JOSE-PH I. NIETERS, OF ST. LOUIS,- MISSOURI.

BRICK-PRESS.

lb all whom it may concern:

Be itknown that I, JOSEPH J. NIETERS, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvem'ent in Brick-Presses, of which the following is a full, clear and exact description, suchas will enable othersskilled' in the art to which it app'ertains-to make and use the same, reference being hadto the ac-' companying drawings, formlng part of this specification, in which I Figure 1 is a'front elevation of a brick press constructed in accordance with my inventio Fig. 2 is aside elevation of said rna- 3 is a vertical sectional view showing't e chargirw device in its-forw, rd osition after it has filled the mold box with cay; Fig; 4 is a transverse sectional view throu h the hopper;-and Fig. 5 is a vievnsimichine lar to 'ig. 3 but with the parts in a different havinfg -vice r keeping the faces of some 0 the mold members and also other parts of the machine lubricated. 1

Another object is to provide a novel form ofdevice for grinding up clay fromwhich the bricks are formed while the clay is in the hopper of the machine; and still another ebject of my invention is to provide a handpower brick press which is of simple construction and can be operated easily.

Other desirable features of my invention will be hereinafter pointed out.

Referring to the drawings which represent the preferred form of my invention, 1 desig- Hates the hopper of the machine into which the clay is thrown, the clay being in its naturalcondition just as it is taken from the bank. The mold box 2 is arranged below the hopper and slightly in front of same, and extending rearwardly from the mold box is a table 3 on which the charging device 4 is reciprocatingly mounted. This charging do- Viee is provided at it's fronL end with an Specification of Letters @atent Application filed March 12. 1907. emu No. 361.973.

opening 5 into which some of the clay in the hopper drops when the charging device is in its rearward position, as shown in Fig. 5, said charging device being moved from its rearward into it's forward position, as shown in Fig. 3, to permit the clay to drop into the mold box.- A lower lunger 6 reciprocates in the mold box, and arranged above the mold box and in alinement therewith, is an impel-(plunger 7, these plungers being moved tower /each other to com rose the mass of clay in the mold box and t us form a brick, as shown in Fig. 5. After the brick has been formed the upper plungerandthe lower plunger both move upwardly so as to carry the brick out of the mold box, the charging device 4 having previously been moved into its rearward position so that the front end thereof is located at the rear of the brick. When said charging device moves forwardly to carry a fresh char e of clay to the mold box the front, end of t e chargmg device will engage the brick which at this time is en ported on the lower plunger flush with tie top of the mold box, and will ejlect said brick onto an ehdless conveyer or be t 8 extending forwardly from the maohine and having its upper surface arran cd-in the same horizontal plane as the tab e 3.' This endless conveyer is moved intermittently so that after a brick has been deposited thereon the next brick that is moved onto said conveyor will not-contactwith the brick that was previously laced on same, thereby preventing the brie s from rubbing against each other or marrmg the surfaces and .thus spoilin thereof as would lie apt to result dueto the fact that when the bricks are ejected from the mold box they are very moist'and comparatively soft. i

In order that the bottom face of the upper plunger 7 may be kept thoroughly lubricated and also the sides of the mold box and the upper surface of the table 3 on which the charging device reciprocatvs, I have )rovided the )ress with an oiling device W ich consists of clamped between the front end of the charging device and a bar 10 that issecured thereto by means of bolts or in any suitable manner, the upper end of 1 his piccc of fibrous material projecting above the upper edge of the charging device so that it will'contact with the underneath face of the upper pluna piece of fibrous material 9 material 9 and thus sat iii-sting with oil, the upper edge of ths fibrous pieos 9 sppiyw .ing the oil to the bottom of the upper piunge'r', and ths Laws-edge oi plying the oil to i sids of the modhozi: 0i" rather to the upper of the sash ox so: oii ass flow downtho .ie faces tool-oi sndioss i 8 onto which the sis- 111* o fsd th *"eti from L box travels o mounts v x.

The normal position of the lower plunger can be varied by means of an adjustable contact screw 36 mounted machine and a apted to contact with the inclined lower face at the inner end of the oscillating member 25. i

The die late 37'which forms the pressing face of the ower plunger, is also of novel con struction in that its engaging face is perfectly smooth, said plate being provided on its underneath side with a screw which extends through an opening in the top of the plunger and has a nut 38 mounted thereon to secure said plate in position. In the machines ing devices that secured the die plates to the longer extended clear through to the pressmg faces of said lates so that these fastening devices wou d leave their imprint on the brick.

In order that clay in its natural state may be usedin the machine I have provided the hopper with means for grinding up or pulverizing the clay, this means consisting of transversely extending grate-bars 40 over which a rotary kniie carrying member travels. This rotary knife-carrying member versely of the hop er, the arms of said spiders havin knife blat es 43 secured thereto. A knife blade 44 is connected to arms 45 that are loosely mounted on the shaft 42, these arms being of less length than those of the spider so that the knife blade 44 will be located within the circular mth in which the knife blades 43 travel. This knife blade 44 coo crates 'with those connccted to the s i ers 41 and thus forms a shearing device that acts to cut the clay up very line, the knife blades 43 also cooperating with the grate-bars to sever and grind up the clay in the hop er.

i. The sliaft 42 is rotated bymeans of belts or ropes 46 secured to the lovers 21 and wound around rooved pulleys 47 on the opposite ends of the shaft 42, a weight 48 being secured to the end of each of said belts so as tion and also rotate the knife-carrying membar in the opposite direction to that in which it is rotated when the lovers 21 are depressed.
