IVIACHINE'FOR FORNING FINGER-RINGS.

SPECIFICATION forming part of Letters Patent No. 455,430, dated July '7, 1891.

Application tiled March 16, 1891.

To all whom it may concern:

Be it known that I, WILLIAM H. BECKHAM, a citizen of the United States, and a resident of Port Richmond, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Machines for FormingFinger-Rings, of which the p following is a specification.

The invention relates to improvements in machines for forming finger-rings; and it consists in the novel devices and combination of elements Vdescribed hereinafter, and particularly pointed out in the claims.

The machine sought to be protected hereby receives the ring or blank formed in the rough by dies or otherwise and transforms it into the completed ring of the outline desired. In the drawings I have illustrated the ringor blank in the rough and also the fmished ring. the niachineit is held on a spindle and caused to revolve rapidly in contact with and under the direct pressure of grooved rollers, which impart the form and finish to the ring.

The invention will be morefully under-` stood from the detailed description hereinafter presented, reference drawings, forming a part of this specification.

Referring` to the accompanying drawings, Figure lis a front end elevation of a machine constructed in accordance with the invention; Fig. 2, a top 4view of same; Fig.`3; an enlarged front elevation of same, the upper portion being broken away; Fig. 4, a vertical sectional view on the dotted line ft 4 of Fig. 3.l Fig. 5 is a detached vertical section on the dotted line 5 5 of Fig. 4. Figs.' 6 and 7 are detached sectional views of parts of the machine hereinafter specifically referred to. Fig. 8 is a plan and sectional View of the blank prior to its submission to the machine which is made the subject of this specification, and Fig. 9 represents a plan and section of the finished ring formed by the present machine from the blank illustrated in Fig. 8.

In the drawings, A B respectively designate the ends of the machine, said ends being connected by the tie-rods C and being se-` curely bolted to the floor.

The ends A B of the machine are provided with the vertically-elongated openings D, as

'illustrated in Figs..l and 4, which receive the NVhen the blank is submitted tobeing' had to the Serial No. 385,202. (No model.)

bearing-blocks E, in which are journaled the opposite ends of the driving-shaft F, which carries upon its front end, adjacent to the outer face of the end A of the machine, the grooved forming-roller G.

Over the driving-shaft F is arranged within the openings D the supplementary shaft H, which at its rear end is connected by the gearing I with the shaft F, and at its front end is provided with the spindle J, the latter being removable at will, as illustrated in Fig. 7, in which said spindle .I is illustrated as having a threaded inner end to engage acorrespondingly-threaded socket in the front end of the shaft H. The spindle J is made removable in order that a spindle of appropriate size maybe connected with the shaft H for rings of varying diameters.

Over the ends of the shaft H are provided within the elongated openings D the bearingblocks K, which are caused to firmly bear upon the shaft H by means of the bearingscrews L. It is obvious that by the operation of the screws Il .the bearing-blocks K may be forced upon the shaft H as firmly as may be desired.

The shaft F is provided at the inner faces of the ends A B of the machine with the collars'M, which operate to retain theshaft F in appropriate relation to the ends A B of the machine. The front end of the shaft H'is provided with the collar N, which prevents the shaft from moving forward through the end A, while adjacent to the rear end of the shaft H the end B of the machine is provided with the bowed plate O,which passes around the rear end of the shaft H, and is provided with the screw P, the point of which has a bearing against said end of said shaft H, and prevents the same from moving rearward through the opening D in the end B of the Y machine. By means of the collars M N and the plate O, having the screw P, the shaftsF H are retained in appropriate relation to each other-and to the ends of the. machine. shaft F extends outward beyond the ,end of the shaft I-I, and is provided with .the spurgear wheel Q, which is engaged by the pinion R, mounted upon an auxiliary shaft S, which receives the driving 4or belt wheels T, The wheels T are adjacent to each other, and the one nearer the pinion-wheel R is rigidwith The 1' TOO the shaft S, while the right-hand one of said wheels'T is loosely mounted upon said shaft S in the customary manner, the purpose being to provide means whereby thc belt may be shifted from the rigid wheel adjacent to the pinion R .in order that the operation of the machine may cease without stopping the engine or other motive power. The motion from the pinion-wheelRis imparted through the gear-wheel Q to the driving-shaft F,and this shaft through the medium of the pinionwheels I causes the rotation of the shaft Il.

