JAMES SWAN, OF SEYMOUR, CONNECTICUT.
IMPROVEMENT IN MACHINES FOR FORMING LIPS OFVAUGER-BITS.
Specification forming part of Letters Patent No. 116,509, dated June 27, 1871.
` ing drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and whichsaid drawing constitutes part of this specification and represents, in-
Figure l, a top view; Fig. 2, a side view; Fig. 3, a top view as in the completion of the operation; and in Fig. 4, a longitudinal central section. This invention relates to an improvement in the machine for which Letters Patent were granted to me dated J une 9, 1868, the object being the forming of the lip on bits or angers, known as the Cook bit,77 to mechanically turn the lips up and over the dies upon which they are formed; and it consists in combining with a pair of crimpdies, having projections corresponding to the lips to be turned, a rotating mandrel with a slidingYY sleeve, which, when the follower, revolving, has pressed and shaped the end of the bit, the said sleeve will be moved forward, without rotation, to force the metal over the projections to the dies. I find in practice that itis impracticable to form the Cook bit by spinning-that is to say, by revolving a mandrel to draw, by its revolution, the metal into shape. This is owing to the peculiar shape of the (look lip, the extent to which the metal is turned over to form the gonge-lipbeing so much greater than in common square-lip bits.
a av are the projecting ends of a pair of crimpdies, which are held in a pair off jaws, A A, and moved to and from each other by a right-and-lefthand threaded screw, B, the said crimp-dies b eing of the form and size to correspond to the bit oranger on which the lips are to be turned, and the bit, after the twist is formed, is placed in these crimp-dies with the metal for the lip projecting. C is a mandrel arranged to revolve freely in a carriage, D, in line with the dies, and moving to and from the dies in suitable guides E E. The inner end of the mandrel corresponds to the external shape of the end of the bit to be formed,.as seen in Fig. 4. The mandrel is caused to revolve by the 4application of power thereto, and is pressed up against the blank to shape the end of the bit,` This is done by a cam, F, on a shaft, H, thesaid shaft being caused to revolve by a worm, I, on the mandrel working in a pinion, L, on the shaft; therefore, by turning the mandrel it is forced forward, revolving against the end of the bit. This shapes the end or door part of the lip. To turn the ends of the lip to form the gouge portion I arrange a sleeve, N, on the end of the mandrel, f
as seen in Fig. 4, which is held by aforked lever, P, and prevented from revolving with the mandrel by a trnnnion or trunnions, to which the said lever P is attached. So soon .as the mandrel has i shaped the door portion of the lip, the mandrel still revolving, the sleeveN is forced forward by the action of a cam, R, on the shaft H operating against the lever 3, carrying the sleeve in-to the 1position denoted in broken lines, Fig. 3; and in this operation the extreme portion of the lips is forced over onto the projecting dies, shaping the interior of the lip, the forward end ofthe sleeve being beveled or expanded outwardly to allow it to pass freely onto and turn the lips. It is found j that if the sleeve revolves it will draw this class of lips so much as to entirely defeat the object of the machine, but by this arrangement of the non-revolvin g sleeve the most perfect work is produced I do not claim as new the projecting crimp-dies or revolving mandrel; but
I do claim as'my invention- In combination with the projecting crimp-dies a ofand revolving mandrel O, the sleeve N arranged upon the said mandrel and held in position by one or more trunnions, towhich the lever P is attached, the said sleeve having a longitudinal movement imparted thereto through the lever P by means of the cam R, the internal front of the sleeve being beveled or expanded outwardly, the whole operating in the manner substantially as described.
