I To a ll 'whom it may concern:

Be it known that I, THoMhs S. LEAKE, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Preparing and Handling Concrete, of which the following is a specification. I

The object of my invention is to provide an improved apparatus for separating predetermined quantities of different lump, granular or pulverized materials from larger masses and feeding the separated submasses to devices adapted to receive them. More specifically the object of my invention is to provide a device adapted to measure and feed to a mixing device or to mixing devices, crushed rock, 'sand and cement in the proportions necessary for the forming of concrete. to certain improved structural'features and arrangements of parts as set forth in the following specification and claims.

Of the drawings:

Figure 1 is a side elevation of a measuring and mixing mechanism for concrete, having as a part thereof an apparatus embodying my invention.

Fig. 2 is an end view of the measuring apparatus shown in the upper part of Fig. 1, as seen from the right-hand side thereof.

Fig. 3'is a section on an enlarged scale taken on the line 3 3 of Fig. 1, looking in the direction of the arrow.

Fig. 4 is a plan view of the parts adjacent the mixing device shown at the lower left hand part of Fig. 1.

-Figs. 5, 6 and 7 are detail views of the links for controlling some of the valves.

in the drawings I have illustrated my improved mixing and feeding apparatus in combination with two devices for mechani call y mixing the concrete ingredients. And the mixing devices shown are provided with means whereby the mixed material can be expelled by compressed air and forced along My invention further relates Referringto the drawings-20 represents a bin for holding gravelor broken rock adapted to be used in formiilgconcretel On each side of the bin 20 aresand and cement bins 21 and below [the bins 21 are measuring,

chambers or receptacles 23. The receptacles 23-are connected with the bin 20 by means of supporting braces 64. The receptacles 23 are supported from'the other parts of the mechanism by means of- vertical columns 69, 69. Each ofthe bins" 20 is divided by a partition 48 into two compartments 49 and 50, clearly shown in Fig. 3. The larger compartment is for sand and the smaller .compartment 50 is for cement. At the bottom of each bin 21 is a gate orvalve 51 which simultaneously controls the openings at the bottoms of the two compartments 49 and 50.

This valve slides in guides 53. Each measuring chamber or receptacle 23'is divided by a partition 24 into compartments which correspond to the compartments 49 and 50.

discharge its contents. Preferably, how-' ever, the vessel V has not only one such chamber, but two, these being arranged on opposite sides of the partition 27 As the vessel is reciprocated these chambers are brought alternately into register with the bin opening, one being filled while the other is being discharged. Preferably, the vessel is mounted for oscillation about a horizontal axis and is shown as being mounted upon the rock shaft 28. This construction enables the movement of the vessel to be caused automatically by the weight of the material in one of the chambers. It will be seen that when one chamber is filled the weightof the material will cause the whole vessel to tilt horizontal pin 62 and each link 56 has pivotally connected to its end two parallel links 56 and 56*, the links 56 being in front, as viewed in Fig. 1, and'the links 56 being' behind. The links 56 and 56 are respectively provided with teeth 58 and 58", the

1 teeth being oppositely beveled so that one of them 58 will engage the corresponding pin 62 to pull but not push, while the other of them,.58 will engage the pin to push but not pull. Each link 56 is also provided with a second beveled tooth or lug 57 adapted to co-act with a stud 63 projecting from the wall of the corresponding receptacle 23. When the tilting vessel V is moved from the left hand position shown in Fig. 1, to the right hand position, the lugs 58 on the left hand levers 56 engage the left hand pins 62 and move the valve 51 of the left hand bin 21 to open position. After the valve has been opened the lugs 57 engagethe pins 63 and lift the levers 56 to disengage the teeth 58 from the pins. During the same movement of the tilting vessel and ofthe levers, the teeth 58 on the right hand levers 56 engage the right hand pins 62 and cause the valve 51 of the right hand bin 21 to be closed.

When the parts are moved in the opposite dlrectlons the steps which I have described are reversed and the right hand valve '51 is opened and the left hand valve 51 is closed.

The bottom of each measuring receptacle 23 is controlled by a gate or valve 66 adapted to slide in a guide 65. Two pairs of links 67, 67, are pivoted to the vessel at 68 on the front and rear and each is pivotally connected at its other end 65" to one of the valves 66. When the vessel V is in the left hand position the left hand valve 66 is open and the right hand valve is closed. When the vessel is moved to the right Hand position the left hand valve is closed and the right hand valve is open.

