To all whom t may concern Beit known that l, GUIDO HORN, a citizen of the German Empire, residing at Weissensee, near Berlin, in the Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Rope-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i
My invention relates to improvements in rope machines and the like, and more par ticularly in the apparatus for preventing twisting of the rope yarns which are being twisted to form astrand,or the strands which are being laid up to iorm a rope. And the object of the improvements is to provide an apparatus of this class which permits the use of the same elements in machines of different sizes, which does not require very exact iitting of the parts, and which can readily be thrown out of operation, when it is desired to twist the individual rope yarns or strands, as may be the case for example when twisting wires of particular cross-sections, or when applying strands as a covering to cables, etc. l
With this object in view my invention consists in mounting driving members such as sprocket wheels on the 'bobbin frames, and connecting the same by a flexible member or members with each other and with a driving member which is mounted coaXially of the axis of revolution of the bobbins, and which can be fixed in position, so that when rotating the frame on which the bobbin frames are mounted the bobbin frames are rotated in the opposite direction and in such a way, that each of the axes of the bobbins remains parallel to its original position.
For the purpose of explaining the invention several examples embodying the same have been shown in the accompanying drawing in which the same letters of reference have been used in all the views to indicate corresponding parts. p
In said drawing-Figure 1 is a side view of a frame which carries the bobbin frames and bobbins, Fig. 2, is an end view of Fig. 1 seen from the left, Fig. 3, is a side view of the apparatus for preventing twisting as applied in a braiding machine oit' the type shown in the patent of the United States to LundgrenNo. 695,746 granted March 18th,
1902, F ig. 4, is a plan view of the machine shown in Fig. 3, Fig. 5, is a iront view of a detail showing the device for throwing the apparatus for preventing twisting into or out of operation, Fig. 6, is a sectional view along line 5 5 of Fig. 5, and F ig. 7, is an end view similar to that shown in Fig. 2 and showing a modification of the apparatus for preventing twisting of the rope yarns or strands.
ln the drawing only so much of the rope machine has been shown as is necessary for explaining the invention. As the invention may 'be embodied in various forms of rope making machines or the like, and such forms are known in the art, a description of the machine is unnecessary.
In the example shown in Figs. 1 and 2, a rotary main shaft 3 carries a main frame or laying head l on which a plurality of bobbin frames 2 are rotatably mounted by means of shafts 4. Each of the bobbin frames carries a bobbin 5 which is adapted to receive the strands or rope yarns to be laid up into a rope or twisted into a strand, as the case may be. Each of the shafts 4 of the bobbin frames has a sprocket wheel 6 keyed thereto, and coaxially of the main shaft 3 a sprocket wheel 7 is loosely mounted on a trunnion 8 provided on the standard 9 which supports the frame 1, as is best shown in Fig. 6. Furthermore one of the shafts 4 carries a second sprocket wheel 10 which is disposed in the same plane with the sprocket wheel 7. The sprocket wheels 7 and 10 have the same diameter, and also the sprocket wheels 6 have the same diameter, and preferably the diameter of all the sprocket wheels 6, 7, and 10 is the same. On the sprocket wheels 7 and 10 a chain 12 is trained, and all the sprocket wheels 6 are connected by a common chain 18. The sprocket wheel 7 can be locked in position by any suitable locking means. To show what may be done, the standard 9 which provides a bearing support for the main shaft 3 is made with a bore 14, and the sprocketwheel 7 is formed with a similar bore 15 which is adapted to be brought in register with the bore 14 by rotating the wheel 7, and when the said bores Vhave been brought in register the sprocket wheel 7 can be locked in position by means oi a locking bolt 16 adapted to be passed into the bores 14- and 15. In a similar way one of the sprocket wheels 6 is provided with a bore 17 which is adapted to be brought into register with a bore 1S made in the frame 1, and the wheels 6 are adapted to be locked in position relatively to the frame 1 by means of a locking bolt 19 fitting in the bores 17 and 18. If it is desired to operate the machine in such a way, that twisting of the strands or yarns is prevented, the locking bolt 16 is put into posit-ion for locking the wheel 7, as is shown in Fig. 6. It now rotary movement is imparted to the main frame 1, the sprocket wheel 10 is rotated relatively to the main frame from the stationary wheel 7 and through the intermediary ot the chain 12. Such rotary movement is transmitted through the chain 13 to all the shafts 1 of the bobbin frames 2. After the main trame has completed one revolution, all the bobbin trames have performed a complete revolution relatively to the main frame 1, and such relative movement is opposite to the direction of the movement of the main frame, that is, if for example the main frame is rotated in a clockwise direction, as has been indicated in Fig. 2 by the arrow 22, the bobbin frames are rotated in an anti-clockwise direction. Therefore during the revolution of the bobbin frames 2 the shafts of the bobbins are always parallel to their original positions, or in other words, the strands coming from the bobbins 5 are not twisted during the revolution of the bobbins. It on the other hand it is desired to operate the machine in such a way, that the strands or rope yarns are twisted during the revolution of the bobbins, the wheel 7 is unlocked by removing therefrom the bolt 16, and the wheel 6 is locked in position relatively to the main frame by inserting the locking pin 19 in the bores 17 and 18. Now the rotary movement of the main trame 1 has no effect on the shafts 4, and the wheel 7 is idle on its shaft. It will readily be understood, that by providing the chains 12 and 13, and the sprocket wheels 6, 7 and 10 the bobbin frames 2 are positively driven from the wheel 7, so that slipping of the frames is impossible and each frame performs exactly one complete rotation for each revolution of the main frame 1.
In the modification shown in Fig. -7 a single chain 13 is provided for driving all the bobbin frames from the wheel 7. As shown at opposite sides of each of the wheels 6 guide rollers 25 are located which are in such positions, that the chain 13 trained over the Wheel 7 and the guide rollers engages in the sprocketsv of the wheels 6. The operation of the apparatus is substantially the same as that of the apparatus described withl reference to Figs. 1 and 2. If it is desired to prevent twisting of the strands, the wheel 7 is locked in position by means of the locking pin 16, and if it is desired to twist the strands while revolving the main frame 1, the wheels 6 are locked by means of the bolt 19. y The construction of the locking bolts 16 and 19 willV be understood from the detailV views shown in Figs. 5 and 6. y
To show, that my invention may also be embodied in machines of other class, I have illustrated in a diagrammatical way in Figs. 5 and 6 a braiding machine of the type shown in the patent ot' the United States to Lundgren, No. 695,746, granted March 18, 1902. It' it is desired to make braids of a considerable thickness, for example braids for hose made up of several tarred strands, or braids made from wire, the .outer strands are twisted in a similar way as the strands of the ropes. In the said braiding machine the drivingy member is provided by a spur gear 30 which by rolling on a toothed rack 3l guides the outer threads along a cycloidal path. As the threads are alternately guided along an edge in opposite directions/they are twisted during the rotation if the tension of the threads is high, which .is objectionable in themanufactured article. By providing means for preventing twisting, this objection is removed. As shown in Figs. 3 and 4t a central wheel 71 is connected by an endless flexible member, such for eX- ample as a chain 32, with a wheel` 33 which is fixed to a thread guide 34C and has the same diameter as the wheel 71. The threads are guided through apertures or slits provided in the guide 34, so that they are always in the braiding plane, and av good article is obtained.
While in describing the invention reference has been made to certain machinesl in which it may be embodied and to'particular constructions which in my opinionv serve the purpose best, I wish it to befunderstood,` that my invention is not limited to the embodiment in the machines shown in the drawings, and that various changes may be made in the construction'and general arrangement of the parts within the gist of my invention.
