IMPROVEMENT IN EVAPORATlNG-PANS.
Specification forming part of Letters Patent No. 144,158, dated October 28, 1873; application filed October 14, 1873.
To all whom it may concern:
Be it known that I, GEORGE W. Sronnn, of Philadelphia, in the county of Philadelphia, and in the State of Pennsylvania, have invented certain new and useful Improvements in Evaporating-Pans; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings making a part of this specification, in which- Figure 1 is a plan view of the upper side of a portion of my improved pan. Fig. 2 is a side elevation of the same; and Figs. 3 and at are vertical sections of the same upon lines passing respectively through the connectingpipes, and through the clamping angleplates Letters of like name and kind refer to like parts in each of the figures.
My invention relates to the construction of pans or vats for evaporating liquids by the application of heat, and it consists, principally, in the means employed for combining the wooden sides and metal bottom, substantially as and for the purpose hereinafter specified. It consists, further, in the means employed for securing together the abutting ends of the wooden side pieces, substantially as and for the purpose hereinafter shown. It consists, finally, in the pan as a whole, when its several parts are constructed and combined to operate in the manner and for the purpose substantially as is hereinafter shown and described.
In the annexed drawings, A and A represent cast-iron sections of a pan-bottom, each of which is provided, within its lower side, with a recess, a,that extends laterally outward to a point near each edge of the section, and is inclosed beneath by means of a sheet-metal plate,-B, that is riveted or otherwise secured upon the lower side of said section immediately outside of said recess, which latter is thus formed into a chamber. Inunediatcly over the chamber a the cast-metal plate A is corrugated so as to increase its surface, and upon the lower side of each depression provided a number of bosses, a, which extend downward to the plate B, and receive each a screw or rivet, I), that passes upward through the latter, and connects said parts together. The especial office performed by these bosses is to furnish bearingpoints against which to rivet the bottom plate,
and enable the latter to be secured in place without obstructing communication between the grooves formed by the corrugations. The sections thus formed have their contiguous edges nicely fitted to each other, and are secured together by means of angle-plates G,
which are attached at suitable points upon the lower side of each near the said abutting edges, and within their downward-extendin g arms are providedwith horizontal openings 0, that coincide with similar openings in an angle-plate attached to the opposite section, and permit bolts D to be passed through the same. By screwing inward upon the nut of each bolt the angle-plates will be drawn toward each other, and the edges of the sections pressed firmly together. If desired, the joints between said sections may be packed or calked; but as they only require to be made water-tight, it is believed that the contiguous edges can be planed sufficiently true to enable said joint to be made without packin Upon the upper side, and just within the outer edge, of the bottom plate A is provided a groove, a, which at its bottom is horizontal, while its outer side incline upward and outward at an angle of about thirty degrees, said groove being continuous, and extending around the entire edge of the said bottom plate. \Vithin the groove, at each side thus formed, is placed the edge of a wooden side piece, 1* w]iieh corresponds to and fills said groove, and, extending upward to a suitable height, has its ends mitered to or upon the contiguous ends of the adjacent side pieces, as shown, said abutting ends being seemed together by means of an angleplate, ll, attached to each, through which plates a bolt, G, is passed, the projecting arms of said an gle- 'ilates being parallel to each other and to the miter line, while the line of said bolt is at a right angle thereto, so that the strain of the latter draws the said mitered ends squarely together. A water-tight joint can easily be made by closely fitting the ends of the side pieces; but, as a further security, a wooden pin, 0, may be driven into an opening formed at the center of the miter joint. The sides Eare connected to or with the metal bottomby means of bolts H, which at suitable points pass downward through the former at their transverse centers, and have their threaded ends contained with- PATENT Crrron. I
in corresponding thrcznlcd openings provided within the metal at the bottom of the groove 4. A metal cap, 1', is placed beneath the head of each bolt H, and, extending transversely across the upper edge of the side piece, has its ends turned downward against the inner and outer faces of the same.
. If desired, the outer arm of the cap or clamp may be extended downward nearly to the bottom plate, and then outward at a right angle to the line of the side piece, and the bolt H passed through said angular projection, and into or through a lug, a, formed upon the outer edge of said bottom plate, such arrangement of parts being merely a modification. of that before described.
In use, the bottoms of the vats or pans are constructed from nine seetionsthree in each direction-each of which is four feet. wide and twelve feet long, so that the area of the inner side of the pan is about twelve by thirty-six feet.
WV hen water is employed, for heating the contents of the pan, the spaces or chambers a are connected lengthwise of the vat by means of siphon-shaped pipes K, the ends of which are attached to or upon lower sides and near the abutting ends of the sections, water being admitted to the front end of the forward section of each row, and taken from the rear end of the rear section of the same; but'in the event of using steam for heatin purposes the connectingpipes will be omitted, a steam -pipe will extend along each side of said vat, and connections will be made between the same and the forward end of each chamber. A second pipe will connect with the rear ends of said chambers, so as to permit the condensed steam to escape therefrom. Between the ends of the corrugations of the sections is a plane strip, which has the same horizontal plane as the bottoms of the'grooves between said corrugations, while at each end of the pan is provided a channel, A, that extends from side to side, and has its bottom somewhat below the level of said grooves. An inlet and an outlet pipe, L and M, respectively, caused to enter the vat at the longitudinal centers of the channels A, at the ends of the vat, completes the same, the operation of which will be sufliciently plain from the foregoing description.
The advantages obtained by my construction are as follows: First, by making the bottom in sections, a pan having any desired size can be produced at as small a cost in proportion to its capacity as can one having the size of one section only. Second, my construction of the bottom rende s practicable the production of a cast-metal-bottomed pan having any desired capacity, while, as heretofore constructed, a very limited capacity only was attainable, wrought metal was requisite, and
the expense was materially greater in proportion to capacity than in case of my pan. Third, my construction enables me to construct any size of pan at a point where all necessary machinery and conveniences can be had, and afterward easily and cheaply transport to and set up said pan in position at the place where it is to be used, while in case of pans having their bottoms formed in one piece the diffi eulties of transportation will prohibit the construction and use of those above a certain comparatively small size. Fourth, the construction of the side pieces and their combination with the bottom produces a strong, durable, and cheap pan, which can easily and quickly be taken apart or put together, either for transportation or repairs.
Having thus fully set forth the nature and merits of my ii'ivention, what I claim as new 1. The wooden sides E, fitted into the groove a{ of the bottom A, and secured to or Within said groove by means of the bolts H and caps I, substantially as and for the purpose specified.
2. In combination with the mitered ends of the side pieces E, the angleplates F and bolts Gr, substantially as and for. the purpose shown.
The liereinbefore-described evaporating pan, having a sectional hollow metal bottom and wooden sides, said parts constructed and combined in the manner and for the purpose substantially as specified.
In testimony that I claim the foregoing I have hereunto set my hand this 13th day of October, 3.
