Abstract: There is provided a roller for inserting filler material to the proper depth in crevices comprising a circular structure having a central circular section of at least 1/16" of an inch thick but less than 1/4 of an inch thick, a first and second truncated right angle cone sections of a smaller diameter than said central circular section and appended on each side of said central circular section at its base line to which is attached a third or fourth circular section of uniform thickness appended to the truncated side of said conical section. The circular structure is supported on a shaft which shaft is supported by two-support members which are connected to a base plate which may be attached to a handle. This construction allows the worker to grasp the handle and utilizing said circular structure which is free to rotate on said shaft such that the leading edge of said central circular section can be utilized to force filler material to the proper depth in a crevice.

Abstract: A hand-operated apparatus for applying a gasketing composition on a part comprising the improvement where there are template means, with a track means beneath the base on which the part is located in which in the track means there moves a roller means which is connected to a movable arm means to which said movable means there is also connected dispensing mean for dispensing the gasketing composition. With such means, the amount of composition that is applied to the part to form a gasket as well as the path of the travel of the dispensing means as well as the height of the dispensing means from the part so as to determine the thickness of the gasket is fixed by the machine, the operator only guiding the starting, the stopping, and the dispensing of the composition.