Upon the front end of the shaft F,adjacent to the outer face of the front end A of the machine, is also provided a collar, and against this collar is arranged upon said shaft the revoluble ring V, which has the arm "W to receive the inner end of the link X, and against this revoluble collar V is arranged a duplicate revoluble collar Y, having the arm Z to receive the inner end of thelink ct. The collars V Y correspond in all respects with each other and their arms W Z extend upward and outward on opposite sides of the spindle J, as illustrated on an enlarged scale in Figs. 3 and 5. The collars V Y move easily upon the shaft F under the action of the links X a, which also correspond with each other and carry at their inner ends the rollers b. The outer ends of the links X a are connected, respectively, with the inner ends of the pivotally-secured arms d by means of the pins or bolts e, which carry the followers f, arranged to move in the curved grooves or guides g, formed in the front face of the end A of the machine. The jointed ends of the links X a and the arms d are connected, respectively, with the rods h, whose lower ends meet and are secured by means of a bolt i' with the lever j, the latter being secured on the bolt k and extending beyond the lower ends of the rods 7i a sufficient distance to afford a bearing for the cam m, pivotally secured at n and provided with the crank-'handle q, by which the cam may be operated at will. The cam m is provided with the rim 7' to receive the roller s, secured upon the upper end of the arm t, connected with the leverj. During the rotation of the cam m the roller s travels along the surface of the rim o", as indicated by dotted lines in Fig. 3. The purpose of the cam m and crank-handle q is to afford an adequate means for depressing the outer end of the leverj and thereby drawing downward the connecting-rods h and forcing inward the inner ends of the links X a for the purpose of bringing their grooved rollers h against the ring w while the latter is under process of treatment, as illustrated by full and dotted lines in Fig. 3.

As above mentioned, the spindle J is removably connected with the shaft H in order that it may be withdrawn and another substituted, according to the diameter of the ring it is desired to finish. rlhe grooved roller G is alsovremovably secured upon the front end of the shaft F in order that it may be Withdrawn and a roller having a groove ofl different size or form substituted, in accordance with the finish it is desired to impart to the ring. rlhe roller G is grooved to correspond with the exterior form it is desired to impart to the ring and is secured in place by means of the nut 00 engaging the threaded end y of the shaft F.

In the operation of the machine the blank illustrated in Fig. 8 is placed upon the spindle J, the shaft H having been elevated sufficiently to permit the insertion of said blank, whereupon the machine is set in motion, the cam m being turned downward, as indicated by full lines in Fig. 3, in order to bring the grooved rollers h against said blank with sufficient pressure to transform the blank into the finished ring illustrated in Fig. 9 Upon the blank being inserted over the end of the spindle J the screws L are crowded down upon the blocks K, thereby forcing theblank closely against the grooved roller G, while at the same time the operation of the camm, through the medium of the lever j and connecting-rods h, forces the grooved rollers b firmly against the blank at a point above the contact of the same with the grooved roller G. The machine being in motion and the mechanism being in the position just stated, the ring will be caused to rotate rapidly against the grooved roller G. and grooved rollers h, and be thereby by them duly finished in the form outlined by said rollers. The followers f move freely in the guidegrooves g, and hence the movement of the cam m will readily either elevate or depress the lever j and connecting-rods h. W'hen the cam m is turned upward to the posit-ion illustrated by dotted lines in Fig. 3, its rim fr will, through the instrumentality of the arm if, elevate the lever j and rods h, and thereby force the outer ends of the links X a upward and withdraw the rollers b from contact with the ring fw, at which time, the screws L being loosened, the shaft H may be readily tilted upward sufficiently to permit the withdrawal 'of the finished ring.

The collars V Y are of importance, since, as may be readily seen from Fig. 3 of the drawings, they afford a substantial bearing for,

IIO

the inner ends of the links X a and at the same time permit them to be moved toward or from the ring w. The collarsVYare close against each other, and hence in Fig. 5 the collar Y appears in full, while the collar V is hidden from view, being directly in rear of the collar Y.

It is apparent that the pressure brought against the ring is entirely under the control of the operator, since the cam m may be turned to and held in the position desired. The operation of the cam m may be easily performed by the attendant and its action, combined with that of the rods 71., arms d, and links X a, is such that a positive pressure may be maintained or quickly varied or released against the ring w.
