Abstract: 1,005,965. Scotch blocks. OFFICINE DI COSTAMASNAGA S.p.A. June 29, 1962 [Nov. 2, 1961; Dec. 22, 1961; May 7, 1962], No. 24985/62. Heading F2E. A device for wedging or chocking a wheel of a vehicle carried by a surface which has a plurality of holes comprises one part rigid with a wedge or chock member for engagement with a vehicle wheel, another part adjustably secured to the first part and including expandible means for engaging in any one of the holes and actuating means for expanding the expandible means when the latter is engaged in one of the holes whereby the second part is secured to the surface Means, Fig. 1, for coupling the fixed section 100 of a device to the surface 117 of a wagon comprises a fixed jaw 107 provided on a plate 106 and which has pivoted thereto a lever 114 carrying an eccentric 115. The latter on swinging movement of the lever 114 forces a movable jaw 111, pivoted at 110 on the projection 109 of the plate 106, into a position where a projection 112 underlies projection 118 formed in the holes 120 in the wagon platform. Projection 108 on the fixed jaw also underlies the projection 119 to releasably couple the fixed section to the platform. In an embodiment of the device, Fig. 2, the fixed section is coupled to the platform 201 by means of a fixed jaw 218 having screwthreadably received therein a cylindrical body 224 having shoulders 226, 227 thereon between which project the bifurcated end of movable jaw 221. The latter is pivoted at 220 and is moved to couple the fixed section to the platform on rotation of a square spindle 231 by a hand wheel 232. The spindle 231 passes through a square orifice 229 in the body 224 and on rotation thereof causes the body 224 to be screw-threaded into the fixed jaw 218 to thereby pivotally move the jaw 221. The end of a pivoted cam lever 206 is in the shape of a V and co-operates with a tube or wire 214 secured to the fixed section to adjustably connect the latter to the movable section comprising the housing and scotch block 240. The lever 206 may be moved away from the tube 214 by a spring-loaded lever 207. In a further embodiment, Fig. 6, the movable jaw 26, controlled by a lever 263, is formed with an end 271 which co-operates with a rack 254 secured to the movable section.

Title: Improvements in sterilizing apparatus
IPC: A61L2/07
Filed: 1936-09-14
Abstract: 481,373. Thermal switches. SPARKHALL, J. B. Sept. 14, 1936, No. 25032. [Class 38 (v)] [Also in Group VI] A device for sterilizing-chambers or other enclosures comprises means whereby a measured quantity of sterilizing liquid is discharged into an electrically heated evaporating pan, and the heat is switched off after the lapse of a predetermined period by a thermostatic control member. As shown, the device comprises a casing 1 supporting an evaporating pan 3 into which liquid is discharged when the push rod 20 of measuring device A is pressed forward into the position shown in Fig. 3 by hand or by closure of the sterilizer door. The heating lead 22 is connected to a switch 23 actuated by a pivoted lever 24, loaded by a spring 26 which tends to maintain it in the position shown in Fig. 5, in which position the switch is open. The lever 24 is formed with a notch 27 with which a projection 28 on a snail cam 29 is adapted to engage. The cam is rotatably mounted on an extension of a tubular casing 33 in which is disposed a heating element 34 in series with the switch 23 and the heating element of the evaporating pan. A bimetallic thermo-sensitive strip 35 is wrapped round the casing 33, one end 35a being secured to the casing, and the other end 35b to a bushing 29a on the cam 29. When the heater 34 is cold, the cam is in such position that the lever 24 is raised at the end of its longer arm and closes the switch. As the temperature of the thermostat heater rises, the cam is rotated in a counterclockwise direction (Fig. 5) by the bimetallic strip until the projection 28 registers with the notch 27 and the lever drops into the position shown in Fig. 5, thereby opening the switch. As the bimetallic strip cools, it tends to rotate the cam to its original position, this however being prevented by the interengagement of the notch 27 and projection 28. A resetting device consists of a pivoted lever 36, fig. 2, carrying a trigger finger 38a adapted to engage with a collar 39 on the push rod, so that on the inward movement of the push rod 20, the end 36b of the lever is depressed, the end 36a being thereby caused to lift the lever 24 to allow the cam to return to its "cold" position, thereby to open the switch 23. The trigger finger 38a is pivoted so that it will merely be rocked by the collar 39 ''on the outward movement of the push rod 20.
