I In Germany December 9, 1935 1 Claim.

This invention relates to a device for mounting apparatus on columns, in which the apparatus to be mounted is fixedly secured to a part which rests with its one end against the column and is pressed against said column by means of a band placed around the column. Such arrangements have already become known. These devices are designed in the manner of a band shell in which the band forms a closed figure. The ends of the band overlap each other, and are drawn towards the part carrying the actual apparatus, by means of a screw. In such arrangements the disadvantage exists that in order to remove the apparatus the screw must be completely removed.

Inaccordance with our invention it is therefore proposed to design the device in such a manner that simply by loosening up a screw the said device can be dismounted without completely unscrewing the screw.

Further advantages of the invention will become apparent to those skilled in the art as the description thereof proceeds. For a better understanding of the invention, however, reference is made to the accompanying drawing in which:

Fig. 1 is a top view, broken off, of an embodiment of the invention as applied to a vertical column,

Fig. 2 is a and,

Fig. 3 is an end view of the device of Fig. 1 showing the supporting beam in section.

Numeral l is the column assumed to be circular in this example, and onto which the apparatus is to be mounted. The apparatus is preferably fixedly secured to the beam 2 by screw connections through holes H or the like, the said beam having a U-shaped cross section. At the end of the beam 2 which rests against the column I, a second U-shaped piece 3 is so placed over the beam 2 (see Figure 3) that a hollow body having a rectangular profile is thereby formed. The two opposite long sides of the rectangle are formed into cutting edges, thus providing an unobjectionable support for columns having difierent diameter..

The two U-shaped pieces 2 and 3 are riveted at the

places

5 and 6 to an intermediately dis- This block thus lies between the legs of the U-shaped beam 2. It has a tapped bore in which a screw 1 is fitted. The head of the screw has a slot so that the screw can be handled with a screw driver. At the head a disk 8 is fastened which can turn with respect to said head, said disk having two lateral hookshaped extensions 9.

The hooks engage apertures I3 in a band III which embraces the column I. By turning the front view of the device of Fig. 1

screw 1 the loop formed bythe band can be increased or decreased at will. In this way it is possible to press the beam 2 firmly against the column i. The ends of the band l0 are in a protected position in the inner space of the U- shaped beam 2.

In order that the arrangement may be used on columns having greatly varying diameters without the necessity of making the screw 1 very long, the band ID has on both ends a large number of openings 13 in which the hooks 9 engage.

A cotter pin disk I2 engaging in an annular groove of the screw 1 serves for fastening the disk 8 to the screw 1.

In order that the band be tightened up when turning the screw in clockwise direction, the screw 1 has a left hand thread.

The mounting is simply carried out by holding the beam against the column to be used for the mounting, then placing the band about the column and hooking it with two of its openings in the hooks 9. Then by turning the screw the beam can be pressed against the column. Hence in order to loosen the connection the screw needs simply be loosened up, but without the necessity of completely removing the screw.

The construction is however not limited to the example described. Thus more especially the disk 12 and the band I0 may be designed differently. The band l0 may be provided for instance in the manner of a saw blade, and the disk 8 may have corresponding projections engaging therewith.

Having described our invention, what we claim and desire to secure by Letters Patent is:

A device adapted for mounting apparatus on columns in which the apparatus to be mounted is fixedly secured to a U-shaped beam resting with one of its ends against the column comprising, means for pressing the end of said beam towards the column, said means including a band embracing said column, a block member mounted near the end of said beam, a screw fitted into said block and means mounted on said screw for gripping said band, said band being adapted to be tightened to thereby press the end of said beam towards the column by turning said screw in one direction, turning the screw in the other direction being adapted to loosen the band and permit adjusting the U-shaped beam member on the column, a second U-shaped member mounted near the end of the beam which is resting against a column, said second U-shaped member cooperating with the first to form an enclosure, said block being mounted within said enclosure and attached to both U-shaped members.
