T0 ft// whom, t 711,/1/ 1/ concern:

Be it known that we, FRANK OHATFIELD and JAMES S'rRUTnERs, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Attachments for Fleecing or Napping Machines, of which the following is a specification.

Our invention relates to devices adapted for use in connection with a machine for l'leecing or napping a tubular fabric, such as is used in the manufacture of fleecelined garments. Y

The object of our invention is to provide means for changing the bend or fold in the fabric at the edges to avoid over napping or fleecing at that point as the material passes through -the machine. A

The invention consists generally in a mechanism or device for moving the fabric laterally to present a new surface at the point where the bend or fold is made at the edges of the flattened tube.

In the accompanying drawings, forming part of this specification, Figurel is a sectional view of a portion of a napping-machine with our invention applied thereto. Fig. 2 is a front view of the same. Fig. 3 is a plan view showing a board or plate with the shifting devices'mounted therein. Fig. 4 is a similar view of a modification adapted for use particularlyT when the invention is employed independently of the napping-mm chine. Fig-5 is a sectional view on the line :E no of Fig. 4. Fig. 6 is a sectional view on the line y y of Fig. 3. Fig. 7 is a detail view of the modified means of mounting the shifting devices in the supporting board or plate. Fig. 8 is a sectional view on the line 2 2 of Fig. 7.

In the drawings, 2 represents the frame of a napping or fleecing machine provided with shafts 3, 4, 5, and 6 and with rolls 7, S, 9, and 10, around which the fabric passes to the napping-wheels 11. These parts all correspond substantially to the shafts, rolls, and napping-wheels of a machine of this type in general use and need no detailed description herein.

We have found in the operation of this machine that the edges of the fabric have a tendency to sag as they pass over the napping-wheels, resulting in an overnapping of the fabric at the point where the bend or fold is made. To obviate this objection in the use of a machine of this type, we provide a plate 12, having, preferably, rounded corners on one side and gradually increasing in thickness from that side toward'the other.

Openings 13 are provided in the plate 12,

wherein brackets 14 are secured and provided with studs 15 and 16, projecting into the said openings and having oppositelyturned ends upon which toothedidle wheels 16 and 17 are journaled. These wheels, as clearly shown in Fig. 6, are arranged in pairs, one of them at each end of the board lying in a plane substantially parallel with the corresponding wheel at the other end and the periphery of one wheel at each end of the board projecting outside the surface of the board to engage the fabric passing thereover. Two of the wheels will project above the upper surface of the plate and the other two depend below the under surface, and all of the wheels are arranged to revolve in planes at an angle to the direction of movement of the fabric. The result is that when the wheels contact with the cloth, the teeth having slightly-beveled points, as indicated in Fig. 3, thc fabric will be shifted slightly, moving laterally a sufiicient distance to change the bends or folds at the edges and present a new surface at that point. The plate 12 is loosely thrust into the tubular fabric, as indicated in Fig. 1, and the material allowed to slide over the shaft 3, between which and the shafts 4 our invention is placed. In some instances, particularly in napping a heavy fabric, we prefer to employ a device consisting of a rack 18, having notches 19 to receive a rod 20, over which the fabric to be napped is carried. This rod can be raised or lowered, according to the weight of the material to be treated. We sometimes prefer to move the fabric laterally a greater distance than at other times, and this movement can be varied by altering the position of the rod 20.

In Figs. 4 and 5 we have shown a modified construction, which consists in providing a series of toothed guide- wheels 21 and 22, projecting upon opposite sides of the plate 23 and revolving in planes parallel with the direction of the movement of the fabric. In front of these guide-wheels we provide a series of toothed wheels 24 and 25, projecting upon opposite sides of the plate 23 and arranged to revolve in planes at an angle to the direction of movement of the fabric, resulting in a shifting1 of the fold or bend during the passage of t e material. This modification is designed particularly for use when the invention is employed independently of a napping-machine.

In Figs. 7 and 8 we have shown a plate 26, having a circular hole or opening 27, wherein a bushing 28 is fitted. Each end of the bushing is provided with an annular recess 29, adapted to receive a spring 30, having an outwardly-turned end 31, that fits within a socket 32 in the bushinor and is prevented thereby from accidenta movement. other end of the sprin is inwardly turned toward the center lof t e hole 27 and forms a` pivot for a bevel-edged wheel 33, Whose periphery projects beyond the surface of the plate 26 and is adapted to revolve in the plane at an angle to the direction of travel of the fabric. One of these wheels is mounted on each spring, and there is conse uently one on each side of the plate 26. T e opposite corner of the plate 26 is equipped with wheels and supports therefor corresponding to those shown in Figs. 7 and 8.

In this application we do not wish to confine ourselves to any particular construction or' arrangement` of these shifting devices, as the same are capable of various modifications without departmg from our invention.

We claim yas our invention- 1. The combination, with a fleecing or napping machine, of means for shifting the position of the folds or bends in the tubular fabric as it passes through the machine.

2. The combination, with a eecing or napping machine, of mechanism for imparting a The v lateral movement to the tubular fabric at the point where the bend or fold is made therein, for the purpose specified.

3. The combination, with a fleecing or napping machine, of devices operating in planes at an angle to the direction ,of movement of the tubular fabric, and arranged to engage the same and move the material laterally at the point where the bend or fold is made therein.

4. The combination, with a iieecing or napping machine, of toothed idle wheels engaging the tubular fabric, and arranged to revolve in planes at an angle to the direction of movement of the fabric and engage the same to shift the position of the folds or bends therein.

5. The combination, with a fleecing or na ping machine, of a suitable support, i le Wheels arranged in pairs on said support, and having toothed peripheries projecting beyond the surface of said support upon each side, arranged to revolve in planes at an an- Ole to the direction of the movement of the lfabric through said machine.

6. A device of the class described comprising a plate having openings therein, brackets secured in said openings, idle wheels journaled on studs in said brackets, there being a pair of wheels at each end of said plate, one wheel on each pair revolving in a plane parallel, substantially with the corresponding wheel of the other pair and at an angle to the other wheel of the same pair, and sald wheels rojecting beyond the surface of said plate, for the purpose specified.

7. The combination, with means for moving a tubular web or fabric len thwise, of means for shifting the' position o the bends or folds in the fabric during such lengthwise movement.

In witness whereof We have hereunto set our hands this 30th day of August, 1904.

FRANK CHATFIELD. JAMES STRUTHERS. In presence of- RICHARD PAUL, C. MACNAMARA.
