I, JOHN MARK CARLYLE of Portland Street Aston, Birmingham in the County of
Warwick Manufacturer do hereby declare the nature of the said invention to be as
follows:-
--
My invention is for the purpose of making buttons from such material as Ivory
or Corosso Nuts and refers in particular to the back part of the machine which may
be made to rotate to produce varied patterns but which does not necessarily do so
and which brings the work up to the revolving, cutter or fool which operates upon
or forms the face or other parts of the button. Great difficulty has been found in
quickly placing and holding a blank either roughly sawn or otherwise roughly formed
or already trimmed around its edge into a position sufficient to securo it against
turning without crushing the material and without giving the operator too much
trouble and fatigue. Now by my invention the material whether partly trimmed or
round will be instantly centred and an ascertained limited pressure will be brought to
bear upon it at the right moment without undue strain upon the work indeed so as to
give only the minimum amount of trouble and this I accomplish as follows:-
--
To a suitable slide fixed to the back of the machine I pivot jaws which are recessed
at the front end or points to hold the material or blanks to be faced or otherwise
operated upon and these jaws are operated by a wedge which slides between them at
the back end and by the same motion the slide may bring the jaws forward with the
blank against the revolving tool to form the face which is a similar process and works
in some cases well but in some work it is necessary to use a second motion when the
jaws are pivoted to the front of the main slide in the manner before described. The
main slide guides the wedge for closing the jaws which is gently accomplished by a
weighted lever the wedge being brought up to close the jaws by an arm and crank the
centre of which is mounted upon the main slide. The weighted arm or lever is
connected with a cord or chain or other equivalent and is attached to a spring in such a
manner that when the main slide is brought forward towards the operating tool—as will be
hereafter described the weighted lever or arm is further gradually pressed to the
measured extent of the strength of the spring which further tightens the wedge and

page_text: increases the hold of the jaws upon the blank or other piece to be held the strength being
suited to the particular work and material in hand. The handle for operating the main
slide is pivoted to a sliding plate which continues moving back independently after the
main slide is stopped at its back position by a stop bar a sufficient distance to press
against the arm of the crank which is connected to the back end of the wedge slide
thereby forcing the wedge from between the back of the jaws which allows the front
to open thus liberating the blank or piece held. The jaws are kept open which is their
normal position by a light spring or other equivalent. The sliding plate during its
travel forward comes against a stop on the main slide and carries it along with it.
The details for accomplishing the object in view may be greatly varied for instance
I may open the jaws by a pulley and cord and left and right handed screw one end of
the cord or chain being attached to a horizontal or other lever which is forced back
after the backward motion of the main slide has ceased by the sliding plate previously
mentioned thus drawing the cord or chain against the resistance of a spring fastened to
the other end of the cord thus turning the pulley and screws and operating the jaws.
The jaws also might themselves be outwardly formed as a wedge or conical and a ring
or sleeve slid over to close them or small eccentric rollers revolved by the forward
action of a wedge or grip slide or otherwiso.

Manufacturor do hereby declare the nature of my said invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
My invention is for the purpose of making buttons or other similar articles from
such materials as Ivory, or Corosso Nuts and refers in particular to the back part of
the machine which may be made to rotate to produce varied patterns bat which does
not necessarily do so and which brings the work up to the revolving cutter or tool
which operates upon or forms the face or other parts of the button. Great difficulty
has been found in quickly placing or holding a blank either roughly sawn or otherwise
roughly formed or already trimmed around its edge into a position sufficient to secure

