This invention relates to bottle washing machines. 7

Objects of this invention are to provide a bottle washing machine in which an endless 6 conveyoris provided for the bottles and is given a step by step motion to advance the bottles and cause a dwell of such bottles to occur over the interior spraying means, to provide a novel feed for this type of con- 10 veyor which will engage the conveyor at a plurality of spaced points on opposite sides thereof and will simultaneously impart motion to the conveyor by force transmitted to the v conveyor at these points, which will prevent binding of the conveyor at any portion thereof, and to provide mechanism for accomplishing these functions which is of sturdy, strong and simple design.

Further objects are to provide a plurality of dogs for engaging the conveyor at separate points, to provide an abutment for each of the dogs which will take the strain off of their pivotal connection with the advancing means, and to provide a construction of dogs which will not swing past dead center.

Further objects are to provide a bottle washing machine in which provision is made for collecting the labels'in a suitable recep tacle, in which means are provided for pre- 2 venting the labels from clogging the machine and preventing the return of the cleansing liquid to the reservoir, in which accumulation of dirt in the spraying means is prevented, and in which means. are provided for withdrawing the cleansing liquid from the reservoir and returningit thereto without causing undue agitation of the liquid in the reservoir.

Further objects are to provide a bottle washing machine in which the conveyor is so constructed that it will hold a plurality of bottles in closely spaced relation and will thus occupy a minimum of-room.

Embodiments of the invention are shown in the accompanying drawings, in which 4 Figure 1 is a plan view of the bottle washing machine such view being partly insection and showin the machine with the con W or removed or the sake of clearness. igure 2 is a fra entary transverse sectional view such view corresponding to a section on the line 2 2 of Figure 1.

he upper spraying means for the bottles may be of any desired type and has been omitted from the drawings for the sake of 'clearness, as such means need not be specially constructed to cooperate with this machine and, as stated, consequently any satisfactory or usual type of upper sprayingmeans may be employed.

The machine comprises a conveyor composed ofa plurality, of individual links 1 (see Figure 4) which are provided with a plurality of hot le holders 2. These links each carry aft eir outer ends a roller or wheel 3 provided with an inner flange 4. The inner ends of these links are provided with'tra'nsverse portions 5 which are pivot ally joined, as shown in Figures 2 and 4, preferably by means. of interlapping lugs and pintle pins 7-. These links are each provided intermediate their ends with transverse abutting arms 6 which, whenthe links occupy. the straight portion of the raceway,

are a apted to contact and to form in effect a solid straight conveyor. However, at the terminal portions, the links pivot above the pintle pins 7 and swing in a semi-circle from one straight portion to the other straight portion asclearly shown in Figure 4. Each engaged by the driving dogs hereinafter de; scribed. 1

The conveyor is carried upon parallel -of these links is provided'with an upstand- I ing lug or shoulder 8 which is adapted to be" thetracks comprises an outer rail 9 upon which the rollers 3 are adapted to travel,

and an inner rail 10 upon whichthe inner portions of the links are adapted to slide,

such inner portions being provided with downwardly extending lugs 11 (see Figure 2) .which, together with the inner flange 4 I as of "the rollers correctly position the links. The outer rail terminates adjacent the ends of the machine, as shown in Figure 1, and a pair of -flat semicircular portions 12 are provided and are adapted to support the anges 4 of the rollers while the links make these half turns.

The feeding mechanism for the conveyor d directly rality. of members '16 which are secured thereto by means of set screw 17 (see Figures 4, 6 and 7). Each. of the members 16 carries a dog which is provided-with a hub portion 18-secured to the upstanding ears of the member 16 by means of a pintle pin 19. The dogs are each provided with an outwardly projecting portion 20 which, as 1 tions and'is at all times exactly equal so that shown in Figures 6 and 7, gradually slants upwardly towards one end, Adjacent'this end of thedogs, the members 16 are provided with abutments 21 which are adapted to contact with the outwardly project ng from Fi' re 1 that a plurality ends is prevented portions 20- and to thus relieve the pintle us The dogs are each provided with an inwardly prcijecting ear 22, which, as may be seen from igure 6-, is adapted to en age the portion 16 and to prevent the dog rom bemg rocked past dead center. The inclined portions 20 of the dogs are ada ted to ride over the lugs 8 of the links of t e conveyor and the dogs upon the reversemotion of "the rods 13 and 14, are. adapted to engage such ears 8 and to advance the conveyor in a step by step manner. It is to be noted provide for each of the straight stretches and that binding of the conveyor at any portions of the strai ht stretches or at their Ty this construction and distribution of driving by this adequate force. i

In bottle washin machines as heretofore constructed, difiicu ty has been experienced due tov the unequal corresponding motions ofthe oscillatory rods at different points in their travel. wholly avoidedby the particu ar driving meansnow to be described. This driving means comprises "a pinion 23 (see Figure 1) which is 'dlysecured to a vertical shaft 24and mes ice with racks 25 and 26 carried by' the rods 13 and'14, respectively. The shaft 24 is given a rocking or partial rotary 19 of the major portion of the stresses to the electric motor of dogs are This defective o erat'ion is motion by means of a crank 27 secured thereto, as shown in Figure 5, and operated by means of a pitman 28. This pitman is con-' nected to'a smaller rotary crank-29 which is driven by means of a worm wheel 30 and worm 31. The worm 31 is rigidly secured to a horizontal shaft 32 which, by means of av clutch 33, is drivenfrom the pulley 34.

This pulley may be belted to any suitable source of power, for instance to a small pulley 35 show-n in dotted lines in Figure 5 and carried upon the shaft 36- (see Figure driven by an electric motor 37.

The clutch 33 is adapted to be'operated in any convenient manner as by means of a link 38 operatively controlled by oscillatory arms 39' projecting outwardly upon each side of the machine adjacent the forward end thereof.

