To all fac/1,0m it may concern.'
Be it known that I, GEORGE I-I. MAGLEAN, a citizen of theUnited States, residing at New Haven, in the county of New I-Iaven and State of Connecticut, have invented a t new and useful Improvement in Batch- Measuring Hoppers; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference umarked thereon, to
be `a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, inf
Fig. 1 a top or plan view of a batch-measuring hopper constructed in accordance with my invention. Y
Fig. 2 a front view loi" the same.
Fig. 4 an end view of the same in the discharge position.
This invention relates to improvements in batch-measuring hoppers for use in loading sand and stone upon trucks for transportation to the placerwhere theyare to be mixed. In the construction of concrete pavements and other concrete work, it is a common practice to draw the dry batches, consisting of the proper proportions of sand and stone, from bins in auto trucks, the bodies of which are divided into compartments by partitions arranged transversely between the sides of the body. Each of these compartments is adapted to contain'a predetermined batch of stone and sand, together with a correct proportion of cement, and the object of this invention is to provide a hopper which will deliver these batches to a truck, and the invention consists in the construction as hereinafter described and particularly recited in the claims.
In illustrating my invention, I have shown a measuring hopper designed for a three-compartment truck, but it will be understood that two compartments only may be employed for loading two-compartment trucks.
As shown, the hopper 5 is divided into three compartments, and in each compartment is a partition 6 forming three sets of chambers 7 and 8, one chamber of each set being adapted to receive sand and the other stone. The partitions 6 may be made adjustable, so as to vary the relative sizes of the chambers: 7 Aand 8. The chambers 7 and 8 of each compartment open into imOuthS' yS-Gred 11.0 opposite .ends of the kenner are arms 10,-Whch proj-ect below the lower end of the hopper and aremounted upon a shaft 11 supported ,in brackets-12 secured to inclined braces 13 formingl part of. the framework 14, `which Aincludes a platfom 15, through ywhich the' hopper may kbe i loaded from any source `of sup-ply.` The mouthsfof the hopper are closed by a gate 16k extending across .them 1nd lberend. each and.,
this sate being Secured, at its upper edge to the hopper, `by hinges 17. The arms l() are arranged in rear of a .vertical plane through the hopper, so .that the tendency of the hop:- per is to tip forward. This is resisted, while the loading operation takes place, by cables 18, which are fixed tothe yends of the gate 16, and pass over sheaves 19 mounted lin the frame 14 to a bar 20, .this cable 18 also holding the gate in the closed position. Connected with the arms 10 are cables 21s `which extend over sheaves 22 te the bar 2Q, and on the bar are ,counterfbalancing weights 23. It will be noted that when the horrers in its `elevated or loading paston" as shown in Fig. 3 of the drawings, that the cable 18 is taut, so asto firmly hold the hop- `per in place, and the gate in its closed position, while the cable 21 is slightly slacked. Secured to the ends of the bar 2O are plungers 24 entering pipes 25 through stuffing boxes not shown, andthese pipes 25 are connected through pipes 26 through a valve 27 with a standpipe 28, the pipes 25 and 26 being filled with suitable fluid to provide an hydraulic check for the upward movement of the bar 20. The position of the hopper, when it is being filled, is high enough so that the top of the truck-cab may pass beneath it, and after the cab has passed beneath it, it may be tipped to discharge the contents into the truck, and this is done by opening the valve 27, allowing the iiuid to rise in the standpipe 28 and permit the bar to rise as the hopper tilts forward. As the hopper tilts forward, as shown in Fig. 4 of the drawings, owing to its inclination, the cable 18 becomes slack, so as to allow the gate 16 to swing open to permit the contents of the hopper to be discharged. At this time the slack on the cable 21 is taken up, so that the hopper is supported by that cable. The counter-balancing weight is slightly heavier than the weight of the empty hopper, so that, when the hopper is discharged, it is brought back into the lling position by the downward movement of the bar 20 by `the counter-balancing weights, thefluid in theV standpipe 28 following down as the plungers 24 retire, and when thevv hopper is back in the loading position, the valve 27 is closed until it isrdesired to again empty the hopper.
I thus provide, in a very simple way, a batch-measuring hopper adapted to discharge predetermined quantities of material intol separate compartments of' a truck, and so 'arrange the hopper that it may be discharged and returned to its loading position by the operation of fa single valve.
I claim: Y. 1. A. batch-measuring hopper, comprising a hopper having a pluralityV of compart-k ments, each divided `into chambers, said chambers having a common dischargemouth,- a'hinged gate adapted to close said mouths, said hopper pivotally mounted in a frame, cables connected with said hopper and with said gate', a counter-balanced bar with which said `cables are connected, and yhydraulic checks for the upward movement ofv the saidk bar.V
2. A batch-measuring hopper, comprising a plurality of compartments, each including two chambers, the chambers of each compartment having a common discharge mouth, agate hinged'to the hopper and adaptedV to close lsaid mouth, said hopper provided atl its ends 'with arms 'extending below its lower edge,a shaft on. which said arms are mounted, a vertically-movable bar,
cables extending from said gate to said bar vand from the ends of said hopper to said bar, said bar provided at opposite ends with plungers, pipes into which. said plungersV extend, said pipes Vconnected with a stand pipe, and'a valve therein controlling Vthe ,passage of fluid through said pipes.
v3. A batch-measuring hopper, comprising a plurality of compartments, each divided into two chambers, each pair of chambers opening into a common mouth, a gate hinged at its upper edge to said hopper and adapted to close said mouths, said hopper pivotally mounted and adapted to tip forward and downward, a counter-balanced bar, cables extending from the ends of the gates to said bar and from the sides of the hopper to said bar, said cables being so proportioned in vlength that when the hopper is in its loading GEORGE H.
