Title: Improved seal assembling device
IPC: B25B27/00
Filed: 1967-02-16
Abstract: 1,118,276. Seals. CROSS CO. 16 Feb., 1967 [17 Feb., 1966], No. 7418/67. Heading F2B. In a device for assembling annular seals in a housing opening, e.g. oil seals 55 in an opening in a vehicle differential housing 19, and comprising reciprocatable tool means for pressing the seal in the opening, in order to ensure lubrication of the seal during its initial period of use the tool means includes port means through which lubricant is supplied to the inner surface of the seal when the latter is pressed in the opening. A differential housing 19 is supported on a pallet 17 controllably movable along a table 15 to position the housing at its work station beneath a pressing and lubricating apparatus 21 which is secured to a frame 13 and comprises a platen 107 secured to the piston rod 109 of an hydraulic motor 111. A tool body 117 fixed to the platen 107 has a nosepiece 123 with a reduced end 127 to fit slidably within an oil seal 65 for a pinion collar (not shown) to be secured to the housing spindle 29. An oil seal delivery device comprises a cross slide 35, Fig. 2, slidably supported in a channel 33 and coupled to the rod 47 of an hydraulic motor 43. An escapement fixture 53 including a spring-loaded finger 63 is secured to the slide 35 and engages an oil seal 55 supplied from a feeder track 57. Reversal of the motor 43 is controlled by limit switches 89 and 91. When the slide is moved to the position indicated by dot-dash lines in Fig. 2 the platen 107 is moved downwards by the motor 111, the nosepiece reduced end 127 enters the seal until the face 129, Fig. 3, engages the seal which is then freed from the fixture 53 by further downward movement of the nosepiece and is finally pressed into a seat 131 in the housing 19. Alignment between the nosepiece 123 and the seat 131 is ensured by engagement of a conical end 135 of a spring-loaded pin 133 slidable in the body 117 with a conical seat 137 in the end of the spindle 29. After it is pressed into the seat 131, the seal is lubricated by a measured quantity of grease supplied from a grease supply and pump 155 connected by a conduit 157, metering valve 159 and flexible conduit 161 to an inlet 165 leading via passages 167, 169, 171 and 175 in the body and nosepiece to a grease pocket 173 in the inner surface of the seal. The metering valve 159 is controlled in timed relation to the movement of the platen 107. The nosepiece may have a face 195 to engage the inner race 199 of the bearing 151 whereby downward movement of the nosepiece both seats the seal 55 and press fits the race 199 on the spindle.

Title: Vehicle seat belt retracotr mechanism
IPC: B60R22/40
Filed: 1975-02-21
Abstract: 1453582 Inertia reels for seat belts FORD MOTOR CO Ltd 21 Feb 1975 [14 March 1974] 7452/75 Heading A3V A vehicle seat belt retractor mechanism has a belt-receiving reel 11 mounted on a shaft 12 journalled in side walls 13 of a support bracket 14. Circular plates 15 at each reel end carry peripheral ratchet teeth 16. A locking bar 17 is pivotally mounted in walls 13 parallel to shaft 12 and is driven by an inertia sensor comprising a pendulum 22 into engagement with plates 15 to lock reel 11 against rotation in a belt protraction direction. A substantially vertical, elongate drive link 29 parallel to wall 13 has, at one end, a first portion 31 abutting pendulum 22 and a second portion 35 having an interlocking connection with bar 17 and, at the other end, a pawl 37. An annulus 40 having internal ratchet teeth 42 is secured to plate 15. Acceleration of pendulum 22 raises link 29 so pawl 37 engages internal teeth 42 but the interlocking connection has a lost motion segment so that bar 17 is non-responsive to the initial movement of the link. Rotation of the reel in a belt protraction direction causes annulus 40 to further raise link 29 to drive bar 17 into engagement with plate 15 to lock reel 11 against further movement in this direction. As shown, bracket 14 is mounted on an inclined roof rail so pendulum 22 hangs vertically. Teeth 42 are positioned in a predetermined relationship to teeth 16, bar 17 being driven to engage teeth 16 in sequence to engagement of pawl 37 with teeth 42. Pendulum 22 and link 29 are externally of wall 13 and pawl 37 extends through a slot in the wall towards annulus 40. Portions 31, 35 are laterally offset from each other and are both at the lower end of link 29, pawl 37 being at the upper end. Annulus 40 is secured to plate 15 and is between the latter and wall 13. Bar 17 is non-responsive to initial movement of link 29 because stem 34 of the link moves between a bifurcated extension of bar 17 until portion 35 engages the extension, thus stem 34 constitutes the lost motion segment.

Abstract: 374,516. Cleaning metals. POWELL, R., 31, Penallt Terrace, and THOMAS & CLEMENT, Ltd., Morfa Engineering Works, both in Llanelly. March 13, 1931, No. 7709. [Class 82 (ii).] In a machine for branning tinplates or for dusting and polishing tinplates and the like after branning, two or more co-operating pairs of cleaning rolls are provided, each of which is arranged at an angle other than a right-angle to the direction of movement of the plates through the machine and which preferably rotate in a direction opposite to the direction of travel of the plates. In a dusting and polishing machine three pairs 14, 17, 6 of sheepskin covered cleaning rolls are provided, the pairs 14, 17 rotating in a direction opposite to the direction of travel of the plates and being journalled on shafts 12, 15 respectively, disposed at an angle of approximately 45‹ to the side frames 1, 2 of the machine. The rolls 17 are longer than the rolls 14 and overlap them at the inner end. The plates travel in the direction shown by the arrow A and are passed by rubber-covered conveying rolls 25, 26, 18, 21 through the cleaning rolls 14, 17 to another pair of conveying rolls 10, disposed within the angle formed by the cleaning rolls 14, 17, which directs them past a sponge rubber wiper 9 to parallel spaced guide-bars 8 which lead to the third pair of cleaning rolls 6 which are disposed at right-angles to the framework and rotate in the direction of travel of the plates. The plates are discharged from the machine by rubber-covered conveying rolls 4, 5. The rolls 6 rotate at a greater speed than the conveying rolls and the rolls 14, 17 at approximately the same speed as the conveying rolls. The invention is also applicable to machines for scrubbing or scouring black plate or strip metal in which angularly disposed brush rollers or cotton disc rollers are used, preferably in conjunction with a water spray.

Drawings to Specification. [Class 39 (i)] Discharge lamps having a main filling of rare gas such as neon, and an auxiliary gas or vapour serving to facilitate starting, but not taking part in the steady light emission, such as xenon, krypton, argon or mercury, contain an absorbent substance laden with the auxiliary gas or vapour, which is slowly liberated during periods of rest. The auxiliary filling is cleaned up during the first few, seconds of starting and the rate, of liberation from the absorbent substance is kept lower than the rate of clean up, so that there is no appreciable atmosphere of auxiliary filling during operation. Suitable substances are activated carbon, alumina, silica gel or an amalgam formed by fusing 10 per cent of zinc or tin with mercury. The substance may be placed in the exhaust tube, in a perforated glass ball within the tube, or even on a cool part of an electrode. Carbon containing xenon may be contained in a side tube communicating with the main tube through a narrow opening made by breaking a fine point, by a steel ball or by high-frequency heating, after sealing.
