[A communication by WILLIAM ALLEN PENDRY of 910 Chamber of Commerce
Building, Detroit in the County of Wayne and State of Michigan, United
States of America.]
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester both
in the County of Lancaster, 118, New Street, Birmingham in the County of War-
wick, and 322, High Holborn in the County of Middlesex, Civil Engineer, do here-
by 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:
This invention relates to an improved Button Making Machine, having for its
object a machine for this purpose whereby the entire operation of making com-
pleted buttons from suitable blanks may be carried out by a single machine
rabidly and economically, various operations necessary for the construction of the
completed buttons being carried out by the machine in a succession of steps or
stages from the feeding of the button blanks thereto until the finished result is
obtained.
The invention has more especial reference to a machine for making pearl
buttons, but my correspondent would have it understood that he does not confine
its scope or application thereto alone, as it may be used for the construction of
buttons from other materials.
The invention consists of the constructions, combinations and arrangements of
devices and appliances hereinafter specified and claimed, and illustrated in the
accompanying drawings, in which—

This invention is carried out as follows:-
The supporting frame may be of any suitable construction. As shown in the
drawings, it consists of a base A, a spider A-1, a support A-2, a stationary
table A-3, and a stationary race or track A-4, having a connected spider A-5.
A-6 is a suitable enclosing case. A-7 is a top or covering. B is a main driv-
ing shaft provided with a driving pulley B-1. C denotes a shaft provided with a
heveled gear C-1, meshing with a gear B-2 upon the shaft B. C-2 is a non-
rotatable collar located upon the shaft C, in which the driving shaft B is journaled
at one end, as indicated at b, the opposite end of the driving shaft having its bear-
ings upon the base A, as indicated at a. The shaft C is journaled at its lower
end in the base A, and its upper end in the spider A-1, and is provided at its
upper end above said spider with a gear C-3. Upon the stationary table A-3
are supported a feeding device D, a grinder E, a button reversing device F, an
additional grinder G, buffing devices H and H-1, a series of drilling devices I,
an additional buffer J, and, if desired, a counter K.
In the accompanying drawings are shown two buffing devices H and H-1
between the grinder G and the adjacent drilling device, and an additional buffing
device J between the last of the series of drills and the feeding device, but my
correspondent wishes it to be understood that he does not limit himself to any
definite number of buffing devices, as his invention contemplates any desired
number as coming within its scope. So, also, he has shown in the drawings a
series of five drilling devices that number being provided to drill four outer holes
and the centre well, but he would have it understood that he does not limit him-
self to any definite number of drills, since his improved machine is intended to be
furnished with any required number to drill any desired number of holes in the
buttons. The particular construction and operation of these feeding, reversing
and buffing devices, together with that of the grinders and drills, will be herein-
after described.
L denotes a rotatable turret or table carrying a series of chucks M. In Fig. 1,
a series of 12 chucks is shown, but my correspondent would have it understood

page_text: that he does not limit himself to any particular number thereof, as his invention
contemplates the emplovment of any desired number of chucks carried by the
revolving turret or table. The construction and operation of the series of chucks
will be subsequently explained. The turret is preferably constructed with an
outer rim Li and an inner rim L-2, the outer rim being preferably of cylin-
drical form, and the inner rim of angular form, as shown. In these rims the
chucks are supported, the rims being connected by a suitable number of arms 7.
The rim L 1 travels in its rotation upon the race or track A-4 therebeneath.
