Claim 14

The assembly of claim 1 further comprising: a. means projecting downwardly from a lower surface of said actuating means for engagement with a bottom of said groove to resist said movement of said actuating means longitudinally of said groove.

Claim 15

The assembly of claim 1 further comprising: a. means projecting upwardly from a bottom of said groove for engagement with a lower surface of said actuating means to resist said movement of said actuating means longitudinally of said groove.

Claim 16

The assembly of claim 14 further comprising: a. means projecting downwardly from a lower surface of said actuating means and cooperating with said upwardly projecting means on said bottom of said groove to resist said movement of said actuating means longitudinally of said groove.

Claim 17

An adjustable sill and threshold assembly comprising: a. a stationary sill including a molded base having a downwardly and outwardly sloped tread portion and a threshold groove having inner and outer walls extending longitudinally of said base adjacent an inner edge thereof, b. means defining a plurality of discrete, undercut sections in said inner wall of said threshold groove, c. means defining a plurality of drainage channels in said tread portion of said base extending downwardly and outwardly from said outer wall of said threshold groove to an outer edge of said tread portion, d. metal cladding covering an upper surface of said threshold portion of said base and extending around said outer edge of said tread portion in spaced relationship thereto and defining therewith a collection channel communicating with lower ends of said drainage channels, e. an inner edge of said cladding terminating in a substantially U-shaped section positioned in said threshold groove and including a leg projecting upwardly from said groove, f. a threshold having a cap portion overlying said threshold groove, an inner leg extending downwardly from said cap portion in contiguous relationship to said inner wall of said groove, and a pair of legs extending downwardly from said cap portion adjacent said outer wall of said groove and straddling said upwardly projecting leg of said U-shaped portion of said claddIng to define therewith a labrynth seal, g. a plurality of actuators received in said groove at said undercut sections thereof for limited sliding movement longitudinally of said groove in the vicinity of said undercut sections, h. outwardly projecting flange means on said actuators underlying said U-shaped portion of said metal cladding to restrain said actuators against vertical movement within said groove, i. tool engaging portions formed on said actuators projecting upwardly therefrom adjacent said inner wall of said groove and accessible by a tool inserted beneath said cap adjacent said inner wall of said groove, j. said tool engaging portion having a shoulder portion thereon cooperating with a shoulder defined by said undercut section of said groove to restrain vertical movement of said actuator within said groove, k. inclined ramp means projecting inwardly from legs of said threshold in opposition to each other, l. complementary inclined ramp means on said actuators in slidable engagement with lower surfaces of said inclined ramps on legs of said threshold, and m. outwardly projecting ears on said actuators extending outwardly over said upper surfaces of said ramps on said threshold and preventing separation of said actuators from said threshold.

Claim 18

An adjustable sill and threshold assembly comprising: a. a stationary sill including a molded base having a downwardly and outwardly sloped tread portion and a threshold groove having inner and outer walls extending longitudinally of said base adjacent an inner edge thereof, b. means defining a plurality of discrete, undercut sections in said inner wall of said threshold groove, c. means defining a plurality of drainage channels in said tread portion of said base extending downwardly and outwardly from said outer wall of said threshold groove to an outer edge of said tread portion, d. metal cladding covering an upper surface of said threshold portion of said base and extending around said outer edge of said tread portion in spaced relationship thereto and defining therewith a collection channel communicating with lower ends of said drainage channels, e. an inner edge of said cladding terminating in a substantially U-shaped section positioned in said threshold groove and including a leg projecting upwardly from said groove, f. a threshold having a cap portion overlying said threshold groove, an inner leg extending downwardly from said cap portion in contiguous relationship to said inner wall of said groove, and a pair of legs extending downwardly from said cap portion adjacent said outer wall of said groove and straddling said upwardly projecting leg of said U-shaped portion of said claddIng to define therewith a labrynth seal, g. a plurality of actuators received in said groove at said undercut sections thereof for limited sliding movement longitudinally of said groove in the vicinity of said undercut sections, h. outwardly projecting flange means on said actuators underlying said U-shaped portion of said metal cladding to restrain said actuators against vertical movement within said groove, i. tool engaging portions formed on said actuators projecting upwardly therefrom adjacent said inner wall of said groove and accessible by a tool inserted beneath said cap adjacent said inner wall of said groove, j. said tool engaging portion having a shoulder portion thereon cooperating with a shoulder defined by said undercut section of said groove to restrain vertical movement of said actuator within said groove, k. inclined ramp means projecting inwardly from legs of said threshold in opposition to each other, l. complementary inclined ramp means on said actuators in slidable engagement with lower surfaces of said inclined ramps on legs of said threshold, and m. outwardly projecting ears on said actuators extending outwardly over said upper surfaces of said ramps on said threshold and preventing separation of said actuators from said threshold.
