TO ALL WHOM IT MAY CONCERN:

Be it known that I, JUsTUs DAY, of Holley, in the county of Orleans, and State of New York, have invented a certain new and useful improvement in Broom-Clamps and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

Figure 1 is a face view of my improved broom-clamp in the act of closing to compress the broom-stuff.

Figure 2 is a similar view, closed. V

Figure 3, an edge view. 7

Figure 4, a cross-section in line a: m.

Figure 5 is a face view, looking on the opposite side from figs. 1 and 2.

Like letters of reference indicate corresponding parts in all the'figures.

This invention is an i'mprovement on that patented to moon the 27th of November, 1866, (No. 59,977,) and on which a reissue has just'been allowed. In that case a round socket is made in the levers constituting the clamp, with'both sides of the socket bevelled down to the centre, and a slot is cut in the lovers transversely and longitudinally, which extends around or past the socket, to enable the wire used in the broom-head to be inserted and wound. Since the lovers are made of wood, for the purpose of economy, it is found that the slotting of the same,-in addition to the cutting of the sockets, has a tendency to make them frail and easily broken.

My present invention consists in theemployment, in combination with the levers, of circular caps or blocks, seeuredontside the lovers, corresponding with the socket, and leaving between them and the levers a slot corrcspondingin purpose to thatin the first invention, By this arrangement not only is greater strength secured to the levers, but the binding-wire is much .nore easily manipulated.

As represented in the drawings, the construction is similar to that of the-aforementioned invention.

A B are the levers constituting the clamp. They are connected at the front end by links or straps G, and at the rear end by a catch, H. Round sockets E F are employed to compress the broom-stuff in form for winding the upper end. Wires G Gr are employed to hold and guide the broom-stufi' in the sockets, as the lovers are closed, and when this is accomplished the wires are withdrawn. Instead of bevelling the sockets E F from-both sides to the centre, as in. my first invention, 1 bevel them from only one side, thus leaving the throat or narrowest portion at the opposite side, as shown in fig. 4. And, instead of cutting the transverse slots D tirough the body of the levers. I form them by securing caps or blocks M M to the sides of the levers surrounding the sockets, with a space between, as clearly shown. Thus arranged, the winding-wire, shown by red lines, is

passed through the slot or space D, around and around the hroom-stuff in the some manner as described in my aforementioned patent.

The great advantage of this arrangement consists in preserving the strength of the wooden levers by cutting them away as little as possible, and in greatly facilitating the winding of the wire, by bringing the operation to the outside of the lovers instead of through them. The operator, by this means, is enabled to hold the wind of the wire much more effectually, since he can reach much nearer the work. In addition to the above, the clamp is made much cheaper than before. The lovers are made to reverse, and the same flattening sockets K K are employed as in my first invention.

What I claim as my invention, and desire tosocurc' by Letters Patent, is-

The employment of the caps or blocks M M, attached outside the clamp, and leaving the slot or space 1) for the winding of the wire, as herein set forth.

In witness whereof I have hereunto signed my name in thepresence of two subscribing witnesses.
