WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN MACHINES FOR TURNING
AND SHAPING THE ENDS OF BOLTS, STUDS, AND SIMILAR. ARTICLES, [a communi-
cation to him from abroad by George W. Bruce of the City and State of New
York, United States of America,]
This invention relates to machines for turning the ends of bolts, pins or similar
articles.
The object of the said invention is to provide devices or appliances more
convenient, durable and certain in operation than those heretofore employed for
carrying the said bolts or other articles, holding the same while their ends are
being turned, and delivering them, and for applying and withdrawing the cutting
tools.
In carrying the said invention into practice I provide any suitable feeding
conductor as usually employed in this class of machines. I place beneath this
conductor a vertical disc or carrier having in its periphery a series of transverse
V-shaped grooves arranged at regular intervals and adapted to receive and hold
bolts, pins or the like of different diameters, I also provide a guard which -
surrounds so much of the periphery of the said disc as may be necessary to prevent
the bolts or other articles from falling out of the grooves. The said disc is fixed on
a shaft having on its other end a ratchet-wheel arranged to be acted upon by a
spring pawl when not held by a spring latch, the alternate movements of the said
pawl and latch being controlled by cams arranged in any suitable manner whereby

page_text: the said disc receives an intermittent partial rotation so that the bolts or other
articles fall in turn into its grooves and in like succession are carried before the
cutter and are then delivered away from the turning scrap. A spindle, pressed
towards the said disc by a spring acting upon an adjustable shoulder or collar on
the said spindle, supports on its end next the disc a plate which covers the ends of
the carrier grooves but diverges at its upper end so as to guide the bolts into their
proper position and allow them to project as far as may be desired or as may be
necessary to suit the form of their ends. The aforesaid shoulder or collar is so
adjusted as to give the said guide the requisite degree of proximity to the disc
whilst the spring allows it to yield, should the intrusion of a larger article produce
an excessive strain thereon. To hold the article firmly against the action of the
cutter, a spring pin sliding through the front of the aforesaid guard is firmly pressed
upon the bolt or other article in the groove by means of a screw passing through a
block mounted on the end of a shaft acted upon by a spring lever so as to force
the said screw inward. The said screw is withdrawn when necessary by a cam
which raises the said spring lever. A lever is pivotted to the frame of the machine
and is drawn towards the said disc by a spring and pushed in the opposite direction
by a projection on a cam. This lever is connected to the cutter shaft by means of
a swivelled collar that is to say ;--a collar or ring passing over the said shaft and
pivotted thereon by means of two screws and the said lever acts upon the said shaft
to advance or withdraw the cutter and accommodate its pressure to small differences
of length in the articles to be turned.
A pulley is fixed on the cutter shaft, which pulley, by means of suitable gearing
on the said shaft and another shaft parallel therewith, gives motion to the different
parts of the apparatus.
I may modify the form and arrangement of the devices herein described without
changing the distinctive features which characterize the said invention

WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN MACHINES FOR TURNING
AND SHAPING THE ENDS OF BOLTS, STUDS AND SIMILAR ARTICLES." A commu-
nication to me from abroad by George W. Bruce, of the City and State of New
York, United States of America,
This invention relates to machines for turning and shaping the ends of bolts,
studs or similar articles.
The object of the said invention is to provide such machines with devices or
appliances, more convenient, durable and certain in operation than those heretofore
employed, for receiving and carrying bolts, studs, pieces of wire or similar articles;
holding the same while their ends are being turned and then delivering or releasing
them, and for applying and withdrawing the cutting tool or tools.
The said invention is illustrated in the accompanying drawing, in which
Figure 1 is a front elevation of the improved machine, a portion thereof being
omitted.
Figure 2 is a plan of the said machine.
Figure 3 is a section on the line x, x, Figure 2.
Figure 4 is a sectional elevation shewing some of the improved devices or
appliances, and
Figure 5 is an end view of part of the machine.

..Like letters indicate the same parts throughout the drawing.
A is a vertical disc or carrier having a series of transverse grooves a formed at
regular intervals in its periphery and made partly V-shaped as shewn (or they may
be entirely V-shaped) so that they can receive and hold bolts, studs or similar
articles of different diameters. The said bolts or other articles can be fed to the
disc either by hand or by suitable feeding mechanism, and are placed in the
grooves as they successively arrive at their highest position.
.
B is a guard surrounding so much of the said disc as may be necessary to prevent
the bolts from falling out of the grooves. The disc A. is fixed on one end of the
shaft C, and on the other end of the said shaft is fixed the ratchet-wheel D arranged
to be acted upon by the pawl E when not held by the spring-latch H. This pawl
is attached to one end of the lever F which is acted upon by the spring F1; the
other end of the lever F is arranged to be acted upon by the cam G; the alternaté
movements of the pawl E and latch H are controlled by the cams G and I. The
disc A thus receives an intermittent partial rotation, so that the bolts or other
articles, which fall in turn into its grooves, are successively carried before the
cutter K mounted in the revolving cutter-shaft hereinafter described, and are then
delivered away from the "scrap," that is to say, the pieces of metal which are cut.
from the ends of the bolts or other articles. Any other suitable means may,
however, be provided for intermittently rotating the said disc.
L is a spindle which is pressed towards the disc A. by a spring M secured to the
frame of the machine, and acting upon an adjustable shoulder or collar N on the
said spindle. This spindle carries at one end a plate O which faces the ends of.
the carrier-grooves a on the front edge of the disc A. This plate diverges at its
upper end from the said disc, so as to guide the bolts into their proper position and
cause them to project as far as may be desirable or necessary. The shoulder or
collar N is adjusted to regulate the proximity of the guide or plate O to the disc A,

page_text: whilst the spring M allows the said plate to yield, should the entrance of an
abnormally large bolt or other article produce an excessive strain thereon.
To hold the article firmly against the action of the cutter K, I provide a spring
griping pin P which slides through the front of the guard B and is firmly pressed
against the bolt or other article in the groove a by means of a screw R passing
through the end of the shaft S which is so formed as to constitute the short arm of
a lever. On this shaft is fixed a lever or arm T acted upon by a spring T¹ so
as to force the screw R and pin P inward. The lever or arm T is made with a
projection T through which is passed an adjusting screw T³. The pressure of the
screw Rupon the-pin P is removed, when necessary, by a cam U that raises the
spring-lever T and moves the screw R away from the pin P which is then withdrawn
by a spring p. A lever T (Figures 1 and 2) is pivotted to the frame of the machine.
A spring Vitends to draw this lever towards the disc A, and the said lever is pushed
in the opposite direction, when necessary, by a projection W' on the cam W. This
lever is connected to the cutter shaft Y by means of a collar or ring Z fitting
loosely upon the said shaft between two fixed collars Z', and pivotted to the lever T
by means of two screws z. z. The lever Tacts upon the shaft Y to advance or
withdraw the cutter K and accommodate its pressure to small differences of length
in the article to be turned.
A driving pulley y is fixed on the cutter shaft Y, which shaft, by means of the
pinion Y and the gear-wheel S2 on the shaft S', imparts motion to the various
parts of the machine. The pinion Y' is made of sufficient length to permit the
axial movement of the shaft Y as above described.
It is obvious that I may modify the form and arrangement of the devices herein
described without departing from the nature of the said invention.
Having thus fully described the said invention as communicated to me by my
foreign Correspondent, and the manner of performing the same, I wish it understood
that I Claim
First. A revolving carrier-disc with one or more grooves. for receiving, holding
and carrying bolts, studs, or other articles, substantially as, and for the purpose, set
