BROOM.

SPECIFICATION forming part of Letters Patent No. 701,395, dated June 3, 1902.

Application filed March 2'7, 1902. Serial No. 100,292. (No model.) i

To aZZ whom it may concern.-

Be it known that I, ELIJAH ROBERTSON, a, citizen of the United States of America, residing at Paragould, in the county of Greene and State of Arkansas, have invented certain new and useful Improvements in Brooms, of which the following is such a full, clear, and exact description as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part hereof,

This invention relates to improvements in brooms; and it consists in certain novel features hereinafter described and claimed.

In the accompanying drawings, which fully illustrate my invention, Figure 1 is a front elevation of a broom provided with my improvements. Fig. 2 is an edge elevation of the same. Fig. 3 is a vertical section of the same, and Fig. 4 is a detail View of the fastening-bolt. 7

In carrying out my invention I employ a handle A, having its lower end cut away on its opposite sides, as shown at B, and above the cut-away portions I form longitudinal grooves O in the sides of the handle. The lower cut-away end of the handle extends down into the straw or other material D,constituting the broom-head, and the said material is bound firmly together and to the handle by bracing and clamping wires. A base wire E passes diametrically through the handle near the lower extremity thereof and has its ends formed into eyes or loopsF, which project just beyond the edges of the broomhead and through which are inserted internally-threaded sleeves G, as clearly shown. Fitted in the opposite ends of the sleeves are clamping-bolts H, adapted to be turned up to tighten the clamping-wires I against the straw, and thereby hold it firmly in place. The base-wire E aids in holding the straw, as it furnishes a firm base against which both clamping-wires act, and as it passes through the handle it also serves as a stationary sup port for the threaded sleeves, which in turn prevent lateral spreading of the straw. The clamping-wires are mounted on the fastening-bolts by means of eyes J at their ends, through which the bolts are inserted into the I of the broom-head, as shown in Fig. 2.

sleeves. On each side of the broom-head I provide a supporting-frame composed of a single wire given the following formation: The ends of the wires are barbed, as at K,

I and driven into the handle in the base of the groove 0. From the barbed ends the wire is carried down to the end of the groove 0, whence it is carried outward in an'arc L, corresponding to the arc described by the top of the broom-head, the ends of the arcs terminating in loops or coils M, encircling the fastening-bolts. From the coilsM the wires pass to a point slightly below the bolts, where they are turned inward over the edge of the broom and doubled on themselves to form hooks N. The wires are then carried a slight additional distance downward along the edge of the broom, this lowermost portion 0 being carried slightly outward laterally to permit the desired flaring of the straw, as shown in Fig. 1, and alsoiinward toward the central. plage t the lower end of the portion 0 is formed a shoulder or bend P, and connecting'the two shoulders of the frame is a straight bar Q, passing over the side of the broom'head. The two frames on the opposite sides of the broom-head are connectedby links or rings R, passed around the shoulders, as shown most clearly in Fig. 2. By means of these supporting-frames the straw is confined below the clamping-wires, so that scattering of the straw is prevented, and the fastening bolts are suspended on the handle as well as supported by the ends of the base-wire. Twisting of the threaded sleeves is thereby prevented. To impart additional strength to the device, I employ brace-wires S, which have their ends arranged over the ends of the supporting-frames and are then carried down and outward to the hooks N, where they are doubled upward on themselves, forming eyes T, engaging the said hooks and connected by a bar U, passing across the side of the broom-head. These brace-wires form a support to prevent the supporting-frames dragging the ends of the base-wire downward and also aid in preventing the spread of the straw. To hold the ends of the brace-wires and also to give a neat finish to the broom, I

fit a cufi or clamping-band V on the handle, which passes over the ends of the wires, and thereby clamps the same within the groove, as will be readily understood on reference to the drawings.

My improvements provide a broom of great strength without excessive weight, and the construction is such as to eliminate all sharp angles or edges which would scratch furniture.

The fastening-bolts may be adjusted to give the broom-head any desired flexibility, and worn straw may be readily removed and a new head of straw substituted.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with the broom-head and the handle extending thereinto, of a basewire inserted through the end of the handle and projecting beyond the edges of the broomhead, internally-threaded sleeves held by the ends of said wire, fastening-bolts fitted in the ends of said sleeves, and clamping-wires mounted on said bolts and passing across the faces of the broom-head.

2. The combination with the broom-head and the handle, of a base wire inserted through the handle and projecting beyond the edges of the broom-head, clamping-bolts supported by the ends of said wire, clampingwires carried by said bolts and passing across the broom-head, supporting-frames secured to the handle above the broom-head, passing therefrom to and encircling the clampingbolts, and provided with hooks below the bolts, and brace-wires also attached to the handle above the broom-head and diverging downward therefrom and engaging the hooks on the supporting-frames.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

ELIJAH ROBERTSON.
