GEARING.

To all whom it may concern: g

Be it known that I, J OHN D. A. JOHNSON, a citizen of the United States, residinrr at Omaha, in the county of Douglas and tate of Nebraska, have invented certain new and useful Improvements in Gearing, of which the following is a specification. v

My invention relates to washing machines and the object thereof is primarily to provide a simple and eflicient construction and arrangement of driving and reversing mechanism for the wringer, which mechanism is adapted to be driven by the driving connections for the agitator .of the washing machine.

Various features of advantage and utility in my construction will be apparent from.

the description hereinafter given.

In the drawings, Figure 1 is a side elevation of my complete washing machine; Fig. 2 a sectional elevation on the line 2 -2'of Fig. 3; Fig. 3 a plan view of the machine;

Fig. 4 a cross section on the line 4-4 of Fig.

3 and Fig. 5 Fig. 3.

For the purpose of a clear and definite disclosure of my invention I have herein shown and will hereinafter describe a machine representing one embodiment of my invention although it will be understood that changes may be made, partic-ularly'as to details, without departing from the spirit and scope of my invention and claims.

Referring to the machine herein shown a section on the line 5-5 of the washing machine comprises a washing receptacle 1 supported on legs 1 and containing any usual form of agitator (not shown) such as for instance that illustrated in Howe Patent No. 711,317 dated October 14, 1902, which also illustrates thesame general character of driving connections forthe agitator and as to which I make no claim herein. These driving connections consist of a reciprocating rack bar 2 adapted to mesh with the pinion 3 which issecured to the vertical shaft 4: of the agitator. This rack is pivotally connected at the point 2 with a crank arm or pitman 5 which is pivoted at its outer end to a bevel gear 6, which has two sets of gear teeth oneset 6t and another set 6 the former of which meshes with a pinion 7 formed in the present instance as an integral part of a wheel or pulley 8. This pulley is secured to a horizontal shaft 9 which is journaled in a bracket 10 Specification of Letters Patent.

mounted on the top of the washing receptacle. Thispulley is operated by a suitable prime moverwhich in the present instance is an electric motor 11 whose armature shaft has a small pulley 12 operatively connected with the pulley 8 by means of the belt 13. The gear wheel 6 is secured to a vertical shaft 14 which is journaled in the bracket 10 and which by preference and as shown is extended downwardly a comparatively considerable distance for a purpose hereinafter explained, the lower end being held in place by a bearing 15..

Upon the top surface of the washing receptacle I provide a support or platform 16 which is adapted-to support any suitable wringer such as that illustrated at 17 and the reversible driving connection or clutch mechanism therefor and also the electric motor hereinbeforejreferred to. As shown this support overhangs or projects beyond the sides of' the receptacle thereby providing aplace of attachment for the electric motor which depends therefrom as clearly shown in Fig. 1, the motor and the reversible clutch being in the same vertical plane,

one above the support and the other below.

The clutch consists, oftwo bevel gears18 and 19 connected together by a central portion 20 which in the present instance is. integral therewith. The hub portion of the gear 19 has an angular socket 19 adapted to receive the angular head 21 of a shaft 21 for driving the wringer. These bevel gears are journaled within a housing which isv divided centrally into two parts 22 and 23, the former of which is mounted upon and secured by means of its foot pieces or bracket .22 to an extension 10 of the bracket 10 which is itself secured to the support 16, the two sections or halves of the housing being clamped together by means of the screw bolts 245. By preference the foot pieces are adjustably secured to said bracket extension by the usual bolt and slot connection indicated at 22. Within the housing andbetween the two bevel gears is arranged a clutchconnector which is in the form of. a bevel pinion 25 secured to the inclined shaft 26 which is adapted to be shifted or oscillated in order that the bevel pinion may mesh with the one or the other of the two gears 18 and 19 or may be left in intermediate or neutral position out of engagement with either of these gears. This shaft 26 has, in the present instance, a bearing ..bracket 27 which is pivoted upon the depending shaft 1% of the gear wheel 6, withthe result that said shaft is pivotedin the line of the axis ofrotation of the wheel 6.

lntermediate its length this shaft 26 is providedwith a pinion 28 which mesheswith central. portion of the clutchdevice.

'mnnicated to the shaft 26 and to its pinion 25.

i the bevel teeth 6 on the gear wheel 6, whereby the motion of" the-latter wheel is com- A hand-operated clutch'shifter" is rovided for-the shaft 26, the same consisting lower or inner end of this shifter is formed as asocket 29 to fit Ii-POIrthB onterend of fro the shaft 26- above its pinion 25. In order to hold thi'sshifter' in proper operative position and to prevent its being removed from itsengageinent from the'sha-ft'26, I- provide thenpp'er surface thereof, intermediate its length, with a lug 29- which is adapted to cooperate withthe upper inner edge of the slot 36 in the hon-sing, rig. 21 For the purpose of holding the shifter in either one of 1 its three positions I provide the same with a "springoperated latch 31 pivoted theretoand having a forwardly projecting finger 3-1 .Ijad'ap't'ed to enter any one of the holes 82 in:

the housing-accordirrg to the particular adjustment of shifter. It will be understood that it is notessential that the shaft 14 be entended'down wardly to form a pivot for the inner end of the shaft 26 or that suchj a "shaft be pivoted below the gear wheel-=6, the I only'essential feature in this regard being that theshaft be pivoted in the line of the airisof rotation of the wheel 6 so that in i the different shifted positions of the shaft there shall be no clamping or binding between the gear wheel 6 and the pinion 28. When theparts'are the relative'position shownin Fig. 3which isa neutral position I of the shifter and pinion 25 the washing machine proper only will be operated and thefwrin ger will not be operated. However when-the shifter-is moved to one of the lateralholes 82"so as to bring the pinion 25 into mesh with one of the gears 18 and 19-,

the'wringer wili'be operated in one directionandif the shifter is moved to the other extreme position the pinion 25 -will be brought into mesh with the other bevel gear so as torot'atethe wring'er inthe opposite direction, it being understood that the in- I, lon 28 is always in mesh with the gear wheel 6 is always rotated in the same direc tion. The construction and arrangement of parts above described constitutes avery siinpie bnteifectivemech-anlsnr for the objects in view and a mechanism whichis moreover comparatively inexpensive and economical consequently of manufacture which are important considerations in machines of this character.
