Description
PATENT GEEIOE JOHN HOBsON, OE PITTSBUHG, PENNSYLVANIA.
IMPROVEMENT IN THE MANuFAcTuRE oF HooK-EvEs.
Specification forming part of Letters Patent No. 186,437, dated January 23, 1877; application filed April 25, 1876.
To all whom it may concern:
Be it known that I, JOHN ROEsON, of .Pittsburg, countyof Allegheny, State of Pennsyl! Vania, have invented or discovered a new and useful Improvement in Manufacture of Hook- Eyes; and I do hereby declare the following to be a full, clear, concise, and exact description thereof, reference being had' to the accompanying drawing, making a part of this specifloat-ion, in whichlike letters indicating like parts- Figure 1 is a perspective view of the faces of the dies employed. Fig. 2 is a sectional view thereof', with the diesclosed together face to face. Figs. 3, 4, 6, 7 ,and 8 represent successive stages Or steps in the Operation of manufacture; and Fig. 5 represents a tool or device used in the operation.
My invention relates to the manufacture of wroughtiron hooks Or other like devices, in which an eye is desired at one end. Around rod is cut into blanks B, ofthe desired length, and a short portion, b, ofthe end is bent over, as in Fig. 3. This bent end is then flattened down, as at b', Fig. 4, preparatory to the forging of an eye therein transverse to the plane of flattening. For the purpose of forging this eye I'malce use of a pair of hammer-dies, `D D', and in each of such dies make a cavity, d' d', ofthe size and v shape of one-halt of the eye end of the hook to be made.` In the center of the round part of each cavity I insert the steel' die-pins t o. in such position 4that when in use their Outer ends will Operate in line withY each other, and shall be capable of comi-ng together end to end, or nearly so. These dies D D being arranged in connection with suitable machinery to give one or both a reciprocating motion, the flattened end'b is inserted along the cavity d', with the center ot' the dat part b directly in line with the diepins a a. Then, by a series ot' blows, the eye c isforged, the surrounding metal being spread out into the cavity d, so as to be properly shaped thereby; but in thus forming the eye a thin web Or wafer of metal, c, Fig. 8, will be left between the ends of the die-pinsc a. To remove this any suitable mandrel Or punch may be employed, one such (suitable to be set in an anvil) being shown in Fig, 5, Where e represents the mandrel. The eye vof Fig. 8 being placed on the mandrel e a blow Of the hammer will cause the web c" to be out out. The shank B then being brought against the post e', another blow of the hammer, or the hand-force of the workman, will give it the desired curve near the eye, as shown at g. Either thenor before I draw a point, g', on the end ofthe shank B by the use of the taper grooves h in the (liesD D', and then the end being bent, as shown in Fig. 7, or to any other desired form, the hook and eye is complete and ready for use. Y
The die-pins et et', may be made solid with the dies D D; but for convenienoeof renewal I prefer tO make them separate.
I claim herein as my invention- An improvement in the mode of making metallic eyes by folding over the end of the blank, flattening down the folded part, and forging the eye through the flattened part transverse to the plane of the flattened end, substantially as set forth.
` In testimony whereof I have hereunto set my hand.
JOHN EOBsON.
