I GHILDRESS, OF SPENCER, INDIANA.
CONCRETE-WEBER.
Specification of Letters Patent.
Patented Feb. 23, 1915.
Application filed May 21, 191%. Serial No. 840,027.
To all whom it may concern:
Be it known that I, DELANA R. CHILoRnss, a citizen of the United States of America, residing at Spencer, in the county of Owen and State of Indiana, have invented certain new and useful Improvements in Concrete- Mixers, of which the following is a specification.
This invention relates to concrete mixers, and more especially to that class of such mixers of the gravity type.
The objects of the invention are; to produce a simple, cheap and efficient mixer the operative parts of which will be actuated by the weight of the material to be mixed, and while so actuated, will thoroughly mix the ingredients of the concrete.
Another object is to provide means for sprinkling or moistening the mixture at a suitable time.
lVith these and such other objects in view as may hereinafter more fully appear, my invention consists in the novel arrangement and construction of parts described in the specification, more particularly pointed out in the claim, and which are shown in the accompanying drawings, wherein:
Figure l is a front elevation of the device. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical sectional V16W.' Fig. 4 is*a sectional View taken on the line 4i of Fig. 3.
Referring to said drawings by numerals:-A base, of any suitable form and mateiial, but, as here shown, composed of the side members 1 joined by the spaced connecting bars 2, has secured thereto at one end thereof, preferably by hinges 3, the mixer which is held in operative position by means of supports 4, the feet of which are adapted to rest on the side members 1 and the upper ends of which are pivotally secured to the mixer.
The mixer is composed of a back or slideway, which is divided into three sections, designated by 5, 5, 5"" for a purpose hereafter set forth. At either side of the back or slideway, and acting as a support for said back and the operative mechanism of the device, is placed a vertically disposed side member 6, to which are. suitably fastened the side pieces 6 which act as guards to keep the material from falling out. Suitably journaled in said side members 6, are horizontally disposed shafts 7, preferably four in number, each having one end ex tending slightly beyond, the side member and provided with a crank arm 8 to one end of which is pivotally secured a connecting rod 9 and on the other end of which is mounted a weight 10. Mounted upon each of said shafts 7 within said side members, are the circular retaining ends 11, between which, and suitably secured to the shafts, are vanes or paddle blades 12, for the purpose of forming rotary mixing members. Mounted at the top of'said mixer on a suitable platform 13, the forward end of which rests on suitable supports 14, is a hopper 15, provided with a dividing wall 16, to form separate compartments for the cement and gravel, each compartment having an apertured bottom, and a screen 17 being preferably provided in the gravel compartment to prevent the coarser gravel from being delivered to the mixer. The hopper, as will be seen most clearly in Fig. 3, is positioned just forward of the vertical diameter of the upper' shaft 7. The ordinary manually operable slides, not shown, may be provided in the bottom of the hopper for the purpose of regulating the amount of discharge therefrom.
At a suitable point, about midway of the mixer, is provided a platform 18, having supporting legs 19, upon which platform is mounted a suitable tank 20. tened in the lower portion of tank 20 is a. T pipe 21, the elongated cross arm of which is perforated to form a discharge nozzle.
Theback or slideway 5 extends below the two upper shafts 7 and serves the purpose of catching any material that may fall in passing through the upper mixer. The portion of said back designated by 5' is positioned-just below the lower one of the two upper mixers and is brought forward to terminate above the vertical radius of the upper one of the lower mixers, or shafts 7 The remaining portionof said wall 5" lies beneath the lower mixers, or shafts 7. I
The operation of the device is as follows z Material being discharged from hopper 15, will fall 'on the forwardly extending vane or paddle of the first shaft 7, thereby causing said shaft to rotate, which, through the connecting rod 9, will rotate the other shafts. Upon a sufieient rotation of the first shaft the material will fall from the vanes or paddles thereof to those of the next lower shaft, and from'them to the portion 5' of the back. The material will slide over Suitably fasthe portion 5' of the back under the action of gravity and at the same time Will be sprinkled with water from the discharge end of T pipe 21. It will then be delivered to the lower mixers or shafts 7 Where the same action as that just described takes place.'
Having described my invention, What I claim as new and desire to secure by Letters Patent, is
In a gravity concrete mixer, a suitable base, a mixer suitably secured to said base, comprising a hopper, rotary members below
