To all whom it may concern:

Be it knoivn that I. JOHN T. SToXEY, a citizen of the United States'residing at Cleveland. in the county of Cuyahoga and State of Ohio, have invented nevv and use-' ful. Improvements in Holdingffachines. of which the following is a specification.

This invention relates to machines for the making of molds and cores and provides a machine in yvhich the material from which the mold or core is made may be subjected 'to a jarring motion to compact it. and subthe specification,

sequently the patterns are ivithdravvn 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 vvhich Figure 1 is a front elevation of the machine in position to jar the mold; Fig. Q is a ,front elevation vvith portions in section of the machine in position just before the pattern or core boxl is Withdrawn; Fig. 3 is a side elevation vvith portions in section shovving the mold or core boxin elevated position before being rolled over.

yAls indicated in the opening paragraph of y this machine is applicable lequally to the makingof molds from sand or other material. or to making cores.

A platform 1 is supported at its ends upon upright members 2 and which mayT as suine any desired shape. These side members areprovided vvith central cross mem# bers such as shoivn at l in Fig. A bracket which assumes the general form shovvn in Figs. 1 and 2 is secured at its opposite ends upon the upright end pieces Q and 3 and depends between the same. being of such height as to just clear the floor or platform upon which the machine' may rest. Upon 'the lowerportion of tllj bracket 5 are dependingv bosses 6 vvhich may be threaded or otherwise prepared to receive uprights 7 and S. Upon the portion of the bracket 5. indicated at 9, an upright cylindrical meimber 10 is bolted or otherwise secured. This cylindrical member maywbe holloiv or solid. as desired. but in the drawings I have indicated it as hollow. For convenience I shall call the member 10 a piston. Surrounding the upright piston 10 is a cylinder' 11 which at the limits of the machine.

a more universal machine.

its lovver end is provided vvith extending bosses 12 and 1B, which b osses are provided with openings to engage with the members 7 and 8 for the purpose of guiding the cylinder 11 in its movements. T he member 7 carries a stop member 1l vvhich may be adjusted upon the so as to limit the member 'i v upward movement of the cylinder 11. If desired, an additional stop member may be placed upon the member S. A packing ring 10a is carried by the piston 10 vvhich pievents the leakage of Huid betvveen the contacting surfaces of piston 10 and cylinder l1. At'its upper-end the cylinder-11 carries a platform 15. The upper surface of this platform is provided with an undercut groove 16. more clearly shown in Fig. 3.

Two upriglits 1T and 1S are provided with base portions 19 Which are formed With slanting sides in a manner to complementthe' groove 16 and are adapted to slide in this groove. Openings 20 are provide in the table 15 through ivhich bolts or other members may uprights 1T and 1S. for the purpose of holding the uprights in any adjusted position in the groove 16. The uprights 17 and 18 extend through slots formed in the table7 the positioning and extent of the slots is indicated at 1Tn and 1Sa in Fig. '2. The bolts are but indicative of any suitable means to hold the uprights in position.

The uprights 1T and 18 may be moved toward and from the center of the machine. and. by proper adjustment. may be made to accommodate aflask of any Width ivithin T his adjustable feature provides vvl'iich. is particularly desirable in molding machine.

At their upper ends. the members 1T and 18 are provided vvith suitable trunnions upon which are pivotally mounted the members 21 and 22. which. as ivill be clear from Fig. 23, are rectangular plates. These plates are provided vvith grooves. such shown at '23 and '24. and the grooves are adapted tolreceive extending ribs 25 which may be formed directly upon a flash or core box or the ribs may liese a small be otherwise provided. projecting members are held from slipping oi sliding in the grooves by means o bolts 26 which extend through suitable openings, such as illustrated at 2T in the be inserted to engage vvith the' plates "21 and 22. By the structure just described, it is possible to use iasks or core boxes ot vary-ing height and to so adjust them that when the machine is in jarrmg position, the tlash Will be elevated from the table. stop pin 2S extends through one of the uprights 17 and engages with a depression formed in the member rThis stop pin may be of' any desired construction and is adapted to hold the flash or core box against swinging when in'adjusted position. A second depression 29 is indicated in Fig. 1, \vith which the pin will Coperate when the asli or core boX is in a position the reverse to that shown in Fig. 1, vin-that 'shown in Fig. 2.

