BLANK FOR MON KEY-WRENCHES.
SPECIFICATION forming part of Letters Patent No. 285,796, dated october` 1883.
Application filed April ll, 1883. (No model.)
To all whom t may concern,.-
Be it known that I, MATTHEW E. CAMP- FIELD, of Cleveland, in the county of Cuya hoga and State of Ohio, have invented a new and useful Improvement in Blanks for Forging the Hammcrdaws of Monkey-Wrenches, of which the following is a specification.
This improvement relates yto machineforg ing of the hammer-jaws of monkey-wrenches; and it consists in first forming the head of the blank with a narrow or decreased quantity of metal, where said head joins the shank and leaving the metal for forming the point and heel of the hammer enlarged, to be afterward wrought or beaten or pressed into nishedform inthe machine.
The object of forming the blank as stated is to facilitate the forging of the heels and points, and relieving the excessive strain on the dies in resisting the expanding of the metal at the central part of the head While forging the head with the old form of blank. This form of blank renders the forging of the heads with greater ease` and rapidity, and with greater economy of wear and strain upon the dies.
In the accompanying drawings, Figure l represents a completely-forged head,and Fig. 2
represents my improved blank from which the said head is forged. Y
the required length and swage up a portion thereof by gripping the shank portion between gripping-dies and forcibly upsetting the other part With suitable heading-dies into the form seen in Fig. 2. These blanks are next taken and placed in the machine for finishing the forging. The shank is gripped in this machine a short distance from the head. Then the operation of forging the heel and point is performed 'by beating down the projecting metal a into the forming-die, and also the. projecting metal b is beaten or forced into the die for forming the point, as seen in dotted lines. This operation also upsets a part of the shank, forcing it into the head, and thus makes the edges and corners of the head square and full, as seen in Fig. l.
Having described my invention, I claim- The herein-described blank for forging the hammer-jaws of monkey-wrenches, consisting of the head having reduced portion at its junction with the shank and the enlargements a and b, as and for the purpose specified.
