EVAPORATO R.
SPECIFICATION forming part of Letters Patent No. 744,867, dated November 24:, 1908. Application filed May 5, 1903. Serial No. 155,738. (No model) T0 on whom it may concern.-
Be it known that I, HENRY J. LYMAN, a citizen of the United States, residing at Corry, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Evaporator-s, of which the following is a specification.
This invention provides means'for quickly reducing sap to any required consistency by driving off the excess of Water by evaporation through the agency of artificial heat.
The invention consists, essentially, of two side pans, til-shaped tubular bars connecting said side pans and forming a fuel-grate, a straight pipe connecting the side pans for return circulation,and deflectors located within the side pans over the ends of the U-shaped tubular bars to prevent overflow of the sap from any cause.
The invention also consists of the novel structural features, which hereinafter will be more particularly set forth and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of an evaporator embodying the invention. Fig.2 is a transverse section of the end portion having the fuel-grate.
Corresponding and like parts are referred to in the following description and indicated in both views of the drawings by the same reference characters.
The invention consists, essentially, of side pans 1 and 2, U-shaped tubular bars 3, deflectors 4, and return-pipe 5. These parts, arranged substantially as shown, are adapted to be applied to an evaporator of any structural type, make, or design.
The U-shaped tubular bars 3 are disposed in parallel relation and are connected at their ends with the respective pans 1 and 2 and constitute a fuel-grate for supporting the fire, by means of which the evaporating process is efiected. The side pans 1 and 2 are oblong and are placed so as to extend over the fuelgrate, the bars of which connect with their bottom adjacent to the outer side, so as to leave a maximum amount of the pans overhanging the fire to receive the full benefit of the heat rising therefrom. The deflectors 4: are plates curved upward intermediate of their longitudinal edges and arranged within pan 2 by way of pipe 5.
the lower portion of pans 1 and 2, so as to extend over the extremities of the tubular bars 3 and prevent spurting upward of the sap during the boiling and evaporating process in the event of a sudden accumulation of steam at one or more points or from other cause. The tubular bars 3 in addition to forming a fuel-grate serve to establish circulation between pans 1 and 2 and to provide an extended surface for action of the heat in boiling the sap or syrup. The return-pipe 5 connects pans l and 2 near their upper forward ends and may be of any diameter to insure circulation which is necessary in the treating of the sap to increase its density and consistency.
,A shallow pan 6 is interposed between side pans 1 and 2 and extends directly above the fuel-grate and receives the sap from one of the side pans after it has acquired the proper density. In the rear of evaporating-pan 6 is located pan 7, same extending over the hotair space 8, located in the rear of the fuel grate and constituting, in effect, the combustion-chamber. Smoke-pipe 9 communicates with smoke-space 10 in the rear of hot-air space of combustion-chamber 8. Pans 6 and 7 may be of any construction, such as commonly provided in appliances of the character relating to the present invention.
In the operation of the invention'sap from a tank or other source of supplyis run into one of the side tanks, as 1, and fills the tubular fuel-bars 3 and flows into pan 2. The heat derived from the fire built upon the grate causes the sap to boil and to rise into pan 2, the sap being returned to pan 1. from After the sap has acquired the proper consistency or densityit is discharged from pan 2 into pan 6 through outlet 11, and from pan 6 the sap overflows into pan 7, from which it is removed in any determinate way to be filled into cans or other receptacles for market.
While it is preferred to have the tubular fuel-bars 3 connect with the side pans, as shown, yet they may communicate with the pans at any point below the level of the sap. The cool sap entering pan 1 from tank 12 gravitates into pipes 3 and becoming heated rises into pan 2 and passes therefrom into pan 6 through outlet 11, maintaining a prac ICO and a return-pipe connecting said side pans and extending over the fuel-space, substantially as set forth.
2. In an evaporator,the combination of side pans, tubular bars connecting said pans, and deflectors arranged within the pans above the extremities of the tubular bars, substantially as specified.
3. In an evaporator, oblong side pans, U- shaped tubular bars connected with the bottom of the pans near their outer sides, de-
flectors within the pans above the ends of the tubular bars, and a return-pipe connecting said side pans, substantially as described.
4. In an evaporator, the combination of oblong side pans located above the fuel-grate and overhanging same, tubular bars of approximately U form connected at their ends with the bottom of the side pans near their outer sides and constituting fuel-supports, a return-pipe connecting the side pans, an evaporating-pan located above the fuel-grate and between said side pans, and an evaporatingpan in the rear of the fuel-grate and the series of pans located above the said fuel-grate, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
