Improvements in Turning and Beading Machines for use in the
Manufacture of Boots and Shoes.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, 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;-
-
The object of this invention is to simplify the driving apparatus of shoe upper
turning and beader machines, and make the parts more durable.
Another object of the invention is to provide means for controlling the move-
ment of the turning iron and to adjust the driving mechanism for the same to
fixed positions, or to control the same by treadle movement, as desired.
The various features of the invention are more fully set forth in the description
of the accompanying drawings making a part of this specification in which:
Fig. 1, is a front elevation of the improvement.
Fig. 2, is a longitudinal and vertical section drawn to an enlarged scale showing
the driving mechanism in elevation.
Fig. 3, is a section on line x, x, Fig. 2.
Fig. 4, is a section on line y, y, Fig. 2.
A represents the base on which the shell frame B rests. C represents the
stationary jaw, D the movable jaw of the beader. E represents the hollow stan-
dard in which the turning iron reciprocates. F represents the main shaft and
G the sleeve in which the same journals.
The driving mechanism of the improvement is constructed as follows: a repre-
sents a crank or wrist pin attached to shaft F. d represents a connecting rod
journalled on crank pin a and to the ear e of the yielding bar, f which is loosely
hinged to the movable jaw D. b represents an extension of the connecting rod d
In order to cushion the movement of said
carrying a secondary wrist pin c.
jaw which is oscillated on its pivot D₁ by connecting rod d, the following mechan-
isms are provided: h represents a coil spring interposed between arm f and the
outer end of the jaw D.
i represents a rubber spring between the horizontal portion of jaw D and
washer I, and g, g₁ represent the tightening bolt and nut respectively.
This said spring & cushions the downward movement of arm f, and the outward
movement of jaw D, while spring cushions the stroke of said jaw D against
the material held between it and the stationary jaw C. j represents a nut for
regulating the tension of coil spring h. Thus a noiseless movement of jaw D
and its operating mechanism is obtained; as well as cushioning its movement
at each end of the stroke. The turning iron is driven in unison with the heading
jaw by the following mechanism: to the supplemental or secondary wrist pin
is pivoted a link k, the other end of which is pivoted to the rock arm / which

page_text: oscillates on the centre . H represents the turning iron reciprocating vertically
in guides of the standard E, the longer end of which is pivoted upon the center m
of the rock arm l. In order to regulate the protuberance of the turning iron H
beyond the guides n between which it reciprocates, the rock arm is pivoted in
the following manner: K represents an oscillating arm loosely hinged at one end
to the frame of the machine by the centre bolt o, which is connected to the head O
by a pivot bolt o'. The end of said arm is made convex and engages in a concave
seat formed in the frame, and acts as the center on which said arm K rocks, the
pivot bolt o serving to hold said arm firmly to its seat.
In order to take up lost motion and to prevent rattling and jarring a spring
washer is provided and interposed between the set nut q and the frame. A
noiseless movement of said arm K is thus secured. Rock arm is connected
to this arm by means of a link pivoted thereto as shown in Figs. 2 and 3.
Arm K is provided with a shaft L which projects outward through the segmental
slot M in the side of the base frame. This shaft journals in the sleeve P and
in the hub P formed integral with the arm K. R represents a set nut tapping
on said shaft L. When said nut R is slackened the shaft L is free to move up
and down in slot M. When moved downward it depresses the arm K and lowers
the journal of the turning iron H by lowering the centre on which rock arm
is journalled.
The link turning on its center accommodates itself to the new position. By
means of the shaft L and set nut R the position of arm K can be secured at any
desired fixed point. But in case it is desired to have the movement of the turning
iron under the control of a treadle so that the operator can cause the turning
iron to protrude more or less, at will, the set nut is slackened and the treadle S
applied by connecting rod S¹ to the ear s of the sleeve P.
By means of the combination of wrist pin c with the crank pin a the driving
mechanism is simplified and operates the turning iron and beader jaws with
much less number of parts, and less friction and more positively than in any
former devices. The operator is also enabled to control the stroke of the turning
iron either by fixed adjustment or by the treadle movement, as desired. This
method of construction is much superior to all others in point of durability, which
is the most important consideration in machines of this class, on account of the
high rate of speed at which they are driven.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is: -
1. In a shoe turning and beading machine, in combination with the oscillating
beader jaw, a plate loosely hinged to the arm thereof, driving mechanism, a rod
connecting said plate with the driving mechanism, and springs interposed between
the working part of said plate and jaw to cushion the movement of the latter,
substantially as described.
2. In a shoe turning and beading machine, mechanism for reciprocating the
turning iron comprising a vertically adjustable movable arm, a rock-arm centrally
mounted thereon and having hinge connection with the turning iron, driving
mechanism, and crank and link mechanism connecting the rock arm and driving
mechanism, substantially as described.
3. In a shoe turning and beading machine the combination of the oscillating
arm K pivoted at one end to the frame of the machine and the link r connected
to the rocking driving arm 7, to which the turning iron is hinged, and means
for locking said oscillating arm in various positions, substantially as described.
4. In a shoe turning and beading machine the combination of a stationary
and an oscillating beader jaw, driving mechanism connected to the oscillating
jaw, lever mechanism connecting said driving mechanism to the turning iron,
said lever mechanism being mounted upon a vertically adjustable arm, whereby
the stroke of the turning iron is controlled, substantially as described.

page_text: 5. In a shoe turning and beading machine the combination with the main
shaft, of a connecting rod pivoted thereto, and to a yielding arm for driving the
oscillating beader jaw, a rock arm connected at one end by means of a link to the
driving mechanism and at the other end to the turning iron, said rock arm
being pivoted at a point between its ends to a vertically adjustable arm movably
secured to the frame of the machine, substantially as described.
