Letters Patent No. 72,015, dated December 10, 1867.

IMPROVED BRICK-MAGHINE.

To ALL wH'oM 1T MAY odNcEaN:

' Be it known that I, SAMUEL Grssmenn, of Allegheny City, in the county of Allegheny, and State of Pennsylvania, have invented a new and useful Improvement in Brick-Ma'chines; and I do hereby declare the following to be a full and correct description of the same, s'uiicient to enable others skilled in'the art to which my invention appertains to fullyu'nderstand and construct the same, reference being had to the accompanying t drawings, which make part of this specification, and in whicht Figure lis a plan or top view of my improved brick-machine.

Figure 2 is la bottom view of the same; and

Figure 3 is a sideelevation of the same, the hopper and knives not being shown.

Similar letters of reference indicate corresponding parts in the several figures.

The nature of my invention consists in a novel mechanism by means of which the moulds are automatically pushed up to` and under the hopper, one by one, to be filled, and are pushed along until-they are received at the vopposite end of the hopper. i

y A, in the drawings', may represent the cylindrical hopper, through the centre of which theshaft B passes. This shaft -is provided with a set of grinding-knives, C,'l1aving fa. thick rounded back and a thin edge, and set obliquely on the shaft 4so as to crush the clay between themselves and the stationary knives D, which are secured at one end to the inner side of the hopper, and at the other end to a sleeve on the shaft B, as shown in iig. 4. Between the vstationary knives D and the bottom E of the hopper A, is a'set of fillers, E, consisting of blades set obliquely-onthe shaft B, their -lower edges passing close over the bottom E of the hopper, which is provided with a square opening, e, which is not quite as wide as the moulds d, so as to prevent the clay which is pressed down in thed'moulds from scraping down the sand from their sides, 'which would be the case if the4 opening e were as wide as the moulds themselves. Gis the rollerway for the moulds, formed under the bottom plate of the' hopper, land consisting of the bottom b and the sides c.v 4For a distance under the hopper and under i the openinge, the sides and bottom of the roller-way G are exsected, and rollers g placed in the openings, which allow the moulds to pass along-more easily than if the bottom were a mere board, and also prevents the roller-way -G from being clogged up, any clay falling outside of the moulds being enabled to'fall through the openings between the rollers g. p The roller-way G extends on both sids of the hopper, 'and forms on one end a platform, H, with ,an extension, I, 'at right angles with the platform H. Each of these platforms husa slot, t and e', in which blooksj and c move. v Blockj serves to move the moulds d up to hopper andon to the platform H, and is Operated by means of an arm, Z, the free end of which is attached to alever, m, operated by means of a. pin, n, on the under side of a gear-wheel, o, on the shaft B. This wheel o gears with another wheel p, on a shaft,p, and gives motion to the block 7c by means of the 'crank-arm k', in such manner that whenever the block k is near the farthest end of the slot z', the block j is moved, by means of the pin n. on the wheel o and intermediate devices, the length of the'slot h, leaving thernould at the point wherey it is seized by the block c on its return motion, The blockj is held in position at the farthest end of the slot 7L, and is forced to resume this position every time the pin 'n has operated the lever m, by means ofthe spring m', attached at one end to the platform I, and at the other to the arm Z. The wheels o undp gear in such n, manner that the block]I will beoperated only when the block 7c is at the farthest end of the slot z', and a mould may lie-placed in front of the block j therefor, whenever this latter has returnedto'its normal condition, without regard to the position of the block k. This feature is illustrated in ig.- l. One mould has not yetv quite been pushed in bythe block 7c, but another isI already in position in front of block j to be operated upon.

It ,will be easilypunderstood that as the moulds are pushed along" by means of each other, their ends will be in continuous close contact with cach other und prevent any clay from falling between them, and thus clog up any part of the machinery, and should the personlwho places the moulds on the platform I, in front of block j, miss one operation ofthe blocks j, k, without placing a mould, no clay will be wasted, as the moulds already in the roller-way G will remain in place, as the block 7c only moves as far as the bottom plate E of the hopper.v

i' In brick-machines in which endless belts are used to convey the moulds under the hopper, much troubleis experienced by waste of clay and clogging up of the machinery, when the moulds are not placed with the utmost care and eontiguensy on the endless belt, for if the operator should emit to piace a. mould close to the preceding one, the clay from the hopper vwili fall between them and on the belt.

Having thus described my invention, whatclaim as new, sind desire to secure by Letters Patent, is-

1. The device for moving the mould, on to" the rolier-wny G, consisting of the erm l, held bynsp'ring, m-, lever m, pin n, on the gear-wheel o, and block j, moving in the slot substantially as described.

2. The device for moving'the moulds under the hopper, consisting of the geur-wheelp, operated bythegear-wheelo, arm 1c', and block k, moving in the siot z', substantially as described.

3. In combination with the above, I 4claim the gear-wheel o, shaft B, grinding-*knives C, stationary knives D, and llers F, in the hopper A, s nbstantially as and for the pdrposes described.

' 4. '.lhe roller-way G, ipeovided with openings and rollers g and g', substantially as and for the pnipcvseV described.

The above specification of'my improvement-in brick-machines, igned this 26th day of September, y1867.4
