Year: 1878

page_text: LETTERS PATENT to Frederick J. Taylor, of Wakefield, in the County of York,
Engineer, for the Invention of "IMPROVEMENTS IN MACHINERY FOR CUTTING,
DRAWING, FORMING, AND STAMPING SHEET METALS."
Sealed the 30th May 1879, and dated the 7th December 1878.
PROVISIONAL SPECIFICATION left by the said Frederick J. Taylor at the
Office of the Commissioners of Patents on the 7th December 1878.
FREDERICK J. TAYLOR, of Wakefield, in the County of York, Engineer. "IM-
PROVEMENTS IN MACHINERY FOR CUTTING, DRAWING, FORMING, AND STAMPING
SHEET METALS."
This Invention has for its object the construction of a combined machine having
interchangable parts so as to perform all the above operations on one machine.
The Invention also relates to an improved clutch by which the machine may be
readily put in and out of gear or work.
A machine according to this my said Invention comprises a press having solid
bearings, to which is attached a plate. To the bottom of the slide I fix a die or
other tool; I also apply a plate with screw adjustment to accomodate the different
thicknesses of metal to the bed plate or plate on which the metal to be operated
upon is placed, or the punch or pressure tool may be adjustable so as to place the
work nearer to or further from the punch or pressure tool.
The slide I raise by means of a weight, the downward motion being obtained by
cam or eccentric, or a cam may be employed for giving positive motion to the slide
in both directions. For impressing name, trade marks, or other indentations after
the article is formed in the press, I use a slide and die working within a casing
under the main dye, so that the under die will be worked (by preference) after the
main operation of forming the article is completed.

page_text: The bottom of the die or "burring" edge used in the manufacture of flanged
circular covers, bottoms, or ends of cans, keys, or cylinders, I construct of a ring of
steel, so as to be renewable when worn out. The machine may be moved from the
vertical to an inclined position by means of a segment rack and pinion wheel.
When the machine is being used for working metals giving off scale or refuse, a
passage way for escape of the same is provided, the vibration of the machine in
work causing the refuse to pass to and outward by the passage way.
The clutch comprises a pin passed through a clutch block; the other end of the
said pin acts upon an incline, thereby withdrawing the pin clear of the boss of the
driving wheel, which is thus free to run loosely upon its shaft.
The dies and working parts of the machine are so arranged that the work as
completed may be carried through or lifted out of the dies.

