BRICK-MACHINE.

$PECIPICATION forming part of Letters Patent No. 304,283, dated August 26, 1884.

Application filed May 7, 1884. (No model.)

To all whom it may concern.-

Be it known that we, PORTER L. SWORD and CHARLES D. SWORD, of Adrian, county of Lenawee, State of Michigan, have invented a new and useful Improvement in Brick-Ma chines; and we declare the following to beafull, clear, and exact description of the same, such as will enable others skilled in the art to which it pertainsto make and use it, reference being had to the accompanying drawings, which form a part of this specification.

Our invention consists of the combinations of devices and appliances hereinafter specified, and more particularly pointed out in the claims. I

In the drawings, Figure l isaside elevation ofa machine embodying our invention. Fig. 2 is an end elevation, with the brick-carrier removed and the re-presses ready to begin the re-pressing of the brick. Fig. 3 is a cross-sectional view at right angles to the brick-carriers. Fig. 4 is alongitudinal central section of the device. Fig. 5 is a plan view with the tub removed. Fig. 6 is aseparate view of opposite sides of the large camwvheel. Fig. 7 is a view of a modification of the repressing mechanism. Fig. 8 is a separate view of the brick-molds; Fig. 9, a separate view of the table; Fig. 10, a separate view of the oiler; Fig. 11, another form of oiler; Figs. 12, 13, 14, separate views of the mechanism for actuating the lubricator K.

Our invention eomprehends the general structure as a whole, and also the particular features which are separately enumerated in the claims.

A is a tub, in which the brick metal is charged. B represents the tempering-blades, whereby the mass is tempered in the usual way. The tempering-blades are secured to and revolved by the upright shaft 0, which at this point is preferably squared for the ready attachment of the blades. The shaft 0 passes down and at its base there is a large gearwheel, D. This in turn meshes into the pinion D on the vertical shaft D". At the upper end of this shaft is a beveled gear, D", which meshes with a pinion, D*, on the shaft of the driving-pulley D, which drives the entire machine.

E is a reciprocating table, in which the brick-molds are situated. This table is slotted vided with a yoke having anti-friction rollers e. Y

F is a cam-leverv located on the shaft 0. This cam-lever is embraced in the yoke between the said anti-friction rollers, so that as the cam-lever revolves with the 'sliaft O it causes the table E to reciprocate back "and forth. The bottom of the'tub A is provided with openings 'Afintoirhi'ch the br ick metal is swept by the sweep P.- :The titblGEdSIJlO- vided with brick-molds E, corresponding-with the openings A. When the brick metal is thus deposited in the openings A, the revolution of the cam-lever F drives the table out toward the edge of the machine, beneath the presses, which we will now proceed to describe.

G represents a press. There are two presses corresponding with each of the openings A, each of said openings corresponding to a pair of brick-molds beneath. pivoted at g to the frame of the machine. A pitman, G, connects the same with a lever, G, which is hinged at g to theframe. This lever G has an arm, G, projecting down to the base of the machine, and is here engaged with a sliding or driving bar, G. This bar has projecting studs and anti-friction wheels G which project into and engage with the cam d in the top of'the gear-wheel D at the base of the machine. This cam is so arranged with respect to the movements of the table E that it causes the bar G to reciprocate at the proper moment to draw upon the arm G, and so actuate the presses G. The upper cam, (Z, is so shaped with respect to the cam F that the presses G- are caused to come down and operate while the table E is stationary beneath them. The presses then recede and the table E moves for ward to the re-pressing apparatus, which we will now describe. a r

H is a die upon which the brick metal rests in the mold. A pin, H, projects downtherefrom. H represents the uprights, andI I the cross-piece, of the frame which supports the ress-plates and resistance-plates H;

I is a shaftjournaled eccentrically in the lower ends of the uprights H This eccentrio shaft has projections I connected rigidly therewith. An armor arms, 1 project downward and engage the pitman 1 which in turn These presses are is connected with theplate or slide I, from which project lugs and anti-friction rollers I into the cam d on the lower face of the gearwheel D. Now, the brick-mold on the table E,havin g been slid forward beneath the pressplate H, the pin H comes into contact with the eccentric shaft I. Now, as the pitman I is forced outward from the machine, it rotates the shaft I in its eccentric bearings, which in turn rises upon the pins H and effects a powerful re-pressure upon the bricks in the molds. The eccentric I being firmly journaled in the uprights H, the outward thrust upon the arm I simply serves to rotate this eccentric shaft I in its bearings, and it is this rotation upon the eccentric journals which effects the upward pressure on the pins H. As soon as the pressure has been thus applied the motion of the pitman I is reversed. The arms I will at this moment be well raised about the trip 1. The first effect of thebackward motion is to quickly rotate the shaft I, relieving the pressure and slightly lifting the frame H", so as to separate the press-plates H from the brick-molds. The further backward motion serves to bring the arms I in contact with the bearings i, and the frame is now raised bodily about these bearings i as pivotal points. This, it will be observed, will cause the eccentric shaft I to be revolved somewhat farther, and the effcct of this increased revolution is to still further loosen the bearing of the eccentric shaft upon the pins H to the same extent, separating the plates H from the bricks. This upward motion of the frame H H has lifted the bricks up out of their molds, and they rest upon the dies H, with the presser-plates H lifted free from the bricks.

