Addition to patent 225001 from July 14, 1908. *)

Patented in the German Empire on April 4, 1909. Longest duration: July 13, 1923.

The invention relates to a further embodiment of the gear change transmission with step gears and a change gear seated on an inclined shaft, displaceable between the steps according to patent 225001 and has a Device for influencing the axially to the step wheels and perpendicular to their common Central plane shiftable change gear shaft to the object.

With the establishment of the patent 225001 now the disadvantage asserts that the Lever for influencing the vertically displaceable bearing journals for the change gear shaft sit on an axis of rotation, which is parallel to the change gear shaft, but crooked are stored on the countershafts.

The storage parallel to the change gear shaft, but skewed to the countershafts the axis carrying the attack lever makes the vertical displacement of the change gear a relatively complicated and cumbersome lever combination required, which, due to their greater space requirements, the overall length of the intermediate gear considerably enlarged.

Therefore, according to the present invention, to remedy the disadvantages mentioned the axis carrying the attack lever is parallel despite the inclined mounting of the change gear shaft stored on the countershafts, which is achieved in that the vertically displaceable Bearing journals of the change gear shaft connected to the attack lever by articulated pieces are, which are offset against each other in the direction that the points of attack the levers influencing them of the same arm length and their common axis of rotation lie in a straight line parallel to the countershafts.

An embodiment of the device according to this invention is shown in FIG and FIG. 2 illustrates a front and side view of a floor mat.

The change gear h, which in the position shown is in engagement with the step gears d, e , is rotatably attached to the shaft α, α, which is mounted parallel to the generator of the two step gears, as in the main patent by means of an obliquely drilled bushing. The latter is guided in a slot r in the hollow bearing arms in which the two vertically mounted guide pins q, q ¹ , on which the change gear h rests, are slidably arranged. The adjustment of the wheel h takes place by means of the shaft% from the wheel i through the toothed gear a ¹ , b.

The two vertically displaceable bearing journals q, q ¹ are now with the influence

Claims (1)

the levers c, c ¹ , which are wedged at both ends of the axis η , connected by hinge pieces q ^s , which are angled in the direction against each other so (Fig. 2) that the points of application q * of the lever c, c ¹ in a straight lines parallel to the countershafts. Because the attack levers c, c ^{1 are} of the same length, the axis of rotation η carrying them and supported on the bearing arm m extends ίο also parallel to the countershafts or perpendicular to the image plane according to FIG. 2. The lever arm g is also attached to the shaft η , the free end of which is connected to the pulling element fi guided over the roller 0 , the handle of which is easily accessible to the operator of the machine. Godfather ν τ-Α ν saying: Gear change gearbox with step wheels and a change wheel seated on an inclined shaft and displaceable between the steps according to patent 225001, characterized in that the vertically displaceable bearing journals (q, q ¹ ) for the change gear shaft α with the levers influencing them / c, c ^l ) are connected by joint pieces (q ^z ), which are offset in the direction against each other so that the points of application (q ^z j of the levers (c, C ¹ J of the same arm length and their common axis of rotation (n) are arranged parallel to the countershafts. 1 sheet of drawings.
