Abstract
Abstract An automatic system for operating the push buttons of a telephone keyboard includes a dialer frame with side members and a plurality of partitions forming spaced slots. The frame is adapted to overlay the push buttons and the slots formed by the partitions. The side members extend normal to the plane of the push button array and parallel to the length of the rows. Actuators are pivotally mounted in the slots, one in each slot, with each actuator having a bottom foot to contact one of the push buttons. Each actuator also has an upwardly facing hook. A perforated card moved along the top of the frame in the direction of the length of the slots engages at its perforations the actuator hooks. The hooks move to rotate the actuators for depression of the underlying push button, while releasing the hook from the perforations. The dialer frame is also provided with an array of manual keys substantially duplicating the array of the push button telephone to which the device is to be applied. Thus, there is provided a device for selectively actuating keys arrayed in columns and rows by manual use of a perforated card with the device in place.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
140 words
A device for selectively actuating keys in an array of columns and rows by use of a perforated card comprising: (a) a frame adapted to overlay said keys, (b) partition means in said frame defining slots in number equal to the number of said keys which slots extend normal to the plane of said array and parallel to the length of said rows, and (c) actuators each having an upfacing upwardly urged hook mounted to operate such that there is one in each of said slots, each actuator being pivotally mounted and having a bottom foot to contact one of said keys, whereby a perforated card moved along the top of said frame in the direction of the length of said slots with perforations therein selectively engages and moves said hooks to rotate said actuators for depression of said keys.
Claim 2
Independent Claim
140 words
A device for selectively actuating keys in an array of columns and rows by use of a perforated card comprising: (a) a frame adapted to overlay said keys, (b) partition means in said frame defining slots in number equal to the number of said keys which slots extend normal to the plane of said array and parallel to the length of said rows, and (c) actuators each having an upfacing upwardly urged hook mounted to operate such that there is one in each of said slots, each actuator being pivotally mounted and having a bottom foot to contact one of said keys, whereby a perforated card moved along the top of said frame in the direction of the length of said slots with perforations therein selectively engages and moves said hooks to rotate said actuators for depression of said keys.
Claim 3
Dependent Claim
33 words
The combination of claim 1 in which means are provided to move said hook away from the top of said frame to disengage said hooks from said perforations as said keys are depressed.
Claim 4
Dependent Claim
28 words
The combination set forth in claim 2 in which a camming plate at the top of said frame forces said hooks downward as they move with said card.
Claim 5
Independent Claim
168 words
A device for mechanically operating selected keys arrayed in columns and rows along a surface comprising: (a) a frame adapted to overlay said keys with the bottom of said frame at about the plane of the top of said keys, (b) structure in said frame defining slots normal to the plane of said array and extending the length of each row in number equal to the number of said keys, (c) an actuator pivotally mounted adjacent to each one of said keys and each actuator having an engageable member at the upper surface of said frame which is normally positioned along a transverse base line, one actuator in each of said slots, each said actuator having a bottom foot in contact with one of said keys, and (d) a card structured to cooperate with said engageable member to move said engageable member away from said base line in the direction of the length of said rows to rotate said actuator to depress the adjacent key by said foot.
Claim 6
Independent Claim
168 words
A device for mechanically operating selected keys arrayed in columns and rows along a surface comprising: (a) a frame adapted to overlay said keys with the bottom of said frame at about the plane of the top of said keys, (b) structure in said frame defining slots normal to the plane of said array and extending the length of each row in number equal to the number of said keys, (c) an actuator pivotally mounted adjacent to each one of said keys and each actuator having an engageable member at the upper surface of said frame which is normally positioned along a transverse base line, one actuator in each of said slots, each said actuator having a bottom foot in contact with one of said keys, and (d) a card structured to cooperate with said engageable member to move said engageable member away from said base line in the direction of the length of said rows to rotate said actuator to depress the adjacent key by said foot.
Claim 7
Dependent Claim
62 words
The combination set forth in Claim 4 in which each said actuator has a pawl plate with an extending foot and an integral beam spring which extends parallel to the plane of said keys and is urged away from said plane with an upstanding hook directed away from said plane and shaft means extending through said frame pivotally mounting said pawl plate.
Claim 8
Dependent Claim
34 words
The combination set forth in claim 5 in which a transverse cam plate at the top of said partitions spaced from the forward end forces said hook member downward under movement by said card.
Claim 9
Dependent Claim
42 words
The combination set forth in claim 5 in which a link extends from a point on said beam spring adjacent said engageable member to a point therebelow together said engageable member and force it downward as it is moved by said card.
Claim 10
Dependent Claim
136 words
In a device for mechanically operating selected keys arrayed in columns and rows along a surface where a frame overlays said keys with structure in said frame extending to a card way above said keys to define slots normal to the plane of said array in number equal to the number of keys in said array, the combination comprising: (a) actuators each including a hook directed away from said keys and urged upward into said way in each said slot and a pawl plate connected to each of said hooks, pivotally mounted with a bottom actuator foot in contact with one of said keys, and (b) a card perforated to engage said hooks selectively to rotate said actuators to depress the keys contacted by the respective actuator feet while moving said hooks lengthwise of said slots.
Claim 11
Dependent Claim
136 words
In a device for mechanically operating selected keys arrayed in columns and rows along a surface where a frame overlays said keys with structure in said frame extending to a card way above said keys to define slots normal to the plane of said array in number equal to the number of keys in said array, the combination comprising: (a) actuators each including a hook directed away from said keys and urged upward into said way in each said slot and a pawl plate connected to each of said hooks, pivotally mounted with a bottom actuator foot in contact with one of said keys, and (b) a card perforated to engage said hooks selectively to rotate said actuators to depress the keys contacted by the respective actuator feet while moving said hooks lengthwise of said slots.
Claim 12
Dependent Claim
37 words
The combination set forth in claim 8 in which each said actuator includes said bottom foot and a second member spaced therefrom to move said foot downward in said frame as said hook moves along its slot.
Claim 13
Dependent Claim
33 words
The combination set forth in claim 8 in which said actuator includes a resilient cantilevered beam rooted at one end in said pawl plate and carries said hook at the other end thereof.
