This invention relates to improvements in flue connections for stoves, the invention, as will appear from the following description and accompanying drawings,- being more specifically directed to and designed as a flue connection for gas ranges having a top cover. for cooking burners.

lhe public demands that kitchen furniture be made more pleasing in a pearance grow m increasingly stronger each ay, and to meet these demands stove designs, particularly gas stove-designs have materially changed in recent years. The stove or range illustrated in the accompanying drawings is an out- .growth of this pubhc demand as it will be seen that a hinged or swinging cover is rovided for the cooking burners to hide t ese burners from sight and the present invenprovided a range which is of most pleasing appearance in that all burners and utensils are hidden from view and which is one of the objects of the present invention. -v

Another advantage and object which is an outgrowth of the present invention is that cooking under this closed top with the resent flue connection insures that all coo -ng odors are carried .ofi.v H A range utilizing the present invention also has the advantage that it will not tend to heat up the kitchen as greatly as do those ranges or stoves of the'common and well known type wherein the cooking burners are open and permit the delivery of heat and odors into the room.

Another object of the invention is the provision of ailue connection so constructed as to beoperatable with and form a part of a swinging top'cover or other moving part. c

A still further improvement which is an outgrowth of thepresent invention is that gases, products of combustion and odorous vapors are carried ofi'from the range so that there is no possibility of them discoloring the walls adjacent to the range.

Other objects, novel features of construction and improved results of the invention will appear from the following description and accompanying dra a 1 In the drawings:

Fiiire 1 is a plan view of a range mayini t e present invention.

igure 2 is a rear view.

Figure 3 is an end view.

Figure 4 is a fragmentary end view similar to Figure 3,theswinging cover being shown in raised or elevated position.

Figure 5 is a fragmentary view in vertical section taken on the line 5-5 of Figure 2..

Figures is a fragmentary horizontal sectional view taken on the line 6-6 of Figure 1. Figure 7 is a diagrammatic view partly in vertical section illustrating the joining or abutting ends of the stationary and movable portions of the flue.

Reference now being had to the drawings in which the preferred embodiment of the present invention is illustrated and wherein the range to which the present invention is I applied comprises at one side the cooking and broiling oven A having the usual outlet fiue B having a collar 10 for connection with. an outlet pipe or conduit,

At its opposite end the range base 11, which base is incidentally supported above the floor by the usual legs 12 is provided with cooking burners l3 fed from a common gas manifold 1e concealed within a housing 15 having a closed front wall 16, side or end wall 17, rear wall 18 and closed at its other side through abutment with one side. of the ovens A in gas ranges the cookin burners 13 are beneath either a solid cooiing top or are beneath a cooking top composed of a grid. Ehe present invention is applicable to stoves or ranges utilizing either form of cooking top.

I The cover for the cooking top is designated'at G and in Figure3 of the drawings it will be seen that it is in its lowered position to close in the cooking burners 13 and for the purpose of appearance is of a height similar to the difference in height between the burner chamber 15 and the height of the ovens A so that when the cover is in lowered position the cover top 19 is in the same horizontal. plane and level with the oven, top 20, as clearly is illustrated in Figure 2 of the drawings. This'cover is pivotally mounted. ap-

proximatel midway its length and provided with a hen le 21 by which it can be raised and lowered.

By reference to Figure 4 the position the cover 0 assumes in its raised or elevated position will be clearly seen and from this figure it will be apparent that the rear portion of the cover telescopes the burner chamher as the side wall 22 of the cover parallels the end wall 17 of the burner chamber while the top 19 of the cover parallels the back wall 18 of the burner chamber.

The cover is provided with a rear wall 23 which is hinged at its upper edge at a plurality of points 24 to the under side of the rear edgeof the" cover top so that when the cover is in its raised position this cover back 23 parallels the rear wall 18 of the burner chamber as is clearly illustrated in Figure 4 of the drawings and. by assuming thisvpiosh tion permits the raising of the cover. ion the cover is lowered its rear wall 23 falls by gravity into the proper position to close the rear end of the chamber formed by the cover as is clearly evident in Figures 2, 3 and 5 of the drawings. I

At the rear of the range the ordinary outlet -fiue B of the ovens is provided with an extension D to which extension is connected the fiue'E forming a part of the back wall 23 of the cover. a

As the cover flue E moves with therear wall of the cover it is necessary to provide a special form of connection betweenthe fines D and E; In Fi res 2, 6 and 7the construction which ma es this possible is illustrated. Here it will'be seen that the top 25 of the yon t etapered outer end 27 of the rear wall 28 of this flue and that the bottom 29 of the flue vends atthe bottom of the taper 27 or in other wordsis considerably shorter than the to 25 of theflue. y v The flue is made in the reverse manner. That is to say, its outer wall 30 is tapered as at 31 in a reverse direction. to the taper 27 of the outerwall 28 of the flue D while its -bottom-. .32-has an outwardly extending end 33beyond the edge 34-of the rear wall 23 of p the cover., The top 35 of the flue stops short of the flue;

one anot of the edge 3401? the cover rear wall 23 or in other words is shorter ,than tl1e bottom 33 By reason of the constructiondescribed and illustrated the two fines D and E can ,be swunfiinto and out of engagement with or in a telescoping manner. It will flueiortion D, has an extending end 26 hemanner be seen that the extending portion 26 of the flue D will act as a stop for the top 3.5 of the flue E as it will overlap upon the flue E as clearly illustrated in Figure 6 of the drawing ,while. the extending portion 33 of the bottom-of the flue E will overlap-and abut the outer face of the bottom 29 of thefiue D as is also apparent in Figure 6 of the drawing. The rear wall 30 of the flfu'e E overlaps the rear wall 28ofthe flue D. Thus it will be seen that through these-overlapping enga ements a continuous flue is ovided when t e cover is in its lowered or cosed position,

From the foregoing it" will be seen-that there is provided a range having all of the attributes and advantages hereinbefore pointed out and at the same time having as a part of its structure a flue arrangement which is necessarily periodicall broken and yet at the same time is of suc a structure to permit this. tem orary breaking of the fine in what would he termed an automatic manner as there is no necessity for the loosen ing or tightening of bolts, screws orany fastening means. p v

The depth or height of the cover is suficient to form a covered cooking compartment in that it provides sufficient room, when the cover is in closed osition, to accommodate cooking vesselsv oi difierent characters so that cooking can be carried on with the cover without departing from the spirited the invention, as for instance on stoves or ranges using other forms of fuel as a heating me dium. e
