Application filed August 24, 1904. Serial No. 221,979.

To all whmn it may concern:

Be it known that I, NEWTON GILBERT Knlerrr, a citizen of the United States, and a resident of Crestline, in the county of Crawford and State of Ohio, have invented a new and Improved Soap-Machine, of which the following is a full, clear, and exact description.

My invention relates to machines for effecting saponification, and has for its principal objects the provision of a convenient arrangement of gearing for driving the rotatable ele ments and means for introducing material during the operation of the machine.

It consists in the various features and combinations hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indie cate corresponding parts in all the figures.

Figure 1 is a side elevation of one embodiment of my invention, parts being broken away; and Figs. 2 and 3 are transverse sections therethrough on the lines 2 2 and 3 3, respectively, of Fig. 1.

V designates a vessel which is so arranged that it may be closed during operation and preferably consists of opposite heads 10 10,

between which extend separated cylindrical walls 11 11, conveniently spaced at their ends by rings 11 to form a circumferential cham ber. Opening into the chamber at its top is shown a pipe 13, in which is a valve 14:, and from the lower side of the chamber leads a pipe 15, containing a valve 16. These pipes permit the introduction of steam to the chamber and its circulation therethrough, this being controlled by manipulation of the valves. The vessel may be supported upon any suitable number of standards 16.

Delivering at the top of the vessel near its center is a main feed-pipe 17, in which is a valve 18, a suitable enlargement or funnel 19 being also provided to facilitate the introduction of the material which is to be operated upon. Through the head 10 of the vessel extends a secondary feed-pipe 20, which after extending horizontally for a short distance interior of the vessel. The pipe 23 contains a valve 24; Leading through the head of the vessel at its lower edge and below the pipe 20 is a discharge-pipe 25, containing a valve 26, and at the opposite end of the vessel, it being shown as passing through the head at a point above the pipe 25, is a test discharge-pipe 27, in which is a valve 28. An air-cock 28? is also provided.

Through the vessel extends a shaft 29, journaled at one end in a recess 30 in the head 10 and passing through a stuffing-box 31 in the opposite head. Upon this shaft is fixed a series of mixing-blades 32, which are inclined to enable them to move material through the vessel and thoroughly commingleit. Upon the shaft outside the stuffing-box is a pulley 33, through which rotation may be imparted at the desired speed. About the shaft rotates a reel which is shown as supported by spiders 34:, situated near the opposite ends, the arms of these spiders being connected by buckets 35, preferably of a semicylindrical or curved form. These buckets outside the spiders are attached to end plates 36 and 37 the latter of which is in the form of an annulus. Fast upon the shaft is a gear 38, situated within the plate 37 and having meshing with it a pinion 39, provided at one side with a journal 40, mounted in a recess 41 in the head 10*. pinion also cooperates with an internal gear 42, extending about the inner periphery of the plate 37.

In using the machine the materials to be operated upon, as fatty matter and an aqueous alkaline solution, are introduced into the vessel through the main feed-pipe in the proper amounts. Steam is then supplied to the outer chamber of the vessel by the pipe 13 and allowed to flow therethrough and out through the pipe 15. The various valves controlling the pipes opening into the. vessel arethen closed and the shaft rotated at the proper speed. This will move the contents through the vessel and thoroughly mix them, and at the same time the buckets will carry down portions of the vapor formed within the vessel an additional amount of some of the ingredients is needed, the valve 22 in the pipe 20 This is opened, valves 22 and 24 being closed, and the material introduced through the funnel. The valve 22 is now closed and 22 and 24 opened. This not only establishes communication with the interior of the vessel, but also allows the pressure therein to act through the pipe 23 and equalize with that in the chamber. This allows the contents of said chamber to flow by gravity into the vessel and be there mixed with the original charge. This proceeds until the test shows that the operation is completed, when the valve 26 is opened and the contents of the vessel discharged.

It will be seen that by placing the gearing between the shaft and the reel within the vessel one end of the machine is left entirely free for the inspection of the progress of saponification and greatly increases the ease with which the operator may move about the apparatus, this resulting in economy of timea decidedly important consideration, since unloading requires prompt action.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent 1. A soap-making machine, comprising a jacketed vessel having a main feed-pipe and an auxiliary feed pipe, a rotatable shaft mounted in the heads of the vessel, mixingblades on the shaft, spiders loosely mounted on the shaft near the ends thereof, plates loosely mounted on the shaft between the spiders and the heads of the vessel, one of the plates being in the form of a ring and having internal gear-teeth, semicylindrical buckets secured to the spiders and to the said plates, a gear-wheel on the shaft within the ring-like plate, and a pinion mounted in the head of the vessel adjacent to which the ringlike plate is located and meshing with the gear of the said plate and the gear-Wheel, substantially as described.

2. In a soap-making machine, a vessel, a rotatable shaft mounted in the heads of the vessel, mixing-blades secured to the shaft, spiders loosely mounted on the shaft near the ends thereof, plates loosely mounted on the shaft between the spiders and the heads of the vessel, one of the plates being in the form of a ring and having internal gear-teeth, curved buckets secured to the spiders and plates, a gear-wheel on the shaft within the ring-like plate, and a pinion mounted in the head of the vessel and meshing with the gear-wheel and the internal gear of the said plate, substantially as described.

3. In a soap-making machine a vessel, a rotatable shaft mounted in the heads of the vessel, mixing-blades secured to the shaft, buckets rotatable about the shaft, an internal gear carried by the buckets adjacent to the inner face of one head of the vessel, a gear-Wheel on one end of the shaft, and a pinion on the inner face of the head of the vessel and meshing with the gear-wheel and the internal gear carried by the buckets, substantially as described,

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