N denotes a rotatable sleeve or hollow axle provided with a toothed disk N-1
at its lower end, the upper extremity of the sleeve being rigidly engaged with the
turret in any suitable manner. In the drawings the sleeve N is shown constructed
with a flange n at its upper end, which may be secured in any suitable manner
to a corresponding flange -1 upon the inner rim L-2 of the turret. The sleeve
or axle N is actuated by means of a rotatable disk P upon a shaft P-1 geared with
the gear C-3, as by intermediate gears P-2, P-3. The disk N-1 is arranged
to be rotated one step by each complete revolution of the disk P in any suitable
manner. The turret shown in the drawings is provided with 12 chucks M. The
disk N1 is arranged therefore to be rotated one-twelfth of a complete revolution
upon each complete revolution of the disk P. The disk N-1 is accordingly pro-
vided upon its periphery with 12 recesses or notches n--1, as shown in Figures 6
and 20, engaged by a pawl P-4 actuated once upon each complete revolution of
the disk P in any suitable manner, as by a cam P-5 to disengage the pawl from
the disk N-1 while a spur or arm P-6 engages in one of said recesses or notches
and carries the disk N-1 forward one-twelfth of a complete revolution. The pawl
serves to hold the said disk from rotation during the intervals between the stop
movements of the disk. It will be understood that the chucks are spaced one
from another upon the turret a distance apart corresponding to the stop move-
ment of the turret, the various feeding, grinding, reversing, buffing and drilling
devices located upon the stationary table A-3 being spaced one from another in a
similar manner, so that as the turret revolves, the chucks will be moved by succes-
sive steps from one to another of said devices upon said table to present the button
blanks, being carried by the chucks to said device, in successive order until the
button is completed.
The shaft B is provided with a pulley B-3 for driving the feeding mechanism.
Meshing with the beveled gear C-1, is a series of gears for driving the grinding,
buffing and drilling mechanisnis. Thus to drive the grinder E, a gear E-1 upon
a shaft E-2 meshing with the gear C-1 is provided. E-3 is a pulley belted
with a suitable part of said grinder, said pulley being located upon a shaft E-4
geared with the shaft E-2 by intermediate gears e, e-1.
The grinder G is similarly driven by a beveled gear G-1 upon a shaft G-2
geared to a shaft G-3, as by gears 9, 9-1, the shaft G--3 being provided with a
pulley G-4.
Similar driving mechanism is provided to drive the buffers H and H—1. As
indicated in the drawings, H-2 and H-3 are shafts provided with gears H-4
and H-5, respectively, meshing with the gear C-1 and with shafts H-6 and
H-7, as by intermediate gears h, h-1, said shafts each being provided with a
pulley H-8. To drive the several drills, the gears I-1 are provided, located
upon shafts I-2, respectively, and meshing with the gear C-1, said shafts being
provided with driving pulleys I-3, respectively, belted with corresponding parts
of the drilling mechanism. The buffer J is driven by a similar mechanism, in-
dicated in general at J-1, the driving mechanism being the duplicate of that
already explained for driving the buffers H and H-1 and the grinder G. The
shafts E—2, G—2, H-2, H3, and J-1 are further provided with pulleys, in-
dicated by the numerals 1, 2, 3, 4, 5, for driving the chucks M, as hereinafter
5 explained. Within the hollow axle N is a stationary cylindrical casting Q, pro-
vided with flanges 9, 9-1 at its upper end above the flange n of the axle N, the
Within the cylindrical casting Q is located a
flange q resting upon the flange n.

page_text: vertical guide Q-1, having guide arms, indicated by the numerals 6 and 8, ver-
tically recessed, as shown, in each of which arms is located a corresponding
vertically movable slide 9 provided with beveled faced shoulders 10 and 11. These
slides are actuated from a rotatable shaft R geared to the shaft P-1, as by inter-
mediate gears r and p. The shafts P-1 and R are journaled in the spider A-1
and support A-2, as shown. Upon the shaft R are engaged eccentrics R-1
connected by rods R-2 to bell cranks R-3 connected with the slides 9, respec-
tively, and by which said slides are reciprocated, one of the rods R-2 being shown
broken off in Figure 2.
The construction of one of the chucks M, shown in detail in Figure 15 will next
be described.
All the chucks of the series are preferably of similar construction. These chucks
are located upon the rims L--1, L-2 of the turret, said rims being provided with
bearings L-3 and L-4 for each of the chucks. L-5 is a bushing in the bear-
ing L-3, preferably having a threaded engagement therewith, as shown.
M-1 denotes a hollow shaft, having a reciprocatory and rotatable engagement
in said bearings and provided with a pulley M-2, preferably secured to said shaft
by a screw 2. Within said shaft is a sleeve M-3, with one end of which is
engaged a clamping device M-4, which may be made tubular at the inner end
and having a screw threaded engagement with the sleeve M-3, as shown. The
outer extremity of the clamping device is divided into a series of clamping jaws m,
as indicated more fully in Figure 19. Said jaws are made normally flaring and
constructed with inwardly turned fingers m-1 at their extremities to grasp the
periphery of a button blank. The sleeve M-3 and the clamping device M--
are non-reciprocatory, one end of the sleeve being provided with a flange m-2,
over which the bushing L-5 is engaged to hold it longitudinally immovable.
