Title: Improvements in fluid heater cleaning systems and the motors for use therein
Inventor: MCCOLL WILLIAM
IPC: B08B9/043
Filed: 1957-10-14
Abstract: 900,030. Soot-blowers. BABCOCK & WILCOX Ltd. Oct. 14, 1958 [Oct. 14, 1957], No. 32070/57. Class 99(2). In a fluid-heater cleaning system comprising a number of lance-type blowers each having a motor 27 for effecting advance and retraction of the lance 7 and a driving shaft 32 adapted for emergency operation for effecting the retraction of the blower independently of the motor, there is provided a portable, auxiliary motor which has means complementary with each of the blowers whereby the motor may be selectively operatively positioned in relation to any one of the blowers with the output shaft of the motor coupled to the driving shaft of the blower. As shown, each blower, Fig. 1, comprises a telescopic, nozzle tube 7 advanced and retracted on a carriage to and from the operative position, and rotated, by an electric motor 27 and is of substantially the same construction as the soot-blower described in Specification 636,052. The portable, reversible air motor 61, Fig. 6, has a crankshaft 64 geared to a shaft 68 which drives by a duplex chain 70 an output shaft 72 formed with a recess 75. The latter includes a square recess 81 into which fits the squared end portion 50 of the shaft 32. Apertured, laterally-extending lugs 85, Fig. 7, on the boss 74 of the motor casing co-operate with an apertured lug 52 on the casing of the motor 27 and movement of the motor 61 is prevented by insertion of the pin 87 of a member 86 through the lugs; the member includes a tongue 90 adapted to engage within a slot 88 in the shaft 68 so that the square recess 81 and the portion 50 of the shaft 32 can be brought in alignment. In the event of failure of the motor 27 to retract the blower, such retraction is effected by application of the motor 61. Specifications 533,609 and 900,031 also are referred to.

Abstract: 379,153. Kinematograph apparatus. DEBRIE, A. L. V. C., 111, Rue St, Maur, Paris. Nov. 21, 1931, No. 32322. Convention date, Jan. 8. [Class 97 (i).] Variation between the speeds of a sprocket driven by the film, and of the sprocket spindle driven by the mechanism, causes relative movement between members carried by the sprocket and spindle to stop the film drive. As shown, a sprocket 2 rotated by the film has a circular sloping surface 5, within an end recess 4, engaging one end of a spring-pressed pin 9 carried by an arm 8 on a spindle 7 driven by the mechanism; relative rotation of the sprocket and spindle, caused by slowing or stoppage of the film movement, causes the pin 9 to ride up the surface 5 and push a plate 13 into a fixed cylindrical guide 14, so that a stud 15 carried by the plate 13 presses a contact 17 into engagement with a contact 21, and completes the circuit of an electromagnet to open the motor circuit or disconnect the drive from the motor. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a driving connection between the motor and the apparatus. Such connection comprises a motor-driven spindle 25, Fig. 6 (Cancelled), formed with a slotted projection 26 housing a wooden key 28, the projection 26 and key 28 respectively engaging a recess 23, Fig. 5 (Cancelled), and a slot 24 in a spindle of the apparatus. Excessive driving torque causes breakage of the key 28 and cessation of the drive. The key may be held in place by a pivoted cover on the end of the projection 26 and by a sleeve 31 round the spindle 25. This subject-matter does not appear in the Specification as accepted.

