To all whom it may concern:

Be it known that l, HENRY G. VOIGHT, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have un'ented certain new and useful Improvements in Snap-Flasks for Molders' Use, of which the following is a full, clear, and exact description.

.l-lv invention relates to improvements in molders' flasks of the cope and nowcl type, and more particularly to snap flasks, SID-Called. These devices comprise two companion upper and lower sections termed respectively the cope and the nowel.

With these sections top and bottom boards are used, but since these boards constitute no part of this invention, they need not be shown or described.

The object of my invention is to provide a simple. exceedingly durable and effective construction. aiming at cconoin of manufacture and maximum servicea ility. The construction also has the advantage of lightness. strength and comparative inexpensive- In the drawings Figure 1 is a perspective view of one section kin this instance the nope") of a snap ask (partly broken away) and constructed to embody m inven F i 2 1s a relatively enlar ed detail View of u guide-pin and socket for the cope and Bowel. Fig. 3 is a vertical cross-section of Fig. 2. Figs. 4; 5 and 6 are respectively sectional views of the same parts showing three diffcrent positions of adjustment. Figs. 7, 8 and 9 are respectively sideelevations of the Kiwis shown in Figs. 4, 5 and 6, said parts ing separated and broken away at the center. Fig. 10 is a pers iectire view of one corner of one section of t 1e flask illustrating details of construction and a slightly modified method of connecti Ir the corner connestions as compared wi t h that illustrated Fig. 11 is a View of the under side of the part shown in Fig. 9.

Since the cope and noweP sections of the flask correspond substantially in construction, detail dcscri tion of one section is sufiicient for a full un crstanding of my invention. One of these sections carries" a socketand the other a coacting whereby in use said cope and may be held together in roper o rative relation. Both sections opt-he flas are made from sheet or wrought metal, and each seei are interlockin guide-pin "the divided corners,- in this particular intion preferably comprises a plurality of overlapping plates constituting the side walls. in the drawings 1 have shown the side walls as composed of three late to wit. an upper plate 1, a lower p ate 2, and an intermediate plate 3 (see Figs. 4 to 9). These plates are correspondingly 'rooved or corn ated lon 'itudinally on their abutting sin aces, so that said corrugations will register or interlock one with another when the parts are placed together. By means of these corresponding corru tions, the manufacturer may make each o these three parts of a standard size, and by giving a proper pitch or spacing to the grooves or corrugations, may assemble the same so as to provide (with one standard set of plate? a flask section of several difl'erent sizes. or example, as shown in Fig. 4, the minimum sizeor depth is provided. In this figure, it will be observed that the, two ed es of the parts 1-2 practically abut. In fig. 5 they are spaced apart the width of one corrugation, increasing the depth of said flask section to a. oorres onding extent. In Fig. 6 the two edges 0? the parts 1-2 are spaced apart the width of two corrugations, furnishing a flask section of correspondingly greater depth. It should not be assumed that these variations in size are accomplished by the user (the molder) but the are rather an important and valuable exp ient of the manufacturer, who, in making said flasks, may, by the adoption of this standard arra-n ement of parts. readily produce flasks of ifierent dimensions. These sections 1. 2 and 3 are secured together at the corners. which corners may be and preferably are suitably mitered. and around which corners reinforcements 4 are secured, these corner reinforcements being suit-ably shaped to close the corners of each flask section to prevent leakage.

."|-5 are top and bottom plates, which are secured respectively to a top flan e 1 of each part- 1 and the flange 2 of one part 2.

All the parts may be secured togct icr by any suitab e fastenmgs, such as rivets 6-43. Each flask section is preferably divided at two 0 posite corners, one line of division being indicated at 7 1.

