Improvements relating to Riveting Machines.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of this invention to be as follows:-
This invention relates to machines for inserting rivets in two superposed layers to
be united, and supplying burrs or washers to the said rivets. The said rivets are
inserted from one side of the work and the burrs placed upon the opposite side thereof
the rivet shanks being inserted through the holes in the burrs and upset therein and
thus united to the burrs.
The said invention has for its object to provide an organized machine capable of
supplying the burrs to the upper side of the work, and of inserting the rivets from
the lower side so that the upset ends of the applied rivets will always be in view of
the operator, and to enable the burrs to be centred or positioned by the action
of the awl. To this end the invention consists in the improvements hereinafter
described.
The supporting frame, is provided with a work supporting bed or table and an over-
hanging arm or gooseneck. In the said arm is located a vertical hammer carrying a
slide which is provided with a hammer adapted to upset the ends of the rivets; the
snid slide being forcibly depressed by a spring composed, in this instance, of a series
of superposed leaves. One end of the said spring bears on a part of the frame, and
ts other end on the hammer carrying slide.
A yoke pivotally connected to the gooseneck, embraces the spring and has a screw
which bears upon the upper side of the spring and is capable of regulating the
orce thereof.
In the frame below the work supporting table are two vertical slides located side by
ide in a vertical guide in the frame. To the upper end of the slide hereinafter

page_text: Ine
termed the awl carrying slide is affixed an awl or punch to perforate the work.
said slide is reciprocated vertically by a cam on the driving shaft and a lever pivoted
to the supporting frame of the machine, the rear end of the said lever being held by a
spring against the cam while its opposite end enters a slot in the lower portion of the
awl carrying slide. The rotation of the driving shaft causes the cam to oscillate the 5
lever which in turn raises and lowers the slide and the awl or punch. The awl in
rising passes through an aperture in the work plate and through the material into a
burr or washer which is held against the upper side of the work, by means hereinafter
described.
The slide hereinafter termed the anvil carrying slide, located beside the awl carrying
slide has on its upper and a transverse head on which are horizontal dovetail guides.
Fitted to slide between the said guides is a block on which is an anvil upon which the
rivots to be inserted are placed, one at a time, by means heroinafter described. Tho
anvil carrying slide bears on a cam on the driving shaft and is raised and lowered by
the said cam.
The block which directly supports the anvil, rises and falls with the
anvil carrying slide and is reciprocated horizontally by means of a cam groove in a
disc on a vertical shaft which communicates motion from the driving shaft to a shaft
in the gooseneck, and a sliding rod having at one end a stud entering the cam groove
and connected at its other end with the anvil block by means of a vertical stud
projecting downwardly from the said block into an orifice in the rod the said connection
enabling the anvil block to rise and fall without the necessity of vertical movement
of the rod.
The anvil is provided with two jaws which are pivoted to the sides of the anvil
and are capable of meeting over the anvil to grasp the shank of an inverted rivet,
the head of which rests on the anvil. The meeting edges of the said jaws are
provided with cavities formed to receive the rivet shank, and said edges at one
side of said cavities are flared outwardly from each other to form a tapering slot
leading to the cavities, the outer end of the said slot being wide enough to permit the
entrance between the jaws of a rivet shank, so that when the said shank is pushed
between the jaws by the means hereinafter described the jaws will be forced apart
by the shank until the latter reaches the cavities and is grasped thereby.
The jaws are normally held closed above the anvil by a block which is pressed
upwardly by a spring against studs or pins attached to and projecting laterally from
the jaws. When the anvil is raised, as hereinafter described, the said block and
the pins strike a fixed arm attached to the frame and aro arrested by the said arm so
that the jaws open and release the rivet.
The rivet hopper is supported at the rear of the machino and from the said hopper
extends a raceway or channel through which the rivets pass from the hopper to the
devices which insert them in the material. The said raceway is composed of a bottom
plate and two parallel guides on the upper surface of the said plate, the said guides
being separated by a space of sufficient width to permit the passage between them of
the shanks of the rivets, while their inner edges are hevelled or undercut to
accommodate the heads of the rivets, the flat surfaces of the said heads sliding on the
bottom plate. The rivets therefore pass from the hopper to the inserting devices in an
inverted position and are inserted in the material in the same position, as hereinafter
explained.
