CHARLES MILLS AND LOREN W. PENNEY, OF NEWTON, MASSACHUSETTS, ASSIGNORS,

BY MESNE ASSIGNMENTS, TO SACO-PETTEE COMPANY, OF NEWTON, MASSACHU- SETTS, A CORPORATION OF MASSACHUSETTS.

LAP-WINDER.

To all whom it may concern:

Be it known that we, CHARLES Mums and LonnN W. PENNEY, of Newton, in the county of Middlesex and State of Massachusetts, both citizens of the United States, have invented new and useful Improvements in La1)-lVi11cleI-s, of which the following is a specification.

Our invention relates to that class of lap Winders in which the slivers are combined to form the lap which is wound upon a core of wood or the like under the pressure of fluted rolls which not only rotate the core with the lap wound. upon it by frictional contact therewith, but also compress the lap so that it is tightly wound.

Our invention comprises mechanism for causing a radial movement of the core and top roll as the core is wound as well as a positive and relative movement of those parts.

It also comprises certain details of construction relating to the stop motions of which there are two, one stopping the machine when a given quantity of sliver has been wound on the core, and the other auto matic upon the breaking of a sliver.

It also comprises certain means for sup porting certain of the gears and allowing their axes to change relation as the winding progresses.

It also relates to certain details of construction to be referred to below.

Our invention will be understood by reference to the drawings in which the best embodiment of our invention now known to us is shown.

Figure 1 is a plan of a machine embodying our invention. Fig. 2 is an elevation showing the right side of the head of the machine. Fig. 3 is an elevation showing the left side of the head of the machine. Fig. 4: is a front view. Fig. 5 is'a section on line 5 5 of Fig. 2, the gear casings being removed. Fig. 5 is a sectional detail. Fig. 6 is a section on line 6-6 of Fig. 4:. Fig. 7 is an enlarged detail of the gear covers. Fig. 8 is a section on line 1010 of Fig. 7. Fig. 9 is a sectional elevation of the drop shaft and Fig. 10 is a modification thereof.

The machine as a whole comprises a head which carries power distributing elements and the winding elements and tables on which the slivers are drawn so as to be fed Specification of Letters Patent. Patented June 11, 1912,

Application filed July 19, 1909.

Serial No. 508,323.

to (tlhe tube or core on which it is to be car r1e We shall first describe the head. In a frame comprising sides A, and girths a are mounted the various shafts, studs and bearings carrying the various driving parts. In this frame A is mounted the power shaft 1 carrying at one end fast and loose pulleys 2 and 3. A belt shipper 4: of ordinary construction mounted on the rod 170 is provided to be used in connection with these pulleys,

it being operated in a way below described. Power is applied to the machine through a belt running on the fast pulley 2. Upon the further end of this shaft 1 is mounted a gear 5 which meshes with a large gear 6 mounted on one end of the shaft 7. This shaft which we have called a drop shaft is part of the stop motion and as such will be described later. For the present it is only necessary to say that at one end it is mounted in a bearing 8 supported from one of the sides of the frame and at the other end in a bearing 9 in the lever 10, and that when in its normal operative position the gear 88 at its farther end meshes with gear 89.

