BREWERS VAT.

SPECIFICATION forming part of Letters Patent N 0. 694,267, dated February 25, 1902. Application filed August 29, 1901. Serial No. 73,726. (No model.)

To all whom, it may concern.-

Be it known that I, WILHELM GRIESSER, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Brewers Vats, of which the following is a specification.

My invention relates to brewers vats and other like wooden storage vessels, the same residing in the construction and means of securing in place the metallic fittings surrounding the manhole and in the means for mounting the door. In this class of inventions it is common to employ around the manhole a metallic frame made up of an inner and an outer ring secured to each other and to the staves of which the vessel is made by bolts extending through said staves and through said rings. One important objection to this old means of construction is that the openings through which the bolts pass provide passages through which the contents of the vat or vessel leak. It is also common to mount the manhole-door upon pivots or hinges, so that it may be swung inwardly for opening the manhole and outwardly for closing the same. The hinges or pivots on which the door is mounted, however, in the old constructions form rough or uneven places on the interior of the tank and provide lodgment for dirt and filth, which tends to'breeddisease bacteria and to render the vats difficult to clean and really unfit for further use.

The object of my invention is to so construct and secure in place the rings constituting the metallic frame surrounding the manhole that the bolts by means of which said rings are secured in place are located outside the line of connection between the door and the vat, so that access to said bolts and to the openings through which they pass-is cut off from the liquid contained in the vat.

A further object of the invention is to construct and arrange the hinge 'on which the door is mounted for pivotal movement at a point removed from the interior of the vat or vessel, so that the contents of the vessel when filled are cut off from said hinge.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be set forth in the claims.

In the drawings forming a part of this specimanhole 1.

fication, Figure 1 is a face view of the manhole portion of a vat or storage vessel, showing my improvement. Fig. 2 is a sectional view of the same on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 1, and Fig. 4 is a detail view of the hinge.

The manhole 1 in the vat or vessel 2 has been shown as elliptical in shape; butit is obvious that it may be circular, rectangular, or other suitable shape. Surrounding the manhole 1 and secured to the outer surface of the staves of which the vat or vessel 2 is made is a metallic ring 3, corresponding in shape with the manhole 1 and having itsinner edges fiush with the Walls of said manhole. On the inside of the vat or vessel 2, opposite the ring 3, is a metallic ring 4, said ring 4 being provided with a rib or flange 5, which projects therefrom into the interior of the vat, as clearly shown. The flange 5 is formed around the outer edge of the ring 4, and the base portion of said ring, which lies in contact with the inner surface of the vat 2, is provided with a plurality of bolt-openings, through which the securing-bolts 6 pass. These bolts extend through corresponding openings in the staves of which the vat or vessel 2 is made and in the ring 3. The outer ends thereof are provided with nuts 7, by means of which both the rings 3 and 4 may be firmly and securely clamped to the body of the vat.

The door'8 is located within the vat 2 and is of a shape corresponding with that of the Around its outeredge are formed the flanges 9 and 10, substantially parallel to each other and forming between them a groove or channel 11, in which is adapted to fitwhen the door is in its closed position the flange 5 on the ring 4. Seated in the groove or channel 11 is a packing ring or gasket 12, against which the flange 5 bears when the door is closed, so as to produce a tight joint between these parts. The said door is provided with the bracing or strengthening ribs 13, which terminate at the center ofthe door in the lugs or projections 14. Said door is also provided in line with but outside of the lugs 14 with the lugs 15. Through the lugs 14 and 15 extends a pin or bolt 16, to which-is pivotally connected a clamping bolt 17, extending through a bridge-piece 1S and having a nut 19 upon its outer end. The opposite ends of curing the door 8 firmly in its closed position,

but for the formation of a close impervious joint between the flange 5 and the packingring 12, which prevents the leakage or escape of the liquid within the vat when the door is in its closed position.

The door 8 is mounted upon a hinge 20, so that when the nut 19 on the end of the locking-bolt 17 has been removed said door will be free to be moved inwardly within the vat for the purpose of opening the manhole to provide access to the interior of the vat. The hinge 20 is what may be termed a double hinge, being made up of the pivoted sections 21 and 22. l The section 21 is pivoted upon a pin 23, mounted in lugs or projections 24 on the ring 4, and the section 22 is provided with a yoke or fork at the end opposite its point of connection with the section 21, the

branches

25 and 26 thereof being pivoted to the bolt 16 between the lugs 1-1 and 15, as clearly shown. Now it will be observed that when the door 8 is in its closed position all parts of the hinge 20, on which it is mounted, are cut off from the interior of the vat. Contact between the contents of the vat and said hinge is therefore prevented, and any dirt or foreign matter on the hinge is prevented from contaminating said contents. It will also be observed that when the door 8 is in its closed position the bolts 6, which secure the rings 3 and 4 in place, and the openings through which said bolts pass are cut off from the interior of the vat, so that there is no danger of leakage of the contents of the vat through said openings. The latter result is obtained, as will be apparent, by forming the flange 5 around the outer instead of around the inner edge of the ring 4 and extending the securingbolts for the ring 4 through the base thereof.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is- I 1. In a storage vessel having a manhole or other opening therein, the combination with a metallic ring on the inside of said vessel and a door cooperating therewith to form a sealing-joint, of securing means for said ring located between said joint and said manhole.

2. In a storage vessel having a manhole or other opening therein, the combination with r a metallic ring on the inside of said vessel and a door cooperating therewith to form a sealing-joint, of bolts for securing said ring to said vessel, the said bolts and the openings through which they pass being located between said joint and said manhole.

3. In a storage vessel having a manhole or other opening therein, the combination of a ring secured to the inner surface of said vessel and having an inwardly-extending flange around its outer edge and aninwardly-opening door having a groove or channel therein for receiving said flange, the securing means for said ring being cut off from access to the interior of the vessel by said flange and door.

4. In a storage vessel having a manhole or other opening therein, the combination of a ring on the inside of the vessel comprising a base and an inwardlyextendin g flange around the outer edge thereof, an inwardly-opening door having a groove or channel therein for receiving said flange, and securing devices for said ring extending through openings in "said base.

5. Inastorage vessel having a manhole or other. opening therein, the combination of a ring on the inner surface of the vessel comprising a base and an inwardly-extending flange around the outer edge thereof, a door having flanges around the outer edge thereof forming a groove or channel adapted to receive the flange on said ring, a packing ring or gasket in said groove or channel, and securing-bolts for said ring extending through the base thereof.

6. In a storage vessel having a manhole or other opening therein, the combination with a metallic ring secured to the inner surface of the vessel and a door cooperatin g with said ring to form a sealing-joint, of a hinge on which said door is mounted located outside said joint when the door is in its closed position.

7. In a storage vessel having a manhole or other opening therein, the combination with a metallic ring secured to the inner surface of the vessel and a door cooperating with said ring for closing the manhole, of a double hinge on which said door is mounted, the same comprising two sections pivoted to each other and, respectively, to said ring and to said door.

8. In a storage vessel having a manhole or other opening therein, the combination of a ring secured to the inner surface of the vessel around said opening and having lugs or projections thereon, a door cooperating with said ring for closing said manhole having a plurality of lugs thereon, a pin extending through said lugs, and a double hinge on which said 'door is mounted comprising two sections pivoted to each other and, respectively, to the lugs on said ring and to said pin.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