The portion of the raceway leading from the hopper is inclined, so that the rivets
pass from the hopper by gravitation, while the remaining portion of the raceway is
substantially horizontal so that the rivets are moved horizontally under the work
supporting table and are thus kept near the plane of said table and therefore require
to be elevated by the anvil only a short distance to bo inserted in the work, as herein-
after described. The eyelets in the horizontal portion of the raceway are moved
positively forward by a feeding device. I prefer to use as the said feeding device a
positively reciprocated slide connected by an arm to the reciprocating rod which
reciprocates the rivet supporting anvil.
The feeding slide is timed to move the rivets exactly as fast as they are inserted in
the work. The rivets are transferred from the outer end of the horizontal portion

page_text: of the raceway to the anvil by a horizontally moving slide which is reciprocated in a
fixed guide, crosswise of the raceway, by means of the cam on the driving shaft,
a lever pivoted to an ear on the frame, a rod or slide interposed between the cam and
the lower end of the lever and a spring which presses the lever so as to normally
force its upper end away from the anvil. The upper end of the lever is engaged with
the rivet transferring slide by entering a slot in the said slide, so that when oscillated
by the combined action of the cam and spring it reciprocates the transferring slide.
When the said slide is drawn back the last rivet in the raceway is forced out in front
of the end of the slide by the rivet feeding device so that when the slide is forced
forward it pushes the said rivet through a short lateral guide communicating with the
outer end of the raceway, and inserts it between the jaws, its head resting on the
anvil and its shank projecting upwardly.
A slide is located beside the hammer carrying slide in the gooseneck and in contact
therewith. The said slide has at its lower end an offset tubular throat into which the
hammer projects.
A sleeve is adapted to slide on the said throat and extending below the same; the
said sleeve being provided with spring fingers formed to receive and hold between
them a burr or washer which is inserted between the said fingers by a feeling slide
reciprocated, by means hereinafter described, across the bottom of a vertical reservoir
adapted to hold a vertical column of burrs.
The burr holding sleeve is pressed downwardly by a spring, its downward move-
ment being limited by a headed pin attached to its upper end and sliding through a
socket in a collar rigidly attached to the throat the head of the pin hearing against
the upper surface of the collar. The sleeve is therefore capable of yielding upwardly
when pressed against the work, as hereinafter described, thus accommodating itself to
the thickness of the work. The slide supporting the burr holding sleeve is reciprocated
vertically by a cam groove in a disc on the shaft journalled in the arm or gooseneck.
When the slide is raised by the said cam groove its offset lower end bears on the
lower end of the hammer slide and raises the latter until an arm on the hammer
slide is engaged by a spring actuated latch on a rockshaft the said latch engaging
automatically with the arm and holding the hammer slide elevated until it, the latch,
is moved to disengage it from said arm and release the hammer slide by contact of a
stud on the rear side of the disc with an arm on the rockshaft. A spring on the said
rockshaft gives the latter a tendency to turn in the direction required to engage the
atch with the arm of the hammer slide. The burrs are supplied to the reservoir
from a hopper, which is supported at its rear end by a bracket attached to the
gooseneck. The said hopper is attached at its forward end to the bracket and is
vertically adjustable at its rear end by means of a screw working in the outer end of
he bracket In this way the inclination of the hopper may be varied.
The burrs are caused, by the jar attending the operation of the machine, to slide
lown the inclined hopper and drop from thence into the reservoir. The slide that
eeds the burrs from the reservoir to the holding fingers on the sleeve is reciprocated
orizontally in guides on the bracket by means of a lever pivoted to an ear on the
ooseneck and having one arm jointed to the slide and its other arm arranged in the
ath in which a stud on the rear side of the disc travels. When the said stud
ncounters the lever it turns the latter on its fulcrum, so that the lever pushes the
ide forward and causes its forward end to move the bottom burr from the column
the reservoir and push it under a spring depressed presser foot to the spring
ngers of the sleeve. The slide is of greater thickness than a burr and has in its
pper surface, at its forward end, a recess of a depth nearly or quite equal to the
ickness of a burr. The lowest burr in the column drops into the said recess and
mains in it until it is thrust between and grasped by the spring fingers. After the
arr feeding movement of the slide the stud passes by and releases the lever where-
on a spring forces the said lever in the opposite direction and causes it to force the
de back, its recess again receiving the bottom burr in the reservoir.
