WASHING MACHINE.

Application filed December 3, 1920. Serial No. 428,020.

To all whom it may concern:

Be it known that I, CHARLns E. McCoy, citizen of the United States, residing at Logansport, in the county of Cass and State of 6 Indiana, have invented certain new and useful Improvements in Washing Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in pounder type washing machines and the principal object of the invention is to furnish a machine of this type which is of simple inexpensive construction, which will ep- 1 crate efficiently to quickly clean clothes and which may be expeditiously manufactured.

Another object of the invention is to provide a washing machine of this type having a main body formed from a single piece of sheet metal, and to support this body on angle iron legs which form the joints between the cut portions of the'body.

A further object of the invention is to furnish the one-piece body with integral flanges at the upper edges of certain of its walls, which flanges project outwardly and function to support the hinged lid of the body,

Another object of the invention is to furnish an improved basket designed to be arranged in the body and to be resiliently supported so that it may reciprocate vertically when the pounder operates. The springs which support the basket are connected to the basket by means which will not tear or snag the clothes contained in the basket.

A still further object of the invention is to furnish an improved pounder whichmay be manufactured from channel and angle iron and which will operate ,efliciently without liability of tearing the clothing.

A still further object is to provide novel operating means for the pounder which is supported above the machine lid by brackets .45 of improved construction.

Finally it may be stated that the primary object of the invention is to improve the entire construction of pounder type washing machines and to eliminate defects which have been found in these machines in practical use. i

With the foregoing objects outlined, and with other objects in view which will appear as the description proceeds the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawings and more particularly pointed out in the appended claim.

Referring to the drawings Figure 1 is a perspective view of my improved machine.

Fig. 3 is a horizontal longitudinal sectional View taken on line 3+3 of Fig. 2.

Fig. 4 is a plan view of the blank from which the body portion of the machine is cut.

- Fig. 5 is a perspective view of the improved basket.

Fig. 6 is a detail showing the manner in which the coil springs are connected to the bottom of the basket.

Fig. 7 is a perspective view of the pounder.

Fig. 8 is a side view of said poun-der; and

Fig. 9 is an end view of the same.

Fig. 10 is a plan view of the underside of the machine lid showing the reinforcement for said lid. r

Fig. 11 is a side view of one of the pounder operating mechanism supporting brackets.

4 Fig. 12 is a plan view of the basket blank.

Fig. 18 is a perspective view of the crank shaft.

Fig. 14 is a perspective view of the pounder rod guiding bracket.

In the drawings, l'designates the body of the improved machine, which in the present instance is formed from a single piece of suitable material, such as sheet metal and this blank includes a body portion 2 which forms the bottom of the tank when the blank is folded, side wings 3 which form the sides of the tank when the blank is folded, and wings 4 which form the ends of the tank when the blank is folded.

All of the wings are bent upwardly at right angles to the body 2 in order to form a rectangular tank and the corners of this tank are secured by rivets or the like to angle iron legs 5, the latter serving to form the joints between the wings and to reinforce the tank construction. The upper edge of one end of the tank is folded or bent 1 outwardly to provide an integral flange 6 and the upper edges of the sides are likewise bent voutwardly to form similar flanges 7.

It will be noted that the ends of the. flange 6 and one end at each of h fl nges 7 are 110 angularly cut in order to form a continuous flange extending from the rear end of one side to the rear end of the other side of th tank.

These machines are generally used in connection with a wringerand for this reason I have arranged a bracket 8 at one end of the tank in order to support the wrmger. The other end of the tank is'provided with an inclined bracket 9 which serves as a support for the hinged cover 10 when said cover is in raised position. This bracket 9 is provided witha hand hole 10* adapted to re ceive the operators fingers when he desires to move the frame on its supporting casters. When the cover or lid is. closed the flanges 6 and 7 engage the edge portions of the lid and support the same. 7

Located within the tank is my improved basket 11 which is preferably of rectangular shape in horizontal basket is preferably formed of a single sheet of metal and includes imperforate side and end walls and a perforated bottom. The ends of the basket are provided with handles 12. The blank from which the basket is formed includes a perforated body 13, side flaps 14 and end flaps 15. The flaps are bent upwardly at right angles to the body 13 and these upwardly bent flaps form the walls of the basket and are secured together by corner angle irons 15 which are preferably rivetted to the walls.

