Abstract: 562,411. Riveting. STEVENS, A. H. (Independent Pneumatic Tool Co.). Jan. 30, 1943, No. 1603. [Class 83.(iv)] A portable riveting- machine has a poweroperated roller movable along a cam track and so linked to a lever operating a plunger that an increasing mechanical advantage is obtained throughout the stroke. The body 1 of the machine has a selfcontained abutment 4 detachably secured at 6 and carries a main power cylinder 2 closed by a head 8 in which the control valves are mounted and in which is screwed an auxiliary cylinder 10 locked at 43. A bush in the head guides a hollow rod 9, connecting the pistons, flatted at 13a' and ported at 13 so that the cylinder spaces behind the pistons are always in communication even when the piston 7 is close against the head 8. The bush is connected at 27 to a pin 26 on lugs 25, on the front of the piston 7, slotted to receive links 20 connected by a distance piece 32 and carrying a pin 29, carrying a roller 30 and connecting links 19 to a lever 15 pivoted in the body 1 at 16 and having a nose 22 engaging the head of the plunger 5. The plunger is fitted with a retracting spring 24 and is mounted in a fitting 47 interchangeably secured in the body by slots, lugs and keys. A stop (not shown) may be projected into the path of the plunger to restrict its return stroke when operating on short rivets. The links 19 have extensions 37 engaging the sides of the cam 34 to prevent side play. The cam is secured at 35 and dowelled at 36 to the body. The control valve is operated by a lever 79 pivoted , to the head 8 at 80. The valve is returned by a spring to the position shown in Fig. 15, in which the space behind the pistons 7 and 11 is connected to exhaust at 87 and the inlet at 69, 68 for pressure air is connected at 83 to the space between the piston 11 and the head 8 producing the return stroke under pressure from the piston 11 only. As the lever 79 is depressed the valve is raised compressing the spring 74, Fig. 11, and closing the exhaust port 87 and admission port 83. The space between the piston 11 and head 8 is opened to exhaust at 84, 85 and a small port 71 admits pressure air behind the piston 7 and via the hollow rod 9 behind the piston 11 also to start the riveting stroke. The loose sleeve 76 now contacts the plug 78 and is arrested, further movement of the valve compresses the spring 75 also and opens the larger port 70 for the completion of the power stroke. The maximum pressure behind the pistons is limited according to the size or material of the rivet by a conical relief valve 93 adjustably spring-loaded at 94 by a screw cap 95. Air escapes at.96 when the valve opens. The cylinder 10 serves as a grip for one hand in manipulating the machine, the other hand grasping the body 1.

Abstract: 1497872 Soil testing CEMENTATION GROUND ENG Ltd 30 Jan 1976 [16 Jan 1975] 2004/75 Heading G1S [Also in Divisions E2 and F2] A method of testing soil or other similar material at various levels in the soil or other material which comprises the steps of: 1. placing an assembly of a casing, a penetrating member and a drive rod at a' first level at which it is desired to test the soil or other material, the assembly being such that the drive rod is operatively connected to the penetrating member and extends longitudinally through the casing; 2. subjecting the penetrating member via the drive rod to repeated blows urging the penetrating member into the soil or other material while the casing is stationary and observing the penetration in relation to the number of blows applied; 3. driving the casing into the soil or other material until the end of the casing contacts the penetrating member and the penetrating member is at a second level at which it is desired to test the soil; and 4. repeating step (2). In soil testing apparatus for carrying out the above method a cone 2 Fig. 1(1) having a sleeve 3 is first pushed into the ground by driving a casing 5 downwardly using a static or dynamic load. A cap 8, Fig. 1(2) is then placed over a drive rod 4 connected directly to the cone 2 and is driven downwardly by a weight 9 until the cone alone penetrates further into the ground Fig. 1(3). In one test the number of blows from the weight required to drive the cone into the ground is recorded for every three inches up to a maximum of eighteen inches. The cap 8 is then removed and further lengths of drive rod 4 and casing 5 are added. A weight 10 attached to the outside of the casing, Fig. 2, may then be raised upwardly along the casing and dropped on to an anvil 12 mounted .on a clamp 11 fixed to the casing, in this way the further casing is driven into the soil. When it is desired to remove the casing from the ground, hooks 13 are engaged so that the means for raising the weight 10 can be used to draw the casing 5 from the ground. In Fig. 3 the lower end of cap 8 itself strikes the anvil. In Fig. 4, a special coupling member 19 (see also Divisions E2 and F2) is used to connect the cap 8 and casing 5 and the weight acts directly on the cap. In Fig. 9 a permeability cell 38 is provided at 39, water being supplied to the soil through holes 40 in the casing through conduits 41 and splined grooves 42 in the casing. The cell is exposed to the coil when the cone 2, 3 is driven into the ground beyond the casing. In another construction the cell comprises a plurality of grooved washers in a stack, the grooves providing passages from the interior to the exterior of the assembly so that water may be passed through the cell and into the surrounding soil, the water pressure and rate of flow being observed.
