MOSES SPENCER, OF SAYLESVILLE, RHODE ISLAND, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO HOPEDALE MANUFACTURING COMPANY, OF MILFORD, MASSACHUSETTS,

A CORPORATION OF MASSACHUSETTS.

To all whom it may concern Be it known that I, Mosns SPENCER, a citizen of the United States, residing at Saylesville, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Spinning Frames; 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.

The present invention relates to an improvement in spinning frames, and more particularly the invention relates to an 1mprovement in bunch-building mechanisms.

The object of the invention is to improve and simplify the construction of bunchbuilding mechanisms in order that these mechanisms and devices may perform their 20. respective functions more efiiciently. To the accomplishment of this object and such other objects as shall hereinafter appear, the invention consists in the improved spinning frame described and particularly pointed out in the following specification.

In the accompanying drawings illustrating the preferred form in which it is contemplated embodying the invention, Figure 1 is a front elevation of aportion of a spinning frame showing the application thereto of the bunch-building mechanism; Fig. 2 is an enlarged view of the butt end of a bobbin showing the preliminary bunch as spun thereon by the bunch-building mechanlsm;

5 Fig. 3 is a side elevation on an enlarged scale of a part of the bunch-building mechanism and adjacent parts of the spinning frame; Fig. 4 is a plan of the parts shown in. Fig. 3; and Fig. 5 is'a detail of the cam gear showing it in a different position.

In its general features of construction, the spinning frame to which the improved bunchbuilding mechanism is applied, may be of any usual or preferred form and may be used for the spinning of woolen or cotton yarns. The spinning frame illustrated in the drawings comprises a spindle rail 9 secured to the frame 10 of the machine. Mounted on the spindle rail 9 are the spindles 11 which carry the bobbins 12, upon which the yarn 13 is spun. The laying of successive layers of yarn upon the bobbins is ef-- fected by the up and down traverse of the on rolls 01' wheels 22journa1ed in a bracket 23 fastened to the frame of the machine.

At the beginning of the spinning operation the carriage 20 makes its regular reciprocatory motion at the limit of its rightward movement, as shown in Fig. 1, thereby holding the lifter rail 14 raised in order that the butt of the bobbins may be spun first. Throughout the spinning operation the carriage progressively approaches the limit of its leftward movement, thereby permitting the lifter rail and bobbins to progressively descend. The movements of the carriage 20 to the right, as viewed'in Fig. 1, in order to raise the lifter rail, are imparted by a heartshaped cam 25 mounted on the end of a rotating shaft 26. The cam 25 engages a cam roll 27 carried .by an oscillatory arm 28 pivoted at 29 on a block 24'adjustably secured on the machine frame; The side 30 of the lower end of the arm 28 engages a roll 32 pivoted on a block 33 adjustable vertically on a lever 34 fulcrumed at 35 on a bracket 36. The upper end 38 of the lever 34 is guided in its oscillatory movements by an arc-shaped plate or guide 39. The lever 34 carries an internally-threaded nut 40 which receives a worm 41 formed on a shaft 42 journaled in the machine frame. The headed end 43 of the worm 41 loosely engages a block 44 fixed on the carrige 20.

The oscillatory movements of the lever 34 caused by the rotation of the heart-shaped cam, imparts a reciprocatorymotion to the shaft 42 and the carriage 20, the connections between the lever 34 and the nut 40 being such, as to permit the necessary relative motion between the two. The carriage 20 is connected with the, left-hand lifter rod 15 by means of a.chain 46, the lower end of which is fastened to a collar 47 adjustably secured to the lower end of the lifter rod. The chain 46 passes over an idler 48 pivoted on the bracket 23. The downward traverse therewith. The gear 50 is driven by; a gear 51 which in turn is driven from a suitable source of power.

7 The building of the preliminary bunch 5 5' on the butt end of the bobbins is eiiected by holding the carriage 20 substantially station ary at the limit of its rightward movement, for a predetermined length of time at the beginning of the spinning operation. This is accomplished by the bunch-building mechanism which comprises a lever 55 pivoted at 56 and having a hooked end which is adapted at the proper time to engage a stop lug58 secured to the carriage 20. The engagement of the hooked lever-55 with the stop lug 58 prevents the leftward movement of the carriage, thereby permitting the bunch to be built on the butt end of the bobbins. It will.

be understood that the engagement of the book 55 with the stop lug 58 does not absolutely prevent all movement of the carriage 20, but that the latter will have a slight movement as the tip of the heart-shaped cam 25 passes the cam roll 27. This slight movement of the carriage is suflicient to impart a small vertical traverse to the lifter rail,

- and consequently the preliminary winding or bunch will not be built up on one point, but will be distributed over a short length of the butt, as shown in Fig. 2.

"the spinning frame. During the regular The hook is lowered into engagement with the stop lug 58, at the beginning of the spinning operation, b the clockwise oscillation of a bellcrank ever 59 pivoted at 60 on the machine frame. The lever 59 is connected with the hook 55 by a s ring 61, so that if the bellcrank is actuate to lift the hook 55 while the carriage is attempting to move toward the left, a straining of the parts will not ensue. The bellcrank lever 59 is connected by means of a link 62 with a lever 63, which carries a cam roll 64 arranged to travel in a cam path 65 grooved in the web of a cam which is formed as a mutilated or interrupted gear 67 pivoted on a stud 68 secured to a bracket 69 fastened to the end of spinning operation, the cam gear or cam 67 is maintained in the position shown in Fig. 4, which may be called its normal or inoperative position, and the hook 55 is thereby held raised; but during the building of the preliminary bunch the cam gear 67 is in its operative position as shown in Fig. 5, with its cam groove in such position that the link 62 is moved to the right (as viewed inFig. l)

