To It. who/lb 1'15 flung (JUN/(16770.
Be it known that I, CYRUS S. WEnT, a citizen of the United States, residing at Kendallville, in the county of Noble and State of Indiana, have invented a new and useful Concrete-Mixer, of which the following is a speciiication.
This invention relates to concrete-mixers.
The object of the invention is in a ready, rapid, thoroughly feasible, and practical manner to effect mixing of sand and cement in such manner as that the resulting product will be of uniform color, thereby obviating the presentation of varicolorcd articles, such as would result where the ingredients are not initially and thoroughly incorporated.
With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a concrete-mixer, as will be hereinafter fully described and claimed.
In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corres onding parts, Figure 1 is a view in vertical ongitudinal section of a concrete-mixer embodying one form of the invention. Fig. 2 is a top plan view. tional view taken on the line 3 3, Fig. 1.
As will be noted by reference to the draw,
ings, the apparatus shown in each of Figs, 1 to 3 is of the vertical type, and in each there is a feature common to b0thnan1ely, that there is a cylinder provided within which is arranged a shaft carrying radially and obliquely disposed inixing-arms which operate to agitate and stir up the sand and cement as it passes through the apparatus and thereby cause a thorough admixture before dischargmg.
Referring to the drawings, 1 {designates a cylinder which may be of any size and is provided with a hopper-shaped bottom 2, terminating ina centrally-disposed discharge mouth In this form of the invention the cylinder is stationaryand is supported upon suitable legs 4, bolted or otherwise secured to the cylinder.
The upper end of the cylinder is closed by a head 5, which in this instance is shown as provided with a circumferential flange 6, through. which and the cylinder pass bolts or rivets 7 for holding the parts properly assembled. At a point near the center of the head and preferably in alinement with each other Fig. 3 is a horizontal scc-' are two fccd- spouts 8 and 9, and supported by the head, as by being riveted thereto a1 10, are two hoppers 11 and 11, which, as shown in Fig. 2, are rectangular in outline. Each of the hoppers has secured to its outer side a bearing 12, in which is journnled a shaft 13, carrying two screw convcyers 14. the flights of one conveyor beii'ig pitched to the right and those of the other to the left. This shaft carries on one end a pulley 15, around which will pass a belt driven from a suitable source of power and upon the other shaft is mounted a fly-wheel 1G. \Vherc the shaft is driven from power, as by means of a belt, the fly-wheel may be omitted but where the shaft is to be driven by hand-power a fly wheel will be employed and the pulley 15 will be removed and be supplemented by a crank.
Mounted centrally and vertically of the cylinder is a shaft 17,- the lower end of which is provided with a cone-socket 18. with which engages a cone-shaped bearing 19, carriedby a grid 20, secured interiorly of the cylinder, as by bolts 21. The cone-bearii'ig forms a part of a bolt 22, which is threaded in a hub or enlargemcl'lt 23 at the center of the grid and has its lower end provided with a head 24, by which it may be adjusted to compensate for any wear of the socket. The upper end of the shaft is reduced, as at 25, and projec-ts upward through the head and has socured to it extcriorly of the head a bevel-gear 26, which meshes with a similar gear 2", carried by the shaft 13. The shaft 17 is provided at spaced intervals in its length with four series of orifices, two of which extend at right angles to the vertical axis of the shaft and the other two series obliquely to the axis at opposite angles, and these four series of openings are engaged, respectively, by mixing-arms 28, 2t), 30, and 31, the first two named series of arms being disposed at right angles to the vertical axis of the shaft and the last two at oppositely-disposed angles relatively thereto. These arms n1ay.be of any preferred contour in cross-section and are. herein shown as circular, are terminally disconnected, and extend approximately to the walls of the cylinder, thereby to insure the positive mixing of the concrete ingredients supplied to thehoppers.
In the operation of this invention cement will be supplied, say, to the hopper 11, and the sand to the hopper 11 whence these ingredients will be forced by the res ective conveyers to the feed-spouts 9, down t rough which they will escape onto the mixin -arms. As the shaft 17 is driven at a relative y high rate of speed it will be seen that the materials will be thoroughly mixed and agitated, and by the time they have reached the hopper 2 theyl will be perfectly incorporated.
rem the opper the Y pass out through the discharge-s out 3 to t e place of use.
Having t us described the invention, what is claimed is In a concrete-mixer, the combination with a casing, a head secured thereto and provided near its center with feed-spouts, hoppers carried by the head, a driven shaft journaled in the hoppers and carrying right and left hand threaded conveyers that feed toward the spouts, a vertical shaft arranged within the casin and driven from the worm-shaft, and radia l r and obliquely disposed mixing-arms earrie by the vertical shaft.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
CYRUS S. WERT.
