GEORGE VAN VAGENEN, OF NEr YORK, N. Y.

MACHINE FOR MANUFACTURING WROUGHT-IVIETAL. SWIVELS.

SPECIFICATION forming part of Letters Patent No. 443,807, dated December 30, 1890. Application filed August 13, 1890. Serial No. 361,981. (No model.)

To all whom it may concern:

Be it known that I, GEORGE VAN Wise- ENEN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and'useful Improvements in Machines for Manufacturing Vrought-Metal Swivels and other Articles, of which the following is a specification.

The invention relates to improvements in machines for the manufacture of wroughtmetal swivels and other articles; and it con` sists in the novel elements and combination of parts described hereinafter, and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure l is a side elevation, partly in section,

Y of a machine constructed in accordance with the invention, one side of the supportingframe ybeing removed and the section being on the dotted line l l of Fig. 2, which is a front elevation of said machine. Fig. 3 is a sectional view of said machine on the dotted line 3 3 of Fig. l and illustrating the blank from which the swivel is to be formed in position for manipulation; Fig. 4,a perspective view of said blank from which the swivel is to be formed; Fig. 5, a sectional View of said machine on the dotted line 3 3 of Fig. l and illustrating the parts of the machine in position f or performing the first step in the formation of said blank intol the swivel; Fig. 6, a perspective view of the said blank after having the ends of its transversebar bent downward in the manner denoted in Fig. 5; Fig. 7, a sectional view on the dotted line 7 7 of Fig. 8 and illustrating the position of the parts of the machine after the ends of the transverse bar of the blanks have been rolled or bent into their curved form; Fig; 8, avertical section of the machine on the dotted line 8 8 of Fig. 7 and illustrating the position of the parts of thel machine while concluding the operation of rolling or bending the downwardly-extending ends of the blank into their curved form; Fig. 9, a perspective view of the swivel after having been formed by the operations of the machine illustrated in Figs.

1 an'd`8; Fig.' lO, a side elevation of a detached portion of the machine, partly in section, showing the position of the parts thereof prior to the introduction of the blank thereto,

the blank' being illustrated by dotted lines; and Fig. 1l is a top ,View of same. Figs. 4, 6, and 9 illustrate the steps followed in the formation of the blank which is shown in Fig. 4 into the completed swivel presented in Fig. 9, and in these figures A designates the swivel-rod, and B the bar welded at its center to the lower end of said rod' and adaptedv to receive between its ends the customary wheel or roller. (Not shown.)

Referring to the figures of the drawings illustrating the machine, O denotes the driving-shaft, which will be supplied with the usual clutch mechanism (not shown)forstop ping it at the end of each revolution, so as to permit the withdrawal of thel completed swivel and the introduction of another blank, such as shown in Fig. et, before the parts vof the machine are again set in motion. The driving-shaft O is journaled in the frames D- D, which are of such design as to afford the requisite strength and permit the convenient introduction of the blank to and the withdrawal of the swivel from the machine, and

said shaft has mounted upon it the carriers E E, hereinafter described, one being on each side of the central frame F, which is iirmly secured by screws or bolts Gr and has upon its upper surface Vthe transverse bearing H and recess I, the former to receive the ,seg-

ment J and the latter the transverse bar B of the blank to be subjected to the action of the machine. The recess I has a slightlyconvex surface and at its ends meets therecesses L, formed in the oppositev sides of the frame F and adapted to receive the ends of the bar B after the same have been bent downward to the position shown in Fig. 5. At the front edge of the recesses L, which correspond exactly with each other, are the curved formers M, which constitute the front wall of said recesses and have an outline corresponding with that it is desired the ends of the bar B shall have when finally withdrawn from the machine. n

Upon the sides of the frame F are formed the curved ways N, through which travel the wheels O, hereinafter referred to, and in rear of the recess I the frame F is provided with the recess P to receive the toe Q, secured to or formed with the segment J.

The segment J is shown in its two positions by full lines and dotted lines, respectively, in Fig. l, and, as will be observed, said segment is provided with the groove R, which partly encompasses and has a hinged movement upon the bearing Il. The short arm S of the segment J constitutes a jaw to hold thebar B of the swivel-blank in the recess I, as shown by full lines in Fig. l, and is bifurcated, so as to straddle the rod A of said bla-nk, as clearly indicated in Figs. 3, 5, and ll. The short arm S of the segment J also carries the toe Q above referred to, which is cam-shaped, and in operation forces the bar B firmly against the front wall of the recess I during the lowering of said arm or jaw S, the purpose being to have the recess I large enough to conveniently receive the bar B and by means of the toe'Q to insure the Said bar being iirmly held preparatory to the action of bending and forming it. The toe Q protrudes below the lower surface ot the jaw or arm S, and hence it binds the bar B against the ,front wall of the recess I just before the force of the said jaw is brought upon it. Vhen the jaw or arm S is in its lower position upon the bar B, the toc Q is inclosed within the Arecess P, which is beyond the vertical plane ot the recess L, so thatI the toe Q will not obstruct the wheels O in the operation of curving the downwardly-extending ends of the bar B. The lower surface of the arm or jawS is slightly concave and corresponds in the line ot its concavity with the convex surface or base of the recess I, as shown in Figs. 3, 5r, and 7, whereby are formed at the opposite sides of the said jaw the downwardlydepending edges shown, which, upon the jaw being lowered upon the blank, iirst come upon the bar 13 prior to the ends of the latter being turned downward to the position shown in Figs. 5 and C. The convex base of the recess I and concave lower surface of the jaw S insure the formation ot the swivelwith the bar B slightly arched adjacent to 4the lower end of the rod A and its bends of a suitable curve to secure the requisite strength and rigidity therein.

