IMPROVEMENT IN MANUFACTURING GLASS-WARE 'WITH HANDLS.

TO ALL WHOM IT MAY GONCERN:

Be it known that we, J. S. Arrnnuunr and T. B. Arrnnnunr, of Pittsburg, in the county'ot Allegheny, and State of Pennsylvania, have invented a new and useful Improvement in the Manufacture of Glass-Ware with Handles; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a. perspective view of 'moulds which arc adapted for the manufacture of small hand-lampswith handles. i

vFigure 2 is a dia-metrical section through alamp and its handle within two of the half sections ot" its mould.

Figure 3 is a side view of the product of the moulds shown in fig. 1.

Similar letters of reference indicate corresponding parts in the several gurcs.

This invention relates to au improvement in the manufacture of blown-glass lamps and other articles of blown glass requiring handles upon t hem.

' Under the old process of making such articles as we have above mentioned, the work of shaping and applying the handles is a separate operation fromthat of blowing the bodies of the articles, and requires the experience of skillful workmen, who are guided by the eye alone in the performance of this part ofthe work.

The object .of our invention is to greatly facilitate the process of making lamps and other articles in glass requiring handles upon them, and at the same time to produce such articles in a more perfect manner than hitherto, by providing suitable moulds in which the body of th'e article which it is desired to make can be blown, and the handle produced and attached permanently to it at successive operations in the same mould, as Awill be hereinafter described.

To enable others skilled in the art to understand our invention, we willj describe its construction and operation.

Inthe accompanying drawings we have represented 'one form of moulds adapted for producing lamps with handles upon them, and from a description of these moulds, andthe process of making the lamps, it will be seen that other articles can be produced in the same manner by simply changing the shape of the moulds, without departing from the principle of our invention.

A A represent two half sections ofthe mould, which are adapted for giving shape to the lower portions of the body and handle ofthe lamp, G, and B B are-two half sections which are adapted for giving shape to the upper portionsfot` the body of the lamp and its handle.

The sections or halves A A are suitably hinged together, `and provided withlhandles, C A@by which they can be opened and closed; and on top of these sections are elevations, which are adapted to receive corresponding recesses in the bottoms of the upper sections B B', as shown in gs. 1 and 2, so that when the two sections forming thclmould complete are put together they will be properly matched, and will be held in place.

The upper halves, forming the upper section ofthe mould, are suitably hinged together, and provided with handles, C C, likethe lower halves of the mould, and through the centre of this upper` section a. hole, c, is made, which produces the neck ,or rim of the lamp, a s"ishowu in iig. 2.

In tig's. 1 and 2, a a', I b', and c e represent the matrix in which the body of the lamp is produced, and g g g, y g' g represent the matrix in which the handle. of the lump is produced. It will be seen that the matrix for the 'handle is in communication with the matrix for the body.

The operation of producing the lamps with handles upon them is as follows: We first close the two halves forming the lower section of the'mould, and pour hot glass into the matrix g g', which glasswill flow to the bottom of this matrix. The workman, during this last operation, prepares his ball of glass, which is blown round, or nearly-thc shape ofthe body ofthe lamp. This ball is then -introduced into the lower matrix a, and the upper section of the mbuld adjusted in place vover it, after which the workman blows and expands the glass in the mould so that it will conform thereto, and at the same time attach itself rinly to the exposed heated glass in the matrix g g, thereby forming the body of the lamp, and attaching its handle, J, to it at one operation. The mould is then opened 11n-d the finished lamp taken out', for a. ijepeti'tion ofthe process.

Having described our invention, whatwe claim as new7 and desire to secure by Lett-ers Patent, iss--A A glass lamp, or other article in glass,l1eving :L moulded or cast handle and e. blown body, produced substantially as described.
