STOVEPIPE-I-IOOD.

I Specification of Letters Patent. Application filed March 13, 1912. Serial nopes'asia Patented Dec.24,11912.

To all'whom it may concern: I

Be it known that I, WILLIAM J ."KENELY, a citizen of the United States, residing at Elizabeth, in the county of Union andState ofNew Jersey, have invented certain Improvements in Stovepipe-Hoods,of which p the following is a specification.

The objects ofthe invention are to provide animproved hood for gathering the jrising vapors, odors and the like and defleeting the same from a cook stove into the *stovepipe; to provide suitablemeans of es-- cape for such vapors, which shall not interfere with the draft or efficient operation of the stove; to provide means forclosing the vent, which means shall be readily operated, to secure a rigid but detachable hood; to segcure simplicity of construction and'installfment, andto obtain other advantages and ing description.

results as may be brought out in the followqReferr'ing to the accompanying drawings,

,in which like numerals of reference. indicate the same parts. throughout the several views, Figure 1 is a sideelevation of my device applied to a length of stove pipe, parts of the hood being broken away for the better disclosure ofthe invention;Fig. 2 is a I. 1 plan view of the sameyFig. S is a'vertical section on line AA of Fig. 2; Fig. 4 is a front elevation with the hood removed, and

Fig. 5 is a cross-sectional view on 1ineB-B of Fig. 4, looking in the direction indicated by the arrows. I I

In the specific embodiment ofthe invention illustrated in said drawings, 1 designates a length of stovepipe to'whi'ch the invention is applied. As the principal application of the invention is to any stovepipe leadingfrom the ordinary kitchen range to the chimney. proper,,it is evident that the I invention is not restricted to a pipe of circular cross section, such as shown in the drawings, but is applicable to the various sizes and shapes of pipe in use.

.Circumferentially of'the pipe, and extending approximately halfway around the same, is a strap of sheet-metal 2, held thereto by rivets 3 near each end,'or otherequivalent means, The major portion of the strap 2 is offset, as ate, to provide a slot 5 between the strap and the pipe. The pipe is p red as at 6, said aperture commenc ng between the pper and lower-edges of "the strap 2, preferably, and extending downward'for some distance below said strap.

The sheet-metal at eachof the vertical edgesof'this aperture is'doubled back as at u 7, see Fig. 5, and then returned forward again substantially parallel to itself in spaced relation thereto,: as at 71, forming; thereby a slideway 8 between theportions 7 and 71 mentioned. The slideways 8 thus I extend slightly under the strap 2, and are prevented from undue expansion or inadvertent distortion by engagement with the said strap.

. Slidably'mounted within the above'men tionedslideways 8, is aslide or vent regulator 9, preferably constructed of sheet metal similar to that of which the pipe is composed, and curved transversely of itself concentric therewith. A stop 10. is stamped from, and bent outwardly perpendicular to the. slide 9, preferablyfcentral of the lower edge, so that when thefslide is raised or opened, the stop 10 .engages the strap2,

thereby limiting the upward movement of the slide. The material of which the slide is "composed is bent outwardly, above the strap 2, and then bent upwardly again at 12 with reduced 'widthof metal to form a handle, the upper extremity of such handle 12 being provided with an outwardly projecting finger-piece 13 suitablefor the man ualcontrol and operation of the slide. jThe outwardly bent portion 11 forms a shoulder or stop to limit the downward movement of the slide 9, and at the same time it positions-the handle 12 away from the pipel so as tobe ireadily operable. In the absence of the hood next to be described, this shoulder engages the upper edge of the strap 2 whereby further displacementdownwardly is prevented. The hood, of above made, 'comprises essentially a fanwhich' cursory mention is shaped metallic top 14, the diverging edges 15 of which are approximatelyin radial planes of the stove pipe 1, when operatively assembled. The outer edge 16 is preferably arcuate, making the top 14 thereby alsegment of a circle. The inneror vertex end of such top is cut away upon a circular line 17 to register with the inner edge of the strap 2. Preferably atthe intersection of such arcuate line 17 and the radial sideedges15,

are secured as by rivets;.18, angular pieces or hooks 19 which bend downwardly and are adapted to take into the slot 5 to removably support the hood and retain the same against lateral displacement.

