LUCAS C. CLARK, OF PLANTSVILLE, CONNECTICUT.
Specification forming part of Letters Patent No. 128,790, dated July 9, 1872.
To all whom it may concern:
Be it known that I, LUCAS C. CLARK, of
Plantsville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Felly-Plate Dies, of which the following is a specification:
My invention consists of the improved construction of the die-block-to wit, providing the same with a slopin g recess or depression formed in the bottom of the concave dieas hereafter described.
In the accompanying drawing, Figure 1 is an end view of the dies and drop embodying my improvement; Fig. 2, a top view of said die Fig. 3, a vertical section of the same on linex w, and the drop over the same; Fig. 4, a plan view of a felly-plate blank; Fig. 5, a side view of a telly-plate as swaged and chamfered by my improved die; and Fig. 6, a transverse section of said plate.
A designates a drop or swage of V the form generally used for swaging felly-plates, and B a die provided with a semicircular groove, C, of the same general form and size as the face of the drop A. The groove C is provided with a recess or depression, a, of a depth about equal to the thickness of the metal to be operated upon, and of the form of a finished fell yplate. The sides or edges 1) b of the recess a are beveled or chamfered, as shown. By reference to Fig. 6, showing a section of the plate,
- it will be observed that the beveled edges or sides 12 of the die B, and b of the plate D, are nearly in a vertical line, so that the plate, when swaged, ,can be readily removed from said die, although formed in a recess at the bottom of the concave groove. The top of the die B is provided with the ordinary gauges c c.
The fiat blank D, Fig. 4, is placed over the die B against the gauges c 0, when the drop A is dropped or forced upon the blank D, forcing it into the groove C until the lower corners of said blank strike the beveled sides b b of the recess a, when the continued pressure of the drop H forces the metal of the blank into the recess a and causes it to assume the form of said recess, thus giving the plate the semicircular form, and also chamfering its edges b b at a single operation along the whole extent of its sides and ends.
My improved die difi'ers from those in ordinary use by the addition of the recess a, and by an enlargement of the face of the drop A corresponding to the depth of the recess a, so that the face of the drop A and concave groove C fit each other, as shown in Fig. l, the re cess a being sunk in the bottom of the groove C the full thickness of the finished plate.
Prior to my invention the corners have been chamfered either in the flat blank, Fig. 4, or by means of a file after the felly-plate is formed in the ordinary swaging-die.
The advantage of my invention is that the corners are chamfered along the whole extent of the sides simultaneously with forming the plate, thereby saving the extra labor and expense of an operation for the express purpose of chamfering only.
I disclaim the dies patented to F. B. Morse, April 16, 1872, and to Allison N. Clark, J anuary 24, 1871; but do claim 1 The die-blocks A B, when provided with the recess a. with sloping sides and ends 1), formed in the bottom or face of the concave groove C,
substantially as and for the purpose described.
LUCAS C. CLARK.
