BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 349,395, dated September 21, 1886.

Application filed March 9, 1885.

To all whom it may concern:

Be it known that I, CORNELIUS N. HORTON, a citizen of the United States,residing at Peeks kill, in the county of WVestchester and State of New York, have invented certain Improvement in Brick-Machines, of which the following is a specification.

My invention consists of improvements upon a machine that has long been in use and has many merits as a horse-power machine; but attempts heretofore made to adapt it to steam-power have proved failures; and the object of my invention is to overcome those defects that have prevented its being an acceptable steam-power machine.

The reason why steam cannot always be applied to a machine that will perform well with horsepower is that obstructions that will cause a horse to stop in its travels with the sweep will, with steam-power, cause a breakage of some part of the machine, since the steam-power applied usually far exceeds that of the horses used, and cannot be either controlled or trained as can the horses.

I attain my object by means set forth in the following drawings, in which similar letters refer to similar parts throughout the several views.

Figure 1 is a side elevation of a brick-machine, showing the application of my improvements. Fig. 2 is a side view of my haul-outtripping mechanism. Fig. 3 is an edge view of a connecting-rod. Fig. 4 is an edge view of the connecting-rod used in the haul-out combination, and Figs. 5 and 6 relate to improvements in my haul-out mechanism.

A represents the mud-shaft of the machine, and stands in the center of the square box E, of which A A constitute two of the corner framing-timbers, and A is the plank bottom of said box, resting on cross-timbers A between the corner timbers. Crown-wheel B imparts motion through pinion O to the cam D. Vipers on the lower end of the mud-shaft force the clay from the box E into the iron chamber F, which is secured to the front of the machine, and of which the drawings give an end view. Aplunger moves up and down in this chamber, actuated by the connectingbar a. During the descent of this plunger a Serial No. 158,280. (No model.)

mold rests beneath the chamber on the rollers c c and just fills the space there shown.

Bar a is connected by its lower end to a cam, b, on the square shaft, one end of which shaft is shown at 0. Upon this same shaft the pressure-leverG is secured. This lever I construct substantially as shown. Heretofore the slot as was made so short that the machine could not be entirely stopped delivering clay unless the machine was stopped. The notches 1, 2, and 3 shown near the base of this slot are designed to receive a pin that passes through the bifurcated end of the long pitman H. This pitman is connected at its upper end with a. crank-pin, j, in cam D, and extends downward on both sides of lever G, as may be seen in Fig. 3, and as the cam or crank lifts the pitman H the extent of the throw of lever G will depend upon the notch in said lever, whether in 1, 2, or 3, with which pin 1; in pitman H engages. If with notch 1, of course the movement of G will be less than if engaged in 3the notch where it is now shown to be caught. It will be plainly seen that the upward movement of G will cause a reverse movement of cam b, and a consequent downward movement f the plunger in chamber F, which fills the mold below with clay, so it will be seen that the varying movements given to G varies the amount of pressure upon the clay in the mold, thus adapting the pressure to the temper of the clay.

After the mold is filled it must be pushed forward from beneath chamber F to the platform f. WVhile this mold is being filled an empty mold is inserted/from the opposite side of the machine from that represented in the figure, just back of the filled mold and forward of a bar which operates upon a rock-shaft. Rod 1' is connected at one end with this bar inside of the machine, and outside with arm h, which is secured to shaft 70, and is supported on bearings secured to the front corner timbers, one end of a j ournal-box being visible at-l. Secured to this shaft, also, is the lever m, which may be traced by dotted lines to its connection with rod on. The upper end of rod n is connected to the lever J. This lever is pivoted at o, and has its outer end hinged to connectingrod K, which is hinged at its upper end with lever L. This lever is pivoted at one end at q, and has abearing, r, at its other end, which admits of free movement up and down only. About midway between the ends of this lever I place a friction-roller, 8, calculated to engage with cam D.

Now, when a mold is filled with clay and an empty mold is in place, cam D operates to depress the lever L, which, through K, depresses one end of J, lifting its other end and rod 12 and the lever m, which throws h forward, and i, with the bar at the inner end, pulls forward the empty mold, driving the follower ahead of it to the platform f, when cam D, receding, permits these parts to fall back ready for the next mold. As a counterbalance, and to aid the several parts to resume a normal position of rest, a weight, w, is'attached to rod a. If, now, an obstruction-such as a stone-has found its way into the mold to prevent its removal, the undue pressure will automatically trip the haul-out combination. The center of fulcrum 0 should be a trifle to the right of the center of shaft 7, when any unusual pressure upon K will overcome the counterbalaneingweight WV, causing it to ascend against the stop 9, as hereinafter described. Lever at is attached to weight WV, which in turn is secured to arm 5, which is secured to an angle-iron, 6. This angle-iron may be traced by the dotted outlines. It is pivoted on shaft 7, and has an arm, 8, extending upward, and this arm carries the pivot or fulcrum on which lever J is suspended- 7 has a bearing, 2, next the framing of the machine, as will be seen by reference to Fig. 2, and also an outer bearing, 2". This outer bearing has an upward extension, 2, the object of which is to form an outer support for pivot 0, as shown in Figs. 1 and 2. To give a firm foundation to 2 and 2", I extend the plank foundation to 2 and 2. I extend the plank bottom of box E, as at A and brace it withbrackets 3 and 3". It will now be seen what effect is produced by throwing up the le- -ver 4 when an obstruction prevents the delivery of amold. WeightW falls against the stop 9, and pivot 0 describes the are indicated by dotted line 10. This lowering of fulcrum ohas the effect of lowering lever L beyond the reach of cam D, and the haul-out becomes inoperative. Pulling weight \V back to its stop 4. restores the combination to normal position again. When the haul-out is stopped, it is of course important to stop the further discharge of clay from chamber F. This is effected by releasing pitman H from its hold on lever G, which operation I will now describe.

