COMPLETE SPECIFICATION.
Automatic Feed Machine or Apparatus for Attaching Top Pieces to
Heels of Boots and Shoes with Ordinary Rivets or Fasteners,
or for Analogous Purposes.
I, FREDERICK THOMAS ADAMS of 96 Richmond Road, Derby, 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 :-
My invention relates to the construction of an automatic feed machine or apparatus
for attaching top pieces to heels of boots and shoes by means of rivets, sprigs, or their
equivalents and which machine can be used for similar purposes to which it may be
applicable.
•
Referring to the accompanying Drawings and to the figures and letters of reference
marked thereon Figure 1 is a half front elevation on the left side and half vertical
section on the right hand side of my machine or apparatus.
Figure 2 is a plan of the table or guide-plate & shewing the arrangement of the
cams H (hereinafter referred to) and the guide or frame G for holding boot heel G*
in central position, other parts not essential to this view being absent.
Figure 3 is an elevation of the table or guide-plate G, slide E, and moveable block (),
seen from the opposite side to that shown in Figure 1.
Figure 4 is a plan of the rivet box or hopper Q hereinafter referred to with part of
the revolving plate Q', also hereinafter referred to, broken away to exhibit parts.
Figure 5 is a vertical section of the rivet box or hopper Q on the line a a Figure 4.
Figure 6 is a side elevation of one of the cams H mounted on the table or guide-
plate G.
I provide a standard A the upper part of which A' forms a sleeve
table G, on the lower part of the sleeve G¹ of table G is fixed the bow
of boss G³. On the upper part of said sleeve I mount a radial arm B
at its upper end the movable block C by means of the slide E.
to carry the
G2 by means
which carries
The table or guide plate G is of similar shape in plan or carries a plate of the
contour of the boot heel G to be treated; it also carries a frame or guide Go to keep
the boot heel G* in a central position while being operated upon, and is provided with
holes (see Figure 2) round its outer edge into which I insert or fasten cams H (see
same Figure) wherever rivets, sprigs, or like fasteners are to be inserted. Said cams
are advantageously of the form shown in Figure 6 on edge. I mount a roller I on
the block C which bears on the outer edge or periphery of the table or guide-plate G.
A spring contained in or carried by the boss F sets up closely this roller I against the
outer periphery of the table or guide plate G.
Connected with (or carried by) the said moveable block C is a rack J and pinion K
the said rack being operated by a bolt L riding up and down the surfaces of the
cams H on the table or guide plate G.
The moveable block C carries an arm M having a metal (or other suitable) tube or
guide N (or equivalent arrangement) through which works a punch operated by
means of the said rack J and pinion K through the operation of the lever P.
Above and on the moveable block C fixed to it by an arm I mount a rivet box or
hopper Qinside of which is a revolving plate Q', see Figures 4 and 5, having
recesses of sufficient number in its outer edge for the purpose of catching the sprigs
or fasteners Q³ placed in the hopper as the plate Q¹ revolves.
The rivet box or hopper Q is conveniently carried at such an angle (and the degree
of obliquity may be adjustable) as will maintain the sprigs or fasteners in the best
position for their being picked up by the revolving plate Q. The upper part of this
plate Q' is shown in Figure 4 as broken away so as to exhibit the parts below it.

page_text: R is a slot or slit left or formed in the base plate of the rivet box or hopper Q the
said slot or slit being of sufficient width to pass the shanks of the sprigs or fasteners
but not large enough to pass their heads.
At Rthe slot or slit widens out so as to allow the head of the sprig to pass.
It
will therefore be seen that as soon as one of the recesses, containing a sprig comes over
the slot or slit R the point of the sprig falls through the slot or slit whether it arrive
point or head first the head being caught by the slot or slit and so left projecting
upwards sufficiently to permit the end of the recess Q2 to advance the sprig (as the
plate Q revolves) until it comes to the widened part R' when the sprig drops point
downwards through the small tube S (this tube is partly broken away on Figure 1 to
shew parts behind) to the larger metal tube N to which it is jointed at N. It is
however intercepted before reaching this tube by a valve T operated by the lever T
pivotted at T2 to a short bracket carried by the arm M. The upper end of the lever T¹
carries a pin with a ratchet wheel T³ engaging with a tooth U on the punch rod O¹.
To the pin O2 connecting the punch rod 0₁ and lever PI pivot a small block to
which is attached a catgut V passing over a pulley W, (said pulley being mounted
on a small bracket fixed to the arm (¹) and round pulley W₁ in the side of which it
may be fixed, or I may connect it with any other suitable gearing.
