Patent number: 11952019Abstract: A steering mechanism for a rail vehicle includes two steering arms, each including a pair of support arms that have a joining component with a recess. The two steering arms are articulated in a manner that maintains a minimum separation between the steering arms so that the arms can rotate relative to one another. The minimum separation is maintained by an insert that installs into the joining component recesses components of each of the steering arms. The insert has two sides, each side having a flexible material and forming a shape that mates with the recess. The insert provides resistance to the rotation between the first and second steering arms, and the resistance depends on the stiffness of the flexible material of the insert.Type: GrantFiled: January 24, 2022Date of Patent: April 9, 2024Assignee: ADVANCED TRUCK SYSTEMS CORP.Inventors: John Rudibaugh, Manuel Tavares, Wayne Murphy, Perry Levitt

Patent number: 11433927Abstract: The sideframe and bolster of a railway car truck are constructed such that basic overall sideframe and bolster appearance is maintained, but the actual material it is constructed of is changed. The material used is changed from cast steel to an austempered metal, such as, cast austempered ductile iron; whereas cast iron has a density, 0.26 lbs/in{circumflex over (?)}3, which is approximately 8% less than steel, 0.283 lbs/in{circumflex over (?)}3. This immediately allows for a reduction in weight. A second benefit is that iron is easier to pour than steel and actually increases in volume, slightly, as metal cools compared to steel which shrinks. Efficient use of materials is improved, meaning less metal is used to make the same final shape, as a way of reducing the sideframe and bolster weight. Both factures combined allow for a lighter weight railway car truck, sideframe and bolster, while utilizing standard designs.Type: GrantFiled: April 8, 2019Date of Patent: September 6, 2022Assignee: Pennsy CorporationInventors: Manuel Tavares, Aaron Stern, Michael J.

Patent number: 11345372Abstract: Lightweight yokes are provided. According to some embodiments, the basic overall appearance of the yoke may be maintained, but the actual material of which it is constructed is changed. According to other embodiments, the yoke is provided with an improved lightweight construction, and, yet other embodiments the yoke may be provided with an improved construction and formed from a preferred material. Yokes may be constructed from cast austempered ductile iron; whereas cast iron has a density, 0.26 lbs/in{circumflex over (?)}3, which is approximately 8% less than steel, 0.283 lbs/in{circumflex over (?)}3, thereby allowing for a reduction in weight over steel. A suitable austempering process is used to produce the austempered metal yoke. Yokes have improved configurations which may require less metal to produce the yoke. Both, the lightweight material and improvements in configuration of the yoke structure may combine to provide a lighter weight yoke.Type: GrantFiled: April 9, 2019Date of Patent: May 31, 2022Assignee: Pennsy CorporationInventors: Aaron Stern, Zachary Ryan Brook, Manuel Tavares, Wayne H.

Patent number: 11345374Abstract: The coupler system of a railway car truck is constructed such that basic overall appearance may be maintained, but the actual material of which it is constructed is changed. According to one embodiment, the coupler is constructed from cast austempered ductile iron; whereas cast iron has a density, 0.26 lbs/in{circumflex over (?)}3, which is approximately 8% less than steel, 0.283 lbs/in{circumflex over (?)}3, thereby allowing for a reduction in weight over steel. A suitable austempering process is used to produce the austempered metal coupler and components thereof. A second benefit of embodiments of the present invention provides for a more efficient use of materials, meaning less metal is used to make the same final shape, as a way of reducing the coupler weight. Both factures combined allow for a lighter weight coupler, while utilizing the standard designs. Alternate coupler configurations are disclosed for further reducing coupler weight.Type: GrantFiled: April 8, 2019Date of Patent: May 31, 2022Assignee: Pennsy CorporationInventors: Aaron Stern, Manuel Tavares, Zachary Ryan Brook, Michael J.

Patent number: 10994754Abstract: A coupler having a support provided through the body of the coupler and a plurality of openings in the coupler which are configured as open cavities. The coupler structure includes a shank that has a vertical support as well as lateral support. The coupler may be configured with a double I-beam structure with openings into the shank. Cores that may be fixed to the mold may be used to form the coupler and produce the openings in the shank.Type: GrantFiled: December 10, 2018Date of Patent: May 4, 2021Assignee: Pennsy CorporationInventors: Aaron Stern, Perry Levitt, Manuel Tavares, Zachary Ryan Brook, Wayne H.

Patent number: 10906567Abstract: A process for producing a coupler knuckle and an improved coupler knuckle design are provided. The process produces a coupler knuckle by constructing a mold having the shape of the coupler knuckle. The mold is coated with a material that is resistant to melting at the molten melt temperatures of the molten metal used to form the knuckle. With the mold coated, the cavities in the mold interior are filled by placing an inert material therein. The molten metal used for forming the knuckle contacts the mold and consumes it, while the coating serves to provide a shape for the knuckle.Type: GrantFiled: September 2, 2019Date of Patent: February 2, 2021Assignee: Pennsy CorporationInventors: Zachary Brook, Manuel Tavares

Publication number: 20200362597Abstract: A locking mechanism for sliding doors and windows includes a lock with a lock cylinder having a key hole for the key. The lock includes a tab and a cylinder pin. The locking mechanism further includes a toggle box, a track, a stopper, a chamber and an operating latch, a blocking toggle, an operating handle and left and right side faces. The key includes a key shaft, key head, a bore, an inlet and key teeth. The abutment of the cylinder pin on the stopper promotes the blocking in the locking mechanism which presents reduced dimensions for application in modern design frame structures.Type: ApplicationFiled: April 22, 2020Publication date: November 19, 2020Applicant: JOFEBAR S.A.Inventor: António Manuel TAVARES NUNES

Patent number: 10570244Abstract: A process for forming a cross-linked thermoplastic elastomer is disclosed herein. The cross-linked thermoplastic elastomer is a thermoplastic cross-linked copolyester and is preferably formed by heating a first mixture containing a thermoplastic elastomeric base material, a monomeric diisocyanate comprising between 1 to 10% of the total weight of the first mixture, and a second mixture of a first diamine and a second diamine comprising between 1 to 10% of the total weight of a total reaction product. The heated first mixture, which is flowable, is injected into at least one injection molding device, with the second mixture injected at predetermined intervals to create a homogeneous reaction product. The reaction product may be injected into a mold to produce articles.Type: GrantFiled: August 9, 2012Date of Patent: February 25, 2020Assignee: Pennsy CorporationInventors: Manuel Tavares, Michael J.
