SPINNING AND TWISTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 554,217, dated February 4, 1896.
Application filed May 27, 1895. Serial No. 550,818. (No model.)
To aZZ whom it may concern:
Be it known that 1, ROBERT DAWES, a citizen of the United States, residingin Philadelphia, Pennsylvania, have invented certain Improvements in Spinning and Twisting Machines, of which the following is a specification.
My invention consists of certain improvements in the spinning and twisting machine for which I obtained Letters Patent numbered 481,787, dated August 30, 1892, the objects of my present improvements being to automatically regulate the tension or drag upon the winding-spool, to automatically stop the machine when the spool has been fully wound, and to prevent the starting of the machine until the tension-regulating devices are in proper position. These objects I attain in the manner hereinafter set forth, ref erence being had to the accompanying drawings, in which Figure 1 is a longitudinal section of suflicient of the machine to illustrate my present improvements. Fig. 2 is an end view looking in the direction of the arrow, Fig. 1. Fig. 3 is a plan view of the tension-regulating mechanism with the frame and some of the other parts shown in section on the line 3 3, and Fig. 4: is a diagram illustrating a modification of part of the invention.
So far as regards the spinning and twisting devices of the machine and the devices for layin g the twisted rope properly upon the spool they are substantially the same as those of the machine previously patented, and hence will require no special description further than to say that the flier A is driven by a belt from a pulley A on the main shaft B, and that the flanged pulley a is carried by a sleeve which is connected to the spool and serves to retard the rotation of the same under the pull of the rope which is being wound thereon, said pulley receiving a belt a, which passes round a flanged pulley a on the shaft B, this pulley being so proportioned in respect to the pulley A that the spool is driven at a slightlylower speed than but in the same direction as the flier, the pulley a slipping under the belt a at a rate dependent upon the difference in the speed of the flier and spool. Hence said belt a serves as a frictional retarder for the spool. This frictional retardation of the spool should be slightest when the winding first begins andgradually increases in force as the spool becomes fil1ed,'and one of the objects of my invention is to effect such antomatic graduation of the friction, an object which I attain in the following manner:
The machine has the usual longitudinallyreciprocating frame D with guide for the rope, so as to lay the latter uniformly from end to end of the spool, and this frame has an arm D, which engages with adjustable collars d on a sliding bar d mounted in suitable guides in the frame and having ratchet teeth (1 adapted to engage with the teeth of a ratchetwheel f on a vertical shaft f, so that as the bar (1 is moved in one direction the wheel f will be turned forward thereby, a suitable pawl f preventing the ratchet-wheel from moving backward as the bar d is moved in the opposite direction, the teeth 01 of the bar then slipping over the teeth of the ratchet wheel.
By adjusting either or both of the collars CZ on the bar d the extent of movement of the bar on each reciprocation of the frame D can be accurately regulated to accord with the size or character of the rope which is being wound, and to cause a quick, slow, or medium action of the tension devices only one of the collars need be adjustable.
The shaft f is adapted to suitable bearings in a hanger f and is provided with a worm f which meshes with a worm-wheel g on a shaft g, to which is also secured a cam-disk g adapted to act upon a lug t on an arm '6, which is pivoted to a stud 2' upon the frame of the machine and has at the upper end a flanged pulley 1' which bears upon the belt a in its passage between the pulleys a a The spindle 7c of the pulley '6 is adapted to a segmental slot in the upper end of the arm i and can be secured in any position of adj ustment in said slot by means of its nut k so that the pulley '5 can primarily be caused to bear with any desired degree of force against the belt a.
