To all whom it may concern.

Be it known that l, HENRY F. STOCK, a citizen of the United States, residing at lvaukesha, in the county of TVaukesha and State of Visconsin, have invented certain new and useful improvements in Bottle ,Vashing and Soaking Machines, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates to bottle washing machines or the like, which are used for washing and soaking bottles, sterilizing bottles and similar purposes, and the object of the invention is to provide a simple machine which will convey bottles through a bath of liquid, the arrangement of the machine being such that the parts can be readily maintained in perfect operating condition and the bottle holders or retainers being constructed so as to avoid all danger of breaking the bottles.

Generally speaking, machines of the general type to which this invention applies, comprise a tank or receptacle for holding a liquid, and mechanism adapted to hold bottles and carry them into and through the liquid contained in said tank or receptacle.

The specific features of novelty presented by this invention will be specifically pointed out in this specification and claimed.

Referring to the drawings which aecompany this specification and form a part thereof, and on which the same reference characters designate the same elements in each of the several figures, Figure 1 illustrates in elevation, a bottle washing machine embodying my invention; Fig. 2 illustratel a vertical section on the line a. a of Fig. 1; Fig. 3 is a plan view of the machine; and Figs. 4 and 5 illustrate details of the hinge mechanism.

Referring specifically to the drawings, the numeral 1 designates a tank or receptacle adapted to contain the liquid in which the bottles are to be immersed, said receptacle being made for convenience from sheet metal and provided with a draw-oft1 pipe 2, and a manhole and cover 8, through which the interior of said receptacle may be cleaned. lNithin said tank is located a shaft L1, upon which are disposed two sprocket wheels 5 and 6, upon which are adapted to run, sprocket chains 7 and 8.

Above the machine is supported a shaft 9 provided with two sprocket wheels 10 and 11, which are placed the same distance apart as the sprocket wheels and 6 on shaft 4, and around these four sprocket wheels the endless chains 7 and 8 are adapted to pass in the ordinary way. To these endless chains 7 and 8 are attached the bottle receptacles 12, said bottle receptacles preferably inclining downwardly and inwardly on the charging' side of the machine, as clearly shown by Fig. 2 of the drawings.

rihe shaft 9 is supported by boxes 18 and which are slidably retained between guides 15 and 1G, which guides are preferably supported upon the top of the tank 1 by being bolted to lugs 17 and 18 thereon, though they may be supported in any other convenient or preferable manner.

rlhe boxes 13 and 14@ rest upon screws 19 and 20, which may engage with cross members 21 and 22 secured to said guides, or as is preferred and which construction is illustrated by the drawings, said screws may pass through nuts 23 and 24, which rest upon said cross members 21 and 22 immediately above apertures 25 and 2G therethrough, said nuts being prevented from turning by being seated in the recesses 27 and 28 provided in the tops of the cross members 21 and 22. rlhis construction is adopted because if the members 21 and 22 are ordinary castings, as will usually be the case, the holes or apertures and 2G may be formed by cores during the process of casting, thereby reducing the amount of machine work necessary to complete the apparatus.

By supporting the boxes 13 and 14 so that they are slidable toward or away from shaft 1, the endless chains 7 and 8 may be kept in Trl.

,perfect tension, and if it becomes necessary to dismantle the machine and reassemble it, the links of said chains may be readily removed either from the sprocket wheels of the machine, or the links may be disconnected from each other so as to remove the chains entirely from the machine. Another advantage of this construction arises from t-he fact that the sprocket chains wear more or less in use, and by the use of the screws shown or equivalent mechanism, the chains 7 and 8 may be kept taut.

lv/ilounted upon one end of the shaft 9 is worm gear 29, which is keyed to said shaft or otherwise secured thereto so as to rotate the same, and to rotate said worm wheel 29 the worm 30 is provided, this in turn being provided with a shaft 81 to which fast and loose pulleys 32 and 33 are secured, or said l long'itudinally of thc path which the bottles shaft may be provided with a single pulley, or any other means for imparting rotation thereto from some driving mechanism, this specific feature of the machine illustrated not being a part of my invention.

