SPECIFICATION forming part of Letters Patent No. 347,136, dated August 10, 1886.

Application filed February 24, 1886. Serial No. 193,021. (No model.)

To all whom it may concern..-

Be it known that I, WILLIAM E. TALLOO'I, of Groton Landing, in the county of \Vestchester and State of New York, have invented a new and useful Improvement in Brick-Machines, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the'figures.

Figure 1 is a side elevation of my improved brick-machine. vation of the same. Fig. 3 is a sectional front elevation of themold-table and the mold-driving frame, taken through the line as m, Fig. 2. Fig. 4 is a bottom view of the same, parts bethe mud-cylinder and the wipers, the vertical shaft being shown in section. Fig. 6 is a side elevation, partly in section, of a part of the vertical shaft, and showing the guard-collar in section.

The object of this invention is to improve the construction of the brick-machines for which Letters Patent No. 237 ,636 were issued February 8, 1881,Willian1 E. Tallcot, inventor, in such a manner as to make them more convenient in use and more reliable in operation.

The invention consists in the constructionand combination of various parts'of the machine, as will be hereinafter fully described.

A represents the base-frame of the machine, the upper forward part of which projects and has a platform, 13, attached to its top, to form a table to receive the molds and support them while being filled.

To the top of the rear part of the frame A is attached the semi-cylindrical base 0, to which is attached the lower end of the mud-cylinder D. To the opposite sides of the upper end of the mud-cylinder D are attached the ends of an arched cross-bar, E, in the center of which is formed a bearing to receive the upper end of the verticalshaft F, or 'a journal formed upon the said upper end. The upper end of the journal of the shaft F is covered 'with a cap, G, to prevent mud from getting into the bearing and wearingthe said bearing andthe shaft-journal.

The lower part of the shaft F revolves in a bearing, H, secured to the base 0, and which Fig. 2 is a sectional side elefreely into thelower partof the said cylinder.

To the shaft F just above the collar J are attached or upon it arejournaled dovetailed ribs L, which fit into dovetailed grooves M in the shoes M, so as to connect the said shoes securely to the said shaft. The outer surfaces of the shoes M are curved, and to them are secured by bolts N the curved wings or wiper plates 0 by which the mud is pushed through an opening, P, in the lower part of the forward side of the cylinder D into the press-box Q secured to the forward side of the said cylinder. By this construction the wipers will be independent of each other and can be readily detached from the shaft, and thewiper-plates can be readily detached from their shoes and replaced with new plates. If desired, the wiper-plates and their shoes can be made in one piece; but I prefer the construction first described, as it allows the wiper-plates to be made of steel and their shoes of cast-iron or steel. In the bottom of the press-box Q is formed an opening, through which the mud is forced down into the molds by the plunger It. The plunger It, upon its ends and forward side, is provided with a packing, 2, the upper and lower edges of which are beveled, and which is held out against the inner surface of the press-box Q by spiral springs 3,placed in recesses in the said plunger, and which is designed to prevent the mud from working up between the said plunger and the ends and side of the said press-box. Upon the upper side of the end parts of the plunger R are formed keepers S, through which is passed a bar, T. The bar T passes through vertical slots in the upper parts of the ends of the press-box Q, and to the ends of the said bar T are pivoted, by pins or other suit able means, the forked upper ends of the connecting-bars U. The lower ends of the connecting-bars U are pivoted to the forward ends of the arms V, the rear ends of which are secured to a shaft, \V. The shaft XV rocks in hearings in the base-frame A, and to one of its ends is secured at its angle the three-armed lever X. The upper arm of the three-armed lever X is made short, is slotted, and to it is pivoted the lever Y. To the rear ends of the levers X Y are pivoted rollers Z, which are struck successively by the cam a, secured to the drive-shaft b. The drive-shaft b revolves in hearings in the base-frame A, and power can be applied to it by a pulley and belt, or other suitable means. \Vith this construction, as the cam a strikes the roller Z of the lever Y, the levers X Y and the arms V will be vibrated to drawihe plunger R downward and force the mud out of the press-box Q, and into the molds. As the cam a strikes the roller Z of the lever X, the levers Y X and the arms V will be vibrated to force the plunger 1 upward, to allow more mud to enter the pressbox Q.

To the forward end of the levcrX is pivoted the lower end of the bar 0, in the forward edge of which are formed rceessesd, to receive the lag 0, formed upon or attached to the side of the forward end of the lever Y, so that by adjusting the catch-bar c, to change the lug c from one to another of the recesses d, the rear ends of the lovers X Y will be adjusted at a greater or less distance apart, to give a less or greater vibration to the levers X Y and the arms Y, and a less or greater movement to the plunger 2, as may be required.

