Toollfwiomitmag/concern: A

Be it known that l, FnANK A. HoILEs, a citizen of' the United States, residing at `Alliance. .in the county of Stark and State of Ohio, have invented a new and useful Brick-@rnaineuting Device, of which the following is a specification.

This invention relates to improvement in 'brick ornamenting devices and has more especial reference to a device of that characich is used in cooperation with a brick which employs what is known as mud process'of making brick by wliicn a column of clay is formed in aldie and carried away upon an endless Vconveyer to a brick cut-off table which cuts the clay ir o brick of the proper size.

of this invention is to provide pied to act upon the top and side he clay column for the purpose of producing an ornamental textile effect similar to a rug or carpet upon said faces. After the clay olumn is carried to the cut-ofi' table and cut/into the brick of the proper size each brick will ne ornamented upon its and endswith this textile appearance. [i further object is toV provide a device of the character referred to in which a rotary A is ployed for the purpose of tearru layer from a face of the clay ici or shredding the material revu the surfaces of the co1- .ing the same again upon column. from which it was equally distributing the shredded of the clay thus removed. fi il'urther object is to provide in coopera in with a rotary device as above described, means for causing the shredded or grated material to lagain adhere to the clay column, giving the proper textile eect.

`With these objects in View the invention consists in the novel construction and ar rangement ofA parts, hereinafter described, illustratcd'in the accompanying drawings,

pended claims, it being understood that va. rions changes in Athe form, proportions, size and minor details of construction may be made within the scope of the appended cla' s without departing from the spirit or sa' icing any of the. advantages of the in- ;cu.' ai.

e drawings: Figure 1 is a side elevaof a device constructed in accordance invention, parts being broken.

away for the purpose of illustration. Fig. 2 is a top plan view of the same with some of the parts shown in section. Fig. 3 is an enlarged sectional view through the rotary cutter. Fig. 4 is a detailed perspective view of one of the spades which is carried by the rotary cutter. Fig.V 5 is a similar view of a slightly modified form of spade. Fig. 6 is a horizontal sectional view through one of the'brackets and bearing blocks. Fig. 7 is a fragmentary view of one of the finished brick formed with this device.

Similar numerals of reference indicate corresponding parts throughout the several figures of the drawing.

In the present method of forming brick having a textile appearance the face of the clay column is first acted upon by the rotary cutter which removes the greater part of the material from the face of the column and shreds or grates the same after which it is deposited again upon the face of the column from which it has been removed. In order to cause the particles of clay thus deposited upon the clay column to adhere thereto a fine jet of steam is directed upon the face of the column after which the column passes beneath drying rolls and for further drying the clay electric fans are used as shown at 42, Fig. l. By this process the particles of clay which have been removed and again deposited upon the face of the clay column will be caused to firmly adhere thereto.

More specifically describing the mechanism illustrated in the accompanying drawing the numeral 1 indicates a die such as is ordinarily used upon brick machines of that character which employ a stiff mud rocess and 2 indicates a portion of the rick machine. These parts are of the ordinary construction, well known to thosev skilled in the art and need no further mention here. A clay column is shown issuing from the dieand is designated by the letter A. Y

Side frames

3 and 4 are supported upon the die to which they are attached by means of bolts 5 or their equivalents. Brackets 6 are carried upon the

frames

3 and 4 and bearing blocks 7 are slidably mounted upon said brackets, each off'said bearing blocks being provided with a slot 8 through which a screw 9 is passed, said screw engaging a suitable screw threaded socket `10 .in the bracket for the purpose of rigidly holding roo Q messo@ the bearing block in the proper vertical adpistincnt. A set screw 11. is provided for ad- }ustmg the vertical position of the bearing block. A shaft 12, preferably provided with a central Si'iuared portion '1.3, is journaled in the hearing block 'i' and is provided upon one extremity with a drive pulley` to ivhich a suitable belt attached to any source of pover may be attached. rl`eeth are provided uponv the shaft l2, said teeth being preferably passed through apertures 1:5 in the squared portion of the shaft 'and held in position therein by means of set screws 15. it is preferable to arrange two oppositely dis- `l5 posed staggered rows of these teeth, one rovv' beinff made up of teeth having blades which We term spades, said spades being designated by the numeral 17, the opi'iosite row being made uy if sharpened, pointed teeth 18. Of course, if desired all of the teeth could be of the form provided with sharpened points such as designated by the numeral 18 or if desired they could all be of the spade type, but with the arrangement above referred to it has been found by experience that a more desirable result may be obtained. It will be noticed that the teeth terminate a short distance inside of the longitudinal corners of the clay column in order to prevent the corners of the clay column from being torn avay. lf the face of the Clay column was not acted upon by some other cutting mechanism after the column had passed beneath the rotary cutter ust described, it is obvious that a blank marginal space would be left along each corner of the column and although in the produc-tion of Some bricks it may be desirable to have suoli a blank space the general demand is for a brick` the entire 49 face of which will present a uniform appearance and for this purpose I provide additional rotary cutters which are adapted to treat the face of the column adjacent the longitudinal cornia's thereof in the same manner that the entire face of the column is treated.

