MACHINE FOR EXAMINING TEXTILES.

Specification of Letters Patent.

Patented July 16, 1918.

Application filed November 26, 1917. Serial N 0. 203,997.

To all whom it may concern:

Be it known that I, FREDERICK E. PARsLon, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain newvand useful Improvements in Ma-- chines for Examining Textiles; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates broadly to improvements in machines for examining textiles, such as woolens, cottons or silk cloths of any texture, and more particularly to an apparatus for unwinding, examining, measuring and refolding cloth, which will require only. one operation.

To those skilled in the art to which this invention belongs it is well known that it is necessary to closely examine all cloth before it cut up in order to determine Whether or not it is in any way defective. The usual method of doing this is to unfold the fabric and drape it over a suitable bar or the like before a strong light, either artificial or natural, this being customarily done by hand.

Therefore, it is the object of the present invention to accomplish this examination with a saving of time and labor, this being readily accomplished in 0118' machine con structed in the manner illustrated.

An object of the invention subsidiary to the principal object is to provide a novel arrangement for automatically folding the cloth after the examination thereof the speed of such folding operation being proportionate to the rapidity of the examination.

A still further object of a minor nature is to provide a measuring instrument in connection with the other features whereby the amount of cloth examined can be-accurately determined. 1

Another object is to provide means for controlling the speed of operation of the parts which move the cloth into position for examination thereof.

Still another object is to provide a device whereby double folded cloth may be spread to its full width before being disposed for its examination.

lVith these and other minor objects and advantages in view the invention resides in the novel features of construction. combination and arrangement of parts which will be hereinafter more particularly described and claimed, and shown in the drawings wherein:

Figure 1 represents a front elevational view of a machine constructed in accordance with' my invention.

V Fig. 2 is an end elevation, partly in section. of the machine illustrated in Fig. 1.

Fig. 3 is a plan view of this improved machine with certain of the elements removed for convenience in illustration.

Fig. 4 is a vertical transverse section taken on the plane of the line H of Fig. 1.

Fig. 5 is a detail vertical longitudinal section on the line 55 of Fig. 9, showing particularly the means for varying the speed of operation of the cloth feeding means.

F ig. 6 is a detail sectional view taken on the line 6-6 of Fig. 2, and

Fig. 7 is a fragmentary elevational View of the means for adjusting the cloth examining member.

The invention comprises broadly a supporting frame of a suitable type, a cloth examining member pivotally mounted on said frame, means for moving the cloth over said examining member, means for measuring the quantity of cloth so moved and .means for folding the examined cloth. All

of these features of the invention will be independently described and their relation to one another explained.

A supporting base may be of any suitable or convenient design, but that illustrated has been found to work advanta geously. It comprises a pair of end frames 1, each of which is constructed substantially of three angle bars arranged in the form of a triangle, one of the sides 2 of which rests upon the ground thereby disposing the apex of the triangle upwardly. The sides 3 of the frames 1 are braced intermediate their ends by the bars 4, and the base bars 2 are connected with similar channeled bars 5 each serving to space the end framcsapart, and at the same time holding them in rigid relation. p

The upper endsor apices of the frames are connected by trunnions 6 of a feed roll 7, said trunnions being journally mounted in suitable bearings carried by said end frames. A textile examining member S is tiltably mounted on the supporting base by means of said trunnions 6, said examining member comprising a rectangular frame 9 preferably formed of angle bars which 7 carry a transparent plate 10 such as of glass.

The opposite end bars of the frame each has a segmental plate 11 secured thereto, said plates being provided with alined openings for the reception of said trunnions 6.

The arcuate edges of the plates 11 are cut to provide rack teeth which mesh with the teeth of pinions 12 that are carried by a shaft 13 also journally mounted on the end frames 1. Also fixed on the shaft 13 is a ratchet wheel 1% with which a pawl 15 engages to prevent retrograde movement'of the shaft. By this arrangement the examining member 8 may be tilted from a horizontal. to. a substantially vertical position or to. any intermediate point and held thus.

This movement is obviousl r effected b Y rota-,

tion of the shaft 13 in the proper direction which causes the segmental plates to shift around their axis. The examining member being pivoted intermediate its .ends and nearer one end than the other, the overbalanced portion thereof will tend to cause the shaft 13 to revolve in one direction, said tendency being overcome by the pawl and ratchet arrangement.

The cloth to be examined is conveyed across the upper face of the transparent plate 10, this movement being facilitated by a guide roller 16 journaled in suitable bearings carried by the upper end of the frame 9 of the member 8. This roller 16 is of course positioned transverse of the direction of the movement of the cloth, and at the opposite end of the frame is similarly positioned a second guide roller 17, this roller being journally mounted in brackets 18. The freedom of movement of the roller 16 is controlled by a spring tension device consisting of a wheel 19, a leaf spring 20 and a set screw 21 for adjusting the spring toward and away from the wheel. These parts are shown in -lTigs. 1, 2, and l.

The brackets 13 also have a third guide roller 22 carried thereby, said guide roller together with the roller 17 and the feed roll 7 cooperating to move the cloth from the upper edge of the frame 9 to a point beneath said frame where it can be operated upon by the folding means to be hereinafter more particularly described.

