ADJUSTABLE SUPPORT FOR FALSE WORK FOR FLOORS.
Specification of Letters .Patent.
Patented July 2,1912.
Application filed March 19, 1912. Serial No. 684,772.
. To all whom "it may concern:
Be it known that I, PHILIPP ToELPE, a subject of the King of Prussia, German Emperor, residing at Magdeburg, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in an Adjustable Support for False Work for Floors, of which the following a specification.
This invention relates to an adjustable support for false work for floors in which an eccentric serving as locking device is arranged in the middle between two telescopic parts of the support. This device permits of obtaining a uniform tension for a great length of the two wooden parts which are in contact, by means of a comparatively little pressure so that the support is secured against displacement even under a considerable load. To prevent the eccentric from penetrating into the wood of the two parts of the support and in order to insure a uniform distribution of pressure, plates are inserted between the eccentric and the wood which have noses at their upper edge gripping over the band which embraces the connecting parts. In this manner an unintentional displacement of the strengthening plates is prevented. The strengthening plates are slightly conical and arranged in such a manner that the thickened part of the plates is at the side which is pushed between the wood and the eccentric in consequence of the turning of said eccentric. The conical shape of the lates prevents an accidental displacement of the plate even if the eccentric is tightened very much.
In the accompanying drawings the invention is shown by way of example Figure 1 is front elevation of the support.
Fig. 2 is a cross section of the same, and Fig. 3 shows on a larger scale and in cross section, a modified form of construction.
The lower support a has at its upper end a vertical slot 6 with which the locking device engages. This locking device is maintained upon the upper part 0 of the support and more particularly upon the arms (Z of said upper part which are connected by bands f, g. In the band 9 the looking device is mounted. It consists of -an axle h which has a square end is and upon which an eccentric Z is keyed which is flattened at its largest parts, that is, at the parts which bear against the clamping plates m when the eccentric is being operated. The clamping plates m are slightly conical in order to prevent an accidental displacement of the same, and they have noses m which grip over the band g. In order to prevent the turning of the clamping device when a very strong pressure is exerted the clamping plates m have small nipples n which serve as abutments and bear against the flattened parts of the eccentric, limiting thus the turning of the same. The bands 1", 9, can be fixed to the wooden support by means of screws. There could, however, be arranged wedge-shaped plates 0 which are inserted between the bands and the outer surface of the wooden support and which serve for readjusting the connection.
The device for re-tightening the connecting band can further consist in a wedge adapted to be moved upon a screw spindle as shown in Fig. 3. This screw spindle t which is mounted in the connectin band 9, carries a cone-shaped nut 42 WlllCll bears against the wedge-shaped clamping plates m and by turning the screw spindle t in the one or in the other direction the cone 1) can be moved so as to loosen or tighten the wedge-shaped clamping plates m.
