MACHINE FOR RAISING wir on FABRICS.
Application filed April 24, 1915. Serial No. 23,632.
by declare the following to be afull, 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. 1 i
This invention relates to machines for raising nap on fabrics and has for its primaryfobject to provide a construction in which the raising action may be eflected simultaneously in the direction of the warp of the fabric as well as transversely of the.
same, whereby an even and highly efficient raising action is obtained.
Other objects of the invention are to provide a machineof this character in which the fabric is conducted over two different groups of raising rollers which are rotatably mounted, partly in the direction of the warp and partly'in that 'of the weft of the fabric, in a traveling carriage movable to and fro transversely to the traverse of the fabric, and the raising rollers of oneof which groups are adjustable in vertical dira'ising action; I
With these and other ends in view my invention consists in the arrangement, construction and combination of parts; to be herein described and particularly pointed out in the appended claims.
In the drawings Figure 1 is aplan view of a machine constructed in accordance with the presentinvention, some parts of the guiding rollers for the fabric being broken oif for the sake of clearness; I V j Fig. 2' is a front elevation of the machine; .Igigft is a side elevation of the same; an I justable bearing rollers.

able power source. When this shaft is rotated it imparts a to and fro motion to the carriage 5. Transversely of this carriage, shafts 11 to 18 are'mounte'd on the same which are situated parall'elly to each other and in the same horizontal plane. The shafts 11 to 18 have securely placed thereon the raising rollers 19 and are rotatably mounted in'bear ngs 20.;of the carriage .5.
As is to be seenfrom the drawings, two raising rollers 19 are mounted on each of the transverse shafts. shafts 11 to 18 are arranged so closely to one another that the raising rollers of two adjacent shafts cannotbe arranged oppositely to. one another; the rollers are arranged in staggered relation so that the rollers of one shaft always face' free parts of the adjacent shaft. These rollers 19 execi'ite a raising action in the direction of the Weft threads of the fabric. j
The raising rollers 19 fastened to the form four rows on lines transverse to the direction of the axes of their shafts.- Between these rows spaces 21, 22, 23 are left which serve for the reception of another group of raising rollers, indi- -'cated by These 'thenumerals 24,125, 26. rollers are mounted in bearings 27 fastened to the'carriage frame and serve to eifect a fabric in the direction of-itswarp threads. v
The raising rollers 24, 25,26 are vertically adjustable in height. For this purpose the bearings 27 for the rollers are so construct ed as to possess an adjustability in vertical direction. Referring particularly to Fig. 1, the'bearings 27 consist of an upper part 28 comprising th'e-'brasses and cap-piece, and a lower part 29 forming a base fixed to the carriage frame. Both parts are of a screw bolt 80, which in one part is provided with right handed thread and in the other part with left' handed thread. The upper part 28 is provided with recesses 31 by which it is guided on corresponding extensions 32 formed on the base 29. By rotating the screw bolts '30 in one direction the upper parts of the bearings together with the rollers mounted therein are raised and by rotating the belts in the opposite direc'tion The rotation of the screw bolts may be effected by means of a rod; by inserting the same into recesses connected The raising rollers of both groups usually form one common horizontal contact surface for the fabric to be raised. Due to the adjustability of one roller group with respect to the other the raising action can be easily controlled at will. If the rollers 24, 25, 26 are so adj usted. as to raise above the upper contact surface formed by the rollers 19 the raising action will be more efficient in the direction of the warp threads of the fabric, While if the aforementioned rollers are lowered so far as to be under the upper surface of the rollers 19, these latter will execute a more efiective raising action on the fabric in the direction of its Weft threads. Besides, the rollers 24, 25, 26 can be lowered so far that they will no longer come into contact with the fabric on which the nap is to be raised, thus remaining in a non-operative position.
Underneath the raising rollers two electric motors 34 and 35 are fastened to the frame of the carriage 5, which serve to drive the rollers. 7
Motor 34 imparts rotation to the shaft 11 through the medium of an open belt 36 and motor 35 imparts rotation to the shaft 16 through the medium of an open belt 37 too.
The driving shafts of the motors 34 and 35 revolve in opposite directions. From the shafts 11 and 16 rotation is transmitted to the remaining shafts 12, 13, 14, 15, 17 and 18 by means of open and crossed belts, as shown, in such a manner that each two rollers which are situated one opposite to the other always rotate in opposite directions.
Mounted in brackets 41 at the front and the rear end of the carriage frame 5 are shafts 38 and 39, respectively. Shaft 38 is rotated by the motor 34 and shaft 39 by motor 35 through the medium of open belts 40.
The shaft 38 transmits its rotation to the longitudinal raising roller 25 by means of a half crossed belt 42, and in similar manner shaft 39 transmits the rotation imparted thereto to the longitudinal raising rollers 24 and 26 by means of two half crossed belts 43. According to this arrangement, roller 25 will rotate in a direction opposite to that of the rollers 24 and 26.
Pairs of rollers 45, 46 are mounted in the upper ends of standards 44 and serve to guide the fabric 47 through the machine in the direction of the axes of the raising rollers 19 and transversely to the rollers 24, 25 and 26. The guiding rollers 45, 46 are adjustable in height and for this purpose their bearings 48 are slidably mounted in any well-known manner in the upper ends of the standards 44. Thereby it is allowed to bring the fabric into contact with the raising rollers or to hold it free from the same. The fabric is further guided by means of guiding rollers 49 rotatably mounted in standards 50.
As to the guiding of the fabric I do not wish to be limited to the mechanism illus trated on the drawings, the fabric may also be guided in any other suitable manner; besides the rollers 45, 46 arranged at two sides of the machine, a plurality of guiding rollers may be provided between the same.
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.
