HENRY CAVE, OF HARTFORD, AND HORACE H. FITZGERALD, OF BERLIN, GO1\TNECTI- CUT, ASSIGNORS TO THE FULLER BRUSH COMPANY, OF HARTFORD, CONNECTICUT,

A CORPORATION OF CONNECTICUT.

HANDLE GONNECTER FOB IMPLEMENTS.

Application filed February 2, 1925. Serial No. 6,237.

This invention relates to the class of de vices employed for attaching implements, as brushes, mops and the like, to the handles therefor, and an object of the invention among others, is to provide a connector that shall be simple in'construction, that shall be durable, and that may be produced at a minimum cost.

One form of connector embodying our invention and in the construction and use of which the objects herein set out, as well as othorspnay be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a side View of a connector embodying our invention.

Figure 2 is a view in section on a plane denoted by the dotted line 2-2 of Figure 3.

Figure 3 is a view from a point located at right angles to the point of view of Figure 1.

Figure 4; is a View in section on a plane denoted by the dotted line 1-4 of Figure 1.

Figure 5 is an end view of the structure.

Figure 6 is a view in section on a plane donoted by the dotted line 66 of Figure 1.

The improved connector forming the subjoct matter of this application comprises a socket piece and a connector that is firmly and rigidly attached to the socket piece, this connector comprising spring arms having means at their outer ends for attachmentto a brush, mop or other implement. The socket piece is shown herein as in the form of a forrule at one end within which is received the end of a handle or similar member, in a mannor that will be readily understood, but it is contemplated as within the invention that the socket piece need not necessarily be formed separately from said handle and in a manner to receive the same, and it will, therefore, be understood that the term socket piece as employed herein contemplates this member whether it be formed separate from the handle and for attachment thereto, or otherwise.

In the accompanying drawings the numeral 7 indicates the socket piece as a whole comprising a ferrule 8 located at one end and a holder or head 9 located at the opposite end. The connector has branches or arms 10 connected by a bow 11 at one end, the opposite ends of said branches or arms being free. These branches or arms have resilient prop erties to enable fingers 12 at their ends to engage within sockets or openings in a cleaning implement, such implement not being shown herein.

A novel feature of this invention comprises the means for securing the connector to the socket piece. In effecting this result the socket piece is flattened at the holding end, as shown in Figures 3 and 4 of the drawings, and holes 13 are formed in the opposite sides of this holder or head extending from the end of the socket piece to an opening 14 therein, the holes 13 being substantially of the size of the wire or stock comprising the arms or branches 10. In the formation of the holes 13 the faces of the head are depressed into fiat portions 15 that rest against each other and as shown in Figure 6 of the drawings, the end of the connector comprising the how 11 being inserted in the headbofore the metal is depressed to form the flat portions 15, this latter operation firmly securing the connector within the head.

In the operation of securing the connector within the head the socket piece is first fiattened at its end into an oblong slot of a width substantially'tha t voftho diameter of the wire or stock comprising the connector. The U-shapod end or how of the connector is then inserted to the position shown in Figure 2, and the head is then acted upon as by means of dies to depress the portions between the arms forming the flat surfaces 15, thereby completing the operation. A bow shaped hole is thus formed in the head, one side of which hole is open into the large hole in the ferrule 8, and the bow shaped end of the connector is thus caused to nicely fit said how shaped hole and be securely fastened therein.

In many instances of usetho fingers 12 are inserted in holes oppositely disposed in the implement to be attached to the connector and in order to retain the fingers against accidental displacement from said holes a spreader 16 is employed having a loop 17 at one end by means of which it is pivotally attached to one of the branches or arms 10, the other end of the spreader having a hook 18 to engage over the other arm or branch of the connector, and with a lip 19 by means of which this end of the spreader may be disengaged from said branch by swinging the spreader on a pivot formed by the loop 17.

It will be noted that the formation of the bow shaped hole 13 provides a shoulder 20 within the head 9 engaging within the bowed portion of the connecter, said shoulder serving as an obstruction rigid with the head to effectively prevent removal of the connecter from the head.

In accordance with the provisions of the patent statutes we have described the principles of operation of our invention, together with the device which we now consider to represent the best embodiment thereof; but we 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.

We claim- 1. A handle attachment including a socket piece formed of a single piece of material with a socket at one end for the reception of a handle, said socket being closed at the bottom thereof except for spaced openings extending from the socket lengthwise of the socket piece and out at the end thereof, and a connecter comprising arms located within said openings and a bow engaging the bottom of said socket.

2. A handle attachment including a socket piece having a socket at one end for the reception of a handle and an enlarged head at the opposite end having spaced openings extending from the socket lengthwise of the socket piece and out at the end thereof forming shoulders, said socket being closed at the bottom except for said openings, and a connecter comprising arms located in said openings and a bow V seated against said shoulders and against the bottom of said socket.

3. A handle attachment including a socket piece having a socket at one end for the reception of a handle and a head at the opposite end comprising opposite walls located substantially in contact and with openings on opposite sides of said walls extending from said socket lengthwise of the socket piece and out at the end of the structure, and a connecter comprising arms located within said socket piece and a bow engaged with the ends of said walls.

4t. A handle attachment including a socket piece having a socket at one end for the reception of a handle and an enlarged head at the opposite end comprising opposite walls located substantially in contact and with openings on opposite sides of said walls forming shoulders extending from said socket lengthwise of the socket piece and out at the end of the structure, and a connecter comprising arms located within said openings and a bow engaging said shoulders and the ends of said walls. I

5. A handle attachment comprising a ferrule round at one end and with its opposite end wider in one direction and narrower in the other with the intermediate portions of opposite walls meeting to form two spaced openings extending lengthwise of the socket piece and out at the end thereof from said socket, and a connecter comprising arms located in said openings and a bow engaged with the abutment formed at the bottom of the socket in the ferrule and between said openings.
