BRICK OR TILE MACHINE.

SPECIFICATION forming part of Letters Patent No. 507,798', dated October 31, 1893.

Application led January 25, 1893. Serial No. 459i713 (N0 model- To a/ZZ whom it may concern:

Be it known that I, EGBERT M. FRnEsE, a citizen of the United States, and a resident of Galion, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Brick or Tile Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make Aand use the same, reference being had to the accompanying drawings, which forni a part of this specication.

My invention relates to that class of brick or tile machines in which bricks or tiles are automatically cut from a moving column or bar of clay issuing from the die or dies of a clay working machine.

The prime object of my invention is to provide automatic cutting devices drivenvfrom the clay machine or other source of power, which act upon the column or bar of clay to sever the bricks or other objects therefrom.

It is also an object to provide improved frictional devices, whereby the speed of the cutting mechanism is governed and regulated by the speed of the moving column or bar lof clay, any variation in the speed of the clay, causing a coriesponding variation in the speed of the cutting mechanism.

There are other object-s which will be'apparent to those skilled in the art, and which need not be enumerated in detail.

The invention consists in the novel construction and combination of parts, hereinafter fully described and claimed. l

In the accompanying drawings: Figure 1 is a plan view 0f a brick or tile machine, constructed in accordance with my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a cross section, on the line 3 3, Fig. 2. Fig. 4 is a cross section on the line 4-4, Fig. 2. Fig. 5 is a central vertical section through the cutter carrying rings; showing two modilications in the construction thereof. Fig. 6 is a plan view, showing means for driving the cutting mechanism. Figs. 7, 8 and 9, are detail views showing the means for regulating the tension of the cutting wires. Fig. 10 is a detail View showing the means for connecting one end of the cutting wires to the annuli. Fig. 11 is a view 0f the end of one of the cutting wires.

In the said drawings, see Figs. 1 and 2, the

reference numeral 1 indicates the die of a clay working machine, and 2 the belt which receives the clay as .it emerges from the die. This belt passes over pulleys 3 and 4, respectively, fixed to shafts 3a and 42L journaled in the front and rear ends of a table, consisting of side'bars 5, flush with the upper surface of the belt and supporting legs or uprights 7, s ecured to the base 7a'. Intermediate of their ends, the side bars are provided with rollers 8, for supporting the belt, and preventing it from sagging. 'Journaled in bearings 9, secured to said base is a horizontal shaft 10, which is driven fromsome moving part of the clay machine, or other source of power, and

carries at its rear end a bevel pinion 12, which meshes with a bevel gear 13, mounted upon a transverse shaft 13, journaled in frames 14, secured to the cross pieces 15, of the base 7a. This shaft carries a pulley 16, Fig. 2 around which, and a smaller pulley 17, fixed to a transverse shaft 18, journaled in said frame above and at one side of said shaft 13a, passes a belt 1,9 for conveying the cut bricks or other objects, away from the feeding belt 2. This belt also passes overA pulleys 20, located at the front and rear ends of a table, similar to that which supports the feeding belt. This conveyer belt is locatedv at the rear endof the feeding belt, so "as to receive the bricks as they are cut.

Securely' bolted to brackets 2l, having hubs `23, which are'journaled on the shaft 4a of the rear pulley 4, see Figs. l, 2, 3 and 4, is a casting 24 preferably circular in form and provided with an eccentric or other form of opening 25% of the feeding belt, so that its opening will register with the moving column o r bar of clay, as seen in Figs. 1 and 3. On its outer face, it is formed with a circular groove or recess 25h, in which is located a rotatable annulus or ring 26 having a series of cogs upon its periphery. The meeting surfaces of the annulus and the casting are formed with semicircular grooves 26 to receive balls 27, see Fig. 5, forming ball bearings for the annulus,

so as to reduce the friction to a minimum.

This casting is located just in rear IOO lar casting 52,` having an annulus 34, Fig.'5. This casting, and its annulus, are exact duplicates of the casting and annulus before described, and further description is therefore not deemed necessary.

Journaled in bearings 35, formed in an eX- tension 21, of one of the brackets 21,see Figs. 1, 2 and 6, to which the casting 24: s` bolted, is an inclined shaft 36, having near its rear end two pinions 37 and 38, which mesh respectively with the cogs of the two annuli 26 and 34E. This shaft aty its opposite or front end, is provided with a pulley 39, which is connected lby means of ra looserbelt 40, with a pulley 41, on the main `shaft `10. See Figs. 1,2, 3, 4 and 6.

