We, JUDSON LEVATOR THOMSON, Manufacturer, of Syracuse, in the County of
Onondaga and State of New York, one of the United States of America, and JOHN
HUNTER, Manufacturer, of Sterling Valley, in the County of Cayuga and State afore-
said, 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 :—
Our invention has for its object the production of a. machine for the insertion of
rivets into the soles of arctics and like overshoes in which the operation of inserting
the rivet, and clinching or heading the clinching prongs shall be automatic and con-
tinuous by simply securing the overshoe upon a riveting block and presenting the
same to the punches and operating the clinching mechanism and feeding mechanism
by the treadle; and to this end the invention consists in a riveting machine com-
prising an automatic feed for feeding the rivets to the heading mechanism,
mechanism for distributing and arranging the rivets circumferentially on the heel of
the arctic or overshoe, and a cut-off for stopping the feed automatically while the
rivets are
being clinched by the heading mechanism; Also in combining with the
automatic feeding mechanism and combined adjustable riveting block a shoe holder
Also in providing a receptacle or hopper for the feed with discharge openings, and
mechanism for forcing the rivets into feeding tubes shank foremost; Also in pro-
viding means at the discharge end or exits of the feeding tubes to guide the rivet
accurately to the work; Also in the detail construction and arrangement of the
parts, all as hereinafter more particularly described and pointed out in the claims.
In specifying our invention, reference is had to the accompanying drawings in
which like letters indicate corresponding parts in all the views.

A-represents the feed receptacle or hopper, and the same is made preferably
circular in shape, and of sufficient capacity to hold a large number of rivets. The hopper
is provided with a hole 1 for the shaft 2, and the shaft 2 carries the frame 4 from
which depend brushes 3 which oscillate on the shaft 2 as a pivot and serve to feed

page_text: the rivets to the discharge openings or passages 5. The bottom 11 of the hopper or
receptacle-A-is conical in form as best shown in Fig. 8, and the openings 5 are of
the contour in cross section shown in Fig. 11, and have an enlargement 6 at their,
lower extremity, over which we place the plate 7. The said passage or opening
comes over feed conveying tubes B-in which, in close proximity to the upper
extremity thereof as shown in Fig. 10, we place a screw 8 which serves in connection
with the plate 7 to compel the rivets to fall shank foremost into the feed conveying
tubes B.
It will be observed upon referring to Figs. 7, 8 and 10 of the drawing that the
plate 7 is placed over the enlargement 6 of the discharge openings in the hopper,
and that the rivets as they are brushed into the openings, pass under the plate into
the enlargement and thence into the feed tubes-B. If the rivets enter the openings
shank uppermost, the shank collides with the edge of the plate, and the rivet falls
either sideways or shank foremost into the feed tubes-B;-Should it fall sideways
into the feed conveying tubes, it strikes against the screw 8 which is placed near the
upper extremity of the tubes-B-for this purpose, and the contact of the rivet with
the screw 8 turns it shank foremost, and in this position it passes through the tube to
the exit. The screw 8 is beveled flatwise to a point as best shown in the sectional
view Fig. 10, and the collision of the rivet with the screw compels it to fall, in the
desired portion i.e. shank foremost, thus securing the desired result.
The frames 4 carrying the brushes 3 on the spindle 2 are provided with a solid
wing upon one side which takes the place of one brush and serves to crowd the rivets
to and fro, while the brushes serve to sweep them into the discharge passages.
The feed conveying tubes-B-are connected to the discharge passages 5 as best
shown in Figs. 1, 2, 3, and 5, and at their lower extremity they are connected to the
semi-circular support-a-as best shown in Figs. 12 and 13 where their lower ends
are provided with cut-off mechanism, and the feed tubes discharge into the spring
discharge valves-b-secured to the supports-p-p-connected to the support-a¹-
which is secured to the upright portion-D-of the bracket-D.
C-C Figs. 1, 2, and 3 is the combined shoe. holder and riveting block, and the
same is located under the spring discharge valves-b-on the main frame-F-of the
machine immediately in front of the bracket-D.
The combined shoe holder and riveting block-C-C₁-is constructed and arranged
to support the shoe or arctic adjustable underneath the rivet forcing punches, and
is operated by mechanism hereinafter described to raise the overshoe to the rivet
forcing punches and to head the rivet.
The stock of the adjustable riveting block and combined adjustable shoe
holder C-C consists of the cylindrical tubular vertical section 1', and the angular
foot or arm constructed integral therewith as best shown in Fig. 23, and through
which the pivoting screw 6' passes which pivots the combined shoeholder and stock
to the frame of the machine.
