BATOHER.

Application filed February L, 1325. Serial No. 85,989.

The present inventionrela-tes to measuring and dispensing devices, and aims to, provide a novel and improved device of that kind for measuring and dispensing sand, crushed stone, or similar materials, the device being particularly intended for proportioning the aggregates for concrete construction, by dispensing the batches of sand and stone, al-

, though the device may be used for other purand etlicient manner, and, a still further object in this connection is the provision of such gates or valves and controlling mechanism therefor whereby the filling and emptying of the measuring chambers may be alternated to facilitate the operation.

A still further object is to provide means whereby the batcher aud storage bins or hoppers may be vibrated or agitated so as to facilitate the flow of materials from the stor age bins into the measuring chambers, thereby preventing the materials from arching or bridging and also compacting the materials in the measuring chambers, to compensate for bulking, to eliminate voids, and to provide uniformity of quantities measured.

lVith the -foregoing and other objects in View, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as

hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

'The invention is illustrated in the accompanying drawings, wherein Figure 1 is an elevation of the improved batcher.

Fig. 2 is an enlarged median vertical sec- Figs. 8 and. 4 are sections on the respective lines 3-3 and 14: of Fig. 2.

Fig. 5 is a fragmentary elevation of the butcher illustrating the use of an electric motor .t'or operating the gates.

The bins or hoppers and 11 for the sand and crushed stone, respectively, or

other materials for which the batcher is intended, are mounted in a structural supporting frame12, and said hoppers are built together with a partition between them. The structure is rendered portable by ground wheels 13 carried by the frame 12, as disclosed in the copeuding application Serial No, 65,357, filed October 28, 1925.

The hoppers 10 and 11 have the depending discharge spouts 14 and 15, and the meas uring and dispensing chambers are suspended below said spouts. Thus, a horizontal plate 16., through which the spouts 14 and 15 extend, is secured to said spouts and the hoppers. and parallel beams 17 are secured,

to opposite edge portions of the plate 16 and are connected at theiropposite ends by the cross members 18, thus providing a frame surrounding the spouts 14 and 15.

Adouble slide gate or valve 19 is slidable in the frame 1718 immediately below the spouts '14 and p and 21 to re ister alternatelywith the respective spouts 14 and 15. Thus, referring to Fig. 2, when the gate 19 is moved to the right it closes the spout 14: and the opening 21 registers with the spout 15 for the flow of crushed stone through the spout 15 and opening 21. the left it closes the spout 15 and the opening registers with the spent 14 for the dis charge of sand from the hopper or bin 10. T he. gate 19 comprises a plate of sheet metal, and has upturnedflanges 22 along its side edges carrying rollers or wheels 23 that. are

movable on rails 23 secured to the beams 17 thus mounting the gate 19 for free reciprocatory movement in the frame below the spouts of the hoppers.

The sand and stone measuring chambers 24 and 25, respectively, are disposed below the spouts 14 and 15, respectively, and their lower portions are tapered, as at 26, to the lower discharge openings of said chambers, the chambers being open at the top. Throat members 27 and 28 depend within the chambers 24 and 25,, respectively, and are sus- 15, and hasthe openings 20.

lVhen the gate 19 is moved toward pended from the frame, said members having flanges 29 at their upper edges secured to the beams 17 of the frame. As shown, the member 27 is cylindrical, while the member 28 is cylindrical at its upper end and its lower portion is flared because the chamber 25 is of larger diameter than the chamber 24.

The chambers 24 and 25 are adjustably supported from the frame in order that the batches of sand and stone may be regulated according to the proportions desired. Thus, hanger rods 30 are suspended from brackets 31 secured to the outer sides of the beams 17, and extend through brackets 32 carried by bands 32 secured to the upper edge portions of the chambers. As shown, the rods 30 are screws engaging downwardly through the brackets 31 and having heads at their upper ends seating on said brackets 31. The brackets 32 are slidable on the rods 30 in order that the chambers may be raised and lowered, and nuts 33 are threaded on the rods to support the chambers in different vertical positions, the brackets 32 seating on said nuts. Thus, by adjusting the chambers upwardly and downwardly the batches measured and delivered thereby will be decreased and increased in volume, respectively.

