13mm Patent No. 86,789, daad Fama/ry 9, 1869.
IMPR-OVEMIENT IN MOULDERS RIDDLE.
`The Schedule referred to in these Letters etent and making part of the Isaule.
' c-forn-- To all 'whom it1 'ma/y concern:
'ence being had to the accompanying drawings, forming part of this specification, in Which- Figure l is a top View of our improved riddle, part of the hoops being broken away to show the construction.
Figure 2 is a cross-section ofthe same,.taken through 'the line :c x, iig. l.
Similar letters of reference indicate like parts.
Our invention has for its object to furnish an im proved riddle for moulders use, Simple in construction, strong, and durable, not liable to break, and not liable to burn out when used to receive and screen hot metal; and v It consists in the construction and combination of the various parts of the riddle, as hereinafter more fully described.
A is the main band or hoop ofthe riddle, to the lower part of which the wire cloth or screen -B is attached.
The hoop A is made of sheet-metal, and the wire cloth B is secured to it, by passing the wires of' said wire cloth through a row of holes formed through the said hoop, near its lower edge, as shown in iigs. l and 2.
The upper edge of the hoop A may be strengthened by turning 1t outward over a wire, as shown in iig. 2, and its lower edge may be strengthened by turning it inward over a Wire, as shown in fig. 2.
G is a Wooden hoop, placed around the lower part of the hoop A, so as to cover the wire of the screen B, that projects upon the outer side of said .hoop A, and at the same time, and especially, to form a part of the riddle that may be a non-conductor of heat, so that the operator may'hold the riddle in his hands when screening hot metal, or other hot Substances, Without being liable to be burned by the riddle becoming hot.
Riddles, when madein this way, are not only Stronger, and more durable, but also, wh en the wire cloth or screen B may become Worn out, or be broken, it may be ref newed at a comparatively small expense.
As the wires of the screen project upon the outer side of the metallic hoop A, they would prevent the hoop G from iitting closely to the outer side of the hoop A. To remedy this', the wooden hoop C may be made with a shoulder or oiset upon the lower part of its inner side, or, which is the preferable construction, a thin extra hoop, D, may be placed between the upper part of the Wooden hoop C and the metallic hoop A, of such a thickness as to equal or a little exceed the projection of the wires of the wire cloth B, as shown in g. 2.
The wooden hoop G may be secured to the metallic hoop A by rivets, so as to make the riddle rrn, and prevent thehoop C from working upon the hook A.
Having thus described our invention,
We claim as new, and desire to secure b'y Letters Patent- The moulders riddle, consisting of the hoop A, wire cloth B, and wooden hoop C, constructed, combined,J
and arranged as herein described.
JAMES '0. WARD. JOSEPH HUDSON.
