BRICK-MACHINE.

Specification of Letters Patent No. 24,343, dated June 7, 1859.

T 0 all whom it may concern:

Be it known that I, WILLIAM S. WATSON, of Madison, in the county of Jefferson and State of Indiana, have invented a certain new and useful Improvement in Brick- Making Machines, of which the following is a full, clear, and exact description, refer ence being had to the accompanying drawings, which form part of this specification, and in Which Figure 1 represents a top view or plan of a machine embracing my improvement, and Figs. 2, 3, 4c and 5 longitudinal vertical sections thereof showing the operative parts in different relative positions. Y

My improvement relates to compressing bricks after they have been molded and partially dried, and is not calculated or designed to mold brick or to subject it to pressure when in the green state.

The bricks, previously to their introduction in the machine represented in the accompanying drawings, maybe formed either by hand or machinery, as desired, subject to light or heavy pressure to reduce them to form and consistency. Pressure however applied to bricks when in their green state or in the act of molding them does not accomplish all that is desired in regard to their form, appearance, and consistency. Said bricks may be delivered from the molds or press in a moderately regular and solid condition, though their adhesive natureinsuch a state operates against a close or solid finish to them on their exterior; but, being soft and pliant, they are liable to get out of shape in after handling or action on them preparatory to becoming hard and dry, and the drying process causes them to crack on their surfaces. I take the brick therefore after it has been moldedand partially dried, when it has been deprived of much of its moisture and stickiness and is of moderately regular form and certain solidity or consistency but not too solid or hard, and subject it to pressure as hereinafter described and whereby I secure a more solid and regular shaped brick and one of closer and finer or smoother finish on its exterior. The brick is afterward dried, or its drying finished, in any suitable manner. To carry out this intermediate process or action on the brick after it has been molded and partially dried, I necessarily employ in the machinery for the purpose certain devices, such as plungers and so forth, well known to belong or as forming constituent parts to or in brick presses arranged to press and discharge green brick automatically, but such devices have here a peculiar construction and action or relative arrangement given two brick receiving chambers, a corresponding number of plungers, and so forth, but

, this disposition is optional and should be governed by the capacity required of the machine, the action being the same Whether there be one, two, or more plungers and other parts in immediate operating connection with the plungers, simultaneously at work in the one machine. The following description corresponds with the arrangement shown in the accompanying drawings.

The frame (A) of the machine may be constructed in any suitable manner. Across this frame is arranged a driving shaft (B), to which revolving motion may be communicated by hand, horse, steam or other power, and on which is hung a fly wheel (C) to ease and make more regular the action of the machine, and on which also is hung a pinion (D) working into a spur Wheel (E) of an actuating shaft (F) to increase power and give the necessary movement to the operating parts hereinafter referred to. ter shaft (F) carries a cam (G) arranged towork in a slot (a) of a sliding frame (H) and to operatethe latter in an intermittent reciprocating manner in direction of the length of the machine, in which traverse said frame is suitably guided. To the forward end of this sliding frame (H) is attached so as to have intermittent reciprocating motion with it, a double press box made up of chambers (I, J one chamber This lat-o oneither side of a stationary cross block is otherwise of open build so as to admit of being closed at intervals, top and bottom, by slides (b, 6 having an intermittent reciprocating action, in, reverse directions, above and below andalternately to either side of the stationary block (K), also having, in addition to. suchindependent action,

This double press box is of close cona general motion at intervals, in the same direction, and in concert with the double press box.

On the to of the double press box is a double chain ered feeding box (M M to facilitate entry and the proper disposition of the bricks to or over the intermittent reciprocating press box, and the top one of the slides last referred to, traversing at intervals to form a bottom to either chamb er alternately of the feeding box, serves to hold the brick up in the feeding box till the press box is in a proper position and ready to receiy e it; while the lower one 6 of these slides serves to hold the brick, after it has dropped from the feeding box, in proper position for. its encompassment by the press box (I or J) and in close proximity to the stationary block (K) against which the brick is pressed by the plungers (L or 'L These specified independent and joint actions of the double press box (I, J) with its double chambered feeding box (M M and intermediate top and bottom slides (b, 6 may be effected as follows.

The sliding frame (H), which reciprocates at intervals the double press box with its feeding box, has connected with it a sliding cam plate (N) arranged to embrace the actuating shaft so as to permit of,'

at certain times, free motion along with the sliding frame (H) as well as, at intervals, an independent intermittent reciprocating movement of it along said sliding frame (H), on which said cam plate (N) may be hung and guided by pins (0) that fit through slots in the cam plate and serve as supports, guides, and stops thereto.

The cam (G), that actuates the sliding frame (H), serves as the driver to this cam plate (N) in its general movement with the sliding frame (H), while a cranked arm ((Z) attached to the actuating shaft (F) answers at intervals to give the cam plate (N) its independent reciprocating motion by means of the cam formations (e, (5 on said plate when the revolving cranked arm (d) comes in contact-with said formations. This cam plate (N) is connected, by means of a front cross bar (7) and suitable side strips,

with the lower intermediate slide (F) of the press box, by which arrangement said slide reciprocates 'conjointly at times with the press box and at times independently of it.

