at a point near the forward cud, are placed `the adj ustin g-screws of the blocks and securing the flanges to the lcarriagefby suitable bolts. The blocks (1 are formed with channels in their outer faces intowhich the guide-flanges of the standards pass. To form a close contact between the flanges and blocks, suitable'packing-blocks` at diierent points and equidistant apart.'

These holders consist, primarily, of two members, the stationary or base member 7iy and .the adjustable holding member K. The base members h are formed with flat under faces resting on the carriage, their outer vertical sides being formed with shoulderslt?. centers of 4the members h are formed with longitudinal channels 7L", which are deepened at their outer' ends at h, and at their forward ends terminatein t-he slots h5, leading throu gh the base. In the lower wall of the channels,

h, entering sockets in the wall. j

H designates a transverse cylindrical shaft spanning the channel and loosely journalcd in the side walls thereof at a point adjacent t'o the outer ends of thcvmeinbcr.

The tool-carrier or movable member 'K consists of a solid block having an inclined recess 7c in itsj inner end, open :It its top and terminatingata pointV near the base ot' Ine block, thus forming a lip k', througlrwhieh the inclined adjustingserew 7.12 passes into the slot', and projects into the slot of thc base member. The rear end ot the block l is recessed transversely, as at It, and receives plate.

the shaft H'. of the block.

To adjust the block K longitudinally, the screw L is employed, which passes through a threaded aperture in the shaft Il".

L' is' a backing-plate removably secured by screws Z to the outer end of the bloei: covering the open end of the recess. 'l.`hrough this plate passes the outer cud of the screw L, a suitable collar L2 being secu red on the screw and abutting against the inner face of theY The outer end of the screw L has a disk L thereon, which is preterabl y This recess opens to the end turning formed with cavities Zifor the reception ol' the lturning key or pin. (Not shown.)

To limit the upward movement ol the outer 0nd of the block K, a cross-bar lm is bolted on the rear upper edges ot the base h, spanningl thespaee between, and against which the block rests.

'-An vimportant feature of the invention the cutting-tool O, which is rectangular and formed lwith a working face. having a series of vertically-arranged teeth or ridges o cx tending from end to end. The upper end of the tool is beveled or inclined, and when the it in position.

The l tool is adjusted in its groove or inclined recess 7a the top ofv the tool will bc'lush with th g top of the block K. the cutting-tool, binding-screws o' are passed through the side walls of the recess k, which impinge against the-sides of the tool and hold The base of the tool rests against th'e adj Listing-screw 7c?.

To center the tools, the -lower members of the holders are properly arranged and the triangular plates P are placed between, resting on the flanges or shoulders 7l?, and suitable bolts are passed the carriage.

f In operation the roll (.2 is adjusted yby cenin the arbor to the arbor.

tering the centering-pins C I) thereof and clamping the arm D5 To properly adj ust 7o through thc plates into 'Qq r The roll is thus held firmly against vertical as well as rotary movement. The water is 'theuturnedin to the cylinder, forcing the piston up, which in turn forces the tool-e rriagc upward, the tool having been previously adj usted to cut the grooves in the periphery of 9o the roll as the upward movement of the car-A riage is continued. As soon as the lull stroke of the piston is reached the valve for the cylindcr is by any suitable means adjusted, al-

lowing the water to escape and the carriage l to descend by its own weight as the water rcccdes. In descending the tool-carrying blocks swing up on the pivot-shafts 1I and thereby oder no resistance to the downward movement of the carriage. As soon as thc car riage has reached its lowcrmost position thel roll given the proper tra thmll' m Il* ltrunientalty ol the worin-gear and the operation repeated. Shoulda tool bccomc'brokeu IOS or dulled atits cutting-point, it is only neceslor sary to grind oit the upper beveled end, and this can be repeated until thc tool is pra-ctically destroyed. By this means the tools can be quickly sharpened. with but slight trouble and.c.;'j cnse. rlhc adjusting-screws on top of which the tool rests can be adjusted when the. holder is in position by inserting the proper' tool inthe slots hi ot the stationary member 71 which latter normally projects bcyond the inner wall of the carriage, as shown iu Fig. 'lhe purpose ot the adjustingscrews h is-to secure thc proper arljustment of the inner ends of the blocks l.

liy arranging the tools in a circle around the roll every upward movement' of the carriage culs not less than eight grooves or corrngations in the ,roll tothe proper depth. The depth of the corrugations may be easily varied by adjusting the screws L to carry the tools in or out, as the case may be.

l am aware that the means for vertically moving the carriage maybe varied, and do not wish my invention understood as being limited to the particular hydraulic lne'ans shown and described.

I am also aware that many other changes in the various forms and arrangements ot' the parts of the machine can be made and substituted for those herein shown and described IIO without in the least departing from- .the nature and principle of my invention.

Having thus fully described myinvention, what is claimed as new, and -desired to be se-l cured by Letters Patent, is-

1. In a eorrugating-machine, the combination with means for supporting and holding the roll in a `fixed position, of a vertically-reciprocating 'carriage through which the roll passes, al circular series of horizontally-pivoted tool-holders mounted on the upper face of the carriage, means for adjusting the holdersradiall-y,I and means for forcibly moving the carriage upward across the surface of th roll, substantiallyfas described.

2. In a corrugating-machine, the combination 'with means for ixedly supportingthe roll and means for holding the roll in position,

'of a carriage having a central bore greater .han the diameter of the roll, means for forcibly moving the carriage upward across the face of the roll, guides for the carriage throughout its entire movement, a radially-arranged series of horizontallylpivoted tool-holders mounted on the upper face of the carriage, 'tools in the holders, and means for radially adjusting the holders, substantially as described.

3.- In a corrugating-machine, the combination with vertical standards and roll-supporting means at opposite ends and between the same, ofa ring-shaped carriage between the standards, guide-blocks on the carriage engaging the standards, a hydraulic cylinder below the-standards, a piston in the cylinder,

-posts on the piston supporting the carriage' at their upper ends, and a circular series of horizontally-pivoted tool-holders on the upper face of the carriage having tools projecting into the open center of the carriage, substantially as described.

and adjustable tools'earried by themmfableV member', substantially as described.

8. In a corrugating-maehine, the combination with a tool-carrier, of a tool-holder comprising a stationary member having an open center and a transverse shaft spanning the opening, and a movable member pivoted on the shaft and formed with a recess in its outer end and an inclined recess at its inner end, a removable tool in the inclined recess, means forsccuring the tool in position,'and means for longitudinally adjusting the movable member, substantially as described. f

9. In a corrugating-maehine, the combination with a tool-carrier, of a tool-holder thereon comprising a stationary member having a channel therein and a slotted inner end, and a movable member loosely fitted in the channel having an inclined recess at its inner end open at its upper' end and closed at its lower end, a set-screw passing through the lower wall of the recess into the slot of the stationary member, a tool clamped inthe recess, andv IOO member en the stationary member engaging the pivot, substantially as described. f"

ll. In acorrugating-macliine, a tool-holder comprising a stationary member and a movable member loeated within the stationary member and formed with a recess in its outer end, a horizontal shaft on the stationary member passing through the recess, a screw in the movable member held from independent longitudinal movement therewith and engaging the shaft7 and a tool in the opposite end of,

the movable member, substantially as described.

In testimony)vhereof I affix my signature in presence ot' two witnesses.
