PEIROE M. Woon, OF NEW ROCHELLE, NEW YORK, AssIeNoR, BY MESNE ASSIGNMENTS, TO HOBART MANUFACTURING COMPANY, or TROY, OHIO, A CORPORATION OIOIIIOA f PATENT OFFICE- OON'VEYER MEOHANISM FOR WASHING MACHINES Original application led October 31, 1925, Serial No. 65,923. ,Divided and this applicationruled November 5, 1926.

rIhis invention relates to conveyer mechanism for washing machines.
The invention aims to provide a connection between racks containing articles yto be washed and a conveyer which is sufciently positive to prevent undesired slippage of the racks but Icapable lof yi-elding when necessary to prevent breakage of the articles contained in the racks.
The means by which this object is attained in accordance with the invention can bestbe understood by a detailed description of a practical conveyer mechanism embodying the invention, which is shown in the accompanying drawings, in which:
Fig. 1 is a side elevation of the conveyer mechanism indicating diagrammatically the casing of the washing machine in which it is contained; and
Fig. 2 is an enlarged fragmentary side view of one of the conveyer chains and a dish rack resting thereon, showing the engagement between the raclr and the chain.
The conveyer mechanism is provided for moving the articles to be washed through the casing 10 of a washing machine from an entrance opening 11 at one end of the casing to a discharge opening 12 at its other end. Any usual washing means may be provided to act upon the articles as they are carried through the casing. The conveyer mechanism includes, in addition to a number of racks 15 in which dishes or other articles may be placed, chains extending the length of the washing machine casing. The chains 20 run over pairs of sprockets 22, 23 mounted on shafts 24, 25 located within the washing machine casing and extending across it near its ends. The shaft 24 is driven from any con-l venient source of power.
To prevent the dish racks 15 from slipping on the conveyer chains, they are provided on ltheir bottoms with projections 16 formed by bends in metal bands 17 which are secured to each dish rac-k so as to extend along its bot-` tom at the side edges thereof. The projecf tions 16 have curved and inclined sides and tit between the rungs 26 of the chains and in curved recesses 27 on the upper side of the links of the chains. The inclined engaging surfaces of the rack projections and the chains have an important function in p preventing breakage of the dishes or of the machine when a dish rack becomes accidentally wedgedy against m-ovement in the machine, or when dish racks are held at the discharge end of the machine so as to preventthose in the machine from moving. In either case, the chains 4do not force the dish racks forward, but
merely raise the inclinedprojections 16 and the dish racks suficiently to pass under thev projections.
This application is a ldivision of my copending application, filed October 31, 1925, Serial No. 65,923. i
Vhat is claimed is:
1. In a dish washing machine, the combination of a conveyer and an article-carrier resting thereon, the opposed surfaces of the carrier and conveyer being provided with cooperating projections and recesses having rearwardly and upwardly inclined engaging surfaces, sothat the conveyer raisesthe carrier when the carrier is held against forward movement. Y
2. In a dish-washing machine, the combination of a conveyer chain, a rack resting on the chain and having a short tapering projection extending between the rungs of the chain.
3. In a washing machine, the combination of a conveyer chain having links Veach provided with a curved recessin its upper edge, and a rack resting on the chain Vand having a projection extending into the curved recess in a link of the chain.
In testimony whereof I have hereunto set my hand.
