Letters Patent No. 98,547, dated January 4, 1870.

IMPROVEMENT IN BRICK-MACHINES.

The Schedule referred to in these Letters Patent and making part, of the same To all ul'hom it may concern Be it known that we, THOMAS BISHOP and DANIEL AGNEW, of Vincennes, in the county of KnoX,and in the State of Indiana, have invented .certain new and useful Improvements in Brick-Machines; and dohereby declare that the following is a full, clear, and lexact descriptiouthereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of our inventionconsists lin the construction and general arrangemeutof a brink-inachine2 and its moulds.

In order to enable others skilled in the art to which our invention appertains, to make and use the same, we will now proceed to describe its construction Vand operation, referring to the annexed drawings, in Which- Figure l chine; y

Figure 2 is a bottom View of the same;

Figure 3 is aV plan view of i the mould;

Figure 4 is an end view of the same; and Figure 5 isa vertical cross-section, taken `through line :c z, iig. 3.

Figure 6 is an enlarged vertical cross-section of the die-plate. Y

Figure 7 is a side view of the adjustable bars upon which the'inner end of the mould-rack rests.

Figure 8 is a side view of the presser-wings.

' Figure 9 is a plan view of one ofthe cutters or workers, and

Figure 10 is a cross-section of the same, taken through line y y, fig. 9. y

A represents the receptacle for the mud, or mud-V gum, as it is generally called, rest-ing upon wheels B B, so lthat it can be moved readily to any place desired.- In thedrawings we have represented the mudgum as being square, but in a full-sized machine we intend to lill the front corners to a circle, to fit the is a perspective view of the brick-mapress-wings, which will prevent the mud from squeezing up, andwill force it into the mould.

At the front side, in the bottom ofthe mud-gum A, is placed thedic-plate C, the front edge of the under side of `which is bevelled, as shown -in iig. 6, at a, so that on the principle of a wedge it will press the gravel-stones in the clay into the brick, and will thus y, prevent the breaking of the mould by the gravel catchshaft in the cent-re toward the outer rim of `the mudgum, thereby causing them to fill thernould better.

Above the press-wings E E, on the shaft D, is

placed a series of curved and bevelled cutters or workers,\F F, which, when they revolve with the shaft,

work the mud downward in the mud-gum toward thel y in which the foot d of the rack Hv is placed.

The rack H is formed of a frame, of any suitable size, having rollers e e running across the same, from the front side to a cross-bar, f, in the frame, which cross-bar is placed at such a distance from the rear .side of the ii'ameas to form a space at the rear end of' the frame equal to the width of the mould.

In this space is placed a series of rollers, g g, running at right 'angles from the rollers c e.

By this construction of the rack there will be little Vor no friction of the moulds, as the moulds are always ou rollers, they being put ou endwise on the rollers g g, for which purpose a roller, h, is placed in the side of the machine, andwvhen filled they are moved outward lengthwise across the rollers e e, by means that will be hereinafter described.

The front or outer end of the rack H is raised and lowered to adjust the mould to the under side of the die-plate C, by means of a bent bar, I, having a crank, i, at one end,

Above the opening where the moulds are moved out after being tilled, is placed a roller, J', covered with cloth, for the mould to pass out under. This roller should he creased about one-siiteenth of an inch over each partition ot' the mould, and will press the brick into theI mould, smooth the top, and do away with all feather-edge. The cloth being wet prevents the mud 'from adhering to the roller.

The journals of the roller J pass through slots in standards K. K, and have rubber' springs above them in said slots, so as t'o allow the roller to yield slightly, if necessary.

On the opposite-side of the machine from that ou which the roller h is situated, is placed a bumper, L, for the mould to strike against when inserted. This bumper consists ot'a bent bar inserted in suitable heads, and adjusted by set-screws' at any point desired, as shown in fig. 2. l

' edge of the frame It, in suc-h a manner as to be even with the under side of the bottom l.

In the frame mv are secured a series of partitions, n n, which fit in the grooves on the sides of the frame 7c, and are of the same height as this latter frame.

The ends of the frame on are provided each with a vertically slotted plate, o, and an car, p, and saidiframe is then attached by means of a screw passing through the slot in each plate o, into the ends ofthe frame k.

After the mould is filled, to empty thes'ame, turn it bottom up, press the thumbs on the bottom, catching the ears p1. at the ends, and raising the partitions n u.'

Above the mud-gum A, upon the shaft D, is placed a colla-r with two cams, N N, which, as the shaft revolves, each in its turn operates upon a friction-roller, O, placed on the under side of' a slotted sliding bar, l), which moves on the upper side ofthe machine, and is guided in its movement by means of'flanged rollers r r, as shown in fig. 1.

The cams N N bulge considerably from the eye, so thatthcy give a straightforward push, instead of pressing sideways 0n the slotted slide when it start-s t-o push it forward by the friction-roller.

Upon the slide P are secured three bars, R It, forming a triangular fran'ie, to which, on each side of' the machine, is pivoted a lever, S.

This lever extends dow'n along the side of the machine, and is at a suitable point pivoted to another lever, T, which in turn is pivoted to the side of the machine.

One end of the lever T is slotted, and adjusted at any point desired by a set-screw, s, so as t-o lengthen or shorten the stroke, to snit the distance the mould is to be moved when it is filled.

The lower endsof the levers S S are connected by a bar, V, which, after the mould has been filled, forces the mould out eaeh'time the cam N moves the slide P.

Under the bottom of the mud-gum A, at the rear side, is a standard, YV, having a rod, t, extending horizontally forward.

'lhis rod is surrounded by a spiral spring, e, which, at its rear end, bears against a slide, w, connected by a rod or chain with the bar V, so that when said bar has moved the mould out, the spring 1: will cause the said bar V, and with it the levers S S, and slide P, to move back to their original position, ready to be again operated by the cam.

Having thus fully described our invention,

What we claim as new, and desire to secure by Letters Patent, is-

2. The combination of the rack H, adjustable 1evers G G, and bent bar/I, with crank fi, when constructed and operated substantially as and for the purposes herein set forth.

2.' The combination of the standards K K and clothcovered roller J, having its yielding bearings in said standards, and with openings placed above the journals, substantially' as and for the purposes herein set forth. V

3. The mould M, composed of the frames k1 m., loose bot-tom l, partitions n n,I slotted plates o o, and bars p p, constructed and arranged as and for the purposes herein set forth.

4. The die-plate O, having the front edge of its under side beve-Hed, substantially as and for the purposes herein set forth.

5. The arrangement ofthe camsN N, friction-roller O, slide l), fra-me R, levers S S, and bar V, all substantially as and for the purposes herein set forth.

6. The arrangement ofthe rod t, springt, and slide tu, connected with the bar V, substantially as and for the purposes herein set forth. v

'In testimony thatwe claim the foregoing, we'have hereunto set our hands, this (ith day of November, 1869.

THOMAS BlSHOP. DANIEL AGNEW.
