BRICK-MAKING MACHINE.

.Applioation filed July 5,

This invention relates to brick making ma chines and more particularly to the improved means for carrying off. the molds with the bricks therein, the object of the invention being to provide exceedingly simple and highly eflicient mechanism for removing the bricks from the molds and directing them to the driers and then returning the molds to the brick making machine and sending said molds on the return passage.

With these various objects in view the in-. vention consists in the novel features of con struction and in the manner of combining or arranging the same in certain cooperative relations, all of which will be fully described hereinafter and pointed out inthe claims.

In the drawings forming a part of this specification Fig. 1 is a side elevation showing one-half of my improvedapparatus, the actuating means being omitted; Fig. 2 is a similar View of the forward half of the apparatus; Fig 3 is an enlarged fragmentary side elevation of one portion of the device; Fig. 4 is a plan view of the partsshown in Fig. 3 Fig. 5 is a section on the line 5-5 of Fig. 4 showing the partsin one position; Fig. 6 is a view similar to Fig. 5 showing the parts in another position; Fig. 7 is a section on the line 77 of Fig. 3; Fig. 8 is a detail view of the means for jarring the filled mold; Fig. 9 is a detail perspective View of one end of the mold, a pallet being shown thereon in dotand-dash lines; Fig. 10 is a side elevation of one-half of the mold receiving and retaining mechanism; Fig. .11 is a vertical sectional view taken on the line 11-11 of Fig. 10; and Fig. 12 is a view of thesame part showing the position assumed by the spring actuated retaining members during the upward passage of the mold; and Fig. 13 is a detail perspective view of the arm carrying such spring actuated retaining device.

Referring to the drawing 10 indicates in outline the brick making machine which ordinarily would embody a mold 11 which is placed beneath the die of the brick machine in a manner more fully described hereinafter. The mold previous to being forced beneath the die is held in a horizontal position by means ofthe mold retaining device 12 andis pushed beneath the die by means of any suit 1922. Serial No. 573,034.

able form of pusher 13. As one mold is pushed beneath the die the mold which has just been filled is pushed upon the table 14 and into a jarring device which comprises a transversely reciprocal bar 15 (see Fig. 8) having upwardly projecting arms 16 at each end to which hammers 17 are adjustable connected, these hammers being alternately brought into engagement with the ends of the mold as the bar is reciprocated through the medium of the rod 18 actuated from any suitable device. The rod15 slides in a suitable guideway 19 whichconstitutes a part of the table 14 upon which the mold rests. After 5 the mold has been knocked or jarred it is pushed along forwardly by the next succeeding mold and the table 14 may be of any suit- 1 able length capable of accommodating any desired number of filled molds. After the tilled mold has ben jarred as previously described a pallet 20 is laid upon the top of the mold. At the forward end of the table 14 I arrange a mold inverting and ejecting device comprising a revolub-le bodyQl mounted upon trunnions or pivots 22 and one of which is connected to any suitable rotating mechanism 22 and this revoluble body 21 is made either of cast metal or built up as desired to provide oppositely disposed mold receiving chambers 30 23 separated by a central wall or partition 24 in which works a plurality of ejector rods 25 having heads 26 at the opposite ends thereof. The tilled and palleted mold is pushed into the rear chamber 23 and at the proper 35 interval the body 21 is given a half turn which completely inverts the mold as shown in Fig. 1 and then at the next movement of the machine this filled and palleted mold 11 is ejected from the body 2-1 by the next succeed.- ing filled and palleted mold coming in con.- tact with the ejectors 25, these ejectors being pushed forwardly and in doing so force the filled and palleted mold from the opposite chamber of body 21 and dischargethe same upon a vertically movable table 27 adjacent the forward end of the mold inverting and ejecting mechanism.

When the table 27 is lowered by means to be described hereinafter the mold is held on guideways 28 extending. forwardly from the table 14 and the pallet and the bricks thereon will leave the mold readily, due to jarring previously received, and be carried clownwardly until the pallet and bricks are deposited upon a pair of endless chains 29 which travel around

sprockets

30 and 31 on

shafts

32 and 33. This is shown in Figs. 5 and 6. The chains 29 are placed, one on each side of the table 27 as is shown in Figs. 4 and 7. i

The pallets 20 are carried forwardly on the chain 29, to a lateral carrier 34 by meansof which the bricks are conveyed to a drier or other suitable device.