A plurality of feed belts 23 are disposed around the feed roll 7 and the guide roller 22 as shown, theupper stretchlieing engaged by the guide roller '17. The lower stretches of the belts are engaged by tensioning devices, one of which is provided for each of the belts. These ten'sioning devices are mountednpon a shaft 2a, the latter in turn being'carrie'd by the segmental plates 11. Each device consists of a roller 25 for engagement with a belt 23, an arm 25 for "pivoting'said roller-.25 to the sh aft 2-f, and

a coiled spring 27 engaged with said arm 26 for moving said roller toward the belt.

The feed roll 7 is revolved by any suitable power supplying machine, belted or otherwise connected with a pulley wheel 28, which is mounted on a stub shaft 29 carried by one of the end frames 1. The pulley wheel 28 is preferably clutched to theshaft to be controlled at the will of the operator of the machine as shown by the arrangement at 30 in Fig. 1. This clutch arrangement is actuated by the longitudinal sliding movement of a foot bar 31 which is disposed on one of the brace bars 5 of the supporting base. It will be noted from Figs. 1 and 3 that the bar throughout its length is provided with a number of sets of projections 32's0 that the same may be actuated by the operator regardless of his position with respect to the ends of the machine. The movement of the bar 31 is obviously transmitted to the clutch mechanism by the intermediately pivoted lever 33 mounted upon a bracket 3-1 projecting from one of the end frames 1.

The speed of rotation of the feed roll 7 with respect to the pulley wheel 28 is readily varied by a suitable friction clutch comprising a pair of plain gear wheels 35 and 36 mounted respectively upon the shaft 29 and one of the trunnions 6 of the feed roll, and a shiftable friction gear 37. The gear 37 consists of a pair of circular plates 38 spaced apart to receive the gears 35 and 36, said plates being disposed on a stub shaft 39. The plates 38 are moved toward each other so as to tightly engage the friction wheels by an adjustable spring 10.

The shaft 39 being carried by a lever 41-1, the friction gear 37 is readily moved toward oraway from either of the shafts 6 and 29. Such movement of the lever 11 is controlled by either one of a pair of bell cranks -12, one

of which is fixed to each end of a shaft 43 that extends longitudinally of the machine and across the front thereof. One end of each bell crank forms a handle while the other arm of one is linked as at 14: to the free end of the lever &1. Thus the speed of the feed roll can be controlled from either end of the machine.

The lever 41 is held against jarring out of its adjusted positions by the arrangement shown in Fig. 6 which consists of a spring pressed plate 45 and a strip of non-metallic anti-slipping material 4:6, both of which aresecured to the end frame by the bolts 47. The lever a1 is frictionally held between the plate 4E5 and the strip 16.

Inasmuch as most woolens and suitingmaterial are rolled or folded in double thick ness, it must be unfolded before being exam; med, therefore I have provlded a Ll-shaped.

guide rod 48, the arms 'of which are pivotally mounted on the ends of brackets lti which extend from the opposite ends of. the

frame 9'. The ends of the arms which extend through said brackets 49'arethreaded to receive nuts whereby the rod may be held in adjusted positions with respect to the frame 9.

The cloth as it moves over the examining member 8 is measured by any conveniently formed measuring device such as that shown at 51. This device is geared to the feed roll 7 in any desirable manner, it being mounted on one of the end frames 1 adjacent one of the trunnions 6 by means of a bracket After the cloth has been moved over the examining member by the feed roll and the feed belts it is folded upon the floor beneath the machine or upon a. suitable table disposed thereunder. This folding device consists of an oscillatory plate 58 hinged to the shaft 13 and extending the full length of the machine. The plate is oscillated by means of a crank 54 connected with the same by a pitman 55 as shown clearly in Fig. 1. The crank is connected with a shaft which is continuously revolved with the feed roll 7, it being connected therewith by a belt 56. Thus whenever the speed of rotation of the feed roll is changed, the oscillation of the plate 53 will be proportionately varied.

The cloth as it passes over the feed roll is guided on to the oscillatory plate 53 andhcld against movement between said roll and the shaft 13 by a plurality of guard strips 57, the opposite ends of which are disposed around the feed roll and shaft 13 respectively. Said feed roll is covered by any suitable friction material, such as fine sandpaper or felt to prevent slippage of the cloth.

The operation of my invention with double folded cloth is as follows: The cloth examining frame is tilted to the convenience of the operator or to permit the strongest light to be thrown through the transparent plate 10, such adjustment of the frame being accomplished as hereinbefore set forth. The bolt of cloth is then disposed adjacent the guide 48 and the end of the strip disposed between the arms of said guide with the seam thereof resting in its apex. The

portion of the cloth on each side of this fold will then lie on the arms of the guide, after which the end of the strip of material may be moved upwardly, over the guide roller 16.

and across the upper face of the member 8, fter which it is directed around the guide roller 17 and on to the upper stretches of the feed belts 23. Continuation. of movement of the end of the strip of cloth to be examined disposes it on the feed roll 7 and oscillatory plate 53. Vfhen the rotation of the feed roll 7 is begun by actuation of the clutch 30 the cloth is moved across the transparent plate 10 to permit the light disposed beneath the same to shine through the cloth and thus permit detection of defects therein. Thus the cloth is automatically unpackaged and after the examination is complete is folded into a convenient and uniform pile. As some cloth can be examined much more rapidly than others, therefore the above described means for varying the speed of rotation of the feed roll has been provided.

The simplicity of this machine is obvious from I examination of the accompanying drawings and its effectiveness is believed to be thoroughly evident after an examination of the drawings and the accompanying description. I l
