Patent number: 10228043Abstract: In one aspect, a vibratory tool is provided for driving a plurality of rivets out from bores of a guide block into an underlying conveyor belt. The tool has a body, a hydraulically operated main drive rod mounted to the body, and a driver aligned with the main drive rod and slidably mounted to the body. The driver has a plurality of elongated drive rod members for engaging and simultaneously driving multiple rivets out of the guide block bores. The driver has an intermediate impact surface for being impacted by the main drive rod impact end as the main drive rod impact end rapidly reciprocates between retracted and extended positions. The driver also has a rearwardly extending spacer wall for axially spacing the driver intermediate impact surface and the main drive rod impact end in the retracted position thereof by at least a predetermined axial distance sized for optimizing energy transfer from the main drive rod to the driver.Type: GrantFiled: March 27, 2015Date of Patent: March 12, 2019Assignee: Flexible Steel Lacing CompanyInventors: Pan Yim Ng, David A. Lotarski, Ahmed Mohamed Nagib Mohamed Elmetwaly Elmekawy

Patent number: 9157502Abstract: A belt fastener applicator tool and method are provided. The tool is very simple and provides a low cost tool for applying staple belt fasteners to belt ends. The applicator tool includes a plate body having both anvil and comb portions that are fixed thereto so as to be integrated therewith. In one form, the tool has a one-piece construction so that the plate body and anvil and comb portions are integrally formed together. Preferably, the comb portion includes upstanding comb locating members for receiving hinge loops, and the anvil portion includes both initial set anvil wells on one side of the locating members and a final set flat surface portion on the other side of the locating members. The same tool is used for both initial set and final set staple leg setting operations by turning the tool around with an operator using a hammer for staple setting operations.Type: GrantFiled: January 3, 2012Date of Patent: October 13, 2015Assignee: Flexible Steel Lacing CompanyInventors: Virgil Layne Hagie, Pan Yim Ng, Mark Stevenson

Patent number: 8789252Abstract: An apparatus and method for applying staple belt fasteners to conveyor belts are provided that allow staple belt fasteners to be installed on an end of the belt with the use of a single applicator tool and such that all of the staples of the fasteners in the tool are first initially set and then are finally set. In one form, the apparatus has a base with an anvil mounted thereto with the anvil having both initial and final set portions. The belt fastener applicator tool provides for relative shifting of the anvil and a guide device having through openings to align either the initial or final set portions of the anvil with the guide device through openings. The guide device through openings are preferably configured to receive a staple drive member therein.Type: GrantFiled: July 26, 2011Date of Patent: July 29, 2014Assignee: Flexible Steel Lacing CompanyInventors: Pan Yim Ng, Kenneth J. Bargo, William R. Wawczak, Gregory Westphall

Patent number: 8151432Abstract: A system of splicing ends of conveyor belts is provided that enables a splice installer to install splices in an easy and fast manner. In one aspect, the system includes a base having a recess extending therealong configured to fit fastener members of conveyor belt fasteners therein so that the fastener members do not shift as the belt fasteners are attached to the belt ends. In another aspect, removable rivet guide blocks are provided which significantly reduces the weight of an alignment bar having upper plate members of the belt fasteners secured thereto. In addition, the removable guide blocks allow the installer to secure the upper plate members to the alignment bar without having to deal with the heavy weight of multiple guide blocks fixed thereto. A method of splicing belt ends is also provided which includes indexing the removable guide block along the alignment bar during for riveting operations.Type: GrantFiled: March 10, 2008Date of Patent: April 10, 2012Assignee: Flexible Steel Lacing CompanyInventors: William J. Daniels, William R. Wawczak, Pan Yim Ng
