Improvements in Machines for Punching, Slotting, Nibbing,
Trimming, and Straightening Camber Spring Plates.
We, JOHN SEAMan Pessenger, Engineer, of 1165 Fulton Street, Brooklyn, New
York, and GEORGE HASELTINE, Counsellor at Law, of 247 Broadway, in the City and
State of New York, United States of America, do hereby declare the nature of this
Invention to be as follows:-
The said invention is designed for use in connection with the Spring Fitting
Machine, patented the 30th day of January A.D. 1885 No. 1335, but is equally well
adapted for preparing spring plates which are to be fitted by hand.
This machine at one operation punches, slots, nibs, trims and straightens the plates
preparatory to fitting them by hand or by a machine.
The frame of the machine is preferably made of cast iron. The bed-plate and
uprights for supporting the shafts are in practice cast together. Upon the top of the
frame are two tables parallel to each other secured to said frame.
The inside table may be cast as part of the frame but the outside one is preferably
bolted to said frame. Upon the top of the outside table are three lugs cored and
provided with screw threads into which screws work, and it also has two V grooves
formed therein.
The machine is provided with three parallel shafts which are supported on suitable
bearings on said uprights. The driving shaft carries a tight and loose pulley, and a
gear wheel keyed to its end.
On the next shaft is secured a larger gear wheel which works into said gear wheel
on the driving shaft. A crank is cast upon the web of said large gear wheel and is
provided with a crank pin on which the connecting rod works. The said rod is
secured to the end of the actuating lever which is located in the centre of the machine
and gives motion to its working parts. Through this lever the working shaft runs
and is keyed thereto. The said shaft runs parallel to the driving shaft across the
entire top of the machine and is supported by four hearings upon said uprights, one
at each end, and one at each side of said actuating lever. Secured to the working
shaft are the actuating lever, two cranks and three cams. The said lever gives the
working shaft a quarter turn or rock motion, operating the cranks and cams.
A tool post is formed on the short end of the lever and on each crank each post
being provided with a clutch for supporting the various tools for the aforesaid
purpose.
The said cranks are secured to the working shaft by a key-way formed upon the
shaft and the hub of each crank. A feather key is secured to the shaft and with a set
screw secures the cranks and allows them to be moved inward or outward from the
centre to the desired distance apart to operate on long or short plates.
The three cams are secured on the working shaft one at the centre and one near
each end.
Across the top of the machine and parallel to the actuating shaft, is a clamp fitting
into the V grooves formed in the side table which clamp is provided with three steel
rolls, one at each end and one at the centre, against which rolls said cams work and
give a grip for straightening the plates edgewise. This clamp is brought back by
spiral springs attached to the frame and to said clamp.
Opposite the moveable clamp and parallel to it is a stationary clamp the two
forming a grip between which the steel plates are clamped. The stationary clamp is
adjustable inward and outward-and moves upon said V grooves, and to this clamp is
secured the centre vice screw that works into the screw thread formed in the lug on
the table below for moving the clamp to adapt it to various widths of steel plates:
Against this clamp the other vice screws act as supports.

page_text: A movable guage is secured to the top of this outside clamp for stopping plates at
any desired distance.
Between the two tables below the clamps and formed on them are the die seats that
run entirely across the top of the tables. Into this recess between the tables the
various dies are placed and each is secured by a bolt and eccentric lever to the bottom
of the tables. These dies are adjustable from the centre to the outside of the machine
to adapt them to various lengths of spring plates.
The machine may be used for other purposes but is especially designed for use in
the manufacture of camber springs. The advantages of this machine in such manu-
facture are obvious. The work being performed at one operation the plates may he
fitted and remain in good condition for tempering without reheating. The quality of
a spring plate thus prepared is improved at less cost of manufacture.