We will now describe how the. bricks are removed from the machine onto the carrier.

J is the carriage which supports a continuous belt, J, which receives the bricks as they come from the machine. This carriage J is connected with the table E, so as to move backward and forward with the table.

K is the oiling device. It consists of upper and lower rollers, k, which are preferably covered with woolen cloth, sheep skin, or other similar substance, and receive a supply of oil from perforated pipes which in turn take their oil from the reservoir k and flexible pipe k This oiling device isconnected with rods K, and serves at the same time to force the bricks off from the plates H onto the continuous belt J. It is accomplished as follows: L represents arms, which are in like manner connected with the table E, and move forward and backward with it. L represents a lever, and L represents another lever. These two levers are pivoted at Z to the frame. The levers L and L are connected by arms L and L, and support a weight, L at their junction. Z is a projecting pin on the carriage J, and Z a notch in the arm L. Now, as the table E moves backward the oiler K is left in the position shown in Fig. 4, because the pin Z has engaged the levers L and L and forced the -L and L stand' erect.

oiler back to this position. Subsequently,when the table E moves forward the knives M shave the surplus brick metal from the top of the mold, the mold passes beneath the oiler and into the re-presser. This receding of the table carries with it the carriage J, and the levers Just as the carriage, however, reaches nearly the end of its stroke the notch Z engages over the bar Z Now,

when the tableE starts again on its backward motion, the arm L causes the lever L to tilt about its pivotal point Z, thus drawing out the oiling device K, which forces the bricks out upon the endless belt J. In the further movement of the carriage the pin Z comes in contact with the lever L, and as it forces that lever forward the link L is forced up against the arm L, lifting its notch P free from the bar I. The pin Z on the carriage then forces the levers L and L" forward with the carriage and returns the oiler K to its" original position back of the re-presses.

We would have it understood that the device for discharging the bricks, as above explained, is a novel feature of our invention, and we would not therefore be limited in its employment to a device in which the lubricating appliances are attached thereto, for the lubrication may be accomplished in other ways.

i is a trip, the purpose of which is as follows: When the pitman I moves out from the machine, and thus permits the frame H H to descend, the arm 1 strikes this trip, which serves to stop the downward motion, causing the eccentric shaft to stop at this point, and by a further revolution to lift the frame so as to hoist the plates H* slightly and permit the brick-molds to enter freely beneath them. The farther outward thrust of the pitman I lifts the arms I sufficiently far to permit the shaft I to drop down slightly, thus-again .bringing the plates H squarely down upon the brickmolds before the re-pressure is begun. The farther outward thrust of the pitman is what accomplishes the repressure upon the bricks by the rotation of the eccentric shaft J. Instead of employing the trip z", any other suit able contrivance may be employed-as, for instance, that shown in Fig. 7, in which i repre sents a lug, through which the bolt is passed, and secured by jam-nuts above and below, as shown. Then upon the eccentric shaft we would locate-a lug or pin, i, which in descending would strike against the top of the bolt Z, and thus check the downward movement of the eccentric shaft I, as before explained. This bolt Z admits of adjustment up and down, so as to regulate its action upon the eccentric shaft.

M represents scrapers, which dress the brick metal off from the presses G. as they recede from their work. Similar scrapers, M, are located at the sides of the presses.

N represents one or more rollers,which may be located over the eccentric shaft I to receive the direct bearing of the pins H. The object IIO ,Fig. 11.

of this roller or rollers is simply to permitthe pin to drop down from one roller to another as the table recedes, instead of dropping down through the whole distance at once. Of course these rollers may or may not be employed; or an inclined plane may be employed for effecting a similar purpose.

1? is a sweep keyed to the shaft 0, its office being to sweep the brick metal into the openings A above the molds.

Q represents bearing-rollers, which support' the table E. These rollers are supported by journals Q, which are capable of adjustment up or down, so as to locate the table always in its proper position.

For varying the thickness of the bricks we employ a small pin or stop, h, beneath the brick-dies, and to reduce thethickness we remove the pins and locate washers h upon the pins, which raise the dies just to that extent. All the parts of the apparatus are capable of adjustment, so as to compensate forwear and to properly align and regulate the parts.-

The various parts of the machine are made interchangeable to suit any other machine of the same size, so that repair parts may be supplied at any time and may be at once adjusted into the place of the piece broken or removed.

The oiler K may be constructed as shown in The upper lubricating appliance consists of a piece of felt or other capillary substance secured to a suitable support and adapted to lubricate the re-presser plates by being drawn across in contact with the latter. The lower appliance may be similar to the upper, or may consist of a roller. Both forms are shown in this figure.
