F. E. MCC'ABE MOLD FLASK A Nov. 5, 1929.

Original Filed Sept. 19, 1925 4 Il n mi 4 lul- Ilm u ---4 7 l 3 HM .fm/wlan Patented Nov. 5, 1929 UNITED STATES PATENT oFFIcE FRANK E.MCCABE, OF CLEVELAND, OHIO, ASSIGNOR TO TI-IE GRABLER MANUFACTUR- ING COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO MIOLD FLASK Original application filed September 19, 1925, Serial No. 57,333. Divided and this application filed March 25, 1927. Serial No. 178,251.

This invention relates to an improved mold lflask. While many of its novel features make cation Serial No.f733,364, liled August 21,

1924 while the shake-out apparatus to which reference is made is disclosed in my first mentioned application, and in a division thereof iiled concurrently herewith.

The purpose of my present invention is to provide a very substantial and rigid mold flask, preferably comprised of an integral casting2 that is light of weight and especially suited for use in molding systems of the class referred to, and in conjunction with molding machines and shake-out apparatus of the kinds mentioned. y

To the ends in view I preferably cast the frame of the ask with as thin walls as practicable, and I reinforcev the walls with strengthening ribs, using by preference two ribs that are vertically spaced apart along the longitudinal sidesof the frameand connect them togetherl at their outer edges for parts -of their lengths with webs, thus effecting a tubular construction that is ex-l ceedingly strong and at the same time light;

and the end walls are strengthened'by-suit-- able rib arrangements which carry positioning means for properly aligning one flask with another when the flasks are stacked,v

and which incorporate supporting parts for cooperation with mold sustaining elements of the molding machine and shake-out apparatus. Y

In the accompanying drawing, Fig. 1 -is a plan view and Fig. 2 aside elevation of my improved flask; and Fig. 3 shows two of the flasks in end elevation and arranged one upon the other to illustrate the manner of stacking the flasks.

The flask comprises a rectangular frame v1 which is stiifened along each side by top and bottom flanges 2 and 3 that are connected together intermediate their ends by a web 4. This effects a sort of tubular formation for the longer sides of the Aflask which, while being light, is very strong. The importance of keeping the flask as light as practicable will be appreciated when it is explained Vthat the flasks have to be handled manually inv placing them within and removing Athem from the molding machines, and that several flasks at a time, stacked one upon another, have to be transported by a single carrier to the various stations of the molding system, and held suspended in similar arrangement by the shake-out apparatus.

The end walls 5 are strengthened by transverse flanges 6 which divide at their centers into top and bottom bran- ches 7 and 8, respectively, the former being provided with dowel pins 9 andthe latter with openings that are lined with bushings 10 designed to receive the dowel pins of the flask belowA when the flasks are stacked one upon another, -as illustrated in Fig. 3. The flanges 6 preferably extend about the corners of the' frame 1 to strengthen the frame in these regions. 1

Near the corners of the frame eachvflange 6 is reinforced or brac-ed by brackets 11, and-v yon its lower side is skirted adjacent each end walls 13 may be referred to as'socketsflll;

and it may be explained that within these sockets are adapted to engage the flask sus-; i .taining elements or arms of the inolding'machine, and the liftingA forks of the shake-out apparatus, the latter being guided into entering relation to the sockets by means ofthe inwardly converging walls 13.

From the'foregoing it will be seen that my invention provides a relatively light and a very strong and rigid mold flask that is especially suited for use with moldinginachines and shake-out apparatus of the character referred to; and attention is further .ofs-uperposed flasks.
