front roll of
spinning-machines while the rest of the top-roll saddle is of smaller cross-section
and rests on the rear saddle. The weight-link rides on the top-roll saddle bebind
the enlarged head and hangs between the front or delivery roll and the drawing-roll,.
as is shown in Figure 2 of the drawings.
In carrying out my invention I provide the top-roll saddle, at a point in the
rear of the place where the weight-link is placed when the top-roll saddle is in use,
with a pin or projection, and provide the weight-link with an opening narrower.
than the head or front part of the saddle and wide enough to pass over the rear
part of the saddle but not over the pin or projection for the passage of which I
cut a way or notch on one side of the opening in the weight-link, so that the
weight-link can be passed over the saddle when the pin or projection registers
with the way to secure the saddle and link together, but prevents the accidental.
separation of the link from the saddle.
In the preferred form I so locate the pin or projection on the saddle and the
way or notch in the weight-link that they will not register when they are in
the normal position and the saddle can not be removed without being partially
turned.
Figure 1 represents a view of one form of the top-roll saddle and its weight-
stirrup when removed from the machine.
Figure 2 represents a vertical sectional view of the same showing their relations
to the top-rolls of a spinning-machine.
Figure 3 represents a modified form of the saddle and its weight-stirrup.
Figures 4, 5, 6, 7 and 8 represent modified constructions of the weight-
stirrup to adapt it for use on various shapes and locations of the engaging
devices.
Similar numerals of reference designate corresponding parts throughout.
As it is often necessary to remove the top-roll saddles with their weight-
stirrups from spinning-machines and to again replace. them in position, it is
desirable to so construct them that they will not accidentally become separated
while allowing of their ready separation, when required, by adjusting their relative
positions.

page_text: That portion of the top-roll saddle to which the weight-stirrup is secured,
sometimes called the upper member of the saddle, has an enlarged head 10 at its
forward end which is furnished on its under surface with a transverse concavity 11
to bear on the front roll 12,-extending from this head is the shank 13 which is
supported by the lower saddle 14 resting on the middle and back rolls 15 and 16.
When the top saddle is removed from the machine, the weight-stirrup 17 is liable
to slip along this shank and to become separated therefrom, to avoid this I provide
the top saddle with a stop or engaging device 18 or 19 and provide the opening 20
in the upper end of the stirrup or weight-link 17 with one or more ways or
notches 21, and in the preferred form I place the pin, stop, or engaging device,
on the saddle and the notch or way in the stirrup so that the saddle must be
turned from the normal position which it occupies when in use before the pin
or projection on the saddle will register with the way or notch in the stirrup.
The opening 20 in the stirrup may be of such dimensions that giving the
saddle a quarter turn the head 10 may be drawn through the opening and two or
more notches 21 may be made in the sides of the opening 20.
I do not wish to confine myself to the exact construction shown of the pins or
stops or the ways or notches, nor do I wish to confine myself to the relative
size of the opening 20 and the head 10.
Two pins or engaging devices 18 and 19 may be used on the same saddle and]
they may be formed so that they can only be passed each through a specific
notch, and by locating these notches on opposite sides of the opening 20 both will
have to register with their specific notches before the saddle can be separated
from the stirrup.
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 combination with a top-roll saddle having an outwardly-extending pro-
jection, of a stirrup provided with an opening for the insertion of the saddle and
a notch for the passage of the projection; the whole adapted to secure the
saddle in the stirrup and hold the same against accidental disconnection, as
described.
2. The combination with a top-roll saddle provided with an outward-extending
projection, of a weight-stirrup having an opening through which the saddle may
be readily passed and a notch, forming an extension of the opening in the
stirrup, of a shape closely registering with the outwardly-extending projection
on the saddle and located so that the saddle must be turned in the stirrup from
its normal position until the projection registers with the notch, whereby
accidental separation of the saddle and stirrup during handling is prevented, as
described.
3. The combination with a top-roll saddle, of the stop 18 and a weight-stirrup
provided with the opening 20 and notch 21; the whole constructed to hold the
saddle in the stirrup against accidental separation, as described.