The operation of the machine above described is as follows:
The superposed layers of material to be rivetted, such as the ends of a piece of

page_text: belting, are placed on the work table and the burr holding sleeve having a burr
inserted between its spring fingers is depressed and caused to bear upon the upper
surface of the work, thus holding the latter in position on the work table. The awl
or punch then rises and perforates the work, the hole coinciding with the hole in the
burr held by the fingers. After the awl recedes the anvil, having a rivet between its 5
jaws, is moved horizontally until the rivet stands exactly under the hole in the work.
The anvil is then raised by the slide, the shank of the rivet being thus inserted in the
hole in the work and in the burr. While the anvil is raised the hammer descends
and upsets the end of the rivet shank, thus uniting the rivet and burr. The anvil is
then lowered and drawn back, and the slide having the burr holding sleeve is raised, 1
its offset lower end bearing against the haminer slide and raising the latter. The
hammer slide is engaged by the latch and thus retained in its raised position. A burr
is then inserted between the fingers of the burr holding sleeve, and a rivet is trans-
ferred to the anvil and held by the jaws and thus the operation is continued.
It will be seen from the foregoing that the eyelets are presented with their points
upwardly, and inserted from the underside of the work, the burrs being on the upper
side. The operator is therefore enabled to see whether each rivet is properly engaged
with a burr without the necessity of turning the work over and looking at its under
sido, as is necessary when the rivets are inserted from the upper side of the work as
heretofore.
To cause the rivets to pass properly from the hopper into the inclined portion of the
raceway, I provide at the upper end of the latter an agitator consisting of a rotating
shaft journalled in suitable fixed bearings and provided with an enlargement in
which are set a number of pins which stand in planes at right angles to the axes
of the shaft but are diagonally arranged. The agitator is arranged over the inclined
lower portion of the hopper and is rotated by a belt running from a pulley on one
shaft to a pulley on another shaft. The arrangement of the pins are such that a
rivet cannot pass down the inclined portion of the hopper under the agitator unless
it rests on its head with its shank projecting upwardly. A partition under the
agitator, divides the passage through which the rivets pass under the agitator into
two parts, each of which is of sufficient width for the passage through it of one
rivet at a time. The rotating agitator stirs the rivets that gravitate against it, and
such of the rivets as are caused by the agitator to assume the said position down into
the raceway, which is kept full by the continuous operation of the agitator. A casing
partially covers the agitator and a comb shaped plate having teeth projecting over the
side of the agitator next to the reservoir, prevents the rivets from getting caught
between the pins and carried out of the receptacle by the rotation of the agitator. 1
prefer to make the heads of the rivets overlap each other in the horizontal portion of
the raceway so that they will be closely packed and will not be likely to be displaced.
To this end 1 secure a spring to the raceway, the free end of said spring projecting
over the channel in the raceway and being formed to bear against the upper ends of
the rivets and tip them and cause their heads to overlap the rivet head supporting
surface of the raceway being provided with a recess which facilitates the overlapping
of the rivet hends.
I prefer to provide the machine with a work feeding lever pivoted to an ear on the
gooseneck and having a foot jointed to its lower end and bearing on the work. The
upper end of said lovers bears against the periphery of the disc and is moved inter-
mittingly by a cam on said disc, and is thus caused to feed the work. The foeding
lever may be arranged to bear against either side of the disc instead of against. its
periphery in which case the disc would be provided with a cam on the side against
which the feed lever bears, and would oscillate the lever at right angles to the
direction in which it is oscillated by the cam.
