Patent number: 9568076Abstract: An epicycloid planet gear cam that converts rotational movement of a driveshaft into linear movement of an output device is disclosed. An epicycloid planet gear is assembled inside a stationary housing with an internal stationary ring gear. A driveshaft eccentric is connected to a driveshaft. The driveshaft eccentric rotates freely in a mounting hole of the epicycloid planet gear. When the driveshaft rotates, the driveshaft eccentric engages the epicycloid planet gear against the stationary ring gear and causes the epicycloid planet gear to rotate. A cam follower pin attached to an output device is held, via a follower roller ball against a cam track of the epicycloid planet gear. As the epicycloid planet gear rotates, the recessed cam track depth causes the cam follower pin to move up or down thereby moving the output device.Type: GrantFiled: April 30, 2015Date of Patent: February 14, 2017Assignee: Patrick James McGrathInventor: Patrick James McGrath

A cam follower pin attached to an output device is held against a cam track of the epicycloid planet gear. As the epicycloid planet gear rotates, the raised cam track height or the slotted cam track distance from the center of the epicycloid planet gear causes the cam follower pin to move up, down, in, or out thereby moving the output device.Type: GrantFiled: December 3, 2012Date of Patent: June 9, 2015Assignee: MechatronicsAsia EnterpriseInventor: Patrick James McGrath

Patent number: 6745812Abstract: A hypocycloid drive device for adjusting slat angles of a venetian blind includes a housing, a roller, a hypocycloid drive reducer, a tilt cord and a tilt rod. The roller is rotatably mounted in the housing and is rotated by pulling the tilt cord. The hypocycloid drive reducer is coupled to the roller and is used to reduce an angular speed of and rotate the tilt rod. The tilt rod is adapted to change slat angles of the venetian blind. Consequently, volume of the hypocycloid drive device is minimized to accommodate convenient installation of the hypocycloid drive device.Type: GrantFiled: February 24, 2003Date of Patent: June 8, 2004Inventors: Tai-Ping Liu, Patrick James McGrath, Wasyl R. Bodnar

Patent number: 6739373Abstract: A lift control device for a roller shade has a side cover, a roller, a chain retaining wheel, a chain and a follower spool. The side cover has an axle and multiple inner teeth. The roller is rotatably mounted around and is eccentric to the axle. The roller has multiple teeth partially engaging with the inner teeth on the side cover and at least one stub. The chain retaining wheel has an eccentric hole to rotatably receive the roller. The follower spool is attached to the chain retaining wheel and engages with the roller to rotate with the roller. Accordingly, a shade blind connected to the follower spool is actuated in instant when the chain is drawn. The follower spool is kept from rotating even when a large force applied to the follower spool, and the safety of using the roller shade is improved.Type: GrantFiled: March 10, 2003Date of Patent: May 25, 2004Inventors: Tai-Ping Liu, Patrick James McGrath, Wasyl R.

Patent number: 6082542Abstract: A full-depth nestable crate includes a plurality of columns, projections and channels disposed along exterior and interior surfaces of a retainer wall such that a top crate is nestable within a bottom crate in a first position and stacked on top of a bottom crate when rotated 180.degree. to a second position with respect to the bottom crate. A plurality of stacking rings depend from the bottom floor and interlock a top crate with a bottom crate when crates are stacked or nested. Each stacking ring is aligned with a pocket in the crate and disposed over a bottle in a bottom crate. A bottle cap on the bottle seats within a depression formed in the stacking ring.Type: GrantFiled: August 28, 1998Date of Patent: July 4, 2000Inventors: Patrick James McGrath, Robert C. Allabaugh, Jr.

Patent number: 6047844Abstract: A nestable crate for bottles having an upright retainer wall surrounding a horizontally disposed floor. The retainer wall has an upper portion, a lower portion, a vertically disposed interior surface and an exterior surface. A plurality of tangency pads are integrally formed in the upper portion of the retainer wall of its interior surface. A nesting window is formed in the interior surface of the retainer wall below each tangency pad. The crate accommodates both single bottles placed in the crate separated as well as bottle-filled cartons.Type: GrantFiled: May 14, 1998Date of Patent: April 11, 2000Assignee: Alpha Holdings, Inc.Inventor: Patrick James McGrath

Patent number: 6021913Abstract: The tray has an outer rectangular panel that has two opposing end walls and two side walls. A plurality of rows of the cells extend from one end panel to the other, intermediate the side panels. Gaps are formed in the outer panel adjacent some of the cells to expose the can labels or UPC codes. The outer panel has a flat surface so advertising may be placed on the outer panel.Type: GrantFiled: December 17, 1996Date of Patent: February 8, 2000Inventor: Patrick James McGrath

Patent number: 5896992Abstract: A bakery tray having a substantially rectangular floor has a retainer wall extending along a periphery of the floor. The retainer wall includes a front wall opposing a rear wall, and a first side wall opposing a second side wall. Two feet are spaced apart horizontally on the first side wall, and two feet are horizontally spaced apart on the second side wall. A first pair of nesting pockets are disposed along the exterior surface of the first side wall above the feet on the same wall; and a second pair of nesting pockets are disposed along an interior surface of the second side wall above the feet on the same wall. When bakery trays of a like configuration are stacked, the feet on the first side wall of a top tray seat within the nesting pockets on the second side wall, and the feet on the second side wall seat within the first nesting pockets on the first side wall of a bottom tray.Type: GrantFiled: June 9, 1998Date of Patent: April 27, 1999Assignee: Alpha Holdings, Inc.Inventor: Patrick James McGrath
