Patented Oct. 7, 1930 UNITED STATES PATENT OFFICE ARTHUR T. BATE MAN AND FRANK E. STOREY, OF DETROIT, MICHIGAN, ASSIGNOBS TO IBOHN ALUMINUM & BRASS CORPORATION, 013 DETROIT, MICHIGAN, A CORPORA- TION OF MICHIGAN I MOLD STAND Application filed-August 27, 1928 Serial No. 302,284.

The invention relates to stands for supporting molds and has for one of its objects the mounting of a mold so that it may tilt during the casting operation and thereby pro- 5 vide for the escape of air from the mold cavity and the filling of the mold cavity with the molten metal. Another object is to so mount the mold that it may be continuously tilted during the pouring operation. Further 10 objects of the invention reside in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.

In the drawings Figure 1 is a front elevation of a mold stand embodying our invention;

Figure 2 is an end elevation thereof.

For the purpose of providing for the escape of air from the mold cavity of a mold so that this mold cavity may be completely filled with molten metal, we have provided a construction of mold stand by means of which the mold may be tilted during the casting operation. As shown, 1 is the base of the members 2 at its ends, each of which has formed in its top the transversely extending V-shaped groove 3, the grooves of the two frame members being in alignment. 4 1s aannular passage 10 which encircles the mold cavity and is connected therewith by suitablerestricted passages 11. Furthermore, the mold has the vent passages 12 leading upwardly from the annular passage 10 to thetop of the mold. The arrangement of mold is such that air within the mold cavity may escape through the restricted passages 11,

the annular passage 10 and the vent pasmold stand having the triangular frame pivotal member or platform upon which is fixedly secured the base 5 of the mold 6.

foractuating said movable member to For the purpose of swinging the pivotal member 4 upon the base 1 to thereby tilt the .mold so that the air in the mold cavity will not be trapped and can completely escape, we have provided the lever 13 pivotally connected to the base 1 near its bottom so that this lever may be actuated by the operators foot. 14L is a rod pivotally connected at one endvrto thelever 13 and at the other end to the pivotal member 4 laterally beyond the gudgeons 7. To normally hold the pivotal member 4 in a predetermined position relative torthe base 1 and in the present instance in a horizontal position, we have provided the coil spring 15, one end of which is'connected to the pivotal member 4: on the side of the gudgeons 7 opposite to the pivotal connection of the rod-14 to the pivotal member 4:. -The other end of this coil spring is secured to the base 1 near its bottom. 17 and 18 are brackets secured to'the base 1 near its topand on opposite sides ofthe gudgeons 7 for re spectively limiting the swinging move- .ment of the pivotal member 1 under the influence ofothe coil spring 15 and the influence of the lever 13 and the rod 14;. I

l Vith this arrangementof molding stand, the operator may during the pouring of molten metal through the gate 9 into the mold cavity 8 gradually and continuously swing the pivotal member 4 to thereby tilt the mold by applying foot pressure upon the lever 13. As a result, air within the mold cavity may be completely displaced by the molten metal and escape through the restricted passages 11, the annular passage 10 and the vent passages 12.

What we claim as our invention is:

1. In a stand for supportinga mold, the

combination of a base, mold supporting means upon' said base, including a member movable to provide for tilting of the mold, and means provide for continuous and gradual tilting of the mold during the pouring operation.

2. In a stand for supporting a mold, the combination of a base, mold supporting means upon said base, including a member movable toprovide for tilting of the mold, a pivotal lever uponsaid base, and means connected to said lever and movable member for actuating the latter from the former.

3. In a stand for supporting a mold, the combination of a base, a mold supporting pivotal member upon said base, a pivotal lever upon said base, agd means between said pivotal member an lever for actuating the former from the latter.

n a stan fe urro i a m l he qenbiaati n f a a m d upp r i member pivotally mounted upon said base, means between said pivotal member and base for resiliently holding said pivotal member in a predetermined position relative to said base,a pivotal lever upon said base, and means between said ivotal member and lever for swin ng the ormer from the latter.

6. n a stand for supporting a mold, the combination of a base, a mold supporting member mounted for tilting movement on said base, ieldable means for normally maintaining sa d member in a predetermined position and resisting movement thereof,' and means for tiltin said member against the resistance of said %rst named means during the pouring operation.

" 0. Int. stand for supporting a mold, the combination of a. base, a mold supporting member mounted for tilting movement on said base means for normally maintainin said member in a predetermined osition an resisting movement thereof, an means for tiiting said member against combination oi a member mounted said base, resilient base, "a mold supporting for tilting movement on means for normally maintaining said member in a predetermined position and resisting movement thereof, and means for tiltin 4 said member against the resistance of sai first named means.

8. In a stand for supporting a mold, the combination of a base, a mold supporting member mounted for tilting movement on member against the resistance of sa d first named means during the pouring operation. 10. In a stand for supporting a mold, the

combination of a base, a mold supporting member pivoted intermediate its ends upon id base, a spring at one side of said PIVOt r resisting movement of said supporting the resistance of said first named means, including a foot I operated lever pivoted on said base.

7'. In a stand for supporting a mold, the

member, and means at the opposite side of said pivot including a lever pivoted to said base for moving said supporting member against the tension of said spring.

11. In a stand for supporting a mold, the combination of a base, a tiltable mold supporting member upon said base, and means providing for the gradual and continuous tiltinglof the mold during the pouring operation inquding an actuator for said mold supporting member. y

12... In a stand for supportin a mold, the combination of a base, a tiltalie mold sup- PQIQ member upon said base, means for norma y maintaining said member in a pre determined position and resisting movement thereon and manually operable means for tiltin said member against the resistance of said rst mentioned means.

In testimony whereof we aflix our s1gna-' tures,
