Title: Improvements in or relating to clamps for fixing dress guard stays on the axles of perambulators or the like
Inventor: SPENCER JAMES
IPC: B62B9/00
Filed: 1955-05-10
Abstract: 784,800. Clamps. SPENCER MANUFACTURING CO. (TENBURY), Ltd. Jan. 16, 1956 [May 10, 1955], No. 13448/55. Class 44 A clamp for mounting a stay bar of a dress guard on an axle 6 of a perambulator or the like comprises two clamping arms 1 captively but movably held in grooves 5 between two metal strips forming the stay bar'so that the arms are held in spaced relation whereby the axle can be engaged between the clamping arms prior to clamping and a clamping bolt 7 for passing through the arms for tightening the arms on the axle. In the construction shown in Figs. 1 to 3 the stay bar is made from two metal strips 3, 3a each of which is formed with a pair of transverse grooves 5 at one end, the grooved ends being riveted together so that the grooves are aligned in pairs to receive the clamping arms 1. Each clamping arm is made from a strip of metal bent into an elongated open loop the legs of the loop each being bent to U-shape to form inset grooves 2 on each side. The inset grooves 2 engage the bottoms of the grooves 5 so that the arms are captively but movably held in the grooves 5 with sufficient space between them so that the axle can be passed between the clamping arms. The inner ends of the grooves 5 are bent to form inclined shoulders 5a and when the bolt 7 is passed through the loops of the clamping arms and the clamping arms are drawn together by the bolt and its nut, the legs of the clamping arms ride up the inclined shoulders to permit the clamping movement of the arms. In a modification the grooves 5 can be formed in one of the metal strips 3 or 3a only. In a further modification the grooves 5 are inclined. so that the clamping arms are normally held at an inclination to each other instead of being parallel to each other. The stay can also consist of an elongated strip and a short strip riveted to the elongated strip at its centre, one or both of the strips being bent to form the grooves 5.

Patent GB-135102-A (GB)
IPC: F01K13/02
Abstract: 135,102. Ljungstr÷m, F. March 21, 1919. Cooling parts.-Means for cooling one or more idle-running turbines of installations in which occasionally one or more of the turbine rotors are rotated without doing work comprise arrangements for sucking air or steam through such turbines in a direction opposite to the normal direction of flow of the driving fluid. In this way, excessive heating by the friction of the remaining gas or steam against the blades of idle-running turbines is avoided. In one arrangement, a main turbine 1 for forward driving and a reverse turbine 2 on the same shaft are supplied with live steam from a pipe 5 through pipes 3, 4 and valves 7, 8 respectively. These valves are coupled to other valves 14, 16 so that when one valve of a pair is open the other is shut. If, therefore, the main turbine 1 is working, the valve 7 is open but the valve 14 is shut and the valve 8 is shut but the valve 16 is open and an ejector 10 causes suction through aT-tube 9 and the pipe 4 to cause cooling steam to flow from the exhaust 15 through the turbine 2 in the reverse direction to normal and out through the exhaust pipe 12. The ejector 10 is connected with the water supply through a pipe 11. In another form, the turbine to be cooled is driven by gearing or by another machine and somewhat similar valve, and ejector arrangements are described. If the exhaust steam used as a cooling medium is not saturated, any other wet steam or, if required, live steam, may be employed. Air may also be employed as the cooling medium, in which case a separate air supply pipe and shutting-off devices are provided.
