Description
f@ toege@ JOHN OWEN, or DAYT'oN, omo, AssIGNoR rro HIMsELF, HENRY L. BROWN.' AND A. BARR IRWIN, OF SAME PLACE.
t Letters Patent No. 84,438, dated November` 24, 1868.
IMPROVEMENT IN PATTERNS FOR STOVES AND HOLLOW WARE.
The Schedule referred to in these Letters Patent and making part of the' same.
To all whom ztmay concern:
Be it known that I, JOHN OWEN, of Dayton, in the county of Montgomery, and State of Ohio, have invented a new and useful Improved Mode of Constructing Patterns for Gastin g Stoves,' Hollo.v Ware, Ste.; and I do hereby declare that the following is a full, clear, and exact description ot' the same, reference being had to the annexed drawings, making part of this specilication, in which- Figure 1 is a plan,
Figure 2, an elevation of a pot-pattern.
Figure 3, an elevation showing the mode of constructing the pot-patterns, and
Figure 4 is a section ofthe stove-plate pattern.
The same letters in all the figures are used te indicate the same parts.
My invention consists in constructing patterns for casting stove-plates and hollow ware from paper, as set forth in the following specification.
Stoves an'd hollow ware are, ordinarily, east from iron patterns. These patterns are cast from others, made of Wood. As it is desirable that the plates should be thin, the wood must of 'course be cut down to the requisite thinness. This operation is performed by hand, and is very expensive. The wooden patterns thus constructed, when placed in the sand, in forming the mould, become damp, and when removed they are liable to warp, and be consequently spoiled. Besides this, being composed of many' pieces, they are liable to be split or broken 'in rapping them, in order to draw them from the mould. The wooden patterns of pots are composed, necessarily, of' a great number of pieces glued together, and are both expensive and fragile.
In order to remedy these objections to the wooden patterns heretofore required, I have substituted sheets of paper, which may be made of-Whatever thickness it is desired to have the patterns.
The stove-plate patterns, A, iig. 1, being cnt to the requisite form, are of a uniform thickness. Fillets, B, being cut to the desired form, are attached to the edges of the plate by glue, to make whatever edges or rims may be desired, and when completed, the whole is coated with varnish.
To make the patterns for the hollow ware, Iirst make a block or former, of the required internal size. Around this I place a conical sheet of paper, having the edges glued together, of the size and shape of the top of the pot. The bottom is formed by cutting out triangular pieces from the small end of the paper cone, so as to leave points, which, when folded down over the block, will close their edges, one against the other, forming a rounded bottom for the pot, of the exact form ofthe block. The edges thus matched are glued together, and the whole protected by a coating of varnish. p
By this means, I am enabled to produce patterns at a very small percentage ofthe ordinary cost of wooden patterns, and which have been found,`on trial, tol be superior, as not being aiiected by the dampness of the sand, nor liable to crack or warp from climatic influences.
What I claim as my invention, anddesire to secure by Letters Patent, is-- Patterns, for casting stove-plates and hollow ware, made of paper, substantially a's setforth.
In testimony whereof. I have signed my name to this specification, in the presence of two subscribing witnesses.
Witnesses:
. J. P. CoNxILIN,
ASHLEY BROWN.
JOHN OWEN.
