To ctZZ whom it may concern: 7

Be it known that 1, ROBERT F. RoBrsoN, of Kansas City, in the county of \Vyandotte and State of Kansas, have invented certain new useful Improvements in Brick-Making Machines, of which the following is a specification.

The improved machine is illustrated in the accompanying drawings, in which Figure 1 is a view of one side of the machine. Fig. 2 is a view of the opposite side thereof. Fig. 3 is a plan view with the feed-hopperremoved. Fig. 4c is a longitudinal vertical section. Fig. 5 is alongitudinal transverse section in a plane indicated by the line 5 5 in Fig. 3, and Fig. 6 is a detailed view of the engaging and disengaging gearing.

The machine comprises in its general c011- struction a supporting frame-work, A, having a series of molding-compartments,B B, side by side at one end of the machine, a feedhopper, C, communicating with all of the moldingcompartments and above the same, a series of horizontally-reciprocating pressers, D D, one for each of said molding-compartments, a vertically-reciprocating cover, E, which closes all of the molding-compartments during the pressing of the bricks, a series of vertically-reciprocating followers, F F, which lift the finished bricks from the several molding-compartments, a receivingtable, G, fixed to the frame-work upon which the finished bricks are discharged, a series of swinging fingers, H H, which push the finished bricks from the followers onto the receiving-table, and mechanism for actuating the several movable parts and insuring their proper action. I

In the operation of the machine a complete brick is made in each molding-compartment at each sequence of operations, and the machine may be made with any number of moldin g-compartments, with their accessory parts, depending upon the business of the establishment running the machine.

In the accompanying drawings the machine is shown with only two molding compartments; but this is for the purpose of illustration only, since the invention is not limited to any particular number of the compartments.

The reciprocation of the pressers D D in the molding compartments effects the molding and pressing of the bricks, pressing the clay or other material from which the bricks are to be made against the fixed end walls, a a, of the molding-compartments. The feed-hopper 0 above the molding-compartments is filled with the clay or dirt after the same has been properly pulverized, and when the pressers D D are moved backward the pulverized clay is fed into the compartments by its own weight. When the pressers are moved forward to press the clay into bricks, they cut off communication between the hopper and the molding compartments, so that the clay is not fed from the hopper duringthe pressing of the bricks. The compartments are filled each time with the clay when the pressers are moved backward, so that they constitute measuring-receptacles for the clay, thus insuring uniformity in the density and quality of the finished bricks.

hen the forward movement of the pressers D D commences, the portions of the compartments next the fixed-ends a a are occupied by the vertically-reciprocating followers F F, which then occupy their highest position, having been moved thereto to discharge the bricks previously made. During the first part of the forward movement of the pressers D the followers F are depressed, so that their upper surfaces are flush with the upper surfaces of the fixed bottoms b b of the moldingcompartments, the followers thus constituting a part of the bottoms of the compartments; also, during the first part of the forward movement of the pressers the vertically-reciprocating cover E is depressed, so as to cover the open tops of the compartments, thus completely closing the compartments during the pressing of the bricks. The cover is locked in this position during the pressing operation by suitable means, which will hereinafter be specifically described. Each moldingcompartment, it will thus be seen, has a fixed end wall, a, two fixed side Wal1s,c c, abottom composed of a fixed part, b, and the upper surface of the follower during the pressing operation. The moving presser constitutes the other end of the compartment, and the compartment is covered by the movable cover through part of its extent and communicates with the hopper through the remainder of its extent. When the bricks have been compressed, the pressers move backward, and during their backward movement the cover is unlocked and raised, and the followers are also raised, lifting with them the finished bricks to a level with the receiving-table G. The swinging fingers H H thus move the bricks from the followers onto the receiving-table and the sequence of operations is complete.

The mechanism for actuating the several movable parts in the proper sequence is as follows: I is the main drive-shaft of the machine, carrying a fly-wheel, J, and is rotated by connection with any source of power. This drive rotates a crankshaft, K, which actuates the several parts of the machine by suitable connections therewith. The drive-shaft is connected with the crank-shaft by intermediate gearing, which drives the crank-shaft at a speed considerably lower than that of the drive-shaft. This gearing consists of a small pinion, d, on the drive-shaft, a large pinion, e, on the. crank-shaft, and a large interme diate pinion, f, and small intermediate pinion, g, connected together and rotating on a shaft, h, the large pinion f meshing with the pinion d and the small pinion gmeshing with the pinion e.

