2 Claims.

For a detailed description of the present form of my invention, reference may be had to the following specication and to the accompanying drawings forming a part thereof.

My invention consists in a bottle washer organized to perform automatically all of the operations required in cleansing bottles.

These operations include a preliminary rinsing,

a soaking in a tank containing a caustic solution, an emergence from the tank with an amount of said solution therein, a scrubbingboth internal and external, a draining out of any solution remaining therein, and a final rinsing with fresh clean water. Means are provided for keeping the bottles moving through the several operations outlined above, beginning at the start, when vthey are first applied to the entrance conveyor and continued up to their nal delivery on the reception platform. This reception platform is located at the same end of the machine at which the bot- Together with the conveyance just mentioned there are, in addition, auxiliary means for transferring the bottles from one conveyor to another at succeeding stages, including the ternporary ejection from the conveyor for washing, and their iinal ejection and setting up when the operations are finished.

Iwill rst describe the operations and will then describe the mechanism that performs them.

Fig. 12a shows the carriers or buckets of the main conveyor.I

The machine in general comprises a rectangu- .lar casing of sheet metal preferably left open at the center. This casing, with attachments, is about twelve feet long and six feet high and its width, or horizontal depth, is dependent on the number of lines of bottles passing through it in parallel lines. With four such lines the width, or depth, is about four feet. The capacity of the machine may be changed by adding to, or subtracting from, the number of such lines of travelling bottles.

In this casing there is one fundamental conveyor, travelling intermittently in a rectangular circuit, and consisting of two or more parallel chains moving over guides and bridged across at intervals by a series of upstanding sheet metal cells. buckets or carriers. This main conveyor is illustrated in detail in Fig. 12B, wherein the several chain links are marked A1'I and the rollers B1". Each link is formed with a bracket a1'I to which is riveted one end of a set of sheet metal carriers D11. There are in this illustration four such carriers in a set, and the remote end of the set is similarly attached, as shown in Fig. 12, to a corresponding bracket all in a parallel chain on the opposite side of the machine. The cells, .buckets or carriers stand above the chains in Fig. 12, but on'the bottom rim of the machine they will project below the chains, and will project to'right or left of the chains on the vertical rims. Just above Fig. 12a is Fig. 12, which shows a cross section of the top length of the rectangular casing,.and in this Fig. 12 these carriers D appear in section with a bottle in each. These carriers D1'1 are open at each end for admitting or removing the bottles and are somewhat larger in cross section than the bottles inside of them. That is to receive different szes of bottles and to avoid a tight llt.

In addition to the main conveyor aforesaid,

there are various short auxiliary conveyors; sim- Eli) ilar in principle, that lead to or from the main 011e.

Referring to Fig. 1 (Sheet 1) the start of the operation is there shown. At the right of the figure is an auxiliary conveyor, which we 'may designate as the entry-conveyor", for the bottles to be washed are rst applied to it. Its details are shown in the small Fig, 1a on the same sheet. A top view of the entry conveyor and the bottle holders for the lbottles applied to this conveyor appears in Fig. 4, Sheet 4. It comprises two parallel chains E2, of which only one is shown in Fig. la, the links thereof being connected across at intervals by bridge plates E5 on which are the bottle holders E5 and E5. The head of the bottle is dropped in the socket-shaped part E5 of the holder, while the body of the bottle lies against the bracket-like part E5. Thus the bottle stands bottom-up in the holder at a slight angle (see Fig. 2, Sheet 2) when in place on the entry conveyor. The upper run or length of this entryconveyor moves to the left in Fig. l advancing the bottles toward the machine. This entry-conveyor is located on the right and in line with the main conveyor, see Fig. Li. The receiving table X20, at which the washed bottles finally arrive, is located at the same end of the machine, back of the said entry-conveyor and to the right thereof, looking toward the machine in Figs, l and As the upstanding bottles move to the left, being guided by the rods F5 extending along their sides, as shown in Figs. l, 2 and ll, they enter between the prongs of a forked guide F1 (see Figs. l and 1l) and are thereby steadied as they, one by one, reach the position of the last holder on the top run of the conveyor chain it this position they receive the preliminary rinsing jets from the nozzle F1 below them and .from the nozzle F2 above the bottle, in the spraying hood The water from nozzle F2 washes the outside and that from nozzle F1 the inside, of the bottle. The water from the rinsing collects in the sink F5 at the bottom of the enclosure and goes out by waste pipe F15, as appears in Fig. 2, Sheet 2. After being rinsed by these jets, the bottle, as it starts to turn over, strikes the weighted and pivoted guide g1. It4 is the side of the bottle near its bottom end that collides with this guide g1 and the bottle is thereby twisted out of the holders E5, E6 and drops, neck foremost, into aninclined chute G1.

