Title: Vices
IPC: B25B1/12
Filed: 1958-09-19
Abstract: 857,116. Vices. GITTINS, W. H. N. Sept. 4, 1959 [Sept. 19, 1958], No. 30003/58. Class 61. In a vice having a quick release mechanism for disengaging the traversing nut from the traversing screw, the quick release mechanism comprises a release bar 18 mounted for pivotal movement about a longitudinal axis which is coincident with the axis of the screw 12, the release bar having a frictional clutch connection 21 with the screw 12 and a range of angular movement about the common axis which is limited by stops 22 which may be located on a bracket 23, on the movable jaw 11 or on the clutch collar 27. The arrangement is such that during a fractional turn of the screw 12 in the direction to open the jaws of the vice the relase bar 18 is carried round with it, engages and moves the nut clear of the screw and then is arrested by the stops 22, whereupon the clutch is caused to slip and the release bar maintains the nut disengaged and clear of the traverse screw so that the movable jaw 11 of the vice is free to be moved directly towards or away from the fixed jaw 10 of the vice. The release bar 18 has a transverse arcuate section 19 which engages a cam surface 20 on the nut 15 causing the latter to be moved away from the traverse screw 12 as the arcuate section 19 of the release bar is interposed between the confronting threaded surfaces of the screw 12 and nut 15. The clutch connection 21 comprises a pair of oppositely loaded spring balls 25 located in a lateral bore in the screw 12, this portion of the screw being encircled by the rotatable collar 27 which receives an end tongue 28 of the release bar 18, and is formed with an internal annular groove 29. A depression 30 is formed in the end tongue 28 for receiving either of the balls 25, slipping of the clutch occurring when the ball 25 is forced out of the depression 30. The movable jaw 11 is carried by parallel guide rods 13 which extend through clearance openings in the body 14 of the fixed jaw 10. In a modification the clutch is located adjacent the bracket 23.

Title: Control system for a rotating clutch-

Filed: 1974-07-09
Abstract: 1457949 Friction clutches CATERPILLAR TRACTOR CO 9 July 1974 [4 Sept 1973] 30355/74 Headings F2C and F2L In a friction clutch for a marine vessel wherein clutch plates 72, 76 are engaged by centrifugal pressure of liquid in a chamber 122 fast with a driving housing 52, 54, 56, the chamber 122 is continuously bled through an orifice 106 and a valve (24) Fig. 1 (not shown) selectively varies the pressure liquid supply 116 to the chamber 122 and thus varies the filling of the chamber and the clutch engagement. The supply pressure liquid 116 additionally acts on the spool 138 of a local exhaust valve which, in the absence of supply pressure, is opened centrifugally to exhaust the chamber 122 rapidly through a duct 112 for clutch disengagement. A restricted passage 140 through the spool 138 limits the rate at which the chamber 122 is filled and thus limits the rate of clutch engagement. The pressure in the chamber 122 acts on the clutch discs 72, 76 through a presser plate 118 which is biased towards the disengaged position by springs 128. As shown in a double clutch for a marine reversing gear the clutch 72, 76 selectively connects the housing 52, 54, 56 to a first, forward drive, output shaft 48 whilst a similar clutch 64, 68 connects the housing to a second, reverse drive, coaxial output shaft 50. A shield 146 prevents lubricating oil for the bearings of the clutch from entering the clutch engaging chambers 122, 124.

Filed: 1968-06-26
Abstract: 1,212,129. Testing internal-combustion engines. A.A. ISAEV. June 26, 1968, No. 30363/68. Heading F1B. [Also in Division F2] An indicator for measuring the maximum pressure in a cylinder of a reciprocating compressor or an I. C. engine, e. g. for tuning and testing purposes, is mountable to the engine (not shown) and comprises a spring-biased piston-actuated shut-off valve 8 which when opened by compressed air supplied through passage 14, chamber 18 and channel 13 to a chamber 12, allows the gases in the cylinder to pass through passages 16, 17 to a throw-over valve 2. The pulsating pressure in the cylinder causes the valve 2 to reciprocate between seats 5, 6 thereby placing the channel 13 alternately into communication with the passages 16, 17 and the chamber 18. The compressed air pressure is then adjusted until the valve 2 stops reciprocating, whereafter the maximum pressure in the cylinder can be determined from the adjusted value of the air pressure. A seal 11 co-operates with piston 10 when the valve 8 is open to prevent leakage between the cylinder and the chamber 12.

Abstract: 230,167. Jackson, W. J. Mellersh-, (Koppers Co.). Dec. 4, 1923. Coke ovens.-In a vertical-flued coke oven having in each heating-wall groups of combustion flues F, G opening at the upper ends into distributing or header flues 25, the two flues 25 associated with upflow and downflow groups of combustion flues are connected bv a duct 26 located at a higher level than the tops of the ovens. Each header flue 25 preferably increases in cross-section, as shown, from the ends to the middle, at which point the connection with the duct 26 is made. The usual top inspection passages 28 are provided in line with the flues, and the portions which intersect the wall between the flues 25, 26 are closed by stoppers 28<a>. The regenerators are arranged beneath and parallel to the ovens, and are connected to the heating-flues by short direct ducts, each heating-flue being in communication with two regenerator chambers so that the oven can be fired either by rich or lean gas. When rich gas is used, half of the inflow regenerators may be used for supplying a neutral diluent gas instead of air.
