T at whom it may concern:

Be it known that WGHTOHN H. JANEWAY, J r., and CHARLES G. ROEBLING, J12, citizens of thellnited States, and residents of Tren-. ton, Mercer county, NewJersey, have invented certain new and useful Improvements in Braiding-Machines, fullydescribed in the larly to machines for braiding metal strips about electric cables, hose, and other similar flexible articles.

connection. It is to be understood, however,

that the invention is not so limited, as -thei improvements are also applicable with useful results to the braiding of other like matezo rials such, for example, as wires, cords,

threads, tapes, or other strands.

In the accompanying drawings, Figure l is an elevation of a metal strip-braiding machine embodying all the features of the pres- 2 5 cut invention, said machine including braiding mechanism, feeding mechanism for feeding the article to be braided, and power mechanism for driving said braiding and feeding mechanisms. Fig. 2 is a plan view of the 0 braidingmechanism proper. Fig. 3 is a sectional elevation, on an enlarged scale, taken on the line 3 of Fig. 2. Fig. 4 is a horizontal section on the line 4 of Fig. 1, illustrating particularly the mechanism for drivingthe 3 5 shuttles and the mechanism for vibrating the bobbin-strip guides, Figs. 5, 6, and 7 are detail views of the shuttles.

Referring to said drawings, 2 represents the base of the machine, and 3 abracket thereon, in which is journaled a power-shaft at, by which the braiding and feeding mechanisms are driven, as hereinafter described. Upon the base-plate 2 is also journaled the bobbin-,

provided. The upper ring or plate '7 is provided' with the required number of bobbinsupports, four being shown, each of said supportsconsistingof vertical standards or posts 10, having bearings 11 at their upper ends for shown, so that the bolt may be removed from the standards 10 whenever it is desired to remove or insert a bobbin. of bobbin-support will also serve the useful function of enabling the ease of rotation of the bobbin to be checked or regulated as desired, as the nut or. nuts on the bolts 12 may be screwed up, so as to bend the standards 10 7o inwardly against the ends of the bobbins, and

For ordinary purposes, however, a tension device such as the spring 14, secured at one end to thebobbin-carrier and bearing at the other end against the coil of braiding-strip-will be suflicient. The bobbin-carrier is driven in the direction indicated by the outer arrows in Fig. 4 by means of a bevel-gear 15 upon the driving-shaft at, which engages a like gear 16, keyed to the lower end of the sleeve or hub 5, as shown in Fig. 3. The bobbin-carrier is also provided with a circular raceway for the shuttles, which in the machine shown are independent shuttlesthat is, have no common carrier for supporting and driving them-the opposing faces of the upper and lower rings 7 8 being grooved for this purpose, as best shown in Figs. 3 and 4, so as to receive the upper and lower edges 0 of the back orsupporting plates 17 of the shuttles, which are curved horizontally, "as'shown inFigs. 4 and 5, to conform to the curvature of the raceway in the bobbin-carrier. These shuttle-plates 17 are driven in the opposite di- 5 rection to that of the bobbin-carrier, as indicated by the inner arrows in Fig; 4, by a series i of driving-Wheels, shown as consisting of pin- This construction 65 ions 18,engaging racks 19,formed on the plates 17, these pinions 18 being mounted upon the upper ends of shafts 20, journaled in vertical bearings on the plate 8 and provided at their lower ends with pinions 21, meshing with a large gear-wheel 22, concentric with and rotating in the opposite direction to the bobbin above-described driving mechanism; but the gear-wheels are desirable with heavy strands or where the strain is considerable for any reason. The shuttle-plates 17 are provided with inwardly-extending brackets 24, having slots 25 on their upper edges for receiving bolts 26, with which each bobbin-frame is provided and by which said bobbin-frame is secured to said shuttle-plate, the bobbinframes, by reason of this construction, being removable from their plates 17. The bobbinframe of the shuttle consists of a cylindrical casing 27, in which is mounted the shuttlebobbin 28, said casing 27 being cut away, as shown at 29, to provide an opening for the passage of the braiding-strip from the bobbin 28 to the braiding-point. This bobbin-casing 27 is also provided with a clamping device for maintaining the strip from the bobbin 28 undertension,this clamping device consisting of a bracket 30, secured to the casing 27 near the 7 opening 29 and containing a loose and removable clamping-plate 31, held in engagement with the strip from the bobbin by means of a thumb-screw 32, mounted in the bracket 30, as best shown in Fig. 4. The connections between the casing 27 and the supporting-plate 17 of the shuttle are such as to support the casing 27 in an upwardly and inwardly inclined position, as illustrated in Fig. 3, and this position may be varied as desired to braid the strips in longer or shorter spirals and in accordance with the feed by adjusting the angle of the bobbin by the bolts 26. On the forward side of the casing 27-that is to say, the side which is in the lead as the shuttles are driven during the braiding operationthere is provided a guard or clearing-plate 33 for engaging the bobbin-strips and assuring the passage of the strips above or below each other, in accordance with the run of the shuttles, as the case may be. The inner or upper ends 34 of these guard-plates 33 also furnish guides for the strips from the bobbins 28, as best illustrated in Fig. 2, so as to secure their proper position at the braidin g-point and prevent interference with each other. The bobbin-carrier is also provided with vibrating guides for alternately raising and lowering the bobbin-strips above and below the path of movement of the shuttles, so that the strips from the bobbins willbe interwoven or braided with those from the shuttles. These vibrating guides are preferably constructed so as to serve the function of positive take-ups for maintaining the bobbin strips under the proper tension during the braiding operation and during the movement of the bobbin-strips across the path of the shuttles. Each of these combined guides and take-up devices consists of an angular lever 35, pivoted at its inner end in a bracket 36, secured to the lower plate 8 of the bobbin-carrier and carrying at its outer end a swinging arm 37, connected by a pin-and-slot connection 38 39 to the end of a link 40, pivoted at its inner end to one of the standards or supports 10. The free end of the arm 37 carries a guiding-stud 42, around which the bobbin-strip passes to the braiding-point, as shown. The stud 42 is preferably adjustable on the arm 37, this result being secured in the construction shown by a longitudinal slot 41 in the arm 37, in which the stud 42 may be adjusted as desired to secure just the desired throw of the strips in accordance with the braiding action. As the lever 35 is rocked on its pivot its outer end and the arm 37 and link 40 will be moved alternately upward and downward into the extreme positions shown by full lines and dotted lines, respectively, in Fig. 3, and thus move the bobbin-strip alternately above and below the path of movement of the shuttles. It will be understood that as the lever 35, arm 37, and link 40 are moved down the arm 37 and its guiding-stud 42 will swing inward and upward toward the bobbin under the pull on the 'strip until it engages the under side of a projection on lever 35, so as to compensate for the movement of the lever 35 away from the bobbin, the pin 38 moving outward in the slot 39, while on the upward movement the upper end of the slot 39 will engage the pin 38 and force the arm 37 outward to act as a take-up for the strip.