This Invention has for its object the construction of a combined machine having
interchangable parts so as to perform all the above operations one one machine.
The Invention also relates to an improved clutch by which the machine may be
readily put in and out of gear or work.
.
A machine according to this my said Invention comprises a press having solid
bearings. A plate is attached to the bottom of the slide for holding the die or tool.
I also apply a plate with screw adjustment to accomodate the different thicknesses
of metal to the bed plate or plate on which the metal to be operated upon is placed,
or the punch or pressure tool may be adjustable so as to place the work nearer to or
further from the punch or pressure tool.
The slide I raise by means of a weight, the downward motion being obtained by
cam or eccentric, or a cam may be employed for giving positive motion to the slide
in both directions. For impressing name, trade marks, or other indentations after
the article is formed in the press I use a die working under the main die.
The bottom of the die or "burring" edge used in the manufacture of flanged
circular covers, bottoms, or ends of cans, kegs, or cylinders, I construct of a ring of
steel, so as to be renewable when worn out. The machine may be moved from the
vertical to an inclined position by means of a segment rack and pinion wheel.
When the machine is being used for working metals giving off scale or refuse a
passage way for escape of the same is provided, the vibration of the machine in
work causing the refuse to pass to and outward by the passage way.
The clutch comprises a pin or key passed through a clutch block; the other end
of the said pin or key acts upon an incline, thereby withdrawing the pin clear of
the boss of the driving wheel, which is thus free to run loosely upon its shaft.
The dies and working parts of the machine are so arranged that the work as
completed may be carried through or lifted out of the dies.
Such being the nature and object of this my said Invention, I will now describe
the same in detail, and in order that the particulars may be fully understood I have
hereunto annexed two Sheets of Drawings fully illustrating the construction and
application of my improvements to machinery as aforesaid.
DESCRIPTION OF DRAWINGS.
Figs. 1, 2, are side and front elevations of machine. At I, I, are solid bearings
or V slides, to the bottom of which the plate 2 is secured, and to the plate 2 is
attached the die plate 3 carrying the die 4; the plates 2, 3, and the die 4 are
adjustable by means of the screws 5, 5; 6 is the bed plate; 7, 7, are the eccentrics
by means of which the downward stroke to the slide and die is imparted, the slide
and die being raised by weight as ordinary. At Fig. 2a is shewn a punch or
pressure tool for "drawing through," adjustable by means of the eccentric 8.
Fig. 3 shows construction of apparatus for impressing name or trade mark or
other indentation on the article after same is formed in the press. Figs. 4, 5,
6, and 7 are details showing construction and application of improved burring
edge or ring. At 9 is the cutting edge, within which is the steel burring
ring 10; 11, a ring or disc which secures the burring edge in position; the disc 11
and burring ring 10 are either or both of them reversible, that is to say, that when
one edge or surface is worn out, may be removed, turned over, and its other surface
employed. Figs. 1, 2, and 2b shew the machine mounted upon fulcrum or hinge
pins 12 and upon segment rack 13 and pinion 14, that the body of the machine

page_text: may be removed from the vertical position to any desired angle (see Fig. 2b), and
secured in such position by lock nuts 15. At 4 and 6 is shewn passage ways 16 for
scale or refuse; the vibration of the machine shakes the scale outward and keeps
the die clear. At Figs. 8 and 9 is shewn the improved clutch. At 17 is a pin or key
working in a slot or groove cut in the swell 18 of the driving shaft 19; the key
passes through the fixed flange 20 and into the recess 21 in the boss 22 of the fly
wheel, the key being shot into the recess after the manner of a bolt by means of the
blade spring 23, but as the wheel revolves the end of the pin or key comes in contact
with the incline 24, which withdraws the key from the recess, leaving the driving
wheel loose upon the driving shaft; so soon however as the wheel revolves again
and its recess 21 is opposite the key 17, the spring 23 will again act and shoot the
key into the recess 21, to be again withdrawn by the incline 24 so long as the
machine is inoperative. When however the dies are to act the workman will by
treadle 25 and connecting rods 26, 26, draw down the incline 24 clear of the key 17,
leaving the latter in the recess and the wheel fast upon the shaft, and the machine
continues at work so long as the incline 24 is kept clear of the key 17. The tool
for cutting blanks simply is shewn at X, Fig. 1; Fig. 2a shews die X for cutting
and forming, and passing through; Fig. 2b shews die X' and spring barrel X2, by
which the operations of cutting, forming, stamping, and passing outwards through
the die, the spring barrel is secured by bolts X3, X4, and flange X³, when the
bolt X is loosed the barrel may be swung on the bolt X* clear or away, so that the
work may pass through.
Having thus fully described the nature and particulars of this my said Invention,
I would have it understood that I claim as my Invention,-
Firstly. The reversible burring edge or ring 10 in combination with the disc 11
for the purpose and substantially as illustrated and described.
Secondly. The use in combination of the pin or key 17, incline 24, and spring 23,
acting in a manner and substantially as described.
Thirdly. I claim the use in combination of hinge joints 12, 12, segment rack 13,
and pinion 14, for purpose aforesaid, whereby machines for purposes aforesaid may
be used in a vertical or an inclined position, as described and illustracted.
In witness whereof, I, the said Frederick J. Taylor, hath hereunto set my
hand and seal, this Second day of June, in the year of our Lord One
thousand eight hundred and seventy nine.