Abstract: 194,359. Kent, W .G. Dec. 9, 1921. Valves actuated by rotary motors.-A device for maintaining a constant flow of water, particularly applicable for use in connection with the distributtory canals of irrigation works comprises a gate valve actuated by a turbine, water wheel or other motor, controlled by a valve actuated by mechanism under the control of the pressures at a constriction in the conduit and at a point on the upstream side thereof. The gate valve J which is situated in the down-stream side of the main channel B at a point remote from the constriction D is actuated by a worm and worm wheel J<1>, driven by a turbine K. The turbine is rotated in one direction or the other bv water from the main conduit delivered through a grating L<1>, conduit L and dirt-trap L<2> and controlled by a double-piston valve K<1>. The valve K<1> is actuated by a diaphragm loaded by centring springs O<2> and controlled by a pilot valve N, connected by an adjustable telescopic rod S to a beam G. The beam G, which also actuates a recording apparatus H, is connected to two displacers f, f<1> working in chambers F, F<1> connected by pipes to the main conduit B and the throat respectively. To shut the valve and put the apparatus out of action the rods and a rod Q are operated from a surface box R so as to put the valve N in the closing position and to move a rod P<2> actuated by a tappet in the worm wheel opposite the spindle of a valve M so that as the main valve closes this valve is moved to shut off the supply to the valve N and to connect the two sides of the diaphragm together. A semirotary pump U having a hinged outlet is fitted for emptying the sump V and drawing water through the pipes E, E' to clear them of silt. A pipe X controlled by a cock connects the chambers F, F' whereby the pressures can be equalized when desired. The volume of water flowing is regulated bv varying the length of the rod S, the adjustment being indicated on a scale S<1>.

Abstract: 656,016. Roll-film photographic cameras. KODAK, Ltd. Dec. 22, 1948, No. 33052. Convention date, Dec. 30, 1947. [Class 98 (i)] [Also in Group XXIV] Film-winding mechanism for roll-film cameras includes a winding shaft having a pair of cylindrical surfaces rotatable therewith, and having coaxially mounted thereon a freely rotatable driven element adjacent to one cylindrical surface and a non-rotatable element adjacent to the other cylindrical surface, both elements having a cylindrical surface of the same diameter as the adjacent cylindrical surface on the winding shaft, and a pair of coil springs wound in opposite directions and each embracing a.different pair of adjacent cylindrical surfaces to function as a unidirectional clutch between the rotatable driven element and the winding shaft and as a reverse lock for the winding shaft. As shown, Fig. 3, a sleeve 16 and a pinion 10 are mounted coaxially on a winding shaft 12 having a bearing ring 21 journalled in a fixed plate 35, and a shoulder 19 against which a washer 20 bears. A screw 23 clamps the ring 21, sleeve 16, and washer 20 against the shoulder 19 so that sleeve 16 is fast with shaft 12. Pinion 10 rotates freely on a recessed part of sleeve 16. Pinion and sleeve have contiguous cylindrical surfaces of the same diameter embraced by a spring 18. When the pinion 10 is turned in one direction the coils of spring 18 tighten and transmit motion to sleeve 16 and shaft 12, but when the pinion is turned in the opposite direction the coils open slightly and shaft 12 is not turned. The lower part of shaft 12 is journalled in a member 13 fixed to a plate 26. Member 13 and an enlarged part of shaft 12 have contiguous cylindrical surfaces of the same diameter embraced by a spring 30 coiled in the opposite direction to spring 18, forming a one-way clutch which is inoperative when the shaft is rotated by pinion 10, but which operates to hold the shaft against any tendency to reverse rotation. Shaft 12 terminates in a key 24 engaging a film spool 32. Plate 35, Fig. 1, is spaced from plate 26 by bolts 36, 37. A plate 38, having an external ratchet-toothed sector 42, and an internally toothed sector 41 meshing with pinion 10, may be rocked about bolt 37 by a lever extension 39 against action of a spring 43. This rotates pinion 10 in the direction to turn shaft 12 and wind the film. A ratchet 45, forming part of a mechanism such as that described in Specification 449,769, engages sector 42 to stop the movement when a length of film equal to one frame has been wound through the camera. On return of plate 38 by spring 43, spring 30 engages the cylindrical surfaces of member 13 and shaft 12 to hold the latter against movement. Preferably, spring 30 is covered by a casing 34 on a rim of shaft 12. Spring 18 may have a similar casing.
