Abstract
Abstract A cable cylinder particularly suited for use in a rock drill guiding and supporting structure comprises an elongated member having a cylindrical bore extending therethrough. A carriage on which a rock drill, for example, may be detachably mounted, is guidedly supported on the outside of the elongated member and connected by cables to a piston disposed within the bore, such cables extending around pulleys at each end of the elongated member. Hoses serve to supply air under pressure to the bore on a desired side of the piston to cause longitudinal movement of that piston within the bore and consequently longitudinal movement in the opposite direction of the carriage and of a rock drill supported thereon.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
138 words
In the drill steel actuating tool of a mobile rock drilling machine in combination, i. a cable cylinder of extruded material having formed therein a. at least one longitudinally extending guideway for accommodating a superposed drill tool supporting carriage in slideable connection with said guideway, and b. at least one longitudinally exTending keyway for facilitating the slideable or rigid support of said cable cylinder, ii. rotatable cable cylinder mounting means engageable with said keyway, and iii. drill rod centering means on said cable cylinder said mounting means being adapted releasably to secure said cable cylinder to a supporting member at any desired angular position with respect thereto and to permit releasable securement of said cable cylinder for longitudinal movement in any desired direction in the parallel planes on which lie both said supporting member and said cable cylinder.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
71 words
The invention according to claim 1 in which said centering means are moveably mounted on said cable cylinder adjacent one end thereof and comprise a pair of pivotally mounted drill steel-centering arms having opposed recesses adapted to encircle said drill steel when said arms are transversely pivoted toward each other, and to permit said drill steel to be removed transversely from between said arms when said arms are transversely pivoted apart.
Claim 4
Dependent Claim
50 words
The invention according to claim 1 in which said centering means includes a generally U-shaped drill steel holding member pivotally mounted about a transversely disposed axis and adapted to support a drill steel therein and to be pivoted downwardly about said transversely disposed axis to disengage such a drill steel.
Claim 5
Dependent Claim
45 words
The invention according to claim 1 in which said mounting means includes a fluid operated ram adapted to be connected between a supporting member and said cable cylinder and operative to adjust said longitudinal position of said cable cylinder with respect to said supporting member.
Claim 6
Dependent Claim
71 words
The invention according to claim 4 in which said mounting means has at least two parallel opposed and longitudinally extending guideways adapted slideably to receive corresponding guide flanges of said carriage, there being at least two of said keyways arranged in parallel relationship said keyways being adapted slidingly to receive corresponding guide members provided on said supporting member and to be engaged by releaseable clamping means of said fluid operated ram.
Claim 7
Dependent Claim
97 words
The invention according to claim 1 in which said cable cylinder includes two keyways extending for the length thereof, each of said keyways being located on one side and the other of the vertical axial plane of said cylinder, each of said keyways, in cross section at right angles to the longitudinal axis of said cable cylinder being seen to consist of a groove having an upper outwardly inclining wall and a downwardly and outwardly inclining wall to accomodate and facilitate the ready attachment and detachment from said keyways of complementary engaging means on said mounting means.
Claim 8
Dependent Claim
58 words
The invention according to claim 6 in which said guideway is in the form of an open ended recess in said cable cylinder taking the form, when viewed at right angles to the longitudinal axis of said cylinder of an inverted T, being adapted and so designed as to accomodate a complementary formation projecting downwardly from said carriage.
Claim 9
Dependent Claim
61 words
The invention according to claim 7 in which said cable cylinder includes, in addition to a central bore, additional longitudinally extending bores for the flow of fluid to and from said centering means for effecting operation of said centering means, said centering means being adapted to be fluid actuated for movement between a drill steel-engaging position and a drill steel-releasing position.
