Description

Mnrrnn PORTER W. SHIMER, OF EASTON, PENNSYLVANIA.

CRUCIBLE SPECIFICATION forming part of Letters Patent No. 669,862, dated March 12, 1901.

Application iiled'September 22, 1900. Serial No. 30,754. (No model.)

T0 @ZZ whom it may concern.-

Be it known that I, PORTER W. SHIMER, a Citizen of the United States, and a resident of Easton, in the county of Northampton and State of Pennsylvania, have invented a new and Improved Crucible, of which the following is a full, clear, and exact description.

The invention relates to combustion-crucibles such as shown and described in the Letters Patent of the United States No. 653,823, granted to me on Julyl', 1900, and mainly used for fusing or highly heating metal or other substance in an atmosphere of any gas desired, the crucible being provided with a hollow stopper seated on a rubber gasket and having means for Cooling the stopper and Crucible and circulating air or other gas through the latter.

The object of the invention is to provide a new and improved Crucible having means for more effectually cooling the upper end of the stopper to prevent the rubber gasket from being burned or otherwise injured while the crucible is used.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the Claims.

Figure l is a perspective View of the improvement. Fig. 2 is a sectional side elevavation of the same. Fig. 3 is a sectional plan view of the same on the line 3 3 in Fig. 2, and Fig. 4 is a perspective View of a separable cooling-chamber for the Crucible.

The Crucible A, constructed of platinum or other suitable metal, is adapted to receive at its upper end a gasket B, of rubber or other suitable material, and on this gasket is adapted to be seated a hollow stopper O, having airinlet and air-outlet pipes D D' for establishing a circulation of air in the crucible when the latter is used in the usual manner. The hollow stopper O is further provided with a water-inlet pipe E and a water-outlet pipe E', of which the former is connected with a suitable cooling medium supply, such as water, to circulate the water in the said stopper, the overflow of the water passing through the outletpipe E and a flexible connection F to a pipe G,

leading to aCooling-chamber H, arranged eX- ternally on the upper end of the crucible Aand either constructed integrally therewith, as illustrated in Fig. 2, or in the form of a separable hollow ring H', as illustrated in Fig. 4. The chamber H is provided with an outletpipe I, located diametrically opposite the iulet-pipe G.

By the arrangement described the gasket B is located between the hollow cooling-stopper O and the hollow chamber H, so that when the Crucible is used the said gasket is protected from injury by the heat incident to the use of the Crucible7 it being understood that the same cooling medium that is used for the y stopper is used in the chamber H, and consequently the construction of the crucible is simplified as much as possible.

Having thus fully described my invention, I Claim as new and desire to secureby Letters Patentl. A Crucible having an internal gasket, an external coolingchamber arranged approximately opposite the Crucible gasket, and means for circulating a c ooliug medium through said chamber, as set forth.

2. A Crucible having a cooling-chamber at its open end, a hollow stopper, and means for establishing communication between the interior of said stopper and `said chamber, to circulate a cooling medium through the same, as set forth.

3. A Crucible having a cooling-chamber at its open end, a removable hollow stopper, and means for circulating a cooling medium through said stopper and from the latter through said chamber, as set forth.

4. A Crucible having a hollow stopper, a cooling-chamber on said Crucible at its open end, agasket interposed between said hollow stopper and said chamber, and means for circulating a Cooling medium through said stopper and said chamber, as set forth.

5. A Crucible having a hollow stopper, a cooling-chamber on said Crucible at its open end, a gasket interposed between said hollow stopperand said chamber, means for connecting said stopper with said chamber, means for circulating a cooling medium through said In testimony whereof I have signed my name to this specification in Ihe presence 0f nwo subscribing Witnesses.

stopper, the overow of the cooling medium passing by said connecting means into said chamber, and an outlet for the cooling medium from said chamber, as seb forth. l PORTER W. SHIMER.

6. A erueble having a cooling-chamber at its open end, a hollow stopper, and a gasket between the stopper and the cooling-chamber.
