COMPLETE SPECIFICATION.
An Improved Machine for Making Screws, Bolts, Nipples, Caps,
Nuts, and the like.
I, GEORGE BARKER, Fellow of the Chartered Institute of Patent Agents, of
77 Colmore Row, Birmingham, in the County of Warwick, Consulting Engineer,
do hereby declare the nature of my said invention as communicated to me from
abroad by The Sterling Cycle Works, a Company organized under the Laws of
the State of Illinois, having its business address at 274 Wabash Avenue, Chicago,
Illinois, U.S.A. and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
In the construction or manufacture of various machines, devices and apparatus,
it is necessary to use a number of parts or pieces, usually rather small in size,
which require one or more operations to be performed on them to give the
particular shape, form or characteristic desired. For instance, such parts as
screws, bolts, nipples, caps, nuts and the like, require threading, drilling, slotting
or treatment in some other way well known to skilled machinists, to change the
original castings or blanks to the form or shape they are to have in order to be
available for use.
To machinery for thus making or forming such parts or pieces the invention
relates particularly. It will be readily seen, however, that the principles of
operation and construction which it embodies, need not be limited to any particular
class or size of work, but are applicable to many varieties, irrespective of the
material of which it is composed, the shape or form in which it comes to the
machine, or the number or kind of the operations which are to be performed
on it.
Prominent objects of the invention are to produce a machine which is capable
of automatically performing the various operations incident to the formation of
any particular part or piece-that is to say, a machine which is capable of
receiving stock in a certain condition, of performing on such stock a number
of operations of a predetermined character, and of discharging the finished
product when the last operation has been completed, without requiring manual
assistance from the time the stock enters the machine till the product emerges
therefrom; and to make such a machine capable of efficiently and economically
making such parts with great rapidity, so that large numbers of them may be
turned out in a comparatively short space of time.
A further object of the invention is to provide a machine of this kind which is
particularly adapted for making nipples, caps or attachments for securing the
spokes of bicycle or similar wheels to their rims.
To such end the invention consists in the general arrangement and mode of
operation of such a machine as is hereinafter described; and also in the particular
construction which adapts it for the formation of nipples or caps for bicycle
spokes, from prepared stock in the form of wire.
Hence the description of the invention will be confined to its adaptation to a
machine for making nipples, although, as already stated, it is not intended by so
doing to limit its scope to this particular class of articles.
It will be horne in mind that a nipple of the kind commonly used in the
construction of metal rimmed wheels is provided with an enlarged portion or
head at one end to prevent its being drawn entirely through the rim; and also
with a threaded socket in which the spoke may be inserted and held. The head

page_text: is slotted so that the nipple may be readily turned by a screw-driver when
assembling the various parts of the wheels, and the nipple itself is provided with
flat surfaces, forming substantially a bolt, which may be grasped by a wrench so
as to turn the nipple and thereby tighten the spoke, in case it is inconvenient to
turn the same by a screw-driver, as, for instance, when a tire has been placed on
the rim so as to cover the head of the nipple. Ordinarily the socket of the
nipple extends through its entire length, but only a portion thereof is threaded,
namely, that portion which is at the headed end. The remaining portion is drilled
slightly greater in diameter, so that the end of the spoke may pass through it
freely to engage with the threaded portion. The end of the nipple overlapping
the spoke is also beveled, rounded or tapered, so as to avoid rough, cutting
corners.
To construct a nipple with these characteristics the invention contemplates
assembling in a serial order, various mechanisms for performing the necessary
operations; in providing means for feeding stock wire to the machine and for
cutting it off so as to leave in the machine a portion of the stock wire, constituting
a blank, containing sufficient material for a nipple; and in providing means for
carrying this blank to the various mechanisms, and leaving it in positions to be
successively operated on by them until transformed to a finished nipple. When
thus completed the nipple is automatically discharged or extracted from the
carrying device, and stock for a new blank inserted.