Within the sleeve M-3 is a spindle M-5, provided at one end with a head m—3,
preferably removable, as shown, so as to be interchangeable for different sizes of
buttons. This head is sufficiently large to form a support for the back of the button,
so that the drills, in passing through the button blank, will not chip away or break
out the back, as the chipping or breaking away of the back damages the button and
reduces its value. The button blank indicated at m-4 is held against said head
by the jaws m. The spindle M-5 has a reciprocatory movement within the
sleeve M-3 and the clamping device M-4, and is also made to rotate with the
sleeve. In Fig. 15 a screw 1-5 is shown engaging the sleeve and the spindle to 3
cause their simultaneous rotation. The shaft M-1 is made to reciprocate by any
suitable device and it is moved toward the head of the spindle M-5, it causes
the jaws m to be pressed against the periphery of the button blank to hold the
blank firmly in place. The opposite movement of the shaft will remove the
pressure upon said jaws. The forward reciprocation of the spindle M-5 will
force the button blank out of engagement with the jaws. M-6 is a cap engaged
upon the outer end of the shaft M-1 and the bearing L-4. The shaft M-1 is
shown in the drawings to be reciprocated in the following manner:—
M-7 denotes a yoke engaging the shaft M-1, said yoke being carried by a
slide m-5, with which is engaged a spindle m-6, upon which is mounted a 4
coiled spring m-7. The rear end of the spindle m-6 projects inward adjacent
to the beveled faced shoulder 11 of the slide 9, whereby said spindle is moved for-
ward when the slide 9 is moved downward, carrying with it the slide m-5, the
yoke M-7 and the shaft M-1.
The rims L-1, L-2 may be provided with any suitable guides for said 5
slide m-5, as indicated at m--8, Figure 16. The spindle M-5 may also be
reciprocated in any desired manner. As shown, the flange 7 of the cylindrical
casting is provided with reciprocatory shafts q-2 arranged to bear upon the
inner ends of the spindles M-5 when they arrive in the proper position as the
turret is rotated step by step. The inner ends of said shaft q-2 extend adjacent 5
to the shoulders 10 of the slide 9 whereby said shafts are actuated upon a proper

page_text: movement of the slide 9, thereby forcing outward the corresponding spindle M--5
which is provided with a retracting spring m-9. Spring m-7 allows the
slide m 5 to yield in case undue pressure is brought to bear upon the shaft M-I
and consequently upon the button blank. The spindles m-6, it will be observed,
are moved forward to cause the jaws m to grip the button on the descent of the
slide 9, while the spindle M-3 is moved forward to release the button on the
upward movement of the slide 9.
The pulleys M-2 may be rotated in any desired manner within the scope of
this invention. As shown, they may be rotated by frictional contact with
belts M-8, said belts being engaged respectively with the pulleys 1, 2, 3, 4, 5, on
shafts E-2, G-2, H-2, H-3 and J-1, and over pulleys 12, 13, 14, 15 and 16
upon corresponding journals attached to the track At. It will be evident how-
ever, that when the button blanks are being drilled the chucks will need to be
stationary. This may be done in any desired manner. As shown, it is accom-
plished by means of pawls M-9 fulcrumed upon the rim L-1 and engaging with
notches m-10 in the periphery or numbering plate M-10 of the corresponding
pulley M-2. The opposite end of the said pawl extends downward in the path
of a trip 17 as the turret is rotated, the trip serving to lift the pawl out of engage-
ment with the corresponding pulley M-2, permitting its rotation to another notch.
This rotation may be accomplished by a wiper 18 upon the upper edge of which
the periphery of the pulley M-2 travels and by which said pulley M-2 is rotated
as the turret revolves step by step. The trips and wipers 17 and 18 are located
toward the base of the rim L-1 and may be secured in place in any suitable man-
ner. In Fig. 16 they are shown bolted to one of the arms of the spider A-5.
