Abstract
Abstract An attachment adapted to be used with a push-button telephone having an array of telephone push buttons for facilitating the actuation of them, includes a series of finger discs corresponding to at least some of the telephone push buttons and bearing indicia on their upper faces, and a series of links fixedly connected to the lower faces of the discs extending to the telephone push buttons through apertures in a cup-shaped housing adapted to fit over the array of telephone push buttons which can be actuated by depressing the finger dics. At least some of the links are in the form of legs having an intermediate offset portion so that the upper faces of the discs may be larger in size and spaced further apart than the corresponding telephone push buttons to facilitate ready location of and manipulation of the finger discs.

Claim 1
Independent Claim
223 words
An attachment adapted to be used with a push button telephone having an array of telephone push buttons, said attachment comprising: a cup-shaped housing having an opened mouth adapted to fit over the array of push buttons of the telephone and to be secured in place thereover, said housing having a plate, said plate including an array of apertures extending therethrough, said plate having inner and outer faces; an array of finger discs corresponding to at least some of the telephone push buttons for actuating them and bearing indicia on the front faces of said discs, said discs normally at least partially extending outwardly from the outer face of said plate, said discs having rear faces on the opposite side of said front faces; and a series of elongated legs fixedly connected to said rear faces and slidably extending through said apertures to the telephone push buttons for actuating them selectively when depressed and alternatively maintaining said discs normally at least partially extending outwardly from the outer face of said plate, at least one of said legs having an axially-extending front portion disposed in axial alignment with its aperture in said plate and having a laterally extending intermediate portion connected at its forward end to said front portion and terminating in a foot portion adapted to engage one of the telephone push buttons.
Claim 2
Dependent Claim
223 words
An attachment adapted to be used with a push button telephone having an array of telephone push buttons, said attachment comprising: a cup-shaped housing having an opened mouth adapted to fit over the array of push buttons of the telephone and to be secured in place thereover, said housing having a plate, said plate including an array of apertures extending therethrough, said plate having inner and outer faces; an array of finger discs corresponding to at least some of the telephone push buttons for actuating them and bearing indicia on the front faces of said discs, said discs normally at least partially extending outwardly from the outer face of said plate, said discs having rear faces on the opposite side of said front faces; and a series of elongated legs fixedly connected to said rear faces and slidably extending through said apertures to the telephone push buttons for actuating them selectively when depressed and alternatively maintaining said discs normally at least partially extending outwardly from the outer face of said plate, at least one of said legs having an axially-extending front portion disposed in axial alignment with its aperture in said plate and having a laterally extending intermediate portion connected at its forward end to said front portion and terminating in a foot portion adapted to engage one of the telephone push buttons.
Claim 3
Dependent Claim
50 words
An attachment according to claim 1, wherein each one of said apertures includes an enlarged portion for receiving its finger disc and a reduced diameter portion for reciprocatively receiving the forward portion of its leg, the intermediate and foot portions of said legs being disposed in back of said plate.
Claim 4
Dependent Claim
52 words
An attachment according to claim 2, wherein the cross-sectional shape of said enlarged portions of said apertures are complementary shaped relative to the cross-sectional shapes of said discs, the complementary cross-sectional shapes of said enlarged portions and said discs causing said discs and said legs fixed thereto to resist axial rotation thereof.
Claim 5
Dependent Claim
47 words
An attachment according to claim 3, wherein the rear face of said plate includes means defining a plurality of orientation grooves for each one of said legs having intermediate offset portions to receive them when said discs are withdrawn partially from their enlarged portions of their apertures.
Claim 6
Dependent Claim
50 words
An attachment according to claim 3, wherein one of said legs includes longer intermediate portions and shorter laterally offset intermediate portions, further including at least one leg having an axially-extending front portion aligned with its aperture and terminating in its foot portion disposed in axial alignment with its front portion.
Claim 7
Dependent Claim
24 words
An attachment according to claim 5, further including a plurality of stiffening webs connected integrally to said legs having said offset intermediate portions thereat.
Claim 8
Dependent Claim
17 words

Claim 9
Dependent Claim
47 words
An attachment according to claim 1, wherein the rear face of said plate includes means defining a plurality of orientation grooves for each one of said legs having intermediate offset portions to receive them when said discs are withdrawn partially from their enlarged portions of their apertures.
Claim 10
Dependent Claim
50 words
An attachment according to claim 1, wherein one of said legs includes longer intermediate portions and shorter laterally offset intermediate portions, further including at least one leg having an axially-extending front portion aligned with its aperture and terminating in its foot portion disposed in axial alignment with its front portion.
Claim 11
Dependent Claim
47 words
An attachment according to claim 9, wherein the rear face of said plate includes means defining a plurality of orientation grooves for each one of said legs having intermediate offset portions to receive them when said discs are withdrawn partially from their enlarged portions of their apertures.
