Title: Portable extensible conveyor
IPC: B65G23/44
Filed: 1954-08-13
Abstract: 805,462. Endless belt conveyers. TRIGGS, W. W. (Joy Manufacturing Co.). April 22, 1955 [Aug. 13, 1954], No. 23616/54. Class 78 (1). In a portable extensible belt conveyer, including a pair of supports 2, 4 engaging the belt 6 at respective terminal portions, means 'for effecting relative movement of the supports towards one another, and power-operated belt take-up means on one of the supports, the arrangement is such that the control means is operated to actuate the take-up means whenever the means for effecting said relative movement is operated. As shown, the take-up means is provided on the support 2 and includes an operating cylinder 80 supplied with pressure fluid by a pump 112 driven by a motor 138. A manually-operated valve 101 diverts fluid to a return line 130 when it is desired to relieve the belt of tension. The means for effecting the relative movement between the supports includes a motor 68 on the support 4 which drives endless tracks by which that support travels over the ground. Motor 68 is manually controlled by a reversing switch 212. The operating lever 214 of this switch, which is movable manually between forward and reverse positions, is connected by a mechanical link 224 with a switch arm 208 such that when the lever 214 is in reverse position in which the motor 68 is driven to drive the support 4 rearwardly towards the support 2, the arm 208 is moved towards a contact 204 to complete a circuit to a relay 192. Energization of the latter bridges contacts 194, 196 to energize a further relay 148, which, in turn, completes a circuit to the motor 138. When the lever 214 is moved to neutral or forward position, causing relay 192 to be de-energized, a subsidiary circuit comes into operation by which relay 148 may be maintained, energized either directly through contacts 164, 166 of a manually - operated change - over switch, or through contacts 164, 160 of the change-over switch and a pressure-responsive switch consisting of fixed and movable contacts 158, 156 respectively, the latter being moved by a diaphragm 154 in accordance with the pressure of the fluid in cylinder 78, the diaphragm being disposed in a chamber 150 connected by a line 152 with the supply line 98 to the cylinder. When desired, the maximum pressure in the cylinder 78 may be limited by opening a manually-operated valve 134 which connects a pressure-relief valve 136 between the cylinder and the return line 130. In the modification shown in Fig. 7, energization of relay 192 additionally causes energization of a solenoid 234 which opens a valve 232 disposed between the pressure-relief valve 136 and the return line. When the lever 214 is in neutral or forward position and the relay 192 is consequently de-energized, the valve 232 is closed and the maximum pressure in the cylinder 78 is determined by a further pressure-relief valve 228 connected in parallel with the valve 136 and set to a higher pressure than the latter. Specification 807,068 is referred to.

Title: Improvements in rolling stock for rail and tramways
IPC: B61F3/16
Filed: 1922-09-06
Abstract: 207,872. Barbey, C., and Venables, R. E. S. Sept. 6, 1922. B o g i e s; springs, arrangement of. - In a railway vehicle bogie the wheels on each side are mounted independently of those on the opposite side in longitudinal frames which are linked together by transverse members to form an articulated parallelogram so arranged that the vertical and transverse stresses between the wheels are transmitted by the transverse members, while the longitudinal frames when displaced turn about vertical axes falling on or near the rails. In the construction shown in Figs. 1 and 2, each wheel 1 is separately mounted in a longitudinal frame 2 pivoted at 3 to the transverse channelled members 4, which complete the parallelogram and are provided with guides 5 for the sides 6 of the frames 2. Each wheel 1 thus turns about a virtual pivot located over the point of contact of the wheel and rail. The body of the vehicle is preferably mounted on side bearings 8 on a second parallelogram formed of longitudinal members 9 and transverse, members 10 and supported from the frames 2 by springs 12 and depending rods 14 passing through the pivots 3. An intermediate longitudinal bar 16 connecting the members 10 is supported at its ends 17 in blocks 18 capable of vertical movement between. guide-blocks 19 carried by the transverse members 4, so that the two parallelograms undergo the same lateral displacements but at the same time are permitted a relative vertical displacement. In this construction, when the wheel parallelogram is deformed, e.g. on the vehicle traversing a curve, a slackening of the gauge in the direction at right-angles to the wheels occurs as indicated in Figs. A, A<1>, ivhere A represents the wheel frames and C the transverse members. The full gauge can, however, be maintained by allowing the wheel frames a sliding movement relative to the transverse members, providing sufficient play at the pivots, and arranging a centre bearing on a member connecting the transverse members C, e.g. as indicated in Figs. E, E<1>. A four-wheeled truck constructed on the principle of these two diagrams is shown in Figs. 6 and 10. The central member comprises an intermediate part f and end parts c connected by links h and provided with co-operating guidemembers f<2>, c<1> to allow a relative vertical movement. Each side member or longitudinal frame comprises an intermediate part e connected by springs d and links k to the wheel frames a which have inwardly-projecting extensions a<1>. The extensions a<1> slide on bolts b, b<1> in the transverse members c and the inward projections on the members e slide in guides on the part f. The body itself is supported by a fixed central pivot g on the part f, and by side pins g<1> carried by the bolster and slidable to a small extent relative to the parts e. Specifications 4399/86 and 11254/11 are referred to.
