DISH-CLEANER.

SPECIFICATION forming part of Letters Patent No. 512,683, dated anuary 1 6,

Application filed February 26, 1892. Serial No. 422,868. (No modell To all 'whom it may concern,.-

Be it known that I, JOSEPHINE G. COOH- RANE, a citizen of the United States, residing at Shelbyville, in the county of Shelby and State of Illinois, have invented certain new and useful Improvements in DishWashing Machines, of which the following is a full, clear, and exact specification.

My invention relates to improvements in machines for Washing dishes, in which a continuous stream or streams of either soap-suds or clear wateris injected through a crate'or reel holding racks or cages, containing dishes to be washed, while the crate or reel is rotated so as to bring as near as possible all surfaces or portions of the dishes under the action of the water; and my present invention is more particularly designed as an improvement upon machines of this character shown and described in United States Letters-Patent No. 355,139, granted to me December 28,1886, and No. 391,782, granted to Jacob Kritch and myself jointly, October 30, 1888, and to which patents reference may be had for an understanding of any features not fully described herein. l

One of the main objects of my present invention is to provide simple and effective means for giving the reel a continuous as contradistingnished from an intermittent rota- 'tion while subjected to the action ot` the water.

A."nother object is to provide the apparatus with a simple and automatic detlector for diverting the water as it runs from the crate or reel, into the proper compartment vor cham- A'ber below, as in my aforesaid patents, and to do away with the depending arms heretofore used for supporting and shifting such deflector and at the same time to greatly'reduce the detlector in width.

A further object of my invention is to provide the device with means for supporting two reels or crates at one time, rso that one ot the same may bev on the inside of the washing chamber and the other on the outside in aposition to be unloaded or refilled with articles to be washed.

A further object ot' my invention is to provide an improved crate or reel which will automatically lock or clamp the dishes therein when the cover ot' the reel or crate is closed down and automatically release the same when such cover is open. A

A still further object, is to provide an improved form of basket or kit, which shall be capable of securely holding thev disheswhile in the reel, without damaging or marking the same, as has been the case heretoforewhen iron or metallic baskets or kits have been ern# ployed.

With these ends in view, my invention consists 'in certain features "of `novelty in the construction, combination and Varrangement of parts hereinafter fully described, in connection with the accompanying drawings and more particularly pointed out in the claims.-

Aplan view illustratingthe'mechanism for raising and lowering the doors of the washing chamber, the front portion of the machine being broken away. Fig. 5, is a perspective view o f the reel supporting carriage, drawn to asmaller scale. "Fig 6, is a vertical longitudinal sectionof the dish 'reel or crate taken onv the line 6-f6, Fig. 7. Fig. 7, is a vertical transverse section of the same, taken on the line 7-7, Fig, 6. Fig. 8, is a detail view of the locking and releasing mechanism of the crate vor reel, hereinafterdescribed, the section being taken on the line 8 8, Fig. 7.- Fig. 9, is a. detail viewot the sliding locking rack and the end of the follower, for holding the dishes in the crate or reel, showing a spring dog on such follower about to engage the teeth of the rack. Fig. 10, is a detail view of the follower in side elevation. Fig'.y11,is a plan view of' the same. Fig. 12, isa perspective view of the dish basket or kit, and Fig. 13, is a sectional view of the same,show A.ing the manner of holding the dishes therein.

In the drawings, wherein like signs'of reference indicate like parts throughout the several views, 1 is a'frame or casing provided- Fig. 2, is a vertical longitudi-` IOO with a washing chamber 2 having open sides, which are closed preferably by vertically sliding doors 3--4, respectively, which may have any suitable means for elevating them. The meansshown for accomplishing this and which I prefer to use, consist of two racks, 5-6, arranged in a vertical position at or near the end of each of the doors, which are engaged respectively by pinions "78, secured to horizontal shafts 9, one at each side of the machine and preferably at the upper edge or corner of the frame, 1. Each of these shafts 9, is provided with a beveled pinion 10, which are respectively engaged by similar pinions l1, secured to a crank shaft 12 journaled at the back of the machine and being provided at each end with a crank or handle 13, by means of which a rotary movement may be imparted to the shafts 9, which will consequently impart thedesired movement to the doors, 3 4; thus causing both doors to be elevatedor lowered simultaneously. Each door, if desired, may be provided with a counter balance 14, attachedthereto by means of asuitable cord 15 Working over pulleys 16 mou-nted in a cross bar 17 above the machine.