The perforations in the body or bottom 13 may be stamped out when the basket blank is cut and this will facilitate manufacture of the basket.

The perforated bottom is provided With a plurality of helical coiled springs 16 and the larger or base portion of the-springs are designed to rest on the bottom of the tank 1. These springs are preferably made of brass or other material non-corrodible under the action of water. The upper portion or upper coil of each spring is secured to the bottom of the basket by means of U- bolts 17. Each of these U-bolts passes through a plurality of apertures in the bottom, engages a portion 18 of the bottom and the upper coil 19 of a spring, and a clamp plate 20 is placed on the legs of the U-bolts and is secured in position by means of nuts 21. I preferably employ one of these U- bolts for each spring and as the free ends of the springs are secured they will not project through the basket and snag the clothes. 7 As the curved portion of each U- bolt is arranged in the bottom of the basket,

the clothes will not be torn by the bolts.

Itwill be noted that the hinged cover is provided with an internal reinforcement formed of side bars 22, end bars 23 andfa central cross rail 24, the latter being apertured to receive the pounder rod of the machlne. The upper surface of the cover or cross-section. The 7 lid is provided with a substantially U- shaped main bracket 25 which is apertured at its central portion to permit reciprocation ofthe pounder operating rod 26. The lid is also provided with two parallel brack ets 27 which are formed from strips of sheet metal or molded from cast iron. Each strip is bent intermediate its ends to provide anupper loop 28 and diverging legs 29, the intermediate portions of the latter being secured together in order to provide the loops 28. These loops function as bearings for a shaft 30 which is provided at one end with a flywheel 31 having an operating handle 32. The other end of the shaft'is bent to form a crank 33 which has a shoulder 34 and a reduced portion 35, the latter being apertured to receive the cotter pinor other fastening means 36. A pitman 37 has one of its ends apertured to receive'the reduced portion of the crank, and the pounder rod is provided with a plurality of apertures 38 designed to receive the angular end 39 of the pitman 37. It will be noted-that the depth of the stroke of the pounder rod may be adjusted by shifting theend 39 of the pitman to one or the other of the apertures 38.

From the foregoingit will be seen that rotation of the fiy-wheel and shaft 30 will cause the extension of the crank to revolve, and this rotatable movement will impartvertical reciprocating movement to the pounder rod 26. g V

The pounder per se consists of a plurality of parallel arranged channel-shaped irons 40 the lower edges of which are curled as shown at 41 so that they will n0t-tearor snag the clothing in the clothes containing basket. A strip of wood or the like 40* is arranged in the channel of each of the mem bers 40 and angle irons 42 are arranged above said members 40 and are secured to the members 40 and'40 by means of nuts and bolts 43. While nuts and-bolts are shown in the drawing it will be understood that any other suitable fastening means may be employed. i

The lower end of the operating rod 26 passes through the central one of the members 40 and a nut 44 is threaded onthe lower end ofthe operating rod 26 passes through the central one of the members 40 and a nut 44 is threaded on the lower endof theopcrating rod and functions to retain the pounder in rigid connection with the rod.

When it is desired to use the machine,

the-basket maybe removed and the clothing placed therein; Then the basket is replaced and the lidmay be swung downwardly, and

7 t e-di t. f om the sa e lVhile I have shown and described the preferred embodiment of the invention, 1 am aware that various changes may be made in the construction shown Without departing from the spirit of the invention as expressed in the following claim.

What I claim and desire to secure by Let ters-Patent is:

A Washing machine including a tank, a basket arranged Within said tank and having a perforated bottom, coiled springs arranged between the bottom of the tank and the bottom of the basket, and U-shaped bolts having their curved portions arranged Within the bottom of the basket, the leg portions of said bolts extending through the bottom of the basket and engaging the upper coil of the springs, clamp plates mounted on the legs and fastening means securing said clamp plates on said legs.

Tn testimony whereof I hereunto affix my signature.

CHARLES E. MCCOY.
