To all whom it may concern:

Be it known that I, CHARLES E. LOMBARD, a citizen of the United States, residing at East Wilton, in the county of Franklin and State of Maine, have invented certain new and useful Improvements in Spinning and Twisting Machines, of which the following is a specification, reference being had to the accompanying drawings,

My invention relates to improvements in spinning and twisting machines.

One object of the invention is to provide an improved mechanism for actuating the fliers to build up the yarn upon the bobbins.

Another object of the invention is to provide a tension or brake device for the bobbin spindles. A

A further object of the invention is to improve and simplify theconstruction of machines or apparatus of this character and thereby render the same moredurable and efficient and less expensive.

With the above and'other objects in view, which will appear as the nature of the invention is better understood, the same consists of the novel features of construction and the combination and arrangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure l is a side elevation of my ininroved yarn spinningand twisting machine; Fig. 2 is a top plan view, parts being broken away and in section, of the spinning and twisting mechanism; Fig. 3 is a rear end elevation of the same; Fig. 4 is a detail longitudinal section through one of the twisters or fliers and the co-acting parts; Fig. 5 is a detail side elevation, on an enlarged scale, of portions of the builder mechanism; Fig. 6 is a detail vertical section taken on the plane indicated by the line 66 in Fig. 5; and Fig. 7 is a detail vertical section taken on the plane indicated by the line 77 in Fig. 5.

In the drawings 1 denotes the main frame on which the spinning and twisting mechanism is mounted and 2 denotes a supplemental frame (which may be made a part of the main frame) on which is mounted mechanism for feeding the yarn or roving. The frame or support 2 has arranged within it adjacent to its front or outer end a yarn feed drum 3 against the periphery of which two yarn spools or drums 4, 5 are adapted to bear and to be rotated by reason of their frictional contact with the drum 3. The upper supply spool 4 has at its ends pivots or trunnions 6 which bear against the upper edges of the inclined supporting arms 7 projecting from the opposite sides of the frame 2. The weight of the spool 4 thus holds itin contact with the feed drum 3. The lower yarn supply spool 5 has at its ends pivots 8 which are removably engaged with hook shaped bearings formed in the lower ends of hanger arms 9 which are carried by a transverse shaft 10 arranged for rocking or oscillatory movement in bearing notches formed in the upper end of the arms or supports 7. Upon one end of the rock shaft 10 is a depending crank arm 11 between the lower end of which and the frame 2 is a coil spring 12. The latter swings the arm 11 inwardly and hence actuates the hanger 9 to press the spool 5 against the feed drum 3.

The strands of yarn or roving a from the upper spool 4 pass through a suitable transverse guide 13 and between an upper set of

rolls

14, 15, 16; and they lead to the fliers of the upper set of bobbins as presently explained. The strands of yarn or roving b from the supply spool 5 pass through a transverse guide 17 and between a lower set of

rolls

18, 19, 20; and they pass to the fliers of the lower set of bobbins. There is no drawing action betweenthe

drums

3, 14, 15 and 16 and the

drums

18, 19 and 20. The

upper rolls

14, 18, of each of the two sets are supported upon the two lower rolls of each set, which lower rolls are geared together by providing an idler pinion 21 which meshes with pinions' 22 on the shafts of said lower rolls. On the shafts of the

rolls

16, 20, are gears 23, 24, both of which mesh with a gear 25 loosely mounted upon a stub shaft 011 the frame 2. The gear 24 also meshes with an idler gear 26 which in turn meshes with a gear 27 on the shaft of the feed drum 3. Carried by the gear 25 is a pulley 28 which is connected by a belt 29 to a cone pulley 3O loosely arranged on a stub shaft on the frame 2. The cone pulley 30 is connected by a crossed belt 31 to a cone pulley 32 loosely mounted on a stub shaft on the frame 2 and carrying a belt wheel or pulley 33.

