CEMENT-MIXER.
SPECIFICATION forming part of Letters Patent No. 787,071, dated April 11, 1905.
Application filed May 16, 1904. Renewed February 2'7, 1905. Serial No. 247,556.
Be it known that l, CuAnLEs BnExT, a subject of the King of Great Britain, residing at R at Portage, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in (lement' hfixers, of which the following is a specification, reference being had therein to the accompanying drawings.
The invention relates to useful improvements in cement-mixers, particularly in the construction, arrangemcnt, and combination of parts, as more fully hereinafter described, and particularly pointed out in the claims.
In the drawings, Figure 1 is a side elevation of my improved mixer. Fig. 2 is a hori- Zontal section on line $.12, Fig. 1. Fig. 25 is an end elevation looking from the right-hand end of Fig. l: and Fig. 4 is a vertical crosssection upon line 1 1 Fig. 2.
A is the base, having the standards B, in which is supported the casing (7, which I have shown of U-shaped sheet metal reinforced by the U-shaped bands I).
I and F are the end plates for the casing, being bolted onto the flanges on the end bands l). The end plate E has preferably cast integral with it a bracket f}, in which is the central horizontal bearing ll for the shaft l, on which i have shown (hive-pulley l. The end plate F has cast,preferably integral with it, a casing J, forming feed-chambers, and to the outer end of this feed-chamber casing is secured an end plate K, having cast integral with it, preferably, brackets ll, upon which are provided the bearings .\l and N, the bearing M being in line with the hearing If and forming a support for the other end of the shaft f.
In the bearing X is the stub-shaft f supported in the bearing and projecting both sides thereof, its inner end having secured to it a sleeve 1/, having thereon a worm-flange I). This worm-flange is in a feed-chamber P in the extension J, and the feed-chamber P is 1 separated from the chamber Q by a partition H. axis of the shaft f, and on the shaft l within The chamber Q is arranged about the 1 flange or a worm T thereon. The shafts I and project beyond the bearings M and N, respectively, and upon, these two shafts are the gear-wheels U and V. These two gearwheels are dctachably secured to the project ing ends of the shafts, so that they may be readily removed and other intermeshing gears of different ratios be placed thereon.
At the top of the extension J, I arrange the two hoppers c and (I, the lower ends separated by the partition 0, the hopper 0 being adapted to deliver material to the chamber P and the hopper (1 being adapted to deliver its material to the chamber Q.
The shaft l in its middle portion is squared, as shown in Fig. 4, and upon the squared portion of the shaft are secured the blades \V, theseblades being preferably cast integral with the clamping-plates \Y, which are bolted on the shaft, as plainlyshown in Fig. 4:.
In the top of the casing I provide a perforated feed-pipe X, which is supplied by water from any suitable source through the supply-pipe X.
At the lower end of the hoppers c and (Z I arrange cut-off gates 72 and i.
The parts being thus constructed they are intended to operate as follows: The cement is put in the hopper c and the sand in the hopper (Z, the gates l2 and i being open. Motion is imparted to the shaft 1 through the pulley f, and this will rotate the blades V with the shaft and also the worm T on the sleeve S in the saiul-chamber Q. Through the gears V and U the shaft will be rotated and the worm I) in the cement-chainber P will likewise be rotated, and thus the sand and cement. will be fed into the casing I and will be fed therethrough by the blades \V, at the same time being thoroughly mixed. After the sand and cement have been thoroughlymixed in the first part of the mixing-chamber the water will be turned on and the cement will be moistened and more thoroughly mixed in the second half of the casing and will finally be dis i harged through the d ischarge-spout Z at the lower end. \Vhen it desired to change the speed of the worms in the sand the chamber Q is a sleeve S, having a worml and cement chambers, I simply detach the gears U and V and supply their places with others of different proportionate size.
By arranging one worm directly on the main shaft of the machine, which carries the beaters and acts as the drive-shaft, and by making the gears detachable I not only simplify the machine, but am enabled very readily to change the speed at which the material is fed into the inixingchainber.
The construction described is cheap and simple to manufacture and is very eflicient in producing the desired mixture.
What I claim as my invention is- 1. The combination. of a mixing-chamber, the end plate F at one end, the sand-chamber Q and the cement-chamber P secured to said end plate, the shaft I extending centrallythrough the mixing-chamber and centrally through the sandchamber, bearings at the end of said shaft, a bearing at the end of the cement-chamber, shaft 0 in said bearing, the worm b on said shaft in said chamber, the worm T on the main shaft in the sand-chamher, the beaters or blades W on the main shaft within the mixing-chamber and the intermeshing gears on the shafts I and O, for the purpose described.
2. The combination of a casing, the main shaft extending therethrough, bearings H and N to which said shaft is journaled at its ends, the blades on the shaft within the casing, the sand-chamber Q between the bearing N and the casing, the worm T on the main shaft in I WVitnesses:
