UNITED STATES BERNHARD I-IAGEMANN, `OF LAN(EiffelNHBS'J,` NEAR OGH'IRUP, GERMANY.
LICKER-N DEVECE FOR CARDENG ENGINES.
Application led April 29, 1925.
To all whom it may 00010671111,
Be it known that I, BERNHARD HAGEMANN, a citizen of Germany, residing at Langenhorst, nea-r Qchtrup, Province of Test-falen, State of Prussia, Germany, have invented certain new and useful Improvements in Licker-In Devices for Carding Engines; and I do hereby `declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the saine.
rlhis invention relates to licker-in devices for carding engines of the kind used for preparing cotton fibres for spinning and it has for its object to provide a licker-in device by means of which all fibres useful for spinning are delivered to the main cylinder of the carding engine, with the waste so effectively separated by the licker-in that substantially all fibers are delivered to the carding machine.
This object is atta-ined according tol 'the invention by arranging ahead of the licker-in grate at least one knife and by constructing the said grate and more particularly the grate portion lying nearest the said knife in such a manner as to cause the draught of air set up by the licker-in cylinder to enter almost exclusively the space existing between the cylinder and the grate.
An embodiment of the subject-matter of the invention is illustrated in the accompanying drawing which shows a transverse section through the licker-in device and the neighbouring` parts of the main cylinder of the carding engine arranged in succession thereto.
The licker-in device comprises, in a manner known per se, a cylinder A rotatable around a horizontal axis and provided on its .shell surface with saw teeth al. The cylinder A is adapted to be rotated by a mechal nism, not shown, at a speed of about 400 revolutions per minute. B is a table designed to feed the cotton fleece C to be treated. This table has its head face b1 arranged in close proximity to the saw teeth of the cylinder A and carries a roller D which, when the device is working, delivers the cotton fieece C into the teeth al of the cylinder A. The space between the face b1 of the table B and the saw teeth a1 is so small that the cotton grasped by the teeth al of the cylinder A in moving past the said head Serial No. 26,779.
face b1 is combed. Arranged below the table is an interchangeable knife E which serves to break and crush impurities contained in the fibres. The knife E has the cross-section of an isosceles triangle and is arranged so that one of its equal sides, el, is tangential or approximately tangential with relation to the cylinder A. The lower portion of the cylinder A is enveloped by a grate F the bars f1 and 7"'2 of which extend parallelly to the axis of thecylinder A. The grate F comprises two portions of different construction, one portion mainly serving as a fibre catching grate and the other as a cleaning grate. The fibre catching grate lies adjacent to the knife E and consists of a special catching bar f3 and four bevelled grate bars f1 which have a comparatively large distance from each other as well as from the teeth al of the cylinder A. The cleaning grate arranged in immediate succession to the catching grate includes a plurality of grate bars f2 which have from each other and from the teeth al of the cylinder A a considerably smaller distance than the bars f1, so that this portion of the grate is in effect a screen.
Mounted in succession to the described licker-in is the main cylinder G of a carding engine the card clothing g1 of which takes up for further treatment the cotton fibres cleaned by the licker-in.
The operation of the device is as follow-s:
The licker-in cylinder A, the feeding roller D and the main cylinder Gr of the carding engine are rotated and the cotton fleece C lying on the feed table B is inserted beneath the roller D. The cotton fed by the roller l) to the cylinder A is grasped by the saw teeth al and combed at the head face b1 of the table B. The combed fibres are then fed to the knife E which breaks and separates from the fibres the impurities contained therein. The draught of air set up by the rapidly rotating cylinder A is guided by the face e1 of thc knife E in such a manner that it flows into the space between the cylinder A and the fibre catching grate bars f1 so that all cotton bres carried along by the draught are securely fed to the fibre catching grate. The fibres flying onto the catching bar f3 and the grate bars f1 are carried on by the said draught of air which flows towards the cleaning grate f2, and after having been partly freed from impurities in passing over the fibre catching grate they enter the space` between the cylinder and the cleaning grate bars f2 Where further impurities yare separated from the fibres. As soon as the cotton libres have been carried beyond the cleaning grate' they are taken up for further treatment by the card clothing g1 of the main cylinder G of the carding engine.
The arrangement of at least one knife E which directs tl1e ,draught of air set up by the licker-in cylinder Alintothe space between the cylin-der and the grate, produces the advantage that losses of usefulcotton fibres such as are unavoidable in the Wellknown licker-in devices, can-no longer occur. Those fibres which a-fter passing the knife E are` not grasped by the saw teeth al and therefore have atendency to drop between the knife E and the catching bar 773 of the fibre catching grate, arev likewise carried on by the draught of air tothe fibre catching grate bars fl-and further tothe cleaning girate bars f2.5- -esides, the provision of a somewhat enlarged space betiveen the rods f1 of the fibre catching grate and the lickerin cylinder A and the arrangement of a special catching-bar f5 at the front'edge of the fibre catching grate considerably facilitate the introduction of the draught of air into the cleaning grate.
- f Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is
l. A lieker-in device for carding engines, comprising feeders, a rotary licker-in cylinder, and a separating member arranged beneath the cylinder and providing in part a grate and in part a screen, a knife arranged ahead of the separating member with that .face next the cylinder approximately tangential to such cylinder, the grate portion of the separating member having a liber catchingvbar adjacent the knife and being spaced farther from the cylinder than the screen portion of the separating member, the latter being substantially concentric n'itb the cylinder.
2. A licker-in device for carding engines, comprising a feeder, a vrotary licker-in cylinder, a separating member' arrangedl below the cylinder, and a knife interposed between the feeder and entrant end of the separatine' member, said knife having a face arranged substantially tangential to the cylinder, the entrant end of the separating device being spaced farther from the cylinder than the knife face,^\vhereby the air current set up by the cylinder is guided by the knife into the space` between the separating member and cylinder.
In testimony whereof I have signed my name to this specification.
BERNHARD HAGEMANN.
