INVENTOR. 15km/,4M ll. ZucA/f@ ww n YN @N Sept. 13, 1955 A. H. zUCKER MOP HANDLE WITH HEADLOCKING MEANS Filed Sept. 27, 1952 United States Patent()vv p 2,717,405l Mor HANDLEWITH HEAnLocKlNG MEANS Abraham H. Zucker, Cleveland Heights, Ohio i i Application September27,` 1952,Serial No. 311,830 i 2 Claims. (Cl. 15.-147) I'his invention'relates to improvements in a mopconstruction, and more particularly, to an mprovedmop head construction which permits the mop head Vto 'be quickly and easily operated by rotating a sleeve mounted on the handle.

An objectvof the invention is to provide a construction permitting the mop head to be controlled by merely rotating a sleeve on the handle in such manner that rotation of said sleeve in one direction causes the head to retain a cloth therein, while rotation in the opposite direction causes the release of the cloth.

Other objects are, to provide a mop adapted to be formed from a relatively few simple parts, which are relatively inexpensive to manufacture and assemble. V

Other objects are, to provide a construction which is quickly and easily operated, positive in action and durable 1n use.

These and other objects will be apparent in the course of the following specification.

In the drawings, forming a part of this specification:

Fig. l is a perspective view ot' an embodiment of my invention showing a mop cloth mounted therein;

Fig. 2 is a fragmentary sectional view showing the invention;

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2;

F 4 is an elevational view of the carrier;

Fig. 5 is an elevational view of the collar or bushing;

Fig. 6 is a view of the operating sleeve, partly in section;

Fig. 7 is a view of the lower end of the mop handle showing slots;

Fig. 8 is an elevational view of the operating pin, while Fig. 9 is an end view of the operating pin showing the tapering at one end thereof.

In the drawings of this illustrative embodiment of my invention, the numeral 10 refers generally to a mop including a tubular handle 11, having an elongated collar 12 provided with a iiange 13 and two oppositely disposed longitudinal slots 14. The collar 12 may be secured to the mop handle 11 by a pressed fit, or by any suitable means. A short collar 15 is disposed at the top end of the collar 12 and secured thereto by means of a pin 16 which also secures the collar 12 to the handle 11. The handle 11 is provided with two oppositely disposed slots 17 matching the two collar slots 14. The collar flange 13 and collar 15 serve to restrain an hereinafter described operating sleeve from longitudinal movement along the handle 11. If desired, annular beads may be formed on the handle 11 to perform the same function as ange 13 and collar 1S.

An operating sleeve 18 rotatably mounted around the elongated collar 12 and provided with a knurled outer surface indicated at 19, is restrained against longitudinal movement along the handle 11 as above described. An operating pin 20, illustrated in Figs. 2, 3, 8 and 9, is provided with a ,at tapered surface 21 for permitting slight movement in the slots 14 and 17, for properly ICC YL, aligning reduced tapered ends 22 disposedfon the'iend's of operating `pin with aspiralv thread v23,]disp'osedv on the interior of the operating sleeve 18 Vasshown in Figs. 2, 3-and 6. The at'taperedsurface 21 of the 'pin 20 is requiredfo'r the reason that the oppositely disposed longitudinal slots- 14 -in the collar 12 require clearance for the outer circumferentialshoulders of'pin 20, which cannot exactly tit the bore of the operating sleeve 18 without binding, however, with thefslight taperllion the end of pin' 120, the' slot 14 in collar 12 allows thepinfzf'to move from one sdefto the other ofthe centerline of sleeve 18 as it isrOtated. l'Rotationl ofthe sleeveV 18 in `one direction will carry the operatingpin 20 in one longitudinal direction of the handle, 'while rotation of the sleeve v18- in the opposite direction wilbca'rry-'the pin 20 in the? opposite direction, in an-^obvious manner;

A carrier illustrated in Figs-:z and 4, having epee tures25 receiving the-operatin'g Vpin 20, andhaving e reduced lower end portionv 26 receivingl hooks y27V on the ends ofa mop supporting frame 28,'llustrated in i', Fig.` 2, is reciprocably mounted lwithin the handle 11,

- so that it maybe carried longitudinally oflithe handle 11 by the operating pin 20, as previously explained. A mop cloth 29, disposed between parallel arms 30 of the frame 28, may be of any suitable construction, as will be readily understood. Means, other than the frame 28 and associated parts may be used to retain the mop cloth for locking it securely at the Vend of the mop handle.

Two oppositely disposed notches 31 in the bottom margin of handle 11 are adapted to receive the upper arm of the mop supporting frame 28 and securely retain the frame 28 in the notches 31 on the lower end of the handle 11, whenever the carrier 24 is reeiprocated to its upper position by rotation of the operating sleeve 18,

where it remains firmly locked until rotation of the sleeve 18 in the opposite direction releases the frame 28 from engagement with the mop end notches 31. If desired, the operating ksleeve 18 and associated parts may be disposed at any convenient location along the handle 11, for example at the opposite end thereof, and the same may be accomplished, by usingan elongated connecting member, such as a flat strip of material or wires secured to the carrier 24 at one end and secured to the mop frame 28 at the opposite end. Such constructions are within the contemplated scope of this invention, as the same may be accomplished by adding well known structure to my device in an obvious manner.

It will be obvious that the mop disclosed herein may be formed of any suitable material such as steel or the like. The construction disclosed may be utilized with equal success with various types of mop cloths. 'Ihe user of this mop is only required to rotate the operating sleeve 18 with one hand while retaining the mop handle 11`in the other hand, in order to clamp or release the mop cloth 29, as previously explained. The handle 11r may be formed of conventional tubular stock which requires a minimum number of manufacturing operations. The operational parts are all enclosed in the handle 11 where they are protected from molestation and breakage. If desired, the handle may be formed of solid material which will have certain cut-out portions.

It will be apparent to those skilled in the art that the invention disclosed herein may be variously changed, used or modified without departing from the spirit of the invention, and that the present embodiment of the in- `vention isillustrative only and that my invention is not limited thereto.