In Fig. 4 the trips 17 are shown elongated opposite the pulleys 12 and 13 sufficient
to hold the pawl out of engagement with the pulley M-2 while a chuck is opposite
the buffer mechanism J, and the grinder E. The trip is further elongated as
shown in Fig. 4 adjacent to the pulleys 14, 15, 16, sufficiently to hold said pawl out
of engagement with the corresponding pulley M-2 while the chuck is opposite
the grinder G and the buffers H, H-1. Adjacent to the drilling devices, the
trips 17 are made shorter so that the pulley M-2 will be held from rotation while
opposite the respective drills, a shortened form of the trip is shown in Fig. 14.
The construction of the feeding device 1 shown in detail more particularly. in
Figs. 7, 8 and 9 will next be described. The device here shown consists in a
rotatable feed wheel D-1 constructed with a series of orifices d on its periphery
into which orifices the button blanks are placed by an attendant. This disk is
rotated by a gear D-2 meshing with a gear D3 supported upon a sliding
bracket 31. Within the wheel D-1 are located a series of spring actuated
spindles d-1 corresponding to the number of orifices d, the outer extremities of
said spindles being adjacent to said orifices.
Fulcrumed on the shaft 2 of the gear 1-3 is a vibratory lever D-4 pro-
vided with a spring actuated pawl d-3 at one extremity thereof engaging the
toothed periphery of the gear 1-3. With the opposite end of the lever D-4 is
connected a reciprocatory rod d-4 which upon being raised will obviously cause
the pawl 3 to rotate the gear 1-3 one step thereby actuating the gear D-2
and the disk D-1 in a corresponding manner one step, the distance travelled by
successive steps of the disk D-1 being sufficient to carry the orifices done by
one in succession around in front of the adjacent chuck M and in position to
deliver a button blank to the jaws of the chuck.
As already described, the main driving shaft B is provided with a pulley B-3
for driving the feeding mechanism, a sprocket belt 19 leading therefrom to a
sprocket wheel 20 upon a shaft 21 having its bearings in hangers 22. Upon said
shaft 21 is engaged a double cam 23 having a cam-shaped periphery and also a
cam groove 24. A vibratory arm 25 is provided at its lower end with a pin 27
engaged in the cam groove 24, the rotation of the cam serving to vibrate said arm.
The upper and lower portions 25 and 26 of said arm are fulcrumed intermediate

page_text: their extremities as shown at 28. The upper
end of the portion 26 of said arm is
constructed with a finger or flange 29 projecting into the centre of the wheel D-1
between the inner ends of the spindles d—1.
A retracting spring 30 connects the arm 25-26 to a sliding carriage 31, said
carriage carrying the feed wheel D-1 and gears D-2, D-3, and being arranged
to slide in an opening 32 in a stationary bracket 33 on the table A-3. When the
arm 25-26 is actuated it will first pull on the spring 30 thereby advancing the
carriage 31 and the feed wheel to the chuck." When the feed wheel
meets the chuck its further advancement is checked, but the further
movement of the arm 25-26 carries the flange 29 to strike against
the adjacent end of the spindle din its path to force said spindle
outward and thereby push the button blank in the corresponding orifice d
into the jaws of the adjacent chuck. On the opposite movement of the arm 25-26
it strikes against a stud d- to force backward the carriage 31. An upward
movement is given to the rod d-4 by bringing its lower extremity down to engage
a rocking-step D-5 fulcrumed as at d, upon a bracket D-6, said steps riding
upon the periphery of the cam 23.
The construction of one of the buffing devices H, H-1 and J, shown in detail
in Figs. 17 and 18 will next be described. These buffing devices and the
grinders E and G may all be constructed essentially alike, the single description
of the device shown in Figs. 17 and 18 will answer as a description for them all.
Accordingly, 34 denotes a shaft supported in the bearings 35 and 36, the shaft
being provided with a pulley 37 belted as by a belt 38 with a corresponding
pulley 39, the shaft of which is belted as by a belt 41 with the corresponding
pulleys H-8, E3, C4, or J-2 geared with the shaft J-1 as the case may be.
