Title: Improvements in or relating to Rotary Regenerative Preheaters for Combustion Air
Inventor: THOMSON JAMES EDGAR
IPC: F28D19/04
Filed: 1966-03-22
Abstract: 1,153,321. Thermal regenerators. JAMES HOWDEN & CO. Ltd. 19 Dec., 1966 [22 March, 1966], No. 12467/66. Heading F4K. A rotary regenerator air preheater incorporating a thermally actuated expansion compensating device comprises an open ended drum 2 including a series of radial division walls 6, each wall 6 being divided near its upper edge by a radial slot 9 and a vertical slot 12 into a sealing tongue 16 and a lower portion 11 which are interconnected by strut members 13. The invention is intended to minimize leakage through the seals at the hot end of the drum due to distortion, the arrangement being such that due to the compensating strut members the sealing tongues remain substantially unaffected by distortion of the main part of the drum. Each strut member 13 comprises a horizontal bar 15 pivotally attached to a sloping bar 14 slidably held by guides 19 thus allowing any axial or radial distortion of the drum to be compensated during operation. Expansible baffle seals (10, Fig. 3) connect the sealing tongues 16 with the lower portions 11, and sector walls 7 interconnect the radial wall portions 11 forming therewith compartments 8 within which are housed units of pervious regenerative heat transfer material. Other sector walls 18 interconnect adjacent sealing tongues 16 enabling the number of strut members required to be kept to a minimum. The invention is said to be applicable also to regenerative preheaters with rotatable inlet and outlet ducting and a static carrier drum.

Filed: 1923-05-10
Abstract: 220,070. Streader, R., and Horsman, T. O. May 10, 1923. Driving arrangements for paddlewheels.-In a power unit and transmission mechanism for driving and steering paddle steamers the engine shaft 2, Figs. 1 and 2, drives a parallel counter-shaft 22 through forward and reversing spur and chain gearing 3, 21, the paddle wheels 6 being driven through gearing and steering clutches 7 provided on the ends of the countershaft. The clutches 7 are operated by a steering wheel 13 acting through a cam 26 and rods 25. so that rotation of the steering wheel in either direction releases the corresponding clutch and the vessel turns to one side. Continued movement of the steering-wheel applies a brake on the declutched side, through an arm 26<c>, links 27<a> 27, a stop 29, and a cam 28, Fig. 6. If the brakes are already applied to both wheels by means of a pedal 15 and connections 30, rotation of the steering-wheel releases the brake on one side by means of the link 27 and the use of the flat part of a cam 31, so that the vessel is steered. The reversing clutches 4 are operated by a pedal 16, and another pedal 14 operates the clutches 10, 11 of an epicyclic two-speed friction gear shown in Fig. 3 The chain and spur wheel 9, driven from the engine, may be directly connected to the shaft 22 by a clutch 11, or may drive the shaft indirectly through planetary friction rollers 24 rotatably carried by a boss 20 slidably-keyed on the shaft. When the clutch member 10 is moved along the shaft it engages the rollers 24 and bring them into contact with a cone on the gear wheel 9 ; at the same time teeth 19 or the clutch engage a stop and hold the clutch stationery, so that the member 20 and the shaft 22 are driven at a reduced speed. The lower part 37 of the steering shaft carries two other cams for acting upon the steering clutches in addition to the cam 26; with one of these both clutches may be held out of engagement, while the engine drives other machinery by means of a pulley 36; with the other cam both clutches may be disengaged or one at a time may be engaged. The steering shaft 13 fits removably into the top part of the shaft 37 or into a parallel stub shaft geared thereto, for use when driving continuously in the reverse direction. The hand-wheel and shaft 13 mav be replaced by a lever fitting over the shaft 37.

