Patent number: 11148108Abstract: A paint multi-tool assembly includes a shaft that has a hooked end that is insertable into a power tool thereby facilitating the shaft to be rotated when the power tool is turned on. A first cylinder insertably receives the shaft thereby facilitating the first cylinder to be inserted into an open end of a paint roller. Thus, the power tool can rotate the paint roller for cleaning paint off of the paint roller. A plurality of fins is each coupled to and extends away from the first cylinder for stirring paint in the paint container. A second cylinder is coupled to each of the fins such that the second cylinder is spaced from the first cylinder. In this way the second cylinder can be inserted into the paint container or be inserted into the open end of the paint roller.Type: GrantFiled: July 24, 2019Date of Patent: October 19, 2021Inventor: Aaron Hedgecock

Patent number: 7900488Abstract: In connection with the non-destructive stretching and fastening of pelts (2) on distention elements/pelt boards (4), where the pelt is stretched and fastened in the stretched position during the drying process by means of a fixing bag, it has shown that the pelts give way (shrink) on each side of the tail root of the pelt, with the result that use is made of a number of staples for the fastening of these places on the stretched pelt. Since it is not at all desirable to use staples, a development of the pelt boards (4) has taken place, so that these have an arched extent around two transverse axes in relation to their longitudinal axes. Moreover, it has long been desirable to be able to stretch the pelts to a greater degree, which has not been possible with the use of the known stretching machines.Type: GrantFiled: September 20, 2004Date of Patent: March 8, 2011Assignee: Dansk Mink Papir A/SInventor: Jens Hedegaard

Patent number: 7784312Abstract: In connection with the various working operations in the production of furs, a not inconsiderable amount of manual labor is involved in the handling of the pelt boards or expansion pelt boards between the various work processes. To make the production of furs more profitable, manual labor is reduced to a minimum using a device for performing a complete or partial emptying/filling of a drying aggregate for upstanding expansion pelt boards, with or without tanned, or tanned and dried pelts, to one or more suitable receiving stations for further transport and/or handling. The device has a gripping element which can be activated for displacement, the movements of which are controlled by a control unit so that upstanding expansion pelt boards with or without tanned, dried pelts, are transferred automatically in upstanding position from the surface of the drying aggregate to a receiving point for further handling and transport.Type: GrantFiled: January 23, 2007Date of Patent: August 31, 2010Assignee: Dansk Mink Papir A/SInventor: Jens Hedegaard

Patent number: 5868798Abstract: A process and apparatus for treating animal skins or hides (10) comprises stretching the hide to extend it and to open the structures and mounting the hide in a frame (15) by ties (12) extending between the hide edge attachments (11) and the frame. The hide (10) while in the frame. The hide (10) while in the frame passes through multiple process operations involving sequentially applying treatment fluids under pressure. A pressure differential maintained across the hide thickness enables the fluids to pass through the flesh surface (10a) and emerge from the grain surface (10b). The hide (10) can be supported on a porous backing membrane (45) during treatment. The treatment fluids are collected and processed for recycling, recovery of by-products and disposal.Type: GrantFiled: February 24, 1997Date of Patent: February 9, 1999Assignee: Tanning Technologies Pty LtdInventors: Colin Charles Anderson, Yuri Ronald Obst, Brian Waters
