SPECIFICATION forming part of Letters Patent 1Y0-(758,520, dated April 26, 1904. Application led December l, 1902. Serial No. 133,515. (No model.)

To all whom 7115 www concern:

Be it known that I, GEORGE A. FREDEN-- BURGH, a citizen of the United States, residing at the city of Pawtucket, in the county'of Providence and State of Rhode Island, have invented certain new and useful Improvements in Thread-Dressing Machines, of which the following is a specification.

My invention relates to a thread-dressing machine provided with brush-cylinders and ironers; and it consists of the novel construction and combination of the several parts, as hereinafter described, and specifically set forth in the claims.

Figure 1 is a view, partly in top plan and partly in central longitudinal section, of the left-hand portion of my improved threaddressing machine. Fig. 2 is a like view of the right-hand portion of said machine. Fig. 3 is a view of said machine as seen, partly in elevation and partly in section, on line X X of Fig. 1. Fig. 4 is a top plan view of the said machine on a smaller scale. Fig. 5 is a front elevation of one of the ironers. Fig. 6 is an end elevation of the same. Fig. 7 is a side elevation of the ball-bearing screw-plug. Fig. 8 is an end elevation of the same. Fig. 9-is a side elevation of the brush-cylinders and ironers and the mechanism for driving the same, respectively, together with the thread-guides directing the thread to said brush-cylinders and said ironers. Fig. 10 is a view in front elevation of two contiguous ironers and shows the direction of the movements of the threads in passing over the same.

Fig. 11 is a central longitudinal section of one of the brush-cylinders. Fig.- 12 is a central longitudinal section'o'f a modified form of an ironer.

Like characters indicate like parts.

In the drawings, 1 represents the brackets or supports ofv the machine secured by bolts 2 upon the frame of a machine and furnished with bearings or journals 3 4. In the journalbearings 3 3 the shaft l 5 is rotatably mounted, and semitubular caps 6 cover the said shaft and are secured to the bearings 3 3 Vtubular shaft 18, as shown in Fig. 1.

nal-bearing 3, and on the hub of said gear 13 u is keyed a driving-pulley 11. rounds the'shaft 5 and lies close to the inner face of the hub of the gear 13, and saidl collar is held in place upon the shaft 5 lby a setscrew 10. Another collar, 9, also surrounds the shaft 5 and lies close to the inner face of the right-hand journal-bearing 3, and said collar is' held in .place upon the shaft 5 by a set-screw 10a. Said collars 8 and 9 serve to prevent longitudinal movement of the shaft 5. At the end of the shaft 5 is also a drivingpulley 14, fastened thereon by a key 15 and is driven by a belt 16. A gear 17 is also fastened on the shaft 5 by said key 15. In the journal-bearings 4 4 are vmounted rotatably the tubular shafts 18 and 19, as seen in Figs. 1 and 2. A gear 20 is mounted on the tubular shaft 18 and lis fastened thereon by a key 21. The gear 20 meshes with the gear 17. A tubular cap 22, having a central aperture and screw-threaded on its inner surface, is secured upon the outer threaded end of the A stationary steam-pipe 23 passes through the central aperture of the cap 22 and extends into the tubular shaft 18. A semitubular cap 24 covers the tubular shaft 18 and is fastened by bolts 25 to thejournal-bearing '4.v A gear 26 is fastened by a key 27 upon the hub of an internal gear 43and said internal gear is loosely mounted upon a reduced portion of the hub of A collar 8 sur.

the journal-bearing 4. (See Fig. 1.) The gear 26 meshes with the gear 13. In the opposite journal-bearing 4, Fig. 2, is rotatably mounted the tubular shaft 19. A semitubular cap 28 covers the end of the shaft 19 and is fastened to the journal-bearing4 by screws 29. A tubular cap 30, whose head has a central aperture, is screwed upon the outer threaded end of the tubular shaft 19. A stationary steam-pipe 31 passes through the central aperture of the cap 31 and extends into the tubular shaft 19.

