We, HENRY BAYLEY, Cotton Manufacturer, of Stalybridge, LEOPOLD NEWTON,-
Cotton Spinner, of Oldham, and JOHN GREAVES, Manager, of Stalybridge,
all in the County of Lancaster, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR TURNING, BORING, CUTTING,-
SHAPING, AND REDUCING WOOD, AND OTHER SUBSTANCES APPLICABLE FOR THE.
MANUFACTURE OF VARIOUS ARTICLES," to be as follows:-
Our improvements relate to self-acting machinery for making cop tubes,.
spools, bobbins, and other articles from long blanks of wood and similar
materials, each capable of forming several articles, and it consists in the com--
binations and arrangements of mechanism described as follows:-
We prefer, first, to reduce the long blanks which are square as they come
from the saw to the cylindrical form, a little larger than the largest diameter of
the article to be formed, and accomplish this by a rotating hollow shaft upon the
end of which suitable cutters, are secured, so that when the end of the square-
blank is presented and forced forwards into the hollow rotating shaft these
cutters will operate upon it and reduce it to the cylindrical form; the long:
blanks are fed to the rotating cutters by pinching rollers and suitable guides.
placed in front of the cutters, and when the front end of the blank has passed
through the hollow, shaft it is received by another set of pinching rollers which

page_text: serve to hold the blank from revolving, and pull it through the cutters when the
latter end of the blank has left the first set of rollers. The cylindrical blanks are
now ready for the second machine, which consists of a hollow shaft rotating in
suitable bearings, and at one end of the hollow shaft a pair of moveable dies,
jaws, or holders are placed in a box or face plate; these dies are worked by
inclines on a disc moveable endways on the exterior of the hollow shaft by
a clutch fork lever. At the front and opposite the end of the hollow shaft a
small slide carriage is arranged to hold and actuate the bit for boring the hole in
the article, this slide carriage being arranged to slide in a line with the axis of
the hollow shaft. Another slide carriage is arranged at about a right angle to the
axis of the hollow shaft, which carries the tools for turning, cutting, or shaping
the article. In place of our slide carriage two or more may be arranged if the
cutters necessary to produce the required shape have to act at different times.
The pinching arrangement at the end of the hollow shaft and the slides carrying
the boring and cutting tools are actuated by cams and suitable transmitting levers
and the feeding motion is also actuated by a cam; it consists of a toothed rack
eapable of sliding endways, the teeth of the rack are equal to the length of blank
to be fed, for each article. The rack receives a reciprocating motion in length
equal to the pitch of its teeth, this toothed rack gives motion to a slide carriago
arranged on a slide path in a line with the axis of the hollow shaft. This slide
carriage holds a "she centre "in which the end of the blank rotates when
entered into the hollow shaft, and the blank is pushed forward intermittently
by this "she centre," as required. Two ratchet pawls are hinged upon the
'feeding slide carriage, one enters the teeth of the reciprocating rack, the other
a fixed toothed rack of the same pitch; the fixed rack prevents the slide feeding
carriage from being pushed back, and the reciprocating toothed rack pushes the
'slide feeding carriage forward. The mode of action of this machinery is as
follows-The blank is fed forward through the pinchers on holders in the hollow
áxis till it projects sufficiently, then the boring tool enters and bores the hole, and
when it is about retiring the turning, shaping, and cutting tools are brought
into action, the cutting tool last in action being that which severs the article
formed from the end of the blank. The article falls and enters a proper
receptacle, and then the blank is again fed forward by the feeding cam and
the operations are repeated. When the blank, bas been pushed to the limit
of the feeding slide carriage, the attendant withdraws the ratchet pawl from
the toothed racks, draws back the slide feeding carriage and enters another
blank. We prefer to make the machine double, in which case the same
cams actuate both, except that the times of action alternate. In place of the cam
and toothed racks for feeding a screw may be employed which may be actuated

page_text: intermittently as the feeding is required by a cam and ratchet wheel or
otherwise, the sliding feeding carriage being connected with the screw by
a half nut capable of being made to geer or ungeer with the screw threads;
and in place of the nipping holders in the hollow rotating shaft actuated by
5 a cam, slightly fluted holders may be used pressed against the blank by a
spring, so as to hold the blank sufficiently fast for the boring and cutting
operation, but not to resist the feeding motion.
