' CEMENT-MIXING MACHINE.

No..s77,91s.

To all whom 'it may concern:

Be it known that FR'ANKLIN J. EMAL, a citizen of the United Pickrell, in the county of GageandState of Nebraska, has invented certain new and useful Improvements in Cement-Mixing Machines, of which the following is' a specification.

,This inventiony relates to improvements in cement mixing machines adapted for use .combining cement, sand or ot er granulated or powdered material with water or liquids for building purposes, and includes .means for forcing the feeding of the dry'materials, and for transmitting to the mixingldevices said material in graduated -or measured quantities; the invention has reference also to the production of a machine of few arts,

' particular of economical'construction, but whic will be eiiiective for the purposes designed. With these and ot er objects in View the invention presents a pointed outfbythe claims, and illustrated by the drawings, wherein,` Y

Figure 1 is a vertical, side view of the invention," partly. broken l v Fig. 3is a transverse, sectional view through the feeding boxes, as on line a b of Fig. 2; and Fig. 4 is a vertical, end view of the invention,

Referringnow to the drawings for a more description, the numeral 1 indicatesa rectangularly formed boX or receptacle, for convenience of description-called the machine-body, and is sup orted upon legs 2, and is preferably prov1 ed with a downwardly curvedy bottom .3. Y

I provide the shaft 4 having a mounting in L each end, wall ofthe receptacle at (points 'cen-" trally of the curved bottom 3, an upon` this shaft is securely mounted the worm 5. -The rear end of shaft 4 is extended to roject outside of the /tension is mounte j receptacle, and upont lex- -pulley 6. As thus described the worm is disposed longitudinally of and within the receptacle, adjacent the powers inner. wall of the curved bottom 3and is adapted to have a rotarymovement from rotation of shaft 4, pulley 6 receiving actuation from any suitableexterior source of I Vprovide the vertical partition 7 secured transversely betweenthe side walls of the machine-body., adjacent end 8, and between partition 7 and end wall'8 lof the machineV I l Specication of Letters Patent. Application tiled September 7. 1907.A Serial No. 391.786.

-provide vertical longitudinally of the each having side-edges 21 adapted to have a new combination and arrangement of parts as described herein, 14 and partition away. .Fig 2 is al Patented Feb. 4, 1908.

partitions 9 and 10 which e y adjacent each other and are disposed clos sides of the machine-body.

paralle with the he lower end 1-1 in Fi 3, and it terminates above the worm; and t e lower end of partitions 9 and 10 teiminate above end 11 of partition 7. As

thus constructed chambers or feeding-boxes l2 and 13v re formed, and partitions l9 .and 1() are dis osed so that one ofthe chambers .is larger t an the other.

I provide shelves 14 and 15 which extend downwardly-.divergent from .side walls 16 and 17, respectively, of the machine-body and terminate -adjacent the lower end of partitions' 9 and 10 to providev exit-.ports 18 'and 19. I provide slides c and d, preferably having convexed outer surfaces eXtendin machinebod an in slots 20 formed in' shelf slidable seating 9 andin shelf 15 and partition 10.

It intended by theforegoing constructaining cement and a lariger chamber 12 for holding sand, and, by're erenoe to Fig. 2 it Will be seen that when the slides are closed, `sand and cement would be contained in their respective chambers and would not pa'ss downward; but if the `slides are drawn so that -a part of the .chambers areuncovered, the1material can then pass downward upon the worm,.the amount which passes depending, of course, upon the distance the slidesare drawn.

, :In -order that the supply;

chambers

12 and 13 may e forced down- -ward upon the worin, and that the feeding may be measured and constant and regular, I employ

shafts

Shafts

23 and 24 are disposed parallel with sides 16 and 17 and have mountings for vone vof their ends in partition 7, their opposite ends being mounted in end 8 of the machinebody; and I vprovide leaves'or blades 25 secured upon 'shaft 23 4which extend out- Y Wardly therefrom and terminatev at .a distance from this shaft so' that eachv of said blades will pass closely adjacent to shelf 14A p and partition 9, When the shaft is rotated; and upon shaft 24 are secured leaves 4or shaft23, and these blades extend outwardly 26l of lesser width thanthose upon'

What I claim as my invention is,-

1.y In a mixing machine, of a containing receptacle having the transversely-disposed partition therein, a longitusame number of cogs. Upon shaft 23 and outwardly from gear-wheel 27 is secured l sprocket-wheel 21', and lupon shaft 4 isl mounted sprocket-wheel 22,-the latter being connected with wheel 21 by chain 30, and it will be understood that' when pulley 6 is l rotated in the direction indicated by the arrow in Fig. 4,

shafts

23 and 24 will thereby dinally disposed worm within the containing be rotated in opposite directions, and blades receptacle, 25 and 26 will tiereby be moved upward to connected with said partition to form an pass, respectively, partitions 9 and 10, and o ening therebetween and to form feedingwill be moved downward to pass,respectively, i cfiambers upon planes above said longitudishelves 14 and 15. i nally-disposed worm, saidv feedingchambers By the construction described it is' inbeing rovided with exit ports; a shaftwithtended that sand and cement contained, re-

chambers

12 and 13, will be forced or thrown in directions toward each other as they respectively pass openings 18 having lengthwise-extending blades thereon; a slidable closure traversing each feedingmore readily becoming chamber above the plane of each of said mixed. The proportionate amounts which l shafts;means to cause arevoluble movement pass, of each ingredient, depend of course, of said longitudinally-disposed worm, and upon the width of blades 25 and 26, the rotameans to cause a revoluble movement of tion of

A water tank 34 is secured upon the machine, and has an opening 29 communicating with the interior of the machine, and the sup ly of water may be conveniently controlled by means of the closure or slide 35, the slide having an angular stem- 36 passing upward and out of the tank and slidable in straps 37, the latter being secured upon the top of the tank. Any convenient exit port maybe provided for the outward passage of the material after becoming mixed, as pipe-opening 38.

It will be noted that an opening isformed 10 (Figs. 2. 3.) this opening extends the entire lengt of the feeding boxes, and is useful' for permitting an m'- being rovided with exit ports; .a shaft within eacifi .feeding-chamber disposed parallel with said longitudinally-disposed worm and having len thwise-extendin blades thereon; an outwarl -curved slidab e closure having an index thereon registerin with saidparti` tion and traversing each eeding chamber above the plane of each said shafts; means to cause a revoluble movement of said longitudinally disposed worm, and means to within the feeding-chambers.
