Abstract

Abstract A paint brush having a ball-and-socket connection between its head and handle. The handle has a ball configuration at one end which fits into a socket in the base of the brush head to form the ball-and-socket connection. The base of the head is fitted with a wing nut having a concave forward end designed to fit congruently against the surface of the ball. The wing nut can be moved into and out of tight contact with the ball by hand. This permits universal adjustment of the head, with respect to the handle, and locking of the head in any position of adjustment.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 308 words
Universally adjustable brush means primarily suitable for paint brush utility comprising, in combination: a handle with a ball configuration at one end; and brush head means of generally flattened configuration having a base portion with a receptive socket for said ball configuration, said socket serving to receive said ball configuration and thereby form a ball-and-socket joint between said handle aNd said brush head means; and including adjustable means for fastening the handle and brush head means rigidly together; said brush head means comprising a plurality of bristles fixedly secured at their inner ends in a suitable mounting and said base portion, the mounting for the bristles and the base portion being retained in back-to-back adjacency by means of a metal ferrule, and the receptive socket for said ball configuration in said base portion being accessible to said handle, to permit the formation of said ball-and-socket joint between the handle and said brush head means, at the center of the bottom of said base portion; said base portion being formed from two suitably shaped bodies of a material of adequate strength and toughness for the purpose, said bodies being arranged with a surface of each in contact with, and cemented to, a similarly shaped surface of the other, and having facing concavities in said contacting surfaces shaped to form said socket for the ball configuration of said handle; all parts of said brush head means cooperating to permit universal adjustment of said brush head means relative to said handle so that the brush means can be used in a form similar to that of conventional paint brush means of the straight handle type, or in any of a variety of forms in which the brush head means is tilted to permit usage of the brush means in spaces too cramped for such usage of said conventional paint brush means.
Claim 2
Dependent Claim 308 words
Universally adjustable brush means primarily suitable for paint brush utility comprising, in combination: a handle with a ball configuration at one end; and brush head means of generally flattened configuration having a base portion with a receptive socket for said ball configuration, said socket serving to receive said ball configuration and thereby form a ball-and-socket joint between said handle aNd said brush head means; and including adjustable means for fastening the handle and brush head means rigidly together; said brush head means comprising a plurality of bristles fixedly secured at their inner ends in a suitable mounting and said base portion, the mounting for the bristles and the base portion being retained in back-to-back adjacency by means of a metal ferrule, and the receptive socket for said ball configuration in said base portion being accessible to said handle, to permit the formation of said ball-and-socket joint between the handle and said brush head means, at the center of the bottom of said base portion; said base portion being formed from two suitably shaped bodies of a material of adequate strength and toughness for the purpose, said bodies being arranged with a surface of each in contact with, and cemented to, a similarly shaped surface of the other, and having facing concavities in said contacting surfaces shaped to form said socket for the ball configuration of said handle; all parts of said brush head means cooperating to permit universal adjustment of said brush head means relative to said handle so that the brush means can be used in a form similar to that of conventional paint brush means of the straight handle type, or in any of a variety of forms in which the brush head means is tilted to permit usage of the brush means in spaces too cramped for such usage of said conventional paint brush means.
Claim 3
Dependent Claim 95 words
Brush means in accordance with claim 1 in which said adjustable means for fastening the handle and brush head means rigidly together comprises a tapped opening running into said brush head means to communication with said socket in its base portion, and restrictive cooperating setscrew with a concave end sized for threaded engagement with the tapped opening, the concave end of said setscrew being shaped for congruent interfit with the surface of said ball configuration, whereby tightening of the screw against the ball configuration serves to rigidly secure said brush head means to said handle.
Claim 4
Dependent Claim 38 words
Brush means in accordance with claim 2 in which said setscrew is a wing nut, whereby manual adjustment of said brush head means to various positions of use, and locking of the latter in such positions, is facilitated.
Claim 5
Dependent Claim 78 words
Brush means in accordance with claim 3 in which said handle has a relatively thin neck segment separating said ball configuration from its main portion, and the access opening to said socket in said base portion of said brush head means is sufficiently restricitve to prevent the passage of said ball configuration, and has a beaded rim to permit maximum tilting of said brush head means relative to said handle during adjustment of said brush means for use.
Claim 6
Dependent Claim 19 words
Brush means in accordance with claim 4 in which said handle of said brush means is made of nylon.