The chute G1 leads the bottle to the main line of carriers D17 which are shown, on the left-hand side of Fig. l, as moving downward on their vertical rims. In Fig. 2b, Sheet 2, a bottle from chute G1 is seen entering a cell or bucket D17 of the conveyor, while from the next higher cell or bucket D17 a bottle which has finished its washing experience, is emerging. The said chute G1, besides being pivoted at its right hand end by the pivot y2, as shown in Fig. 1, is also pivotally supported at its left hand end by `a long vertical link gi which is attached at its upper end to a spring g as a support for one end of a trough W1o hereinafter to be described. By this means, should there be any failure in the alignment of the mouth of chute Gluwith the mouth of the bucket on D17, into which the chute delivers the bottle, the chute G1 Will yield vertically to meet the mouth of the bucket. In the'event of such misalignment being too great, the movement of the chute will be suipulling down on the link g3. The inside surface driven.

Intermediate its ends the link g3 is also used of chute G1 is ribbed on the bottom, as shown at g5 in Fig. l, to provide for the smooth sliding of the bottles therein. As leach bottle enters a bucket it is positively pushed from behind by a pad J1 on the end of a lever arm projecting from a shaft J5 which is rocked by means of a link J 6 as shown in Fig. l.

The bottle has now reached the main conveyor and has entered a bucket therein. The conveyor transports it downward into the lower horizontal part of the casing which forms the soaking tank, as may be seen in cross section in Fig. 11. In this tank is the coil of pipes H12 which carries hot water for heating the tank. In this Fig. 11 the tops of the bottles, projecting above the buckets D17 are shown at K12 and their bottoms appear at K13. The buckets, being open at both ends, become iilled with the solution from the tank, which solution is of a caustic nature, and travel slowly along horizontally to the opposite end of the tank where the conveyor-chain turns upwardly bring ing the bottles to the scrubbing apparatus, as may be seen in Fig. 7, Sheet 7. For the scrubbing operation the main conveyor is stopped for the time required by that operation. It may be said here that the main conveyor is also stopped for the nal removal of the bottles therefrom at the end oi the operation. The intermittent movement of the main conveyor will be explained later.

In Fig. 7, the bottles, moving 'upward in the buckets, as shown at the left, are pushed. out of the buckets, by pushers O7, on the end of pusher rods O5, against the brushes. The body brush R7 is best shown in the sectional appearing in Fig. l1, Sheet ll. The sections of the brush are carried by a link-chain which passes over the sprocket wheels R12, R12 by one oi' which it is This brush bears against the under side of the row of four bottles, and the bottles are pressed down against the brush by a flexible belt R5 which runs parallel to the brushes over the two pulleys R5 and, on its lower branch, over three smaller pressing rolls R11, R5, R5. The two end rolls Ra are mounted respectively on two angle levers R9, R9, while the central roller R5 is carried by a smaller angle lever R1n and pressed downward by a spring T which is connected by a rod and spring arrangement T1 to one of the levers R2. When the angle-lever R1 presses the small pressing roll R11 against the belt-R5, the rod T1 is pulled to the right in the view shown in Fig. 11, thus compressing spring T which bears against a portion of the angle-lever R10 whereby to thrust the central pressing roll R8 downwardly. Each of the said angle levers R9 carries a roller V12 on its outer leg which is positioned' adjacent rods O4. 'I'he rod O1 is provided with a short cam V13 and, in the longitudinal movement of the rods O4, the cams V13 thrust the rollers V12 outwardly and upwardly .to accomplish the tightening of the flexible belt R5. A plan of the flexible belt R5, its pulleys R5 and the rollers R8 appears in Fig. 6, Sheet 6. It is by means of this exible belt R5 that the bottlesare kept in rotation while the brushes bear upon them.-

The flexible belt R5 is driven by means of a chain R50 extending between and around sprockets R51 and R52 Whichare respectively mounted on shaft 3 and Qnthe shaft R53 supporting the pulley which carries belt R5 as shown atV the left in Fig. 11.