Upon one end of the shaft 34 is a buffing wheel 42. A suitable grinder 43 takes
the place of the buffing wheel in the grinding devices E and C. This grinder is
preferably made of emery or analogous grinding or abrading material. In order
to move the buffing wheels or grinders inward against the base of the button blanks,
in order that the buffing wheel and grinders may operate upon said blanks, the
bearings 35 and 36 are mounted upon a slide 44 with which is connected a bell
crank 45 which may be fulcrumed to the table A-, one arm, as the arm 46, being
conrecteil with the corresponding slide as by an upright bracket 47, and the other
arm is connected with a proper source of power to operate said crank as shown in
Fig. The arms 48 of said bell cranks are all connected together as by rods 49
so as to be simultaneously actuated. The means of actuating said bell cranks will
be described hereafter. The bracket 47 is bolted to the horizontal portion of the
slide 44 and adjustably connected also with vertical flange 50 of said slide as by
a bolt 51 having a threaded engagement with said bracket for adjusting the operation
of the slide.
The feeding, buffing and grinding mechanisms of the machine being now
described, the construction of the button reversing mechanism F as herewith shown
more particularly in detail in Figs. 23, 24 and 25, will next be explained in
which indicates a housing located upon the table A-3 and supporting a
sliding bed -2 in which is mounted a horizontally reciprocatory spindle F-3
and an upright partially rotatable spindle F-4 carrying at its upper end a ring f
to receive the button blank from the corresponding chuck. The orifice through
said ring, it will be perceived, is in the line of reciprocation of the spindle F-3.
The upper end of the spindle F-1 carrying the ring f is preferably made detach-
able, as indicated at f—1, to permit the interchanging of said ring for different
sizes of button blanks. A set screw f-2 shown in Fig. 30 serves to hold the said
spindle in place within a bushing f-3. Upon the lower end of the spindle F-4
is a gear meshing with a gear 1-5 upon a shaft F-6. F-7 is a shaft
carrying at its upper end a crank arm -5 engaging one extremity of the
spindle 3 to reciprocate said spindle.
The purpose of this reversing mechanism is to take a button blank m 4 from
an adjacent chuck M, the blank being received into the ring f, the end of the

page_text: spindle F3 being advanced partially into said ring sufficiently to form a backing
for the blank as it is so received into the ring, then to turn the ring about one-half
of a revolution and then to force the blank back into the chuck by another advance-
ment of the spindle F-3, said spindle retracting after its first advancement
partially into the ring in order to permit the turning of the ring to present the
opposite face of the blank to the chuck. The slide F-2 is to be advanced to the
chuck. the ring f advancing over the periphery of the blank as the clamping
jaws m-6 are released therefrom. It will be observed by reference to Fig. 15,
that the button blanks, projects outward from the jaws sufficiently to permit the
ring to advance partially over its periphery. The first advancement of the
spindle F-3 partially into the ring is necessary to hold the blank in proper upright
position. The movements of the parts now described to accomplish this reversing
of the blank are accomplished as follows:-
In Figs. 10 and 24, S denotes a gear journalled upon the spider A-1 geared with
the gear C-3 upon the shaft C bv intermediate gears S-1 and S-2. The gear S
is mounted upon a shaft S-3 upon which is engaged a cam 52, a cam 53, and a
cam 54. F-8 is a star-shaped gear upon the lower end of the shaft F-6.
slide 1 is engaged with the under face of the table A-3 which slide is connected
by an arm a-2 with the shaft F-7.
A
One extremity of this slide is provided with a spur a-3 riding upon the periphery
of the cam 54, whereby reciprocatory movement is given to the spindle F—3.
155 is a bell crank. lever fulcrumed to the table A-3 as at 50-1, having at one
end thereof a spur 57-1 riding on the periphery of the cam 53, and at the opposite
end with a spur 57-2. An arm 56 is engaged with a shaft 57 leading up to an arm
58 connected with a slide 2, the arm 56 being provided with a spur 59 con-
tacting with the periphery of the cam 52. The spurs in the ends of the levers may
be kept in contact with their respective cams in any suitable manner, as by
springs 52 shown in Fig. 31. It will be seen that as the shaft S-3 is rotated, the
cain 52 actuating the arm 56 will move the slide F-2 accordingly, the slide
carrying with it the shaft F-6 of the star-shaped gear F-8. The backward
movement of the shaft F-6 will cause the star-shaped gear F-8 to contact with
the spur 572 on the bell crank 55 whereby said gear will be partially rotated,
rotating the gear F-5 in a corresponding manner but not sufficiently to causo
the proper rotation of the shaft F-4 for reversing the button blank. The move-
ment of the cam 53, however, operating upon the bell crank 55, will give it a throw
to further rotate the star-shaped gear and thereby give a further rotation to the
shaft F6 to complete the proper movement of the gear F5 which should have
a quarter revolution, giving a half a revolution to the gear f-4 thereby reversing
the button blank. The cam 54 is provided with a short and with a long tooth.as
indicated. The riding of the spur a-3 over the short tooth will force the
spindle F-3 partially into the ring f to form a backing for the button blank when
the ring fis advanced to the chuck. The spindle F-3 is then retracted while
said ring is reversed, but it is again advanced a still further distance as a spur a--3
rides over the longer tooth to force the blank into the chuck again.
