PILING- DEVICE.

Specification of Letters latcnt.

Patented Mar. 8, 1921.

To all whom it may concern:

Be it known that we, WILLIAM H Ron- ERTSON and FREDERICK WV. FISHER, c1t1zens of the United States, and residents of New Milford, county of Litchfield, and State of Connecticut, have invented an Improvement in Piling Devices, of which the following is a specification.

The object of this invention is to prov de a simple and practical machine for p1l1ng cloth or other materials in rope form into bins for aging or other purposes after having been subjected to prior treatmentsuch as boiling in connection with the bleaching operations. More particularly, the invention is intended for handling cloth in rope form received from the boiling keir of a bleacher and piling the same into bins for agmgand in which the rope-like material is laid in a zigzag form so that in being lald the strand of rope-like form is caused to lie across itself in what may be called a more or less criss-cross arrangement, and thereby providing air spaces through the piling fabric and which facilitates the aging operation.

The general construction of the improvement comprises an upright tubular guide universally jointed at the top to a suitable support and through which the rope-like fabric is guided downward, being fed into the upper end of the tubular guide by suitable guide means such as a grooved wheel, said tubular guide being combined with means arranged at ,right angles to each other for impartin thereto a reciprocating motion, whereby t e two motions at substantially right angles cause the tubular guide to swing into various oblique positions, the means for imparting reciprocation in one direction giving a relatively lesser number of reciprocations than are imparted by the reciprocating means for giving motion in the other direction, with the result that the lower guiding end of the tubular guide is caused to traverse back and forth in a zigzag manner where there may be, for example, nine complete reciprocations in one direction to one reciprocation in the other direction with the result that the rope-like cloth is laid back and forth along the length of the bin with the strands of each layer crossing the strands of the previous layer.

The invention further compreliends details of construction which together with the features above stated are more fully described hereinafter and pointed out in the claims.

The invention will be better understood by reference to the drawing in which is shown a perspective view illustrating the general elements which enter into the construction.

2 is the upright tubular guide for the cloth in rope form. This tubular guide may be formed of wood or metal, as preferred, and is hung at the top upon a universally jointed support 3 connecting it with a joist or suitable stationary part I of the building, from which it will be understood that the said tubular guide may be swung in any direction at its lower and free end which is arranged above the bin 27, so that the ropelike fabric 6 which passes down through the guide may be delivered into the bin as hereinafter more fully explained. 5 is a grooved wheel over which the cloth rope 6 passes and from which it is guided downward into the open end of the tubular guide 2, the said guide wheel 5 being arranged close to the upper end of the guide 2 and relatively close to the universally. jointed support 3. 7 is a weighted rollerwhich rests upon the fabric in the groove of the guide wheel 5 to in sure its being properly guided therein, and said wheel 7 is journaled in an arm 8 pivoted relatively to the joist or stationary frame 4, whereby the weighted roller 7 may continually rest upon the rope-like fabric while at the same time having more or less freedom to adjust itself to any irregularities in the thickness thereof.

9 is a horizontal shaft carried in suitable bearings 10 which may be suspended by any suitable hangers which are commonly employed in factories. At one end of the shaft 9 is arranged a crank wheel 11 having the crank pin 12 and at the other end said shaft is provided with a bevel gear 25. A second horizontal shaft 17 similarly supported in journal bearings 18 is provided at one end with a bevel pinion 24 meshing with the bevel gear 25 of the other shaft and has its other end provided with a crank wheel 19 having a crank pin 20. The shaft 17 is also provided with fast and loose pulleys 26 adapted to be driven by a power belt for putting the shafts 9 and 17' into motion or for permitting them to come to rest according as to whether the belt is shifted to the fast or to the loose pulley, such featuresbeing well known in factory equipments, and will need no further description.

As will be seen, the crank wheel 11 provides a much greater throw to the crank pin 12 than is obtained by the crank wheel 19, but on the other hand, the crank wheel 19 will make a greater number of revolutions per minute than will be made by the crank wheel 11. The crank pin 12 has jour' naled to it a block 16 and to this block is hinged a connecting rod 13 whose other end is connected to a block 15 hinged to a band 14 surroundingthe tubular guide 2, at some distance from its pivotal support 3. The blocks 15 and 16 provide universally ointed connections between the crank pin 12 and the band 14 of the guide 2, so that while making a direct thrust or pull between the crank pin and the tubular guide, the latter may be shifted at substantially right angles to said thrust or pull. Similarly the crank pin 20 is connected with the band 14 of the tubular guide by means of a connecting rod 21 which has universal jointed connections 22 with the band and 23 with the crank pin, so that it may impart a direct thrust or pull while at the same time permitting the transverse swinging by the crank pin 12 and rod 13. As the crank wheel 19 makes so many more revolutions'than the crank wheel 11, it is manifest that the tubular guide 2 will reciprocate in its swinging motion many times in one direction relatively; to each reciprocation in the other direction. Thus, the reciprocations of the guide 2 under the action of the crank wheel 11 is represented by the double pointed arrow 00 y, whereby with this single reciprocation by the crank 11, the

