Title: Improvements relating to control of apparatus operated by pressure fluid
Inventor: GRIMSLEY GEORGE FREDERICK
IPC: F15B11/20
Filed: 1953-06-26
Abstract: 780,963. Ironing presses; finishing fabrics. GRIMSLEY & CO. LEICESTER, Ltd., WARBURTON, B. L., and MARVIN, M. J. Sept. 27, 1954 [June 26, 1953], No. 17782/53. Classes 42 (1) and 138 (2). [Also in Group XXIX] Fluid pressure operated apparatus in which operations are carried out sequentially by the application of pressure fluid to appropriate parts of the apparatus is provided with control means comprising a cam unit 7 guided for rectilinear reciprocating movement, the cam unit 7 having one or more cam edges 11, 12 disposed obliquely to the direction of travel of the unit, valves 13 ... 17 for controlling the application of the pressure fluid to the appropriate parts of the apparatus in a predetermined sequence, and a part associated with the valve element of each of the valves and adapted to run on or off one or more of the cam edges, as a result of the travel of the cam unit, thereby to operate the associated valve. The invention is described as applied to a garment pressing machine but may also be applied to nylon hose and fabric finishing machines and machines for preboarding hosiery. In the example shown in the drawing the cam unit 7 is moved by the pressure fluid, and means are provided for varying the speed of the cam unit and for adjusting the positions of the valves relatively thereto. By depressing two hand levers 23, 24 compressed air is admitted from a pipe 18 through valves 21, 22 to a cylinder 25 containing two pistons 30, 31 connected to levers 3, 3<SP>1</SP> respectively. Lever 3 effects partial closing of the head 2 of the press, whilst lever 3<SP>1</SP> effects the final closing movement on to the buck 1. As it descends the head 2 operates a change-over valve 33 to supply compressed air to a port 35 instead of a port 34 in a cylinder 4 containing a piston 5. The piston 5, a rod 6 and the cam unit 7 then move slowly to the right under the braking action of a dashpot arrangement 8, 9 regulated by control valves 36. Alternatively the cylinder 4 and piston 5 may be utilized as a dashpot arrangement in place of the arrangement 8, 9, by providing a non- return valve 43 and an adjustable bleeder valve at 44. Valve 13 controls the supply of pressure fluid to a double-acting air cylinder 39 the piston of which controls valves (not shown) for admitting steam to the buck 1. The application of suction to the buck 1 is controlled by a single acting cylinder 40, the valve 14 acting to open and valve 16 to close the buck to suction. Valve 16 effects a part opening of the head 2 and valve 17 the completion of this opening movement. By the adjustment of trip rods controlling valves 16 and 17 so that the valve 16 opens at the same instant that valve 17 closes, the head 2 will open fully in one operation. The cam unit 7 may alternatively actuate electrical micro-switches arranged so that the current is relayed to solenoids for operating the control valves.

Title: Improvements in fire detecting thermostats
IPC: H01H37/56
Filed: 1944-09-19
Abstract: 589,655. Thermostats. JAMESON, R. P. Sept. 19, 1944, No. 17890. [Class 64 (ii)] [Also in Group XXXVII] A fire-detecting thermostat comprises a bi-metal coil 1 fixed at one end, and at the other attached to a rotatable rod 2 upon which is mounted a second bi-metal coil 4 such that on a rise in its temperature, it will rotate in a direction contrary to that of coil 1. The free end 5 of coil 4 lies between two fixed contacts 9 and 10 (not shown), and is normally in engagement with one contact 9, the tension between the points 5 and 9 being adjustable by means of a calibrated wheel 15 carried on a spindle 14, which is connected to the coil 1 by the bush 12. Coil 5 is shielded from the atmosphere so that on a rapid rise in temperature, coil 1, the rod 2, and hence coil 5 are rotated, and contact 5 breaks from contact 9, eventually engaging contact 10. On a slow rise in temperature coil 5 rotating contrary to coil 1 keeps contacts 5 and 9 together, a fusible element 18 in the electric circuit ensuring that a certain maximum value of the temperature will not be exceeded.

Filed: 1943-10-30
Abstract: 569,211. Electromagnetic switches. RUSSELL, E. S. Oct. 30, 1943, No. 17973. [Class 38 (v)] Upon energization of a solenoid 1, a totallyenclosed core 8, which also acts as the piston of a dash-pot, moves slowly to the left thereby increasing the magnetic flux across a gap 5 till an armature 12 is attracted to the gap against the action of a spring 18 and contacts 17 are operated. In the form shown a cam surface 15 opens the contacts 17 and the armature is held latched. The opening of contacts 17 breaks the circuit of coil 1 as well as a load circuit so that the core 8 quickly returns to the right under the action of a spring 9, a non-return valve 10 allowing fluid to flow through a central passage in the core. The device is then ready for the next operation which may be started by pulling out the knob 14 fixed to the armature 12 whereupon the contacts 17 close and the solenoid 1 is again energized. The device may be used in conjunction with an electric toaster to time the latter.

Filed: 1923-07-18
Abstract: 224,581. Invernairn, (W. Beardmore), Lord, and Chorlton, A. E. L. July 18, 1923. Oil, catching and removing. - In a lubricating system for internalcombustion engines employing crank - case compression, lubricant supplied to the bearing between the piston and the connecting-rod is returned therefrom to a collecting device in the crank case, the supply and return passages and the collecting device being so arranged as to form a substantially closed circuit, whereby escape of oil into the interior of the crank case is prevented. Oil forced through a passage G in the crank pin D to a groove G<2> in the big-end C<2> passes through a central passage H in the connecting-rod C to the bearing between the connecting-rod and a member B fixed to the piston A, the member B being arranged as described in Specification 221,911, [Class 122 (i), Engine and like cylinders &c.]. Spring-pressed scrapers prevent leakage of oil at the top of the bearing. The oil is caught at the ends of the bearing by flanges J<2> and passes through passages K<1> to a passage K in the connecting-rod surrounding the passage H. The passage K communicates with an outlet K<2> from which the oil is thrown, being caught by a lip M<3> on an annular box M mounted on the crank disc E and being led into the interior M' of the box, whence it is thrown through holes M<4> into a, collecting ring N fixed in the crank case. Opposed vanes M<2>, N<1> and troughs N<3> prevent the escape of oil, which is drained away through an outlet N<2>. Oil leaking from the big-end is also caught by the lip M<3>. Specification 27033/13, [Class 12 (ii), Lubricating passages &c.], also is referred to.
