Abstract

A mount for a compressor or the like which sits on a base includes a top surface which is securable to the base. The top surface defines a well having a floor. An opening is formed in the bottom of the floor and a shaft extends from beneath the well floor to above the upper surface. The shaft includes a lower flange positioned below the well floor and an upper flange positioned above the top surface. A spring is positioned between said well floor and the top flange to absorb vibrations and any resulting shock produced by the compressor. A pair of upwardly extending generally perpendicular walls are provided on the upper surface to prevent the spring from engaging the upper surface or deflecting excessively. The walls and the upper flange are sized such that when the shaft moves with respect to the well, the upper flange will contact the wall before the spring contacts the upper surface or deflects excessively.

Claims

1. A mount for a device which sits on a base, the mount being securable to the base and the device sitting on the mount, the mount including:

a top surface which is securable to a base and defining a well having a floor, said well floor defining an opening;

a pair of generally perpendicular walls extending upwardly from said top surface;

a shaft received in said well and extending through said well floor opening and above said upper surface, said shaft including a lower flange forming means position below said well floor and having a diameter greater than said hole, an upper flange positioned above said top surface and having a diameter greater than said well, and a spring position between said well floor and said top flange;

means for securing said device to said mount above said top flange; and

said shaft defines an upper shoulder and includes an upper, threaded end extending above said upper shoulder, said upper flange comprising a washer means which sits against said upper shoulder and is held in place by a threaded means.

2. The mount of claim 1 wherein said shaft defines a lower shoulder and includes a lower, threaded end extending below said lower shoulder, said lower flange comprising a washer which sits against said lower shoulder and is held in place by a threaded means.

3. The mount of claim 1 wherein said upper flange includes a threaded means.

4. The mount of claim 1 wherein said mounting means includes said upper threaded end, said upper threaded end being received in said device;

said device being secured thereto.

5. The mount of claim 1 wherein said well includes a wall which surrounds said well floor hole, said wall, in conjunction with the wall defining said well, defining a channel.

6. The mount of claim 5 wherein said spring has one end received in said channel.

7. The mount of claim 6 wherein said spring is conical and spiral.