As a preferred construction, the operating mechanisms are mounted on or about
a frame or support forming a tool holder. These consist-in the order in which
the blank is brought to them-in mechanisms, 1st, for upsetting an end of the
stock to form the head; 2nd, for coning or tapering the opposite end of the
nipple; 3rd, for drilling the entering socket; 4th, for drilling a concentric
smaller socket, which is to be threaded; 5th, for threading this smaller socket;
6th for slotting the head to accommodate a screw-driver, and for flattening at the
same time, a portion of the length of the nipple so as to produce faces which may
be grasped by a wrench, which operation we shall term slabbing; and 7th, for
extracting the completed nipple from the carrying device. In order to transport
the blank from one of these mechanisms to another, a carrier, consisting preferably
in a plate or disk is mounted near said tool holder and provided with apertures
wherein the stock wire forming the blanks may be fed and held during the
performance of said operations. This carrying plate is also so arranged that it is
turned a portion of a revolution after stock has been fed in and cut off, to carry
the blank to the first operating tool or mechanism, where it is left until such.
operation has been performed. Then it is turned so as to bring the blank to the
next tool where the second operation is performed; and so on until all the
operations have been performed and the nipple extracted from the aperture
containing it. It will be understood that for economical purposes said carrying
plate or disk is provided with the saine number of apertures as there are
operations to be performed; that such apertures and mechanisms are arranged at
equal distances a part on the circumference of a circle; that wire is fed into an
aperture and cut off so as to leave a blank in the disk at every stop, so that the
disk, after one revolution, contains in its apertures, nipples in all stages of com-
pletion; and that while each individual nipple is operated on serially, all the
nipples in the disk, by being left opposite the various mechanisms at the same
time, are in position to be operated on simultaneously.
Hence, as a matter of further improvement the various operating tools are
arranged so that they perform their respective operations synchronously. As a
preferred means of accomplishing this, the operating mechanisins are slidingly
mounted about the tool holder, which is desirably in the form of a drum and
simultaneously moved toward the blanks left opposite them, rather than have the
carrier with its blanks moved toward said mechanisms which obviously would
accomplish the same result.
It is understood that certain of these tools, such as drills, taps and the like,

page_text: are continually rotating, so that it is only necessary to bring them into contate
with the blanks to secure the performance of their respective operations.
As a simple means of removing the completed nipples from the carrier, a punch
or pin is provided which is arranged to enter the aperture containing such a
nipple, and drive the latter therefrom.
Means are also desirably provided for temporarily locking the carrier at a time
when it is at rest, and when the mechanisms are operating on its contained
blanks. This locking device desirably takes effect just before the mechanisms
operate, and does not release the carrier until after the tools have ceased
operating. By this arrangement, the accurate adjustment of the blanks to the
mechanisms, and their retention in such adjustinent, is insured.
Further novel features of our invention are hereinafter pointed out.

may
In the machine shown the base or frame A serves as a support for the tool
head B and the various operating parts. In front of this drum or tool head B, on
a concentric extension B' thereof, is mounted the carrying plate C (Figs. 3 and 11),
where it is held by the nut C₁ in such a manner that it is free to rotate. This
plate, as aforesaid, is provided with apertures into which the stock wire be
fed and retained in the form of blanks during the transformation of the same into
a nipple. As a preferred construction however, the plate is not apertured to
contain the wire itself, but is constructed, to hold a number of dies D (Fige. 11 & 14)
of hard material, as steel, in which the wire fits snugly. Consequently the con-
tinued wear of the wire on the edges of the apertures or an imperfection either
in material or operation causing the nipple to stick in its aperture does not require
the removal of the carrying plate, but only of so many of the dies as have become
useless.
The wire may be fed to the dies of this plate at any convenient point, and the

page_text: operating mechanisms located to harmonize with the views of the designer. We
have found the following arrangement, however, very advantageous, and shall
describe our machine as so constructed, although the exact relative order of the
operating mechanisms is not regarded as an essential feature of the invention.
