Title: Improvements in or relating to washing machines
IPC: D06F37/30
Filed: 1933-03-22
Abstract: 398,431. Washing-machines. KRAUSS, F. E., 3, Wildenauer Weg, Schwarzenberg, Saxony, Germany. March 22, 1933, No. 8628. Convention date, March 22, 1932. [Class 138 (ii).] In a washing- machine wherein a receptacle b, Fig. 1, is rotated on a vertical axis within a stationary casing a bv means of a water jet c acting on vanes b<1> secured to the receptacle, the rotation of the receptacle is intermittently interrupted so that the goods being treated alternately climb the side walls of the receptacle due to centrifugal action and then fall again. In a modification the receptacle is stationary and the contents are rotated. The speed of the receptacle may be reduced to zero and in some cases the direction of rotation may be alternately reversed. Two nozzles acting in different directions may be provided and automatically operated by the motor g operating the pump f supplying the jets. In the form shown in Fig. 3 the speed is automatically slowed down by means of a centrifugally-acting brake k pivoted at k<1> to the receptacle and engaging a ring l within the casing. In another form a brake pivoted to the casing may be automatically operated by means of a float controlled by the rising and falling level of the liquid, a perforated plate below the float keeping the clothes &c. out of contact therewith. An annular receptacle may be secured around the perforated upper portion of the clothes receptacle into which liquid rises during the rotation of the machine and from which it is discharged as the machine slows down. In another modification, Fig. 6, a curved plate s may be pivoted at s<1> beneath the stationary cover c<11>. As the liquid rises above the perforated plate v it engages the concave face of the plate and moves the plate against a spring s<11> so that a friction surface t on the free edge of the plate contacts with the inner face of the receptacle b. In Fig. 9 a receptacle of the inverted truncated conical shape shown is intermittently rotated by an electric motor u controlled by an automatic switch u<1>, the shape of the receptacle facilitating the rising of the clothes &c. Ribs b<11> within the receptacle restrain the rotary movement of the clothes &c. when the receptacle is slowed down. In another apparatus the receptacle remains stationary and the goods are given a rotary and alternately climbing and falling motion by means of water jets w, w<1>, Fig. 11, acting alternately.

[Also in Group VI] A chamber S forming an enlarged portion of an air passageway 200, 34 confining an air stream to a predetermined path in a housing H receives air and entrained tobacco leaf components and acts to remove tobacco leaf blade portions from the air stream, air being withdrawn from the chamber S uniformly over a large wall area by dust separators 64 appropriately mounted and operatively connected over the area of one wall of the chamber. As shown, tobacco leaves T pass through a gate valve 12 to a threshing drum 18 and thence, after coaction with stationary combs 20, 21, 23, through a serrated-bar grid 22 on to a conveyer 24 which delivers them into an air duct partly defined by a wall 28 and an adjustable flap 26, where the clean stems fall into a container B and the leaf portions are carried by an air current, caused by a suction fan or fans 80, past a curved surface 30 which in conjunction with a downwardly directed air entry through three adjustable flaps 40 acts to return leaf portions with attached stems to the drum 18 for further threshing. The remaining leaf portions, aided by an air entry through three adjustable flaps 36, pass into the chamber S for delivery through a gate valve 44 to a conveyer C, whilst the dust-laden air passes through a grid 56 and enters banks of cyclone separators 64 detachably arranged over openings 69 in the front wall 70 of a detachable dust separating unit D. Each separator 64 comprises a tangential entry 66, an outlet 72 delivering dust to a chamber 62, and a central tube 76 up which the cleaned air passes into a chamber 60 connected to the fan or fans 80. Supplementary air entry to the chamber S is controllably permitted by a flap 59 operated by a worm and pinion 65, whilst additional dust falling from the grid 56 or through a grid-like wall 46 of the chamber S is delivered by screw conveyers 50, 94 through gate valves 52, 96 to receptacles 54, 98. A similar screw conveyer 86 in the chamber 62 delivers dust through a gate valve 88 to a receptacle 90. Specification 737,165 is referred to.

