Specification of Letters Patent.

Patented Oct. *7, 1919.

Application filedApril 25, 1919. Serial No. 292,593.

To all whom it may concern;

Be it known that I, LEMON M. REED, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Mixing Apparatus for Making Cementitious Products, of which the following is a specification.

This invention relates to improvements'in distributed over an open box or receptacle for receiving the resulting cementitious product.

Another object is to render said apparatus highly eflicient and reliable in the performance of its functions and simple and durable in construction.

I Another object is to have said apparatus comprise simple and eflicient means for wet-- ting or moistening the hereinbefore mentioned mixture during its passage and in proximity to the aforesaid receptacle.

With these objects in view, and to attain any other object hereinafter appearing, this invention consists in certain features of construction, and combinations and relative arrangements of parts, hereinafter described in this specification, pointed out in the claims, and illustrated in the accompanying drawings. r p In said drawings, Figure 1 is a vertical longitudinal section of apparatus embodying myinvention. Fig. 2 is a vertical transverse section taken along the line 2-2, Fig. 1, looking in the direction indicated by the arrow. Fig. 3 is a vertical'transverse section taken along the line 3+3, Fig. 1, look ing in the direction indicated by the arrow. Fig. 3 is drawn on a larger scale thanthe preceding figures, and portions are broken away in Fig. 3 to reduce the size'of the drawmg.

' eferring to Fig. 1 of said drawings, 11 and 12indicate two hoppers for "receiving drysand and dry hydraulic cement respecti-ve'ly .Said hoppers are adapted to dis charge downwardly and arranged side by side and supported from and rendered rigid with stationary framework 13 in any approved manner.

resting on the floor 15. Two laterally spaced substantially horizontal and substantlally parallel rotary conveyers 17 and 18 are arranged under the outlet of the different hoppers 11 and 12 respectively. The

- conveyers 17 and 18 are operatively mounted on correspondingly arranged shafts 19 and 21 respectively which are supported from the framework 13 and operated in any approved manner, and eachconveyer has peripheral chambers 20 spaced eircumferentially of the conveyer and arranged to communicats with and receive material from the outlet of the superimposed hopper during the rotation of said conveyer. Said shafts are of course rotated in the direction required to rotate the conveyers 17 and 18 in the direo tion necessary to feed materials received from the hoppers into the space between the lower portions of the conveyers. Means for effecting the operation of said conveyers are too well known in the art to require further description and illustration in this specific-ation. Adjacent each conveyer (see Fig. 1) isa guard which extends from the outlet of the hopper arranged above said conveyer downwardly circumferentially of the inner side of the upper portion of and is arranged in close proximity to said conveyer. Each guard 28 is arranged and adapted to cover a chamber 20of the conveyer circumferentially of which said guard extends, and said chamber does not discharge the contents thereof during the operation of the conveyer until the chamber has begun to movebelow the lower end of said guard. The cementconveyen 18 is shown as having twice as -many chambers 20 asthe sand-conveyer 1'1, and each chamber of the sand-conveyer'is shown as having over twice the capacity of a chamber ofthe cement-conveyer, and the relative operation of said conveyers is such astofeed: cement and sand, 1n the desired proportion, into the space between thelower portions of the conveyers. are located atthe outer side of the'dlf'ferent Two guards 24 conveyers respectively. Each-guard 24 extends. from the outlet" of the adjacent hopper eircumferentiallyof theadjacent conveyer and isarranged and adapted to cover a chamber 120 of said. conveyerxllpon the Said framework is shown fioor'l5, below the conveyers 17 and 18, is

an open box or receptacle 25, and said conveyers are arranged far enoughabove said receptacle to permit the arrangement, be tween said receptacle and said conveyers, of

apparatus en'iployed in mixing the sand and' cement during the passage of said materials from sa-id conveyers to said receptacle."

26 which is open at its upper and lower ends and arranged between the receptacle 25-and the conveyers l7 and 18. Preferably said casing is enlarged in thickness, as at 27 at its lower end and suspended by upright links 28 from brackets or members 29 which are rigidwith and project fromthe hoppers 11' and 12 and are consequently rigid with the framework 13. 2 At each side of said casing are two uprightlinks 28 which are pivoted at their lower ends, as at 30 to said casing: and pivoted at their upper'ends, as at 31', to the link-supporting members 29. Eachlink 28at each side of the casing 26 is arranged opposite a. corresponding llnk at theopposite side of the casing, as shown in Fig. 2.- The pivotal connections between the casing 26 and the links 28 and the pivotal members 31 connecting said link to the liiiltsiipp orting members 29 are parallel with the conveyers 17 and 18. The casing 26 is therefore shown arranged and supported as required to render'it capable of being reciprocated in a substantially horizontal plane. A crank-shaft 32 is supported from the top; portion of the framework 1 3 at on'e end of said framework, and saidshaft is parallel with the conveyers 17 and 18, and preferably a link 28 at eachside of the eas ing 26 is operatively connected by a pit-man 33 with a crank 3t 01": said shaft which is rotated in'any approved manner, duringthe operation-of the conveyers, to effect a rapid reciprocation of said casing. The framework-13 is provided with a pair ofsubstantially horizontal and substantially parallel laterally spaced bars 36 whichare arranged internally of thecasing 26 and extend longitudii'ially of the travel of said casing. The

