SPECIFICATION forming part of Letters' Patent No. 576,859, dated February 9,1897;-VVA l, v,

Application-filed April 1S, 1896. Serial No. 587,328. (No modehl To (di u'mnt it nt/Ly cortcc'u:

Be it known that I, J ULIUs EDWARD Kons- -TER, of New York city, in theeounty and State Vmorees-pe'cially designed for heating or cooling liquids and arranged to'permit of convenientlycleaning the -coil to Aremove sedi ment, circ.

15 The invention consists of a coil comprising grooved sections and a division-platev or partition separating the grooved sections and having an opening for connecting the adjacent ends of the grooves with each other to `zo cause the liquid to rstpass through the groove in one section and then through'the groove in the other section.

. The invention also consists of certain vparts and details and combinations of the same, as 2 5 will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the' accompanying' drawings, forming a part of this specification,

in which similar characters of reference indi- 30 cate corresponding parts in both the figures.

Figure il is a plan view of thel bottoni section with part ofthe divisionplate in place,

and Fig. 2 is a sectional side elevation of the improvement on the line 2 2 of Fig. l.

3 5 The improved coil is provided with two sec-. tions A andB, and a division-plate or partition C, placed between the two sections to separate the same, the sections being connected with each other by suitable bolts D 4o for clamping the division-plate in position between the two seotions.-

In the section A, on the `face next to the division-plate C, is formed a groove A', preferably made spiral, as indicated in Fig. l, the

45 outer end of the groove being connected with an inlet-opening A2, adaptedl to connect with the liquid-supply. The other section B Vis formed on its inner or under face with a similar groove B', and the -inner ends of. the two 5o grooves A B are connected with each other byan. opening C', formed in the division or partition plateC. Theouter end of the groove B' leadsjto an outlet B2, connected with adischarge-pipe.

Now it will be seen that byv the 'arrange- 5 5 y 'ment described the liquid entering the inletV A2 can readily liow through the spiral groove 'Ato the-middle or'center of the said section A, to then pass through the opening C into the inner end of the groove B', and then pass 6o along the same in anoutward direction to --finallypass into the outlet A2 and through the discharge-pipe. IE desired,the liquid can pass ina'reverse direction-that is, first circulate through the section B and then out 6 5' through the'section A.

In'order to clean the coil, the bolts D are removed and the sections taken apart to expose th'e faces of grooves A and B', so that .l said grooves 4can be readily cleaned of sedi- 7o ment and other impurities. The parti-tionplate C can be readily washed to remove any impurities adheringrthereto. It will be seen that this coil is very simple in construction,

can be, readily cleaned, and subjected to a 5.

high or. low temperature, sov asto'heat or cool the liquid flowing through thecoil, It is further evident that three, four,;or'mor e sections may be connected with each otherywith intervenin g platesto circulate the liquid through 8o y a desired number of connected grooves.

Having thus fully described myvinvention,

I claimas new and desire to secure by Letters Patent- 1. A coil, comprising two or more grooved 85 sections, and a division-plate or partition separating said sections and having an ope-ning'forconnecting the adjacent ends of the grooves with each other, and causing the liquid tolirst flow through the groove in one 9o section and then through the groove in the other section, substantially as shown and described.

2. A coi-l, lcomprisingtwo or more grooved sections each formed on its face with a' con 95 tinuous groove leading to an inlet or outlet, and a division-plate or partition between the sections for separating the grooves, said division-plate being formed withv an opening for connecting adjacent ends of the grooves Io'o provided with a transverse aperture leadi g;

from the groove of one section to that of adjoining section, the groove being provided at a distanee'froni said conneming-aperture,

with openings adapted to serve as an inlet and an outlet respectively, as and for the pur zo pose set forth.

5. A coil comprising two or moresections provided with continuous spiral grooves in their opposing faces and openings at the outer endsvofesaid grooves, said openings being 25 'adapted to serve as an inlet and an outletv respectively, and a division-plate or partition located between saidgr'ooved faces of the seel tions and provided with an4 approximately central aperture leading from the inner end 3o.

of the groove in one section to the inner end of the groove in the adjoining section, as and for the purpose set forth.
