D. Roper Corporation, Rockford, 111., a corporation of Illinois Application July 16, 1931, Serial No. 551,151 Renewed January 25, 1935 20 Claims.

This invention relates to a concealed manifold gas range.

The concealment of the manifold brought with it certain problems in the matters of construction 5 and assembling. In many cases a shield or apron covering the manifold is provided as a separate piece arranged to be fastened by screws so as to permit access to the cocks and shutters by removing the apron. That, however, makes it necessary to have exposed screws, and, besides, the material and assembling costs are excessive with such a construction. It is, moreover, rather unhandy to have to remove and replace the screws whenever it is desired to get at the cocks and shutters. It is, therefore, the principal object of my invention to provide the apron as the front of a drawer fitting in the burner compartment, the said apron being'thus retractable for access to the cooks and shutters by simply pulling out the drawer. Furthermore, this construction dispenses with the necessity for a separate burner tray, because the drawer bottom serves that purpose.

Another object is to provide circular knobs for the cooks and circular holes of slightly larger diameter in the apron for the projection of the knobs through the apron and so as to permit movement of the apron to and from operative position without removal or manipulation whatsoever of the knobs. It is another object to provide other holes or louvers in the apron whose main function is to admit primary and secondary air to the burner compartment but which are adapted to serve as hand holes in the sliding of the drawer, it being, therefore, unnecessary to provide a separate handle or handles for that purpose.

The invention is illustrated in the accompanying drawing, in which- Figure 1 is a front view of a portion of a gas range embodying my invention, and

Fig. 2 is a section in the plane of the line 2-2 of Figure 1 looking in the direction indicated.

The same reference numerals are applied to corresponding parts in the two views.

7 A cabinet type gas range is illustrated having the usual double oven section'5 alongside the cooking top 6. l is one of the front burners and 8 one of the rear burners of the cooking top, the burner I being of a special construction suited for use with a concealed manifold 9, the distance between the manifold and the front burners being cut down in a concealed manifold range to such an extent that the ordinary front burners cannot be used, although no special construction is required for the rear burners. The construction of the burner I is covered in a copending application of Peter I. Hollman, Serial No. 443,646, filed April 12, 1930, now Patent No. 1,916,572, dated July 4, 1933. Specially designed cocks l are provided for delivering gas from the manifold 9 to the burners They project downwardly from the manifold and have nipples ll screwed onto the discharge ends thereof. for delivering the. gas into the burners along with primary air supplied through the usual shutters l2. The stems l3 of the cooks project forwardly and in accordance with my invention 10 are equipped with special circular knobs M. The usual stamped sheet metal shield I5 is provided interposed between the front burners and the manifold to prevent heating of the cocks when these burners are in use, so that'the lubricant provided for the easy operation of the cooks will not be dried out so readily.

In accordance with my invention the front of the burner compartment I6 is arranged to be closed by an apron I1, which forms the front of a drawer slidably received in the burner compartment, the bottom i8of the drawer being thus arranged to serve as the burner tray for protection of the contents of the burner bo'x compartment I9, in which a so-called utility drawer is sometimes provided, although in the present case a hinged door 20 arranged to be opened'like an oven door is illustrated. The drawer bottom l8 slides on guides 2| provided at opposite sides of the burner compartment 16 and, since the bottom I8 is intended to serve no other purpose than that of a burner tray, no side or back walls are provided. The apron I'I forming the front wall of the drawer is suitably stamped from sheet metal to the cross-sec- 3 tion illustrated in Fig. 2 and has a transverse lower flange 22 fastened suitably by bolts 23 to the front end of the tray 18. A sheet metal brace 24 is provided at the middle of the apron ll formed to fit under the upper edge of the apron to permit spot-welding thereof to the transverse upper flange 25. The brace 24 is suitably secured to the tray l8, as by means of a bolt 26 to make the apron H as rigid as possible. Now, a'plurality of circular holes 21 is provided in the apron II through which the knobs M are arranged to project, the holes being slightly larger in diameter than the knobs so as to insure easy passage of the knobs through said holes in the movement of the apron into and out of operative 0 position. Other holes, preferably, but not necessarily, in the form of louvers, are provided in the apron H, as indicated at 28, in proper relation to the shutters l2 of the burners so that a good supply of primary air is always assured. A cer- 5 tain amount of the air entering through the holes 28 also finds its way into the burner compartment Hi to serve as secondary air to support combustion at the burners. While the main function of these holes 28 is to admit air to the burner compartment it will be seen that they also serve as hand holes in the pulling out of the drawer when it is desired to have access to the cocks and shutters. The drawer can also be pulled out by simply taking hold thereof at the lower edge of the apron, there being no cross member below the drawer to interfere with doing that. The drawer is formed at its front end in such a way that a ledge is provided suitable for grasping the drawer for such operation, as is thought to be self evident in Fig. 2.

It is believed the foregoing description conveys a good understanding of the various objects and advantages of my invention. The appended claims have been drawn so as to cover all legitimate modifications and adaptations.
