JACOB NESSLY PORTER, OF KENILWORTH, WEST VIRGINIA, ASSIGNOR TOTHE GLOBE BRICK COMPANY, OF EAST LIVERPOOL, OHIO, .A. CORPORATION OF WEST VIRGINIA BRICK MACHINE Application filed December 9, 1929. Serial No. 412,829.

This invention relates to a brick press, more particularly to an attachment therefor actuated by the pressing mechanism for feeding the bricks away from the pressing position.

In machines for pressing bricks, of which I have knowledge, each brick after it is molded, shaped or pressed, is fed from-the pressing position forwardly by a reciprocat ing member of the machine, and such brick in turn engages and feeds forwardly the previously formed brick or bricks depending upon the length of the feed table or the speed at which the delivered bricks are removed therefrom. Due to the forcerequired to move or feed the bricks along the table, contact of one brick with another frequently results in damaging their surfaces or marginal edge portions. Also, portions of the brick dust and the brick material, which accumulate on the feed table collects in front ofeach brick as it is pushed forward by the reciprocating member into engagement with the preceding brick, with the result that this collected material is compressed between such brick and the next forward brick as both bricks feed forwardly. This compressed dust or material usually adheres to one, brick or the other or usually result in seriously damaging them as the projections when removed invariably carry with them portions of the brick body,

this being particularly true since the material adheres to the surfaces of the bricks near and along their lower edges and the edges break away with the projections relatively easy.

One object of the invention is to provide an improved attachment for a brick press ca pable of feeding bricks forwardly, after molding or shaping, in spaced relation,

whereby contact of the bricksone with another While being fed forward and collect-- ing and compression of free material between the bricks with resulting adhesion thereof to Another object of the invention is to provide in a brick press an improved supplementary feeding device arranged to co-operate with the main delivery or feed member of the press to maintain the bricks during feeding in spaced relation.

Another object of the invention is to provide an improved auxiliary feeding attachment fora brick press correlated with the delivery memberthereof and capable of adjustment for feeding bricks of different sizes.

A further object of the invention is to provide an auxiliary feeding device for a brick press which is relatively simple in construction and readily attached to the press'mechanism for feeding bricks of varying sizes.

Other objects of the invention will be apparent to those skilled in the art to which my invention relates from the following description taken in connection with the accompanying drawings,.wherein Fig. 1 is'a sectional View of a brick press embodying my invention, the pressing mechanism being shown'in the position it occupies when pressing the material into a brick.

Fig. 6 is a section ofthe line 6-6 of Fig. 4. Fig. 7 is a perspective view of the auxiliary feeding device. I My invention is applicable to brick making adapted in its forward movement to move machines having a reciprocatable member 7 each brick or series of bricks away from the shaping, pressing or molding position. One such machine is shown in the drawings and may be briefly described as follows:

1 indicates a suitable support for a frame 2.

The frame 2 comprises spaced side members 7 20 (one only being shown) hollow members 26, 2b, to which the side and transverse 7 members 2a are rigidly connected. The transverse members 25, 2?) rest on the support 1. Each side member 2a is shaped along its front portion to form an inner end wall 3, which co-operates with an outer removable end wall 4 to form a vertical guide 5, the guide on one side member 2a together with a similar guide on the other side member slidably supporting pairs of upper and lower shoes 6, 7, the purpose of which will later ap pear. ed in bearings 9 provided 011 the side members 2a, the shaft having on one end a pulley 8a or other device to receive power from a suitable driving means. The pulley 864 may be connected to and disconnected from the shaft 8 by means of a suitable clutch 8. At its other 'end the shaft 8 is drivingly connected through gearing (not shown) with a countershaft 10, supported similarly to the shaft 8, and the counter-shaft 10 in turn carries a pinion 11 meshing with a gear 12. The gear 12 is fixed to a shaft 13 suitably mounted in the adjacent side member 2a. On its inner side but outwardly of the side member 2a, the gear 12 carries a casting shaped to form a continuous camway 14:, the purpose of which Will later appear. The shaft 13 at its inner end is provided witha crank 15 to the end of which is pivotally con nected the inner end of a combined thrust and rocking member 16. The outer end of the member 16 is pivotally connected to a pin 17, which pivotal ly connects the inner ends of a plurality of toggles each comprising links 1819 (one toggle only being shown). The outer ends of the links 1819 are pivotally mounted on cross shafts 20, 21, respectively supported rotatively at their opposite ends in the pairs of shoes 6, 7, respectively.

