SPECIFICATION forming part of Letters Patent No.'443,321, dated December 23, 1890.

Application filed y 22, 1890. Serial No. 359,533. (No model.)

To all whom it may concern:

Be it known that I, GEORGE KING, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in a press; and it consists in certain features of construction and in combination of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis an end elevation, partly in section. Fig. .2 is a side elevation, partly in section. Fig. 3 is a plan of the table and attachments. Fig. 4 is a plan of the yoke that operates the follower. Fig. 5 is a plan of the rock-shaft and attachments. Figs. 6 and 7 are, respectively, plan and elevation of a crank-shaft, the same being a modification, hereinafter described. The press shown in the drawings is adapted to press rectangular bricks that have been molded or dried or partially dried; but the press, by changing, for instance, the form of the die or cup and plunger, may be adapted to press various shaped tiles or other material.

A represents the supporting-frame, that is preferably a cast-iron square or rectangular hollow column, cast open at top and bottom, the column being provided with suitable side openings A to give access to the internal mechanism. The column near the bottom has side pockets A open top and bottom, for purposes here nafter mentioned. The column at the rear has an opening A for accommodating pitman F. This form of supportingframe is not essential, but is compact, strong,

and convenient, and hence is preferred.

B is a table fastened on top the column or other supporting-frame. The table at the center thereof has a depending flan ge B, that extends down inside the column or frame, this flange inclosin g a chamber B that serves as a die, mold, or cup in which thebrlck, tile, or other material is pressed, and hence this chamber and the plunger that operates therein may be rectangular, as shown, or may be square or round,or of any other form, according to circumstances. We will suppose, how ever, that chamber 13 is rectangular, as shown,and is adapted to receive an ordinary unburnt brick.

C is a reciprocating plunger adapted to fit the die or cup, this plunger constituting a part of and preferably being integral with cross-head O. V

D is the bottom member of the die, cup, or mold, and may be cast integral with flange B, or may be cast separate and then bolted to the under side of this flange, as shown, ac cording to circumstances. If this die is round, so that it can be bored, or if the die is to be lined with steel plates backed by soft metal, as is frequently done in such cases, member D could be cast integral with flange B. In other cases member D had better be cast separate for convenience in dressing the die, capscrew d being shown for securing this mem her to flange B.

EE are toggle-arms. The upper arm E has a rounded upper end that fits in a corresponding groove in the bottomof member D. This toggle-arm has also trunnions e, and member D is provided with caps or half-boxes (Z d'for engaging the lower side of these trunnions to hold the toggles suspended, with the upper toggle-arm always in contact with member D. Gaps d are secured to member D by suitable cap-screws d. The lower toggle-arm E has large strong trunnions 6, one of which is shown more clearly at the left hand in Fig. 1.

The two toggle-arms are pivotally connected by a strong bolt or pin e This pin or bolt also passes loosely through a hole in the forward end of pitman F.

G G are the side bars that connect the lower toggle-arm with the cross-head. These side bars have rectangular heads G, pierced laterally for receiving with an easy fit trunnions e, these heads fitting loosely in pockets A aforesaid. Above the heads the side bars are preferably round rods, the upper sections thereof being screw-threaded and provided with nutsg above the cross-head, and provided with jam-nuts g, engaging the under side of the cross-head, the latter having suitable holes cored therein for receiving the screw-threaded sections of these side bars. With such construction the cross-head may be adjusted vertically by manipulating these nuts, after which by tightening the nuts the cross-head is rigidly secured to the side bars. To save dressing the inside of pockets A the latter are constructed considerably larger internally than heads G, and gibs care provided, and adj Listing-screws a, as shown more clearly in Fig. 2, these gibs being simply fiat plates of metal with holes drilled therein to receive the reduced ends of the set-screws. Near the upper end of the column are boxes a through which the side arms respectively reciprocate.

II is a rock-shaft journaled in boxes or, this rock-shaft having a socket II for inserting a hand-lever 11 the latter being usually of wood. Shaft II has rock-arms 72 71, provided with a removable wrist-pin 7b, the latter having an easy fit in a lateral hole at the rearward end of pitman F.

I is a follower consisting of a metal plate nicely fitting inside of the die, this follower being connected by rods I with yoke i, rods 1 passing loosely through holes in member I). Yoke i has forked ends i, (shown more clearly in Fig. 4,) the prongs whereof pass astride bars G. Thelatter are provided with adjustable collars g secured to the side bars preferably by set-screws. (Shown at 9".) \Vith the upstroke of the side bars, collars engage the under side of the yoke, whereby the yoke and follower I are elevated to lift the brick or other material from the die, and by means of stop K engaging the opposing end of member ll and by means of adjustingcollars the follower is lifted to a position ilush with the top surface of the table. An adjustable stop Ii is provided, this stop being adapted to engage thehanddever, when on the downstrokc of the latter the toggle-arms are brought in line. \Vith the hand-leverin the position shown in dotted lines, Fig. 2, the toggle-arms are deflected, as shown, whereby the plunger is elevated the necessary dis tance above the table to admit of removing the bricks or other material.

L is a plate of metal adapted to slide on the table, the latter having upwardly-pro jeetin g ribs 7) that embrace and serve as guides for plate L. To the table are secured steps 1) IF that limit the end movement of plate L. Plate L is provided with openings L L located, say, an inch or two apart, and each opening corresponds in plan with the chamber of the die. Plate L is provided with handles t Z for sliding the plate endwise, the relation of parts being such that when plate L engages step 1) opening L is directly over the die, and with the plate engaging stop 1) opening L is over and registers with the die.

In the position shown in Fig. 3 a brick is supposed to be in the die bein pressed. Meantime the brick that has already been pressed is supposed to be removed from opening L and another brick substituted. On the next upstroke of the plunger the brick in the die is raised by the follower to a position flush with the table, and plate L is then moved toward the left hand until it engages stop I)", by which movement the pressed brick is slid along the table toward the left hand from under the plunger, and the brick in opening L is by the same operation brought to a position over the die. \Vith the next stroke of the machine plate L is reversed to the place of beginning, and so on, the bricks being changed while the machine is operating upon the brick in the die. The one workman operates the hand-lever and the other workman removes and supplies the bricks. If it is desired to operate the press by power, a pitman can be attached to the hand-lever or crank M, and pitman in may be substituted in place of the rock-shaft and pitman F, (shown,) and a driving pitman or pulley may be mounted on the overhanging ends of such crank-shaft.

\Vhat I claim is- 1. In a press, the combination, with a stationary die or mold and a reciprocating plunger adapted to operate in connection with said die or mold, of a suspended toggle adapted to pivotally bear against the bottom member of the stationary die or mold, the other extreme of the toggle being operatively connected with the plunger for operating the latter, substantially as set forth.
