BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 625,866, dated May 36, 1899.

Application filed October 9, 1897.

To all whom it mag concern.- 7

Be it known that we, THEOPHILE EDOUARD AYoT'rE and ARTHUR ALBERT CHAEBON- NEAU, of Montreal, in the Province of Quebec and Dominion of Canada, have invented a new and Improved Brick-Machine, of which the following is a full, clear, and exact description.

This invention relates to machines for the manufacture of brick, artificial stone, and ornamental brick; and the object is to provide a machine of this character that may be operated with dry or semidry clay and with which a comparatively large number of brick may be formed with the help of one or two operators. I

We will describe a brick-machine embody ing our invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying. drawings, forming a part of this specification, in which similar characters of reference indicate corresponding-parts in all the views. j

Figure 1 is a side elevation of a brick-machine embodying our invention. Fig. 2 is an end view thereof. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 isa section on the line 4 4 of Fig. 2. Fig. 5 is a plan view of a mold employed.- Fig. 6 is an edge View thereof.

Fig. 7 is a plan view of a carrier-rack em-,, ployed. Fig. 8 is a plan view of a clay-cut ter employed, and Fig. 9 is a detail showing a plunger-operating mechanism.

This machine is double-acting-that is, it, is provided with two sets of pressing devices operating alternately and in conj unction'with j a reciprocating mold.

Referring to the drawings, 1 designates a frame, which must be stronglyconstructed, so that it will resist the vibration caused by Mounted to move vertically in suitable guideways at the. ends of the frame 1 are the upper plungers 2 and 3 and the coacting lower plungers 4 and 5. The upper plungers 2 and3 are operated, respectively, by levers 6 and 7, which are fulcrumed at oneend to the machine-frame and have links 8 and 9, extended to the plungers.

The levers 6 and 7 are horizontally disposed,

and from the outer end of the levers 6 arms Serial No. 654,662. (No model.)

similar to the arms 10 and engaging with cams at the opposite end of the machine similarly to the cam-disks 11. The cams for the

arms

10 and 13 are operated by a longitudinally-disposed shaft 14, having bevel-gears 15, engaging with bevel-gears 24 on the shafts 6o 12. One shaft 12 has a gear-wheel 17 secured to it, and this bevel-gear 17 engages with ,a pinion 18 on the shaft of a gear-wheel 19, meshing with a pinion 20, secured to the shaft of a driving-pulley 21, from which power may be transmitted by any suitable motor;

The lower plungers 4 and 5 have link connections with levers 22 and 23. The outer ends of the levers 22 engage in grooves in cam-disks 24*, mounted on the shaft 12, and

the levers 23 engage with similar cams on the shaft operated by the shaft 14. The several plungers have head portions each of a surface area equal to that of a brick or similar article to be manufactured,"and there may be any desired number of these heads on the plunge-rs, equaling, of course, the number of openings in the mold.

The mold, as shown in Fig. 5, comprises a frame 25, having two sets of mold-cavities 26, So

one set designed to be operated in connection with the plungers 2 and 4 and the other set in connection with the plungers3 and 5. The

moldboard or frame 25 is movable longitudinally of the frame 1. provided at its opposite sides with tongues engaging in slideways in the sides of the .frame.

Reciprocating motion is imparted to the moldboard or frame 25 by means of levers 27, fulcrumed on the frame 1 and having link 0 connections 28 with pins extended from the tongue portions of the moldboard through longitudinal slots in the frame. The lower ends of the levers 27 are connected to rods 29, having pins 30 extended into cam-groo'ves-3l 95 of cam-disks 32, mounted on a shaft driven by means of a gear-wheel 33, mounted on said shaft and engaging with a pinion 34 on the shaft operating the arms 13; It may be here stated that the arms 10 and13 are held sub- I00 As here shown, it is stantially in vertical alinement by means of pins 35, extended into slots formed vertically in the side frames 1.