The combined thrust and rocking member 16 is adapted to roll on a roller 22 loosely mounted on a stud shaft carried by the adjacent side member 2a, this roller being so related to the shaft 13 that the crank 15 in co-,

operation therewith causes the outer end of the member 16 to traverse a predetermined cycle in each revolution of the crank 15, the effect of which through the toggles is to move the shoes upwardly or downwardly and relative to each other to produce in each such cycle a brick or seriesof bricks in the manner pressers 24, 25, one pairfor each opening,

connected to and operated by the shoes 6, 7,

to press the bricks. The forward portion of the base a co-operates with a shelf 26 to form a feed table 26 for the bricks A and the inner portion of the base and a cross plate 27, suitably supported by the side members .8 indicates a main drive shaft mount 2a, provide a surface on which a member 28 reciprocates, this member being guided in its movements by suitable guides 29 at the opposite side edges of the cross plate 27. By preference the base 20a and cross plate 27 are covered with a steel plate 27a to provide a plane, jointless surface for the member 28 to slide on. The reciprocating member 28 is shaped to form four pockets 30 and a gate 31 rearward thereof; and in the rearmost position of the member 28 (see Fig. 2) these pockets register with the delivery openings of a supply hopper 32 to receive suitable brick material B therefrom and in its foremost position these pockets register with the die openings 23 and permit the brick material B to flow into the latter (see Fig. In this latter position, the gate 31 moves below the hopper openings to close them. The reciprocating member 28 has a movement slightly longer than the length of the bricks measured in the direction in which the member moves and is operated in timed relation to the movements of the pressers 24, 25, by the following elements: 33 indicates a pitman connecting the rear portion of the member 28 with the free end of an arm 34:. The arm 34% is fixed to one end of a rock shaft 35 suitably mounted in the adjacent side member 2a; The other end of the shaft 35 carries a crank 36 having a stud 36a which retatably supports a roller 37 adapted to ride in the camway 14, the latter being shaped to effect reciprocating movements and rests therebetween for the member 28.

The presser 24: is carried by a base portion 38 which is guided in its up and down movements by opposing guide walls 39 provided interiorly of the transverse member 2?). The opposite ends of the base portion are connected to the lower ends of a pair of plungers 40 connected at their upper ends to the opposite ends of the shaft 20 outwardly of the shoes 6, the plungers serving to support the base portion 38 and presser 24 and to move the latter upwardly and downwardly with the shoes. The presser 25 extends between and is connected to the shoes 7 and moves therewith upwardly and d wnwardly.

' In the cycle of movements of the outer end of the member 16 transmitted through the toggles to the shoes 6, 7, the pressers 2 25, are separated as shown in Fig. 3, at which time the reciprocating member is in its forwardmost. position and registering with the dies to fill the latter with the brick forming material B. In the movement of the reciprocating member 28 to this position its front wall 2860 has engaged and moved the previously formed bricks A forwardly on the table 26; next, the member 28 moves rearwardly and the presser-s are moved into pressing position in the dies as shown in Fig, 1; next, the pressures 24-, 25, move upwardly, the presser 292 carrying the pressed bricks ill;

upwardly to the plane of the table 26 (see Fig. 2) the movement of the presser 25 being accelerated relative to that of the presser 24; and next, the reciprocating member 28 moves forward to move the pressed bricks forwardly and to refill the dies.

41 indicates an auxiliary feeder, arranged to move with the reciprocating member but in spaced relation therefrom. The feeder may comprise a single device or a plurality of devices disposed in front of the reciprocating member 28 and spaced therefrom a distance greater than the length of a brick but less than the distance between it and the rear surfaces of the bricks when in the position to which they are moved by the member 28. In the preferred form of construction I provide two feeders 42, 42, each common to two bricks and connect each thereof by an arm 48 to the reciprocating member 28. The arm 43 may be of sectional form having overlapping portions clamped together in adjusted relation by one or more bolts 44 extending through elongated slots 44a formed in the sections so that the feeder 42 carried at the outer end of the outer section maybe adjusted different distances from the reciprocating member 28 according to the length of the bricks A. The inner end of the inner section is preferably bent downwardly as shown at 45 and formed with an elongated slot 45a, bolts 46 extending through the slot to adjustably secure the end 45 to the front wall 28a. The adjustable connection permits the arm to be raised or lowered and thus adjust, the-feeder to bricks of difi'erent heights. Each arm end 45 is connected to the front wall 28a midway between adjoining bricks A and the adjacent arm extends forward therefrom in the plane of the space between the bricks. The adjacent feeder 42 is hingedly connected to the outer end of the arm and depends therefrom and extends to either side of the arm so as to engage two of the previously formed bricks in the next forward movement of the reciprocating member 28. (See Figs. 2, 4 and 6.)

As this latter movement takes place, the previously formed brlcks will be moved forwardly, but maintained out ofcontact with the bricks being simultaneously moved forwardly by the reciprocating member 28, as shown in Fig. 3. By hinging the feeder 42 on the arm, its lower end is free to swing outwardly, so that, in its rearward movement it will ride the bricks moved forwardly by the reciprocating member (see Fig. 5) to a position rearwardly thereof (see Fig. 2) ready to engage them in its next forward movement. The free end of the outer arm section may be bent downwardly, as shown at 47 to form an From the foregoing description it will be noted that each series of bricks after being formed are fed forwardly from the forming or shaping position by the reciprocating memher and in the next movementthereof the auxlliary feeder moves them outwardly on the table while the next or succeeding series of bricks is being moved by the reciprocating member. By positioning the feeder in spaced relation to the reciprocating member as herein described, the bricks fed by it are maintained in separated relation to those being fed by the reciprocating with the result that the bricks cannot contact one with another and any free material which collects in front of them cannotbe compressed between and against their front and rear surfaces.

To those skilled in the art to which my in vention relates many changes in construction and widely differing'embodiments and applications of the invention will suggest themselves without departing from the spirit and scope thereof. My disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting.