Referring again to Fig. 7, wherein the body brus'n R7 is shown inlongitudinal section bearing against a bottle, there is similarly shown the neck brushes U5, and U5 which bear against the outside the pusher. thebottles are carried upwardly by necks of the bottle. There is a pair of these neck brushes for each bottle, the upper one being carrled by a spring arm u1 and the lower one by a similar spring arm u2. carried respectively by rockshafts S10 and S12, as appears in Fig. 9. As shown clearly in Figs. 6, l and 9, the collars and extensions therefore S5 are keyed to the rock shaft S10 and provide mounting surfaces for arms u1. The rock shaft S10 'is provided with an upstanding arm 46 to which spring U5 is attached. The spring thus normally retracts the brushes U5 and the upper endv of the spring U3 is attached to the frame adjacent the part E10, as shown in Fig. '7`. Y n v From shaft S10 project downward the arms B0 and from shaft S12 project upward thev corresponding arms B1.

50, 6 and 7 (hereinafter described) moves back-A As the mouth-piece S11, Figs.

Ward away from the bottle, it hits the said arms B0 and B7 and rocks the shafts S10 and S12. forces the said spring-arm u1. which carries neckbrush U5 down and spring-arm u2, which carries the other neck-brush U5 up, into contact with the neck of the bottles. This contact continues until the mouth piece S1*1 again moves back,.to push the bottles back into the carrierV cell or bucket. Then it releases the said arms B5, and B7, and the spring U3 (Fig. 7) lifts up arm u1 and brush U5, while arm u2 and the other brush U5 drop of theirown Weight. s

There is also a brush Y2 for the outside bottom of the bottle, and this is shown in Fig. 5a in its retracted. position and in Fig. 7 in its advanced position. AIt is mounted on and forms the front face of the aforesaid pusher O'I on the rod O0. By this means the effect of friction against the rotating bottle by reason of the impact of the pusher on the rotating bottle is averted, and the cleaning of the bottom of the bottle by its rotation against the brush Y2 which intervenes between the bottle and the pusher O", is ensured.

When the bottles are pushed out of the buckets of the main carrier by pusher O7, they come out horizontally between the body brush R" below and the exible belt R5 above. In consequence they then have no rigid centering. Yet a definite centering is required, if an inside brush is to be entered through the mouth and lneck of the bottle to scrub it internally. I therefore provide for such bottle a beveled mouth piece S1l1 (see Fig. 7, Sheet 7, and Fig. 5a and Fig. 6), which may be moved up against the mouth of the bottle, as

shown in Fig. 3. when the bottle is moved back into the conveyer. The level of this mouth piece S1'1 will centralize the bottle on its emergence from the conveyer and while itis still being rotated by the flexible belt R5. While the bottle is thus centralized, I project into it, through its mouth, an internal brush K4 (Fig. 7) mounted on a rod K5 which is thrust out through the center of the aforesaid mouth piece S14. The bottle is rotating in one direction while the internal brush K4 is rotated in the opposite direction by the chain C40 as appears in Fig. 6. Therefore the brush K4 serves to scrub the inside of the bottles just as the These arms, u1 and u2, are` That the conveyor and then horizontally, along the top length of the conveyor route back towards theirstarting point. The re-entry of the .bottles into the carrier buckets after the scrubbing is accomplishedby the reverse stroke of the pushing-out means. This will be described later when I take up the motive mechanism of the apparatus.

When replaced in the carrier-buckets after scrubbing the bottles travel, as just stated, upwardv therewith and then turn to a horizontal line of travel for the purpose of rinsing and draining out.

mouth downward, come to a different form of track on which the bottle mouths bear. This track is open to permit lthe exit of the water,

For draining purposes `rthe lower ends Aof the bottles, which are now travelling and under it is a pan P20 (Fig. 7), to receive the Water. This pan P20 forms the bottom of the upper horizontal reach of the main casing. This special track aforesaid is shown in plan at Fig. l0, Sheet l0, and in more detail in Fig. 8, Sheet 8, and in thev cross section at Fig. 9, Sheet 9.

