Abstract: 352,983. Supplying fuel by direct injection. PACKARD MOTOR CAR CO., 1580, East Grand Boulevard, Detroit, Michigan, U.S.A. March 11, 1930, No. 7941. Convention date, March 25, 1929. [Class 7 (iii).] Liquid fuel is circulated under low pressure in a closed circuit from which the charges for individual cylinders are withdrawn and injected under the necessary pressure. In an engine having radial cylinders 11, each with a single port for the inlet of air and exhaust, a low-pressure pump operated by the crank shaft is enclosed in a chamber 16, draws its supply from a tank 34 through a conduit 29, and delivers into a conduit 32 leading to a conduit 51 in such manner that the fuel travels always in an upward direction. The fuel injection devices for individual cylinders comprise a cylinder 39 in which a high-pressure pump plunger 40 is reciprocated intermittently from the crank shaft against the pressure of a spring 41 enclosed in a casing 38. Fuel flows from the manifold 51 through an extension 55 and a filter 56 to annular ports 42 which are uncovered by the plunger during its out-stroke. A check valve 43 is located in the duct leading to each injection nozzle. The pump associated with the uppermost cylinder is provided with an extension 65 through which fuel returns to the tank 34.

The shuttle is loosely supported between a concave rotary member, which carries and drives it, and a stationary retaining member supporting it axially; the supporting or bearing surfaces are preferably provided at the circumference of the shuttle and are composed of sound-deadening material. In the machine shown the shuttle is arranged in a vertical plane parallel to the axis of the work-arm 2 of the machine and transverse to the line of feed, and is driven by bevel gearing from the usual shaft 12 in the work-arm. In an alternative form the plane of the shuttle may be parallel to the line of feed. The shuttle body 20, Fig. 4, is formed with a' rib 22 (interrupted to form a loop-taking beak 23), which is supported in a carrier 30, Fig. 7, providing circumferential and axial bearing; it is kept in place in the carrier 30, with axial play corresponding to the thread thickness, and optionally some radial play also, by a fixed retaining member 40, Fig. 2. The bearing parts of one or each of the members 30, 40 are of porous sinter metal or non-metallic material such as plastic; the member 30 may be formed wholly of plastic such as nylon or textile-reinforced bakelite, the retainer being provided with a lining of the same material. Alternatively, the rib of the shuttle, except the beak, may be of such material. The shuttle body 20 has a flange 25 which is of varying depth to control and draw off the bobbin-thread, and which is slotted at 24 to receive the needle and be guided by it, so that the beak 23 will not strike it; it is relieved at 29 to reduce the tension of the bobbin-thread momentarily while the needle-thread is being drawn up between the bobbin-thread and the edge of the hole in the throat-plate. The carrier 30 is cut away at 34 to give space for the needle loop to be formed for engagement by the shuttle beak, and at 35 to facilitate the thread passing the bottom of the shuttle. It has a recess 33 to receive a driving member 26 on the shuttle. The bobbin-case has a cylindrical wall and a base 51, Fig. 2, which is formed with a rotation-preventing projection 59, engaging a recess in the retaining member 40, and is cut away on opposite sides to provide a finger grip.

Title: Improvements in apparatus for delivering gas
IPC: A62B7/14
Filed: 1919-04-03
Abstract: 164,766. White, A. E., (Van Sicklen Co.). April 3, 1919. Respiratory apparatus.-Relates to improvements in the apparatus for supplying oxygen to aviators described in Specification 129,623. The high-pressure and lower-pressure valves are situated one at each side of a common partition having ports. The flexible diaphragms act on levers contained within the chambers and adjustably connected to conical valves. The differential mechanism for controlling the aneroid device so as to yield an increased oxygen supply as the air becomes more rarefied, consists of a flexible lever which becomes successively shortened by abutting against stops projecting at varying distances to its path. This mechanism is compensated for variations of temperature. The apparatus is arranged to deliver gas to either one or two persons and a gauge showing the amount of gas actually passing is graduated to indicate the right quantities according to height. The pressure in the supply bottle is shown by a Bourdon type of gauge having a helical flattened tube. The gas is filtered as it enters the high-pressure valve by a screen formed of alternating screens and washers. The high-pressure valve is shown at 23 and the low-pressure valve at 24. Their diaphragms 61, 61<a> act on levers 72, 72<a> fulcrumed at 69, 69<a> to control conical valves 64, 64<a>. The aneroid member 25 has pins 132, 135 which bear on the stem 74a of the valve 24 and spring lever 137 respectively. The latter is pivoted at the point 138 and is limited in its movement to the right by the head 144. At 140, 141 are adjustable stops against which the spring bears in succession as the air becomes rarefied. Its effective length is thus shortened and its resistance increases. There is a slight separation of the pin 132 from the stem 74a and the valve 24 is so designed that no oxygen is delivered until a predetermined height, such as 3000 ft., is attained. The spring 137 is bimetallic to compensate for changes of temperature. The gauge 22 for showing the flow of gas receives gas from the low-pressure valve and delivers it through a tube 118<a> raised above the flow of the gauge to prevent lodgment of dirt. The gas then passes to one or two branches, as one or two persons are to be supplied with the gas, guarded by cone valves 99 having perforations 101. The diaphragm 115 of the gauge acts upon a rod 128, Fig. 6, which rocks a bent lever 125 to bear upon a pin on the spindle of the pointer 119, which is normally brought to zero by a spring 123. The dial 20 is marked to show the right quantity of gas to be supplied to one and to two men at twenty and thirty thousand feet. The pressure nipple 27 for connecting with the oxygen bottle has a by-pass 41 leading to one end of a helical flattened Bourdon tube 39 of a. gauge 21.
