.application filed dimly 53, wie. lterial No. Mae@ To iE/wrmt t may concern:

Be it known that We, Financia Herzen and Jenna Annan, citizens oi the United States, residing at huehlo, in the county of Pueblo and State of Coiorado, have 1nvented a certain new and useful improvement in Washingdlytachinee, of which the oliowing is a full, clear, and exact description.

@ar invention is an improvement in waehinpg machines and its principal object is:A the provision of a simple, compact machine having the fewest poetible number of parte; and. one which shall he capable of being opened for charging or removing the clothes without the' neeeee'ity of lifting or erung'n ing the mechanism carrying mp. I v

Another object oi.2` our invention Is to so l the maci'iine that -wriun ine;v means gf can readiiy be added and. operated by the power meane provided tor driving the waehin machine.

nrther and more detailed objecte and advantages of oar invention will .later appear in the epeciir'icatiraru I lin thev single Sheet ci drawings accompany/ing this application and forming a part ereor Figure 1 is' a side view of the entire machine', a portion of the eide oi' the tub Yheine-g broken away to dieclose the interior portions: 'of the device; Fig. 2 1s a: perspecf tive, viewed; from the right hand' side of Fi 1, of the plungeroperating mechanism an the power connections thereto, a prtion out the supporting braclet for the plunger rod being broken away; Fig. 3 is a perspective of the guide plate which is immediately en top ofthe coveryand Fig. 4 is a perspective of the reciprocating sleeve which serves to impart vertical' in tion to the plunger rod. l

Referring to the drawings, in which like numerals of reference indicate likeparts in all the figures, 5 ie the frame of the machine and 6 the tub which may he of any desired' shape and which we have shown as being of a rectangular form.

7 indicates a plunger adapted to be reciprocated up and down in the tub and to thoroughly subject the clothes to the action oi' the sudo and. water. The plunger actuating mechanism is mounted on the cover, which cover is mounted to slide on ways 'in the upper side members 9 of the frame 5,

ri`he actuating' mechanism comprises a .crank shaft 10, journaled in a bracket l1 and having a crank l2 at one end thereof. rlhe crank 12 is connected by a. link 13 with the reciprocating skeleton sleeve 14. (See Fig. 4) which encirclesthe plunger rod 15,.

Between the upper and lower rings 16, 17, respectively, of the skeletonsleeve 14 there is received a cam grooved sleeve 18 which is rigidly attached to the plunger rod by rivets 19. The sleeve 18 is formed with a spiral cam groove 20 in which is adapted to travel a roller 21 carried by a bracket 22 on the guide plate 23. This guide plate 23 has a circular opening 40 (see Fig.

3) for the passage of the sleeve 18 and a notch 41 for the vertical member of the skeleton sleeve 14:, thus preventing the latter from turning but permitting the sleeve 18 to freely turn. The plunger rod 15, which is hollow and provided with an air escape valve 24 in its top, is further guided nea-r the top by the tl bracket 25 through which it passes. j

The crank shaft 10 is slotted near its outer end and the drive shaft Qis also slotted on its adjacent end. A sliding sleeve 27 carries key on its inner face adapted to enter the slots in the shafts t0 and 26 and forms a means of uniting these shafts; and a set screw 28 may, if desired, be provided in the sleeve 27 to hold it rmly in position. The power shaft 26 is driven by a sprocket chain 29 running over a sprocket wheel 30. The

sprocket chain 29 receives its power through suitable speed reducing means from a motor 31", which may be of any enitable kind..V

ln order that the body of the tulo 6 may be of suilicientlysmal'l dimensions so that all the clothes therein will be subjected to the action of the plunger and at the same time to permit of easy access to the interior of the tub, We'have provided an extension or bay 33 formed hsa part of the tub, which bay ie adapted to receive'substantially half they plunger when the cover is pulled back to'open the tub. hile we have shown the frame as considerably larger than Ythe tuh and have shown the power means as mounted on this extended part of the frame, this was done for the pnurpose of preventing confusion in the drawings; and it will be evident that the frame need not be larger than the dimensions of the tub and that a frame of that size will carry the power means as well as `one of the relative proportions illustrated.

A section 34 of the cover opposite the bay side of the tub is hinged to the remainder 'of the cover as shown in Fig. l; this swingingA section alords e convenient means of inspecting-the clothes without the .necessity of opening the entire 'cover and also permits of the substantially :full opening of the tub when the cover has been retracted as for as `the hay 3E/will permit. lWe also prefer to provide the power shaft 2 6 with a small pulley '35 for e purpose" later to be de scribed. i

Operation: Assuming that the cover is drawnback, the tub.is charged with the clothes to be Washed and the cover is pulled into the position shown in Fig. 1. @ne or other of the shafts v10, 26, is then turned by hand until the slots are opposite and the sleeve 27 is slipped to the position of Fig. 2 and set in position by the screw 28. The motor 31 then being started motion is coininunicated to the crank shaft i2 and, through the medium of the link 13, vertical reciprocatory motion is transmitted to the skeleton sleeve 14. Inasmuch as the skeleton sleeve sti'addles the sleeve 18 on the Aplunger rod, the latter will be moved up and down end, by means of the roller 2l runningin the spiral groove 20, the plunger rod 15 will ut the saine time vbe turned inthe direction of' s right screw when going down sind in the opposite direction when coming up. Theclothes will thus be subjected not only to an up and down motion `but .also Vwill be swirled back and forth through the water and suds, thus materially aiding in the cleansing operation. When the washing is done the sleeve 27 may be slipped buck to allow the shafts to break and the cover 8 may be pulled'back to almost clear the full -dimensions of the tub.

lf it is desired fi wringer may be mounted. in any convenient place on the machine frame and' may be driven by :i belt or sprocket chain running on. the wheel 35; thus the saine motor may be utilized to run both the washing machine and the wringer, which is a great convenience. f

Having thus described our invention, what we claim and desire to secure by Let ters Patent is:

msoeei l'. In @washing machine, :i tub, :i hori- -zontslly 'sliding cover therefor, und :i pluii slides to open seid tub with :i hay for receiving :i poltion of said plunger.
