BLOCK OR BRICK MAKING MACHINE.

Application filed September 12, 1919.

T0 aZZ whom it may concern:

Be it known that I, RICHARD RYAN, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Block or Brick Making Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to block or brick making machines and has special reference to such a machine in which the aggregate employed therein includes cement, the product of which is commonly known as concrete.

While my invention relates particularly to a combination of mechanical elements the employment of such mechanism involves a novel method which forms a part of my present invention.

The principal object is to provide a simple and practical concrete brick forming machine.

Another object is the production of a novel and simple method of simultaneously forming concrete bricks and storing them in a steaming room.

Still other objects and advantages of the invention will appear during the further description thereof.

In the accompanying drawings forming part of this application and in which like reference characters indicate like parts:

Figure 1 is a vertical sectional View through abuilding or room employed for steaming concrete bricks during the production thereof.

Fig- 2 is a transverse sectional view of the brick-forming trough taken on the line 2-2, Fig. 1:.

Fig. 3 is a top plan view of Fig. 2 and Fig. 4 is a reduced plan view of a build ing in which my brick-forming machine is employed.

1 represents a building of any desired construction built for the purpose of steaming or otherwise treating bricks, such being common in the art. In one end of this building I preferably provide an opening or door 2 sufiiciently large to receive the complete brick making machine and which may be placed within the building or removed therefrom as desired or if, in the event of the employment of a large building having a plurality of steaming rooms therein, the

Specification of Letters Patent.

machine may be transferred from one room to the other as is evident.

It is customary practice to form such bricks and subsequently transfer them to the steaming room, whereas in my present invention the bricks are formed as near as cated at at and the upper story is of sufficient height to accommodate a suitable concrete mixer and the workingthereof, such a mixer being indicated at 5.

An open slot 6 is formed in the fioor 3 longitudinally of the room in which the bricks are to be stored, and a track 7 is provided adjacent the slot for the accommodation. of the concrete mixer 5. A suitable track is also provided on the main floor of the building or room in which the bricks are being formed and stored. This track is for the accommodation of the brick-making machine which is provided with suitable wheels for cooperation with said track, or if found more convenient it is apparent that the tracks may be wholly dispensed with and both the brick making machine and the concrete mixer operated upon flat flangeless wheels if preferred. 2

In practising my novel method of making bricks which includes the curing of same in the steaming room, the first step taken is the passing of the brick-making machine into the building or room in which the curing process is to take place together with the concrete mixer in the story above the brick machine and which latter, during the process of brick making is required to afford a continuous supply of concrete to the machine below, the mixed concrete passing through the slot 6 in the floor 3. These machines are placed a suitable distance from the end of the building or room farthest from the entrance and convenient for the pi'lers to receive the bricks from the machine as they are formed and stack same in the end of the building or room. As the stacking or piling up process of the bricks fill the room the machines are manually backed away therefrom so that when the room is filled with bricks the machines will be ejected, and ready for subsequent filling of the same compartment or moved to other rooms or buildings for a like purpose.

It is not necessary to describe'the structure or operation of the concrete mixing ma chine as such is not essential to this invention but the brick-making machine involves novel combinations of parts that I will now proceed to describe, it forming an essential part of the invention.

\Vithin the frame 4 is mounted a platform or table, sections of which are indicated at 8, 9 and 10 and upon which is formed 7 a suitable trough, the width of which is the exact length of the bricks to be made, said trough comprising the side walls 11, cooperating with the table top in forming said trough. In approximately the middleof the frame 1 are two large vertically spaced rollers 12 and 13 and upon either side of the latter are two vertically spaced smaller rollers 14., they being par allel with the roller 13 and but a short distance from either side thereof. About these latter five rollers is placed a canvas or other suitable belt, indicated at 15, and which passes over the sections 8 and 9 of the bottom of the trou hand forms a movable bottom therefor. lDirectly above the section 8 of the table top is the feeding endof a suitable inclined spout 16 which feeds con crete. on to thebelt in the trough. I have shown-at'17 a section of the wall of the spout 16 as being vertically reciprocable in any desired manner for the purpose of governing the amount of concrete which is allowed to pass intermediate of the rollers 12 and 13 and by which it is obvious the density of the composition forming the bricks may be controlled.

