H. H. HUNTLEY. Pattern for Casting Stove-Leg Att'achme nt.
No. 209.811. Patented-Nov. 12.1878.

IMPROVEMENT IN PATTERNS FOR CASTING STOVE-LEG ATTACHMENTS.
Specification forming part of Letters Patent No. 209,811, dated November 12, 1878; application filed March 2, 1878. 1
To all whom it may concern:-
Be it known that I, Hosnn ll. HUNTLEY, of Quincy, in the county of Adams and State of Illinois, have invented anewand valuable Improvement in Patterns for Oastin g Stove-Leg Attachments; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 represents a sectional view of a stove-leg as it is applied to the attachmentlug. Fig. 2 is a sectional view of the pattern of the attachment-lug in the drag. Fig. 3is a sectional view of the drag, showing the curved branch of the pattern partially detached. Fig. 4 is a perspective view of the curved branch of the pattern.
This invention has relation to means for casting attachment-1n gs for stovclegs, evaporating-pans, sugar-boilers, and the like.
The nature of the invention consists in the construction and novel arrangement of a pattern for casting attachment-lugs for the legs of stoves and other heavy articles, said pattern having an upright lng branch and a separate detachable curved branch, as will be hereinafter more fully set forth.
In the annexed drawings, the letter A designates the bottom of a stove; B, the horizontal'arm of the stove-leg; (J, the eye-lug upon the stove-bottom, and D the key which confines the leg to the stove. The eye-lug (l is triangular in its general form, and consists of an upright pyramidal part, a, and a curved portion, b, diminishing in size from its connection with the plate A to its point of union with the upright portion. The curved surfaces of the portion 1) are regular arcs of circlcs, as'shown in Fig. 3.-
The pattern E, from which the bottom plate having the attachment-lug is cast, is formed in two parts.
The upright wedge-form projection to, which serves to prepare 'the mold for the east branch or of the lug O, is made entire with the plate portion A of the pattern, and is provided at its lower end with, an attachment notch or scat, e.
The curved branch I) of the pattern, which forms that portion of the mold in which the curved branch I) of the lug is cast, is detachable and of a circular or arc-shaped tapering form. Its lower end is formed with a projection, is, which engages with the notch e of the projection a. of the pattern; and its upper end is provided with a stud, s, which passes through an aperture, t, in the plate portion A of the l'iattern.
The two portions of the pattern being put together in the manner indicated, it is sunk in the sand of the drag in the usual manner to form the mold for the plate and lug. After the sand has been packed the plate portion A of the pattern is detached upward, leaving the curved branch I), which is afterward removed by a curved motion, the projection 8 serving as a handle.
Upon the plate portion of the pattern a smaller projection, 12, is formed in rear of the aperture t. hen the curved branch of the pattern has been removed the mold is ready. Molten metal is then, poured in, and the eyelug and stove-bottom cast in one piece.
In line with the lug is an angular catch, t, cast in the mold formed by the small lug v of the pattern, the function of which will be here inafter explained.
The under side of the horizontal arm B of the leg is made with a dished recess, a, at the bottom of which is a slot, 2, of suflicient size to receive the eye-lug; and it is provided with an angular recess, r, designed to receive the catch it upon the stove-plate A. This arm or plate is cast with the leg complete, and upon coming from the mold is ready for use.
The dish upon the under side of the leg branch or rm B greatly facilitates the attaehment of the leg to the stove, as it directs the eye-lug accurately to the opening of the slot 17. The bottom of the stove not being visible, this construction of the leg-bran ch or arm saves considerable time and labor. The leg being in position on the stove-bottom a triangular key, D, of the same conformation as the eye of lug G, is forced into the said eye, and offectually secures the leg to the stove.
It is evident that this device is applicable to evaporating-pans, sugar-boilers, and other metal vessels, and is of equal advantage.
What I claim as new, and desire to secure by hereunto subscribed my name in the presence Letters Patent, isi of two witnesses.
The pattern for casting attachment-lugs, HOSEA H HUNTLEY consisting of the main portion having the upright branch a, and the separate detachable Witnesses: 7 curved branch I)". substantially as specified. 1H K. RODOLF,
