Abstract
Abstract The disclosure describes an apparatus for laying tiles or the like on a surface. The apparatus holds the tile over a surface portion which is covered with an adhesive material and on which the tile is intended to be laid, and allows it to contact the adhesive. A vibration is produced so that when the tile is in contact with the surface portion covered with the adhesive material, it becomes embedded therein thereby being fixed on the surface portion. Thereafter, the tile is released. The apparatus advantageously replaces the common practice of laying tiles by hand.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
223 words
Apparatus for laying tiles on a surface in a predetermined arrangement, wherein each tile is laid individually at a given distance from neighboring, already laid tiles, which comprises an enclosure; holding means mounted on said enclosure for holding a tile over a surface portion covered with an adhesive material, said surface portion being intended to receive said tile, said holding means further permitting said tile to contact said adhesive material; a pair of extendable arms laterally extending from said enclosure on front and back sides thereof; an adjustable leg at the end of each of said arms, wherein one of said adjustable legs is placed on a tile which has been laid while the other of said legs is directly placed on said surface portion; joint spacers dependent from each of said arms and parallel with said legs for correctly spacing a tile relative to adjoining tiles so as to form a joint of predetermined width between adjoining tiles; vibration means associated with said enclosures and operative when said tile is in contact with said surface portion covered with said adhesive material, said vibration means causing said tile to become embedded in said adhesive material and become fixed on said surface portion; and releasing means enabling said holding means to release said tile after said tile has been fixed on said surface portion.
Claim 2
Dependent Claim
223 words
Apparatus for laying tiles on a surface in a predetermined arrangement, wherein each tile is laid individually at a given distance from neighboring, already laid tiles, which comprises an enclosure; holding means mounted on said enclosure for holding a tile over a surface portion covered with an adhesive material, said surface portion being intended to receive said tile, said holding means further permitting said tile to contact said adhesive material; a pair of extendable arms laterally extending from said enclosure on front and back sides thereof; an adjustable leg at the end of each of said arms, wherein one of said adjustable legs is placed on a tile which has been laid while the other of said legs is directly placed on said surface portion; joint spacers dependent from each of said arms and parallel with said legs for correctly spacing a tile relative to adjoining tiles so as to form a joint of predetermined width between adjoining tiles; vibration means associated with said enclosures and operative when said tile is in contact with said surface portion covered with said adhesive material, said vibration means causing said tile to become embedded in said adhesive material and become fixed on said surface portion; and releasing means enabling said holding means to release said tile after said tile has been fixed on said surface portion.
Claim 3
Dependent Claim
19 words
Apparatus according to claim 1, further comprising levelling means for adjusting said enclosure to a horizontal or vertical level.
Claim 4
Dependent Claim
57 words
Apparatus according to claim 1, wherein said holding means comprises a suction cup mounted on said enclosure and means to operatively connect said cup to an air compressor, said suction cup being utilized for holding said tile when operatively connected to said air compressor and for releasing said tile when contact with said air compressor is closed.
Claim 5
Dependent Claim
47 words
Apparatus according to claim 3, wherein said vibration means comprises a vibrator mounted in said closure to induce a vibration in said enclosure, said vibration being thereby communicated to said suction cup and consequently to said tile when the latter is being laid on said surface portion.
Claim 6
Dependent Claim
163 words
Apparatus according to claim 4, wherein said enclosure further comprises a vacuum generator, said vacuum generator being operatively connected to said suction cup for operation of said handle for connection to said air compressor by means of an air hose, an air duct provided in said handle, said handle . also including a manifold, said manifold being connected to said air duct, said manifold having a first outlet and a second outlet, a first air connection between said first air outlet and said vacuum generator, and a second air connection between said second air outlet and said vibrator, a vacuum valve at said first air outlet and a vibrator valve at said second air outlet, so that by opening said vacuum valve, said vacuum generator becomes operative to enable said suction cup to hold a tile, and by opening said vibrator valve, said vibrator induces a vibration in said enclosure to cause said tile to vibrate when being laid onto the surface portion.
Claim 7
Dependent Claim
22 words
Apparatus according to claim 5, which further comprises first bubble levels on said arms to adjust the horizontal level of said tile.
Claim 8
Dependent Claim
65 words
Apparatus according to claim 6, which comprises a rectangular side arm perpendicular to both said extendable arms, an adjustable leg provided on the outer side of said rectangular side arm, wherein joint spacers are dependent from both lateral sides of said rectangular side arm, and second bubble levels on said rectangular side arm to adjust the vertical level of a tile mounted on a wall.
Claim 9
Dependent Claim
32 words
Apparatus according to claim 7, which comprises a secondary rectangular handle laterally projecting from said enclosure opposite said rectangular side arm to further help in placing a tile in a perfect location.
