Fig. 15 is a side elevation of the modified driving mechanism for automatically transporting the admitted bottles through the washing and rinsing cycle, twice before delivering them from the machine.

Referring specifically to Figs. 1, 2 and 5' of the drawings, the improved milk bottle washing machine comprises generally a main soaking, washing and rinsing casing 2 resting upon adjustable supports I0 and forming a housing for an intermittently movable endless series of bottle carrier pockets 3; and an auxiliary pre-rinsing casing 59 also resting upon supports l0 and associated with the front of the main casing 2, the casing 59 providing a, support for the bottle supply and discharge mechanisms.

The lower portion of the main casing 2 provides a basin 2'! for hot caustic soda or similar solution, and each of the side walls of the casing i '29 in inverted position.

from the draining bottles to the basin rails comprising lower horizontal rails 9 located below the liquid in the basin 2?, upper rails 29,

82, located above the lower rails, an adjustable.

curved rail 18 connecting the rear ends of each set of lower and upper rails, and a fixed curved rail 28 connecting the front ends of each set or lower and upper rails. The rear end rails l8 are interconnected by cross bars I69 as shown in Figs. 9 and 10, and are swingable about lower pivots 68 by means of an adjusting screw 65, being guided near the top by means of pins 55 secured to the casing 2 and cooperating with slots 61 in plates secured to the rails. A plurality of plates 59 extend longitudinally of the machine between and beneath the lower rails 9, and between and rearwardly of the end rails 18, the plates 69 serving to retain the bottles within the inverted pockets 6. The forward portions 82 of the upper rails 29 are inclined for a considerable distance for the purpose of insuring complete drainage of liquid from the bottles prior to delivery'thereof from the machine.

The endless series of bottle carrier pockets 3 are formed of wire, each pocket comprising a wire ring and a plurality of substantially straight wires extending laterally away from the ring and interconnected to provide a bifurcated bottom. A number of the individual pockets 3 are secured to each other as shown in Figs. 3 and 4, to form transverse groups, the ends of the carrier frames 23 being attached to end links I. The successive links 1 are united by means of pins with which the carrier rollers 5 are rotatably associated. The carrier rollers 8 engage the rail sections 9, 29, E8, 28, and the links 1 together with their pins, form an endless conveyor chain for the pockets 3. The machine preferably embodies an odd number of groups of pockets 3, there being sixty nine groups or pockets to each endless series in the washer herein disclosed.

Located within the casing 2 above the basin 2'! and between the lower and upper rails 9, 29, is a series of reservoirs or basins l4, l5, l6 having headers provided with transverse rows of spray nozzles 39, Si, 82 of ordinary construction, located thereabove and adapted to deliver cleansing liquid into the bottles as they advance along the horizontal portion of the upper rail A downwardly and rearwardly inclined drainage plate I? is disposed beneath the inclined rail portion 82 and spans the space between the side walls 'of the casing 2, the plate I! serving to return water l6. The nozzles 39, 3! are supplied with suitable washing liquid by means of pumps I30, l3! respectively of well known construction, having their inlets connected with suction casings ll, 63, and removable plates 64 permit inspection of the mechanism within the main casing 2. The suction casings ii, 65 are of like construction as shown in detail in Figs. 11 and 12. The side wall I! of the main casing 2 has openings therein which connect the basins l4, l5 with the casings ll, 63 respectively, some distance below the tops of the casings H, 63. A filtering screen 16 divides each of the suction casings ll, 63 into a receiving compartment which is in open communication with the corresponding basin l4, l5, and a discharge compartment communicating with the pump inlet through a pipe 13. The screens 16 extend to the upper ends of the casings ll, 63,- and each of these casings is provided with a drain l4 and with an overflow l2.

The bottle supply mechanism is clearly shown in Figs. 2, 5, and 6, and comprises a transverse group of bifurcated receiving pockets 26 movable from upright to horizontal position and vice versa; a tiltable plate 44 movable from inclined to horizontal position and vice versa; and, a series of push arms 46 and a simultaneously operable push bar 42 for ejecting the bottles from the pockets 2;] onto the plate 44 and for sliding other bottles from the plate 44 into the adjacent pockets 3. The receiving pockets 29 are oscillatable about a horizontal axis by means of a gear segment 56 which meshes with a gear segment 48. The segment 48 is secured to a transverse shaft I48 which is rockable by means of a bell crank 41 one arm of which is pivotally associated with a connection 46 and the other arm of which is likewise associated with a connection 52. The rear end of the connection 46 is pivotally associated with one arm of a bell crank l2 the other arm of which is provided with a roller cooperating with a groove in the cam 5. The tiltable plate'44 is oscillatable from inclined position as shown in Fig, 5 to horizontal position in alinement with the pockets 20 as shown in Fig. 6 and vice versa, by means of a pair of levers 85 cooperating With links 5| secured to plate carrier arms 49. The plate 44 is preferably fins or plates forming grooves for holding the bottles in proper position. The lower ends of the push arms 49 are adjustably attached to a cross bar I40 secured to actuating levers 39, and the upper extremities of the push arms are movable through the bifurcations of the pockets 26. The cross bar I46 is operatively connected at its opposite ends with the push bar 42 by means of connections 4! and arms l4], the latter of which are rigidly attached to the upper ends of the end levers 39.

