STEBILIZER.

UNITED STATES PATENT OFFICE.
'JOSEPH 0. HALVERSON, OF PORTLAND, OREGON, ASSIGNOR T0 THE HALVERSON COMPANY, OF PORTLAND, OREGON.
STERILIZEB.
Specication of Letters Patent.
Patented Nov. 10, 1914.
To all whom it may concern Be it known that I, JOSEPH O. HALVER- soN, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Sterilizers, ofv which the following is a specification.
This invention relates to im rovements in sterilizers, and has for its object to pro` vide means for subjecting articles to a bath under an application of heat.
A further object is to provide a device for conveniently handling such articles in water and for' subjecting them to heat.
A still further object is to provide means for electrically heating the water in such' a device and to equip the circuit with a fusible plug which will automatically break the circuit when the temperature exceeds the normal Ilimit.
These and other objects are accomplished by means of the structure shown in the accompanying drawing, in which- Figure 1 is a plan view of the bottom of the receptacle partly in section. Fig. 2 is a longitudinal vertical sectional view taken on the line B-B of Fig. 1. Fig. 3
'is a transverse vertical section taken on the line A--A of Fig. 1. Fig. 4 is an elevation of a connecting plug partly in section, showing the fusible element.
Describing the drawing in detail, 1 designates the body of the sterilizer'having the usual supporting legs and which is provided with the usual metallic lining having the bottom portion 2, which is laid upon a bed 8 of non-conducting material, an insulation 4, such as mica, being placed between. Beneath and inclosing the bed 8 is a casing 6 secured by means of screws 3. The space therein, below said bed, is occupied by the insulating strips 7 which are held in spaced relation therein by means of the insulating supports 5, the pur ose of which being to prevent radiation rom the heating element above.
9 is a connecting plug made preferably of porcelain, over which is placed a coil spring 43 bearing against the contact ring 27. Within the hollow upper end of the plug is inserted a metallic tubular element 28, mto which is connected, by means of the usual screw threads, the screw plug 25, which is connected by means of a fusible element 26 with an oppositely disposed screw 25B. A non-conducting plate such as the washer 9a of mica is secured over the upper end of the plug to prevent possible contact between the ring 27 and the metallic elements within.
Centrally in the casing 6 is formed an aperture or socket 41 to receive the plug 9, and in the non-conducting bed is fixed la socket 24 into which engages the screw plug 258, the socket 24 ybeing held in an aperture 1n the metal bottom 2 by any usual mechanical means; and it may be further secured by solder or otherwise.
In the upper face of the -bed 8 is formed a plurality of longitudinal channels 21, each being adapted to receive a heating coil 22. In the lower face of the bed 8 in position corresponding approximately to exterior of the socket 41 are fixed contact points 23, 23a and 23D.
From the point 23, a wire 29 leads to and connects with a set of heating coils 22 which connects with wire 35 leading to contact pin l0, which may be connected with the supply circuit. From the point 23 a wire 31 leads to and connects with contact pin 10a, which also may be connected in the supply circuit; and from point 23b the wire 30 divides at 27, one branch connecting with the set 22b of heating coils and the other branch connects with the set 22c of heating coils. The wire 36 leads from both vof these sets to the contact pin 1()b which may be connected when desired in the supply circuit, by means of connector 34.
By turning the plug 9 to screw the fusible plug 25u into the cap or socket 24, the ring 27 will bear upon the contact points 23, 23a and 23b thus establishing a circuit through each set of heating coils, when the connectors are in place.
Articles will be sterilized by placing them upon the tray 18, resting upon 'the Hoor 2 and covered with water. Should the water become evaporated through neglect, or otherwise, the heat will become intensilied in the floor of the sterilizer, which will melt the fusible alloy 26, breaking the circuit before the heat reaches a destructive de ree.
cover 11 is hinged at 32 to the rear side of the body or casing 1, and at an intermediate point, iu each end is secured a screw eye 12 from which a suitable cable er chain 14 leads through the scr-ew eye n@ 16 to, and it is secured in the end member 17 of the tray 18, which is loosely fitted therein.
At a suitable point intermediate each screw eye 12 is secured another screw eye `13 to each of which is attached a flexible element 15 which passes through a screw eye 19 fixed in the front upper edge of the casing 1, whence it extends to and connects with the front side vmember of the tray 18. These screw eyes are so disposed in the cover 11 and in the casing 1, that when the cover is raised by the handle 38 at each front corner, the chains 14 and 15 will be drawn taut, and the cover acting as a lever will raise the tray where the articles contained there willbe exposed in horizontal osition at the open upper edge.
aving""described my invention, what I claim, is-
1. A sterilizer, comprising a shell having its top open, electrically operated means disposed in the bottom of the shell to heat the interior thereof, a cover hinged to the top of the shell to be swung in a vertical plane to open and closed positions, a permanently substantially horizontally varranged tray disposed within the shell and vertically movable therein while maintaining its substantially horizontal position, and connecting means between the tray and cover whereby the tray is raised and lowered, while remaining substantially horizontal, upon the swinging movement of the cover.- l
2. A sterilizer, comprising a shell having its top formed open, electrically operated means disposed in the bottom of the shell to heat the interior thereof, a cover hinged to the top of the shell to `be swung in a vertical plane to open and closed positions,
a permanently substantially horizontally` nections from said cover for moving said tray vertically in a horizontal position as said cover is raised and lowered.
In testimony whereof, I affix my signature in presence of two witnesses.