The table 27 has two U shaped members 35 attached to the under side near the ends thereof, andthe members 35 each have a stud 36 projecting downwardly from the closed end thereof and extending through holes in a horizontal cross piece 37 which has its vertical ends38 secured to the mold guides 28. A cross bar 39, also extending between the guides 28, bears against the inner sides of one of the vertical legs 35" of the U- shaped member 35 and the inner face of the other legs 35 bears against the shaft 32. This construction holds the table 527 horizontal at all times and guides it in its up and down movement.

Each leg 35 of the members 35 has a lug 40 projecting rearwardly therefrom, which are adapted to be engaged by lingers 41 on a shaft 42. This shaft 42 is oscillated by cams .43, on opposite ends of the shaft 32, which engage fingers 44 on the ends of the shaft 42, and as the shaft is oscillated the table 27 will be moved up and down by the fingers 41. The cam 43 is so constructed that the table 'will dwell for a short period at each end of its movement; at the upper end to receive a mold from the inverting mechanism and at the lower end to allow the chains 29 to carry the loaded pallet from above the table.

Each succeeding mold delivered from the invertin mechanism will force the preceding molds afong the guide ways 28 and onto the pair of spaced parallel endless conveyor chains 45 traveling around sprockets 46 and y 47 on shaft 48 and 49.

The chain 45 will deliver the molds onto a pair offingers 50 which are loosely mounted on a shaft 51. The fingers have rearwardly projecting extensions 52 on which are mounted weights 53. The weight of the mold will over balance the weights 53 and the fingers 50 will drop down'to the position shown in dotted lines in Fig. 2 and will deposit the mold onto an endless chain 55.

Stops 54 limit themovement of the fingers in either direction.

The chains 55 travel rearwardly around sprockets 56 mounted on the shaft 57 and this upper flight of the chain passes over the open top of a sanding device 56 which may be of any suitable construction capable of throwing the sand upwardly into the inverted mold. At the rear end this endless chain 55 passes around a sprocket 57 mounted upon the shaft 58 and directed to the rear of this endless chain I arrange a mold reversing device comprising a revoluble body 59 having oppositely disposed mold receiving chambers 60 which are separated by a central wall 61 through which work the ejector rods 62 having flat heads 63.

In practice I propose to so arrange the parts and so time the mechanism that a plurality of emptied and inverted molds will be caused to contact end to end with each other and extend across the top of the sanding device so that during the operation of said sanding device the inverted molds will practically constitute the top of the same and none of the sand will be wasted but all of it which is thrown upwardly will come into contact with the inverted molds. The rearmost inverted and sanded mold is forced into the forward chamber of the mold reversing device and by said device is reversed and then ejected upon a horizontal endless carrier chain 64 and at:

the end of this chain the sanded mold is picked up by the lifting arms 65 and carried upon the mold receiving and retaining device which constitutes a part of the invention disclosed in 1n application filed May 3, 1922, now Patent 0. 1,529,453, and comprises a pair of arms 66 mounted upon a horizontal rod 67 and these arms are substantially in the shape of an inverted U and between the depending portions thereof there 'is pivoted the spring actuated mold retaining devices consisting of the inwardly projecting fingers 68 preferably made in pairs and united by a bar 69, these fingers being pivoted upon the shaft 70 and the springs 71 connect the arms 66 to the connecting pins 7 2 extendin between the parallel finger portions 68. These fingers are each formed with an inclined lower side 68 against which the ends of the mold contact as said mold is lifted upwardly and the fingers being pivoted will be forced outwardly and after the mold has been moved up a sufficient distance to clear the fingers the springs 71 will throw them back to their normal positions as shown in Figs. 10 and 11 and rest beneath the molds so as to properly support the same, the return movement of these spring actuated fingers being limited b the stops 73 which contact with the depenc ing portions of the arms 66. As previously stated, while the mold is held in this manner, it is pushed forwardly b the pusher 13 beneath the die of the bricli machine ready to receive the charge of clay therein.

It will thus be seen that I provide a simple and highly efiicient apparatus for conveying away the filled molds, jarrin the same previous to receiving the pallet, tl ieninverting the filled and palleted mold, separating the mold from the bricks and returning said molds properly sanded and reversed ready to be picked up and placed in position to receive another charge of clay.

Having thus described my invention, what I claim is:
