Abstract
Abstract An electrically-driven portable surface-treating machine having the motor and means driven thereby for oscillating a platen mounted within a clamshell housing. The oscillatable platen is connected to the housing through securement of a plurality of resilient posts connected to the housing. The posts are formed with flanges which are retained within the recesses formed transversely in the housing and there are pairs of such posts at respective ends of the housing, a flange of each pair of posts being in abutting relationship. The posts are molded in a one step operation with a hollow body portion extending from the flange downwardly and being shaped adjacent the bottom of the hollow to receive a nut which is subsequently inserted from the open top of the body portion to nest adjacent to the bottom of the post. After the posts are disposed in the housing, screws will be threadedly connected to the nut to thus secure the platen at the bottom of the posts.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
193 words
A support assembly for an electrically-driven surfacetreating machine in which the motor and means driven thereby for oscillating a platen are mounted in a clamshell housing having a first and a second complementary segment, the support assembly comprises: a. a plurality of resilient posts including a hollow column terminatinng in a substantially perpendicularly extending flange, b. the hollow column having an internally extending shoulder formed adjacent the bottom thereof, c. a nut insertable into the column to nest upon the shoulder, d. a plurality of recesses formed in the segments of the housing extending in aligned pairs transversely disposed on either side of the clamshell housing, e. the flanged end of one of the posts is disposed in each of the recesses to place the posts in pairs connected to opposite segments of the clamshell housing whereby the flanged ends will abut each other to hold the posts securely within the recesses, and f. a plurality of screw means passing through the platen to secure the same to each of the resilient posts by treadedly engaging the nut whereby the platen and housing will be resiliently connected to permit the platen to oscillate.

Claim 3
Dependent Claim
70 words
The combination claimed in claim 1 wherein: a. the post has a central aperture with aan upper section of largest diameter, an intermediate section of intermediate diameter and a lower section of smallest diameter, b. an upper shoulder formed at the bottom of the upper section, c. a lower shoulder formed at the bottom of the intermediate section, and d. the nut nests on at least one of the shoulders.
Claim 4
Dependent Claim
43 words
The combination claimed in claim 2 wherein: a. the nut having a body, b. a flange extending from the body, and c. the flange to engage one of the shoulders to limit the insertion of the nut within the aperture of the post.
Claim 5
Dependent Claim
41 words
The combination claimed in claim 3 wherein: a. the flange formed on the upper end of the body of the nut, and b. the flange to engage the upper shoulder upon the nut being inserted into the aperture of the post.
Claim 6
Dependent Claim
57 words
The combination Claimed in claim 4 wherein: a. the body of the nut to be in spaced relation to the lower shoulder upon insertion of the nut within the aperture whereby on tightening of the screw within the nut, the nut to be forced increasingly downwardly to seat the bottom of the body upon the lower shoulder.
Claim 7
Dependent Claim
40 words
The combination claimed in claim 2 wherein: a. the nut having a body shaped hexagonally, and b. the intermediate section of the aperture hexagonally shaped corresponding to the nut body and adopted to receive the same in non-turning engagement therewith.