The shaft 7 carries a pinion 11, which meshes with gear 12 mounted on the shaft 13 carrying a fluted roll 14. An idler gear 15 mounted on stud 16 meshes with a gear 17 on the shaft 18 which shaft also carries the fluted roll 19. The shafts 13 and 18 are both mounted in hearings on each side of the frame and the idler is used to give them motion in the same direction. The rolls let and 19 serve as a bed for the core and lap as it is wound thereon. The third fluted roll which we call the top roll is marked 20 and it is mounted on a shaft 21 which is supported at one end in bearings 22 in a slide 221 which slides in ways 23 in the frame (see Fig. 2) and at the other end in bearings 26 in the slide 261 which slides in ways 27 in the frame, which ways are similar to the ways 23 above referred to. An extension of the shaft 21 lies in bearings 24 and 25 (see Fig. 8) and between these hearings is supported the gear 28. This gear 28 meshes with an idler 29 in mesh with the gear 17 this giving to the top roll 20 rotation in the same direction as the other grooved rolls. These grooved rolls are pres sure rolls to insure the proper winding of the laps upon the core 30. Our improveme-nt so far as it relates to this part of the machine consists in the peculiar manner in which one of the fluted rolls, say roll 19, is connected with top roll 20 so that power will always be transmitted to it as the lap increases in size and so lifts it and at the same time the transmitting gears will be protected from lint and yet be easily removable in case of necessity. For this purpose we have made the casing whichcovers the gears in two parts pivotally connected sothat as the rolls 19 and 20 separate the casing will conform to the new positions of the rolls, each part being made in two sections in order that the structure may be easily taken off the machine. This construction will be understood by reference'es pecially to Figs. 7 and 8. The inner section of the lower part of the casing is numbered 31 and it'has two bearings, the lower one beingfor'the shaft 18 and the upper one for the stud or axle 32 of the idler 29. The other section 33 of the lower part of the casing also has two bearings, one for shaft 18 and the other for axle 32, a bolt 34 and washer 35 holding this part of the casing in place on the shaft 18 and the gear 17 and section 31 carryingthe bearing 36'agai'nst the frame A. The other end of the shaft 18 may be held in its hearing by a suitable head or otherwise as described below. The upper part of the casing'is also made in two sections, "an inner'section 37 with a wide bearing 38 for the axle 32 and a wide bearing 39 for the shaft 21. It also has a flange 40 which engages the flange 41 on the outer section 42 of this part of the cover. This outer section has a wide bearing 43 for the shaft 21 and a wide bearing 44 for the axle 32. It is attached to the shaft 21 by a washer 45 and bolt 46 and the four overlapping parts of the-casing are attached to the stud by washers 47 and 48 and bolts 49, 50. These parts of the casing overlap considerably as shown in Fig. 7 so that they may assume either the position shown in Fig. 3 or that in Fig. 7 as occasion'may require. At all times, however, they protect the gears from lint and, what is fully as important, they serve as an easy way of holding the gears in place and at the same time allowing them to be easily removed, for by removing the'bolts 34, 46 and 49 and their washers the outer sections of the casing may be removedand the gears as well.

It is stated above that the top roll 20 is mounted on the shaft 21 supported in bearings'w-hich slide in ways 23 and 27 in the two-side frames of the machine. This separation of the top roll from the lower fluted rolls is necessary in order'to provide room for'the increasingsize of the work, by which we mean the core 30with the lap -wound on it. "It is necessary also that the core 30 shallr'est o'nthe lower fluted rolls 14 and 19 that is, the upper roll will rise approximately the full diameter of the lap roll while the center of the lap roll rises approximately half that distance. The core 30 lies between disks 51 and 52 which serve as guides to'the lap, consequently should move regularly as the lap increases in size. Each disk carries a stud 53 and 54 mounted in bearings 55 and 56. Each of the slides 221 and 261 which carrythe bearings 22 and 26 extends downward to a point near the bottom of the machine and carries at its lower end a rack bar 57, 58. Each slide 221, 261, is slotted as at 59 and 60 to provide an opening through which pass the studs 53 and 54, each stud being surrounded by a sleeve 55, 56, lying in slots 59 and 60 to center the studs and reduce friction. The end of each stud is supported in a casing 61, 62, which slides vertically inways 63, 64, and which carries at'its lower end a rackbar 65 and 66. Thus the top roll and the carriages which give it axial support have a vertical movement as well as the disks and their supporting carriages, allowing the vertical movement of the disk studs which pass through them. These disks are adjustable according to the desired width of the lap. The lap is always slightly wider than the core is long and the position of these disks is adjusted accordingly to give a slight clearance between them and the ends of the empty core when it is put in place. Thereafter the disks serve to guide the material as it winds on the core and also to shield it from the moving parts oft-he machine in proximity to it.

For purposes of adjustment the bearing in each carriage 63, 64, is threaded at its outer end, and screws 67 and 68 fitting into the bearing serve to adjust the position of the disks according to the length of the core and the width of the lap to be wound thereon. lVe prefer that each screw shall be pointed at its inner end to set into a corresponding cavity in the end of its stud 53, 54, and so reduce friction. The screw 67 has a square head so that it may be adjusted by a wrench, while the screw 68 at the other side of the machine is provided with a hand-wheel 69 preferably detachably attached thereto by which the position of-the screw and disk shall be adjusted in or out as occasion may require.

In practice it is usual to set the screw 67 in such position as to maintain the disk 51 in fixed i'elation'to the middle line of the machine and in removing a finished lap to turn the hand wheel 69 so as to withdraw the disk 52 from contact with the lap so thatupon liftin gthe top roll the-finished lap may be taken out from between the rolls 14, 19 and 20. After placing an empty core in the machine the hand-wheel 69 is turned in the opposite direction as far as may be desired leaving a slight clearance between the ends of the core and the disks.

