US Patent:

43745024, Feb 22, 1983

Filed:

May 9, 1978

Appl. No.:

5/904206

Inventors:

George M. Toman - Chicago IL
Thomas J. Bock - Schaumburg IL
Chandrakant Bhatia - Buffalo Grove IL

Assignee:

Union Special Corporation - Chicago IL

International Classification:

D05B 5734

US Classification:

112162

Abstract:

The output centerpoint of a Cardan gear mechanism is connected via a ball and a pin slideable therethrough to a lever which in turn carries a looper. Because the major axis of the lever and the axis swept out by the output centerpoint are skewed the lever is reciprocated back and forth along its own major axis while being rotated therearound. This results in the looper being swept back and forth along part of a generally helical-like path.

International Classification:

D05B 5730
F16H 3712

US Classification:

112220

Abstract:

A Cardan gear assembly wherein rotary input motion of the main shaft is converted to elliptical output at the Cardan gear output centerpoint. The Cardan gear output centerpoint is connected via a ball and a pin slideable therethrough to a support having a work performing instrumentality arranged at its distal end. During operation, the elliptical output motion of the Cardan gear output centerpoint is transmuted into three dimensional, elliptical like motion at the tip of the work performing instrumentality.

Inventors:

Thomas J. Bock - Streamwood IL

Assignee:

Borg-Warner Corporation - Chicago IL

International Classification:

F16G 516

US Classification:

474201

Abstract:

A metal chain-belt for drivingly connecting the pulleys of a pulley transmission, each pulley of which is composed of a pair of flanges, the chain-belt comprising a carrier composed of interleaved sets of links and pulley flange engaging members, each of which is a pair of back-to-back joined C-shaped member, the arms of the latter engaging the pulley flanges. The longitudinal length of the top arms of a pair of members substantially equals the pitch of the chain; the longitudinal length of the bottom arms is less to permit the belt to articulate.

Assignee:

Union Special Corp - Chicago IL

International Classification:

D05B 5736

US Classification:

112200

Abstract:

A Cardan gear assembly wherein rotary input of the main shaft is converted to elliptical output at the output centerpoint. A force transfer means connects the output centerpoint to a means supporting a work performing instrumentality. Thus during operation the work performing instrumentality is driven through an elliptical like curve.

Assignee:

Union Special Corporation - Chicago IL

International Classification:

D05B 110
D05B 5702
D05B 6902

US Classification:

112199

Abstract:

A Cardan gear assembly having an output centerpoint means which moves along an elliptical path. A force transfer means connects the output centerpoint to a means operative to carry a work performing means. The major axis swept out by the means operative being skewed with respect to the major axis of the ellipse which is swept out by the output centerpoint. As a result, the work performing means will be swept along a curve which is of a portion of a helix as well as part elliptical. This curve takes the form of a partial helix wherein the outgoing path is different from the return path.

Inventors:

Thomas J. Bock - Streamwood IL

Assignee:

Borg-Warner Corporation - Chicago IL

International Classification:

F16H 1106

US Classification:

474 11

Abstract:

A variable pulley torque drive system comprising a pair of flexible straps, each connected at one end to a pivot on a drive member or a movable pulley sheave, and at the other end to the other of either the movable sheave or drive member, the straps being in tension when driving and flexed and deflected to compression in the undriven mode.
