WASHING MACHINE.

Application inea April 2,

fo all whom t may concern.' Beit known that I, GEORGE T. BRYAN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Washing Machines, of which the following is a speci- Fieation. l p

My invention relates to a machine for washing and wringing clothes, sheets, etc., and one object is to provide an e'licient machine of this character' in which clothes, etc., may be thoroughly washed and wrung without removing them from the machine, thereby saving the time and labor now required when the washing is done in one machine and the wringing in another.

In carrying out the invention I employ a perforated drum revolubly mounted in a cylindrical casing which is adjusted to on'ey position for the washing operation and another position for the wringing operation, a novel arrangement of gearing being ernployed to drive the perforated drum with an alternating rotary motion during the washing operation and vwith a continuous rotary motion during the wringing operation, as will hereinafter appear, reference being had to the accompanying drawing in which:

' Fig. l is a vertical sectional view 'of the machine on 'line I.I of Fig. 2.

Fig. 2 is a broken end elevation of the machine.

Figs. 3 and 4 are details of bearings employed in carrying out the invention.

In carrying out the invention, I employ v a cylindrical ,casing 2 provided at one end with a lid 4, which is normally held in closed -position by a suitable fastener 6. The casing 2 is provided intermediate its ends with two diametrically-opposed fixedlymounted trunnions 8 journaled in the u per portions of a pair of standards 10 xed upon a base 12.

l14 designates a perforated drum arranged concentrically- Within the casing 2 and nearer one end thereof than' the other to leave a relatively large space 16 for a pun' pose which will hereinafter appear. The drum 14 is. provided at one end with, a lid 18, which is normally held in closed pernin tion by a suitable fastener 20.

The perforated drum 14 is mounted at one end upon a stub shaft 22 and at lts op o- Site end upon a drive shaft 24 journa ed 1923. Serial N0'.'629,365.

in bearings 26 and 28, respectively, fixed to opposite ends of the casing 2. The drive shaft 24 is provided at its outer end with a bevel gear 27 and a small gear 29, said gears being lixedly mounted upon said shaft. lhen the casing 2 and the drum 14 are in the washing' position disclosed by full lines, Fig. l, the gear 29 intermeshes with a segmental ge'ar 30 fixedly mounted upon a stub shaft 32 journaled in the upper end of a standard 34 mounted upon the base 12. The stub shaft 32 is driven from an electric or other suitable motor 34 through a train consisting'of a worm 36, a worm wheel 38, a bevel gear 40 fixed to the worm wheel 38. a bevel gear 42 intermeshingwith the bevel gear 4() and fixedly mounted |upon a shaft 44, a disk 46 mounted upon ythe shaft 44, a connecting rod 48 connected at.its lower endto the disk 46 through awrist pin 50, and a crank 52 pivotally 'connected to the upper end of the connecting rod 48 and fixed upon the shaft 32. The Worm 36 is loosely mounted upolr the motor shaft 54- and hasan integral clutch member 56 for engagement by .a companion clutch member 58 slidably mounted upon the motor shaft 54 and having a grooveand-feather connection 59 therewith, so that itwill ro-` tate with said shaft 54. A lever 62 is' provided for shifting the clutch member` 58 into and out of ber 56 The outer end o'f the drive shaft 24 is held in proper position lo hold the gear 29 in mesh with the segmental gear 30, by means of-a fixed bearing member 64 and a. movable bearing member 66 mounted on a pivot 68 carried by the stando rd 34 and provided with a hand lever 70. whereby it may be. thrown to active or inactive position. rlhe lever 70 is held in either of ils positions by a notched segment 72 fixed to the slandard 84.

When the clutch member 5S is thrown inlo engagement with the clutch member 56, continuous rotary motion is imparted gear with the clutch mem- -by the motor 34a to the disk 46 through the intervening mechanism, while an alternating rotary motion is imparted to the drum 14 through the mlermedlacy of the connect.- lng rod 48- and intervening gearing.

After 'the clothes or other articles wltlnn the drum 14 have been thoroughly washed they may be wrong by adjusting the casing 2 and the dru1n 14 to the vertical position lll() 4:feather connection held in engagement with disclosed by dotted lines, Fi 1. When-in the last-mentioned position a l of the water drains from the drum 14 into the spaoe 16 where it is prevented from around the shaft 24 by the long bearing 28. When in 'the Vertical position as stated, the drum 14C is driven continuouslyA in one direction at relatively high speed to extract the water from the clothes or other articles by centrifugal force. Driving of the drum 14 is effected by tlie bevel gear 27, a bevel gear 7e, a cog wheel 76, and a pinion 78 mounted upon the motor shaft 54. The cog wheel 76 is fixedly mounted upon a. countershaft 80 journaled' in bearings, 82 fixed upon the base 12.

The bevel gear 7 4 has a groove-and 75 with' the shaft 80 and is held iny frietionzl engagement with the gear 27 by a spring 86. A stop 87 is fixed tothe counter-shaft 8() to prevent the spring 86 from pushing the bevel gear 74: too far to the left. The gear 27 is held in engagement with the gear 74: bymeans of a fixed bearingSB and a movable bearing 90, which latter is mounted upon a pivot 92 and controlled by a handle 94 adapted to be held in either of its positions by a. notched segment From the foregoing description itis :ipparent that I haveprovided a machine in which the gear 29 is reliably held in engagement with the segmental gear 30 during the washing operation, and the bevel gear 27 is the gear 7 4 during the wringing operation; and'while I have shown and described the preferred construel tion, combination and arrangement of parts,

leaking out` 4whee I reserve the right to make such changes as properly fall within the spirit and seope of the claim.

Having4 thus described my invention, what I claim and desire to secure by Letters Patent, is:

In a machine of the character described, a oylindriealcasing, trunnions fined to said casing, supports in which said trunnions are mounted so that the easing may be rocked to vertical-'and horizontal positions, a perorated drum mounted in and fockable with the easing, said drum' being proportioned to leave a relatively large space between itsbottom and casing when in vertical. position, a. sha xed to said drum and extending-t through one end of the casing, a gear w eel fixed to said shaft, a segmental gear for imparting an alternaterotary motion to said' gear l7 a. .standard having' a fixed bearing member constituting a stop for the shaft when adjusted to a horizontal position to engage the gear Wheel with said segmental gear, l. Inovable bearing member for holding the shaft m engagement with AsaidL fixed bearing member, mechanism for driving the segmental gear, and gearing ooacting with a portion of said mechanism Jfor drivingV the shaft in one direction when adjusted to vertical position.

In testimony whereof I aiix my signature in the presence of two witnesses.
