IMPROVEMENT IN THE MANUFACTURE OF SHOVELS.
Specification forming part of Letters Patent No. 152,583, dated June 30, 1874; application filled June 3, 1874.
To all 'whom it may concern:
- Be it known that I, JOHN T. TYLER, of Pittsburg, in the county of Allegheny and State ot' Pennsylvania, have invented a certain new and useful Improvement in the Construction of Shovels; and I do hereby declare that lthe following is a full, clear, and exact description thereof, reference being had to the accompanyin g drawings and to the letters of reference marked thereon.
The nature of my invention consists in the method, hereinafter described, of constructing shovels with a socket for the handle entirely external to the blade proper, and a bayoneti'ormed solid rib upon it where the' socket has generally been placed, said rib being integral with the blade, whereby strength and stiffness are imparted to it at the point Wh ere the shovel usually breaks, viz., at the socket, that part being, as it were, the fulcrum, and the use ot' rivets being dispensed with for securing the handle-straps to the blade.
To enable others skilled in the art to make and use my invention, I Will proceed to describe more fully its construction and operation.
In the accompanying drawings, which form part of my specification, Figure 1 is a top view or plan of the blank used in my mode of constructing shovels. Fig. 2 is a longitudinal scction of the same.
. indicated by the dotted line x.
A represents the parts of the blank which form the straps for the handle. B represents the part of the blank from which the shovelblade is formed. C represent-s the bayonetformed rib, which is solid, and gives strength and stiffness to the shovel at the point Where it usually breaks Off by long usage and heavy lifting, Which is generally at or near the place The irst step in my method ot' constructing shovel-blades is to cast ot' steel the blanks in the form represented in the accompanying drawings. The second step in said method is to heat the said blanks to a forging degree; and the third step is forging the parts A and B to the desired thickness, after which the blade is finished in the usual manner'. rolling device may be drawn down to the desired thickness.
That I claim as of my invention is- The hereinbefre-deseribed method of constructing shovels, viz., casting the blanks with the bayonet-formed rib C, and the external socket portion A, and subsequently heating said parts, and then reducing the blade and straps to the desired thickness by the forging process, as and for the purpose set forth.
JOHN T. TYLER.
