BRICK, BLOCK, OR TILE CUTTER.

SPECIFICATION forming part of Letters Patent No. 790,170, dated May 16, 1905.

Application filed January 14, 1905. Serial No. 241,160.

ing to be a full, clear, and exact descriptionof the invention, such as will enable others. skilled in the art to which it apperta'ins to make and use the same.

This lnvention relates .to certain 1mprovements in brick, block, or tile cutters; and the Figure 1 is a vertical longitudinal section of frame.

objects and nature of the invention will be other constructions and arrangements within the spirit and scope of my invention.

The invention consists in certain novel features in construction. and in combinations or arrangements of parts, as more fully and particularly set forth hereinafter.

Referring to the accompanying drawings,

the rear portion of the machine. top plan thereof. section taken through the machine in the plane of the cutting-reel. Fig. 4 is a detail enlarged side elevation of the upper rear portion of the machine, showing the cutting-reel. Fig. 5 is a detail perspective of a portion of the endless carrier or table, portions being broken away. Fig. '6 is a detail view of one of the wire-frame-controlling cams, dotted lines indicating the path traveled by said Fig. 7 is a detail elevation of one of the cutting-wire frames of the reel.

The machine shown comprises an endless traveling table or conveyer made up of loosely- Fig. 2 is a connected plates or sections, a frame provid- .ing tracks or'ways for thetable, a rotating cutting-reel driven by engagement with standards rigid with the table-sections, and a roller bed or platform to receive'the out bricks discharged from the table.

The frame of the machine can be of any suitable and, desirable construction, although Fig. 3 is a vertical cross-- I prefer to employ opposite end pairs of posts or uprights and longitudinally-arranged sides carried thereby. 2 are projected upwardly from the frame sides to provide supports for the cutting-reel and the cams which cooperate with the wire-carrying frames of said reel. 3 represents the two longitudinal side walls of the frame, extending from end to end thereof. These sides 3 are arranged inparallel vertical planes and are spaced a suitable distance apart to accommodate the traveling table. Said sides are usually formed with horizontal longitudinal edges and rounded or approximately semicircular vertically-disposed end edges and are pro- The rear end vertical posts vided at their inner vertical faces with inwardly-extending ledges forming the tracks or runways 4:, on which'the supporting-rollers of the horizontal top ply and depending end portions of the traveling table move. At the opposite ends of the frame these tracks 4 curve downwardly or are semicircular, forming vertical curved end continuations of the top horizontal portions of the tracks. The top portions of the track are horizontal and are depressed below the top edges of the sides, and the curved end portions are also depressed or arranged inwardly beyond the curved end edges of the sides.

The horizontal bottom or return tracks 5 are formed in the inner faces of the horizontal beams or'bars 6, arranged at the lower edges of the sides 3, and the tracks 5 project,

inwardly from the inner faces of the bars 6 and are arranged below the top edges of said bars. The frontend of the frame is approximately the same so far as the tracks are concerned as the rear end shown, for instance, in

Fig. 1.

Each plate or section of the traveling table or conveyer comprisesa floor 7, usually recless chain and preferably so that the sections forming the top ply of the table will abut approximately at their ends and form the horizontal top floor or table on which the bar or bars of clay rest and which receive the same from the bar-forming machine, so that the endless table is propelled by the forward movement of the bar or bars of clay. The hinge-pivots between the sections are preferably located below the meeting ends of the sections, and each hinge-pivot is shown consisting of a rod or axle 9 arranged below the plane of the floor 7 of the sections of the top ply and immediately below the adjoining end faces of the sections and loosely coupled in any suitable manner to the end portions of the bottom bars 8 of adjoining sections, so that the sections can freely swing vertically on said hinge-pivots 9. Said hinge-pivots 9 are projected laterally beyond the sections and form the axles for the comparatively small table-supporting rollers 10, located beyond the planes of the side edges of the sections. If so desired, the axles 9 can be loosely confined to the sections so far as endwise movement is concerned, and the rollers 10 can be loose on the ends of the axles 9, as the rollers are arranged at the inner faces of the sides 3 and bottom bars 6 by reason of the depressed tracks. The inner faces of the sides 3 and of the bars 6 will hence confine the rollers against endwise movement from the axles 9 and will also confine the looselymounted axles 9 against endwise movement.

