To all whom it Hwy concern.-

Be it known that I, JOHN O. TITUS, of New Bremen,Auglaize county, Ohio, have invented certain new and useful Improvements inBrick or Tile Machines, of which the following is a specication.

This invention pertains to that class of brick or tile machines in which the clay is forced ont of a pug-cylinder into a plunger-chamber by means of a feed-wing on the pug-shaft, the

clay being forced out of the chamber through a die by the action of a plunger; and the nature of the improvements will be readily nnderstood from the following description, taken in connection with the accompanying drawings, in which- Figure l is a vertical longitudinal section of a machine exemplifying my improvements; Fig. 2, a horizontal section of the same; Fig. 3,

a horizontal section of the pug-cylinder, and

Fig. 4 an edge view of the feed-wing.

In the drawings, A indicates the usual pugcylinder; B, the pug-shaft disposedy centrally therein and adapted to be rotated by any of the usual means; C, the plunger-chamber underneath the pug-mill and arranged to receive the clay therefrom; D, the opening in the floor of the plug-mill, through which the clay goes from the pug-mill to the plunger-chamber; E, the die forming the end wall to the plunger-chamber and ,through which itis the duty of the plunger to force the clay to form the tile o'r brick, the intention being to employ any desired or suitable or usual form of die; F, the feed-wing secured to and carried around by the pug-shaft, this feed-wing having its under surface sloped upwardly and forwardly from near the floor of the pug-cylinder, the length of the feed-wing being in excess of the length of the discharge-openingD; G, the plunger fitted to reciprocate in the plunger-chamber to and from the die and past the opening D, the exemplilication showing this plunger as of skeleton box form, with the pugshaft passing down through it; II, a pressurecylinder for steam or water or other pressure fluid, this cylinder being shown in the exemplification as arranged tandem to the plungerchamber; J, the piston of the pressure-cylinder 5 K, the piston-rod connecting the pressurepiston and the plunger; L, the valve of the pressure-cylinder, (shown as an ordinaryslidevalve,) the arrangement of pressure-cylinder and valve being the same as in ordinary slidevalve steam-engines; M, an eccentric driven by the pugshaft,the exemplication showing vthe eccentric as being secured directly to the pug-shaft; N, the eccentric-rod; O, the valvestem; P, a bell-crank lever pivoted to the plunger-chamber and having one of its arms engaged by the eccentric-rod and the'other arm connected with the valve-stem; Q,a segmental flange projecting upwardly from the floor ofthe pug-mill just inwardof the discharge-opening D, this flange forming an inner fence to the discharge-opening, between which fence and the wall of the pug-mill the feed-wing F travels, the arm which attaches the feed-win g to the pug-shaf t being disposed high enough to clear the top of this fence; R, an eccentric or volute arm mounted upon the arm of the feed-wing, this eccentric-arm presenting outwardly a wall about opposite the feed-wing and at such distance from the pugshaft that its extremity will just clear the inner surface of the fence Q; and S, a spur-gear of the pug-shaft, exemplifyin g ordinary means for use in connection with the driving of the pug-shaft.

As the pug-shaft revolves the feed-wing is carried around in the pug-cylinder near the floor thereof, passing between the cylinderwall and the fence and over the dischargeopening D, forcing down into the plungerchamber the clay that is over the opening. The eccentric-arm R forces the clay outwardly from the center and into the path of the feedwing and forces it into the space behind the fence over the discharge-opening. The clay is free to pass back to the center of the pugcylinder behind the eccentric-arm, except at the fence, where it is retained till the feedwing forces it through the discharge-opening. The clay being at liberty to return to the center, except at the fence, relieves the feed-wing of unnecessary vertical strain while passing around to the discharge-opening.' Clay behind the fence becomes dammed up by clay in advance of it which has not yet been able to move to the center of the pug-mill, and consequently when the feed-wing attacks the clay behind the fence the clay finds its only free escape through the discharge-opening.

The valve-gear of the pressure-cylinder is operated directly from the pug-shaft, and consequently the valve must move in unison with the pug-shaft. At each rotation of the pug-shaft the valve is moved and steam aclmitted behind the piston and the plunger forced forward past the discharge-opening D, the clay being thereby forced out through the die, the pug-shaft continuing to turn, then moving the valve the other Way and causing the piston and plunger to retreat and permit the plunger-chamber to receive a neu7 charge of clay from the pug-mill.

I claim as iny invention- 1. In a brick or lrile machine, the combination, substantially as set forth, of a pug-mill having a discharge-opening in its ioor, a fence projecting upwardly from said ioor near the inner margin of the discharge-opening, an upwardly and forwardly sloping feed-Wing carried by the pugshaft in a path over the discharge-opening, anda volute or eccentric arm carried by the pug-shaft at the level of the feed-wing.

2. In a brick or tile machine, the combination, substantially as set forth, of a plungerchamber, a die, a plunger Working in the plunger-chamber, a pressure-cylinder having a piston connected with said plunger, a valve for said cylinder, a pug-mill arranged to discharge into said pressure-cylinder and having a pug-shaft, and valve-gearing disconnected from said plunger and connecting said pug-shaft and valve, whereby the valve is positively moved. in unison with the revolutions of the pu f-shaft.
