Title: Improvements in or relating to gas compressors
IPC: F04D17/18
Filed: 1935-12-13
Abstract: 455,257. Centrifugal compressors. BERGMANN, C. A., 2012, North 38th Street, Milwaukee, Wisconsin, U.S.A. Dec. 13, 1935, No. 34658. [Class 110 (i)] [See also Group XXIX] Air from ducts 56 is entrained in liquid, circulating through a rotor 47, 48, and is discharged through floatactuated valves 59. The air is conveyed from an air cleaner 53 tu the intake slots 56 via a non-return check valve 54 and passages 30, 55. The liquid is conveyed from a cooler 41 to stationary ducts 46 via passages 84, 83. Due to the rotation of the rotor 47, 48, water admitted to the duct 46 is projected through ducts 47. Air from the intake slots 56 is entrained in the water and the mixture of air and water passes through the compression ducts 47. The air is discharged when it reaches a separating conduit 52 through float valves 59, and passages 62, 37. It then passes through a bellows 35, a non-return check valve 38 and into a pipe 39 leading to a reservoir 40. The valve float 59 comprise a short arm 64 made of heavy material and a longer arm 63 of lighter material. The compressor is regulated by transferring the water from the ducts 46, 47, 52 to an annular space 67, within the rotor. As soon as the maximum air pressure is reached in the reservoir 40, a piston-controlled valve 69 is moved to the right against the tension of a spring 70 and compressed air passes through a pipe line 74 to operate a valve 76. Water then escapes through the valve 76 into the space 67 and compression ceases. As soon as enough air has been taken from the reservoir 40, the spring 70 moves the valve 69 and connects the pipe line 74 with atmosphere. The water in the space 67 is then forced back into the ducts and the compressor again begins to compress air. In a modification the water which is separated from the air is forced through nozzles 118, Fig. 9 into stationary-ducts 103.

Filed: 1945-12-21
Abstract: 605,409. Railway track brakes. GENERAL ELECTRIC CO., Ltd., and MARSHALL, C. H. Dec. 21, 1945, No. 34763. [Class 103 (i)] A track brake for railway wagons comprises an elongated slipper mounted parallel or substantially so to the track and capable of being raised from an inoperative position to a position such that it will engage the bottoms of the horn stays at one side of a wagon passing over it. A second slipper may be disposed parallel to the first to operate on the horn stays on the other side of the wagon. In one form, Figs. 1 and 2, as fitted to a wagon tippler, the slipper 10 is of channel section stiffened by a rolled steel joist 11 and is mounted for vertical movement on two sets of four parallel links 12 pivoted to the lifting arms 14 of the tippler and to brackets 13 on the joist. The slipper is supported by rollers 15H, 15A on levers 15 secured to a shaft 16 carried by bearings fixed to the foundations of the tippler, an arm 26 on the shaft being connected by an adjustable tension link 25, a lever 23 and a compression link 22 to an arm 21 on the shaft 19 of a hand lever 18. The arm 21 and link 22 form a toggle linkage, the mechanical advantage of which increases as the lever 18 is depressed to raise the slipper into engagement with the hornstays 28. A stop 29 receives the braking reaction from the slipper. In a second form, Fig. 4, the slipper 10, 11 is inclined downwardly towards the direction of approach of the wagon and is carried by two pairs of parallel levers 32 pivoted in fixed brackets 30. One pair of levers is rigidly connected to a hand lever 18 or pedal 18A, and a stop 31 limits downward movement of the slipper. The levers 32 are inclined towards the direction of approach of the wagon so that the force applied by the hornstays tends to raise the slipper and so increase the retarding effect. The slipper may be operated by screws or hydraulic means.

Title: Improvements relating to vises
IPC: B25B1/10
Filed: 1954-12-06
Abstract: 763,672. Vices. GIPPERICH, H. Dec. 6, 1954 [Dec. 7, 1953], No. 35280/54. Class 61 [Also in Group XXIV] A quick acting vice has jaws 1, 2 which are relatively movable by means of a spindle having two threaded parts 4, 5 of different pitch in which the rapid adjustment of the movable jaw is effected by the thread 4 of coarser pitch and the final clamping is effectedsimultaneously by both threads acting on the jaws differentially. A flange-like stop 3 is provided on the spindle at the end of the threaded portion 4. A threadless portion of the spindle is passed through a bore in the clamping jaw 2. A threaded bush 8 is inserted in this bore so as to be axially displaceable therein. The internal thread of the bush 8 corresponds to the finer pitch thread 5.. The bush is provided with a flange like abutment 12 and is secured against rotation by a pin 9 engaging in a groove in the jaw 2. A compression spring 10 acts on the flange 12 and urges the bush 8 to the right until the pin 9 abuts the end of the guide groove. A helical compression spring 13 arranged between the jaw 2 and a head 14 on the spindle tends to displace the jaw 2 in the direction of the jaw 1 and holds the jaw 2 against the flange 3 of the spindle. The thread 5 is normally out of engagement with the threaded bush 8. When the spindle is turned by means of a grip bar 16 it is screwed within the jaw 1. by means of its steeper thread 4. During the axial displacement of the spindle the jaw 2 is carried along by the spring 13 until it encounters the body to be clamped. The thread 5 of finer pitch then comes into engagement with the threaded bush 8 and is screwed into the latter. As the threads 4, 5 have different pitches, the bush 8 is displaced towards the left at a speed dependent upon the difference in pitch of the two threads. On further rotation of the spindle the flange 12 of the bush 8 finally abuts against the jaw 2 and the bush carries the jaw 2 along and presses it against the body to be clamped.
