Improvements in Spinning-rings and in Apparatus for Repairing
the same.
I, FRANK MERRICK MARCY, of Worcester, in the County of Worcester and State
of Massachusetts, United States of America, Manufacturer, do hereby declare the
nature of my invention for "IMPROVEMENTS IN SPINNING RINGS AND IN APPARATUS
FOR REPAIRING THE SAME" 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 an apparatus for repairing, or restoring the flanged
track of spinning rings, which have become worn through long continued use by
the friction of the traveller, so the same will be again fitted for further use in the
spinning frame.
In the following description reference is made to the figures in the accom-
panying drawings, which show an apparatus for the purpose hereinafter specified
and which embodies my invention, and in which
Figure 1 represents a side view of the apparatus with a spinning ring held therein
and in position to be acted upon by the operative parts of the apparatus.
Figure 2 is an end view of the operative parts of the apparatus, with the spinning
ring shown in central sectional view and with the supporting framework and driving
portion of the mechanism removed.
Figure 3 represents the spinning ring in central sectional view, and with the
operative portion of the apparatus in sectional view on line Y, Fig. 2.
Figure is a sectional view taken on line X, X, Figure 2.
Figure 5 is a detached view of the one of the side dies.
a
Figure 6 is a sectional view of the same on line %, Z, Figure 5, showing
transverse sectional view of the side die and a plan view of the scraping lip by which
the edge of the flanged track of the spinning ring is scraped, and
Figure 7 represents a central sectional view of a spinning ring provided with a
flanged track upon opposite edges of the ring and allowing the ring to be turned,
when one of the flanged tracks is worn, thereby bringing the other into use.
In the drawings, A denotes the supporting framework upon which the operative
portions of the apparatus is supported, and comprising the horizontal tables A'
and A, separated by posts B, B. Journaled in a box is a short shaft C carrying
the belt pulley C by which power is applied to the machine.
Upon the opposite end of the short horizontal shaft C is a bevelled pinion D,
engaging a bevelled gear D' attached to the vertical shaft E, journaled in the
bearing E and the step-bearing E". A cup-shaped socket F is formed upon the
upper end of the vertical shaft E, and provided with a set screw F1, by which
the spinning ring is held from rotation within the cup-shaped socket F. Mounted
upon the upper table A" is a post G, to the top of which is loosely hinged a lever G'
by means of the pin a, and upon the free end of the lever G is formed the head G".
The head G" is provided with a groove H, forming a way for a sliding steel bar H³;
which I term the central, or track expanding die, and which is forced downward
upon the upper surface of the flanged track by means of a screw H₁ held in the
head G¹ and bearing upon the upper end of the central die H¹.
Hinged to the upper portion of the head G" by means of the pintles b, b, are the
steel bars I, I, forming what I term the side dies. The lower ends of the side
dies I, I, are turned inwardly to form the lips J, J', which extend beneath the
flanged track of the ring and press against the waist of the ring.
Upon the inner sides of the side dies are also formed the scraping lips c, c, which in
the operation of the machine are brought against the edges of the flanged track
of the ring.