As in my aforesaid patents, situated below the Washing chamber 2 and extending longitudinally thereof, are two independent water chambers 18-19, covered by a suitable sieve or screen 2O and being for the reception of clear or rinsing water and soap-suds, respectively,.or any other cleansing solutions. rlhese chambers 18-19, project forward beyond the casing l, into pump chambers 21--22 respectively, in which are respectively situated the pumps 23-24, as in my aforesaid patents, and from these pumps extend the eduction pipes 25-26 respectively, which, however, unlike my aforesaid invention, are provided throughout their horizontal portions, which extend through the washing chamber 2 over the reel, with a series of flattened or fan shaped nozzles 27. These nozzles 27 are so arranged that their longest diameters will be lengthwise of the crate or reel, so as to direct a continuous sheet of water upon the reel fromendto end thereof and thus subject the entire surface of the articles to be cleansed tothe action. of the water.

Arrangedat each end of the washing chamberi2,`transversely thereof, is a track or way 28,.which extends slightly beyond the frame 1 on both sides, as more clearly shown in Fig. 3,l and is provided at each of its extremities withany suitable stop, such as upturned or curved portion 29. Mounted upon these 4tracks or ways, is the reel carriage` 30,` each ofwhose side pieces 3l isprovidedat each end with any suitable anti-friction device, such for instance, as a grooved roller 32, which. rollers rest upon the tracks 28 and thus support and guide the carriage as it is shifted from one side of the `machine to the' other, the side portions 3l of the carriage being tied together by a suitable brace-bar 33.

At each end of each of the side portions 31,

is formed an open journal bearing 34, in either pair of 4which one of the reels 35 havingjournals36 may be mounted. In practice, however, it is desirable and advantageous to mount one of the reelsin each end of the carriage, as shown in Fig. 3, so that one reel may be on the inside of the chamber 2 sub jecting its contents to the action of the spray pipes, while the other may be on the outside in a position to be emptied and refilled, if desired. Another important advantage in this construction and manner of use, is that each of the doors may be provided with a blade or other suitable spring 37, one of which, when the doors are closed down in the position shown in Fig. 3, will engage or press against the side of the crate on the outside and thus not only hold such crate firmly in position, right side up, but subserves thefurther useful function of maintaining the journal 36 of the reel in axial alignment with a clutch 3S, by means of which the reel isrotated. One of the springs 37 is secured at its upper end to each ofthe doors atabout mid- Way of the length of the door and has its lower end resting freely against the outer side of the door, so that when the door is lowered as shown in Fig. 3, the spring willcrowd-between the side of the outer reel' and the` door and prevent such reel from turning, while at the 'same time, the carriage 30, upon which the reels are mounted, will be secured againstinward movement` and the inner reel consequently held in its proper position.

The journal 36 at one end of the reel is preferably provided with a cavity 36 prismatic in form, so as to be capable of receiving a square orlprismatic clutch 38 formed on the inner end of the reciprocating shaftor stern 39, suitably mounted with capability of rotation, in a sleeve or journal bearing 40,se cured to the end of the frame l. The outer end of the shaft 39. may be provided with any suitable mechanism for imparting an endwise movement thereto, so as to engage and disengage the clutch 38 with the socket in the journal 36, but I prefer to employ an eccentric 41, whose strap is connected to the end of the shaft 39 by means of a link 42, and whose shaft 43 is mounted in suitable bearings 44 formed'on or secured to the up-` rights or stanchions 45, and provided at its extremity with suitable operating handles or cranks, 46.

