Description

DCC 12, 1944. J. 'l'. KAMoWsKl THERMAL INSULATING JACKET Filed Sept. 2 1, 1945 Jnaepfh Patented- Dec., l2, 1944 UNITED ISTATES PATENT oFFlcE THERMAL rNsULA'rrNG JACKET Joseph T. Kamcwski, Nanticoke, Pa.. Application September 21, v1943, Serial'No. 503,273
` z claims. fol. 154-44) The side wall portion B of the novel cover A may be constructed of a sheet I of canvas or other suitable pliable material, and coated or impregnated, if desired, with mildew-inhibiting and/or fireprooilng materials. It is preferably of one piece construction and adapted to extend l wholly around the side of the tank, being longer than the length of the outer circumference of the tank, to accommodate for heat insulating material carried by it, and being higher than the height of -the tank, also because of insulating ing cover or jacket for conventional hot water storage tanks. v l
Another object is to provide a cover for the purpose mentioned, which will insulate not only the sides of the tank, but the top and bottom portions as Well. y
Still another object isto provide a cover, as last described, which is not permanently attached to the tank, but which will not sag underits own weight.
Other objects and advantages of this invention will be apparent during the course of the following detailed description of the invention, taken in connection with the accompanying drawing, forming a part of this specification, and in which drawing:
. Figure 1 is a perspective view, showing the novel cover applied to a hot Water tank.
Figure 2 is an elevation of the side wall cover portion, `spread out.
Figure 3 is a horizontal section`,-sub'stantial1y upon the line 3-3 of Figure 2.
Figure 4 is a horizontal section through a tank and the side Wall cover portion applied thereto.
Figure 5 is a top plan of the two sections making up the top cover portion.
Figure 6 is a bottom plan of the two sections I making up the bottom cover portion.
Figure 7 is a view; similar to Figure 6 but with the two sections united.
Figure 8 is a fragmentary vertical section of the side wall'cover portion.
Figure 9 is a fragmentary vertical section of the side wall and top cover portions applied to a tank.
In the drawing, wherein for the purpose of i1- material which preferably projects above and below the horizontal planes of the tank ends, as will be more fully explained. In order to easily secure and remove the side wall portion B to and from the tank E, it is preferred to employ socalled zippers along the vertical ends II and I2 of the portion B. l,
Extending from the top and bottoni ends of the main part I3 o1' the portion A, are a plurality of flaps I4 and I5, truncated conical 4in general shape, with the smaller ends of iiaps It formed into hems I5 through which extend aV cord I6, The smaller'ends lof Yiiapsv I5 are similarly providedwith hems and a draw-string or the like.
or cord IE, as shown in Figure 2. 'KIVhe function of this means will be explained later.
Carried by the portion A (exclusive of the flaps I3 and I4) is suitable heat insulating material I`I,'as so-called rock Wool disposedwithin the spaces between the sheet I0 and an inner sheet I8 which may be of any suitable pliable material.- The material of the sheet I8, may be formed into loops I9 as in Figure 2 and sewn longitudinally to the sheet I0, so that a plurality of pockets'- 20 will be formed in which the insulating material I1 may be placed. The ends of the pockets' may be closed as by securing the upper and lower ends of the sheet I8 to the sheet I0, such as at 2l.
lustration is showna. preferred embodiment of the invention, and wherein similar reference chracters designate corresponding parts throughout the several views, the letter A may designate the novel cover or jacket as a Whole, the letter B the side wall portion thereof, C the top wall portion, D the bottom wall portion, and E a conventional hot water storage tank.
Since most hot water storage tanks have a conduit (or sometimes two) extending outwardly from the side wall, the sheet I0 must be provided with a suitable opening or openings therefor. Such opening comprises a pairof semicircular cut outs, or recesses 22, one in each of the vertical ends II and I2 for each conduit. Of course, this entails the use of several runs of zippers, as is obvious.
The top Wall portion C comprises two semicircular sections 25 and 26, as shown in Figure 5. Each section has preferably a top wall 21, bottom wall 28, curved outer wall 29 and flat inner wall 30. These walls may be of canvas or some of them may be of plywood, as desired, but the several walls are suitably secured together to form a pocket 3| containing suitable heat-insulating material 32.