The upperarm 'l of the segment J curves forward and is provided with the rounded teeth V, as shown in Fig. l, meshing with the similarly-toothed wheel W, having the side plates or ianges X and mounted on the auxiliary shaft Y, which is journaled in the frames D l), and has secured to one ot its ends the weighted lever Z, which is adapted to be swung by hand either to the front or rear, as shown by dotted and full lines, respectively, in Fig. l, and thereby to cause a definite rotation in the auxiliary shaft Y and toothed wheel lV and a consequent hinged movement in the segment J on its bearing Il. Ihen the lever Z is thrown or turned to the rear, as shown by full lines in Fig. l,the wheel \V,engaging the teeth of the segment J, moves the latter downward and forward on its bearing H to the position shown by full lines in Fig. l and closes the arm or jaw S upon the bar 2, and

when the lever Z is turned to the front, as indicated by dotted lines in Fig. l, it will reverse the movement oi' the shaft Y and wheel lV and cause the latter to turn the segment .I upward and rearwardon its bearing II, thereby elevating the jaw S from the swivel and leaving the latter exposed and free to be conveniently removed. The wheel XV, in addition to eiectin g the movement of the segment J on its bearing 1I, is in line with the said bearing, and hence prevents any upward movement of the jaw S during the operation of bending and forming the bar l5. Any tendency of the jaw S to rise under the action of the bar B is firmly and eiectually resisted by the wheel IV, which only permits the elevation and depression of the segment J'when the lever Z is turned by hand either to the frcnt'or rear, as indicated in Fig. l. The plates or flanges X on the wheel W insure the meshing ot the teeth ot' the segment J with those of the wheel at all timesand prevent any lateral play in the upper arm ofsaid segment.

The carriers E E have hubs Ct a., by which they are secured to the drivingshaft C, one of said carriers being on each side of the frame F, and upon said carriers are secured on suitable axes the rollers b b and wheels O O, as shown in Figs. l and 2. The rollers b l) are in the form of truncated cones whose axles d d are mounted in the bearings e, which are held in place upon the front surfaces of the carriers E E by the bolts or screws f, the latter passing through elongated slots z' A.in said bearings, so as to render the latter, with the rollers b @adjustable toward or `fromthe vertical faces of theframe F in accordance with the thickness of the bar 1B. Upon the outer face of the carriers E E are bolted the plates j, having set-screws m at `their ends, the purpose of the set-screws being to aidthe `screws j' in rigidly retaining the bearings c in place upon the carriers duringtheoperaltion of bending the bar B and vpreventany lateral or outward play in therollers b b while in use. The object of the rollers b bis to bend the ends of the bar B downward `from the position shown in Figs. 3 and 4 to that `illustrated in Figs. 5 and G, and their method of accomplishing this will be described hereinafter.

The wheels O O are mounted on axles `on the inner facing sides of the carriers EE and are provided with the annular grooves n, formed by the flangeszf a, the grooves being of sufficient width to snugly receive the thickness of the ends of the bar B after the rollers b b have turned said ends downward, and thc iianges u being of a depth equal or about` equal to the width of the bar l, so that said bar may, while being given the form shown in Figs. 8 and 0, have its ends within the grooves n and be prevented from twistingor becoming irregular under the action of .the'wheelsO O. It will be observed upon reference to Fig. 7 that the flanges u of the wheels O O travel IOO IIO

in and are inclosed above-and below by the ways N, formed in the opposite sides of the frame F, thus leaving thefannular grooves n in position to admit the ends of the bar B and bringing the main body of the wheels O O between the flanges t u in line with said ends of the bar B, the object being during the rotation of the carriers E E, with the driving-shaft C, to have that portion of the wheels O O between the flangesu come into contact with and curve the ends of the barB around the formers M, as indicated in Fig. 8, while the grooves n snugly receive said ends'and firmly hold them against twisting or other lateral play.

Preparatory to the use of the machine the bar B is welded to the lower end of the rod A, after which the blank in a heated condition is placed in the recess I, with the rod A extending upwardly centrally therefrom, the

p segment J having previously been thrown upward to the position shown by dotted lines in Fig. l by the movement of the lever Z and wheel lV. After the blank is in position the lever Z and wheel lV are reversed in their movements and the segment .l thus lowered, bringing the jaw S upon the blank, as shown in Figs. l and 3, whereupon the driving-shaft C makes one complete revolution and thereby causes the carriers E E to rotate in the line of a circle, following the direction of the arrow in Fig. 1, the effect being that the rollers b b are first brought against the ends of the bar B and bend them downward on opposite sides of the frame F, as shown in Fig. 5, and then that the wheels O O follow along and bend or curve said downwardly-bent ends of the bar B against the formers M, as shown in Fig. 8, after which the segment .l will be elevated by the lever Z and the now-finished swivel be removed and another blank inserted in the recess I preparatory to its formation in to a swivel by the next succeeding revolution of the driving-shaft C. At each revolntion of the driving-shaft C a swivel is formed by the rollers l2 b and wheels O O, and after being formed the swivels may receive the customary wheels or rollers between the ends of the bar B preparatory to their application to the front of a sugar-wagon, such as that shown in Letters Patent of the United States No. 428,790, issued to the George Van Tagenen Company May 27, 1890, or to any other article requiring them.

lVhere the two carriers E, with their rollers and wheels, are made useA of both ends of the blank may at one operation be bent and curved; but it is obvious that one carrier may be omitted and the swivel formed by first shaping one of its ends and then reversing it and shaping thev other cud, thus requiring two operations.

The single machine with but one carrier I do not consider as advantageous as the machine with both carriers; but it is to be understood that such machine is within the scope of my invention as claimed.

The -lever Z is weighted to facilitate the operation of the segment J, and said weight may be adjusted as occasion may require.