Title: Pouncing machine
IPC: A42C1/08
Filed: 1939-05-05
Abstract: 528,406. Hat pouncing machines. DORAN BROS., Inc. May 5, 1939, No. 13532. Convention date, Aug. 24, 1938. [Class 63] Relates to machines of the kind described in Specifications 462,413 and 484,344, wherein the pouncing pad is driven in a substantially elliptical path and the hat and pad are relatively traversed so that the whole of the crown is operated on, and consists in mounting the tool so that it can swivel freely on a vertical axis to allow it correctly to follow the hat surface. To lessen vibration the reciprocating and swinging mechanism of the pad drive is balanced. An alternative work support allows conical hat bats to be treated, the bats being held to the support by air jets or suction. As described in the prior Specifications, the tool is traversed over the crown by movement about an axis 33, a bracket 34 swinging about this axis supporting a horizontal shaft 38 on which is pivoted a plate 39 slotted adjustably to support a member 44 housing ball bearings carrying the tubular extension of a plate 53 slotted to carry adjustably a plate 61 supporting the pouncing tool. As heretofore, the pad support is swung about the axis 38 to remove the tool from the work at the end of the operation. The limit to which the support can swing towards the work is determined by a handwheel 108 turning with an eccentric contacting an arm 104 bolted to the support. A driven shaft 69 carries an eccentric 74 the strap of which is secured to a shaft 79a reciprocating through guides themselves trunnioned at 82. The shaft 79a carries the pouncing pad, which is thus moved in an elliptical path. To balance this mechanism the shaft 69 carries a pair of eccentrics 72, 73 spaced 180 degrees from the eccentric 74 and actuating slides 89, 90 in guides pivoted at 94, 99. For dealing with conical bats, a feltcovered workholder 130 on a rotating shaft 112 is covered by a fixed hood 133 except for a wide slot at one side, which slot extends over the end of the holder. The bat is placed over the hood, and urged against the rotating holder by air jets from pipes 142, 143 on each side of the pouncing pad. Alternatively, suction is applied to the inside of the hood by a pipe connection 147. As heretofore. the workholder is moved axially by a piston 126.

Title: Improvements in automatic slack-adjusters for railway vehicle brake riggings
Inventor: PERSSON GERT ARTUR
IPC: B61H15/00
Filed: 1967-03-23
Abstract: 1,128,693. Slack adjuster for brake rigging. SVENSKA A.B. BROMSREGULATOR. 23 March, 1967, No. 13606/67. Heading F2E. In an automatic slack adjuster for railway vehicle brake riggings, of the kind comprising a screw-threaded spindle extending through one or more nuts (not shown), the relative axial positions of which are variable in known manner for effecting automatic slack adjustment, the end of the spindle which is normally connected non-rotatably to the brake rigging is provided with a detent device in accordance with either Fig. 3 or Fig. 5, depending upon whether the slack adjuster transmits tension or compression forces, respectively, the device comprising two interengaging toothed members capable of overriding each other only when the brake is released and when sufficient manual force is applied. In the Fig. 3 form, the detent device comprises a sleeve 15, which is coupled to the brake rigging by integral pins 16, 17, the sleeve being slidable on a plain end portion of the screw-threaded spindle 2 and carrying an extension sleeve 18 having an inwardly directed flange 19. A compression spring assembly 20 is arranged between the flange 19 and an outwardly directed flange 8 on the spindle 2 to normally maintain shoulder 21, provided by the flange 8, in contact with the sleeve 15. In this position, relative rotation of the sleeve 15 and spindle 2 is prevented by interengaging teeth on the lefthand face of the flange 19 and on a part 10 which is secured on a threaded end portion of the spindle 2 of reduced diameter by a nut 13. When sufficient manual force is applied to the nut 13, however, the spindle 2 can be rotated, since the teeth on flange 19 and part 10 can then override each other by camming action, compressing the spring assembly 20. In the Fig. 5 form, a sleeve 39 is slidable on a reduced diameter extension of the screw-threaded spindle 33 which, when sufficient manual force is applied to a nut 44, can be rotated to force apart interengaging teeth on the sleeve 39 and on a part 38 secured to the spindle 33, the teeth normally being held in engagement by a spring 45 embedded in rubber 46 and urging the sleeve 39 into engagement with a shoulder 42 of the spindle 33. In both embodiments, the respective shoulders on the screw-threaded spindle prevent full engagement of the interengaging teeth, the tension or compression in the rigging assisting the spring force to prevent disengagement of the teeth during a brake application.
