WILLIAM BAYLEY, OF SPRINGFIELD, OHIO.

MACHINE FOR MOLDING FENCE-POSTS.

SPECIFICATION forming part of Letters Patent No. 513,751, dated January 30, 1894.

Application filedFebrnary 11, 1893. Serial No. 461,934. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM BAYLEY, a citizen of theUnited States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Fence-Post-Molding Machines,

an enlarged scale of a portion of the same. Fig.3 is a sectional elevation of Fig. 2. Fig.

4: is a transverse'elevation of the same. Fig. 5 is a detail referred to hereinafter. Fig. 6 is a plan View, showing diiferent stages of the operation of molding and some modifications. Fig. 7 is a perspective view of a box or flask, which may be employed if desired in connection with the other mechanism. Fig. 8 is a sectional view of the mold and pattern therein. Fig. 9 is a similar view showing the pattern withdrawn and the mold ready for casting. Fig. 10 is a plan view of the cope adapted to form the top of the'mold. Fig. 11 is a perspective view in detail of a modification of the same. 7

Like parts are represented by similar letters of reference in the several views.

In the said drawings A A, represent a flask or pit in which the molds are to be formed. It is preferably arranged in the nature of a pit arranged along the side or other convenient place of the foundry and is provided at the top with a metallic frame A, having suit able cross bars a, at convenient points in the length thereof, the frame being provided with suitable engaging hooks or bails o by means of which, and the aid of blocks and tackle or other suitable hoisting device, the frame may be raised from the top of the pit and the sand, from which the molds are to be formed, removed and replaced as desired. The frame A, carries, in addition to the cross bars a, a

series of vertical standards B, (see Fig. 5 for detail) which extend upwardly from one side of said frame and are curved outwardly and provided at their upper extremities with an open recessed bearing b, adapted to be closed by a hinged latch b, pivoted at 19 so as to be turned back, as indicated in dotted lines in Fig. 5.

Arranged above the frame A, and parallel thereto, are suitable supporting ways 0 c, which extend the full length of the flask or frame and vertically above the same. Located on said ways 0 c, and supported thereon by means of supporting wheels 0 having grooved peripheries to engage said ways is a traveling frame D. This traveling frame is provided wi thvertical guides or ways d; betweenwhich is located a reciprocating head or hammer E,

the upper end of which is connected to a rope E, which passes over a suitable supporting sheave E at or near the top of the frame D, and thence downwardly in convenient reach of the operator. The lower ends of the ways 01, are connected by a cross bar (1, formed with a central opening or hearing adapted to receive a rod or shaft F, which projects upwardly through said opening and is connected at the top to a cross bar or head F, preferably formed in two parts and adapted to engage and be guided by the ways (1. This rod or shaft F, carries at the bottom and below the cross bar d, the pattern G,Which corresponds in shape and size to the base of the completed fencepost. Means are provided by which the head F, and the hammer E,

may be connected together or detached from each other, and an auxiliary hoisting device E is preferably provided at one side of the frame 01, and adapted to engage with a hookshaped projection E on the hammer E, to raise the same when drawing the pattern in the manner hereinafter more fully specified.

This connection preferably consists in a bifurcated L-shaped connecting bar F adapted to embrace the rod F, and engage below the head F, and be connected to the hammer E, by a removable pin F In operation the traveling frame D, together with the pattern G and its supporting rod F,

normally connected with the hammer E, is

moved along the ways until it is brought 0pposite one of the standards B. The latch 12,

is raised and the supporting rod F, of the pattern-is-placed within the recessed bearing 1), of said standard, after which the latch b is closed, thus retaining and guiding the rod F, in the proper position over the flask or pit containing the sand in which the mold is to be formed. The hammer and the pattern are now detached by withdrawing the pin F and removing the connection F The pattern is allowed to descend and enters into the sand in the flask or pit which has been previously prepared. The hammeris raised in the guides or ways by means of the elevating rope E, and is permitted to descend by gravity, striking the top of the rod F, and driving the pattern into the sand to the proper distance, afterwhich'the hammerE, and pattern G, are connected together, as before described, the auxiliary hoisting device E connected to said hammer and the parts elevated to their normal position, thus withdrawing the pattern -from the sand andleaving'the imprint of the said pattern therein.

-Thetop of the mold is closed and the upper part thereof formed by a cope. This cope may be'either formedby a chill, or may bema'de ofdr'ysand, formed and bakedin a core box afterthenature of a core, in the usual'manner. When the dry sand cope is employed, "an auxiliary frame or pattern is placed at the top of themain'pattern prior to withdrawing thesame and a print formed to receive the 'cope,which is placed at the top of the mold 's'oas' toform the upper part of the same after the pattern is-withdrawn. This cope ispreferably provided with an opening through; "which themolten metal is poured in casting itis also provided with a central opening; adapted to receive the post proper, which is? to'be m'ade of other metal and cast into the base. This is p'referably'formed of tubular m'etahcommon Wrought ironpipe being'pref-g erably'used. Afterthe pattern iswithdrawni and'removedfrom the supporting staudardB, thepostproper being first provided with'a tietachable collar 6 arranged at a suitable distance from the bottom thereof, is inserted 'ftliroughthe top of the cope so as to projectinto the mold to the proper distance andthe upper end thereof supported in the bearing inthe standard 13, as shown at the left of Fig. 1 when the mold is ready to receive the metal in casting. V

\Vhen the chill is employed an auxiliary framef, is preferably provided at thetop of "the flask or pit resting on the sand immediately uponthe pattern, this frame being adaptserted within the frame f, said chill being formed to fit snugly within said frame and provided with a suitable inlet opening g, for the metal, the detachable collar e, being provided for the inserted post e, as before described.

By the constructions above described it will be seen that the operation of forming a mold for a fence post is reduced to the simplest possible character. Any suitable number of molds may be formed, the supporting ways and the pit orfiask being extended as desired, and by the arrangement of driving and removing the pattern, together with the supporting ways and standards, the work is reduced to a simple mechanical operation, requirin g an ordinary mechanic and dispensing with askilled laborer usually employed in molding and casting articles of this character.

As before stated I preferably form the molds in the pit inthe floor ofthefoundry,withthe movable frame A, adapted to form the top thereof. It is obvious, howeventhata flask, such as shown in Fig. 7 maybe employed if desired and elevated above-the floor/the construction being'in no-wise changed in this case.

Having thus described my invention, I claim I 1. In a molding machine, a removable frame having a series of supportingstandardswith open bearings therein, a'travelingframe arranged on ways being paralleltosaidframe, a reciprocating hammer in said traveling "frame, a pattern also arranged in saidtraveling frame, and'means forcon'nectingand detaching said patternfrom saidhammer, substantially as specified. K

In testimony whereof I have hereunto set my hand this 4th day of February, A. D. 1893. 7

WILLIAM BAYLEY.