The double slide gate 19 moves between the spouts 14 and 15 and the throat members 27 and 28, to control the flow of materials from the hoppers into the measuring chambers alternately.

The discharge of the materials from the measuring chambers is controlled by gates 34 and 35, respectively, which are secured on levers 36 fulcrumed, as at 37, to the chambers 24 and 25. The fulcrums 37 are located at opposite sides of the chambers so that the materials from both chambers are directed downwardly in substantially the same vertical line. The levers 36 have weights 38 at their outer arms opposite to the gates 34 and 35, respectively, which are shown as screw-threaded on the tail screws 39 of said levers, in order that the weights may be adjusted to regulate the pressure on the gates tending to close them. The weights 38 tend to swing the levers 36 so as to seat the gates 34 and upwardly against the lower edges of the chambers '24 and, 25, respectively,

4 across the discharge openings of said chambers.

In order to operate the gates, bars 40 and 41 are pivotally connected, as at 42, to the opposite ends of the gate 19 and pass slidably through the cross members 18, and the outer ends of the bars 40 and 41 are connected by links 43 with depending levers 44 that are fulcrumed at their upper ends to the hoppers or frame 12, as seen in Fig. 1. As shown, there are two levers 44 located at opposite sides of the frame, in order that the gates may be operated from either side, although a single lever will sufiice if desired.

By swinging either lever 44, the gate 19 is readily reciprocated.

The operation of the discharge gates 34 and 35 is controlled by the movement of the gate 19. For this purpose, vertical screws 45 are located at opposite sides of the measuring chambers, and sleeves 46 are slidable loosely on said screws and are pivoted, as at 47, to the arms of the levers 36 having the weights 38. Upper and lower nuts 48 and 48 are adjustable on the screws or rods 5 at the upper and lower ends of the sleeves 46, so that said sleeves are confined between said nuts, thereby causing the sleeves to move upwardly and downwardly with the screws or rods. The nuts 48 and 48 may be adjusted upwardly and downwardly on the screws to adjust the sleeves on the screws, according to the vertical adjustments of the measuring chambers on the rods 30. The upper ends of the screws 45 are secured to cross heads 49 which have upwardly extending slotted arms 50 slidably engaging studs or pins 51 on the opposite sides of p s of vertical flan es or members carried b cross angle irons er members and connected to the beams 17, thereby guiding the heads 49 and upper terminals of the screws 45 for up and down movement, with the arms 50 located at the opposite sides of the flanges or members 52. Levers 55 are fulcrumed, as at 56, between the flanges 52 immediately below the bars 40 and 41, and their lower arms are connected by links 57 with the heads 49, thereby providing toggles. Rollers 58 are carried by the upper arms of the toggle levers 55 below the bars 40 and 41, and said upper arms of the lovers are bifurcated so as to straddle thebars 40 and 41 from below. The cross members 54 have seats against which the toggles seat when they are straightened out and moved slightly be yond straight line position, as seen at the right in Fig. 2. The toggles are controlled by the bars 40 and 41 which have notches GO in their lower edges to receive the rollers 58, and said bars have abutments 61 at those edges of the notches farthest from the gate 19, to contact with the rollers 58.

In order to jar or vibrate the storage bins and batcher, weights 63 are carried by the ends of the gate 19 and are adapted to strike the angle irons or cross members 53 at the opposite limits of movement of the gate 19, to shake the structure.

The number of batches is recorded by means of a suitable recorder 65 mounted at any suitable point on the frame and operated by one ofv the moving parts. As shown the recorder 65 is operated by an abutment or lug 66 on the bar 40.

It will be noted that with the exception of the levers 44, the device is attached to and suspended from the hoppers or bins, and the device may be used on different hoppers or upwardly to swing bins. The frame 12 supports the hoppers and batcher so that a truck may be backed or run under the catcher to receive the materials, although the materials may be received from the n'ieasuring chambers in any suitable receptacle.

