3 Claims.

This invention aims to provide a novel means whereby sand may be heated, as is necessary in connection with building operations and the like. The invention aims to provide a simple structure which can be taken down readily and transported from place to place, the device, when taken down, being capable of being handled by one man.

A mechanic who abides by what is claimed, may make changes without departing from the spirit of the invention.

In the drawings:

Fig. 1 shows in end elevation, a device constructed in accordance with the invention;

Fig. 2 is a top plan wherein parts are broken away;

Fig. 3 is a longitudinal section wherein parts are broken away;

Fig. 4 is a transverse section;

Fig. 5 is a perspective View showing one of the members which form th transverse walls;

Fig. 6 is a perspective showing a portion of one of the base beams.

The device forming the subject matter of this application preferably is made of metal throughout. It includes a base B, made up of parallel beams I, of inverted U-shape, the beams being spaced apart transversely. Each beam I carries, near its end, a double-walled socket 2. The inner I edges of the sockets 2 are arcuate, as shown at 3, to receive a tubular combustion member 4, preferably circular in cross section.

The device includes end walls 5, each end wall being made up of oppositely disposed, alined parts 6, having curved edges 1, conforming to the cross section of the tubular combustion member 4, the inner portions of the parts 6 of the end walls 5 extending over and above the tubular combustion member 4 and holding it down on the sockets 2. The lower portions of the wall parts 6 are received in the sockets 2. The parts 6 of the end walls 5 have outer rectangular flanges 8.

Braces 9 are disposed against the inner surfaces of the parts 6 of the end walls 5, and are connected thereto by bolts I0. It will be understood that any suitable substitute for the bolts may be used. Moreover, the nuts on the bolts may be disposed either inwardly or outwardly, to facilitate taking down the device, there being no patentable novelty in reversing the bolts end for end, Wherever necessary. The braces 9, which are disposed at the upper edges of the parts 6 of the end walls 5, have inner rectangular flanges II, joined together by bolts I2. The braces 9 have outer rectangular flanges ,I 4.

Side walls I5 are provided, and have a downward slope. The side walls I5 are connected by bolts I5 to the outer rectangular flanges 8 of the wall forming parts 6 and to the outer flanges I4 of the braces 5.

Angle brackets I! are provided. The upright arms of the angle brackets I! are disposed outwardly of the side walls I5, and the horizontal flanges of the angle brackets are disposed on top of the beams I, underneath the parts 6 of the end walls 5. The lowermost of the bolts I6 pass through the upright arms of the angle brackets H, the horizontal arms of the angle brackets being connected by bolts I8 to the beams I.

Doors I9 are supplied for the ends of the tubular combustion member 4. One door I9 is provided in its lower edge with an inlet openin 213, the other door being provided in its upper edge with an outlet opening 2|. The doors I9 have hinge knuckles 22, disposed between hinge knuckles 23 on a plate 24 secured to one of the members 6 of the end wall 5. A hinge pin 25 passes removably through the knuckles 22 and 23. Each door I9 has an arm 26, adapted to be engaged by a latch mechanism 21, of any desired sort, mounted on one of the parts 6 of the end walls 5.

The device may include any desired number of intermediate walls 28, constructed like the end walls 5. Owing to the provision of the intermediate transverse walls 28, the structure is divided into bins 29, each of which is adapted to receive a predetermined amount of sand to be heated. The sand, thus, is measured as it is heated. The heated sand about the tubular combustion member, can be shoveled out from between the beams I, beneath the combustion member 4. The bins 29 are emptied successively, and are filled as soon as emptied. The operator works from one end of the structure towards the other, and by the time he returns to the original bin, say the right hand bin in Fig. 2, the sand therein will have become heated.

Referring to Fig. 3, it will be noted that the opening 20 in the corresponding door I9 is at the bottom of the combustion member 4, the opening 2| in the other door being at the top of the combustion member. If the wind hauls, it may be desirable to reverse the draft through the combustion member 4. This can be done by withdrawing the hinge pin 25 in the knuckles 22 and 23, the doors being inverted.

The device may be taken down to any desired extent. By removing the bolts I5, I2, and I8, the side walls and the end walls and the intermediate walls may be removed as two units. Each unit, in its turn, can be resolved to smaller parts by taking out the appropriate bolt. The structure is so made that it can be knocked down into parts of so small size that they can be loaded readily by one man to a truck for transportation.

Having thus described the invention, what is claimed is:

1. A heater of the class described comprising base beams, an open-bottomed receptacle supported on the beams, the beams being spaced to give access to the receptacle, a tubular combustion member opening through the ends of the receptacle, doors for the ends of the combustion member, one door having a bottom air inlet and V tacle, including end walls and intermediate walls, the lower portions of the walls being received in the sockets, and a tubular combustion member extended through the walls, the sockets being convexed to form seats for the combustion member, each of the walls comprising laterally-separable parts, and means for holding said parts together, said parts overhanging the combustion member and having curved inner edges conforming to the cross section of the combustion member.

3. A heater of the class described comprising a receptacle, transverse beams forming a groundengaging support, and on the upper surfaces of which the receptacle is supported, to define a space below the receptacle, the receptacle being open-bottomed, to discharge downwardly into said space, said space being open at its sides, from beamto beam, and throughout its entire height, to permit material to be removed from said space without lifting the material. and a tubular combustion member opening through the ends of the receptacle.