memos to permit the hook 55 to lowered into the path of the stop lug 58. The cam gear 67 1s turned into thG'POSItlOII of Fig. 4 by a pinion 71 loosely mounted on the lower end of a vertically disposed shaft 72, which rotates constantly in the direction indicated by the arrow in Fig. 4 and is driven by a constantly rotating worm 73. The driving connection between the shaft 72 and the pinion 71 consists of a collar 74 loosely mounted on the shaft 7 2 and in key and key-way connection therewith. lhe lower end of the collar 74 is provided with ratchet teeth which are adapted to mesh with corresponding teeth on the pinion. When the cam gear 67 has been turned into the position of Fig. 4, it is held therein by the engagement of a wedgeshaped stop lug 76 secured to the cam gear,

with a stop lever 77 pivoted at 78 on an upward extension of the stud 68. A contraction spring 79 tends to hold the stop lever downward in the position shown in Fig. 3, and the collar 7 4 in mesh with the pinion 71.

At the beginning ofthe spinning operation when the preliminary bunch is to be built, the collar 74 is disconnected from the pinion 71 and the stop lever is raised and disengaged from the stop lug 76. Thereupon a spring 81, fastened at one end to the bracket is wrapped around and secured to the hub of the cam gear 67, acts to turn the cam gear into its operativeposition, as shown in Fig. 5. The amount of rotation of the cam gear, which is determined by the length of time" the hook 55. is to engage the stop 58, which in turn is determined by the amount of yarn necessary to constitute the preliminary bunch, is limited by an adjustable stop 83 which, as the cam gear turns, is brought up against the cam roll '64.v The collar 74 is disengaged from the pinion 71 and the stop lever 77 is raised by means of a lever 84 ivoted at 85 on astud 86 rising from the gages a vertical slot 88 in the free end of' the stop lever 77. This slot 88 permits the stop lever to rise without disengaging the collar 74 from the pinion 71, when the gear 67 is being turned into ino rative position and the wedge-ska ed stop ug 76 passes under the stop lever 7. The outer end "of the lever-84 is articulated by means of a link 90 with a hand lever 91 pivoted at 92 on the machine frame. Thelever 91 is manipulated by the operator, in order to disconnect the collar 74 from the pinion 71 and to raise the stop lever 77 by .means of a handle 93. The handle 93 is integral with the arm 94 of the hand lever 91. This arm 94 is curved at 95 tofit a groove 96in the hub otthe gear 50; the

69 and at the other end to a strap 82 which 9 gear is thus prevented from axial movement with the shaft 42 during the regular spinning operation.

The building of the preliminary bunch on the butt end of the'bobbins is necessarily performed at the beginning of the spinning operation by reason of the construction and arrangement of the parts of the spinning frame. The progressive movements of the carriage toward the left (as viewed in Fig. 1) as the spinning proceeds, leaves the carniage substantially at the limit of its leftward movement at the completion of the spinning operation. Before the spinning of the next set of bobbins can be commenced, it will be necessary for the operator to return the carriage to its initial position, that is, to the limit of its rightward movement. This he does by turning the hand Wheel 97 fixed on the outer end of the shaft 42. Before the shaft 42 can be rotated, however, the gear 50 musbe disconnected from the gear 51, and before this can be done, the operator must disengage the hand lever 91 from the groove in the gear 50. In doing so, he oscillates the lever 84, thereby disconnecting the collar 74 from the pinion 71 and raising the stop lever 77. Thereupon the spring 81 acts to turn the cam gear 67 into operative position, by which movement the bellcrank 59 is oscillated in a clockwise direction and the hook'55 is lowered into the path of the stop lug 58. It is thus seen that the preliminary bunch building is necessarily incident to the spinning operation.

- The amount of yarn constituting the preliminary bunch is dependent upon the length of time the hook is in engagement with the stop lug 58, and this in turn is dependent upon the rate of rotation of the shaft 72 and the adjustment of the stop 83. Before the operator restarts the spinning frame in operation, he must slide the gear 50 into mesh with the gear 51. Having done so he rev leases the handle 93, and thereupon the spring 79 slides the collar 74 into mesh with the pinion and depresses the stop lever 77 into operative position. Incidentally, the curved part 95 of the arm 94 is inserted in the groove 96. The rotation of the pinion 71 now turns the cam gear 67 from the position of Fig. 5 to that of Fig. 4. It will be seen that the nearer the stop 83 is set'to the active part 98 of the cam path 65, the shorter time the hook 55 will be in engagement with the stop 58.

The stopping devices for automatically stopping the spinning frame upon the com pletion of the spinning operation, comprise a bellcrank lever 100, by the oscillation of which in a clockwise direction the shipper 101 is actuated to shift the belt 102 from the fast pulley 103 to the loose pulley 104-. The bellcrank lever 100 is oscillated by a lever 106 piv ted on an upright 107 fixe on the biock end of the rod terminates below a horizontally disposed shipper rod 114, the outer end of which is loosely received in a slot 115in the bracket 113. During the spinning operation the outer end of tlie shipper rod is depressed and a notch 116 therein engages the lower end of the slot 115. But when the bellcrank 100 is oscillated at the completion of the spinning operation, the rod 111 is raised and brought up against rod; the notch 116 of the latter is thereby disconnected from the bracket 113, and there upon a spring 118 acts to draw the shipper rod 114 to the right (as viewed in Fig. 1). The movement of the shipper rod to the right, actuates the shipper 101 with which the rod 114 is connected by the arm 119, the bar 120 and the arm 121. The actuation of the shlpper 101, asbefore described, shifts the belt 102 from the loose pulley 104 and stops the machine.
