IGNAZ ETRIGH,

OF OBERALTSTADT, NEAR TRAUTENAU, BOHEMIA.

HECKLING-MACHINE Application `filed November i8, 1919.

To allee/wm t maf/l concern.'

Be it known that I, IGNAZ Eamon, a subject of the @Zeche-Slovak Republic, residing at Oberaltstadt, near Trautenau, Bohemia, have invented certain new and `useful Improvements in Heckling-lllachines; and l do hereby vdeclare the .following to be a full, clear, andexaet description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

lThis invention relates to a heckling apparatus for dividing and thoroughly cleaning ofiiax, hemp or similar fibers from the bast .of plants for making them ready for further treatment on cai-ding machines.

rllhe essenceV of my invention consists in that the fibrous material to be treated is fed forward by means of an apron provided with short pins and that above the apron heckle .needles are arranged which extend between the pins on the apron and rapidly oscillate in planes at right angles to the plane .of the apron and inthe direction .ot the movement thereof; the heckle needles are adjustable in a direction normal to 'the apron and the inclination et the center line of the oscillations of the needles to the plane of the apron is likewise adjustable.

The present heckling apparatus is suitable for any swingled or seutched bast fibers and is preferably directly attached to the swinn'ling or sent-ching apparatus so that the material is delivered from the latter immediately into the present heckling,` apparatus.

In the annexed drawings Figure 1 is a side elevation of a scutching and cleaning apparatus,

Fig. 2 is a plan view of the same;

Fig., 3 is a side elevation, partly in section, of the improvement; and

Fig. a is a plan view of the same, with parts omitted.

rllhe apparatus shown in Figs. l and Q tor scutching and cleaningl forms the subject mattei' of an application Serial No. 338,931, bearing even date with the prese it one and I shall describe here only so much ot' it as is necessary for the understanding' ot' the present invention.

The raw material (such as flax, straw, short flax or the like) is supplied to a series of fluted breaking rollers l which delivers the broken raw material in the form of a compressed coherent layer to a scutching apparatus consisting` of two drums 2, 3 hav- Specification of Letters'latent.

ing parallel aziesand carrying radial scutehing blades 4,5, the circumferential velocity olf which is considerably greaterthanthat of the breztkingg` rollers l', (i, 7 are strippingr rollers revolving inthe saine direction as the scutching drums and having a circu1nierential velocity smaller than that oi? the scutching` blades, but .greater than that et' the following series of breaking` rollers 1l; to the latter the material coming from the scutching drums 2, 3 is delivered being loosened or so to speakjumped up. ln the se ries or' 'breaking rolls ll-.the nnterial is again compressed and is then delivered to another soutching apparatus El, 3l, el, l provided with stripping drums (il, ,T1 and further passes Athrough a third series ot breaking rollers l2 and a third scutching apparatus 22, 32, 42, 52 ot which only the upper scutching drum 22 is provided with a stripping `drum G2. From the last named seutching apparatus the material is delivered in the form of a coherent somewhat loosened fleece like layer to the presenthecklinn apparatus. This consists of an apron 101 composed of rots and provided with pins 100; above this apron strong' heckling needles 102 are mounted on vtransverse shafts 103. the pins on the apron and rapidly oscillate in vertical planes in the direction of the movementv .of the apron, the points of the hec-kling' needles entering into the fleecy. material between the pins 100. The heck ling; needles are adjustable in a direction at right angles to the plane of the apron for adjusting the depth to which they enter into the material. Further the center line oithe oscillations (and if desired also their amplitude) of the heckling needles may be adjusted in any suitable manner. The inaterial delivered to the apron 101 in the form of a loosened fleece l s already stated is held and fed forward by the pins 100 while the strong heekling needles owing to their rapid oscillations divide or heckle the material, all the shive still adhering to the fibers being stripped off and shaken out falling down between the rods of the apron.

Of course the heckling needles are arranged in rows parallel to the direction ot movement of the apron, a number of such needles correspending to the width of the fleece being mounted on a common transverse shaft 103, to which a rapid rocking movement is imparted by means of cams These needles extend between f chine and spun. The material thus running in oil or in any suitable manner. Preferably the heckling needlesof neighboring transverse shafts are staggered.

I am aware that it has been proposed to treat tow and similar materials by the co'- operation of a reciprocating grid provided with pins projecting therefrom and needles koscillating above theV grid butnot extending between the pins. This known arrangement is not included in my invention;

. The material delivered from the apron is of a purity not obtainable in any other manner, it is free from knots and ielted parts, it shows a smooth well divided fiber which can be immediately brought Ainto a carding macleaned is suitable for spinning tow yarns up to the inest numbers.

Theapparatus requires only little attendance by unskilled laborers, is of high eiii- 'ciency and shows a great output in good fiber.

Claims:

l. A' heckling apparatus comprising 'in combination with an open means for moving the same continuously in one direction, pins on such apron, adapted to engage with a layer of fibrous material to be heckled, heckling needles mounted above the said apron, the downwardly directed points of the heckling needles extending between the pins 'of the apron and being adapted to engage with the material to be heckled, and means for oscillating the heckling needle points inplanes at right angles to and in the direction of the movement of the layer of fibrous material to be heckled.

2. A heckling apparatus comprising in combination with an open means for moving the same continuously in one direction, pins on such apron, adapted to engage :with a "layer of librous material to be heckled, heckling needles mounted above the said apron the downwardly directedpoints'oi the hecklingV needles extending between Vthe pins of Y he apron and being adapted to engage with the material to be heckled, and Vmeans for oscillating the heckling needle points in planes 4at rightangles to,V and in the direction of the movement of the layer oi fibrous material to be heckled and means Vfor adjusting the heckling needles in a. direction at 4right angies to the plane of the layer of material toabeheckled whereby vthe -de'pth'to whichthe points of the heckling needles en'- ter suchmaterial may beadjusted.