Referring to Fig. 1, the wire is fed into a die when it reaches the lower left
hand position marked 1, and while in such position the wire is cut, leaving a blank
inserted in the die. The plate then noves in a direction indicated by the arrow
and is stopped at 2, where the blank is headed. Continuing its motion, it is bevelled
or coned at 4; drilled at 5; drilled again at 6; threaded at 7; slotted and slabbed
at 8; and extracted at 9. At 10 the gauge pin is inserted into one of the
apertures E opposite it at that time, whereby the plate is held to secure the more
accurate and certain adjustment of the plate during the operation of the tools.
It will be noticed that at 3 no function is performed. A place is left here for
any additional operation which may hereafter be considered desirable.
The feeding aud cutting mechanisms are shown in Figs. 4 to 7. The wire,
coming from a reel is straightened horizontally by rollers 12, 13, and 14, and
vertically by rollers 15, 16 and 17, mounted on the arm F. A suitable length is
then fed iuto a die by the wheels 18 and 19, which are intermittently driven by the
crank 20 and pitman 21. This crank 20, is attached to an auxiliary shaft 37 and
the pitman 21 swings arm 22, to which is secured pawl 23 driving ratchet wheel 24,
mounted on the same shaft 25, which carries the wheel 19. Shafts 25 and 26 are
geared together by spurs 27 and 28, so that they rotate in unison.
By this
arrangement, a length of wire G (Fig. 6) suitable for a blank, is fed into the die
by the partial rotation given wheel 18 and 19 by the ratchet wheel 24 and its
pawl 23, beld in engagement by the coil spring 29.
It is desirable to have the wheels 18 and 19 adjustable toward and away from
each other, so that in case the wire tends to slip between them during their
rotation they may be brought nearer together to grip it more tightly. As a
preferred construction the shafts 25 and 26 are eccentrically journaled in the
boxes 30 and 31, which are free to turn in the pillow block 32 (Figs. 6 and 7);
and said boxes are provided with end flanges having peripheral sockets or inden-
tations 34. Hence, if wheels 18, ami 19 permit the wire to slip between them
they may be brought nearer together by lifting the latch spring 33, so as to
disengage its knob 34 from the socket it then occupies, and then turning one or
both of said boxes 30 and 31 until slippage is prevented.
When a length of the stock wire has thus been fed into a die, it is necessary
to sever the same by a suitable cutting device. For this purpose a saw 36 is
employed, whose shaft 38 (Figs. 4 and 5) is carried by the rocker arms 39,
mounted on the rock shaft 40. Secured also to this shaft is the dog 41 (Fig. 10)
which is held in contact with the peripherally indented or recessed cam wheel 43,
by the spring 42. Said wheel 43 is mounted on shaft 45, which is driven from
the auxiliary shaft 37 by intervening gears 46, 47, 48 and 49 (Fig. 4). Evidently
by this arrangement the wheel 43 is continuously rotated from the driving shaft
and the dog 41 during such rotation is held stationary until the depression 44 is
turned into such position that said dog is free to enter it. The spring 42 at this
time forces the dog into the depression so that the rock shaft 40 is turned sufficiently
to throw the saw 36 against the stock wire-it being understood that said saw 36 is
continuously rotated by a driving belt passing over pulley 50.
When stock wire has been fed into a die and cut off leaving in said die a blank,
the carrying plate is as aforesaid then rotated sufficiently to bring said blank in
position to be headed, and there lett stationary during the performance of such
operation. To effectively secure this, various mechanisms may be utilized which
will give to the plate the required partial turn, and then allow it to remain in its
new position a predetermined length of time. As a preferred construction,
mechanism is employed which is shown in detail in Figs. 4 and 9, the latter figure
being a rear view of the carrying plate.
