This invention'relatesto lfastenings for business machin-es such as typewriters, gadding Vmachines .and fthelike. l

'Numerous fastening udevices ihaa/e her-ete'iere been proposed for "business machines 1but Inone of these 'have-proven-wholly satisfactory. The fastenings heretofore available, in many instances, contributed to the transmission of noise, or were lacking in strength or were lacking in adaptability to the Various' machines and desks available, or were unsuited for shifting of the machine to other locations, or had other objectionable features.

In accordance with the present invention a fastening for business machines is provided which reduces the noise transmitted from the machine, prevents sounding board effects of the desk, table or other support, while at the same time is simple and rugged in construction.

In accordance with the present invention also a fastening for business machines is provided which is particularly adapted for the movement or shifting of the machine from one location to another as desired while at the same time providing adequate support and clamping of the machine at each location.

The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming partl hereof, in which:

Figure 1 is a vertical sectional view taken approximately on the line I-I of Fig. 2 and showing the manner of connecting the fastening and a business machine;

Fig. 2 is a plan View of the fastening with the machine removed;

Fig. 3 is a view similar to Fig. 2 showing the manner in which one portion of the fastening is slidable with respect to the other for shifting the machine to another location;

Fig. 4 is a Vertical sectional view taken approximately on the line 4 4 of Fig. 2; and

Fig. 5 is an enlarged fragmentary vertical sectional view taken approximately on the line 5-5 of Fig. 2.

It should of course be understood that the description and drawing herein are illustrative merely, and that various modications and changes may be made in the structure disclosed without departingm from the spirit of the invention.

Referring more particularly to the drawing a support is illustrated generally at I0, upon which a business machine, such as a typewriter, adding machine, or the like, having Ya fra-me portion dil, is adapted to be secured. The support It be a table, -or may ibe fthe typewriter :supporting portion -of a typewriter desk of the type which is adapted to be tilted to an inclined portion or of the type which is adapted to be swung .to a vertical position for storage of the typewriter or the like when the same is not in use. The support III may be of wood, metal or the like.

The fastening proper is preferably made in two sections, one of which, is a central section I2 and is adapted to be permanently mounted or secured rigidly in position on the support I0 by means of screws I3 or the like, which extend into the support I0. The screws I3 may be surrounded by spacer washers I3 of rubber or the like.

The central section I2 preferably consists of an upper iiat plate portion I4, preferably of sheet metal, with parallel side walls or edges I5 inturned at an acute angle. A pad I6, preferably of hair felt, rubber or similar resilient shock absorbing and sound deadening material, is provided of a thickness such as to space the lower extremities of the edges I5 from the support I 0. The pad I6 is preferably secured to the underface of the plate portion I4 by means of a suitable adhesive. The central section I2 also has a front edge portion I1 which is angularly inturned.

The fastening also includes an outer section I8 upon which the frame II of the machine is mounted and secured in position in any suitable manner, such as by screws I 9 extending upwardly through openings 20 and into bosses 2l in the frame I I.

The outer section I8 preferably consists of an upper at plate portion 22, preferably of sheet metal with outer parallel downwardly extending side edges 23 and a downwardly extending front edge 24. The plate portion 22 is preferably provided with parallel inner walls or edge portions 25 angularly disposed with respect to the upper surface of the plate portion 22 and complemental to the side edges I5 of the central section I2 for sliding engagement along the lower faces of the edges I5.

The outer section I8 preferably also includes an angularly disposed edge portion 26 for contact with and engagement by the front edge portion I1 of the central Section I2. The outer section I8 preferably includes a pad 21, of hair felt, rubber or similar resilient shock absorbing and sound deadening material, and of a thickness to space the

edge portions

23, 24, 25 and 26 from the support I0, and resiliently support these edge portions.

The machine when secured to the outer section I8 may be readily slid therewith to position with the edges 25 of the outer section I8 in frictional engagement beneath the edges I5 and with the edge portion 26 of the outer section I8 in contact with the edge portion I1 of the central section I2. The machine will th'en be solidly supported. The pad 21 eflectually deadens any sound which might tend to be transmitted to the centra1 section I2 and the pad I6 is of further assistance for the same purpose. The pads 21 and I6 also prevent noise in the sections I8 and I2. The pads I6 and 21 also reduce or eliminate any sounding board effect of the support l0. At the same time the fastening is of adequate strength to support the machine Whether the support I0 is tilted or is moved to a vertical position. If desired also the machine may be readily removed with the outer section I8 secured thereto, by sliding the outer section I8 along the support I0 until the edge portions 25 are free from engagement with the edges I5. The machine and the outer section I8 may then quickly be mounted upon another central section I2 at some other location Where it is desired to use the same.

I claim:

1. A fastening for business machines comprising a central section adapted to be secured to a support and an outer section adapted to have a business machine secured thereto, and complemental side Walls on said sections for sliding nterlocking engagement, each of said sections having a pad of resilient sound absorbing material disposed thereunder for spacing said section and said walls from the support, said pads urging the side walls of the respective sections into engagement.

2. A fastening for business machines comprising a central section consisting of a at member of sheet material adapted to be rigidly secured to a support and having outer side walls inclined at acute angles with respect to said flat member, an outer section consisting of a second flat member of sheet material and having complemental inclined walls for engagement with said outer side walls, and each' of said sections having a pad of resilient sound absorbing material extending thereunder and in engagement with the under side of said flat member for spacing said section from the support, said pads urging the side Walls of the respective at members into engagement.
