9 Claims. (Cl. 126-214) This invention relates to improvements in stove top assembly.

This application is a division of our co-pending application for Letters Patent, Serial No. 586,702, filed April 5, 1945, issued October 18, 1949, No. 2,485,359.

T-he principal objects of this invention are:

First, to provide a top for a c'ook stove of a one-piece seamless character which will be more attractive and easier to keep clean than tops known heretofore.

Second, to provide a top assembly for a stove which may be attached by an unskilled workman, with two concealed bolts.

Third, to provide a. top for a cook stove which permits easy accessto the burner adjustment and connections positioned below the top.

Objects -relating to the economies and details of the construction of the top will be apparent from a consideration of the following description. The drawings, of which there are two sheets illustrate a preferred form and one modified form of the invention.

Fig. 1 represents a plan view partially broken away of the top as installed on a cook stove.

Fig. 2 represents an end elevational view of the top in partially assembled position on the stove.

Fig. 3 represents a front elevational view of the front frame member of the stove which supports the top member.

Fig. 4 represents an enlarged perspective view of the stove frame structure at the rear corner thereof arranged to cooperate with the top.

Fig. 5 represents a vertical cross sectional vie-w taken along the line 5-5 of Fig. 1.

Fig. 6 represents a vertical cross sectional view taken along the line 6-6 in Fig. 1.

Fig. 7 represents an end elevational view of a modified form of stove top.

Fig. 8 represents a plan View of the top illustrated in Fig. 7.

In the drawings the reference character I indicates a stove top consisting of a top panel 2, a depending forward apron 3, and a raised rear fence I. The top panel, front apron, and rear fence are formed with a continuous surface as one stamping and are provided with merging end flanges 5 and a top flange 6 along the top of the fence 4. A vent outlet 1 is formed in the top flange 6. The top panel 2 defines a series of burner apertures l8 which are disposed over the burner elements at 9 and arranged to receive burner bowls I0 supported upon the raised bosses II. The forward burner openings 8 are formed with extensions I2 on their forward sides so that Divided and this application June 4,

when the burner bowls are removed, the mixing valves I3 for the burners are readily accessible. The rear burner openings are formed with extensions I4 on the -rear sides thereof so that access may be had therethrough to the connection I5 between the fuel manifold I6 and fuel supply pipe.

The end flanges 5 on the top panel are provided with inwardly turned flanges I8 (see Fig. 5) and the front apron portion 3 is provided with a backwardly turned flange I9 (see Fig. 6) so that the top may be attached to the body of the stove in a manner to be described presently.

The stove body to which the top is arranged to be attached includes the front frame member 20, rear panel 2 I, and top cross members 22. The front frame member 20 is formed as a unitary stamping with end vertical members 23, a center vertical member 24 and a horizontal top portion 25 defining a large horizontal slot 2'6 and two smaller slots 21 therebelow. The large Slot 26 is provided with forwardly extending flanges 28 at the top and bottom thereof and the top of the horizontal portion is formed with three upstanding ears 29 and two sloping portions 30 defining bolt holes 3|. The top cross members 22 are flanged inwardly as at 32 along the top edge thereof and are welded at their forward ends to the end uprights 23 of the front frame member and at the rear to the forwardly extending flange 33 of the rear panel 2|. It will benoted that the cross members 2l extend backwardly beyond the rear panel. Thev rear panel is formed with upstanding ends 34 at each end thereof arranged to be welded to the inturned flange 32 on the top cross members.

A burner chamber bottom panel 35 is provided with an upturned flange 38 on the back edge which is welded to the back panel 2| and a downwardly offset edge 31 along its forward edge which is welded to the back of the front frame member.

Burner support bars 38 have their forward ends supported on the top of the lower flange 28 of the front frame member and their rear ends supported on the burner chamber bottom panel near the rear panel 2I. Burners 39 are supported on the burner support members underneath the openings 8 in the top panel and are provided with mixing valves I3 Positioned underneath the forward extensions I2 in the forward burner openings. The fuel manifold I6 is bent from the back of the burner chamber and extends along the front of the stove and within the horizontal slot 26 in the front frame chamber. Bolts 40 secure the manifold to the sloping portions 30 of the front frame member. Fuel valves 4I are connected to the manifold for delivering fuel to the mixing chambers 40 and control shafts 42 project forward therefrom for connection with control knobs 43 on the forward apron section of the top member.

Secured to the inturned flange 32 of the end cross members is a spring clip 44 which is provided with a central portion 45 which extends across the forwardly turned flange 34 on the rear panel. Each end of the center portion 45 defines an aperture 46 and is turned downwardly into a lower flange 41. The lower flanges 41 are welded to the top flange on the end cross member by means of welding electrodes which are passed through apertures in the center portion 45. The end flanges 41 are further bent upwardly into the end clips 48 which are spaced upwardly at a higher level than the center portion 45 of the clip.

The center portion 45 of the clip is spaced above the top of the cross member 22 and arranged to receive the inturned flange 49 of an outer decorative end panel 50 while the end portions 48 of the'clip are spaced so as to receive the inturned flange I8 of the top member between themselves and the center portion 45. The clips 44 thus slidably secure the top member to the body of the stove. The inturned flange I9 along the bottom of the apron portion 3 is arranged to'iit underneath the lower flange 28 of the horizontal opening in the front frame member. Two bolts are provided for securing the flange I9 to the flange 28, thus eiectively securing the top member to the stove while at the same time leaving the top member readily demountable for separate packing and shipment or repair of the stove. Doors 52 are provided for the openings in the front of the stove which effectively conceal the bolts 5| when the doors are in their normally closed position.

In the modified form of the invention illustrated in Figs. 7 and 8 the end flange 54 of the top portion is extended to the same width as the depending apron portion 55 at the front of the top member. In employing this form of the invention the cross members 22 and the clips 44 on the stove frame will be correspondingly lowered.

The top portion 56 is altered in that the burner apertures 51 are positioned in pairs at each end of the stove rather than in a group of 4 as in the preferred form of the invention.

The invention has been illustrated and described in a highly practical commercial embodiment thereof. No other adaptation has been shown as it is believed that this disclosure will enable those skilled in the art to adapt the invention as may be desired.