The tubular vertical portion 11 of the stock has a tongue 13 on the interior as best
shown in the transverse sectional view Fig. 25, which in connection with a suitable
groove 12 in the screw 31 of the riveting block-C serves to guide the riveting
block C-rectilineally vertically without permitting the screw to turn in its upward
movement.
The combined riveting block and adjustable shoe holder consists of the anvil portion
or head-C-carrying the screw or shank 3¹. The threaded portion of the screw 31
fits down into the tubular portion of the stock 1', the tongue 13 of which engages
the groove 12 in the side of the screw for the purpose already explained.
2 is the adjusting nut threaded on its interior to engage the thread of the
screw 1', and it serves to raise or lower the riveting block by turning the same in the
usual manner.
The exterior of the adjusting nut 2¹ is provided with curved shaped serrations
which extend vertically from top to bottom of the adjusting nut and the spring 91
provided with the head 11 engages the serrations and prevents the nut from turning
in the operation of the mechanism.

page_text: The head of the riveting block is provided with apertures for the reception of dies 4'
Figs. 21 and 22 which fit into the apertures and serve to spread or clinch the prongs
of the rivets in the heading operation when the same are inserted in the arctics or
overshoes as will be presently explained.
Upon the side of the riveting block or anvil is secured a plate 71 which supports
one end of the spiral 81, the other end of which is secured to the stock 1' as illustrated
in Fig. 23.
The office of the spiral is to retract the anvil or riveting block when the same is
forced up in the operation of heading rivets.
C¹-represents the portion of the shoe holder which supports the toe and sole of the
shoe, the heel of which is supported on the riveting block-C, and the shoe holder
is made adjustable by providing the two parts connected with slots and screws as
best shown in Fig. 21.
It will be observed that the shoe holder may be readily adjusted for straining an
overshoe on to the anvil or riveting block by loosening the clamp screws and sliding
the supports one over the other to the length of the shoe, and that the shoe is firmly
held on the adjustable shoe holder or riveting block when the same is tightly strained
thereon in the manner explained.
In order to securely hold the riveting block and shoe holder under the feeding
mechanism, I provide the spring-m,best shown in Figs. 21 and 26, consisting of
the spring plate located underneath the stock, and having a stud-n-extending
upward from the spring plate and taking in a recess in the underside of the stock 1.
When the stock 1' is swung with the shoe under the feeding mechanism and the
punches, the stud-n-takes in the recess in the underside of the stock and securely
locks the stock in position for the heading operation, and by simply depressing the
handle or thumb piece of the spring-m-the stud-n-is released from its engage-
ment in the recess in the riveting block, and may be swung out from under the
feeding mechanism and punches, and the operation repeated.
The riveting block is forced upward in the heading operation by the plunger-P-
which will be presently explained, and in order to adapt the riveting block to the stroke
of the plunger, or in other words to adjust the same accurately for a given length of
rivet, the screw-p² is provided, which takes in a threaded seat in the screw 31
Fig. 26, which permits the adjustment of the stroke as desired. D-is the curved
bracket mounted on the main frame-F-provided with a vertical extension-D',-
and the same in connection with the vertical extension serves to support the feed
hopper or receptacle and the feed conveying and distributing mechanism together
with the punches for forcing the rivets into the overshoes, and their actuating
mechanism.
E is the treadle for actuating the various levers which serve to operate the.feed
and force the rivets into the arctics or overshoes.
F is the main frame upon which all of the mechanism is supported. G-is the
lever which serves to operate the plunger carrying the punches for forcing the
rivets into the shoes, and also the device in the feed hopper for feeding out
the rivets.
It accomplishes this through the medium of the toggle lever-g', the lever-G-
being pivoted at g-in the lugs provided at the upper extremity of the upright-D₁₁-
and pivoted to the toggle-gwhich is connected to the plunger-J-carrying the
head Jupon which are mounted the punches—c.
The lever G-is retracted to its normal position by means of the yoke or bale
shaped spring-N-best shown in the top plan view Fig. 4.
The brushes in the feed receptacle-A-are actuated when the lever-G-is
depressed by the shaft 2, being connected to the lover-G-through the medium of
the slotted lever 9 provided with a slot 10 which is pinned to the lever―n, and the
lever n is pivoted at-n-to the lever-K-which has a slot-k-and in which
the pin connected to the lever-G-slides as the lever-G-is depressed.
The lever K-is pinned at-k-to the bracket-D,-and as the lever G―is
depressed the lever-K-is oscillated on the pivot-k-and in turn oscillates the

page_text: The punches-c-c-are cylindrical in form, and are located so as to enter the
spring discharge valves-b, and are of sufficient length to force the rivets through
the discharge valves and into the arctic or overshoe held on the riveting block-().
