ARTHUR L. DUNCAN, OF OAKLAND, CALIFORNIA.

COMBINED WASHING AND CONVEYING- APPARATUS.

aeaeas.

To all whom it may concern:

Be it known that I, ARTHUR L. DUNCAN, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Combined Washing and Conveying Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to the subject of canning preserved fruits, vegetables, and the like, and the principal object of the same is to provide an improved apparatus whereby the articles to be canned may be thoroughly washed, the rejected articles carried away, and the canned material conveyed to a point where the cans may be syruped.

In carrying out the objects of the invention generally stated above it is contemplated employing a table or bench which is provided with an elongated trough parti tioned to provide a plurality of washing vats in which a tray is mounted and adapted to be raised by hydraulic power, said vats being each provided with an independent communication with a source of hydraulic pressure whereby its tray is operated and also whereby the water is kept at a predetermined level within the vats.

The invention also contemplates a system of rope or other suitable conveyers for delivering the cans to each washing vat and for removing the filled cans therefrom and for conveying the rejected articles away from the vat.

In the practical application of an invention capable of performing the above stated functions, it will, of course, be understood that the essential features thereof are susceptible of changes in details and structural arrangements, one preferred and practical embodiment of which is shown in the accompanying drawings, wherein- Figure 1 is a transverse vertical sectional View of a table or bench showing the present invention applied thereto. Fig. 2 is a central longitudinal sectional view of the same taken on the line 22, F ig. 1. Fig. 8 is a horizontal sectional view taken on the line 33, Fig. 1. Fig. 4; is a top plan view of one of the trays used in connection with the washing vats. Fig. 5 is a side elevation of the same. Fig. 6 is a sectional View taken on the line 66, Fig. 5.

Referring to said drawings by numerals, it will be seen that the improved table or bench Specification of Letters Patent.

is composed of front standards 1 and-rear standards 2, which are connected by the brace rods 3 and 4, and which form a support for an elongated trough 5 which is provided with a plurality of equally spaced apart partitions 6 which divide the same into a plurality of washing vats 7. The rear standards 2 project above the said vats 7, and support a plurality of inclined shelves 8 the front ends of which are provided with strips 9 which prevent cans from rolling from the same. The rear faces of said standards 2 carry two conveyer frames 10 and 11 through which rope or other suitable conveyers 12 and 13 pass and which are used for delivering empty cans to the rear ends of the shelves 8, the cans being removed from said conveyers by an operative and placed into said shelves so that they will slide down the same and rest against the abutment strips at the ends thereof and thereby be within easy reach of another operative stationed in front of the vats 7.

The trough 5 carries an inclined shelf 15 at its front side upon which the cans may be supported while being filled. The rear portion of the trough has a board or plate interposed between itself and the rear standards 2, said plate being designated by the numeral 16 and having an endless belt 17 passing over it, said endless belt being divided by a longitudinal partition 18 so as to provide a compartment thereon for bringing the fruit, vegetables or the likewhich are to be washed and canned, and for removing the rejected article. A chute 19 is carried by said rear standards, the front end of the same projecting over the washing vats 7, and the rear end terminating in a hopper 20 whose discharge outlet is directly over the partitioned compartment of the belt 17 which removes the rejected articles.

A conveyer frame 21 depends from the front portion of the shelves 8 and over and through which a rope conveyer 22 passes, said conveyer 22 being adapted for removing filled cans from the vats.

Each vat 7 has an opening centrally located in its bottom from which is suspended a tube or cylinder 23 the base of which carries a coupling 24 which is in communication with a pipe 25 equipped with a threeway valve 26 and having an extension 27 which enters said vats through its front side. Said three-way valve 26 has its casing in communication with a source of hydraulic pressure. A plunger or ram 28 is slidably mounted in the cylinder 28 and has one end projecting into the vat 7. A flat tray 29' provided with perforations 30 is mounted on the projected end of each ram 28.

In operation, the empty cans are brought to the shelVes'S-and removed from the-concans isbrought-to the vats by means of the endless belt or conveyer 17, and by means of a switch or deflecting bar 31 carried by each vat and adapted to be swung over the fruit compartment of said belt, the contents or a part thereof is deflected into each vat and onto the tray .29 therein. The threeway valve 26 having been manipulated so that water in flowing through the pipe 25 and acting upon the ram 28 raises the tray and also said ram so that its escape .ports 32 will be within the va't, holds said tray above the'bottom of the vat and also assures of water being delivered for washing pur poses. By further manipulation of the valve 26 the water may be exhausted partially 'fromthe vat through the pipe extension 27,

to lower the tray, and thereby assure of the necessary agitation of the water to assure of a proper washing of the material on the tray. After the articles have been thoroughly'washed, .the better grade of'the same are deposited in the cans on the shelf 15 untilthe cans are filleda fter'whichthey are placed on the conveyer 22 and carried there- 'by to one end of the table for syruping &c.

The rejected articles are dropped onto the chute 19 and from thence discharged onto the compartment therefor of the belt 17, which carries the same to a suitable receptacle. The vats 7 are eachprovided with the usual overflow opening 33 in their rear sides, as is shown in .Fig. 1.

In Fig. 1 the conveyers '12 and 13 have beenshown with cans mounted thereon and ready to deliver the same to the shelves :8. The conveyer 22 is also shown with a can on the same, the can being'shown in an upright position and on its way to the end of the table to be syruped. Said figure also shows a power pulley or the like 34 adapted for connection with a source of power and mounted on a shaft '35 which carries an otherpulley 36 for operating the partitioned belt 17 It will be seen from .the foregoing that through the described system of rope conveyers the empty cans arebeing constantly delivered and the filled cans removed from the vats,:and alsothat a constant supply of material is being fed to each vat so that :the

ticles from the vats.

same maybe deflected thereto, and also provision is made for conveying the rejected ar- Another prominent and distinctive feature of the invention is in the use of the valve controlled source of water supply vvhich provides the necessary pressureto raise the plunger or ram; to-per- 'mit the exhaust from the ram to return to the supply pipe so that said exhaust is not wasted but may be used to wash the .fruit or Vegetables; :and also that through the described mann-er .of permitting the pressure to exhaust from the ram that the water in :the vats will be agitatedand-thereby prevent sediments'lodging on-the bottom of the vats, as wellasassure ofa thorough washing of .the fruits or vegetables.
