PATENT RUDOLPH GRAEBER, OF CHEMNITZ, GERMANY, yASSIGNO'R TO THE FIRM SCHUBERT 86 SALZER, AKTIENGESELLSCHAFT, OF CHEMNITZ, GERMANY.
REELER-BAB STRAEIN ING DEVICE.
(GRANTED UNDER THE PROVISIONS 0F THE ACT0F MARCH 3, 1921, 4l STAT. L., 1313.)
To all whom t mayV concern.'
Be it known that I, RUDOLPH GRAEBER, a citizen of the German Empire, residingV at Chemnitz, Germany, have invented certain new and useful Improvementsdin Reeler- Bar Straining Devices (for which I have filed an application in Germany on June 22nd, 1902, Patent No. 338,043), of which the following is a specification.
My invention relates to cloth-reeler-bar or the like and more particularly to a straining appliance for the cloth-reeler-bar of shuttle-embroidering machines.
Such cloth-reeler-bars are made either of wood or of thin iron-or steel plate. The wooden reeler-bars of the older type have proved efficient in the case of narrow machines. For machines of a greater width such as have recently come into use, metal tube-reeler-bars have been employed.
The cloth-reeler-bars employed up to the present were provided at both ends only with means for stretching the cloth. In view of the very considerable working length of modern machines this is not sufficient. It has been found that in consequence of the torsional moment the tension is considerably diminished in the middle part and that the unequal stretching of the material results in the cloth being embroidered in an irregular manner, the pattern not running straight across the breadth.
This drawback might be removed to a certain extent by increasing the thickness of the reeler-bar walls or the diameter of the reeler-bar. Such changes however involve other drawbacks. It is one object of my invention to avoid all these drawbacks. To this end I provide the reeler-bars, in addition to or in place of the straining means arranged at both ends, with other straining means engaging the reeler-bar in one or several intermediate points.
In the drawings axed to this specification and forming part thereof three modifications of a reeler-bar embodying my invention are illustrated by way of example,
Fig. 1 being a front elevation, partlyin axial section, of the first,
Fig. 2 a front elevation of the second, and
Fig. 3 an axial section of the third form,
While Fig. i is an elevation of a ratchet disc and pawl.
Referring to Fig. l of the drawings, 1 is the frame and 2 is the cloth reeler-bar located in bearings fixed to said frame. 3, 3 are end straining devices in form of ratchet discs cooperating with pawls (not shown). 4 is a short axle supporting theright hand end of the reeler-bar and 5 is a shaft .extending through the left hand ratchet disc into the center of the reeler-bar and having a sleeve 6 xed to its inner end, said sleeve being firmly vconnected with the reeler-bar by means of screws. l7 is another ratchet disc fixed to the outer end of shaft 5 and cooperating with a pawl 12. 8 is an intermediate bearing for the inner portion of shaft 5. This device operates as follows: the fabric to be embroidered having been fixed to and wound up on the reeler-bar, the middle straining device is actuated by manually turning the disc 7 and fixing it in straining position by aid of the pawl cooperating therewith. In this manner the middle portion of the fabric is stretched in a uniform manner, all folds being removed therefrom. After this has been effected, the end discs 3, 3 are turned and fixed in straining position by aid of the paWls appertaining thereto, whereby the lateral portions of the fabric are stretched also to perfection. If necessary, the middle portion may now be stretched once more by turning disc 7.
If a reeler-bar in two parts is employed, the sleeve 6 may at the same time serve as a coupling for the two halves.
In the modification disclosed inFig. 2 straining is effected in four points. The short axle 4 shown in Fig. 1 is here replaced by another shaft 5 extending into the reeler-bar from the right hand side and carrying a sleeve 6 at its inner vend and a ratchet disc 7 at its outer end. Obviously this arrangement will allow of a still more perfect straining of the fabric.
If it be desired, in the case of reeler-bars of extraordinary length, to stretch the fabric in more than four points, the arrangement shown in Fig. 3 may be made use of. Here the shaft 5 is hollow and another shaft 9 extends through it and through the sleeve 6 fixed thereto farther into the reeler-bar, aV sleeve l0 being fixed to the inner and a ratchet disc ll to the outer end of shaft 9. The sleeves 6 and l0 are ixed to the reeler-bar. By i'irst turning the disc ll, then discs 7 and ultimately the ratchet discs fixed to the ends of the reeler-bar, if there are such end discs provided, the fabric may be uniformly stretched all over its breadth.
If necessary, also shaft 9 may be hollow and a third shaft of still greater length may extend through it into the roller and carry a sleeve or the like iixed thereto.
The sleeves7 ratchet discs and so on may be replaced by other parts acting in a similar manner without departing from the spirit ofimy invention.
I claim:
l. In a device of the kind described in combination, a reeler-bar and means adapted to act only on the middle portion of said reeler-bar for fixing it in any desired angular position.
2. In a device of the kind described in combination, a reeler-bar, means on the ends of said reeler-bar and means adapted to act only on the middle portion of said reelerbar for fixing it in any desired angular position.
3. In a device of the kind ldescribed in combination, a hollow reeler-bar, a shaft extending into said roller, a rigid connection between the inner end of said shaft and the inner Wall of said reeler-bar and means on the outer end of said shaft for fixing it in any desired angular position.
4. In a device of the kind described in combination, a. hollow reeler-bar, a hollow shaft extending into said reeler-bar, another shaft of greater length extending through said hollow shaft into said reelerbar, rigid connection between the inner end ofV each shaft and the inner wall of said reeler-bar and means on the outer end of eachshaft for iixing it in any desired angular position.
5. In a device of the kind described in combination, a hollow reeler-bar, means on the ends of said reeler-b`ar for fixing it in any desired angular position, a shaft extending into said reeler-bar, a rigid connection between the inner end of said shaft and the inner Wall of said reeler-bar and means on the outer end of said shaft for fixing it in any desired angular position.
6. In a device of the kind described in combination, a hollow reeler-bar, a shaft extending` into said reeler-bar, a rigid connection between the inner end of said shaft and the inner wall of said reeler-bar, means on the outer end of said shaft for fixing it in any desired angular position and a bearing intermediate the end of said reelerbar and the inner end of said shaft.
In testimony whereof I aflix my signature.