On the tubular shaft 18, at the inherscrewthreaded end thereof, is fastened, by means of a screw-threaded hub 32, the disk 33, having the flanges 34 and 35. A disk 36 is secured to the flange 35 of the disk 33 by the screws IOO arranged in a circle.

tubular hub 40 and a eircularly-arrangcd series of tubular screw-threaded bosses 41.

A tubular shaft 46 has screw-threaded ends one of which engages with the screw-threaded hub 40 of the disk 36, to which hub it is keyed, as shown at 47.

As seen in Fig. 2, the disk 48 has a screwthreaded hub 49, by which it is engaged with the screw-threaded end of the tubular shaft 19. The disk 48 has the anges 50 51. A disk 52 has a screw-threaded hub 53, which receives one of the screw-threaded ends of the tubular shaft 46 and is there fastened to said shaft by the key 42. A plug 37 fills the tubular shaft 46 at the end thereof. (Shown in Fig. 2). The disk 52 is secured by screws 54 to the ange 51 of the disk 48. The disk 52 has also a series of screw-threaded bosses 55, Tubular shafts 56 56 have their end portions screw-threaded to engage in the threaded bosses 41 55 of the disks 36 52, respectively. Nuts 58 59 are mounted on the threaded portions of said tubular shafts to impinge against said disks 36 52 in holding said tubular shafts iiXedly secured to the same in the manner shown in Fig. 1. The ironer 60 has its ends concentrically reduced to form hubs, as shown at 61, and these hubs 61 are screw-threaded on their interior surfaces and beveled inwardly to form a ballbearing channel, as seen in Figs. 1 and 2. A screw-plug 62 engages the screw-threads of the hub 61 and is beveled inwardly, so that between the hub 61 and screw-plug 62 is formed aV-shaped channel in which balls 63 are mounted. On the hub 61 is mounted and fastened by a screw 64 a gear 65, which engages with the teeth 45 of the wheel 43. On the inner end of each ironer 60 is a similar ball-bearing device, and on each tubular shaft 56 there are two ironers 60 of similar construction. Each of these ironers 60 at their Vinner ends has the semi-annular flanges 66, which together in abutment form an annular ange, as indicated in dotted lines in Figs. 1 and 2.

The tubular shafts 56 have a series of steam passages or openings 67 through them. The peripheral portion of the ironers 60 is formed into a series of integral cone-shaped sections the outer surfaces of which incline in the reverse direction from those of the next adjacent cylinder, and each of lthese sections has a V-shaped groove spirally arranged, the spiral grooves of one ironer being directed in a right-handed course, while the spiral grooves of the next ironer are directed in a left-handed course, as seen in Figs. 4 and 10. If desired, these grooves may be U-shaped.

In Fig. 9 I show a set of six contiguous ironers 60 at the upper part of my machine and having the construction and arrangement of parts and driving mechanism therefor as above described, while below said six ironers I shov.v a set of three ironers 6Q and three brush-cylinders 68 alternately arranged in a circle. The shells of these brush-cylinders 68 are constructed similar to the shells of the ironers above described, (see Fig. 11,) and the shells of said brush-cylinders 68 rotate around perforated tubular shafts 70, whose ends are ixedly secured to disks similar to the disks 36 52. Each of said brush-cylinders 68 is arranged to receive balls and screw-plugs similar to those used with the ironers, and on each brush-cylinder 68 and on each lower ironer 60 is keyed a gear 71, which engages the teeth of a large internal gear 69, that is rotatably mounted on the projecting hub of a bracket or support of the machine. On the hub of said internal gear is keyed agear, as indicated by dotted pitch circle 73 in Fig. 9. Said gear 73 meshes with the gear 75, that is loosely mounted on a rotatable shaft 74 of the bracket or support of the machine. On a tubular shaft mounted in the above-mentioned bracket is keyed a gear 72, and said gear 72 meshes with a gear indicated by dotted pitch circle 76, that is keyed upon the driving-shaft 74. The gear 75 has a projecting hub, and on the hub of said gear is keyed a pulley 77, which has a belt connection 79. At the end of the shaft 74 is also keyed a pulley which is driven by a belt connection 78, so that the driving mechanism for said brush-cylinders and their respective ironers is in all respects like that used with the upper set of ironers above described. The brush-cylinders 68 have brushes 80 on their peripheries. In Fig. 9 are also shown threadguides 81 82 83, suitably mounted. In Figs. 9 and 10 the thread is designated as a.

