BOTTLE-WASHING MACHINE.

To all whom t may concern v Be it known that I, CHARLES ALFRED EN- son,va subject of the King ofv Great Britain, residing at Vellington, county of Shropshire, England, have invented certain new and useful Improvements in Bottle-l/Vas'h ing vMachines, of which the following is a specification.

This invention relates to bottle-washing machines of the kind comprising a series of radially-arranged bottle-carrying arms, hinged to a central carrier or driving element to which an intermittent rotatory motion is imparted, and running upon a track or lrace of kcam formation, so that as the arms revolve the bottles carried thereby are immersed within the washing water contained within, a tank and are successively brought lto rest opposite one or more reciprocating fbrushes which are automatically operated'so as to scour the interior, or interior and exterior, of the bottles; the said carrier arms, after passing the vbrush or brushes, being caused by the cam track to rise and lift the bottles clear of the water.

In the previous arrangement the cam track was situated within the tank, carrier arms having rollers or bearers immersed within the water and vrunning upon the track; the pivots of the carrier arms being also situated within the water.

The principal object of the present invention is to vinsure that the bearers and, pivots or other working parts shall not be immersed in the water, softhat no corrosion of the working faces can take place due to any acids thatl may be present in the water; this obj ect being attained 'by kproviding the cam track above the surface of the water, the bearers preferably being carried lby extensions of the arms beyond the pivots, so as to engage beneath the Xed cam.

YOther objects of the invention are to improve and simplify the means for imparting the intermittent motion to the carrier; 'to provide -improved means for operating the reciprocating brushes so as to prevent damage occurring should the `brush meet with an obstruction on entering the bottle; to improve the arrangement of the brushes for cleaning-the outsides of the bottles; and Ato provide improvedmeans for rinsing-the bottles after `they have been removed from the washing water.

Fig. '2 is another section showing theV mechanism for use 'in connection with the rinsing of the bottles. Fig. 8 yis a plan of the machine. Fig. 4 illustrates a detail in connection with the valve used for controlling` the supply of water tolthe rinsing'nozzles. Fig. 'is alongitudinal section `through the brush carriage, showing'how y"the brush spindles are driven. Fig. 6 represents a cross-section on line m, Fig. -5. Fig. 7 is another cross-sec* tion through -thebrushes for theoutside of the Ebottles and through the guide rods of thebrushcarriage, showing'the latter in end elevation. "Fig. 8 shows a section taken on llne x1 Fig. 1, upon alarger scale, illustrating lthe Ipulley clutch andl worm driving mechanism. Fig. 9 Iis a -view of the intermittent driving gear 'for the rotation of the bottle carrier.

The improved Abottle-washing machine (see fFig. 1) comprises a central vertical standard 1fi-Xed within a hollow column or socket 2. A boss` 3, forming part of the rigid frame of the machine, has projecting therefrom a horizontal shaft 4 Aupon which is rotatably mounted a sleeve 5 having keyed ."thereupon a wormewheelv 6 driven from a `worm shaft 7 which is rotated by apulley 8 Vfitted with the usual clutch 9 and disengaging gear l() (see Fig. 8). The sleeve 5 carries a bevel ypinion 11 having only a single tooth (see Fig. 9) adapted :to engage with yandcrotate a Ahorizontal bevel wheel 12 having a series of gaps or spaces in its peripheryV which are engaged in turn by the 'singletooth Thebevel wheel 12 is keyedfto the boss '13 of the horizontal carrier disk f1.4 'free to turn about the shaft 1, and to which are hinged the rising and falling bottle-carrying arms 15. During one complete revolu'tion'of 4the pinion 11 the horizontal wheel 12 ismoved by the single tooth Athrough a space equal to the distance beinto which depend' the radially-arranged bottle-.carrying arms 15, said arms being pivoted at 17 5 (above the water level) to the edge of "the horizontal carrier disk 14; and

sition above the water (Fig. 1) or above the horizontal (Fig. 2), whereas when they cngage with the highest portion the bottles are wholly immersed in the water, and lie more or less obliquely (rightshand side of Figs. 1 and The weight of the bottles maintain the arms in engagement with the cam.

