This invention relates to certain improvements in or relating to warp tying or knotting machines.
l'n warp knotting machines, pairs of brushes or needles (s0-called clips) or mixed groups of brushes and needles are required for dofng or taking off the thread at the top and at the bottom, according as the threads to be knotted are parallelly disposed or crossed. Since in a textile factory a plurality of such take-Gif mechanisms are occurring, the hitherto known knotting machines have been designed in such a way that their thread doing means are variable for each of these four different kinds of doiiing; to this end, especially the needles and brushes are interchangeable. This interchanging, however, is difcult, since the connecting screws to be removed are of poor accessibility, the screws may be lost and require special tools by the handling of which the sensitive parts of the machine may be damaged. Primarily, however, the correct and true adjustment of these parts after their re-fitting is not ensured, so that the machine in many instances after the exchange does not operate satisfactorily.
In order to eliminate these difficulties, a separate non-variable knotting machine has been developed for each of the four thread doing mechanisms occurring, which four knotting machines may operate on the same warp tension device. This, however, requires a larger number of these relatively expensive warp tying machines, whose capacity can hardly ever be utilized fully.
It is an object of the present invention to provide a solution of the problem which avoids the drawbacks of the two known types of machines while combining their advantages.
With this and further objects in view according to the present invention the drive for the movement of the machine over the two warp tension devices and for the changing of the movable carriage of the warp tension device as well as for the control and driving instrumentalities of the real thread guiding mechanism are arranged in a universal frame which is common for all thread doll-lng mechanisms and into which the thread guiding mechanism which is combined into a block, can be inserted so as to be easily interchangeable. Thus all material parts which remain unchanged, such as the drive for the travel of the knotting machine over the two warp e On the other hand, the thread guide mechanism, comprising the feeler, the thread doing mechanism and the thread guide, is manufactured in four different types corresponding to the four different doing methods and can be interchanged in the main frame by a simple manipulation without requiring skilled labor. The satisfactory operation of the machine remains ensured. To this end, it is merely necessary to adjust a mark on the main frame deiining the angular position of the control shaft and a corresponding mark on the block dening the angular position of the driving gear of the thread guide mechanism.
The total cost of such a machine with four interchangeable blocks embodying the diiferent take-01T mechanisms is substantially less than that of four complete machines. A further advantage consists in that the assemblage of the parts combined in the block, i. e., the thread feeler, the thread take-olf mechanism and the thread guide is substantially facilitated compared to the assemblage in a complete universal machine. This is further facilitated by constructing the block in the form of a hollow case accommodating the thread feeler mechanism and at one of its outer sides the thread take-olf and thread feeding mechanisms; in this case, a substantial part of the mechanisms is freely accessible.
It will be understood that my novel machine also offers substantial advantages as regards the cleaning.
Other and further objects, features and advantages of the invention will be pointed out hereinafter and appear in the appended claims forming part of the application;
In the accompanying drawings a preferred embodiment of the invention is shown by way of illustration and not by way of limitation.
Fig. 1 is a perspective front View, from the bottom right hand side, of the common standard or universal main frame,
Fig. 2 is a perspective rear View, from the top left hand side of the block unit of a thread guide mechanism, on a larger scale.
The main frame 2 which is U-shaped and provided with bars l accommodates an electric motor (not visible)A including a gear, and a hand drive, both driving the main shaft 4 through a chain 3. Mounted on the main shaft 4 is the driving pinion 5 and two eccentrcs for the rocking arms E and l. Moreover the driving shaft is operatively connected, through worms and pawls, to the toothed wheel 8 for the feed through the two Warp tension devices and to the toothed wheel 9 for 3 the changing of the movable warp tensioning carriage. Furthermore, the main frame 2 bears the thread gripper IIJ and the knotter II. A guide I 2 serves for the reception of the interchangeable block I3.wh'ich bears bylits recess FHI-,on thesupport I5 Varranged iin the main frameand bythe face I6 of the bar I'I on the bridge I8 arranged` in the main frame; said bridge being formed with a slot I9 in which is engaged the threadedv bolt of the bar I'I which is locked by swinging the bar I'I protruding throughva slot :"ZI yofit'h'e front shield 22 of the block.
