Title: Mast assemblies for lift trucks
Inventor: MCINTOSH RICHARD FREDRICK
IPC: B66F9/08
Filed: 1968-07-30
Abstract: 1,222,021. Masted lift-trucks. CLARK EQUIPMENT CO. 30 July, 1968 [21 Aug., 1967], No. 36227/68. Heading B8H. Each movable mast section of a lift truck mast assembly is adapted to be lowered to a position lower than its normal lowermost position to expose the guide rollers of the mast assembly for maintenance. In the embodiment shown, Fig. 5, a cross-bar 102 secured between the movable I-section uprights 46 is secured to a bracket 89 at the upper end of a multi-stage ram assembly 74 and the lifting carriage 48 is secured to chains which pass over sprockets on a crosshead secured to a part of the ram assembly and are anchored to a movable cylinder part of the assembly, Fig. 2 (not shown). The arrangement is such that on extending the ram assembly, the carriage 48 is raised to the top of the uprights 46 before the uprights are raised. To expose the mast assembly guide rollers, the ram assembly is extended sufficiently to raise the carriage to the top of the uprights 46 and to raise the uprights 46 slightly. The carriage is then secured to the uprights 46 by a chain 162 and the cross-bar 102 is disconnected from the bracket 89 on the ram assembly by removing the bolts 106. The uprights 46 are then lowered to a position in which they extend below the lower ends of fixed uprights 42, thereby exposing guide rollers 124, 126 mounted on stub axles secured to the web portions of the uprights 42, 46, respectively. In modifications, instead of securing the lifting carriage to the adjacent mast section, the mast section may be raised and supported by an overhead hoist or by a jack during the disconnecting of the ram assembly from the mast section. In a second embodiment, Figs. 11-20 (not shown), a similar arrangement for exposing the guide rollers is applied to a triple-section mast assembly.

Title: Improvements in spraying and injecting device for internal combustion engines employing liquid fuel
IPC: F02M61/10
Filed: 1929-11-26
Abstract: 342,822. Fuel-injectors. TARTRAIS, E. H., 20, Rue GrÚtry, Montmorency, Seineet-Oise, France. Nov. 26, 1929, No. 36266. Convention date, Nov. 26, 1928. [Class 7 (iii).] In a liquid-fuel nozzle wherein valves in the nozzle are opened by the fuel pressure, the nozzle comprises a body 4 with a flat valve seat 6 upon which a main valve 1 seats. A movable sleeve 7 is mounted in the body and has a knife-edge 3 seating on the flat seat 2 of the valve 1, and a spring 9 is arranged between the sleeve 7 and a nut 10 on the valve stem and subject to the action of a closing spring 11. A conduit 13 is provided in the valve stem and communicates with the seats by holes 14 or grooves. An ejection pump of the kind described in Specification 173,224, [Class 7 (iii), Internal-combustion engines, Carburetting- apparatus &c. for], may be used. When the pump starts to deliver, the valve 1 and sleeve 7 move together until the shoulder 16 engages the body of the nozzle. The knife-edge 3 leaves the seat 2 and the fuel is suddenly sprayed in the form of a thin sheet. The fuel conduit pressure is released, the compressed fuel in the chamber 15 expands, and the valves return to the position shown in Fig. 1. Owing to variations of pressure in the space 15 and the action of the spring 11, the valve alternately opens abruptly and recedes thereby producing a series of partial injections according to the speed until the discharge is effected. The recession of the valve prevents carbon deposits around the discharge orifice. In a modification, Fig. 3, the sleeve engages a flat or tapered seat 18 on the main valve ; a spring 19 in tension is used ; the valve stem is grooved to supply the oil. In other modifications, the spring 9 is dispensed with, and the relative movement between the sleeve and valve is effected by the pressure on differential areas on the sleeve. In a further modification, the reaction spring acts on the flange of the sleeve. In another construction, the inertia of the oil column effects the sudden discharge of fuel, the cylinder pressure returning the valve to its seat. In the construction shown in Fig. 9, the reaction spring is eliminated, and the sleeve 7 is provided with differential areas.
