Machines for Boring Holes in Buttons.
1, DILMAN BRUBACHER SHANTZ, of Queen Street, in the Town of Berlin, in
the Province of Ontario, Canada, Manufacturer, do heroby 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 improvements in machines for boring holes in buttons
and similar articles and the object of my invention is to provide a convenient
automatic means of feeding the buttons into position between the stationary and
movable chuck in which they are held for boring and thereby effect the saving of
time and labor and at the same time prevent the frequent spoiling of the button
incident to it being fed by hand into position between the chucks and it consists
essentially of a chute, the lower end of which is provided with a downwardly
extending belding plate designed to co-act with the upper extension of the
stationary holding chuck, peculiarly operated arms being provided which are also
designed to grip and lower the button into position between the stationary and
movable chuck, and further in providing at the upper end of the chute a feed
hopper in which the buttons are placed, which hopper is provided with rotating
arms designed to facilitate the feed and placing of the buttons from the hopper
into their proper position in the chute and the various supplemental parts being
otherwise constructed to co-act with the above mechanism in the manner hereinafter
more particularly explained.
Fig. 1, is a perspective view of a portion of my machine for boring holes in
buttons showing the attachment for the automatic feed of the buttons.
Fig. 2, is a sectional perspective view.
Fig. 3, is a sectional detail of the top of the chute showing the form of the
adjustable selecting plate to secure the proper deposit of the button from the
hopper into the chute.
Fig. 4, is a perspective detail showing the meaus for adjusting the sides of
the chute.
Fig. 5, is a perepective detail of the front disc of the hopper and the arc-shaped
guiding rings.
Fig. 6, is a perspective detail of the sprocket for driving the rotating arms in
the hopper showing its peculiar connection to the worm wheel shaft.
In the drawings like letters of reference indicate corresponding parts in each
figure.
A is the bed-plate of the machine and B B' are the standards on which are
supported the inner ends of the drill spindles. C is a bracket having attached
thereto an adjustable supplemental bracket C through which the free ends of the
drill spindles D pass. E is the standard at the top of which is supported the
adjustable drill holder F through which pass the outer ends of the drills G.
H is an arbor, which has secured at one end the worm wheel I, which meshes
with the worm J on the main driving shaft K of the machine. On the arbor H
is secured the cams L and M, which regulate the movement of the lever Q, the
gripping fingers for the blank and the backward and forward movement of the
carriage P. The carriage P is supported on the base plate between suitable
guide-ways and gives a backward and forward movement.
The lever Qis pivoted near the bottom at 7 on the forward end of the

page_text: carriage P. R is a chuck secured in the ring-shaped top of the lever Q. y' is a
spiral spring, which extends into a recess in the carriage P and is designed to
press upon the lever Q. S is a lever pivoted at s in the lugs forming part of the
bed-plate A. The lever S of course extends through the bed-plate and is provided
at the lower end with a roller s journalled in jaws s', which roller is designed to
have frictional contact with. the cam L. T is a rod, which has a beut end t,
which extends into the lever Q. The opposite end of the rod is threaded and is
provided with an adjustable collar . The threaded end of the rod T extends
freely through an opening in the lever S.
U is a plate secured on the end of the forwardly extending portion P' of the
carringe P. The plate U is reduced in size at its upper end and extends vertically
upwords into the front side V of the hopper V. The plate U forms the front
side of the chute U.
The hopper V is provided at its exterior with a bracket W, which is secured to
the vertical rod Wwhich extends upwardly from and is secured to the carriage P.
It will thus be seen that the hopper V is supported by means of the bracket W and
vertical rod W upon the carriage.
X is a spindle, which extends through the hopper V as shown and is journalled
at one end in the bracket W in which it is held from moving longitudinally by
meaus of the collar. The opposite end of the spindle X extends through and is
secured to the hub v of the 'dise V' at the front side of the hopper V and an
arm V' attached to or forming part of the bracket Y, which is suitably secured on
the vertical spindles WW. The spindle X is provided with a sprocket wheel X',
which is connected by a sprocket chain X' to a sprocket wheel X secured on the
extension H' of the arbor H. The extension H' of the arbor H is connected by a
toggle-joint to the arbor H and is journalled at its opposite end in an arm ¹
secured to the frame of the machine (see Fig. 6).
By means of the cross sprocket chain X it will be seen that the spindle X
derives its rotation from tlie arbor H.
