Abstract

Abstract A workpiece such as a paper or a card is held in proper position in a typewriter having a paper scale for typing to the bottom of the workpiece without side slippage by the inventive workpiece holders. Each of the pair of holders mounts fixably, detachably, and slidably flush with the outer surface of the paper scale and has an inner member positioned when mounted such as to be parallel to the outer surface of the paper scale and at a suitable distance out and on each side of the workpiece for free movement of the workpiece between the member and the outer surface of the paper scale.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 389 words
Workpiece holders for holding a workpiece in proper position in a typewriter having a paper scale, the paper scale having a flat outer surface and a flat upper surface which is generally perpendicular to the flat outer surface, the flat outer surface and the flat upper surface having a cross section corresponding to the outer surfaces of an inverted L, the workpiece being held in proper position for typing to the bottom line of the workpiece without side slippage near the bottom of the workpiece, the workpiece holders comprising: a left workpiece holder and a right workpiece holder, each workpiece holder having; a body adapted for fixable, detachable, and slidable mounting flush with the outer surface of the paper scale of the typewriter, the body of the workpiece holder having an inner surface corresponding to the general cross sectional shape of an inverted J adapted for fitting over the flat outer surface and the flat upper surface of the paper scale, the inner surface of the body being comprised of a magnetic material for easily fixable, slidable, and detachable mounting on the outer surface of the paper scale, and each workpiece holder also having an inner member, upon mounting, positioned parallel to the outer surface of the paper and at a distance out from the outer surface of the paper scale sufficient that free movement of the workpiece between the member and the outer surface of the paper scale is possible, characterized further in that: the outer portion of the body member is molded of a plastic, the inner member of each workpiece is comprised of a transparent meaterial, the inner member is adhered to an inner elongated portion of the inverted J cross section over the horizontal length of the body and extending integrally to form the inner member, and cross sectionally inner of the J cross-section a magnetic material is adhered for mounting the workpiece holder fixably, detachably, and slidably flush with the outer surface of the paper scale of the typewriter, the magnetic material being of sufficient thickness to maintain the inner member in a position parallel to the outer surface of the scale and at a suitable distance out from the outer surface of the paper scale for free movement of the workpiece between the inner member and the outer surface of the paper scale.
Claim 2
Dependent Claim 389 words
Workpiece holders for holding a workpiece in proper position in a typewriter having a paper scale, the paper scale having a flat outer surface and a flat upper surface which is generally perpendicular to the flat outer surface, the flat outer surface and the flat upper surface having a cross section corresponding to the outer surfaces of an inverted L, the workpiece being held in proper position for typing to the bottom line of the workpiece without side slippage near the bottom of the workpiece, the workpiece holders comprising: a left workpiece holder and a right workpiece holder, each workpiece holder having; a body adapted for fixable, detachable, and slidable mounting flush with the outer surface of the paper scale of the typewriter, the body of the workpiece holder having an inner surface corresponding to the general cross sectional shape of an inverted J adapted for fitting over the flat outer surface and the flat upper surface of the paper scale, the inner surface of the body being comprised of a magnetic material for easily fixable, slidable, and detachable mounting on the outer surface of the paper scale, and each workpiece holder also having an inner member, upon mounting, positioned parallel to the outer surface of the paper and at a distance out from the outer surface of the paper scale sufficient that free movement of the workpiece between the member and the outer surface of the paper scale is possible, characterized further in that: the outer portion of the body member is molded of a plastic, the inner member of each workpiece is comprised of a transparent meaterial, the inner member is adhered to an inner elongated portion of the inverted J cross section over the horizontal length of the body and extending integrally to form the inner member, and cross sectionally inner of the J cross-section a magnetic material is adhered for mounting the workpiece holder fixably, detachably, and slidably flush with the outer surface of the paper scale of the typewriter, the magnetic material being of sufficient thickness to maintain the inner member in a position parallel to the outer surface of the scale and at a suitable distance out from the outer surface of the paper scale for free movement of the workpiece between the inner member and the outer surface of the paper scale.
Claim 3
Dependent Claim 41 words
The workpiece holders of claim 1 characterized such that the inner member is positioned at a suitable distance out from the outer surface of the paper scale for free movement of a common sheet of paper or card as the workpiece.
