` Beit known that I,1ALv1vNi BECKER,

c'itizen of the United States,- re'siding at Belleville,-in the county of St. Clair, 'State ,oll'llin'ois have invented certain newand.

useful Improvements in Molders Flasks; and Ido'he'reby declare theI following tobe a *fu1l,` c1ear, and exact description of the invention, such as 'will enable others-skilled 'l0- ihr-the' are to' which it appertains to` make IThis invention relates. to improvementsl in 'the art of vlmolding and has for itsv object the provision of an improved form ofl cope bar 'or-holding the sand anchors. 1"." u Anotheri object is thel provision of a means for adjustably securing the sand anchorsat various positions inthe bar. j A. further object is the provision of'an improved form of sand'anchor.- i

With these and other objects in view as .will more fully hereinafter appear, "the presentinvention' consists in certain 'nove1' details of constructlon and arran ement ot.

parts, hereinafter Afully described, illustrated 1nl the accompanying drawings and moref particularly pointed out in the appended claims, :it being4 understood that Various .changes in the form, 4proportion,-.size and' minor details of the 4device may be made ficing any of the4 advantages of the inveni'ask`in 'side elevationand the cope in-longitudinal section and provided with'.'1ny improved cope bar and sandanchors," the bar yand anchors being shown 1n side elevaition..

elevation of lthe i anchors.

modified yform of sanu f In .the vdrawings the cope of a mold is shown at A .and-2.

" As shown i and lthe' drag at B in Figs. 1

lxlthe. drawings, the opposite ends of the cope are 'designated by the e numerals 5 and `6 and the sides by the numeral-7. The; construction about to be de sand has been packed therein about the pattern, must be turned-.and the pattern withdrawn and then turned. again and placed in position on the drag or lower men'iber. The

bar which forms "part of the vsubject-matter of the present invention in the present instance is designatedby the numeral'S and is of a lengthj 'correspondngto the distance- 'between thevopposed inner faces of the end Walls 5 andl 6. In the present instance thisbar is shown provided at its opposite ends with a pair .of spaced .tongues9 which are to besecured in theendl Walls of the` cope when the latter is-of wood, butv this construction will 'notqbeemployed when` the cope is metal; in the lattericajse screws or 'bolts will" be employed inl lieu of the tongues .9... 'I i By. referring now to Fig-s. 1 tol 3 inclusive A it will be seen that-the bar is provided with three or more.verticalopenings designated hy the numeral '10; ,These openings forni guides for the reception of the Shanks of the` sand anchors. The sand anchors' are 'all identical in structure'soa description of one.

will be sufficient. 'By referring now to Figs. l .to 3 inclusive it'will he seen that each anchor consists of a shank portion 11 which is preferably formed of a single piece. of sheet metal or the like and, of a size'` to slidingly fit in the guide .opening 10. `lVhat` will subsequently be termed 4 the lower end ofv the shank l1 is .pro-

"vided'on its opposite sides with enlarged bosses'or heads l2 and secured in the lower .ends ofthe heads 1Q are the sand supportsv Each. of these memberspreferably.

13. formed of a cylindrical shank' which ise'nrl bedded and firmly'secured inv the' vboss and, terminates' at its opposite end in 2in-enlarged.

flat head. 14.-. As shown inthe drawings these members are disposed at., an acute angle to the shank 11.0f the' vancl'ioriit is to be understood, however, that I'alnnotto be..

limitedto this speciiic disposition sinceit 55 diameter of the opening presented by the dewill be understood lthat the supports may occupy any anglejor extend vertical with respect tothe shank 11.

By referring now vto Figs. 1 to 3 inclusive it Will be seien that thel bar is formed with three or more laterally Aextending I threaded openings 15 whichf'are disposed in alinement with, the central line'of the bar zoy eral by the numeral 18 and is provided with provided on one of its -faces andadjacentl and lead into the guideopenings 10. The openings 15 receive the threaded shank of a set screw 16,' the outer` end ofwhich is prol vided with a milled head 17, by means of "which the screw is" turned so as to lock the a plurality of spaced vertical guide openings 19 disposed similar tothe openings 10 in the first-named bar. The guidevopenings 19 are provided on one of their sides and adjacent their opposite-ends with a pair of vertically extending and semi-circular shaped depres-g' sions 20 and slidingly fitted in .the guide openings 19 is what will subsequently be termed a clamping block or member 21. This member is preferably formed of a single block of metal, the length-of which corresponds to the width of the bar 18 and is its opposite sides with a pairof vertically extending yand semi-circular shaped 'depres-A sions 22, which are coincident'with the depressions 20 in the block. It might here be stated, that the thickness of the clamping blocks 'is considerably less than the width of the guide openings 19 sol that when that face of the clamping block opposite the face in which the semi-circular depressions are lformed bears on thatside 'of the opening 1Q remote from the depressions 20,' the open-4 ing presented by the depressions will'be considerably greater than when that side of the clam ing block upon which the depressions are orined bears on that side of the bar in which the depressions-20 are formed.

.The modified form of anchor shown in the j drawings consists 'of an elongated shank portion 23 one end of which terminates in a hat head 24.. The diameter of the shank portion 23'is considerably Igreater thanthe pressions 20 and 22 when the clamping block bears on that side'of the opening in which the depressions 2x0 are formed.

- By referringnow to Fig. 6 of the draw.

' it Will ,beseen that the bar 18 is prodd with a plurality of laterally extending threaded openings 25, which extend through that side of the'block opposite to the side in jvhc'h the depressions 20are formed and threaded into these openings are set screws 26, `the outer sides of which are provided with heads 27. Thus 'it can be seen when the Shanks 23 ofthe anchors are placed Within the openings they may be locked therein b v turing the set screws 26, it being understood that the threaded terminals ofthe latterV will bear on that face of the clamping blocks opposite to the face in which the depressions 22 are formed. -If desired the depressions 20 and -22 at the opposite 'ends of the openings and blocks maybe formed at an angle and extend i-n ropposite .directions which will, of course, permit the anchors to be disposed at an angle with respect to the block.

In the use of the device the vshanks of the anchors are inserted into the guide openings with their lower ends disposed in the sand within the cope and as shown when adjusted to the proper height according to the pattern Within the drag a slight tap with a hammer or the like on top of the shank is all that is necessary to adjust the anchors in their rel-A ative positionsv around the pattern in the drag. VVhenthe parts are in thisposit-ion byl turning the set screws they' may be se-.

curely locked.

From the foregoing it will be seen that the anchors are so arranged within the bar and cope as to render the. same capable of use with any shape of configuration' of pattern within the limits of the capacity of the device. It will be further observed that with ment of the bars is needechsince it can be seen that the irmretention of the molded sand in the flask will be secured by the provision of the adjustable anchors after the n pattern has been. withdrawn. Having thus described my invention what is claimed as new, is 2*- 1. In a inolders flask a supporting bar-v havlng'an opening extendingl therethrough.

and a threaded openingcommunicating with lthe first-mentioned opening, a clamping screnT in the said threaded openingand an through the same, in combination with a' head having a. shank extending through said openinr and adjustable therein, said' head being Iurther provided with a plurality of `anchor having a. shank extending through sand anchors, and means to secure the said shank adjustablv in-the said opening of the said supporting bar.

. In testimony whereof, I aHix my signa-.

tu re, in presence of tivo witnesses.
