COMPLETE SPECIFICATION.
Improvements in Machines for Drilling and Trimming Nipples for
Cycle Spokes and similar Articles..
I, ARTHUR JACOB MORSE, of the Town of Salisbury, County of Litchfield, State
of Connecticut, United States of America, Machinist, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be particu-
lariy described and ascertained in and by the following statement:-
My invention relates to machines for trimming the ends and drilling nipples
for bicycle spokes or analogous or similar devices, and the object is to provide a
machine that will operate on several nipples or other articles simultaneously,
producing a somewhat different operation on each, and that will operate upon a
series of nipples successively.
To this end my invention consists in the combination in a nipple finishing
machine, of a disk provided with chambers to hold the nipples, means to rotate
the disk intermittently, a longitudinally movable bar, the driving shaft, a cam-
wheel on the driving shaft to move the bar, a spindle adapted to be reciprocated
in bearings by the said bar, a chuck on the end of the spindle to hold a tool to
operate upon the nipples, and a pulley on the spindle for rotating the same.
And my invention consists in certain other combinations of parts hereinafter
described and specifically set forth in the claims.
In the Drawings hereto annexed and forming a part of this specification,
Figure 1 is a top plan view of my invention,
Figure 2 is a front side elevation
Figure 3 is the rear side elevation,
Figure 4 is an end elevation looking from right to left of Figure 1,
Figure 5 is the same end view of some of the important movable parts shown in
their operative position, or the reverse of that indicated in Figure 4,

and C are parallel with each other and lie with their axes in the same horizontal
plane.
machine having
to turn in, and
The spindles B
The driving shaft, D, carries a pair of cam-wheels D¹ and D", the cam surface
of each being on one side of the rim, and on the sides facing each other. These
can-wheels operate upon a pair of longitudinally movable bars E¹ and E", sliding
in a guideway, E, arranged on the top of the frame, A, parallel with the driving
shaft, D, through a pair of small rollers, d¹ and d¹¹, turning on one side of the
sliding bars. The right hand end of bar E¹, slides in another bearing, e, on the
[Price 8d.

page_text: frame. The sliding bars, E¹ and E", are in line with each other and are carried
toward each other by the cam-wheels simultaneously as hereinafter explained.
The bar, E, is connected by a forwardly and horizontally extending bar, F, with
the right hand ends of the spindles B and C to reciprocate them in their bearings
while they are being rotated by continuously running belts (not shown) on their
pulleys B and C¹. The sliding bar E¹, and the spindles B and C are threaded
where they pass through the bar, F, so that nuts, fif, and f, f¹, on said bars and
spindles on opposite sides of the bar, F, may properly adjust the bar F. The
left hand ends of the spindles are shown provided, one with a trimmer chuck, c,
and the other with a drill chuck, c¹, so that both operations may be effected on a
pair of nipples at once; but if preferred both chucks may be either trimmer-
chucks or drill-chucks, and if both are drill-chucks, the chuck or spindle, B, may
carry the drill for the smaller hole in the nipple-the hole that is threaded as
indicated in Figure 12 of the drawings, while the other chuck may carry the
larger drill for the unthreaded portion of the spoke to enter. It becomes necessary
in this case, as is obvious, to extend one drill farther than the other and this may
be effected by turning the nuts f, f¹, on the spindles in the proper direction.
The sliding bar, E, has a bar, F, similar to F, secured to one end thereof
and extending in the same direction and in the same horizontal plane as the
bar F. This bar, F, is on the opposite side of the disk, G, carrying the nipples,
and is provided with adjustable screws g and g¹ extending through it, in line with
the spindles B and C on the opposite side of the disk, G, which are for the
purpose of bearing on the heads of the pair of nipples being operated upon by the
trimming cutters or the drills. The ends of the screws and g¹, serve to hold
the heads of the nipples firmly in place in their countersunk chambers or apertures
and prevent them from turning. The cam-face on the wheel, D₁, is so shaped as
to force the screws, g and g¹, against the heads of the nipples immediately after
the disk has shifted and before the trimmers or drills begin to act on the nipples.
And said screws are moved from the heads after such operation is completed, when
the disk, G, is again turned.
Coil springs h and h¹ are connected with the sliding bars by pins projecting
through slots in the guideways to retract the bars.
X is the driving pulley on the driving shaft. The disk, G carrying the nipples
to be operated upon is secured upon one end of a horizontal shaft, G¹, which turns
in bearings, g¹¹ and g¹¹, in a bracket, G", secured to the front side of the frame A.
The disk, G, is provided with a circular and concentric series of holes or
chambers, a, a, etc., which extend through it near its periphery to receive and hold.
the nipples. Twenty holes are shown in the disk in the drawings and these holes
are just large enough to admit the shanks of the nipples, which before they are
trimmed resemble common rivets and are countersunk slightly to receive the
heads. Countersinking the holes, x, helps the screws, g and g¹ to hold the nipples
from turning.
The nipples are inserted by hand in the lower part of the disk which revolves in
the direction of the arrows shown in Figures 1 and 4. When a nipple reaches
a point forty-five degrees above a horizontal plane extending through the axis of
the shaft, G¹, it is trimmed and centred by the knives in the trimming chuck, as
indicated in Figure 11 of the Drawings. After which, it is carried, step by step,
-a nipple being trimmed at each step by the same chuck-a distance of ninety
degrees, when it is in position to be drilled by the drill in the chuck c¹.
After the same nipple is carried by the disk to nearly its lowest point, it is in
position to be removed by the rod, H, extending horizontally near the lower part
of the frame. The said rod is in line with one of the nipples in the disk when the
trimmer and drill are operating upon other nipples; and as the rod, H, which may
be termed a pusher, is connected to and operated by the bar, F, it pushes a nipple
out of the disk every time the spindles B and C are moved toward the disk.
The pusher, H, is reciprocated in an aperture in the end of a depending arm, i,
secured by a bolt to the web below the bearing g¹¹. The end of the pusher

