Typebar assembly

Claim 2

Claim 3

The type element according to claim 1 wherein said type element is provided with a second groove in said another face and said second groove is transverse to said first groove.

Claim 4

The type element according to claim 1 wherein said first groove is formed with a step portion to provide an abutment therein.

Claim 5

The type element according to claim 2 wherein said second groove is deeper than said first groove.

Claim 6

A separable typebar assembly for business machines comprising in combination: a typebar having a yoke-shaped distal end, said distal end including an upper arm and a lower arm, a lower lug extending from said lower arm and an upper lug extending from said upper arm; a type element having a face with at least one character embossed thereon, means defining an aperture on an end for receiving one of said lugs, means defining a first groove and a second groove transverse to said first groove on another end for receiving the other of said lugs; and means for urging said type element into engagement with said distal end for locking said type element on said distal end.

Claim 7

A separable typebar assembly for business machines comprising in combination: a typebar having a yoke-shaped distal end, said distal end including an upper arm and a lower arm, a lower lug extending from said lower arm and an upper lug extending from said upper arm; a type element having a face with at least one character embossed thereon, means defining an aperture on an end for receiving one of said lugs, means defining a first groove and a second groove transverse to said first groove on another end for receiving the other of said lugs; and means for urging said type element into engagement with said distal end for locking said type element on said distal end.

Claim 8

A separable typebar assembly as defined in claim 5 wherein said upper lug and said lower lug extend toward one another for spanning said type element ends for supporting said type element.

Claim 9

A separable typebar assembly as defined in claim 5 wherein said upper lug is in alignment with said lower lug and said type element aperture is in alignment with said type element recess for supporting said type element in a direction transverse to said embossed face.

Claim 10

A separable typebar assembly as defined in claim 5 wherein said urging means is a spring.

Claim 11

A separable typebar assembly as defined in claim 8 wherein said lower lug extends into said aperture for abutting and compressing said spring for urging said type element into engagement with and maintaining engagement of said type element and said distal end.

Claim 12

A removable typebar assembly for business macnines comprising in combination: a type element for carrying a type character on one face thereof and provided with a first groove and a second groove in one end thereof and an aperture in an opposite end thereof extending partially therethrough; a typebar having a distal end formed for engaging said first groove for aligning and holding said type element relative to said distal end; a spring confined entirely within said type element aperture between said distal end and said type element for maintaining pOsitive engagement of said type element groove with said distal end; a lower lug on said distal end of said typebar extending partially into said aperture of said type element for abutting and compressing said spring for urging said type element into engagement with and maintaining engagement of said type element relative to said distal end; and an upper lug on said distal end receivable by said second groove to disengage said first mentioned groove from said distal end to permit rotation of said print element.

Claim 13

A removable typebar assembly for business macnines comprising in combination: a type element for carrying a type character on one face thereof and provided with a first groove and a second groove in one end thereof and an aperture in an opposite end thereof extending partially therethrough; a typebar having a distal end formed for engaging said first groove for aligning and holding said type element relative to said distal end; a spring confined entirely within said type element aperture between said distal end and said type element for maintaining pOsitive engagement of said type element groove with said distal end; a lower lug on said distal end of said typebar extending partially into said aperture of said type element for abutting and compressing said spring for urging said type element into engagement with and maintaining engagement of said type element relative to said distal end; and an upper lug on said distal end receivable by said second groove to disengage said first mentioned groove from said distal end to permit rotation of said print element.

Claim 14

A removable typebar assembly for business machines comprising in combination: a type element for carrying a type character on one face thereof and provided with a first groove and a second groove in an upper end thereof and an aperture in a lower end thereof extending partially therethrough; a typebar having a distal end that includes a yoke formed for engaging said first groove for aligning and holding said type element relative to said distal end; a spring confined entirely within said type element aperture between said distal end and said type element for maintaining positive engagement of said type element groove with said distal ends; a lower lug extending from one end of said yoke extending partially into said aperture of said type element for abutting and compressing said spring for urging said type element into pivotal engagement with and maintaining engagement of said type element relative to said distal end; and an upper lug on said yoke projecting a fixed distance toward and in alignment with said lower lug for engaging said upper end of said type element for substantially spanning the type element for securely supporting the type element relative to said typebar.

Claim 15

A removable typebar assembly for business machines comprising in combination: a type element for carrying a type character on one face thereof and provided with a first groove and a second groove in an upper end thereof and an aperture in a lower end thereof extending partially therethrough; a typebar having a distal end that includes a yoke formed for engaging said first groove for aligning and holding said type element relative to said distal end; a spring confined entirely within said type element aperture between said distal end and said type element for maintaining positive engagement of said type element groove with said distal ends; a lower lug extending from one end of said yoke extending partially into said aperture of said type element for abutting and compressing said spring for urging said type element into pivotal engagement with and maintaining engagement of said type element relative to said distal end; and an upper lug on said yoke projecting a fixed distance toward and in alignment with said lower lug for engaging said upper end of said type element for substantially spanning the type element for securely supporting the type element relative to said typebar.
