Application filed August at, 1920. Serial No. 6,70? K To all whom it may concern;

Be it known that 1, ELIAS ANDRnAsnN SoHMm'r, residing at No. 123 Vesterbrogade,

'1 Copenhagen, Denmark, have invented certain new and useful Improvements in and Relating to lt fachines for Washing Bottles, of which the following is a specification.

This invention relates to machines for washing bottles. I

The'object of the invention is to provide an improved machine whereby safe and perfeet cleansing of bottles may be efit'ected without the use of brushes or the like.

According to the invention the bottles after having been soaked and filled with warm water, are suddenly exposed to a blast of highly compressed air which ejects the water and impurities,whereupon the bottles are'again filled with warm water and finally emptled and'rinsed with cold water.

The inventionis illustrated in the accompanying drawings, according to one form of machine. r r p Figure 1 shows a vertical longitudinalsection of the machine on the line 1-1 of Figure 3.- r

Figure 2 is a horizontal longitudinal section on the line 11-11 of Figure l, 1

Figure 3 is a vertical section on the line 111-1][][ in Figure 1. l

Fig.- 4: is a horizontal section. on the line 4- 1 of Fig. 2; i

Fig. 5 is an elevation of the machine at the bottle receiving end;

Fig. '6 is an elevation. of the end of the machine from which the bottles are discharged; and,

Figs. 7 and 8 are top plan views of the a right and left hand portions of the machine,

respectively. I

Referring to the drawing, 1 is a tankin which is fitted an endless conveying band consisting ,of two roller chains 2 'and of a ftll jointed bottle conveyer mounted between the chains. =The conveyer consists of narrow.

pieces 4t hinged together by bolts 3and with funnel formed holes 5 for receiving the bottles.

The conveyer passes over a'chain wheel '6 at oneend of the tank 1 and over two chain wheels 7 and 8 n1ounted below each otherat the other end ofthe tank, the upper edge of the chain wheel 7 being higher than the upper edge of the chainwheel 6 in such way shaft 20.

At one end of the machine (see the left two armed lever 12, 13, the other end of which is fitted with a pawl 14 co-operating with a pawl disc 15 applied onthe shaft 16 of the wheel 7. I

The shaft 17 is rotated by means of a toothed gearing 21 from the main'shaft' 19 driven by a spur wheel 18 which shaft by another toothed gearing 22 turns-another on Figure 1) a tray'2 3 is fitted in such way that each time the' baihd is displaced, it will be turned from the position shown in Figure 1 into a'sloping position, whereby one row of bottles placed. with their necks fore most ,on the tray will glide into a" corresponding row of receiving funnels 5 in a link piece a. This movement of the tray 23' is due to a lever mechanism 24:, 25, 26, 27, 28 moved by the shaft 20. i

From the same shaft 20 a corresponding row of expulsion devices 33 is moved over.

a lever mechanism 29, 30,31, 32, which isfitted on a frame 341.

Outside these expulsion devices is a tray 35, which likewise can be tilted by a levermechanism 36, 37 which is moved fromra camdisc 38 on'the shaft. From ai compressor 39 with air tank 40, a pipe 4:1 conveys compressed air to a row of air nozzles 42.-

Theseare connected with the pipe llby air hose a3 and are fitted in sleeves 414:, which are lifted by the lever mechanism 4L5,

416 from a cam 50 on the shaft 20. [The conical lower ends 51 of the sleeves M in duev time by their own weight pass down over he bottles, and the nozzles 12, when pressed downto the position shown in Fig. 2 will enter the neck-of the bottle. Finally in the pipe systemy al, 413 a spring-loaded valve is fitted, which is not shown in the drawing but whichgfrom some moving member of ltlll the machine, for instance, the lever 45, is to their'plaoes, partly by spring 53, partly opened at the moment when the nozzles 42 by'a two- armed lever 54,55 moved by a cam have entered the bottles. 8-

The machine operates inthe following From the tray 35 when turned upwardin manner': i I an inclined posltion by the lever mechanism By the pawl 14 the cbnv y r' b d i 36, 37, the bottles will pass through guiding turnedin such manner that every other link grooves 56 down to the funnels of the rinspiece 4, each time the conveyor band stops, i g machine 49. will be just infront of the insertion slot 46 It is to be noted that instead of the arin the lefi; end of the machine, and th re b rangement described, a more simple maing an'odd number of link pieces 4 each link Chine can be used on the same principle of piece 4 Will only at every second turning of the invention, the conveyor chain being rethe band be in front of the said slot 46 placed by aisingle conveyor wheel arranged At the moment a link'piepe stops in front aim the simultaneous cleaning of one, two or of the slot 46*, the tray 23 will be tilted, the morebottles. outer end being swung upward by the lever Having now particularly described and connection, and in this way all the botltes ascertained'the nature of my said invention lying on the tray will glide down into the and. in What manner the sameis to be percorresponding funnels. formed,.I declare that what I claim is The bottles will now gradually pass 1.