The shaft h has eccentric studs 7; 11, adapted to turn in suitable bearings, and to one of said studs is secured a shifting-lever, j, by means of which the shaft h may be rotated and the connected pinions be engaged or disengaged with the pinions on the drive and crank shaft. By this means the machine may be stopped or started at will.

The number of cranks on the crank-shaft will be determined by the number of the pressers to be operated therefrom. With two pressers, as shown, one crank, 70, is sufficient, and the crank is embraced by one end of a connecting-rod, L, the opposite end of which is pivotally connected to and between the two pressers D D. The extent of the throw of the crank will be determined by the desired extent of the reciprocation of the pressers.

The manner of gearing just described enables great pressure to be brought to bear upon the pressers proportional to the horsepower employed, and the machine can also work with great rapidity.

The vertically-reciprocating followers F F have pivoted to and between them one end of an oscillating lever, M, which oscillates beneath the connecting-rod L upon a fixed shaft, Z, mounted in the frame-work. The other end of the lever is pivotally connected with the lower end of a vertically-extending connecting-bar, N, which at its upper end is formed with a longitudinally-extending vertical slot, on, which embraces a fixed stud, n, on the connecting-rod L near the point where the latter is connected with the crank. The crankshaft rotates in the direction of the arrow 0, so that when the pressers are at their backward position and the followers are elevated the first forward movement of the crank will also be an upward one. This upward movement will lift the end of the connectingrod near the crank, and so raise the bar N and the end of the lever M to which the bar is connected, thus depressing the other end of the lever M and the followers. On the back ward movement of the pressers the parts are operated in the opposite direction, thus lifting the followers. The slotted connection betweenthe bar N and the connecting-rod L permits the reciprocation of the connectingrod without its affecting the lever M, and also permits the lever M to be at rest during a portion of the movement of the pressers while they are completing the compression of the bricks.

The vertically-reciprocating cover E slides upon vertical guide-rods p p on each side of the frame-work. Pivotally connected to 0p posite'ends of the cover are levers O 0, the lower ends of which are pivotally connected to the ends of crank-arms P P, fixed to opposite ends of a transverse rock-shaft, Q, having bearings in opposite sides of the frame-work. This rock-shaft has a central crank-arn1,q, fixed thereto, the end of which is pivotally connected with one end of a connecting-bar, R. The other end of this bar has an upwvardly-inclined cam-slot, 0, which embraces a stud, 3, fixed to the connecting-rod L near the connection thereof with the crank-shaft. The reciprocation of the connecting-rod L causes the bar R to move back and forth, thus rocking the shaft Q and raising and lowering the cover, the forward movement of the rod L lowering the cover, and vice versa. The slotted connection between the rod L and bar R permits the latter to remain stationary during a portion of the movement of the crankshaft.

The cover is locked when in its lowermost position by means of locking-slides S S, sliding on opposite sides of the frame-work. Each of these slides has a projecting locking-tongue, t, which slides directly over a projecting stud, a, on the end of the cover, so that the cover cannot be lifted until the locking-slides are moved away. The locking-slides are connected with eccentric studs 0 'v on opposite ends of the crank-shaft by connecting-bars T T. The eccentric studs are so located that the cover will be locked while the pressers are exercising their maximum pressure.

The fingers H H, for removing the finished bricks, are fixed to a transverse rock-shaft, U, mounted in bearings on the hopper above the cover E. These fingers normally hang by their own weight against the hopper out of the path of the cover. Fixed to the rockshaft is a projecting arm, V, which extends outward over the cover and in the path thereof. When the cover is raised, it comes in contact with the arm V, raising the same, thus rocking the shaft U and projecting the lower ends of the fingers H H forward against the bricks on the followers, thus forcing the bricks onto the receiving-table.

This machine is cheap and simple in its construction, all of its movements are positive and automatic, it is capable of very rapid work, and at the same time it enables a great pressure to be brought to bear on the bricks, thus insuring their compactness and uniform density.
