Improvements in Appliances for Edge Setting Machines used in the
Manufacture of Boots and Shoes.
I, WILLIAM BRIDGEWATER of No. 25 East Bond Street Leicester in the
County of Leicester Engineer and Machinist do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in appliances for edge setting machines
used in the manufacture of boots and shoes to burnish the fore part edges or may
be waist of a boot or shoe.
By the edge setting tools now used, and by the means such tools are operated a
great strain is put upon the muscles of the arms of the operator in holding the
boot or shoe to the tool.
My invention is for the purpose of obviating this injurious effect and to practically
remove the severe vibration, so that when a boot or shoe is held to the tool, or
tools hereinafter described the operator will experience no jarring to the muscles of
the arms.
To effect this I employ two tools or irons rocking or oscillating (in holders) in
opposite directions but close together, and working side by side on parallel shafts,
spindles, or pins in the standard or pillar of the casting of the machine. By
preference such tools or irons are made circular in form, with shanks, and the usual
means for securing them in their holders, their outer face, periphery or rubbing
surface forming something like three parts of a circle, and each are provided with
lips similar to an ordinary iron. The tool holders besides being provided with a
socket for the shanks of the tools have a boss which is securely attached to a shaft,
or as before stated "parallel shafts, spindles or pins." By preference a lug may be
cast with the boss of the tool holder or upon a sleeve fitting the shaft in any
desired position, to which are attached levers mounted on the end of an horizontal
lever so that the oscillatory motion can be imparted to the tools, and to the tool
carrying shafts, the other end of the horizontal lever is made fast to a pin ontering
the casting or frame, beneath this at a suitable distance, and in or about the centre
is the driving shaft, to the outer face of which is eccentrically fitted a rod, its
upper end secured to the horizontal lever. When motion is given to the shaft by
any usual means, it causes the rising and falling of the connecting rod and levers,
and oscillates the fore part burnishing irons. The advantage of this arrangement
of giving the rubbing motion to tools arranged side by side allows the boot or shoe
to be held against the rubbing face of both.
This cannot be accomplished by the tools now employed, except they are fitted
side by side, which is the main object of my invention. I may employ the ordinary
shaped irons so that they will vibrate in opposite directions side by side and attach
them to holders attached to links as above described, and attached to the eccentric
on top of the machine on end of revolving shaft if desired. And to lessen the
labour a waist tool of the ordinary kind may be put in line with the other tools,
fixed in a bell crank holder the upper end carrying a connecting rod secured
eccentrically to the outer face of a toothed wheel gearing with a pinion secured to
the driving shaft before mentioned.
If the tool carrying shafts are carried right through the machine tools can be
mounted on both ends, and operated either from the one end or both.
The said edge setting tools are heated in the usual way. It will be obvious that
when two tools require to be oscillated in order to perform the rubbing or burnishing
operation that there are other means than those described which can be adopted

page_text: without departing from the spirit of my invention, of having two irons of the
necessary shape oscillating in opposite directions.

Improvements in Appliances for Edge Setting Machines used in the
Manufacture of Boots and Shoes.
I WILLIAM BRIDGEWATER of No. 25 East Bond Street, Leicester in the
County of Leicester Engineer and Machinist 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 :-
4
This invention relates to the construction of machines used for the setting or
burnishing the edges of boots & shoes whereby the injurious effect of the
vibration on the muscles of the operator is obviated.
To effect this I use two parallel shafts carrying irons at one or both ends and
oscillating in opposite directions one iron counteracting the vibration of the other
and running close together thus enabling the operator to press the boot or shoe
edge on the two irons at the same time, when no vibration whatever is felt by the
operator.
To effect the oscillation of the two shafts I employ two connecting pieces CC
attached to a lever D Fig. 5 which works on a fixed pin E and motion is given to
the lever D Fig. 5 by a connecting piece and eccentric F on driving shaft of
machine or other suitable means. Fig. 6 shews how the connecting pieces C C are
attached to lever D. Fig. 5 and also to sleeve G Fig. 7 by which they are
attached to the shafts.
Fig. 1 is a plan shewing the ends of the two parallel shafts with holders, and
tools or setting irons B. B fixed.
Fig. 2 is a side view of same shewing spring S to hold tool in place and allow of
free movement.
Fig. 4 is another side view with tool holder set at a slight angle.
Fig. 3 is a front view showing tools which by preference are made round and the
setting edge concentric with shaft and having two or more holes in setting irons
can when one part is worn be moved round on pin to another part and so on all
round. But irons may he used of any shape suitable for the work.
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
The use of two parallel shafts with suitable holders and tools attached and
oscillating in opposite directions and the two irons working on the boot or shoe
edge at the same time to destroy or obviate that vibration so injurious to the
operator.