At the bottom of each receptacle 23 ther is also provided amanually controllable slide valve or gate 70 provided with a handle 71. This valve is intended to be suitably adjusted to regulate the rate of flow of materials out of the receptacle when the valve 66. is open.

Each chamber 25 of the tilting vessel V is provided at its bottom with a discharge duct or outlet, the two ducts or outlets being quite widely separated horizontally so as to permit the two chambers to discharge their with the chute.

contents at twohorizontally separatedplaces, as, for instance, into the two separated receptacles 32, 32. Each duct is closed at its lower outer extremity by means of a right hand chute alining with the vessel in I its right hand. position. Adjacent each chute 30 is a stop 74 arranged to engage the counterweights 72 and through them to move the gate 29 into open position as the corresponding part of the vesselcomes into alinement Stops 76, 7 6, are provided tollifirrnit the oscillating movement of the ves- 132 is an operating lever suitably pivoted at 133, and provided at its upper end with a handle 145. Pivoted at 140 is a bell crank having arms 141 and 142. The arm 142 is connected with the lever 132 by means of a link 143 and the arm 141 is connected to the tilting vessel V- by' means of a link 138 pivotally connected to the vessel. at 139. 144, 144, are stops or catches mountedon the main frame of the-mechanism and'adapted to engage the lever 132 to lock it with the tilting vessel in one position or the other.

101 is a dash-pot connected by a link 102 to the tilting vessel V in such a way as to retard its movement and take up shock.

32, 32, represent receptacles which are provided with suitable devices for mixing and agitating materials deposited in them. Water can be supplied to the receptacles from the reservoir 104. Discharge or delivery conduits 34, 34,- lead from the receptacles 32, and the contents of the receptacles can be forced out through the conduits by means of compressed air supplied through the various pipes which are shown. The valves for controlling the admission of materials to the receptacles 32 and the discharge of materials therefrom are prefer ably'connected to be operated by the same lever 132 which controls the tilting vessel V. It will be understood as before ointed out that the particular forms of mixlng devices which I haveshown constitute no part of my present invention and that therefore bins 21, and cement in the compartments 48 of the bins 21. The bin 20 is open at its bottom and the rock therefore flows out until one or the other of the chambers 25 (for instance the right hand one) is filled.

The gate 29 being closed prevents the rock flowing out of the chamber. At the same "time sand and cement flow from the compartments of. the bin 21 to fill the corresponding compartments of the receptacle 23.

It will be understood that while these steps are taking place the vessel V is held locked in its left hand position because of the engagement of the lever 132 with the right hand set of stops 144. However when the chamber 25 and the chambers in the re- .ceptacle 23 have all been filled an operator releases the lever 132 from engagement with the catches and the vessel V thereupon automatically moves under the weight of the rock on the right hand side to its right hand position. As this movement takes place the right hand valve 66 is opened and the right hand valve 51 is simultaneously closed, the

position also permits the left hand chamber' 25 to be filled with rock from the bin 20.

As the right. hand chamber '25 moves into alinement with the chute 30, the gate 29 is automatically opened and the rock, the sand and the cement are permitted to flow together into the receptacle 32, a partial mix ing of the three materials being thus immediately efi'ected, As soon as the materials have all passed into the right hand receptacle 32 the lever 132 can be again released,

this time from the left hand set of catches 144 and the parts 'will automatically move to permit the filling ofthe left hand receptacle 132.

By properly proportioning the chambers for the three kinds of materials any desired proportion of materials can be delivered to the mixing devices. By properly adjusting the valves 71, 71, the rate of flow of sand and cement-can be regulated to insure the best possible preliminary mixing with the rock. It will be noted that the entire oper-. ation is automatic except for the releasing of the lever 132 by the operator. The operator, however, needs to apply no power as the movement of the mechanism takes place by gravity.

I do not herein claim the features of novelty and invention incident to the' receptacles 32, the delivery ducts 34 and the other elements which constitute a combined mixing and conveying apparatus. These features are presented. and claimed in my copending application, Serial No. 396,270, filed October 7, 1907, of which this application is a division.