page_text: farthest removed from the disk is secured adjustably in the lower end of an angular
arm, H', secured to the bar F.
The shaft, G¹, is rotated intermittently by means of a ratchet wheel, J, on the
end opposite that carrying the disk G. The ratchet wheel is provided with as
many teeth as there are holes for nipples in the disk, the number in this case
being twenty. The recesses in the periphery, or the spaces betwen the teeth are
shown square and are preferably made so, in order that the disk may be held
positively against movement in either direction during the trimming and drilling
operations.
J is the pawl for turning the ratchet-wheel, J. Said pawl is connected at one
end with a lever, K, which is pivoted at its lower end to a projection, 7, extending
from the angle of a bell-crank lever L, which is in turn pivoted at its angle
to the frame A. One arm of the bell-crank lever extends horizontally to and below
the ratchet wheel, and its end is adapted to enter the recesses therein and forms
the detent of said wheel; and the other arm extends vertically and is in position
to be impinged by an adjustable screw, k, passing through the lever K. A coil
spring, m, connects the pawl, J¹, with the detent arm of the lever, L, and serves
to draw them toward each other. Another coil-spring, n, is connected between
the pawl, J, and a bracket, I, secured to the frame to operate on the pawl to turn
the ratchet wheel J. The pawl, J', is moved in the opposite direction and the
detent removed from the ratchet-wheel, by means of a cam, or, as shown in the
drawings, a projection, p, carrying a small roller, p', extending from a sleeve on
the driving shaft. D. As the said projection, P, revolves around the shaft, the
roller strikes the lever, K, which carries the pawl, J', forward to enter another
recess in the ratchet wheel. Just before the pawl reaches the end of its move-
ment, the screw, k, strikes the vertical arm of the bell-crank lever, L, which throws
the detent out of the recess in the wheel. As the roller, p, moves out of engage-
ment with the lever, K, the spring, n, draws the pawl back, turning the ratchet
wheel and allowing the detent to fall into the next recess to hold the wheel against
movement while other operations are performed on the nipples in the disk, G.
The usual form of drill-chuck is employed. The trimming chuck is flat with
a recess, q, in one side. r is the aperture to admit the nipple; r is the centering
bit or cutter to prepare the nipple for the drilling operation, and s is the trimming
cutter which reduces the diameter of the end of the nipples, as shown in Figure 11.
Both of these cutters are provided with adjusting or set-screws to hold them in
place in the chuck.
I do not wish to be limited to the precise construction of the parts shown in the
drawings, for it will be obvious that they may be changed in form without
departing from my invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
