CONSTRUCTION FOR BEAMS.

.Application filed'May 20, 1920. Serial-N0. 382,723.

To all 107mm it may concern.

Be it known that I, WVALTER I. TUTTLE, a

. citizen of the United States, and a resident This invention relates to warp beams and similar apparatus and deals more specifically with means for securing or anchoring the ends of warp threads and the like. One of.

the objects thereof is to provide simple and practical means of the above nature which shall be effective in action and convenient in use. Another object is to provide means of the above type which shall not only be.

thoroughly dependable but shall not tend to weaken or injure the material withwhich it is used. Other objects will be in part ob-.

vious and in part pointed out-hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the structure hereinafter described and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, in which are shown two or more of various possible embodiments of the several features of this invention,

Figure 1 is a plan of a portion of a beam barrel; 7

Figure 2 is a cross-section on the line 22 of Figure 1;

Figure 3 is a fragmentary plan of a beam barrel showing another embodiment of cer tain features of the invention; and

Figure 4 is a sectional view taken along the line 4-d of Figure 3.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring now to lligure 1 of the drawings, there is shown an intermediate, portion of the barrel of a warp beam, this barrel being provided with the usual heads at the end and being of hollow sheet metal construction as indicated by the detailed sectional view of Figure 2.

At intervals along the length of the barrel there are formed openings, two of which appear in Figure 1 of the drawings. These openings are cut through the metal preferably in substantially circular form as shown at 10 but leaving integral the oppositely directed tongues 11 and 12 extending in a circumferential direction. These tongues, as better shown in Figure 2 of the drawings, are slightly depressedas at 18 andtheir extremetips are so shaped as not to project beyond the general surface or contour of the barrel. I

Considering. the use, and action of this device, the threads, the ends of which itis desired to fix in position or anchor preparatory to w nding upon the beam,aregathered and knotted into a loop whlch is placed about either the. projectionv 11 or projection 12 in accordance with the direction in which it is desired to wind the warp. Another group of threads for example may be knotted to extend over another one of these pins 11 and 12 and so on throughout the width of the warp. The loop thus secured slips downwardly to the root portion of the pin and is firmly held in position. If desired the threads in question might be formed into a knot and this knot drawn into the angle 14 to anchor the ends of the thread, but although the device is susceptible of such use its preferable use is that above set forth in which it is securely held and cannot slip or cut through. This is'of especial advantage in the case of wind ing such material as rubber. Itis also to be noted as the pin or projection extends out substantially flush with the outer surface of the drum, there is ,no pronounced sharp corner or shoulder at 14k over which the thread is drawn with a tendency to injurethe same, The security of holding, by

the way, is enhanced by rounding the pins Referring to the construction shown in Figure 3 of the drawings, the barrel is likewise provided with a plurality of substantially aligned attaching devices, one of which shown in the drawings. In this case a circular opening 15 is cut through the sheet metal. and a pin 16 extending in the direction indicated in Figure l of the drawings, is secured preferably by spotwelding to the inner surface of the barrel at 17. This pin which is rounded on its sides and points and which is preferably enlarged as indicated at 18 to term a more secure attachment, has many of the advantageous features of action of the construction first described.

It will thus be seen that there is provided apparatus in which the several objects of this invention are achieved.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiments herein set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrated and not in a limiting sense.

I claim as my invention:

1. In securing means for beams, in combination, a hollow metal beam barrel provided at relatively spaced points along its length, with openings each of small size relative to its diameter extending through the barrel, and a projecting part extending in a general circumferential direction into each of said openings and substantially flush with the upper surface of the part from which it projects, each of said projecting parts being adapted to enter a loop of the part from which it projects and to i which it is permanently secured, said projecting part being adapted to enter a loop and being free from contacting parts on its lower surface whereby it tends to retain its normal position upon being inserted within a loop.

3. In securing means for beams, in combination, a hollow metal beam barrel having an opening therethrough of small size relative to the diameter of the barrel and having on opposite sides of said opening and directed toward. each other a pair of projecting parts, the free ends of which are spaced one from the other and the lower surfaces of which are free from contacting parts whereby said projecting parts may onter loops and maintain their normal position. i

In testimony whereof, I have signed my name to this specification this 17th day of January, 1920.

lVALTER I. TUTTLE.