It will be evident by an inspection of Fig. 1, that if screws 19 and 2O were manipulated to move shaft 9 up or down, the worm wheel 29 would either crowd against the worm 30 or would be thrown out of mesh therewith, unless the worm 30 were to partake of the upward or downward movement of worm wheel 29 due to the manipulation of screws 19 and 20. This is an important part of my invention, and I provide an arrangement of parts by which worm wheel 29 retains its position with respect to worm 8O regardless of the manipulation of screws 19 and 20. The specific construction which I have adopted for this purpose comprises a bracket' 34 supported by box ll4 and provided with extensions 35 which are adapted to bear against the guides 16 to prevent rotation of said bracket with respect to said shaft, while permitting said bracket to be raised or lowered with said shaft. This bracket 34 is provided with boxes 36 and 37, within which the shaft 31 is rotatably supported. This part of my invention provides mechanism by which the endless chains 7 and 8 may be tightened or loosened, or the shaft 9 moved toward shaft t or away therefrom, without interfering with the rotation of shaft 9 by the driving means, which is preferably a belt engaged with either the pulley 32 or the pulley Located adjacent the discharge side of the machine is a tank or receptacle 3S, adapted to contain water, and hinged preferably to tank 1 by the hinges 39 is a receiving platform or board 10, normally disposed on an incline upon which the bottles are adapted to fall from the bottle receptacles and slide down into the water contained in tank 3S. This board 4L() is preferably covered with sheet metal 11, and at its lower edge itl is recessed slightly at 42 to admit the sheet metal extension 43, which is preferably slightly curved, as clearly shown by Fig. 2 of the drawings, so that the bottles will be delivered on to the surface of the water in tank 3S without undue or shock and without causing any particular splashing of the water.

The reference numeral 130 designates straps of iron or other suitable material, which are secured by rivets or other suitable fastenings to the board 10 and to a sheet metal extension 43, in order to provide su'liicient stiffness and rigidity for said sheet metal extension, but this stiffness or rigidity could be readily obtained by other equivalent constructions, as for example, by making said extension 113 from metal corrugated follow. The reference numeral 15:31 designates strips secured to said board L10 which serve to provide separate runways for the bottles, a separate runway being preferably provided for each one of the compartments of the bottle receptacles. The hinged fea.- ture of this receiving board, as it will be termed, is valuable because if this .machine is used for washing bottles, more cr less paper debris, as labels, ete., will separate from the bottles in tank 38 and collect in the bottom thereof, which can be readily removed by swinging said receiving board up out of the way on its hinges 39, as the bulk of the paper will collect in the corner #la of the tank 38, for the reasons to be now e plained.

The numeral 45 designates a standard provided with an aperture 1G through which a pipe 47 provided with perforations i8 may be inserted, it being understood that there is a standard Ll5 on each side of the tank 38, as fully disclosed by Fig. 3 of the drawings. This pipe 1-7 has one end closed by a plug 19, or the equivalent, and its other end is adapted to be attached to a flexible hose or the like. The purpose of this pipe to spray streams of water at an angle against the surface of the water in tank 3S, in order that a current may be established which will tend to move the bottles away from the receiving board to the farther end of the tank, so that as the bottles slide down the receiving board into tank 3S, the bottles which have preceded them will lave been moved away, so that no collision will occur and consequent breakage.

T have referred to the charging side of the machine and the discharging` side, and it is to be understood that by such expressions T mean the side of the machine where the operator stands to insert the bottles into the receptacles 12, and the side of the machine where the bottles are discharged by gra vity from said receptacle. lilach of these bottle receptacles is similar to each of the others, so that a description of one sullces for a description of all. Each bottle receptacle is formed of two sheet metal walls 50 and 51, which extend transversely of the machine and are united by end plates and 53. Each of the plates 50 and 51, are bent over, as at 541, 55, to form what might be terinet the bottom of the bottle receptacle, but these overturned portions 54tand 55 do not quite meet, leaving an opening in the bottom of said receptacle.

The members 50 and 51 are braced and strengthened by sheet metal braces 5G, which also serve to divide the bottle receptacle into separate compartments, each of which is adapted and intended to receive but a single bottle.

The numeral 5T designates a cover or cloesima sure for a bottle receptacle, said cover being provided with notches 5S through which when the covers are closed, the necks of bottles are adapted to extend provided the height of said bottles is greater than the depth of the bottle receptacle. This cover 57 is not hinged at the end of the bottle receptacle, as is the case with an ordinary box cover or the like, but is hinged to said receptacle at a point removed from its front end some considerable distance, as clearly illustrated by Figs. 2 and l ot the drawings.

