WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN AND RELATING TO RING
HOLDERS FOR SPINNING FRAMES," A communication from abroad by George
Draper Edmands, of Milford, Massachusetts, United States of America, Machinist.
This Invention relates to the construction of ring holders, and the method of
attaching them to the ring rails of spinning frames, and it consists partly in the use
of a ring holder provided with a circular opening and suitable seat to receive the
ring; also on providing the holder with an exterior projection upon one side,
through the centre of which is cut a narrow slit to render the said holder capable of
being sprung to slightly reduce the interior diameter thereof, and cause it to gripe
the ring, and hold it firmly therein; also in providing the holder with a slotted
bolt hole, forming an enlargement of the said slit to receive a clamping bolt for
securing the said holder to the rail, the outer portions of the upper side of the
extension contiguous to the said bolt hole and slit being inclined in opposite direc-.
tions, as herein-after more fully described.
It further consists in the use in combination with a ring holder, constructed as
above described, of a clamping bolt provided with a suitable screw thread and nut
at one end, and an oblong head at the other end, the under or bearing side of which
is under cut upon two opposite sides, or inclined downward from the body of the
bolt to the outer end or edge of the head. When placed in position to secure the

page_text: holder in place on the ring rail the inclined under surfaces of the bolt head will
rest upon and fit the inclined upper surfaces on the holder, and as the said bolt is
drawn downward, to bind the holder to the rail by screwing up the nut upon its
lower end, the said inclined surfaces will act to draw the two parts of the holder
towards each other, tending to close the slit, and cause the holder to gripe the ring,
and hold it firmly therein.
In the accompanying Drawing,-
Figure 1 is a plan of my improved holder applied to a ring rail, and holding the
ring.
Figure 2 is a vertical longitudinal section on the line x, x, Figure 1.
Figure 3 is a plan of the holder detached.
Figure 4 is a front elevation of the same;, and Figure 5. is a vertical section on
the line y, y, Figure, 3.,
A is the ring rail; Bthic clamping bolt; C, the ring; and.D, the ring holder.
The ring C.may be of any ordinary construction; the ring holder D consists of a..
metal plate; having through it the circular hole a, the upper portion of which is
counterbored to form the ledge or rest b, whereon rests the lower side of the ring C
when placed in position.
►
The exterior outline of the said holder is substantially as shown in Figure 3,
being cut on a line concentric with the periphery of the hole a for about three-
fourths of its circumference, while the other fourth is extended to form a foot or
bearing to rest upon the rail, as shown in Figure 1. Through the centre of this
extension is made a slotted or oblong bolt hole c, and extending from opposite sides
thereof radial to the hole a is cut the slit d, dividing the enlarged side of the holder!
into two prongs e and f, the outer portions of the upper sides of which are bevelled
or inclined in opposite directions, as shown in Figures 2 and 4.
The bolt B has cut upon one end a screw thread, to which is fitted a nut g, and
it has formed upon its other end an oblong head h, the under sides of the two
opposite portions-of-which are inclined-in-opposite.directions, corresponding to the
bevels on the holders before described.
-
The operation of my improved holder is as follows:-The ring C is placed in
position in the holder, resting upon the ledge b, the said ring filling tightly the
counterbore. The holder is then placed in position upon the rail, and the bolt B is
passed through the slotted hole c, and through the hole in the rail A ; the nut g is
placed on the said bolt, and turned up against the under side of the rail, drawing;
the bolt downward with the inclined surfaces of the under side of its head resting
upon the inclined upper surfaces of the prongs e and f of the holder, thereby drawing
the prongs toward each other, and causing the holder to gripe the ring, and hold it.
firmly in position therein, and at the same time clamping the holder firmly upon
the rail in any desired position.
By this Invention the ring is rendered easily adjustable to the desired position,
as the holder may be turned about the clamping bolt B, or may be moved in a
direction radial to the axis of the ring a limited distance, thereby permitting all:
needed adjustment by the simple slacking and tightening of a single nut.
Having thus fully described the said Invention, as communicated to me by my.
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,--
First. The ring holder provided with a circular seat or rest for the ring, the
prongs having their upper surfaces inclined in opposite directions, the slotted bolt
hole, and the dividing or separating slit all arranged relatively to each other, as above
described.
:
Second. The holder divided on one side by the slit, and provided with a slotted
bolt hole and bevelled prongs in combination with a ring rail, and the bolt provided
with the nut and hook-shaped head, all arranged and adapted to operate as and for
the purposes described.
!
Third. A ring holder cut open upon one side, and adapted to be sprung to gripe
the ring, and provided with one or more inclined or bevelled surfaces in combina-
2

page_text: tion with a single clamping bolt adapted to clamp the said holder to the rail, and at
the same time, by acting upon the said inclined surfaces, cause the holder to gripe
the ring, and hold it firmly in position, as above described.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Tenth day of September, in the year of our Lord One
thousand eight hundred and seventy-eight.
