WATER HEATER.
Application med August 8, 1828. Serial No. 128,870.
This invention relates to means for heating water, andmore particularly to means for electrically heating water -for domestic purposes.
It is an object of the invention to produce a neat appearing compact heatingll device at moderate cost which is attachab e to existing boilers or-water containers.
It Iis a further object of the invention to lo lproduce an electrical heating device with a plurality of heating units which are arranged to closel contact with water containers but whic are removable therefrom for the purposeof repair or the substitution of new units for old or burned out units.
Another object of the invention is to s0 arrange the heatin units with respect to the heater in genera that in the event that replacementv o f unitsis necessary they may 2o be uickly replaced by a person of average inte igence or mechanical or electrical skill without employing the services of a plumber as the arran ent is such that it is not necessary to 'smantle the heater or to shut oif the water supply during the replacement of the units.
It Iis an object of the invention to so ar-l range the heating units with respect to the water tubes or containers'as to present to the containers the maximum of heat transmitting surface consistent with the construc-- tion thereof, to thereby gain in heating eiliciency and to prolong the life of the heating elements or units by rapid conduction of the heat to the tubes.
A still further object ,of the invention is to produce a heater of the above class having a plurality of heating units therein of Vsuc arrangement that the absence of one or more units or the inabilit thereof` to function need not prevent the eater in general'from perfo at least a part of its function even thoug the time required to heat a given quantity of water may be somewhat longv er according to the unit or number of units absent or inoperative.
Other objects of the invention will be fully understood from a description of the drawinand the claims hereinafter given.
f the drawing. Figure 1 representsy a view of a domestic boiler the invention applied'thereto.
F' 2 1s an enlarged viewioi the heatevioe partially broken away and par- Il y in'wm Figure 3 is a side view of the heater y .shown in Figure 2 the casing being shown 1n section for clearness.`
Figure 4 1s a section on the line 4.--4 Figmie ferring to the dra 2 H The drawing herewith. ustrates the invention in one of the many forms in which it may be used, and for the purpose of explanation it is shown herein as applied to a boiler such as is commonly used in households for heating water for domestic purposes.-
It will be understood however that it ,is
not the intention to limit the invention to theA precise construction and arrangement shown as changes niight be made therein without departing from its s irit andscope'.
In the present instance t e invention is applied to a well known house boiler or tank 10 which is or may be provided with the usual supply anddraft pipes and which has the circulation pipes 11 and 12 coupled togetherby the heater 13 so that the water assin through the heater will be drawn rom t e bottom of the boiler and discharged intothe top thereof to be drawn upon as wanted through the pipe 14.
The heater proper comprises an upper and a lower manifold or hollow head 15 and 16, respectivel whose interior chambers are connected y a row of parallel atftubes 17, the number, size and ength of which dending upon the capacity required of the eater.
The tubes 17 are arranged in spaced relation s'o as to enable the insertion of heating units between them as will be presently explained.
Partially lsurrounding the tubesvl'( and frictionally held thereto are the clips 18 and 19 to'which are secured the longitudinal bars 20 and 21 by means of the screws 22.
Secured to the bars 20 and 21 by the screws 23, and insulated therefrom, are the yoke members 24, 25 and 26 Ywhich serve to re- Y c eive the screws or other means by which the It is preferred to arrange the heating units in two or more b anks or series A and B and .for the sake of explanation two banks are shown hereinso that each unit of the upper series has one end of its wire secured to the yoke 24'and the 4other end secured to the yoke 25, while each unit of the lower series has one end of its wire secured to the yoke 25 and the other end secured to the yoke 26.
lIt will also be understood that one bank or series may 'be of greater or less resistance than the other by which arrangement three heats may be obtained b the use of a well known switch S indicate in Fi ure 1 of the drawing, arranged to cut in eit er the high or the low resistance unit or both together to get the maximum heat or capacity.
The said units are of simple structure being composed of a central slab of suitable insulating material 30 preferably mica, which is wound with a resistance wire lor ribbon 31, and two slabs of insulating material 32 and 33 arranged one each side of the central slab, the said slabs being secured to ether in any suitable manner.
he resistance wire or` ribbon 31 of each unit is arranged to extend therefrom so that itskends maybe connected to the proper o es.
y These units are of such a width depth and length as to permit them to be inserted in the space between the tubes 17 and to iit snugly therein with their side slabs in close contact with the tubes s'o that the greatest possible heat transmitting surface may be frictionally sothat they presented to the tubes.-
It will be understood that it is preferred that the heating units shall be held in place may be easily removed'one at a time without the use of instruments or tools other than a screw driver with which to loosen the screws securing the ends of the resistance wire to the yokes.
Surrounding the tubes 17 is the casing 35 va' portion of which may be permanently l attached to the heads 15 and 16 and having the vfront portion hinged' at 36 to form a door 37 as a means of access to the interior thereof. when it becomes necessary to repair 'or replace the heating units. As'will be clear the casing 35-37 constitutes a cylindrical jacket, closed-at its ends by the manifolds 15 and 16, said jacket serving with the manifoldsto inclose the tubes and heat-' ing units so as to confine the air immediately surrounding-the latter and thereby prevent the heat fromthe units being' dissipated tainers or tubes were placed, withouty disturbing the water syscomprising a pair of hollow one-piece end manifolds, one having an inlet adapted to be connected with a supply pipe and the other having an outlet adapted t0 be connected with a delivery pipe; a plurality of tubes directly connected at their ends with said manifolds and connecting the interiors of the latter and electric heating units arranged between said tubes.: L
2. A heater ,of the character' described comprising endmanifolds, one of which is u provided 'with aninlet adapted to be connected with a supply pi e and the other vwith an outlet adapted to e connected with a 'deliver pipe; a plurality of tubes connecting .t e interiors of said manifolds; a plurality of electric heating units disposed between said tubes; tube-holdng and conning clips embracing and supported by said tubes; binding post supportin members carried by but insulated from said clips, and a sheet metal jacket co-operating with the end manifolds to inclosethe tubes, heating units, clips and binding post supports.
3. A heater of the character described comprising a pair of hollow one-piece end manlfolds one having an inletl adapted to be connected with a supply ipe and the other having an outlet adapte to be connected with a delivery pipe; a plurality of tubes directly connected at their ends with said manifolds and connectingthe interiors of the latter; electric heating unitsarranged between said tubes, and a sheet metal tubular jacket surrounding and inclosing said tubes telescopically engaged at its opposite ends i with said manifolds by which 'latter it is positively supported in positionv against displacement, said jacket being circular in cross-,section and including a segmental body portion that measures more than 180 degrees and less than 360 degrees circumferentially sov that it holds itself in position upon' said manifolds and includin mally closed door segment mova ly connected with said body portion.
4. A heater of the character constructed in accordance with claim 3- and described l wherein the movable door section is hingedly connected with one side of said segmental body ortion.
5. heater of the character -described comprising a pair of hollow oneiece end manifolds, one having an inlet a apted to.
be connected with a supply pipe and the other having an outlet adapted'to be connected with a delivery pipe; a plurality of tubes directly and permanently connected at their ends with said manifolds and connecting the interiors of the latter; electric heating units arranged between said tubes and a. cylindrical sheet metal housing jacket coniy pletely inclosing said tubes andheatinglr units, said jacket being separably connected with and normall supported against displacement by sai end manifold but with provision for removal without disturbingr the normal condition of the other parts of Vthe heater.