The construction of one of the series of drills I will now be explained, the series
of drills being all of the same 'construction, so that a description of one of them
answers for all, as shown more particularly in Figs. 2, 11-14, 21, 20, 27 and 28.
A-S denotes a bracket engaged on the under face of a housing I-4 in which
is journaled a driving shaft A-9 provided with a gear a-4 meshing with a
gear A-10 as upon the axle N by which the said shaft is driven said shaft being
journaled toward the bevel gear a 4 in the bracket 60, a series of said brackets
being united to a plate 61. At the opposite end the shaft A-9 is provided with
a gear a-5.
Within the housing I-4 is located a rotatable spool I-5 toothed at one end to
mesh with a gear a-6 as shown. In this spool are journalled tubular spindles I-6
and I-7.each provided with a driving pulley I-8. Within each of said spindles
is a sleeve I-9 carrying a drill I-10. The spindles I-6. I-7 are rotated by

page_text: means of a bell 62 passed over the pulley I-8. The inner ends of said spindles
are formed with jaws i, as shown in Fig. 26, and 63 denotes a cap having a screw
theaded engagement upon each of said spindles to clamp said jaws upon the drill
1-10. The opposite extremities of the sleeves I-9 are connected by a cross
arm 64, said sleeves being arranged to be advanced simultaneously into the corre-
sponding tubular spindles. 65 is a threaded spindle engaged with said cross arm
intermediate the ends thereof, as shown at 66. The spool I-5 is constructed with
a central orifice indicated at 67, into one end of which is engaged an interiorly
threaded hub 68 provided with a ratchet disk 69. 70 denotes an additional ratchet
keyed as indicated at 71 into a key-way 72 on the spindle 65. Between the
ratchets 69 and 70 is located a plate 73 provided with an arm 74, a spring 75 con-
necting said arm with the spool I-5. The plate at its opposite end is provided
with a spur 1 engaged with a lever arm 76 fulcrumed intermediate its ends to
the spool I-5. Upon the housing I-4 is a trip -2 so located that at each
revolution of the spool said lever arm 76 will strike the trip thereby tilting the
plate 73. 77 and 78 are pawls supported upon said plate and engaging said ratchets.
it will be perceived that whenever the plate 73 is thrown downward by the move-
ment of the lever arm 76 as above specified, the pawls will exert a pull upon their
respective ratchet wheels. In order to give a suitable speed in the travel of the
drills I-10, one of said ratchet wheels, as the ratchet 69, is constructed with mora
teeth than the ratchet 70, as will be seen by comparing Figs. 27 and 28. It will
be obvious that if the ratchets 69 and 70 had an equal number of teeth, the
spindle 65 would not be advanced. But by making the ratchet 69 with more teeth
as above explained, said spindle will be correspondingly advanced slowly, but not
too fast, to the work, as would be the case were the two ratchets not constructed and
operating as above set forth. The hub 69 is secured to the spool I-5 by means
of a yoke T, shown in Figs. 11 and 34, particularly screws t t connecting the yoke
to the spool.
The drill rods I-10 are not clamped so tightly by the caps 63 as to prevent the
longitudinal movement of the drill rods, said caps being designed to close the
orifice within the jaws through which the needle rods project, so that there may be
a close fit of the jaws upon varying sizes of drill rods, or rods of varying gauges.
It will be understood that the sleeves I-6 are not longitudinally movable.
