DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a drive attachment device, particularly for enabling rotary drive to be transmitted to a paint brush.
It is well known that paint brushes are difficult to clean because of the quantity of paint soaked up by their bristles and the fact that this penetrates to their roots. Conventionally paint brushes are cleaned by soaking and rinsing in water or some other suitable solvent but this basic method takes a considerable length of time, requires large amounts of the solvent, and even then, may leave paint trapped in the roots.
Attempts have been made to find other, less time consuming methods of removing paint from paint brushes and these have included centrifuging the brushes at high speed about their longitudinal axes. Although this method is more effective than simple soaking and rinsing, apparatus for achieving it has not to date been provided which is sufficiently economical and convenient for widespread use, particularly in the domestic market where such apparatus would be most welcome. It is not, for example, possible for them to be gripped adequately by attachment devices such as chucks of domestic motorised apparatus such as power drills for various reasons: the weight of a paint brush lies in the brush end and to achieve stable rotation of the brush it should be gripped close to the head but chucks in common use would grip the end of the handle remote from the head; paint brush handles are generally irregular in cross-section and cannot be gripped with sufficient force and/or in such a manner by equipment in current general use to maintain them in alignment with the rotational axis; if strong pressure is exerted on a handle to grip it, there is a considerable danger of damage to a paint or varnish layer covering the handle or indeed to the handle itself in view of the fact that it is commonly of wood and can therefore be bruised or dented. Alternative methods of supporting artifacts for rotation by means of two attachments at opposite ends of the artifact are, of course, difficult to apply to paint brushes because of the potential damage to the bristles, the soiling of the attachment at the head end and the difficulty of providing a surrounding casing for catching the centrifuged paint.
An attempt has been made in the prior art to overcome these difficulties, by the provision of an implement for rotating a paint brush to clean it as is shown in UK Patent No. 867,960 comprising a support which can be rotated about an axis and which has a group of resilient fingers which extend generally parallel to the axis and have inwardly turned free ends for gripping a paint brush handle between them. Such equipment is clearly intended to grip the handle relatively close to the brush head but the apparatus as a whole is designed to be rotated manually, that is, not at the high speeds achievable by a motor.
The object of the present invention is to provide an alternative device for enabling an elongate member such as a paint brush handle to be gripped so that rotary drive can be transmitted thereto to rotate it about its axis. Accordingly the present invention provides a drive attachment device comprising a housing defining an axis and adapted to receive drive to rotate it about that axis, the housing having an open end for the axial insertion into the housing of an end portion of an elongate article to which drive is to be transmitted and including means for restraining the inserted end against movement transverse the axis, characterised in that the open end is spanned by at least two resilient gripper members each attached at opposite ends to the housing such that an article must be forced between the gripper members into the housing, the force stretching the gripper members which then grip a part of the article spaced from the inserted end to retain the article in the housing and to transmit rotary drive thereto on rotation of the housing about its axis.
The device of the invention may be used or adapted to attach any elongate member to a drive to rotate it, preferably about its ax