Mounted in the frame 1, between the sets of plungers, is a clay mixing and flushing oasing 36, which may be divided by means of av central partition into two chambers, and in each chamber a shaft 37 is mounted to rotate.

On the shaft 37 are outwardly-extending fingers 38, and at the lowerends of the shafts bevel-gears 40, engaging with bevelgears 41 j on a shaft 42, mounted in bearings on the top of the casing 36, and the outer end of this shaft 42 is provided with a sprocketwheel 43, from which a sprocket-chain 44 extends to a connection with a sprocket-Wheel 45 on the shaft of the driving-pulley 21.

In the lower portion of the casing 36 is a grating 46, having a number of openings equal to the number of openings in each section of the'moldboard and designed to register at a certain time with the openings in the moldboard. This grating 46 consists of upper and lower sections, and between the upper and lower sections a clay-cutting device is movable. This clay-cutting device consists of a frame 47, designed to be reciprocated across the grating and having a number of cuttingwires 48. Reciprocating motion is imparted to "the cutting device by means of a cam 49, mounted on the shaft 14 and in the camgroove of which a roller on an angle-lever 50 engages. The vertically-disposed member of the angle-lever 50 is fulcrumed to a bracket 51, extended outward from the frame, and the upper end of this vertically-disposed portion of the lever is pivoted to lugs 52, extended from the frame 47. The opposite end of the frame'47 has pivotal connection with a link 53, the lower end of which is pivoted to a;

bracket 54, extended from the frame 1.

Secured within the frame 1, below the reciprocating moldboard 25, is a table 55, having a series of openings at each-end designed to register with openings through the moldboard. At the central portion this table will form a bottom for the mold-openings when the clay is pressed therein by means of the spiral blades 39.

Movable at the sides of each plunger-4 and? 5 are carrier-chains 56. These carrier-chains I are reciprocated transversely of the machineframe, and, as here shown,-the chains are extended around rollers 57, mounted on the corners of laterally-disposed frames 58. Re-. ci'procating motion is imparted to the chains:

56 by means of sprocket-chains 59, engaging with sprocket-wheels on shafts of the chain-.-

driving wheels and engaging with sprocketwheels 60, on the shaft 61 of which are mounted pinions 62, engaged by segment-racks 63,

pivoted to the machine-frame,and from which rods 64 extend to engagement with camwheels 65 on the shaft 14.

In operation the clayor other material to be formed will be placed in the receptacle 36, where it will be pulverized by the fingers 38 and forced through the grating 46 into the mold-openings at one end of the moldboard. Then the cutting device will be reciprocated to sever the clay in the molds from that in the receptacle 36, after which the moldboard will be moved to bring its filled molds underneath one of the upper plungers, here shown as the plunger 2. When in this position, the upper and lower plungers 2 and 4 will be moved to press the material in the mold-openings. Then the lower plunger 4 will be moved downward to bring its plunger-heads below or substantially on the plane of the upper stretches of the chains 56, and then a carrier or receiving-rack 66 is to be placed on the chains below the moldboard. The upper plunger 2 will then move downward, so that the plunger heads thereof will force the formed brick out of the mold onto the carrier or rack 66. Then the chains 56 will be operated to move said carrier or rack outward to the side of the machine, where it is to be received by a transporting device hereinafter to be described. While this operation is taking place, clay will of course be fed into the openings inthe opposite end of the moldboard, to be moved between the plungers 3 and 5 and operated in the manner as before described.

It may be here stated that to prevent the sticking of clay to the plungers the said plungers and plunger-heads should be suitably heated. They 'may'therefore be made hollow in the usual manner and supplied with steam.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. A brick-press,comprising two pairs of upper and lower plungers, a moldboard, means for moving the mold-board to the pairs of plungers alternately, a feeder for feeding clay into said moldboard, a cutter operating between the feeder and moldboard,and means for moving the moldboard to and from the pressing-plungers, substantially as specified.
