CORPORATION OF IOWA.
GEARING.
Specification of Letters Patent.
Patented J an. 4, 1916.
Application filed September 6, 1912. Serial No. 718,884.
To all whom it may concern Be it known that I, HOWARD F. SNYDER, a citizen of the United .States, residing at Newton, county of Jasper, State of Iowa, have invented new and useful Improvements in Gearing, of which the following is a specification.
It is the object of the present invention to provide a gearing or gear mechanism particularly adapted for use in connection with washing machines.
More particularly it is the object to provide a gearing compact and rugged in construction and simple in character whereby the agitator of a washing machine may be driven and whereby a wringer may be operated, suitable control mechanism being provided for governing the movement of the agitator and, of the wringer when the gearing is driven from a power source such an engine or motor.
The details of the present invention together with the special objects and advantages thereof will be made clear by the following detailed description which is to be taken in conjunction with the accompanying drawings wherein- Figure l is a front view of a washing machine provided with gearing of the pres ent invention. Fig. 2 is a side view of the same machine with the cover partially raised, the covering for the wringer gears having been removed to expose the gears.
35 Fig. 3 is a detail of the wringer gearing and Fig. 4 is a plan view, partly in section, of the mechanism under the tub.
In the embodiment illumated, a tub 1 carried on legs 2 is provided with a rigid ear frame of the construction illustrated in ig. 4. The gear frame 3 is a rigid compact castng provided with ears 4 and 5 through which bolts may be passed for supporting the frame from two of the tub legs and independent of the tub. Much of the gearing for the washer is supported and carried by this rigid frame 3.
The ower shaft 6 is mounted lengthwise of the rame and carries at its outer end a bevel ar 7 meshing with a smaller gear 8 carried on a transverse shaft 9 whereon a drive pulley 10 is mounted. The geared relation between shafts 9 and 6 not only give a desirable speed reduction between the pulley and the power shaft but also places the pulley in advantageous position low down at the side of the structure where it 13 out of the way and where there is little danger of tipping the machine through improper action of the drive belt. The power shaft 6 also carries beveled gears 11 and 12 mounted loosely thereon and having their inner faces shaped to form engaging lugs for cooperatingwith a sliding clutch member 13 keyed to the shaft and hiring an annular groove engaging with the forked arm lat of a bell crank lever pivoted at 15 and actuated by a link member 16 which extends across below the tub to it crank 17 (Fig. 1) provided at the end of a vertically positioned rock shaft 18 which extends up along the side of the tub through suitable bearings and carries a hand grip 19 capable of swinging around into contact with the metal plate 20 carried by the cover of the tub, thereby to serve as a latch orlock for the cover. With the handle 19 in lock engagement with the cover plate 20 the sliding clutch member 13 will be in driving ongagement either with the beveled gear 11 or with the beveled gear 12 depending upon whether the crank 17 has been rocked outward or inward by the twisting movement given to the handle 19.
The gear frame carries a counter-shaft 21 having a large beveled gear 22 meshing continuously with the beveled gears 11 and 12 so that when the clutch member 13 is thrown completely in either direction, power will be transmitted from the power shaft 6 to the counter-shaft 21, the direction of rota tion of the shaft 21 depending upon the direction in which the clutch member 1.3 was shifted by manipulation of the handle 19. The outer or exposed end of the counter shaft 21 carries a rigidly mounted crank disk 23, carrying on its inner face a beveled gear .34, and carrying on its outer face a crank as provided with a bolt hole for more secure attaclmient of a suitable pitman.
The pitman 26 through which power is delivered from the crank disk 23 is connected with the disk through a suitable cast head 27 and is provided at its upper end with a double clevis 28 attachedto a mas sive bell crank 29 pivotally mounted at 30 to a suitable casting secured to the side of the tub, this casting preferably overlapping the stationary portion of the tub top at 31 to afford greater security of attachment. The other arm of the bell crank is pivotally n as mummi 5m!- suppm-ted i Lu it is an hn'gmrtzmt manna-mt that; Hm bell fun 21211 1mm Mwkwmwl 12502;: he gui t: rm and En mesh \xiih Hm duii pinion. when thv mgwm' (f the mzurhin? w in no ipvnwl.

I am aware that various features of the construction here disclosed may be changed and that modifications in detail and in grouping may be effected without departing,
from the spirit of my invention as defined by the appended claims.
\Vhat I claim as new and desire to secure by Letters Patent of the United States is:
1. In gearing mechanism the combination of a support, a member hinged to the support, a vertical shaft in said member a pinion thereon, a reciprocatory rack bar for engagement with said pinion to oscillate the vertical shaft, means upon -the support to reciprocate said rack bar and having a pivotal connection therewith, a' guide upon the hinged member parallel with the rack bar and adapted to cause the same timove curately into and out of mesh with the pin ion as the hinged member is lowered or raised.
In a gearing mechanism, the combination of a support, a hinged member carried thereby,'a vertical shaft supported in said hinged member, a gear on the upper end of said shaft, a rack bar having driving engagement with said gear, a guide bar along which-said rack bar slides, a cell crank pivoted at the side of said support and connected to move said rack bar with a forward and backward motion with respect to said vertical shaft, a pitman connected to drive said bell crank, a crank disk connected to drive said pitman, a counter shaft on which said crank disk is mountetha power shaft, and a gearing between said power shaft and said counter shaft. 1
3. In a gearing mechanism, the combination of a power shaft, bevel gears loosely mounted thereon, a sliding clutch member movable along said shaft into driving engagement with either of said gears, a counter shaft, a bevel gear on said counter shaft permanently meshing with both bevel gears on said power shaft. a crank actuated by said counter shaft, a pitman driven by said crank, a vertically disposed rotary shaft, and means for driving said vertical shaft from said pitman with an alternately reversing motion irrespective of the direction of rotation of the counter shaft, whereby reversible mechanism may be directly driven from the latter. I
In witness whereof, I hereunto subscribe my name to this specification in the'presence of two witnesses.
