Patent number: 6872161Abstract: A modular gear system for transmitting power from a motor to a device such as a pump which requires power to operate. The system includes a gearbox and first and second planetary gearset assemblies connectable between an output shaft of the motor and a drive shaft of the pump. The system may be configured as either a single-stage mode wherein the first gearset assembly is received in the gearbox to produce a rotational speed adjustment between the shafts, or a multi-stage mode wherein both the first and second gearset assemblies are received in the gearbox and are connected in series to produce a different rotational speed adjustment. The system provides flexibility for different speed and power requirements and is adaptable to a variety of motors.Type: GrantFiled: March 28, 2003Date of Patent: March 29, 2005Assignee: Lincoln Industrial CorporationInventor: Leonard J. DiCarlo

Patent number: 5868224Abstract: An adaptor for generally permanent coupling of a lubricant line to a lubricant fitting. The fitting has a base, a neck, a head, a lubricant passage, and a valve member biased toward a closed position. The adaptor comprises a body having a hole extending therethrough and an insert in the hole having a circular head and a thin-walled cylindrical extension extending from the head slidable in the hole. The extension defines a socket for receiving the head of the fitting on application of the body and insert to the fitting. The extension is radially inwardly deformable into interlocking engagement with the fitting. The head of the insert has a pin extending therefrom within the socket in the direction toward an inner end of the hole. The head includes a passage for flow of lubricant therethrough.Type: GrantFiled: June 24, 1997Date of Patent: February 9, 1999Assignee: McNeil (Ohio) CorporationInventor: Leonard J. DiCarlo

Patent number: 5525137Abstract: A method for producing bas-relief stained glass comprises the steps of providing glass ground to a powder. The powdered glass is mixed with a vehicle to produce a paste which is applied to a sheet of glass. The applied layer of paste forms a design on the sheet of glass and has a raised appearance relative to the sheet of glass. The sheet of glass is heated for a period of time at a temperature high enough to bond the powdered glass paste to the sheet of glass, but low enough to prevent permanent deformation of the sheet of glass and to maintain the design formed by the paste on the sheet of glass.Type: GrantFiled: October 14, 1993Date of Patent: June 11, 1996Assignee: Leonard DiCarloInventor: Leonard J.

Patent number: 5465646Abstract: An improved hydraulic motor includes a cylinder having a head end and a rod end, and a piston reciprocable in the cylinder dividing it into a first expansible chamber toward the head end and a second expansible chamber toward the rod end. Fluid under pressure from a supply source is continually delivered to the second chamber. A fluid directional valve controls the delivery of fluid to and exhaust of fluid from the first chamber for reciprocating the piston within the cylinder. The piston has valving associated therewith for controlling the operation, in conjunction with a relay valve, of the fluid directional valve.Type: GrantFiled: February 23, 1994Date of Patent: November 14, 1995Assignee: McNeil (Ohio) CorporationInventor: Leonard J. DiCarlo

Patent number: 5349895Abstract: An improved runaway control for an air motor operable on increase in speed of the air motor above a speed limit stop the motor. The control includes a pressure-responsive device having an air chamber for air under pressure. Further provided is a movable member which moves away from a first position in response to increase in air pressure in the chamber above a predetermined limit to a second position, and movable back to the first position on reduction of pressure in the chamber below the limit. The movable member, when in its first position, enables the operation of the air motor, and when in its second position, cuts off the operation of the motor. An air pump is interconnected with the air motor for operation simultaneously with the motor for delivering air under pressure at a rate related to the speed of the motor to the chamber.Type: GrantFiled: November 23, 1992Date of Patent: September 27, 1994Assignee: McNeil (Ohio) CorporationInventor: Leonard J. DiCarlo