The racks 57 and 58 connected to the top roll and the racks 65 and 66 connected to the carriages 61 and 62 cooperate to maintain the relations of the top roll and the disks and core in the following manner :-70 is a shaft one end of which is mounted in a side frame while the other end 75 is reduced in diameter and passes through a bushing 70 in the other side frame. This shaft carries two pinions 71 and 72 located between the side frames and smaller pinions 73 and 74 are cut in the shaft by the side of the pinions 71 and 72 (see Fig. 5). The diameter of the larger pinions 71 and 72 to the smaller pinions 73 and 74 is approximately as 2 to 1, and their teeth are of such number that the racks 65 and 66, which engage the pin ions 73 and 74 are moved approximately half as fast as the racks 57 and 58 which engage pinions 71 and 72. 1V hen therefore the roll 20, has been raised sufficiently high and the finished lap has been removed and a new core put in its place, the roll 20 is allowed to fall until it rests on the core 30, its weight also causing the disks 51 and 52 to come into proper winding position, the weight of the roll 20 acting for this purpose through the racks 57 and 58, their pinions 71 and 72, the pinions 73 and 74 and the racks 65 and 66. As the lap winding on the core 30 increases its diameter, the upper roll 20, disks 51 and 52 and core rise together in like manner.

An important feature of this latter construction is the utilizing of the one part with pinions 71 and 72 and 7 3 and 74 of different diameters to operate the two sets of rack bars simultaneously but at different rates of speed, thus reducing the mechanism, making the machine more compact, easier to construct and take apart and allowing the parts moving vertically to slide in proper ways without taking undue room, the racks in fact running side by side in the said ways.

In order to lift the top roll to any given position or hold it when unsupported by the core 30 means are provided as follows The shaft 7 O carries upon its reduced portion 7 5 a brake wheel 81 having a hub 81 extending on both sides of it, forming a sleeve upon one end of which is keyed a gear 76 in mesh with a gear 77 on the shaft 78 and on the outer end of said hub81 is keyed a hand wheel 87, the whole being held in place by a washer and nut. The shaft 78 also carries a gear 79 in mesh with the gear 80 on shaft 70. A brake lever 82 is caused to rest against the brake wheel 81 by the weight 83. This lever is pivoted at 84 to a projection 85 from the side of the frame and carries a treadle 86 at its front end so that the brake may be controlled at will. The weight 83 is preferably adjustable on the lever. To lift the roll 20 the brake wheel 81 is released and at the same time the hand-wheel 87 is turned in the proper direction to lift the top roll 20 and disks 51 and 52 through the instrumentality of the gears 76, 77, 79 and 80, pinions 71, 72, 73 and 74, and rack bars 57, 58 and 65 and 66. In addition to the pinion 11 the drop shaft 7 carries a gear 88 which engages a gear 89 on shaft 90 as referred to above. This shaft 90 is one of four shafts 90', 91, 92 and 93, the bearings for which lie in ways 94 in both side frames of the machine and carry calendar rolls 95, 96, 97 and 98, and gears 99, 100, 101, and 102, which gears are in mesh so that the four rolls deriving power from the shaft 90 rotate to feed the sliver which is introduced between them, the sliver being fed toward the head from the rear of the machine between the two top rolls 97 and 98, then back between 96 and 97, then forward again between 95 and 96 and under the tension roll 103 to the core 30. machines of this class.

A casing 104 sets over the gears 6, 99, 100, 101, 102, to protect them from lint and dust. It is provided with openings to engage supporting pins 105, 105 so that it may be liftedoff the machine when necessary to expose the gears for any purpose. The pins 105 project from a bracket 105 bolted to the frame and the pin 105 from a bracket 105 on the top of the frame. The pins 105 are preferably headed as shown. The gear 88 also serves to control the stop mechanism by which the machine is stopped when a given amount of lap has been wound. For this purpose the shaft 90 carries a worm 106 on its outer end which engages a gear 107 on the shaft 108 supported in bearings 109 on the side of the frame. At its forward end the shaft carries a pinion 110 which meshes with gear 111 on a stud 112 carried by the bracket 113. The gear 111 carries a pin 114 and on the stud 112 is a freely turning lug 114. The timing of these parts is such that the gear 111 rotates once while a given length of lap is wound on the core and then stops the machine in the following manner :Thelever 10 pivoted at 115 near the rear of the head extends forward terminating in a handle 116. 117 is a slotted arm pivoted at 118 on the front of the machine and having a shoulder 119' This construction is common in 10 and allows the lever to drop. This stops the machine for the reason that'one end of the drop shaft 7 is carried by the lever 10 and when the lever 10 drops it carries that end of the shaft 7 with it and disengages the gear 88 from the gear 89 and so disconnects the feed rolls from the power shaft. To make this possible the drop shaft 7 carries ateach end a bearing 8 and 9 of peculiar shape such as will allow it to rock vertically. As shown, both in Figs. 9 and 10, these bearings are in the form of sleeves on the shaft and are approximately egg-shaped. A set screw 120 holds each bearing from endwise movement in its support. It will be noted that but a slight drop is necessary to allow the disengagement of the gears 88 and 89 so that the end of the drop shaft 7 farthest from the lever 10 swings but slightly and the gears 6 and pinion 11 are not moved suflicien-tlyto cause their teeth to jam in the teeth of thegears in whichthey mesh. In some respects we prefer the construction shown in Fig. 10 in which the gear6 and pinion 11 are located on opposite sides of the bearing 8 which forms the fulcrum so that as the gear 6 is in this case nearer the fulcrum it has less motion.

