DIEFOR FORMING SHOVELS.

SPECIFICATION formingpart Of Letters Patent No. 612,216, dated October 11, 1898. Application filed September 2'7, 1897. Serial No. 653,136. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM DAY Row- LAND, a citizen of the United States of America, residing in the city and county of Philadelphia, in the State of Pennsylvania, have the socket or handle portion being brought to its final form by the action of other dies or rolls of proper form. In all such previous mechanism, however, trouble has been met with, owing to the fact that the operation of the mechanism for completing the formation of the socket or handle has had a tendency to somewhat deform the blade, or, more particularly, to destroy the correct alinement of the socket with the blade; and the object of my invention is to provide mechanism for completing the formation of the socket or handle while preserving the perfect form and alinement of the different parts of the shovel and I accomplish this by providing, as ameans for closing the U-shaped socket or handle portion of the partially-formed shovel coming from the first die operation, a second set of dies having not only the usual form for closing the U shaped socket, but also blade-forming portions of substantially the same conformation as that of the first set of dies, in which the blade is brought to form and by means of which the previously-formed blade is at the same time that the socket is closed and completed pressed and held into absolutely correct form and correct alinement with the socket.

Reference being had to the drawings, in which my invention is illustrated, Figure 1 is a longitudinal section through the first set of dies, in which the blank is stamped to give the blade its proper conformation and to partially form the socket or handle. Fig. 2 is a cross-section through the blade-forming portion of these dies, taken on the line 1 1 of Fig. 1. Fig. 8 is a cross-section through the handle or socket forming portion of these dies, taken on the line 2 2 of Fig. 1. Fig. 4 is a plan view of the lower die. Fig. 5 is a longitudinal central section through the second pair of dies used by me in completing the formation of the shovel. Fig. 6 is a cross section onthe line 3 3 of Fig. 5, showing the formation of the dies at the point where the tubular socket or handle merges into the blade. Fig. 7 is a cross-section on the line 4. 4 of Fig. 5, showing the construction of the handle or socket forming portion of the die. Fig. 8 is a view of the dies on the same section-line 4.- 4, showing them closed together and the tubular socket completed. Fig. 9 is a perspective view of a shovel-blank in the condition it is broughtto by the first set of dies, and Fig. 10 is a perspective view of the shovel-blank in the condition it is brought to by the second set of dies.

The blank is formed in the usual way, with the proper allowance of metal for the blade and socket of the shovel, and is then placed on the lower die B, the portion B of which is that which forms the blade of the shovel, while the portion 13 is the male part, over which the U of the partially-formed socket or handle is bent. brought down upon the blank, the portion A coacting with the portion 13' of the lower die to form the blade and the female portion A coacting with the male portion B of the lower die to form the portion of the blank intended to be made into a handle or socket in the U form shown in Fig. 3. The partiallyformed blank having the conformation shown in Fig. 9 is then placed upon the lower die D, the portion D of which has the conformation of the portion A of the die A, while the portion D is adapted to receive and fit against the semicircular portion of the U of the partially-formed socket or handle. The upper die 0 is then brought down upon the blank, the portion C, corresponding in shape to the portion B of the die B, grasping and holding the plate in correct form and alinement, while the female portion G acts upon the legs of the U, turning them inward and, in connection with the lower die, forming a circular or The upper die is then cylindrical socket or handle, as shown in Fig. 10.

.Having now described my invention, What I claim as new, and desire to secure by Letters 5 Patent, is-

A die for closing a U -formed socket or handle of a partially-formed shovel having a completelyformed blade, said die having portions as C and D adapted to grasp and 10 hold the formed blade in correct form and position with respect to the handle part without changing the form of said blade and portions as C and D formed integral with said portions G and D adapted to close the U into tubular form.
