County of Warwick do hereby declare the nature of this invention to be as
follows:-
:
Having arranged the "Gripper," carrying work operated upon, to turn at regular
intervals, at right angles, with crank shaft, over Perforating Die, and obtained the
required reciprocal motion of Perforating Punch, by fixing it to a sliding bolt
worked by a crank, this in turn being driven by pulley, 1st Attached to and
forming part of, bearing of crank shaft is a flat ring, in which, is cut a T groove
and on outer edge is turned a shoulder half across both being concentric with crank
shaft. 2nd A strong frame, carrying the sliding bolt, the lower part of which, is
a ring or part of ring corresponding to ring on bearing, but having outer edge
to fit over shoulder previously described. These are held together by two or more
bolts and nuts, beads of which are inserted in T shaped groove, thus enabling
frame to be set at any angle in which the sliding bolt is required to move, at the
will of the operator the said rings, being made to fit each other internally, and
externally, and, tightly bolted together, (when set), enables the perforation of
Paraffin Lamp Bodies, Lamp Glassholders, and similar conical and cylindrical
articles to be performed, rapidly and without vibration.
Note A. The first mentioned ring (or circular plate) forming part of Bearing, has
the T shaped groove made the exact size of the heads of the said bolts, just
allowing them to be moved in the said T shaped groove, as required.
Note B. The other (ring, or circular plate), forming the connection between the
Frame carrying sliding bolt, and bearing aforesaid, has holes for the pins corre-
sponding to the diameter of T shaped groove, and as this ring forms a cap on the
first mentioned ring makes the Frame carrying sliding bolt firin and rigid when the
bolts are tightened and allowing the Frame to be set at any angle to suit work
required.

tion of Paraffin Lamp Bodies, Lamp Glassholders, and similar
Articles.
I JOHN MORTON, of 34 Gladstone Street, Aston, near Birmingham, in the
county of Warwick, Engineer and Machinist do hereby declare the nature of my
invention for IMPROVEMENTS OF MACHINES FOR THE RAPID AND STEADY PERFO-
RATION OF PARAFFIN LAMP BODIES, LAMP GLASS HOLDERS, AND SIMILAR ARTICLES,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention has for its object improvements in the construction and arrange-
ment of machines, and also parts of such machines for the perforation of lamp
bodies, lamp glass holders, and similar articles, being a much more compact, simple
and convenient arrangement than any hitherto in use, the nature of which consists
as follows: Having arranged the gripper carrying the work to be operated upon,
to move with an intermittent motion at regular intervals, this line of motion being
at right angles to that of the crank shaft, also a reciprocating motion to the punch,
which latter is attached to a sliding bolt or head which head is made to swivel or
turn to any required angle as follows:-
Attached to and forming part of the front bearings of the crank shaft is a flat
ring, in which is cut a T groove, the outer edge of which ring is turned so as to
form a shoulder, to a depth equal to about half the thickness of the metal forming
such ring structure. This ring is concentric with the crank shaft. This T shaped
groove being for the purpose of receiving the heads of the T headed bolts herein-
after described. Further a strong frame or bracket is provided for carrying the
sliding bolt or head, having upon its rear side or face an annular ring or part of a
ring, (which corresponds to the ring already described, upon the bearing of crank
shaft) having its outer edge made to fit over the shoulder previously mentioned.
Concentric with this ring, and corresponding to the T headed groove upon ring
attached to crank shaft bearing, I provide a suitable number of bolt holes; bolts
are first inserted in the T headed groove, then the slide frame or bracket is passed
on to the concentric ring upon crank shaft bearing; the bolts passing through the
holes provided in the slide frame or bracket, when by tightening up the said bolts,
the said bracket may be secured rigidly at any desired angle.
In order to explain this my invention more clearly I have appended hereunto
illustrative sheets of drawings. I will therefore proceed to describe it more fully
having reference thereto.
Fig. 1 is a side elevation of a machine constructed according to these my
improvements.
Fig. 2 is a plan of such machine.
Fig. 3 is a front elevation of the machine. Like letters of reference throughout
are made to indicate the same parts in each view.

