BRICK AND VTILE IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 252,636, dated January 24, 1882. Application filed November 19, 1851. (No model.) Patented in Canada March 13, 1880.

To all Iwhom it may concern Be it known that I, AUGUSTUS VEHLANN, a citizen ofthe Dominion of Canada, residing at Aldborough, in the county of Elgin and Province of Ontario, have invented certain new and useful Imllrovements in Brick and Tile Machines; and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being` had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a sectional view of a machine constructed in accordance with my invention, and showing the cutting table or carriage in elevation. Fig. 2 is a top plan view of the hollow base. Fig. 3 isa horizontal section thereof, and Fig. 4 is a perspective view ofthe adjustable cutting table or carriage.

The present invention has relation to certain new and useful improvements in brick and tile machines; and the objects thereof are to ccnstruct a machine that will prove strong and ldurable and effective in its operation as well as easily operated and not liabfe to get out of order, also insuring the perfect and effectual working of the clay and the producing ot the brick or tileuith comparatively little labor and trouble and with little or no waste ot' the clay. These several objects I attain by the construction, substantially as shown in the drawings and hereinafter described.

In the accom panyingdrawings, A represents an upright hollow cylinder, which may either be constructed in a single piece of metal or of two separate sections, as shown, and afterward bolted or otherwise connected together. At the top of the cylinder A is an arch or bail, a, passing diametrically across the opening in the cylinder and having its ends rigidly connected to the rim thereof. Through the arch or bail a passes a square-formed shaft, b, having connected to, it above and below the arch or'bail by suitable set-screws, c, collars d. The shaft b extends down and through the cylinder A, and has connected to it by set-screws c a series of knives or cutters, B. In place of being formed of cast-iron, the shaft is coilstructed of wrought-iron, thereby obtaining greater strength and durability.

The knives or cutters B, as will be sten, are

double instead of single, and have a square hole through their center to admit of their being slipped over the end of the shalt b, and held in position thereon by the set-screw e, as heretofore described. This enables the knives or entiers to be removed when required or adjusted on the shaft to vary the distance. between them when a. greater or less number is used, the setescrews being much more effi ctivc in connection with the square form ot' shalt than the ordinary keys now in use.

A sleevtf, may be employed to fit within the opening in the arch or bail a, which opening is ofcircular form, or round, while the opening in the sleeve is vsquare to conform lo the shape of the shaft b, and a similar sleeve, g, near the lower end ot' the shaft, said sleeves serving' as journals, thus enabling them to be removed when worn and replaced by others.

The upright c vlinder A is connected in any suitable manner to a hollow base, O, into which the lower end of the shaft b projects, and is formed with a short journal, 7L, resting in' a step, i, at the bottom of the hollow base.

The sleeve g has its bearing in a erosspiece, 7c, which forms a pait of the top of the hollow base G, and below this sleeve the shaft b passes through a rectangular/cap or plate, t. This plate covers au opening in the top of a plua ger, D, located within the hollow base C, and operated by an eccentric, E, rigidly connected to the shaft b, its periphery bearing upon the faces of friction-rollers F, journaled within the plunger, as shown in Figs. 1 and 3. The plunger D forces alternately the clay through suitable molds, G, removably connected to doors Il, hinged to each end of the hollow base (l.

To admitof the plunger D moving backward and forward within the hollow base O, it is formed7 with an elongated opening, m, through which the shaft b passes, said opening being covered by the plate or cap l, as before described, so as to prevent the clay from getting into the interior of the plunger and affecting the working parts ofthe machine. The eccentric E, which is of cast-iron, revolves against the f1 iction-rollers F, which causes the plunger D to have imparted to it. a horizontally-reciprocating motion to force the clay ont through the molds in forming the brick or tile.

The above-described means of opera-ting the IOO plunger is considered of great importance, as the crank ordinarily in use for this purpose works against the side of the plunger, and the wrist of said crank necessarily wears very rapidly and lessens the quantity of clay pushed or forced out at each stroke, whereas the eccentric E gives both uniformity in motion, quantity of clay expressed, and lightness of draft. The doors II, as will be seen. are hinged instead of being bolted, thereby facilitating the Y operation ot' changing the molds, and each doorat its top has a water tap or taps, a, for the puipose of giving ,a suiicient supply ot' water to each mold in use, thereby obviating the necessity ot' having the base of the machine on a water-level.

The plunger D at each end is provided with two valves` o, to admit air on its receding motion, and the molds G, when found necessary, are provided with perfbrating-bolts p, connected to cross-bars q.

To each end of the hollow base C is connerted a cutting table or carriage; but in the drawings I have simply shown one suoli, which is considered soffici' nt to describe 'their construction.

The table proper, as represented at I-or in other words, a carriage-is provided with suitable truck or grooved wheels, r, which rideupon tracks s, secured Ato a frame, K, connected in any suitable manner to the end of the hollow base C. The carriagel has connected to the sides thereof a. series of horizontal rollers,t, arranged parallel with each other, which together form the bed ot' the carriage to receive the clay. The carriage I is provided with a pivoted stop, L, so as to prevent the clay from being pushed too t'ar beyond the eutting-wires u, thereby rendering it unnecessary to return portions of brick or tile to the ma chine to be wrought over again. The wires u pass between the rollers t, and are connected at their upper end to a horizontal bar, w, and

]. In a brick or tile machine, the square shaft b, passing through correspondinglyformed openings in journals f g, at the upper and lower ends thereot',and having removably and adjustably connected to it the knives or cutters B, the same having square openings through which the shaft passes, and held thereon by set-screws e, substantially as and for the purpose set forth.

2. Ina brick or tile machine, the combination, with the shaft b, carrying knives or eutters B, and eccentric E, of the plunger D, provided with friction-rollers F, and valves 0,substautially as and t'or the purpose specified.

3. In a brick or lile machine, the plunger D, having air-valves o, elongated opening m, and friction-rollers F, in combination with the shaft b, carrying eccentric E, and the cap or plate l, substantially as and for the purpose set forth.

4. In a brick or tile inachine,the cylinderA, shaft b, knives or cutters B, eccentric E, in combination with the hollow base C, provided with hinged doors H and molds G, and the plunger D, constructed as described, and having the friction-rollers F, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my nalne in the presence of two witnesses.

AUGUSTUS WEHLANN.
