MOLDERS FLASK.

' Specification of Letters Patent. Patented Apr; 13, 1915.

Application filed December 26, 1914. Serial No. 879.080.

To all whom it may concern Be it known that I, FRANK HAETTEL, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Molders Flasks, of which the following is a specification. 4

- My invention relates to molders flasks and has particular reference to a peculiarly novel,-adjustable pin connectionbetween the cope and drag forming such flask.

The main object of my invention resides I in the provision of a structure of the type of guide "pin,

referred to which may be easily adapted for use with. hand flasks or machine flasks as the case may be.

Furtherm construction 'is particularly adapted. fof use upon work requiring a great amount of skill and wherein it is essential that there 'be no relative shift between the cope and drag itself after the patand drag when a portion-of the imprint ext-nds into the cope. I

My invention also contemplates a structure wherein the mile pinfproper may be emoved from eacl leted and used upon the succeeding flask. Thi -construction also is such that the guide pit/may be adjusted in any desired position mthrespect to the flask to maintain the two.

parts in a predetermined position when the pin is in use.

The preferred embodiment of my invention is shown in the accompanying drawings, in which similar characters of reference designate corresponding parts, and in whichf Figure 1 is a view in perspective of a flask showing my inventionapplied thereto, Fig. 2- is a view in perspective of the cope plate, Fig. 3 is aview in perspective of the drag plate, Fig. 4 is a view in perspective of the guide pin and its cooper-at ing parts, Fig. 5 is a slightly modified type Fig. 6 shows the guide pin structure shown in Fig. 4 in its assembled relation With the cope and drag plates, and Fig. 7 is a similar view showing a modified type of construction of Fig. 5 in assembled relation with the cope and drag plates.

In these "drawings, the flask is shown as formed of the usual ty :e, the cope 1 being It is particularly flask as the mold is com ranged to pass. The lower end ithe rear vextending-flange 5. This flange 5 is provided with a V-shaped'groove 6, thisgroove and flange forming a pin guide formation.

The drag 2 :11. o has each end provided with a drag plate of the nature shown at 7, this plate being further provided with a series of apertures 8 by means of which it may be attached to the flask. "Adjacent its upper edge and in slightly spaced relation thereto are outwardly projecting aws 9, these jaws being also slightly inclined toward each other and being so formed along their depth 'dimension to form a seat for the complementally shaped formation 10 carried upon an adjusting bolt 11. The lower portion of each of the drag plates is provided with an outwardly projectlng stud 12, preferably of polygoiial shape in cross section. This stud is d signed to snugly v fit a similarly shaped a ierture 13 formed -,in the enlarged base portion 14 on the lower part of the triangularly shaped pin 15. This pinis of the shape shown so that it may cooperate with the groove 6 of the cope plate and is further provided with a slot 16 through which the bolt 11 is arside of the pin'15 is formed-topresent a square shoulder, as shown'at 17, in order that it may cooperate with a nut 18, this nut and the butterfly nut shown at 19 cooperating to securely lock the pin 15 in 5 any desired position of adjustment on the bolt 11.

As is shown in F gs. 1, and 6, the squared .aperture 13 'is designed to snugly fit the square stud 12 uponthe drag plate so that no relative circular'adjustment of the two cooperating parts will 'be necessary when assembling and in. order that the pin may be rigidly held in any position on this stud, the jaws 9 are provided to receive the com plemental formation 10 upon one end of the adjusting bolt 11. Because of the polygonal shape of the stud 12, the pin is normally are likely to become broken when the sand is knocked'out of the flask afterthe casting" operation. To. accomplish this, all that is necessary is to unscrew the butterfly nut 19,

'* slightly more the bolt 11 within its slot 16 in the pin itself,- in order that it may be removed from its positionof engagenientwith the jaws 9 on the drag plate and then remove theentire pin structure by withdrawing it from the stud 12. The jaws 9 are in slightlyispaced relation'with the top .of the drag plate, in order that the bolt 11 may be thus slightly elevated to cause its disengagement. I 1

A slightly modified type of construction is shown. in Figs. 5 "and 7. In these figures, thepin 24. is shown as being .of' triangular form in section, as above and as being used in connection with cope and drag plates as already described, but has its lower end formed as at 21 to seat itself directly between the jaws 9 of the drag plate, thus dispensing with the bolt structure 11 and its cotiperating parts. This latter construction may be resorted to where the work is of suchclass that absolute coincidence between the copeand drag'is not essential.

his latter construction also permits the more ready removal of the guide pin to be used upon the next flask after the mold has bGQIlCOIIlPlQtQd, since it is held in connection with the drag plate only by the seat afforded by the jaws 9.-

What I claim,-is:

1. A dash guide and pin construction comprising a cope plate, a pin guide for1nati'on carried by saidplate, a drag plate, a guide pin, a pair'of outwardly project'- ing jaws on said drag plate, said jaws being inclined toward each other in spaced relation to form a seat, and means for'supporting said pin in an upright position.

2. A flask guide and pin construction comprising a cope plate, a pin guide formation carried by said plate, a drag plate, an outwardly projecting stud on said drag plate,-

a guide pin the lower portion of which is apertured to fit said stud, .j-aaws on said drag plate, and means arrangedf'to seat itself in said aws for locking said guide pin in any adjusted position on said stud. A

3. A flask guide and pin construction comprising a copeplate, a pin guide formation carried by said plate, a drag plate, and an outwardly projecting stud on said drag plate, a guide pin having a slot therein and having its lower portion apertured to fit said stud, jaws on said drag plate, and an adjusting bolt structure arranged to pass throughsaid slotand formed to seat itself between said jaws for locking said guide pin on 'said stud. I

4, A flask gitide and pin construction comprising a 001%; plate, a' pin guideforma tion carried by said. plate, a, drag plate, an outwardly projecting studof polygonal shape in cross sect-ion onsaid drag plate, a guide pin, the lower portion of which is provided with a polygonal aperture to snugly fit said stud, .and means for locking said guide pin in'any adjusted position on said stud.

5. A flask guide and pin. construction comprising a copeplate, a pin guide formation carried by said plate, a drag plate, an outwardly projecting stud -of polygonal shape in cross se'ctionon said drag plate,

a guide pin having a'slot therein, outwardly projecting jaws on said drag. plate inclined toward each'other, an adjusting bolt passing through the slot in said pin, jn'ieans for locking said pin in any adjusted position on said bolt, and a formation carried by one end of said bolt arranged to seat itself be-'
