nn'ira EDWIN E. SLICK, OF PITTSBURG, PENNSYLVANIA.
HOOP-BEADING MACHINE.
Patented Dec. 14, 1909. Serial No. 313,968.
To all whom it may concern:
Be it known that I, EDWIN E. SLICK, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Hoop-Beading Machine, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevation of a heading mill arranged for carrying out my invention; Fig. 2 is a sectional end elevation of the same; Fig. 3 is a top plan view; and Figs. 4, 5 and 6 are enlarged views of the successive passes.
My invention relates to the heading of the edge or edges of hoops, and is designed to provide a simple and improved apparatus for carrying out this operation rapidly and cheaply.
In the drawings, :2, 2, 3, 3 and at, t represent successive stands of two-high rolls arranged in tandem. These rolls are preferably overhung on one side of the housings 5 and on the roll shafts 6 between the housings are mounted driving pinions 7. Below the opposite ends of the shaft is a driving shaft 8 having a pinion 9 intermeshing with toothed wheel 10 on the lower middle roll. This toothed wheel 10 intermeshes with toothed wheels 11 and 12 on the upper rolls of the end sets. The rolls are preferably mounted in adjustable bearings, and the top rolls may be adjusted by screws 13.
The main feature of my invention lies in the bending passes to perform the beading operation. The first of these passes (4, shown in Fig. l, consists of a horizontal portion and a vertical portion connected to the horizontal portion by a curve. The length of the horizontal portion of this pass is such that one edge of the hoop will be bent over to form a flange at right angles to the body of the hoop, the entire length of the pass being equal to the greatest width of hoop desired to be bent. In the second pass 6, the groove in the upper roll is of triangular shape, and coacts with a projecting nose portion 14: of annular shape on the lower roll. These coacting portions of the rolls serve to bend the right angled flange of the first pass into an acute angled position with reference to the main body of the strip. Thus, the flange 15 which in pass a was at right angles to the body 16 is bent at an acute angle in the second pass, the body of the hoop being curved between the flanged edge 1 of the hoop and the opposite edge, the lower roll in this pass having clearance for the free bent edge of the hoop. In the third pass, the part of the pass formed by the top roll is preferably flat and horizontal; while the portion of the pass formed by the lower roll is correspondingly flat except for one portion wlnch is grooved in annular form to substantially the shape of the head. The flange coming from the second pass enters this grooved portion of the third pass, and is thereby bent into the form of the bead 17.
The metal hoop is preferably in all three. rolls at the same time, successive portions being shaped to the successive forms simul taneously, although each separate operation may be completed before the succeeding operation is commenced.
The advantages of my invention result from the rapidity and cheapness of the operation, and the correctness of shape afforded by the successive bending passes. The bead may be formed upon long lengths without cutting up into hoops, thus making the ma terial cheaper to handle, or the material may be cut into the lengths required to form a single hoop before being fed into the beading rolls.
Many changes may be made in the form and arrangement of the rolls, the driving connections, &c., without departing from my invention.
I claim 1. Apparatus for beading metal hoops comprising roll-s having a series of bending passes, the first pass being arranged to bend one edge of a flat metal strip to form a flange portion, the second bending pass being arranged to further bend the flat body portion of the strip between the flanged edge and the opposite edge of the strip and a third grooved bending pass arranged to form the bent portion of the strip into a marginal bead, substantially as described.
2. Apparatus for forming beads on metal hoops, comprising rolls having a bending pass arranged to bend one edge of a flat metal strip, a second bending pass arranged to further bend the flat body portion of said strip between the bent edge and the opposite edge of the strip and a third bending pass having a grooved portion in which the bent edge of the strip is further bent and is curved into and forms a. hollow marginal bead, substantially as described.
3. Apparatus for beading metal hoops comprising bending rolls having a bending pass 111 whlch one edge of a flat metal strlp 1s bent and a second bending pass arranged to further turn the bent edge 01: the strip and form a hollow marginal bead thereon substantially as described.
In testimony whereof, I have hereunto set my hand.
