Filed: 1945-03-07
Abstract: 608,448. Sanitary closets; bed-pans. FAULKNER, A. W. March 7, 1945, No. 5721. [Class 26] [Also in Group XXXII] An apparatus for removing excrement from bed-pans comprises a bed-pan 5 having fine flushing orifices 19 distributed around its upper part and a soil outlet 23 at the bottom, a closed excrement collecting vessel 8 communicating with said soil outlet through a flexible soil pipe 7, a liquid reservoir 17, liquid delivery means such as a blower or air pump 15 connected to said reservoir and communicating through a flexible tube 18 with the flushing orifices 19, and suction means, such as an exhaust fan 11 connected to the upper part of the collecting vessel 8 to withdraw air thereform so producing suction in the soil pipe and transferring excrement from the bed-pan to the vessel 8. The air withdrawn may be passed through an air purifier 9 containing deodorising liquid; the electric motor 12 may drive both fan 11 and blower 15, and may be controlled by a switch 21 or by switch 22 manipulated by the patient himself, whilst a plurality of bed-pans may be connected through their soil pipes to a common suction device. The apparatus may be arranged as a transportable unit (see Fig. 1) with a receptacle 6 for the bed-pan when not in use. In operation, on starting the motor 12 by closing switch 21 or 22, suction set up by the fan 11 exhausts excrement from the bed-pan along the soil pipe and into the collecting vessel 8; at the same time the pressure set up by the blower 15 forces water from the reservoir 17 along pipe 18 and through orifices 19 to flush the pan and so return by suction to the collecting vessel 8. Means are provided at 28 for filling the ieservoir 17. at 26 for hot liquid for cleansing the vessel 8, and at 24 for draining off foul liquid, whilst a false bottom 25 is arranged above the opening 24 to retain solid matter and may be removed through the top of the vessel on lifting off the purifier chamber 9.

Abstract: 789,045. Change-speed gearing. ROCKWELL MANUFACTURING CO. Feb. 27, 1956 [Feb. 28, 1955], No. 6023/56. Class 80 (2). Change-speed gearing comprises a gear 60 and a belt pulley 50 loose but axially positioned on an output shaft 32, the pulley 50 being clutchable to the shaft by a slidable claw clutch member 40 while the gear 60 is connected to the shaft by a one-way clutch 76. The pulley 50 is driven by a belt 114 from a pulley 112a on an input shaft 18, while the gear 60 is driven through reducing gearing 100, 102, 106 by a shaft 92 which in turn is driven from the shaft 18 by a belt 116 between stepped pulley sheaves 110, 112. Thus, as applied to a band sawing machine, the band may be driven at high speed through the belt 114 for wood sawing by engaging the clutch 40, or, with the clutch disengaged, may be driven at any one of a number of lower speeds through the belt 116 and the reducing gearing for metal sawing. The number of these lower speeds may be increased by interchanging the pulleys 110, 112. As shown, the left-hand pulley of the multiple-sheave 112 forms the driving pulley 112a for the belt 114, but this belt may be removed to provide an additional lower speed, so that the arrangement shown provides for one wood-sawing speed and seven metal-sawing speeds.
