UNITED STATES PAT ENT OFFICE DRIVE FOR PLATING CARRIERS IN KNITTING MACHINES Ubaldo Pianta, Milan, Italy, assignor to firm Societa Italiana Ernesto Breda Per Costruzioni Meccaniche, Milan, Italy Application December31, 194?, Serial No. 794,837 In Italy December 31, 1946 1 Claim. (Cl. 66-129) The device according to this invention is intended to drive the displacement of the plating carriers, which are employed for reinforcing the heels of stockings and like hosiery goods, on ordinary knitting machines, in particular of the Cotton type.
Said displacement is now obtained, on the already known looms of the abovestated type, by means of braking devices, by which the carrier is stopped at the end of its travel, or by means of other more or less complicated devices.
According to this invention, a device has been designed, by which same purpose is attained through diiferent means, with the aim to obtain a remarkably simple structure and a working accuracy higher than that obtained on the machines heretofore employed, together with a possibly higher working speed, without mechanical troubles and without interfering with the good knitting action.
In the device according to this invention, the carrier rods are driven by a reciprocating gear, comprising at least one member which is moved transversely with respect to said rods, due to a reaction against inclined surfaces, which do not partake in said motion, so as to allow said member to engage with or disengage from the carrier rods.
In the accompanying drawing is diagrammatically shown, only by way of a not restrictive example, an embodiment form of the device according to this invention. In same drawing:
Fig. 1 is a front view of the device.
Fig. 2 is a plan view of same device.
Fig. 3 is a section along two perpendicular planes of the displacement driving gear.
On the drawing, 1 and 2 are the plating carriers, with the corresponding rods 4 and 3. On said rods are respectively secured the toothed pieces 5 and 6 which, as it can be noticed from the drawing, are provided with three teeth I, 8 and 9 and a fourth longer tooth Ill.
Said pieces 5 and 6 are set in motion by the member It, provided with a sliding piece I2, which can be locked in three pro-established positions by means of the little ball l3 which, under the action of a spring [4, engages into one of the recesses i5, machined on the piece I2; this latter piece shows a projecting tail I6, which engages, according to its position, with the teeth 1, 8, 9, l0.
Said piece I2 is firmly secured to the shaft of the roller I! which, during its travel, engages with the inclined surfaces l8 and [9 of the guides 28 and 2|, and with the inclined surfaces 22 and 23 machined on the pieces 24 and 25, in consequence of which the device in question operates in the following manner: In the position shown by the drawing, the piece II is moved from right to left; the roller H has been lifted from the surface l8, and consequently the tail It has been disengaged by the tooth 9 of the piece 5, which is kept still in the position shown by the drawing; together with this latter piece the rod 3 and the carrier I are kept still.
During the further motion of the piece It, the tail It comes upon the tooth ill of the piece 6, which is therefore brought to the left together with the rod 4 and the carrier 2, until the tooth l, engaging the retractable point 26 of the piece 25, after having elastically lifted same point, is stopped against the stop 27.
In the meantime the roller IT, by coming upon the surface 23, is brought down, causing the tail It to fall between the teeth 9 and If! of the piece 6, which in such a manner is brought to the right together with the rod l and the carrier 2, while the piece II is travelling back to the right. During said back travel, the roller ll meets the surface lil, by which it is lifted, While the tail [6 is disengaged from the piece 6, on account of which the piece 5 performs then the aforedescribed motion in a wholly symmetrical manner.
As it will be noticed from Figs. 1 and 3, the piece I2 is provided with two bosses 28, which allow to displace same piece even by hand, bringing it, when desired. in a third even higher position, so as to bring it out of action of the tail [6, thus bringing the plating carrier out of action.
The tooth l of the piece 5 and the tooth 8 of the piece 6 do not perform any work, and are foreseen with the only purpose to make the pieces 5 and 6 alike whereby they can be manufactured more cheaply.
It will be understood that the constructional details of the device according to this invention, have been shown in a wholly diagrammatical manner and only by way of example, on account of which many variants and practical means, well known to all experts of the art, are to be considered as embraced within the scope of this invention.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:
A device for driving the plating carriers in straight bar knitting machines, comprising in combination a piece reciprocating parallel to carrier rods of such machine, which move longitudinally forwardly and backwardly, said piece bearing a member displaceable transversely to said UNITED STATES PATENTS carrier rods, pieces not partaking in the movement of the carrier rods and provided with ing Z gl' clined surfaces engaging said transversely dis- 1877262 z 131932 placeable member, pieces fixed on the carrier rods 5 1912257 Comb 301933 provided with teeth of different heights engaging 2036804 Grossef Apr 1936 said transversely displaceable member for a de- 2171967 Anke 1939 tel-mined transversal position of the latter, 2367972 Start 'g Jan 1945 whereby said carrier rods are dragged by said I reciprocating piece for strokes determined by the 10 ORE GN PATENTS position of said inclined surfaces.