The hub 68 is interiorly threaded to receive the spindle 65. If said hub was
rotated by the ratchet wheel 69, having the same number of teeth as the ratchet :
wheel 70, there could not be any motion of the spindle longitudinally, but if the
number of teeth on the ratchet 69 differs from the number of teeth on the ratchet 70,
the rotation of the hub will be less than the rotation of the spindle 65. Hence the
longitudinal movement of the spindle would correspond to the difference of rotation
of the hub 68 and ratchet 70.
Two spindles I-6, I—7, with their sleeves I-9 and drills I-10, are employed
su that the one drill may be sharpened while the the other is at work. To this end,
the sol I-5 is made rotatable by means of the gear a-6 bringing each drill
alternately in posititon to do its work while the other drill is being sharpened. A
suitable grinding wheel is shown at 79 for sharpening the drills, one of said wheels
being adjacent to cach drilling device I, each wheel being mounted upon a shaft 80
provided with a driving pulley S1. The driving pulleys 81 of the several sets of
drills I may all be operated by a single belt 82, shown in Figure 4 more particularly,
running over said pulleys 81, and over additional pulleys 83 secured upon the
table 3, thence over a pulley 85 and downward under a pulley S6, thence up over
a pulley 87 and under a pulley S8, thence up over a pulley 81 and over the
pulleys S, or vice versa as may be desired to give the right direction of movement
to the grinding wheels.
In order that the grinding wheels may do their work properly, it will be desirable
to give them a vertical agitation, which is accomplished by means of a lever 89 5
engaged to a spur - upon the shaft 80, said lever fulcrumed intermediate its
ends as at -1, the lever being connected by a rod 90 to an eccentric 91 upon a

page_text: corresponding shaft I-2. It will be apparent that since a step by step movement
is given to the turret by its driving mechanism as hereinbefore described, a similar
step by step movement will be given to the gear A-10 and consequently, to the
gears which rotate the spools I-5 of the several drilling devices.
In the particular machine shown in the drawings, it will be remembered
12 chucks are provided, the disk N-1 being correspondingly constructed with
12 peripheral recesses n-1, said disk being locked at each step by the pawl P-4.
In a corresponding manner the gear A-10 is constructed with 12 times the number
of teeth on the gear a-4, so that one-twelfth of a complete rotation of the
gear A-10 or one step movement thereof will give to the gear a-4 a complete
revolution. The gear a-5 should be constructed with one-half the number of teeth
that are upon the spool I-5, thereby causing the spool to make one-half of a com-
plete revolution at each step of the turret, thus exactly reversing the position of
the two drills I-10 at each step movement of the turret to bring said drills alter-
nately to the corresponding grinding wheel 79. To bring the several spools with
their drilling mechanisms up to the work, said spools have a longitudinal movement
upon the table A-3 To effect the movement of the drills the spools 1-5 are
each constructed with a circumferential groove -5 in which is engaged
one extremity of a slide 92 connected with the bearing 93 of the shaft of the
corresponding grinding wheel. At the opposite end said slide is engaged with a
bell crank lever 94, the bell cranks being connected by rods 95. One of the bell
cranks 94 is constructed with an arm 96 riding upon a cam or eccentric 97 upon a
shaft 98 by which proper movement is given to the slides 92 to reciprocate the
corresponding spools I-5 to bring the drills to and from the work. It will thus
be perceived that not only the turret but all the mechanisms thereupon and there-
about are governed in their step by step movements by the locking pawl P-4
engageable with the disk N-1.
The various shafts 40 upon which are engaged the pulleys for the belts 38 and 41
have their bearings upon arms 99 and the adiacent arms of the spider A-1, it
being understood that there is a set of said pulleys for each of the grinders E, G
and each of the buffing devices II, H-1 and J, similar to those shown in Figs. 2
and 10.
To release the completed button from its chuck after it has passed the
buffing device J, one of the shafts 7-2 is constructed with a lateral arm 7-3
indicated in dotted lines in Fig. 1 upon which the spindle M-5 of the chuck
rides before it reaches its primary position before the feeder 1. thereby opening
the jaws of the chuck as hereinbefore described, the jaws being held open until the
next button blank is received there into in the manner herein before specified.
The feeder D, the grinding devices, one or more, the buffing devices, one or more,
are the operative devices, together with the reversing device F to the work upon a
button blank, the chucks M serving to carry the blanks to said operative devices
in proper succession. Should it not be desired to finish both faces of the button,
the reversing device might be omitted.
