MPROVEMENT iN CASTING TEA-POT SPOUTS ND HANDLES.
Speciticntion forming part oi Letters Iatent No. 13,695, dated October 16, 1855.
To @ZZ whom it may concern:
Be it known th at I, Ti-rnononn AOKERMAN, of Cincinnati, Hamilton county, Ohio, have invented a new and Improved Method of Casting the Spouts and Handles of Tea-Pots; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the annexed drawings, making part of this specification.
This invention has reference to the casting the usual hollow trimmings of britannia and other like ware,which, being fusible over an open tire, is cast in a mold ot' more refractory metal, the melted stock being, as is well known, retained sufficiently long wit-hin the mold for a portion to congeal and i'orm the desired hollow casting.
The method of casting tea-pot sponts, patented December l2, 1854, to Tribe, Muhle, and Homan, has been until a recent date very extensively and profitably employed by me, in eonj unction with the patcntees, in Ithe manufact-ure of britaImia-ware. The process, although far superior to the common method in accuracy, tacility,and dispatch, has been t'ound subject to occasional detects and hinderances.
Among these are trouble and expense of a ire ior heating the cope; liability to overheating of said cope, and consequent rounding oft' and deficiencies in the margin ot' the spout; delay in waiting to cool after overheatingI` of cope; insuicient heating ot the cope, so as to result in the formation ot' a spine beyond the proper margin of the spout; time expended in waiting for and watching the proper heating of the cope.
The above defects, incidentto the really valuable invention before referred to, are entirely overcome by my plan, as follows:
Figure l is a perspective view of the cope of the handle-mold. Fig. 2 is a perspective view of the cope employed to i'orm the base of the spout. Fig. 3 represents one part of the handle-mold and a sectional view of the applied cope. Fig. represents one part of the spout-mold, the cope being in section. Fig. 5 represents by section the spout-easting previous to removal from the mold.
As respects the form of spout-mold and of the metallic portion of its detachable cope, (which supplants the older sprue-gate,) the construction and arrangement are similar to those ot' the patented device before referred to, with this exception, that the metallic hollow or interior surface of the cope is madeto correspond in size and form with the desired hollow of the spont-that is, ther tact with the stock imparts to the base ofthe spout a sharp, well-delinededge of exactly corresponding thickness and contour, because all of the stock which ilows against the slowly heat-conducting lining runs ott' with the rest ot' the unappropriated stock. By this means there is given to the casting, without any de lay or uncertainty, a margin closely adapted to the pot-body and requiring the least possible amount of solder, and there results a strong, cheap, quickly made, and invisible joining7 The nozzle ofthe spout, here represented with a common sprne, g, may be formed on my improved plan.
l@ is one of the parts of a handle-mold, and is so arranged that both joinings of the handle are formed on my plan. The two copes ij are joined permanently one to the other by a brace, It', so as to ret-ain them at a distance and position corresponding to those ot the partingsnri'aces Z m ot the mold. This construction enables both copes to be held in place or lifted at once and by one hand. 'By this simple contrivance the two detachable copes are conveniently handled, and serve by means of the dowels 0 to hold the parts ot' the mold together. The plaster is applied to the copes of the handle-mold' in manner similar to that ot' the spout-mold. Various other non-inetallic substances can be made to supply the place of plaster in this connection.
The process can of course be applied to the l gous object, in the manner and for J@he pun casting of spouts and handles of pitchers or pose described.
other lanalogous objects. In testimony whereof I hereunto set my Vlmt I claim as vnew and ol' my invention hund before two subscribing witnesses.
