My invention relates to improvements in heaters for the purpose of utilizing radiated heat from a stove pipe or other products of combustion conduit. It is particularly adapted to application to domestic heaters, such as household stoves, which are used with solid or gaseous fuel for heating of residences or other buildings, and generally comprises a surrounding preferably ornamental shell adapted to conceal the usual stove pipe between the stove and the flue connection.
In my present improvement I have provided an improved wall plate and two-piece companion units for both straight and elbow sections of the stove pipe; also improved means for mounting the same around the stove pipe, particularly in connection with an adjustable mounting bracket strap or collar; also means for longitudinal adjustment and interfitting connection between the connected ends of the several units; means providing for easy separation, location and tightening of the supporting collars, and for attachment thereto of the perforated covering shell; means for mounting and securing the covering shell at diagonally opposite "or at each of the four equally spaced corners thereof, and various other features of construction and improvement, as shall be more fully hereinafter described.
The present invention involves various features of improvement over the construction shown in my prior application Serial No. 665,969, as shall be more fully hereinafter described.

Fig. 10 is a face view enlarged showing a group of perforating openings through the side wall of the covering shell;
Fig. 11 is a detail sectional view on the line 5 XI-XI of Fig. 10;
Fig. 12 is a partial detail view, showing the rib.
Referring to the drawings, 2 represents the usual stove pipe which ordinarily extends from a stove through the open space of a room, and to an upper outlet flue connection through the wall.
It is provided with the usual straight and elbow joint members, not herein illustrated, and at its upper end it is designed to pass through the middle opening 3 of a wall bracket or plate 4. The latter is preferably of rectangular construction, flat as to its main outer face and provided with inwardly extending flanges 5 for contact when held in position by screws or the like, extending through the several openings 6 in the wall.
Bracket 4 is of comparatively light sheet metal with the middle clearance opening 3 punched out by suitable dies and provided with extending attachment flanges '7 extending at right angles outwardly from the flat face of the base.
Such flanges are in pairs, one member being disposed at right angles to the other, whereby to receive against it the correspondingly disposed flat wall portion of the casing section B. These are generally similar to the construction of my prior application except that each section, constituting one main half of the entire covering, is rounded at the corner as indicated at 8, between the diverging substantially flat members 9.
Each of such members terminates in a partially rounded edge portion 10 so that, when the two sections are placed together, as in Figs. 2 and 3, they will overlap and underlap respectively at opposite corners. As clearly shown, the flat side portions 9 of the angle sections are provided with perforating circulation openings 260, preferably arranged transversely across the width, in repeated ornamental pattern formation throughout the entire length of each section, and at each 45 of the four sides, when the sections are in position.
The sections are mounted around the stove pipe 2 by means of the embracing band 11 which may be tightly secured atany desired point or points longitudinally of the stove pipe by means of a tightening screw or bolt 12 engaging outwardly turned flanges 13 and preferably with a bolt head and nut receiving washer 14. Such washer as shown is preferably square, fitting into the angle corner as at so as to stiffen the flanges 13 in tightening the device. By such construction and arrangement the band may be appropriately located at any desired position or positions on the stove pipe for interengaging connection with the perforated cover sections.
At the opposite corner position, the band 2 is provided with the outwardly extending brackets 16 of general right angle formation but rounded at their corner portions to a curvature corresponding to that of the curved edges 10 of the cover sections.
The flat portion at each side of the rounded corner portion of each bracket is preferably provided with punched out tangs or lips 21 adapted to engage through a pair of the openings 26a and to be folded over thereon in clamping. engagement, when in registering overlapping position as in Fig. 3. By such construction the meeting edges of the sections are positively clamped and fixedly held, together with the additional screws 23 at each side of each opposite corner portion, engaging holes 24 through the rounded corners 8 and 10.
In adjusting one section endwise to another, care should be taken to bring the perforating openings 26min registering coincidence, for continuance of the design throughout the entire length.
Each straight with longitudinal reinforcing outwardly extending ribs 25 which not only stiffen and brace the construction but add greatly to its ornamental appearance in connection with the fiat perforated panel sections and the rounded corner portions. By such arrangement the entire covering when applied is very strong and substantial and forms a continuous casing with a continuous series of air circulation openings.
One especial advantage of making the sections in this manner is that they may be readily adjusted to each other as by lengthening or shortening to adapt themselves to the space to be covered, merely by bringing the transverse rows into register and then securing thesections in place. If desired, the ribs 25'at one end of each section may be slightly tapered and reduced inwardly so as to ensure interi'ltting engagement beneath the next adjacent telescoping section, but the sheet metal being so comparatively thin and the variation so slight, a. very slight degree of reduction and taper is sufficient.
I show in Fig. 12 a diagrammatic View of thexrib 25 of maximum size at a tapered at b, and of re-' duced size at c for slidinginterfitting engagement with the inner groove of the rib of an outer section, when brought together.
It will be understood also that the elbow sections are to be made conformably to the same cross sectional design and formation as the straight sections, and applied in the same general manner, merely by bending their opposite corners and their terminaledges in rounded form, for similar interfitting engagement with each other and with co-operating connection with the ends of the straight sections.
I show in Figs. 8 and 9 my improved elbow section coveringC, adapted toform telescoping con-' section is preferably provided.
tinuations of the straight sections B. These are made of two similar side sections 26 and 27, an outer rounded section 28 and an inner rounded section 29, each having a middle perforated face adapted to form an extension of the middle fiat portion 9 of the straight section B. Likewise each corner portion of the elbow section is rounded conforniably, one end of the elbow section being sufficiently small to the extentof the gauge of the sheet metal, to make a close interfitting engagement within the end of an adjacent straight section. The other end, alternately, embraces the end of a straight section, as will be readily understood, if necessary.
