WVILLIAM GLADER, OF CHICAGO, ILLINOIS.

MACHINE FOR FLARING OR OONING BARREL-HOOPS- To all whom, it natty concern.-

Be it known that I, WILLIAM GLADER, a citizen of the United States of North America, residing inChicago, Illinois, have invented a new and useful Machine for Flaring or Coning Barrel-Hoops, of which the following is my specification.

My invention relates to improvements in hoop-flaring or hoop-coning machines in which former-blocks expand the unsupported edge of the hoop and press it against the supported edge of the hoop, whereby the hoop is held in an angle formed between the formerblocks, which produce the flare or coning of the hoop and the hoop-supporting arms. which resist the tendency of the hoop to advance and escape from the pressure of the former-blocks, theforrner-blocks. relative to the arms, and the entire mechanism producing a coneshaped hoop with an inverted base. I attain said ends by a mechanism which is substanstially such as is illustrated in the accompanying drawings, and in which-- Figure 1 shows my said new hoop flaring and sizing machine as seen on its top. Fig. 2 shows the same in central sectional elevation taken on the plane 2 2 of Fig. 1. Fig. 3 shows a central sectional elevation on a plane 3 3 of Fig. 2, which is at right angles to that taken on the plane 2 2 of Fig. 1, and shows the working parts of Fig. 2 in expanded position. Fig. t shows an expandingblock or former-block and its arm in plan view. Fig. 5 shows Fig. 4 in side elevation. Fig. 6 shows a former and its arm in plan view. Fig. 7 shows Fig. 6 in side elevation.

Like reference-letters denote like parts throughout.

The object of my invention is to produce a machinefor flaring or conically expanding cylindrically-formed barrel-hoops and wherein the act of expansion takes place toward the hoop-support, and thereby confines the hoop within an angle from which there is no possibility of its accidental escape, instead of expanding or flaring the hoop on its supported edge and without having any positive counteracting element, whereby it is left free to spring from the hold of the expanding-cone, and thus be troublesome, and whereby the function of the machine is limited instead of, as in my device, unlimited, as will appear hereinafter. v

In the drawings, Fig. l, there are shown Specification of Letters Patent. Application filed September 1, 1905. fierial No. 276,691.

Patented Dec. 12, 190? twelve expanding elements or members a, each one of which consists of a former b and an arm 0 at right angles to said former, and which preferably is in a horizontal plane and is reciprocable radially to the vertical axis of the machine. Each arm 0 is hinged at its outer end to the upper end of a link (Z by means of a bolt 0, and at its lower end said link hinges on a bolt 9, held between lugs f, which form an integral part of a ring or base A, on which said links hinge on said bolts 9, and said links are adjusted to place by means of a set of bolts, of which the bolt 2' passes freely through a large hole itand is threaded in the ring it, and under the heads of each of such bolts are placed large ball-and-socket washers Z, which receive and permit easy action of the bolt-head on said links, and the large hole Zr. through the link d, permits its free vibration. The bolts] are threaded in the link (Z, and their ends rest on and turn on the ring it. By means of said bolts 2' the upper end of the link or links is set in and out from the axis of the ring it and securely held in the desired' position, and thereby the former or formers b are set relative to the same ringaxis, so as to be able to work larger or smaller hoops m, Fig. 3.

Under the free end of each arm 0 is a roller a, and under said rollers is a horizontal disk or plate 0, which has a tubular axial extension 0, in which slides. a hollow piston, and in said piston is a screw 9, provided with a flange a, and above said flange the screw-shaft is smooth and turns in the plateo and is again threaded above said plate and provided with a nut 1 and above said nut the shaft is squared at r for the reception of a key or spanner; said nut serving to hold the plate against friction, which might otherwise overcome its weight. By the action of the screw q the relative position of said disk 0 to the formers and arms or the ring it may be set higher or lower, and thereby the formers b may be thrown in or out from the axis of the machine, and thereby the size of the hoop and at the same time the angle of its flare or coning may be increased or diminished.

When the plate 0 is set low or down within the top of the ring h, as shown in Fig. 2, the flare or coning which such position will produce on the hoops will be small, while, on the other hand, when the plate is set high above the ring it, as shown in Fig. 3, the coning will be relatively greater, as the reciprocating motion of the piston 99 will always be the same, as it is derived from a shaft provided with an eccentric or crank it, connected to the piston by a rod 25.

The supports of the ring h, the gear-wheels, and belt-wheels required are so plainly shown that they need no description, and they are parts which are not claimed.

For making a quick adjustment for difi'erentsized hoops I apply removable formerblocks '6, having slotted arms V, which fit into the angle formed by the arms 0 and formers Z), and are therein securely held by a bolt 6 passed through the slot 6* and threaded in the arm 0.

As the hoop m rests on the arms 0 and the flaring is made at the upper hoop edge, all tendency to slip from the formers is completely overcome, as the hoop is pressed into the angle formed by the connected parts 6 0, and thereby the capacity of this machine in this function is unlimited, and it is in thisparticular point that this machine is new and diiferent from all known hoop-flaring machines. The coned hoop cannot leave the formers until they are again returned to their original cylind rical position. There can be no accidental slipping of the hoop from the flaring mechanism, as heretofore, and which is often rather troublesome.

The formers Z) are free at their upper ends and in their normal position form a cylinder from which they may be moved to form a cone, as shown successively in Figs. 2 and 3.

What I claim is- 1. The combination with a series of cylindrically-placed formers, free at their upper ends, integral at their lower ends with pivoted, radial, and radially-adjustable arms, of means, with said arms, to move said formers into conical position.

2. The combination with a series of cylindrically-placed formers, free at one end and integral at their opposite ends with pivoted, radial, and radially-adjustable arms, said arms parallel to a horizontal plane, of mechanism to support the free ends of said arms, said mechanism reciprocable transversely to the plane of said arms, and adjustable transversely to the plane of said arms.

3. The combination with a series of cylindrically-placed formers, free at one end, and integral at their opposite ends with pivoted, radial, and radially-adjustable arms,in a plane, of mechanism to support the free ends of said arms, said mechanism reciprocable transversely to the plane of said arms, and adjustable transversely to the plane of said arms, whereby the degree of flare may be regulated, substantially as specified.

4. The combination with a series of cylindrically-placed formers, free at one of their ends, integral at their other ends with pivoted, radial, and radially-adjustable arms, formerblocks on said arms, said arms in a plane, of adjustable reciprocating mechanism to the free ends of said arms, to flare said formers, and supports for the hoop, said supports, with said formers, when coned, holding the hoop,fixedly, in an angle.

5. The combination with a series of pivotally-held and cylindrically-placed hoop-formers adapted to change from cylindrical to conical form, of hoop-supporting elements and mechanism to change said cylindrical into conioally-placed formers, whereby a hoop is flared and held between said formers and hoop-supports.

6. The combination with a series of cylindrically-placed formers, free at one end and at their other ends integral with pivoted arms placed in the same horizontal plane, and hoopsupporting mechanism, of mechanism to expand said formers at their free ends into continuously-increasing conical form.

7. The combination with a series of cylindrically-placed formers, free at their upper ends, integral at their other ends with arms placed at right angles to said formers, said arms pivoted at their outer ends and placed radially in a horizontal plane, of means to change said cylindrically-placed formers into an inverted'conical form.