Preferably there are two malleable iron hinges to each cover, the hinges being of the kind known as stop hinges, the member secured to the cover being provided with a stop 59, adapted to engage with the other member or element of the hinge to limit the extent to which the cover 57 can open. These hinges, as has been stated, are preferably made from malleable iron, and are secured to the bottle receptacle and the cover by rivets or in any suitable or preferred manner, and each hinge 'is preferably placed close to the end of its cover, and the part of the hinge secured to the cover is provided with an outstanding pin or projection 60, the purpose ot' which will be now explained.

Referring to Fig. 2 of the drawings, if the top of the upper sprocket wheel is turning from the righthand to the left, the covers 57 of some of the bottle receptacles will fall down by gravity, thereby giving l free access to the interior or" said receptacles.

rlfhis is the charging position of the receptacles, and the lett hand side of' the machine (see Fig. 2) is the charging side.

The bottles are inserted in the receptacles by the attendant when the covers are in the open position, and as the receptacles descend into the tank l, the projections (30 on the hinges of the covers engage with guides Gl suitably curved so as to cause saidvcovers to close and to retain said covers closed while said receptacles are passing through t-ank l, and until they are above the receiving board 40 on the discharging side of the machine, at which point the guides 6l terminate and the covers open by gravity and because of the weight of the bottles in the receptacles, and the bottles will slide out on to the receiving board 40 and down into tank 38.

As the receptacles pass on and up and around the upper sprocket wheels, the covers will close by gravity, and they would remain closed until they had passed around said sprocket wheel to some considerable distance. In order, however, that said covers may be positively opened, the secondary guides 62 are provided, which engage under the pins or projections G0, thereby raising said covers as the receptacles pass by said guides 62. The covers 57 are hinged to said receptacles at a point somewhat remote from the t'ront ends of said receptacles, tor the following` reason: It bottles are inserted in said receptacles which are ot' just such a lengt-h that the ends of the necks project out of said receptacles, if the covers were hinged directly at the ends of the receptacles, when the pins G0 engaged with the guides Gl the tendency would be to jam the covers against the necks of the bottles and break the covers or the bottles or both. TWith the construction adopted however, the covers are swung upwardly as well as toward the receptacle, so that with suc-h bottles as those referred to, the necks of the bottles will be engaged ordinarily by the notches 58 of the covers, and the necks of the bottles will be elevated by the covers into such a position that the covers can properly close.

While l have described in this specification and illustrated by the drawings accompanying the same, certain specii'ic embodiments orl my invention, I do not wish to be limited to the precise structural features shown by said drawings, but reserve the right to make alterations therein which fall within the scope of my invention and within the scope of the claims annexed hereto.

In order that the receiving board yl() may be swung up out of the way on its hinges 39, pipe t? may be \\fitlitl1?a\vn from standards Ll5 by simply removing it endwise toward the left hand (see Fig. 3), as said pipe is simply placed loosely within the apertures lo in standards a5.

find that it is an advantage to provide means at the discharge side of the machine to cause the covers of the bottle receptacles to be opened positively at the discharging point of the bottles, 'for the reason that. the hinges ot the covers may stick, owing to tight joints or slight inaccuracies ot' workmanship in fitting the parts, and it metals which rust or corrode are emplojf'ed, such as iron or steel for example, the parts of the hinges become more or less rusted after being used for a considerable period. rlhe positive means for opening the covers may be of any suitable or preferred character, and may be constructed either to cause the covers to be opened suddenly or slowly.

The means which l at present prefer tor causing the covers to be positively opened on the discharge side of the machine is simple, inexpensive and very eieient and positive in action, and comprises one or two wheels which are so located with reference to the pins or projections 60 on the covers that said pins or projections engage with said wheel or wheels and in order to pass by the same, are forced outwardly and away from the bottle receptacles.

I prefer to employ two rotatable wheels 90 and 91, disposed at the sides of the tank lOt and outside ot the line of travel of the bottle receptacles but within the lines of travel of the projections or pins (30. As a matter of convenience in constructing` the machine, l support these wheels upon the guides Gl, the center of each wheel being located inside the path traversed by the pins (30, with the result (as clearly shown in Fig. 2) that when said pins contact with the periphery of a wheel, they are forced outwardly and away from the bottle receptacles in order to pass by said wheel.
