PATENT OFFICE.

UNITED STATES JOSEPH WILMER WOHLHIETER, OF IRVING'ION, NEW JERSEY, ASSIGNOR TO KEY- STONE STAMPING CORPORATION, A CORPORATION OF NEW JERSEY.

, MOPSTICK HEAD.

Application filed July 25,

This invention relates to combination mop stick heads of the type having means such as a groove along the outer edge in which a mop cloth or cards may be clamped by a bail wire and also having means for clamping a brush back in order that the same head may be used to hold either a brush or a mop.

It is the purpose of this invention to provide a mop stick head which may readily be used for either purpose and which will rigidly hold a brush back when so used without permitting the brush to slip and bec=mie disengaged as well as hold a mop when so desired. It is an object of this invention to construct such a combination head of the lever action type whereby a single bail wire actuated by a single lever may be utilized for both purposes.

Devices of this type usually employ a head for attachment to a stick having a groove in the outer end and a cooperating bail or clamping wire between which a mop only may be clamped, the bail wire being actuated by a lever yieldingly pivoted to the head through connection with a coil spring surrounding the stick or handle, other means being provided to clamp a brush thereto.

In accordance with this invention I utilize the same head, lever, and clamping wire to hold a mop or a brush back by constructing the head with a laterally projecting foot or hook member or a plurality of such hooks between which and the bail wire a brush back may be securely clamped, the mop being held, in the alternative, as usual between the channeled end of the head and the bail wire.

In order to secure a positive gripping action between the head and the bail wire and also between the hook and the bail wire, the wire is so mounted and attached to the lever that upon partial movement thereof the bail wire is first moved toward the mop head a and then upon further movement of the lever is positively moved directly toward the hook member. When a plurality of hook members are used they may be made from one stamping and spaced from each other in order to permit the handle end of the lever to pass therebetween when the bail Wire is in open position.

.A more detailed description will be given in connection with the drawings, in which:

1927. Serial No. 208,158.

Fig. 1 is a front elevation oi a mop stick head constructed in accordance with this invention;

Fig. 2 is a side elevation of a mop stick head constructed in accordance with this invention illustrating a brush in clamped position, and

Fig. 3 is a rear elevation of the same.

In the illustrated embodiment of this invention a sheet metal stamping l is bent upon itself at 2 to bring the two faces together to form a cross head, the free ends being bent outwardly and surromulcd by a channel or U-shaped end member 3 securely clamped around the free ends of the stamping or cross head 1. The center portion oi? the folded edge 52 is split and spread to term a socket elto receive the end of a handle 5. The head 1 has a pair of hooks 6 formed from a single stamping 7 projecting laterally therefrom, wlnch serve as one element ot a clamp for securing a brush to the head.

The stamping 1 may conveniently be formed with a pair of prongs S which extend through slots cut through the stamping and may be bent sharply over to secure the stamping 7 to the head member and also to hold the two faces of the head member rigidly together.

The usual coil spring 9 surrmmds the end of the mop stick 5 which into the cross member, the corresponding end of the spring being secured to the cross head and stick by means of a staple 10, and the remaining portion of spring 9 being free to slide axially upon the stick.

A lever 11 is provided having a tonguelike extension 12 bent around one convolution of spring 9 upon the same side of the handle as the projecting books 6 to constitute a pivotal connection 13 thereto. A. bail wire or clamping element 14 extending upwardly and over the end of the cross head has its ends pivotally secured to lever 11 at points 15 upon two projecting cars 16 formed on the lever, the points of attachment being removed from the connection 11; in such manner that when the lever 11 is swung about connection 13 as a pivot the bail Wire will be moved accordingly toward or from the head in a particular manner later to be described. The fulcrum point of the lever 11 being upon a spring, the pivotal point is adjustable and will yield and auto-' and between'the sides of the channeled end of the cross head, the bottom wall of the channel being cut away at the extreme edges for this purpose. The rear side wall thus acts as a fulcrum when the lower end of the bail wire is moved inwardly toward the handle, thus causing the upper projections 19 to move directly toward the hooks 6, resulting in a positive clamping or vise-like action therebetween.

The pivotal point 13 is placed upon the same side of the handle 5 as the hooks 6 and the length of the bail wire and distances be tween the pivotal points 15 and 13 are so chosen that in moving the lever 11 from its uppermost position, which may be from between the hooks 6 when opened to receive very large brushes, to a midposition as shown in Fig. 2, the bail wire 14: is moved bodily downwardly till the portion 18 there- .of contacts with the channeledend of the head when no brush is in place. Further movement of the lever 11 will swing the wire 11 about the rear wall of the channel as a fulcrum and move the projecting portions 19 directly toward the hooks 6 thus clamping a brush back securely therebetween.

It readily can be seen that from the arrangement of ivots as above described in combination with a yielding fulcrum point, the same head may be used to rigidly hold either a brush or a mop.

It is obvious that many changes may be made in the details of construction without departing from the spirit and scope of the invention as defined in the following claims.

I claim:

1. In a mop the combination of a mop handle with a sheet metal head member mounted thereon and having a pair of spaced hooks projecting laterally from one side thereof, a lever pivotally connected to said mop handle on the same side thereof as said hooks and adapted to swing between said hooks and a clamping wire secured to said lever and extending beyond and bearing against said head member adapted to be moved toward said head upon partial movement of said lever and toward said hooks upon further movement of said lever.

2. In a mop the combination of a mop handle with a sheet metal head member mounted thereon and having a pair of spaced hooks projecting laterally from one side thereof, a lever pivotally connected to said mop handle upon a resilient fulcrum positioned upon the same side of said handle as said hooks, said lever being adapted to swing between said hooks and a clamping wire sccured to said lever extending beyond and bearing against said head member and adapted to be moved toward said head upon partial. movement of said lever and toward said hooks upon further movement of said lever.

3. A mop head including a head member having a U-shaped outer end, the bottom of which is cut away at the outer edges and having a pair of hooks projecting laterally therefrom, a lever pivotally connected to said mop handle at a point upon the same side thereof as said hooks and adapted. to swing between said hooks and a clamping bail secured to said lever and extending beyond said head member, the sides of the bail being positioned for movement within said edges of said head member, the bail being movable bodily toward said head member upon partial movement of said lever and pivotally about said head as a fulcrum toward said hooks upon further movement of said lever.

1. A combined mop and brush-holding head having a portion adapted to have a mop clamped thereto and formed of: separate members connected together and having portions forming a socket for a mopstick, one of said members being formed with stops located to the rear of said first-referred-to portion for engagement with a brush-head applied to said holding head, and a clamping jaw, for the purpose set forth.

5. A combined mop and brush-holding head liiwing a portion adapted to have a mop clamped thereto and formed of separate members connected together and havin portions forming a socket for a mop-stie one of said members having portions extending laterally from the other of said members and presenting shoulders located to the rear of said first-referred-to position for engagement with a brush-head applied to said holding head, and a clamping jaw, for the purpose set forth.

In witness whereof, I hereunto subscribe my signature.

JOSEPH VVILMER W Ol-ILHIETER.
