Improvements in and relating to Machinery for Making or
Weaving Wire Mattresses.
I, JOHN THORNTON, of Westgate, Cleckheaton, in the County of York, Card
Machine Maker, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to construct machinery for making or weaving
wire mattresses, so as to automatically feed the required length of wire for making
the mattress, and after such feed, automatically cutting off the required length of
wire, also to move each coil, when formed and cut off, into position to receive the
next coil being formed.
Attached to the clutch upon the driving shaft of the machine is a suitable lever
having a notch or inclined plane formed upon it, working within which is a vertical
lever connected to and operated by a suitable slide, fixed upon the side of the
machine frame, this slide is operated at intervals for feeding, and stopping the feed,
by a suitable cam upon a tappet shaft, fixed behind the main driving or feed shaft, so
that when the necessary feed has been given, the tappet moves the slide, which, by
means of the aforesaid levers and clutch, throws the feed rollers out of gear, so
stopping the feed.
While the feed is stopped, the coil just formed is automatically cut off and moved
into position for the next coil to be formed this operation is repeated until the
required width of mattress is obtained.
T'he cutting off mechanism consists of suitable cutters, mounted in slides fixed
at the feed end of the machine, immediately in front of the giraffe, these slides or
cutters are operated at intervals by means of suitable levers, and cam, upon the
aforesaid tappet shaft.

I, JOHN THORNTON, of Westgate, Cleckheaton, in the County of York, Card
Machine Maker, do hereby declare the nature of this invention, and in what
CD Q71

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of my invention is to construct machinery for making or weaving wire
mattresses for bedsteads, furniture seats, and the like, so as to feed the required
length of wire for forming the spirals or coils, after which the said feed mechanism
is thrown out of gear, and the spiral or coil already formed cut off, such spiral is
then moved a suitable distance, so that upon the feed being again actuated, the
spiral being formed interlocks with the spiral or coil last made, and forming part of
the partially manufactured wire mattress, the several movements and operations
taking place automatically, in such a manner that the attendant has only to see
that a sufficient supply of wire is provided upon the wincel, and stop the machine
when the required width of mattress is obtained.
Fig. 1 is a plan view of my improved apparatus for weaving or constructing wire
mattresses for bedsteads, furniture seats, and the like, without the table.
Fig. 2 is a front view of Fig. 1.
Fig. 3 is a side view of Fig. 1.
Fig. 4 is a side view of Fig. 1 showing cams for operating cutting mechanism.
Fig. 5 shows side elevation of table and mechanism for moving the partially
formed mattress, or seat into position for the next spiral or coil.
Fig. 6 is a front view of Fig. 5.
Upon a suitable frame A, I mount a headstock B, upon which is fixed the feed
mechanism, passing through this headstock and supported by bearings or
journals B, is the main driving or feed shaft C, this shaft operates at intervals the
feed mechanisin, which cousists of a pair of feed rollers DE, the bottom roller E
being keyed upon this shaft C, a gear wheel D¹, also keyed upon the driving shaft
operates the top roller D, by gearing with a second gear wheel D², upon the top
roller shaft D3, this feed mechanisin is put in and out of gear by means of i
clutch F, upon the shaft C, operated by a fork G, upon a pivotted carrier G
attached to a lever G2, this lever G2 is operated from a tappet or cam shaft H, upon
which is a tappet or cam H³, this tappet operates upon an antifriction bowl or
projection H2, upon a slide or lever J moving the same forward and as the runner
or projection J¹ attached to the slide comes in contact with the lever G2, it moves
the pivotted carrier G' on its pivot G³, and throws the feed mechanisin out of
gear.
The cutting off mechanism consists of two cross slides K L, mounted upon the
machine, and preferably at right angles to the feed, upon these slides are mounted
cutters M N, these cutters are also operated at intervals by a wedge or cain P,
fixed upon a sliding bar P¹, upon a vertical slide P³, fixed behind the horizontal
slides KL, this sliding bar P¹, is operated intermittently by means of a cam Q,
upon the tappet shaft H, this cam Qoperates a bell crank lever R, one end of
which terminates in a fork R¹, this fork bears upon a cross bar or antifriction
runners P3 attached to the bottom of the vertical sliding bar P¹, a spring P4 returns
the bar into position after being depressed, springs K' L', also return the horizontal
slides K L after cach operation.
The cutting off mechanism may be thrown out of gear, when extraordinary
lengths of wire are required, or for other purposes by means of a clutch S, operated
by sliding bar S¹, and handle S2, mounted upon the side of the headstock B, T is
the wincel containing the wire from which the mattresses or seating are to be
made.
The action is as follows:-As the wire passes from the wincel T, it is passed
through a guide or nipple T¹, to and between the feed rollers D, E, these feed
rollers force the same through a giraffe E¹, which forms the wire into a spiral
or coil E, such spiral or coil passes forward over a guide plate E³, between the
cutters M N on to a suitable table U. upon which it rests; when the spiral or coil