In operation, supposing that the gate 19 is slid toward the right, as seen in Fig. 2, so as to close the spout 14 and open 'the spout 15. This will cut off the chamber 24- from the hopper or bin 10, and the chamber 25 which was previously emptied will be filled by the flow of stone from the hopper 11 through the spout 15 and throat member 28 into the chamber 25.

When the gate 19 reaches the end of its movement toward the right, the right hand weights 63 contact with the right hanu angle iron 53, so as to jar the storage hoppers and prevent arching or bridging of the materials over the spouts. During the movement of the cut-off filling gate 19 toward the right, as aforesaid, the gates 34 and 35 are con trolled automatically to release the gate 34 and close the gate 35. Thus, as the bar 41 moves toward the right, the right hand lever 55 will be swung from the dotted line pos' tion to the full line position, as seen in lug. 2, thereby straightening out the to; .'e downwardly, and the lever 55 is swung to move the toggle slightly beyond straight line position, thereby locking tl e right side screw 45 and head 49 against upward movement. The right side nut 48 and sleeve 4" th fore move downwardly to close the gate 35 and lock it in closed position during the i'illing of the chamber 25. toward the right will result in the abutment 61 thereof contacting with the roller 58 of the left hand lever 55, and swinging said lever to the position shown in Fig. 2, thereby breaking the toggle by swinging or moving same away from the seat 59. The left side nut 48 and screw 45 are therefore moved the gate 34 open downwardly assisted by or material bearing on the gate 84. As soon as the sand has been discharged from the chamber 24, and the chamber 25 has been filled, the gate 19 is reversed by moving'it toward the left, as seen in Fig. 2, which will cut off the chamber 25 from the hopper 11 and bring the chamber 24 into communication with the hopper 10 through the opening 20 of the gate 19. When the gate 19 reaches the end of its movement toward the left, the weights at the left end of the gate 19 will contact with the left hand angle iron 53, to jar the storage hoppers and loosen the materials therein, to prevent the materials arching or bridging. lVhen the gate 19 is moved toward the left the roller 58 of the left hand lever being in the notch of the bar 40, will result in said lever 55 being swung counter clockwise, as seen in Fig. 2,

The bar 40 moving.

the wei ht of the sand thereby straightening out the toggle and moving the left side screw 45 and sleeve 46 downwardly. The left hand toggle is therefore moved to and slightly beyond straight line position, so that the gate 34 is thereby locked in closed position so as to support the sand in the chamber 24 durin the filling of said chamber. The notch 60 or the bar 40 moves to the left beyond the roller 58 of the left hand lever 55, just the same as the notch 60 of the bar 41 is moved to the right of the right hand lever 55, as seen in Fig. 2, thus preventing the gate 34 from being unlocked until the gate 19 is moved to its right hand position. During the movement of the gate 19 toward the left, the abutment 61 of the bar 41 contacts with the roller 58 of the right hand lever 55, thereby swinging said lever from the full line position to the dotted line position, as seen in Fig. 2, and breaking the toggle and moving the right side screw 45 and sleeve 46 upwardly, to swing the gate 35 open, assisted by the downward pres sure of the stone in the chamber 25 on the gate 35, permitting the discharge of the stone from said chamber 25. As soon as the chamber 25 has been eu'iptied and the chamber filled, the gate 19 is moved toward the right to close the gate and thereby repeat the operation as above described.

lhebatcher thus enables the materials to be readily measured and discharged. Thus, a driver of a truck may run or back the truck under the batcher, and by moving either lever 44 one chamber i emptied into the truck, and either lever 44 my then be operated so that the other chamber is emptied into the truck. This may be repeated when more than one batch may he carried by the truck The driver of the truck may therefore 0 without requiring a special batcher, and the loading of the trucks is facilitated to save time and. expense.

F ig. 5 illustrates how an electric motor may be used for operating the butcher. Thus, the 19 connected by a link 43 with the crank of a shaft geared to an electric motor 71 supported by the fra1ue12, whereby the motor may be operated for reversing the gate 19, the same as acrom- I plished by the lovers 44.
