SPECIFICATION forming 'part of Letters Patent No. 305,675, dated September 23, 1:884.

y Application filed Mayif, 1884. (No model.)

To @ZZ whom, t may concern:

Be it `known that I, JAMES DrLzsnL, `of

Wellsburg, in the countyof Brooke and State of Vest Virginia, have invented a new and usehad to the accompanying drawings, forming apart of this specification, in which- Figure l is a perspective View of my irnproved apparatus. Fig. 2 is a vertical sectional view of the same on the line an w, Fig. 1.

Figs.- 3 and 4 are like views of modifications.

In the manufacture of `glassware-such as goblets, glass dishes, Ste-as soon as each article is finished it is delivered by the workman to a carrier, who takes it directly to the leer or annealing-oven,where it is annealed. It is therefore necessary in glassworks,where such articles are manufactured, to employ a large force of boys for this purpose, and during the handling of the glassware, as it leaves the nisher and is carried to and placed in the leers, quite a large percentage of the articles are broken.

It is the object of my invention to provide a suitable receptacle in which there shall be maintained a degree of heat sufficient to prevent the glassware from cooling rapidly, which receptacle is portable, so that after it has been filled with the finished articles by the finisher it may be carredto the leers and placed therein without removing or handling the glassware, thereby obviating the carrying of each article separately, and the consequent handling, by which so many are broken.

I will now describe my invention, so that others skilled in the art may manufacture and use the same.

In the drawings, a represents the receptacle a rectangular boX or case-the top, sides, and' rear end of which are-closed, while the front end' is open, as shown in the drawings. In this case c are a series ofperforated shelves, b,

-which are preferably removable, sliding on the racks c. The bottom of the case a is also a sliding door, a..

Below the case is the heater or box d, open at the top and resting on a suitable support or legs, c. Inside of the box or case d are vone or more gasburners, f, the pur pose of which is to maintain the desired de-f.,

I prefer to form the receptacle a and heater d of sheet-iron; but, instead of the perforated metal shelves described, they maybe formed of asbestus, and in place of the perforations, or in addition thereto, (the purpose ofthe perforations being to allow the heated air from the heater d to pass into and to circulate in the receptacle a,) ues t, as shown in Fig. 3,.

may be formed at the sides and end of thereceptacle by the inner walls, i, the lines eX- tending from the bottom of the receptacle and opening into the interior of the receptacle above the upper shelf, a2, or at each of the shelves c3, or other suitable means may be employed for distributing the heat.

The operation is as follows: rlhe heater d being placedat the side of the workman, the gas being turned on and ignited, and the receptacle being placed on and over the heater, the work man as he finishes each article, instead of delivering it to a carrier, places it on thelowest shelf of the receptacle @,Yand so on until the shelf is lled. The sliding door a. is then raised until the `opening below the second shelf is closed, and the second and other shelves are then filled in a like manner, the door a being raised las each shelf is filled. When all the shelves are occupied by the articles of glassware, the door a is closed and fastened, and the receptacle-is removed from the heater d, carried to the leers or annealingoven placed therein, and allowed to remain until the glass issufficiently annealed. Another receptacle is then placed on the heater. Either natural or other gas may be employed in the heater d, or where neither of these heating agents can be obtained other means may be employed, such as a small furnace placed within the heater. The degree of heat necessary to be maintained in the receptacle d will vary according to the kind of glass* Ware being manufactured, I have found, however, QOQFahre'nheit to be suficientjin ordinary., cases.

The advantages of my improvement will be apparent to those skilled in the art, as the glass articles after being iinishedbeing maintained at the required degree of temperature, may be both being portable,may be moved to any de-4 sired position7 so as not to interfere With the Workman.. Y

In certain cases they gas-burners may be arl Y ranged within the receptacle aand detach ably connected With the gas-supply pipes, in which f case the separate heater would be dispensed with. i'

Insteadfof the shelves and doors described, the receptacle a may be formed in horizontal sections, having a perforated bottom and open 4top,as-shovvnin Fig. 4. These sections being placed one upon the other over the heater, and When a suitable number have been so placed together,bei`ng filled with glassware, the open In the manufacture of glass, a portable annealing box `or receptacle, in combinationwith a heater so arranged that the box may be maintained at the desired temperature prior to its being placed in the leers or annealingoven, substantially as and for the purposes specified:

2. In the manufacture of glass, a portable annealingreceptacle consisting of a case or box having a perforated bottom and shelves, in combination With a heater, substantially as and for the purposes specified.

3. In the manufacture of glass, a portable annealing box or receptacle having dues or passages, in combination With a heater so arranged that the receptacle may be maintained at the desired temperature by the'heat passing rf r/om lthe heater through the iiues or passages, substantially as and for the purpose specified.

4. A portable annealing-receptacle consisting of a box orvcase having shelves and a door or doors fo'r closing the openings in front of the compartments formed by-the shelves, in combination with a heater, substantially as and for the purpose specied. v

5.` A portable annealing-receptacle consisting of a box or case, in combination with a portable heater separable from the annealing box, substantially as and forthe purp'osespeci;A fied.

A 6. A portable annealing-receptacle, in combination With a fire-box and a gas-supply tube or tubes, substantially as and for the specified.

In testimony whereof vI have hereunto set my hand this 16th day of May, A. D. 1884. JAMES "DALZELL Witnesses: f W. B. CoRWIN,
