SPECIFICATION forming part of Letters Patent N o. 446,901, dated February 24, 1891.

Application led J' ulyr 9, 1890. Serial No. 358,221. (No model.)

To aZZ whom it may concern..-

Beit known that I, THOMAS J. THORP, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Brooms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to brooms having detachable handles, frames, and fastenin g-wires; and it consists in the construction hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation, partly in section, of my improved broom. Fig. 2 is a perspective of `a skeleton.- Fig. 3 is a central section of a binding device. Fig. 4 is a side view of a distance-piece, and Fig. 5 is a partial section showing devices for joining the brush and handle.

Numeral 1 indicates the body of a broomhandleconsisting of a tube, preferably nickelplated. The upper end is closed and iinshed by any suitable means, such as shown. A cap 2 has an internal screw-threaded opening 3, adapted to be screwed onto the threaded stem 4 of a plug 5, secured by any convenient means in the interior of the tube.

5 indicates projections or stops rigidly secured in the plug 5 by screw-threads, solder, or equivalent means, and Vextending through perforations in the tube. Said projections can be cast upon the plug and the latter introduced in the tube, the projections being entered in the proper openings before the longitudinal joint 1 of the tube is fully closed. The upper endof the tube having been entered in the cap 2 and the screw engaged with the socket in the plug and the cap screwed down until the tube bears on the bottom of the recess in the cap, suitable terminal that will properly hold the tube is thereby produced.

6 denotes a plug similar to that above described, provided With like projections e. It has a screw-threaded opening` 7 to receive a screw 8, formed on the plug 10.

9 indicates a skeleton having arms 11, which are secured to the plug 10 in a recess therein. Said skeleton is of special form, adapted to 14 denotes an approximately cone-shaped tube or thimlole which is made to receive and hold the bottom of tube 1, and which incloses the arms 11. These arms are a part of the skeleton 9, and are each fastened by rivets or other means on a side of the socket in plug 10. One of these arms appears in Fig. 5 se- I cured in place, the other being cut away. After the broom-corn has been laid and suitably formed about the frame 9 and its upper ends have been wired in usual manner the thimble 14 is forced down upon the shoulder ofthe broom at 15 by turning the handle 1 and its contained screw-threaded plug, so that they are drawn down upon screw S toward the brush or broom proper.

In addition to the usual tying and binding string, such as indicated at 16, I employ the wires 17, which are passed under the disks, buttons, or bars 18, placed at convenient intervals. The Wire ends are secured to the buttons by means of holes 19 or otherwise. Said buttons are arranged in pairs and connected through the broom-brush by means of wires secured thereto in any convenient manner. Preferably the wires are at one end permanently attached to one button and detachably fastened to the other by bending their ends down upon the same after having been passed through it, as shown at 19. Teeth 2O are provided to hold the buttons more securely in place.

, 21 is a distance-piece, notched at 22 to embrace the binding thread or cord, and perforated at 23 to receive the wire 17 These pieces operate to hold the wires in proper relativeposition, and are most advantageously placed in the edge of the broom.

IOO

The tubular handle, being made of light metal, is stiifened at each end by an interior plug and :1n external cap or ihimble. The split iu the tube enables the projections of the plugs lo be entered in holes in the tube when slightly. expanded, the longitudinal opening in the tube beingsnhscquently closed and the cap and thimble placed thereon.

\Yhen the brush of a broom is Worn out', a fresh one can be supplied to lehe frame and handle and bound with wire and thread, as set i'ortl1,orin anyapproved manner, and these devices of my invention can be reused many times with economy and convenience.

Having thus described myinvention, what I desire to secure by Let-ters Patent isl. A tubular broom-handle made of elastic material and having interior plugs at each end provided with projections cngagii'ig holes in said handle, a cap surrounding the upper ond and engaged with the plug, and a flaring ihimblc surrounding the opposite end, adapted to cover the upper end of the broom ber, substantially as set forth.

i. In a broom, the skeleton having the transverse outwardly-curved bars, Jelle intermediate connecting-bars 12', and arms 11, in combination with a tubular handle provided with a plug secured therein and secured to the arms ll of the skeleton, the latter being concealed wit-hin and supporting the broom and having a part of the same between its transverse members, Substantiallyas set forth.

In testimony whereof I have signed this specification in the presence of t'wo subscribing witnesses.

THOMAS J. THORP.