page_text: Pressure is applied to the side dies I, 1' by means of the screws K, K, held in the
swinging arms K' K', which are attached to the rocking shaft K" journaled in the
lever G, allowing the arms K' to be raised in the position indicated by the broken lines
in Fig. 1. Small pins e, e, project from the sides of the head G" to limit the downward
swinging movement of the arms K', and sustain them in the proper position to allow
the screws K, K, to be brought against the sides of the side dies I, I³, as represented
in Figures 1 and 2.
N denotes a spinning ring of which is the base, g the waist, and h, k, are the
flanges forming the track for the traveller.
The operation of the apparatus is as follows: the spinning ring is placed in the
cup-shaped socket F and fastened from rotation within the socket by the set-screw F¹¹,
causing the ring to be rotated by the rotation of the vertical spindle or shaft E.
The lever G¹ is turned upon its pivotal pin a, to bring the lower end of the central,
or track expanding dio upon the flanged track of the spinning ring as shown in the
sectional view in Figure 3. The hinged side dies I and I are then carried toward the
head G bringing the lips J, J' beneath the flanges h, h, and against the opposite sides
of the waist, the swinging arms K' are then brought from the position of the
broken lines, Figure 1, to the position in which they are represented in Figures 1
and 2, and resting upon the projecting pins e, e.
The screws K, K, are brought to press against the sides of the side dies 1, 11,
pressing the faces of the lips J, J' firmly against the sides of the waist g of the
spinning ring. Pressure is applied to the central die H, which serves to expand
the flanges h, h, upon either side and widen the track of the ring, and as the pressure
is applied to the die H¹ by the screw H", the side dies I and I are drawn upward
against the under surfaces of the flanges h, h, thereby supporting the flanges and
compressing them between the dies H and 1, I', causing them to be expanded
laterally filling the space between the scraping lips c, c.
During the operation the vertical shaft is rotated, carrying the ring N between
the dies H, I, I and the pressure upon the die H' is applied gradually so the lateral
expansion of the flanges is gradual and continuous until the desired width of the
track is obtained.
The lips c. c, serve to restrain the lateral expansion of the flanges h, h, within their
limits and they also Lave a scraping action upon the edges of the flanges h, h, by which
they aro smoothed by the removal of inequalities and also rendered concentric with the
axis of rotation of the ring.
The lever Gis pivoted loosely upon the pin a, in the post G in order to permit a
slight lateral movement of the head G₁ and its dies H¹, I, 1' to accommodate any
irregular or eccentric movement of the ring N as it is carried by the vertical
shaft E.
When the flanges h, h, have been restored to the proper width to form the track
for the traveller, the screws K, K, are loosened; the arms K, K' raised to the
position indicated by the broken lines in Figure 1, and the side dies I, I' are
withdrawn from the sides of the ring permitting the ring to be replaced and the
operation repeated.
It will be obvious that the essential features of my invention would be embodied,
substantially, in an apparatus in which the ring itself was held stationary and the
head Gand dies H, I, 11, were caused to rotate about the flanged track of the ring
neither do I confine myself to the specific means shown and described for the purpose
of applying pressure to the dies El', I, 1', the essential feature of the process and of
the mechanism to carry the same into effect being the application of pressure to the
flanged track of a spinning ring, by which the flanges are expanded laterally, and at
the same time restrained within determinate limits, and also rendered concentric with
the axis of rotation of the ring, so as to form a track for the traveller of the proper
width and with its edges concentric and smooth.
In case a double ring, or a ring having a flanged track upon its upper and lower
edges, is to be operated upon, the cup-shaped socket F is made slightly shallower
than is represented in Figure 2 of the drawings in order to allow the flanged track

page_text: to project above the top of the cup-shaped socket and the ring is held from rotation
within the socket by a series of three or more screws bearing against the lower half
of the waist g.
A double flanged ring is shown in central sectional view in Figure 7, provided
with the tracks h and i, upon its opposite edges, and having the waist g, against
which the holding screws are brought to bear, leaving sufficient space for the
insertion of the lips J, J₁ of the side dies I, l' as already described in the case of
the single track ring N.
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 1
claim is:
First. In an apparatus for repairing spinning rings, the combination of the
central track expanding die, and a pair of side dies provided with lips arranged to
bear against the sides of the waist of the spinning ring and means connected with
said dies, whereby pressure is applied to the flanged track of the spinning ring,
substantially as described.
Second. In an apparatus for repairing spinning rings, the combination of the
central track expanding die H¹, the side dies I, I provided with the lips c, c,
arranged to scrape the edges of the flanged track of the spinning ring and means
connected with said dies, whereby they are pressed against said ring, substantially as
described.
Third. In an apparatus for repairing spinning rings, the combination of the central
track expanding die H', the side dies I, I provided with lips J, J', extending beneath
the flanged track of the ring, pressure screw H", said screw and said dies being

lips J, Jare caused to exert a reciprocal pressure upon the opposite surfaces of
the flanged track of the spinning ring, substantially as described.
Fourth. In an apparatus for repairing spinning rings, the combination of a rotating
shaft E, provided with devices whereby the spinning ring is held and caused to
rotate with said shaft, dies H', and I, I' held upon and supported by a hinged
lever G, whereby said dies are brought into the path of the annular flanged track of
the spinning ring, as it is rotated, substantially as described.
Fifth. In an apparatus for repairing spinning rings, the combination of a rotating
shaft E, cup-shaped socket F carried by said rotating shaft and having its axis
coincident with the axis of said shaft, a retaining set screw F1, by which a spinning
ring is held from rotation within said cup-shaped socket, and means, substantially
as described, whreeby pressure is applied to the opposite surfaces of the flanged
track of the ring, for the purpose of laterally expanding the same and restoring
the normal width of the track, substantially as described.
