Application filed Janualy 13, 1912. Serial No. 671,073.

To all whom it may concern:

lie it known that I, \YILLIAM T. HAnnINo, a citizen of the United States, residing at Raleigh. in the county of \Vake and State of North Carolina, have invented certain new and useful Imrnovements in Casting Apparatus; and l do hereby declare the following to be a full, clear, and exact description of the invcntioi'i, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to casting apparatus and more especially to apparatus t'or casting sash weights, and has for its purpose to provide an apparatus wherein such weights may be cast in lots of the same or (litterent sizes, and wherein the mold parts are held in the most convenient position :tor the pouring and stripping operations.

The invention 't'urthcr proposes a mold of the character in question having a die mounted in such a manner that it will anallow contraction to take place in the cooling metal without tweaking out the eyc of the sash weight formed by the die.

With these and other objects in view the invention consists in the arrangement and emubination ot parts hereinafter claimed, and while the invention is not restricted to the exact details shown and described, still for the purpose of disclosm'e reference is bad to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which z- Figure 1 is a side elevation of the apparatus complete. Fig. 2 is a top plan view tl'icrect, partly broken away. Fig. 3 is a longitudinal sectirm view, partly in elevation ot the mold 72m" so. Fig. 4 is a detail perspective view ol one ol the die mcu'ibers and its adjusting rod. Fig. 7 is a detail sectional. view showing the die adjusting dcvicc. Fig. ('3 is a similar view taken at right angles to I ig. 5, and: Fig. 7 is an ele- Vatiou-o'l a part ol" the cast article.

ltclcrrimg to the construction in detail and with like chara ters representing like parts throughout the apparatus consists in a chair '1 having an upright: or supporting member 9 and a relativeiy higher supporting member 3 on which is mounted, through the medium studs 4- and 5. the mold proper which consists in an uppe and a lower section (5 and 7 respectively.

The mold sections (3 and 7 are each formedwith a pair of integral arms 8 (one of each being shown) that are connected by the bolts or hinges 9, whereby the mold sections may be readilyassembled and disassembled. 'lhc mold sections are each designed with a plurality of complementary recesses or chambers 10 which, when the lnold is assembled, conform to the shape of the articles to be ast. At one end these'casting chambers are restricted and have each an aperture or opening 11 communicating with a trough l2, which trough receives the molten material from the ladlev The chaml'icrs 10 are of their full diameter and extend for the full length of the mold, the purpose whereof being to receive. a die or follower which is adjustable within the chamber for the purpose of casting, sash weights of dilt'erent lengths as will be readily understood.

The dies or followers consist each of two members 13 constructed alike andalcsigncd to form the end ot' the weight, B in substantially that'shape shown in Fig. 7. The members 133 are each cut away at one end to receive the bars or rods 1-1 which are secured thereto by the rivets l5. and the length of said bars is such that the die may be adjusted to any position within the chamber 10. The rods H are each provided with a plurality of perforations 16 disposed at equal intervals, and which are adapted to receive the bolts 17 carried by the angle irons or brackets to that are in turn secured to the ends ol the die sections by the bolts l5) (see Figs. 3 and 5).

'lhc brackets 18 have the perforations 20 through which the bolts '17 pass, termed as a slot whose length is such that the bolts 17 may have slight movement therein, the purpose whet-cot being to permit ol. slighlt play of the die rods 14 so that the dies nlay be "free to move during the contraction of the metal while the metal is cooling and thus not break the eye a in the end A of the sash weight. in this connection itseems appro; priate to state that in molds of this charad tcr, as now employed. the dies for making the eyes in the sash weights are immovably sw-urcd after adjustment resulting in that the eyes are broken during the contraction ol' the metal, and which to avoid is one of the express purposes of the present; invention.

material the mold is supported on an in cline in the chair l by having the studs 4 When in position to receive the molten and 5 of the upper mold section supported upon the uprights 2 and 3 respectively and for holding the mold sections assembled and opening the mold, the lower section 7 is swung upon the hinges 9 through the medium of a lever 21. Said lever is fulcrumed on the stud 5 and has a 'web 22 in which is formed a slot 23 eceentric to said fulcrum, which slot receives a stud or pin 24 that is fixed to the lower mold section. Through the medium of the lever 21 and saidslot and pin engagement (23 and 24-) it will be readily seen that the lower mold section may be changed to either' of the positions shown in dotted line or full line in Fig. 1.

Since the apparatus is designed to cast weights of different sizes and it is desirable to mark each weight in pounds, the several divisions of the mold are each provided with a removable plug 25 which projects within the casting chamber 10 and which bears the numeral designation for its respective size 7 Weight.

What I claim is 1. In a casting apparatus the combination of, a chair having supporting members of different heights, a separable mold com- 'prising a pivotally connected upper and lower section, studs on said upper section resting on said supportsand' holding the mold on an incline, lever mounted on the uppermost of said studs and having a slot eccentric to said stud, and a stud on the, raised end. of the lower section engaging with said slot, said lever operable through said slot and stud engagement to raise and the same are adjusted to position, substantially as described.

3. The combination with a mold compris ing separable sections, of a die therefor, and means for adjustably positioning said die in the mold, said means comprising a pair of brackets secured to said mold sections and having each an elongated perforation,

rods secured to said die and provided with perforations; and bolts passing through the elongated perforations in said brackets and engaging with perforations in said rods;

said bolts and elongated perforations per- .niit'nng of'movement of said die after the same has been adjusted to. position, substantially as described.

Intestimony whereof, I affix my. signature, in presence of two witnesses.
