To all whom it may concern -,,Be it known that I, JAMnsGnonoE ADDER-.-

son, a citizen of thenUnited; States,..residing at Renton, in the county of King-and v new and. useful v Improvements, in, Erick making-Machines, of which thefollowing 1sg 1 This invention relates to, impr vements i machines for making paving brick.

A disadvantage heretofore attendantupon side-cut brickhasbeen that it hasnot been. practicable to form .the longitudinal beveled edges or form the'sidelegs for spacingv the .Zvide. devicesv for the accomplishment of such refinements to the brick that this application deals.

Qne of the objects of the inventlon iszthe 1 provision of automatiomeans for raising .side spacing 'lugs upon one or.,both of the .,side. out edges of. the clay. blocks.

A further object of theinvention istheprovision of automaticmeans for. forming" beveled or rounded corners uponthe upper livered from the cutting table.

an axis extends transversely to the direclater'al. sides ofside-cut clay blocksas de- .A.still further object ofthe invention consists in the provision of means of simple construction and eflicient. operation for turning side-cut clay blockswherein their longitudithe provision of means to advance a column of clay blocks arranged in end-to-end relaline of travel. sa1d apron thelr rearmost ends are inter .clay-blockrforming apparatus with the above .objects in view, as will be fully described in thefollowlng specification, illustrated in the accompanyingdrawings and finally set forth in theappended claims. v I BBIEGIII'IIIg to said. drawings, Figure 1 is a. v ew 1n side elevation of clay-block form- .ing apparatus embodying my invention.

.Fig.2.1s a plant-view of the. same. Fig. 3 is transVerse==secti0nal view on lines 3-3 oifiFig. 1. -.Fig. 4 is a similar view on lines Hot-Fig. 1.: Figs. 5-and 6 are detached perspectiveviews of details. ofnthe. inven .tion. gFig. 7is a-.persp.ective view of a ,finished clay-blockas produced by the apparatus illustrated.

;-.Referring to the. drawings throughout which like reference numerals indicate like parts, 1 is the discharge end of a cutting ,table upon which a column of clay is cut into ;blocks or bricks, B, the cut surfaces forming -:the .lateral or. side edges of the finished brick, and the major axis of the brick being transverse to the longitudinal axis of the cuttingtable and toqthe direction of travel ofthe clay column, and 2 is a platform over which. the blocks B are moved before being deposited on an endless belt or apron 3. Said .apgron is operatively mounted .upon suitably driven. pulleys 5;and 6' supported in a table :OIifI'iLIHG at and itsupper portion is caused to travel in'the direction of the arrow in Fig. 1 at a .h1gher-..rate of speed than-thespeed of travel of the advancing column of blocks,

whereby the blocks are automatically separated to allow for the turningmovements to be-.-presently described.

The platform 2 is formed with one side cutaway so;that one end of each block is deposited upon said moving apron 3 before :the .opposite end is pushed beyond its supportuupon thepportion 2 of the platform, whereby the first-mentioned end ofthe block is carried forwardly of its opposite end and thus travels for a distance upon the apron in an oblique position with relation to its As the blocks advance on cepted by a suitable idle turning roller 7 which is rotatably mounted with a'vertical axis at the side of the path of said blocks and retards the motion of the rear end of said blocks sufficiently to cause the same to have their major axes directed in alinement with the longitudinal aXis of the machine frame and directed to enter endwise between the side guide- rails 8, 8.

A transversely arranged idle roller 10 may be added, mounted in the frame beneath the upper portion of the apron 3 having a circumferential ridge, indicated at 11, which engages the underside of said apron and upon which the middle portion of the advancing block rests when the rear end thereof is intercepted by said roller 7. The ridge 11. thus affords a medial pivotal point upon which the block is readily turned. The clay blocks move progressively forward upon the apron and are therefrom deposited upon a polished metal plate 12 whereupon they are slidably advanced in a continuous end-toend column by the frictional contact of the moving blocks resting upon the apron 3. The blocks upon the latter are at first spaced apart but toward the forward portion of the apron between said guide-rails the resistance of the moving column of blocks upon said plate 12 causes them to close up until the accumulated frictional hold of the blocks upon the apron is sufiicient to push the column forwardly upon said plate.

Corner beveling knives 13, 13 are adjust ably positioned in holders 15 rigidly mounted in posts 16 at each side of said moving column of blocks and adapted to make a shearing inclined cut along the upper longitudinal edges'of the blocks forming the beveled corners 17, as clearly indicated in Fig. 7.

18, 18 indicate ridge-forming tools adjustably secured in vertical spaced .relation in posts 20 and projecting into the path of said moving column of blocks for the purpose of raising parallel ridges 21 upon a lateral side of the brick. Said ridge-forming tools may be of any suitable construction but, as utilized and illustrated, each con sists in a shank 22 having at its outer extremity a pair of spaced thin-edged converging pallets 23 adapted to be engaged by the plastic material of the blocks and mold the same into a raised ridge, as described. As the column of blocks advances upon leaving said ridge-forming tools, it is engaged by a roller 25 mounted with a vertical axis of rotation and adapted to resiliently bear upon the side edges of the blocks upon which the ridges were formed and flattening said ridges approximately to the normal plane of the block edge. Said roller is formed with a plurality of vertically arranged grooves 26 spaced symmetrically about its perimeter into which the ridge material impresses to form lugs 27 projecting from the side Wall of the block. Said rollers, as illustrated, are pivoted at 30 in swinging arms 28 and yieldingly pressed against the column of clay blocks by means of a tension spring 81. The blocks are then discharged from the plate 12 upon a conveying apron 32 and conveyed where desired.

Having described my invention, what I claim, is-

1. The combination with a machine for forming brick blocks of a ridge-forming tool, said ridge-forming tool having two converging curved blades that are disposed to enter the face of a soft brick block to form a ridge thereon.

2; The combination with a machine for forming brick blocks of a ridge-forming tool having converging curved blades adapted to enter the face of a soft brick block to form a ridge thereon and a grooved roller to compress portions of the ridges formed by said ridge-forming tool and produce lugs on the face of said blocks.

3. A. machine of the class described comprising a moving apron upon which brick blocks are advanced in side to side relation, a transverse roller beneath said apron, said roller having a circumferential ridge that forms a pivot for advancing brick blocks and a device for engaging one end of said blocks to turn said blocks into end to end relation.

4:. A machine of the class described, comprising a platform over which brick blocks are moved in side to side relation, said platform having an angular discharge end and an apron to receive said blocks, said apron being movable at a speed. greater than the speed of movement of said blocks, whereby said blocks are turned into an angular position as they are delivered from said platform.

5. A machine of the class described comprising a platform for brick blocks, said platform having an angular discharge end, a moving apron upon which brick blocks are delivered in an angular position, a transverse roller beneath said apron, said roller having a circumferential ridge that forms a pivot for advancing brick blocks, and means engageable with an end of said brick blocks to turn said brick blocks in end to end relation as they pass over said transverse roller.