page_text: Now by my invention the material whether partly trimmed or round will be instantly
centred and an ascertained limited pressure will be brought to bear upon it at the right
moment without undue strain and so as to give only the minimum amount of trouble
to the operator.
In order that my invention may be clearly understood and more easily
carried into practice I have appended hereunto three sheets of drawings upon which
is illustrated several examples of its application which will enable any ordinary work-
man to apply it to the general necessities of each case.
Figure 1 is a general side clevation of a machine made according to my invention
but with the back weight W in section.
Figure 2 is a plan of the same machine with the parts in the same positions as in
Figure 1.
Figuro 3 is a longitudinal vertical part section of the back part of the same machine
shewing the details which are generally dependent upon the main slide H which is for
convenience of manufacture really composed of the base H the cover H¹ of slide K
and the top cover H".
Figure 4 is a cross section on the line A. B.
Figure 5 is a cross sectional elevation on liue C. D. looking to the right hand.
Figure 6 is a longitudinal vertical sectional elevation of a machine with contering
holding jaws capable of turning round so as to produce various patterns upon the
work.
Figure 7 is an elevation of the front end of Figure 6.
Figure 8 is a part sectional longitudinal elevation of a modification of the plan
shewn by the previous Figures by which some of the details connected with the
weight W are dispensed with.
Figure 9 is a front end elevation of the machine shown by Figure 8.
Figure 10 is a broken off part longtitudinal vertical sectional elevation of another
modification by which the holding centering jaws are operated by a wedge upon
eccentric levers so as to produce a powerful rolling action in opening the jaws instead
of a sliding action as previously shewn.
Figure 11 is a front elevation of Figure 3 and shews the mouth of the jaws round
but they may be made of any convenient shape suitable for holding various shaped
blanks such as U. U. U and U³ shewn on sheet 3.
Figures 12 & 13 shew another modification by which the closing of the jaws is
effected by a ring sliding on outside at the front end so as to grip them together in
place of the wedge.
The disc F is assumed to be the material or button blank under operation and is held
between the top jaw E and bottom jaw E¹ against the cutter G which is fast in the
cutter holders hung upon a suitable spindle G' in the head stock G and rapidly
revolved by means of any suitable band upon the pulley G³ but my present invention
has no particular reference to the head stock part or to the revolving cutter. The jaws E
and E are both hinged to the jaw holders of the main slide H by the pivot pins e
for the upper jaw and e for the lower jaw. The back part of the jaws E aro bevelled
to receive the point of the wedge K which is capable of bringing more
or less
pressure upon the blank Fas it is forced forwards by the weight W and spring X or
backwards by the handle J in the following manner :-
The weight W in combination with the spring X has a constant tendency to force
forwards the wedge K and thus to close the jaws, the jaws being kept open when the
wedge is not in action by the compression spring e. In the first five Figures and
Figure 11 the blank F is shewn gripped with the combined force of the weight Wand
spring and also brought forward to the cutter G by the handle and secondary
slide M. The slide M has an oblong slot m¹ in which a projection h² of the main
slide H works so that the main slide H may when the pressure upon the bandle J
is relieved he carried back by the spring and weight acting upon the arms V over
the fuler arm N which is fast to the bed plate Y. The spring and weight are

page_text: nicely adjusted to hold the blank tight enough without crushing it and also to
overcome the friction of the main slide H in drawing it back. Thus the main slide
is carried back following the withdrawal movement of the handle J in the direction
of the arrow carrying the blank F with it.
its
Immediately however the main slide H has travelled to the end of the slot
further travel being prevented by the stop the slide M continues to move alone
until it comes against the lever P and thus relieves the pressure of the weight W and
carries the wedge slide K slightly backwards when the compression spring e opens
the jaws E and the blank F falls out. I am thus enabled to carry the blank F back
from the revolving tool before it falls out.
It will be noticed that the lever P is pivoted at pl to the brackets ³ on the main
slide H and is attached to the wedge slide K by the slotted hole p³ upon the pin k².
The operation of the handle J upon the slide M through the link L will be evident
without further explanation.
The modification shewn by Figures 6 and 7 only differs from the one previously
explained by the arrangement of the jaws E and E' so that they may turn bodily with
the blank F which is also shewn fixed and in its forward position near the cutter. The
wedge K in this case has a round taper or conical point and the back part of tho
jaws E are round so as to turn in the holder Q which is secured to the main slide H by
the set pins 7² 9³ and q².
The points of these pins turn in a groove / formed in a suitable collar at the point of
the main slide H. Any suitable indexing or dividing arrangement or device inay be
attached thereto as a guide to the operator in dividing up various patterns.
Figures 8 and 9 shew a simple arrangement for operating the slide H and wedge
slide K without the weight W or spring Q. In this case K may be made with a
piston and rod with the spring all placed in a recess in the slide H and operated
by a handle J and link L through the sliding nut working in the slot ' of the
slide H. The set pins h and regulate the distance of travel of each slide. In this
case however the normal condition of the jaws E is to be closed the spring
in tension.
being
To withdraw the blank or button when the slide has returned a hook or pointer R
may be mounted in a slot es in one of the jaws preferably the top one to turn it out.
In the case of the modification shewn by Figure 10 the eccentrics S and S¹ close
the jaws upon the blank F by a rolling action and in this case the spring e' is in
compression and keeps the jaws open and the other details of the first five Figures and
Figure 11 would be used with those jaws.
The jaws also may themselves be outwardly formed as a wedge or conical shape as
shewn in Figures 12 and 13 and a ring or sleeve Z slided over to close them the
pressure on the blank F being adjusted by the springs Z' and Z and the jaws released
on their return by the stop 7 forcing off the sleeve Z.
Having now particularly described and ascertained the nature of my said invention
& in what mannor the same is to be performed I declare that what I claim is
-
The improvements in machinery for making buttons or other similar articles by
which a blank F is placed in centering jaws and there held by a measured pressure
while the blank is brought forward when it is formed by the cutter substantially as
and for the purpose herein set forth.
