Claim 10

The combination of elements defined in claim 6, wherein each of said baffle means on said ring elements includes an annular rib having a downwardly sloping surface thereon for draining off liquid thereon.

Claim 11

The combination of elements defined in claim 6, including openings in the wall of the outermost one of said ring elements adjacent the stationary member on which it is mounted, for drainage of liquid therethrough.

Claim 12

The combination of elements defined in claim 8, including means cooperating with said openings to maximize drainage of liquid outwardly therethrough and minimize entry of liquid inwardly therethrough.

Claim 13

The combination of elements defined in claim 9 wherein said last named means comprises an outwardly and downwardly inclined surface associated with said openings.

Claim 14

The conbination of elements defined in claim 9 wherein said last named means comprises surfaces in said outermost one of said ring elements converging toward said openings from opposite sides thereof.

Claim 15

In a weighing scale having a housing, a movable weight sensing mechanism within said housing, and a loadcarrying member outside of said housing connected to said weight sensing mechanism, a liquid-repelling shield device between said housing and said load-carrying member, comprising, a. a skirted cover positioned above said housing, b. meanS mounting said cover on said weight sensing mechanism for movement therewith and with respect to said housing, c. means mounting said load-carrying member on said skirted cover for movement therewith, and, d. means providing multiple stage concentric baffles mounted on said housing and forming a labyrinth within the confines of said skirted cover to prevent the entrance of liquid into said housing.

Claim 16

In a weighing scale having a housing, a movable weight sensing mechanism within said housing, and a loadcarrying member outside of said housing connected to said weight sensing mechanism, a liquid-repelling shield device between said housing and said load-carrying member, comprising, a. a skirted cover positioned above said housing, b. meanS mounting said cover on said weight sensing mechanism for movement therewith and with respect to said housing, c. means mounting said load-carrying member on said skirted cover for movement therewith, and, d. means providing multiple stage concentric baffles mounted on said housing and forming a labyrinth within the confines of said skirted cover to prevent the entrance of liquid into said housing.

Claim 17

The combination of elements defined in claim 12, wherein said last named means includes a tubular member having a plurality of radially spaced annular walls, and an annular baffle member on at least one of said walls.

Claim 18

The combination of elements defined in claim 13, wherein each of said baffle members has a downwardly and outwardly sloping surface thereon for draining liquid therefrom.

Claim 19

The combination of elements defined in claim 14, combined with openings in the outermost wall of said tubular member through which liquid may drain from within said wall.

Claim 20

The combination of elements defined in claim 15, including means cooperating with said openings to maximize drainage of liquid outwardly therethrough and minimize entry of liquid inwardly therethrough.

Claim 21
