' .tlpplication filed June 20, 1919. Serial No. 305,510;

Z T0 (1Z6 whom it may concern tie it known that. I, MEnToN T. STRAIGHT,

a citizen of the United States, residing at Adel, in the county otDallas, State oflowa, have invented a Machine for Corrugating iflasticlilocks, oi. which the-following is the specification. r

This invention relates to improvementsin clay Working machine'sandparticularly to those designed to corrugate the ends of tile and hollow building blocks. .Heretobefore the tile,and,buildingblocks have been cut withcomparatively smooth ends. I i-drain tile is desirable to corrugate orgroovethe ends to per nit water to'fiowimore freelybe tween the adjacent, endswhen laidgin. the ditch. In building blocl zs'it is desirableto corrugate or groove the jendsxto ,pern1it the mortarand cement to adhere more firmly, when the blocks are laid-in a wall;

The object otiriy invention is to provide a machine of simple, durable. and inexpensive construction adapted to automatically fOI'ID QlOOVGS or corrugationsin the ends of blocks, formed of plastic.Inaterial.

A further objectis to L provide in. connection with abeltffor conveying plastic blocks, means for automatically corrugating the up per. and lower ends of the bloclc carried thereby. I r r Y r A further object is to provide in a device for corrugating plastic blocks carried by a conveyor belt, new and improved means vfor timing" and driving the devices from said belt.

A Still "further object is to provide in a device for, corrugating plastic blocks by means of spaced corrugated rollers, improved means for preventing the plastic material from sticking to the grooves in said rollers as they are being operated.

My invention consists in the construction.,- arrangement and combination of the various parts of the device whereby the objects con-.

templated are obtained as hereinafter inore fully set forth, pointed out in my claims and illustrated in the accompanying drawings in showing the manner in which the blocks are conveyed between the rollers.

in the illustration ofiny lnventlon dlsclosed, 1n theaccoinpanylng drawings, I have used the reference numeral 8. to indicate parallel supporting vmembers provided with legs 9and connected togetherby means of transverse members 10. Each ofthe side meinbers 8 is provided witha notch 11 inlits R'otatably moiinted Lin each end :of the "members Sis a shaft 13, each of which is de signeil'to carry. a pulley wheel l4,one of the shafts 13 being extended laterally from the sideof the frame and provided withabelt provided at substantially equidistances between the'rollers 16 and the pulleys 14. Rotatably n ountedflat point below and between the pulleys 16 is a shaft 18, one end of which is provided with a belt pulleyli).

A gear wheel 20 is secured tothe shaft 18 adjacent to the inner: side of [one of the members 8. .Secured to one end of the cen tralportion of the shaft 18, I have provided a disc 21 provided with a series of laterally egitendingbars 22 which are spaced apart and arranged parallel to each other andparallel with the shaft 18. Theopposite ends of the bars 22 are held inposition relative to each other by means of the ring 22. Secured to the shaft 18 inside ofthe bars 22, I have provided anauger 23, of sucha diameter as to engage the bars 22. These bar-s22 and disc 21 forni a drum, the purpose of which "will be more fully set forth.

Mounted upon the pulleys 14,1 have provided a belt 23, the upper run of which is, designed to rest on the upper sides of the rollers 17 and extend downwardly between the rollers 16 and beneath the drul'n formed hy'tlre bars 22. For sake of convenience, I shall call this drum a driving pulley.

Secured to the outsides of one of the mem- Y bersS and extending across the opening 11, I

have provided a barQd held in position by means of bolts 2&1, (Fig. The bar 24 is provided with an upwardly"extending area "eat member 26 having a bearing 27 at its upper end, amlat the intersecting portions of the biirs 24 and 26 a bearing 28. Secured to the opposite member 8, I have provided an up- 5 right member 29 somewhat similar. to the member 26 and provided at its upper end with ithe beari 31 and at its intersecting portion provide the lower side of which is provided wit the shelf flo: V

Botatably mounted in the bearings 27 and 31,I have provided a shaft 33 having on dhefefid a pulley wheel 34. This pulley 34 ls inline with the pulle wheel 19 before mentioned. Secured to t e central portion ofthe shaft 35, I have provided a cylin- =di'um 35,the periphery of which is pi'pvided with teeth or grooves 36. These teeth iii'efcomparativel close together and tticteiidjcircumferentiall ffThe j drumis Iformed hollow and provided with s oke's 36,"- the ends" being otherwise ogpen. has it will be seen I have provided z gf hdllow space through which heated air Y he'conducted hy means of any connie nj burner such as a blow torch and inafiteby'the numeral 37.

otatablymounted in the bearings 28 g ave provided a some hat sim 'h d r, rum than the one indicatedby the nitrates, ass d of which is provided th a ar 39]. This gear39 is designed to p, the, gear 20 before described; A 35, similar 'to 37, is employed for lta tipg thisdrum 3,180. A belt 40 is operatlveljflmounted upon the pulleys 19 and 34.

hijbperation, assuming that the belt wheel 2 is connected with" suitable power and is 40 rotated, and that the tile or blocks are f beitigflplaced upon the belt 23", by hand or otherwise and ma vertical position, it will be seen that thesaid belt will be rotated and meadows direction as indicated by' the ar- 5 row. The rotation of the belt 23 willcause thedriving drum 21 to be rotated and the gears 20 and 39 rotated. The tile or block thereon will also be advanced toward the drums 35 and 38, This will cause the upper to; face of the drum 38 toberotated in the same direction "as the horizontal portion of the belt 23. "The drum 35 will also be rotated in the opposite direction from the drum 38 means of the belt 40, the peripheral speed 55, of the drum 35' and 38 being substantially equal to that of the belt 23. Thus it will be seen that as the said belt and drums are 1'0- 1 tated, the tile or blocks 44 will be advanced and caused to J travel between the drums 35 and 38. The distance between the said i drums is substantially equal to the length of the blocks, parallel grooves 0r corrugaytionswill therefore be formed on the ends of the plastic tile or blocks.

They areso arranged that the air within the drums will film of steam to be generated when engaged by the moist material. This steam prevents the material from sticking to the teeth.

To prevent the driving drum or roller 21 from lapping or windin with the fragments of the soft material, have provided the slats 22. These will permit the material to be forced between them which will be moved means ofthe auger 23as'it is rotated. 30 Thus it will be seen that I have provided a machine of comparatively simple and inexpensive construction adapted to corrugate the ends of Iclaim:
