Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
181 words
A machine for building walls and having an aligning head structure for accurately positioning a plurality of building elements which have previously been laid in rough alignment on a layer of mortar, the aligning head structure comprising a supporting means, an elongated aligning member, means resiliently attaching said elongated aligning member to said supporting means, means mounting said head structrure for movement to place said elongated aligning member into contact with the top surfaces of the plurality of building elements, a plurality of fingers moveably connected to said supporting means, the fingers being arranged in two rows which extend parallel to one another and which rows are spaced apart, and the fingers further being arranged to depend downwardly on each side of the building elements when the head is in a position above them, there being means for displacing the two rows of fingers towards one another to grip the building elements and bring each side surface of each building element into alignment with the corresponding side surfaces of the other building elements and means for vibrating said elongated aligning member.
Claim 2
Dependent Claim
181 words
A machine for building walls and having an aligning head structure for accurately positioning a plurality of building elements which have previously been laid in rough alignment on a layer of mortar, the aligning head structure comprising a supporting means, an elongated aligning member, means resiliently attaching said elongated aligning member to said supporting means, means mounting said head structrure for movement to place said elongated aligning member into contact with the top surfaces of the plurality of building elements, a plurality of fingers moveably connected to said supporting means, the fingers being arranged in two rows which extend parallel to one another and which rows are spaced apart, and the fingers further being arranged to depend downwardly on each side of the building elements when the head is in a position above them, there being means for displacing the two rows of fingers towards one another to grip the building elements and bring each side surface of each building element into alignment with the corresponding side surfaces of the other building elements and means for vibrating said elongated aligning member.
Claim 3
Dependent Claim
58 words
A machine according to claim 1, wherein the fingers are arranged in sets, there being a set of fingers for each building element, at least one finger of each set being longer than at least one other finger whereby a turning moment is exerted upon a gripped building element to hold it in contact with said aligning member.
Claim 4
Dependent Claim
20 words
A machine according to claim 1, and including fluid-operated actuators for displacing the fingers into gripping engagement with building elements.
Claim 5
Dependent Claim
37 words
A machine according to claim 1, wherein said aligning head structure is mounted for swinging movement about a horizontal axis, and said mounting means includes fluid-operated means are for swinging said aligning head structure about said axis.
Claim 6
Dependent Claim
43 words
A machine according to claim 1, and further comprising horizontal guide means which are elongated in the direction parallel to the line along which it is intended to build a wall, and means for displacing the aligning head structure along said guide means.
Claim 7
Dependent Claim
39 words
A machine according to claim 1, and said mounting means further comprising means for displacing said aligning head structure horizontally in a fore and aft direction at right angles to the line along which the machine builds a wall.
Claim 8
Dependent Claim
25 words
A machine according to claim 1, and further comprising a rig having columns and means for displacing the aligning head up and down said columns.
Claim 9
Dependent Claim
87 words
A machine according to claim 7, and further inclUding rollers for running on a pipe which extends horizontally and parallel to the direction in which the machine is capable of building a wall, and a further wheel which is arranged in tricycle fashion with respect to the rollers, the said wheel being mounted on an arm which is pivotally connected to the rig, there being means for sensing the position of the rig and swinging said arm about said pivotal connection if said columns are not vertical.
Claim 10
Dependent Claim
42 words
A machine according to claim 8, wherein the sensing means includes a pendulum, electrical sensing means actuated by the pendulum, and an electric motor which is energised to displace said arm about said pivotal mounting when said pendulum actuates said sensing means.
Claim 11
Dependent Claim
29 words
A machine according to claim 1, wherein interlocking means are provided for preventing displacement of the fingers unless said aligning head is properly positioned for aligning said building elements.
Claim 12
Dependent Claim
30 words
A machine according to claim 1, wherein interlocking means are provided for preventing movement of said head structure after said finger commence their movement towards one another for gripping purposes.
