OTTO G. PFEFFER, OF SALT LAKE CITY, UTAH, .ASSIGNOR T0 UTAHN'A DEVELOYMNT COMPANY, or SALT LAKE CITY, UTAH, A CORPORATION OF UTAH.`

WRINGER-GEARING FOR WASHING-MACHINES.

Application o (117 411710171, it muy] conce-rn Be it known that l. O'r'ro Pi-'i-i|iir.n.y a t citizen of the United States. and residiniri at Salt Lake City; in the eouutv ot' Salt lialre and State ot Utah.l have invented eertain new and useful Improvements in VVringer-Gearing for 'ashingrMat-hines, otn which the following' is a specification.

This invention relates to drivingr Igearing'. and more particularly to wringer driving gearing for washingv machines.

ln operating a wringer by powei` it is dedrive the wringer in opposite di-J so that it' the wringer should bereversed to permitv the clothes to be taken out. ln view of the fact that wringers are operated by inexperienced operators, the mechanism must be simple in its construction and operation, and the controlling mechanism should be so arranged as to be easily manipulated.,

One of the objects of this invention therefore iste construct a gearing in which the driven member, for instance the wringer shaft, can be driven reetion s at will in either direction, and in which this mechanism will consist of few parts so as to be simple in its construction and operation.

Another object. is to provide manual controlling means for the gearing whereby the driven member may be controlled at will. and to construct this controlling' means so as to be susceptible of operation by unskilled operators.

Further objects will appear from the detail description taken in connection with the accompanying drawings in which:

Figure l is a section on the line ll Fig. 2, and Fig. 2 is a section on the line .Of-2 Fig. l.

Referring to the accompanying drawings, 10 designates a washing machine easing.l and 11 a drum arranged to rotate therein in reverse directions and arranged to receive Speeicatlon of Letters Patent. filed December 2?, 1911. Serial No. 668.l86. Renewed May 2. 1913. y Serial No. 765,133.

`rod, one between the clothes to be Washed. The washing machine construction is fully shown and ldescribed in my application Serial No. 668,184 tiled of even date herewith.- The easing body is supported in a pair of end frames one of which is shown `at l2. 'lhese end tramesI are preferably malleable castings, while the casing body is of sheet metal. The end frame 12 has secured thereto or cast integral therewith a series of bearing lugs two of whichare shown at 13 and llt. A bracket l lateiit ed Dee. 30, l 913.

lo is bolted to the. lugs and forms caps for the bearing lugs. A main drive shalt 17 is mounted in the bearingr lugs and has mounted thereon a ,gear '1S meshing with a pinion on a motor shaft (not shown). rl`he shat't 17 formsI the main drive. shaft for driving a" reversing' mechanism l'or the drum' 1l. and foi' driving lthe wriueer as hereinafter described. ".llie reversing: mechanism and its relation with respect. to the wringer driving: mechanism is fully shown and described in my application Serial No; (368,185 filed ot' even date herewith.

The wringer is generally designated by 60, and (il designates the wringer shaft. This shaft. has mounted thereon a bevel gear GQ meshing with a bevel zgear 63 on a cross shaft 64 mounted in bearingv lugs 65 and 6G on thc end frame l2. A bevel gear 67 is mounted on the lower end of the shaft (i4 and meshes with two bevel gears GS loosely mounted upon the drive slial't 67. A vjaw clutch member or sleeve 69 is s )lined upon the drive shaft 1T and is provide( jaws arranged jaws upon the bevel gears G8. AV clutch fork 70 is loosely mounted upon a shaft or rod 7l slidingly mounted in bearings in the

lugs

13 and 14. 4This rod has rigidly mounted thereon tivo collars 72 and 7f3-respectively. and springs 74 and 75 are mounted Yupon thisl collar 72 and the fork, and the lother between the collar 73 and the fork. A vertical shaft 76 having an operating handle 77 is mounted 'loi' rotation in bearing lugs 78 and 79 toi-ined on the end frame l2. A disk 80 is mounted upon and. connected to the lower end oi the shalt 7G' and is provided with a crank pin 8l connected -by a pilman vorflink S2 with the col- ,lar 72. The. disk' is provit'le'd with ay series olE recesses S3 adapted to be engaged by aspring` latch 94 mounted upon the frame l2.

The connection of the drive shaft with either ot the gears GQ will cause the drive. shaft, to rotate the ivi-inner shaft in` reverse directions. The controlling vmeans. described above, vfor 'causing such a connection ot the gears, is so const ruet'ed that the wringer shaft may be driven in one or another direction at the will ot the operatoix ln the drawings. the mechanism is shown in neutral position at which time/both gears 68 are loose on the shaft. li tlie'hanwith to engage with cot'iperating.

end

dle 77 and the shaft 76 are now rotated through a quarter of a revolution in one direction the wringer shaft will be driven in one direction, while if the handle and the shaft are tur'ned from neutral position in`the opposite direction, the direction of rotation of the wringer shaft will be reversed.

It will be noted that the controlling mechanism has two neutral positions, namely one in which the crank pin 8l is in the position shown in Fig, 2, and another position in which the crank pin will be diametrically opposite. The shaft 76 can however be turned from either neutral position in any desired' direction to cause the wringer shaft to be driven in any desired direction. will also be noted that when the shaft is in either of its clutch engaging positions, the clutch canY be thrown to n'eutral position by turning the shaft in either direction. This construction is of great advantagel in washing '.machines, which are operated by unskilled operators, and in` which the operator is liable to become excited (when the clothes are tangled or caught) and forget in which way the handle should be turned to throw out the wringer shaft. With this construction however the operator is not required to remember this. lsince the shaft handle can be moved in either direction to neutral position. The latch 84 will hold the shaf in any of its adjusted positions.

The handle 77 can be moved to its limit to throw in the clutch irrespective of the 35 posit-ion of the clutch member. This is due to the fact th'at the connection between the handle and the clutch member 69 is a yielding one (through the springs 74 and 75). Thus if the handle 77 is operated to throw the clutch member 69 in while the shaft 17 is stationary and While the jaws ofthe clutch member are opposite the coperaling jaws on the bevel gears, the clutch member '69 will be moved until the jaws thereon eni5- gage the jaws on the bevel gear and further lnovement of the handle Will serve to compress one of the springs 74 or 75. As soon as the shaft 17 starts to revolve, or revolve sufficiently to aline the jaws on the clutch 0 'member with' the recesses on the bevel gear, the parts will snap together under the action of the compressed'spring. y.

It is obvious that various changes may be made in the details of construction wit-houtdepartingfrom this invention, and it is therefore to be understood that this invention is not to be limited to the specific construction shown and described.