The feeding mechanism, it will be seen, transforms the rapid rotary motion of'the motor into a rocking motion of the pinion 23 and this pinion transmits reciprocatory motion to the longitudinally extending bars 13 and 14 through the medium-of the racks 25and 26. It is to be noted that displacement of the rods 13 and 14 from their neutral or middle position isin opposite direcno binding of the COIIVBYOI will occur at any .point in its length.

which passes through the front vertical partition 42 of the reservoir and into the inlet portion of the centrifugal pump 43. This pump is directly connected .37, as shown in Figwe 10, and it is to be noted that the pump and motor are set within the outline of the machine and. thus do not require additionalwidth for the machine. The outlet portion 44 of the pump communicates with a fitting Q 45. such fitting being bolted through the side walls of the machine to the inlet fitting 46 of the lower header 47, as shown in Figures 1 and 10. The header 47 is provided with a plurality of upwardly directed nozzles 48' (see Figure 2) which projects streams water upwardly into the inverted mouths of ure 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 at one end thereof and sweeps continually around the header thus carrying with it, and discharging from point to point, any dirt that may be carried by the water,

the bottles 49. It is to be noted from Figvides a sheet-like streamof returning water materially reduced.

shown in Figure 3, to provide a basket with per header'or spraying means is also provided .but is not shown in the drawlngs as this upper spraying means may be of any and downwardly slanting deflector plate 53 is provided and is equipped with an upturning ledge 54 at its lowest end. This plate proand the led e prevents the stream from ac uiring sue velocity as to stir up the liqui in the reservoir but allows the liquid ;0 flow into the reservoir with its velocity It is necessary, as

a high rear wall 55 so as to insure the retention of any material washed downwardly from the screen 51. It thus becomes necessary to provide additional means for per-- "walls of the machine.

mitting the ready removal of the screen. As may be seen from Figures 3 and 8, the screen 51 is carried by a reenforcing frame work 56 which is slidably carried within side channels 57 pivoted, as indicated at 58, to the side In this way, the screen may be readily removed by rocking the channels 57 upwardly until the line of such channels is above the rear of the basket Q 55 and of the adjacent portion of the machine. When in this osition, the screen may be readily slipped f iom the, channels and may be cleaned,-of course, it is understood that the flap or cover 59 at the rear portion of the machine (see Figure 3) is readily removable to provide access to this portion of the apparatus. If desired a spring latch 56 may be carried by the, frame 56 and contact with the basket 52.

It fre uently happenst-hat in bottle washing inac ines the labels clo any screen mechanism that may be provi ed. This defeet in the operation of the machines, as

heretofore constructed, is wholly overcome in the practice of this invention by providing a wiper adapted to travel back and forth across the screen, and .to wipe the labels 7 rearwardly therefrom. This wiper consists of a pair of. side members 60' adaptedto travel upon the channel members 57, as shown in Figures 1, 3 and 8. These side members are connected by transversely ex tending bars 61, so that, in effect, a crosshead is formed. A flap consisting of a main bod portion 62 and a rubber or other strip 63 see Figure 3) is pivotally mounted adjacentits upper edge between the end mem the pitman does not press downwardly upon the pivotal joint with the flap 62. This truck is connected by means of a short link 68 (see Figure 3) with the lower end of a level 69 which is pivotally carried, as is indicated at 70, by a stationary portion of the machine body. The upper end of the lever 69 is connected by means of a link 71 with a bracket 72 rigidly secured to one of the oscillatory rods, for instance the rod 13.

It will be seen, therefore, that as the rod 13 reciprocates, the lever 69 will be rocked.

back and forth between its full line and dotted line positions, indicated in Figure 3,

and consequently the pitman 64 will be drawn back and forth. When the pitman is drawn inwardly the flap 62 is raised by rocking it about its pivoted point, as indicated in dotted lines in Figure 3, thus causing its -.upper eiid to contact with the stop 77. Thus while the cross head is being retracted. the flap is in elevated position and does not draw "the labels or trash inwardly along thescreen 51. However, when outward motion is imparted to the pitman, the flap is immediately rocked downwardly and its rubber or other lip 63 wipes outwardly across the screen 51 and thus wipes or pushes the labels and other trash from the screen into the basket 52. When the flap is rocked downwardly into its full line position, itsupper end contacts with the stop 78 thus 'reventing further rocking motion of the ap. In this way clogging of the screen mechanism is wholly avoided by this invention.

The modified form of link for-the conveyor,is illustrated in Figure 9 of the draw ings. From this figure it will be seen that three bottle holders, indicated at 7 3 7 4 and 75, are provided and are arranged at the apexes of a triangle. These bottle holders are joined by'diagonally extending connecting bars 76 which form an integral portion of the links. Otherwise-the links illustrated in Figure 9 are similar to those previously described. It is to be noted from this lastdescribed construction that three bottles may be held by each link without" increasing the width of the link over that necessary for 'holdin two bottles.

' It w1ll thus be seenthat a bottle washing I machine has been provided in which uniform motion is given opposite ortions offthe conveyor at. widely space points. It will I further be "seen that all strains tendin' to' cramp or bindthe-conveyor are thus avoided and that a smooth and re ar 0 eration of the machine results. -It tort or be seen that by the peculiar construction of dog and the supporting structures therefor, that stresses are primarily borne by the abut- ,ment and are not transmitted to the pintle pins of the dogs. It is to be noted also in connection with these dogs that there is no danger of their being thrown upwardly beside of the channels 57 as shown in dotted lines'in Figure 8.

It is to be particularly noted that the construction of this machine is-such that a minimum of width is required and that the machine, as a whole is self-contained.

Although a few forms of the invention have 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. a
