page_text: LETTERS PATENT to Claude Edmond Dailloux, Engineer of the Firm of
Dailloux & Co., 41, Rue Clignancourt, Paris, France, for the Invention of
"IMPROVEMENTS IN MACHINERY FOR TURNING BOOT & SHOE HEELS."
Sealed the 1st September 1876, and dated the 1st March 1876.
PROVISIONAL SPECIFICATION left by the said Claude Edmond Dailloux at
the Office of the Commissioners of Patents on the 1st March 1876.
CLAUDE EDMOND DAILLOUX, Engineer, of the Firm of Dailloux & Co., 41, Rue
Clignancourt, Paris, France. "IMPROVEMENTS IN MACHINERY FOR TURNING BOOT &
SHOE HEELS."
For the purpose of my Invention, having previously built up a heel to the
approximate size, I cause it to be held firmly between the extremities of two rods or
sliafts placed in an exact line one with the other, and on one of these rods or shafts
I place a pattern of the shape to be imparted to the circular part of the heel, and
I apply a relatively slow rotary motion to these shafts, so that they both turn simul-
taneously in the same direction and at the same speed; over these two conjoined
shafts I place a mechanism susceptible of being brought down on the same and
traversed longitudinally over them by means of a handle; this overhead mechanism
consists in the first place in a metallic guide or stop which is brought down on the
pattern, and in the second place in a rotating cutter which is brought down on the
heel. When the heel is set in between the two shafts and a slow rotative motion is
imparted to them the overhead machinery having been moved laterally to the left
it is brought down until the stop rests on one end of the pattern and the cutter
on the similar end of the heel, rapid rotary motion is then imparted to the cutter,
and both the stop and the cutter are traversed slowly by the lever over the entire
length of the pattern and the heel respectively. I prefer making the cutter of one
circular plate of steel the circumference of which is turned over so as to form
a half circle in profile, which half circle I cut through in different places round
the entire circumference, thereby forming so many cutting edges.

Clignancourt, Paris, France. "IMPROVEMENTS IN MACHINERY FOR TURNING BOOT
AND SHOE HEELS."
In order that my improvements be clearly understood I will proceed to
describe them in detail, conjointly with the six Figures of the accompanying
Drawing, of which Figure I is a plan of a machine embodying such improvements;
Figure 2 a front clevation; Figure 3 a lateral elevation; Figure 4 a similar
elevation in section through A, A, Figure 2; whilst Figure 5 is a front elevation,
and Figure 6 a lateral elevation in section through B, B, Figure 5, of the circular
plate cutter which I make use of in the said machine.
In these Figures 1 is the pattern made of iron or other hard and appropriate
substance, and 2 the leather heel to be trimined or turned according to the shape
of the said pattern; 3 the guide or stop made of metal or other hard appro-
priate substance, which is brought down and travelled from left to right on the
guide or pattern 1, and 4 the circular plate cutter, which is brought down simul-
taneous and traversed over the heel 2, a rapid rotary motion being imparted
to the same during this operation. The pattern 1 is fixed to the horizontal shaft 5
in any appropriate manner so that it can be rapidly. changed, and the leather
heel 2 is solidly fixed between the extremity of this shaft and the opposite
extremity of the shaft 6 by means of the screw 7 rotated by the hand wheel 8.
The stop 3 is attached to an arm projecting from a slide 9, its position being regu-
lated by means of screws or otherwise, the circular plate cutter 4 is mounted
on a shaft 10 rotating in bearings 11, 11, which project also from the slide 9. This
slide 9 is traversed with the parts and 4 over those 1 and 2 by means of a
thread 12, it travels on the extremity of a headstock 13 which pivots in bearings
14 of the frame 15 set up on the main stand 16; a handle 16* projecting from the
headstock 13 serves to bring down the stop 3 hard upon the pattern 1. Motion
is imparted to these afore-mentioned parts in the following manner from the
driving shaft 17, which receives rapid rotary motion from a driving strap passing
over the pulley 18, firstly to the pattern 1 and the heel 2 by means of a strap 19
imparting a reduced rotary motion to the lower shaft 20 by a second strap 21,
imparting a still further reduced motion to an upper shaft 21× from which two
pinions 22, 22, impart also reduced motion to the gears 23, 23, fixed respectively
to the shafts 5 and 6, secondly, to the circular cutter plate 4 by means of the
strap 24 and pullies 25 and 26; thirdly, the traversing motion is imparted to
the slide 9 carrying the stop 3 and the rotary cutter 4 by means of the pinion 27
o the driving shaft 17 gearing in the wheel 28, on the intermediate shaft 29,
the pinion 30 on the same shaft, and the gear 31 on the upper shaft 32, the
central part of this shaft is screwed at 12, and passes in tapped levers 33 and 34,
hung at 34x on a lug projecting upwards from the slide 9. The circular cutter 4,
as shewn on a larger scale at Figures 5 and 6, is made of one plate of steel with
its edge turned round inwards in the shape of a half circle over its entire circum-
ference, when in this state it is turned true in a lathe, and afterwards it is slotted
through diagonally at regular intervals so as to form so many cutting edges 35,
nine such edges have been shewn in the Drawing, they may, however, be augmented
or diminished according to circumstances, the cutter is then hardened and tem-
pered, its circumference trued afresh if required by means of a grindstone or an
emnery wheel, and the edges 35 sharpened in any appropriate manner or by any
appropriate means.

page_text: cutter is brought back entirely to the left, the machine is put in motion by
means of the driving strap on the pulley 18, and then the stop 3 is brought down
on the pattern 1 by means of the handle 16*, the cutter 4 descending to the left
out of contact with the heel 4, under these circumstances the stop and the cutter
(the latter rotating rapidly) are slowly traversed from left to right by the screw 12
the stop constantly resting on the pattern, thereby forcing the cutter to reduce
the rough shaped heel exactly to its own contaur. Although one particular pattern
can only impart one particular shape to a heel, such heels may be made larger or
smaller with the same pattern, by simply lowering or raising more or less the
guide or stop in the slide 9. When the cutter 4 has passed entirely over the
heel 2, thereby completing it, the further traversing motion of the slide 9, and its
concomitant parts is arrested in the following manner-An upright 35 on the
slide 9 pushes the arm 36 of a bell-crank lever hung on the vertical pin 37,
deviating it 'to the right, whereby the other arm 38 of this lever strikes the
upright 39 on nut lever 33, and disengages it by means of a click from the lower
half 34 whereon a spring 40 set between the two parts 33 and 34 separates so that
the screw 12 is left free to rotate without acting on the said parts 33 and 34
formning the nut.
Having thus explained the nature of my Invention as well as the best means
that I am acquainted with for carrying the same into practical operation, I
claim―
Firstly. The arrangement and construction of parts for fixing the heel to be
trimmed between two rotating shafts, one of which carrying the pattern.
Secondly. The adaptation of the peculiar construction of the circular plate cutter
to the machine.
Thirdly. The arrangement and construction of parts for lowering the stop and
the cutter on the pattern and the heel respectively and traversing the former over
the latter,
Fourthly. The means above described of imparting to the different parts of
the machine the different rotary motions as well as the traversing motion.
And Fifthly. The mechanism above described for arresting the traversing motion
of the slide when the heel has been trimmed.
In witness whereof, J, the said Claude Edmond Dailloux, have hereunto set
my hand and seal, this Thirtieth day of August, in the year of our Lord
One thousand eight hundred and seventy-six.
