WILLIAM J. JOHNSON, OF NEWTON, ASSIGNOR TO HIMSELF AND HENRY A. HILDRETH, OF LOVELL, MASSACHUSETTS.

IMPROVEMENT IN CORN-POPPERS.

Specification forming part of Letters Patent NO. 116,600, dated July 4, 1871.

To all whom vit 'may concern:

Be it known that I, WILLIAM J. JOHNSON, of Newton, in the State of Massachusetts, have in- Vented certain new and useful Improvements in Corn-Poppers, of which the following, with the drawing, is a full description:

My improvements consist in a new method of constructing the binding and of attaching the screw-shank to the binding and the wire brace of the popper, as well as the construction of the screw-Shank for the purpose.

In the drawing, Figure lis an upper-side View of the screw-shank. Fig. 2 is a top view of the shank attached to the body of the popper. Fig. 3 is a section ofthe shank and wire brace. Fig. 4 is an under-side View Of a corner Of my improved binding. Fig. is a similar View of the old kind of binding. Fig. 6 is a side View ofthe Ol d binding as prepared to ben d and form a con ner. Figs. 7 and are sections of the binding attached to the wire Of the popper-body.

In the drawing, A represents the screw-sha1 ik; B, the wire brace; O, the wire cloth Of the body of the popper. D is the bindin of sheet metal bent over the top edges of the wire-cloth body, which is formed into shape by dies or otherwise. a. a are fork-like proj eetions ony the front end ofthe screw-shank. b is a brace or bar across the bottom and near the middle ofthe Open cavity, between the tines of the fork; and o is a brace or bar across the top and near the front Of this cavity. d is the rear end of the wire brace, which enters the cavity Of the screw-shank. e is the corner of the binding, Of which `f is the inside and h the Outside iiap.

In the Old-style poppers the inside flap f of the binding has a triangular piece, e, Fig. 6, cut out before the binding is bent to form a corner. When bent it appears as in Fig. 5. My improvement consists in corrugatin g the inside flap when the corner is bent without cutting it, as appears in Fig. 4. By this means the binding-edge Of the popper is greatly strengthened and stiifened at the corners. The binding is put on the wire body and fastened to it in the usual way. My screwshank is constructed with an Open cavity Or recess at its front, having a brace or bar, c, across its top, near the front ofthe tines a a, and another brace or bar, b, across its bottom, near the middle, forming a liind'of lnortise, into which the rear end d Of the wire brace B enters under o and over b. The front Of the screw-shank, which is of malleable metal, has two' fork-like proiections, a a, which pass through holes in the binding, and are clinched down, a-s in Fig. 2. In this manner the shank is iirmly attached to the body of the popper, and it also firmly holds the end d of the wire brace, which is slipped into the cavity of the shank. The brace is Otherwise attachcd to the body of the popper in front, in the usual manner.

l. The screwshank, with malleable ti nes a and brace b, substz'l-ntially as described.

2. The binding, crimped or corrugated at its corners, substantially z s set forth.

3. The combination of binding, wire brace, and screw-shank, sever-all constructed and arranged in relation to each other substantially as shown.

4. The corn-popper, with body, binding, wire brace, and screw-shank combined, when severally constructed and arranged substantially as described.

In testimony whereof I have hereunto subscribed my name.