Pivoted to the base7, are two inwardlyfextendiuglevers 42, onev on` each-side. ofipulleyI .41, and provided at their innerer freer endsf 4with `al tightening pulley 43,=whichi rests upon` -the beltAO. :See `Figs. 3 andai. {Cnetof the levers-42, `atitsiinner end, is; provided withra cleat "45,1upon which rests one end ofran-in-l wardl'yfextending lever 46,1fulcrumed 'upon the `#shaft 136, the opposite'or `outerrend ,o'fj .which t is provided with aflloose bevel-pinion.'

It will be noted that thelwire engages with one of the notches in the yhand-wheel, thus preventing the hub from turning, the coiled spring regulating the tension of the wire.

Secured to a bracket, on one side of the feeding table, see Fig. 3, is an inwardly ex- `tending spring arm 65, having a loop67, at its inner or "free end and carrying a wooden block 68, which lies in the path of the wires during their movement, and serves to clear the same from any dirt that may be adhering thereto.

'Before describing the operation in detail, it should be statedvthat the castings-and annuli,mustbe=inclined atzanacute angle to the path of travelof `thecolumnof clay, asif theyy were -,perpendicular,` or at right angles thereto, an angular cut-would beV made, owing towtheimovelnent ofthe clay. dtshould also be stated,;that the ,cutting=-mechanismshould be soitin1ed,astorrotateormoveat-acertain rate, `with relation tto r.the movinygm` claywand -meansprovided,i1so thatfwhen thespeed of the clay-increases or decreasesitheffspeedof -the cutting ,devices must beacorrespoudinglyva ried, as otherwise, the bricksfcutawouldfnot beef .uniform thickness,fandthe,cutrwould `not beperfectlyfstraight. rBearingthesestatelments inimindfthe. operationaisasfollows:

The speed .of -said pinions V48 and ,'49 fbeingxvariedythe pinion .47 vwill be fforced eithemupwardlyor downwardly, turning lever 4:6, on itsffulcruln and causing thetightener pulleyto bearwith more or less pressure on the belt 40, and, the' latter to bind tighter or looser on the pulley V41. If the clay and feeding-belt be traveling too fast, the feed of the pinion 49, will be accordingly increased, and run at a higher rate than pinion 48. These two pinions now moving at different rates will cause the `lever 46 to turn' on its fulcrum lin the direction of the least resistance of the pinion 47 on the end thereof. In this instance, the pinion 49, traveling the faster, the resistance would be less in the direction of its rotation and the inner end of the lever Will be depressed causing the tightener pulley to bearv with greater pressure on the belt, which will then be Y. caused to bind more tightly on pulley 39, and

the speed of shaft 36 be increased until pinions 48 and 49 again rotate at the 'same speed.

If, on the contrary, the speed of the feeding belt decreases, a reverse movement will Ybe given to lever 46, easing thetightener pulley,

and. allowing the belt to slip on pulley 39 and its speed decreased. As the bricks are cut from the bar of clay, they pass onto the conveyer belt. v v

I have described the castings and their annuli or rings as being duplicates vofeach other, but-it is obvious that the outer casting and its annulus may be dispensed with, and. an ordinary wheel or even a crank be substituted therefor, with which the cutting wires may be connected. In fact, any suitable de- Vice may be substituted therefor, which will accomplish the essential object of the invention, which is to give to the cutting wires a combined transverse and vertical movement down through the bar of clay, and then around out of the path thereof, and up over the same to make a new cut. I have also illustrated the axis of the annuli or rings as being in a horizontal piane, but it is obvious that the plane thereof, may be at an angle to the line of travel of the clay, without departing from the invention. Y

In the modification of the'annulus 34, and casting 32, the friction ballsY are dispensed with and a groove and ilange provided as in the ordinary eccentric and its strap for actuating the valve of a steam engine. See Fig. 5. Having thus described my invention, what I claim isr l. In a brick machine of the character described, the combination withy a conveyer, of two rotatable carriers, one of which has an opening coinciding with said conveyer, and a horizontal cutting wire moving transversely across and above and below the ,path of a column of clay carried by said conveyer, substantially as described. t v
