Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
172 words
In a building construction having a continuous footing and a plurality of post-type footings, each of said footings having a top face, and a wooden lower structure erected on the footings, the improvement wherein the top faces of the footings are provided with an upwardly opening groove therein, an upwardly opening tray positioned within the respective grooves accommodating therein a wood preserving and insecticidal liquid, said tray being formed by walls which are impervious to said liquid to prevent same from permeating into the footings, a plurality of pipes interconnecting the trays which are mounted on the different footings to permit transfer of said liquid between said trays, and suction material affixed to at least a portion of said lower structure, at least a part of said suction material being positioned within the trays and being in contact with the liquid therein, whereby said suction material sucks up the liquid in said trays and transfers same to said lower structure so that the liquid can permeate the lower structure to protect same.
Claim 2
Dependent Claim
172 words
In a building construction having a continuous footing and a plurality of post-type footings, each of said footings having a top face, and a wooden lower structure erected on the footings, the improvement wherein the top faces of the footings are provided with an upwardly opening groove therein, an upwardly opening tray positioned within the respective grooves accommodating therein a wood preserving and insecticidal liquid, said tray being formed by walls which are impervious to said liquid to prevent same from permeating into the footings, a plurality of pipes interconnecting the trays which are mounted on the different footings to permit transfer of said liquid between said trays, and suction material affixed to at least a portion of said lower structure, at least a part of said suction material being positioned within the trays and being in contact with the liquid therein, whereby said suction material sucks up the liquid in said trays and transfers same to said lower structure so that the liquid can permeate the lower structure to protect same.
Claim 3
Dependent Claim
38 words
A construction according to claim 1, wherein said suction material comprises a sheetlike fibrous material which is affixed to the lower structure and which hangs downwardly from said lower structure into said trays for contact with the liquid.
Claim 4
Dependent Claim
140 words
In combination, a horizontally elongated footing for a building, said footing having a top face, and a wooden lower structure for a building erected on the top face of said footing, the improvement wherein an upwardly facing groove is formed in the top face of said footing accommodating therein a wood preserving and insecticidal liquid, said groove extending longitudinally of the footing and being formed by walls which are impervious to said liquid so as to prevent the liquid from permeating into the footing, and suction material affixed to a least a portion of said lower structure and projecting into said groove and being in contact with the liquid therein, whereby said suction material sucks up the liquid in said groove and transfers same to said lower structure so that the liquid can permeate the lower structure to protect same.
Claim 5
Dependent Claim
140 words
In combination, a horizontally elongated footing for a building, said footing having a top face, and a wooden lower structure for a building erected on the top face of said footing, the improvement wherein an upwardly facing groove is formed in the top face of said footing accommodating therein a wood preserving and insecticidal liquid, said groove extending longitudinally of the footing and being formed by walls which are impervious to said liquid so as to prevent the liquid from permeating into the footing, and suction material affixed to a least a portion of said lower structure and projecting into said groove and being in contact with the liquid therein, whereby said suction material sucks up the liquid in said groove and transfers same to said lower structure so that the liquid can permeate the lower structure to protect same.
Claim 6
Dependent Claim
51 words
The combination of claim 3, wherein the walls of said groove are formed by an upwardly opening tray which is separate from said footing, and a portion of said tray projecting to the outside of the footing to form a supply hole for permitting replenishment of the liquid in the tray.
Claim 7
Dependent Claim
33 words
The combination of claim 3, including means communicating with said groove and projecting outside of the footing so as to define a supply hole which permits replenishment of the liquid within the groove.
Claim 8
Dependent Claim
107 words
The combination of claim 3, wherein the footing includes a higher outer footing portion and a lower inner footing portion which are disposed directly adjacent one another and formed as an integral unit, said groove being provided in the respective top face of both the inner and outer footing portions, and said suction material having one part thereof positioned within the groove formed in the outer footing portion and another part thereof positioned within the groove formed in said lower footing portion, said parts of the section material being joined by a further part which extends between the grooves formed in the outer and inner footing portions.
Claim 9
Dependent Claim
39 words
The combination of claim 3, wherein said footing has transverse ventilation grooves formed across the top face thereof, said ventilation grooves being shallow in contrast to the depth of said liquid-containing groove so as to permit proper ventilation thereof.
Claim 10
Dependent Claim
64 words
The combination of claim 3, wherein said suction material comprises a sheetlike fibrous material which is affixed to the lower structure over a long extent thereof, a part of said fibrous material projecting down from said lower structure so as to hang into the groove over a substantial longitudinal extent thereof to permit the liquid to be sucked up by the sheetlike fibrous material.
