Application filed. November 6, 1908. Serial No. 461,409.
To all'who'm it may concern:
Be it known that I, PHILIP JAoKsoN DAB- LINGTON, a citizen of the United States, 're siding at New Britain, in the county of Hartford and State of, Connecticut, have invented certain new and useful Improvements in Rotary Motors, of which the followingis a spgcification, reference being had therein to t accompanying drawing.
- This invention relates to motors, and more particularly to motors arranged to be passed through boiler tubes and the like for the purprose of driving tools to remove scale there-' om, although it may be used for other purposes.
The particular object of the invention is to provide a motor which is capable of operation y steam or compressed air, which is powerful, compact, simple and chea of construction, efficient, durable and easi y repaired.
With these and other objects in view the invention consists in the novel construction, arrangement and combination of parts as hereinafter described and claimed. In the accom anying drawings :Figure 1 is a longitudina section through a motor embodying my invention. Fig. 2 is a transverse section on line 2-2 of Fig. 1. -Fi 3 is a longitudinal section taken at right ang es to the section of Fig. 1 and with the piston and socket-ring removed. Fig. 4 is a view looking at the rear end of the motor with the socket-ring removed. Fig. 5 is alongitudinal section on the line 5-5 of Fig. 2, and with piston, bushes, and socket-ring removed. Fig. 6 is a transverse section on the line 6-6 of'Fig. 5. Fig. 7 is a longitudinal section of a modified construction. Fig. 8 is a transverse section on line 8-8 of Fig. 7. Figs. 9, 10 and 11. are longitudinal sectional views showing modified constructions for use in cleaning bent-tubes.
Inthe drawings, 1 represents a cylinder,'2 is a front head, 3 is a rear head, 4 is asocketring, and 5 is a fluid supply ipe. 1, 2, 3 and Sure-all formed with smoot a exterior of circular outline of transverse section at all points, all externally concentric with each other "and joined together with fluid tight transverse joints. Cylinder 1 and head 2 are apart and on opposite si formed with eccentric cylinder bores 6 and 7 respectively. A rotary longitudinal slotted piston 8, with reduced front and rear journal portions 9 and 10 respectively, is su ported concentrically with the exterior of cylinder 1 and contacts along a. line with the curved walls of cylinder bores 6 and 7. Cylinder 1 has an admission longitudinal port 11 formed in its wall and extending from its front to its rear face, andan admission radial port 12 formed in its front face and communicating from port 11 to bore 6. Front head 2 has an exhaust longitudinalport 13 formed in its wall from its rear to its front face and an exhaust radial port 14 formed in its rear face and communlcating from port 13 to bore 7. Admission radial port 12 and exhaust radial port 14 commumcate with bores 6 and 7 respectively at angular ositions about 90 es of the line of co n tact of said bores with piston 8. A blade 15 is loosely carried by and slides in the slot'of piston 8 as it revo ves. The blade 15 contacts in all positions, at both sides and both edges with bores 6 and 7.
26 is a front bush seated in head 2 and r0- tatably supporting piston 8 by journal'portion 9.
27 is an annular balance pocket formed in the rear face of bush 26 under the shoulder of piston 8. v I
28 is a passage communicating from admission ort 11 to pocket 27 to admit lubricant ans fluid under pressure thereto for lubricating and balancing respectively the piston 8 and its forward thrust.
29 is a rear bush seated in head 3 and rotatably supporting piston 8 by journal portion 10.
30 is an annular oil distributing passage around and adjacent to journal portion 10.
31 is a radial oil hole leading to passage 30 from an annular oil distributing passage 32 formed partly in the outer cylindrical surface of bush 29 and partly in the inner cylindrical surface of the seat for bush-29 in head 3.
33 is an oil passage communicating to passage 32 from exhaust port 13 forming With passages 30, 31 and 32 a continuous passage throu h which oil poured in exhaust port 13 will flow to 'ournal ortion 10 when the motor is held front en up.
34 is a shoe ring of external diameter slightly less than the bore of the tube to be cleaned, fitted over the front end of head 2.
to an external shoulder on head 2 and is formed with an internal flange 35 forming an internal shoulder 36.
37 are long screws with heads overhanging andbearing u on shoulder 36, dpassing through head 2, cy inder 1 and threa ed into head 3.
38 is a central hub in pipe '5 with a part spherical socket concentric with the part spherical end thereof and carried on ribs 39. '40 is 2. art s herical headed screw bearing in the soc et 0 hub 38 and forming universal joint therewith. 42 is a hub formed concentric on head 3 threaded to adjustably receive screw-40.
41 is a lock-nut to secure screw 40 as adjusted to hold pipe 5 freely but snuglyinto the socket of rlng 4. in all angular positions of ipe 5.
' he operation is as follows :Flu1d under pressure enters from a sup ly hose through ipe 5, enters the c linder ores 6 and 7, behind blade 15 revo ving piston8 and escaping b exhaust port 13. A suitable tool is attac ed to the front end of piston 8. The motor and tool are advanced through the tube on the end of a flexible su ply hose removing scale from in front of ring 34. The fluid pressure maintains contact between socket-ring 4 and supply pipe 5 which swivels in socket surface 24 to adjust itself to bends in the tube being cleaned. Strainer -st(p the motor.