When the treadle-E-is depressed the toggle levers-g-glare actuated by the
lever arm-G-to force downward the plunger-J-carrying with it the head-J
and the punches-c-c-attached thereto.
In this downward movement the support-a-carrying the fingers-d-causes the
fingers d to collide with the cut-off mechanism opening the feed tubes, and a rivet
which has been fed shank foremost into the tubes from the hopper receptacle, drops
down into the spring discharge valve-b-as the punches-c-c-rise above the
slots and the cut-offs immediately close the passage in-B-leaving the
rivets held in the spring discharge valves ready to be inserted in the arctic by
the descending punches, when the treadle is again depressed.
In order to guide the rivet accurately in its downward passage from the spring
discharge valve, we provide the pivoted forked yoke-0-having the arms oo
which embrace two sides of the spring discharge valves-bas best shown in
Figs. 16 and 17, and the yoke-0-is provided with the arm- -O'-pivoted at-o'—
and having the eccentric or angular lever--as best shown in Fig. 20.
It will be observed that the angular lever-v-is substantially at right angles with
the arm-0 of the pivoted yoke, and that it lies substantially on the line drawn
through the pivot-o-thereof and in the path of the lower edge of the
head J of the plunger-J-when the same descends as the treadle-E-is
depressed.
The object of pivoting the forked yoke-0-in the manner described and providing
the same with the angular lever-v-is to so arrange the pivoted yoke as to throw it out
of engagement with the discharge valve at the right instant to allow the passage of the
rivet from the discharge valve, and this is accomplished by the lower edge of the
plunger head colliding in its descent with the lever- of the pivoted
yoke O-which, owing to its relative position with the pivot-o'-throws the.
yoke O-out of engagement with the spring discharge valve-b-instantly and
permits the discharge of the rivet from the spring discharge valve as stated.
It will be observed that the exit ends of the feed are arranged on the circumference
of a circle described through the center of the riveting block as a center, and the
object of so arranging and locating the discharge ends of the spring valves and feed
conveying tubes B-is to arrange and distribute the rivets circumferentially on the
sole of the arctic or like overshoe, it being borne in mind that the purpose of the
invention is to provide an efficient machine which will simultaneously insert all of
the rivets which are necessary to insert in sole of the arctic or overshoe in one
operation.
It will be apparent that the object can be accomplished by so arranging the
mechanism as stated, since if, as illustrated in the example, it is desired to insert four
rivets at once, the discharge ends are arranged circumferentially as shown in Fig. 13,
and the necessary fingers-d-d-provided to actuate the cut-off valves-e-e, -and
a like number of punches being employed, it is obvious that the four rivets will be
fed downward simultaneously in the spring discharge valve, and from thence forced
into the heel or toe of the arctic or overshoe supported on the combined holder and
riveting block-C-in one and the same operation.
If it is desired to insert but one rivet into an arctic or overshoe, as for example
to rivet the stay of an arctic or overshoe, then but one feeding tube-B-is necessary,
and in this case a single set of the described mechanism can be employed, and at
Fig. 19 we have illustrated the mechanism thus arranged.
There is but one cut-off mechanism and one spring discharge valve, and in this form
we preferably make the discharge valve with an auxiliary spring-b-Fig. 19, as it
holds the rivet with sufficient firmness to direct the same into the stay of the arctic
without becoming displaced in the operation.
We do not restrict ourselves to the exact construction and arrangement of the
various parts of the mechanism which we have illustrated in this example of our

page_text: levers through the connection of the lever-n-with the lever-K, and this
movement oscillates the shaft 2, carrying with it the frame 4 and the dependent
brushes.
The lever G-is connected to the treadle-E-by means of the connection-h-
and the slotted guide-H. The combined holder and riveting block-C-C¹-is
operated to raise or lower by means of the toggle levers-I-i-i¹. The toggle
levers---are pivoted in the yoke-I-which is best shown in the detached
view Fig. 6. The yoke-I-is secured beneath the frame-F-as best shown in
Figs. 1 and 5 directly underneath the combined shoe holder and riveting block, and
the toggle levers-i¹—is secured to the plunger-P-which extends up into the riveting
block and serves to force up the riveting block in the riveting operation which will be
presently explained.
The lever arm-I-of the toggle lever sets,loosely in the slot of the guide-H-
as best shown in Fig. 9. The said slot--is of sufficient length to allow the
lever G-to be depressed to the right point when the rivet is forced into the arctic.
