7 Claims.

This invention relates to a'chimney cap,and it is Vanobject of the invention to `provide a de-y vice'of this kind embodying means whereby itis effectively maintained in applied orworking position and which affords an effective means" toV 108 The invention also has for an object toprovideV a device of this kind having means whereby water which mayaccumulate thereon is .effectively drained olf and in a manner whereby such water will not pass down the chimney. I`A` The invention consists in the details of' construction and in the combination and arrangement of the severalrpartsof our improvedvchimney cap whereby certain important advantages are attained and the device rendered simpler, less 201- expensive Yand otherwise more convenient and advantageous for use, as will be hereinafter more l fully set forth. The novel features of our invention will here,-V

inafter be definitely claimed, f 25.2 In order that our inventionlmay be better understood, we will ,now proceed to describe -the same with reference to the accompanying drawing, whereinzy ,Y f 1 i Figure 1 is a view partly in section and partly 30,2 in elevation illustrating Va chimney cap constructed in accordance with Aan -embodiment of our invention;` Y A Figure 2 is a sectional view taken substantially on the line 2-2 of Figure l Figure 3 is a View in top plan of thecapras herein disclosed unapplied. Y

As disclosed in the accompanying drawing, C denotes the upper or topV portion of a chimney comprising in its construction the ,general arrangement of tiers I of bricks or the like together with a conventional lining 2. The improved chimney cap A as herein set forth isi4 of predetermined configuration Vin top plan and comprises a body or head plate3 havingiits margin dene'd by a depending side walln'll2 the free or outer portion 4of which extending between the upper tier I and the lining 2. The extent of such insertion of the side wall 4 is determined by contactl of 5'0 the inwardly disposed flange 5 carried by the wall 4 and positioned a desired distance inwardly of the lower or free edge of the wall 4. This flange 5, as herein disclosed, is perpendicularly related to the side wall 4 and may be welded or otherwise 55 secured in place and without departing from the spirit-of the invention may be integrally formed therewith. t H

The side -wall 4 preferably at diametrically opposed points hasbolted, as at 6, or otherwise secured-*thereto end portions of the tie or holding 5 bars 1. These bars 'I are of material length and terminate in outwardly disposed extensions 8 to engage between adjacent tiers I, as particularly illustrated in Figure 2 ofthedrawing, whereby the applied cap is effectively` anchored in posi l0 tion. I

The body or head plate 3 is provided in its central portion with an opening!! of substantially the same dimensions as the cross sectional area of the chimney ue and disposed around such openl5 ing 9 is an upstanding ribor bead ID providing damming means to prevent water accumulating on the top of the :body or head plate.V 3 flowing down through the opening 9. The opening 9 is adapted to be closed by a cover plate I I one mar- 20 ginal portion of which having a lip l2 contacting from above with the body orfhead plate 3 when the cover plate is in closed position while the opposite marginal portion of said cover plate II is provided with a lip I4 Acontacting from below 25 with said body or head plate 3 as is particularly illustrated in Figure vl. y

Midway of the margins of the cover plate II provided with the lips I 2 and I4 is a transversely disposed channel I5 having its bottom wall I6 ta- 30 pered outwardly and downwardly from the longitudinal centerof theV channel I5 to the ends thereof. The ends of the channel I5 at the lower por tions thereof are continued through the tubular trunnions I'Ij which are integrally formedl with 35 the cover plate II. -These trunnions -I'I extend outwardly and are in alignment one with the other and of alength to extend through the bearings I8` therefor carried by the plate 3 and to terminate outwardly thereof. A 40 The `centralor high point `of the :channel I5 has inV `communication therewith the supplemental draining channels I9 provided 1in the cover plate II and disposed Jvin opposite directionswith respect Vtogeach other and4 at -right 45 anelesfwith respect tothe `groove Qrfhannel" 5A It is to be particularly noted that" the channels I5 and I9 have their top faces open and that said channels are positioned entirely below the plane of the top surface of the cover plate. As is particularly illustrated in Figure 1, each of the channels I9 has its bottom wall inclined downwardly toward the channel I5 to substantially merge with the high point of such channel I5.

The channels I5 and I9 assure eective drain- 55 ing-an opening to register with the flue of a v ing of Water which may accumulate upon the closure plate II When in closed position and such Water as drained will pass out through the tubular trunnions I1 and thus avoiding suchv Water passing down the chimney flue.

The closure plate I I may be adjusted or swung about its trunnions I'I in anymanner desired but, as hereindisclosed, said plate adjacent to each of its marginal portions pro-vided With the lips I2 for I4 has secured thereto, as at 2l), an end portion of aWire 2I or kindred element which extends down through the flue and se-` cured to the extremities of a rock lever 22. `This lever 22, as herein' disclosed, is supported by thef wall of a fireplace Within the throat portion -V thereof and said lever 22 at its ends carriesv d epending plates 24. y*

Each of theseplates 24 Vis provided with anr opening 25 to permit a poker or other member to Vbe engaged With the plate 2 4 When itis desired to operate the rock lever 22 to close the closure plate II. Y Y

InV the present embodiment of our invention the flue to which the cap is applied leads from aY conventional replace. It is believed to be evident, however, that the cap With` but slight variation vas to the" operating means for the closure plateV can be employed With equal facility in conn'ection'with any type of chimney. "From the` foregoing description it is thought to be Yobvious that a chimney cap constructed in4 accordance With our invention is particularly l. A chimney cap comprising a head plate having an opening to register with the flue of a chimney, a closure'plate for theopening, means for swingably mounting the closure plate upon the cap including a tubular trunnion open at both ends toprovide a drain for Water aecumuy lating on topof the closureY plate.
