Abstract
Abstract An endless tape for an impact printer is provided with separate groups of flexible fingers which project laterally from and along one side edge of the tape. The fingers of each groups are formed integrally with a common base and the base is removably attached in face-to-face relation to the tape. The ''''grain'''' of the material of the tape extends longitudinally of the tape in order most effectively to resist tape breakage due to the flexing of the tape as it is travelled along its endless path, whereas the grain of the material of the groups of fingers extends longitudinally of the fingers likewise to maximize their lives incidental to the flexing of these fingers caused by the striking hammers.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
184 words
A type-carrying assembly for impact printers, comprising in combination: an endless, flexible tape adapted to be supported by the typecarrying drive of an impact printer; and a series of type-bearing members secured to said tape along the length thereof, each such member comprising an elongate strip of stiff, resilient material presenting a base portioN disposed in face-to-face relation with said tape to extend transversely thereof and a free end portion projecting laterally of the tape, said free end portion providing a series of flexible and resilient type-bearing fingers joining said base portion near that edge of the tape from which said free end portion projects and extending therefrom essentially perpendicular to the length of the tape, said fingers being separated from each other, said tape being provided with transversely spaced openings for each member, and the base portion of each member being provided with locking tab means consisting of a pair of oppositely directed and outwardly offset tangs adapted to fit through said openings when the member is sprung into bowed shape and to lock with the tape when released from such bowed shape.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
54 words
A type-bearing assembly as defined in claim 1 wherein said openings are each of generally U-shape and each is disposed adjacent a corresponding edge of the tape with the bights of the U-shapes located innermost from such edges whereby to present mutually opposed tongues, the tangs of each said member engaging over said tongues.
Claim 4
Dependent Claim
34 words
A type-bearing assembly as defined in claim 2 wherein each member also includes a pair of outwardly projecting ears adjacent each tang and snugly engaging opposite sides of a corresponding tongue of said tape.
Claim 5
Dependent Claim
32 words
A type-bearing assembly as defined in claim 3 wherein each tongue is of T-shape with said ears of each pair thereof engaging opposite sides of the stem of a corresponding T-shaped tongue.
Claim 6
Dependent Claim

A type-bearing assembly as defined in claim 1 wherein one opening of each pair is round and the other opening is rectangular.
Claim 8
Dependent Claim
58 words
A type-bearing assembly as defined in claim 1 wherein each member is provided with an opening at the region of each tang, the base portion of each member being provided on one side thereof with a layer of synthetic resinous material, said tangs projecting through said openings in the base portion and being integrally formed with said layer.
Claim 9
Dependent Claim
58 words
A type-bearing assembly as defined in claim 5 wherein each member is provided with an opening at the region of each tang, the base portion of each member being provided on one side thereof with a layer of synthetic resinous material, said tangs projecting through said openings in the base portion and being integrally formed with said layer.
Claim 10
Dependent Claim
58 words
A type-bearing assembly as defined in claim 6 wherein each member is provided with an opening at the region of each tang, the base portion of each member being provided on one side thereof with a layer of synthetic resinous material, said tangs projecting through said openings in the base portion and being integrally formed with said layer.