In a modification of the mechanism for reciprocating the anvil horizontally and
for feeding the rivets through the horizontal portion of the raceway, and for operating
the slide or feeder that transfers the rivets from the raceway to the anvil, the rive
feeding device is a horizontal disc having a series of rivet shank receiving pockets i
its periphery. The said disc is mounted on a stud affixed to the frame and project
•

page_text: into the raceway, so that each of its pockets receives a rivet from the lower end of the
inclined portion of the raceway. The disc is rotated step by step hy a pawl carrying
lover mounted to oscillate loosely on the shaft to which the disc is affixed, and a ratchet
affixed to the said shaft and engaged by the pawl on the said arm.
The arm and its pawl are oscillated by a rod connecting the said arm to a lever which
is pivoted to the frame of the machine and is engaged by a stud on one of its ends
with the cam groove in the disc. The oscillations of the lever caused by the rotation
of the disc, are imparted to the arm and its pawl and thus the disc is rotated step by
step and caused to feed the rivets along the horizontal raceway. The anvil carrying
block has a stud on its rear end which enters a cam shaped slot in a lever which is
mounted to oscillate on a stud on the frame and is connected by a rod with the oscil-
lating lever, so that the lever connected to the oscillating lever is oscillated by the said
oscillating lever the slot being formed to convert the oscillating movements of the
lever into rectilinear movements of the anvil block.
The rivet transferring slide has a stud which enters a slot in one end of a
lever which oscillates on a stud or pivot on the frame and has a curved arm which is
engaged by a stud on an arm pivoted to an arm on the lever connected to the oscillating
lever. The said arm has a stop which is normally held by a spring against one edge
of the lever arm the spring permitting the arm to yield. When the levor is turned
in one direction the arm is moved by the said lever until the stud or roller at its
outer end passes by the end of the curved arm, whereupon the spring draws the arm
into line with the lever arm and causes the stop to bear against said arm.
roller then bears against the outer end of the curved arm and when the lever is
moved in the opposite direction it causes the arm to swing and thus cause the slide
to transfer a rivet to the anvil. A spring draws the said slide back when the
lever is released.
The
In another form or modification of the rivet feeding mechanism which consists
of a large wheel having pockets in its periphery to receive the rivets from the
inclined portion of the raceway, and of sufficient diameter to extend across from
the said inclined portion to the anvil. The wheel is rotated step by step by the
oscillating lever and a three armed lever mounted on the axis of the wheel and
having one of its arms connected by a rod to the lever and another arm provided
with a pawl which engages with a ratchet affixed to the axis of the wheel. The third
arm of the lever has a cain shaped slot which receives a stud on the anvil carrying
block and reciprocates the said block. When the anvil is moved back from the
position it occupies when holding the rivet for the action of the hammer, it is under
the margin of the wheel so that the pockets will come successively over the anvil,
each stoppage of the wheel occurring when one of its pockets is over the anvil. On
the anvil is a sleeve which is pressed upwardly by a spring, so that its rear edge
which is higher than its front edge bears against the rear of the rivet head and
pushes the rivet along when the anvil is moved horizontally.
The block supports a bearing in which is journalled a rockshaft, having at one
end an offset finger which is pressed downwardly by a spring on the rockshaft
against the front portion of the head of the rivet placed on the anvil; the said head
being moved under the finger when it is carried upon the anvil. When the block
is moved forward and raised, an arm on the rockshaft strikes the fixed arm and is
turned with the rockshaft so as to raise the finger from the rivet head. One side
of the raceway is extended along the periphery of the wheel to the anvil, as a guard
to retain the rivets in the pockets of the wheel. It will be seen that by this
construction the transferring slide is dispensed with.
The rivet reservoir may be constructed substantially like that used in eyeleting
machines, and having an oscillating agitator armed with tufts of bristles. One side
of the reservoir has ports formed to permit the passage of the inverted rivets into
the raceway.
It is obvious that various other modifications may be made in the details of the
machine without departing from the spirit of the invention. Instead of making the
punch and awl interchangeable in position they may be arranged to act at different

page_text: points, the rivet hole being made at a distance from the anvil and brought over the
anvil by a movement of the work. It is possible to use the machine without the
work plate, but the latter is highly desirable, as will be readily seen.
