SAND-HANDLING APPARATUS.
Specification of Letters Patent.
Patented Feb. 9, 1915.
Application filed July 28, 1914. Serial No. 858,638.
To m1. whom it may concern Be it known that I, HARRY l. MACDONALD, a citizen of the United States, residing at Montclair. in the county of Essex and State of New Jersey. have invented certain new and useful Improvements in Sand-Handling Apparatus, of which the following is a specification.
This invention relates to ap aratus for handling sand and similar granu or material, but it has particular reference to devices for handling and treating sand preparatory for use in metal toundin u operations, especially in foundries where t e sand is stored over 'head. In general. m y invention has for its primary object the provision of an improved apparatus -of simple and economical -construction hereby sand may he transferred and prepared for immediate use with great rapidity and with a minimum numb r of operations. Another object of my invention resides in the provision of an improved appuratus for feeding and riddling sand into a ilusl: or similar receptacle with QYGHIIGSS and uniformity. and my invention also wnte uplates the provision, in conjunction with the foregoing. of improued means for guid ing or directing the sand discharged from the riddle into the flask.
The foregoing. together with such other objects as may hereinafter appear or are incident to my invention. l attain by means of a construction hirh I have illustrated in referred torn: in the accompanying drewin s. wherein igure 1 is a vertical section'through my improved apparatus; Fig. 2 and F i 3 are sections taken on the lines I1-- I and lll -l ll respectively of Figure 1; Fig. 4 is a plan view of detail part of my invention; and Fig. 5 is plan view of a modification of my invention.
The general arrangement of my improred apparatus is shown in Fig. 1 f om inspection oi which it will l seen that I employ a sand storage means. such. for example. as the hopper .l. inunciliutely henculh which is :i ridillingz' d w'irrli. Beneath the. riddling de ic i: o :g i lr chrte l" which directs the coins (4' tinsand so that it falls into the flask l).
The riddle B may be of any suitable ty e, but it preferably should be in the form 0?:1. trough-like frame 7 in the bottom of which is secured a foraminous member," such as a screen 8. the riddle being positioned so as to surround the discharge end 9 of the hopper, with the screen closely adjacent thereto. The riddle is reciprocated by means of the connecting rod 10 operated by the crank shaft 11 of the motor 12. In orderto hol the main portion of the sand out of direct contact with the screen 8, I provide a plurality of bars 13 which extend across the discharge opening in the hopper, as shown and described in my 00- vending application Serial No. 812.052, filed une 1, 1914.
The guide chute is substantially rectangular in cross section and its walls 14 flare outwardly at the top so as to catch an sand that is carried past the edges of the opper by the riddle. Located Within and extending transversely of'the chute are a. plurality of guide or deflecting plates 15. which deflect the sand discharged from the riddle so that it falls substantially straight down. The function of these plates will be clear when it is seen that the reciprocating riddle. which moves with considerable velocitynprojects the particles of sand dischar ed at an angle to the vertical, and in the a sence of such deflecting means the sand would be scattered over a wide area. As indicated in Fig. 3, the plates lo'niay be adjustably supported in the walls of the chute by means 01' the trunnions 16 and nuts 17. By loosening the nuts the angle of the plates may be varied so as to deflect greater quantities of sand to a given portion of the flask, which is of 0011? siderable value in some classes of work.
In order to catch any stray sand, I pro vide a funnel shaped member E which is placed upon the top of the flask D in the manner indicated in Fig. l. -I prefer to place a formninous member. such as a screen 18. above the member E, the purpose of which will appear from the following: In some cases the sand discharged from the overhead storage means will have consider able distance to fall, and it Will therefore attain a velocity Which Will cause It to 1mpact with a force sullicient to pack or ram reciprocates so that it falls Within a limited area, the discharge end of the chute being located a substantial distance. o erhead relati ve to the point of use whereby unobstructed access is bad to the sand atthe point of T. A sand handling apparatus comprising in combination an overhead sand storage means having a discharge opening from which the sand falls a substantial distance to the point of use, a substantially horizontally reciprocating riddle adjacent thereto, and means adjacent to the riddle for deflecting the sand discharged by the riddle so that it falls substantially vertically within a limited area.
8. A sand handling apparatus comprising in combination a sand storage means having a discharge opening, a substantially horizontally reciprocating riddl'e, and means for deflecting the sand discharged by the riddle so that it falls substantially vertically within a limited area comprising a chute provided with a plurality of substantially vertical baflles.

A sand handling apparatus for foundries comprising in combination a substantialiy horizontally reciprocating riddle located a substantial distance above the foundry floor so that the sand falls a substantial distance to the point of use, and means located therebeneath for deflecting the sand discharged by the riddle so that it falls substantially vertically Within a limited area, the discharge end of said means being located a substantial distance above the point of use.
10. A sand handling apparatus comprising in combination a substantially horizontally recipi-(xtating riddle, and means located therebeneath for deflecting the sand discharged by the riddle so that it falls substantialiy vertically within a limited area, comprising a chute having an adjustable bafl'le Wall.

A sand handling apparatus comprising in combination a substantially horizonally reciprocating riddle, and'means located thercbeneath for deflecting the sand discharged by the riddle so that it falls substantially vertically within a limited area. and means located in the path of the falling sand to break the fall of the sand and prevent packing of the sand.
12. A sand-handling apparatuscomprising in combination a flask, a sand feed therefor located above the flask, and an interposed foraminous member adapted to break the fall of the sand, said member leaving a portion of the flask uncovered, whereby the sand in said portion will pack to a harder degree than the sand in other p rtions of the flask.
13. A. sand-handling apparatus comprising in combination a flask, a sand feed therefor located above the flask, and means in the path of the sand adapted to break the fall of portions thereof whereby in parts of the flask the sand will be packed harder than in others.
14. In apparatus of the class described, the combination of a flask to be filled with sand. and means above the flask for directing the course of the sand whereby the sand packs itself harder in some portions of the flask than in others.
15. In apparatus of the class described, the combination of a flask to be filled with sand, and means in the path of the sand adapted to impede the progress of portions thereof whereby the sand in parts of the flask is packed harder than in other parts.