47 is the main driving shaft., mounted preferably on the top of the casingor frame l, longitudinally thereof, in any suitable bear ing 48, and being driven by an engine or any other suitablemotor or power. The end of this shaft 47 is provided with a beveled pinion 49, which engages with a beveled gear wheel 50 mounted upon and secured to` a cross shaftl, which has its bearings 52 in the upper ends of the standards or stanchions 45, as more clearly shown in Fig. l. This shaft 5l, is also provided with a worm 53, which engages with the worm wheel 54 se- 512,683 l i i s cured to the end of the vertical or upright shaft' 5,5, mounted in suitable bearings 56, se=

cured to the frame 1; and at the lower end of, or other convenient point on this shaft 55, isy secured a beveled pinion 57, which is so arranged as to be engaged by a similar pinion 58, secured to the shaft 39, when such shaft is pushed inward toward the reel, as before described; but, of course, any of the other well known mechanical expedients for establishing a connection between the shafts 55 and 39 might be employed without departing from the spirit of my invention.

The pump piston rods 59, areprovidedat their upper ends with any suitable guides 60, and arranged to slide upon but otherwise disconnected with these piston rods, is a crosshead 6l, whose extreme ends are shown as turned backward slightly, so as not to interfere with the standards 45, and are suitably connected by means of pitmen or connecting rods 62 with wrist pins of the crank disks 63,

which latter are secured to the extremities ofthe shaft 51, and thus cause the cross-head 61 to reciprocate up and down on the piston rods 59 during such time as the shaft 51 may be in operation. i

Inasmuch as it is desirable that but one pump should be operated at a time, and that both should be inactive while the doors of the chamber 2 are open for removing or replacing the reels, it is necessary to providey the cross-head with some means for detachably connecting it with either or disconnecting from both of vthe piston rods. 'The means shown and which I prefer toemploy, consist of a bolt 64, mounted in suitable boxes o1' guides 65,y secured to or formed upon the cross head 61 and provided at or near its midlength with a rack or series of teeth 66,which are engaged by a segment rack 67, pivoted to the cross-head and having a suitable operating handle 68; and on the piston rods are secured respectively notches or keepers` 69- 70, into either of which'the bolt 64 may be projected, by means of the lever 68, and thus cause the operation of the pump on that side until such bolt is shifted to the neutral or central position, so as to be out of engagement with both keepers, or into engagement with the opposite keeper.

For locking the bolt in the desired position,

the cross head ,may be provided with a locking rack 71 having suitable notches, as shown in Fig. 1,in which notches engages a suitable locking dog 72 pivoted to the back of the lever 68; or any other` preferred means vmay be employed.

Arranged just above the screen20 in the chamber 2, is a suitable, divided, horizontal partition,which preferably consists of two removable inwardly` inclined slides 7 374, adapted to be inserted lthrough the doorways of the chamber 2q and to rest upon guides or J any other suitable supports 75, such slides terminating at their inner ends under the axis of the inner crate or reel, and at ashort distance from each other, so as to permit the water flowing from either of the pipes 25-26,

