DMTWUIT, MIT-m application filed January it, that. dental lli'o. tttllt.

This invention relates to resilient supports and more particularly to a support or suspension means designed for use I in connection with mechanical refrigtrating apparatus for supporting the power uhit thereof whereby the vibrations emanating from the moving parts thereof may be absorbed and transmission of the same to the refrigerator or other associated. structure prevented.

Tn mechanical refrigeration it is customary to provide a power unit such for instance as an electric motor together with a compressor or pump and a rotor such as a fan and to as sociate this mechanism with a refrigerator 115 box or the like. The vibrations set up by the movement of the parts inoperation are, in the case of a direct or rigid mounting of these parts, transmitted directly to and throughout the refrigerator box and prove noisy and othl erwise objectionable. Many means have been attempted for dissipating or otherwise absorbing thesevibrations so as to prevent their transmission to the refrigerator box, but these heretofore known devices have so far proven to be-either complicated, relatively crude, in-

. efficient or otherwise unsatisfactory.

Tt is therefore the primary object of this invention to provide a resilient support or mounting for the operating mechanism of a to mechanical refrigerator and vide a support of this character which is dis tinguished by its simplicity, efficiency and cheapnessin manufacture and installation. Various other objects, advantages and 35 novel details of construction of the invention will be made more apparent as this description proceeds especially whenconsidered' in connection with the accompanying drawings, wherein to m Figure. 1 is a fragmentary elevational view of a refrigerator box showing the operating mechanism for producing mechanical refrigeration and showing the application of my invention. I v Figure 2 is a plan view of a base or support forming a part of the herein described invpntion.

showing a modified form of construction.

Referring now more particularl to the drawings wherein like reference 0 aracters further to proenlarged fragmentary sec- 1 indicate like parts it will be noted that in Figure 1 l have shown fragmentarily a refrigerator box 10 adapted to be electrically refrigerated, the lower portion of the box being provided with a compartment 11 provided with a bottom 12. It is Within the com- 1 part-me-nt 11 that I propose mounting the mechanism for producingmechanical refrig oration and in which the support constituting this invent-ion is disposed. l have shown in conventional form only a power unit such as an electric motor 13 having a driving connection with a compressor or pump. 14 together with a fan 15 and a condenser 16. In practice these parts are mounted upon a base 17.

ln carrying out this invention l preferably 7 employ a supplemental base 18 formed preferably, although not necessarily, of wood,

bolted or otherwise secured at a plurality of points as indicated at 19 to the'bottom 1 2 of the refrigerator box. This supplemental base is formed with a plurality, here shown as three, suitably spaced pockets or recesses 20.

The base 17 which directly supports the refrigerating mechanism is provided with a corresponding number of threaded apertures W 21, in which are inserted threaded pins or studs 22. The lengthof these pins 22 is so selected as to be less than and to be housed within the customary peripheral flange 23 on the base 17. Each stud 22 has fixed thereto a coil spring 24 which is adapted to surround the associated stud 22 and to project beyond the end thereof and into the-associated pocket 20 of the supplemental base 18. The length and strength of the springs M is soselected to that they will support the base 17 spaced from the supplemental base 18 as suggested in Figure 3. lllith' such an arrangement vibrations or other shocks emanating from the moving as parts supported upon the base 17 are dissipated and absorbed bycthe springs 24: to prevent their transmission to the supplemental base 18-and consequently to the refrigerator, box. 7 too In Figure 4 T have shown the base 17 as provided with feet or legs 25 secured to the under side thereof. The lower end of each leg 25 is provided with a threaded aperture 26 adapted to be engaged by the threaded portion of a threaded pin or stud 27 to which a spring 28 is attached. With such a construction the base 17 may be supported directly upon the floor or upon a suitable portion of the refrigerator box and the vibrations set up by the moving parts supported upon the base 17 will likewise be absorbed or dissipated by the springs 28. Y

It will be readily apparent that While I have illustrated an embodiment of the invention in which a supplemental base 18 is utilized, that this supplemental base may be eliminated and the base 17 supported directly by the springs 24 upon the floor 12 of the refrigerator box which latter part may or may not be formed with the recesses or pockets 20. However, with the embodiment of the invention shown in Figures 1 to the supplemental base may have the recesses 20 properly located therein at the factory and either bolted to the refrigerator box at the factory or sent separately to the distributor or user with instructions for attachment to the refrigerator box in which the electrical refrigerating apparatus is to be installed. In such an instance the properly spaced pockets not only insurev a correct positioning of the base and the parts carried thereby, once the supplemental base has been correctly placed, but also prevents any accidental laterally shifting of the base 17 in use.

The threaded studs 22 may be quickly and easily removed or replaced should they become worn or broken or additional points of support may be provided merely by forming ad itional threaded apertures in the base 17 and inserting the threaded studs provided with the springs 2 1 in the threaded apertures.

The invention therefore is distinguished by its simplicity, efliciency and adaptability in practice thereby making the same commercially satisfactory and acceptable.

WVhile the invention has-been described herein somewhat in detail it will be readily apparent to those skilled in this art that various changes and modifications may be resorted to without departing from the spirit and scope of this invention and to this end reservation is made to make such changes as may come within the purview of the accompanying claim.

\Vhat I claim as my invention is:

A support having a base, a supplemental base detachably secured to said base having a plurality of spaced recesses therein, a third base constituting a support for mechanical refrigerating apparatus positioned substantially above the supplemental base and having a depending flange, members threadedly engaging said third base and extending downwardly therefrom terminating short of said supplemental base and concealed by said depending flange, and yieldable elements surrounding the members and engagin said recesses for yieldably supporting the third base spaeedfrom the supplemental base.

In testimony whereof I aiIix my signature.
