  • Patent number: 4908952
    Abstract: An alignment and support device for tiles having a generally wedge-shaped rectangular body which tapers from a rear edge to a front edge thereof. The rear edge of the device is reinforced by a generally U-shaped ridge which is coextensive with the rear edge and portions of the side edges thereof. The reinforcement ridge aids the user in gripping the device for placement and removal. Ridge members may also be included on the surface of the device extending from the reinforcement ridge to the front edge thereof for increasing the overall thickness and rigidity of the wedge so that it can be used for spacing larger tiles and/or marble slabs. In another embodiment of the device, the retaining ridge is simplified to extend along only the rear edge of the wedge. Such a modification allows the device to be used on smaller tiles where greater reinforcement is not required.
