Abstract

A motor mount adapter is disclosed which allows a blower housing to firmly hold a blower motor having a different size and shape than the blower motor originally designed to fit on the motor mounts and gaskets of the blower housing. The motor mount adapter has an outside surface which is shaped to mate with the surface of the motor mounts of the blower housing. If the motor mount surface has positioning holes, the outside surface of the motor mount adapter has projections which fit within the positioning holes to hold the motor mount firmly in place. The inside surface of the motor mount adapter holds gaskets which separate the blower motor from the motor mount adapter. When assembled, the blower motor of the blower assembly is supported solely by the gaskets on the motor mount adapter.

Claims

1. A motor mount adapter for a blower housing, said blower housing having motor mounts, comprising:

a pair of rigid adapter members;

each of said adapter members having a gasket mounting surface; and

each of said adapter members configured to couple to a motor mount of the blower housing to hold the adapter member in place against the motor mount during use.

2. The motor mount adapter for a blower housing as defined in claim 1 wherein each of said motor mounts has a positioning hole, and each of said adapter members has a projection from a surface of the adapter member which fits into the positioning hole of a motor mount.

3. The motor mount adapter for a blower housing as defined in claim 1 wherein each of said adapter members has a positioning hole, and each of said motor mounts has a projection from a surface of the motor mount which fits into the positioning hole of an adapter member.

4. The motor mount adapter for a blower housing as defined in claim 1 wherein each adapter member has ventilation slots.

5. A motor mount adapter for a blower comprising in combination:

a first housing member having a motor mount;

a second housing member having a motor mount, said second housing member configured to couple to the first housing member to form a blower housing;

a first adapter member having a gasket mounting surface, said first adapter member configured to couple to the motor mount of said first housing member;

a second adapter member having a gasket mounting surface, said second adapter member configured to couple to the motor mount of said second housing member;

gaskets positionable on the gasket mounting surfaces of the first and second adapter members;

a motor configured to be placed between the gaskets during use; and

a blower wheel configured to couple to a shaft of the motor.

6. The motor mount adapter for a blower as defined in claim 5 wherein said first and second adapter members have projections which fit into mating surfaces on the motor mounts of the first and second housing members.

7. The motor mount adapter for a blower as defined in claim 5 wherein said motor mounts of the first and second housing members have projections which fit into mating surfaces on said first and second adapter members.

8. The motor mount adapter for a blower as defined in claim 5 wherein said first adapter member is attached to the first housing member motor mount by fasteners placed through the first adapter member, and said second adapter member is attached to the second housing member motor mount by fasteners placed through the second adapter member.

9. The motor mount adapter for a blower as defined in claim 5 wherein the motor mounts of the first and second housing members have ventilation slots, and said first and second adapter members have ventilation slots corresponding to the ventilation slots in the first and second housing members.

10. The motor mount adapter for a blower as defined in claim 5 wherein said gasket mounting surfaces of the first and second adapter members have gasket positioning means for properly positioning the gaskets on the gasket mounting surfaces.

11. The motor mount adapter for a blower as defined in claim 10 wherein said gasket positioning means comprises a recess formed in walls of the first and second adapter members.

12. The motor mount adapter for a blower as defined in claim 10 wherein said gasket positioning means comprises a slot in walls of the first and second adapter members, and wherein said gasket has a projection which fits into said slot.

13. A method of positioning a blower motor in a blower housing wherein the blower motor is of a different size than the blower motor for which the blower housing was designed to hold comprising:

attaching a blower wheel to a shaft of the blower motor;

placing a gasket on a gasket mounting surface of a first motor mount adapter;

placing a gasket on a gasket mounting surface of a second motor mount adapter;

placing the first motor mount adapter on a motor mount of a first housing member of the blower housing;

placing the blower motor on the gasket positioned on the gasket mounting surface of the first motor mount adapter;

placing the second motor mount adapter on a motor mount of a top housing member of the blower housing; and

attaching the second housing member to the first housing member so that the motor is positioned between the gaskets on the gasket mounting surfaces of the first and second motor mount adapters.

14. The method of using a blower motor in a blower housing as defined in claim 13 further comprising:

holding the first motor mount adapter against the motor mount of the first housing member by a projection extending from the motor mount adapter into said motor mount.

15. The method of using a blower motor in a blower housing as defined in claim 13 further comprising:

holding the second motor mount adapter against the motor mount of the second housing member by a projection extending from the motor mount adapter into said motor mount.

16. The method of using a blower motor in a blower housing as defined in claim 13 further comprising:

holding the first motor mount adapter against the motor mount of the first housing member by a projection extending from said motor mount into the first motor mount adapter.

17. The method of using a blower motor in a blower housing as defined in claim 13 further comprising:

holding the second motor mount adapter against the motor mount of the second housing member by a projection extending from said motor mount into the second motor mount adapter.

18. A blower assembled according to the method of claim 13.
