Application filed February 23, 1906. Serial No. 302,357- 7 To all whom it may concern: roller F, located beneath the cam-shaft D,is

Be it known that I, GARABED' G- Haem- NIAN, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York", have invented certain new and useful Improvements in Molding-Presses, of which the following is a specification.

This invention relates to improvements in presses, and particularly to improvements in presses for automatically molding, shaping, and compressing blocks-such as payingblocks, tiles, building bricks or blocks, briq'uets, &c.from an asphalt mixture or clay or a cement mixture or any other suit- The object of my invention is to provide a new and improved machine of this" kind naled.

' interchangeable shoe E,

which is simple in construction, strong and durable, which properly shapes and firmly compresses the blocks, and at all times feeds the material to the molds as required.

In the accom anying drawings, in which like letters of re -erence indicate like arts in all. the figures, Figure, 1 is a vertica transverse sectional view of my improved press, parts being broken away. Fig. 2 is a vertical longitudinal sectional view of the same on aslightly-reduced scale. Fig. 3 is a plan view of the machine, parts being in section. Fig. 4 is a detail view of the same. Fig. 5 is a horizontal sectional view on the line :0 m of Fig. 4 on an enlarged scale. Fig. 6 shows several parts in perspective view.

The entire machine is supported on a heavy cast base A, rovided with brackets in which the main riving-shaft B is jour- This shaft B carries a fly-Wheel B, a tight-belt pulley B and. a loose-belt pulley B. On this shaftB a worm C is fixed, which engages a worm-wheel C, secured on the horizontal cam-shaft l), which is journaled in the body of the machine and in a standard D at one endof the base and preferably made integral with the base. This camshaft carries a main operating-cam E, which I n l i is preferably provided with a removable or whiclf 'can act on the antifriction-rollers Fand F, located, respectively, vertically above and vertically below the cam-shaftl) The roller F above theeam-shaft is mounted in the forked lower end of a vcrtically movable plunger G, which is guided up and down movements in a ions, of the body part of the machine.

' thus follows that {The mounted in a fork of a cross-piece or yokeH, the ends of which enter slots 1, formed in the flattened portions 1 of two reciprocating rods J-, which are guided in their vertical movements in. the to of the machine, and these rods are also guided b their flattened slotted lower portions 1, which move up and down in grooves I of the machine frame or body. The rods J are connected at their upper ends by a yoke or cross-piece .L, from which a plunger L extends downward. It

for one complete revolution of the cam-shaft l" in the direction indicated by the arrow in Fig. 1 the plunger G is first forced upward, and later on the plunger L is forced downward by the action of the cam E on the lower cross-piece H and the upper cross-piece L, connected therewith by the rods J. The plunger G descends under the action of its own weight, and thus its roller F is at all times kept in contact with the edge of the cam E; but provision must be made for raising the upper plunger L after it has been forced down.

-. As shown in Fig. 4, the cam-shaft D passes thro ugh the slots 1 in the lower flattened portions of the rods J in order to permit such rods to reciprocate, and at said flattened portions of the rods J a cam K is secured to the cam-shaft I), one at each side of the machine, and the edge of this cam is in contact with a roller K,projectin g laterally from each rod J.

As shown in Fig. 4, the cams K are so shaped that approximately five-eighths of the circumference serves for lifting the rods J, and the balance of the edges is cut away, so

as to permit the cam E to force down the upper plunger, and with it the rods J Two dies M and M" are provided, the die M being located above the plunger G and the die M being located beneath the plunger L, and within these dies the respective plungers compress the material to form the asphalt blocks. The mold or die M is not in contact with the top of the guide G, but is separated from the same a distance equal to the thickness of a fced-slide N, which can slide horizontally that is, transversely to the direction of movement to the plunger G -on a table formed by the top surface of the uide G. A similar feed-slide N is-mountcr to reciprocate horizontally on the table formed by the top of the die or me] d M. A double anvil O,fitting within the dies or molds M and M, is mounted between them in such a manner that it can ice reciprocalerl vertically or moved. up and. dawn, and "this anvil U is provided tl'i lateral stops Q for the purpose? of liinibi 11g its move-n1?

