Tool device
First Claim
1. A tool device comprising:
- (a) a body defining a bore having a first barrier wall end and second open end;
(b) a tool holder and motor assembly joined to said body and extending into said bore, said assembly including (i) means for joining a tool to said assembly, said tool joining means extending out of said open end of said bore, (ii) elongated rotary motor means having first and second ends, said motor means joined to said tool joining means for rotating said tool joining means, said motor means further having a plurality of radially disposed movable vane members, and (iii) first and second end plates disposed on said motor means at each end thereof, said first end plate located adjacent said barrier wall end of said bore and having inlet openings for directing a fluid into said motor means and said second end plate located adjacent said open end of said bore and having outlet openings for directing fluid out of said motor means and toward said open end of said bore;
(c) means in said body for directing a fluid to said motor means adjacent said barrier wall and through said first end plate; and
(d) means a ring member circumferentially disposed about said tool joining means and securing said assembly in said body, said ring member joined to said body adjacent said open end of said bore and having a plurality of openings in flow communication with and adjacent to said outlet openings on said second end plate,whereby fluid is directed from said barrier wall end of said bore, through said motor means, and out said open end of said bore.

Abstract
This invention relates to a tool device. In the first embodiment, the device comprises a body defining a grip-like, handle, a tool holder joined to the body, a piston and valve assembly disposed in the body adjacent one end thereof, a conduit extending from the valve, a piston slideably disposed on the conduit, as well as means for supplying the device with a fluid under pressure. By the use of the first embodiment of the present invention, the piston is caused to reciprocate in the body thereby producing a hammer-like action. In the second embodiment of the invention, a similar tool handle is used in combination with a tool holder and motor assembly. The assembly includes means for selectively joining a tool to the assembly, and a rotary motor means having a plurality of radially disposed movable vane members, as well as means for introducing and removing a fluid from the motor. By the use of the second embodiment of the present invention, rotary action such as that associated with a rotary sander can be achieved.
