1 My invention which relates generally to warp knitting machines, particularly has reference t the means for racking the thread guides of such machines.
MOF@ SDeCiflCallY it is an ObJ'eCt 0f my present 5 attached to it at one end. The back racking bar invention to improve the racking means used on also has a similar tting |08 at the correspondtricot machines and to that end the thread guide ing end. Mounted, one above the other, in the bars are actuated in-their racking movement by brackets are shafts |09, ||0, the shaft ||0 a pattern wheel or cam and a racking lever so being the master pattern wheel shaft, and the as to move the guide bar in one direction while shaft |00 being a shaft on which the racking leve another pattern wheel or cam moves the same bar in the other direction, one pattern wheel or cam acting as a counter or follower for the other pattern wheel or cam, the acting cam being supported, in addition to its counter, by spring pressure. The connections between the racking lever and the guide bar are so arranged that there is a direct contact between the two so that when the bar is moved in one direction it is pushed and held in position by its counter connection and in the reverse direction it is pulled and held in position by its pushing support.
Other objects of the invention will in part be obvious and in part be pointed out hereinafter.
To the attainment of the aforesaid object and ends the invention still further resides in the novelA details of construction, combination and arrangement of parts, all of which will be first fully described in the following detailed description, and then be particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which:
Fig. 1 is a front elevation of a portion of a warp-knitting machine embodying my invention.
Fig. 2 is an end elevation of the same on a reduced scale.
Fig. 3 is a detail section on the line 3-3 of Fig. 2.
Fig. 4 is a detail section on the line 4-4 of Fig. 2.
Fig. 5 is a detail section on line 5-5 of Fig. 3.
In the drawings in which like letters and numerals of reference indicate like parts in all the figures, I designates an end frame of the machine and 3 the longitudinal pipes that connect the end frames together.
Vertical longitudinally disposed brackets 5 are secured on the end frame I shown in Figs.
is swingably and reciprocatingly mounted is shown at I3 in Figs. 1 and 2.
Referring now to Figs. 1 and 2, it will be observed that the racking bar |00 has a fitting |01 ers ||9 and |20 are rockably mounted. The shafts ||0 and are geared together by spur gears ||2 and the shaft I0 is driven from cam shaft 6 through worm gears I3 and I4. ||5 indicates the master patterr wheel and I0 the follower pattern wheel which Contact, respectively, the rollers |3I and |32 on the yoke |29 of the lever H9. The rollers |33 and |34 on the yoke |30 of the lever |20, cooperate, respectively, with the master pattern Wheel ||1 and follower pattern wheel ||8 (Fig. 2) on the shaft H0. A longitudinally adjustable connecting rod |2| has one end pivoted at |22 to the lever ||9 and its other end pivoted at |23 to the fitting |01. A twopiece push rod |24 having a turnbuckle connection 2|3 has its ends of semi-spherical shape to lit corresponding sockets in the lever H9 and in the tting |01 (see dotted lines 2|5 in Fig. 3). By this construction any play which might take place between the lever I9 and the front thread guide frame can be taken up. A longitudinally adjustable connecting rod |25 is pivoted at one end, as at |20, to the lever |20 and at the other end, as at |21, to the fitting |08 of the back thread guide bar (Fig. 1). A two piece push rod |28, having a turnbuckle 2I4, has its semi-spherical ends set into corresponding sockets, (similar to the rod |24) in the lever |20 and the fitting The yokes |29 and |30 each carries two slide rods |38 having rollers |31 and springs |30 which constantly force the rollers into contact with take-up cams and |30, respectively.
Referring again to Figs. 3 and 4, it will be seen that the connecting or pull rod |2| is oset.4 The offset portion 2|9 is apertured as indicated by dotted lines 2 20 in Fig. 3, and the rod |24 passes through the aperture. f 'A v Power is applied by any well known or suitable means (not shown) to shaft 0 as a rst motion shaft of the machine.
From the foregoing description taken in 'connection with the accompanying drawings it will be seen that the racking movements take place by positive push pull actions, without the use of pull-back springs and is at all times free from lost motion or back lash, thus providing for uniform racking in both directions, and it is thought the construction, operation and advantages ol my invention will'be clear to those skilled in the art.