page_text: The driving shaft a, of the machine receives motion from the pulley b, by means
of a key c. A central hole is drilled up the shaft a distance about as far as the
revolving sliding block d; a bolt or slide e, is made to easily fit this hole; at the
outer end of this bolt a plate f is attached, the upper part of which is made of a
cylindrical form to engage in a circular hole formed in the end of the key c. The
fly wheel is made to revolve freely upon the shaft a, but has a key way formed in
it for about half way through its nave (or boss) and made much wider than the
key, in order that the latter may easily pass therein. g, is a fixed boss which
keeps the fly wheel in position, and also through which the key c passes, thereby
forming a support and guide to the said key. d, as before mentioned is a revolving
sliding block, that revolves with the shaft but is capable of a sliding motion axially.
This block d is connected to the key c by means of a screw pin h, so that when
the block slides, the key will slide therewith, and so advance the said key into or
out of gear with the fly wheel.
At upon the block d, a groove is provided so that the sliding motion may be
imparted by means of a lever j, having a forked end with studs to work therein.
At k I form a frame or standard which for the sake of rigidity is shewn attached
to the bearing m. Upon the front or plate part of the standard k, I form a ring
of metal n, (see Fig. 4) which is turned concentric with the shaft u. In this ring
a T headed groove o is formed: corresponding to this concentric T grooved
ring, I form a plate or bracket p, which is made to fit the said ring n,
being also provided with bolt holes to receive two or more bolts q. By slacken-
ing these bolts it will be seen that the bracket p may be turned to any angle,
and then secured by tightening the T bolts. This bracket is then extended
in form to carry and form the slides for the punch bolt or head r; motion is given
to this head r, by means of the crank pin s, and connecting rod t. Fig. 5 shews
a detail view of this connecting rod end. In the necessarily confined position of
the crank pin, it is somewhat difficult to fix, and also to take up the wear of the
crank pin bearing in ordinarily constructed rod ends, but in these my arrangements
it is easily attached and adjusted, and at the same time, the strain due to the
resistance of the punch is not carried by any bolts or pins, but direct on to the
rod itself; the caps being held in position and adjusted by means of the pins t².
The punch u is carried in a holder v, which is capable of an up and down
adjustment. A shallow groove the width of this holder is prepared in the head r,
also a hole to receive a bolt or pin w. The holder v has a slot hole formed in it to
receive the said bolt or pin w. By slackening the bolt or pin w, the punch may
be raised or lowered, and thus adjusted into position, when, by tightening up the
bolt or pin w, the holder is rigidly held in position. It will be seen that this
arrangement has two good qualities, it is found very easy after once setting the
holder in position by means of the screw x, to readily take out the holder with the
punch, to grind or otherwise attend to the latter, and then re-attach the same
without any re-setting, also that when at work, the resistance to the punch does
not depend upon a screw thread, but is carried by the holder being firmly bolted to
the head.
The work to be operated upon is placed upon the mandril y, which is made of a
shape corresponding to and suitable for the said piece of work. This mandril is
firmly bolted to the bracket z, but is capable of an up and down adjustment by
means of pin a'. The piece b', is fitted to the bracket as shewn, having a hole to
correspond with the shank or bolt c', of the mandril. In the bracket z, however
the hole through which the shank passes is made a little slotwise, the pin a¹ is
tapped in the piece b¹, and passes right through on to the bracket at the bottom,
so that when the shank c is slackened, the steel piece b¹ may be raised or lowered
by means of the pin a¹. The purpose of this adjustment is this; Having reference
to Fig. 6; when the shape of the work to be operated upon is such that a portion
of it at or near the front d¹ (that part nearest to the shank of the mandril) is
smaller in diameter, than any portion of such work nearer to the gripper or chuck

page_text: say at el, it is necessary to make no part of the said mandril larger in diameter
than the part of the work at d. Thus the upper part of such mandril would form
bedding surface for the die face, but when the work rested thereon, its centre
of rotation would be lower than the centre of the mandril to the extent of about
half the difference in the two diameters, therefore by the screw pin a¹ this is raised
or lowered to suit such variations, and to bring the centre of the work in line with
spindle ¹.
The bracket may be adjusted by means of pins. Upon the upper part of the
mandril y, is formed the die. At the front end of this mandril y, when used for
articles having a metal end, such as lamp galleries or bodies, I should provide
a loose revolving centre g', Fig. 7, having upon its front face, notches or teeth, and
its shank (within the mandril) finishing in a pivot form. Ordinarily, unless pre-
vented by a garter pin or other similar device, these revolving centres are apt to
fall out when there happens to be no work being operated upon, but I turn a small
groove in the shank of such centre at I, (Fig. 7) and spring a circular bent piece
of steel over into such groove, which, when passed together with the shank into
the mandril y, binds slightly against the hole in the said mandril, and prevents the
centre falling out.
I also form notches or teeth upon the front of the gripper . Between these two
notched or toothed surfaces, the work to be operated upon is in some cases held, or,
in other cases a chuck or other similar device would be substituted for the gripper ".
Otherwise than this method of preventing the revolving centre from falling out,
the parts forming the mandril, mandril bracket, adjusting die, &c, in order that the
work to be operated upon may revolve thereon, is made similar to those already in
use for some years. The gripper ¹, is connected to an intermittent revolving
spindle, which receives its motion from an exterior sleeve le¹, by passing there-
through, and having a feather keyway cut in its length, and a key provided at U,
or other convenient place. Upon the sleeve k¹, is mounted a ratchet wheel m', acted
upon by a pawl n'. A two and fro motion is imparted to the pawl, by means of
a cam o, acting upon roller p¹, which rocks the shaft q', which in its turn rocks
lever, thence to rod a', and thence to lever upon which the said pawl is
mounted. This roller p' is kept against the cam o' by means of spring w. The
rod 8' is capable of adjustment to length by means of the sliding joint and set screw
at v. The back travel of the pawl may be also adjusted by means of the pin w³
acting upon the arm x, extending from the rock shaft q¹.
The gripper &c ', is held up against and grips the work to be operated upon, by
means of the arm y', which is capable of a sliding motion in the bed of the machine,
and is pulled in that direction by the spring .
By this arrangement the pressure of the gripper can be readily put on or taken
off, by taking hold of the arm and withdrawing it from the end of the spindle j*.
At a I provide an adjustable releasing or stopping motion by which means the
machine may be automatically stopped at any point of the revolution of the work,
and also by which the work being operated upon, may be automatically advanced a
distance equal to one or more teeth of the ratchet wheel. In perforating lamp
galleries or other similar articles, it is sometimes desirable that at a certain part of
its circumference there should be no perforations for a short distance, that is, the
work shall travel a certain distance before the next descent of the punch; this is
effected in the following manner :-
Upon the sleeve k¹, is a piece having a flange c³, a portion of which is removed
similarly as shewn in Fig. 8 at e².
Upon this flange I also put an adjusting plate d*, which may be made to move
round such flange, and open or close the opening e Now when the opening e
came opposite the stud 6, the said stud would, by reason of the spring i e, be pulled
into the said opening, and thereby give motion to the rod 2, the lever j, and the
block d, and so the driving key would be thrown out of gear, and the machine
stopped. Thus far, that is the stopping, can be, and is already accomplished in

