Definitions

• a stove as well as a method and a device for manufacturing and mounting fire-places.
• the present invention relates to a method for manufacturing and mounting fire-places, e.g. stoves, a device for mounting such fire- places as well as a stove.
• Fire-places e.g. masonry stoves
• Stoves are thus known since the eighteenth century and are very efficient sources of heat.
• the object of the present invention is to further simplify the manufacture and mounting of masonry fire-places in general, particularly stoves, in order to be able to install it without the expert knowledge of a stove constructor.
• a fire-place is manufactured in two halves in a factory, preferably from blocks according to e.g. the Swedish patent cited above, and subsequently the fire-place halves are transported to the place where they are to be mounted and installed. Since each fire-place half e.g. in the case of stove-halves typically weighs 800-1000 kg, one has so far cosidered it as impossible to carry such heavy units into a residence and to mount one of the units on top of the other.
• the present invention suggests a surprisingly simple solu ⁇ tion to this problem, which so far has been considered insoluble.
• the invention accordingly involves a complete novel concept in the present technical field.
• the device according to the present invention thus comprises a lifting frame on wheels, by means of which frame the upper fire-place half is lifted and adjusted on top of the lower fire-place half when mounting the fire-place.
• This operation has, as mentioned, so far not been considered feasible to accomplish in residences, since when transporting such heavy plants trucks of various types have been used, which can not perform such a lifting indoors.
• the device according to the invention can, during the transport, be used for lifting the fire-place halves from one level to another, e.g. from the ground up on a bridge a few fast steps above the ground.
• each fire-place half is provided with lifting means including a metal frame, which is attached around the outer edges of the fire ⁇ place half and in which the lifting frame is intended to engage.
• This metal frame can include iron profiles at the top face and the bottom face of the fire-place half along the outer edges as well as bars exten ⁇ ding from the top face to the bottom face of the fire-place half at the corners of the fire-place half, which bars are threaded in order to attach the profiles of the top face and the bottom face to each other by means of screwing. In this way the strength of the fire-place half is improved too, which may be of importance for reducing the risk of damages during the transport.
• said bars extend in holes through the corner regions of the fire-place halves inside the outer surfaces. Said holes are preferably somewhat larger than the diameter of the bars such that the bars can move through the holes e.g. during temperature fluctuations without producing stresses.
• an insert to produce hot water is placed inside a stove, in its central flue at its rear wall, above its fire-place.
• Said insert presents an inlet and an outlet, which are designed to let water in and out respectively and connected to pipe lines, which extend through the wall of the stove.
• Fig. 1 shows a stove according to the invention, in a longitudinal section
• Fig. 2 shows a section along the plane B-B in Fig. 1;
• Fig. 3 shows an embodiment of a lower stove-half, which is provided with lifting means according to the invention as well as the l fting member used in the invention;
• Fig. 4 is a lateral view of an embodiment of the device according to the invention.
• Fig. 5 is a top view of the device in Fig. 4.
• Fig. 1 shows in a longitudinal section a stove having a fire-place
• Fig. 2 shows in cross-section the various flues 14,15,17 and 19 in the stove for directing the fluegas in upward and downward directions respectively in the stove.
• the stove is manufactured by pre ⁇ fabricating the lower and the upper stovehalves, preferably built by blocks, as has been mentioned above, the lower stove-half preferably extends to and includes the course which forms the shelf 16, see fig. 1.
• the upper stove-half preferably extends to the course for connection to the smoke flue 1.
• Fig. 3 shows an embodiment of the lower stove-half, which thus is made of blocks.
• This stove-half is provided with lifting means in the form of a metal frame, which is attached around to the outer edges of the stove-half and in which a lifting member is adapted to engage to lift the stove-half to its position in connection with its mounting and installation.
• This metal frame which is applied in connection with the manufacture of the stove-half, comprises iron profiles 18,19,20,21,22 and 24, which are arranged in a square at the upper and the lower faces of the stove-half along the outer edges. At the corners of the stove- half vertical bars 26,28,30 and 32 extend between the profiles at the upper and lower faces.
• said bars extend through holes made in the corner regions of the blocks, inside the outer faces of the blocks. Said holes are then somewhat larger than the diameter of the bars, such that the bars are movable in the holes without producing stresses.
