ATTORNEY Patented Jan. 14, 1936 UNITED STATES PATENT OFFICE EXHAUST DEFLECTOR Application March 14, 1934, Serial No. 715,460
5 Claims.
This invention relates broadly to fluid actuated tools, but more particularly to the construction of exhaust deflector therefor.
One object of this invention is to produce a 5 novel simple, and effective device for deflecting the fluid exhausting from a fluid actuated machine away from the operator. Another object of this invention is to provide a fluid actuated machine with a combined exhaust deflecting and exhaust controlling device susceptible of ready manipulation.
These objects are accomplished by a construction free of complication, and by arrangement of parts resulting in a compact unit which is. strong, durable, and efiicient.
In the drawing which illustrates a preferred embodiment of the invention:
Fig. 1 is a longitudinal view partly in section of a fluid actuated tool embodying the invention.
Fig. 2 is an enlarged longitudinal cross sectional view illustrating the exhaust deflector in one position.
Fig. 3 is a view similar to Fig. 2, illustrating the exhaust deflector in another position.
Referring to the drawing in which like symbols designate corresponding parts throughout the several views, I represents the casing or cylinder of a fluid actuated percussive tool having secured thereto a handle II. Within the handle I I, there is incorporated a throttle valve operable by a throttle handle or lever I2. Reciprocably mounted within the cylinder II], there is the usual piston I3 which is responsive to the action of the pressure fluid admitted into the cylinder through passages I4. The admission of the pressure fluid into these passages may be either piston or valve controlled, but since this portion of the mechanism does not constitute a part of the present invention, no further description of the same is thought necessary. Slidably mounted within the front end of the cylinder Ill, there is a tool implement I5 adapted to receive the blows of the piston l3.
Referring now more particularly to the present invention, I6 represents an exhaust port leading from the interior of the cylinder II] to the atmosphere, through which pressure fluid admitted into the former is normally free to exhaust therefrom when the piston reaches the ends of its strokes. Adjacent the exhaust port I6, the external wall of the cylinder is formed with an annular groove II adapted to receive the constricted end coil I8 of a compression spring I9, the latter being of a normal inner diameter somewhat greater than the external diameter of the cylinder I0. The spring I9 is completely surrounded or circumscribed by an exhaust deflecting hood or sleeve 2|]. The ends of the latter are machined to provide internal flanges 2I and 22 forming abutments engaging the end coils of 5 the spring I9 for securing the sleeve 20 to the cylinder in slidable and rotatable relation therewith. Radially disposed through the sleeve 20, there is an orifice 23, of a diameter substantially equal to that of the exhaust port I6.
In assembling the device, the spring I9 is first introduced into the sleeve 20 by screwing theformer over one of the inturned flanges 2| or 22. To cause the opening of the constricted coil I8 when the spring and sleeve are introduced over 15 the cylinder, the front end of .the latter is beveled as at 24. Subsequently, the sleeve and spring are simply pushed upwardly on the cylinder until the coil spring I8 drops into the groove II. When it is desired to remove the deflector 20 from the cylinder, sufficient downward pressure must be applied on the sleeve 20 to cause the constricted coil spring I8 to open and slip out of the groove H.
The constricted coil end spring I8 being of a 25 normal diameter somewhat smaller than that of the groove II, will exert enough clamping action on the cylinder to permit the full compression of the spring in a solid member when sufficient upward pressure is applied to the sleeve 20. In 30 this instance, the spring fully covers the exhaust port I6, thus preventing the exhaust of the pressure fluid from the cylinder I0. The amount of pressure fluid exhausting from the cylinder may also be varied by somewhat releasing the upward 35 pressure applied on the sleeve 20, thus permitting a more or less complete separation of the coils of the spring I9.
The radial angle at which the pressure fluid is exhausting from the cylinder I0 may be varied 40 by simply rotating the sleeve 20, since the fluid escaping through the exhaust port I 6 is admitted into the sleeve and escapes through the port 23 irrespective of the position of the latter with port I6.
Although the foregoing description is necessarily' of a detailed character, in order to completely set forth the invention, it is to be understood that the specific terminology is not intended to be restrictive or confining and it is to 50 be further understood that various rearrangements of parts and modification of structural detail may be resorted to without departing from the scope or spirit of the invention as herein claimed.
I claim: I r
1. In a fluid actuated tool, the combination with a cylinder having an exhaust port, an exhaust controlling device comprising a member secured to said cylinder and movable in exhaust port open or closed position, and an exhaust deflector normally rotatably supported by said member.
2. In a fluid actuated tool, the combination of a casing having an exhaust port, an exhaust controlling member mounted on said casing and movable for opening and closing said exhaust port, and an exhaust deflector mounted on said casing and supported by said controlling memher, said deflector movable on said casing for actuating said member for closing the exhaust port.
3. In a fluid actuated tool, the combination of a casing having an exhaust port, a coil spring secured at its upper end to said casing, and an exhaust deflecting member completely circumscribing said spring and supported thereby in a manner whereby said member is capable of relative rotation with respect to said spring and exhaust port of the casing.
4. In a fluid actuated tool, the combination of a casing having an exhaust port, an exhaust hood formed with an aperture rotatable in variable angular relation with respect to said port, and a coil spring carried by said cylinder circumscribed within said hood for supporting the latter, said spring upon longitudinal movement of said hood being capable oi compression to close said exhaust port.
5. In a fluid actuated tool, the combination with a cylinder having an exhaust port, a coil spring circumscribing said cylinder and formed with a coil smaller thanthe. other coils thereof, an external annular groove on said cylinder adapted to receive said smaller coil in spring supporting relation, and an exhaust deflecting member rotatably supported by said spring.
