BOTTLE-WASHING MACHINE.

I Original application filed October 13, 1923, Serial No. 668,352. Divided and this application filed November 24, 1924.

This invention relates to bottle washing machines and is a division of my application Serial No. 668,352, filed October 13, 1923, for bottle washing machines.

Objects of this invention are to provide a bottle washing machine in which provision is made for collecting the labels in a suitable receptacle, in which means are provided for preventing the labels from clogging the machine. and preventing the return of the cleansing liquid to the reservoir, in which accumulationof dirt in the spraying means is prevented, and in which means are provided for withdrawing the cleansing liquid from the reservoir and returning it thereto without causing undue agitation of the liquid in the reservoir. I

Further objects are-to provide a bottle washing machine in which means are provided for catching the labels, in which this means is readily removable to permit dumping of the labels, and to provide a machine having a screen over which the liquid passes and to so construct the screen and the holding means therefor that the screen may be rocked to a readily accessible position and easily removed.

Further objects are to provide a bottle washing machine which. is a unitary struc ture, and in which the electric motor and pump and associated parts are contained within the outline of'the machine to thusprovide a machine which is narrow and may be readily passed through the usual size of doorways without requiring subsequent assemb-ling;

An embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a plan view of the bottle washing machine, such view beingpartly in section and showing the machine with the conveyor removed for the sake of clearness.

Figure 2 is a fragmentary transverse sectional view on the line 2-2' of Figure. 1.

Figure 3 is an enlarged sectional elevation of the rear portion of the machine.

Figure 4 is a detail of a portion of the driving mechanism of the conveyor.

Figure 5 1s a section 1 detail showing the Serial No. 751,938.

may be of any desiredtype and has been omitted from the drawings for the sake of' clearness, as such means need not be specially constructed to cooperate with the machine and, as stated, any satisfactory or usual type of upper spraying means" may be employed. The machine comprises a conveyor composed of a plurality-of individual links 1 \vhiclrare provided with bottle receiving portions 2 adapted to receive the inverted bottles 3, as indicated ,in Figure 2.

The conveyor is carried by means of flanged rollers 4 at the outer endsof each of the links which travel upon outer tracks 5 throughout the straight stretches of the machine, and which run on flat. semi-circular or annular members 6 at the ends of the machine, as shown in Figure 1. The inner ends of the links 1 slide upon tracks 7 (see Fig-- ures 1 and 2) and are equipped with lugs 8 which, together with the flanged rollers 4, correctly position the conveyor. The inner track 7 is continued completed around the machine, as shown in Figure 1, and is provided with curved end portions 18'.

The 'bottles are advanced in a step by step manner'and during't-heir dwell or quiet periods are positioned directly, over the lel sliding rods 10 which are oscillated in opposite directions by means of racks 11, and an intermediate pinion 12 (see Figure 1), the racks 11 being secured to the rods 10, and the pinion 12 being, rigidly secured to a vertical shaft 13. The rods .10 are provided with dogs,indicated generally at 14, at a plurality of points along their length, and such dogs are adapted to en-" gage projecting portions 15 (see Figure 2) of the links 1' and to thus transmit a step by step motion to the conveyor and to engage the conveyor at a plurality of points on its. forwardly and rearwardly traveling stretches to thus minimize stresses, as deand is provided with a rock armor crank This 16, as shown clearly in Figure 4.

- crank is connected by means of'a pitman 17 a-horizontal shaft 21.

vided with a loosely mounted pulley 22 and to a continuously rotating crank 18 driven.

by -a worm wheel 19. The worm wheel'19 is driven by a worm 20 rigidly mounted upon This shaft is prois adapted to be rigidly connected with the pulley by means of a clutch 23. The clutch 23 iscontrolled in any suitable manner as by means of a link 24. operated by a lever 25 carried by a rock shaft 26. This-rock shaft is provided with hand levers 27 at opposite sides of the machine so that the operation ofthe conveyor may becon-trolled from either side of the machine. y

The pulley 22 is connected by means of a belt 28 with a small. pulley 29 carried on wall or front vertical partition 34 of the.

the shaft 30 of an electric motor 31 (see Fi ures 4 and 6). Y

. The washing system for the machine comprises a reservoir 32 located in the lower portion of the rear part of the anachine, as

shown in Figures 3 and 6. 'This reservoir is provided with a downwardly turned" out-.

let pipe 33 which passes through the front reservoir and into the inlet portion of a centrifugal pump 35 (see Figure 6). This pump is directly connected to .the electric motor 31, as shown in Figure 6, and it is to be noted that the pump and motor are set.

