Abstract
Abstract A spreader assembly adapted to be attached to a prime actuator for movement over a surface to uniformly spread a viscous material comprising an outer frame member of generally U-shaped configuration consisting of a center section and left and righthand wing sections pivotally connected to opposite terminal ends of the center section, said frame member including a first main support member and a first strip made of a flexible material depending from the first main support member to provide a flexible edge in contact with the surface, a wiping bar generally parallel to the center section and spaced therefrom consisting of a second main support member and a second strip made of a flexible material depending from the support member and a center divider extending generally perpendicular to the center section and mounted for angular adjusting movement relative thereto.

Claim 1
Independent Claim
171 words
A spreader assembly adapted to be attached to a prime actuator for movement over a surface to uniformly spread a viscous material comprising an outer frame member of generally Ushaped configuration consisting of a center section and left and right-hand wing sections pivotally connected to opposite terminal ends of the center section, said frame member including a first main support member and a first strip made of a flexible material depending from the first main support member to provide a flexible edge in contact with the surface, a wiping bar generally located forwardly of the center section of the outer frame member parallel to the center section and spaced therefrom consisting of a second main support member and a second strip made of a flexible material depending from the support member, a center divider pivoted to said section and extending forwardly and generally perpendicular to the center section and mounted for angular adjusting movement relative thereto, and means on said wiping bar supporting said divider for angular, vertical and horizontal adjustment.
Claim 2
Dependent Claim
171 words
A spreader assembly adapted to be attached to a prime actuator for movement over a surface to uniformly spread a viscous material comprising an outer frame member of generally Ushaped configuration consisting of a center section and left and right-hand wing sections pivotally connected to opposite terminal ends of the center section, said frame member including a first main support member and a first strip made of a flexible material depending from the first main support member to provide a flexible edge in contact with the surface, a wiping bar generally located forwardly of the center section of the outer frame member parallel to the center section and spaced therefrom consisting of a second main support member and a second strip made of a flexible material depending from the support member, a center divider pivoted to said section and extending forwardly and generally perpendicular to the center section and mounted for angular adjusting movement relative thereto, and means on said wiping bar supporting said divider for angular, vertical and horizontal adjustment.
Claim 3
Dependent Claim
45 words
A spreader assembly as claimed in claim 1 where each of said wing sections comprises an arcuate corner portion and a straight sided outwardly divergent terminal portion disposed at an angle of about 3 to 7* relative to a plane perpendicular to the center section.
Claim 4
Dependent Claim
42 words
A spreader as claimed in claim 1 wherein the center divider comprises two segments arranged so that it straddles the wiping bar and including means for selectively adjusting the height of the center divider relative to the spreader bar and main frame.
Claim 5
Dependent Claim
37 words
A spreader assembly as claimed in claim 1 including connecting meanS for pivotally connecting the spreader assembly to the prime actuator so that it may be selectively pivoted between a raised inoperative position and lowered operative position.
Claim 6
Dependent Claim
75 words
A spreader assembly as claimed in claim 4 wherein said connecting means includes a pair of spaced apart plate members connected to the main frame and the spreader bar assembly and an elongated bar carried by the plate members slidably mounting at opposite terminal ends adjustable tie rods secured at their outer ends to the cross wiper bar and compression spring circumscribing the tie rods to exert a downward leveling force on the spreader assembly.
Claim 7
Dependent Claim
33 words
A spreader assembly as claimed in claim 1 including roller support members mounted adjacent the outer terminal ends of the wing sections thereby to prevent the terminal ends from digging into the surface.
Claim 8
Dependent Claim
20 words
A spreader assembly as claimed in claim 4 wherein said connecting means includes level adjustment means for the spreader assembly.
Claim 9
Dependent Claim
39 words
A spreader assembly as claimed in claim 1 wherein the outer terminal ends of the wing sections are outwardly directed at an angle to a perpendicular plane to ensure proper flexing of the edge in contact with the surface.
