Filed:

Mar 28, 1983

Appl. No.:

6/479633

Inventors:

John T. Potter - Locust Valley NY

Assignee:

Iquad Company Incorporated - Locust Valley NY

International Classification:

B41J 132

US Classification:

4001411

Abstract:

A typewriter printing assembly is disclosed in which a typing assembly and type actuator are mounted for movement along a shaft and are connected to a follower. The connection of the typing assembly and follower is a detachable one, and the support for the shaft is removable for facile assembly and disassembly of the typing assembly on the shaft. The type actuator comprises a light interfitting assembly of the type hammer and support formed to accommodate the shaft and for straight line movement of the hammer when activated.

Appl. No.:

6/310189

Inventors:

John T. Potter - Locust Valley NY

Assignee:

Iquad Company Incorporated - Locust Valley NY

International Classification:

F16H 118
F16H 2702
F16H 120

US Classification:

744248R

Abstract:

A lead screw and follower assembly employs a specially formed helical thread and a follower assembly employing bearings which ride on the several surfaces of the helical thread, thereby providing essentially frictionless motion and also preventing deflection of the lead screw during operation. The lead screw is preferably formed of a synthetic material such as polycarbonate incorporating glass fibers and the bearings are either roller or ball bearings.

Appl. No.:

5/522223

Inventors:

John T. Potter - Locust Valley NY

Assignee:

Potter Instrument Company, Inc. - Plainview NY

International Classification:

B63B 4100

US Classification:

114141

Abstract:

The hydraulic system for raising and lowering a heavy keel comprises a cylinder, a piston movable in the cylinder and connected to the keel, and an accumulator for supplying hydraulic fluid at a positive pressure below that necessary to raise the keel against the piston in a direction for raising the keel. A hand pump is provided for supplying hydraulic fluid at a pressure great enough to overcome the weight of the keel. A valve allows the hydraulic fluid to flow either to or from the cylinder. An enlarged flow line communicates the accumulator with the cylinder so that if an external force should cause the keel to raise suddenly, hydraulic fluid would flow rapidly beneath the piston. A gas is provided on the other end of the piston for providing a cushioning effect and restricting the speed at which the keel can be raised. A restricted flow valve is provided in the system for regulating the speed at which the keel can be lowered.

Appl. No.:

6/407841

Inventors:

John T. Potter - Locust Valley NY

Assignee:

Iquad Company Incorporated - Locust Valley NY

International Classification:

B41J 110
B41J 154

US Classification:

4001411

Abstract:

Printing apparatus for printing characters in a line on paper has a print drum arranged horizontally with respect to the paper and is formed having the indexing means and the translational drive means affixed to the frame to greatly decrease the mass of the assembly. An actuator is arranged inside the print drum and a hammer arm extends at a 45. degree. angle up and into the print drum to contact the actuator thereby driving a selected character outward into contact with the paper. The print drum includes rings having T-shaped characters slidably retained therein in a radial fashion. The characters are retained in the ring by means of a unitary elastic band which passes through slots formed in each type carrier.

Appl. No.:

6/476666

Inventors:

John T. Potter - Locust Valley NY

Assignee:

Iquad Company Incorporated - Locust Valley NY

International Classification:

B41J 130
F16H 5518

US Classification:

4001442

Abstract:

A printing mechanism includes a right-angle drive for imparting rotation to a rotary printing element having printing type thereon, rotation of the print element selecting a specific character to be imprinted on a printing medium. The right-angle drive permits the printing element to be moved transversely of the printing medium while receiving rotational mechanical signals for imparting the requisite rotation to the printing element. A shaft having a longitudinal keyway therein passes though a bevel gear of the right-angle drive, there being a key extending from the gear to the keyway to permit the sliding of the gear along the shaft while being controlled in rotation thereabout. A carriage carrying the rotary print element and the right-angle drive is driven in the transverse direction by a worm gear having a worm surface provided with inclined sides which mate with a pair of angled inclined rollers supported by the carriage for engagement with the worm gear. The inclined rollers, the keyway, and a spring forcing together gears of the right-angle drive inhibit any backlash to permit an accurate printing of a message. The foregoing mechanical configuration avoids undue complexity so as to permit rapid operation of the printing mechanism.