Abstract: 370,170. Asphalt & c. cauldrons. GOLDNEY, W. G., Fritton Lodge, Monkham's Drive, Woodford Green, Essex. March 21, 1931, No. 8762. [Class 107.] Apparatus for preparing asphalt mastic and the like comprises a heating chamber, means for positively or mechanically conveying a stream of broken mastic through the chamber where it is brought to a substantially molten condition, and a pot adapted to receive the mastic from the chamber and to maintain it in a molten condition. The broken asphalt is fed into a hopper 3 from which it is conveyed by a worm conveyer &c. through a tubular chamber 6. At the end of this chamber the material is discharged down a shoot 7 and is then conveyed by a second worm conveyer 9 through another tubular chamber 8 having an outlet 10 leading to a pot 11. The chamber 6 is heated by means such as an oil-burner arranged in a furnace 25, the hot products of combustion passing over the chamber 6 into a chamber 26 which is partitioned from the furnace by a wall 27 and contains the second tubular chamber 8. The gases pass from the chamber 26 and around the pot 11 to an uptake. An internal-combustion engine 12 is adapted to drive the worm 9 by means of sprocket gear 15, 16, and the worm 8 is driven from the worm 9 by gearing 17, 18. The engine is also adapted to rotate the tubular chamber 8 by sprocket gear 21, 22, and the chamber 6 is rotated at the same speed but in the opposite direction by gearing 23, 24. The relative speed between a conveyer and its chamber is such as to provide a slow passage of the mastic through the chamber. Alternatively, the chambers 6, 8 are stationary and the worms are provided with a faster pitch at the ends than at the parts within the chambers to ensure a quick feed in the material and a slow passage in the chambers. The chambers may be built up of rings riveted or bolted together. The material in the pot may be stirred by a paddle 29 on a shaft 30 which is driven by gearing 32 from the shaft of the worm 4. The pot may be heated by a separate heater. The apparatus may be provided with a crushing mill for breaking the asphalt into pieces prior to feeding to the hopper.

Title: Feeding mechanism in a sewing machine
IPC: D05B3/06
Filed: 1973-02-23
Abstract: 1425185 Sewing machines G TOLLE 23 Feb 1973 [20 March 1972] 8915/73 Heading D1G [Also in Division F2] In a buttonhole sewing machine having the needle bar under the work and the loop taker above it on a pivoting bracket arm, the work clamp 30 (described in Specification No. 8912/ 73) is attached to a threaded shaft 57 which is driven forward and back automatically by a pulley 54 on an internally threaded sleeve 51. The driving belt 70 is indexed either forward or back by a mechanism (Figures 7 and 8) driven by two eccentrics 74, 75 on the main drive shaft 20. When the work clamp reaches the end of its travel in either direction it trips an escapement mechanism which sets in train the reversing of the driving belt 70. A lug 186 on the work clamp depending between the arms 183 strikes one arm 183 and a stop lever 175 is tilted so as to release the feed reversing cam 140 and allow it to rotate through “ turn before engaging the stop lever 175 again. In rotating a lobe 160 on the cam 140 strikes a bell crank lever 136 (Fig. 9) and pushes out whichever end of its is inwards. This causes a link 130 (Figure 9) to partially rotate a sleeve 125 on a shaft 72 and the sleeve is connected by a toggle action (Fig. 5) to the feed frame 97 which reverses the belt indexing mechanism 73. In the indexing mechanism (Figures 7, 8) the angular position of the frame 97 will alter the movement of the bell crank lever 82 through toggle links 95, 95' and so alter the direction which the shoe 89 drives the belt. The feed reversing cam 140 is driven by the worm and wheel, the worm being driven from the main drive shaft 20 via a belt 25 and a friction clutch 201, 203. When the gear wheel is stopped by the stop lever 175 the worm will tend to ride along the gear wheel leftwards until the clutch faces separate. When the gear wheel 142 is next released a spring 205 presses the clutch faces into engagement again.
