TOOL-MOTOR.

SPECIFICATION forming part of Letters Patent No. 765,100, dated July 12, 1904. Application tiled October 12, 1903. Serial No. 176.717. (No model.)

To all whom it 71u17/ cm1/cern:

Be itknown that I, WILLIAM H. Rons, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Tool-Motors, of which the following 1s a specification, reference being had therein to the accompanying drawings.

This invention relates to a tool-motor, and particularly to a portable device adapted to operate a rotatable tool-holder by compressed air, steam. or other suitable motive agent.

The invention has for an object to provide a casing containing a motor and rotatable toolholder geared to said motor to be driven thereby through the medium of the motive agent introduced into the casing through suitable conducting-pipes.

A further object of the invention is to provide an im proved form of gearing to properly convey the power from the motor or engine to the tool-holder and adapted to eect the proper reduction of speed and increase of power in the movement of the parts.

A further object of the invention is to provide an improved form of oscillating motor adapted to coperate with inlet and exhaust chambers in the casing and mounted with ports adapted to coperate with said chambers in` the oscillation of the cylinder of the motor.

Other and further objects and advantages of the invention will be hereinafter set forth, and the novel features thereof defined by the appended claims.

-In the drawings, Figure l is a central longitudinal section through the invention. Fig. 2 is a section on the line 2 2 of Fig. l. Fig. 3 is a section on the line 3 3 of Fig. l. Fig. A is a section on the line A 4 of Fig. 1, showing the cylinders by dotted lines.. Fig. 5 is a central cross-section at a right angle to Fig. l, and Fig. 6 is a side elevation of the casing.

Like1 letters of reference refer to like parts in the several figures of the drawings.

The letter A designates the casing, which may be of any desired construction, but is preferably formed, as herein shown, with an outer chamber A at one side thereof divided by a transverse partition A2 to form an inner chamber A3 at the opposite side of the partition. (See Fig. 4.) These chambers are separated from the remainder of the casing by a partition-plate A2, through which ports or apertures A5 extend from the outer chamber and A0 from the inner chamber. The air, steam, or other motive agent used is introduced through either of the connections A7 or AS, while the exhaust escapes from the opposite connection. Proper pipe connections may be made at these points by any desired meansH for instance, as herein shown, a feed-pipe B may be used having a handhold B pivoted thereon-this pipe being connected by a threaded socket AJ intermediate of the connections A7 and AS and provided with an inlet-port B2 and exhaust-port B2, adapted to be turned upon the feed-pipe B as a pivot and thus register with either of the connections A7 or AS. The feed-pipe is provided with a discharge-port Bi lat its inner end, while the handhold B/ is provided at its outer end with a socket containing a spring B5, bearing against a shoulder -B on the inlet-pipe and adapted to hold the ports B2 and B3 in contact with the casing. At the opposite sides of the casing from the inletpipe a suitable handle B7 may be provided and secured by threading it into a lug BS.

The partition A2, Fig. 4, is provided with a series of bearings B, disposed at proper points and extending through the partition A2 to support the cylinders C', disposed between the partition AA1 and the partition E. These cylinders are provided intermediate of their ends with a journal or pivot-pin C2, disposed at one end in the bearing C and at its opposite end in a similar bearing C3, carried by the partition E, thus mounting the cylinders of the motors for oscillation. The opposite ends of each of these cylinders are provided with a bearing-face C, adapted to travel in contact with the face of the partition A* and provided with a port C to alternately register with the ports A5 and A6 upon opposite sides of the partition A2 in the oscillation of the cylinder, so that the lpiston (l6 within the cylinder will be thus alternately driven by direct pressure in opposite directions. These pistons are provided with any ordinary construction of piston-rods C', operative-ly con- TOO `nected to the crank-arm C8, secured upon the shaft or bearing-point D, said arm being provided with a counterbalance -weight C, as usual in this art. The shafts or bearing-points D are suitably mounted at one end in bearingboxes D, carried in the partition A", and at their opposite ends in similar boxes D2, carried by the partition E, one end of said shafts being provided beyond the partition with a driving-pinion D3.

Any preferred form of tool-holder may be used in connection with this invention; but as illustrating adesirable construction thereof a tubular holder E' is herein shown adapted to fit within the sleeve or collar E2, forming part of the casing and which is supported and braced by the partition E, surrounding the same, and which partition separates the motors from the driving-gear for the tool-hold er. This holder is provided at its outer end with any character of tool-for instance, cuttingdies E, as shown, which may be supported within the carrying-frame E4. This frame is also provided with an annular portion E, extending within the casing and there provided with a drivinggear or rack-teeth F, while the portion is retained in position by means of an annular plate E, suitably secured to the face of the casing. At the opposite ends of the sleeve or collar E2 bearinc` seats or faces' E7 are provided, upon which bearing-balls E8 are located and adapted at one end to contact with a cone E, carried by the tubular toolholder, and at the opposite end withan adjustable cone E10, threaded upon the free end of the holder and adapted to be secured in its adjusted position by a lock-nut Eu, thus providing' a ball-bearing for the rotation of the holder to prevent friction thereof.

For the purpose of communicating power from the motor to the tool-holder any desired construction of gearing may be provided, and a preferable form thereof is herein illustrated, which comprises a pinion F', mounted upon `a rotatable sleeve F2, which is fitted to the exterior of the casing' sleeve or collar E2 and moves freely thereon. The pinion F is keyed to the lower portion of this rotatable sleeve, while the upper portion thereof is provided with gear-teeth F2, adapted to mesh with a gear Ff, which is mounted in the annular frame FG to rotate therein. Secured to the gear Fi, or to the shaft thereof, is a pinion F5, meshing with the rack-teeth F, carried by the tool-holder. By reference to Fig. 3 it will be seen that the series of gears D", F", and F are provided one for each of the motors and suitably disposed at an angle to each other.

In the operation of the invention the air, steam, or other motive agent entering one of the chambers A or A" passes through the ports therein into each of the motor-cylinders, thereby actuating the piston thereof, which in the movement of the crank-shaft oscillates the cylinder upon its pivot, so as to bring the inlet-port at the previously-charged end 0pposite the exhaust-chamber and the former exhaust-port into communication with the pressure-chamber. The structure whereby a single port at each end of the cylinder coperates with the ports for each of the chambers permits this automatic reversal of the inlet and exhaust to the cylinders without the use of any further valve mechanism, as the throw of the crank-shaft oscillates the cylinder sufficiently for this purpose. The power derived from the shaft of each of the cylinders is transmitted through the gear carried thereby to the gear and pinion carried upon the rotatable collar or sleeve mounted on the fixed portion of the casing, and from this the power is again transmitted to the series of gears meshing with the rotatable collar and through the pinions carried thereby to the annular rack or gear secured to the inner face of the tool-holder, which is thus rotatable in either direction. Vhen it is desired to change the direction of movement, it is only necessary to reverse the inlet and exhaust ports of the handheld, which can be accomplished by rotating the same upon its pivotal support.

It will thus be seen that the devices necessary for producing a tool-motor adapted to rotate any character of tool may all be contained within a casing of comparatively small size and adapted for operation by any desired motive agent, while the power being applied from a series of points at an angle to each other secures a smooth and even rotation of the holder, which cannot be secured in the application of the power at a single point.

It will be obvious that the character of the motor, the gear used therewith, and the toolholder driven thereby may be altered, as well as other changes made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.
