/ Ihis invention relates to an'extensible fume guard for cookingranges and has for lts object the provision of an extensible canopy adapted tobe extended over a cooking range to direct the fumes arising therefrom to an aperture in a flue.

'Another object of my invention isthe pro vision of an extensible canopy operatively connected with a flue door adapted to effect opening of the latter when range.

1 Another object from over a range when desired and to, be

' rotated downwardly at an inclination to horizontal surface of the range. j

Other objects will appear hereinafter the novel features and combinations being more clearly set forth in the appended claims.

mounted on theflue pipes 10-and comprises a 1 7 substantially horizontal rectangulartopplate having a downwardly and inwardly disposed front edge portion 18, substantially vertical isides 19 and a lower fiange 20. The rear edge portion of the top plate of the'canopy section 14 is provided with a substantially semi-circular aperture. for accommodating a portion of the flue pipe 10:as shown in Fig.1. A canopy or guard section 21 of smaller dimensions than the section let'is slidably mountedbelow t'hetopwplate ofthe canopy section 14 and comprises a rear T edge portion '22 whichis disposed upwardly and forwardly as shown inFig. 2and is adapted to interlock with the front edge portion. 18 ofthe section 14 for limiting the extensibility of the section 21 relative to the section 14. 1 It should'also'be understood that the interlocked edge portions of the section 14 and 21 lso provide a substan- I 'tially leak proof-joint therebetween for pre-f venting the escapem'ent of fumes jwhen the j device is extended as illustratedin Fig. 2.

The canopy section '21 comprises side ele- I ments 28 having flanges 2thereon which are flanges 20 of'the side elements 19,of the rear stationarysection 14. 1 .The forward edge portionof the canopy section 21 isprovided with a downwardly andrearwardly disposed edge 1 tion .26of a third canopy section 27which is of smaller dimensions than the canopy sec-H front edge portion 28 -of the canopy section 27 is similarly provided'with a downwardly and rearwardly disposed edge 'portion29 which is adapted to cooperate with the upwardly and forwardly disposed edge portion30 of a f fourth and forwardmost canopy section 31 whichis of smaller'dimensi'on' than the section j 27 and which is slidably mounted therein. It

should be understood that the above described construction is such as may beextended to the thecompactarrangement illustrated in Fig. I

products of combustion arising fro i The rear canopy section may be employed as a shelf for storing receptacles at all times either when the guard is in extended or com pact position. It should also be understood that the sides of the canopy serve to prevent the fumes from escaping from therebelow and in directing the same in to the flue pipe 10 as hereinafter more clearly set forth. A

front flange 32 is provided on the front section 31 for preventing the escapementof fumes around the front edge of the guard.

An aperture or port 33 is provided in the 1 3i 3e 10 below the guard and is ada ted to he covered or closed by a door pivotally attached at 35 to the side of the flue pipe 10. The door 8&- is provided-at its lower extremity with a loop'meinb r which the rear end of the link 3? is iouriialed. The forward end of the link 3'? is journaled in a loop member 38 soldered to the rear portion oi? the can opy section 27 as illustrated in Fig. 2, It

should be understood that as the guard sections are moved to extended position, the link 37 is pulled forwardly and raises the door 34-.

In the modified form of my invention illustrated in Figs. 4. and 5, the rear canopy section 141-. is provided at its front edge portion with a down-curved substantially arcuate extension 89 and a rod lO disposed the section 14. The forward end of the canopy section 21 is provided with an upwardly disposed curved extension 41 which is adaptcdto be journaled on the rod when the guard is extended: fin irregular slot 4-2 of arcuate shape, isprovided the side portion 19 of the rear section l iand is adapted to receive a projection 43 mounted on the end of a spring 44-. attached tothe side of the section 23 as shown in dotted lines in l l; The projection 48 is adapted to register with the slot &2 when the guard is in extent ed position'and is adapted to be pressed inwardly against the action of the spring 4d and reengaged in another position of id slot when it is desired to alter the inclination oi the forward portion of the guard relative to the rear sect-ion l thereoh lt should be understood that the guard member may be pro vided' withas many sections as illustrated pipe 10 before longitudh j nally across the front portion oi"; the section 14 secured at its extremities in the sides-l9 oi in Figs. 1, 2 and 3 and with more, if desired;

the above described arrangement being such as will permit the inclination of the guard mounted on the side of said fluepipe adapted to close the aperture therein, and alink'ops cratively connected at one'end to said door and at the other end to one of said-extensible canopysections adapted to raisesaid door when said extensible sections are moved forwardly for uncovering the aperture in said flue pipe and to lower said door whensaid extensible canopy sections are moved rear- 'wardly for closing said aperture i V 2. 11m combination with a flue pipe 'hav ing an aperture therein, ofadoor pivotally mounted on said iiue pipeadapted to cover said aperture, a stationary canopy section mounted on saidflue pipe, a rod disposed across the toirrard end thereof, telescoping canopy sections slidably mounted on said stationary section, a curvedextens on on the edge of one of said telescoping sectionsada )tCCl to be journaled on said rod when said telescoping sections are in extended position for permitting the latter to be disposed at an inclination to said stationary section,