When the machine commences to wind the rope upon the spool, the lug z" of the armi occupies a position on the lowest portion of the cam 9 as shown in Fig. 2, but as the operation of the machine continues said cam is turned in the direction of the arrow, Fig. 2,
so as to gradually move the arm z' inward and cause the pulley i to bear with constantlyincreasing force against the belt 2" and thus constantly and gradually increase the friction exerted upon the pulley a, thereby gradually augmenting the drag upon or retardation of the spool to accord with the gradually-hr creasing weight of thesame due to the increased diameter of its load of rope, the lug i finally reaching the highest portion of the cam g by the time the spool is fully wound. The shaft 9 also carries an arm m, as shown in Fig. 1, this aim beingadapted to act upon the underside of a shipper-rod m which controls the driving-belt of the machine. Normally this shipper-rod is retained in position to direct the belt to the fast pulley it upon the driving-shaft by reason of the engagement of a shoulderm of the rod with a guidebracket m on the frame. By the time the spool is fully wound, however, the arm on has acted upon the shipper-rod so as to lift the same sufiiciently to free its shoulder from engagement with said guide-bracket, thereby permitting movement of the shipper-rod under the action of a spring m4, so as to direct the driving-belt Onto the loose pulley 'n and thus stop the operation of the machine, the p vot-p n r o h h pper-rod e ng ap e to a slot 19 in the frame, so as to permit of this longitudinal movement of the rod. After the filled spool has been removed from the machine and a fresh spool inserted the shaft f is turned by means of a hand-wheel s, so as to continue the forward movement of the cam g until the lug e" of the arm 2' again rests upon the low portion of the cam, the tension of the belt a tending to move the arm '6 con stantly outward, so as to press said lug z" toward the face of the cam. The same movement of the cam 9* also carries the arm m so far forward as to permit the lowering of the shipper-rod m sufficiently to cause it to again engage with the guide-bracket 991* when said shipper-rod has been retracted so as to. again direct the driving-belt onto the fast pulley 2 this operation being effected by hand, but being impossible until the movement of the cam g by hand in the manner before set forth has first been effected. Hence it is impossible to start the machine until the tension devices are in normal starting position.
\Vhere the character of the rope produced by the machine is uniform, and the action of the belt-tightener i can consequently also be uniform, the cam 9 can, if desired, be driven in a manner different from that illustrated in Figs. 1, 2 and 3. For instance, the shaft B may have a worm c meshing with a wormwheel 12 on a shaft 12 which has a worm c for driving the wheel 9 011 the cam-shaft 9.
Having thus described my invention, I claim and desire to secure by Letters Patent- 1. The combination of the frictional re tarder for the winding-spool of a spinning or twisting machine, one of the elements of which frictional retarder is a belt passing round a pair of pulleys, an arm carrying a pulley acting upon said belt so as to increase the tension of the same when moved in one direction and decrease the tension when moved in the opposite direction, a cam for acting upon said arm, and means for operating said cam, substantially as specified.
2. The combination of the frictional retarder for the winding-spool of a spinning or twisting machine, a longitudinally-reciprocating frame, a tension device acting upon said frictional retarder, a cam for operating said tension device, and mechanism whereby the reciprocating movement of the frame is caused to impart rotating motion to said cam, substantially as specified.
3. The combination of the frictional retarder for the winding-spool of a spinning or twisting machine, a longitudinally-reciprocating'frame, a tension device acting upon said frictional retarder, a cam for operating said tension device, and mechanism whereby the reciprocating movement of the frame is caused to impart rotating motion to said cam, one of the elements of said mechanism being a bar with adjustable collar to be struck by an attachment of the reciprocating frame, so as to vary the extent of movement imparted to the bar by the frame, substantially as specified.
4;. The combination of the frictional retarder for the winding-spool of a spinning or twisting machine, a longitudinally-reciproeating frame, a tension device acting upon said frictional retarder, a cam for operating said tension device, a cam-shaft having a worlll-wheel, a worm engaging with said worm-wheel, and having a shaft with ratchet- Wheel, and a ratchet-bar engaging with said ratchet-wheel and operated by the reciprocating frame, substantially as specified.
5. The combination of the frictional retarder for the winding-spool of a spinning or twisting machine, a tension device acting upon said frictional retarder, a belt-shifter, and means for actuating said tension device and belt-shifter, the latter operating before the tension-operating device has completed its movement, substantially as specified.
6. The combination of the frictional retarder for the Winding-spool of a spinning or twisting machine, a longitudinally-reciproeating frame, a tension device acting on said frictional retarder, a belt-shipper, a shaft having a cam for operating the tension device, and an arm for tripping said belt-shipper, and means whereby the reciprocating frame is caused to impart rotating motion to said shaft, substantially as specified.
7. The combination of the frictional retarder for the winding-spool of a spinning or twisting machine, a tension device acting upon said frictional retarder, a cam for operating said tension device, means for automati cally actuating said cam, and provision whereby said cam can also be actuated by hand IIO ingthe shaft by hand to complete the movement and advance the trippenarm so as to permit of the readjustment and retention of the belt-shifter, substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