Each section of the table near its rear end is provided with two upright side cutting-reeloperating guide-standards 11. These standards are arranged at the opposite side edges of each section and can be of any suitable and desirable construction, although I prefer the arrangement shown wherein each standard consists of a strip of doubled metal having the lower ends of its legs fitted down on opposite sides of and secured to a lateral projection 12 from the edge of the floor 7. I also provide vertical slots in the edges of the floor 7, into which the metal plates forming the standards fit to add strength to the standards. The front faces of the standards are preferably flat for engagement with the guide-rollers of the cutting-reel, and these front faces of the standards when in their normal positions are preferably inclined upwardly and rearwardly to a slight extent from the perpendicular, as hereinafter set forth.

Each section of the table is formed with a vertical slot 13, extending transversely through the floor 7, from edge to edge thereof, and downwardly through the fiat top face thereof to or approximately to the bottom bars 8. This slot 13 is located near the central portion of the length of the floor 7that is, a short distance in rear of the exact center of the floor 7 and a short distance in front of the standards 11.

The cutting-reel is approximately the same construction disclosed in my Patent No. 770,625, dated September 20, 1904. This reel comprises the shaft 14, arranged a suitable distance above the rear end portion of the horizontal top ply of the traveling table and carried by and turning freely in boxes or bearings in the end posts 2. End heads .15 are rigidly secured to this shaft and at their inner faces are formed with the outwardly-extending slideways 16.

17 represents the sliding cutting-wire frames confined in the slideways 16 to move therein about radially of the reel. At its two outer ends each frame 17 is provided with the guiderollers 18, arranged to engage the standards 11 of the traveling table. Suitable means are provided to loosely confine these rollers to the frame ends, and adjustable books or bolts 19 extend through said rollers and carry the cutting-wire 20, which is stretched between the ends of the frame and the rollers. This wire is arranged eccentrically to the axis of the two rollers by beinglocated a short distance-"say about an eighth of an inchnearer the axis of the cutting-reel than is the axis of the two rollers 18 located with respect to the axis of the cutting-reel.

21 represents the two stop or frame-controlling rollers or projections of each wireframe, which project laterally beyond the sides of the frame to travel, respectively, in the vertical planes of the cams 22 and to engage the top edges of said cams during certain portions of the movement of the frames.

The cu tting-wire frames are equally spaced, and any suitable number of these frames can be employed in the cutting-reel.

The cams or wire-frame-controlling tracks 22 are rigidly secured to the posts 2 at opposite sides of the traveling table and are peculiarly curved at their upper edges to cooperate with the stop-rollers 21, as hereinafter more fully set forth.

A brick-receiving table or platform is arranged at the rear end of the machine and inclined downwardly and forwardly from the discharge or delivery end of the top ply of the traveling table to receive the cut bricks from the table-sections as said sections move downwardly at the discharge end of the machine. 23 is the frame of this receiving table or platform, rigidly secured to the sides 3 of the cutting-table frame. 24 represents looselymounted parallel rollers arranged transversely in this frame 23 and forming a series of closely arranged rollers approximately from end to end of the frame 23 and constituting a roller floor or platform. The rollers at the front end of this platform are reduced in length and are mounted in the angularlybent bars 25 to afford spaces between the bars 25 and the side bars of the frame 23 for the downward passage of the standards 11 of the traveling table. I usually provide the rollers 24 with a soft surface covering 26, composed of any suitable fabric which will act asa cush-' .mit the easy feeding movement of the bricks or to accelerate the movement of the bricks away from the traveling table than by the rollers.