When the lever arm I collides with the upper end of the slot h¹ and is carried
down with it straightening the toggles i, and forcing up the plunger P and with it
the rivetting block C the plunger J and punch c are depressed thus crowding the rivet
down against the anvil, by which means the rivets are headed or clinched in the arctic
or overshoe.
The slotted guide H is secured to the treadle E at h³ by the connection h2, and the
lever arm I is retracted to its normal position by means of the spiral S¹, and the
treadle E is retracted to its normal position by means of the spiral S, and
the combined rivetting block and shoe holder is retracted to it normal position by
means of the spiral S₁ figures 2 and 3.
It will be observed that the front leg L of the machine is broken away for the
purpose of illustrating the yoke.
The lower or discharge ends of the feed conveying tubes B are arranged in the are
of a circle, and secured on the semi-circular bracket piece-a-as best shown in
Figures 12 and 13, and their exits come immediately over the spring discharge
valves b,there being a spring discharge valve b-for each tube-B, and the exit
ends of the tubes are so arranged in relation to the spring valves-b-as to feed the
rivets from the hopper into the spring discharge valve by means of the cut-off
mechanism as previously stated, which cut-off mechanism will be presently explained.
The spring discharge valves are located below the exit ends of the feed tubes-B-
and are secured to the sockets-p₁ of the dependent arms-p-which are secured
at a to the upright portion-D₁-of the bracket-D.
The spring discharge valves-b-are made of one piece of spring metal and are
bifurcated, the opening extending up far enough to permit the metal arms to spread
or spring sufficiently apart to allow the discharge of the rivets, and the discharge end
is provided with the enlargements---Fig. 16, which reduces the size of the exit
end or discharge, and serve in connection with the forked yoke-0-to guide the
rivet accurately in inserting it into the arctic or overshoe.
The spring discharge valve-b-has the slots-61-6-upon one side, as best shown
in Fig. 12, and the exit end of the feed conveying tubes-B-discharge into the slot
thus allowing the riveis to enter the discharge valves-b.
e
The feeding tubes-B-are provided immediately above the exit end-6-with a
cut-off valve and mechanism best shown in the enlarged detached views Fig. 14 in
which, is the eccentric lever pivoted at -on the side of the feed tube and
provided with the wing extensions--which takes in the bore of the tube, and a
spring mounted on the pivot screw-2- to retract the cut-off after the eccentric
end has been depressed.
The cut-off mechanism is automatically operated to let out one rivet at a time into
the spring discharge valves-6-by means of the fingers-d-attached to the
supporting piece-a-carried on the plunger head-J-of the plunger-J,--and the
cut-off mechanism is timed by the travel of the punches- -which are attached to
the head of the plunger-J-as best shown at Fig. 15.

page_text: invention, since the same may be changed at will without departing from the principle
of our invention.
The operation of our improved riveting machine will be readily understood from
the foregoing and from a consideration of the drawings.
The hopper or feed receptacle is filled with rivets and the treadle-E-is depressed
a few times until the discharge valves-b-are filled with rivets, after which, the feed
is substantially continuous.
If the series of feed conveying tubes-B-are employed as illustrated in our
present example of the machine, each feed tube is connected to the feed hopper as
described and shown, and each tube is provided with the spring discharge valve and
the cut-off mechanism herein described.
The over-shoe or arctic is secured onto the adjustable combined shoe holder and
riveting block-C-C-with the heel resting over the block-C-and the toe portion
setting over the adjustable arms-C-which may be adjusted to any length of arctic
or overshoe readily as previously explained.
The treadle-E-being depressed straightens the toggles-g-g-carrying down-
ward the plunger-J-and the punches-c-attached to the head-J, and the
fingers-d-attached to the support-a',-collide in their descent with the cut-off
mechanisme, thereby opening the passage and allowing another set of rivets to fall
into the spring discharge valves simultaneously with the pushing out of those already
occupying the discharge valves, or rather the rivets fall into the discharge valve proper
when the punches-c-are retracted out of the discharge valves, and the mechanism
is ready for another operation.
It will be understood that the punches force down and out of the discharge valves
the rivets already occupying the valves, and when the guide-H-strikes the lever
arm-I-the riveting block-C-carrying the shoe and shoe holder, is raised up, and
the rivets which are forced through the heel of the arctic are clinched or headed by
the collision of the punches and riveting block with the rivet between the two, and.
that the said punches and riveting block form what we term herein the heading
mechanism of the machine.
The riveting block-C-may carry any suitable die and plate for spreading or
clinching the rivets.
The springs-S-S-retract the treadle and lever arm-I,-while the bale
spring N-retracts the lever arm-G,-while the spiral-s-retracts the riveting
block C to its normal position.
All of the parts are compact and strong, and the machine is very effective and rapid
in its operation.