Here the rear of the carrying plate C is shown provided with a series of radial

page_text: slots or guide-ways, 53, formed by the ribs 52. And a crank 51, whose pin 54 may
slide in said slots, is mounted on shaft 45, which, it is understood, is continuously
driven from the auxiliary shaft 37. It is evident from this arrangement that said
crank in revolving enters the slot or guide way 53 and during a portion of its
revolution drives the plate in the direction indicated by the arrow, until the blanks
reach the next operating mechanism. It then becomes disengaged, and pursues the
remainder of its revolution free from the plate, leaving the latter stationary and
free from the jar of moving machinery.
Upon reaching position 2 (Fig. 1) the blank is headed by mechanism arranged
to upset a portion of its length. In the preferred construction (shown in Figs. 11, 12
and 13) the auxiliary shaft 37 is shown bent so as to form a crank portion 55 which
drives the pitman 56 so as to rock the bell crank 57. Pivotally secured to
the other arm of said bell crank is the link or coupling 59, by means of which a
straight-line motion may be communicated to the stop 60. The latter may thus be
set securely against the die of the carrying plate and its protruding blank, so as to
hold the blank rigid while its opposite end is headed. For heading the blank, the
transversely bent portions 61 of the shaft 37 are rounded so as to act as eccentrics
to impart a reciprocating motion to the rod or bar 62, which is pivotally secured at
its opposite end to the lever 63. This lever 63 is designed to push the punch or
header 64 against the blank with such force as to upset a portion thereof so as to
form a head. In practice it is desirable to make the lever adjustable with reference
to the punch or header, and for this purpose interpose a screw 65 with its set
nut 66, which allows a nicety of adjustment otherwise difficult to attain and to
employ a spring 67 for withdrawing the punch or header, after it has done its work,
and the lever 63 with its screw 65 has swung back. It is thus apparent that
a single revolution of shaft 37 moves the stop for backing the blank, prior to
swinging the lever 63 to upset a portion of the same. This operation it is under-
stood, is so timed that it takes place when the plate is stationary-that is, when the
crank 51 is revolving independent of said plate.
The blank upon reaching position 4 (Fig. 1) is coned or beveled. For this
purpose, mechanism for shaving off a portion of the tip of the blank may be
employed.
In the preferred construction a rotary spindle 68, carrying a pulley 69, and
provided with a head 70 for grasping the tool 71 (Figs. 3 and 14) is journaled
on the drum or tool head B so that it may be moved longitudinally by any suitable
means, as for instance the vibratory lever 72. The tool 71 may be any suitable
rotary tool, internally reamed to correspond to the desired bevel of the nipple, and
provided with one or more cutting edges. Said lever 72 is swiveled to the rotary
spindle by the projections 73 of the fork 74 engaging with the groove 75 of
the adjustable collar 76 with which said spindle is provided; is pivoted to the rear
of the drum by the forked bolt 77; and terminates in the groove or channel in
the central collar 78 (Fig. 11). Said collar 78 is preferably mounted on the
projection 79 of the drum; is internally socketed; and is provided with an
extension to which may be coupled mechanism for its operation. Motion is
communicated to this collar from the main driving shaft 80 (Fig. 8) carrying the
spur-wheel 81, by intervening mechanism consisting of gears 82 and 83 (Fig. 3)
driving the gear 84 having the crank 85. The pitman 86, reciprocated by crank 85,
swings the lever 87 coupled to the collar 78 by the link 88. Hence, it is evident
that the continuous rotation of the power shaft 80 by pulley 90 alternately moves
the coning tool toward and away from the blank held in the carrying plate, by the
reciprocation of the vibratory lever 72 by the collar 78. It is understood that the
tool is continuously rotated by belting passing over pulley 69, so that it is necessary
only to urge the tool to contact with the blank in order to secure the performance
of its operation. Also, the coning tool, as well as the feed mechanism, the cutting
mechanism and the heading mechanism, operated as explained, from auxiliary
shaft 37, driven by main shaft 80 is arranged to perform its operation at a time
when the plate is stationary. And further, that inasmuch as, various other tools

page_text: are caused to operate simultaneously by the actuation of similar vibratory levers
by the collar 78, cach mechanism is operating while the plate is at rest, but
inactive (so far as the blanks are concerned) when it is being turned by the
crank 51.
