MACHINE FOR RAISING NAP ON FABRICS.

Specification of Letters Patent. Patented July 19, 1921.

Application filed July 23, 1919. Serial No. 312,867.

T all whom it may concern:

Be it known that T, Jones Rncou'r, Jr., manufacturer, a subject of the Queen of the Netherlands, residing at Maastricht, No. 18 .Kleine Lovierstraat, in the Kingdom of the Netherlands, have invented certain new and useful Improvements in Machines for Raising Nap on Fabrics; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in machines for raising nap on fabrics of the character in which the raising action may be effected simultaneously in the direction of the warp of the fabric as well as transversely to the same, such as disclosed for example in my Letters Patent of the United States No. 1217129 of February 20, 1917.

The primary object of the present invention is to provide a machine of this character in which the raising rollers and the driving means for the same are mounted in a fixed frame, while the fabric is being guided through a traveling carriage which is movable to and fro on the fixed frame transversely to the traverse of the fabric.

Another object of the invention is to provide in said machine means for deriving the reciprocating motion of the traveling carriage from the driving mechanism for the raising rollers.

A still further object of the invention is to provide the said machine with means for converting the reciprocating motion of the traveling carriage into a constant rotary motion which in turn is made use of for driving the feeding rollers of the fabric.

lVith these and other ends in view my invention consists in the arrangement, con struction and combination of parts to be herein described and particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a front view, partly in section, of the machine constructed in accordance with the present invention.

Fig. 2 is an end view of the same, partly in section. v

Figs. 3 and 1 are detail views of parts of the gearing.

Figs. 5, 6, 7 and 8 are views of further details of the gearing.

Referring now to the drawings, in which similar numerals of reference indicate corre-v spending parts, 5 designates a fixed frame in which are mounted the raising rollers 6 and 7 The raising rollers 6 are arranged with their axes in the direction of the traverse of the fabric 8, i. c. in the direction of the warp, and the raising rollers 7 transversely of the traverse of the fabric, 71. e. in the direction of the weft. The rollers 6 are preferably eight in number (comprising two groups of four rollers) and the rollers 7 are two in number. In the. groups of the four rollers 6 the pairs of rollers lying on opposite sides of the longitudinal axis of the machine turn outward, while the rollers 7 turn in a direction opposite to the direction in which the fabric 8 passes through the machine. The mechanism for rotating the raising rollers is driven from a main pulley 9, adjacent to which is mounted an idle pulley 10. The pulley 9 is driven from any suitable source of power. Both pulleys 9 and 10 are mounted on a shaft 11 from which the rotation is transmitted through belts to shafts 12, 13 and 141 which are suitably mounted in the frame 5 in any well-known manner. The shafts 12,13 and 11 are in driving connection with the raising rollers 6 and 7 by means of belts, toothed and bevelwheels which cause rotation of the raising rollers in the desired direction. As in my Patent No. 1217129 before referred to, the transverse rollers 7 are vertically adjustable with respect to the fabric 8, in order to obtain an increased raising efiect either in the direction of the war the weft of the fabric. To enable this, the rotation of the shaft 14 is transmitted to vertical shafts 15 by means of bevel-gears 16. The upper ends of the shafts 15 are in turn in driving connection with the shafts of the rollers 7 by means of bevel-gears 17. Each shaft 15 consists of two parts which are longitudinally slidable one within the other and which are journaled in bearings 18 and 19, respectively. The bearings 19 are mounted on brackets 20 which support the shafts of the raising rollers 7 and which are vertically adjustable in guides formed on the frame 5. The lower ends of the brackets 20 are engaged by threaded spindles 21 which are guided in internally threaded housings 22 which are fastened to the frame 5. Below the housings 22 the spindles 21 are provided with worm wheels 23 which are in engagement with worms 24 fixed on a shaft 25.. This shaft is journaled the or in the direction of frame 5 and is provided at its free end with a hand wheel .26 by means of which'the shaft may be rotated in one direction or the other. It is evident, that by rotating the shaft 25, the spindles 21 will be screwed-upward or downward, thereby elevating or Loosely mounted on shaft 12 near each i of its ends is a sprocket-wheel 27 whichcan be coupled with shaft 12 by the aid of a suitable clutch controlled by a lever (not shown). The sprocket-wheel 27 is connected by an endless chain 28 to another sprocket wheel 29 which is fastened to one end of a shaft 30 journaled in a bearing 31 (Fig. 3)

supported by the upper part of the frame 5.

