.MATERIAL-HANDLING APPARATUS.

Application filed March a1, 1923. Serial No. 629,070.

To all whom it may concern:

Be 1t known that we, EDWIN F. JONES and JOHN A. AULD, citizens of the United States, residing atErie, in the county of Erie and .State of Pennsylvania, have invented new and useful Improvements in Material-Handling Apparatus, of, which the following is a specification.

This apparatus is particularly designed for measuring materials, such as road-making materials where an accurate amount is required. The desirable way of measuring such material is by filling the measuring bin with slightly more than the exact amount and striking off the excess. Heretofore this excess as it was struck olf has been allowed to fall and accumulating has required handling. With the present device the material struck off by a strike-01f blade is caught and delivered-to the measuring.

bin so that there is no after-handling or dilli'culty encountered in the operating or clogging of the strike off device. preferred form the striking off is accomplished with a movable bin operatingunder a strike otlj blade. Details and features of the invention will appear from the specification and claims. The invention is illustrated in the accompanying drawings as follows Fig. 1 shows a side elevation.

actuating mechanism 14. The car is moved 1 marks the supporting posts, and 2 and 3 storage bins carried by these posts and the usual frames. These storage bins are designed to hold different materials such as gravel and crushed stone and have the discharge openings 4 and 5 respectively. A car 6 mounted on wheels 7. is arranged under the storage bins, the wheels operating on tracks 8- so that these cars may be moved to effectjthe striking ofi' operation and carry the material if desired to a more satisfactory or convenient osition to dump into the trucks. Measuring bins 9 and 10 are usually arranged in pairs of suitable size. These are closed at the bottom-by doors 11 hinged at 12, these doors being connected or operated by a link 13 operated from a. common by a cable 15 running around pulleys 16 and 17, the pulleys 17 being carried by a shaft 18. A gear 19 is mounted on the shaft 18 and operates from a pinion20, the pmion In the being operated by means of a crank 21. It

.will be understood that there are a number 91 bins and these are adapted to'dump what 18 commonly called a batch into different compartments of the vehicle which is to receive them.

The openings 4.- .md 5 over each of the measuring bins 9 and 10 are closed by a:

the bins at 28.so that the catcher pockets are arranged at the sides of these bins. In

Fig. 3 the one attheleft is shown in a tilting position and the one at the right in. the

lowered position, the position it assumes in 5 receiving the excess material as it is struck off. by the strike olf blade. Rollers 29 are mounted on the arms 27 and inclined bars 30 are arranged in the path of the rollers 29 so that as the bins are moved to a posi== tion under the openings 4 or 5 the pocket 26 of that bin is tilted as shown at the left 7 i of Fig. 3 thus dumping the material which was received by it in the preceding strike ofi' operation into the bin previous to the deposit of the new quantity of material from the storage bin. The pocket-then remains in the inclined position until the filling of the measuring bin when the car is again moved to the right as shown in Fig. 3 and as the excess is struck oil it is carried into this pocket and held there until the succeeding operation. The excess material. at the right will, when the bin 10 is carried under the opening 5, be tilted thus emptying any material in it into the bin 10 previous to the filling from the opening 5. In this way there is no accumulation of this excess and there is a free and accurate action of the strike off blade; means for moving the bin and blade relatively to strike off excess material; and atilting catcher actuated with the relative movement of the blade and bin to return the overflow to the bin.

3. In a material handling apparatus, the combination of a measuring bin; a strike off mechanism; a tilting pocket at the side of the bin adapted to catch excess material; and means for actuating the pocket 'to return the same to the bin.

t. In a material handling apparatus, the combination of a movable measuring bin; a strike ofl' blade operating over the bin; a tilting catcher arranged at the side of the set our hands.