page_text: similar machines, and in a similar manner, and where such is the case, the work nas
to be advanced forward by hand the distance required for the blank space, and then
the machine re-started; by my arrangement however, this given distance is measured
automatically by adjusting the width of the notch or gap e, wherein the stud 6²
drops, and in conjunction therewith providing upon the rock shaft q', a arm or
lever, near to the rod j³, upon the which latter I mount an adjustable stop m². It
will be now seen that when the stud b², drops into the notch or opening e², upon the
flange c, the rod, is allowed to advance so as to stop the machine, and in so doing
the stop m² strikes the lever 1, which by reason of its connection, through the rock
shaft q, lever, and rod s¹, the pawl n', and consequently the work being operated
upon, is carried round some distance; this said distance being governed by the width
of the opening e³ Fig. 8.
The amount of motion given to the rod je would be governed by the depth of the
notch or opening e², in the flange c², and preferably a little greater than is necessary
for the withdrawal of the key, so that the advance or feed required for the "blank
space" may be made while the machine is practically at a standstill.
It will be seen that if the width of the opening e² were only equal to the diameter
of the stud b, as shewn in dotted lines, the said stud bª would simply fall therein
and there could be no advance of the flange c², (and consequently none of the work),
but, if the opening c² was widened as shewn (in plain lines) then the flange c³, &c,
would be advanced a distance equal to the width of such opening, by reason of the
spring, being more powerful in action than the spring w₁, when the said spring 2
draws the stud 62 into the opening, the stop m³ at the same time strikes the lever 12,
overcoming the opposite pull of the spring w¹, and thereby drives the pawl n¹
forward, until checked by the rear part of the width of the opening e² coming in
contact with the stud 63, carrying the work forward to the same amount. The
attendant could then re-start the machine, either by pressing the foot lever n², or
pulling the lever 92 back into position. If necessary according to the requirements
of the perforations, I may provide more than one such opening e2, Fig. 8, and also
adjusting plate d². The machine can however be stopped at any time by lifting
the handle g when the spring will throw the driving key out of gear as before
described. p is a lever acting upon the gripper spindle whereby the gripper may
be held back while the work is readily put in or taken out.
One advantage which the arrangement of this machine affords is that by reason
of the driving shaft being low down, the point of the cutting punch, when swivelled
to different angles, does not move but little from the same point, thus necessitating
but a very small amount of adjustment of the die, and gripper spindle.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I wish it to be understood
that I am aware that many of the parts, and some of the motions forming my
complete machine are old, having been in use for some time, and therefore I do not
claim each part or motion of itself as being new, but what I do wish to claim as
new is:
1st. In machines for the perforation of lamp bodies, lamp glass holders, and
similar articles, the use of a swivel punch head, having a concentric shouldered
ring, and fitted with T headed bolts, working in a T headed groove upon a
counterpart of the machine, with slides, the adjustable punch holder, and fixed
pin for connecting rod end, combined, as hereindescribed and shewn upon the
drawings.
2nd. In these perforating machines the method of forming and adjusting the
crank pin connecting rod end, as hereindescribed and shewn upon the drawings.
3rd. In these perforating machines the method of applying pressure to the
gripper spindle by means of the arm y¹, and spring 2¹, as hereindescribed and
shewn upon the drawings.

page_text: 4th. In these perforating machines the method and arrangement of the combined
adjustable stop and advancing motion, that is to say those parts by which the
work being operated upon, may be advanced a given distance without perforation
taking place, as hereindescribed and shewn upon the drawings.
5th. The combined general arrangement of parts forming a machine for the
perforation of lamp bodies, lamp glass holders, and similar articles, substantially as
hereindescribed and shewn upon the drawings.
