Abstract
107,637. Ascoli, L. D. July 4, 1916. Vacuum cleaning-apparatus; valves, arrangement of. - In a vacuum cleaner of the singleacting type, the dust-separating bag is tapered and is disposed in or on a spiral spring frame so that it will pulsate or collapse and distend owing to the intermittent suction, and dust will be prevented from adhering to the surface; more than one such bag may be used in series or one within the other, or one or more pulsating bags may be used with one or more bags mounted on rigid frames. The vacuum cleaner shown in Fig. 1 comprises a pump cylinder f, a tapered dust receptacle a, and a suction nozzle b, suitably secured together in an air-tight manner. A tube c may extend inwards from the nozzle and be provided with a dust-deflecting plate d. The dust bag q is supported internally or externally on a spiral spring r, the largest convolution of which is covered by the edge of the bag and is secured by a flanged ring u screwed on to a cylindrical separator casing i, with or without a disk v of wire-gauze, fabric, &c. The upper end of the casing i has one or more holes k adapted' to be intermittently closed by a disk valve l of leather &c. loosely mounted within a perforated cage m. The valve aperture may be covered with wire-gauze, fabric. &c. o. The end of the bag q may have a deflecting-disk q<6> of leather or metal. There may be a second bag on a collapsible frame within the bag q, an outer bag on a rigid frame may surround a bag within a collapsible frame, or a double bag may be mounted in or on the collapsible frame, the bags being stitched together and to the frame at intervals. The convolutions of the spring or other frame may be covered with wool, felt, cotton, muslin, &c. to prevent wear of the fabric of the bag, and the spring frame may be stitched to the disk v. A ring w of leather, india-rubber, &c. forms a tight joint between the casing i and the cylinder f. The pump piston p and its cup-leather y are secured to the piston-rod x by a flanged sleeve z, a short rod 1 passing through holes in the sleeve and the rod x, and a screw 2 passing through a washer 3, an axial hole in the rod x, and a screwed hole in the rod 1, which serves also as a stop to limit the relative movement of the piston and the cylinder. Air holes 4 are provided, and the rod x passes through a plug f<1> with a hollow handle f<2> and terminates in a handle p<1>. In use, the cylinder is reciprocated by means of the handle f<2> on the rod x which is held stationary. In a modified form of cleaner, the separator casing 16, Fig. 6, is soldered on to the pump cylinder 28, and the tapered dust receptacle 10 is screwed on to the casing 16 and its end abuts on a washer 7 in a sleeve 8 on the cylinder 28. Two bags 23, 25 on spring frames are provided, the bag 25 being either free to pulsate, as shown, or slightly compressed between a gauze disk, covering the valve aperture in the end of the casing 16 and a disk 21 to which the bag 23 is secured by a screw cap 24. A wire frame 26, 27 surrounds the bag 25 within the casing 16. The disk 21 has gauzecovered apertures 22 out of alinement with the valve aperture. A flange 31 covers the air holes 30, a rotatable celluloid or like handle 35 is provided, and washers 11, 38 absorb shock in working. The suction nozzle b, Fig. 1<a>, may have on its rear edge shallow intersecting grooves 9 to aid in picking up pieces of cotton &c.
