BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No.

309,549, dated December 28, 1884:.

Application filed May 19. 189 (N0 mmlell To all ID/71107111 it mwy calmer/1 1 Be it known that I, Josnrn. J. KULAGE, of St. Louis, Missouri, havemade a new and useful Improvement in Brick-Machines, of which the following is a full, clear, and exact description, reference being drawings, making part of this, specification, in which Figurel is a side elevation of theimproved machine; Fig. 2, a vertical longitudinal see lion; Fig. 3, a plan; Fig. 4, an end elevation, partly broken away, looking toward the delivery end of the machine; Fig; a horizontal section on theline 5 5 of Fig. 4.; Fig. 6, a section on the line 6 6 of Figi 4; Fig. 7, a vertical section on the line 7 7 of Fig. 4-; Fig.8, a plan of the cross-hcad, and Fig. 9-an elevation of the catch used in preventing the back action of the toggle and plunger.

The same letters of reference denote the same parts.

The present invention is dry-clay machines.

The improvement relates to the mechanism for imparting the movement to the plunger-s, to the construction of the toggle, to the operation of the plungers, and to various minor points hereinafter described, and designated in the claims.

A A represent two gear-wheels, attached, respectively, to the shafts 131;. The shaft 1, is the driving-shaft ofthe machine. It is pro vided with the pinions A A", which engage, respectively, with the wheels A A. The shafts B Bturnin suitable bearings, M, in the frame 0. The wheels A A are united by means of the wrist-pin l), and in effect form a double crank for operating the pitman 1D. The pitman at its forward end. is connected with the eross-hcad F, work in the slides G G. i

H represent links which at one end are pivoted to the cross-head at h h, and at the other end are jointed to the toggles l I. The toggles turn on the bearings M, respectively, in the forward end of the l'ramc O, as shown more distinctly in Figs. 1, 2. By means of the links 4; i the toggles are jointed to-the plungers J J, respectively. The plungersarc adapted to work upward and downward in the guides K K, and to operate in connection an improvcnumtin had to the annexed which is adapted to with the mohl-lran1e L. The mold-frame has cells or molds Z Z Z Z, in which the bricks are formed, and is arranged between the plungers. The lower plunger, J, has sub-plungers jj which are adapted to work up ward through the molds Z Z Z Z, and the upper plunger, J, is adapted to work downward, its

- sub-plungcrs j j 7' j passing downward into the molds.

The operation of the machine is as follows: As the wheels A A in their rotation operate to thrust the pitman to its forward limit, and thereby withdraw the plungcrs, respect ely,

downward and upward to open the molds, a charger. M, is caused to move forward beneath the hopper N, and thereby fill the molds with clay. The chargcris actuated as follows: Two rods, m on, lead from the charger and respectively 011 each side of the pitman, and at their rear ends are jointcal to the bell-crank levers m m, respectively. These lovers in m are journaled, respectively, at 7JL 77l/ lll the frame 0, and the arm m of the toggle is adapted to be moved by means of the guide a which. is attached to the wheel A, and whose peculiar shape is shown in Figs. 2-that is, each wheel A and A. has a guide, a", which operates the bell-crank lever belonging to it. The continued rotation of the wheels A A causes the bell-crank levers to be l turned on their our- I! nals, and the charger in consequence to be moved forward and backward, as described, and so as to deposit the clay in the molds. As the charger moves forward its front end, in", pushes the bricks previously :l'ormed oft onto a suitable receiving-table. The upper plunger is passed by the charger in its forward movement by reason of the end m being made sui'li cientl y low. The sides mmol:' the charger are made higher. During the charging of the molds the pl ungers are stationary. This is accomplished by elongating the strap 6 of the pitman E, so that while the wheels A A are acting upon the bell-crank levers they do not act to move the pitman. Alter charging the molds the wheels A A not again upon the pitman, and cause the pitinau to be drawn baclnvard, and the plungers, through thclinks i H H and toggles I1, to be moved toward each other, the sub-plungers of the lower plunger entering the molds, or rather passing upward in the molds, (as thelowersub-plungers never entirely drop out of the molds,) and the upper sub-plungers passing downward into the molds and suitably thereinto, to cause the clay to be properly pressed to form the bricks. The wheels A A continuing to act on the plungers, the upper plunger is withdrawn upward above the molds, and in its upward movement the upper plungerlil'ts the lower plunger with it, and as follows: The lower plunger is provided with the snap-hoolcsNN. These hooks, as the bricks are eoxinpressed, engage with the hooks or shoulders O O, upon the upper plunger, and the two plungers are thereby locked together, so that the rising of the upper plunger causes the lower plunger to be lifted out of its bearings Vi" in the link 13, Fig. 7. This lastdescribed upward movement of the lower plungercauscs its sub-plungers to be projected sufficiently upward through the mold to eject the bricks therefrom. The bricks are now upheld upon the lower sub-plungers and are ready to be discharged from the machine. The charger now comes forward, as described, and pushes the bricks from off the sub-plungers and out of the field of the plungers. As the charger reaches its forward limit its beveled sides m m, Fig. heneountcr and cause the snap-hooks NN to be disei'igagedd'rom thehooks O O. The lower plunger then drops, but, and just before encountering its bearings 17 '6, its fall is arrested by the chains I 1-, which at one end are attached to the machine-frame and at the other end to the lower plunger. At their upper ends or at other suitable point the chains are adapted to cushion the fall of the plunger, as by means 01. the rubber washers p p, interposed. between the nuts 1) and the chainsthat is, the chain at its upper end is provided with a bolt, pflwhich passes through the bearingp and washer p, and above the washer is provided with the nut p. 13y suitably adjustingthc nut upon the bolt the chain can be adjusted to allow the plunger to drop as desired. The weight of the toggles is liable to be overcome by that of the plungers, and, in

consequence, what may be styled a back-action of the cross-head, 860., may occur. To insure the holding of these parts in their places until it is desired to have them move, I employ the spring hook or bar Q, Figs. 1, 2, which operates in connection with the lug g on the lower toggle. The bar Q operates to sustain the free end of the toggle until the pitman, in its ,rearward movement, encounters the bevel qof the bar. The bar is then dislodged from beneath the toggle, allowing the toggle to move.