W is a vertical rod, which is also secured at the bottom to the carriage P and
also extends through the bracket Y, which it also serves to support. The bracket Y
is provided with an outwardly extending wing Y, through which extend the sut
screws y. The inner ends of the set screws y are provided with annular grooves y
into which extend the plate y, which is secured by the screws y' to the rear side Ü
of the chute U. By means of the set screws y the rear plate U may be adjusted
in relation to the front plate U¹ in order to accommodate different thicknesses of
buttous. Y is a spring plate having a. forked lower end y, which extends into
proximity with the plate U. Y is a slot in the plate Yaud Y is a set screw
which extends through the slot Y into the plate U, such set sorow being designed
to be loosened in order to adjust the height of the forks Y. The upper end of
the bracket Y is formed with a level plate Y above the wing Y, such plate
having a vertical inner end y, which is provided with a slot y, the bottom of
which is formed by the top of the plate. y' is the outer up-turned end of the
plate Y
Z is a plate, which lies upon the plate Y and has a broad V-shaped notched
inuer end, which extends into and forms a guide at one side of the chute U' in
order to ensure the convex portion of the button coming down on the side in which
the notch is formed and the fat portion of the button going down on the opposite
Bide necessarily. The plate Z is held down by the top of the slot y' and is held
from lateral movement by the plug y (see Fig. 1). The plate Z is adjusted
longitudinally by means of a set screw 2, which extends through the up-turned
end y' and has a reduced end provided with a knob, which reduced end extends
through an eye z attached to or forming part of the plate Z. By means of the
set screw 2 the plate Z may be adjusted in the chute to accommodate the different
thicknesses of buttons.
The disc V herein before referred to is provided with a peripheral groove v',
which fits a tongue u at the top of the pluto U. 2 is a ring connected by the

page_text: arms 3 to the hub 4 secured to the spindle X. The ring 2 at one side abuts the
edge of the circular opening V made in the front V of the hopper V. At
the opposite side the ring 2 abuts the arc-shaped guide 5 attached to or forming.
part of the bracket 6, which is secured to the front V of the hopper. The
bracket 6 straddles the disc V' and is provided at its outer end with an arc-shaped
guide 7, which abuts the disc V¹. 8 is a finger which is located at the inner side
of the disc aud has a plate 9 which extends through a slot 10 made in the disc V'.
The plate 9 is attached to or forms part of the detent 10 pivoted at 11 on the
outside of the disc V. 12 is a spring, which is fastened at one end to the disc V¹
and at the opposite end to the detent 10, the object of the spring 12 being to cause
the detent to have an outward pressure against the are-shaped guide-way 7.
As the spindle X is caused to revolve it carries with it the ring 2 and disc V¹.
The buttons, which are in the hopper are kept continually stirred up or more
properly prevented from wedging or sticking by the arms 3. The buttons are
carried down between the ring 2 and the disc V. If a button should not be carried
down with the flat face next the disc and the plate U and the convex face next
the broad V-shaped notch in the plate Z it will necessarily stick. In order to
remove this button and allow of a button, which is properly placed in the top of
the chute to pass down to such chute I provide as hereinbefore described the
finger 8, which as the disc V revolves is carried around with it and is forced
outwardly at the bottom when the detent 10 is relieved from contact with the
arc-shaped guide-way 7. This outwardly extending movement of the finger 8 will
carry the button away from the chute as such finger will pass out to the periphery
of the disc. As the finger 8 passes onwardly in ite revolution and as the disc
rototes in the direction indicated by arrow such button will be carried upwardly
circumferentially until the finger is pressed inwardly through the detent 10, where-
upon the arc-shaped guide-way 5 will carry such button within the vortex of the
circularly moving disc against which all the buttons are pressing and such button
I find in practice will turn eventually as will all of the buttons and pass down
into chute with the face towards the disc and the convex portion towards the
ring, so that such button may pass the broad V-shaped selecting plate Z.
In order to further ensure of the improperly deposited button from sticking
above the selecting plate I provide au arm 13, which is pivoted at 14 on a plate 15
and is also pivotally connected to such plate by a pin 18 extending through a
slot 17 in the arm 13. The arm 13 extends upwardly in the position shown in
Fig. 2 into a slot u' made in the front side of the plate U of tho chute U¹, such
slot being a vertical one and preferably extending above and below the level of
the selecting plate Z. The plate 15 is pivoted on the pin 16 and is connected by
a pin 171 to a rod 18, the front end of which is preferably slightly curved, so as to
extend around the head of the pin 16', so as to hold the plate 15 firmly on its geat
and yet not prevent its swinging movement. The rod 18 extends through a holo
in the top of the rod 19 secured in the top of a standard B. 20 are collars seenred
to the rod on each side of the standard by a set screw and 21 are spiral springs
extending between the collars and the rod 19. The springs 21 are designed to
relieve the pressure from the end of the arm 14.
Upon each forward movement of the carriage bringing with it the hopper and
bracket Y and the co-acting mechanism it will be seen that on account of the
end of the rod 18 being pivotally connected to the plate 15 as hereinbefore
described, such plate will be caused to swing upwardly towards the chute carrying
with it the arm 14, which will pass upwardly through the slot u' and poke out
any button which would have a tendency to stick against the selecting plate Z.
