Title: Temperature responsive valve
IPC: F16K15/18
Filed: 1972-06-15
Abstract: 1356085 Timing ignition BENDIX CORP 15 June 1972 28106/72 Heading F1B [Also in Division F2] A valve for connection between a carburetter and a distributer vacuum advance cylinder, for delaying spark advance when the engine temperature exceeds 60‹F, has a nipple 9 for connection to the vacuum advance cylinder, a nipple 11 for connection to the carburetter, and a closure disc 23 which is biased by spring 25 on to seat ring 21. The disc is tilted to an open position by bi-metal strip 31 when the engine temperature is below 60‹F, thereby allowing normal advance and retard. Above 60‹F the disc is seated and flow takes place from the cylinder via restriction 29 so that spark advance is delayed sufficiently long for a vehicle to accelerate to 30 m.p.h. In this condition, the disc is readily unseated by reverse flow to allow normal spark retard. The valve serves to reduce omission of nitrogen oxides when a car accelerates at speeds below 30 m.p.h. and its engine temperature exceeds 60‹F. A similar valve may be closed below and opened above a predetermined temperature.

Filed: 1948-11-05
Abstract: 657,074. Motor vehicle transmission gearing. ROTARY HOES, Ltd. Nov. 5, 1948, No. 28760. [Class 79 (ii)] [Also in Group XXIV] A speed reduction gear for a tractor of the type in which drive is transmitted to the road wheel through two aligned splined shafts interconnected by a removable sleeve, comprises two gear wheels mounted on the.ends of the splined shafts in place of the connecting sleeves, one being axially movable by selector means from one position in which the faces of the gears interengage to couple the shafts directly, to another position in which the gears are connected through a layshaft gear to give the desired reduction. Fig. 2 shows the type of tractor to which the invention relates 11 being the rear wall of the gear box and 13 the projecting splined driving shaft, which is normally connected by a removable sleeve 14 to the splined end 15 of the input shaft of the differential. In this type of tractor there is usually a selector shaft 26 for an adjacent clutch 27 for the drive to a hydraulic pump, this arrangement also being modified according to the invention to allow room for the reduction gear. Fig. 3 shows a reduction gear according to the invention applied to the layout of Fig. 2. The connecting sleeve 14 has been removed, and a plate 22 bolted to the rear wall of the gearbox 11, the plate 22 supporting a second parallel plate 21 by bolts and spacing members (not shown). Journalled between the two plates 21, 22 is a layshaft gear 20. Journalled in the plate 21 is a gear 18 which is slidable on the splines of an extension 25 of the splined shaft 15. The position of the gear 18 is controlled by a selector fork 34 connected toa sleeve 37 slidably mounted on a fixed pin 38 mounted on the plate 21. With the sliding gear in the left-hand position shown drive is transmitted from the gear 19 mounted on the splined shaft 13 projecting from the gear box, through layshaft gear 20 the gear 18 and hence shaft 15 to the differential. With the sliding gear 18 moved to the right, the drive through the layshaft is interrupted and dogs in an annular recess on the face of the gear 18 engage the gear 19 to transmit a direct drive. With the arrangement shown in Fig. 3 the reduction gear mechanism would foul the normal selector mechanism 26, Fig. 2, of the clutch for the hydraulic pump drive, accordingly such selector mechanism and its mounting is removed and that shown in Fig. 3 is substituted. As shown, the plate 21 carries a fixed pin 32 on which is slidably mounted a sleeve 31 which carries a cranked selector fork 28a. Specification 560,085 is referred to.

Abstract: 464,440. Coin freed apparatus for delivering strip tickets. SCHNEIDER, R., and WESTINGHOUSE TICKET MACHINE CO., Ltd. Oct. 18, 1935, No. 28869. [Class 27] [Also in Group XIX] In coin-freed automatic machines wherein a ticket is cut by a knife 4 from a strip 3 and delivered through a slot 5, means are provided for obviating trouble arising when the ticket 3a is prevented in any way from being projected through the delivery slot. When the ticket is thus obstructed, a convex support 7 causes the ticket to be bowed and engage the concave underside of a guide member 10, which is consequently moved upwards, carrying with it a lower guide member 9 against the action of a spring 17. Pivoted levers 12, 11 connected by a link 15 carry the members 9, 10, the link 12 being shorter than the link 11 so that the members 9, 10 are caused to approach one another during their upward movement to form a thin curved channel preserving the shape of the ticket. When the slot 5 is free again, the spring 17 restores the parts 9, 10 and the ticket is projected from the slot. Coin-slit closing-devices-To prevent further operation of the machine when the parts 9, 10 have been moved to the upper position, one of these parts may operate contacts included in the energizing circuit of an electrically actuated device controlling the closure of the coin insertion slot.

Title: Improvements in or relating to an impact clutch for portable power-operated impact wrenches and like tools
IPC: B25B21/02
Filed: 1947-10-29
Abstract: 659,738. Screwing-up and unscrewing nuts &c. INDEPENDENT PNEUMATIC TOOL CO. Oct. 29, 1947, No. 28881. Convention date, Feb. 16, 1946. [Class 83 (iii)] A portable power-operated impact-wrench comprises relatively-rotatable hammer and anvil members 30, 16 housed in a casing 13, clutch-elements 32, 32a interposed between said members to clutch and declutch them to impart rotational hammer blows on the anvil during relative rotation of the two members, and means for controlling the action of the clutch-elements to once in each rotative cycle of the hammer member. The rotor 4 of a compressed-air motor, which is capable of operation in either direction under the control of a valve 11, drives a shaft 27 on which the hammer 30 is journalled between flanges 25, 26. The hammer 30 is disposed inside the anvil member 16 which is in the form of a hollow cylinder with a depending spindle 15. The elements 32, 32a are mounted slidably in a slot 31 in the hammer 30 and retained therein by pins 33 passing through radial slots 34 in the hammer 30 and arcuate slots 35 in the flanges 25, 26; if desired, the pins 33 may be located in cushioning bushes in the elements 32, 32a. Projections 36 forming the actual impact surfaces are provided on the elements 32, 32a and are adapted to engage slots 20, 20a of corresponding depth in the wall of the anvil 16. The slots 20, 20a and projections 36 are offset relatively in the axial direction and to the same extent so that each projection can engage only in its corresponding slot. In operation, the hammer 30 is driven through the pins 33 and slots 35, and the elements 32, 32a are urged outwardly by centrifugal force until the projections 36 thereon engage their corresponding slots 20, 20a. Upon the anvil encountering excessive resistance to rotation, rotation of the hammer 30 relatively to the anvil 16 is caused by the slots 35 acting to withdraw the elements 32, 32a which remain in the retracted position until the projections 36 can again enter their respective slots 20, 20a. The Specification as open to inspection under Sect. 91 comprises also a reference to the construction of the hammer and anvil members so as to permit of the striking of more than one blow per revolution of the hammer. This subject-matter does not appear in the Specification as accepted.
