IMPROVEMENT IN T HE MANUFACTURE OF'SHOVEL-BLANKS.
Specification forming part of Letters Patent No. [90,055, dated April 24, 1877; application filed November 18, 1876.
- To all whom it may camera State of Pennsylvania, have invented a new and useful Improvementin the Manufacture ot' Shovel-Blanks and I do hereby deelare that the following is a full and eXact description thereof, reference being had to the accompanyig drawings, and to the letters of reference marked thereon.
My invention consists in constructng the shovel-blank with lugs for forming the straps, the inner face or wall of said lug being cast against wrought-iron, so as 'to form a union therewith in the process ot' casting the blank.
To enable'others skilledin the art to make and use my inventiou, I will prcceed to descrihe its construction and operation.
In the accompanying drawings, which form part of my specification, Fgnre l is a perspective View of theingot-mold' for casting my improved shovel-blank. Fig. 2 isa vertical section ot' the same. Fig. 3 is a face view ot' one-half of the ingot-mold. Fig. t is an edge View of the shovel-blank. Fig.5 is a face YGW of the shovel-blank.
In the accompanying drawings, A A represent the two halves of the ingot-mold, placed together in juxtaposition. B repre sente a wedge placed in the cavity g of the mold, for forming thelugs G C, for the formation of the straps for the handle of the shovel, und-also for forming the socket for the lower end ot' the handle. f represents the cavity in the ingot-mold for forming the blank for the shovel-blade. The cavity f mayextend to the bottom of the mold, as indicated in Fig. 3, when the blank is poured by inverting the mold, so as to have the molten steel flow into the space on each side of the Wedge B in the cavityg of the mold. When the blanks for the handle-straps are made separate from the body of the blank e, the mold is eonstructed with suitable cavities for receiving the separate blanks, which blanks may be made of wrought-iron or soft steel by any of the known means, and are placed in the cavites of the mold and the steel cast around them, so as to form a weld and union therewith. A thin Wroughtiron flat bar, of about three-sixteenths of an inch in thiokness, may be bent so as to fit closely to two of the wallsof the Wedge B, and as indicated by the dotted lines at D in Fig. 2, and placed in the mold, and the steel blanks cast by the pour-ing process, so as to form a Weld with the wrought-irou, Whereby the inner Walls of the lugs which form the shovel-straps will consist of Wroughtiron. The blanks are heated and Welded, or hanmered, or rolled in the nsual manner, and by the ordinary means. By constructing shovcl-blanks as hereinbefore described, steel shovels may be constructed with great facility and economy of lahor, and at a diminished cost.
In practice, the mold for the blank should be heated, also the wedge B, and the wroughtiron bent around it. It Will be found that in the process of casting the blanks, it will be best to have the cavities g in the bottom part ot' it, so that in the process of casting it the molten steel Will fall with force on the heated wrought-iron D, and thereby form a perfect weld and union with the steel. The advantage of the union of Wrought-iron with the steel in the lugs G G, as herein described, will be apparent to the skilled roller or hammerman, and also to the Workman, in furnishing the shovel with its'wooden handle.
Having thus described the nature and construction ot' my improvement, what I claim as of my invention, and desire to secure by Letters Patent, is
A steel shovel-blank cast in one piece,
having lugs G O, and a cavity'for the reception ot' the lower end ot' the handle, the inner walls of the lngs being wrought-iron, substantially as herein described, and for the purpose set forth.