The rocking movement of the levers 35 and connected parts is produced in the machine shown by stationary cam-plate 43, fixed to the base 2 of the machine by means of a collar 44, keyed to the hub of said cam-plate and provided with arms 45, secured to standards 40, extending upwardly from the base 2. This cam-plate 43 is provided with a camgroove 47, which receives bowls 48 upon the inner ends of radially-movable cam-bars 49, suitably supported and guided in the lower plate or ring 8 of the bobbin-carrier,and which at their outer ends carry racks which engage pinions 50, fast to the axes of the inner ends -of the levers 35. The cam-groove 47 contains as many cam-surfaces as there are vibrating bobbin-strip guides, the said cam-surfaces being equidistant from each other, so that during the braiding operation all of the bobbinstrip guides are simultaneously actuated in the same direction. As the bobbin-carrier rotates the rack-bars 49 carried thereby will be moved alternately inward and outward, and thus will rock the levers 35 and connected parts downwardly and upwardly, as shown in Fig. 3.

The article or form on which the strands are to be braided, as before stated, passes upwardly through the hub 5 of the bobbin-carrier and may be an electric cable, hose, or other flexible article or a mandrel from which the braiding is removed when made. The articleor mandrel so braided is fed past the braiding-point in the present machine by means of a drum 51, connected by a train of gears 52 53 54 55 56 57' 58 59 60 61 between said drum and the shaft 4:, as illustrated in Fig. 1, so that the braiding mechanism and feeding mechanism are driven from the same shaft. The speed of the feeding movement will depend upon the result desired and be adjusted according to such result.

From the foregoing description it will be understood that during the braiding operation the bobbin-carrier is rotated in one direction and the shuttles driven in the opposite direction by the driving-wheels 18 21 on the carrier, whichwheels in turn are rotated by the gear 22, which is driven in the opposite direction to that in which the bobbin-carrier rotates. As the bobbincarrier is thus rotated and the shuttles driven in the opposite direction the rack-bars 49, moving with the bobbin-carrier, will be moved alternately inward and outward by the stationary camplate 43, and'thus through the pinions 50 vibrate the bobbin-strip guides upwardly and downwardly, as before described, and move the bobbin-strips above and below the path of movement of the shuttles.

It will be understood that modifications may be made in the form and arrangement of parts in machines embodying our invention, and We are not to be limited to the exact construction illustrated.
