March 5, 1968 TIGERMAN HANDLE FOR PAINT ROLLER Filed Oct. 6, 1965 (NVENTOR Lows T\6ERM\N ATTORNfiY United States Patent Otllice 3,371,367 HANDLE FQR PAiNT RQLLEIR Louis Tigermau, Milwaukee, Wis assignor to llestt Rotter End, Fond du Lac, Wis, a corporation of Wisconsin Filed Get. 6, i965, Ser. No. 493,526 4 Eilaims. (Ql. 115-145) ABSTRAQT @F THE DISCLGSURE This invention comprises a metal frame for a paint roller or the like which has a solid metal portion on which a frangible handle is carried. The solid metal portion extends through such frangible handle and an internally threaded metal socket is rigidly secured to the end of such solid portion. When an extension is fitted in such socket the strain is transmitted directly to such metal portion and not to such frangible handle.

This invention relates to frames and handles for paint rollers and the like and particularly to such frames an handles which are adapted to be fitted with an extension, such as a mop stick, so that the operator may use the evice on high places without need for ladders, scaffolding, etc.

The 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 internally threaded counterbore to receive an extension often split or break when so used.

It is the object of this invention therefore to provide a frame and frangible handle for a paint roller or the like which can be attached to an extension and used without applying pressure to the frangible handle tending to split This object is accomplished by passing 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. 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 in any appreciable manner to the frangible handle. Thus, there is no tendency to split such handle. in order to have neater appearance and to shield such metal socket from dripping paint, etc., the outer end of the fran ible handle may be counterbored or recessed to receive such socket. However, since the walls of such socket absorb the bending stresses, they will not be communicated to the wall of the recess in sufficient degree to cause splitting of the frangible handle.

Other objects and advantages will be pointed out in or be apparent from the specification and claims, as will obvious modifications of the single embodiment shown in the drawings in which:

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 22 of FIG. 1 showing in detail the handle portion of the frame, the threaded metal socket, and the frangible handle arranged in accordance with this invention;

FIG. 3 is a top end view of FIG. 2;

FIG. 4 is a bottom end view of FIG. 2; and

FIG. 5 is an exploded view of the outer end of the handle portion of the frame, the outer end of the frangible handle, the threaded metal socket, the reinforcing spot weld plate and the protective ferrule shown in FIG. 2.

Referring to the drawings and for purposes of illustrating one opplication thereof, a metal rod-like frame,

Patented Mar. 5, 1568 indicated generally at fill, and a frangible handle 24 embodying this invention are shown associated with a paint roller 1% 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 offset portion 16, from which extends a handle mounting portion 26.

This handle mounting portion 26 is provided with diametrically spaced nibs 22 (see FIG. 2) which are staked out from the body of such portion. These nibs engage with the manually grasped handle to prevent its axial displacement and rotation relative to such mounting portion.

A handle 24;, which is manually grasped for operation of the device at operator heights or below, in this inven tion 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 operator heights, it will frequently split or break even in normal use. Therefore, the handle 2 is provided with a bore 26 extending longitudinally through such handle. The length of the handle mounting portion 2d 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 tribe 2 2 in press fitted embedded engagement with the Wall of the bore 26, 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 llll 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 rigidly attached to the projecting end 25 of the handle mounting portion. This socket is adapted to demountably receive a threaded end of an extension and form a joint therebetween which will resist bending. Thus, any flexing due to 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 iii, (2) the rigid joint between socket 255 and the outer end 25, (3) the walls of the metal socket 23, and (4) the extension. The frangible handle 24 is thus not a component in this chain and is not subjected to bending stresses which tend to split it.

In order to make a rigid joint between the socket 28 and the outer end 25, the closed end wall 29 of the socket is spot welded to such outer end after the handle is fitted on the portion and pressed into embedded engagement with nibs 22. This joint may be strengthened and its rigidity enhanced by placing a metal plate 39 against the inside of the closed end wall 2% and including it in the spot weld. The spot weld will then extend from this disc through such closed end wall to the outer end 25 thus forming an increased bend resisting section without necessitating an increase in the thickness of the closed end wall 29. Thus, such socket may be of uniform thickness and inexpensively made as a formed metal part.

To enhance appearance and to protect the socket from contact with paint and the like, the end of the handle 24 may project beyond the end of the bore 26 and be provided with a recess or counterbore 32 which is axially alined and connected with the bore 26. This recess is deep enough and of suflicient diameter to fully receive the socket 255 as shown in Pl'G. 2. However, since the walls of such metal socket absorb the stress resulting from the normal use of the roller when attached to an exten- 3 sion, such stress will not be transmitted to the wall of the recess in sufiicient degree to split it.

More as a matter of decoration and protection for the exposed outer end of the frangible handle 24, there may be snuggly fitted on such end a metal ferrule 34 in the manner well known in the art.

Although but one embodiment of the present invention has been illustrated and described, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention or from the scope of the appended claims.

What is claimed as new is:

1. A frame for a roller or other work performing member having,

a solid metal handle mounting portion with an outer end, said handle having laterally projecting nibs,

a frangible handle provided with a longitudinally extending bore, said mounting portion extending through said bore with said outer end projecting beyond said bore, said nibs being partially embedded in said frangible handle, and

an internally threaded metal socket having a closed inner end rigidly secured to said outer end and in engagement with 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.

4 2. A frame as claimed in claim 1 in which said frangible handle has a recess in the outer end thereof connected with said bore, and said socket is positioned within said recess. 5 3. A frame as claimed in claim 1 in which said socket has its closed end spot welded to said outer end. 4. A frame as claimed in claim 3 in which there is a metal plate positioned on the face of said closed end,

10 said plate being spot welded to said closed end and said outer end to provide a more rigid connection between said handle mounting portion and said socket.