Arranged upon the upper portion of the main frame 1 are transversely extending upright supports or

standards

34, 35, in which are arranged upper and lower sets or horizontal series of spindles 36 which carry upon their outer ends the usual bobbins 37. Coacting with each of the bobbins is a flier 38 able builder frame or member 67.

constructed preferably as shown in Fig. 4 and comprising a head 39 rotatably and slidably mounted upon the inner portion of the spindle 36 and provided at its rear end with a tubular extension or shaft 40 and upon its front end with oppositely disposed rods ll arranged for sliding movement in a grooved pulley 42 which latter is swiveled or mounted for rotation in the standard or upright 34. The outer ends of the rods 41 are connected and one of them carries a hook 4.3 to receive the yarn or roving.

The fliers of the upper set of bobbins are driven by belts fist passed around the pulleys L2 and an upper driving drum or roll at?) journaled in an extended front portion of the frame l. The fliers of the lower set of bobbins are similarly driven by belts L6 arranged between the pulleys 42 and a lower drum or roll l7 journaled in the lower front portion of the frame 1. The shafts of the drums 45, T7, are provided with pulleys etS which are connected by belts 49 to a double pulley 50 fixed upon a transverse shaft 51, which latter is connected by a train of speed gears 52 to a transverse shaft 58. On one end of the latter is a pinion 5 L which meshes with a driving gear 55 on a main drive shaft 60 to which latter power may be applied in any suitable manner.

On the shaft 60 is a pulley 61 which is connected by a belt 62 to the pulley or wheel 33, so that the feeding mechanism upon the frame 2 will be driven from the mechanism upon the frame 1.

The fliers 38 are reciprocated longitudinally of the bobbins for the purpose of building up the yarn thereon, by rack bars 63, which have their forward ends rotatably and non slidably connected to the fliers, preferably, by providing them with sleeves 64 which are arranged upon the tubular extensions or portions 40 of the flier heads and retained thereon by collars This con- .nection of the forward ends of the rack bars is sutiiciently loose to allow their rear ends to have a slight vertical movement. Said rear ends of the bars 63, on the upper edges of which are formed racks, project through a suitable opening in the rear support or upright 35 and also through openings in a transverse guide bar 66 arranged in a mov- The latter preferably mounted for swinging or oscillatory movement at the rear of the main frame 1 and as shown is of substantially U- shape consisting of two depending side plates or arms 68 fixed at their lower ends upon a transverse rock shaft 69 suitably journaled on the frame 1 and having their enlarged upper portions connect-ed by the guide 66 and a cross piece 67 The guide (36 holds the rack 63 in mesh with pinions 71 'on a transverse shaft 72 iournaled in bearings in the side plates 68 of the builder. On

one end of the shaft 72 is a worm gear 73 adapted to mesh with a worm 74 on one end of a shaft 45 journaled in suitable bearings on a retractable support 76 which is preferably in the form of a plate pivoted at its lower end at 77 on one of the arms or side plates (38 and adapted to have its upper end secured to the upper portion of the latter by a clamping screw 78 or an equivalent clamping or securing device. By pivoting the support or plate 76 it will be seen that the worm 74 which it carries may be moved out of mesh with the gear 73 so that the racks (33 may be drawn inwardly in resetting the builder mechanism as hereinafter explained. The shaft is prevented from moving in one direction, preferably, by fixing to it a ratchet wheel 79 which is engaged by a spring actuated pawl or dog 80 pivoted at 81 upon the plate or support 76; and said shaft is rotated in the other direc tion by the engagement of a gear 82 with a stationary rack 83 arranged upon the main frame and preferably upon the upright or standard The gear 82 is loose upon the upper portion of the shaft 75 but is connected to it for rotation in one direction by a. pawl and ratchet device consisting of a ratchet wheel 84 fixed on the shaft and adapted to be engaged by a spring actuated pawl or dog pivoted upon said gear. This pawl and ratchet coni'iection between the gear and the shaft allows the former to turn in one direction without rotating said shaft and hence without actuating the shaft 72 and the racks 63, while the last mentioned parts will be actuated when the gear 82 is rotated in the opposite direction.