A curved stop plate 45 having openings 8[ through the lower portion thereof, extends along the path of travel of the rear end of the plate 44, and a pro-rinse supply pipe has orifices therein formed to direct jets of water through the stop plate openings 8! and into the open ends of the downwardly tilted bottles resting upon the inclined plate 44. A resiliently supported guide plate 43 located at the upper end of the stop plate 45, is supported from the casing 59 by means of springs 51 and hinges 56, the tension of the springs 51 being adjustable by means of nuts 58, see Fig. '7. The guide plate 43 serves to properly admit the bottles regardless of their size, to the pockets 3, without breakage.

The bottle discharge mechanism is likewise clearly disclosed in Figs. 2, 5 and 6, and comprises a series of bottle ejectors 54 movable through the pockets 3 while they are horizontally disposed; a series of bottle receiving and righting members 2|; and a transversely movable final conveyor IQ of ordinary construction. The ejectors 54 are carried by a transverse rod which is movable along arcuate slots 55 in the sides of the main casing 2, by means of levers 3 one of which coacts with a swivel block 38 as shown in Figs. 5, 6, 13 and 14. A bell crank lever 34 has one arm provided with a roller cooperating with a groove in the cam 25, and has its other arm secured to an end of the bar 35 which extends freely through an opening in 'the block 38. Springs 36 embrace the bar 35 on opposite sides of the block 38 and engage adjustable nuts cooperating with the bar to vary the spring tension. A connection 3'! has one end pivotally associated with the block 38, and has its opposite end attached to the lever 39 which actuates the push arms 40. The bottle receiving and righting members 21 are adapted to be swung about a horizontal pivot, from inclined position as shown in Fig. 5, to upright position as shown in Fig. 6, by means of a lever 53. The swinging end of the lever 53 is connected to an arm of the bell crank lever 41, by means of a connection 52.

The mechanism for driving the machine consists of an electric motor 4 mounted upon the main casing 2 and controllable by means of a switch 15. The motor 4 is connected through a flexible coupling 6!, to a constantly rotating counter shaft which is interchangeably connectible by means of a manually operable jaw clutch 22, with high and slow speed gearing 62 of well known construction. The speed change gearing is operatively connected to cranks 83 in Figs. 1 and 15, or with cranks 68 as in Fig. 5, which cooperate through connections 84 with intermittent grip devices 6 comprising hooks 23 formed to grip and to advance the successive rollers 8 along the rails 23. Motion is also transmitted from the motor 4 through a driving chain 26 to a transverse counter shaft 33 to which the cams 5, 25 are secured. switch '35 which controls the circuit of the motor 3, is also operable by means of automatic stop mechanism such as shown in Fig. 14. This mechanism comprises a latch 78 operable by abnormal displacement of the swivel block 38, a latch plate 1'! mounted upon a pivot 98 supported by the casing 2 and cooperating with the latch 18, a spring 79 for swinging the latch plate downwardly about its supporting pivot 93 when the latch 13 is released, and a rod 16 connecting the plate 17 with the lever of the control switch 15.

While the carrier pocket advancing mechanism of Fig. is adapted to intermittently advance the pockets a distance equal to the space between the axes of successive rollers 8, the mechanism of Figs. 1 and is constructed to intermittently advance the pockets double this distance in order to cause the bottles to be transported twice through the machine before final discharge thereof. The cranks 83 and the grip devices 5 of this modified mechanism are formed to produce double the throw of the pawls or hooks 25 in the mechanism of Fig. 5, and such operation combined with the odd number of pockets 3 in each series, produces the desired result of causing the rinse spray nozzles 32 to cooperate only with alternate pocket rows just prior to final discharge of the washed bottles. With the machine properly designed, the cranks 83 and devices 6 may readily be substituted for the single throw cranks iii? and devices 6 of the machine disclosed in Fig. 5 at the option of the operator.