I do not confine myself in all cases to the provision of means for holding the burr
stationary and forcing the rivet into it, as if desired the burr may be forced
downwardly on to the rivet, the latter being held stationary.
Two or more rivets may be placed on the anvil at once, the latter being made of
suitable size to receive them. In this case a like number of burrs should be supplied
simultaneously and the upsetting device should be correspondingly enlarged to act
on all the rivets on the anvil.
The burr hopper may be oscillated or shaken by special devices provided for that
purpose instead of by the jar of the machine alone.
It is obvious that the machine may be used for some purposes without burr
supplying devices, for example in riveting together thicknesses of sheet metal, such
as the overlapping ends of metal barrel hoops.
It will also readily appear that the upsetting hammer may be forced down by
other means than by the spring. It will be observed that by arranging the awl or
punch and the rivet inserting anvil below the work, and the upsetting device or
hammer above the work, feeding the rivets in an inverted position to the anvil below
the work, and providing independent devices for operating the awl or punch and the
anvil so that they may be interchanged and operated in quick succession, I am
enabled to perform the entire operation of punching, inserting the rivet and
upsetting the end of the rivet during one rotation of the driving shaft of the
machine, the punch and aw! acting alternately in quick succession to form a hole
and insert a rivet therein during a part of the rotation of the driving shaft,
while the upsetting hammer acts to upset the rivet during the completion of the said
rotation.
It will be seen that the awl in piercing the work enters the hole in the burr on
the upper side of the work, and thereby enters the burr or moves it to the exact
position required to cause it to coincide with the rivet shank when the latter is
inserted. This feature of my invention is one of much importance.

I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co. Patent Agents,
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 statenient :-
This invention relates to machines for inserting rivets in two or more superposed
layers to be united and supplying burrs or washers to the said rivets, the rivets
being inserted from one side of the work and the burrs placed on the opposite side,
the rivet shanks being inserted through the holes in the burrs and upset therein, and
thus united to the burrs.
In rivetting-machines as heretofore constructed the organization has been such that
the operations of making the holes for the rivets, inserting the rivets in the said holes,
and upsetting the ends of the rivets have required not less than two rotations of the
driving-shaft, thus making the operation slower than is desirable, and the rivets have
been inserted in the work from the upper sido thereof so that the operator has been
obliged to turn the work to see if the burrs have been properly engaged with the
rivets.
The said invention has for its object to enable the operations of punching the holes
and of inserting and upsetting the rivets to be performed during a single rotation of
the driving shaft, and thus make the operation of the machine more rapid than
heretofore.
The invention also has for its object to provide an organized machine capable of
supplying the burrs to the upper side of the work and of inserting the rivets from
the lower side-so that the upset ends of the applied rivets will always be in view of
the operator.
To these ends the said invention consists in the improvements which are hereinafter
described.

Figure 14 represents a section on line y¹ y' Figure 13.
Figure 15 represents a sectional view of a portion of the rivet-race, showing a means 5
of tilting the rivets.
The same letters of reference indicate the same parts in all the Figures.
a represents the supporting frame, having a bed or table b and an overhanging arm
or goose neck c. In the arm c is located the vertical hammer-carrying slide d, which
is provided with a hammer e adapted to upset the ends of the rivets the said slide being
forcibly depressed by a spring, composed in this instance of a series of superposed
leaves. One end of the said spring bears on a part of the frame and its other end on
the hammer-carrying slide d. A yoko 9 pivotally connected to the goose-neck
embraces the spring and has a screw h which bears upon the upper side of the spring
and is capable of regulating the force thereof.
In the frame, below the work supporting table b are two vortical slides ij located
side by side in a vertical guide in the frame. To the upper end of the slide i is affixed
an awl or punch k to perforate the work. The slide i is reciprocated vertically by a
cau Figure 1, on the driving shaft m and a lever n, pivoted at o to the supporting-
frame of the machine, the rear end of said lover being held by a spring p, against the
cam 1, while its opposite end enters a slot 9 Figure 2, in the lower portion of the awl-
carrying slide i. The rotation of the driving-shaft causes the cam to oscillate the
lever n, which in turn raises and lowers the slide i and the awl or punch. The awl in
rising passes through an aperture in the work-plate and through the material into a
burr or washer, which is held against the upper side of the work by means hereinafter
described.
