all "111. out it may concern. Ba known that l, H. Scnnonrnn, a Ul-blZQll of the United States, and resident Chicago, county of Cook, and State of .5 Illinois, have nvented certain new and useful improvements in Candy-Making Machines, of which the following is a specifin, which are illustrated in the drawings, forming a part there n.

e invention. relates to apparatus for cooking and mixing such materials as candy the like, and. more particularly to such apparatus wherein the heat for cooking the material is derived from a gas furnace.

The object of the invention is to provide cand}-' making apparatus which shall be of improved construction and eilicient in oper ntion. is eLreinplified in the strucreinsater described and which d in the accompanylng drawe u is a side elevation of a candy machine e1 ibodving the features of provided by the invention. s. u are detail plan sectional views o the lines 3-3, respece apparatus are preferably 'table standard. In Figs wings, such a standard. in, ii). it rises from. a floor plate, floor plate also serves for supportfor receiving a furnace referably the elevation at held by the furnace, is, is ado ustable.

po 'l of a pair of telescoping ac pted be held in relad position by a set screw, 17. "(as burner of the furnace, is, burner is conveniently y a flexible pipe,l9,'and pipe, 2i, which leads from a permit of the vertical le adj o the furnace, l lfl/ilii pipe, 21, is shown as having a flexible section, 22.

a blower fan, Q0, is shown as being hung un-r r side of a bracket, 23, which standard, 12,.adiacent its 2%, mounted on the o :cket, 23, serves for 20, as through. a belt, =nt- As shown, the

ed upon the motor and the other upon the blower.

A kettle is used for containing the batch of material to be treated. In Figs. 1 and 2 of the drawings this kettle is shown at 28. It is normally supported directly over the furnace,'1 l, the vertical adjustment of the urnace serving to accommodate kettles of different depth. Most desirably the means for supporting the kettle is of such construction thatit may be lifted from the furnace as when the cooking of the batch of material has been completed or. when the cooking is found to be proceeding too rapidly. As shown, the kettle, 28, has handles, 29 and 30,- at its opposite sides and these handles rest upon the arms 31 and 32, re spectively, of a bifurated bracket, The

bracket, 33, is slidingly mounted upon the 1 standard 12. To this end the bracket shown as being provided with a beaiing which slidingly incloses an intermed part, as 35, of the standard. reforably shoulders as 36 and 37 are provided for limiting the slidingmoveinent of the bracket, 33, in each direction, as by making the part 35 of the standard of reduced diameter.

A stirrer shaft, 38, extends down 'ardly into the kettle, 28, and preferably has a dash er, 39, fixed upon its lower end. For supporting the stirrer shaft, 38, in an up right position, it is journaled in a bracket arm, 40, and in abearing, 11, the latter being formed upon the overturned higher end of the, standard, 12. Pileferably the stirrer shaft, 38, rotated by power derived froin the same motor, 24, which is used for driving the blower fan, 20. As shown, this power istransmitted.through a counter shaf, 42, mounted at the top of the standard,- 12, as by being ournaled in upstanding brackets, 4-4: and Speed reducing gears, as all i7, i8 and d9 serve for operatively connecting the counter shaft, 42, with the motor, 24:. The gear, 46, is mounted upon the counter shaft, s2, and is normally connected therewith by a clutch indicated at The gears, 47, 48, are mounted upon an intermediate shaft, 50. T his shaft is convenmay journaled in the bracket, 45, below the counter shaft, 42. The gear, 49, is mount 2d upon the motor, 24c, and meshes with the gear 5;. Beveled gears, 51 and serve for operatwely connecting the counter shaft, 4.2, and s rer shaft, 38. The clutch, i3,

per-

mits the blower fan, 20, to be operated independently of the stirrer shaft, 38, as when a fresh batch of material is to be softened in the kettle, '28, by heat from the furnace, 14, prior to being stirredby the dasher, 39.

To permit the kettle, 2 8, to be lifted from the furnace, 14, Without interrupting the operation of stirringflthe material contained in the kettle, the stirrer shaft, 38, is slidingly mounted in the bearing, 41,- and beveled gear, 52. As shown, the beveled gear, 52, is connected with the stirrer shaft, 38, by a spline, 53. The bracket 40 serves for raising the stirrer shaft, 38, Whenever the kettle, 28, is lifted. To this end the bracket, 40, is formed integral with the bracket, :33. To

provide an additional support for thebracket, 40, said bracket is preferably made in the form of an elbow and a T (Fig. 3) is provided at the angle of the elbow for running in a slideway, 54, formed on the standard, 12. A collar, 56, fixed, upon the stirrer shaft, 38, above the bracket, 4.0, prevents downward movement of the shaft through the bracket and insures the shaft being elevated with the bracket.

Any convenienthand operated mechanism may be employed for'raising and lowering" the bracket, In the form of construction illustrated on sheet 1, a screw. 57, turned by beveled gears, 58, 59, and a lever or crank, 60, is employed. Thescrew, 57, is shown as belng journaled adjacent its opposite ends in bracket lugs, 61, 62, formed upon the 'side of the standard, 12. This. screw passes through and has threaded engagement with a lug, 63, formed on the bracket. 33. The beveled gear, 58, is fixed uponthe higher end of the screw, 57. The beveled gear, 59, and the crank, 60, are preferably rigidly connected and are rotatably mounted upon a stud, (34, mounted upon the side of the standard, 12, adjacent the higher end of the screw.

In the operation of the apparatus. the motor, as 24, is employed for driving the blower fan, 20, but without driving the stirrer shaft, 38, until the batch of material contained in the kettle '28, has been sufficiently softened by the heat from the fnrmice, 14, to permit ofthe movement of the dasher,

On closing the clutch, 43, the

motor, 24:, serves to drive both the blower fan, 20 and the dasher, .39. lVhen the batch of material has been sufiiciently cooked, or

in event the cooking is found to proceed too 33, and kettle 28, in any of its adjusted position s. In this form of. construction, the

kettle may be raised and lowered Without interrupting, the mixing operation.

I claim as my mvent1on- 1. In a candy-making machine, in combination, a kettle, a stirrer shaft extending into the kettle, a driving gear fixed. against 'translatory movement .splined upon the stirrer shaft, :1 wertically movable supporting arm connected to the kettle and to the stirrer shaft and a vertically disposed screw fixed against longitudinal movement and having threaded engagement withthe said supporting screw. a c
