' To all whom it may concern:

Be it known that we, ALFRED H. \VniiiuiL- LER and J OSEPl-I W. Dawson, citizens of the United States, residing in the city of St-.'

Mechanisms for Closing Covers of PasteuriZer-BasketS, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Our Invent-ion relates to a mechanism for automatically closing the covers of baskets used in pasteurizers inwhich bottles of beer are subected to a pasteurizing treatment.

' The invention is in the natureof an improvement upon that class of pasteurizers of which an exam le is to be found in Letters Patent of the nitcd States No. 755,108, issued .h-Iarch Q2, 1904., and in which there is employed a bottle. carrier having baskets provided with covers hinged to the baskets and ada ted to be opened to permit access into the askets and closed to prevent escape of contents from the basket. In the use of a pasteurizer containing carrier baskets of the description referred to, it is essential that the covers of the baskets be closed before the baskets pass through the pasteurizer after bottles have been placed therein in i order that fra ments of the bottles, which are frequently broken, may not be permitted to escape from the baskets by floating in the water in the pasteurizer. It not infrequently happens that in the use of the pasteurizers the workmen engaged in filling the baskets neglect to .close the covers after the baskets have been filled and our invention has for its object the production 'of means whereby the covers are automatically moved to closed positionswith the result of avoiding any )ossibility of fragments of broken bottles becoming discharged from the baskets. f

Figure .l' is a side elevation of a portion of V a pasteurlzer including fragments of the tank, the'carrier and our door closing means. Fig.' II is a front elevation of the parts shown in Fig.'1'. Fig. III is a top or plan view of the parts shown in Fig. I. Fig. IV is a view partly in plan and partly in horizontal section of a fragment of the rock sha :t by which a cover of each carrier basket u )ported, a fragment of one of the end mom ers of the cover and the dog carried by the rock shaft and adapted to actuate the cover. Fig. V is'a detail view of the trip lever.

- In the accompanying drawings: 1 designates the tank of the pasteurizer and 2 is an upright or post surmounting said tank. This upright is preferably of I-beam shape or of any other suitable shape that will provide side flanges 3 which receive parts to be hereinafter mentioned.

-ldesignates one of the endless chains of a carrier that supports baskets 5, the baskets being'preferably provided with hanger stirrups that are mounted on cross rods of the carrier as in the construction illustrated in the patent hereinbefore mentioned. The top of the carrier basket is at least in part closed by a cover that preferably consists of end bars 6 and cross rods 7. This cover, as shown in the drawings, ,is com-posed of two sections loosely mounted upon a rock shaft '8 that extends through the end bars of the cover sections and is journaled in the end walls of the carrier basket so that it may rotate freely in said end walls when it is actuated through nieans to be hereinafter set forth. The cover end bars 6 are spaced apart from the end walls of the basket by distance sleeves 9. A sectional cover for a basket is unimportant in so far as our present invention is concerned, and therefore, when the word cover is hereinafter used, it is to be understood as referring to one section of the cover shown that has means associated with it for mechanical operation of it. 4

10'designates a dog fixed to the rock shaft 8 -adjacent to one of the cover end bars by suitable means, such as a set screw 11. This dog is provided with a laterally projecting lip 12, see Fig. IV, that occupies a position back of theadjacent coverend bar 6 and is adapted to operate against said end bar for the purpose of swingin'gthe basket cover to a closed position when the rock shaftS is rotated by'the means to be next described. 13 designates atrip lever that is fixed to ,the rock shaft 8 by suitable means, such as a set screw 14:. This trip lever is located at one of the outer ends of the rock shaft 8 and preferably exteriorly of the carrier;

basket 5. The trip lever 13 is preferably of curved shape, as seen in Fig. 1, in order that it may extend through the carrier chain "to be hereinafter mentioned, and which is of movement of said trip lever.

A- above the basket to so position its end as to cause. it to strike against a member.

supported by the upright '2; f The tripi'lever is provided" at its lower side-with a rearf wardly projecting extension .15 which .is provided at'itsi lower end with a toe or stop 16 that; is adapted to come into-contact wit one of the PIVOl'I' -members in the "carrier. chain when the trip lever is'tripped 'to close the basket cover, thereby-limiting the degree maybe securely held tothe uprighta't any desired location. w v a 20 is an arm mounted' in tlle} bracket 1"? and extending inwardly toward the path of travel of the carrier baskets 5;

a 21 is a trip. arm that issupported by the arm 20 and is adjustable transversely of said arm 20, "the trip arm being provided with a slot 22 that receivesfl a set screw 2.3 seated in the arm 20. The'trip arm 21 is preferably of L sh'ape and it extends intothe path of travel of the free end of the trip lever 13 in order that it will be engaged by said trip lever and the trip arm is adjustably mounted upon the arm 20 in order that it may be shifted laterally relative to the path of travel of the free end of the trip arm,

thereby providing for only the proper degree of engagement between said members. The supporting arm 20. is... adjustably mounted in the bracket 17 inorder that it'. may be turned to lower or elevatethetrip arm 21 su ported'thereby' to provide for further a'chustment of the trip arm relative to thepath of travel of'thetrip lever, and said supportin arm isnormally held in a 'fixed positiony suitable 'means, such asaset screw 24.' p

In the practical use ofa 'pasteurizer equipped with our door closing cover, 'the usual? manner and as each basket of .the carrier 'moves'into-proximity with the trip farm 21, the trip lever 13 carried by the basket engages" said trip arm with the re-' sult of caus ng the trip lever to be'moved.

upwardly and forwardly relative to the trip arm and impart rotation to the rock shaft 8Q The rock shaft in its rotation, carries with it the dog 10 and the lip 12 of said dog, and said 11p by engaging the adjacent A end bar loosely mounted upon the rock shaft, acts to move said cover in a forward or outward direction in order that it will fall to a closed position over the open up- I per end of the basket.

We claim: r 1. In a'pasteurizer, the combination of a pasteurizing' tank, bottle receptacles provided with covers, a carrier for moving said receptacles'into'the pasteurizing tank, and

means for automaticallyclosing'said covers before the entry of said receptacles within said tank.

carrier comprising a receptacle provided with a cover,- .a rock shaft associatedwith said receptacle and by which said cover is loosely'supported, a member carried by said rock shaft arranged to engage said cover, a tri lever carried by said rock shaft,-and an ad ustably supported trip arm arranged in the path of movement of said lever and b which the lever is-moved to rotate said-sha t and close fsaid; cover, substantially as set forth 3. The combination in a pasteurizer, of a carrler comprising a receptacle. PIOVldGd -with a cover, a rock shaft associated with said '-receptacle andbywhich said cover is looselysupported,.a'dog fixed to said rock" I I 0 I I I 2. The combl'natlon in a pasteurlz'er, of a shaft arranged toengagesaid cover, a trip lever fixed tosaid rockshaft, and atrip arm arranged in the ath ofjmoyement ofsaid lever and by wh1cht'h lever'is moved to cause it to-rotate said shaft'to close. said cover, substantially as set forth.
