MOLDERS-FLASK STAND.

Specification of Letters Patent.

Patented May 2, 1916.

To all whom it may concern:

Be it known that I, LEONARD Jonns'ron, a citizen of the United States of America, residing at Springfield,in the county of Hampden and State of Massachusetts, have invented a new and useful Molders-Flask Stand, of which the following is a specification.

My invention relates to improvements in rests or stands designed to support molders flasks while the metal is being poured into the molds contained in such flasks, and consists essentially of separate supporting members, a pair being sufficient as a. rule, and one or more, usually two, readily detachable beams, bars, or equivalent members mounted on said first-mentioned members, the latter being provided with rearwardly-projecting bottom members to prevent the stand from tipping over backward, all as hereinafter set forth.

Small flasks containing molds, especially those for brass castings, are generally raised more or less from the floor and grouped into as small a space as is convenient in order to facilitate the process ofpouring the molten metal into the molds, and the principal object of my invention is to provide a stand for the purpose of holding or supporting such flasks which is absolutely firm and stable, can not be upset, may be easily and quickly set up and leveled, and as easily and quickly taken down, occupies no unnecessary floor space when in use, and can be stored in a very small space when not in use. Better castings result from the use of this stand, because of the stability of all parts of the same, the central as well as the end portions, so that there is no sagging or springing at any point under the weight carried by said stand, and consequently no imperfections in the castings due to such sagging or springing. Thus it is clearly to be seen that the stand will carry safely any weight that may be placed upon it.

Another object is to provide a stand which is especially well adapted to receive a spilling trough, that is, a trough designed to catch any excess of metal that may be poured out,'when, as is sometimes the case, the flasks are placed on edge on the floor and leaned against the stand.

vMy stand is simple in construction and inexpensive to make.

Other objects and advantages will appear in the course of the following description.

I attain the objects and secure the advantages of my invention by the means illustrated in the accompanying drawings, in which Figure 1 is a top plan of a stand which embodies a practical embodiment of my in vention; Fig. 2, an end elevation of said stand, with a plurality of flasks thereon; Fig. 8, a rear elevation of the stand; Fig. 1, an end elevation of a stand having a level top, and, Figs. 5, 6, 7, 8, and 9 are end elevations of stands which embody various modifications.

Similar numerals designate similar parts throughout the several views.

It is possible to make up this stand in quite a number of different ways specifically, some of which are herein shown and described, while at the same time maintaining the same general construction, wherefore I do not desire or intend to limit myself unduly in matters of detail of construction, neither do I restrict myself in respect to size and shape.

Referring to the drawings it will be observed that the stand comprises a pair of transverse uprights or supports 1 and usually a pair of longitudinal beams, the latter being mounted on said supports and held in place thereon, as will hereinafter be more fully described. Each support 1 preferably consists of two posts 3 connected by a web 4:, and such support is provided behind at the bottom, or at the base of the rear post, with a projection or foot 5. The web 4: in each case may have a concave top, as shown at 6, to receive spatter trough 7, such trough appearing in Figs. 1 and 2. Each support 1 may have an inclined top, that is to say, the projecting top portions thereof or of the posts 3 may be inclined, as shown in the first three views, or such portions may be level and on a level with each other, as shown in the other views. The feet 5 prevent the stand from tipping over backward when loaded, it being in that direction only that there is liability on the part of the stand of being upset, or would be in the absence of said feet.

For the beams I prefer to employ T-irons 2, as shown in the first four views, since these are stronger and more rigid and stable 7 similar to the slots 8 than any other type of beam that would be suitable for my purpose. In other words, T-irons will not spring or sag in the center, and that is a very important factor in a device of this kind. Inclined slots 8 are provided in the posts 3, transversely of each support 1, to receive the ribs 9, of the T- irons or beams 52 employed in the construction shown in the first three views, and permit the beam flanges to rest on the tops of said posts. The slots 8 are necessarily at right-angles to the upper surfaces of the posts 3, through which said slots open at their upper ends, in order that the beams 2 or their flanges may lie flat on said surfaces. Similar slots 8 are provided in the Fig. 4 construction, except that here they are vertical because the top of the posts 3 are horizontal and the ribs 9 are at right-angles to the upper portions or flanges of the T- irons as usual.

As represented in Fig. 5, angle-iron beams 2 may be substituted for the T-iron beams 2, slots 8 being provided in the posts 3 to receive the parts 10, of the angle-irons, which correspond to the ribs 9 of the T- irons. The horizontal portions of the angleiron beams 2 rest on the tops of the posts 3. This type of beam can not have as much bearing surface on the supports 1 as the other type, and naturally is not as strong and stable.

The beams 2*, represented in Fig. 6, consist merely of flat bars, shallow slots 11 being formed in the tops of the posts 3 to receive and hold in place such beams. Even if reasonably thick the fiat bar beams are liable to sag, under a great weight, and by so doing to cause some distortion of the molds in the flasks above and consequent imperfections in the castings.

The stand represented in Fig. 7 is similar to that represented in Fig. 6, except that in the Fig. 7 structure fiat bar beams 2 are placed on the top surfaces of the posts 3, instead of being received in the slots 11, and said posts are provided with upwardly-projecting studs or pins 12 which pass through suitable openings in said beams to retain the latter in position. Flat bar beams 2 are also used in the Fig. 8 construction, but they are here positioned edgewise in vertical slots 8 in the posts 3, such slots being and just deep enough to receive said beams and support them with their upper edges on a level with or above the corresponding surfaces of said posts. These beams can present only narrow supporting surfaces for the flasks, and are inferior to the T-iron beams which combine all of the good qualities and desirable features of most if not all of the other types or forms combined. In the last view I show a single beam 2 which rests on both posts 3 and has two ribs 9 to enter the slots 8. This construction is less flexible than any of the double beam constructions, that is, the stand with the single beam can not be so easily and conveniently set up and taken down as can the others.

In setting up the stand illustrated in the first three views, or as modified in Fig. at, all that is required is to place the supports 1 in position at a suitable distance from each other, and mount the beams 2 on said supports, operations which are easily and quickly accomplished. The stand is as easily and quickly taken apart. The other stands, with the exception of that illustrated in Fig. 9, can be set up and taken down as readily as the first, and the operations are practically the same. In the case of the Fig. 9 stand, the single beam is more unwieldy than are the. two beams in each of the other cases, but the assembling and disassembling of the parts of said stand are quite similar, of course, to corresponding operations in connection with any of the other stands.

In Fig. 2 a series of flasks 13 arranged in three tiers isillustrated, such flasks being piled or stacked in the customary manner on the stand thereinrepresented.

It is clear that the T-irons employed with the vertically or approximately vertically slotted supports, besides affording the necessary strength and rigidity as horizontal or longitudinal supporting mediums, which with great facility can be placed in and removed from supporting position, form a connection of such a nature with said supports that the latter are held securely in parallel relationship and in alinement with each other.

WVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. A stand, of the class described, com prising separate and independent transverse supports having beam-receiving top parts, and provided with bottom end projections, and a longitudinal beam adapted to be superimposed on said top parts of said supports, said supports and beam being provided with means to prevent lateral displacement of said beam, without interfering with removal upwardly 0r adjustment longitudinally.
