April 5, 1955 L. WILSON 2,705,336 CLEANING INSTRUMENT HAVING A DETACHABLE HANDLE PROVIDED WITH A CAP Filed Dec. 5, 1948 United States Patent CLEANING INSTRUMENT HAVING A DETACH- ABLE HANDLE PROVIDED WITH A .CAP

Ludwig Wilson, Chicago, Ill., assignor to Illinois Duster & Brush (30., Chicago, 111., a corporation of Illinois My invention relates to handles or sticks for brushes, mops and like articles and particularly to a reversible improved brush or mop handle and a removable end thimbleor cap that will fit over either end.

The invention has among its objects the production of an improved device of the kind described that is convenient, inexpensive, efficient, and which in an emergency provides a time saving repair, since in the event of the fracture or breaking off of the threaded end which is adapted to engage the brush, mop or the like, the stick may be reversed in a moments time and without delay, annoyance and expense in locating or providing a new stick. It provides a double life handle.

It also has a further object the production of a handle which may be conveniently and comfortably handled providing a cushion that is easy on the sweepers hands, minimizing rubbing and blisters. It gives a firm, easy to handle grip that speeds up sweeping or mopping. Should the brush or mop handle be set or leaned against a wall or door, the same will not mar the wall or door. Further, in the event the free end of the handle is accidentally pushed in the face or body of a child or adult while the brush is being used, the cushion grip provided by the crowned end of the cap will minimize the likelihood of injury.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosures herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawing, wherein like reference characters inclicate like or corresponding parts:

. Fig. l is a sectional view of a brush provided with my improved handle;

Fig. 2 is an enlarged view Fig. 3 is a sectional view and Fig. 4 is a view partly in elevation with the cap in section showing the cap applied to an end of the handle when a portion of the threaded end has broken oif.

As shown in Fig. l, 1 represents a handle or stick, as it is often called, usually of wood and threaded at both ends, either of which is adapted for threaded engagement in a socket 5 of the brush, mop or the like, by means of which the brush or mop may be easily manipulated. In the particular illustration of the invention shown, the back of the brush 4 is provided with two threaded sockets so that the brush or mop may be turned around and either socket utilized so as to equalize wear on the bristles.

The handle as shown in Fig. 2 is also provided with an outstanding screw threaded neck 3 similar to threaded neck 2 at the opposite end, at which end a cap or thimble 6 preferably of rubber or other resilient and yieldable material, may be removably placed. The cap or thimble 6, which is crowned at its closed end, is provided with a tubular bore 7 of a diameter to closely fit the body of the stick or handle adjacent the juncture with the threaded portion, and if desired the same may be pro vided with a shoulder at the juncture of the bore 7 and a reduced bore 8. While it is primarily intended that the cap will closely fit and be retained on the handle by frictional engagement on the end portion 9 of the handle, depending upon the length of the threaded portion 3, the threads may engage in the cap at the reduced porof the handle and cap 6; through the cap or thimble,

tion 8, increasing the holding thimble on the end of the handle.

In practice the threaded portion 2, which is shown engaged in one of the sockets 5 of the body -4 of the brush may break off (see Fig. 4). In. this instance it has heretofore been necessary to provide a new handle with inconvenience, expense and delay in securing the new one. With the present invention the cap or thimble 6 may be readily removed from either end and the stick reversed, and the threaded outer end 3 turned into threaded engagement with the socket 5 in the body 4 of the brus In this instance the cap may be pushed on and applied over the broken threaded end 2' substantially as indicated in Fig. 4, so that when the stick is reversed the cap at the outer end when the handle is used will be as indicated in Figs. 1, 2 or 4.

While I have shown a brush with a body 4 of wood with threaded sockets, it is obvious that any mop or brush with a coiled or metal threaded spring socket will engage either threaded end of the handle in the same manner. Inasmuch as spring or metal threaded type sockets are in common use, it is considered unnecessary to illustrate a brush or mop with such a type of socket.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.

What I claim as new Patent is:

l. A cleaning instrument handle, comprising an elongated body and a cap member, said body having each of its ends provided with an axially outstanding screwthreaded neck having a diameter less than the transverse dimension of said body, and said cap member being adapted for application to the neck at either end of the body, said cap member being formed of yieldable material and provided with an axial longitudinal bore closed at one end by a crown which provides a hand-contacting end for the cap member, said bore having respective intercommunicating portions of two diameters, with the portion of lesser diameter lying adjacent to said crown and its wall being complemental to and adapted for frictional engagement with the screwthreads of either of said necks, and the portion of greater diameter extending through the end of the cap opposite to said crown and being complemental to the transverse dimension of the handle body and its wall being adapted for frictional engagement with the portion or" said body adjacent to either of said necks.

2. A cleaning instrument including a handle provided with a cap member, and a cleaning head, said handle comprising an elongated body having each of its ends provided with an axially outstanding screwthreaded neck having a diameter less than the transverse dimension of the handle body, and said cleaning head having a screwthreaded socket adapted to receive and engage either of said screwthreaded necks, said cap member being adapted for application to the neck at either end of the body and being formed of yieldable material and provided with an axial longitudinal bore closed at one end by a crown which provides a hand-contacting end for the cap member, said bore having respective intercommunicating portions of two diameters, with the portion of lesser diameter lying adjacent to said crown and its wall being adapted for frictional engagement with the screwthread of either of said necks, and the portion of greater diameter extending through the end of the cap opposite to said crown and being complemental to the transverse dimension of the handle body and its wall being adapted for frictional engagement with the portion of said body adjacent to either of said necks.

3. A cleaning instrument including a handle provided with a cap member, and a cleaning head, said handle comprising an elongated body having each of its ends provided with an axially outstanding neck having a diameter less than the transverse dimension of the handle body, and said cleaning head having a socket adapted to power of the cap or and desire to secure by Letters receive and engage either of said necks, said cap member being adapted for application to the neck at either end of the body and being formed of yieldable material and provided with an axial longitudinal bore closed at one end by a crown which provides a hand-contacting end for the cap member, said bore having respective intercommunicating portions of two diameters, with the portion of lesser diameter lying adjacent to said crown and its wall being complemental to and adapted for frictional engagement witheither of said necks, and the portion of greater diameter extending through the end of the cap opposite to said crown and being complemental to the transverse dimension of the handle 'body and its wall being adapted for frictional engagement with the portion of said body adjacent to either of said necks.