As the bar of clay moves forwardly on the top ply of the traveling table, thereby pro- .pelling the table, the cutting-reel is rotated by the engagement of the guide-standards 11 with the rollers18 of the cutting-wire frames.

rollers 18 engage the standards 11 of an ap-' proaching table section. When the wireframe thus slides forward by gravity, its stoprollers 21 engage the upwardly and rearwardly projected front ends of the earns 22 some where between the points a and 7), Fig. 6, and

the frame is thus stopped from sliding forward from the reel. As the reel revolves the rollers 21 travel on the surfaces of the cams until they reach the points 6. The guide-standards 11 of the said advancing table-section then engage the rollers 18 of said frame and push the said frame back until it reaches the abutments at the inner ends of its slideways 16, thereby causing the stop-rollers 21 of said frame to move along the imaginary line b c and away from the cam-surfaces. The downward cutting movement of the wire then begins,and the guide-rollers 18 move down along the guide-standards 11, and the stop-rollers 21 move concentric with the reel-axis along the imaginary line 0 d. When the stop-rollers 21 have reached the point indicated by d, Fig. 6, the wire-frame is in the vertical position, the cutting-wire is in the lowest point in its path of movement, the cut'through the clay bar has been completed, and the stop-rollers 21 are again in contact with the surfaces of the cam. The wire-frame then starts on its upward movement, the cutting-wire belng located down in the slot 13, and the stop-roll-' ers 21 travel along the cam-surfaces rearwardly from the 'point (Z and upwardly and rearwardly along said curved cam edges until the point e is reached. When the point a is reached, the cutting-wire is located between and out of contact with the two severed edges of clay, and the table-section in front of the wire is so tilted as to remove the brick carried thereby some distance from the wire,

so that the wire-carrying frame can be permitted to slide forward to carry the wire away from the forwardly-tilting edge of the brick behind said first mentioned brick. Hence the rear ends of the cams are recessed or depressed along curved lines from the point e to the extremity f, thereby permitting the wire-frame to slide forward after leaving the point 0, allowing the cutting-wireto move upwardly through the cut midway between 11 and be lifted clear of the upper ends of the guide-standards without binding thereon, the cams holding the wire-frame in its reel-slideways until said wire-frame has reached or passed the horizontal position in its upward movement.

As the cutting-wire of each wire-frame is about an eighth of an inch nearer the reelaxis thanis the axis of the guide-rollers 18, it is necessary to incline the guide-standards 11 just as much off the perpendicular as the cutting-wire is off the guide-roller center or axis in order to make the perpendicular cut through the clay barsthat is, in order to cutthe ends of the brick squarely at right angles to the side faces of the brick. It will hence be noted that as the guide-rollers 18 pass down the guide-standards 11 the cuttingwire passes down through the clay bar slightly in advance of the axis or center line of the rollers 18 and that asthe cutting-wire moves up or back through the opening between the bricks it is slightly behind the said axis of the guide-rollers 18. Now the relation of the tracks for the traveling-table-supporting rollers with respect to the reel is such that as soon as the cutting-wire has passed down through the brick into the slot 13 and has started on its return movement the table-section having the guide-standards 11 in engagement with the particular guide-rollers 18 begins to drop from the horizontal position.

This. movement tips the guide-standards forwardly from the perpendicular position, and hence as the guide-rollers 18 travel up said standards the wire-carrying frame is moved forward, so that the wire is carried up clear of and out of contact with the edges of the bricks. The guide-standards hold the frame to prevent the wire engaging the brick surfaces behind the same, while the cam-surfaces hold the frame to keep the wire from engaging the brick surfaces in front.

It will be observed that the bricks are not out between or over the adjoining ends of the table-sections, but that the cuts are made just in rear of the center of each section, so that a little more than half of each brick'rests on one table-section and the remainder of the brick projects forwardly onto the rear portion of the next table-section in front, so that said &

table-section in front can drop down from the brick in passing down on the curved front ends of the tracks without causing the brick to tilt and drop from the traveling table. This arrangement permits the advantageous employment of the inclined receiving-platform hereinbefore referred to, as the receiving end of the roller-platform is so arranged that the front end of each brick left projecting from the section carrying the greater portion thereof by the dropping of the section in front drops onto the receiving-platform and is pushed forward thereon as the tablesection carrying said brick moves down past the inner end of said receiving-platform. As the receiving-platform at the delivery end of the cutting-table is inclined downwardly, the bricks easily slide onto the roller table or platform and are easily pushed forward by each succeeding brick delivered onto the platform by the table.

It is evident that various modifications might be resorted to in the forms, constructions, and arrangements of the parts described without departing from the spirit and scope of my invention. Hence I do not wish to limit myself to the exact constructions set forth.