A shaft 1), similar to the shaft 12 is located at an angle to the shaft 12 and is mounted in suitable bearing?, blocks 20, which are adjustably mounted upon brackets 21 similar to the brackets 6, these brackets being carried upon the

frames

3 and 4. The shaft 19 is provided with the squared portionl and carries two staggered rows of teel'fi, the sharp pointed teeth nich as designated h v the numeral 18 being found preferablc. ik driving pulley is provided upon our` om' rer of the shaft i9 and is adapted to be driven by a suitable belt in the direc tion shown by the arrow' thereon. .lt will he no rrd that the teeth upon the left extremity 2t 1".) terminate short of the. longihile the teeth cobinni.

rlhus as the shaft i is rotated the teeth at the extreme right A thereof Will enter the upper face of the clay column at an angle thereto, thus roughening the upper surfaces of the column along the'right, longitudinal 70 corner. For the purpose of cutting the upper face of the clay column along the left longitudinal corner thereof a shaft 24 is presided, similar to the shaft 19 beine4 pla i at an angle opposite to the shaft 19 75 and journled in bearings t5 carried hy the brackets lo This shaft is provided with a squared nortion and teeth 18 terminating short of the right, longitudinal corner of the clay column and extending beyondthe left 30 longitudinal corner thereof, a drivepullev 38 being provided and adapted to be driven in the direction of the arrow shown therein, thus roughening the surface of the clay column adjacent to the left longitudinal cor- 8i,- ner thereof,

If desired the shafts 19 and 2d instead of extending entirely across the face of the clay column may only be of suflicient length to worh' upon the face of the column ad- 9o jacent the longitudinal corners and for producing a brick wherein it is desired to procuro a coarse textile effect upon the face this would be preferable but with the diagonal shafts extending entirely across the clay column as shown in the drawings, the face of the clay column is cut at three different and the material is shredded or grated much finer than in the case above ref ferred to, producing a liner textile appearance.

As the particles of clay which are tornv and shredded by the rotary cutters are again deposited upon the face of tte column of clay they will not adhere very tight-ly thereto and for the purpose of causing this mass to adhere irmly to the body of the clay column, a steam jet is directed thereon for the purpose of moistening the material thus ground up, causing it to adhere to the column. This device consists of steam nozzle 2i) placed beyond the rotary cutters and located a short distance above the column, one end of said pipe being closed by a cap 30 and the opposite end being connected to a steam line 31. Spaced apertures 3Q are provided in the lower side of the steam nozzle 29 for the purpose of allowing small jets of steam to spout upon the face of the clay column, For the purpose of drying the face of the column thus dampened one or more drying rolls are used. As these rolls are similar' it is only thoughtnecossary to describe the mechanism of one. Each roll is composed of a. hollow metallic cylinder 33 provided with a cover 3l of felt or similar material. A hub 35 is located at the center of the roll and supports the roll by means of :spokes S6, a shaft 37 being;` loeatid through the hub 35, said shaft being mount- 130 edwithin suitable slots`37 in each of the. side frames 3 and 4 to allow the roll to always remain in Contact with the face of the clay column. A Bunsen burner 38 enters the cylinder from each side and extends to a.

point adjacent the spokes 3G, said burners being connected to gas lines 39 provided withr shut-off valves 40. As the clay column passes beneath the drying rolls the movement of the column will Cause the rolls to continually rotate, the heated surfaces of the rolls ending to dry the surfaces of the col umn. For the purpose of preventing the brick from adhering to one another when they are hacked the felt covering upon the drying rolls is lubricated, the means for doing this being shown as lubricating cups il. which are supported in any suitable manner above the rolls and so adjusted that. oil will continually drop upon the rolls.

.As a further means for drying the tace of the clay column a series of electric fans is used. n In the drawings a fan 42 is shown supported above the column and adapted to direct a current of air upon the face of the column for drying the same, but it Will be understood that any number of fans found necessary may be used.

For the purpose of producing an effect upon the side of the clay column similar to that-produced upon the top face. a rotary cutter is employed. and adapted to engage the side face of the column. This cutter is preferably placed at an angle as shown in the drawings andconsists of a shat't `iour` iialed in a bearing 44 adjustably fari-ivd in a bracket 45 which is mounted upon a frame 4G. The shaft 43"is provided with teeth 18 and with a driving pulley 47 adapted to be rotated in the direction indicated by the arrow thereon by any suitable means. A steam nozzle 4S similar to .the nozzle 2i) is, placed adjacent the rotary 4cutter just de scribed and is adapted to direct steam upon the side taceof the, clay column. A drying roll 479 is supported by the frames 4 and 476 and is provided with a gas burner 50.

All of the rotary cutters are rotated very rapidly, about three hundred revolutions a minute having been found vby experience to produce the desired result. As these cutters rotate the teeth thereon engage the tace ot the clay column tearing up tlbe surface and removing a great portion of the material therefrom. the portion removed being shredded and pulverized and distributed evenly upon the tace from which it has been rciiioved. and after the clay column has been acted upon liy the steam viets :ind been cut contem'ilated embodying my invention I desire to be not limited to the details otl such disclosure. 1for. in the l'urtlier practical application ot my invention. many changes in lorin and construction may be made, as circumstances require or experience suggests, without departing from the spirit ol.l the. invention. within the scope of the appended lclaims.

In other devices the usual custom for scouring theneccssary power and motion to ornament the face of the clay column has been to depend on the power and movement of the clay column for saine. ln this device the source ot power and niotiiui is altogether outside ot the claj' ri'ilunin: and the teeth tearing the face of the clay column are not continuously in the clay. but each engages with the surface ot the clay column only moiiicni'arily and travels in the saine direction as the column of clay.
