Specification of Letters Patent.

. Patented June 3, 1913.

b all whom it may concern Be it known that I, W'uminn G. STA'PLFS, a citizen of the United States, residing at Newburyport, county of Essex, and State of bilassachusetts, have invented a new and useful improvement in Metal-Strand Machines, of which the following is a specification, reference being bad to the accompanying drawings.

This invention relates to machines for making metallic strands, filaments or bands in which the strands, etc. are formed by throwing a stream of molten metal upon a moving surface and in which the strands are arranged and assembled in bundles of suitable length and is an improvement of the invention shown and described in Letters Patent No. 989,075, dated April 11, 1911.

Metallic strands or filaments are employed to alarge extent in packing joints, valve stems and piston-rods and similar devices and when so used a large number of strands or filaments are bunched together in substantial parallelism or twisted into rope form. it is essential in such cases that the metallic strands or filaments be arranged substantially parallel to each other and the object of this invention is to provide means for arranging the continuous strand or filament, as it is thrown off the moving surface, into bundles of suitable length.

In the accompanying drawings illustrating the preferred form of my invention, Figure 1 is a plan view of an a paratus eonstrueted and operated in aecorc ance with my invention; Fig. 2 is a front elevation of the same, looking upwardly in Fig. 1; Fig. 3 is a side elevation of the upper portion of the same looking from right to left in Fig. 1; Fig. dis a detail elevation partly in section, on an enlarged scale of the means for feeding the molten metal to the moving surface to form the continuous strand, and Figs. 5 and 6 are detail views in elevation and plan respectively.

In the illustrated embodiment of the invention, the strand forming mechanism comprises a reservoir 7 for molten metal and a rotatable disk S. The reservoir may be supported in any suitable frame 9 on a table or bench 10 which serves as a supporting frame for the machine. Underneath the reservoir may be arranged a gas burner 11 to maintain the metal in a molten condition and the metal is delivered through a spout 12 to the edge 1 2 of the disk, the llow ol' the metal being controlled by a valve 14-. A gas burner 15 is arranged to heat the nozzle to prevent the metal cooling as it flows out. To permit of rotation of the disk 8., it is lnounted on a shaft it? supported at the base in a step bearing 17 and journaled in a boxbearing 1%, the shaft being provided with a pulley l9 which is connected by a belt 20 with any suitable driving means. The edge 1; of the disk is cut away to form a grooved channel 21. which in cross-section may be angular or curved to produce strands of varying form in cross-section. When the disk is rotated and molten metal is allowed to flow through the nozzle, it strikes the edge of the disk in the channel 21 and is cooled by contact therewith and thrown from the rotating disk by centrifugal force in the form of a continuous strand or fiber. The size of the strand is regulated by adjusting the valve in the nozzle to control the amount of flow of the metal and the shape of the strand in cross-section is determined by the cross sectioual form of the channel. By these means strands of various sizes and cross-sectional forms may be produced and the edge of the disk may be provided with a number of channels of varying cross-section, which may be used by adjusting the nozzle. As shown in Fig. 4-, the point of the nozzle is arranged in close proximity to the channel in the disk edge.

For the purpose of gathering and ar ranging the strand in substantial parallelism and in bunches of suitable length, I provide the following mechanism. On the table 1.0 is pivotally mounted at 22 a rod 23 carrying on its free end a downwardl y projecting hook 2 1 which is preferably spoon-shaped and curved inwardly. M ans are provided for swinging the rod around its pivot into the path of the strand as it is thrown from the disk 8, (see Fig. 1), and then back to carry the strand over a horizontal right angled rod 26 mounted in the front edge of the table 10 where the strand is deposited. Any suitable means may be employed for operating the swing ing rod 23 and one such device is shown 1n the drawings and comprises an eccentric 27 mounted on a shaft 28 supported in suitable bearings 29 on the table 10. The eccentric has a grooved perimeter 30 and the rod is "held in said groove by an upright spring rod 31 moving in a guideway 32 and connected to the swinging rod by a cord 33. The eccentric is operated from the'shaft 16 by means of

pulleys

34 and 35 on the shafts 1(3 and 28 respectively and a belt 36. The eccentric is so arranged that the swinging rod is above the disk 8 and oscillates over it to lay the strahd in a series of loops to form a bundle 37 on the rod 26.

In practice my machine is operated in the following manner. The

burners

11 and 15 are lighted and when the metal in the reser voir has been reduced toa molten state, the machine is started in operation by means of the belt 20 connected to the driving means. The shaft 16 and disk 8 are thereby rotated, the direction of rotation of the latter being in the direction taken by the strand 25 as shown in Fig. 6. By opening and regulating the valve 14 a thin stream of molten metal is allowed to flow from the mouth of the nozzle 12, which is in close proximity to the channel 21 in the edge of the disk, and

as the stream of metal strikes the moving edge of the disk'it is cooled, solidified and thrown therefrom in the form of a metallic strand or fiber which is continuous in form so long as the stream of metal is uninterrupted. As heretofore stated the size of the strand may be varied by changing the volume of flow of themetal and its cross-sectional configuration may be modified by using channels of various cross-sectional forms. As shown in Figs. 1 and 3 the strand thrown from the disk in a tangential direction and horizontally with considerable force. 7

At the same time. that the strand forming disk 8 is rotated, the eccentric 27 mounted onthe shaft 28 is turned by the belt 36 and thereby the rod 23 which is held in the groove on the perimeter of the eccentric by the spring 31 and cord 33 is caused to oscillate. The spring 31 is at all times under tension and maintains the rod in place against the eccentric. In Fig. 1 the full lines show the position of the rod when about to engage the strand 25 and the dotted linesshow its position after it has completed its oscillating movement and has dropped the strand on the support 26. As the rod oscillates toward the reservoir-thecurved hook 24 slides over the metal strand but when it returns the hook catches the strand and carries it toward the rod or support 26, permitting it to drop thereon as it (the rod) starts back toward the reservoir. Figs. 5

and 6 illustrate this operation and the manner in which'the strand is carried by the hook. During this operation the strand is being continuously formed and remains unbroken, the result being that it is hung over the support in aseries of loops as illustrated in Fig. 2. After a sullicient number of loops have been assembled together, the bundle is removed from the support and may be cut. The length of the bundle thus secured may be varied by changing the speed of the oscillating rod which may be accomplished by changing the relative sizes of the

pulleys

34 and 35.
