MOP

Alvin A. Bohnenblust, Kansas City, Kans, as-

signor, by mesne assignments, to Harry E. Lindstro'm, Sedalia, Mo., doing business under the name of Acme Broom Company.

Application September 8, 1941, Serial No. 409,920

2 Claims.

My invention relates to improvements in mops. It relates particularly to a type in which a molded soft rubber handle socket is pivoted to a wire foot adapted for insertion into the pocket of a shag.

One of the objects of my invention is the provision of a novel means for pivotally connecting the socket member to the foot member, which pivotal means is simple, cheap, strong, durable, not likely to get out of order and is efficient.

A further object of my invention is the provision of a novel pintle or pivot pin, which is molded in the socket member, and which is easily and quickly disposed in the mold, and after being embedded in the socket member will be held securely therein and not work out endwise.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which illustrates my invention:

Fig. 1 is a plan View of a mop provided with my improvement, a portion of the shoe shag being broken away.

Fig. 2 is a section on the plane of the line 22 of Fig. l, with the shoe shag removed.

Fig. 3 is an enlarged section on the line 33 of Fig. 1, showing the pivot pin with fiat bevelled ends.

Fig. 4 is a side view of the pivot pin, shown in Fig. 3.

Fig. 5 is a rear view, partly in elevation, partly in vertical section and partly broken away of my .improved mop, provided with a modified pivot pin, which has tapering bevelled ends.

Fig. 6 is a side view of the pivot pin shown in Fig. 5.

Similar characters of reference designate similar parts in the different views.

I designates a portion of the toe of a usual mop shoe having the usual shag 2 and a pocket for receiving a wire foot member.

In my improved mop the foot member comprises a piece of spring wire having a portion 3, forming the front end and sides, and having the shape of the contour of a half sole, the front end portion being insertible into the shoe pocket 4. which the foot member spreads and holds taut.

At the rear end of the foot member, the portions 3 have return bends which respectively merge into two forwardly converging portions 5, which extend to the middle portion of the foot member, and are there provided with return bends which merge into two rearwardly extending portions 6, having at their rear ends two parallel, spaced apart eyes i having the same horizontal transverse axis.

8 designates a connecting member having means for engaging a handle, comprising, as shown, a socket 9 in which is fitted one end ofa handle Iii.

The connecting member 8 may be composed of different materials, but I prefer to employ a plastic material, such as soft rubber, which can be cast into form in a mold. However, any of the usual materials capable of being formed into the desired shape, such as hard rubber, brass, or usual market plastics may be used and be included in the scope of my invention.

At its lower end the connecting member 8 has portions H at and against the distant sides of the eyes 1. The member 8, preferably, may have also, as shown, a portion l2 between and against the eyes 1.

The portions 3, 5 and 6 of the foot member are disposed in the same horizontal plane, enabling them to be easily slipped into th pocket of the shag shoe.

Extending through the eyes I and portion I2 and into the portion H is a pintle or pivot pin l3, Fig. 3, which is disposed, as is the axis of the eyes 1, in the middle horizontal plane of the portions 3, 5 and 6 of the foot member. The ends of the pivot pin I3 are embedded in the portions l l to hold the pivot pin from endwise movement and working out at either end, due to hard usage. In case of deterioration of the soft rubbeer or other pliable material, of which the connecting member 8 is composed, such as, after long use, would permit the working out at either end of the pivot pin, the portions 5 of the foot member, are located adjacent to the portions H and would stop further working out of the pin.

It being cheaper to cast the connecting member 8 in a mold, such is the preferred way of making it. When so made, the pivot pin 13 is first placed in the mold and the material then poured therein. During such pouring operation, the pivot pin sometimes shifts endwise until one and hits the wall of the mold. It has been determined by test that in such case, if the striking end of the pin is at right angles to its axis, sufficient material will not cover the end of the pin to hold it from working out.

By having the ends of the pivot pin bevelled. or oblique to its axis, as shown in Fig. 3, sumcient material will cover the ends of the pin to hold it in operative embedded position, even if an 1end of the pin has contacted the wall of the mo (1.

By having the ends of the pivot pin bevelled, as shown in Fig. 3, and as shown in Fig. 5, no special care need be used in positioning th pin in the mold, thus effecting a reduction in cost of manufacture.

In the form shown in Fig. 5, the bevelling of the ends of the pivot pin I3 is in the form of circular tapering, which form also provides for suiiicient rubber material engaging the ends, to prevent working endwise of the pivot pin, should one end of the pin have been against the mold wall during casting.

In all other respects the form shown in Fig. 5 corresponds to what has been described with reference to the form shown in Fig. 3.

In the making of the foot member, when the pivot pin is cast in the material poured into the mold, the eyes 1, in being formed, are left sufficiently open for the pivot pin to slip into the eyes, after which the eyes 1 are clinched to embrace the pivot pin.

To keep the foot member and the shoe from too free oscillation on the pivot pin, while being free to swing on the pivot pin, the portions II and I2 of the connecting member 8, may be of such relative widths as to afford between them and the eyes 1 a small amount of frictional resistance.

Other modifications of my invention, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is:

1. In a mop of the kind described. in combination, a wire foot member having its ends terminating respectively in two parallel spacedapart eyes having the same transverse axis, a connecting member having handle attaching means and having portions at the distant sides of and between said eyes, and a separate pintle extending through said eyes and said portion between said eyes and having its ends respectively embedded in said distant portions.

2. In a mop of the kind described, in combination, a wire foot member having its ends terminating respectively in two parallel spaced apart eyes having the same transverse axis, a connecting member having handle attaching means and having portions at the distant sides of and between said eyes, and a separate pintle extending through said eyes and through said portion between said eyes and having bevelled ends respectively embedded in said distant portions.