The coning or beveling tool being withdrawn, and the carrying plate turned to
bring the blank to position 5, it is drilled to form the larger socket. As shown in
Fig. 15, a drill 91 carried by similar rotary spindle 92, is operated simultaneously
with spindle 68, by a like lever 93 similarly engaged with collar 78. At position 6
the blank is bored again as shown in Fig. 16 by drill 94, similarly operated
by lever 96, and at position 7 ie threaded as shown in Fig. 17 by tap 97.
Owing, however, to the necessity of withdrawing the tap so that its screw will
return in the threads cut by it, it is desirable to provide a reversible spindle, and
more delicate mechanism for engaging and disengaging the blank and tap.
For the latter purpose, a yielding or cushion connection with the vibratory lever
is found very efficient. In the preferred construction, shown in Figs. 3 and 5, it
will be seen that the spindle 98 is provided with two beveled friction wheels 99
and 100, either one of which may be brought in contact with a similar friction
wheel 101 on a shaft driven by pulley 102. Also, that the collar 103 is not rigid.
with said spindle, but is held between the portions of the divided spring 104. "In
order that the sheft 105 contained by this spring may not have to revolve with
the spindle 98 carrying the threading tool, said spindle is journaled in a movable
carriage 106, and the shaft 105 pivotally connected with this carriage, it being
observed that said spindle 98 is capable of longitudinal, as well as rotary motion
in the hearings of carriage 106, so as to permit the proper engagement of the bevel
wheels 99 and 100 with wheel 101.
Obviously, when the vibratory lover 99 urges forward the carriage 106, the
threading tool comes in contact with the blank, but does not enter it until the
carriage is moved sufficiently to cause the wheel 99 to come in contact with
the continuously rotating wheel 101. The spindle 98 then rotates and the tap cuts
a thread in the nipple, the spring connection with the vibratory lever 99 allowing
its forward motion to be the same as that which its rotation in a threaded socket
would naturally give it. When the blank is thus threaded the rearward movement
of the vibratory lever 99 permits the carriage 106 to recede, so that the bevels 100
and 101 are brought in contact, and the tap rotated in an opposite direction before
any rearward motion is imparted to it. And while being withdrawn the tap, by
reason of said yielding connection, is able to accommodate itself to the threads cut
when entering.
The carrying plate is then turned and leaves the blank at position 8, where it is
both slotted for a screw driver blade, and slabbed to afford purchasing surfaces for
a wrench. For this purpose a slotting device may be brought in contact with the
blank, and slabbing tools made to plane a portion of the blauk. As a preferred
construction (Figs. 4, 5, 19 and 20) an arm or bracket 108 is extended from the tool
head, which acts as a support and furnished a bearing for the bell crank lever 109.
Journaled in the bearing at the end of the short arm of this lever is the shaft 110
carrying the saw 111 and pulley 112. The long arm of the lever is connected by
a link or coupling 113 to a carriage 114, which in turn is connected by rod 115
to a similar, vibratory lever 116, and is provided at its forward end with shaft 117
carrying pulley 118 and the saws 119, mounted in parallel planes. It is evident
from this arrangement that when the earringe 114 occupies the position shown by
dotted lines in Fig. 19, the saws are at sufficient distance from the carrying plate
to permit the free rotation of the same with its series of blanks in the dies. When,
however, said carriage is urged forward by lever 116, the saws 119 are moved
toward the dial plate, and at the same time the lever 109 is rocked, throwing the
swinging saw 111 toward the head of the nipple. Owing to the short distance
which said saw 111 has to move, and to the relative arrangement of the parts, it
reaches the blank before the saws 119 have reached it from the opposite side, and
hence the blank is held against longitudinal movement which might take place if

page_text: the slabbing saws renched it first. The saws 111 and 119 being continuously
rotated by belts on pulleys 112 and 118 cat the desired portions from the nipples,
the former cutting a channel, or slot in the head, and the two latter producing two
parallel faces at its opposite end. In practice it is advantageous to provide
additional idle pulleys 120 and 121 (Fig. 4) and to arrange a single belt as shown
by the dotted lines passing it around pulleys 112 and 118 to rotate the saws, then
to the underside of 120 so as to obtain ample bearing surface on said pulley 118,
and then to 121 from which it may be led upward to a driving pulley.
