WOLBERS HEAT UTILIZING COVERINGFOR STOVE PIPES Filed April 13, 1933 3 Sheets-Sheet 3 Patented Jan. 22, 1935 invention-relates to improvements in heaters for the purpose ofutilizing" radiatedj heat from astove pipe or other products of combus- 't io"n conduit. It is particularly'adapted to appli- "cationto'j'do'mestic" heatersf'sucn as household stoves; which muse with'solid' or"gaseous fuel for heating residences or other; buildings; In modern 'p'racticefitis'soinwhat usual to surround thefoi'dinarydomestic stqv'ef-with an ornamental casing, from" which the conventional stove" pipe usually passes upwardly through a rooxnio'r'c'ojnnection to a flue at a higher level.

In my invention I provide 'asurrounding pref erably ornamental shell; as hereinafter described, adapted if desired to conformto the style, orna' mentation, color,'etc. of the main stove covering, and to conceal the usual stove pipe between the stove and thfe fiue connection. "Iheprincipal useful functioh of such covering however,- is to provide-between it and the stove pipe a fsurro'und ing circulating =*channel' for additional heating and distribution of the heated air'ina room,- hallway-, f0r'the likel; g r Certain preferred embodiments of the invention' are illustrated ings, in 'whichi I l e y Fig; 1 is a'view inelevationshowinga continuous outlet stove pipe provided with my improvementr, f I 1 Fig. 2 is an 'enlarged'c'rcss sectional view on the line 11-41 of'Fig; 1; I Fig} 3 is aperspective'detail view showing adjacent connectingcorner portions oi the sectional covering; H I

I t c The usual stove pipe construction utilize's an elbow joint member 3 and one or more sections 4 of a straight stove pipe; connected int I usual manner and provided at the upper end 1th an outlet elbow '5, 'communicat'ng with thejflue 6, a ni g'; 1. v Tile pipegare covered with enclosing casingsections B and theelbow jointsl3jand15 are covered with the correspondingly shaped casing sections C,

co nfstructed'asihereafter described. 7

The sections B are made of twovgenerally anr traight sections of thes tove whenyused, and having gle-shaped piecesi'of comparatively thin sheet metaLibentat their middle to provide a corner "7 f'e'xtending rectangularly "therefrom, providing the diverging walls 858. 1 Such angle-shaped sec; tions are of suitable length and adapted to make abutting Qengagemen't', V with each "other, or are preferably )bentlinwardly at one end, as at 9",'-t o make sliding telescoping engagement {with the '[opposite'end oi the n'extsection, as in Fig.3.

Each such section, 'when brought together around the stove pipe, with another similarlse'ce tion, thereby providesa completebox -lik'efen closingf casing or'shelL with ample intervening spacef between'itiand the stove pipe 4 for upward circulationof gair "continuously around and between' thecstove pipe and such casing. .o 7 1) ,mr the purpose of fixedly supporting and hold i g'jthe boig-like'se'ctions in such spaced relation I utilize aseriesof clampingvbands 10 of sheet;metal, jheldo together by securing, screws or 7 bolts 11 throughterminal flanges'l2. Eaohband 10 is continuous and, of the proper length-teembracelth stove, pipe of any .deiinitediameter, suflicient clearance, for tightening pennanent clamping engagement.- e I p I afchflopposite side portion of the clamplO is provided with-an outwardly extending bracket D, togwhich theiouterlbox-like casing sections are secured 'each .su'ch ,fsection being preferably tached at its upper and lowerportion .byjholding screws 13, preferably metal to metal; Eachfhalf 'ofjf'the entiresection B is providedwithione' or more screw holes M, a and these are preferably spacedv apart vertically at standard dimension distancesijas gsay one inch, providinga number of adjustment spaces at eachend, SQth'atthe section may be out off where desirable or? necessary "to conform to the complete length of the stove pipe in application.

Screws 13 connect the outer shell sections with the vertical bracket walls 15 having receiving screw holes 16, as in Fig. 4,-for such attachment. The supporting brackets D are made of thin sheet metal from the blank shown in Fig. 5, having the middle inwardly extending tongue 17 adapted to be bent downwardly, at right angles on the dotted line and secured to band 10 by rivet 18.

The side wing portions 15 are similarly bent downwardly on the dotted lines 19, the end portions of the blank being deflected inwardly as at 20.

In such case the brackets D are formed to provide the continuously rounded vertical faces 15a conforming to the contour of the sections, with effective spacing adjustment. The brackets and sections are similarly connected by screws and are otherwise substantially the same as in the rectangular form, above described.

The construction and operation of the invention will be readily understood from the foregoing description. It may be applied to any existing stove pipe by application of the successive pairs of bands 10, which are amply flexible to permit opening around the pipe by removal of the nuts of screwsmr bolts,. 1 1, then bringing the ends togather anmit ighte'ning pla ce; ighe successive outer sections are then applied, so that the entire pipe becomes covered.