During normal operation of the machine, the dirty bottles are placed in the receiving pockets 29 when positioned as shown in Fig. 5, in substantially upright position while the motor 4 is operating continuously. Periodically, the pockets 20 are swung rearwardly to horizontal position as shown in Fig. 6 whereupon the push arms at are moved through the bifurcations of the pockets and eject the dirty bottles therefrom onto the plate l with their open ends pointing toward the machine. After the bottles have been thus positioned upon the plate 44, the

The-

pockets 20 are returned to bottle receiving position as shown in Fig. 5, and the plate 44 is tilted downwardly thereby causing the bottles to slide toward the openings 8| in the stop plate and to receive the full force of the pre-rinsingjets discharged from the pipe 80. The plate 44 is eventually again returned to horizontal position as shown in Fig. 6, whereupon the push bar 42 becomes effective to slide the pre-rinsed bottles from the rear end of the plate 44 over the guide plate 43 and into the horizontally disposed group of pockets 3 positioned with respect to the plate 43 as shown in Figs. -'7 and 8. Simultaneously with the removal of the pre-rinsed bottles by the bar 42, the push arms 40 are ejecting other dirty bottles from the pockets 20. The intermittent grip device 6 urges the loaded bottles 3, step by step, along the successive rails 28, 9, I8, 29', 82. As the bottles travel through the basin 27, they are subjected to the soaking a;

and washing action of the hot caustic soda solution. While travelling along the end rail I8, the bottles are inverted and the caustic soda solution is delivered therefrom into the basin 21. The bottles of washing and rinsing liquid delivered from the nozzles 30, 3!, 32 during their travel along the rails 29 and over the basins I4, I 5, [6. When the double throw cranks 83 of Figs. 1 and 15 are used, the pawls 28 rows of pockets 3 and with the several spray means, to cause the washing liquid sprays from the nozzles 30, 3! to be delivered against the interiors of all of the bottles while traversing the upper conveyor stretch, and to cause the rinsing liquid sprays from the nozzles 32 to be delivered only against alternate pocket rows which have passed through the machine two successive times, thus insuring thorough washing and final rinsing. inclined rail sections 82, the bottles are tilted thus causing the liquid remaining therein to flow toward the lower inner side surfaces thereof and to be quickly and effectively drained from the inverted bottles, the to the basin l6 along the drain plate l1. The pockets containing the finally washed and rinsed bottles are eventually again brought into horizontal position at the front of the machine, whereupon the ejectors 54 are brought forward through the bottoms of the pockets 3 and push the clean bottles from the pockets upon the members 2|, while these members are positioned as shown in Figs. 1 and 5. The members 2| are subsequently swung forward to upright position thereby setting the clean bottles upon the chain conveyor i9 which delivers them from the machine.

If an abnormal condition of operation such as improper insertion of a bottle, arises, the automatic stopmechanism of Figs. 13 and 14 becomes eifective to throw the switch and to stop the motor 4, thereby avoiding damage to the wire pockets and other relatively frail parts of the machine. This stop becomes efiective if the normal movement of the swivel block 38 is obstructed in any manner, thereby causing the latch 78 to release the latch plate H and permitting the spring '19 to become effective to throw the switch. For example, if the forward motion of the ejector 55 and of the arms l3 which carry the same, is interrupted as by one or more bottles becoming jammed within the carrier pockets 3, and the bell-crank i i to which the rod 35 is attached, continues to move, the 755 are subsequently subjected to jets z.

cooperate with the When passing over the drainage liquid returning latch 18 will automatically be released from the plate to thereby stop the machine until the jammed bottles have been removed.

From the foregoing description, it will be apparent that the bottles are automatically successively pre-rinsed, washed, finally rinsed, and removed from the machine at the loading end thereof. By pre-rinsing the dirty bottles, the liquid in the basin 2! may be maintained relatively clean for a long period of time. The pump suction casings ll, 63 and the strainers therein, insure a relatively clean supply of liquid for the nozzles 3%), 3i, and the inclined rail sections 82 provide for effective removal of water from the bottles prior to their delivery from the machine. The mechanism of Fig. cooperating with odd numbered series of pockets 3, permits automatic application of a double wash without reducing the capacity of the machine, and the drain plate ll besides conducting the drainage liquid to the reservoir l6, prevents the fumes from the basin 21 from reaching the mo- 7 tor and gearing. The machine while being relatively simple and compact, has large capacity and the adjusting mechanism associated with the rear rails l8 enables maintenance of proper tension in the carrier chain. The intermittent grip mechanism eliminates necessity of using noisy sprockets, and the supply and discharge mechanisms operate to avoid breaking bottles. The. self adjusting feed plate 43 insures proper admission of the bottles to the pockets 3, irrespective of the size, and the pockets 3 may be readily formed at low cost, of standard wire.

It should be understood that it is not desired to limit the invention to the exact details of construction and operation herein shown and described, for various modifications within the scope of'the claims may occur to persons skilled in the art.
