RANGE.

Original application filed April 2, 1921,, Serial. No. 458,105. Divided and this application flled August 1,

' 1922. Serial- No. 578,982.

This application is a divisional of my pending application Serial No. 458,105, filed a range.

The present invention has as its object to provide a range having various features of novelty and advantage.

In accordance with the present invention, the framework of the range, for the most part, is formed of irons angular in trans verse section; the cover plates and panels are formed of sheet metal pressed or bent ,into the desired shape, and the parts are so 1 arranged and assembled that practically all bolts, rivets orother means for securing-the parts together are hidden from View; consequently the range presents a very. pleasing 2b ,and neat appearance and, furthermore, there "being noexposed bolt heads, or the like,

about which grease or other foreign matter can accumulate, it is very easy to kee the range in a clean and sanitary condltion.

Since the range is almost entirely made up of light metal parts, which may be cheaply and easily assembled, a very economic structure is presented, while at the same time the parts are so arranged and secured together that the range has the necessary rigidity and strength.

In the accompanyino drawings;

Fig. 2 is a perspective view of the skeleton or framework'of the range;

. Fig. 3 is a vertical sectional view taken through the back of the range on substantially line 3-3 of Fig. 4, the shelf and heating unit thereon being in central section and the oven being omitted;

Fig. dis a horizontal sectional View taken on' substantially line H of. Fig. 3 through the backof the rangebeneath the oven; and

Fig. 5 is a sectional view on line 55 of April 2nd, 1921, covering improvements in Fig. 3 and shows the manner in which one of the end panels is assembled on the frame.

From Fig. 1 it will be seen that in general arrangement the range has a body port1on a supportedon legs I) and provided with a to plate a carrying electrical hot plates (Z. tising from the rear edge of the body portion is a back e and extending from this back and spaced above the top plate is an oven f. Alongside of the oven is a shelf 9 which may also be provided with a hot plate 2'.

The construction of the framework of the range will be most clearly understood by referring to Fig. 2. It will be seen that the frame for the body portion of the range comprises two similar rectangular members 10 and 11, each formed of angle iron, and

corner brackets securing these members in spaced relation, the rear corner brackets'being designated by the numeral 12 and the front ones by numeral 13. .In' the present instance, the front sill and the side sills of each of the members 10, 11 are formed of one angle iron, while the rear sill is made separately. The angle between the horizontal and vertical webs of the angle irons forming the top framemember 10 faces inwardly and upwardly, while the angle between the webs of the bottom frame member 11 faces inwardly and downwardly. The horizontal webs of the members 10 and 11, respectively, are secured by spot welding,

rivets or otherwise to the upper and lower ends of the brackets 12 and 13. Each of the front corner'brackets 13 may be of an ularv shape in cross section and is provided with flanges 15 at its upper and lower ends to which the horizontal webs of the members 10 and 11 are secured. Extending from the front edges of the-brackets 13 are wings 1,6

which receive the covers for the switchesvis preferably formed of sheet metal.

are secured to the outside corners of the rear corner brackets 12. The framework which constitutes the corner irons for the oven comprises two members 23 of similar construction and each being formed of an angle iron bent to the shape shown. These members are suitably secured to the mem-. ber 20. It will be noted that the back frame extends'upwardly, then laterally, then downwardly, then laterally, and then downwardly, thus providing at the side of the oven a vertical intermediate portion 20 to which one of the members 23, constituting a corner iron of the oven, is secured. This provides for simplicity in construction and economy in manufacture. The numeral 2-1: designates bracket arms secured to the member 20 and supporting the shelf 9.

From Fig. 3, it will be seen that the legs I) are secured by means of screws 21 to anchor members 22 positioned in the corners of the frame member 11 and secured thereto by bolts'25. It will be noted that the legs may be attached to and detached from the range with great facility as ready access may be had to the screws from beneath the body portion of the range. The flanges of the frame member 11 conceal the anchor members 22.

The manner in which the end panels 26 are assembled on the body portion of the frame is shown clearly in Figs. 2 and 5. It W111 seen that the upper and lower edges of the panel 26 are turned inwardly providing flanges 27 and the upper and lower ends of the braces 17 and the brackets 12 and 13 are notched as at 28 to receive these flanges. Thus each panel may be very easily assembled by merely bringing the flanges 27 into registry with the notches 28 and then pushing the panel inwardly, no other means than friction being provided for securing the. panel in place.

From Figs. 1, 2 and 3, it will be seen that the oven is supported on brackets 30 and 31 which rise respectively from the cross strut 18 and the right hand side sill of the member 10. These brackets in one manner of speaking constitute portions of the framework. At the left hand end of the range 15 a bracket 32 preferably formed of sheet metal and which aids in supporting the shelf 9. The shelf 9, together with a panel 33 rising from the back edge thereof, The edges of the shelf are bent to form a depending skirt 34, and the edges of the panel 33 are bent to form a flange 35 which fits snugly within the portion of the frame member 20 at the left side of the oven. Beneath the shelf 9 and between the brackets 32- and 30is a sheet metal panel 36 the edges of which are also turned inwardly to provide flanges 36*. One side flange of this panel" abuts snugly against the'bracket 32 and1 the other engages in a rearwardly facing angle formed by a laterally extending flange 37 on the bracket 30. Beneath the oven and positioned between the brackets 30, 31, is a panel 38 similar to the panel 36. These panels may be inserted from the back of the range and are held in position by studs or pins 39 in the rcarwardly extending webs of the brackets 30, 31, and taking into notches 40 in the flanges of the panels, as most clearly shown in Figs. 3 and 4. The top plate 0, preferably formed of sheet metal, is recessed or slotted at its rear edge to accommodate the brackets 30, 31 and this rear edge is upturned to form a lip 12, as shown in Figs. 1 and 3. It will be seen that the lower ends of the panels 36 and extend below the upper edge of the lip l2. If desired, the panels 33, 36 and 38 may be white enamclled.

Positioned at the front of the body portion a between the corner brackets 13, 13, are. the switches 4% with their fuses as illustrated in my aforesaid application. It is preferable that the switches and the fuses be enclosed to effect a neat appc'hrance while at' the same time access thereto may be readily had. To this end, there are provided removable cov'er plates 49 and 50 for the switches and fuses, respectively. The ends of the covers 4-9 and 50 seat'on the wings 16. I

To prevent grease and the like, which may splash onto the top plate, from running down between the hot plates (Z and the edges of the openings in which they are positioned onthe top plate 0, the edge of each of these openings, as most clearly shown in Fig. 3, is bent upwardly to form an upstanding lip 53,-and the hot plates have laterally extending, downwardly curved flanges 54 covering these lips.

The rear of the back 6 and the oven may be covered over by a sheet or plate of metal 56. The angle iron members of the framework are suitably apertured, as at 57, to receive theinsulators for the conducting wires (not shown) leading to the hot plates. It will be noted that all of the conducting wires are concealed from view, those for the hot late 9 and the oven heating unit being led t rough the space provided between the rear plate 56 and the panels carried by the back frame.

It is, of course, obvious that the invention 1. In a device of the characterdescribed,
