Description
UNITED STATES PATENT Ormea E. F. HURLBUT, OF CHICAGO, ILLINOIS, ASSIGNOR TO,N. S. BOUTON, OF SAME PLACE.
EN'AIPROVEMENT IN PATTERNS FOR THIMBLE-SKEINS Specification forming part of Letters Patent No. 32,399, dated May 21, 1861.
To all whom t may concern:
Be it known that I, EDWIN F. HURLBUT, of Chicago, in the county of Cook and State of Illinois, have invented anew and useful Improvement in Molding Thimble-Skeins for Axles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, makinga part of this specication, in which- Figures l and 2 are vertical central sections of the iiasks and pattern, showing the process of forming the mold; Fig. 3, a detached longitudinal section of the thimble-skein.
Similar letters of reference indicate corresponding parts in the several gures.
The nature of my invention consists in the pattern used in making thimbleskeins, by which, while enabled to mold the same vertically, the cost of producing anincreased or decreased shoulder to iit different-sized wood Vaxles is much cheapened, and the method of adjusting. the green sand cores, so that they will be truly vertical, and thus produce a casting of even thickness.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
The thimble-skein pattern is made in two parts, A B, separated at the collar or flange i of the skein. The part marked A, I term the axle-pattern,77 and that marked Bthe butt77 or shoulder pattern, both together producing the skein-pattern in its perfect form. The advantage claimed and derived by this mode of making the pattern over all other modes, whether vertical or horizontal, is that frequent changes are made in the size of wood axles to be fitted with skeins; andheretofore it has been necessary,in order to suit all such cases, to have different patterns'. By my method an axle-pattern once made is sufcient for that size, and the butt or shoulder pattern alone is required new. This pattern is of small cost, quickly made, and thereby saves large expense for patterns over any other mode.
The follow-board C may be made in such form as any foundryman may choose to answer the purpose designed. I use two boards, a b, one raised above the other by means of studs c 0 to a height equal to the length of the axlepattern.
pattern, with a hole,` d, through the upper board, and under and immediately below the same, fast to-the'under board, a small casting, e, which fits the inside of the small end of the axle-pattern, having a hole through it of just the size of the points or cylinders used lin my cores, hereinafter to be described.
D is a metal rod, which has a cylinder, j, of enlarged diameter at its lower end, as shown in Figs. 1 and 2. This cylinder is pointed in conical form at its outer end, and at its inner end there is'a conical shoulder, It, which corresponds inversely in form to the upper beveled or flaring end, g, of the casting e.
The manipulation is as follows: The aXlepattern is inserted in this hole of the upper board, its end covering the previously-described casting below. Now place the butt or shoulder pattern B upon the axle-pattern A 4in proper position, place the butt-check C upon the follow-board C, and the self-adjusting core-barD and point or cylinder j dropped into the hollow of the pattern will assume a perpendicular position in the center of the This point or cylinder is of either castor wrought iron,(cast preferred,) varying in length and size with the size of the skein to be made, but is generally from one-half (t) to three-fourths of an inch in diameter, and from one (l) inch to three (3) inches long, shaped conical at its end, with a rod of iron one-fourth (i) or three-eighths (t) diameter extending from the base, which may be from two-thirds (t) the length of both patterns to even longer tha-n the patterns, as convenience dictates. A small rod is put into the hollow patterns, one end near the center ef the base ofthe point or cylinder above described, and
of sufficient length to extend through the bottom board after the different parts are molded.
Y Fill and ram evenlythe inside of the patterns flask in position after the parting made by the follow-board is completed. Upon the end of the axlepattern now exposed place tip of Wood or iron F, which shall forni when the casting is produced that part Where the thread is out, (designated by Z in Fig. 3,) the same having a hole in it to let through the point or cylinderj, previously mentioned. Rani up the flask and make parting at the top or small end of axiepattern- Ilace the cope G in po- Sition and rani it up in usual forni.
rEhe gates where the iron is poured I genoraliy piace in the center of iny iiask, pouring the iron into the mold at the band; but others may prefer a different method. Take off thecope and the tip F will lift with it, draw the same from the cope, take off the axle-check after having rapped the ends of the pattern to loosen it, draw the axle-pattern perpendicu` lar, lift the butt-check of the iask, draw the butt-pattern, the gates being eut, replace each division of the flask, and the work is coinplete. v
In case the green sand cores lean or incline from the center of the mold, the point by its peculiar shape will, when the cope is placed, force the core into its proper vertical position, and is by this means a self-adjuster to the green sand cores.
Having thus described niyinvention, what I elaiin as new, and desire to secure by Letters Patent, is-
Constructingl the pattern of two parts, A B, substantially as shown, so that different shoulder or butt parts, B, may be used with one andthe same axle part, A, as and for the purpose set forth.
EDVIN F. HURLBT.