The rock shaft or pivot (39 for the flier is actuated so as to rock or oscillate the latter by means of a heart shaped cam 86 arranged on the main drive shaft (30 and adapted to have its periphery engaged by an anti-friction roller 87 on a lever 88 suitably pivoted at 89 in the frame 1. The lever 88 has an arm 90 which is connected by a link 91 to a crank arm on the shaft (39.

For the purpose of varying the speed of the bobbin carrying spindles while the yarn is being wound upon different portions of the bobbins I provide a tension or friction brake device for said spindles. This device consists of a friction disk or wheel 93 arranged upon the projecting rear end of each of the spindles 3(5 and adapted to be engaged by a brake spring 94 arranged upon a slidable operating bar 95. The bar 95 is preferably arranged upon the rear face of the upright 35 between the upper and lower sets of spindles as more clearly shown in Fig. 3, and the springs or resilient brake shoes 9% project upwardly and downwardly from said bar so as to engage the disks 93. The pressure exerted by the springs SH against the disks is adapted to be regulated by set screws 96 arranged in studs or projections upon said bar and adapted to impinge against said springs as shown. One end of the bar 95 is connected to one arm of a bell crank 96 pivoted at its angle at 97 on the frame 1 and having its other arm connected by a link 98 to a crank arm 99 on the rock shaft (39.

The operation of the machine is as follows: The spools 4t, .5, containing the yarn or roving are properly supported as shown in Fig. 1 and the strands a b are passed through the guides and the rolls on the frame 2 and after being engaged with the hooks 43 of the fliers are attached to the bobbins. Power is applied to the main drive shaft 60 and the various parts of the machine receive their motion from said shaft through the gearing above described. The supply spools or drums 4, 5, being pressed, the former by gravity and the latter by the spring 12, against the positively driven drum 8 are rotated by the latter and the strands of yarn a b are fed to the guides and the upper and lower sets of rolls as will be readily understood. Owing to the provision of the speed gearing 52 between the main shaft 60 and the shaft 51 from which the rolls 45, &7 are driven, the fliers will-be driven at a higher rate of speed than the bobbins and hence the strands of yarn will be thoroughly twisted before being wound upon the bobbins. The heart shaped cam 86 will oscillate the lever 88 and the movement of the latter will be imparted through the intermediate connections to the rock shaft 69 to which the builder frame or member 67 is connected, and hence the latter will be oscillated. This oscillation of the builder causes the rack bars 63 and hence the fliersto be reciprocated; and owing to the engagement of the gear 82 with the stationary rack 88, said gear will be oscillated and when it rotates in one direction the worm shaft 75 will turn with it and will actuate the shaft 72 carrying the pinions 71, consequently said racks will be moved forward a little more than the length of the rocking movement of the builder, and the fliers willbe gradually moved longitudinally of the bobbins so that the yarn will be wound evenly upon the bobbins. When the gear 82 rotates in the opposite direction it will turn independent of the worm shaft 75, which latter will be held against rotation by the pawl 80 and the ratchet 7 9. The movement of the rock shaft 69 is also imparted through the

parts

99, 98 and 96 to the bar 95 so that the latter will be reciprocated and will vary the tension of the brake springs 94 upon the brake disks or wheels 93 on the bobbin carrying spindles. The operation of these parts is so regulated that when the yarn is being wound upon the small 'or tapered part of the bobbins the bar 95 moves outwardly to relieve the tension of the brake springs upon. the brake disks or wheels and when the yarn is being wound upon the larger portions of the bobbins the friction is increased by the movement of said bar in the opposite direction. After the bobbins are full, the screw or fastener 78 is operated to release the plate or support 7 6 which may then be swung to disengage the worm 74 from the gear 7 8 so that the racks 63 may be drawn rearwardly and reset.

It will be understood that any suitable mechanism other than the one illustrated and described may be used in connection with my improved builder mechanism for feeding the yarns thereto and that the bobbins may be disposed either vertically or horizontally according to the character of the feeding device or mechanism.