As the carrier arms15 are brought to rest by the intermittent drive, a pair of bottles come to rest opposite to a corresponding set of brushes (see Fig. 1). The brush gear comprises a reciprocating carriage or saddle 23 sliding upon guide rods 24 and carrying two brushes 25 adapted to be forced into the interior of the bottle. The carriage car* ries a pulley 26 (see Figs. 5 and 6) which is feathered upon a square or other driving shaft 27 supported by a fixed bracket 28. This shaft 27 has fixed to it a pulley 29 driven from a pulley 30 on the worm shaft 7 by a belt or band 31 passing around guide pulleys 32, 33, carried by suitable brackets.

The main pulley 26 upon the saddle drives, by means of a belt 34, the spindles of the two brushes 25 for cleaning the inside of the bottles. For cleaning the outsides of the bot-tles three concave revolving brushes 36 are employed (see Fig. 7 same being oarried upon spindles 37 arranged at right angels to the axes of the bottles and adapted to engage with opposite sides of the bottles, the middle one coming between the two bottles. The spindles 37 of `these external brushes carry at their upper ends pulleys 38 driven by a band 39 (see Figs. 3, 5 and 7 from a pulley 40 driven by bevel gear 41 from the main pulley 26.

The brush carriage 23 is moved so as t0 force the brushes 25 into the bottles by means of a. weight 42 which, by means of a cable 43 rotates a pulley 44 (see Fig. 1) mounted upon a spindle to which is fixed an arm 45 connected to the carriage through the medium of a connecting rod or link 46, so that as the weight descends the arm and connecting rod move the carriage forward and downward, causing the inner brushes 25 t0 pass into the interior of the bottles, and the revolving concave brushes 36 to pass over the outsides of the bottles. Should the4 brushes meet with an obstruction the descent of the weight 42 is arrested, no damage resulting as would be the case if the brushes were positively operated by means of a cam. To withdraw the brushes a horizontal cam 49 is fixed upon a sleeve 47 surrounding the upper part of the standard 1 and driven by a bevel wheel 48 on the sleeve 5. This cam 49 operates a sliding rod 50 having a pin 51 engaging a slot 52 in an .arm 53 fixed to the shaft of the pulley 44. The travel of the carriage can be altered to suit different sizes of bottles, by means of an adjustable screw stop 54. The end of the rod 50 adjacent to the cam carries a cage or frame 72 supported and guided in its reciprocating movement by the boss of the cam 49, as shown in Fig. 1. The said guide frame 72 carries a roller 73 with which the cam engages. The said cam is of the shape shown in Fig. 3, so that as the narrower part of the cam comes opposite the roller it allows the rod 50 to be moved inward by the weight until the stop 54 comes against the fixed part 74. By lengthening the stop 54 the amount of travel of the brush carriage is reduced.

In order to accurately center the bttles while the brushes are being passed into the interior, two centralizing forks 55 are provided slightly in advance of the brushes, these forks being carried on sliding rods 56 forced by springs 57 but which are moved back by the carriage, when the latter is fully withdrawn, so that the forks 55 'are just clear of the bottles. When, however, the carriage moves forward the rods 56, due to the action of the springs 57, follow the earriage movement until the 'forks engage with the bottle necks, thus centralizing said bottles. The forks are kept pressed against the bottle necks until the carriage on the return movement overtakes the rods and releases the bottles before the carrier arms 15 are moved away to bring a fresh set of bottles into position.

In order to effectually clean the bottoms of the bottles either fixed or rotary brushes may be employed within the tank.

On the withdrawal of the brushes the bottles which have been cleaned are moved forward into the position shown in Fig. 2, coming to rest opposite to a pair of nozzles 58 from which a jet of fresh water is directed l into the bottles for rinsing. The nozzles slide in housings 59 carried by brackets 60 on the fixed cam plate 21 and tend to be forced forward into the bottle necks by springs 61. They are adapted to be withdrawn by a lever 62 connected by rod 63 to bell-crank lever 64 actuated by a cam 65 fixed on bevel wheel 48. The said cam comes into action while the carrier arms and bottles are being moved through the interval necessary for the introduction of a fresh set of bottles before the respective brushes, when the cam allows the springs 61 to move the nozzles against the bottle mouths. A perforated pipe 66 sprays water upon the outL sides and endsof the bottles. A controllingv turns off the water owing to the pin 69 engaging with al secondl arm 7 0 on the valvek spindle. A pipe 71 leads from the valve to the nozzles.
