(Ja s' JOSEPH DORVVEILER. OF WEST BEND, IOWA.
CONCRET -MIXER.
Specification of Letters Patent.
Application filed June 20,1906- Scrlal No. 266,135.
To all whom it may concern.-
Be it known that I, JOSEPH DoawEILER, a citizen of the United States, residing at West Bend, in the county of Palo Alto and State of Iowa, have invented a new and useful Con crate-Mixer, of which the following is a specification.
This invention relates to concrete-mixers.
The object of the invention is to provide an apparatus which will in a rapid and continu ous manner mix sand and concrete in predetermined quantities and hydrate and discharge them as a thoroughly incorporated and finished product.
With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a concrete-mixer, as will be hereinafter fully described and claimed.
In the accompanying drawings," forming a part of this specification, and in which like 7 characters of reference indicate correspond ing parts, Figure 1 is a view in side elevation, partly in section, of a machine constructedin accordance with the present invention. Fig. 2 is a view in end elevation, partly in section. Fig. 3 is a sectional detail view through the mixing-hopper, taken on the line 3 3, Fig. 1. Fig. 4 is adetail view in plan of a rotary mixerused in connection with the apparatus. Fig. 5 is a sectional detail view taken on the 'line 5 5, Fig. 1, and looking in the direction of the arrow thereon.
The base of the machine comprises a pair of ordinary sill-beams 1, that sup ort two pairs of vertical beams 2, a pair 0 vertical beams 4, that areconnected by a cross-beam 5, and a pair of longitudinal beams 4 that connect the beams 2 and 4 and are disposed on the inner sides thereof. Supported by the longitudinal beams 4 is a mixing-trough 3, the upper edges of which are outturned to form flanges 3, that are bolted or otherwisesecured to the beams 4, and is thereby firmly supported in operative position. Supfported upon-the'beams 4", as by two pairs 0 nel-beams 6, is a casing 7, that is divided by apartition 8 into two hoppers 9 and 10, the former .of which is to receive sand and the latter cement, the escape of material from wheel 30, carried by t chana shaft 13, carrying two sets of beater-arms 14, one set being arranged in the compartment 9 and the other set in the compartment 10, the lower ends of the heaters being disposed to travel close to the mouths of the hop ers, as shown in Figs. 1 and 2. The sha t 13 carries on one enda bcvel-gear15, which is engaged by a similargear 16, carried by one end of a counter-shaft'17, journaled in suitable bearin s 18 in the conveyorcasing 22,-the other en of the counter-shaft having'secu'red to it a sprocket-wheel 19, which is driven by a sprocket-chain 29, as shown in Fig. 2.
The conveyor-casing 22, as shown in Fig. 2, is disposed on an incline and has combined with its lower end a feed-hopper 23, in which isarranged a screen 24, that is adapted to separate out from the sand trash and stones in the usual manner. There is also an agitator 20, arranged in the feed-hopper, the shaft of which carries a sprocket-wheel 21, which is engaged by a sprocket-chain 21,
driven from a sprocket-wheel 21", carried by the shaft 28. The elevator 25 is of the common bucket type and passes around sheaves or pulleys 26 and 27, disposed, respectively, at the lower and upper ends of the conveyercasing, the pulley 26 being mounted upon a shaft 28, journaled in suitable bearings on the base 1, and the pulley 27. being mounted upon the shaft 21*. q The shaft 27 is driven-by a sprocket-chain 29, which engages, res ctively, asprocketii: shaft 21 and two sprocket-wheels 31 and 32, carried byshafts 33 and 34, journaled beneath the hopper 7. Arranged beneath each of the hoppers 11 is a trough or box 35, within each of which is mounted a screw conveyer 36, carried by'the shaft '33 and a similar shaft 37, which are journaled in suitable bearings in the ends of the troughs. The shafts 33 and 37 each roject at one end beyond the trough, the s aft 33', as before stated, havin a sprocket-wheel 31 combined with it and the shaft 37 having a sprocket-wheel 38 combined with it. The shaft 33 carries a third sprocket-wheel 39, and the two sprocket- wheels 38 and 39 are. engaged by asprockeft-chain 40, which operates to drive the two screw conveyers-in unison.
Arranged below the troughs 35 is a hopper 41, into which the two trou hs discharge through openings 42 in their bottoms, and the hopper 41 projects into a circular recep- Iatented May 29,1906.
ICO
Mounted in a bearing 45, secured to the upper side of the mixing-trough, and in a bracket 46, secured to the under side of the hopper 7. is a vertical shaft 47, upon which is mounted a rotary mixing-disk 48, that carries a plurality of arms or heaters 49, which are dis posed tangential to the shaft 47, as clearly shown in Fig. 4. The object of this disk is to atch the sand and cement as it passes from the respective troughs and by centrifugal force throw 'it violently against the walls of the. receptacle 43, thereby to cause thorough mixing of the ingredients and also the breaking up of any lumps that might be resent and which would militate against t e production of a perfect concrete. The shaft '47 carries-on its upper end .a bevel-gear 50,which meshes with a bevel-gear 51, mounted on the 'shaft 34, the latter having secured to it a sprocket-wheel 32, which is driven by the sprocket-chain 29.
The mixing-trough 3 will, as shown in Fig. 5, be approximately semicircular in cross-section an is arranged on a slight incline, the discharge end of the trough having combined with it a spout 52. Mounted in a bearing carried by a bracket 53, supported by the trough and by a bearing formed in the head 53 of the trough, is a shaft 53, upon which is secured a plurality of obliquely-disposed arms 54-, that operate to feed the concrete throu h the trou h and also to break it up and mix it, so that by the time it reaches the spout 52 the ingredients will have been thoroughly commingled. The shaft 53 is driven from a pulley 55, that connects witha suitable source of power. (Not necessary to be shown.) The shaft 53 carries a sprocket-wheel 56, around which passes a sprocket-chain 57, and around a sprocket-wheel 58 on the shaft 33, and from this point all of the operative parts of the machine are actuated.
Arranged over the trough 3, at any preferred point of its length, preferably about midway thereof, is a tank 59 to contain water, connecting with which is a valved pipe 60, carrying a longitudinallydisposed sprinklin'g-pipe 61,which su plies water in requisite guantity to the troug thereby to effect hyration of the cement ingredients.
In {the use of the apparatus sand is supplied to the hopper 23 and is carried upward y the conveyor 25 and discharged into the hopper 9, while the cement is supplied from any suitable source to the hopper 10. The ingredients are then subjected to the beating action of the arms 14 and escape through the bottom of the ho pers 11 into the trough 35, whence they are ischarged by the screwcon- .veyers 36 to the hopper 41, thence to the rotary mixer 48, and thence to the trough, whence they are moved. along by the arms 54 and finally discharged.
The operation is rapid and continuous and the output of the machine is only limited by the speed at which its operative parts are driven and the amount of material supplied. When it is desired to stop the operation of the machine, the slide or valves 12 are closed or by regulating these latter elements the discharge of the materials can be controlled.
Having thus described the invention, what is claimed is 1. In a concrete-mixer, the combination of an endless conveyer, a feed-hopper forming a continuation of the lower end thereof and provided with a screen, a two-part dischargehopper arranged at the up er end of the conveyer and into one of who it discharges, ro-
tary boaters arranged within the discharge-' hoppers, means for removing the materials from the. discharge-hoppers, means for breaking up the mixed materials as they escape from the removing means, and a mixingtrough, including agitating and hydrating mechanisms, into which the materials discharge.