An air port 30 is locatedin the table 15, or the upper part of the cylinder 11, through which port air or other compressed liuid is admitted. to the interior'of the cylinder 11 and the piston-10., ,es asuitable means for introducing` the fluid, I have shown a tieni# ble pipe 3l .which may be controlled by a valve In the cylinder 11, below the port 30, another port 33 is located4 which. is connected with a suitable outlet pipe 31".Which pipe is likewise controlled b v a valve 35. In operation compressed air or other Afluid will be admitted through the port which will cause the cylinder 11 andthe parts carried thereby to be elevated. -Hoivever,

when the port rises beyond the top of the member 10, the air. Will exhaust through the port 33 and pipe 3l, allowing the cylin,

der 11, and the parts carried thereby to drop or return lo their initial position. As soon as this dropping'takes place, the port 33 will again beco-vered and the pressure with# in the members 10 and 11 will again raise the'clyimlerll and the parts carried thereby. This operation Iwill be rapidlj7 repeated and thereby impart to the n'iechanisn'i oarried by the cylinder 11 a .fibrating motion. 1f the valve is turned so as to close the pipe 3i, then as air is admitted throughthe pipe 231, the cylinder 11 and the parts carried therebyv ivillbe raised until suchtime as the valve 32de closed or the boss l2 contacts with the stop 14. The machine as "shown yin Fig. 1, is in proper position for jarring the mold or pattern box. That is to say, the plates Qland 22 rest upon the table 1,- and as the cylinder 11 is raised'and 10W- ered, these plates are raised from and Icon tact with the table l 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, als suggested in Fig. 3 and is turned over to the position shown in Fig. 2. 'It is then lowered until the board 36 rests upon the table fl. or 'upon suitable device adapted to re ceive the board 36. Then the clamps 37 are removed and the flask or core box, as the fase may be, is elevated. This elevation is accomplished, as before stated, by admit-t ting air through the pipe 3]. and closing the' valve 35.' j

It-frequently. happens that the board 36k is not perfectly level, and thereore-ivouldnot rest squarely upon -the tabie'l. Inorder to provide for such contingenpy as this, lv may use the devices'sue'h as ,int'iea nerally at 38, Which'are adapted to rece ,v board 3G and to' a'.itomaticalljT equalize, as to support the opposite lends ot' the board. These devices consist of a base portion 39 which is provided with a ytongue 40. A slide 41 is provided with a groove complementary with respect to the tongue 40 so that vas the member 4l slides upon, the `member '40, it will be guided in its move-ments. .i At

substantially the central portion of the*- member 41 thereis pivoted a 'support 42 so that'thesuppor't may rock about its pivot. Then the moldor vcore box is lovvere'ad'v and' the board 36 rests hpon thevmembers 4 2,

they being free to move, ivillrock tosuehposition that the board 3G isv supported at both its ends.

For the purposeof h'olding'the rocker members@ in their nal position, 1" have provided a slot 43' in the lrocker members 49 through which extends a screw bolt 44,

which screw bolt 'engages with a"suitable" opening in the slide 41. As soon as the rockers 42 have assumed their final position, the' mold or core may be pulled ont from beneath the devices carriedby the plates and 121. In this'operati'on, theparts'll slide upon the parts 'O and thus malte it easyto remove a heavy mold or core with a 'minimum chance ofdamage to the article "which is being handled. As soonas the mold-or core is removed from beneath the box, it may then be removed from the rock` ers 42, and these rockers maybe returned to proper position to receive another mold or core. j
