4 Claims.

This invention relates to strumming device In long chain beaming, the warp in rope formis usually led from a source through tension rolls in a tension frame andthen is led a substantial distance to a beamer where it is spread out into a fiat sheet by passing through a suitable comb or reed and then wound onto a warp beam for further processing, such as for use in a loom for furnishing the warp to the loom and for other uses.

It very often happens that the warps are not properly separated and stick together, and by providing this strumming apparatus, the warps are strummed ver much in the same manner as in a stringed instrument, such as a banjo is strummed or played, so as to vibrate th warpthreads and separate them from each other.

It is an object of this invention to provide means in a long chain beaming apparatus or any type of apparatus wherein a warp sheet is placed onto a warp beam for vibrating the warp threads and shaking them apart from each other.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which Figure 1 is a top plan view of a portion of beaming apparatus;

Figure 2 is an elevation of Figure 1 looking from the lower side of Figure 1;

Figure 3 is an end elevation looking from the left-hand end of Figures 1 and 2;

Figure 4 is an enlarged detailed View taken along the lines 44 in Figure 1;

Figure 5 is an enlarged detailed view taken along the line 5-5 in Figure 1 and showing the warp threads which have been omitted in Figure 1 at this point.

Referring more specifically to the drawings, the numeral l indicates a portion of the frame of a beamer which .usually comprises uprights H and I2 having certain geared mechanism therein and, of course, the other end of the beam is suita'bly supported as only one side of the warper is shown. In this conventional beaming apparatus, there is a shaft M which has thereon a pinion l which is driven by any suitable means not shown.

Pinion l5 meshes with a pinion I6 mounted on a shaft l1 and also mounted on shaft I1 is a pinion 20, which pinion meshes with a pinion 2| having integral therewith a beveled gear portion 22 which meshes with a beveled gear 23, mounted on a shaft 24, which is suitably mounted in a bracket 25, and upper end of this shaft has an arm 26 mountedthereon provided with a pin 21 which is adapted to have movement in a slot 28 in n arm 29, pivoted as at 39 on an angle bar 3| projecting from a rectangular frame which comprises not only the angle bar 3| but another bar 32 and end bars 33, only one of which is shown, there being another one at the other end of the frame. The rectangular frame comprising angle bars 3|, 32 and 33, is supported by vertically disposed legs 34, having two of these legs at each end of the frame but only two of which re shown in the drawing.

Pivotally mounted intermediate their ends as at 35 on bar 3| is a pluralit of members 36, each of which has integral with one end, or each end thereof a T-shaped portion 31 which has upwardly projecting ends for receiving a bolt 38, which penetrates a hole in a member 40 to secure these members 40 in position. These members 40 are very thin and resilient and are such as is employed in a conventional electrical dropwire stop motion.

Pivotally secured, as at 42, to each of the members 36, is a bar 44 which is pivotally connected as at 45 to the end nearest the observer in Figures 1 and 2 of the lever 29.

The warp 4|, before passing through a comb or reed 39, passes over these members 36 and the strumming members 40 and is wound onto a conventional warp beam- 41 which is rotated in a conventional manner by the beamer.

It might be added that th invention which is mounted on the rectangular frame, comprising

members

3 I, 32 and 33 and legs 34, is not attached to the beam-er by any means except by the pin 21 engaging the slot 28 of the lever 29. The legs 34 support the strumming mechanism and it is slid into position beneath the sheet of warp 48 and may be anchored to the floor by any suitable means not shown, though its Weight would hold it in position.

In order to prevent the warp threads 4| from falling down onto the strumming members 40, there is provided a pair of arms 49 which are secured at one end to the bar 3|, only one of the bars 49 being shown, and these bars support a rod 50 a substantial distance above the bars 3| and 32, as well as the oscillating bar 44 because these bars might have rough edges thereon which would engage and hold the yarn and cause a breakage of some strands of yarn if the sheet .of warp should be allowed to contact these rough bars.

It is thus seen that I have provided a, simple framework having strumming means associated therewith which can be quickly placed in association with a beamer and which will strum the warp threads from the lower side and will not in any way interfere with the operation of the beamer, and which can be easily removed to gain access to any portion of the beamer.

In the drawings and specification, there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being defined in the claims.

I claim:

1. Apparatus for strumming a sheet of Warp as it travels to a warp beam in a beamer comprising a framework disposed below the sheet of warp, and having a plurality of members mounted for pivotal movement intermediate their ends, and having at each end thereof upwardly projecting resilient fingers for penetrating the warp, means driven by the beamer for imparting oscillatory movement to said members in a horizontal plane to progressively engage various ones of the warp threads for imparting a strumming action thereto.

2. In strumming apparatus adapted to be associated with the beamer, a framework disposed adjacent the beamer and below a sheet of warp traveling to the beamer, a plurality of members pivotally mounted therein on the frame and below the Warp and having uprising fingers at each end thereof, means driven by the beamer and pivotally connected to said members for oscillating said members to move said fingers transversally of the warp for strumming the warp.

3. Apparatus for strumming a sheet of warp as it travels to a warp beam in a beamer comprising a framework disposed below the sheet of warp, and having a plurality of members mounted for pivotal movement intermediate their ends, and having on at least one end thereof upwardly projecting resilient fingers for penetrating the warp, means driven by the beamer for imparting oscillatory movement to said members in a horizontal plane to progressively engage various ones of the warp threads for imparting a strumming action thereto.
