Specification of Letters Patent.

Patented Sept. 5, 1911.

Application filed May 6, 1911. Serial No. 625,605.

To all whom it may concern:

Be it known that I, LON KIMBALL, a citizen of the United States, residing at Fort Smith, in the county of Sebastian and State of Arkansas, have invented certain new and useful Improvements in Mold- Jackets, of which the following is a speci-' and end plates, and a clamping frame adapted to press and hold the sides of the jacket together; and an important advan tage of the construction is that the top plate and sides are loosely connected and will accommodate themselves to slight variations in molds, incident to variations in size of flasks.

A further novelty of construction is that the various parts are separable, so that clogging is prevented, and bursting of the mold will not destroy the efiectiveness of the jacket for further use.

Various other advantages will be apparent to those skilled in the art, from the structure as disclosed in the following specification and the accompanying drawings.

In the drawings,Figure 1 is a perspective view of the jacket, in closed posit-ion. Fig. 2 is a perspective view illustrating the 7 application of the jacket to a mold, as the jacket is about to be put in position and be fore it is tightened on the mold. Fig. 3 is a plan view of the top plate. Fig. 4; is a perspective view of one of the end plates. Fig. 5 is a detail in section of the clamping frame.

Referring specifically to the drawings, 6 indicates a top plate which is made with openings 7 for gating the casting in the mold and for allowing the escape of gases from the mold, as well as to lighten the structure. This plate is provided at its edges with extendlng eyes or loops 8, which serve the purpose of connecting the sides and ends to the top plate as hereinafter described.

The side plates are indicated at 9 and end plates at 10. These plates are preferably cast with openings 11 therein to lighten the jacket and allow the escape of gases. Each side and end plate is provided at its upper edge with hooks 12 which are adapted to fit into or through the eyes 8, the points of the hooks being directed outwardly. The eyes are somewhat larger than the bodies of the hooks, so that the latter will have a certain amount of play in the eyes, in order that the walls of the jacket may accommodate themselves to slight variations in the size of the molds. When the parts are assembled the side and end plates are supported by or hang from the eyes at the edge of the top plate, in a loose manner, and the shape of the hooks 12 is preferably such that the plates will tend to swing or open outwardly to a certain extent, in consequence of the point of suspension being slightly offset from the plane of the plates, when the hooks are resting on the eyes. Each of the side and end plates is made or provided with external inclined or wedge shaped ribs 13, extending vertically, and conveniently positioned directly under or forming a continuation of the hooks referred to, although this particular arrangement is not essential.

A clamp or binding frame 14 extends around the wall of the jacket, and this is of such proper size that its inner edge rests against the ribs 13, and when pushed down the wedging action of the ribs presses the plates together, and against the sides of the mold on which the jacket is placed. When the binder frame is lifted it contacts with the underside of the eyes 8, and thereby supports the jacket when it is being placed on or removed from the mold, as shown in Fig. 2, in which position, as above stated, the plates will tend to swing apart sllghtly so that the jacket may be readily placed upon or drawn from the mold. The blnder frame 1 1 is thus confined between the extended eyes on the top plate and the lower part of the inclined ribs, and hence after the parts are once assembled they are all held together without possibility of accldental separation.

In order that the binder frame may be put in place, it is necessary that some of the ribs .13 be detachable, and I have so illustrated the same in Fig. 4:, on one of the end plates,

the ribs being fastened to the plate by any suitable means, such as screws 15. These screws may be taken out and the ribs taken off to permit the binder frame to be slipped on or off as necessary. After the binder frame is taken off, the side plates can be detached from the top plate by swinging the former outwardly to drop the hooks from the eyes, but while the binder frame is in position it is impossible to detach the parts.

In the use of the device, the flask having been removed from the mold, the jacket is lifted by means of the binder frame, permitting the walls to open or swing outwardly and the jacket is then lowered on or around the mold. The frame 14: is then pressed down, and by contact with the wedge correspond to the mold or flask.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is 1. A mold jacket comprising a top plate having eyes at the edge thereof, adjustable sides having hooked projections engaging in said eyes, and a frame extending around the sides and adjustable to clamp the sides against the mold.

2. A mold jacket comprising a top plate having projectin eyes at the edge thereof,

adjustable sides having hooks at the upper edge thereof loosely-engaged in said eyes, and a vertically adjustable clamping frame extending. around the sides and confined by said eyes when the frame is lifted.

3. A mold jacket comprising a top plate having eyes at the edge thereof, sides having hooks at the top edges thereof, extending through said eyes the points of the hooks projecting outwardly and adapted to rest on said eyes, so that the sides will swing open when free, and a clamping band extending around the sides and adapted to close the same.

4:. A mold jacket comprising a top plate having openings at the edge thereof, side plates having hooks at the top edge loosely engaged in said openings, whereby the side plates are flexibly hung from the top plate, said side plates having inclined ribs on the outer side thereof, and a binding frame extending around the side plate and adjustable up and down thereon and confined between said ribs and top plate.

In testimony whereof, I afiix my signature in presence of tWo witnesses.

LON KIMBALL.
