MOLD.

Specification of Letters Patent.

Patented Apr. 5 1910.

Application filed June 12, 1909. Serial No. 501,730.

To all whom it may concern:

Be it known that I, PETER HALL ALLISON, a subject of the King of Great Britain, and a resident of Torrington, in the county of Litchfield and State of Connecticut, have invented a new and Im roved Mold, of which the following is a full, clear, and exact description. j

' The invention relates to molds used for casting ingots, such as brass bars, to be subse uently rolled into sheet or other form.

he object of the invention is to provide a new and improved mold capable of being opened. and closed without ta ing up much floor space, and arranged ,to prevent the formation of fins and to allow convenient and quick removal of the casting irrespective of any change in the members of the mold owing to expansion and contraction.

For the purpose mentioned, the mold is formed of two mold members, hi ed together at one side, to allow of swinging the mold open in a lateral direction.

Figure 1 is a side elevation of the mold; Fig. 2 is a transverse section of the same; and Fig. 3 is a sectional plan view of the same.

The rear and front :mold members A and B are made approximately L-shape in cross section, and the rear member A is provided with a forwardly projecting bottom A forming the bottom of he mold. On one side of the mold memb rs A and B are formed the hinge eyes C and D, engaged by vertically disposed alined pintles E, to permit of swinging the front mold member B toward and from the rear moldmember-A on closing or openin the mold. The center of the hinge, forme by the lugs G and D and the pintles E, is somewhat forward of the adjacent side of the rear mold member A, as plainly indicated in Fig. 3, so that the L-shaped mold member B can be readily swung into a closed position against the when casting the in ot in the mold. Each of the joints F,'F', is formed, by providmg a right angled'corner in one member, engaging a correspondingly-shaped rabbet on the other member, as plainly indicated in Fi s. 2 and'3.

K locating the axis or center of the bin e in t e manner described,,it will be readi y seen, by reference to Fig. 3, that the mold member B can readily swing into closed or open osition without danger of binding at the joints F, F and F, at the same time insuring proper seating of the joint members to prevent leakage and the formation of fins when pouring the molten metal into the mold. When doing this, the mold members are preferably locked m a closed position by suitable clamps G, as indicated in the drawings. After the casting is made the clamps G are removed and the member B is swung.

open in a lateral direction, so that the casting can be readily dropped out of the rear member A of the mold.

It will be noticed that by making the joints F, F, F in the manner described,

they are not affected by the expansion and contraction of the mold incident to the for mation and removal of the ingot, so that the mold can be used over and over again without danger of forming undesirable fins.

The under side of the rear mold member A projects a distance below; the under side of the front mold member B, so that when the mold is resting on a suitable foundation, the under side of the front member B is free of the support and can be readily swung into an open or a closed position.

It is understood that when the mold members A and B are closed and the molten metal is poured into the mold, all the strain is taken up by the machined and the interlocked joints, thus relieving the hinge of undue strain.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A mold comprising two mold members hingedly connected with each other at one side, the members being approximately L- shape in cross section, one of the members having an integral bottom, the said members having joints at the bottom and sides, the said joints each comprising a right-angled corner on one member engaging a corremember.

right angled corner on one member engag ing a correspondingly shaped rabbet on the other member, the vertical axis of the hinge being forward of the adjacent joint of the members.

3. A mold, comprising a rear member, a front member, and a hinge connecting the said members with each other at one side and a distance forward of the rear member,

, the said members being L-shape in crosssection and the rear member having an integral bottom and a cutout portion at the top.

4. A mold, comprising a rear member, a

front member, and a hinge connecting the said members with each other at one side i and a distance forward of the rear member, the said members being L-shape in cross section and the rear member having an integral bottom and a. cut out portion at the top, the joints of the said members being machined and interlocking.

5. A mold, comprising a rear member, a

front member, and a hinge connecting the said members with each other at one side and a distance forward of the rear member, the said members being L-shape in cross section and the rear member havmg an integral bottom and a cut out portion at the to the joints of the said members bein and interlocking, and means for ioldin the free ends of the said .members lock in closed position. 1

6. A mold comprising a rear member, a front member and hinges connecting the said members with each other at one side and at a point forward of the rearmember, the said members being approximately L-shape in cross section and the rear member having an integral forwardly projecting bottom forming the bottom of the mold, and a cut out portion at the top, the lower face of said rear member projecting below the lower face of mac ined the front member, and clamps for holding 4 the mold members in closed osition'.

In testimony whereof ave signed my name to this specification in the presence of two subscribing witnesses.