to run off into-the lchambers 18-19 below. In order, however, that the water injected throughone of the pipes 25-26 may be kept separate from that which is injectedy throughy the other of such pipes, and may be caught in one of the chambers 18-19 only, I arrange immediately under the inner ends of the slides 73-74, a tilting deilector 76, which is i mounted upon a horizontal shaft 77'in sucha position as to overlap the under side of either of the slides 73-74'when tilted in an inclined'position, as more clearly illustrated in Fig. 3. Thus, it will be seen that the water discharged by either of the pipes 25-26 will be compelled to run'o into but one of the chambers 18-19. The outer end'of this shaft 77 is provided with-a crank arm 7 v8, which passes through a swiveled lug 79 on.y the end of a depending arm 80, secured to or formed on a rocking lever 81, which latter is pivoted at. 82 on the support 83. The crank arm 78 has sleeved upon it between the shaft IOO the piston rods with rearwardly projecting l arms 85, rigidly secured thereto in any suitable manner and projecting under the ends of the lever 81, so that when either of the piston rods is operated, the lever 81 will be'oscillated uponits pivot, if at the beginning of the operation of such piston rod the end .of the lever 81 on that side is in its lower posi` tion. rlhese arms 85 may be guided at their rear ends by any suitable guides or ways 86, consisting for instance, of ordinary channel irons secured by ears 86a to the end of the casing l for preventing the rot-ation of the piston rods, and thus at the same time avoiding the possibility of the keepers or notches 69 shifting out of position by the rotation of the piston rods; and such arms 85 are arranged at such positions with relationto the lever 8l, that the lever Willbe tilted or thrown upward at one end at the first upward stroke j of the piston and will remain in this position until the other pump is started. y In order that access may be had to the inte-A riors of the pumps and the chambers in which they are situated, for cleaning the same, I have provided the upper ends or sides of these chambers 21-22, with a removable deck-or cover 21a which is provided in its inner endu or edge with two slots 21" forjthe passageY of the pi-ston rods when the deck is being slipped into place. These slots 21b are provided-With doors 21C, pivoted to the deck Vat 21d-seas to swing to and from said slots; and the ends of these doors are provided with semicircular notches 2lc for partially encompassing the piston rods.

The reel preferably consists of a rectangular frame 87 provided with a suitable hinged lid 88, and such reel is adapted to receive any suitable basket, such as that shown in Fig. 12, for containing the dishes to be cleansed. The basket is held in posit-ion in the bottom of the reel so as to avoid breakage or rattling of the 'dishes while the machine is in operation, by means of the follower 89, whose ends are provided with spring dogs 90 connected together at their outer ends by a cross-'bar 91, which is adapted to engage with the toothed locking bars or racks 92, two of which being preferably arranged at each end of the reel. Each pair of these racks 92 are provided with a con- `meeting cross bar 93, at or near their upper ends and with a similar bar 94 near their lower ends, and the bar 93 is preferably provided with an upwardly projecting post or lug 95, which is arranged to be impinged by the lid 88 when the latter is closed, thus forcing the racks 92 downward against the action of a spring 96, secured to the bar 94 and to the end of the reel, and thereby projectingthe teeth of the racks 92 beyond fixed plain-edged guard bars 97 arranged parallel with each of the racks 92, and causing such teeth to engage over the cross bars 91 of the spring dogs 90 and lock the follower in position.

The plain edged bars 97 are secured at 98 at both ends, to the frame of the crate or reel, and are provided with inclined slots 99 in which work suitable pins or lugs 100, formed on or secured to each of the racks 92, thus causing such racks, when forced downward by the action of the lid, to ride inward in the manner described, for engaging the spring dogs 90, and to ride outward under the inliuence of the spring 90 when the lid is opened, and thus withdraw the teeth beyond the plain edged bars 97 and permit the ready withdrawal of the follower. The lid, of course, may be provided with any suitable catch or latch for holding it closed. The ends of the spring dogs thus constituted by the springs 90 and cross bars 91, are capable of perpendicular movement independently of the follower, and hence the follower will be held upon the dishes by a yielding pressure which will avoid damage to frail articles.

Great difficulty has heretofore been eX- perienced with iron or metallic baskets for holding dishes, owing to the fact that even when such baskets are enameled, the enameling soon wears off and leaves the exposed metal to mark and mar the dishes. In order to avoid this objection, I have constructed a basket of wood, which, while sufficiently strong `and rigid to hold the dishes firmly in position, not only prevents the marking thereof, but avoids chipping fine china and the rattling thereof while in the machine.

The form of basket which I have found to be most efficient for holding flat ware, consists of two rectangular frames, 1014-102, forming the top and bottom respectively, which may be connected together by slats or strips 103, composed of wood, rattan or bam boo. The frame 102, is provided with a central piece 104, through the middle of which are planted a number of short pins or posts, 105, between which and the horizontal ribs 103, the flat articles may be situated, as more clearly shown inFig. 13.
