An Improved Machine for Making and Fitting Springs.
J RICHARD BERRY Junior, of the Firm of Richard Berry & Son,
Australian Works, Alma Street Aston, Birmingham in the County of Warwick
Manufacturer, do hereby declare the nature of the said invention as communicated
to me from abroad by Charles Lewis of the Firm of Lewis & Allen of Jackson
Mich. United States of America, Carriage Wagon, Truck, and Seat Spring
Manufacturers, to be as follows:
1
My invention has for its object an improved machine for making and fitting
springs which enables the springs to be formed easily to a variety of forms in the
same machine where they are also put together and tempered with considerable
speed and accuracy.
The principle portion of my invention consists of the holster or mould and the
reciprocating press which acts upon the spring against the bolster. The bolster is
composed of a series of fingers or strips placed upon a suitable base plate so that any
of them may be brought forward or backwards so that the points of a number of them
forms the back configuration of the spring or one of its parts or layers. The
points of the fingers are rounded and the back ends are recessed to receive a coiled
spring which is inserted and projects at the end thus forming a sensitive spring
bolster and they may be packed up against the abutment flange on the base plate
to any desired extent and they are exchangable for larger or smaller ones to suit
any sized springs. The reciprocating press pait or head is supplied with a number
of set bolts or pins with more or less rounded heads which may be screwed inwards
or outwards to agree with the configuration of the bolster for the time being and
the pins are locked with lock nuts the head is reciprocated by a shaft carrying an
eccentric block or crank driven by geared wheels from a suitable driving shaft.
separate eccentric is also mounted upon the driving shaft to which a foot or other
brake is attached to retard the action of the reciprocating head in its return movement
to counteract the thrust of the bolster springs. The foot pedal is also connected
with an engaging gear on the main shaft for starting and stopping the
motion at any time. This brake may continue under the machine so
be worked by an operative at the front or back of the machine but it will be
evident that this arrangement may be varied to suit the design and position of
the machine.

I, RICHARD BERRY Junior, of the Firm of Richard Berry & Son, Australian
Works, Alma Street, Aston, Birmingham, in the County of Warwick, Manu-
facturer, do hereby declare the nature of the said invention as communicated
to me from abroad by Charles Lewis, of the Firm of Lewis & Allen, of Jackson,
Mich., United States of America, Carriage, Wagon, Truck and Seat Spring
Manufacturers, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My invention has for its object an improved machine for making and fitting
springs which enables the springs to be formed easily to a variety of forms in the
same machine where they are also put together and tempered with considerable
speed and accuracy.
The principle portion of my invention consists of the bolster or mould and the
reciprocating press which acts upon the spring against the bolster. The bolster is
composed of a series of fingers or strips placed upon a suitable base plate so that
any of them may be brought forward or backwards so that the points of a number
of them forms the back configuration of the spring or one of its parts or layers.
The points of the fingers are rounded and the back ends recessed to receive a
coiled spring which is inserted and projects at the end thus forming a sensitive
spring bolster and they may be packed up against the abutment flange on the base
plate to any desired extent and they are exchangable for larger or smaller ones to
suit any sized springs. The reciprocating press part or head is supplied with a
number of set bolts or pins with more or less rounded heads which may be screwed
inwards or outwards to agree with the configuration of the bolster for the time
being and the pins are locked with lock nuts the head is reciprocated by a shaft
carrying an eccentric block or crank driven by geared wheels from a suitable
driving shaft.
A separate eccentric is also mounted upon the driving shaft to
which a foot or other brake is attached to retard the action of the reciprocating
head in its return movement to counteract the thrust of the bolster springs. The
foot pedal is also connected with an engaging gear on the main shaft for starting
and stopping the motion at any time. This brake may continue under the machine
so as to be worked by an operative at the front or back of the machine but it will
be evident that this arrangement may be varied to suit the design and position of
the machine. The portions or layers of the spring are heated in a furnace and are
brought together in the machine and are bolted together, and while in position
are tempered by a suitable arrangement of water pipes.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto two double sized drawings in which
I have illustrated one example of the machine showing a spring therein in process
of manufacture and will be manifest from the following explanation that other
forms of springs may be made in the same machine by adjusting the parts
thereof.
Figure 1. is a side elevation of the machine in its condition ready for working.
Figure 2. is a plan of the machine shown by Figure 1.
Figure 3. is an elevation of the right hand end of the machine.
Figure 4. is a plan of one of the fingers a' forming the bolster or mould.
Figure 5. is a sectional elevation of Figure 4 on line 5. 6.
Figure 6. is an elevation of the right or spring end of one of the fingers.
On reference to the diawings S Figure 2 represents portions of a spring in
course of manufacture, I being the template, 2. a portion or layer of the spring
already complete and cool, and 3 the portion or layer now being bent and

page_text: hardened. The bolster plate A rests on the bed plate M which is common to the
whole machine, and m' are abutment snugs or stops for the bolster A but at
present the packing piece a³ is used and may be of any thickness thickness to suit
the work in hand. Upon the bolster plate A a series of fingers or strips a¹ are
mounted having heel springs a² which abut against the flange a³ of A or
intermediate blocks a* may be also used so as to bring out the curved points of the
fingers a¹ so as to form any desired configuration of bolster front.
These finger
pieces are shown in detail by Figures 4 & 5 & 6. and may be made any depth to
suit the width of spring to be made. The moving portion or slide B carries a
series of set pins 1, with lock nuts, b³, these pins being tapped into suitable holes
in the slide B as shown. The angle pieces b may be moved outwards or inwards
so as to deal with longer or shorter springs and the front part of B may be
removed altogether and exchanged by the bolts and snugs & on the slide B for
other front pieces. The water pipes Y with taps y are arranged conveniently to
the operator or operators for cooling the part in hand, say part 3 which is the
one now being formed and hardened the end of the pipe Y being held by the
operator in such a manner that the water is directed on to the part 3 whilst
the latter is in position as shown by the plan Figure 2 and the tank or trough D
receives the water as it drains away from the bolster. The slide B is operated
as follows: The flywheel and driving pulley F is mounted upon the driving shaft
carried upon the bed plate M and having a fast pinion thereon which gears into a
spur wheel Z which runs loose on the secondary shaft. This second shaft also
carries the main driving eccentric R which operates against the friction roller 6³
which is hung in the slide B & the slide is thus moved forward bringing the heads
of the set pins 61 against the template 1 of the spring S. At the utmost throw of
the eccentric there may be a slightly flattened or hollowed part to make a better
bearing against the roller 63 for the final thrust. The slide B is brought back by
means of the balance weight W and chains w¹ and w² which are attached
underneath the slide B. The second eccentric V is controlled by the brake T
hung upon the pivot t' and pressed down by a measured pressure by the springs t²
and by this means the slide B is prevented from returning too rapidly by the
recoil of the springs a². The spur wheel is made fast with the second shaft or
brought into gear by the lever L operating upon the clutch C which is clearly
shown and the lever is operated by the pedals P from several positions around the
machines. The pedals are hung to the Jaws H and the connection with the
lever L is by means of the chain . The mechanism for working the slide B may
of course he largely varied to give and control the necessary reciprocating motion
and the design and arrangements of parts may also be varied considerably.
Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is :-
1st. The improved machine for making and fitting springs substantially as
herein set forth and as illustrated upon the drawings by Figures 1, 2, 3, 4, 5
and 6.
2nd. The bolster A composed of a number of adjustable finger pieces a¹ with
the mode of adjustment to various curves in combination with the sliding
bolster B and adjustable parts to be operated by any convenient mechanism
substantially as herein set forth and shown.
