Fig. 11 is an end case is a side flange a, under which the pointcutting die is placed and made adjustable and held against displacement by a screw let through a slot 16 in the flange. In the bottom of the casing is a central channel 17, in which the stem of the nail-ejector lies, and at the rear of the channel is a seat or slot Z), opening through the case to receive a stud on the stem of the nail-ejector. At the end of the channel 17 is a spring 18 to throw the ejector outward when the moving dies have receded.

O designates the nail-ejector and back piece. This consists of a metal stem 19, having a vertical stud 20 to takein the slot Z) through the case and carrying at its outer end a broad head-piece 21, having its back made to restin coincidence with the surface of the end of the casing and its face slightly curved in vertical contour to serve as an abutting-piece for the nail when pushed back by the bit of the moving case. At the rear of the stem the spring 18 bears against the stud 530, so that after the nail has been completed and themoving dies have receded the nail-ejector will be moved out and the nail discharged.

D designates the p0int-cutting dies. consist of two pieces of metal joined together bya lapped joint and a pin through the leaves of the joint. The rear portion 21* is a rectangular piece of metal in thickness intended to fit snug and flush in the seat made for it and serve as a liner in conjunction with the flange of the casing. In this part may be a series of threaded holes 26 to take a threaded bolt (not shown) let through the die-casing to hold the rear portion of the die fast in position. The front part 22, constituting the point-cutting portion, is, as stated, connected to the rear portion by a lapped joint 23 and a pin 2%, on which it has a limited play, and to elfect this play with certainty the outer face 25 of the lapped joint is made slightly curved. The part 22 is narrower throughout its entire length than the part 21 so that it may have lateral movement in the seat to effect the shearing movements on the point of the nail.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A point-cutting die consisting of two sections jointed together, the rear section being broader than the forward and point-cutting section, substantially as described.

2. A point-cutting die consisting of two sections jointed together by a lapped joint and a pin fixed in oneleaf of the joint and loosely projected through the otherleaf, substantially as and for the purpose specified.

3. A point-cutting die consisting of two sec Th cse tions, the rear section being broader than the forward or point-cutting portion and connected by a lapped joint and a pin fixed in one leaf of the joint and projected through the other leaf, substantially as described.

4. The combination of the die-casing formed with a side flange provided with a longitudinally-arranged slot therein, and a point-cutting die arranged in the casing under the flange and consisting of a rear portion and a front portion hinged together, the front portion being narrower than the rear portion, substantially as described.

5. The die-casing for the moving dies of a nail-cutting machine, consisting of a body formed with a channel in its side to take a gripping-die, a seat in the bottom for the nipper, and a seat for a point-cutting die adjoining the nipper-seat, substantially as described.

6. The die-casing for the moving dies of a nail-cutting machine, consisting of a body formed with a transverse groove across its face end and a back piece secured in the groove, a channel in its side to take the gripping-die, a seat in the bottom for the nipper, and a seat for a point-cutting die adjoining the nipper-seat, substantially as and for the purpose specified.

7. The combination, with the die-easing having dies arranged in its opposite sides and formed with a longitudinal groove in its bottom face, of a nail-ejector having a stem in the groove of the bottom of the casing and a head-piece on the outer end of the stem extending across the end face of the casing between the dies, substantially as described.

8. The combination,with the die-case having a groove in its bottom face, of a springactuated nail-ejector consisting of a stem to fit the groove in the case, and an ejector-head arranged to substantially cove rand set against the exterior of the end of the die-case, substantially as described.

9. The improved point-cutting die herein described, consisting of a rear broad portion and a front narrower portion united by a lapped joint and a pin, and the lap of the front part being curved inwardly on the outer face, substantially as described.

In witness whereof I have hereto set my hand in the presence of two attesting witnesses.

CHARLES E. IIOUGHTON.
