CORD-MACHINE.
SPECIFICATION forming part of Letters Patent No. 473,369, dated April 19, 1892. Application filed May 1, 1891- Serial No. 391,259- (No model.)
To all whont it may concern:
Beit known that we, GEORGE H. SPAULD- ING and FREDERICK L. MOORE, both citizens of the United States, and residents of Norwich, in the county Of NewLondon and State of Connecticut, have invented certain new and useful Improvements in Cord-Machines, which improvements are fully set forth and described in the following specification, reference being had to the accompanying three sheets of drawings.
Our invention is in that class of machines for producing braided cord in which a series of so-called travelers guide the bobbins around each other at stated times to interlace the several strands, the said travelers being controlled in their movements by a series of spur-gears revolving within an internal or ring gear, a familiar type of this class of machines being seen in Patent No. 20,690, issued to James Bazin June 29, 1858.
The object of our present invention is to so improve such machines that they may be more cheaply constructed, more readily repaired when their elementary parts become worn and unfit for further service, and also to provide a form of construction that will permit the machine to be operated at high speed.
In the annexed drawings, Figure l is in part a side elevation and in part a vertical sectional view of our newly-invented machine with the carrier-gears and bobbin-travelers removed. Fig. 2 is an enlarged view of the worm and gears that control the take-up as viewed from the left-hand side of Fig. 1, and Fig. 3 is a top view of said take-up. Fig. 4 is a plan view of the spider or disk that bears the series of carrier-gears and on which are located the segmental tracks which guide the travelers, and Fig. 5 is a central vertical sec tional view of the same on line at at. Fig. 6 is a top View of the internal or ring gear and of one of the carrier-gears in mesh therewith. Figs. 7 and 8 are respectively front and edge views of one of the bobbin-travelers; and Fig. 9 .is a lower end View of one of said travelers, showing the split foot which engages and is guided by the segmental track already referred to.
In the drawings, a indicates the base-ring of our machine, suitably supported on legs I) and adapted for use either on bench or floor. Extending upward from said base-ring is a cylindrical shell 0, to the upper portion of which is secured an internal gear d. (Shown detached and somewhat enlarged in Fig. 6.) Said internal gear is formed along its toothed edge with notches or depressions d, which occur at stated distances apart. A flange or ledge d projects inward beneath and beyond the ends of the teeth for a purpose hereinafter explained.
Extending upward from the center of the base-ring C6 is a hollow stud 9, whose lower end is turned down to fit an opening in said base-ring and is threaded to receive a binding-nut e. Secured to stud c is a horizontal bevel-gear f, that is engaged bya corresponding smaller gear) on a shaft g, that is supported near one end in a strand h and at the opposite or outer end in a yoke-bearing h. This yoke also supports a'second bearing h for the lower end of a vertical shaft 2', which transmits power and motion to the take-up, located above the machine and substantially like take-ups of many machines of this class. The lower end of shaft'o'bears a miter-gear i, that meshes with a companion gear on shaft g,thelatter named shaft being drivenbyabelt on fast and loose pulleys 7c 7a or by a suitable clutch-pulley. Secured to-the stud (2, above gear f, is a spider or disk m, whose upper surface is considerably below the level of the described internal gear. This spider, as here shown, has four radial arms, each being formed to receive near its outer end one of the series of carrier-gears '11.. These gears are like an ordinary spur-gear, except that they have notches or depressions n at distances apart corresponding to the notches of the internal gear. Referring to Figs. 4 and 5, it will be seen that plates 0 (of approximately oval outline) are secured to the arms of spider m by screws n and that studs 19 extend upward through said plates to support at their upper ends the carrier-gears a, one of said gears being shown at the right hand of Fig. 5.
Screwed to the outer edge of each of the plates 0 is a sheet-steel rib g, which forms the track which serves to guide the feet of the travelers, as also shown in Fig. 5. Two-thirds or thereabout of the track thus provided is concentric with the pitch-line of the carriergears; but the track at its outer sideis shaped as an arc of a larger circle and is left open to allow the passage in and out of the feet of the travelers.
The described enlarged arcs serve to grad ually force the neck of the traveler into and out of the notches n of the carrier-gears as the travelers are transferred or switched from the internal gear to the earriergear, and vice versa. This switching is in part effected by short guide or switch sections 3 8, located outside and opposite the plates and arranged in line with the ends of the track q, so that when the foot of atraveler seeks to pass from the end of track q it at once engages and rides on one of the short sections 3 s. The latter sections are held rigidly in place by screws 8 passing through a plate secured to spider m.
\Vithin the track q, opposite its opening, is an angleplate t, screwed to plate 0, having its outer face parallel with said track and forming a guard-rail to assist in guiding the foot of a traveler as it approaches the opening in the track 1.
' Vhen the machine is in use, the traveler is transferred from the notch of the carriergcar to the coincident notch of the internal gear, and there remains until the next carrier approaches and switches it out again. During this period of rest the traveler issupported by its neck in the notch of the internal gear; but to guard against accidental displacement of said traveler We provide guardrails a, substantially concentric with the internal gear and whose outer edges are adapted to engage the curved inner side 16 of the foot of the traveler, and so prevent the traveler from leaving the notch of the internal gear until the next switch engages it. It should be understood that the foot of the traveler is split to straddle the track q and short switchsections 3 s and that its inner side engages the guard-rails u. Said rails are secured to the spider m by screws to. Ve have referred briefly to a projecting ledge (Z on the internal gear. This ledge serves both to hold the carriergear at the proper level to engage the internal gear and also to assist in supporting the travelers as they are transferred from carrier to internal gear and back again. During this transfer the corners (l of the ledge project under the flange of the traveler and serve to support said traveler in its upright position: \Vere it not for ledge d the travelers would be liable to tip during such transfer, and in consequence relieve the constant tension of the strand of yarn.
The form of bobbin-traveler which we prefer to use is illustrated in Figs. 7, 8, and 9. A yoke or frame 10 is provided, having the neck 11 projecting downward therefrom and terminating with a disk 12, to which is secured a similar disk 13, having a rib 1 1. To the sides of said rib are secured by screws 15 steel plates 16 17, that constitute the foot of the traveler and are curved to fit the track q and guide'rails u, as already described. The bobbin proper is held on and between spurs 18 19, the latter being controlled by a spiral spring 20 and adapted to be forced upward to receive or release the bobbin.
The described method of forming the foot of the traveler forms a feature of our invention.
Our machine as a whole is simple, and its various parts are so designed that they may be easily assembled and adjusted.
\Vhat we claim as of our invention is 1. In a ln-aiding-rnachine, in combination, a notched internal gear, a spider bearing carrier-gears in mesh with the said internal gear, raised tracks detachabl y secured to said spider beneath the carrier-gears, a system of switches, as herein set forth, for transferring the travelers from carrier-gears to internal gear, and vice versa, and a traveler with a separable split foot adapted to engage the said track and switches, as and for the objects specified.
2. In a ln-aiding-machine, in combination, an internal gear, a series of carrier-gears rotating within and meshing with said internal gear, tracks and switches, as herein set forth, for controlling the movements of the travelers, guard-rails u, detach ably secured between the switches, and a traveler having a split foot adapted to engage the said tracks and switches, and also a curved surface on the outer side of said foot, the inward face of which is adapted to engage the said guardrails, all substantially as and for the purpose speci lied.
