Improvements in Channel Flap Laying Machinery Employed in
Boot and Shoe Manufacture.
A communication from abroad by JOHN BENJAMIN HADAWAY, of Brockton, in
the County of Plymouth and State of Massachusetts, in the United States of
America, Inventor.
I ALFEED GEORGE BROOKES of 55 and 56 Chancery Lane in the County of
London, Chartered Patent Agent, 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 :-
It has heretofore been proposed to construct a channel flap laying machine
embodying a rotary channel flap laying tool mounted upon and actuated by a
driving shaft, and to provide for a spring controlled longitudinal movement of said
shaft, the arrangement being such that the tool has a yieldingly controlled
longitudinal movement, and a rigidly controlled motion of rotation, the tool being
commonly rigidly mounted upon its shaft to rotate therewith.
The above suggested arrangement has been found to be objectionable in that
unless great care is exercised in applying the shoe to the tool, the shoe receives
the unyielding impact of the tool as it is rotated which is apt to tear off a portion
of the channel flap or otherwise mar or injure the shoe.
The object of the present invention is to remedy the objections above noted and
generally to improve the construction and mode of operation of the machine.
To the above end the present invention consists in so arranging the channel flap
laying tool that it is yieldingly controlled in its motion of rotation and also preferably
has a yieldingly controlled longitudinal movement. The present invention further
consists of certain improvements in the form and arrangement of component parts
of the machine hereinafter more specifically set forth and claimed.
A preferred form of the present invention is illustrated in the accompanying
drawings in which :
Figure 1 is a side view of a channel flap laying machine embodying the same,
Figure 2 is a front view of channel flap laying tool showing portion of mechanism
whereby said tool is connected with its driving shaft,
Figure 3 is a sectional view taken on line a, a Fig. 2 looking in the direction of
the arrow head.
Figure 4 is a detail sectional view of portion of mechanism for securing a
yieldingly controlled longitudinal and rotary movement of the tool, and
Figure 5 is a detail view in end elevation of a portion of said mechanism.
Similar letters of reference refer to similar parts throughout the several views.
In the drawings A represents a frame or standard suitable to support the working
parts of the machine.
In the frame A, in suitable bearings B, B, is mounted the driving shaft C.
The shaft C is free to rotate in its bearings B, B, but, in the form of my
invention shown in the drawings, is held from longitudinal movement therein by
means of suitably placed collars c, c. The shaft C may be conveniently actuated
by means of the fast and loose pulleys D, D', mounted thereon.
E represents the channel flap laying tool which in itself forms no part of the
present invention, and which may be of any suitable construction.

page_text: As shown in the drawing the tool E comprises a wheel e from the rim of which
are projected a.series of radial blades e', suitably shaped for application to the shoe
and by means of which the channel flap is laid.
The tool E is mounted upon a sleeve or hub F, which is loosely mounted upon
the shaft C, so as to be movable along the shaft C and capable of rotation
independently thereof.
His a collar or sleeve fixedly secured to the shaft C, conveniently by means of
a set screw A. Upon the sleeve H are formed the inclined or wedge shaped
projections h¹, h³, which are fitted to correspondingly shaped recesses f, f, in the
hub F.
The reference letter L represents a suitably placed spring, conveniently a coiled
spring wound about the shaft C and bearing against the collar e and the hub F.
The action of spring L tends to advance the hub F toward the collar H, and to
keep the projections A¹ in engagement with the recesses f, f. Upon the hub F is
conveniently formed a preferably tubular projection which is projected along
the shaft C, inside of the spring L. Upon the collar c is conveniently formed a
similar projection c¹, which also extends along the shaft C inside the spring L
(see Fig. 4).
The projections f¹ and c¹ act as stops to limit the movement of the hub F along
the shaft C against the action of spring L.
In operating the machine of the drawings the shoe is presented to and pressed
against the tool E in the usual manner in such position that the blades e¹, el come
in contact with the sole at the proper inclination to turn over and lay the ohannel
flap.
When the pressure of the shoe is applied at or near the periphery of the tool E
the rotation of the rim of the wheel is retarded, which causes the hub F to ride
up on the projections A', and to move longitudinally along the shaft C against the
action of the spring L. The extent of the movement of the hub F depends upon
the amount of pressure applied to the tool E, the stops f¹ and c' acting to prevent
the hub F from riding over the projections ¹ in case too great pressure is
applied.
It will be noted that the above described arrangement is such that the longitudinal
and rotary movements of the tool E are both controlled by the spring L, so that
whether the shoe is applied to the periphery or on the face of the tool E, the
blades e always strike the shoe with a yielding impact, which removes any liability
of injuring or marring the sole.
Having thus described my invention and its mode of operation I desire to say
that I do not consider the same as limited to the specific construction herein shown
and described as it is evident that many variations and alterations. may be made
therein without any departure from the essential nature of my invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is :
1. In a channel flap laying machine the combination of a rotary tool, and means
for actuating said tool having provision for a yieldingly controlled rotary and
longitudinal movement of said tool, substantially as described.
2. In a channel flap laying machine the combination of a rotary tool, and a fixed
inclined projection and elastic means co-operating therewith to control the rotary
movement of the tool, substantially as described.
3. In a channel flap laying machine the combination of a rotary shaft, a tool
mounted thereon, opposed projections carried by said shaft and tool, and means for
holding said projections in contact, substantially as described.
4. In a chanuel flap laying machine the combination of a rotary shaft, a tool
loosely mounted thereon, an inclined projection carried by the shaft and yielding
means for holding said tool in contact with said projection, substantially as
described.

page_text: 5. In a channel flap laying machine the combination of a rotary shaft, a tool
loosely mounted thereon, an inclined projection carried by the shaft, an inclined
recess upon the tool, and a spring acting to keep said projection in engagement
with said recess, substantially as described.
6. In a channel flap laying machine the combination of a rotary tool, and means
for actuating said tool having provision for a yieldingly controlled rotary movement
of said tool, substantially as described.
7. In a channel flap laying machine the combination of a rotary shaft, a tool
mounted thereon, and a longitudinally yielding connection between said shaft and
tool, substantially as described.
8. In a channel flap laying machine the combination of a rotary tool, mechanism
for actuating said tool, and connections between said tool and its actuating
mechanism having provision for allowing a yielding movement of said tool in a
direction opposite to that of its rotation, substantially as described.