The slidoj located beside the awl-carrying slide, has on its upper end a transvorso
head t, on which are horizontal dovetail guides uu. Fitted to slide between said
guides is a block v, on which is an anvil w, upon which the rivets to be inserted are
placed by means hereinafter described. The anvil-carrying slide bears on a cam a¹, on
which
the driving shaft m and is raised and lowered by said cam. The block
directly supports the anvil, rises and falls with the slide j, and is reciprocated
horizontally by means of a cam-grove 6', in a disc c on the vertical shaft d, which
communicates motion from the driving shaft m to the shaft e' in the goose neck and a
sliding rod, having at one end a stud entering the can-groove 61, and connected at
its other end with the anvil-block by means of a vertical stud g₁ projecting down-
wardly from said block into an orifice in the rod f, said connection enabling the anvil-
block to rise and fall without the necessity of vertical movement of the rod.
The anvil w is provided with two jaws h¹ h', which are pivoted to the sides of the
anvil at Figure 11, and are capable of meeting over tho anvil to grasp the shank
of an inverted rivet, the head of which rests on the anvil Figure 10. The meeting
edges of said jaws are provided with cavities j¹ j¹, Figure 11, formed to receive the
rivot-shank, and said edges at one side of said cavities are flared outwardly from cach
other to form a tapering slot leading to the cavities, the outer end of said slot being
wide enough to permit the entrance between the jaws of a rivet-shank, so that when
the said shank is pushed between the jaws by the means hereinafter described the jaws
will be forced apart by the shank until the latter reaches the cavities jj and is
grasped thereby.
The jaws are normally held closed above the anvil by a block k¹ which is pressed
upwardly by, a spring 1', against studs or pins m² m² attached to and projecting
laterally from the jaws. When the anvil is raised, as hereinafter described, the said
block and the pins m¹ m² strike a fixed arm n¹ attached to the frame, and are arrested by
said arm, so that the jaws open and release the rivet, as shown in Figure 11.
From the said
o¹ represents the rivet-hopper, supported at the rear of the machine.
hopper extends a raceway or channel p' through which the rivets pass from the hopper
to the devices which insert them in the material. Said raceway is composed of a
bottom plate and two parallel guides on the upper surface of said plate, said guides

page_text: being separated by a space of sufficient width to permit the passage between them of the
shanks of the rivets, while their inner edges are bevelled or under-cut to accommodate
the heads of the rivets, the surfaces of the said heads sliding on the bottom plate. The
rivets therefore pass from the hopper to the inserting devices in an inverted position
and are inserted in the material in the same position, as hereinafter explained.
The portion of the raceway leading from the hopper is inclined, so that the rivets
pass from the hopper by gravitation, while the remaining portion of the raceway is
substantially horizontal, so that the rivets are moved horizontally under the work-
supporting table and are kept near the plane of said table, and therefore require to be
elevated by the anvil only a short distance to be inserted in the work, as hereinafter
described.
The rivets in the horizontal portion of the raceway are moved positively forward by
a feeding device hereinafter described, though other equivalent means could be
employed. I prefer to use as the said feeding device a reciprocating slide q¹ connected
by an arm to the reciprocating rod f' which reciprocates the rivet-supporting anvil.
The feeding-slide q' is timed to move the rivets exactly as fast as they are inserted
in the work. The rivets are transferred from the outer end of the horizontal portion
of the race way to the anvil w by a horizontally-moving slide s which is reciprocated
in a guide crosswise of the raceway by means of the cam a¹ on the driving shaft, a
lever u¹ pivoted at vi to an ear on the frame a, a rod or slide o interposed between
the cam a and the lower end of the lever u', and a spring a which presses the lover
so as to normally force its upper end away from the anvil. The upper end of the
lover is engaged with the rivet-transferring slide by entering a slot in said slide, so
that when oscillated by the combined action of the cam a¹ and spring a³ it reciprocales
the transferring slides. When said slide is drawn back, the last rivet in the raceway pl
is forced out in front of the end of the slide by the rivet-feeding device q' so that
when the slide s¹ is forced forward it pushes said rivet through a short lateral guide 62,
communicating with the outer end of the raceway, and inserts it between the
jaws h¹h, its head resting ou the anvil and its shank projecting upwardly, as shown
in Figure 10.
