MECHANISM on CUTTING WIRE-GUT Baron.

Specification of Letters Patent. Patentod Sept. '7, 1909.

Application filed October 2, 1907:. Serial No. 395,584.

, To all whom it may concern:

lle it known that I, FRANK B. DUNN, a culzen of the United States, residing at (lonneaut, in the county of Ashta'bula and State of Ohio, have invented certain new q and useful Improvements in Mechanism for- Cutting lVire-(Jut Brick; and I do hereby declare the following to be a full, clear, and

exact descriptioinof the invention, such as 0 will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom anying drawings, and to the letters of re erence marked thereon, forming-part of this specification.

My invention relates to wire-cut brick, and has for its obj ect the production of wirecut brick having wire-cut ribs on one side and corresponding wire-cut depressions on the other, and mechanism for cutting such ln'lck. v 4

vAs iswell understood in the art, wire-cut brick are produced by passing one or more wires through a column of clay resting on a platen having slots therethrough for the passage of the wires, as the column of clay is forced out thereon from theclay mixer through a suitable die. To accomplish the desired result I make the slots in the platen virregular so as to varythe line, of the'travel of the wires therethrough and through the column of clay, from a direct line to an irregular line of travel, thereby leaving wirecut grooveson one side and wirecut ribs on the opposite side of e ch brick out. A convenient mechanism for producing this result is hereinafter fully set forth and described,

and illustrated in the accompanying draw-v ings in which Figure 1 1s a transversexview in section of an ordinary rotary brick cutter, embodying a form of mechanism for cutting brick made 1n accordance wlth mymventmn. Fig. 21s a side view ofa section ofan lmproved platen, suitable for carrying out my invention, looking in the I in Fig. 1. Fig. 3 is a top or plan view of y direction of the arrow a section of said improved platen looking in the direction of the arrow y in Fig. 1. Fig.

4 is a perspective view of a wlre-cutbrick made in accordance with my invention.

' The brick cutting machine illustrated in the accompanying drawings is of vthe ordinary type, in which end rings are "rotated in supportingframes B and drlven by ears ame B having a central ring 'D upon which rings D are mounted and from which cut-ting wires E extendto bars A between the rings A. The platen-sections F upon which the column of clay from the v the of the brick machine travels-through the cutter, are secured to,,th e,central-bearing D by means of upwardlyiextending arm F, between which the rings D"'rotate. operation, the cutting mechanism and platen travel in unison with the travel of the clay column issuing machine during the cutting operation, and is provided with the usual mechanism lot shown) operating periodically to automatically move said mechanism in the opposite direction from that of the travel of the clay.

column preparatory to making another out, all which features are common in brick cutting machines. The novel features which I have added'to this mechanism and by means whereof I am enabled to produce wire-cutbrick with wire-cut ribs on one side and wire-cut grooves on the opposite side, consist substantially in'making the slots f in the platen with curved offsets f on one side of the grooves f, and opposite said oifsets f, I preferably pivot rollers G,.so that as the cutting-wires E pass through the slots 7 they contact with the rollers G and are defiected thereby into the offsets f.

To guide the cutting-wires E at the upper edge of the brick, I secure, slightly above'the brick,to the armsF which support the pl atensections F, guide-sections H, parallel to and corresponding in width to the platen-sections F, and the slots h between these guide-sections II are also provided with offsets h, and with rollersG opposite said offsets, so that as the"cutting-wires E pass. the rollers G they are deflected into .the offsets hso as toproduce grooves 2' of equal depth from edge to' edge of the brick I on one. sid'e,.and ribs 11 of equal height from edge to edge of said brick on the opposite side thereof, thus producing a wire-cut. brick with transverse wirecut ribs on one side and wire-cut transverse grooves on the other. I s v Herei before-I havefd'scribed a suitable form of mechanism for producing wire-cut :brick with ribs on one sidefand grooves on the other. It is' obvious however that many forms of mechanism may-be devised for producing wire-cut brick with transverse ribs and grooves thereon without departing from. v

the spirit of my invention. 'Iherefore hav- In I from the die of the brick ing described suitable mechanism for producing wire-cut brick having transverse grooves in one side and transverse ribs on the other, what I claim as new and desire to secure by Letters-Patent is:

l. The combination in a machine for wirecutting brick from a continuously moving column of clay-comprised substantially of mechanism operating'one or more tensioned cutting wires, a transversely slotted platen upon whlch the clay-column is supported and through which t: 1e tensioned cutting wires pass traveling 1 unison therewith and with the clay column during the cutting operation, and means in said platen slots for deflecting the cutting wires as they pass through said slots and a column of clay supported on said platen, substantially as set torth. v

2., T he combination in a machlne for wirecu'tting brick from a continuously moving column of clay comprised substantially of mechanism automatically operating cutting wires, a transversely slotted platen mounted in the path traversed by said cutting wires and traveling in-nnison therewith and with the cla column during the cutting operation, and 0 sets in said platen slots-for deflecting the cutting wires from a straight line of travel during their passage through said slots and a clay column' supported on said platen, {substantially as set forth. 3. The combination in 'a machine for wire-.' cutting bricklfr column of clay comprised subsantially ofautomatica l l operated cutting. wires, a

transversely slotted platen mounted in the path traversed by said cutting; wires and travelin in unison therewith and with the column f clay during 'the cutting operat on, atransversely slotted guide above the trans-v versely slotted platen, and ofi'setsin the slots in said platen and in the slots in said guide,

whereby the cutting wires are equally dea continuously moving;

flected from a direct line of travel through said slots during the cutting operation both at the upper and lower edges of the brick b'eingcut, substantially as set fortlil 4. The combination in a machine for wirecutting brick from a continuously moving column of clay comprised substantially of mechanism automatically operating cuttin Wires, a transversely slotted platen mounte in the path of said cutting wlres and travel-- mg in unison therewith and with the clay co umn during the cutting operation, ofisets in the slots in said p1aten,"and' rollers-in the;

for the passage of the cutting-wires. corresponding to the slots between the platen sections, offsets in the slots between the guide-sections, and rollers pivoted to the guide-sections opposite the ofi'sets therein, whereby the cutting wires areequally deflected from a direct line of traverse in the slots between the platen-sections and guide sections at'the upper'and lOWI' edges of a brick duringthe cutting thereoflosubstantially as set forth. 7 e v 1 f In testimony whereof I aliix my signature, in presence of two witnesses.