-bars36 are supported'from and rigid with bracl'rets with -which the top portionof the framework 13 is provided. Said bars aretspaced downwardly from the conveyers 17'and18'and upwardly fromth'e lower end of the casing '26, and the relative'arrange- 'ment of theparts is such as to; permit moveinent'ofvsai'd casingl longitudinally, of said barsin opposite directions alternately by the hereinbefore described operative connection of: said casing-with the-'crank-shaft 32. The

brackets 37 at each end ofwthe pair of bars 36 are=tied together-by bars 38 so as torrenden thecbars 36 adequately rigid. The bars 36are provided: with a row of four inclined metal: plates arranged thereon inter- "wardly. By the construction hereinbefore ranged transversely: of said row.

nally of the casing 26, and said plates are rigid with and spaced and extend longitudinally of said-bars. Adjacentplates39 slope downwardly in the direction of opposite ends respectively of the bars 36 and are arranged to receive materials to be supplied from above and to be mixed during the reciprocation of said casing, andthe two inner plates of said row of plates diverge updescribed it will be observed that each outer plate and the adjacent inner plate of said row of platesconverge upwardly and that the bars 36 and the said platesare supported independently of the casing 26 and are stationary, being rigid with the frame-Work 13. Means wherebythe materials delivered by the conveyers 17 and 18 to the space between the lower portions of said conveyers are conducted or fed over and to and between the stationary plates 39 comprise two downwardly diverging inclined metal plates 40 supported from the casing 26. The end walls of said casing preferably do not extend upwardly as far as the bars 36, wherea the side walls of said casing ex teud above said bars-and above the plates 40. The plates l0 are arranged over the bars 36 and meet attheir upperends and have flanges 11- secured to the casing. 2 in any approved manner. The plates 39 of the bars 36 are therefore arranged toreceive materials from the plates l-0 duringthe reciprocation or actuation of the casing 26 longitudinally of said bars; Each plateO in the central position of the casing 26 (see Fig. 1) has itsupper end under the central portion of the space between the lower portions ofthe-conveyers 17 and 18 andover the space between the lower ends of the inner upwardly diverging plates 39, and has its lower end in posi'tion over thespace between two adjacent upwardly converging plates 39. 'Tlierelative arrangen'ient oi the parts is such that the stationary plates 39 are arranged wholly internally of the casing 26 in anyposition of theca-sing. Each plate oi therow of plates 39 has a flange 42 which projects substantially vertically downwardly from'the upper end of said plate and is ar- The flanges 412- of adjacent upwardly converging 7 plates- 39 are helpful in guiding: materials verticallydowmvardly through the space between said flanges. The plates 39 have '120 flanges 13' securedoto' the casing'26 in any approved manner. Said casing: is: provided internally and below the stationaryi plates 39Kwith' meansfor retarding. the movement oi materials from said plates and from the spaces between said plates to the lower end=of thecasing and for further mining and distributingsa id materials during said movement, and-said means comprise three vertically: spaced substantia y p e 3 0;

of inclined metal plates 45 arranged internally of and supported from and movable with the casing. The rows of plates 45 are arranged longitudinally of the bars 36, and adjacent plates of each row of plates 45 slope downwardly in'the direction of opposite ends respectively of said row. Adj acent downwardly converging plates of each row of plates 45 are; spaced attheir lower ends. Adjacent upwardly converging plates of the upper row of adjacent rows of plates 45 extend into close proximity to each other and preferably meet at their upper ends and.

have their upper portions arranged over the space between the lower ends of two adjacent downwardly converging plates' of the lower row of said adjacent rows of plates. Each of adjacent upwardly converging plate of each row of plates 45 is provided at its upper end with a substantially vertically upwardly projecting flange 46 extending transversely of said row. The plates 45 have flanges 47 secured to the casing 26 in any approved manner. The flanges 46 of adjacent upwardly converging plates of each row of plate 45 abut against each other and form a partition, and each partition thus formed at the top of the bottom row of plates 45 is substantially in line vertically with a partition formed at the top of the top row of plates 45. Each partition formed by abutting flanges 46 is helpful in efiecting a substantially equal distribution of materials to the plates diverging downwardly from said partition.

Means for wetting 0r moistening the dry mixture of sand and hydraulic cement, upon the passage of said mixture from the plates of the bottom row of plates 45, comprise perforated pipes 48. Preferably the casing 26 is provided over the space between the lower ends of adjacent downwardly converging plates of the bottom row of plates 45 with a substantially horizontal pipe 48 arranged transversely of said rowand supported by and movable with the casing 26 and (See 3) provided at its bottom with perforations 49which are spaced at short intervals longi ftudinally of the-pipe and airangedto discharge downwardly into said space, and ob-- pipe 53 having a valve 54 upon opening which water is supplied from said supply pipe through the branch-pipes 52, tubes 51 and pipes 50 to the pipes 48.
