REPLOGLE, OIF DETROIT, IYIICCHIGAN, ASSGNOR TO KELVINATOR CORPORA- TION, 0F DETROIT, MICHIGAN, A CORPORATION 0F MICHIGAN l REFRIGERATEUR@ CABINET Original yapplication led August 25, 1924, Serial No. 733,913. Divided and this application filed February This invention relates to machinery supports, and more particularly to supports for the condenser unit and associated mechanism vof mechanical refrigerating apparatus, the

cito-pending application Serial No.v 733,913 1924. Application Serial No. 733,913 has resulted in .Patent No'. 1,716,150 issued January 4, 1929.

An object of the invention is the provision of mechanical refrigeration. apparatus having an improved mounting for the motor driven compressor designed to minimize noise incidentJ to vibration thereof.

Anotherobject of the invention Iis the provision of a resilient mounting for machinery which can be readily adjusted to permit accurate disposition ofthe machinery.

Other objects more or less incident to the foregoing will appear in the following de-` scription of the preferred embodiment of `the invention as shown in the drawings.

Referring in detail to the constructions illustrated, the frame of the cabinet, which `is preferably'made to a considerable extent of standard structural steel forms, is of the character as that illustrated in my pending application Serial No. 673,678 and includes longitudinally extending bottom members 1 and similar top members 2 and transverse bottom members 3. The

similar view of one of the Serial No. 255,244.

cabinet is divided by walls into a heat insulated refrigerated compartment 4 and a machinery containing compartment 5. An outer wall of the machinery compartment is closed by a removable plate 6 to provide access to the machinery, and also to allow assembly with and removal of the machinery from the cabinet. Metal blocks 7 are .preferably provided on the under side of the cabinet frame to suitably support it.

Suitable refrigerating machinery is arranged within the machinery compartment erence maybe had to my co-pending application herein referred to.l

To render the operation of the refrigerating mechanism as quiet as possible, I ha've devised an improved resilient mounting for the condenser unit. Two brackets or lugs are formed on the rear sides of the casings 8 and l0 and to them are secured depending stud bolts 11. On these studs is arranged an apertured bar 12 with coiled springs 13 surrounding :he studs between the bar 12 and the casing lugs and withI springs 14 surrounding the lugs between the lower sides of the bar 12 and the heads of the bolts.

The studs are fitted at'their upper and lower ends with thimbles 15 and 16 which serve to center the springs in relation to the studs and the apertures through the bar 12 are counterbored to yreceive and center the `adjacent ends of the springs. The apertures in the bar 12 are large enough to provide a clearance between it and thef studs. Bolts serve to rigidly connect the bar l12 to the floor 18 of the cabinet.

At the front side of the condenser unit two upright-studs 19 and 20 are rigidly secured to the floor 18 of the cabinet, and

on these studs is arranged an apertured ment which the unit with such a spring sushorizontal bar 21 with springs 22 surrounding the studs and interposed between the bar 2l and centering thimbles v23 which are adjustably' supported by nuts ,24 on the studs. Similarly springs 25 are interposed between the upper sidesof the bar 21 and centering thimbles 26 which engage abutment nuts 27 on the studs. The apertures through the bar 21 afford clearance around the studs 19 and 20 and arev counterbored (Fig. 5) tov receive and center the adjacent ends of springs 22 and 25. The front side of tHe gear casing 10 is formed with a bracket or lug 28 which rests upon and is rigidly bolted tothe bar 21. r

With the construction described, the springs of the suspensioncdevices yieldingly sup ort the condenser unit and yieldingly hold it against movement in all directions. That is to say, by the simple expedient of centering the coiled springs relative to the studs and providing clearance between) the studs and the apertured bars through which .f they pass, the plain and relatively inexpensive coil springs are enabled to afford a yielding and resilient support for the unit adapted to permit limited movement of the unit and in any and all directions. In mounting the condenser unit in its compart- `ment of the cabinet, the rear spring supports are preferably assembled on the unit while the front springsupportsare assembled on the floor of the cabinet. Then. when the unit is lifted intofposition in its com` partment it is necessary only to apply the two bolts 17 to secure the rear suspension rigidly to the cabinet floor and to apply the single bolt which secures the floor bracket' 28 of the-unit to the bar 21. When the unit has thus been placed in position in the cabinet the abutment nuts 24 and 27 of the Hoor spring suspension can be adjusted on their studs to level the unit and insure suitable clearancebetween it and the side walls of the' compartment. To permit-.the limited freedom of movepension must have, the refrigerant conduits 29, 30 and 31 are made sulliciently long and are suitably disposed so that they will readily flex enough to accommodate the vibratory movementsof the unit. The flexibility of the spring mounting, above described, is such that some means must be provided to secure the unit against undue movement and inury during shipment, and I provide the fo lowing simple means for that-purpose. As shown in Figs. 4 and 6 the rear spring studs 11 have their lower ends tapped toreceive the screws 32fwhich are extended upward through apertures in the underlying frame angle bar 33. By turning the screws 32 the ends of the Studs 11 and drawn down to Afirm engagementv with the angle bar 33,

thus rigidly securing the condensing unit at its lrear side. The front side of the unit is secured to the cabinet frame and casing structure by introducing a spacersleeve 34 (Fi 5)` between the bar 21 and the Hoor of t eJ cabinet and inserting securing bolt 35, the bar 21.and the floor being apertured to receive said bolt. These securing devices are very readily applied and detached and serve when applied to safely hold the condenser unit "against dangerous movement during shipment.

Fig. 7 indicates a slight modification of the rear securing device illustrated in Figs. 4 and 6. In this modification, by simply introducing a spacer 36 between the` head of the stud 11 and the angle plate 33 the screw 32 serves to -rigidly secure the stud to the plate Without materially compressing the springs 13. y In Fig. 8 is shown another modification in which ,the lower end of a modified stud 37 is formed with a threaded extension 38 which projects through the aperture of the angle plate 33 and is adapted to be engaged by a nut 39 to draw the stud down until its head engages with the plate 33.

In the operation of the refrigerating mechanism extreme quietness is secured by the spring suspension of the condensing unit because thel amount of vibration transmitted from the unit to the cabinet walls is practically nil.

While I have shown and described the preferred constructions embodying my improvements it will be understood that the constructions illustrated can be more or less widely varied without departing from the invention, the scope of which is indicated by the appended claims.

What I claim is:

1. A resilient suspension device comprising, a supporting member and a frame member, a stud bolt having an intermediate portion loosely mounted in one of the members,

.a resilient element associated with each end -of the stud bolt, means for retaining the resilient elements in operative relation between themember and the ends of the stud bolt, means for securing one end of the stud bolt rigidly to theother member, and means for securing the members rigidly together to render the suspension non-resilient. l

2. A resilient suspension'device comprising, a supporting member and a frame member, a stud bolt having an intermediate por- .tion loosely mounted in one of the members,

securing the members rigidl render the suspension non-resi ient.

3. A resilient suspension device comprising, a sup ortin member and a frame memf ber, a stu bolt aving an intermediate portion loosely mounted in one of the members, a resilient element associated With one end of the stud bolt, means for retaining the resilient element in operative relation between the member and the end of the stud bolt, means for securing the opposite end of whereof I hereunto aix my signature.
