The invention relates to a tiling machine comprising a frame with drive wheels and with a working cylinder pivotable relative to the frame, the piston rod is slidably engaged with a collar arm which carries a tile tong at its free end and which is rotatable at its opposite end. a suspension axis, which tiling machine has necessary energy accumulation means and auxiliary and operating means, which allow the lowering movement of the tongs in the loaded state and raising in the unloaded state.

Austrian Patent Specification No. 376,729 discloses a related machine in which the lowering movement of the tongs is connected by rotation about an axis of rotation fixed in connection with the frame of the machine. The lowering movement of the tongs can therefore not take place in an approximately vertical path.

German Pat. No. 2,241,503 discloses another related machine in which the suspension axis of the collar arm is arranged between the operating handle of the machine and the drive wheel axis. Here, too, the lowering movement of the tongs therefore takes place in a circular arc-shaped path.

Finally, Danish patent application no. 783/78 discloses a third related machine, in which the working cylinder is admittedly permanently vertical, but in which the collar arm is carried by a traction wire which is passed over a rope pulley arranged on top of the cylinder. This construction therefore has a greater machine height than lifting height. The movement of the tongs takes place without undesired great friction.

The object of the invention is to provide a machine of the type indicated, which at low construction height provides an approximately vertical path for the lowering movement 30 of the tongs with only small friction.

The tiling machine according to the invention is characterized by a substantially vertical spring rod in fixed connection with the frame arranged in the position of use, the upper free end of which carries a suspension bracket which receives the suspension axis for the collar arm.

That the intended vertical path of movement of the pliers is obtained can best be explained in connection with the drawing, the only figure of which shows a preferred embodiment of - 2 -

the machine in question.

A consideration of the drawing shows that the free (left) end of the collar arm 2 entering the machine, viewed in isolation, will move closer to the machine's drive wheel (to the right) 5 by the lowering movement of the collar arm. However, this movement is compensated by the opposite directional movement of the collar axis suspension axis 20.

In addition, it is noted that the heavy parts of the machine are advantageously arranged just above the driving wheel, while in the cases of the said German Patent Specification No. 2,241,503 they lie between the wheel axle and the operating handle.

The tiling machine shown in the drawing has a frame 1 with a pair of drive wheels 12.

A working cylinder 15 4 - with the piston 44 and piston rod 24 - and an auxiliary cylinder 3, which are connected to each other by means of a hose 11 with valve 7, are pivotally mounted on the frame. This valve is operated from the end of the frame 1 which is opposite the drive shaft 12, by means of a handle 8 and a valve rod 16.

The auxiliary cylinder 3 and the space under the piston 44 in the working cylinder 4 contain hydraulic fluid. The space above the hydraulic fluid in the auxiliary cylinder 3 contains air which can be put under a desired pressure through a valve 9 by means of a pump (not shown).

The free end of the piston rod 24 is in articulated engagement with the collar arm 2 and carries at the site of engagement a pair of guide rollers 10 which can move along a guide rail 21 which is in fixed connection with the frame 1.

The free end of the collar arm 2 carries over a wooden clasp 30 13 a tile tong 5,14,15 which functions in the same way as a brick rod.

..The. opposite..end. of the collar arm 2 is suspended as follows: In fixed connection with the frame 1 an approximately vertical spring rod 6 is arranged. Its free end 26 carries 35 a suspension bracket 27, the free end of which serves as a suspension axis 20 for the end of the collar arm 2.

The machine operates in such a way that when the tongs 14,15 have just released a tile F, the pressure in the auxiliary cylinder 3 will drive the tongs up into the highest position indicated by dotted lines (collar arm 2, cylinder 4), where the tongs 5 grip a new tile F at the top of a stack. The weight of the tile F will seek to lower the pliers to a low position, and this lowering movement can be regulated by operating the valve 7 by means of the handle 8.

You thus drive the tile F to 10 hanging in the pliers to a desired place, where you lower it to the ground.

Thanks to the movement of the collar arm 2 shown in the drawing, the lowering movement of the tile will be practically vertical.

It will be understood that the machine is not only suitable for tiles, but for all kinds of paving stones, here under curbs and building elements, especially concrete building elements.
