SIEECIFICATION forming part of lLetters Patent No. 497,322, dated May 16, 1893.

Serial No. 401,206. (No model.)

.T0 all whom' t may concern:

Be it known that I, CHARLES H. HORTON, of Vellington, in the countyof Lorain and State of Ohio, have invented certain new and useful Improvements in Brick-ll/Iachines; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art t-o which it appertains to make and use the same.

My invention relates to an improvexnentin brick machines and it consists in certain novel features of constructions and combinations of parts as will be hereinafter described and pointed out in the claims.

In the accompanying drawings Figure l lis a horizontal sectional view. Fig. 2 is an end elevation with gear wheels removed and parts broken away. Fig. 3 is a view of the same end with gearing attached, and Fig. 4. is a detail.

A represents the frame of the machine or mill. The clay is dumped into the mill at A and forced in the direction of arrowsit being forced through opening between the two mills at A2 by wi per G4 to the second mill through which it is forced in the opposite direction to the press box F2 into which it is forced by In passing from the first to the second mill the clay makes a complete turn mixing it in a thorough manner and by combining the two mills a great number of knives or blades may be used without making eXtra long shafts which are both expensive and liable to twist or break. The wipers D4 over the presses are made as narrow as consistent so as to assist in pugging .the clay when the press is closed or not working.

In working the machine power is applied to pulley B which is keyed to shaft B2 and on which is fastened pinion B3 and that in turn meshes into spur wheelB4 which is keyed to shaft B5 and on the opposite end of said shaft is keyed pinion B6 that meshes into spur wheel Bl'lon which is the driving crank pin for the mud presses on the roll driving mold press. A connecting rod B8 connects wheel BT to loose arm Bg to which is hinged dog O2 at a point O3. Toothed sector C is keyed to the outer end of mud press shaft C4 and arm B9 works loosely on shaft O4. Smooth sector O5 is also loose on shaft C4. To the opposite end of said press shaft is keyed a segment gear O7 which in turn meshes into one of the same pattern on the opposite mud press shaft and serves to drive the mud press D.

VThe two rocking or oscillating mud presses work'entirely in the mud so that any leaking which may occur passes back into the mud. By using two presses instead of one as heretofore both ends of the brick are pressed alike andthe blades being being narrower the presses work easier and consequently can be driven with lessfpower.v

It is desirable that in case any hard substance such as stone or sticks should be caught between the presses that there should be a relief when the required pressure is obtained and to attain the desired' result dog C2 is jointed at H2 that point being just above the center line from point of contact on toothed sector and back end of dog where the same is pivoted.

A spring H3 is arranged to give the desired strain and set screw P is tapped into front part of dog the head striking the joint where the two parts of the dog come in contact. If the screw be turned out it will throw the joint farther apart raising point H2 making the dog buckle underalighter strain. If more power is needed the screw is turned in allowing the point H2 to settle nearer in. line of contact with sector hinge and dog. In case of undue strain on the dog, the hinge when spring strikes it rises allowing the dog to buckle up and pass over the notches without pushing them any farther ahead as shown by dotted lines Fig. 3.

It is desirable that the dog should'move back over the notches without noise and also to avoid wear by the dog dropping back into each notch as it passes over it. To accomplish this I pivot a loose earH4 on the dog at point H5 above the centerv so that it will fall y into position by its own weight a stop pin H7 being provided to prevent the ear going too far over. A shelf or projection I-I6 is placed on toothed sector C this being as long as the enti-re travel of the dog and the ear of the dog is long enough to carry the dog just clear of the notches when it is being drawn back but whenever it moves forward the ear will lean forward allowing the dog to take its place in the notches as shown by the dotted lines Fig. 4.

A projecting lug HS on sector C serves to draw back said sector by engaging back of loose arm B9.

Roll E is placed on back side of wheel B7 so as to come directly under actuating arm E2 Fig. 2 being placed the rightdistance from thecenter to give the necessary travel of the mold press E8. `When motion is imparted to Wheel B7 roll E cornes in contact with the under side of arm E2 raising it, that being connected to mold press arm E4 by connecting rod E5. Arms E4 are keyed to shaft E? and on EG are keyed two legs E7 (only one shown) they being placed on said shaft as far apart as the length of the mold. Mold press E8 is hinged at the back end to legs E7 the other end being carried by rolls E9 (one not shown.)

It is desirous that there should be a relief of the mold press mechanism in event a mold is caught wrong or any undue resist-ance to the mold press be encountered and to accomplish this I use a toggle joint K held in position by a spring K7 on the back end of the link K4. The arm E2 is extended downward as at K'2 and provided with a slot running from pivot pin E3 nearly to the lower end as shown by dotted lines K3. Onto pin E3 is hinged the upper end of toggle and the lever end is hinged to actuating arm at K5. In event of an extra pressure the toggle buckles up against spring resistance K7 as shown by dotted lines the slot in arm E2 and extension K2 being moved up at the back end instead of the front as usual. It is also desirable that a relief device be had for the press box F2 and molds in event of excessive pressure or a stone or hard substance being caught in the mold. A series of doors are forced directly over where the mold is delivered forming a part of the f ront of the press box O Fig. 2. These doors are hinged at O2 and swing outward being held in position by toggle joint Oasprlng O4 arranged to give the toggle the desired tension similar to the dog and mold press toggle above mentioned.

The extended spring serves as a handle in case the door is to be opened by hand. A slight pull releases the tension on the spring allowing the door to come open easily.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination with mud presses, and gearing for operating the latter, of a toggle joint pawl connected with the gearing and adapted to operate in connection with the mud presses, substantially as set forth.

2. The combination with rocking mud presses, of a toothed device keyed to one of the mud press shafts, and atoggle joint pawl arranged to cooperate with said toothed device, substantially as set forth.

3. The combination with mud presses, of a toothed sector keyed to one of the press shafts, a yielding toggle joint pawl adapted to cooperate with the teeth of the sector, and means for holding the pawl away from the teeth while retreating, substantially as set forth.

4. The combination with press box, mud presses, mold press and gearing, of slotted bell crank arm, toggle joint connections and means for connecting said arm with mold press, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

CHARLES Il. HORTON.