represents a slide located beside the hammer carrying slide in the goose-neck c
and in contact therewith. The slide c³ has at its lower end an offset tubular throat, d
Figure 6, into which the hammer e projects.
e² represents a sleeve adapted to slide on the said throat and extending below the
same, the said sleeve being provided with spring-fingers ff, formed to receive and
hold between them a burr or washer 9 Figure 8, which is inserted between said
fingers by a feeding slide reciprocated by means bereinafter described, across the
bottom of a vertical reservoir adapted to hold a vertical column of burrs. The
burr-holding sleeve e is pressed downwardly by a spring its downward movement
being limited by a headed pin Figure 9 attached to its upper end and sliding
through a socket in a collar rigidly attached to the throat d², the head of the pin k*
bearing against the upper surface of the collar 1. The sleeve is therefore capable
of yielding upwardly when pressed against the work as hereinafter described, thus
accommodating itself to the thickness of the work.
The slide supporting the burr-holding sleeve is reciprocated vertically by a cam-
groove m² in a disc n² on the shaft e journalled in the arm or goose-neck. When the
slide c² is raised by the said cam-groove, its offset lower end bears on the lower end
of the hammer slide d and raises the latter antil an arm o' on the hammer-slide is
engaged by a spring-actuated latch p² on a rock-shaft q², said latch engaging
automatically with the arm o' and holding the hammer-slide elevated until the latch is
moved to disengage it from said arm and release the hammer-slide by contact of a
stud Figures 2 and 3, on the rear side of the disc n³ with an arm on the rock-
shaft q. A spring on the rock-shaft q' gives the latter a tendency to turn in the
direction required to engage the latch p³ with the arm of the hammer-slide d.
The burrs are supplied to the reservoir from a chute or tray u² which is
supported at its rear end by a bracket attached to the goose-neck e. The said

inclination of the hopper may be varied.
In this way the
The burrs are caused by the jar attending the operation of the machine to slide
down the inclined chute or tray and drop from thence into the reservoir . The
slide that feeds the burrs from the reservoir 2 to the holding fingers on the
sleeve, is reciprocated horizontally in guides on the bracket v² by means of a lever a³
pivoted at 63 to an ear on the goose-neck and having one arm jointed to the
slide h² and its other arm arranged in the path in which a stud on the rear side of
the disc n² travels. When said stud encounters the lever a³, it turns the latter on its
fulcrum, so that the lever pushes the slide 2 forward and causes its forward end to
move the bottom burr from the column in the reservoir and push it under a
spring depressed presser-foot e³ to the spring-fingers of the sleeve e. The slide h²
is of greater thickness than a burr and has in its upper surface at its forward end
a recess of a depth nearly or quite equal to the thickness of a burr. The lowest burr
in the column drops into said recess and remains in it until it is thrust between and
grasped by the spring fingers ff. After the burr feeding movement of the slide h³
the stud passes by and releases the lever as whereupon a spring ³ forces said lever
in the opposite direction and causes it to force the slide back to the position shown
in Figure 9, its recess again receiving the bottom burr in the reservoir .
The operation of the machine above described is as follows. The superposed layers
of material to be riveted such as the ends of a piece of bolting are placed on the
work-table and the burr-holding sleeve, having a burr insorted between its spring
fingors, is depressed and caused to hear upon the upper surface of the work, thus
holling the latter in position on the work-table. The awl or punch then rises and
perforates the work, the whole coinciding with the hole in the burr held by the
fingers ff. After the awl recodes, the anvil having a rivet between its jaws is
moved horizontally until the rivet stands exactly under the hole in the work. The
anvil is then raised by the slide j, the shank of the rivet being thus inserted in the
hole in the work and in the burr. While the anvil is raised the hammer e descends
and upsets the end of the rivet-shank, thus uniting the rivet and burr. The anvil
is then lowered and drawn back, and the slide chaving the burr-holding sleeve,
is ruised, its offset lower end bearing against the hammer-slide d and raising the
latter. The hammer-slide is engaged by the latch p³, and thus retained in its
raised position. A burr is then inserted between the fingers of the burr-holding
sleeve, and a rivet is transferred to the anvil and held by the jaws h¹ h¹ and thus
the operation is continued.
