.H; NNNNNN OR ATTORNEY Patented Oct. 15, 1929 UNITED STATES JOHN H. WARNER, OF FREMONT, OHIO MOLDING FLASK Application filed June 22,

This invention relates to a molding flask, the general object of the invention being to provide means for automatically causing the cope to assume its proper position on the drag as the cope is being placed on the drag, with means for aligning the sections of the cope and drag when the parts are being assembled so that the screws or bolts can be readily passed through the sections to fasten the parts together.

Another object of the invention is to provide clips for movably holding the sand bars or strips on the bottom of the cope.

This invention also consists in certain other 15 features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, ref- .erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the improved flask.

Figure 2 is an end view thereof.

Figure 3 is a bottom plan view of the cope.

1928. Serial No. 287,482.

Figure 15 shows a modification where but one pin is used.

Figure 16' is a View of the guiding means on the cope for such means. 1

In these views, A indicates the drag and B the cope, each part being composed of the side and end sections 1 which are fastened together by the bolts or screws 2 passing through holes in the abutting ends of the sections and the sections are automatically aligned when placed together to facilitate the placing of the bolts through the holes by means of the pins 3 engaging the semi-circular holes 4, a pair of which is formed in each end of each section, with one hole of each pair arranged at the top of the section and the other hole at the bottom of the section, as clearly shown in Figure 7 An angle-shaped base 5 is fastened to each end of the drag and a double pin 6 extends upwardly from each base, the pins being of double concave shape in cross section so as to form a groove 6 in the outer face of each pin. An angle-shaped bracket 7 has its vertical flange fastened to each end of the cope, the horizontal flange having an opening 7' therein through which the double pin passes. A pair of circular bars 8 is fastened together in spaced relation by the plate 9, the bars being cut away at their lower portions for forming shoulders to which the plate is connected. The outer portion of the plate is formed with elongated slots 10 for receiving bolts 11 which pass through holes 12 formed in the horizontal flange of the bracket 7 to ad- .7 justably connect the plate with the bracket. Thus when the cope is being placed on the drag, portions of the bars 8 will engage the grooves 6 of the double pins and act as guiding means for guiding the cope to its proper I position on the drag.

Instead of using double pins and a pair of bars 8, I may use but a single pin at each end of the drag, as shown at 6" in Figure 15 and use but a single bar 8 on the plate 9, as shown in Figure 16, to form the guiding means.

The sand strips or bars 13 is each pivoted at one end to the bottom of the cope, as shown at 14, and L-shaped clips 15 are fastened to the outer lower edges of the cope by the screws 16 and engage the strips to movably hold them in place. The strips are formed with notches 17 into which the clips pass when the strips are moved outwardly by means of their handles 18.

Thus it will be seen that I have provided a flask, the sections of which are automatically aligned when placed together so that they can be easily bolted together, with means for automatically causing the cope to assume its proper position on the drag as it is being moved downwardly on the drag, with simple means for movably holding the sand strips or bars to the bottom of the cope.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

It is to be understood that I may make changes in the construction and in thecombination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A molding flask comprising a drag and a cope, a guiding pin at each end of the drag having a semi-circular groove in its outer face, a bracket connected with each end of the cope and having an enlarged opening therein through which the pin passes, a plate.

adjustably connected with the outer part of the bracket and extending partly across the opening, means for adjusting the plate on the bracket and an elongated guiding member carried by the inner edge of the plate having a semi-circular portion for engaging the groove.

2. A molding flask comprising a drag and a cope, guiding means at the ends of the parts for guiding the cope to its proper position on the drag, sand strips pivoted to the bot tom of the cope and L-shaped clips connected with the cope and having portions passing under the strips for movably holding the strips in place.

In testimony whereof I afliX my signature.

JOHN l-L WARNER.
