Equipment Used Afloat and Ashore Miniature Tiering Truck—Propeller Type Blower—High Pressure Oil Engine—Pro- tecting Stern Tubes—Flanged Joint—Speed Control—Light Ventilator—Lift Truck MINIATURE tiering truck, 29 inches in width, is of interest to industrialists because it is so well suited to existing narrow aisles in the average shop, store, or ware- house. Stockroom floor space is _ usually squeezed to the minimum so that bins are run as close to the ceil- ing as sprinkler systems permit. Con- sequently the aisles are narrowed to the space an attendant requires to store or remove an order. The tiering truck illustrated, man- ufactured by the Elwell-Parker Elec- tric Co., Cleveland, has a capacity of Pic caucassasteersecacstesrsccnnsaenamaeeieammeeeee eaten Small 3000-Pound Capacity Tiering Truck 3000 pounds. Its 18 by 41 by 7-inch height platform will handle a 24 to 30 by 48-inch skid or container to a height of 63 inches, the overall height being 83 inches for T7-foot doorways or box car entrance. The small machine is an entirely new de- velopment in low capacity industrial high lift trucks, while the auxiliary boom on the fork truck makes the machine serve two purposes of lifting and carrying heavy loads with the man power of one operator. This 3000-pound machine has each important unit found in the 35,000- pound haulage tool, all on a smaller scale. The same safety features and system of control are built to en- able the same operator to drive it if necessary. The system of lifts is by worm gear speed reduction to cables that elevate the cantilever platform. The drive axle is of the full float- ing silent worm gear type fitted with 20 x 5-inch press-on type tires. The trail axle beneath the 7-inch high platform is fitted with 6% x 4-inch tires. All four wheels are steered by means of automobile type ball and socket fitted levers. The truck may be fitted with battery or gas- electric power to perform a full day’s work, with efficiency and dispatch. Error Is Corrected In the January issue on page 53 un- der the heading “Propeller Type Blow- er Will Exhaust Gases” the wrong il- lustration was used. This item is re- published below using tne proper il- lustration. The item covering the cut used incorrectly appears on the op- posite page. Propeller Type Blower Will Exhaust Gases HIS unusual looking piece of | eee is a Westinghouse pro- peller-type blower of special design which is to be installed on a gasoline tanker to exhaust the gases from the pump room to the atmosphere. The blower is turbine driven and is rated at 6000 cubic feet per minute at 4- inch static pressure. The entire unit is of welded steel construction and of extremely simple design. The propeller is three-bladed and is driven by a single-wheel tur- bine having inside buckets milled in the wheel, through a steel shaft sup- ported in grease-lubricated bearings. This is another application of the Westinghouse blower, which is an in- vention of H. F. Schmidt, consulting engineer, and is built at the South Philadelphia works of the Westing- house Electric & Mfg. Co. saan Welded Propeller Type Blower MARINE REVIEw—February, 1931 Announce New Oil Engine without High Pressure MPLOYING vacuum rather than high pressure for vaporizing fuel oil, the new Murray & Tregurtha oil engine has been placed on the mar- ket in 4 cylinder, 65 horsepower and 6 cylinder 110 horsepower models. This is the product of one of the pioneer engine manufacturers, Mur- ray & Tregurtha, Ine., of North Quincy, Mass., established in 1891. This new power plant is not a diesel engine. It is the first of a distinct type in which a nebulizer mechanical- ly processes furnace oil, distillates and diesel oils usually used by die- sel engines of like power. The prac- tically dry vapor resulting from the process carried out in this nebulizer is burned in the engine with clear exhaust, absence of odor, soot, sparks from incandescent carbon or smoke. Because this engine burns a dry vapor there are no deposits or carbon- and-oil mixtures fouling these parts and “caking”’ onto the parts coming in contact with combustion. The heat of vaporization is always well below the “cracking” point of the fuel, hence no carbon deposits can form. Through the use of low cost distil- lates and diesel oils, the cost of oper- ation is cut in half as compared with a gasoline engine of equal power in the same service. New Compound Protects Stern Tubes in Winter HE B. F. Goodrich Rubber Co. have developed a very interesting method of protecting stern tubes from troubles caused by freezing during the winter lay-up of lake vessels. In place of customary grease and other compounds, usually used in the stern tubes between the after stern bearing and the forward stuffing gland, this new compound is free from all oil and grease and contains nothing of an injurious nature to rub- ber, such as is used in Cutless rub- ber stern bearings or on the rubber, as used for shaft coverings. The same method of introducing this compound into the stern tube is used. In the spring of the year when the vessel goes into operation, the water from the service line connected to the stern tube is used to flush out the compound. This material is said t0 cost no more than the materials now used for this service.