The upper end of the catch-bar c is extended forward, as shown in Fig. 1, so that it can be conveniently reached and operated by the attendant standing in front of the machine. The lower end of the catch-bar c is extended a little below its pivot, and. has teethf formed upon it, with which engages a spring-pawl, g, secured to the lever X, to hold the catch-bar c in gear with the lever Y when the machine is at work.

To the drive-shaft Z: is attached alarge beveled gear-wheel, h, the teeth of which mesh into the teeth of the large beveled gear-wheel t, attached to the lower end of the vertical shaft 1 so that the said vertical shalt will be revolved from the said drive-shaft.

j is a frame, which is placed just below the platform I, and the side edges of which slide in grooves in the inner sides of the side top bars of the frame A. To theupper side of the rear end of the sliding frame j are attached the rear ends of two bars, 7.1, which are made with an upward curve or offset, I, at or near their rear ends, to raise the said bars above the level of the platform I The bars 7; pass through holes in the front wall of the semi cylindrical base (1, and to their forward ends is attached a cross-bar, 111, so that the mold will, be pushed squarely beneath the press-box by the forward movement of the said bars 7:. Upon the forward side of the cross-bar m, near one end, is formed, or to it is attached, a lug,

a, to serve as a stop to the mold when being pushed into place before the said cross-bar. \Vith this construction the part of the front wall of the base 0 below the push-bars 7.: will prevent the sand falling upon the platform or table 15 from falling from the rear end of. the said platform, and coming in contact with and wearing the bearings of the sliding frame.

The sliding framej is pushed forward and back by the cams 0 1), attached to the vertical shaft F just above the gear-wheel The cam p operates against the downwardly-projecting flange q, attached to the rear end of the frame j, to force the said frame back.

To force the sliding frame j forward. the cam 0 operates against the roller 0-, pivoted to the rear end of the bar or interior frame, 8, which slides in a way in the forward middle part of the said framej. The forward end of the bar a, when the said bar is in position for the roller 0' to be operated upon by the cam o, rests against a shoulder, t, formed upon the rear end of the lover a, the said rear end of which is pivoted to snpportso, attached to the sliding framej. The forward end of thelever a is provided with a catch, 10, to engage with a spring-latch, 41?, attached to the forward part of the frame], and which is made of sufficient strength to hold the said lever it against the forward push of the sliding bar a under ordinary circumstances; but should the mold in its forward movement encounter a stone or other obstruction the spring-latch a will yield and allow the catch-lever u to drop and withdraw the shoulder from the end of the sliding bar s, so that the said sliding bar moves forward, carrying the roller 1- out of reach of the cam 0, and therefore the sliding frame j and the push-bars 7.: will not be operated by the revolution of the shaft F and its cams o p. The catch-lever u is also provided with a handle, y for convenience in raising it into engagement with the spring-latch :0, and with a stop, a, to strike against the framej, andlimit the upward movement of the said catcli lever.

\Vhen the obstruction has been removed the sliding bar 5 is pushed back into such a position that the catch-lever a can be raised into engagement with the spring-latch m by means of a rod, Z, attached to the forward end of the sliding bar 8, and projecting into such a position that it can be readily reached and operated by an attendant standing in front of the machine.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a brick-mac]1ine,the combination,with the drive-shaft I), the rock-shaft \V, the plunger R, and the bars U and arms Y, connecting the said rock-shaft and plunger, of the cam (t, attached to the drive-shaft, and the levers XY, provided with rollers Z at their rear ends, and connected with each other and the rockshaft, substantially as herein shown and described.

2. Inabriek-maehine,the c0mbi11ation,with

ICC

the drive-shaft b, the rock-shaft W, the plunger R, the bars U, and arms V, connecting the rock-shaft and plunger, the cam a, attached to the drive-shaft, and the levers X Y, connected with the rock-shaft, f the pivoted bar 0, provided with recesses d, and a holding mechanism and the lug e, engaged by the said bar, substantially as herein shown and described, whereby the said levers can be readily adj usted to regulate the throw of the plunger, as

set forth.

3. In a brick-machine,the combination,with the frame A and the vertical shaft F and its driving mechanism, of the cams 0 1), attached to the said shaft, the sliding frame j, having 7 roller 1', and flange q, the push-bars k, attached to the sliding frame, and the cross-bar m, at-

ure under ordinary circumstances, but will yield and be thrown out of gear should an obstruction occur, as set forth.

5. In a brick-machine, the method of protecting the sliding frame j from sand, which consists in making the push-bars 70 with an upward offset, and passing them through holes in the wall at the rear end of the mold-table, whereby the sand will be prevented from falling off the rear end of the said mold-table, as set forth.'

6. In a brick-machine,the combination,with the mud-cylinder D and the vertical shaft F, having dovetailed ribs L, of the wipers M 0, having dovetailed grooves M, substantially as herein shown and described, whereby the wipers will be secured to the said shaft detach ably, as set forth.
