CAsING ron. IIIILTIILA THERMOMETERS AND-THE LIKE.

To all whom it may'ooacem:

Be it known that I, EDWARD P." COLE, .a citizen 'of the United States, residing at Chicago, in the` county of Cook and, Stateof Illinois, have invented certain new and useful Improvements in Casings for Metal Thermometers and thelikeVof which the following is a specification. Y r Y My invention. rel. testo 'acasing which in the particular embodiment illustrated in the accompanying drawings and hereinafter described is designed to'inclose` a bi-metal thermometer used for measuring temperatures of several hundred degrees, such as are largely used for indicating the heat of ovens for baking food in stoves and ranges for domestic or commercial purposes. The particular construction ofthe thermometer has nothing to do with my present invention, which relates entirelyvto a casing adapted to receive and support such a thermometer Vproperly in a wall of the oven structure, 'or

serve any similar purpose; The object of my invention is to provide a simple,`attrac tive and desirable casing for such a device whichshall be cheapl to` manufacture, easy to apply Ato the voven upon which the therf mometer is tombe used, andpwhichvshall be well adapted to serve the purposes for which it was designed. AWith this objectin view my invention resides inthe construction,

structural arrangement and organization of the members which make, upvmy novel and improved casing, as hereinafter explained and described, the essential elements of my invention being more particularly pointed out in the appended claims.

Figure 1 of the drawing forming a part of this specication is a face view of a casing embodying my invention; Fig. 2 is a perspective of the lower or box member of the casing; Fig. 3 is a perspective of the dial member; Fig. 4 is a perspective of the cover frame, showing the underside thereof; and Fig. 5 is a central transverse section of the casing.

The same reference characters indicate the same parts in all the gures of the drawing. The bottom or box member of my novel casing, see Fig. 2, may be conveniently formed of a sheetmetal blank cut and bent to form a rectangular bottom section 1 and connected flanges or members forming sides 2 and ends 3, each of the latter having an outwardly extending ear 4 in the same plane as the top of the sides 2. In the present insimilar manner.

stances, as shown,thebirmeta1istrip 5 ofthe y thermometer device is secured to a Vblock 6 fixed to the bottom of the casing, and is operatively connected with the ,indicating hand f7 pivotally mounted upon a post8 also secured to the bottom of the casing. A slot 9 in the bottom 4 is Vprovided adjacent the strip `5 to expose the latter to the heat of the oven.

The dial memberl 10, see F ig. 3, isialso formed of a rectangular sheet metal blank which near each end is lformed with a fold or. crimpll adapted to fit over and seat upon the 'upper edges of the ends-3 of the box member. The intermediate portion of the dial plate member is formed with a slot 12 Vextending from one side edge toward the center, yto receivev the post 8, and may be enameled or Vfinished in any suitable manner and provided ywith a scale to coperate with .the indicating hand. Outside the line of the lcrimps 11 the flat end portions 13 lie on top ofthe ears 4, and the parts 13 and 4 are formed with registering orifices 14 to admit bolts by means of which the casing is secured to the oven. These end portions 13 may be omitted, however, if desired. It will be understood the oven Wallis formed with an opening just large enough to receive the box `member as far as the ears 4, and that the casing is secured to the ovenwall by bolts uextending' therethrough.

p The cover frame 15, which may be a metal casting, is formed with va central display opening 16 exposing the .dial scale and hand andadj acent its margin bears upon and surrounds the outer edge of the dial member 10.

The proportions and arrangement of the parts is such that between the top of the folds 11 and the inner face of the cover frame there will be a space of proper size for the reception of a vcover glass 17 for protecting the indicator hand.

The inner side of the cover frame 15 is formed with a pair of opposite bosses tapped for the reception of the threadedends of headed screw bolts 18 which extend from the inside of theoven wall through the orificesv in the parts 13 and 4 before mentioned, and. which serveto'secure the casing in place in the oven wall.

' It is Vobvious that while my casing is` well adapted for the particular use above described, it may be adapted to incase any desired article and be secured in an opening in any kind of wall or other structure in a member formed with a bottom an I claim formed with a bottom and side and end members, one pairof opposite members being longer than the other, a dial member formedwith parallel projecting folds arranged to fit over said longer members, and a cover frame formed with a display opening and having marginal flanges arranged to' receive said 'dial member.

2.A casing comprising a box member formed with Ya bottom and side and/end members, one pair of opposite members being longer than the other, and being formed with earsprojecting parallel with said bottom and lying in the plane of the freev edges of the other sides, a dialv member formed with parallel projecting folds arranged to fit over said longer members and' also arranged tov vseat upon said ears of the longer members andthe edges of' the other members, and a cover frame formed with a display opening and having marginal flanges arranged to'receive said dial member.

casing comprisinga boxV member formed with a bottom and opposite members forming ends, said members being formed with outwardly extending ears parallel with said bottom, a dial member arvran ed to seat against said outwardly exten ing'ears of the ends of the box member,

said dial member and outwardly extending ears being formedwith registering orifices, and a cover frame formed with a display opening and'having marginal flanges arranged to receive the edges of said dial member. Y

4. A casing comprising Va rectan ular box opposite marginal members forming ends, a rectangular dial member formed with parallel projecting folds arranged to fit over said end members and with an indicator post slit intermediate said end members and parallel therewith, and a cover frame formed witha reetangulardisplay opening exposing the inner endof' said Vslit, and provided with marginal flanges arranged to receive the edges of saidv dial member.

5. A casing `comprising a sheet metal bottom formed with atleast two opposite marginal members, a sheet metal dial member formed with projecting folds arranged to fit over said :marginal members, and a cover frame formedwith a display opening and arranged tov engage the margin of said dial member. Y

6. A casing comprising a sheet metal bottom formed with at least two opposite marginal members, a sheet ,metal dial member formed with projecting'folds arranged to fit over saidmarginal members, a cover frame formed with a display opening 'bearing upon said dial member adjacent' its edges, and al glass cover plate arranged between said vcover Vframe and the foldsof said dial member.

7. A casing comprising a rectangular Vsheet metal box memberV formed with a bottom and opposite members forming ends, a

rectangular dial'member formed with parallel projecting,A folds arranged to fit over Ysaid ends, and a cover'frame formed with a display opening and having flanges arranged to receive the vmargin of said dial member.
