and the other movable to or from the stationary block by means of a screw and hand
wheel or by other suitable mechanism. On the top of the movable block is a plate
fixed to the bed of the machine which prevents the block rising as it is moved to
and fro or to this end the block and the groove in which it slides may be dove-
tailed or otherwise formed. Between these two blocks which I call the link
holding blocks I provide a third block which I call the stud block and which is
shaped so as to fit inside the link and has a cross groove on its upper face for
the stud to rest in. The said stud block is furnished with a shank fitting loosely
in à longitudinal slot in the bed of the machine so that it can move to and fro
through a short space in the same direction as the movable link holding block.
The ends of the said stud block are hollowed so as to clear the link or links
which are connected to that link into which the stud is being fixed and at each
side of the bed of the machine is a V or other shaped groove in which the chain fits
whilst the link is being operated upon.

the fixed block so as to grip the heated link and squeeze its sides together so as
to firmly grip the ends of the stud. The sliding block is then withdrawn from
the chain which latter can then be removed ready for the next link to be operated upon.
The stud holding block is preferably made to slide as above described so that it
can accommodate itself to the motion of the link while the stud is being closed
thereon and thereby the better enable the finished link to be removed.
Instead of making the stud holding block movable as above described it can be
fixed and both of the link holding blocks arranged to slide which can be accom-
plished by each of them being provided with a screw and the said screws being
geared together by a shaft underneath the machine and by spur wheels or other
means so that the link holding blocks will move together to or from the stud
block for the purpose of closing the link against the ends of the stud or allowing
of the removal of the chain as above described.

COMPLETE SPECIFICATION.
Improvements in Machinery for Making Stud Chains and Stud
Chain Cables.
I, CALEB WOODHOUSE, of New Town Lane, Cradley Heath, Worcestershire, Chain
Manufacturer, 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 :-
This invention has reference to improvements in machinery for fixing studs in the
links of crane and other stud chains and stud chain cables, the object being to enable
the said chains and chain cables to be made more quickly and with greater accuracy
than heretofore.
On the accompanying drawings Fig. 1 represents in longitudinal sectional elevation,
Fig. 2 in cross section, and Fig. 3 in sectional plan, a machine constructed according
to this invention for making stud chains and stud chain cables: Fig. 4 represents the
stud block (forming a part of the said machine) separately; Figs. 5 and 6 shew how
the machine operates to fix a stud in a chain or chain cable link.
The same letters of reference indicate the same parts in all the Figures of the
drawings.
The links of the chain are marked a and the studs are marked b. In carrying out
my invention I provide a cast iron bed c by preference of the shape shewn, to support
the various parts of the machine, which may have lugs ce for fixing the bed to a
bench or other support, and I provide two link holding blocks did each of which is
shaped at e so as to fit round nearly half one of the links of the chain. These blocks
rest on the bed c of the machine and fit in a longitudinal groove therein, the block d¹
being stationary and the other block 2 movable to or from the stationary block d¹ by
means of the screw 9 passing through the stationary nut and provided with the
handle or other suitable mechanism may be used to move the block d² to or fro as
will be readily understood. On the top of the movable block is the plate j fixed to
the bed of the machine by screws k k so as to prevent this block rising as it is moved
to and fro, and the stationary block is similarly secured by the plate ; or to this
end the block d² and the groove f in which it slides may be dovetailed or otherwise
formed. Arranged centrally between the two blocks did I provide a third block m
(shewn separately by Fig. 4) which I call the stud block and which is shaped so as to
fit inside the links a and has the cross groove n on its upper face for the stud b to
rest in. The stud block m is furnished with the shank o fitting loosely in the longi-
tudinal slot in the bed c of the machine, so that the stud block m can move to and
fro through a short space in the same direction as the movable link holding block d'.
The ends of the stud block m are hollowed so as to clear the link or links which are
connected to that link into which the stud is being fixed and at each side of the bed c
of the machine is the V or other shaped groove in which the chain fits whilst
the link is being operated upon.
The machine above described is used as follows:-The link a into which the stud b
is required to be fixed is heated and placed in position between the two link holding
blocks d' d², and the stud is placed on the groove n in the stud block m (see Fig. 5).
The sliding link holding block 2 is now moved towards the fixed block d¹ by turning
the handle i so as to grip the heated link a and squeeze its sides together so as to
firmly grip the ends of the stud (see Fig. 6). The sliding block d' is then withdrawn
from the link by turning the handle i in the opposite direction and the link is then
removed ready for the next link to be connected to it. The stud holding block m
is made to slide as above described so that it can accomodate itself to the motion
of the link while the stud is being closed therein and thereby the better enable the
finished link to be removed.
It will be seen that the machine above described ensures the studs being fixed in

page_text: the links in their correct position and finishes all the links to the same shape and
size.
The accompanying drawings illustrate what I consider to be the best way for
carrying my said invention into effect but it is to he understood that I do not limit
myself to the precise details illustrated.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. In machinery for fixing studs in stud chains and stud chain cables, a pair of
blocks, suitably supported and adapted for holding and squeezing the sides of a
chain or chain cable link against the stud and for releasing the link in combination
with a third movable block adapted for supporting the stud in position meanwhile,
substantially as herein before described.
2. A machine for fixing studs in stud chains and stud chain cables constructed
arranged and operating substantially as herein before described and illustrated by the
accompanying drawings.
