Abstract

Abstract Hand-held troweling tool for applying putty to a workpiece, including a handle and a head assembly secured to the handle which has a cavity therein opening to the bottom of the tool. One end of a compressible tube through which putty may be supplied to the cavity opens into the cavity. A movable clamp member adjacent the cavity is yieldably biased against a side of the tube to compress it to stem the flow of putty therethrough to the cavity. A trigger lever on the handle is operable to remove the biasing force to permit putty flow. A strike off plate in the head assembly adjacent the cavity produces a desired surface contour to putty dispensed through the cavity onto a workpiece.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 208 words
A hand-operated troweling tool for applying putty and like flowable material to a workpiece comprising a head assembly adapted to be slid over the workpiece including at the base thereof a substantially flat guide plate portion and a strike off plate having a lower strike off edge substantially in the plane of said guide plate portion, said guide plate portion and strike off plate between them defining an elongate cavity opening to the bottom of said head assembly which opening substantially parallels said strike off edge, a substantially upright handle secured to said head assembly and projecting upwardly therefrom in a direction away from said guide plate portion by which the tool may be held and through which force may be exerted to press the guide plate portion of the head assembly tightly against a workpiece, a compressible tube communicating with said cavity through which putty may be supplied under pressure to the cavity from a source remote from said base, and control means for controlling the flow of putty through said tube including a movable clamp element adjacent said cavity shiftable to bear against said tube to compress the same and an upright trigger lever extending along a side of the handle for actuating said clamp element.
Claim 2
Dependent Claim 208 words
A hand-operated troweling tool for applying putty and like flowable material to a workpiece comprising a head assembly adapted to be slid over the workpiece including at the base thereof a substantially flat guide plate portion and a strike off plate having a lower strike off edge substantially in the plane of said guide plate portion, said guide plate portion and strike off plate between them defining an elongate cavity opening to the bottom of said head assembly which opening substantially parallels said strike off edge, a substantially upright handle secured to said head assembly and projecting upwardly therefrom in a direction away from said guide plate portion by which the tool may be held and through which force may be exerted to press the guide plate portion of the head assembly tightly against a workpiece, a compressible tube communicating with said cavity through which putty may be supplied under pressure to the cavity from a source remote from said base, and control means for controlling the flow of putty through said tube including a movable clamp element adjacent said cavity shiftable to bear against said tube to compress the same and an upright trigger lever extending along a side of the handle for actuating said clamp element.
Claim 3
Dependent Claim 55 words
The troweling tool of claim 1, wherein said handle is positioned in advance of said head assembly when pulling the tool in a pass over the workpiece, and wherein said tube extends outwardly from said head assembly at the top of the head assembly in a position which trails the handle during such a pass.
