Abstract
Abstract An elongated, open-topped bucket has a trapezoidal cross-section, with the smaller base below. The bottom of the bucket has an elongated slit into which wallpaper may be introduced. A flexible lip inside the bucket guides the wallpaper up against the rear wall of the bucket and prevents paste in the bucket from leaking out the bottom. At the top of the bucket are a skimming blade and a corrugated raking blade that cooperate to remove all but the proper amount of paste from the wallpaper as the wallpaper is withdrawn from the top of the bucket. The blades are spring loaded against the wallpaper and are independently spring loaded.

Claim 1
Independent Claim
316 words
A device for applying paste to wallpaper, comprising: an open-topped elongated bucket with a trapezoidal cross-section, with the large base of the trapezoidal being upwardmost and the bottom of the bucket having an elongated slit for introducing a strip of wallpaper into the bucket from the bottom; guide means including a flexible elongated sealing lip located in the bottom of the bucket for allowing paper to be introduced into the bucket while preventing any fluid contents of the bucket from leaking downwardly out of the slit and said flexible lip maintaining the wallpaper onto the rear wall of the bucket; so that paste is applied to only one surface of said wallpaper; scraping means located at the top of the bucket for scraping all but a predetermined amount of any contents of the bucket from said one surface of the paper; said scraping means comprising a. a first blade at least co-extensive with the width of said surface and fixed to the end of at least one horizontally extending threaded rod passing freely through the bucket wall remote from said surface, b. resilient means mounted on said rod and biasing said rod and blade into operative contact with said surface, c. a threaded adjustment nut on said rod and cooperative with said bias means whereby to vary the bias pressure, d. a second blade at least co-extensive with the width of said surface and supported from an intermediate portion of said rod, e. second resilient means mounted on said rod and biasing said second blade into operative contact with said surface, and f. a second nut on said rod and cooperative with said second resilient means to vary the bias pressure on said second blade, whereby said blades are separately adjustable and adapted to function sequentially to first remove the major amount of excess paste and finally doctor said surface to said predetermined amount of paste.
