7 Claims.

My invention relates more particularly to that;

class of brushes which are used for cleaning floors, walls, and similar large surfaces, and an object of my invention, among others, is to pro- 1 vide a simple means for attachment of a handle to the head of the brush, such attaching means being so constructed as to prevent injury to the lower end of the handle, or that part connected tothe brush head.

One form of a brush embodying my invention andin the construction and use of which: the ob-' the lower end of the handle afiixed thereto.

Figure 6 is a View on reduced scale illustrating an old type of brush wherein the handle is screwed directly into the head.

In a former type of brush of this class a wooden handle has been threaded at its lower end into a threaded socket in the head of the brush. An objection to this construction has existed by reason of the fact that the wooden threads on the stub at the end of the handle are readily broken off so that the connection soon becomes useless.

My improved brush illustrated and described herein embodies a construction which avoids such objections, such brush including a head I commonly composed of wood or similar material and within which a threaded socket 8 is formed, bristles 9 being secured to the under side of the head in any suitable manner and projecting therefrom.

My improvement comprises a connector for attaching the handle to the head, said connector being formed of wire disposed in helical shape. This connector comprises a stub ID the coils of which are made to fit the threads of the socket 8. Adjacent to the stub Ill an attaching socket II is formed in the same general manner as is the stub it with the exception that the socket is preferably larger than said stub, and the coils of this socket comprise a thread to receive the threaded stub I2 at the lower end of the handle l3.

Next to the socket H a supporting socket I 4 is formed of the same general shape as the stub l0 and socket l I, but larger in diameter than the socket H, andas clearly shown in Fig. 4 of the drawing.

The threaded stub i2 at the lower end of the handle is smaller in diameter than the main part l3 of the handle, the latter closely fitting the supporting socket M. This construction is such that the support by the socket lt of the lower end .of the handle in connection with the socket l i effectually prevents the threads on the stub i2 of the handle from being broken, and the life of the attachment is therefore greatly prolonged, in fact the handle and its attachment outlasting the head and bristles of the brush, whereas in the old structure, as illustrated in Fig. 6, the threads on the stub l2 of the handle it fitting within the threaded socket l5 of the brush head It readily become broken thereby rendering the connection useless.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.

I claim:

1. A brush including a head having a socket, a connector having its end adapted to be secured in said socket and including an attaching socket composed of helically wound wire formed to constitute threads for the threaded end of a handle, said connector also including a supporting socket also formed of helically Wound wire and larger in diameter than said attaching socket, creating a shoulder adjacent to and at the outer end of said attaching socket to receive a shouldered part of said handle adjacent said threaded end.

2. A brush including a head having a threaded socket, and a connector having its end composed of helically wound wire to fit the threaded socket in the head of said brush, said connector including an attaching socket composed of helically Wound wire formed to constitute threads for the threaded end of a handle, said connector also including a supporting socket also formed of helically wound wire and larger in diameter than said attaching socket, creating a shoulder adjacent to and at the outer end of said attaching socket to receive a shouldered part of said handle adjacent said threaded end.

3. A brush including a head having a threaded socket, and a connector having its end adapted to be secured in said socket and including an attaching socket composed of hellcally wound wireformed to constitute threads for the threaded end of a handle, said connector also including a supporting socket also formed of helically Wound wire and larger in diameter than said attaching socket, creating a shoulder adjacent toand at the outer end of said attaching socket to receive a shouldered part of said handle ad- J'acent the threaded end thereof.

4. A brush including a head having a threaded socket, a connector formed from a single piece of helically wound wire and including a stub the '1 turns of which form threads to fit said threaded socket, and an attaching socket the turns of which form threads to fit-the threadedend of a brush handle, said connector also including a supporting socket larger in diameter than said attaching socket, creating a shoulder at the inner end of said supporting socket, the turns of which supporting socket closely fit that part of the handle adjacent the threaded end thereof, said shoulder .forming a seat to receive a shoulder on said handle to support the latter and thereby relieve strains on the threads of the handle. 7

5. A brush including a head having a threaded socket, and a connector formed from a single piece of coiled wire and including a stub the turns of which comprise threads to fit said threaded socket, said connector also including an attaching socket the turns of which comprise threads to fit the threaded end of a handle, said attaching socket being larger in diameter than said stub and said connector also including a supporting socket larger in diameter than said attaching socket, creating a supporting shoulder, the turns of said supporting socket closely fitting that end of the handle adjacent said threaded end thereof and said supporting shoulder affording a seat for a shoulder on the handle to support the latter and remove strains on the threads on the handle.

6. A brush including a head having a socket, and a connector having its outer end adapted to be secured in said socket and including an attaching socket composed of helically wound wire formed at a distance from the inner end of said connector to constitute threads for the threaded end of a handle, said connector also including a supporting socket composed of helically wound wire extending from said attaching socket to the inner end of said connector to closely fit that part of said handle adjacent said threaded end and thereby remove strains from the threads on said handle.

7. A brush including a head having a threaded socket, and a connector having its outer end formed of helically wound wire adapted to be secured in said socket and including an attaching socket composed of helically wound wire formed at a distance from the inner end of said connector to constitute threads for the threaded end of a handle, said attaching socket being larger in diameter to create a shoulder to receive the end of the handle at a distance from the brush head, said connector also including a supporting socket larger in diameter than said attaching socket and extending therefrom to the inner end of the connector to receive that part of said handle adjacent the threaded end thereof.
