Description

DEVICE FOR LEGS OF THE LIKE well known that machines for building are to be operated frequently on wet and muddy obtain a steady building to be supported on muddy are generally provided on their legs with horizontal supporting plates for two to prevent on the one hand the sinking of the leg nto the muddy and to prevent on the other hand a lateral slipping of the The supporting plates diminish the specific surface pressure exerted by the weight and the operation of the wedges or the like are mounted on the underside of the supporting penetrate Into the soil prevent a lateral slipping of the Supporting plates of this are adapted to fulfill the above mentioned purposes in case the building machine operates that means it remains essentially on the same place during its whole But in case of mobile machines which have to be moved frequently from one place to for example the legs and supporting plates have to be lifted with each move and the sticky adheres to the underside of the forming thus preventing at the redeposltlon of the legs and plates a steady support of the It Is the object of the present invention to produce a supporting plate which avoids the above mentioned disadvantages by simple According to the invention the device consists of a horizontal portion and a firmly closed at its whole the hand being provided with a portion fixedly oonnected to the upper rim of for example by and covering only partly the opening formed by the construction of the supporting device has the following The respectively the penetrate the soil at the deposition of the supporting device and secure thereby the against lateral The horizontal portion prevents a deep of the operation of the the supporting device repeatedly the sticky adheres to the vertical portions of the but at repositioning the leg on the soil the adhering pushed upwardly and falls thus the supporting device according to the Invention has a self cleaning Some embodiments of the will now be described in a non limitative fay reference the attached drawings show 1 A supporting plate lateral 2 A plan view of the supporting devic Schematic drawings of other embodiments of the Invention plan For clearness sake the legs and the building machine are not these not being object of the The shown being adapted to be mounted on the lower part of the leg of a consists of horizontal portion 1 and a like band around whole The band in the embodiment is welded of four shaped steel Band 2 substantially slightly The width of 2 1B reduced at 3 such a way that a contour s formed at lower Spikes which project are mounted the four comers of the The plate like portion of the supporting device le mounted on upper of band 2 and fixedly by Portion 1 also substantially square lies substantially concentric relative band 2 and connected thereto such a that the opening of band 2 s only partly covered by plate the embodiment shown Fig 2 this has been achieved thereby that the two squares being approximately equal in size are offset one relative the other at an angle of about fixing the supporting device to a of machine flanges are provided the upper surface of plate The plane formed by the width of band 2 is normal relative plate 1 but the plane of frame formed by band 2 parallel to plate Band 2 may be shaped otherwi se than square fo example rectangular or polygonal and plate 1 may be shaped accordingly for example circular or elliptical as shown in 4 and 5 is not essential that 1 pro jects laterally over band but may be mounted on the of band 2 the manner in insufficientOCRQuality
