UNITED STATE RALIEI -I' THOMSON, OF SIOUX FALLS, SOUTH DAKOTA.

BROOM.

Application filed May 27, 1926. Serial No. 112,073.

This invention relates to improvements in brooms. 1

he primary object of this invention is the provision of an improved broom including a brush head or whisk port-ion formed of broom corn panicles held together in a novel fixed relation to mostefficiently reinforce the same at the side edges of the broom.

A further object of this invention is the provision of an'improved broom embodying a whisk of the conventional. form having a novel type of stitching transversely across the handle connected end thereof, in which the spacing of the stitches is closer at the side margins of the broom than at the intermediate portion of broom whisk portion, to

' most efiiciently reinforce and properly connect the broom with the stitching against liability of accidental and premature loosening.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part ofthis specification, and wherein similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevation of a broom of conventional shape, having the improved stitching formed as a part thereof.

Figure 2 is a side elevation of a broom in which the stitching is used as illustrated in Figure 1 of the drawings, although at both side marginal edges of the broom brush head.

Figure 8 is a somewhat diagrammatic rep-' resentation of the form that the sewing thread takes when the same is stitched about the brush head of the broom. v

In the drawing, wherein for the purpose of illustration are shown preferred and modified forms of this invention, the letters A and B may generally designate brooms of the corn whisk type including a brush head 0 having a handle D connected therewith, and respectively sewed by novel transverse rows of stitching E and F.

The brush head C of each of the forms of invention A and B consists of strands of' any approved nature, preferably conventional broom corn, assembled in the flat manner as is quite ordinary, and connected to the handle D by wire clamping means 10. Adjacent the handle end of the brush head C the rows of stitching E and F are placed. This stitching E and F, as the case may be, is preferably placed by means of an improved broom sewingmachine such as set forth in my co-pendingapplication, Serial No. 58,153, filed Sept. 23,1925, and the essential novelty of the invention consists in the placing of the transverse stitches in closer relation at the side margins of the broom brush head than the spacing of the intermediate .stitch'es- Inthe form of invention A illustratedinFigure 1, the spacing of the stitches in closest relation is effected only at the finishing side of the brush head, that is, the side of the brush head which is stitched last, whereas the form of invention B has the stitchings at both side margins of the brush head spaced close together, with the intermediate stitches spaced farther ap art.

While the sewing of the stitches may be effected in any approved manner, and the thread may be handled in any relation desired, it is preferred to use the stitchingillustrated in Figure 3 which consists in. securing the thread at 15 adjacent one side margin of the brush head and then threading the same at 16 transversely thru the thickness of the brush head 0, and then wrapping the same at 17 and 18 twice peripherally about the brush head, to a location adjacent the transverse thread 16, and at which place the needle of the broom sewing machine starts the transverse loop stitching as at 20, which is extended back and forth in a zig-zag relation, first beneath the two rows of threads at one side of the brush head, and then transversely thru the brush head and beneath and over the two rows of threads at the opposite side of the brush head C; the transverse stitching being somewhat diagonal as illustrated in t Figure 3 of the drawings. The transverse lines of stitching are regulated as to their spaced relation by the novel step-by-step regulating means set forth in my application above referred to, so that the transverse stitches 25 at the side marginal portions of the brush head are spaced closer together than the intermediate transverse lines of stitching 27 between theside marginal portions of the brush head C, as can readily be the closer spaced stitches 25 are only pro-- vided at the finishing side of the broom, in

in so far as the securing of the Whisks in the brush head are concerned, Which Will give durability and greater resiliency to the broom during use.

Various changes in the shape, size, and arrangement of parts may be made to the forms .of invention herein shown and described,

Without departing from the spirit of the invention or the scope of the claims.

I claim:

1. As an article of manufacture a broom including a brush head secured together by means of transverse stitching, the stitches of said transverse stitching being disposedappreciably closer together at the side edges of the broom than at the intermediate portion thereof. r

2. As an article of manufacture a floor broom including a conventionally shaped flat brush head formed of a plurality of pieces, and stitches transversely disposed across the conventionally the practice and closer than the stitches at the intermediate portion of said brush head.

3. As an article of manufacture a broom including a brush head formed of a plurality of pieces, a band substantially peripherally encompassing said brush head, and transverse stitching thru the brush head looped about said band, the stitching being formed to provide aplurality of closely spaced stitches at the side marginal portions of the brush head and farther apart spaced stitches at the intern'iediate portion of the broom.

4:. As an article of manufacture a broom including a brush formed of a plurality of pieces, a band substantially peripherally encompassing said pieces to hold them in place, and transverse stitching thru the brush head looped about said encompassing band, the transverse stitching including athread Which at the finishing edge of the brush head has the stitches thereof closer spaced together than elsewhere along the line of the encoinpassing band.
