ALFRED A. ANDERSON, OF GAL ESBURG, ILLINOIS. Letters Patent No. 72,440, dated December 24, 1867.

IMPROVED MORTAR-MILL,

To ALL WHOM IT MAY coNcnnN.

Be it known that I, ALFRED A. Annnnsou, of Galesb'urg, in the county of Knox, and State of Illinois, have invented certain new and useful Improvements in Machines for Mixing- Mortar; and I do hereby declare that thefollow'ing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the lettersof reference marked thereon, like letters indieating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, I will proceed to describe My invention-consists of a machine for grinding and mixing mortar for use in building walls, plastering buildings, &c.,- as hereinafter described. i i

Figure 1 represents a side elevation, with a portion of ,the case-broken away to exhibit the internal arrangement.

Figure 2 is a rear-end view and Figures 3 and 4 views 'of different forms of the grinding and mixing-rolls.

' In preparing mortar. for use, either in laying up walls or for plastering the walls and ceilings of buildings,

it is customary to incorporate or. mix the ingredients by hand, which is a. slow and laborious process. The

object of my present invention is to provide a machine for doing this work, whereby the labor may be lessened and the operation greatly expedited. I

To accomplish this object, Iprovide a cylindrical metallic case, A, more or less conical, as represented in fig. 1, and mount it upon a. suitable frame, D,'which'should be provided with axles for mounting the machine on wheels, for'conveying it from place to p1ace,.as required, for use. Upon this case, near itsrcar or larger end, is secured a hopper, B, for receiving'the materials to be mixed, there-being an opening at the bottom of .this hopper, through into the case A, to permit the materialto pass to the grinding and mixing-apparatus located within. 7

The grinding and mixing-apparatus consistsof a. spirally-grooved or fluted roller, 0, of such a size as nearly to fill the interior of the caseA, it being made conical to correspond therewith, and mounted on jour nals at each end,so' as to revolve freely in the case. Upon thecnd of the journal, at the rear end of the machine, ;is secured a geanwheel, 6, which gears into a pinion, e, mounted in the fram'e by its side; and by means of [a handle or crank, h,-motion is imparted to the pinion e, and thereby to thecylinder G, which is thus made tot-evolve in such a direction as that the grooves or flanges, while thoroughly grinding and mixing the material fed 'inatthe hopper, shallat the same time work the'same forward to the front or smaller end of the cylinder, where it passes out through an opening in the lower side of the case, as represented in fig. 1.

' Insteadof-thespirally grooved roller 0, other forms may be used, and for some kinds of mortar may be preferablef In fig, 3 is represented a modification of the grinding-cylinder, which consists of a plain conical roller, I, having a series of radial flanges projecting from its surface and arranged spirally thereon, as shown; or it may consist of a central shaft having heads E F secured at its opposite ends, with a series of plain, grooved, or spiral ,rolls, as represented by i l t, fig. 4, secured thereto in such a manner as to revolve on their journals in said heads E and F; these varion's 'forms being used as may be preferred.

In order to permit of' the ready removal and changing of the different styles of grinding-cylinders, the rear end, A, of thecase A is made removable, it being held in place by means of pivoted latches or bars 1;, on opposite sides of the case, which hook over projecting lugs on the end piece A. 7

It is of course obvious'that the machine may be operated by animal or steam-power instead of hand-power, and that it may be made of any required size, to adapt it for use on a large or small scale, as required.

Having thus'described my invention, what I claim, is-

A mortar-mixing machine, consisting of the case A, provided with a hopper, B, detachable end piece A, and the gear-wheels b 0, arranged to operate a grinding or mixing-cylinderplaced within the hopper, the whole constructed and mountedon a carriage, substantially as described.