COMPLETE SPECIFICATION.
Improvements in Machines for Punching, Slotting, Nibbing,
Trimming, and Straightening Camber Spring Plates.
We, JOHN SEAMAN PESSENGER, Engineer, of 1165 Fulton Street, Brooklyn, New
York, and GEORGE HASELTINE, Counsellor at Law, of 247 Broadway, in the City and
State of New York, United States of America, do hereby declare the nature of this
invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The said Invention relates to a machine for preparing camber spring plates for the
fitter, and consists in so constructing and arranging the working parts that the plates
are straightened, punched, slotted, trimmed, and nibbed at one operation of the
machine.
In the accompanying drawings, forming a part of this specification,
Figure 1 is a plan view of the machine; Figure 2 a transverse section on line x, x,
Figure 3 a side elevation and Figure 4 an end elevation.
Like letters refer to corresponding parts in the several figures.
The bed plate A of the machine is formed of cast iron and the other parts of cast
iron and other suitable metals. The sides B of the frame are secured to the base,
which also supports the bearings O. A driving shaft D, carries the tight and loose
pulleys E, E. A small pinion F is secured to the end of shaft D and this pinion
drives a large spur gear wheel F', which is secured to shaft G, and on the face of said
wheel a crank H is secured as shown in the drawings. A connecting rod I is secured
to crank H and to a centre operating lever K, the latter being secured to rock shaft L,
which runs across the top of the machine and is supported on four bearings m one at
each end and one each side of the centre lever. Tool posts N, N1, for holding suitable
tools for punching, slotting and nibbing the plates are secured to rock shaft L, the
tool post N being fixed and the posts N₁ being adjustable on said shaft. Keyways are
formed upon the top and bottom of rock shaft L, in which keys or feathers are placed
and which with stud bolts P secure cranks or levers Q to the said rock shaft, and
upon the outer end of cranks Q are clutches R for holding the various tools for
punching, slotting, and nibbing the spring plates. These clutches are made moveable
inward and outward to adapt the machine to operate upon plates of different lengths
and widths.
Grips S are secured at each end of rock shaft L inside the outer bearings and also
in the centre of said shaft, which grips impart motion to grip clamp T; the latter
runs across the top of the machine in V grooves U, and parallel to said clamp T is a
clamp T which runs in groove U₁. The grip clamp T' is operated by three screws V,
the centre one of which is fixed to the clamp for the purpose of moving the same
inward and outward to adapt the machine to operate on plates of various widths,

page_text: An adjustable stop or gauge W is secured upon the top of clamp T at the left as
shown in the drawings, the object being to stop the plates at any desired point. Die
seats X are located across the machine between the clamps T, T¹, said seats being
adapted to receive dies Y of various sizes, which are secured by a bolt and eccentric
lever Z to the under side of the die bed These dies are moved inward and outward
in line with the tool posts above them to keep them in the proper position to operate
upon the plates.
The operation is as follows:- The plates being removed from the furnace, are
presented to the machine at the right side when levers K and Q are in position shown
in Figure 3. The clamp T is drawn back as shown. The clamp T then moves
forward and straightens the plate edgewise. The tool posts N, N', move forward and
the plates are punched, slotted, and nibbed at one revolution of the machine. The
parts are then brought into their original position and the plate is removed from the
machine ready for the fitter.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First. The tool posts N, N³, arranged upon shaft L, the posts N being adjustable
upon said shaft for the purpose and substantially as specified.
Second. The cranks or levers Q secured to shaft Land provided at their ends with
moveable clutches R, for the purpose and substantially as specified.
Third. The grips S secured to shaft L in combination with movable clamp T for the
purpose and substantially as specified.
Fourth. The adjustable clamp T¹ in combination with grips S and clamp T for
the purpose and substantially as specified.
Fifth. The dies Y secured in seats X, the two outside seats being adjustable for the
purpose and substantially as specified.
Sixth. The use of an adjustable gauge to ensure the placing of spring plates in the
proper position to be acted upon by suitable tools, substantially as specified.
Seventh. The improved machine for punching, slotting, nibbing, trimming and
straightening spring plates, constructed and operating substantially as specified.
