MECHANICAL MOVILIVIENT FOE STRAIGHT HOSIERY FRAMES.
Application filed March 5, 1924. Serial No. 697,138.
To all whom it may concern:
Be it known that I, WOLDEMAR Hmnrrz, a citizen of the German Republic, and resident of Chemnitz, Saxony, Germany, have invented a new and useful Improved Mechanical Movement for Straight Hosiery Frames, of which the following is a specification.
This invention relates to a mechanical movement for use in connection with straight hosiery frames; more especially, it relates to a driving gear for the thread guide bar of such frames. WVhile hitherto the bar transmitting motion from the lmown eccentric disk to the known thread guide bar has been reciprocated by the intermediary of a set of levers which rendered the service uncertain by reason of the elastlcity of the levers, I employ a rotary gearing as transmission means. The drawbacks resulting from the elasticity of the levers become particularly detrimental, if the hosiery frame is pretty long and when lts worklng speed is increased. Both these circumstances are of no consequence where my improved transmission gearing is used. 7
My invention is illustrated by way of example in the accompanying drawing which shows a front view of the gearing in question, the known thread guide bar and the known means for rotating the eccentric disk being omitted,
a is the eccentric disk which is rotated by the shaft 'a Behind the disk (4 is a reciprocating bar 6 which is guided by and between the guide members 6. The bar I) is provided with two rolls 0, of which one is located on one side of the disk a and the other on the other side thereof, so that it is reciprocated by the disk when this is retated.
A portion d of the bar a is toothed so as to form a rack. This rack meshes with a pinion g which is firmly connected with a this rack Z meshes with a pinion 7: supported on an axle 2' and meshing in its turn also with the cog-wheel 7L.
Supposing, the eccentric disk 64 rotates in the direction indicated by its arrow, the bar 5 will be shifted to the left, as indicated by its arrow, then back to the right, then again to the left, and so on. At the same time, the bar on will be reciprocated in,
just the same manner, the only difference be ing that its speed is a little higher than that of the bar Z) owing to the pinion is being a little smaller than the pinion g. I wish it, however, to be understood that the arrangement and combination of parts shown, as well as the dimensions thereof, for instance the diameters of the wheels forming the gearing is merely an example. The size of the pinions and of the cog-wheel may vary according to the requirement in a given case, also the number of the wheels constituting the gearing may vary. The ratio of the transmission may be chosen as desired or required. At any rate, the motion is transmitted from the bar 6 to the bar m without any elastic intermediary whereby Y the drawbacks hitherto experienced are perfectly obviated.
1. A mechanical movement for use in connection with straight hosiery frames and apt to serve as driving gear for the bar transmitting motion to the thread guide bar of the frame, comprising, in combina tion, an eccentric disk, means to rotate it; a shiftable bar, and means to transmit the revolutions thereof to said bar so as to reciprocate it; another shiftable bar arranged parallel to the first-mentioned one at some distance thereof; teeth at the opposite edges of said bars; a pinion meshing with the teeth of the first-mentioned bar, a cog-wheel firmly connected with said pinion, and another pinion meshing with said cog-wheel,
as well as with the teeth of said other bar,
for the purpose set forth.