It will be seen from the foregoing that the rivets are presented with their points
upwardly and inserted from the under side of the work, the burrs being on the upper
side. The operator is therefore enabled to see whether each rivet is properly engaged
with a burr without the necessity of turning the work over and looking at its under
side, as is necessary when the rivets are inserted from the upper sido of the work, as
heretofore. To cause the rivets to pass properly from the hopper o¹ into the inclined
portion of the raceway p', I provide at the upper end of the latter an agitator consisting
of a rotating shaft journalled in suitable fixed bearings and provided with an
enlargement in which are set a number of pins, which stand in planes at right
angles to the axis of the shaft 3, and may be arranged as clearly shown in Figure 13.
The agitator is arranged over the inclined lower portion of the hopper, and is rotated
in the direction indicated by the arrow in Figure 13 by a belt running from a
pulley, on the shaft e¹ to a pulley 13 on the shaft Figure 1. The arrangement of
the pins is such that a rivet cannot pass down the inclined portion of the hopper
under the agitator unless it rests on its head, with its shank projecting upwardly, as
shown in Figures 13 and 15.
A partition m³, under the agitator divides the passage through which the rivets pass
under the agitator into two parts, each of which is of sufficient width for the passage
through it of one rivet at a time. The agitator stirs the rivets that gravitate against
it, and such of the rivets as are caused by the agitator to assume the position indicated
slide down into the raceway, which is kept full by the continuous operation of the

page_text: agitator. A casing o³, partially covers the agitator, and a comb-shaped plate p³ having
teeth projecting over the side of the agitator next to the reservoir, prevents the rivets
from getting caught between the pins and carried out of the receptacle by the
rotation of the agitator.
I prefer to make the heads of the rivets overlap cach other in the horizontal
portion of the raceway, as shown in Figure 15, so that they will be closely packed
and will not be likely to be displaced. To this end I secure a spring to the raceway,
the free end of said spring projecting over the channel in the raceway and being
formed to bear against the upper ends of the rivets and tip them and cause their heads
to overlap, as shown, the rivet-head-supporting surface of the raceway being
provided with a recess w³, which facilitates the overlapping of the rivet-heads.
I prefer to provide the machine with a work-feeding lever ³, pivoted at ³ to an
ear on the goose-neck, and having a foots, jointed to its lower end and bearing
on the work. The upper end of said lever bears against the periphery of the
disc n² and is moved intermittingly by a cam on said disc, and is thus caused to
feed the work. The feeding lever may be arranged to bear against either side of
the disc n² instead of against its periphery, in which case the disc would be provided
with a cam t, on the side against which the feed lever bears, and would oscillate
the lever at right angles to the direction in which it is oscillated by the
cam t³
It will also readily appear that the setting-hammer may be forced down by other
means than by the spring f. It will also be observed that by arranging the awl
or punch and the rivet inserting anvil holow the work and the upsetting device or
hammer above the work, feeding the rivets in an inverted position to the anvil below
the work, and providing independent devices for operating the awl or punch and
the anvil so that they may be interchanged and operated in quick succession, I am
enabled to perform the entire operation of punching inserting the rivet, and
upsetting the end of the rivet during one rotation of the driving shaft of the machine,
the punch and awl acting alternately in quick succession to forin a hole and insert a
rivet therein during a part of a rotation of the driving-shaft, while the upsetting-
hammer acts to upset the rivet during the completion of said rotation.
The rapidity of operation resulting from the arrangement just indicated is the chief
advantage of this invention, although the capability of seeing the burrs on the upper
side of the work previously referred to is also a very important advantage secured by
the described organization of the machine.
