Stoddart, Fond du Lac, Wis., assiguor to Bestt Rollr Inc., Fond du Lac, Wis., a corporation of Wisconsin Filed Jan. 10, 1968, Ser. No. 696,798 Int. Cl. B25g 3/30; B44d 3/28 US. Cl. 306-30 3 Claims ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTION Field of the invention This invention relates to frames and handles for paint rollers and the like and particularly to such frames and handles which are adapted to be fitted with an extension, such as a mop stick, so that the operator may use the device on high places without need for ladders, scattolding, etc.

Description of the prior art In the prior practice, as exemplified by US. Patents: 2,984,853, 3,008,167, a manually grasped handle secured to the frame is preferably made of suitable wood or frangible material because such material is cheaper and provides a more secure gripping surface. However, such frangible handles when provided with an internal counterbore in the outer end to receive an extension often split or break when so used.

In the application of Louis Tigerman S.N. 493,520 now Patent No. 3,371,367 and assigned to the same assignee as this application, there is a threaded metal socket which seats in a counterbore in the end of the handle and is directly secured to the solid metal portion of the metal frame to avoid pressure on the walls of the counterbore.

Summary of the invention The essence of this invention is the passing of the handle mounting portion of the metal frame through the frangible handle and rigidly securing to the outer end of such handle mounting portion an internally threaded metal socket which seats against the end of such handle to form a two-part handle. When the extension is fitted in such socket the bending strain due to normal use of the device is absorbed by such metal parts and is not communicated radially to any part of the frangible handle.

BRIEF DESCRIPTION OF THE DRAWING In the drawing:

FIG. 1 is a plan view of a paint roller having a frame and handle embodying the present invention;

FIG. 2 is an enlarged sectional view taken on the line 2-2 of FIG. 1 showing in detail the handle portion of the frame, the frangible handle, and the internally threaded metal socket which forms a part of the handle arranged in accordance with this invention; and

FIG. 3 is an exploded view of the squared outer end of the handle portion of the frame, the inner and outer end of the frangible handle, the internally threaded metal socket forming a part of the handle with a square open- "ice ing on its inner end, and the fastening means all as shown in FIG. 2.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawing and for purposes of illustrating one application thereof, a metal rod-like frame, indicated generally at 10, and a two-part handle consisting of a frangible handle 24 and an internally threaded metal socket 28 embodying this invention are shown associated with a paint roller 18 of well-known design. The frame, as customary for such use, has a shaft portion 12 which rotatably carries the paint roller 18, or other work performing member, connected by a clearance portion 14 to an ofiset portion 16, from which extends a handle mounting portion 20.

This handle mounting portion 20 is provided with spaced nibs 22 (see FIG. 2) which are staked out from the body of such portion. These nibs engage with the manually grasped frangible handle 24 to prevent its axial displacement and rotation relative to such mounting portion.

The two-part handle consists of a frangible handle 24 and the internally threaded socket 28. The frangible handle 24, which is manually grasped for operation of the device at normal operator heights, in this invention is made of suitable inexpensive wood or other frangible material. Such handles provide a most satisfactory grip for the user and are most acceptable to the trade. However, if such handle is a member of a bending resistance chain of components including an extension for use of the device above normal operator heights, it Will frequently split or break even in normal use. Therefore the handle 24 is provided with a bore 25 extending longitudinally through such handle. The length of the handle mounting portion 20 from the nibs 22 to its outer end 25 and the length of the bore 26 in the handle 24 are proportioned so that when handle 24 is mounted on such portion with the nibs 22 in press fitted embedded engagement with the wall of the bore 26, a square end 27 on the outer end 25 will project slightly beyond the outer end of such bore.

The means for fastening an extension, such as a mop stick (not shown), to the roller carrying frame 10 which will exclude the frangible handle 24 as a component in resisting bending strain during use of the device with an extension, consists of an internally threaded metal socket 28 which has a closed end 29 provided with a square opening 30 through which the square end 27 of the handle mounting portion is fitted. The square end is provided with a threaded hole 31 and a screw 32 is threaded there in to hold the end 29 tightly on the square end 27 and in abutment with the outer end of handle 24. This socket is adapted to demountably receive threaded end of an extension and form a joint therebetween which will resist bending. Thus any flexing due to the bending stress transmitted between the roller 18 and an extension fitted in the socket 28 will be directly resisted by (1) the metal .rod material of the frame 10, (2) the rigid joint between socket 28 and the outer end 25 and outer end of the handle 24, (3) the walls of the metal socket 28, and (4) the extension. The frangible handle 24 is thus not a component in this bending chain and is not subjected to bending stresses which tend to split it. While it is subjected to axial compression this has no tendency to split the handle.

The metal socket 28 may be of die cast metal and has relatively thick walls and a thick closed end 29 to provide adequate strength. Its diameter is the same as that of the frangible handle 24 and thus it forms a small part of such handle. While not essential the closed end 29 may have a slightly raised area 34 which interfits with a corresponding recess in the outer end of the handle 24.

I claim:

1. A frame and handle for a roller or other work performing member comprising:

a frame having a solid metal mounting portion for a handle, said portion having a square projection on its outer end, said projection having threaded means thereon, said portion having laterally projecting nibs;

a frangible handle provided with longitudinally extending bore, said mounting portion extending through said bore with said square projection extending beyond said bore, said nibs being partially embedded in one end face of said frangible handle;

a cylindrical internally threaded metal socket having a closed inner end provided with a square opening through which said square projection extends, said socket closed inner end being in engagement with the other end face of said frangible handle, said socket having an outer open end leading to said internally threaded portion whereby said socket is adapted to be removably attached to an extension; and

means cooperating with said threaded means and engaging the closed inner end of said socket so as to hold said socket closed inner end rigidly on said square projection and in tight abutment with the other end face of said frangible handle.

2. A frame and handle as claimed in claim 1 in which said metal socket has the same outer diameter as said frangible handle to form a small part thereof.

3. A frame and handle as claimed in claim 2 in which the outer end of said frangible handle and the inner end of said socket have complemental interfitting raised area and recess.