• the metal frame shown in fig. 3 also improves the strength of the stove, the risk of damages in connection with the transport in this way being decreased.
• the yoke shown in fig.3 is secured by screwing to the upper face of the stove-half.
• the lifting yoke is substantially H-shape and it is secured by screwing with stems 34,36 of the H-shape extending along two opposite edges of the stove- half, i.e. stem 36 is secured above profile 18 and stem 34 above profile 22.
• stems 34 and 36 Between the stems 34 and 36 a transversal web extends in the form of two parallel! separated girders 37,38 provided with a transversal pin 40 in the middle of said web, for hooking a lifting cable 41.
• the device shown in fig. 4 and 5 is used.
• It mainly comprises a substantially U-shaped base having such dimensions that a stove-half, which is schematically indicated by 42 in fig. 5, can be pl ced inside the U-shape with legs 44,46 of the U-shape disposed on each side of the stove-half.
• the base is supported by two freely rotat- able castor wheels 48,50 at the free ends of the legs 44,46 of the U- shape as well as a third freely rotatable castor wheel 52 at the center of web 54 of the U-shaped base, which web connects said legs.
• a vertical lifting portal is disposed, which comprises two posts 56,58, which are connected by a transversal girder 66 at the upper end.
• a frame means 60 extends upwardly to the upper portion of the lifting frame, where it by means of lateral pieces 62,64 is connected to the posts 56,58 of the lifting portal.
• the lateral pieces 62,64 are mutually connected by transversal girders 66,68 and 70.
• the frame means 60 comprises two parallel! girders 72,74.
• a manual hoist is disposed, schematically shown at 63 in fig. 4 from which a cable runs via rollers 76 and 78 disposed at the upper portion of the lifting frame. From the roller 78 the cable end 41, which is provided with a suitable lifting hook 43, runs downwardly to be hooked on the lifting pin 40 of the lifting yoke, mounted on the stove-half to be lifted (see fig. 3) and by means of which the stove-half can be lifted by the manual hoist, provided with a lock.
• the lifting frame preferably can be adjusted in a vertical direc ⁇ tion, the frame means and the posts of the hoisting portal being tele- scopically displaceable inside each other with possibility to be locked in various positions.
• the lifting frame preferably also is foldable to facilitate the transport from one mounting place to another and to facilitate the displacement of the frame through the door of an apartment room.
• the transport of the stove-halves in this connection preferably is accomplished by means of a small truck.
• the stove is prefabricated in two halves in a factory, the pre- fabrication possibly being complete, i.e. the stove-halves are provided with tiles or other coating or painting. Subsequently the stove-halves are transported to the place where the stove is to be mounted and installed.
• the lifting yoke is mounted on the lower stove-half and by means of the device according to the invention the lower stove-half is lifted and fitted into its correct position by displacing the wheel - supported lifting frame to the desired position.
• the lifting frame can be displaced in any desired direction and thus the stove-half can be adjusted to any desired posi ⁇ tion.
• the wheels can preferably be locked against rotation as well as turning during the lifting operation itself.
• the l fting yoke is undscrewed and the upper stove-half is provided with the lifting yoke, whereupon this stove-half is lifted by means of the device according to the invention with said device posi ⁇ tioned beside the lower stove-half such that the upper stove-half will be at a distance above the lower stove-half.
• the device carrying the upper stove-half is rolled to such a position, that said upper stove-half is in the correct position above the lower stove-half.
• a suitable mortar is applied to the surfaces of the lower and the upper stove-halves, which face each other, and thereafter the upper stovehalf is lowered to its definitive position on the lower stove-half.
• the lifting yoke is removed from the upper stove-half, the device is removed and the stove is connected to the smoke flue.
• the lifting device preferably is placed on e.g. a rigid plate, if the installation takes place in a room having easily damaged floors, to distribute the pressure of the wheels of the device in this way and consequently avoid damages to the floor.
• the invention in the preceding has been described in connection with the application to a stove, it is applicable to (masonry) fire-places in general.
• the device according to the invention can also be used for transport and installation of other heavy items in e.g. rooms.
• an insert 4 for heating water can be disposed inside the stove in its central flue 80 at its rear wall 82 above fire-place 10, as is shown in fig. 1 and 2.