In these figures N1 and N5 represent a pair of parallel rails or rods, which I term guards, there being such a pair of guards for each of the four lines of travelling bottles. Between each pair of guards N4 and N5 and at a lower level runs a narrow rail N0 standing on edge. As appears in thecross section, in Fig. 11, the bottle mouth rests on this knife-edge rail N0 with. the guards N1 and N5 on either side of the bottle head. The wheels B17 of the carrier chain run on the outside .tracks N9 and N10 formed by flanges on the inside of the casing. Justfbefore the bottles reach this special drainage track they ride on the normal form. of rail shown at N" and N0 in Fig. 10.

. and from said rails N"I and N8 the bottles slide off onto the rail N5 as just mentioned. The guards N1 and N5 are formed in sections, and, as clearly .appears at the left of Fig. 8. springs QQ are interare carried by a shaft X100. Shaft X is mounted upon and between adjustable slides X11 which are supported between the spaced arms X12 of `a frame bracket X13. Slide X11 is provided with an ear X11 and the frame bracket X13 is provided with a corresponding ear X15. Extending between and through these ears is an adjusting boltvX10 which, when tightened, draws -the slide X11 upwardly to thrust'the shaft X100 and the sector N'I radiallyoutwardly of the entire apparatus whereby to tighten the conveyor chain A1".

In the length of the aforesaid rail N0, there are included at intervals the spray nozzles F20, as appear in Figs, 7 and 10. The water comes to these nozzles,`F20, by cross pipes L10 (see Fig. 10, also Figs. 10E1 and 1015,` Sheet 10), which branch from the main water pipe L15. At each paint where a cross pipe L10 branches from the main L15 there is a cut-off valve L20, the details .of which are shown in Figs. 1011 and 105. In Fig.

100 that valve is open and from the main L15 Water can flow freely through a hole in disc L20 to cross pipe L10 and the nozzles F20 thereol But the said disc L30 is fixed to the pipe L10 and by a slight rotation of said pipe L10 the disc L20 may be also rotated to cut off the flow from main L15 as shown in Fig. 100. The required cutoff rotation of the pipes L10 is afforded by the reciprocating rod E10 which works a link E20 that is connected to a short lever arm E15 on each of the cross pipes L10. 'I'hus by means of the rod E10 all of the spray nozzles may be turned on or turned off simultaneously. The sprays from nozzle F20 are of fresh water to remove the caustic water remaining on the bottles after their soaking in the bottom tank which I have heretofore described. Referring to the showing of the aforesaid spray nozzles F20 in Figs. 7 and 10, there is shown mounted on the cross pipe L10, adjacent to each nozzle, a lug G10. As each bottle comes into a vertical line with a nozzle F20, this lug G10 is raised, by means just described, for rotating pipe L10, to turn on the spray. The lug hits the head of the bottle from behind, and thus makes the bottle stand up straight for receiving the spray through its mouth, whereas the bottle would otherwise stand in a slightly inclined position, as heretofore stated. Thus in Fig. 'l each bottle that is directly over a nozzle F20 is standing up vertically, the setting-up lug G10 being up against the bottle mouth. On the contrary, the other bottles are in their normal inclined position, due to the fact that the carrier buckets are larger in diameter than the bottles to allow of the free movement of the bottles into and out of the buckets, and avoiding a tight t such as would involve extreme accuracy in the spacing of the brackets with respect to the bottles. Such accuracy would be impractical. Moreover the large sized buckets will permit of bottles of differing sizes up to the limit where the bottle would t too tightly.

Besides the internal rinsing of the bottles by the spray nozzles F20, which I have just described, they are also rinsed externally by sprays directed on them from above. This is shown in Fig. '7, at the top of the figure, where two sprays R10, R10 are also applied to the outside of the bottles. It is also shown in the sectional view of Fig. 9.

After being rinsed, as I have just described, the bottles on the carrier are transported by the main conveyor to the end of the machine, where the track bends over the three-armed angular support X (Fig. 5), and starts downward. Just below the hood X containing the aforesaid three-armed, angular support X5, there is shown, in the same figure, (Fig. 5), a pusher rod OJ which acts like the above-described rod O8 to push the bottles out of the carrier buckets. As the bottle emerges finally from its bucket, it slides onto a short, slightly inclined; chute W10 (see Figs. 2a and 2b, Sheet 2, also the plan view in Fig. 4) which is normally stationary.

The lower ends of the chutes W10 are supported upon a shaft Z10 which is supported at its ends in the respective side members of the frame of the apparatus and the shaft Z10 therefore forms the pivot about which the chutes W10 may oscillate.

