VILLIAM LECHLER AND J. K. SCHUPP, OF CLEVELAND, OHIO.l
IMPROVEMENT IN MOLD-BOXS FOR CASTING PROPELLER-WHEELS.
Specification forming part of Letters Patent No. 37,295, dated January 6, 1563.
[o all whom it may concern,.-
Be it known that we, WILLIAM LECHLER and J. K. SOHUPP, of Cleveland, in the county of Cuyahoga andState of Ohio, have invented certain new and useful Improvements in Mold- BoXes for Casting Propeller-Wheels; and we 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 accompanying drawings, in which- Figure l represents a top view of our improved mold-box for casting propeller-wheels. Fig. 2 represents a perspective view of a section thereof. Figs. 3 and 4 represent crosssections through said moldbox. Fig. 5 represents a perspective of a mold bed or block which we use in combination with the moldboX.
Our invention consists in making the mold of a propeller-wheel in sections, so that each wing or blade of said wheel may be molded separately. and that when molded the seotions may be iitted together, and when propcrly secured together will present a complete mold for casting a solid propeller-wheel- To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.
The entire mold, as represented in Fig. 1, is composed of sections A, one of whichis represented in Fig. 2, and which are fitted together by means of flanges a, and which may be `easily secured to each other by means ot' screwbolts b, or otherwise. Each section is intended to receive the mold of one oi the propeller wings or blades, and is composed of two iron frames, 1t and S, which are provided with ribs B C, between which the moldingsand is rammed in, in a similar manner as is done in ordinary mold-boxes. The two halves R S of each section A are secured together by means of langesd and screws g, or otherwise.
Fig. 5 represents a perspective view of the molding block or bed which we use in combination with the mold-box.
mold-block is worked out to correspond eX- actly with the side of the pattern to be used, said pattern being the exact counterpart of one of the propeller-blades, and being shown in red lines in Figs. 2, 3, and 4. One end of said block has suitable recesses for the reception of the inner end, E, of the pattern, which represents a part of the hub of the wheel.
The operation of this molding apparatus will further explain the particulars of the invention. The several sections A of the moldf box are detached from each other, also the two halves of each section or wing. The pattern is then placed on the mold block or bed and adj usted so as to rest thereon iirmly. Onehalf of the section A-i'or instance, the part S-is ,y
then placed upon the moldblock so as to cover the pattern, the flanges d of the mold-box resting on the edges of the block. The moldingsand is now iirmly rammed into the box inthe usual manner, and when that is donethe block, together with the pattern and mold-box S,are turned upside down. The mold-bed is then removed, and the other half, R, of the section A may now be placed on and fastened to the part S, the two being then in the position as represented in Figs. 3 'and 4, the patterns in the center being represented in red lines. The mold is then iilled with sand, which is rammed down tight, and thetwo halves beingA separated, the pattern may be removed, as in ordinary mold-boxes. This mode of molding the propeller-blades separately is repeated until all blades are molded, and upon the different sections A being secured together, as shown in Fig. l, they represent a complete mold from which a solid propeller-wheel may be cast without the use of any intricate cores, or without using laboriously built molds, which, when not perfectlydry, are liable to explode, and which require a great deal of skill, time, and experience to be made properly. By the application of these molds the cost of casting a propeller-wheel is therefore materially reduced.
It is obvious that a 1nold-box as herein described could not be used without the applicationl of the mold bed or block, as every part of the propeller-wheel must have its peculiar shape and position.
The application of the mold-bed secures the desired position of the pattern within each section ofthe mold-box, and the different sections being properly constructed, when tted together present the mold for the entire wheel. There can, therefore, no defect arise in the casting on account of the mold.
Having thus fully described the nature of our invention, what We claim herein as new, 2. In combination with the mold-box for a and desire to secure by Letters Patent, ispropeller-Wheel, as herein described,the mold- 1.
