JOHN MCLAUGHLIN, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR T0 HIMSELF ANI) JACOB APPLE, OF SAME PLAGE.
Letters Patent No. 106,850, dated August 30, 1870.
IMPROVEMENT IN -MOIIIIIDING--Il-"LnASKS.
` The Schedule referred to in these Letters Patent and making part of the sama I, JOHN MGLAUGHLIN, of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented an Improvement in Molding-Flasks, of which the following is a specification.v
Nut-ure and Object of the Invention.
My inventionconsists in the combination, substantially as -described hereafter, of certain detachable cross-bars and metal sockets, with the cope of a molding-flask, so as to permit the ready removal of burnt cross-bars, and the ready attachment of new ones, and so as to prevent the cope from being ignited hy burning cross-bars.
Description of the Accompanying Drawing.
Figure 1 is a perspective view of my improved molding-ask.
Figure 2, a vertical section of the same.
Figure 3, a verticahsection of part of the upperA portion ofthe dask or cope, drawn to an enlarged scale; and
Figure 4, a perspective view of one of the sockets attached to the cope.
General Description.
A represents the lower portion of a molding-box or flask, and
B the upper portion or cope, both consisting of side and end strips of wood, -dovetailedor otherwise se- 'sometimes communicating with the side strips of the flask, and injuring or destroying the same.
In place of cross-bars nailed to the cope, I use detachable bars, D, the ends of which are adapted to lnetal sockets, E, attached to the inside of the opposite side strips ofthe cope B in the following manner:
At the real-of each4 socket are cast upper and lower pins, e and e', which I prefer to make ot' the tapering form represented, and which it snugly in corresponding orifices in the cope. After these sockets have been arranged in their proper position, the cross-bars are fitted to them, as shown in figs. 1 and 3, and these cross-bars serve to retain the sockets in their places. The cross-bars'themselves may be so retained by plus, j; of hard wood or metal,- as to prevent their vertical displacement.
I prefer to make the sockets, at the point where the the ends of the bars bearagainst them, slightlyinclined,`as shown in tlg. 3, so that the bars maybe driven tight into their places.
My invention not only permits the ready removal of burnt cross-bars, and the equally ready introduction of new ones, but the sockets serve as barriers to prevent ignited cross-bars from setting fire to the cope. The expense of the numerous nails heretofore required in securing the cross-barsis obviated.
Claim.
The combination, substantially as described,'of detachable cross-bar or bars D, and sockets E, with the cope of a molding-flask.
In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.
Witnesses: l, JOHN MOLAUGHLIN F. B. RICHARDS," WM. A. STEEL.
