waste matter, and preventsuch bysproducts from working their wayup intjothebitof the pipe stem. The combustiblematter; such as tobacco, is intended to be, burned above fashioned .intoi a circular platejprovided with relatively numerous perforations,v aff fording a free smoke and also a, well distributed draft throughthepipe bowl. F A further object of the present invention is to provide for improved means for suitably mounting the grate intothe pipe'bowl. To this end, my appliance is preferably equipt with a pendant abutment member to fixedly: locate the grate ineans irrespective of the bowl depth; and without resort to support straps hanging from the edg'e-glof'the bowl mouth.- fMy. spacing means :may' be formed in the shape-of a. rigid stopmember protruding fromethe grid, ?wh ich;'plate is 1 held in spaced relation with respect to the bottom of the bowl. and forms a't'rap pocket below the grate.

The rim of such a f-further :be provided "with resilient bowl, gripping means that serve to holdthe grate down in position van'cl allows aisin'gle size 0f .:grate plate to be fitted to a range of different bowl bores'.'-" Embodied herein are also, suitable:

-mea-ns'designed to permit of easy removal of the grate for pipe cleaning purposes, and

other features of structure adapted to facilitate the manufacture and application ofsaid device to smoking pipes, all of which will be set forth in further detail hereinafter.

The dished grid portion 7 of mydeviceis provided with a -series 10f ,spaced .draft 1 apertures 9, adapted to impart a screen effect and establish communicationbetwecn a trap pocket 10 and a tobacco bowl space 10 lying above the grate. To facilitateremoval of the grate, the edge of the rim 5 eral ledge or spaced claws designated-asLll.

This hOIdsthegr-id'? in a fixed relation with respect to the ibottomof the bowl while the resilient pr0ngs8 pre vent the device from falling out ofplace and together make for thoroughly practicable attachment that willreadily fit into any of the ordinary styles of pipes.

The entrance of-the smoke duct 3 into the interior of the bowl is l normally-placed close .to the bottom thereof, and'theinterconnectedtrap pocket 10t--not only' maintains -a free draft through thepipe' but-also provide ample space for the accumulation of saliva tributed draft through-the bnrning tobacco and to make for a'free and-clean smoke. 1

As a result of the use of such a pipe grate, the tobacco may also be packed more closely intothe bowlth-an applieswhen a'localized draft th'roi lgh the pipe charge is obliged to head. toward a single side outlet in the usual fashion.

Better economy in the use of tobacco is alsoaattained with my device for thereasoh that my spaced grid holds the fresh charge o ffxthe'bowl'bottom which in turn prevents the fresh tobacco from becoming impre nated :with accumulated vvaste juices; ac- -cordingly theentirebody of smoking tobac- 1 co -may :wholly be consumed down to the face 'of my grid disc without experiencing any distressing e fi'ects from smoking un-- clean tcbac-co or sucking up its salivar derivatives as is likely to occur in:the-use of the. conventional -untrapped smoking :pipe. "Vi hen itisdesired 1 to completely clean out the pipe, th-e described device may *readily be removed, whereupon the entire contents of the bowl may be. ejected and shoul'd it he- 'come necessa-ry,'-the interior thereof con- =veniently scraped of cake formation.

It isfto be un'de-rstood that itis not my in-' =tent to'limitthescope ofthe present inven- 131011 130 specific structure or materials here- 7 in disclosed, since the disposition of the parts :and especially-the described typeof :stop means 6 may :readily be varied or changed :to meet conditions of practice in --accor'dance with thejudgment "or experience .of "the 'manufac'turer, all without departing from the spirit and sc'ope-of my invention 1 as heretofore described and more particular j 1y set forth in the appended claim.

I claim: v In an accessory for smoking 1 pipes hav- =ing-a how1 portion -and-a mouth piece, a grate-like devlce rcmovably mounted with- 'in the pipe bowl and 1 comprising a perforated grid means equipped with an 11 standmg rim portion conforming to the bore contour of the bowl'and with a rigid distance piece depending centrally from said grate and adapted to abut the bottom'portion' of the bowl for grid spacing purposes, and prong means for, said rim adapted to give lateral support to the device I and prevent tilting thereof about said abutment.

In testimony whereof, 'Ihave herewith set 1ny hand this9th day of "March, 1926.