The other end of shaft 30 is provided with a sprocket-wheel. 32 to' which is adapted 'a chain. 33 which passes around a sprocket wheel 34 the shaft of which is mounted in a bearing 35 (Fig. 3) supported bythe' frame 5. The chain 33 is provided with a stub shaft 36. oval slot 37 which is formed in a. beam-38 of the traveling carriage 39 which guides the fabric 8. The stub shaft 36 is movable up and down in the slot 37 and'when running with the chain 33 imparts a to and fro motion to the carriage 39. The carriage 39 is provided with grooved wheels 40 by means offwhich it travels on rails 41 which are supported by the frame Feeding rollers 42 and idler rollers 43 are serve to guide the fabric 8 through the machine in the direction of the axes of the raising rollers 6 andtransversely to the rollers 7. I

The reciprocating motion of the carriage 391s converted into a constant rotary motlon guiding rollers 42. To this end,'the carriage 39 is provlded with arms 44 in, which 1s rotatably mounted ashaft '45 (Fig. l).i"l.lie shaft 45 carries on its intermediate part a spur-wheel 46 which is in engagement with a rack-bar 47 which is fastened toa bracket 48'of theframe 5. (Fig. 1). On both sides of the spur-wheel 46, the shaft 45 has loosely mounted thereon bevel wheels 49. .Fastened rigidly to and concentrically with the bevelwheels .49 are ratchet-wheels 54 which have oppositely directed teeth (see Figs. 4, 5 and 7). These ratchet-wheels54 are engaged by pawls 55 which are'swingingly mounted on pivots 56: carried by segments 57 which are i fastened to the opposite'side faces of the spur-wheel 46 or the shaft 45', respectively. The pawl55,=shown in Fig. 6, cooperates with the ratchet-wheel. .54, shown Fig. 5,

This shaft projects into an as stated.

and the pawl 55, shown in Fig. 8, cooperates *with the ratchet-wheel 54, shown in Fig. 7.

The pawls are held against stops 58 of the segment 57 by means of springs 59. The stops have angular faces 60, 61. The pawls lie against the faces 60 when in operation, 2'. e.

whenengaging the teeth of the ratchettermittently rotated by the reciprocating movementof the carriage, the bevel-wheels 49 are alternately rotated in oppositediree tions through the medium of'the described ratchet-Z and pawl-mechanisms; The constructionof these mechanisms, which forms no part of this invention, mayalso beof any other well-known kind.

with a common bevel-wheel 50 to which a constant rotation in one direction is imparted through the alternate rotating of the wheels 49in opposite directions. The bevelwheel 50 is fastened to one end of a shaft 51 which is rotatably mounted in the frame of the carriage 39 and which, on' itsother end, carries a sprocket-wheel 52 around which )asses"a-chain 53 (Fig. 1) which transmits thenecessary rotation to the guiding-rollers 42 for the fabric 8. 7

. lVhen the raising rollers 6 and 7, driven from the pulley 9, are rotating and the sprocket-wheel 27.is coupled with'the shaft 12., so that the traveling carriage 39 is given its reciprocating motion through the mechanism described, each point ofthe fabric moves on a regular zigzag line across the mountedm the frame of the carriage 39 and 1 raising rollers, whereby a highly efficient raising action is attained. By not coupling the sprocket-wheel 27 with the shaft 12, the carriage 39 can be held in non-operative position, in which case each point of the I fabric will travel on a straight line across which is made use of for propelling the the raising rollers.

In-order'to give the fabric thenecessary forward motion in the last-mentioned case,

one end of the shaft carrying the main pul- *-ley 9'is provided with a pulley 62, and

another pulley 63 is fastened to the shaft of one of the feeding-rollers 42. These pulleys 62 and 63 can be brought into driving connection by means of ahalf-crossed belt 64; The belt 64 is normally thrown off and is only put on when the sprocket-wheel 27 :is uncoupled from the shaft 12 and it is dethe fabric on a straight line sired to move 'without interfering with theop'eration of the-machine; In order to avoid undue friction, most bearings are constructed. as ballor roller-bearings. The belts and pulleys of the driving mechanism for the raising rollers are arranged in such a manner that all parts are easily accessible and that the belts may be conveniently thrown off. 1

By mounting the raising rollers and the driving means for the same in a fixed frame or base instead of in the traveling carriage such as is the case for example with the machine of my aforementioned prior Patent No. 1217129, the traveling carriage which must be moved to and fro, it rendered much simpler and of much less weight. Therefore, the power necessary for executing the movement of the carriage is also much reduced. Besides, the entire machine can be driven by a single belt from any suitable source of power (vapor, electricity, gas). The traveling carriage needs no special driving means, its reciprocating movement being derived from the propelling mechanism for the raising rollers, and the reciprocating motion being in turn utilized for causing the rotation of the fabric guiding rollers.

It is obvious that various modifications may be made in the construction shown and above particularly described within the principle and scope of my invention.
