AIPPARATUS FOR COOLING OR WARMING WATER, AIR, OR GAS.
Specification of Letters Patent.
Patented Feb. 20, 1912.
Original application filed May 27, 1911, Serial No. 629,783. Divided and this application filed August 24,
To all whom it may concern:
Be it known that I, HAMMERSLEY HEE- NAN, a British subject, residing at Manchester, county of Lancaster, England, have invented certain new and useful Improvements in Apparatus for Cooling or \Varming Water, Air, or Gas, of which the following is a specification.
The invention relates to apparatus for cooling or warming water, or for cooling, warming or humidifying air, (or which may be applied for other similar purposes), in which a laminated drum rotates with its lower portion immersed in a trough of water or other liquid, and air or other gas is blown or drawn through the upper portion of the drum, the convolutions or windings being covered with a film of water taken up by the rotation of the drum through the water in the tank. Such drums are made of a number of convolutions of sheet metal wound spirally around a central hub or a pair of disks. Various methods have been proposed of spacing and securing the convolutions of the drum at regular intervals apart, such as by passing bolts or studs down through them, inserting washers of the desired thickness between the plates and tightening the bolts thereon. Difiiculty and expense attend this method of construction and also others that have been proposed.
This invention consists essentially in winding with the sheet metal a flexible removable spacing band at one or both edges to obtain regular spacing of the convolutions of sheet metal, subsequently drilling holes through the metal plates and screwing into each hole a screw the threads of which will engage the edges of the holes in the plates through which they pass and secure and hold the plates rigidly, and, finally, when the plates are thus secured, removing the flexible spacing bands and also, in addition thereto, building up the drum in a number of sections in similar manner, with a foundation ring bet-ween each section.
This application is a division of application Serial No. 629.788, filed May 27, 1911.
The invention will be fully described with reference to the accompanying drawings.
Figure 1. is a side elevation of the apparatus partly in section. Fig. 2. is a transverse sectional elevation. Fig. 3. is a perspective elevation of the spirally convoluted drum, showing the method of winding. Fig. 4 is an enlarged detail section longitudinally of the drum. Fig. 5. is an enlarged detail section transversely of the drum. Fig. 6. is an enlarged detail longitudinal section of a modification. Fig. 7. is an enlarged detail transverse section transversely of the modification shown in Fig. 6.
The drum is built up upon a hub comprising center disks A mounted on a shaft B, with spiral convolutions C of sheet metal wound around them in the usual way.
In winding the spiral convolutions C .of sheet metal, two flexible spacing bands D D of rope or other material are wound up with the sheet metal, the band D at one edge of the drum and the band D at the other edge. The ropes D and D are thus wound tightly up with the sheet metal and the convolutions C accurately and evenly spaced. After the drum has been so built up, (see Fig. 3) holes 0 are drilled at intervals around both edges but inside the ropes D D through the convolutions of the sheets C at suitable intervals, such holes extending through all the convolutions and into the disks A. Into each hole a screw E of suitable pitch is screwed, the threads of the screw engaging with the edges of the holes in each layer or convolution as it passes therethrough. The screws thus secure the convolutions C rigidly and firmly at the desired distance apart without the insertion of washers, distance pieces or other spacing devices. For larger drums, additional screws E may be inserted at or near the center to give additional rigidity thereto.
In the modification shown in Figs. 6 and 7 for large sized drums, the drums may be built up in two or more concentric sections with foundation rings F therebetween, around which rings the convolutions of the second section are wound in the manner hereinbefore described. The foundation rings F receive the ends of the screws E This construction avoids the use of long screws and obviates the difficulty of drilling deep holes through the convolutions C of the lates. p When the drums are built up and all the screws inserted to secure the plates, the flexible spacing bands or ropes are removed or pulled out from the edges of the drum, as their only function is to assist in the building up of the drum and the spacing of the convolutions at the desired distances apart.
What I claim as my invention and desire to protect by Letters Patent is 1. In an apparatus of the class specified, a drum comprising a central hub, a spirally wound sheet of metal mounted thereon, the convolutions of said sheet being provided with holes drilled radially therethrough, and the hub with holes alining with the firstnamed holes, and screws passed through the first-named holes and having their inner ends engaged in the second-named holes, the threads on said screws engaging the edges of said first-named holes, to space said convolutions evenly and hold the same in position.
2. In an apparatus of the class specified, a drum comprising a central hub, a spirally wound sheet of metal mounted thereon, the convolutions of said sheet being provided with holes drilled radially therethrough, a
wound sheet of metal mounted on said ring and provided with holes drilled radially through its convolutions, and inner and outer sets of screws passed through the holes in the firstand second-named convolutions, respectively, and having their inner ends secured, respectively, to said hub and said ring, the threads on said screws engaging the edges of said holes to space said convolutions evenly and hold the same in position.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
HAMMERSLEY HEENAN.
