BROOM.,

Application filed september 6, 1924, Serial No. '736,30'5. ReneWed August 20, 1927.

My .invention relates to improvements in brooms, and particularly in hrooms having remorahle handles broom With remo able handle is advantageous for several reasens; one reason is that either the handle on the brush may be replaced When broken or 'Worn out, Without the necessity ot' discardng the Whole; another reason' is that the separated parts may he packed in quantity :for shipment with substantial economy of cost and of space.

A broom embodying my invention is illustrated in the acconipanying drawingsfi Fig. a View ot the broom in side elevation; F II is a. :tragmentary 'view to larger Scale, in medial Vertical section; Fig. III is a view in transrerse section, on the plane indicated by the line III-IIL Fig. II. Fgs. IV, V, and VI are Views in perspective of certain parts detached. The succession of these three figures on the sheet is in the order of assembly. i

The broom structure includes essentially the brush l, the handle 2, and the keeper 3. rddtionally a shield 4; is conveniently ncluded, Which serves to conceal structural'details and to present a better appearance, and to afford an advertising surface.

The brush 1 is of usual construction, consistin of a sewn sheat of broom-corn, properly shaped and trimmed. The butt-end of the sheaf is however capped and encased in a metal shoe 11 (formed ordinarly of sheet steel), riveted to the sheaf as indicated at 12. A central orifice is formed in shoe 11, and. surrounding this orifice is an inWardly eX- tending, screW-threaded ferrule 13. This ferrule 13 is preferably formed as a separate piece With flanged base, by Which it may be permanently united to the Web of metal Which forms the adjacent part of the shoe 11. The ferrule is preferably formed from sheet steel by stamping and thread-rolling. In Figs. II and VI an engagement of tongues 14: cut from and inturned from the substance of shoe ll upon the edge of the base fiange of ferrule 13, is shown This is itself not preferably the efiective means of unon of these parts; it is merely the means of initial as sembly, and is preterably 'followed by spot- Welding between the surfaces so assembled in contact.

In the building of the brush a central space s left extending inward in the aXial line of the terrule 13 When applied, a space such as to alloW the seated handle 2 (presently to be described) to extend through the *ferrule and inwardto the Zone of sewing A as indicated in Fi II.

The butt-end of the brush, beneath the shoe 11, and the* surtaces' of broom-corn spread apart to tonn within the brush a space for the entrance of the handle as described, are in the course TO rabrication, preterably coated With pitch.

The shoe 11 s split at its ends, as indip a screW-threaded band, adapted to engage the sCreW-threaded fel-rule 13, already *described. Thus adjacent the screW-threaded band a tapered surtace is *found for purposes presently to *be 'descrihecl. The construction in this particul'ar is clearly shown in Fig. II. When the handle is in place and seatcd and secured by the screW-threaded engagement here alluded to, the pointed end of the handle Will extend Within the brush to the Zone of sewing A. This inward extension of the handle Within the brush alords Strength, particularly Strength to resist the strain of service. v

The keeper 3, formed also, preferably, as a stamping of sheet steel, is shaped to fit snugly upon the shod butt-cnd of the brush, to be arched over the shoulders of the brush member leaving open Spaces 33 On either side, and by its fiaring ends 31 to make Wedging engagement upon the sloping shoulders 16 of the brush. The keeper is provided with a central Orifice around Which the metal web of the keeper 3 is crowned, as is indcated in the upWardly curved tapering rim 32. n

WVhen the parts are assembled, asshoWn in Fig. II, the Crown 32 Which surrounds the orifice in the keeper is engaged hy the conical surface of the terrule 21 of the handle, and the screwing of the handle home places the keeper 3 under strain: the flarng ends 31 of the keeper engaging the sloping shoulders 16 of the brush, yieldingly resist ,idle member applied upon the shod end of the brush l, and interposed between the brush l and the heeper 3, and clamped to place beneath the keeper. The shield t enn- 'sists merely O' opposite plates united by bridging Web or Webs 41. It is freely expansible, to shape itself to the butt-end ot the brush. Allowance is of Course made in the proportioning of' the other parts, for the resence of thls shield member t.

The shield member When in place covers and ooneeals the cheeks of the shoe ill, through Which riveting has been made, and, exposed Within the Spaces ::33 of the heeper, presents *fair smooth surfaees at these Doins. These fair smooth surfaees are oil* course available for advertising purposes.

The exposed met-al surt'aces may be coated,

eolored, and decorated as desired.

I claim as my invention.

1. In a broom the combination of a brush member provided with sloping shoulders and With a sereW-threaded bore extending in- Ward from its hatt-end, a handle provided at an interval from its tip With a serewthreaded band and, adjacent such band, with 35 a ta aered surface, and seated in the bore in the rush member, its screw-thieaded band engaging the screW thread of such bore, and its tip extending inWard heyond such region of engagement and into the body ol' the brush member, and a keeper of spring metal with Hal-ing' ends and with medial and crowned orifice overlying the butt-end of the brush member and surrounding the tapered surtace of the handle introduced Within the bore of the brush member, and engaged ai its crowned orifice by the handle and engagiun at its ends and under tension the shoulders ot the brush member while the handle, ntroduced into the bore within the brush member remote from Screwed-humm position, said keeper, 'when the handle is Screwed home in the brush member, being held under tension between suri'aces Which :it engages upon the shouldcrs of the ln'ush and upon the taper of the handle.

In a broom the combination ozl' a brush member enc'ased at its hatt-end in a sheetmetal shoe riveted to place upon it, said shoe beina' provided With a screw-threaded bore. a sm'ew-tbreadcd handle removabl seated in said bore, an arehed heeper overlying the shoulders of the brush member and sm rounding the handle when introduced in the bore of said brush n'lember, and a shield interposed between the brush memhe' and the lceepcr and overlying the riveted sides of the shoe, otherwise exposed Within the arch of the keeper.

In testimony Whereof I have hereunto set my hand.

THEODORE H. FRENCH.