From chute W10 the bottle slides onto a second chute W20 which tilts up at itsfront end, as shown in Fig. 2b, and deliversthe bottle into a standing position on topof an auxiliary transversely moving chain-table Q10. The bottles are stopped from falling off the chain-table Q10 by,l

a vertical board V10 which (as shown in Fig. 1 and Figs. 2 and 2b and, in. plan, in Fig. 4) extends across the line of travel of the tilted-up moves, in that Fig. 4, from left to right.

also pinned to shaft I'I.

bottles and parallel to the edge of the table Q10. This board V10 is secured to pivoted arms V120 and restrained by a spring V11 (see Fig. 1). The bottles have now arrived at the chain-table Q10 (see Fig. 4) which moves from left to right (looking at the machine from its entry end, which is at the right of Fig. 4), and carries the bottles to the auxiliary longitudinally-moving chaintable Q2, shown at the top of Fig. 4, and there 'Ihis chain-table Q2 brings the bottles to the delivery table X20 which. stands at the right of the entryconveyors in Fig. 4. Thus the bottles, which were rst applied to the entry conveyors, are finally delivered on the table X20 at the same end of the machine at which they entered. In the meanwhile they have encountered the soaking operation in the bottom tank, have been scrubbed, rinsed and drained, and finally are brought to the delivery table X20, located right beside the entry-conveyor, where they rst entered the machine.

I will now describe the motive apparatus, which has kept the bottles moving along the above described course, and, finally, the safety provisions for stopping the machine in the event of a mishap to one of the bottles in its progress through the several operations.

The prime mover is a motor, preferably an electric motor, M (shown at the upper right in By a belt M2 the power of motor M is transmitted to a driving pulley M1 on the main shaft 2. This power plant is located in the open space between the horizontal soaking tank below it and the horizontal casing above it in which the l bottles are rinsed and drained after their scrubbing on the vertical run of the main conveyor. Main shaft 2 drives the sprocket chains M3 and M1 (Fig. 12).

The chain M3 drives the shaft I of a pump S100 (also shown in Fig. 3 at the extreme right), while the chain M4 drives shaft 3 which is the brush-n operating shaft (see also Fig. 3). The Worm on shaft 5 is driven from the aforesaid main shaft 2 through the gearing 50 (as shown in Fig. 5) and drives a transverse shaft 6 from which the chief movements of the machine are derived. Thus (referring to Fig. 5) on the said shaft 6 is a large wheel 'I that contains a. cam track 8 in which track runs a roller 811. This cam B gives a reciprocating movement to the parts ahead of it, whereas, the movements of the parts behind it have, up to this point, been rotary. The aforesaid roller 3 is mounted on a link III which, at its left end, reciprocates a lever-arm II and at its right end reciprocates a lever-arm I2. That reciprocates push-off pusher O9.

Thesaid lever-arm II gives several required reciprocating movements. By means of the link I3, it reciprocates five upright lever-arms which center on the cross shaft I`I at the bottom of the machine in Fig. 5. For a more complete showing of these five lever arms, it becomes necessary to turn to Fig. 9, where, of said five lever-arms, the two outer ones, I5, I5, are pinned to shaft I1 and move therewith, as does also the center arm I 6 But the intermediate arms I4 are loose on rthe shaft IL The two outer arms I5`are respectively jointed at their outer ends to the rods O4 which extend to the rear end of the machine (as appears in Fig. 3) Where they are joined to the cross bar T20 (see Fig. 6) which carries Vthe four pusher rods Oa that serve to eject bottles into the scrubber from the carrier buckets to permit the scrubbing operation. The

stroke of the aforesaid rods O'1 and O8 together with the cross bar T20 is determined by the oscil-` lating stroke of the aforesaid shaft il to which the lever arms I5 are likewise pinned. The contact lever arm I6, also pinned to shaft I'I, is the intermediate lever-arms I4, which are not pinned to shaft I'I, are operated in one direction, i. e., to the right in Fig. 5, by a strong spring Q30 anchored at Vits right end to the link I3 which is jointed to the aforesaid cam-operated arm I.

