MOP HEAD Filed March 4, 1940 NVENTOR M, #md/Q7 Patented Oct. 20, 1942 UNITED STATES PATENT OFFICE MOIHEAD Robert L. Horsley, Memphis, Tenn.
Application March 4, 1940, Serial No. 322,049
This invention relates to mop heads of the class manufactured and shipped apart from the sticks or handles with which they are to be used.
One object of the invention is to provide mop heads of this kind which may be attached to plain ordinary mop or broom handles; another object is to provide mop heads of this character Which are neat and efficient and which avoid undesirable exposure of points and angles of metal; and a still further object is to provide such heads which are elicient and durable and which may be produced with a minimum expenditure of time and labor.
The following is a specication of my invention, reference being had to the accompanying drawing, in which Fig. l is a side elevation of a short-length head; Fig. 2 is a side elevation, showing the preliminary arrangement of the constituent parts prior to forming the mop head; and Fig. 3 is a longitudinal sectional View of the completed mop head.
The mop heads are formed from three elemental parts, namely, mop material I0, a U-shaped Wire loop I I, having pointed extremities on rightangular prongs I3, and a cylindrical ferrule I2 having a comparatively thin puncturable Wall. To form the mop head, the constituent parts are assembled in the manner shown in Fig. 2, with the mop material IB caught in Wire loop II and with the sides of the wire loop disposed on opposite sides of ferrule I2. Now, the ferrule is forced farther down in the wire loop, compressing the mop material between the end of the ferrule and the bottom of the wire loop. In this position the sides of the Wire loop are forced in- Wardly, pushing the pointed prongs I3 through and piercing opposite sides of the ferrule wall, Where the prongs are bent down into hooks lying inside and engaging said wall. The bottom edge of the ferrule being pressed against the mop material will sink into it and produce a cupped-in effect, in the manner shown at I5 in Fig. 3, and seat the mop against lateral movement on the end of the ferrule.
To attach the head to a handle it is necessary only to insert the end of the handle in the open end of the ferrule and drive a small nail through hole I4 into the handle.
It has been stated hereinabove that the ferrules I2 have puncturable Walls. In practice I use 24 gauge and 26 gauge metal for forming the ferrules, the heavier ones being used in heads for janitors and rooiers and the lighter for mops for household use. In the thicknesses of metal named the Walls of the ferrules, While under longitudinal pressure, are easily pierced by the pointed prongs I3 of the wire loops in the prooess of constructing the heads. The points of the prongs may contact and pierce the sides of the ferrules anywhere up and down their lengths or the prongs may, in cases Where the individual wire loops used are of suiiicient length, lap over the top edges of the ferrules and be bent down.
In the production of these heads I employ special mechanical means for assembling the parts for forming same. Said mechanical means being clearly set forth in patent issued to me October 11, 1932, No. 1,882,605, all persons interested in the manufacture of these mops are hereby referred to said patent.
In a mop head comprising a metal cylindrical member adapted to receive a handle in one end thereof, mop material, and a wire loop in which the mop material is held and secured under pressure against the opposite end of said member, the end portions of said loop lying along the exterior of the wall of said member and having pointed extremities extending through the wall of said member into the interior thereof, said pointed extremities being bent over against the inner surface of said member to secure them in said member, the wall of said member being readily penetrated by the pointed extremities of said wire loop, whereby said extremities of the loop can penetrate said member at any desired point depending upon the amount of pressure imposed on the mop material in securing the latter between said loop and member.
