- Specification of Letters Patent.` Y Patntd Rigby 1S s 1915 j Application ined July io, 1914. 'serial No.4s5aos5.

To all whom it 'may concern Be itl known that I, FREDERICK W. PEN- nnneasnpa' citizen'of the United' States, and resident of Cambridge, in the kcounty of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Brooms, of which the following is This invention vide' a strong and durable broom of simple and relatively inexpensive construction, and adapted to be manufactured by blind workmen. Y

The invention consists in the improved construction 'which I will now proceed to describe and'claim.

Of the accompanying drawings forming a part of this specification: Figure 1 rep'- resents a side elevation,partly in section, of my. improved broom;r Fig. v2 represents a section on line 2-2 of Fig.j1; Fig. 8 represents a sectional view illustrating apart of the operation of assembling the parts,

Fig. 4 represents a perspective view of one of the bunches ofbroom filaments hereinafter referred to;v Fig.k 5 represents a section on line 5-5 of Fig.j1`. i

The same reference characters indicateV the same or similar parts in all the views.

In the drawings, 12 represents the broom head, which is preferably a strip or block of wood having in one side a groove 13 ex-r tending lengthwise of the head, the outer ends of the groove forming shoulders orv abutments 14. y l y yIn the ends of the groove 13 are placed the inner ends of twobunches 15 of flexible broom filaments, which may beelongated strips of rattanV or othermaterial commonly used in the manufacture ofy brooms, each bunch being preferably formed by assembling a group of filaments and folding the same centrally to form a neck vportion 15a, which is reinforced and confined by a wrapping 15b of cord or string. 'Ihe neck portions are pressed closely against the rshoulders 14 and confined independently by suitable means such as nails 16 driven through the said neck portions and through the portions of the head which form the sides of the groove 13. Said rneck portions may be additionally secured by glue if desired.

18 representsa key, preferably of wood, formed to enter the groove'l?) between the bunches 15, the ends of the key forming shoulders 19 which bear closely against the has for its object to pro-` `necliportions 15a, said portions beingcompressed,:betweenf the

shoulders

14 and 19.

Before'u inserting the key in the groove a layer20 of broom laments is placed on the head with the filaments extending across the groove 13, as shown by Fig. 3,

.and the key 18 is placed on said layer. The cross sectional area of the key is considerably less than that of the groove, as shown by Figs. 2 and 3. The key and portions of the layer 20 are next forced into `the groove `13, the central portions of the laments being thus bent and conformed to thek back n and two sides of the key and the end portions of said filaments being caused to project from the head, as shown by Figs. 1 and 2. The key 18 and the filament portions confined thereby are now secured` to the head by nails 21, and if desired they may be vadditionally secured by glue.

l The central portiony of the head 12 may be provided with a socket to receive a handle 22. n Y

y The bunches 15 bear on the opposite edges of the layer 20 and cover the ends of the V-shaped space adjacent to the key 18 between the outwardly extending portionsl of said layer, so that there are no openings at the ends of the broom for the admission of dust. and dirt, the bunches 15 forming substantial additions to the brush materialv formed ,by the layer 20. The neck portions ofthe bunches 15 are conned not only by the nails 16 and the glue which may be employed, but alsoby the ends of the key, the length of the keyk being such that the operation of inserting it into the groove causes the ends ofthe key to exert clamping pressure Von the neck' portions 15a.y

Having described my invention, I claim: V1. A broomcomprising a head having a longitudinal groove in one side, a key filaments secured in opposite ends of the,` groove and bearingon the edges of said layer, said bunches covering the ends of the spaces adjacent to the key between the outwardly extending portions of said layer. i

2. A broom comprising ahead having a longitudinal groove in one slde, bunches of v brush filaments inserted and 'independently I' 'said key and bent outwardly acrossopposte e endsV bear on the bunches :1ndA press the saine eganst the ends of the groove, and a layer'of the `l1a1n `entsy engagedytherewith*bel'lg infastened in the end portions of seid grooveV dependently secured. in the groove.
