Specification of Letters Patent. Patented-Oct. 3, 1911.

Application filed January 5, 1911. Serial NoJGOOJJOREISSUED gage with the members 7 and '8 for the purpose o f uiding the cylinder 11 in its movements. Ihe member 7 carries a stop member 14 which may be adjusted upon the member 7 so as to limit the upward .movement of-the cylinder 11. 'If desired, an additional'stpp member may .beplaced upon--- the member 8. A packing ring is cu'rried by the piston 10which prevents tfljhe 65 leakage of fluid between the contactinggfsui faces of piston 10 and cylinder 11. At its upper end the cylinder 11 carries a platform 15. The upper surface of this platform is provided with an undercut groove 70 16, more clearly shown in Fig. 3. Two u-p rights 17 and 18 are provided with base por-- Be'it known that I, JOHN T. S'1oivnY,' a

Cleveland, in the county of Cu'yahoga and and useful Improvement in Molding-Ma-- chines, of which the following is a full, clear, and exact description.

2 This invention relates to machines for the making of molds and cores and provides a. machine in which the material from which to a jarring motion to compact it, and sub sequently the patterns are withdrawn from the mold'or the core from the core box.

Generally speaking, the invention comprises the elements and combinations thereof set forth in the accompanying claims.

Reference should be had to the accompanying drawings, in which- Figure 1' is a-front elevation of the machine in positionto jar the mold; Fig. 2 is a front elevation of the machine in 0- sition just before the pattern or core ox is withdrawn; Fig. 3 is a side elevation showing the mold or core box in elevated position before being rolled over. i

As indicated in the opening paragraph of the specification, this machine is applicable equally to the .making of molds from sand I or other material, or to making cores.

j A platform 1 is supported at its ends upon upright members 2 and 3, which may assume any desired shape. These side members are provided with central cross members such as shown at 4 iii-Fig. 3. A bracket5 which assumes'the general form shown in Figs. 1 and 2 is secured at its opposite ends upon the upright end ' eces 2 and 3 and depends between the same, being of such height as to justclear thefloor or platform upon which the machine may rest. Upon the lower portion of the bracket 5 are depend ing bosses 6 which may be threaded or other: wise prepared to receive uprights 7 and 8. 7

Upon the portion of the bracket 5, indicated at 9, an upri ht cylindrical member 10 is bolted or ot erwise secured. This cylindrical member may be hollow or solid; as desired, but in the drawings I have indicated it as hollow. For convenience I tions 19 which are forntfed with slanting sides in a manner to complement the groove 16 and are adapted to slide in this groove.

Openings 20 are provided in the table 15 through which bolts or other members maybe inserted to engage with the uprights 17 and 18, for the purpose of holding the up-;

rights in any adjusted position inthe groove 16. The uprights 17 and 18 extend through slots formed in the table, the positioning and extent f the slots are indicated at 17 and 18 in Fig. 2.

At their upper ends, the members 17 and 5 18 are provided with suitable trunnions upon which are pivotally mounted the members 21 and 22, which as will be clear from Fig. 3, are rectangular plates. These plates are provided with grooves, such, as shown at 23 and 24, and the grooves are adapted torcceive extending ribs 25 which maybe formed directly upon a flask or core box or the ribs may be provided by a band which surrounds the box and is suitably secured 5 in the plates 21 and 22. By the structure just described, it is possible to use flasks or core boxes of varying height and to seed just them that when the machine is in jarring position, the flask will be elevated from the table. A stop 'pin 28 extends through one of the uprights 17 and" engages with a depression formed in the member 22.

This

shall call the member 10 a piston. Sur rounding the upright piston 10 is a cylin der 11 which at its lower end isproyided with extendi sees-12 saa 13, which bosses'7'.are'p1% 1 with openings to em sto pin may be of any desired construction an is adapted to hold the flask or core be)? .against swinging-when in adjusted position. no A second .de ression 29 its-indicated in Fig. 1, with whic the ,pin will cooperate when the flask or core box is in a position the reverse to that shown in Fig. '1, viz: that shown in Fig. 2.

An air port 36' is located in the table 15,

5 or "the upper part of the cylinder 11,

through which ort air or'other compressed fluid is admitte to the interior of the cylinder 11 and the piston 10. Asa suitable means for introducing the fluid, I have shown a flexible pipe 31 which may be controlled by a valve 32. In ,the cylinder 11,

below the port 30, another port 33' is located which .is connected with a suitable outlet pipe 34, which pipe is likewise. controlled- 5 by a valve 35.

the port 33 rises beyond the top of the memeer 10, the air will exhaust through the port 33 and the pipe '34-, allowing the 'cylinder 11, and theparts carried thereby td drop or return to their. initial position. As

I soon as this dropping takes place, the port 33 will again be covered and the pressure within the members .10 and 11 will again raise the cylinder 11 and the parts carried thereby. This operation will be rapidly repeated and thereby impart to the mechanism carried by the cylinder 11 avibrating motions If the valve 35 be turned so as toclose the pipe 34, then as air is admitted through the pipe 31, the cylinder 11 and the .35 parts carried thereby will be raised until such time as the valve 32 -is closed or the boss 12 contacts with the stop 14. The ma-' chine as shown in Fig. l, is in proper position for jarring the mold or pattern box.

That is to say, the plates 21 and 22 rest upon the table 1, and as the cylinder 11 is raised and lowered,-these plates are raised from and contact with the table 1 and thereby jar the material within the mold or the pattern box. When it is desired to draw the pattern or the core, the mold or core box is raised, as suggested in'Fig. 3 and is turned over to the position shown in Fig. 2. It is i then lowered until the board 36 rests upon the table 1 or upon suitable devices adapted to receive the board 36. Then the clamps 37 are removed and the flask or core box, as the case may be, is elevated. This elevation is accomplished, as before stated, by admitting air through the pipe 31 and closing the valve 35. It frequently happens that the board 36 is not perfectly level, and therefore would not rest squarely upon the table 1. In order to provide for such a contin- 6 gency as this, I may use the devices such as indicated generally at 38, which are adaptto receive the board 36 and to automati *cally equalize, so as to support the opposite 'l ;.ends of the board. These devices eonsist of 651a base portion 39fwhich is provided'with' a rock to such position that the board 36 is tongue 40. A slide 41 is provided withfa groove complementarily with respect to'the tongue 40 so -that as the member- 41 slides movement." At substantially ,the central portion of the membei ul therbl-iii pivoted a support 42, so that the support may: rock about its pivot. When the mold or core 100::

, upo'nthe member 40, it will-be guided in its .is' lowered and the board 36- rest sfupon the members 42,they being freetomove, will supported at both its ends. For the purpose of holding the rocker members 42 in their final position, I have. provided a slot 43 in the rocker members 42, through which ex-' tends a screw bolt 44, which. screw bolt engages with a suitable dpening in the slide 41.

its soon as the "rockers 42 haveassumed their final position, the mold or core may be pulled out from beneath the devices carried by the plates 22 and 21. In this operation, the parts 41 slide upon the parts-'40 and thus make it easy to remove a heavy mold or core with a minimum chance of damage to the article which is being handled. As soon as the mold or core is removed from beneath ;the box, it may'then be removed from the ",rockers ..42, and these rockers may be returned to proper position to receiveranother mold or core.
