MIXING-MACHINE.
Specification of Letters Patent.
Patented Nov. 15, 1910.
Application filed March 30, 1909. Serial No. 486,764.
citizen of the United States, residing at Nunda, in the county of Livingston and State of New York, have invented certain I new and useful Improvements in Mixing- Machines, of which the following is a specification.
My present invention relates to a machine for mixing together the necessary ingredients to form concrete, and it relates more particularly to a charging-apparatus for charging the mixer with ingredients to form concrete.
My improved charging-apparatus is illus trated in the drawings forming a part of this specification in conjunction with what is termed a continuous mixer and it has for its primary object the provision of means to elevate the ingredients which form the concrete so that the operation of shoveling them into the elevated hopper can be dispensed with; the charging-apparatus being so arranged that the workmen need not lift the ingredients to the height of the mixingmechanism, which would not only require tiresome ph sical labor, but would also require consi erable more time to charge the mixing-mechanism with a given quantity of ingredients than by the use of the apparatus employed in this invention.
Another object of my invention is the production of a simple, effective, and contlnuously-operated charging-apparatus of peculiar construction, whereby the mixingmechanism may be charged with maximum speed.
To these ends, the invention consists in the combination of mixing-mechanism and a charging-apparatus into which the material to form the concrete is shoveled and to be charged into the mixing-machine without the necessity of manually lifting the material to the plane or above the plane in which the mixing-mechanism is placed, and it also consists in the construction, arrangement, and combination of parts to be hereinafter described and particularly pointed out in the subjoined claims.
In the drawings,--Figure 1 is a plan view of one form of mixing-machine to which m improved charging-apparatus is applie Fig. 2 is a front elevation of the charging apparatus with the retainer-rim removed. Fig. 3 is a rear view of the charging-apparatus disconnected from the mixing-machine. Fig. at is a central vertical section of the charging-apparatus showing a portion of the mixing-machine in section and two of the brackets supporting said charging-apparatus. Fig. 5 is a front elevation of a modified form of charging-apparatus with the retainer-rim removed. Fig. 6 is a rear View of said modified form of charging-apparatus. Fig. 7 is a central vertical section taken on line 7-7, Fig. 5 with the retainer-rim in a position looking in the direction of the arrow crossing said line.
Referring now to the drawings in detail, similar letters of reference indicate corresponding partshffl'ie several figures.
A designates the mixing-machine and B, B the charging-apparatus located at opposite sides of the mixing-machine. The charging-apparatus B is designed to charge one of the ingredients or materials to form the concrete into a feed-hopper b which delivers said material into a trough C having a feed-screw 0 adapted to feed the material forward into a mixing-receptacle D provided with mixing-mechanism d. The other charging-apparatus B is designed to charge a second ingredient into a hopper b, from which it is delivered into a trough G provided with a feed-screw 0 also adapted to feed the ingredient or material forward into the mixing-receptacle D.
In a plane above the hoppers b and 6 a third hopper E is provided into which a third ingredient, such as cement, is placed and while my improved charging-apparatus may be used to charge this hopper with cement, the manner in which the cement is delivered, makes this unnecessary.
Owing to the cement beingdelivered in bags, a platform F is provided on which a workman may stand and empty the bags into the hopper E as needed. The hopper E discharges into a trough G provided with a feed-screw g which feeds the cement forward into the mixing-receptacle. The mixing-mechanism d and the feed-screws c, 0 and g are driven by a suitable power-me dium through the intervention of transmission-mechanism H. The mixing-machine shown and described provides for mixing concrete consisting of three ingredients or materials such as sand, crushed stone or the" like, and cement; but for some classes of work sand and cement only are used, in which case a charging-apparatus may be used for one material only, or a charging apparatus for each of the materials used, and in some instances two or all of the ingredients may be charged into the mixing-mechanism with a single charging-apparatus.
While this invention can be applied to any form of mixing-machine whether a continuous-mixer, a batch mixer, or any other form of mixer, I have herein illustrated the same in connection with a continuous mixer and have applied one of my improved charging-apparatuses to each side of the machine, one being used for charging the mixing-mechanism with sand and the other for charging said mechanism with crushed stone or the like.
I will now proceed to describe one of the charging-apparatuses and since they are both similar, a description of one will sufiice for both. The charging-apparatus comprises a conical shell I having secured to its inner or small end a disk or head J provided with peripheral gear-teeth forming a gear K meshing with a gear-wheel is secured to a shaft L driven in any suitable manner or by the transmission-mechanism H. Said shell is supported by flanged rollers M rotatable on brackets m secured to the frame of the mixing-machine. A circular supporting-rim or track N is secured to said shell which travels on the rollers M, thus supporting the charging-apparatus in a secure manner. Any other suitable arrangement may be substituted for supporting and driving the charging-apparatus. The outer or large end of the shell has an outstanding flange O to which is secured a retaining-rim P, also substantially conical and serving with the shell of the charging-apparatus to form a substantially continuous or circular V-shaped trough into which the workmen shovel the material to be delivered to the mixing-mechanism.
Secured to the shell I is a plurality of troughs or buckets It, substantially of U- shape in cross-section and inclined to correspond to the inclination of the shell with their inner ends projecting through openings R formed in the disk of the head J. These troughs are inclined forward when in a plane beneath the horizontal center in the shell or casing, and rearward when in a plane above the horizontal center.
A standard S is secured to the frame of the machine and has a spindle s fastened therein which extends through the hub of the disk J and has collars s secured thereto which lie on opposite sides of said hub, thus providing an axis upon which the chargingapparatus may rotate and: atthe same time assisting the flanged rollers M in retaining the apparatus in proper osition. I
As clearly shown in hig, 4,-t he lowestpoint of the apparatus is close proximity to the ground so that the workman shoveling the material into the charging-apparatus can do so quickly and conveniently Without lifting the material to a height requiring very much effort. The material is retained in the shell by the retaining-rim P and when said shell rotates, the trough or buckets R carry the material upward and as they are brought above the horizontal center of the charging-apparatus they assume a position inclining toward the mixing-machlne and cause the material to move toward the inner ends ot the troughs to be discharged from the apparatus as said ends pass over the hopper leading to the feed-screw.
hen the charging-apparatus is supplied with two or more kinds of material, the material is given a preliminary mixing in the apparatus as it is carried upward to its discharging point so that it is delivered into the receiving hopper as a mixture.
In the modifications shown in Figs. 5 to 7, the rear end of the shell I is left open and a gear-rim T secured to said end and adapted to mesh with a gear-wheel driven in any suitable manner. In this construction, a spider U is provided having a hub is through which the s indle 8 passes. The troughs are arrange similar to those described in the preceding figures and discharge the material into the receiving hopper, as clearly shown in Fig. 7
Having thus described my invention, wha I claim is,
1. A charging-apparatus for mixing-now chines comprising a shell of the shape of a truncated cone closed at its small end and provided with a circular series of gear-teeth at said end, a retaining-rim secured to the large end of said shell, and delivery-troughs secured to the inner side of said shell and extending out through the closed end of the same.
2. A charging-apparatus for mixing-machines comprising a substantially conical casing, a disk closing the small end of said casing and having peripheral teeth thereon and openings adjacent the wall of said casing, a retaining-rim inclined in a direction opposite to that of the wall of said casing and secured to the large end of the latter, and delivery-troughs secured to the inner side of said casing and extending from said rim through said openings.
3. The combination with a mixing-machine, of a charging-apparatus rotatably mounted and adapted to deliver material from a low point to a higher point and discharge the same into the mixing maohine, said apparatus comprising a conical casing,
