Improvements in Sole Trimming Machines.
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 :-
One of the objects of my invention is to produce a machine that will trim or
shape from what is known as blocked stock a sole or tap to any predetermined size
from a given pattern. Another object of my invention is to clamp the stock and
pattern together and arrange them in close relation with a pattern guide supported
in juxtaposition to the cutter thereby preventing variation of the sole from the
pattern, due to lateral strain or lost motion. Another object of my invention is to
provide a revolvable clamp and pattern mounted upon a shaft which is turned and
presented to the cutter by the operator, who varies the feed as the need of the stock
requires.
Another object of my invention is to mount the guide on a shifting slide so it can
be adjusted to the different sizes required by means of an adjusting screw and a
lever can be made use of when the amount of material is great enough to require
two cuts.
The various features of my invention are fully set forth in the description of the
accompanying drawings making a part of this Specification, in which-
Fig. 1 is a side elevation of my improved sole trimming or shaping machine.
Fig. 2 is a front elevation of the main fran.e and cutter.
Fig. 3 is a front elevation of the jack frame.
Fig. 4 is an enlarged top plan view, partly in section, of the cutter head and
clamping device.
Fig. 5 is an enlarged sectional elevation of the cutter head and guide.
Fig. 6 is a plan view of the pattern and spacing plate.
Fig. 7 is a section on line, Fig. 4.
Fig. 8 is a sectional detail view of the fence.
1 represents the bed plate of the machine. 2 the main frame mounted thereon.
3 represents a blower.
4 a dust tube. 5 represents the main driving shaft; 6 the
main driving pulley. This main driving pulley transmits power to pulleys 7 on
the cutter shaft 8. 9 represents a second pulley mounted on the main shaft 5 and
transmitting power by the belt 10 to the pulley on the blower shaft 11.
A repre-
sents the cutter head mounted on shaft 8. The knives or bits may be of any well
known form of construction. B represents a jack frame provided with a sleeve 12
that journals on stud shaft 13; see Fig. 2. 14 represents a driving pulley on the
main shaft 5 and 15 represents a loose pulley on the same shaft. 16 represents a
table on the bracket of which is mounted a stud shaft 17. C represents a fence
journaling on said shaft and provided with the guide 18. 19 represents a set
screw for adjusting the fence laterally on the stud 17. 20 represents a stud shaft
on which the shank 21 of the guide 18 slides. Its adjustment is regulated by the
set screw 22. 23 represents a weight attached to a chain passing over the shea ve 24,
one end of said chain 25 being secured to the weight 23, and the other end secured
to the jack frame. The weight normally draws the jack frame forward to the
cutter shaft; it is held back by means of the catch lever 26, the end of which
engages on the stud 27 on the jack frame. D represents a grooved guide which
journals in the sleeve 28. 29 represents a slide supporting said sleeve and fitting
into a guide box 30. 31 represents a set screw for adjusting the slide 29 to carry

page_text: the guide D forward and backward for adjusting it to different sizes of work
required. a, b, represent collars on the shank of the screw 31 to limit the forward
and backward movement of the slide 29. It may be desired to throw this guide
forward at times in order to reduce the extent of cut when it is required to make
two cuts instead of one, in reducing the stock. This is accomplished by moving the
shipping lever 33 so as to spring the catch 34 in engagement with the lug 35 and
thus hold the guide in its most advanced position. When the shipping lever is
moved backward the slide 29 is free to move backward. E E¹ represent clamping
heads. The clamp E is mounted upon the stud shaft F and the clamp E' is
mounted upon the gudgeon H of screw shaft G. The shaft G is screw threaded
through a split box I supported upon the fork J of the jack frame B.
K repre-
sents a sleeve supported on the fork L. This sleeve is screw threaded through the
boxing M, so that said sleeve may be adjusted longitudinally. N represents a hand
wheel secured to shaft F. O represents a handle secured to the rim of the wheel
and may be operated to turn the said shaft and revolve the clamp heads E E¹.
R represents a spacing plate provided with holes r, s, to pass over dowel pins
projecting from the clamping head E. P represents a pattern provided with
similar holes and placed between the spacing plate R and the clamping head E.
S represents stock clamped by the clamping heads E E¹. This construction
enables the clamping heads E E' to be used for various sizes of work; but the
clamping heads may be changed if desired, as they are readily detachable from
their supporting gudgeons. The clamping heads are driven by the hand wheel N
which is turned by the operator to present the stock to the action of the cutter.
Important advantages are obtained by this means, as the operator can turn the
clamping heads fast or slow, presenting the stock to the cutter no faster than it
will reduce it. Thus, if stock for the soles of a child's shoe is being reduced,
there is much less stock to be cut away and it can be revolved faster; but if
a large size, say the sole of a man's shoe, is to be reduced, there is much more stock
to be reduced and it must travel a louger distance during the revolution and much
more stock is taken off by the cutter, and a slower motion is required to avoid over
feeding. Another important advantage is obtained by arranging and clamping the
pattern close up to the stock to be reduced and the guide close to the cutter head,
and having the pattern and clamp supported on one and the same shaft and close
together; as an accurate feed of successive charges of stock may be obtained and
they are trimmed to the exact size of the pattern P which travels in the groove of
the guide D, the guide being close to the cutter head and the stock close to the
pattern. In Fig. 5 I have shown the guide D recessed out so as to span the screw
head t which clamps the cutters on the shaft 8. In order that the guide D may be
readily moved out of the way to take off the cutter head, I mount the guide box 30
on the shaft 36; where it is held in position by the clamping box 37; and
38 represents a clamping screw which is loosened to allow the said guide box to
be turned up or down, removing the guide out of the path of the cutter head. In
order to set the screw shaft G in a fixed position it passes through the split box I
where it is secured in position by set screw 39, so that said shaft G may be turned
to clamp the heads E E, and then set by the screw 39 to hold it in a fixed position.
The clamping head E forms the base on which the pattern P rests, and it must be
adjusted exactly to the groove in guide D; this adjustment is secured by turning
the sleeve K in box M so as to move the clamping head E and the pattern laterally
to secure the alignment. The spacing plate R keeps the pattern P a sufficient
distance away from the cutter to prevent the pattern from interfering with the
action of the cutter and allowing the inner edge of the stock to be completely
trimmed down.
Having now particularly described and ascertained the nature of the said 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 :-
