Patent number: 9267624Abstract: A bracket stores and separates conduits. The bracket includes two interchangeable halves having an engagement extrusion extending from an inner face. Each half has a corresponding receptive slot disposed in the inner face. The bracket half includes at least one conduit receptive channel defined in the inner face. The halves align and engage when each half's extrusion is inserted into the other half's slot. The channels align to secure a conduit therein. The engagement portions define a dovetail and socket engagement. At least two stages of securement may be provided. Securement may comprise snap fit, sliding or other methods. A first, temporary stage of engagement initially joins the halves, adjustably and releasably retaining the halves and the conduits together. The second and subsequent stages of engagement are tighter engagements between the tail and socket, achieved by applying more pressing force to the halves or inserting a fastener.Type: GrantFiled: April 21, 2014Date of Patent: February 23, 2016Assignee: Gates CorporationInventors: Layne Railsback, Walker Bolger, Donald R.

Patent number: 9194458Abstract: The durability of a frictional power transmission belt is improved. A V-ribbed belt (10) comprises an adhesion rubber portion (12) and a compression rubber portion (14) provided below the adhesion rubber portion (12).
