Title: Improvements in hydraulic shock absorbers
IPC: F16F9/14
Filed: 1929-12-05
Abstract: 342,832. Hydraulic shock-absorbers. MITCHELL, C. N., 1822, Park Row Building, New York, U.S.A. Dec. 5, 1929, No. 37328. [Class 108 (iii).] An hydraulic shock-absorber for motor vehicle suspensions &c. comprises a cylindrical casing 1, Figs. 1 and 2, containing a rotary shaft 6 provided with a radial piston 7 keyed to the shaft and separating two working compartments A, B, which communicate with an auxiliary supply reservoir 18 through ball-valve controlled openings 13, 12 in radial abutments 11, 10 contacting at their inner ends with the shaft. The casing 1 may be formed of metal stampings, and is provided with keys 10a, 11a to secure the abutments 10, 11 in place. The piston 7 is secured to the shaft 6 by a key 8 in such a manner that the piston has a limited radial movement so as to adjust itself to variations in the wall of the casing. A passage 46 through the shaft 6 permits an unrestricted flow of liquid from the chamber A to the chamber B for small movements of the shaft, and on further movement, the passage 46 is closed by the abutment 11, and a restricted flow takes place through a passage 42 provided with a ball check valve. Further movement causes the abutment 11 to close the passage 42, when the liquid can only flow past the two ends of the piston, thus affording the maximum resistance, which is also operative throughout the rebound movement, on account of the closing of the crank valve in the passage 42. The reservoir 18 is provided with a vent opening closed by a spring-pressed valve 19. The cover structure in capable of flexing outwards under excess pressure, and comprises a cover plate 21 and cover 22 held in place by a thrust ring 25 screwing into a ring 26, which is non-rotatably mounted on a flange 2 on the casing 1. In order to enable the resistance of the shock-absorber to be adjusted, the cover 22 is adjustably flexed inwards by means of a cap 28 screwing through the thrust ring 25 and having tool-receiving openings 29. The cover 22 is provided with a packing-ring 30 engaged by a spring- pressed packing-cup 31. The shaft 6 is provided with filling-passages 39, 40.

Patent GB-1063998-A (GB)
Title: Improvements in building motions for ring spinning and twisting frames
IPC: D01H1/36
Filed: 1963-09-24
Abstract: 1,063,998. Builder motions. HAMEL G.m.b.H. Sept. 24, 1963 [Sept. 27, 1962], No. 37450/63. Heading DID. In a building motion for a ring-frame in which the ring-rail is traversed, through a chain attached at one end to the rail, by the oscillation of a lever engaging a rotating cam and pivoted at one end remote from the cam, two pulleys and a second pivoted lever are provided; one pulley is arranged on the camlever near its end which engages the cam, the chain passes around the two pulleys as it passes from the rail, while the second lever is oscillated more slowly than the cam lever, the arrangement of the parts being such as to allow the position of the reversal points of the traverse to be controlled to produce either single or double taper packages. The cam lever 4 is pivoted at 5 and carries a pulley 6 on an arm 41 near the end which engages the cam 2. The second lever 8 is pivoted at 9 and is arranged to be oscillated by a worm and sector drive driven by a reversible motor 12, the driving- direction of which is reversed as the lever 8 engages contacts 14, 15. When single taper packages are to be produced, the second pulley 17 is arranged at the free end of the second lever, and one end of the chain is attached at 4<SP>11</SP> on the arm 4. The chain then passing around the lower pulley 17, back to the pulley 6 and then to the ring rail. The rotational axis of pulley 6 and the pivot 9 are arranged to be equidistant from the pivot 5, so that when the cam-lever engages the "low" point of the cam and is at the extreme left of its travel the rotational axis of the pulley 6 coincides with the pivot 9. Accordingly, with the two levers oscillating at different rates, whenever the low point of the traverse is reached, whatever the position of lever 8, the pulleys are separated by the same distance. The effective length of the chain is thus the same at the conclusion of each stroke and the ring-rail descends to the same level. It is arranged that the lowest position of the upper return point of the stroke occurs when the lever 8 actuates the switch 15 and the cam lever simultaneously engages the "high" point of the cam; thereafter, as the lever engages the "high" point, the lever 8 assumes different positions to the left of pivot 5 and the distance between the two pulleys increases, and hence, the effective length of the chain decreases. Accordingly the position of the upper reversal point changes from a minimum to a maximum; when the second reversal switch 14 is actuated and the lever 8 moves to the right, the position of the reversal point decreases to a minimum. To produce double taper packages where the position of both the upper and lower reversal points change between maxima and minima the anchorage of the chain is transferred to the lower end of the second lever 8 (Fig. 4 not shown), the pulley 17 is transferred to the lower end of the cam lever, and the reversal switches (14, 15) are displaced to the left.