So when the arm II, by its link i3, pulls positively on control lever arm I6, pinned to shaft 'I to operate that shaft, it also 'exerts a yielding pull through spring Q30 on the intermediate leverarms Irl which are not pinned to shaft I 1. The arm It is provided with a boss I6' as shown in Fig. 5` and it is to this boss I6 that the link I3 is attached. When thus spring-pulled, a stop Ill which forms a cross connection between the arms I4 abuts against the said control lever-arm I5. At their upper ends the aforesaid lever arms It (see the right-hand end of Fig. 6) are conmoved by the aforesaid lever arms I4 to the left (see Fig. 3) against the force of spring W50 and is itself connected to the mouth piece S14. When a bottle is pushed out of the carrier for scrubbing by the aforesaid pusher O0, it engages the mouthpiece S1*1 and moves lit back against the said spring W50. Conversely the mouth-piece S14,

when worked by lever arms I4 acts to push the bottle back intothe carrier after the scrubbing.

The movement of the lever arms I6 is positive in, accord with` the operation of the link I3, whereas the movement of the lever arms I4 lags somewhat during the tensioning Aof the spring Q20.

y Therefore the bottles as they leave the cells of the conveyor are guided by the mouthpieces S11 before the mouthpieces are actually moved by the lever arms I4. In the event of aofailure of the bottle tor reenter the carrier cell or bucket D12 the spring W50 will yield and ultimately the aforesaid sleeve V25 will hit a push button W20 and cause the machine to stop. 'I'he stopping can also be caused by pressing manually on v the button W22.

lAlso from the aforesaid lever-,arm II extends (see Fig. 3) leftwardly and upwardly a rod 26 that 'goes to and operates the-above-described bottle-straighteners G10.

We may turn next to the work performed by the lever-arm I2, which, like said lever-arm II, is reciprocated by the large cam 8. As appears in Fig. 5, lthis lever-arm I2 is jointed at its lower end to the left end of the aforesaid push rod O which performs at the front end of the machine the same function that is performed by rod O at the rear end. That is, it pushes the bottles out of the vertical line of buckets or carrier cells of the main conveyer at the front of the machine. `At this front end it pushes them out onto the aforesaid chute W10, preparatory to their progress to chute W by which they'are tilted into upright position. Leverv I2 and pusher rod O0 appear in Fig. 2, as well as in Fig. 5. 0n the same center 40 with lever arm I I is one of the sprocket wheels driving the main conveyer belt, and, as appears in Fig. 3, the shaft 40, which carries the said sprocket wheels 50 is driven intermittently vby a stop-gear |00 driven by a gear 20|) on the aforesaid shaft I5. This explains the intermittent travel of the main conveyer.

The chutes W20 that tilt to upright position the outcoming bottles, are worked by a rock-shaft J2,'in Fig. 1, which also. works the bottle-follower J1 aforesaid. This shaft J2 (as best appears at the right of Fig. 85 and in the upper left of Sheet 4) is oscillated by a short lever J10 and the cam J15 on the shaft 4. Shaft 4 is driven by bevelled gears from the main shaft 6 (see also Fig. 4), and, by a chain J15 driven by sprocket Wheel lJ11, drives the shaft I8, which, in turn, operates the conveyer Q2 through the gearing K10, K1; The oscillated shaft J2 is connected (as shown in Fig. 4), by a rod 29 to the shaft J2 of the tilting chute W20. The Worm on shaft I8 and the worm wheel on shaft comprise power connection between shaft I8 and the carrier E2.

The aforesaid guard-board V10 which is mount-l ed on the arms V120, has adjustably connected to it the rod Z40 (Fig. 20) which operates the safety stop Z50 through the link Z51 and shaft Z10. Thus if the bottles crowd too numerously on the conveyer- Q10 they will push against the guard-board V10 and stop the machine. The arms V120 are attached to a slide-V121 upon rod Z40 and the slide V121 is adjustable on the rod Z40 under the control of a bolt V122 extending through an apertured ear V123 against which a wing-nut V50 advjacent end 45 of the link Z40 upon the bolt V122 is caused to, bear by reason of'a spring V11 extending between the slide V121 and a point of attach-y ment upon rod Z10 as shown clearly in Fig. 21-

What I claim as new and desire to secure by Letters Patent is:

1. An automatic bottle-washer including a traveling bottle carrier mounted to follow a substantially rectangular path, and provided with spaced groups of cells arranged side by side, a brush-belt mounted within the space encompassed by said carrier to follow a path at right angles to the lpath of travel of the carrier, means for thrusting bottles from a group of cells onto the brush-belt for a scrubbing operation, means for returning said bottles to cells on the carrier and a separate belt positioned to press the bottles upon the brush-belt.