The ening Q is filled with asphalt mixture. s the shaft D continues to rotate in the direction of the arrow its cam E forces up the lower plunger G, whereby the charge of asphalt in the lower feedslide N is forced up and out of this feed-slide and into the lower die M, and this charge forces upward the anvil 0 until its shoulders 0 rest against'the under side of the upper die M. By this movement of the plunger G the material pushed out of the lower feedslide N is compressed within the die M between the bottom of the anvil andthe upper end of the plunger G, and b the upward movement of the anvil O t e completed block (1 in the upper die M is pushed out of said die and u to the top 0t spid'die. During this time iihe materialh'asbeen. fed into the opening Q, of the feed-slide N, hich o ening Q is in line with the chute S. By tiiis time, also, thecam'E .has passed to the left of the roller F, Fig. 1, and the plunger G descends under the action of-its own weight. 1 By that time the cam has acted 'to rock the 2 5 rock-shaft P, and thereby the upper feedslide N is moved to the left and pushes the completed block resting onthe top' of the upper die M to the l'eft'upon a suitable conveyer belt. (Not shown.) Thereby the charge fed into the opening'Q of the slide N 'is moved under the plunger 'L, and thecharge in the opening1 Q .of the slide N is brought in line with t e feed-chute. At the I sametime that the upper slide N 'is moved to the left the lower feed-slide N is moved to the right, so that its opening will be in line with the feed-chute,'and a charge of asphalt is fed into this lower feed-slide N. The feed- "slides then remain at rest for a time, and the 4ojcam E acts on the lower roller F and forces i 1 ,down the upper plunger L which forces the 'char e from the opening Q of the slide N, whic o ening is now in line with the upper die M, ownward and compresses this charge in the die M and upon the upper end of they anvil O, and at the same time the anvil O is forced downward until its stops 0' rest on 1 ;the {top of the lower die M. Thereby the 'cd npleted block made in the lower die M, as 59. described, is ejected from this "lower die by i the descending anvil 0 upon the table. 'for-Ined'by the top of the guide G. By this ti e the cam E has passed to the right of the ld iiier roller F and the cams K have raised jshe'upper plunger L into the osition shown in Fig. 1 and the rock-shaft has been ooerated in such a manner tie-to Skiff: the u per feedislide N to the right and t e lower" eedslide N tothe left, whereby the completed eto of the guide G has been moved in the le t and upon avconveyer-belt, (not shown and at the same time the upper feed-slide has again in the position shown in Fig. La

slide N is not used for making a b been moved to, the right, and all parts are- When the yokes T' are forced upward, their'lower cross-pieces press the latches T together until these cross-pieces are above the latches T, and then the latches snap outward and the bottom cross-pieces-of the 7' yokes rest upon and are supported by the straight top edges of the latches.

When the rods J -move downward, their pins T bear on the bottom cross-pieces of the yokes, and thereby the yokes are forced down and'pull down the anvil 0; but these bottom crossieces are still above the latches T. When t e latches T arrive at the blocks T, the prongs t engage the lower beveled edges of the-latches and press the latches toward each other and keep them 'in this position during the time the rodsJ rise and while the yokes are at rest, thus permitting the'latches T to pass up between the side shanks of the yoke and above the bottom cross-pieces of the same and into the positions shown in Fig. 2, and by the time these latches have passed above the bottom crosspieces the latches are released from the block and can spread. During the next upward movement of the yokes the, bottom crosspieoes again press the latches together and 1 pass into position above the latches, as previously described. It will thus be seen that for each rotation of the cam-shaft two blocks 5 are made, first one by the upper plunger and then one by the lower plunger, and that then the completed blocks are successively pushed out of t e path of the plungers by the feedslides, the feed-slides at the same timedelivering material for fresh blocks.

It should be noted that the material assing into the opening Q of the upper eedock in the upper die, but is only temporarily removed outof alinement with the column of material in the chute, so as to permit the opening Q being filled,- and this material in the opening Q is then again brought into alinement with the column of materi ti in the feed-chute to be gradually forced down into the lower feed-slide N. I

It shouldalso be noted that the anvil 0. acts as a double anvil-that is. each end acts as an anvil and each end. also acts as an ejector for ejecting the block madeandlcompressed upon: this end of, the anvil, In order thatthe ateri'al me be evenly! distributed in :th pening's'o "the feed-slides, the vertical exist) the conveyer-screw in the bottom part of the hopper is moved attrifie .tojone side of thecentralaxisbf the hopper in the, direction in which theff'e'ed slides conv'eythe material iromthe fch'ute to the dies.