It will be seen that the slot 17 in the arm 13 allows of the free upward movement
of the inner end of the arm in the chute. The means above described it will be
readily understood effectually form an auxiliary means for relieving the upper end
of the chute from an improperly placed button.
The chute U is provided with sides U which have openings or perforations ³,
so as to enable the operator of the machine to see the buttons as they pass down

page_text: through the chute. In order to provide for the adjustment of the sides of the
chute to accommodate and guide centrally the different diameter of buttons I
provide the following simple arrangement, which is clearly shown in Fig. 4.
22 are notches made in each side of the front plate U of the chute. 23 are
plates, which extend through the notches 22. such plates being secured to the
sides U of the chute at the back of the plate U. 24 is the screw spindle, which
extends through the forwardly extending portions of the plates 23, the spindles
being secured from lateral movement by the pin 25 extending between the collars 26
secured to the spindle. One end of the spindle has a right hand thread and the
other a left hand thread. It will, therefore, be readily seen that by turning the
knob of the screw spindle the side plates Us of the chute may be adjustel to or
from each other as desired.
In order to provide for the delivery of the button from the bottom of the chute
to between the receiving chucks opposite the boring spindle I provide the following
mechanism. 27 is an arm, which is secured to the carriage P and extends upwardly
in the form shown. 28 is a table forming part of the lever 28' pivoted near the
lower end and 29 are curved gripping fingers, which are pivoted at 30 uear the arm
upon the top of the plate, so that they may have a lateral movement at the free
end. The curved free ends of the arms 29 are preferably disc-shaped as indicated.
31 is a spindle provided with a knob, which extends through the fingers 29 being
secured to one arm and extending freely through a hole in the other. 32 is a
tension spring, which extends between the fingers 29 and through which the
spindie 31 extends. The spring 32 is attached to both fingers and thu natural
tendency of such spring is to draw the fingers together. 33 is an arm pivoted at
the top of the arm 27 and 34 is a boss on such arm. 35 is a set screw extending
through the upper end of the arm and designed to be brought normally
against the boss 34 by means of the spiral spring 36 connected to the top of the
arm 27 aud to the arm 36. 37 is a pin, which extends laterally through each side
of the arm at the lower end. 38 are disca secured to the inside of each arm, such
dises having preferably substantially conical inner sides.
40 is a rcd pivotally connected to the lever 28. The lever 40 has a threaded
end 40', which extends freely through the collar 41 secured on the upper end of
the standard B. 42 is an adjusting nut, which is screwed on to the threaded
end 40 of the spindle 40 and 43 is a spiral spring, which surrounds the threaded
rod 40 and extends between the inner end of the nut 42 and the collar 41. 44 is
a rod, which extends through the laterally extending upper end s of the lever S.
The end of the rod 44 is threaded and is provided with au adjusting nut 45 as
shown.
The operation of the fingers 29 in delivering the button from the bottom of the
chute between the chucks is as follows.
The fingers 29 are shown in Figs. 1 and 2 in the position after they have gripped
the button. After the button has reached the position shown in dotted lines
against the bottom end of the spring arm and is gripped as shown the cain L
operates on the lever S, rod 44, lever 28', so as to bring down the fingers 29 with
the button in between the ends passed the forked spring plate Y into position
centrally between the chucks, the chuck R of which is now held open. Immediately
this position is reached the cam L would release the rod T and lever Q and allow
the spring g' to close the chuck R and hold the button against the stationary
plate U, which is provided with a hole through which the drills operate. At the
same time the cam L will be pulling through the lever S and rod 44 upon the
lever 28 tilting it in the opposite direction and carrying up with it the fingers 29,
which when the conical busses 38 reach the laterally extending pins 37 on the end
of the arm 33, such fingers 29 will be forced apart momentarily so as to grip the
next deposited button above the forked eud of the spring plate Y'. After the
pins 37 have passed the bosses 38 the spring 32 draws the fugers together and
the button is gripped. When the fingers 29 are again caused to move downwardly
after the button is gripped as hereinbefore described it will be readily seen that

page_text: the conical bosses 38 would slide past the pins 37 extending laterally out from
each side of the arm, the spring 36 allowing of the giving of the arm 33 for such
purpose.
It will thus be seen that I have provided in my attachment a means for gathering
the buttons together successively in their proper relative position to enter the chute
in which they are held one above the other and means for gripping each button as
it passes down beyond the end of the chute and carrying it into position between
the stationary and longitudinal moving chuck. When held between such chucks
of course the boring is done and the finished button is deposited or carried off in
any suitable manner.
