MOTOR.

SPECIFICATION forming part of Letters Patent No. 615,844, dated December 13, 1898.

Application filed December 23, 1897. Serial No. 663,206. (N0 DlOdGL) To all whom it may concern:

Beit known that we, JAMES ANDREW GOOD- NER, residing at Mosca, in the county of Costilla, and JAMES M. CHRITTON, residing at Pueblo, in the county of Pueblo, State of Colorado, citizens of the United States, have invented a new and useful Motor, of which the following is a specication.

Our invention relates to motors, and particularly to Water-motors; and the object in view is to provide a simple, compact, and efficient construction and arrangement of parts adapting the device for use as a fluid-pressure motor, a pump, and also a liquid-meter.

Further objects and advantages of this invention will appear in the following description,and the novel features thereof will be par? ticularly pointed out in the appended claims. In the drawings, Figure 1 is a perspective view of a motor constructed in accordance With our invention. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a horizontal section on the line 3 3 of Fig. 2.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings. p In the construction illustrated the casing 1 is arranged in a horizontal position, although it will be understood that the same may be arranged in any other preferred position to suit the particular function to be performed or the direction in which the motive liquid approaches the same, said casing being closed at opposite sides by heads 2 and 3, provided with opposite alined bearings 4i and 5 for the piston-shaft (l and rolling-abutment spindle 7, respectively. The piston-drum 8 is hollow or tubular, and in alinement therewith the casing is provided with a cylindrical eXtension 9, preferably integral with the head 2 and forming a receiving-chamber for the motive liquid, the inlet or supply pipe 10 communicating directlytherewith. Furthermore, the casing is provided with a central web 11, forming a partition abutting at its inner edge against the surface of the drum 8 and dividing the annular space surrounding said drum or between the same and the annular wall of the casing to form independent piston-chambers in which operate the wings or moving abutlnents 12. The drum is open-ended, and within it and preferably formed integral therewith is arranged a feed-spider having spirallydisposed wings 13, which are connected with the drum in the plane of the Web 11jand combined, contiguous to the axis of rotation, to form a hub 14, which is secured to the shaft 6.

The drum is provided in the plane of each annular piston-chamber and respectively in rear of the piston-Wings 12 with inlet-ports 15, through which the motive liquid passes from .the interior of the drum to .the annular piston-chambers when said ports, which are arranged in diametrically opposite positions, are not closed by the segmental cut-off plates or gates 16, which project inwardly or toward each other, respectively, from the heads 2 and 3, with their outer surfaces in contact with the inner surface of the drum, said cut-off plates or gates being at their inner edges contiguous to opposite sides of the wings 13 at their pointsof connection with the drum.

Communicating with the annular pistonchambers is a common outlet or exhaust port 17, and coperatingwith the piston is a rolling fixed abutment 18, consisting of a hollow cylindrical shell provided in the plane of each piston-chamber with a seat 19, through which the piston-wing which operates in said piston-chamber is adapted to pass. Simultaneous rotation of the piston and abutment is secured by means of intermeshing gears 20 and 21, carried, respectively, by the piston and abutment shafts 6 and 7. l The piston drum and rolling abutment are provided contiguous to their ends with suitable packingrings 22 and 23, and arranged longitudinally of the rolling abutment in a suitable seat in the casing is a yieldingly-actuated packingstrip 24, one or more or these packing-strips being used, as may be preferred; also motion may be conveyed from the main or piston shaft 6 to any machinery to be driven through a belt-wheel 25 or other suitable form of gearing.

From the above description it will be seen that the motive agent, whether of Water or other liquid or liuid, is admitted toa receiving-chamber, and thence passes axially into the rotating piston-drum and escapes therefrom radially into the piston-chambers to operate between the piston-wings and the surface of the rolling abutment, the passage of the motive liquid through the drum being unimpeded by the presence of the wings located therein, but, on the other hand, having a tendency to advance the piston in the direction of its rotation by reason of the spiral disposition of said wings. It will be understood, furthermore, that the construction described is adapted without change for use as a pump, and that with suitable packing it is adapted for use as a blower, and that by reason of the simplicity of construction the saine is adapted as a continuous meter, suitable means known in the art being adopted for registering the number of revolutions.

Various changes in the form, proportion, and the minor details of construction may be 'resorted to without departing from the spirit feed-Wings disposed spirally Within the piston-drum, means for feeding the drum with motive fluid at one end, and a rolling abutment operatively connected with the piston, substantially as speciiied.

2. Amotorhavin g a casing, a rotary winged piston mounted in the casing and having a hollow open-ended drum provided with radial feed-ports located contiguous to the wings, feed-wings disposed spirally within the piston-drum and forming the connectionbetween the same and the piston-shaft, a rolling abutment operatively connected with the piston, and a casing extension, forming a receivingchamber, arranged axially of the piston and communicating with the drum thereof, substantially as specified.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of witnesses.