The operation of the machine will now be understood. The attendant puts the
button blanks into the feeding device D from which the blanks are passed into the
adjacent chuck M. As the turret revolves that given chuck carries its button
blank upon the first step movement of the turret to the grinder E by which one
face of the blank is ground. The next step movement of the turret carries said
chuck to the reversing mechanism whereby the blank is reversed. The next step
movement of the turret carries the chuck to the grinder G by which the opposite
face of the blank is ground.
Then successive steps of the turret, the chuck carries the blank to the buffers H
nd H-1, then step by step to the several drills I, thence past the counter K which
may be of any desired construction, not specifically described herewith, thence to
he final buffer J, passing which, the said chuck discharges the completed button
nto a chute 100. That individual chuck is then ready to receive another button

page_text: blank. Meanwhile, of course, in the progress of the chuck with the turret as
already described, other succeeding chucks are following the same course in succes-
sion all carrying their respective button blanks to the grinding reversing, buffing,
and drilling devices, as described, the button blanks passing only once through the
hands of the attendant whose only duty is to feed the blanks to the feeding
device D.
Obviously the buttons may be completed in this manner, rapidly and
economically.
The reciprocatory spindle and plunger F-3 is provided with a movable
head f-6 so that the head may be interchanged to correspond with the changing of
the ring f. The ring f is preferably split, as shown more particularly in Fig. 29,
so as to exert a spring tension upon the periphery of a button blank to hold the
blank securely therewithin.
The ring is also preferably constructed with beveled front and rear edges, as
indicated in Fig. 30 so that the rings may the more conveniently and surely engage
the periphery of the button blank.
The housing I-4 of each of the series of drills I, is preferably made adjustable
on the table A-3. To this end, the housings are each mounted upon a base
plate A-11 open at the centre, as shown, provided with elongated slots a-7 where-
by the plate may be adjusted and held in a longitudinal plane by means of
bolts a 8. By this means, the drill rods I-10 may be caused to bore the button
blanks at any desired angle. The first drilling device in the series is preferably
constructed to form the well" of the button.
The buffing device J, if employed, serves as a wiper to clean the completed button
from the cuttings and dust of the drills.
The shaft A-9, Fig. 14, is provided with a joint, as indicated at a-9 to permit
the drilling device to be set at a desired angle to the work as above described.
The winers 18 are designed to be of a length suflicient to cause a quarter rotation
of the corresponding chuck at each step of the turret adjacent to the last four drills,
so as to bring the button blank into proper position for the respective holes.
As already described, the belts over the pulleys 12, 13, 14, 15, 16 cause the
chucks to rotate opposite the grinding and buffing devices.
My correspondent would have it understood that he does not limit himself solely
to all the specific details of construction, herein shown and described.
While special constructions of the feeding mechanism, grinders, buffers, and other
operative devices to work on the button blank are shown, it is to be definitely
understood that the invention is not limited especially to the construction shown,
nor to any definite number of them, as it contemplates the employment of any
suitable operative devices to work upon the button blank to cut, polish and drill
said blanks presented thereto in successive steps in a single machine.
To drill a less number of holes than those provided for in the machine herewith
shown and described. a desired number of the drills may be thrown out of operation
in any desired manner.
The interchangeable drills are each held adjacent to the grinding wheel in a
fixed or non-rotatable position, the upper drill only being rotatable on its axes.
It will be perceived by reference to Fig. 11 that the belt 62 is out of contact with
the pulley on the lower spindle. To hold each lower spindle in fixed or non-
1otatable position while its drill rod is being ground, any suitable device may be
employed, as for example, a pawl T-2, indicated in dotted lines in Fig. 11,
arranged to enter a suitable recess at -1 in the pulley on the lower spindle when
the pulley has reached the proper position, the pawl locking the lower spindie
adjacent to the grinding wheel. A stationary wiper T-3, indicated in dotted liues
in Fig. 11, releases the pawl from the corresponding pulley when the pulleys
change positions.
The carrying device or spool I-5 is arranged to be locked in alternately reverse:
position. As shown in Fig. 14 of the drawings this is accomplished by means of
a tapered key -8 attached to the housing I-4, the said spool being constructed

page_text: with a corresponding socket, indicated at i-9, to slip over the key as the spool is
advanced.
