MACHINE FOR WORKING CLAY, 8w.

SPECIFICATION forming part of Letters Patent N 0. 595,357, dated December 14, 1897.

Application filed October 15, 1896.

To all whom, it flea/y concern:

Be it known that I, GEORGE E. TAYLOR, a citizen of the United. States, residing at Austin, in the county of Mower and State of Minnesota, have invented certain new and useful Improvements in Machines for Working Clay andSeparating Objectionable Matter Therefrom; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for working clay and separating objectionable matter therefrom.

The object is to produce a machine which will thoroughly and effectively work and mix clay and at the same time separate therefrom objectionable matter, such as stones, lime, or the like; furthermore, to produce a machine which will reduce the clay to a uniform temper and size, thereby fitting it to take moisture readily; furthermore, to provide a machine in which the operating mechanism will be so constructed and arranged as effectually to prevent objectionable matter being'caught and held in the machine, thereby obviating danger or derangement or breakage of the parts.

With these objects in View the invention consists in the novel construction and combination of parts of a clay-working machine, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like letters 'of reference indicate corresponding parts, I have illustrated a form of embodiment of my invention, although it is to be understood that other forms of embodiment maybe employed without departing from the spirit of the same, and in the drawings Figure 1 is a view in perspective showing the machine as it appears when set up for use. Fig. 2 is a view in end elevation displaying more particularly the gate through which stones and other refuse matter may be removed from the machine. Fig. 3 is a view in elevation of one of the grate-rings removed from the machine, showing the knife or cutter in operative position with relation thereto. Fig. 4 is a view in end elevation of the Serial No. 609,002. (No model.)

bottom portion of one of the grate-rings. Fig. 5 is a detail view in perspective of one of the knives or cutters.

Referring to the drawings, A designates the cylinder or body of the machine, the same being composed of any number of grate-rings a, arranged at any desired distance apart, the

spaces between these rings when assembled 6o determining the degree of fineness or coarseness of the'clay when worked. These graterings comprise each a circular body portion a and two Wings or projections a perforated vertically, as at a*, and through these perforations extend bolts a for securing the rings in position upon a supporting-frame B, consisting, essentially, of side pieces I) and legs or supports 12 The grate-rings are the same size in cross-section from the top to a point said heads also serving to prevent the escape of clay from the ends of the machine. Upon this shaft are mounted the knives or cutters E, which are disposed in this instance at about an angle of ninety degrees with relation to each other and are constructed in such manner as to constitute at once cutters, transmitters, and cleaners, as will presently appear. Each cutter is provided with a hub-like portion 6, to be secured to the shaft in any suitable manner, as by a key, and with a pro- 0 jection 6 approximately a rightangle triangle in cross-section and constituting the cutter proper, the same being beveled on one side only to form the transmitting or forcing portion and terminating in the cutting edge,

which curves outward and merges into a shoulder or offset 6 constituting a cleaner which is adapted to work between the rings and keep the opposed faces thereof free from any accumulation of clay, this shoulder also 109 subserving the further function of removing small gravel or stones that may lodge between the rings. The beveled faces of the cutters are disposed toward the discharge end of the machine and by working against the body of clayimpart a longitudinal movement thereto, thereby operating to present the clay progressively to the cutters as it is moved along, resulting in its complete and effective separation and mixing. lVhen the clay has been reduced to the proper degree of fineness, or when it is thoroughly worked, it will pass through the grate-meshes on the lower side of the cylinder, the larger stones and other refuse remaining within the cylinder. After the machine has operated for a certain time a gate F at the discharge end of the cylinder is opened and this refuse is removed. This gate may be of any preferred construction and in this instance comprises a circular plate mounted for movement on the end of the shaft and provided with a semicircular opening through which the refuse from the cylinder may be removed, a handle or lever f being provided for turning the gate to prevent the escape of clay. The rear head C is provided with an opening corresponding to the opening of the gate and registering therewith when the lever is in the position shown in full lines in Fig; 2; but when the lever is moved to the position indicated in dotted lines in the said figure the opening in the is engaged by a pinion g on the drive-shaft G, the latter being provided with a pulley g driven from any suitable source of power.

The operation of the machine is as follows: The clay, as dug from a bank, is fed into the machine through a hopper H and thence into the body of the cylinder, the gate being closed. As soon as the shaft D begins to revolve the cutters commence immediately to break upthe clay, the beveled faces thereof forcing it toward the rear of themachine, so that the clay is thoroughly broken and mixed by the action of the successive knives, the oifset 6 serving to keep the spaces between the rings clear of any obstruction that would hinder the escape of the clay. When discharged from the machine, the clay will befound to be thoroughly and evenly mixed and cleared from all objectionable matter.

Having thus fully described my invention, what I claim as new, and desire'to secure by Letters Patent, is

1. A machine for working clay, comprising a plurality of grate-rin gs, a shaft located within the rings, a plurality of cutters carried by the shaft, each cutter having a portion adapted to work between the said rings and an inclined face for'imparting longitudinal movement to the clay, a hopper at one end-0f the machine, and a discharge-gate at the opposite end, substantially as described.

2. A machine for working clay, comprising aplurality of grate-rill gs, a shaft located within the rings, a plurality of cutters carried by the shaft, each cutter having its outer end adapted to work between the grate-rings and its intermediate portion beveled on one side, a hopper at one end of the machine, and a discharge-gate at the'opposite end, substantially as described.

3. A machine for Working clay, comprising a plurality of grate-rings rigidly supported upon a frame, a head arranged at each end of the frame and closing the end grate-rings, a shaft j ournaled' in the heads and located within the grate-rin gs, knives or cutters carried by the shaft and having their outer ends adapted to work between the grate-rings and their intermediate'portions to constitute, at once,cutters and transmitters, a hopper at one end of the machine, and a discharge-gate at the opposite end, substantially as described.

4. A machine for working clay, comprising a plurality of grate-rings supported upon a suitable frame and having their lower portions reduced, heads for closing the end graterings, one of said heads being provided with an escape-opening, a shaft journaledin the heads'and' located within the grate-rings, a

plurality of knives or cutters carried by the shaft, and having their extremities adapted to work between the grate-rings and their in'- termediate-portions formed to constitutecutters and transmitters, a hopper at one end of the machine, and a gateloosely mounted on the shaft, and having an opening adapted,

when in one position; to register'with the openingin the head at the'dischargeend'of the machine, and,when moved to another position, to close'th'e said opening, substantially as described.

5; As a new article of manufacture, a cutter for clay-working machines, comprising a' hub and a'blade, the outer extremity of the-latter being substantially rectangular in crosssection, and the intermediate portion approximately' a right-angle triangle in cross-sectionthat is to say, having one flat'face and i one beveled face, substantially as described. In testimony whereof I aflix my signature in presence of two witnesses.
