' 1 Claim. (01. 26-14) This invention appertains tonew and useful improvements in means for cutting or slitting various kinds of double pile fabric.

' The principal object of this invention is to provide a cutting mechanism for cutting or splitting double piece goods as they are woven in the looms.

Another important object of the invention is to provide a cutter for cutting or splitting double piece fabrics as they are delivered from the loom wherein a cutter is employed which is self-sharpening and requiring only occasional attention.

Another important object of the invention is to'provide a cutter of the above type which will efficiently cut fabrics woven from any grade or variety of material.

Other important objects and advantages of the invention will become apparent to the reader ,w of the following specification.

In the drawings:-

Figure l represents'a front elevational view of the cutting mechanism.

Fig. 2 represents a top plan view of the cutting mechanism.

Fig. 3 represents an end elevational view of the mechanism.

Fig. 4 represents an end elevational view of the mechanism and part of a loom looking at the opposite end from that shown in Fig. 3.

Fig. 5 represents a cross sectional View taken substantially on line 5-5 of Fig. 2.

Fig. 6 represents a diagrammatic view disclosing the manner in which the double pile fabric is split by the knife.

Referring to the drawings wherein like numerals designate like parts, it can be seen that Figs. 3 and 4 show parts of a loom with numerals 55 indicating end plates between which the shafts 6-7 are mounted, and on which the rolls 40- 8-9 are respectively mounted.

In Fig. 6, it will be observed that numeral 16 represents the reed of the loom and as is further shown in this figure, numeral 11 represents the fabric in double pile as it leaves the loom and is bent between the guide bars 12 and 13, where it is split by the endless cutter 14, having one end sharpened as at 15. One section a of the fabric passes over the roll 9 and back over the supplemental-rolls 15 and 1'7 while the remaining sec- 59 tion 1) passes over the lower roll 8 and back over the smaller roll 18.

In describing the present invention, numeral 19 generally refers to the cutting mechanism which is swingable and operates simultaneously with the reed 10. In other words, when the reed takes a stroke'toward the cutting mechanism, the knife 14 is removed or retracted from the fabric and. when the reed mechanism 10 returns for another beat on the fabric, the knife is moved toward the stationary fabric and cuts through the same while it is stationary.

Journalled through the end plates 55 is the shaft 20 which carries the laterally disposed block 21 disposed between the pair of parallel flanges 22-22 on the lower end of the arms 23. Set screws 24 extend through the flanges 22-22. The upper end of this arm 23 carries a pair of rockable levers 25-25, each being provided atone end with a set screw 26 which is adjustable against the projection 27 on the upper end of the arm 23 whereby the tension of the sharpening rotors 28 on the remaining ends of the rockers 25-25 can be adjusted properly with regard to the cutter band 14.

Vertically extending bars 30-30 are secured at their lower ends as at 31 to the shaft 20 adjacent the plates 5-5, numeral 32 representing an elongated horizontally disposed channel which is provided with slots 33 adjacent each bar 30 to receive the bolts 34 projecting from the adjacent bar 30. Set screws 35 are provided on the bar 30 for engagement with the beam 32 in the manner shown in Fig. 1, whereby the beam can be adjusted.

At one end, the beam 32 supports a platform 36 carrying the electric motor 37, the armature shaft 38 of which is equipped with a worm 39 meshing with the gear 40 on the shaft 41, which shaft is equipped with the pulley 42.

At the opposite end of the loom frame, that is adjacent the opposite end Wall 5 is the complementary pulley 43, and as is clearly shown in Fig. 2, the cutter band 14 is trained over these pulleys .42 and 43. The pulley 43 is carried by the stub shaft 44 which has a screw 45 threaded therethrough, and equipped with a hand wheel 46 to facilitate rotation thereof. This stub shaft 44 is equipped with a laterally disposed arm 47 pivotally connected as at 48 to the block 49, the block being secured to the aforementioned beams 32, and obviously, by operating the screw 45, the pulley 43 can be swung to the proper position for either returning the band 14 to a proper position on the pulley, or else permitting displacement or replacement of the band.

Numeral 50 represents a screw, whereby the pulley can be'adjusted longitudinally with re-' spect to the "beam 32. As is clearly shown in Fig. 4, it can be seen that the upper rolls 8 and 9 respectively have their L-shaped blocks are arranged horizontally on the beam 61 and each is provided with a pin and slot connection 62' through the beam, 61 whereby the roller 63 in its bifurcated end adjacent the cutter band can be adjusted to set the position of the band. A set screw (i4 is provided 7 on the depending portion of each of the blocks'60,

whereby the block can be placed in; the proper position. Numeral 65 represents a guide for the cutter band 14.

It can now be seen, that the upper fabric guide bar 12 can be adjusted by the screwsjfifi to pass the'fabric in its double p le formation properly to the blade 14, and as before'stated,'on the retracting motion of the mechanism 1 0 the blade 14 is swung with the entire assembly 19' on the shaft 20, This is accomplished by a crank and rod connection, (one or more)v between the shaft 20 and the shaft 67, this last-.mentioned shaft being associated with the reed mechanism 10 (see Fig. 3), insuch a manner as to cause the assembly 19 to move toward the uncut portion of the fabric as the reedrnechanism recedes from its beating position with the fabric. The blade is moved out of contact with the cloth when the reed beats the filling or weft up into place. More specifically, the shaft 67 is the crank shaft of the loom and operates the beam of the feed mechanism by means of the rod 66' and eccentric 66 simultaneously with the operation of the reed by the connections l0 between the shaft 6'7 and the reed. A power driven pulley, denoted by A, is connected for driving the shaft 67 by the meshing gears B and C. I

Obviously, during this cuttingoperation, the blade 14 is travelling and this motion is accomplished by the rotation of the pulleys 42, 43 by the motor 37.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is:- t

In combination; a loom for weaving double pile fabrics including a reed motion, an endless cutting band, means for driving the band, said band being positioned to travel in a direction transversely to the woven fabric strip, a carriage for said cutting band, and a connectifln between the said reed" motion and the carriage, whereby the carriage will be moved to carry the cutting band in a direction longitudinally away from the fabric strip when the reed is in the act, of beating up the weft threads.