The pulley W₁ carried on the shank of ratchet wheel W2 revolves with the
spindle W3 which carries the revolving plate or disc Q¹. On the pulley W¹ is a
catch X which engages with one of the teeth of ratchet wheel W2 on the downward
stroke of the punching apparatus causing the disc or plate Q1 to revolve.
On the backward stroke the pulley W₁ revolves freely without engaging the
ratchet wheel W2 thus preventing backward motion of the revolving plate Q¹.
Secured to the top of the bow G is a rod Z the lower end of which acts as a foot
for holding the boot beel G' in its place while being operated upon. I provide a
treadle Z at lower part of standard A and connect it to the bow G2 of the machine by
⚫ means a rod Z2 to raise the bow and with it the upper part of machine while a
heel G* is being placed in position when treadle Z is released the whole of the weight
of the upper part of the machine comes on to the boot heel G thus forcing down the
plate Y and with it the spring "f" and rod" g" which may be cranked at g¹ to
actuate the lever nut h which causes the rod "i" to move forward (by means of the
right and left handed threads on the rods "i" and "s" respectively). This rod i is
connected to collar j by a taper pin k said pin working in a slot l'thus gearing the
friction pulleys m and n together and so communicating motion to the spindle o upon
which is mounted a worm (not seen) in contact with a worm wheel p which is bolted
to the radial arm B.
When the radial arm B gets to the end of its stroke it comes in contact with a lever
on spindle q operating the cam r bringing its smaller diameter against the rod s so
allowing the spring t to force the friction pulleys m. n out of gear. In place of a
spring t I may use any mechanical equivalent if desired.
The arm B being caused to revolve by hand or suitable gearing as already described
and illustrated the bolt L comes in contact with the front edge of a cam H slightly
-raising the rack J and so giving the lever P sufficient downward motion to open the
valve T (by means of the tooth U on punch rod 0¹ engaging with the ratchet
wheel T3) and thereby letting a sprig or fastener fall through the tube S into the
larger metal tube N.
The flat part of the cam H on which bolt L now rides is formed for the purpose of
allowing the sprig or fastener sufficient time to drop through the tube $ into the
tube N and on to the boot or shoe heel before the punch comes down.
This latter motion is effected by the bolt L riding up the steep part of the cam H
causing the rack J to actuate the lever P and with it the punch rod O' and punch O.
It will be seen that this downward motion brings with it the catgut V or other
equivalent gearing so causing the inner plate or disc Q₁ in the rivet box or hopper Q
to revolve as before explained.
When the bolt L disengages from the cam H the lever P returns to its normal position
and with it the punch rod O and there being a spring (not shown) underneath the

page_text: pulley W₁ or a mechanical equivalent for the spring the catgut V or connection before
referred to is immediately drawn tight and any back action of the revolving disc Q₁ is
prevented.
The ratchet wheel T3 also revolves freely on the backward movement of the punch
rod O¹ so as not to again open the valve T until the downward stroke.
This action is repeated upon the bolt L engaging with a cain H so that whenever
a sprig or fastener is desired to be inserted in a boot heel (or other goods or article
which can be worked upon by my machine) a corresponding cam is fixed into the
guide plate G.
If the pattern or shape of the, work be altered the shape of the said table or guide
plate will of course be adapted to suit the work.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a machine or apparatus for attaching top pieces to the heels of boots or shoes
or for analogous purposes, the use of a table or guide plate G having its outer edge
or periphery of the same shape or contour as the boot heel or other work required to
be operated upon and carrying cams or wedges corresponding in number to the rivets
or fasteners to be inserted, and of a plate Y and rod Z with foot d for holding the
boot heel or other work in position.
2. The use of a radial arm B carrying by means of a slide E a punching and feeding
device for rivets or fasteners.
3. The use of a roller 1 set up to the outer edge or periphery of table or guide
plate G by means of a spring for guiding the punching and feeding device.
4. The use of a rivet box or hopper containing a revolving disc and feeding device
in combination with a tube or guide N and the punch or rivetting tool O working
through said tube or guide N the valve T and lever T¹ operating the whole of the
above through the medium of lever P and rack J by means of the bolt L engaging
with cams H on plate G substantially as described herein and illustrated in the
accompanying drawings.
5. The method of using the weight of the upper part of the machine for forcing into
gear the friction pulleys thereby starting the machine as soon as treadle Z is released
substantially as described and illustrated.
"
6. The method of throwing the friction pulleys out of gear by means of radial arm B
coming in contact with lever on rod "q" actuating cam bringing its smaller
diameter opposite rod "s" thus allowing spring "t or other mechanical device to
force the friction pulleys out of gear.
"
7. The construction and arrangement of a machine or apparatus for attaching top
pieces to the heels of boots and shoes or for use in analogous purposes substantially
as described and illustrated in the accompanying drawings.