guide is given 10 reciprocations in the other direction as indicated by the dotted lines 8 29 arranged in the bin 27. In making these reciprocations s t, a series of reciprocations will be made when the guide 2 traverses in the direction of the arrow y and then a second series of reciprocations s 25 will be made when the tubular guide 2 reciprocates in the direction of the arrow as, and these two sets of reciprocations s t will alternate in position and will cross as indicated by the dotted lines, as shown. It is manifest, therefore, that the fabric in rope form will be laid in the bin in the zigzag crossing form, as shown by these dotted lines .9 t and following the direction of the arrow heads placed thereon, so that each zigzag strand crosses the previously laid zigzag strand tails may be changed or modified in numerous ways While maintaining the same operations upon the guiding means for the fabric, it being understood that the essential feature inthepreferre'd form of the invention resides in providing a guide for the fabric having a relatively fixed position and a movable guide'for the fabric adjacent to the bin and combined with means for imparting to it a greater number of reciprocations in one horizontal direction than are imparted to it in a transverse direction. lVlore'gcnerically stated, the invention may be considered as embodying a fabric guide combined with means to reciprocate it in a horizontal direction in two directions and in which the reciprocations in one direction are relatively greater than the reciprocations in the other direction in any given period of time, and in which further suitable provision is made for guiding the fabric to the upper portion of ithe reciprocating fabric guide, whereby the fabric may be properly fed into and piled in the bin.

It will now be apparent that we have devised a novel and useful construction-which embodies the features of advantage enumerated as desirable, and while we have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that we do not restrict ourselves to the details, as the same are susceptible of modification in various particulars 'without departing from the spirit or scope of the invention.

Having thus described ourinvention, what we claim as new and desire to secure by Letters Patent, is

1. A piling machinecomprising a receptacle for receiving the piled material, a substantially fixedly positioned guide for guiding the material in strandor rope form to the receptacle, movable means through which the'material is guided arranged between the fixedly positioned guide and the receptacle, and power means for imparting reciprocating motions transversely to the movable guiding means, said motions being at substantially right angles and the reciprocations in one direction being greatly in excess of the reciprocations in the other direction.

2. The invention according to claim 1,

wherein the movable guiding means consists of a long upright tubular guide pivoted on a universal joint adjacent to the fixedly p0- sitioned guide and having its lower end movable over the receptacle.

3. The invention according to claim 1, wherein the power means for receiprocating the movable guiding means comprises two cranks geared to rotate in planes substantially at right angles to each other and one of the cranks rotating with a greater number of revolutions than the other, and connecting means from the respective cranks to the movable means for guiding the material.

4. The invention according to claim 1, further having the fixedly positioned guide in the form of a grooved wheel in which groove the material is guided, and a weighted pressure wheel movably supported to press upon the material being guided in the groove of the guide wheel.

5. A piling machine consisting of a bin, combined with a guide having a relatively fixed position at a higher elevation than the bin and over which the material in rope-like form is fed, a movable guide through which the material is guided arranged between the relatively fixed guide and the bin, and power means for imparting an irregular movement to said movable guide, said movement having a relatively greater number of lateral reciprocations in one horizontal direction than in the other, whereby the material being treated will be caused to lie in the bin in a criss-cross arrangement.

6. The invention according to claim 5, wherein the movable guide comprises a hingedly supported tubular structure through which the material passes, and the power means for moving it consists of two suspended crank shafts at right angles geared together to rotate at relatively different speeds, means to drive the shafts, and connecting rods from the crank shafts to the tubular guide structure whereby it is reciprocated in two directions at substantially right angles, the number of reciprocations in one direction being greater than in the other direction during any given period of time.

7. A piling machine consisting of a substantially fixedly positioned guide for the material in rope-like form, a receptacle for receiving the material, a movable guide hinged at its upper end near the fixedly positioned guide, and power devices for imparting an irregular movement to the movable guide to cause the materials to be laid in the receptacle in open overlapping condition.

In testimony of which invention we hereunto set our hands.