The blank is now changed to a complete nipple and is ready to he removed from
the carrying plate, preparatory to the msertion of additional wire for the formation
of a new blank.
For this purpose at position 9 a spindle or extractor 125 (Fig. 22) having its
forward end turned to fit the die D is mounted on the tool head, and swiveled to a
similar vibratory lever 126. Hence the spindle or extractor is urged forward when
a die is left opposite it so that its reduced end 127 enters the same, and drives the
nipple therefrom. In order that the die as well may not be dislodged from its sent
in the earrying plate, an arm 128, is extended from the tool head and its beat end
portion 129 covers a portion of the die, thereby holding it in its place.
As aforesaid, it is desirable to have the carrying plate securely locked during
the performance of the above mentioned operations, so that accidental movement
of the same is guarded against, and at the same time the accurate adjustment of the
blanks for each operation is assured. For this purpose any locking device may be
employed, but as a preferred construction the simple mechanism shown in Fig. 23,
is utilized. This mechanism consists in the spindle or gauge pin 130, mounted on
the tool head, and arranged to be driven into one of the apertures E with which
the plate is provided. This gauge pin is, for convenience, placed in position 10
and is actuated by a similar vibratory lever 131. However, inasmuch as these
apertures E are nearer the center of the plate than the dies, the vibratory lever
for the gauge pin is shorter than the others, and as the gauge pin is made long
enough to extend very close to the plate when withdrawn, it will, although actuated
by collar 78 which actuates the tools, enter an aperture E before the tools reach
their allotted blanks, and will remain in said aperture for a short time after the
tools have completed their operations and been withdrawn.
An additional turn of the plate brings the empty die again to position 1 where
stock for a new blank is inserted, and the process continued as described.
With further reference to the reciprocation of the tools toward and away from
the blanks, it is found desirable, in many instances, to have the tools proceed very
gradually at the moment when they come into contact with the blanks, so as to
avoid any shock or breakage, and also to have them return, after they have reached
the end of their respective strokes, with a quick initial movement so that the
threads just cut in the blanks shall not be reamed out by the continual turning
even for a very short space of time, of the taps before being withdrawn. As a
simple and efficient mechanism for doing this there may be substituted for the
crank 85 (Fig. 3), a cam motion which is designed to impart to the pitman 86 a
slow initial forward motion, and a quick initial return. In Figs. 84 and 8B is
shown the gear wheel 84 provided with the cam 85" having the requisite curvature
to impart the desired motion to the pitman 86, when the wheel 86 with which the
pitman is provided, follows the periphery of said cam. In place of using a spring,
or other well known contrivance for keeping the cam and wheel together, a second
cam 85, is provided, which is the complement of the cam 85, that is to say, the
periphery of cam 85b is so curved that all the lines passing through the center of
the shaft 37, and having their ends respectively in the peripheries of one and the
other of the two came, shall have the same length. By then adding a second
wheel 86 to the pitman 86, located so that the distance between it and the
wheel 86 is equal to the common length of these lines, the pitman may be recipro-
cated without the possibility of any lost or irregular motion. The pitman
should, however, be maintained in its required relation with the cams; and for this

page_text: purpose is provided with a slot 86°, having the brasses 864 which serves as a
guide-way for the shaft 37, having the external flange or collar 37ª.
In this way the pitman 86 is held in place while reciprocating backward and
forward by reason of the positive cam motion to which it is subjected, and the
tools are actuated in the manner desired through the power transmitting connection
herein before described.

tion, and in what manner the same is to be performed, we declare that what we
