specification of Letters Patent. Patented June 10, 1919 Application med June 4, l1918. Serial No. 238,140.

To all whom z't may concern.'

Be it known that I, IVAN C. FREY, a citizen of the United States, residing at York, in theA county of York and State of Pennsylvania, haveY invented certain Improvements in Brick-Mold-Handling Apparatus, of which the following is a specification.

My inventionl is an improved apparatus for handling brick molds, and in its preferred form it comprises synchronously operating divergently moving conveyers for separating a mold from its contents, means for moving the emptied moldto a sander by which it is coated with a regulated quantity of sand, turning the sanded mold to the upright or filling position, and automatically returning the mold to the lling chamber of a brick machine. It is designed primarily to eliminate much of the hand labor now necessary; to reduce the breakage commonly occurring in the removal of `bric s from the molds; to avoid damage to the molds resulting from usual modes of sanding; and to provide a regular supply of evenly sanded molds.

The characteristic features and advantages of my invention will more fully appear from the following description and the accompanying drawings in illustration thereof. v

In the drawings, Figure 1 is a part sectional plan view of apparatus embodying my invention; Fig. 2 is a side elevation of the mold emptying mechanism; Fig. 2A is a fragmentary view illustrating the placing of a filled mold on the emptying mechanism: Fig. 3 is an end view of the apparatus; and

. Fig. 4 is a broken side elevation showing the mechanism for sanding the brick molds and turning them from inverted toA filling position. Y

As illustrated in the drawings, my invention is embodied in a machine comprising/a frame consisting of

end housings

1 and 2 connected by side beams 3. A pair of inclined stringers or tracks 4 extends from the housing 1 to the uprights 2 of the housing 2, 'and a second pair of stringers or tracks 5 extends from the housing l to the uprights 2 of the housing 2; the pairs of tracks being diagonally disposed relatively to one another and preferably formed of angle irons.

A shaft 6, journaled in bearings on the 6a which engage the sprocket chains 8 movable over the .tracks 4; and a shaft 9, journaled 1n bearings 10 on the housing 2, has fixed thereon sprocket wheels 9b which engage Athe sprocket chains 11 movable over shaft 15, the latter being journaled in bearings 1'6 of the housing and driven through the sprocket wheel 17 from a source of power, as, for example, lthe driving shaft of the brick making machine; whereby the

sprocket wheels

12a and 12b are revolved and the chains 8 and 111 are drawnupwardly over the tracks 4 and 5.

Hangers 18, depending from the side beams 3, have bearings 19in which is journaled a shaft 20 having fixed thereon the sprocket wheels 20a and 20b over which the

respective sprocket chains

8 and 11 pass to the respective sprocket wheels 21a and 21b fixed on the shaft 22 journaled in bearings 23 on the housing 1.

A counterweighted dumping table 24 is lourna'led in bearing brackets 1 lon the housing 1 and is adapted to receive pallets A on which are deposited filled brick molds B transferred thereto, either manually or mechanically, from the conventional brick machine C.

The weight of a lled mold rocks the table 24 to the position indicated in Figs. 2A, and permits the pallet beneath the mold to be engaged by the chains 8 and the wider mold to be engaged by the chains 11 and heid in substantially horizontal positionuntil it has cleared the apex of the sprocket wheels 9", when it drops down te the cross tracks 27 ofthe housing 2.

The mold is moved over the tracks 27 in 1 the direction of its length by its engagement and lifted clearv with a sprocket chain 28; the chain being engaed by the sprocket Wheel 29 fixed on the s aft 29 (journaled between beams 30,) by the sprocket Wheel 3l (journaled on a bracket 32 on the housing 2), and by the sprocket wheel 33a fixed on the shaft 33 (journaled in bearings 34 on the housing 2). rlhe shaft 83 has fixed thereon a pulley 35 connected by a twisted belt 36 with a pulley 37 on the shaft l5 to move forward the sprocket chain 28. f

The chain 28 delivers the mold to inclined rollers 38 (journaled in bearings 39) down which it runs to rollers 40 journaled in a table 4l, the latter being pivotally connected with the, housing 42 and eounterbalanced by weights 41a.

The housing 42 and a housing 43 provide supports Jfor a pair of stringers or tracks 44e over which pass a pair of sprocket chains 45. These chains are engaged by sprocket wheels 46a (fixed on a shaft 46 journaled in bearings t7 on the housing 42) and by the sprocket wheels 48a (fixed on a shaft 48 journaled in bearings 49 on the housing The shaft 43 has fixed thereon a sprocket wheel 48h connected through the chain 50 with a source of power. as the driving shaft of the brick machine. whereby a brick mold deposited on the chains 45 b v the tiltimgr of the table 41 is carried to a sander 5l.

The sander comprises an upper compartment 51 and a lower compartment 5l". l shatt 52, journaled in spiders 53 on the. walls of the compartment 5F, has '.liXcd thereon the sprocket wheel 52". driven bv aehain 52 trom a sprocket wheel 48C on the shaft 48, and the oppositely inclined screws 54 and 54. the revolution ot which feeds a regulated amount of sand 4through the apertures 55 in the walls of the compartment.

The sand thus ted is conveyed b v tunnels 56 to the, compartment 51b Where it is discharged on top ot the. blades 57 fixed on the shaft 5'?. the latter being iournaled in spiders .i8 and revolved (bv the pulley 59 connected b v a belt fi() with the driving shaft ot the brick machine) to throw the sand upwardly into the inverted mold as it is carried tliereover bv tybe chains 4 5.

Stops (li on the tracks 44 engage the mold upon its emergeneevirom the sander and prevent its further movement b v the chains iii. inverting arms GQ. hn'ed on and revolved by the shaft 4t2. engage the bottom ot the mold and brackets 69; on the arms engage the iront of the mold. which bv the revolution ot the arms is lifted clear oii'the chains and stops. turned about the anis oie lthe shaft 4R and deposited in upright. or tillingi position on inclined rollers 6?, iournaled in the bearings G4. .d belt (i5. supported b v rollers (ld. eXtends iirom the rollers 62 through the rcceivin;T chamber ot the briclr machine (l and is moved. to carry into such chamber a mold nacen?? Yby means of a pinion '67 fixed on the inner roller 66*1 and engaged by the pinion 68 on the shaft 68, the latter being driven from a suitable source of power, as the driving shaft of the brick machine.

In operation. a pallet A is placed on the dumping table 24 and a filled mold from the brick machine placed thereon with its tace against the pallet. The weight of the tilled mold tilts the table so that the pallet is engaged by the conveyer chains 8 and the Wider mold is engaged by the conveyer chainsl. IThe conveyor chains are simultaneously moved' forward in divergent planes. as described. and the, mold l' litted from the pallet and bricks without injury thereto. The emptied mold is discharged in horizontal position onto the tracks 27 over which it is moved b v the eonveyer chains 28 to the

rolls

38 and 40. The, weight of the mold depresses the table il to permit the engagement ot the mold hv the conve'ver chains 45. b v which it is carried through the sander 51 and evenly. sanded with a regulated amount ot sand. immediately on leavingr the sander. the mold is turned to the upright or filling positionfbv means oi the. in-

` vertina arms 62. and thence carried over the rolls 63 and belt 65 to the receiving chamber oi the conventional briclr machine fl in -which it is again `lilled and the described operations repeated.
