'STERILIZING DEVICE.

Sterilizin' Devices of which the followinor 7 D Ais a specification. i

bly invention relates to improvements in. sterilizing devices in which a suitable inclos-v ing chamberY is provided for receiving the articles to be sterilized. This chamber lis designed to receive a suitable frame-work for holding the articles. One vof the important features of my improvement is locating the frame-work and the articles directly in the chamber -which contains the sterilizing fluid. In the present invention it is designed by means of a suitable burner to convert it into steam. Suitable means is also provided for allowing the water to enter the chamber and for drawing off the same after the sterilizing is conipleted.

One of the objects of my invention is to provide a device for sterilizing glasses which are used by the public at soda water fountains in drug stores. It is desirable to provide suitable means for readily inserting and removing the glasses and at the same time to prevent the steam from escaping into the room. Suitable means is provided for indicating the temperature, pressure, and a safety valve to avoid explosions. I attain these objectsby means of the mechanism shownl in the accompanying drawings in which the figure shown is a vertical sectional view taken on a plane passing through the axis of the sterilizing device, and showing the interior construction with the basket for supporting the glasses, the cover, the inlet and draw-off pipes and the means for forcing the cover to its seat.

`eferring to the drawing in detail: 1 designates the container, or chamber having the curved bottom portion 2 for receiving the water indicated'at 3 in the bottom portion, which is to be converted into steam. This container is supported by means of the lugs 4 and 5 on the casing 6, in the lower portion of which is located the gas burner 7. 8 designates a pipe for supplying water to the chamber 2 which is connected to the boss 9 that communicateswith the interior pory tion by means of the space 10. 11 designates Specification of Letters Patent.

a shut-offvalve in the pipe 8. 12 is a drain pipe for drawing off the water and steam,

froin the chamber. 13 is a shut off valve therein. 14 designates a basket-like membei' for receiving the glasses 15 to be sterilized. This member preferably is made from thin metal as brass orcopper and is sup,` portedin the container 1 by means of the r rim or bead resting on the lugs, 1G. The

bottom of the member14 is perforated as shown at 17 to permit the steam to readily enter the space in which the glasses are located. The steam can also pass above the glasses as readily understood. s

The chamber 1 is closed at its top by means of the cover 18, which is formed with a chambered portion 19 having the packing 2O therein. This cover is raised andr lowered by means of the bolt 21, which has a threaded Yconnection 22 with the supporting piece 23,

whereby when the bolt 21 is rotated by means of the handle 24, the cover 18 may be raised or lowered as desired. The lower end of the bolt 22, it will be observed, is formed with a head 25, which is engaged bythe gland 26, which is screwed into a threaded recess in the cover. This construction permits the bolt 21 to turn freely with relation to the oever. The cover is preferably made arch-shaped, as shown, for the purpose of strength.l The part 23 is also mace archn shape as shown, and preferably concentric with the cover. This part 23 is pivotally connected to a suitable pin 27, which is supported by the container 1. The'hub part 2S of thepart 23 turns on the pin 2T; the other end of the part 23 is suitably secured to a pin 29 when the cover 18 is closed. A suitable pressure and temperature gage is shown at 30 and 31 respectively, and a safety valve or blow off at 32. ln order to permit the external air to enter when the blow-off Valve 13 is opened, to allow the water and steam to escape a suitable pipe connection 33 is shown which is controlled by the hand wheel escaping into the room when the cover 13 is opened.

One of the advantages of my invention is in making the bottom part of the container 1 concave in order that a small quantity of water may be used whereby the same can be converted into steam in a comparatively short space of time, once pass upward through the openings 17 into the receptacle 14 which receives the glasses 15. It will be seen that my improveand the steam will atl have been made andl ,do notV therefore claimV Y such devices.

-It is to be understood that the. form 'of the containeris not limited to'that shown in the drawings, as other forms suitable for the purpose may be used without departing Y from the spirit'andV scope of my'invention.