By reference to Fig. 3, which is a top view of G and the levers it supports, except m, which is not here shown, it will be seen that lever 1 is divided at its lower end, so as to find a bearing 011 each side of G, while its upper end projects through and beyond the top edge of the likewise forked lever 1. A pin passes through 1 at 1 and by means of this pin this lever is connected to pitman H at t by con- Another pin, a, through 1 is meeting-bar t.

adapted to catch in notches in the under faces of lever 1 Lever 1? is extended into a handbar toward the front of the machine, and has its other-end pivoted to an extension of G at 'w. Now, it will be obvious that if lever 1 be raised from the position now shown pin a will be released and the weight of the pitman II will cause it to fall back from its engagement with notch 3, and, instead of lifting the lever, pin 12 will travel in the slot 00, and hence op eration of the press will cease.

Lever x (which is not shown in Fig. 3, to avoid confusion, but is shown in Fig. 1) is pivoted to the outer end of lever 1 at one end,

and its otherend is made circling for a good hand-hold, and has an eye which slides over the small end of lever 1 If the present position of pin 12 of pitman H should require to be changed from notch 3 to notch 2 or 1, it can be done without stopping any part of the machine by simply grasping m, lifting it to free i 1 from pin a, and by pulling it forward draw uinto the desired notch, and by dropping this lever 011 pin it again the change has been accomplished. So, after the pressing mechanism has been stopped, it can be at once set in motion by lifting and pulling forward lever 00,- but to insure the engagement of pitman H and lever G at a time when no mischief can ensue, a safeguard is provided. Connecting-bar t is furnished with a projection, y, and the lever G with a curved projection, Then a of pitman His traversing slot as, this projection 3 travels within the are provided by 3 and cannot be brought forward untilv arrives at the point for approaching the notches l 2 3.

My method of making connecting-rod K. is set forth in detail in Fig. 4., in which B- is an edge view, and B a cross-section through line b. I make the rod in two pieces, the half 11 at its jointed end being provided with short flanges beveled at the inner edges to receive the eorrespondingly-beveled part of I), as shown more clearly at I/. By using this flange I am enabled to use a single bolt to secure the two halves together. At 0 is shown a slot formed for the reception of a wedge-like key, as seen in Fig. 1, by which the length of the rod may be varied to the fraction of an inch.

I wish now to refer to the rod '5 of the haulout combination. The old method of making this rod is shown at Fig. 6, in which z" is the bar operating back of the molds, and which is carried upon arms similar to h, Fig. 5. Through this bar an eyebolt, j, was inserted, as shown, provided with a nut and long thread for adjustment of length of bar 2'. Then by means of a chain-link, 7c, and an eye on the end of the bar the connection was complete, as shown. The result was a combination constantly wearing and stretching. Fig. 5 will show how I attach the bar 23 by an eye directly to a pin in h, and then by a long nut and right and left hand threads on the two inner parts of the rods I have a rod that is firm and adjustable at any time from the front of the machine.

As constructed heretofore, bar (Z has been IIO 5 the frame, I bring the bar d directlyzin front of post A, thus removing it from all liability to damage. A similar bar acts upon the opposite side of the machine. To avoid setting chamber F ineonveniently far forward, I mor- IO tise out A a trifle to accommodate bar d, as

shown by the dotted line at the upper end of the bar.

Having fully described my invention, What I claim, and desire to secure by Letters Pat- 15 cut, is

1. The combination, in a brick-machine pressing -mechanism, as described, of the leversG, 1, 1 and w, pitman H, and rod t, united and operating together substantially in 20 the manner described.

2. The pitlnan H and rod t, provided with arm y, combined and operating, as described, with levers 1 1 x and the cam G, provided with projection 3/.

3. In a brick-machine press-tripping mechanism, the combination, substantially as sh own, of the bifurcated lever 1, pin it, notched lever 1 and hand-lever m.

4. In a brick-machine haul-out, the combination of cam D, roller 8, lever L, connecting rod K, lever J, rod n, lever m, arm 71, and rod i, united and operating substantially as set forth.

5. I11 a brick -machine haulout-tripping mechanism, the combination of angle-iron 6, fulcrum 0, pivot 7, standards 2", arm 2', lever 5, weight W, lever 4, and stops '4 and 9, combined and operating substantially as shown.-
