MOTOR DRIVEN LINEN POUNDER Filed Aug. 30," 1954 Patented July 7, 1936 UNITED STATES PATENT OFFICE Application August 30, 1934, Serial No. 742,156 In Germany January 9, 1933 1 Claim.
This invention relates to a linen pounder with bell operated by an electric motor. Linen pounders and washing devices with an inner bell actuated by an electric motor are known. As compared with these arrangements the casing enclosing the motor and gearing in the linen pounder according to the invention is mounted on a tube, the lower end of which carries the outer bell, the tube serving as guide for the lifting rod for moving the inner bell which, in known manner, is open at the top and provided with a perforated bottom. By this novel arrangement the linen pounder is considerably simplified as compared with the known articles of this type, because the tube serves at the same time as a handle for the operator, as carrier of the motor with the gearing and as guide for the lifting rod of the inner bell. The outer bell may be moved instead of the inner bell or a rubber diaphragm may be employed instead of the inner bell.
Two embodiments of the invention are illustrated by way of example in the accompanying drawing in which:-
Fig. 1 shows in longitudinal section a linen pounder with movable inner bell.
Fig. 2 shows in longitudinal section the lower portion of a linen pounder in which a rubber diaphragm is employed instead of an inner bell.
An outer bell 2 is fixed on the lower end of a tube serving as handle. An inner bell 3 is provided at its lower end (Fig. 1) with a perforated bottom. In the construction illustrated in Fig. 1 the inner bell is fixed on a lifting rod 5 which is guided in the tube l by piston-like guide elements 6.
The inner bell (Fig. 1) is driven by an electric motor 1 which is accommodated in a; hood 8 made of insulating material and attached to the upper end of the tube I. A worm 9 driven by the motor 1 meshes with a worm wheel l0 carrying a crank H hingedly connected by a con- 10 In the modified form of construction illustrated in Fig. 2 the inner bell consists of a capshaped rubber bell or diaphragm 3, the annular outer edge 3a of which engages in a groove formed by an outwardly projecting bead 2' in 15 which it is securely held by a spring ring It. The rubber diaphragm 3' is held at the middle between two metal discs ll connected by screws l8. The lifting rod 5 extends through the two discs and the diaphragm and is connected to the 20 discs ll so that during the reciprocating movement of the lifting rod the discs I! and the rubber diaphragm 3' are moved up and down.
I claim:--
A linen pounder, comprising in combination a 2 tube, a casing on the upper end of said tube, an electric motor accommodated in said casing, an outer bell on the lower end of said tube, a lifting rod vertically guided in said tube, a gearing in said casing driven by said motor and connected 30 with the upper end of said rod adapted to impart a vertical reciprocating movement to said rod, a cup-shaped rubber diaphragm in said outer bell, means for connecting the middle of said diaphragm with the lower end of said lifting rod, 35
an outwardly projecting head on said outer bell forming an annular groove in said outer bell, an edge on said diaphragm engaging in said annular groove, and a spring ring clamping said edge in said groove.
