Title: Improvements in and relating to hydraulically-operated lathes
IPC: B23B31/30
Filed: 1939-11-22
Abstract: 533,756. Lathes ; chucks. TOWLER, J. M., and TOWLER, F. H. Nov. 22, 1939, No. 30575. [Class 83 (iii)] A hydraulic lathe has the tailstock centre a moved by a cylinder c to and from the work v such as a shell forging while the chuck w is moved hydraulically in the closing direction by a cylinder f acting against a spring k which introduces sufficient back pressure to ensure that the tail centre engages the work before the chuck jaws are closed. Fluid from a pump or accumulator is supplied to a line n leading to a piston valve o controlling the pressure supply to lines q, r the former leading to the tailstock cylinder space e and the latter through a hollow extension of the chuck draw spindle h to a space j. A line s is in constant communication with the reduced back portion of the tailstock piston b. In the position shown the pressure in the space e overcomes the pressure on the back of the piston b and advances the tail centre. When the tailstock is arrested, the consequent rise in pressure causes the pressure in cylinder j to overcome the opening pressure of springs k and to close the chuck. When the valve o is moved upwards the space e and the cylinder f are both open to an exhaust line t. The pressure in space d then causes the withdrawal of the tailstock while the springs k open the chuck. Specification 532,420 is referred to.

Filed: 1925-12-12
Abstract: 244,768. British Thomson-Houston Co., Ltd., (Assignees of Orr, C.). Dec. 16, 1924, [Convention date]. Refrigerating, compression machines for.-A machine employing sulphur dioxide or like refrigerant and adapted to be mounted on the top cover 4, Fig. 1, of a cooling-chamber, with the evaporator 41 depending into the chamber, comprises oscillating-cylinder compressors 14 driven by an eccentric 27 from the vertical shaft 28 of an electric motor 31, an air-cooled condenser consisting of a gilled copper coil 10, a reservoir 7 for condensed refrigerant, a delivery chamber 8 containing lubricant, and automatic valve devices for controlling the flow of refrigerant to the evaporator and for equalizing the pressures throughout the upper part of the machine when the compressor is stopped. The reservoir 7 is mounted on a base 5 and supports the compressor chamber, which in turn supports the motor. The compressor cylinders have trunnions 15, 16, are flattened where they engage the top 17 of the chamber 7, and are pressed downwards by springs 19. They are single-acting and draw in the refrigerant vapour through cylinder ports registering with pipes 22 reaching nearly to the bottom of suction chambers 21, to the upper part of which the return pipe 20 of the evaporator is connected. Any lubricant leaking downwards from the cylinders collects in the chamber 21 and is drawn back into the cylinders when it reaches the level of the ends of the pipes 22, whereby flow of lubricant down the suction pipe to the evaporator is avoided. The cylinders have flap discharge valves 24 in their ends. The motor shaft has two bearings 29, 30, only, the upper bearing 30 having a catch cup 30<1> leading oil into the bearing through a hole. The evaporator comprises a coil 42 and vessel 41 normally nearly full of liquid, the inlet pipe 40 extending into the liquid space and the return vapour pipe 20 being connected to the top of the vessel 41. The flow into the evaporator is controlled by a float valve 37. The equalizing valve 34, Fig. 2, is held closed by a weighted lever 33 while centrifugal weights 32 are raised during the running of the motor, and closes when these weights fall after the motor stops. The pressures in the chambers 7 and 8 and in the condenser coil are then equalized, and a check valve 51 in the suction pipe 20 closes to prevent back flow of warm vapour to the evaporator. The condenser coil is spaced and supported by bars 47 secured to brackets 46 extending up from the base 5. The compressor chamber has longitudinal radiating vanes 45, and the cylindrical wall of the motor casing 43 has similar vanes 44, which may be of copper fastened as by soldering. A positive circulation of cooling air around the condenser may be provided.

Abstract: 361,074. Sewing-machines. EBERT, F., 11, Brandeggerstrasse, Oberndorf-on- Neckar, Germany. Oct. 21, 1930, No. 31557. [Class 112.] Sack-sewing machines; loop stitching.-A machine for sewing sacks or other coarse or heavy material has the drive of the under-thread looper or loopers constituted as a self-contained unit attachable to and adjustable about a vertical axis on, the machine. The machine is driven in the usual manner by a main shaft 1 extending horizontally in the lower portion of the machine frame 2. The seam is produced by the needle 3 and the two loopers 4, 5. The lower thread looper 4 is driven by the mechanism shown in Fig. 9. This mechanism is carried by a bracket 6 secured to the machine base 7. The rotation of the main shaft 1 is transmitted to the vertically oscillating driving lever 11 by an eccentric 8, connecting-rod 9 and ball pivot 10. The lever 11 has a boss 12 to which is clamped an arm 14 by means of screws 15 disposed in the gripping jaws 16 of the radially split boss 17 of the arm 14. The arm 14 is connected by a link 18 with a lever 19 which has a boss 20 oscillating about an axis 21 of the lower thread looper 4. Owing to the articulated drive 14, 18, 19 the lower thread looper 4, after its advance, stands still until the needle 3 moves up again and the needle loop has opened the duration of the dwell being varied by adjusting the lever 14. Thread eyes 25, 27 -are provided. A rib on the looper 4 keeps the lower thread 23 from coming into frictional contact with the needle thread loop 31. The entire mechanism of the lower thread looper 4 can be turned about a vertical axis to bring the lower thread 23 in front of the needle 3 and a rapid adjustment to various thicknesses of needle effected. For this purpose a pin 33, Fig. 9, passes through the baseplate 7 and serves as the axis of rotation for the bracket 6 which is secured after adjustment by screws 34 working in arcuate slots 35. The looper 5 moving over the table 36 is driven directly from the end of the main shaft 1 by a crank 37, rod 38, ball pivol s 39, lever 41 and looper shaft 40. For two-thread stitching, Fig. 2, an auxiliary loop-taker (not shown) oscillating on the shaft 49, is provided. This loop-taker is driven directly from the looper lever 44 by a connecting-rod 52. The two-thread seam is shown in Fig. 17. To sew on the same machine with three threads, the auxiliary loop-taker is replaced by a thread guide 59 and a third thread 56, Fig. 12. The auxiliary loop-taker and its driving mechanism is removed and replaced by a carrier 58 having two thread eyes 59 disposed at the sides of the path of the thread eye 60 or the looper lever 44. The threethread 'seam is shown in Fig. 23.