within the outline of'the machine upon the base plate or bed plate 36 thereof, and thus do not require additional weight for .the machine. The outlet portion 37 of the ump communicates with a fitting 38, such lilting being bolted through the side walls of the machine to the inlet fitting 39 of. the-lower header 40 (see Figures 2 and 6). The header 40 is provided with a plurality of nozzles 9' (see Figure 2) which project streams of water upwardly into the inverted. mouths of the bottles 3. It it; to be noted from Figure 1 that this header. is substantially U- shaped, and that the water or other cleansing liquid is passed into the header by means of the pump'fat one end thereof and sweeps continuously around the header, thus carryingwith it and discharging from point to point any 'dirt that may be carried by the water and by this action prevents the forniation of quiet places or zones in the header with the consequent'depositing of sediment at these points. It is of course to be understood thatthe other end of the header 40 is closed. As previously stated, an, upper 'accepte machineflows along the rearwardly slanting screen 42fis carried by a reenforcing frame screen basket. This wiper consists of a pair connected by transversely extending bars 53 is not shown in the drawings asthe 'upper at spraying means may beof any usual or type. The waste-water from the partition 41 (see Figure 3) and discharges on to a screen 42 (see Figures 1 and" 3). This screen is tilted downwardly towarcs the rearand any liquid or mate-rial Whichis not passed through the apertures in the screen is discharged into a wire basket 43 which is removably held at the rear of the machine. y

Immediately-below the screen a forwardly and downwardly .slanting deflector plate 44 I is provided and is equipped with an upturned ledge 45 at-its lowest end. .This'plate provides a sheet like stream of returning water and the ledge prevents the stream from acquiring such velocity as to stir up the liquid in the reservoir 32, but allows the liquid to flow into the reservoir with its velocity materially reduced. It is necessary, as shown in Figure 3, to provide a .basket with a high rear wall 46 to insure the retention of any material washed downwardly from the screen 42. It thus becomes necessary to provide additional means for per mitting the ready removal of the screen. i As may be seen from Figures 3 and 5, the

47 which is slidably carried within side chanside walls of the machine. In this way the. screen may be readily removed by IOCkillg the channels 48 upwardly until the line of 1 such channels i's'a bove the rear wall 46 of the" basket and above the adjacent portion of the machine. hen in this position, the

screen may be readily slipped from the vide access to this portion of the apparatus.

If desired, a spring latch 51 may be carried by the frame 47 and contact with the basket It frequently happens that in bottle washing machines the labels' clog any screen mechanism that may be provided. This defeet in the operation of the machines as heretofore constructed, is wholly "overcome in the practise of this invention by providing a wiper adapted to travel back and forth across the screen and to sweep the labels and in trash rearwardly therefrom and. into the of side members 52 adapted to travel upon the channel members 48, as shown in F igures 1, 3 and 5. These side members areso that in effect a crosshead is formed.

'A flap consisting of a main body" portion '54 and a rubber or other strip 55 (see header or spraying means isprovided but Figure 3) is 'pi ally mounted adjacent its nels 48. pivoted, as indicated at 49, to. the

ends between the end members 52. The body .portion 54: of this flap is hinged to the outer end of a pitman 56. y The inner end of the pitman is pivotally carried by a small truck 57 provided with wheels58 which travel upon the partition 41. The forward end of this pitman is provided with a counter balance 59 so that the rear end of the pitmau does not press downwardly upon the pivotal joint with the flap 54. This truck is connected by means of a short link 60 (see Figure 3) with the lower end of a lever (ll the stop 65.

which is pivotally carried by bracluts '62 secured to stationary portions of the machine body. The upper end of the lever 61. is con nected by means of. a link 63 with a" bracket 64 attached to one of the oscillatory rods 10.

It'will be seen, therefore. that as the rod 10 reciprocates, the lever 61 will be rocked back and forth between its -full line and dotted line positions, as indicated in Figure 3, and consequently the pitman 56 will be drawn back and forth. \Vhen the pituian is drawn inwardly the flap 55 is raised by rocking the main flap 54 about its pivot point, as indicated in dotted lines in Figure 3, thus causing its upper end to contact with Thus while the crosshead is being retracted the flap is in elevated position and does not draw the labels or trash inwardly along the screen 42. However. when outward motion is imparted to the pitman. the flap immediately rocks downwardly and itsrubber or other lip 55 Wipes outwardly across the screen 51 and'thus wipes or pushes the labels or other trash from the screen 42 into the basket 43. When the flap is rocked downwardly into its full line position. as shown in Figure 3, its upper end contacts with the stop 66 thus preventing further rocking motion of the flap. In this way clogging of the screen mechanism is wholly avoided by this invention.

It maybe further advantageous to provide a definite track for the cross head to slide upon. This is readily accomplished by providing tracks such as the inverted V-shaped tracks 67 shown in dotted lines in Figure 5; These tracks or rails may be secured to the upper'sides' of'the'channel members 48.

It will be seen that a bottle'washing Ina-v chine has been provided in which all danger of clogging of the machine by labels or trash has-been avoided, and a free flow of have been provided for keeping the slanting screen free of labels and trash and insuring 4 be seen that positively operated screen wiping or cleaning means free and uninterrupted straining of the liquid. i

Although the invention has been described in considerable detail, it is to be understood that the invention may be variously embodied and is, therefore, to be limited only as claimed.