Radially-extending reinforcing ribs 33 may be provided to brace the sections 25 and 25 and semi-circular recesses 24 and 35, provided in their flat inner walls 35 to accommodate the usual conduits extending from the top of the ordinary hot water storage tank. Of course, the two sections 25 and 25 when arranged with their :dat inner walls 30 in abutment, constitutes a ilat cylinder with an outer circumference substantially similar to that of the tank E.
The bottom wall portion. D is somewhat like the portion C, but may be thinner and not be provided with ribs. Since but one conduit usually extends from the bottom of the tank E, there is but one semi-circular recess 40 in each section 4| and 42 oi' the portion D. In order to attach the two sections 4I and 42 together to form a ilat cylinder, suitable hook and eye means 43 may be provided on the outer (lowermost) faces 44 of the sections 4I and 42. Where legs extend from the lower face of the bottom wall of a tank, the sections 4I and 42 may be slotted as at 45 to accommodate such legs.
The hot water storage tank E is shown as having a cylindrical side wall 50, top or end wall I and bottom or end wall 52 with a conduit 53 extending outwardly from the side wall 50, two conduits 54 and 55 from the top wall 5I and one conduit 56 from the bottom wall 52. Three legs l 51 (the conventional number) are shown as supporting the tank.
In assembling the novel cover or jacket A, the top wall portion C is rst placed in position upon the top wall 5I of the tank and then the side wall portion B placed in position, so that the cut-outs or recesses -22 accommodated the conduit 53 and the flaps I4 at the upper end thereof, being pliable and free of heat insulating material, may be disposed upon the portion C whereupon the drawstring I6 may be manipulated so as to draw the ilaps I4 together, with the drawstring I5, encircling the conduits 54 and 55, and the ends of the drawstring I6 ilrmly tied and tucked under the flaps I4.
Next, the bottom wall portion D may be posi tioned to cover the bottom wall 52 of the tank E and when the hook and eye means 43 is employed, the two sections 4I and 42 will be held together, encircling the conduit 56 and held frictionally thereto. The three ilaps I5 may now be positioned to accommodate the three legs 51 and then carried under the tank E and portion D whereupon the drawstring I6 thereof manipu- 55 asoman lated to draw the flaps Il together and the drawstring then tied and tucked under the flaps as explained. The drawstring Il, ofcourse, encircles the conduit 55,
The greater portion of the weight of the portion B is upon the portion C, but the latter is reinforced by its walls and ribs, and the drawstrings l5 and hems I5 maintain the flaps I4 and I5 taut over the portions C and D, so that a neat, trim appearance is provided.
From Figure 9 it will be seen that the heat insulating material II extends upwardly beyond the horizontal plane of the upper face of the top wall 5I of the tank E, so that there is complete insulation coverage of the tank at the juncture of the top or end wall 5I and side wall 50.
When the portion B is disposed about a tank E, it will appear, in horizontal cross section substantially as in Figure 4.
Various changes may be made to the form of the invention herein shown and described without departing from the spirit of the invention or scope of the claims.
What is claimed is:
1. In a heat-insulating jacket for a hot water storage tank having a conduit extending from an end thereof, a side wall portion having end aps, with heat insulating material over the inner face of said side wall portion, said flaps being free of said heat-insulating material, an end wall portion, comprising two sections extending about that part of said conduit nearest said tank and also extending to the inner face of said side wall portion, said end wall portion being provided with heat insulating material, said ilaps extending over a portion of the outer face of said end wall portion toward said conduit, and means for drawing said flaps together and maintaining them taut over said part, said means encircling said conduit, and comprising a drawstring extending through' the free ends of said flaps.
2. In a heat-insulating jacket for a hot water storage tank having a side wall, an upper end wall and a conduit extending from said upper end wall, a side wall portion embracing the side wall ot said tank, provided with heat-insulating material disposed over the surface of said side wall portion, and truncated conical shaped end ilaps extending over a part of said upper end wall adjacent the edges thereof, and means for maintaining said ilaps taut over said part, said means encircling said conduit, and comprising a drawstring slidably extending through the free, narrower ends of said flaps.
