Publication number: 20160257025Abstract: The invention relates to a device and to a method for artificially ageing stone blocks, in particular concrete blocks, clinker bricks and natural stone blocks. Provided is an ageing duct which comprises a base, an upper boundary and lateral boundaries. In addition, a vibration device is provided in order to make at least the base of the ageing duct vibrate. In addition, a feed device is provided in order to push at least two rows of stone blocks, which are arranged side by side in the feed direction and are formed in each case by several stone blocks placed one behind the other, through the ageing duct, wherein the stone blocks of the rows of stone blocks are placed in such a manner on the base of the ageing duct that the stone block surface of the stone blocks to be treated is aligned transversely with respect to the feed direction.Type: ApplicationFiled: October 13, 2014Publication date: September 8, 2016Applicant: Baustoffwerke Gebhart & Soehne GmbH & Co. KGInventors: Hans Gebhart, Manfred Staehle

Patent number: 9061438Abstract: Device for the artificial aging of stones with at least an aging channel arranged on a support, a vibration device to set the support in motion, and a conveying device to move the stone through the aging channel. The aging channel has at least a first and a second impacting surface, which apply the aging effect to the stone. The aging channel comprises at least two sections, wherein the stone moves through a first section in a first feed direction and wherein a second section runs at an angle to the first section, so the stone is deflected in its feed direction to move into a second feed direction.Type: GrantFiled: October 16, 2012Date of Patent: June 23, 2015Assignee: Baustoffwerke Gebhart & Soehne GmbH & Co. KGInventors: Hans Gebhart, Manfred Staehle

Patent number: 8696341Abstract: The invention relates to a device for producing concrete blocks, particularly paving stones, building blocks or the like, comprising a storage container forming a receiving chamber for a plurality of layers of concrete in different colors. Dispensing means are provided, in order to dispense partial amounts of the layers from the receiving chamber such that a release device connected downstream receives a mixture of the layers of concrete in different colors. At least a partial section of a side wall of the receiving chamber is provided with at least one dispensing opening for dispensing a partial amount of the layers. The size of the passage of the dispensing opening can be varied by the dispensing means.Type: GrantFiled: January 28, 2009Date of Patent: April 15, 2014Assignee: Baustoffwerke Gebhart & Soehne GmbH & Co. KGInventors: Manfred Staehle, Hans Gebhart
