Specification of Letters Patent.
Application filed January 21, 1907.

Serial No. 353,267.
lb all whom it may concern:
Be it known that we, Mivrr KJnLs'rAo and SVEIN KJnLs'u-m, subjects of the King of Norway, residing at Stanwood, in the county of Snohomish and State of \Vashington, have invented certain new and useful Improvements in Rope-Making Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to machines which through the twisting and laying of a number of strands produce rope; and its object is to provide a machine of this character which will be of a simple, inexpensive and durable construction and yet capable of forming rope of a very high g *ade.
\Vith these and other ends in view, the invention consists in the novel construction, adaptation and combination of parts, as will be hereinafter described and claimed.
In said drawings, Figure 1 is a front elevation of apparatus embodying our invention; Fig. 2, a plan view; and l ig. 3, a fragmentary loi'igitudinal section of the same.
The reference numeral 5 represents the machine frame, which may be of any suitable form or construction. Journaled in bearing boxes on the frame is a shaft 6 which is driven from any suitable power source as by a belt upon the shaft pulley 6. l ixedly mounted upon shaft 6 are grooved pulleys 7 and 8 adapted to transmit rotary motion to the operative parts of the machine through endless belts or cables 7 and 8. At the front end of the machine is a vertical spindle 9 which is journaled in a suitable step bearing 10 and, through the medium of a bushing-sleeve 1.1, in a bracket box 10. The spindle terminates at the top in a conical end 9 and from which end to a short dis tance below the sleeve it is provided with a plurality of longitudinal grooves 9 through which the rope strands are conducted during the progress of the work. l ixedly secured to the spindle is a grooved pulley 12 and a spider-shaped member 13 which are bored respectively as at 12 and 1.3 to receive and furnish bearings for the axles 14 and 14' of rotatable carriers 15 for the spools 16. Immediately below the pulley 12 is another pulley 17, of the conical or stepped type, desirably, which is mounted upon said spindle so as to turn independently thereof. Such motion is obtained by the aforesaid cable 7 which also serves, by engaging with the pulley 12, to rotate the spindle.
18 is a fair leading pulley to guide the cable to the respective grooves of the pulleys 12 and 17 and is arranged likewise to act as a tightencr for the cable by adjustably connecting its support 18 to the frame, as by a securing bolt 19 extending through the slotted foot 18 of support. The opposing ends of the pulleys 12 and 17 are recessed to provide a chamber 20 for the reception of a toothed pinion 21, lixedly connected to the pulley 17, and meshing with toothed-wheels 22 which are mounted upon the axles 1 1-, the latter being prolonged into the chamber 20.
The spools 16 have end axles 16 adapted to be seated in sockets in the lower end 15 and the apertured bosses 24 of spring arms 24: which are connected with the upright members 15 of the respective carriers. By this arrangement the'spools are detachably connected with the carriers and can be inserted or removed by simply bending any of the spring arms 2% upwardly sufficiently to withdraw the spool axle which is engaged with said spool socket. The spring arms likewise act frictionally against the contacting end of the spool to prevent the spools from unwinding too freely when tension is put upon the strands in being unwound therefrom.
The strand from each spool is led through holes 25 and 25' in one of the upright members 15 of the respective spool carriers to an axial aperture 1 1- in the upper axle 14, see Fig. 3, and is acted upon by a spring 26 secured to each carrier and made adljustable by means of a thumb-screw 26 for each.
From the apertures 14" the several st ands are conducted through the aforesaid spindle grooves S), and thence between the jaws 2T, 27 of a laying bar positioned thereabove and which jaws are scparably secured to each other by a saddle piece 28, and adjustably connected to the frame by a thumbscrew 28 engaged with a screw-threaded aperture or nut bedded within the frame. \Vithin each of the meeting faces of said jaws 27 is a plurality of opposing notches 27 of different sizes to accommodate the different sizes of rope being made, and which are brought into position to engage with the work by moving the laying bar member transversely of the frame. Upon the top of the frame is a standard 29 to which is.
tiltably connected, as by pivots 30, a U- shaped member 31, one of the legs of which terminates in a handle bar 31 extending through a hole 32 in a locking plate 32 provided with a slot 32 through which extends a bolt 33, whereby the plate may be secured to an adjusted height corresponding with the inclination of the member 31. Upon the other arm 31 of said member 31 is a segmental slot 31, concentric with the pivots 30, for a locking bolt 3% extending through the adjacent portion of the standard-29 to further secure the member 31 to any adjustment. The pivots 30 are desirably formed of the protruding ends of a shaft 30 carrying a peripherally grooved drum 35, and a similarly grooved drum 36 is fixedly mounted upon a shaft 37 journaled in the member 31. The purpose of these drums is to furnish means for stretching the rope previously laid by winding it back and forth between and about the drums a sutlicient number of times to insure ample contact to prevent slipping of the rope upon the drums as the latter are rotated. Rotation is given to one of these drums,as 36, by means of a gear wheel 38 upon its shaft 37'being driven by a pinion 39 upon a shaft 39, which in turn is. provided with a gear wheel 39 driven by a worm-11 upon the spindle 9, and desirably formed upon the sleeve 11. The rope being thus led from the layingbar and about the aforesaid drums. as clearly shown in Figs. 2 and 3, and stretched is conducted between two other drums, 40 and 41, and from thence to-apparatus for coiling. Of the last named drums, the drum 40 is formed with graded grooves through the proper sized one of which the rope is conducted as it leaves the machine, and is pressed into frictional contact with the drum 40 by the other drum 41 by the action of springs 42 connected to the axle 41 of the drum 41 and tending to draw it toward the shaft 40 carrying drum 40. Both of these axles are extended through upright arms 43 of the frame.
H is a pulley mounted upon the shaft 410 and is driven by a belt 8 from the main shaft 6.
In operation the strands are twisted to form the rope by the combined action of the rotary spindle and the planetary motion imparted to the spools in conjunction with the resistance due to the laying bar and the drawing effect produced by the " drums 35 and 36. The action of the drums 35 and 36 would, of course, be governed by the compactness with which a particular run of rope is desired to be laid, and is regulated through the speed which is given to the drum 36, and variable through changing the gear wheel 38 for another of different diameter. Furthermore the paying out of the strands can be more or less retarded to supplement any slight variations in the lay of the rope by adjusting the tension of springs 26, as before explained.
The range of work which this machine is capable of performing is from an extremely small cord to a rope of considerable size, and while a relatively large amountof rope may be manufactured by a machine as illustrated, the same frame work would serve for a number of individual rope-making devices and all utilizing the shaft 6 in' common.
What we claim, is
A machine ofthe class described comprising a supporting frame, a twisting mandrel mounted for rotation in said frame and having one end provided with a plurality of longitudinally extending grooves radially disposed with respect to the axis of the mandrel, a laying device mounted upon said frame and positioned adjacent the grooved end of the shaft and. associating therewith, a spider fixed to the mandrel and formed with spaced bearings, a stepped pulley surrounding the mandrel and carrying a gear, a pulley fixed to the mandrel and provided with spaced bearings in alinement with the bearings of the spider rotatable carriers interposed between the fixed pulley and spider and provided with journals extending through the bearings of the fixed pulley and further having axially bored journals extending in the bearings of the spider, gears carried by the journals which extend through the fixed pulley and meshing with the gear carried by the stepped pulley, spools rotatably mounted in the carriers, means for-simultaneously operating said pulleys and drawing means associating with said mandrel.
In testimony whereof we our signatures in presence of two witnesses.