Preferably integral with the top 1 1 of the hood are its depending and preferably plane sides 20, 20, of triangular shape with one vertex registering with the point of intersection of the outer arcuate edge 16 and the respective radial edge 15 of the top. The inner edges 21 of such triangular-1y shaped sides 20 are substantially vertical, as shown best in Fig. 1, and adapted to meet and en gage the cylindrical surface of the pipe 1 along longitudinal elements thereof.

A segmental collar 22 inwardly connects the lower, inner vertices of the sides 20, being attached thereto by rivets 23 or the like. This collar is curved to engage the convex surface of the pipe when in operative position, and the moment of inertia introduced by the weight of the hood tends to rotate the same about the angular pieces or hooks 19 as an axis, such moment being balanced into stable and static equilibrium by the reaction of the strip 22 bearing against the pipe, thereby holding the hood in position. The triangular shape and arrangement of the sides inclines the top 14. downwardly as it projects outwardly by virtue of which rising vapors will be deflected inwardly upon being intercepted by the hood.

lVhen the hood is in operative position, the shoulder 11 of the slide 9 engages the inner edge of the hood top as shown in Fig. 3.

The removal of the hood is efi'ected by first sufticientlv raising the slide to disengage the hood; then lifting the hood, the hooks 19 disengage the strap 2, and the hood can be removed entirely from the pipe.

The operation of the device is evident and self explanatory. The hot gases, odors, and so forth which rise from the stove are intercepted by the hood and deflected inwardly as already stated. \Vith the slide 9 open, the gases pass on into and up the stovepipe. The presence and probably the inclination of the hood prevents the down draft of cold air into the stovepipe which would interfere with the draft of the stove. The slide is provided for use when it is desired to regulate or close the vent into the pipe, and more especially when it is desired to remove the hood entirely. It may here be stated that the action of the gases as above stated produces an inward current which will draw into the stove pipe other gases than those which would normally use and be intercepted by the hood.

In order to insure sufficient frictional engagement of the slide 9 with the slideways 8, I double back the edges 24- of the slide designed to slide therein, as shown in Fig. 5. The. expansive tendency of such structure retains the slide in frictional engagement with the slideways, as desired, and if in the course of time the expansive tendency may decrease, the doubled-over portion may be spread again with any suitable tool.

Having thus described the invention, what Iclaim is:

1. The combination with a pipe having a lateral aperture, of a strap mounted on the outside of said pipe adjacent to said aperture having a portion at right angles to the length of the pipe and spaced therefrom, a slide for said aperture working between said strap and pipe, and. a hood having hooks adapted to detachably take into the slot between said strap and pipe on opposite sides of said slide.

2. The combination with a pipe having a lateral aperture, of a strap mounted upon the outside of said pipe with a portion extending at right angles to the length of the pipe and spaced therefrom, a hood having a top and depending sides, hooks at the upper edges of the sides of said hood adapted to take into the slot between said strap and the pipe, and a strip connecting the lower edges of said sides of the hood and adapted to engage the pipe.

3.

4. The combination with a pipe having a lateral aperture, of a strap mounted upon the outside of said pipe adjacent to said aperture having a portion at right angles to the length of the pipe and spaced therefrom to form a slot between said strap and pipe, a hood having hooks adapted to detachably take into the slot between said strap and pipe near the ends thereof, a slide for said aperture in the pipe working between said strap and the pipe and having stops one above and the other below said strap, and a handle for said slide projecting above said strap and hood.

5. The combination of a pipe having a the pipe, a hood having hooks adapted to detachably engage saidstrap, stops for said slide above and below said strap, and a handle above said hood for operating the slide.