The top intermediate slide (b) is also made to move at times conjointly with the press box and its sliding frame (H), and at times independently thereof and simultaneously 7 with but in reverse directions to the corre-' sponding lowerslide (6 by means of a sliding brace (0) extending from said top slide (1)) and hung by a slotted provision made in it on a pin to the slidingframe (H), which pin serves as a support, stop,

cam plate (N) and brace plate and guide to the brace; and further by means of a pinion (P) hung on the sliding frame and arranged to gear on opposite sides of its periphery with the brace (O) and cam plate (N) to secure reverse'actions to the two slides (11, L when moving independently of the sliding frame (H). A beam or lever in gear with the brace and cam plate might take the place and would be the equivalent of this pinion connection of said brace and cam plate.

From this description and inspection of the accompanying drawings, the relative actions of the press box and its slides, ashereinafter explained, will be readily understood. v V

The plungers (L, L) of the pressing chambers (I, J) are connected by a frame (h) so that when the one plunger recedes from the stationary block (K) the other advances toward it. These plungers are thus made alternately to advance and recede, at intervals, by means of eccentrics (Q) on the actuating shaft (F) and eccentric rods (R) which connect with the frame work of the plu'ngers. The relative periods at which the plungers act will be presently explained.

An endless apron conveyer (S), set in motion by pulleys (2', 7".) and a belt (l), or otherwise, may be arranged under the press box to receive and carry off the bricks as they are delivered from the machine, or any other desired conveying arrangement may be adopted.

Now, supposing the parts to be in the position represented in Fig. 2 of the drawing, the double press box (I, J) has then completed its back movement and carried along with it the slides- (b, 12 from the position they are shown to occupy in Fig. 5. The one chamber (M of the feed box is then, and-during the movement of the press box from its position in Fig. 5 to that in Fig. 2, and it may be a little prior to as well when the press box remains stationary, inclosed at its bottomby the top slide (2)) and consequently in condition to receive a brick. .Arrived at this position (Fig. 2), the cranked arm ((1) is about to strike the cam formation (e) of the cam plate (N), striking which and during the traverse of the cranked arm to its position shown in Fig. 3, it causes the (I to move the top and bottom slides (b, to their position shown in Fig. 3, making the top slide, (6) withdraw to drop the brick from the'feedingchamber (M against one side of the stationary pressing block (K), and in so withdrawing causing said slide (1)) to pass over so as to form a bottom to the other feeding chamber (M) and put it in a conditionv to receive a brick; and simultaneously making the bottom slide (12 arrange itself in position to receive the brick droppedfrom the feeding chamber (M The press box then moves forward to the position shown in Fig. 4:, the plungers (L, L also moving in like direction but at a slower ratio, and the top and bottom slides (b, 6 moving with the press box. The one chamber (J) of the press box has then embraced the brick which was dropped from the feeding chamber (M The press box then remains stationary but the plungers continue their motion in the same direction till the one plunger (L has exerted the necessary pressure on the brick in the chamber (J), as shown in Fig. 5. During this latter action of the plungers, the cranked arm (a), in moving from its position in Fig. 4 to that shown in Fig. 5, has acted upon the second cam formation (6 of the cam plate (N) and moved the slides (b, 6 so as to drop the brick from the second feeding chamber (M) and hold it on the opposite side of the stationary pressing block (K), and the one slide (2)), in thus moving, passing over again to the first named feeding chamber (M so as to put it again in condition to receive a brick. After this, as shown in Fig. 5, the pressing box with its slides is then moved back to the position shown in Fig. 2, when the pressed brick drops from the right hand pressing chamber (J) on to the conveyer beneath, the plungers also moving in like direction to the pressing box in thus returning to its original position as exhibited in Fig. 2. The like action is repeated alternately for each pressing chamber and plunger, the plungers continuing their motion after the pressing box has ceased, as already described.

Here I would observe that, as either pressing chamber (I or J) and its plungers (L or L recede simultaneously from the stationary pressing block (K), after the brick has received its pressure, the box or chamber as well as the plunger act-s to draw the brick and secure it from sticking against said block, while the receding movement of the box or chamber being faster than that of the plunger the brick is soon left unsupported and made to drop. By such arrangement too, the plunger clears the box or the box in overtaking the plunger clears itself of any matter likely to collect and clog; while the top and bottom slides (72, 6 serve by their action to secure cleanliness and freedom from obstructing matter for reception of the brick. The feeding box with its chambers (M M might be dispensed with, but it greatly facilitates the placing of the brick in right position for feed, especially when entering the brick as the press box is in motion as when moving for instance from its position in Fig. 3 to that occupied by it in Fig. 4. The brick too might be entered without the agency of the top slide (1)), but the utility of the slides (1) b needs no further comment. Such machine, while not adapted to molding and compressing brick in its green state, is very eflicient in compressing molded and partially dried brickits intended purpose.

What I here claim, as new and useful, is:

1. The combination and arrangement with a stationary pressing block (K), of an intermittently reciprocating press box formed with one or more chambers (I, J), and provided with one or more plungers (L, L having a joint motion with the press box and an independent movement in relation thereto essentially as and for the purpose set forth.

2. The combination, with the intermittently reciprocating press box, of the top and bottom holding slides (12, 19 or either of them, arranged to move conjointly with the press box and independently of it substantially as specified.

3. Mounting the intermittently reciprocating press box with a feed box having one or more chambers (M, M essentially as and for the purpose herein set forth.

In testimony whereof, I have hereunto subscribed my name.