page_text: is of sufficient length, the tappet H' operates the slide J, which in turn by means
of projection or runner J¹, lever G pivotted carrier G¹, fork G, and clutch F,
immediately throws the feed mechanism out of gear, the cam Q then operates
the bell crank lever R, which depresses the sliding bar P1, and the wedge P
bearing against projections or antifriction runners K², attached to the slides
at each side of the said wedge, moves the horizontal slides K L, in
opposite directions, the slide K coming in contact with the pivotted cutter M
imparts to the same a circular traverse or clipping action, immediately cutting off
the spiral or coil the desired length. Or the feed may be stopped by hand, the
lever G2 being extended and a handle G provided, or if desired a treadle lever M¹,
and vertical bar M2, with inclined end may be employed, this inclined end M³,
operating upon the lever G2 for this purpose; a strong spring G³ bearing against
the lever G2, returns the lever and clutch for operating the feed after each cutting
off operation.
By altering the size of change wheel V, any length of coil may be obtained.
The tappet or
cam H¹ being so arranged and formed, that the feed motion is
stopped until the coil has been cut off and moved into position to receive the next
coil, and the cutting off movement does not take place until the proper length of
coil required is obtained.
Immediately the coil is cut it is moved the required distance upon the table
according to the density of the mattress required, (and so that the coil next to be
formed will interlock with the coil last formed), by means of heart tappet W, upon
the tappet shaft H, operating a vertical lever W₁ fixed upon a rocking shaft W2;
upon the other end of this rocking shaft, is one or more vertical levers or connecting
rods X attached to a series of loose lags or bars X', which form in conjunction with
a second series of fixed bars or lags X² the table top; the loose and fixed bars are
arranged alternately. As the tappet W operates the rocking shaft W2 and raises
the loose lags X₁ at one end, a second series of levers Z, rocking shaft Z¹, and
connecting rods Z2, operated by a further cam Z³ upon the tappet shaft H,
simultaneously and quickly moves the said bars or lags laterally or at right angles
to the feed any distance required, the groove in the cam W being widened at one
part to allow of this quick lateral movement otherwise the levers Z would be
inoperative; a vertical plate or rib Z attached to the loose bars X¹ move the
mattress Z³ for the purposes before described.
Immediately the bars X¹ drop or lower, one or more loose rollers ZⓇ mounted in
sliding bearings Z' attached to each end of the table, rests upon the mattress
partially made, and prevent by their weight, the mattress from moving when the
bars or lags take up their original position ready for another spiral or coil being
formed.
A catch wheel and catch or any other suitable means may be employed upon the
shaft or stud of this roller so as to prevent the roller from revolving except in the
same direction as the loose bars.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In machinery for weaving wire mattresses for bedsteads, furniture seats and
the like, the combination with the feed mechanism, of an automatic stop motion,
cutting off, and coil adjusting mechanism the several actions operating automatically
and intermittently for the purposes as set forth.
2. In machinery for weaving wire mattresses for bedsteads, furniture seats and
the like, the use and employment of an automatic stop motion consisting of a clutch F,
operated by fork G, carrier G¹, lever G², projection or runner J', slide or lever J,

feed during cutting operation and movement of the table, substantially as set
forth.