An electric motor is indicated at 18 and drives a counter shaft 19 which in'turn operates the feed roller 12 and upon the counter shaft 19 is any suitable form of friction clutch pulley 20 controlled by the rope 21, such pulleys being capable of quick adjustment, as is well known in the art, and by which the roller 12 may be readily stopped and started. 1

It may be found necessary to apply power to some one of the rollers 13 or 14:, but from experience thus far gained I am of the oplnlon it Will answer every purpose to have power applied only to the roller 12 and which when in action will cause the belt 15 to revolve about the rollers 13 and 14 as the concrete is carried forward in the trough.

At the end of the trough and adjacen the bottom section 10 is a frame structure indicated at 22 which supports a suitable platform for the reception of the pallets upon which the bricks are formed, one of 7 same.

which is indicated at 23 is flush with the bottom of the trough and in receptive positionfor the bricks... A laterally projecting extension 2 1 is formed upon one side of the frame 22 which supports the series of thin metal blades indicated at 25 which are designed to be manually forced through the body of concrete when the latter is in the trough on the pallet and ready for forming into bricks.

The knives 25 are attached together at their outer ends by the'cross member 26 which carries the operating handle 27 and may or may not be mounted upon suitable rollers or wheels 28 for convenience in reciprocal manipulation. V

Slots 29 are formed in one of the side walls 11 of the trough dividing it into sections and which sections are held together by a superimposed member 30, allowing the knives 25 to freely pass through when in the act of dividing the concrete within the trough.

The opposite side wallof the trough and for a distance the exact length of the pallet 23 as indicated at 31 is pivotally mounted upon suitable hinges 32 in the frame 22 and capable of being prostrated uponv the laterally projecting extension 33 similar to the extension 24 the same being for the disposition of the pallet carrying the bricks formed thereupon.

Spring controlled dogs or catches 34 34 are mounted upon either upper corner of the side section 31 of the trough and which dogs are designed to automatically catch over the stationary edges of the side wall 11 adjacent the ends of the section 31 when the latter is in. its uppermost closed position. These dogs are provided with forwardly extending inclined portions 35 which are engaged by an inclined block 36 carried upon the outermost ones of the knives 25, when the latter abut the inner face of the section 31. 1 By this engagement it is evident. that the dogs are obliged to release their hold upon the side 11 of the trough when the knives have fully passed through the contents thereof and onfurther advance of the knives 25 the section 31 will be prostrated to a position parallel and flush with that portion of the frame 22 upon which the pallet is supported, thus permitting of the pallet with its load of bricks being forced directly. across said prostrated section onto the platform 37 provided forv On withdrawal'of the knives 25 the section 31 will resume its position, forming a contlnuation of the side wall 11, by the action of a suitable counter-weight 38 attached to the arm 39 and carried by the section, or any other convenient means for automatically raising it. Then a fresh pallet. is placed within the trough and the feeding along of the concrete therein again resumed by the manipulation of the control of the friction pulley 20. When the pallet of bricks is thus prepared an attendant will place same in the pile of like units in the building or room where they are thus stored preparatory to the steaming process.

It is evident that Various modifications and changes in the embodiment of the invention here shown may be resorted to without departing from the spirit thereof.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

The combination with a portable brickmaking machine of the character described having a suitable material feeding device associated therewith, of a downwardly inclined feeding spout in the brickmaking machine, two vertically spaced feeding rollers adjacent the discharge end of the spout, a trough intermediate of the rollers into which the spout discharges, an endless belt intermediate of the rollers, forming a portion of the bottom of the trough and onto which the material is discharged from the spout, means for intermittently operating the brick making machine, means at the discnarge end of the spout and adjacent the feed rollers for regulating the amount of material fed into the trough, and means at the opposite end of the trough for forming the contents thereof into a plurality of individual parts, substantially as described.

In testimony whereof I hereunto afliX my signature in the presence of two witnesses.