The gear 89 engages an intermediate gear 121 mounted on a stud on the outside of the frame which gear meshes with gear 122 on the shaft 123. This shaft runs across the machine and is supported at each end in the frame. It carries at each end a bevel gear 122 each of which meshes with a bevel gear 126 on a shaft 127 running rearward over the table128on which it is supported. It will be seen that this mechanism is duplicated, one set being on one side of the table and the other on the other side thereof. Each shaft 127 forms the lower one of a pair of rolls, the upper roll 129 having a gear 130 which meshes with a gear 131 on shaft 127. By these means said pairs of calendar rolls are given a continuous movement.

The cans containing the sliver are located underneath the table 128 and each sliver is led up through an opening 132 in a support 125 bolted to the edge of the table and over a spoon lever or spoon as we shall call it, 133, from which it passes directly between the rolls 127 and 129. There is one opening 132 and one-spoon lever 133 for each sliver and the sliver in leaving the rolls passes around a pin 134 and from it directly between the calendar rolls 97 and 98, etc., as above described, to the core 30. In the 'machine shown provision is made for 42 slivers, 21 on each side of the machine.

To operate our machine,'the cans being in place and the slivers therefrom being carried up each through its own opening 132 over the spoon 133, bet-ween the rolls 127 and 129 and around its own pin 134, are passed bet-ween the calender rolls 97 and 98, then between the calender rolls 97 and 96, then between the calender rolls 96 and 95, and under the roll 103 to the core 30. Thefiuted roll 20 has been previously lifted by releasing the brake 82 and using the hand-wheel 87 to allow the core 30 to be properly fed with the ends of the slivers and the disks 51 and 52 have been adjusted according to the desired width of the finished lap, by using the hand-wheel 69. The ends having been fed to the core, the fluted roll 20 is allowed to drop onto the core and the machine is started. As the diameter of the lap increases it lifts the fluted roll 20 which lifts the disks 51, 52 by means of the racks 57 58, pinions 71 72, pinions 73 74 and racks 65, 66 until such time as the pin 114 has engaged the lug 114 and has forced it against the arm 117 so that it releases the lever 116 and allows it to fall carrying with it the drop shaft which in falling disengages the gear 88 from the gear 89 and so stops the feed. The hand-wheel 87 being then turned to lift roll 20 and the hand-wheel 69 being turned to release the lap the lap is removed and a new core 30 put in place and the operation repeated. During this latter operation the rotation of the rolls 14, 19, and 20 may, if desired, be stopped by operating the belt shipper 4.

This machine has proved its utility in these respects in which it differs from other machines already on the market owing to its simplicity of parts and the reduction of the parts necessary to its operation, and the ease with which those parts may be reached in case of accident. We prefer to make the slides 22,1 and 261 in sections, separable when they carry the bearing for the axle of the top roll. This will be understood from Figs..2 and 6 where the construction of one of the slides is shown in dotted lines. The slide 221 is constructed similarly in allrespects. The upper sections are marked 221 261 and are bolted to the lower sections by bolts 221, 261 a rod or brace 221 holding the upper sections together as shown. The great practical advantage of this improve ment lies in the fact that if it becomes necessary to remove the top roll, it is only necessary to remove the bolts 221 261 and lift off the upper sections, thus exposing the axle of the top roll so that it may be lifted out of the machine. Vere such a construction not adopted the weight of the top roll, slides and connected parts would require the use of a'tackle to move them.

One material advantage of this machine lies in the fact that it is virtually constructe ed in two parts the head which contains the winding mechanism and the table. This enables the machine to be shipped in two or more parts and easily set upin the mill. Moreover the two sides of the table being duplicates the angle at which they are set to 1.