cvices provided for stance the interlockin" device 8 being in the form of a hook rigi y secured to one side of the flask section, while 9 represents a manuall operable hook pivotaily connected at 9 tot 1e adjacent side of the flask section, said hooks 5 and 9 coiiperating to interlock and hold the two sections of the flask in proper operative relation for use. bearing reinforcements will be, of course, provided to support the hooks 8 and 9, these being rigidly secured to the sections of the flask which respectively carry said parts. It may be assumed that the flask section shown in Fig. 1 is the cope, and to that end, followin the usual practice, a guide-pin is provided on this part. The ide-pin is of novel construction in that it, like the preceding parts, may be formed of sheet metal of a proper gage to withstand the strain of use and wear and tear. indicated at 10 and is struck up from wrought metal in such a manner that its rear T side appears as channeled, each side edge of each guide-pin being turned back, as at 10, and out along its ed e to conform to the cor rugated walls of a acklate 11. The corrugations of the back-p ate 11 preferably correspond to the corrugations in the side wall of the nowel section, so as to permit said part to be elfectively secured thereto. In the 11 of t preferred construction, the back-plate e guide-pin is provided at its front side with reinforcements 12-42, each of Suitable 3 This guide-pin is which are slotted at 12, said slots passing 5 through the back-plate to receive an attachin screw bolt 14, which passes through a suitable opening or perforation in the side wall of the co where said guide-pin is to be muted. y providing a slotted bolt pasage for each guide-pin fastening the guide-pin 10 may be readily adjusted up or down. The guidein construction is shown on a relatively en arged scale in Fi c. 2 and 3andthe method of fastening the gui epin to the back-plate 11 is best seen in Fig. 3, in which it will be seen the rear edge of the portion 10 of each guide-pin is provided with int 1 rivet extensions 1010" which are p s through perforations in the backplate 11 and are upset or riveted over to rigidlv and permanently secure the pin 10 to the backlate 11. The top of the guide-pin may be c osed in by a plate 15 secured by inte 'ral rivets 10 formed at the upper edge of tie parts 10.

The nowel section, which, as already explained, may corres nd to the cope section already described, is provided with a suitable socket to receive the guide-pin 10. The socket construction is best seen in Figs. 2 and 3, and may comprise tin-angular strucknp wrought metal portion 16 channeled at its back to embrace the guide-pin 10, and having turned-back rear edges 16* secured by integral extensions 16 to a back-plate 17, corresponding in function to the backplate 11 of the guide-pin. This back-plate bolt,

may have reinforcements 18-18 perforated or slotted and designed to receive screw bolts or other equivalent fastenings 19, whereby said back-plate and the socket proper 16 may be secured to the non-cl section. it?" is a friction spring, which may be struck in from the side of the socket 10 to frictionally press against the guidepin 10 when contained therein, to hold said parts snugly in frictional contact.

In Fig. 10, I have shown a slightlv modified form of corner reinforcement. In this view, it will be seen that the ends of the side pieces All of the flask section are not mitered, but are squared on, while the corner reinforcement C is corrugated throughout, said corrugations corresponding with the corrugations in the side sections .-\B to iegister and interlock with the same. These parts C are riveted thereto so as to make a permanent rigid structure. This figure will serve merely to illustrate that I comprehend that various modifications may be made in the construction without departing from the spirit and scope of the invention, said figure illustrating only one of the many modifications that may be adopted.

In manufacture, it will be seen that many economies are attained, since by the production of sets of standard parts the manufacturer may, without additional cost, produce a line of flasks of varying sizes and yet of comparatively the same minimum weight. By the employment of corrugated metal two advantageous ends are attained, to wit, greatstrength at a minimum of weight and expense, and a capacity for original adjustment to various standard sizes.

In use, the advantage of lightness and great strength and durability are cons icuous. Again, in use the corrugated wa of the flask sections permit the sand to be packed in in such a manner as to interlock ill the corrugations, thereby more firmly holdin it in place than in the case of a plain at sided wall against which the sand must adhere rather than interlock. in, in use, the danger of injury to the flas by coming in contact with molten metal is eliminated. Again, the structure is so rigid and firm that the danger of warping is avoided. Inasmuch as devices of this kind are subjected to the most severe uses, being Hung about the foundry, resistance to injury from this cause is another advantage strikingly characteristic of the construction describe-d.

So far as the use of the terms cope and nowel are em loved in the specification or claims, it shou d be understood that said terms are used interchangeably, for I appreciate that to a very substantial extent the advantages of my invention might be obmined if either one of said sections were constructed in accordance with my invention and the other section constructed in a different manner. Hence. in order to secure adequate protection. it should be understood that from the standpoint of construction, a
