Specification of Letters Patent.

Application filed April 21,1917. Serial no. 163,596.-

-To all whom it may concern in the county of Mobile and Stateo f A.la'

bama, have invented certain new and use ful Improvements'in Syrup-Evaporators, of which the following is a specification.

My present invention has to do with syrup evaporators. It consists in the peculiar construction, novel combination and adaptation and relative arrangement of parts, as hereinafter described and claimed, wherebythe evaporator is provided with a solid, durable and liquid-tight bottom wall, and the transverse partition walls are fixedly attached to said bottom wall and strongly maintained in position without the employment of solder or any other element liable to be affected by fire or heat.

In the accompanying drawings which are hereby made a part hereof:

Figure l is a longitudinal vertical section illustrating the evaporator constituting the best practical embodiment of my invention that I have as yet devised.

Fig. 2 is a plan view of the same.

Fig. 3 is a. perspective, on an enlarged scale, showing the relative arrangement of the bottom wall and one partition wall precedent to the application of pressure to clamp the engaged parts of said walls and fix the same with respect to each other.

Fig. 4 is an enlarged detail section showing the bottom wall and one partition wall as they appear subsequently to the application of pressure and the fixing of the partition wall to the bottom wall.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

As shown in Figs. 1 and 2 ,my novel evaporator comprises, among other parts, two upright wooden side walls 1 and 2. These side walls 1 and 2 are arranged in parallel relation, and the wall 1 is provided,.adjacent to one of its ends, with a transverse outlet aperture 3 for the discharge of syrup from the evaporator.

Embedded along its side edges in the opposed side walls 1 and 2 is the sheet metal bottom wall 4, and carried by the said bottom wall 4 and each embedded at one end in one wooden side wall are the comparatively high transverse partition walls 5 and the low or shallow transverse partition walls 6. These walls 5 and 6 are alternately secured to opposite side walls, each wall 5 and 6 extending from one side wall and having its free end spaced from the other side wall in order to causethe syrup to, take a tortu one course in passing from the right-hand end of the evaporator toward the discharge outletbefore'referred to, as indicated by the arrows in "F ig.' 2. Aside from difi'erences in height the transverse partition walls 5' and 6 are identical in construction and are similarly fixed withrespect to the bottom wall 4, and therefore a detailed description of the wall 5 and the adjacent portion of the wall 4 shown in Figs. 3 and 4 will suffice to impart a definite understanding of all.

For the reception of the said wall 5, the bottom wall 4 is provided with the opposite folds 7 and the throat 8 between the folds. The wall 5 is formed of a sheet of metal bent on itself to constitute an upstanding portion, and the said sheet of metal is provided at the base of the upstanding portions with flanges 9. These flanges 9 are sheathed, preferably by endwise movement of the wall 5, in the folds 7 and the base of the upstandportion is disposed in the throat 8. The opposed portions of the folds 7 and the flanges 9 are then subjected to pressure to tightly clamp the flanges between the folds whereupon the partition wall will be fixed in and to the bottom wall and a liquid tight joint will be provided between thetwo, and this without the employment of solder or any other extraneous means.

It will be observed in this connection that the upstanding portion of the wall 5 is strongly clamped and held between the upper opposed bights of the folds 7, and the said wall 5 is effectually held at both sides thereof against movement in the direction of its thickness; also, that the sheathing capacity of the folds 7 permits of the wall 5 being expeditiously and easily positioned, relative to the bottom wall before the opposed portions of the folds 7 and flanges 9 are subjected to pressure as described.

In assembling the parts of my novel evaporator, the end portionsof the bottom wall 4 are bent upwardly to form end walls 10, the upper edges of which are beaded as in: dicated by 11, and the side edges of the bottom wall, throughout the length thereof are tightly seated in grooves provided in the in,- ner sides of the side walls, while one end of Patented an. 1, 1918.

each transverse Wall is tightly seated in other and thisgalso contributes-materially to the simplicity, inexpensiveness and durability of the evaporator.

Having described my invention, What I claim and desire to secure by Letters Patent is: V v e V In an evaporator, the combination of a sheet-metal bottom' all having at intervals of its length pairs of opposite folds and a throat between the folds of each pair, and transversepartition Walls carried by the bottom Wall, each of said partition alls being formed of a single piece of sheet-metal foldedupon itself to form an upstanding po tio and eac ha ng ppos tely a hi gi and'the base flanges of the partition Walls beingclamped together, Whereby'the up-g standlng portions of the partition Walls are strongly clamped and held between the upper opposed bightsof the bottom Wall folds and the partition Walls are held at both sides thereof against. movement in the direction of the lengthofthe bottom Wall. V

In testimony whereof I affix my signaturein presence of tWo Witnesses. p
