Title: Improvements in or relating to the withdrawing or retracting of screw threaded spindles
IPC: B29C33/20
Filed: 1927-02-24
Abstract: 291,492. Dunlop Rubber Co., Ltd., Willshaw, H., Lee, R. F., and Cannan, J. A. Feb. 24, 1927. Tipping wagons. - A substantially vertical screw-threaded spindle of steep pitch is held from rotation, so that it may be advanced to a raised position, by rotation of a nut and is adapted to be released from such constraint, when in the raised position, to allow it to run down within the nut by its own weight with or without the assistance of a spring. The device may be applied to tipping members of trolley trucks &c. and is described as applied to moulding and vulcanizing apparatus. The spindle 5 is mounted in threaded engagement with the hub 8<a> of a gear wheel 8 carried by a fixed bracket 13 and meshing with a skew pinion adapted to be rotated by a hand crank 6. When the apparatus is closed, rotation of the spindle is prevented by engagement of a polygonal head 9 thereon with a slot 10 in an extension of an upper hinged part, so that, when the crank 6 is actuated to rotate the nut, the spindle advances, the pyramidal end 14 thereof withdrawing a catch 15 and forcibly separating the parts whereon, by manual pressure, the upper part is swung clear, thus removing the rotative constraint upon the spindle which then runs down within the nut, its fall being cushioned by a rubber &c. buffer 16, a dashpot &c. The descent of the spindle may be assisted by a spring stressed in the advance. Rotation of the spindle may alternatively be prevented by a catch adapted to engage a keyway therein and to be released manually or tripped automatically upon the advance of the spindle.

Abstract: 807,344. Prepayment meters. WATT, F. P. May 8, 1957 [Feb. 21, 1956], No. 5257/56. Class 27 A gas or electricity meter has, in addition to the usual total consumption index, an index 44 which cumulatively totals the number of coins inserted so that its indication is ahead of the total consumption indication by the amount of gas or electricity for which prepayment has been made, the index being calibrated in terms of the units of gas or electricty. An inserted coin depresses a slide 34 to cause a pin 35 to move in a slot 36 in a pivoted dog 37 and the nose of the dog engages a toothed wheel 38 on the same spindle 39 as a planet wheel 40. Rotation of a handle 33 will then cause the planet wheel to rotate a sun wheel 41 on a shaft carrying toothed wheels 50 and 42. The wheel 50 drives the index 44 and the wheel 43 drives a wheel 20 connected by a one-way clutch 21 to a shaft 17 having a slow-pitch helix 18, a quick pitch helix 19 and a wheel 16 engaging a worm 15 on a shaft 14 connected to the measuring-out mechanism. Rotation of the shaft 17 one way or the other by the handle 33 or the measuring-out mechanism moves a traveller 24 on a shaft 25 and a stub shaft 26 on tine traveller opens or closes a stop valve in the meter inlet.

Abstract: 376,679. Lubricating internal-combustion engines. DILKS, W. H., 1033, East 9th Street, Los Angeles, U.S.A. Feb. 27, 1932, No. 5923. [Class 12 (iii).] Lubricant is drawn into the induction manifold 11 of an internal-combustion engine from a reservoir 30 through a pipe 32 and a vacuum chamber 16, which latter has an air inlet 18, 24 which is normally closed by a ball valve 20 adjustably loaded by a spring 21 but which is opened when the vacuum in the chamber exceeds a predetermined maximum, so as to maintain the vacuum approximately constant. The chamber 16 is formed by a glass bell 15 mounted on a base 13, in which latter the passages 18, 24 are formed. The chamber 16 communicates with the manifold 11 through a minute passage 28 in the base, a passage 27, and a tube 26, and the pipe 32 has a fitting 33 secured in the base and is continued into the chamber 16 by a bent-over tube 36 which has a wire restriction 38 therein. Lubricant drips. from the tube 36 into a shallow recess at the top of the passage 18. Filtering material 35 is arranged within the fitting 33. The reservoir 30 may be either above or below the chamber 16, the restriction 38 preventing siphoning. Alternatively, the pipe 32 may lead from the engine crank-case, or, where the oil in the crank case is continually forced through a filter, the pipe 32 may lead from the return pipe from the filter.

Title: An automatic system for controlling the temperature of an enclosed space
IPC: F24F5/00
Filed: 1950-03-09
Abstract: 671,254. Automatic temperature control systems. VAPOR HEATING CORPORATION. March 9, 1950 [March 17, 1949], No. 5980/50. Class 38 (iv). Apparatus for controlling the temperature of an enclosed space, e.g. a railway car, is such that a cooler may come into operation immediately the heaters have ceased to function and comprises an outside thermostat A, floor heat thermostat B, overhead heat thermostat C, No. 1 cooler thermostat D, and No. 2 cooler thermostat E. If the outside temperature is below 50‹ C. the relay A<SP>1</SP> is de-energized, rendering thermostat D, and E, inoperative. If, however, the outside temperature rises above 50‹ C., relay A<SP>1</SP> is energized, making thermostats D, E ready for operation. When the temperature inside the car is below a predetermined value both floor and overhead heat are available since relays Bl and C<SP>1</SP> are energized. The solenoid-closed floor heater valve coil 34 is de-energized and the solenoid-opened overhead heater valve 19 is energized over relay C<SP>1</SP> contacts 54. When energized the relay C<SP>1</SP> also opens contacts 59, breaking the circuit to the auxiliary heater 58 of the thermostat B and closes contacts 60, adding a small amount of auxiliary heat to the auxiliary heater 57 of thermostat C to effect cycling. Thus both thermostats B and C are cycled and the arrangement is such that the floor and overhead heaters operate intermittently. When the temperature outside is above 50‹ C. and inside above the predetermined value, No. 1 cooler thermostat D operates and relay D<SP>1</SP> becomes energized, breaking contact 44 to render ineffective the floor heater thermostat B. Contact 76 is pulled down to energize a floor heat lock-out solenoid 79 controlling a main valve to the floor heaters, contact 84 is pulled down to energize relay 88 to operate the refrigerant compressor motor, contact 89 is pulled down to energize No. 1 cooler valve 29, and contact 80 is pulled down to add a small amount of extra heating current to the auxiliary heater 69 of thermostat D so that if the temperature falls slightly below the predetermined level the overhead heater control C, C<SP>1</SP> may operate without the cooler control D, D<SP>1</SP> becoming inoperative. If, however, the temperature continues to rise, e.g. another 2‹ C., thermostat E causes operation of relay E<SP>1</SP>. This causes energization via contacts 102 of No. 2 cooler valve 30, closure of contact 100 ensuring the supply to relay 88, closure of contact 100 ensuring the supply to the floor heat lock-out 79, and closure of contact 92 energizing an overhead heat lock-out solenoid 22 controlling a main valve to the overhead heaters. A contact 45 is broken further, ensuring the ineffectiveness of thermostat B during a cooling cycle.
