Improvements relating to Joints for Nut Crackers and the like.
I, WILFRED LAWSON BULLOWs, of the Firm.of Alfred Bullows and Sons, of Long
Street, Walsall, in the County of Stafford, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This Invention consists of improvements relating to joints for nut crackers and
the like, my object being to dispense with the use of the ordinary rivet or joint
pin and to produce an efficient joint at small cost.
In constructing a pair of nut crackers in accordance with my invention I form
the two limbs from any suitable metal preferably by casting, making them of any
required design or configuration. After preparing the moald in the ordinary
manner for the reception of the molten metal I place within the same a square loop
or shackle, formed preferably from iron or other wire of a circular section, in such a
position between the ends of the limbs to be jointed, that when the metal is run
into the mould it surrounds two opposite sides of the shackle which thus becomes
cast with the limbs, and forms a connection joint between them. Before insert-
ing the loop or shackle in the mould we treat it with oil or grease or other suitable
sustance to prevent the adherence of the cast metal.
Instead of casting in the loop or shackle as herein before described, we sometimes
cast an open jaw on each limb, which are afterwards closed over en to opposite sides
of the loop or shackle.
By this our improved construction we are enabled to readily produce at small
cost a free working hinge joint without the rivetting nd fitting operations
required with the ordinary methods of construction..

I, WILFRED LAWSON BULLOWS, of the Firm of Alfred Bullows and Sons, of Long
Street, Walsall, in the County of Stafford, Manufacturer, do hereby declare the
nature of this invention and in what manner the same is to le performed, to be
particularly described and ascertained in and by the following statement:-
This Invention consists of improvements relating to joints for nut crackers and
the like, my object being to dispense with the use of the ordinary rivet or joint
pin, and to produce an efficient joint at small cost.

page_text: In the accompanying sheet of explanatory drawings to
referred to:-
hereinafter
Figure 1 is an end elevation, Figure 2 a side elevation, and Figure 3 a plan of a
pair of nut crackers made in accordance with my invention.
Figure 4 is a plan of the jointing shackle to a larger scale.
The same reference letters in the different views indicate the same parts.
In constructing a pair of nut crackers in accordance with my invention I form
the two limbs A A' from any suitable metal preferably by casting, making them
of any required design or configuration. After preparing the mould in the
ordinary manner for the reception of molten metal I place within the same a
square loop or shackle as B, formed preferably of iron or othe wire of a circular
section, in such a position between the ends of the limbs to be jointed, that when
the metal is run into the mould it surrounds two opposite sides of the shackle which
thus becomes cast with the limbs, and forms a connection joint between them.
Before inserting the loop or shackle in the mould I treat it with oil or grease or
other suitable substance to prevent the adherence of the cast metal.
To make the joint work more freely and smoothly, I place a small open jointed
or other tube or roller as C on each side of the shackle as illustrated at Figure 4
(where the tubes are shown in section,) before its insertion within the mould. The
molten metal will then seize on the exterior surface of each tube but the interior
surfaces will form smooth bearings for the jointing shackles.
Instead of casting in the loop or shackle as hereinbefore described, I sometimes
form an open jaw on each limb, which jaws are afterwards closed over on to
opposite sides of the loop or shackle.
By this my improved construction I am enabled to readily produce at small cost
a free working hinge joint without the rivetting and fitting operations required
with the ordinary methods of construction.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what
I claim is.-
1. The improved method of jointing nut crackers and the like without the use of
an ordinary rivet or joint pin substantially as described.
2. Nut crackers having their limbs connected with a jointing shackle
substantially as descabed and as illustrated.
Dated this 29th day of May 1897.
