Abstract
Abstract A foot-operable electromechanical paper feeding device designed to display handwritten or printed information in continual serial line order for transcription to typewritten copy or computer terminal entry. The transcription copy feeder displays single lines of any letter height in a fixed horizontal space directly behind the typewriter or keyboard, and may be operated to feed paper in forward or reverse at variable speed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
241 words
A transcription-copy feeder comprising two vertical support members attached to a horizontal L-shaped bracket, a powered feed roller rotatably mounted between said vertical support members, a reversibly rotatable electric motor for continuously driving said feed roller, a remote portable contact switch for activating said electric motor, a capacitor mediated remote two-position switch for electrically reversing the rotation of said electric motor, a free-rolling tension roller rotatably mounted on a support frame, said support frame pivotally attached to said vertical members, said support frame spring-loaded to said vertical support members to establish manually-releasable pressure contact to said feed roller, said feed roller provided with rubber friction rings to present a non-slip surface, said feed roller being operable when driven by said electric motor to translate transcription-copy paper between the contact junction made with said tension roller, a stationary index bar mounted between said vertical support members, said index bar located above said tension roller and forward of feed line of said transcription-copy paper at said contact junction to provide a stationary line index, a vertical keeper bar mounted between said vertical support members, said vertical keeper bar located above said index marker and behind said transcription-copy paper feedline to maintain said transcription-copy paper in a vertical position, a deflector bar mounted between said vertical support members, said deflector bar located above said feed roller and behind said vertical keeper bar to deflect said transcription-copy paper toward the rear of said transcription-copy feeder.

Claim 3
Dependent Claim
26 words
A transcription-copy feeder as defined in claim 1 in which said remote portable contact switch for activating said electric motor comprises a foot-operable electrical contact switch.
Claim 4
Dependent Claim
41 words
A transcription-copy feeder as defined in claim 1 in which the said remote portable contact switch for activating said electric motor and the said capacitor mediated remote switch for reversing said electric motor are incorporated in a dual function foot-operable switch.
Claim 5
Dependent Claim
30 words
A transcription-copy feeder as defined in claim 1 in which the speed of the said electric motor is electrically variable over the range of 10 to 60 revolutions per minute.
