page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 relates to spindle steps for spinning frames; and has for its
object to provide a device of this class which shall possess superior advantages as
regards simplicity, durability and general efficiency; which shall have capacity for
receiving lubricating material in sufficient quantity for the device to run for a
long period without refilling; and which shall be so constructed as to prevent
the oil from escaping, or from ascending the spindle, which would be obviously
objectionable. With these ends in view, the invention consists in the improved
construction, arrangement and combination of parts hereinafter described.
In the accompanying drawing
Figure 1 is a perspective view of my improved spindle step, showing the same
in position upon the frame rail, ready for operation, only the lower end of the
spindle and only a portion of the frame rail being shown;
Figure 2 is a vertical sectional view of the same;
Figure 3 is a vertical sectional view of the same, showing the spindle case filled
with oil, and illustrating the position assumed by the oil when the device is in
operation;
Figure 4 is a perspective view of the flanged bearing or step for the lower end of
the spindle, detached from the case;
Figure 5 is a horizontal sectional view on the line, xx, Figure 2; and
Figure 6 is a perspective view of the interior case removed from the step box,
parts of the same having been broken away for the purpose of illustrating the
construction inore clearly.
Like letters of reference indicate corresponding parts in the different figures of
the drawing.
A designates the rail of the spinning frame, in which the step-box B is mounte
by means of its downwardly extending projection C, which enters a socket D in
the rail, where it is retained by means of a screw E inserted from the side of the
latter.

page_text: The step-box B is preferably of a cylindrical shape. The projection C is
provided with a recess extending nearly to its bottom, in which is placed the
block F, which is also recessed nearly to its bottom, forming a step or bearing H
for the lower end of the spindle M. This block F is provided with vertical
flanges G, which fit in a recess in the projection C, tightly enough to keep it from
turning with the spindle. These flanges also form channels for the oil to pass
down from the upper part of the step-box. Between cach pair of the flanges G,
directly above the bottom of the bearing, is a horizontal perforation I, through
which the oil passes from the spaces between the flanges to the step H.
The spindle case J, is a shell fitting within the step box B, and provided at the
top with a concave or cup-shaped cover L, having a flange K, and a central
perforation through which the spindle passes and which forms a bearing for the
same. This cover is also provided with two perforations N, N, through which the
oil is introduced within the case J.
In operation, the case, J and the spindle are placed in position, and the spindle
case is then filled with oil about to the level of the lower edge of the cup or
flange The oil will fill the spaces between the flanges G, and pass through the
perforations I to the bearing at the lower, end of the spindle, which is thus kept
freely supplied with oil. In operation, the oil contained in the case will, by the
centrifugal action of the spindle, be thrown or forced in an outward direction
against the walls of the case, by contact with which it is driven in an upward
direction against the cup or flange L, as shown in Figure 3 of the drawing. The
general construction is simple, and the oil-holding capacity is so great that the
device may run for a very considerable period without attention.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed as communicated to
me from my foreign Correspondent I declare that what I claim is ;-
First. In spindle steps or bearings, the combination of a step-box having a
downwardly extending projection; a cylindrical bearing block arranged in a socket
in said projection and having exterior vertical flanges fitting tightly in the latter,
and horizontal perforations arranged between the flanges and directly above the
bottom of the step or bearing; and an inner case, fitted in the step-box and
provided at its upper edge with a downwardly and inwardly extending annular
concave flange or cup provided with openings or perforations, all arranged and
operating substantially as, and for the purpose, herein set forth.
Second. The step-box B, spindle case J, cup L, block F, and spindle M, combined
and arranged to operate substantially as described.
