EVAPORATING-PAN.

SPECIFICATION forming part of Letters Patent No. 248,506, dated October 18, 1881.

i Application led August 16, 1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. RoAoH, of Fulton Station, in the county of Fulton and State of Kentucky, have invented a new and usefullmprovementinEvaporating-Pans; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specication, in which- Figure. l is a plan view of my improved evaporating-pan. Fig. 2 is a vertical longitudinal section on line cc cc, Fig. l. Fig. 3 is a vertical longitudinal section on line yy, Fig. l; and Fig. 4L is a vertical transverse section on line z z, Fig. l.

My invention relates to improvements in pans for evaporating saccharine Iluids; and it consists, rst, in the peculiar construction and arrangement of gutters and aperforated plate, whereby the scum is automatically conducted out of the pan, thus making the pan, when in operation, a self-skimming one.

My invention further consists in certain details of construction hereinafter more fully set forth.

In the accompanying drawings, A represen ts my improved evaporating-pan, of any desired length, and adapted to be inserted -in an arch over a nre.

a and b represent two parallel transverse partitions, extending across the pan near its rear end, and forming two compartments, c d, of the same Width. The width of the compartments c d depends upon the length of the pan A, and the width of these compartments is usually about one and threesevenths inch for every foot in length of the evaporating-pan, although these dimensions may be varied as desired. The compartment c is provided with an opening, c, in one end, nearits bottom, for the passage of the saccharine fluid out of the pan, and an opening, f, is made in one end of the partition a,near its bottom, governed by a sliding gate or valve, g, whereby the ow of the saccharine fluid into the compartment c can be regulated as desired.

h represents a baffle-plate, arranged in the compartment d, opposite the opening f and sliding gate g, to impart a more tortuous iiow to the sacch arine fluid, as hereinafter described. The partition b is provided with the openings ij near its bottom and at each end, which lead into the longitudinal compartments k 7c', arranged on opposite sides of the pan. The compartments k Z m la are formed by the parallel longitudinal partitions n 0 p, extending from the frontend ofthe pan to the transverse partition b. q and r represent openings at the bottoms of the partitions n and p, near the front end ofthe pan, thus forming communications between the compartments 7c and l and m and 7c. The partitions a and pare each provided with an offset or gutter, s, near its upper edge. These gutters s are slightly inclined from the front toward the rear of the pan, so as to convey the scum which rises to the surface ofthe boiling iiuid toward the rear of the pan, and thence over the surface of a perforated plate, t, slightly inclined laterally, and connecting the inner ends of the gutters, and leading to an opening, u, in the side of the pan, whereby the scum is automatically conducted from the surface of the saccharine uid ont of the pan.A

In the passage of the scum over the perforated plate t, in its passage out of the pan, any saccharine uid that may be carried with the scum will pass through the perforations in the plate and fall back into the compartments lm. By this construction the labor of skimming is avoided, the skimming process being automatic.

In practice the sirup or saccharine fluid is introduced into the compartments lm at their inner ends, and passes, in the direction of the arrows, through the openings q and i', into the compartments k lo', thence through the openings j into the compartment d, and thence through the opening j', governed by the sliding gate g, into the compartment c, and thence through the opening c out of the pan, the sac charine fluid being thus forced to take a very circuitous route from its entrance into the pan until its departure therefrom.

I claim as my invention- 1. The combination, with the compartments l m, having partitions n p, provided with inclined gutters s, of a plate connecting the inner ends of the gutters, and adapted to automatically carry the scum through an opening in the side of the pan, substantially as described. l

2. The combination, with the compartments IOO lm, having partitions 'n p, provided with iul parallel longitudinal compartments k l m kf, cliued gutters s, of the perforated vplate t, conhaving openings i j q r, gutters s, perforated uectug the inner ends of the glitters, and plate t, and transverse compartmeutscd, Sepaadapted to automatically carry the scuni rated by the partition a, having openingfaud through an opening in the sides of the pan, sliding gate g, substantially as described, and 15 and allow the saeeharine fluid in the scum to for the purpose set forth.

fall back into the pan, substantially as de- VILLIAM H. 4ROAGH. scribed. Vitnesses 3. The evaporating-pan herein described, HENRY C. WESSON, consisting of the pau A, provided with the] XV. H. WEAVER.
