Abstract

Abstract A mounting device for a flying head or a flying block having a number of flying heads used with magnetic drum storage apparatus comprising stationary location means providing location points for the head or block in an operative position close to a drum. One of the location points has a fixed pivot adapted to allow the head or block universal pivotal freedom about the pivot. Another of the location points has a stop member positioned to engage an abutment on the head or block to limit its pivotal movement about a yaw axis.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 76 words
A mounting device for a flying head or block comprising a stationary structure to which is rigidly fixed a universal pivot on which the head or block is mounted with universal freedom and a stop member on said stationary structure positioned to locate said head or block about the yaw axis of the head or block, said pivot and said stop member providing the only location points for the head or block in its operative position.
Claim 2
Dependent Claim 76 words
A mounting device for a flying head or block comprising a stationary structure to which is rigidly fixed a universal pivot on which the head or block is mounted with universal freedom and a stop member on said stationary structure positioned to locate said head or block about the yaw axis of the head or block, said pivot and said stop member providing the only location points for the head or block in its operative position.
Claim 3
Dependent Claim 36 words
A mounting device as claimed in claim 1, wherein said universal pivot is a needle rigidly fixed in said stationary structure and having its pointed end seated in a conical opening in the head or block.
Claim 4
Dependent Claim 93 words
A mounting device for a flying head or block comprising a stationary structure to which is rigidly fixed a universal pIvot on which the head or block is mounted with universal freedom at a position in advance of the leading edge of the head or block and a stop member on said stationary structure positioned in rear of the trailing edge of the head or block to locate it about the yaw axis, said pivot and said stop member providing the only location points for the head or block in its operative position.
Claim 5
Dependent Claim 93 words
A mounting device for a flying head or block comprising a stationary structure to which is rigidly fixed a universal pIvot on which the head or block is mounted with universal freedom at a position in advance of the leading edge of the head or block and a stop member on said stationary structure positioned in rear of the trailing edge of the head or block to locate it about the yaw axis, said pivot and said stop member providing the only location points for the head or block in its operative position.
Claim 6
Dependent Claim 29 words
A mounting device as claimed in claim 3, wherein said stop member is adjustable on said stationary structure in the direction of yaw movements of the head or block.
Claim 7
Dependent Claim 154 words
A mounting device for a flying head or block comprising stationary structure providing a universal pivot on which the head or block is mounted at a position in advance of the leading edge of the head or block and a stop member on said stationary structure positioned in rear of the trailing edge of the head or block to locate it about the yaw axis, said pivot and said stop member providing the only location points for the head or block in its operative position, wherein said stop member is adjustable on said stationary structure in the direction of yaw movements of the head or block, and comprises a cylindrical surface and a tension spring between the cylindrical surface and the head or block, said stop member having an opening off center with respect to the cylindrical surface and means passing through said offcenter opening to secure the stop member to said stationary structure.
Claim 8
Dependent Claim 154 words
A mounting device for a flying head or block comprising stationary structure providing a universal pivot on which the head or block is mounted at a position in advance of the leading edge of the head or block and a stop member on said stationary structure positioned in rear of the trailing edge of the head or block to locate it about the yaw axis, said pivot and said stop member providing the only location points for the head or block in its operative position, wherein said stop member is adjustable on said stationary structure in the direction of yaw movements of the head or block, and comprises a cylindrical surface and a tension spring between the cylindrical surface and the head or block, said stop member having an opening off center with respect to the cylindrical surface and means passing through said offcenter opening to secure the stop member to said stationary structure.
Claim 9
Dependent Claim 122 words
A mounting device for a flying head or block comprising a stationary structure to which is rigidly fixed a universal pivot on which the head or block is mounted with universal freedom and a stop member on said stationary structure positioned to locate said head or block about the yaw axis of the head or block, said pivot and said stop member providing the only location points for the head or block in its operative position comprising also retracting means, means for moving said retracting means between operative and inoperative positions, and abutments on said retracting means located in the operative position spaced from the head or block but which in the movement to the inoperative position engage the head or block.
Claim 10
Dependent Claim 122 words
A mounting device for a flying head or block comprising a stationary structure to which is rigidly fixed a universal pivot on which the head or block is mounted with universal freedom and a stop member on said stationary structure positioned to locate said head or block about the yaw axis of the head or block, said pivot and said stop member providing the only location points for the head or block in its operative position comprising also retracting means, means for moving said retracting means between operative and inoperative positions, and abutments on said retracting means located in the operative position spaced from the head or block but which in the movement to the inoperative position engage the head or block.
Claim 11
Dependent Claim 29 words
A mounting device as claimed in claim 6 wherein said retracting means comprises a spring frame substantially surrounding said head or block and pivotally mounted to said stationary structure.
Claim 12
Dependent Claim 24 words
A mounting device as claimed in claim 7, comprising also a spring engaging the head or block to urge it into the operative position.
Claim 13
Dependent Claim 127 words
A mounting device for a flying head or block, comprising stationary structure providing a universal pivot on which a head or block may be mounted, a stop member mounted on said stationary structure positioned to engage the head or block in the yaw direction of the head or block, a spring frame substantially surrounding the head or block and secured at one edge to the stationary structure, means for bending the spring frame about said one edge between operative and inoperative positions, and abutments on said spring frame located spaced from the head or block in the operative position but engaging the head or block in movement to the inoperative position so as to pivot the head or block about said universal pivot to an inoperative position.
Claim 14
Dependent Claim 127 words
A mounting device for a flying head or block, comprising stationary structure providing a universal pivot on which a head or block may be mounted, a stop member mounted on said stationary structure positioned to engage the head or block in the yaw direction of the head or block, a spring frame substantially surrounding the head or block and secured at one edge to the stationary structure, means for bending the spring frame about said one edge between operative and inoperative positions, and abutments on said spring frame located spaced from the head or block in the operative position but engaging the head or block in movement to the inoperative position so as to pivot the head or block about said universal pivot to an inoperative position.
Claim 15
Dependent Claim 27 words
A mounting device as claimed in claim 9, including means for adjusting the location of the spring frame along said secured edge relative to the stationary structure.
