Title: Improvements in change-speed gearing for automobiles
IPC: F16D23/04
Filed: 1924-09-30
Abstract: 231,762. Enzesfelder Metallwerke Akt.-Ges. Aug. 1, 1924, [Convention date]. Variable - speed g e a r i n g ; clutches, claw.-Means for facilitating the engagement of clutch teeth in change-speed gearing consist of auxiliary friction clutches w<1>, w<2> combined as a symmetrical unit sliding with and also relatively to a svmmetrical double-ended claw clutch sleeve K. In the arrangement shown, A is the driving-shaft, B a. lay shaft, and C the driven shaft. The clutch sleeve K with dog ends k<2>, k<4> is splined on the shaft C and is adapted to engage dogs k<1> on the shaft A for direct driving, or dogs k<3> on a gear n<1> for a reduced speed. The auxiliary friction cones w<1>, w<2> slide together on the sleeve K, being coupled by a member w. These cones are restrained against axial movement relatively to the sleeve K by ball-ended spring bolts p in the sleeve engaging the cones. On moving the sleeve K to right or left, the cone w' or w<1> comes into contact with a female cone f, and the clutch dogs about to be engaged are brought to nearly the same rotational speed. Further movement of the sleeve K causes the bolts p to slip inwards out of action, releasing the pressure between the cone clutch surfaces. Continued sliding of the eleeve K then brings the dogs k<4> or k<2> into full engagement.

Title: Internal gear machine
IPC: F04C2/10
Filed: 1977-06-03
Abstract: In the internal-gear pump there is arranged between a pinion (15) and a ring gear (16) a semi crescent-shaped filler piece capable of limited free movement. The filler piece (20), together with the gear wheels (15, 16) delimits a discharge chamber (19) and, counter to the revolving direction, by means of a supporting face (23) rests on a filler piece pin (21) fixed in the casing. The ring gear (16) is supported, in the region of the discharge chamber (19) directly in the casing (10) by its external lateral face (17). The spacing (x) between the supporting face (23) of the filler piece (20) and the axis (24) of the filler piece pin (21) is adjustable in order to ensure that the filler piece (20) rests snugly against the tooth tips of the gear wheels (15, 16). So that this pump can be employed in the high-pressure range up to approximately 300 bar, the filler piece (20), which is constructed in one piece, has an internal chamber (30) which extends essentially over the entire length of the filler piece parallel to the rotational axes of the gear wheels (15, 16) through the filler piece. The internal chamber (30) communicates with the discharge chamber (19), and its cross-section is dimensioned in such a way that the filler piece (20) expands elastically under the liquid pressure. <IMAGE>

Filed: 1957-07-29
Abstract: 836,646. Pipe couplings. WEATHERHEAD CO. July 29, 1957 [Aug. 27,1956], No. 24017/57. Class 99(1). In a pipe coupling particularly for conducting liquid or gaseous oxygen, ball detents 18 secured within the wall 17 of a socket A while being allowed to partly extend on one or other side, enter grooves 24 of a plug B wherein they are engaged by a locking sleeve 26 urged by a spring 128 over the grooves 24, an unlocking sleeve 28 engaging the sleeve 26 which it retracts to permit uncoupling. Socket A. A spring loaded valve 10 seats against a synthetic plastic washer 12 made gastight by providing one of the metal surfaces against which it is retained with spaced concentric rings 87 which bite into the washer 12 and may penetrate to the other flat surface 90. The valve 10 is acted upon by a stud 76 of a filter 74. The ball detents 18 are forced through an undersized aperture 92 to an undercut portion in which they can freely float in an axial direction limited by the shoulders of the undercut. An apertured sealing washer 68 provided with an incurved lip 70 is situated between ball detents 18 and filter 74. Plug B. A valve 10<SP>1</SP> and washer 12 are provided as in the socket A, the valve 101 bearing against a hollow insert 110 having a thickened end to provide shoulders 112 limiting movement. The end of the insert bearing against the valve is formed with projections 116 with bevelled ends so that on unseating the valve, ports are formed for fluid flow. A plug portion 23 fitting over the insert 110 is formed with the grooves 24 and the locking sleeve 26 thereon is limited in movement by a stop 136 on the unlocking sleeve 28. Unlocking sleeve 28 is limited in movement by pins 138 engaging sides of a recess 140. A dust cover 142 may be provided. Operation. Socket A and plug B are pushed together, the plug portion 23 entering the wall 17 and causing the ball detents 18 to ride on the outer periphery of the plug portion and move outwards thereby engaging end 125 of the locking sleeve 26. Further coupling movement causes the retraction of locking sleeve 26 against spring 128 until the ball detents 18 are forced to enter grooves 24 and the coupling is locked by sleeve 26 snapping back over the wall 17. During the coupling movement the plug portion 23 enters the washer 68 and the end 118 of the insert 110 presses against the filter 74 thereby unseating the valve 10. The movement of the filter is limited by a wall 60 so that the end 108 of the plug portion 23 is moved up to coincide with the end 118 thus unseating also the valve 10<SP>1</SP>.