o In Fig. 12 I show a modified form of the ironer, in which the periphery is cylindrical instead of being formed with a succession of cone-shaped sections, as seen in Figs. 4 and 10.

Steam passes from a boiler through the pipe 31 into the tubular shaft 19, thence into the chamber 84, (which is formed between the disks 48 and 52,) and from the chamber 84 it passes through all the tubular shafts 56, thence into the chamber 57, thence into the tubular shaft 18, and thence through the steam-pipe 23 into the exhaust. While passing through the tubular shafts 56 it escapes through some of the openings or holes 67 into the ironers 60, respectively, and passes thence through others of the openings or holes 67 into the tubular shafts 56 again, thus heating the ironers 60. In like manner the brush-cylinders 68 and their respective ironers 60 are heated by steam.

The action of the gearing is as follows: rIhe pulley 14 being driven by the belt 16 turns the shaft 5 and with it the gear 17, said pulley and gear being keyed to the shaft, as shown n Fig. 1. The gear 17 turns the gear 20, which is keyed to the tubular shaft 18, and the tubular shaft 18 in turning rotates the disks 33 and 36 with it. As the tubular shaft 46 is secured and keyed at one end to the hub 47 of the disk 36 and at the opposite end to IOO IIO

thev hub 53 of the diskv 52 and as the tubular shaft 19 is secured and keyed to the hub 49 band or belt 12 causes the rotation of the gear 13, (to whose hub said pulley 11 is keyed, as shown at 85 in Fig. 1.) The gear 13 is mounted loosely on the shaft 5'. The gear 13 meshes with the gear 26, which is keyed at 27 to the hub 44 of the wheel 43. The wheel 43 has the circular series of internal gear-teeth 45, and these engage the gears 65, which are secured by the screws 64 tothe hubs 61 of the ironers 60. The gear 13 being of larger diameterthan the gear 26 causes the internal gear 43, which meshes with the gears 65, to revolve the ironers at a much` higher speed than that of the disks 36 and 52. The thread a comes up from the usual sizing-box (not shown) and is guided by the thread-guide 81 to the lower set of alternately-arranged brushes 8O and ironers 6() and thence passing through the .thread-guide 82 goes to the set of ironers 60 next above, where the thread is finally polished.

In the lower series of alternately-arranged brush-cylindersand ironers (see Fig. 9) the thread when wet with the sizing is first brushed so as to lay all its projecting fibers straight and then ironed and again brushed and then ironed, and so on, as the parts rapidly revolveV and being delivered from the ironers so as to pass straight over the brush-cylinders and from the brush-cylinders so as to pass diagonally over the ironersv in 'the spiral grooves thereof is thoroughly dressed and passes to the upper series of ironers, where it is polished. The thread then passes thorough the thread-guides 83 and is wound on the spools. By having the spiral grooves of one cylinder arranged in a direction opposite to that of the spiral grooves in the next cylinder, as shown in Fig. 10, the threads are drawn to a proper tension and caused to move in alternately-opposite diagonal directions. In this manner the thread is evenly polished all around.

Instead of using steam, as above described, it is obvious that gas may be used or a mixture of gas and air for heating the brushcylinders and ironers.

This invention is an improvement upon the thread-dressing machine shown and described in Letters Patent of the United States No. 7 02,7 86 issued to me June 17, 1902.