The diagonal rounded corners of the complete elbow unit are connected by screws 23a and the intervening rounded corners are welded together as at 30. By such construction side member 26 and the inner curved section 29 are combined in one piece, and side member 27 and outer curved section.:28 are also in one piece, so that when both are assembledzand. connected by the screws 23a the complete elbow member. is erected around'the stove pipe.
The straight sections being fixedly. held on the pipe by their strap brackets, thus form ample connecting and holding engagement with the elbow sections, for continuous location. However, one or more strap brackets may be used for the elbow sections; located beyond the bend, in the same manner as with the straight sections, already described.
The elbow sections are provided with ribs 25a like ribs 25 of the straight sections, slightly tapered as at 25b for telscoping engagement. The side faces between the perforations are radially ribbed as at 3-1 and the rounded corner portions 8a are radially. ribbed asat 32, preferably tapering from their middle towards their terminals and providing a continuous annular abutting edge: Such ribbing provides strengthening stiff-- ness and is also ornamental in the general design.
The straight sections-B asshown are provided at intervals with the screw holes 24; These are located at regularly spaced intervals so that in mounting the sections on their supporting brackets such connections may be made through the double thickness corners into the brackets, and by the flexible lugs 21 throughopenings 26a, at varying positions, dependent on the entire length of stove pipe to be covered. and without necessitating close adjustment as to lengths of the sections. I thus provide for a considerable degree of lengthening or shortening of the attaching pointsof the final section in completely covering the pipe and: thus-avoid the necessity of cutting. As-will be obvious, the cutting of the.
straight sections inthe field-or at the location of application, is ordinarily diih'cult without disturbance or bending of the thin sheet metal especially at the corner and rib portions, such shearing being thus rendered unnecessary.
For the purpose of closelyconnecting the outer curved overlapping edge 24 to the inner telescoping edge ofthenext' longitudinal section the perforations 26a of both are first brought into register; The inner edge may be then. punched through holes 24 for location of corresponding holesfor connection by metal-to-metal screws, thus holding bothv curved rims. in tight close engagement.
InFigs. 3iand 6, I show an improved construction of clamping bracket strap for variable-a-t-= tachment to the: stove. pipe 12: and for co-operating engagement with the surrounding coyiering sec tions. Thus in Fig. 3 the clamping strap 11 already described is provided at opposite diagonal corners with the outwardly extending brackets 16 having the corresponding screw holes 231) for attachment of the overlapping and underlapping rounded corner portions 10 by screws 23. The lugs 21 as stated are passed outwardly through perforations 26a and bent over into clamping engagement therewith as shown.
In the construction of Fig. 6 the brackets are located at each of the four corner portions around the strap 11 which is connected by bolt 12 in the manner above described, firmly holding it at any desired position around the stove pipe 2. Instead of individual brackets 16, I utilize a continuous band 16a, which at three equally spaced points is bent inwardly as at 19c and spot welded or riveted to the band. The terminals of the continuous bracket member 16a are brought together at the remaining quarter distance location, one end being spot welded or riveted to theband as at 1%. The other end is also bent inwardly as is the flange 19 of Fig. 4 and provided with openings 33 for reception and clamping engagement by the tongues 21a, forced outwardly from terminal 191) like tongues 21.
By such construction the entire strap section may be opened up by removal of bolt 12 and outward bending of the corner bracket 16a, as indicated in dotted lines in Fig. 6. Each corner bracket in such construction is provided with the tongues 21b adapted to interengage with openings 26a, as stated.
With either construction the generally rectangular pipe covering is capable of being easily and quickly applied or removed to or from the stove pipe sections, either in the straight or elbow portions, with facility for telescoping engagement and providing a substantially continuous smooth surface exposure.
It is desirable that the covering shells of the invention may be made in various color schemes to correspond with the ornamental coloring of the stove itself, or in harmony with other furniture, wallpaper, etc., as by painting, enameling or other well known means.
In Figs. 10 and 11 I show a modified construction in which the main circulation openings 260. are of modified construction, the metal being forced outwardly beyond the main surface as at 34, presenting an annular face 35 around each hole. With such construction the entire section may be subjected to a grinding or buffing operation whereby to remove the plating, paint or enamel around each opening, leaving a narrow annular band of contrasting color, thus adding to the general ornamental effect, with a certain degree of stiffening result.
It will be understood also that the elbow sections are to be made conformably to the same cross sectional design and formation as the straight sections, with corresponding perforations on all four sides. They are applied in the same general manner, merely by bending their opposite corners and their terminal edges in rounded form, for similar interfitting engagement with each other and with co-operating connection with the ends of the straight sections.
If desired, it will be readily understood that the four several wall members of either the straight or elbow unit members may be of separate individual pieces. In such case, instead of permanently connecting two adjacent walls, all of the walls may be assembled and held to each other and to their brackets, by the screw and lug attachments above described.
The entire covering shell is spaced beyond the stove pipe and utilizes its radiated heat by inducing an inward circulation of cool air at the bottom through the perforations, and a corresponding outward flow towards the top. The covering shell itself is comparatively cool and avoids direct contact with the hot stove pipe, thereby avoiding injury by burning or scorching.
The entire covering is self-supported by its mounting on the pipe, and thus any outside supports, guy wires, or the like are eliminated.
The construction and manner of operation of the invention will be readily understood and appreciated from the foregoing description. It provides a highly ornamental and very useful means for covering the stove pipe, with ample facility for adapting it to various lengths and sizes, and is easily applied or removed. The sections are preferably made in standard lengths for application, and, due to their elastic feature as to lengthening or shortening by the telescoping joint construction, may be used without the necessity of transverse cutting.
