ROTARY-CUTTER MACHINE.

SPECIFICATION forming part of Letters l.'E'ate'nt No'. 665,007, dated January 1, 1901.. Application filed September 21l 1900. Serial No. 30.670. (No model.)

T LZZ whom it, may concern:

Be it known that I, ROBERT J. HEARNE, a

citizen of the United States, and aresident of New York, inthe county .of New York and.

State of New York, have invented certain new and useful Improvements in Rotary-Cutter Machines of which the fol owing is a speci- The invention relates to improvements in lrotary-cutter machines; and it consists in the 4table, means yieldingly and pivotallyi supporting said frame, means for adjusting said table and anvil-wheel with relation to the cutiing-wheeland affording an adjustable yielding pressure for said wheels with respect to one another, and means for rigidly maintaining the shaft for the cutting-wheel so that said shaftmay be kept from springing upward during the employment of the machine.

The invention and vsatisfactory means for r carrying the same into edect will be fully understood from the detailed .description hereinafter presented, reference being had t. the accompanying drawings, in Which- Figure 1 is a side elevation of a pinkingmachine constructed in accordance with and embodying Itheinventiou. Fig. 2 is a vertical transverse section of same on the dot-ted line 2 2 of Fig. 1. Fig. 3 is a' top view, partly broken away, ofthe right-hand portion of the machine; and Fig. 4 is a vertical transverse section of a portion of the machine on the doi-ted line 4 4 of Fig. l.

In the drawings the numeral 10 designates the general frame of themachine, said frame comprising tlie'main standard 11, having at its upper end the bearing-sleeve `12, at its lower end thebed-plate 13, and at a suitable distance above said bedplate the arm 14,

vcarrying the vertical. sleeve l5 and at the outer endy connected with said bed-plate'13 by means of the standard 16.

Within the sleeve 12, extending'centrally of the main frame 10, is mountedthe shaft 17, supplied on one end with the gear-wheel 18, which, as usual, is in engagement with the pinion-wheel 19, secured 'upon the yshaft of 5 the power or. driving wheel 20', the said Wheels 18, 19, and 2O being usual in this art for imparting motion to the shaft carrying the cutting-wheel, which inthe present case is desigy nated bythe numeral21 and is removably seo cured upon the shaft 17.

The bed-plate 13 directly below the vertical sleeve l5 is formed with the hollow hub 1 22, which is partly closed at its lower end by the plate 23, (see Fig. 2,) which is fastened t0 6 'the lower side of the bed-plate 13 by means o screws.

Within the vertical sleeve l5 and hub 22 is placed the vertical standard 24, having at its upper end the yoke 25, .which supports the 7o anvil-wheel 26 and work-table 27,`and which yoke comprises the 'transverse base 28 -and vertical arms 29 29, the latter' having the bearing-sleeves 30 30 to receive the pin 3l, upon whichthe anvil-wheel 26'has its movement. '7

`The-vertical arms 29 29 extend-upward above the bearing-sleeves 30 and above said sleeves form the supports 32, upon which the ,table 27 is fastened. The yoke 25 is pivotally mounted by means of the shaft 33 upon the 8o cross-head 34 on the upper end of the vertical standard V2'4, and said cross-head 34 is provided atopposite sides of said standard 24 with the adj usting-screws 35 35, whose points are adapted to contactwi-th the base 28 of 85 the said yoke 25. In the absence of the screws 35 the yoke 25 would be free to have a liberal rocking or pivotal motion upon the shaft 33; but this motion may be limited and controlled` by theadjustment of the screws 35, by which the downward tilting ,motion at either side of the yoke 25 may be either regulated at will or absolutely prevented, as circumstances may require. The standard 24 is guided in its-'vertical movement by means of the sleeve 95 15,-and said standard, with its-cross-head 34, is prevented from having anyaxial movement by means of a pin 36, which', as shown in Fi'g. 1, is secured to said cross-head 34 and passes freely within the vertical aperture 37, formed in the arm 14 of the machine-frame.

I ooA During the vertical movement'I of the standard 24 the pin 36 simply has a sliding motion within the aperture 37 and by being confined within said aperture prevents the standard 24 from turning axially. The vertical standard 24 supports the yoke or head 25, anvil\ wheel 26, and work-table 27, and said standard 24 is in the form of a verticalshaft whose lower portion is threaded, as at 38,- Fig. 2, and receives the nut 39, which has a bearing against the lower end of the sleeve and is formed with the handles, wings, or fingerpieces to facilitate its rotation u pon the threaded portion of said standard 24.

Encircling the lower end of the vertical standard 24 is a firm coiled spring 41, which is seated within the hollow hub 22 and confined at its upper and lowerends by the nut 89 and plate 23, respectively, as illustrated in Fig. 2. 1t will be observed that the spring 41 furnishes a yielding seat for'the standard 24 and the parts carried thereby.

The purpose of the nut 39 is primarily to enable the Vertical adjustment of the standard 24, anvil-wheel 26, and table 27 with respect to the cutting-wheel 21, and it will be obvious that when the nut 39 is turned in one direction it will effect the elevation of the standard 24 and wheel 26 and that when said nut is turned inthe reverse direction the said standard 24 and wheel 26 will be lowered. An important feature in the upward adjustment of the standard 24 in accordance with my invention is that the tension of the spring 41 remains normal until the cutting-wheel and anvil-wheel come into contact with one another and that thereafter the continued ro-l tation ofthe nut 39 in the same direction results in the downward travel of said nut on the standard 24 and against the spring 41, whereby the force of said spring is brought under absolute control, and there is afforded an adjustable yielding pressure without regard to the special diameters of the'wheels or the distances their centers may be apart.

The cutter-wheel 2l is held upon the shaft 17 between the adjoining endsof sleeves 42, which are slipped upon the outer'end of the shaft 17 and are there held by means of the nut 44, screwed upon the outer extremity of said shaft 17, as shown in Fig. 1. The sleeves 42 and cutter 21 may be slipped from the shaft 17 upon the removalof thenut 44 from the latter. I make use of a series of sleeves 42, so as to readily adapt the shaft 17 for re ceiving the cutter wheels 21, varying in width, and also to facilitate the securing of the cutter-wheel 21 at any desired point over the anvil-wheel 26. Cutter-wheels 21, varying in their patterns and widths to considerable degrees,are employed in this art, and

'by the employment of the sleeves 42 any of said wheels maybe readily secured in the desired positions upon the shaft l7, said cutter-wheels being clamped by the pressure of the nut 44 between adjoining ends of the sleeves 42. The sleeve 12, receiving the shaft 1 7, is of considerable length and affords along bearing for said shaft; but at its outer portion said shaft 17 may bc liable to spring plain that the upward slightly under the force exerted by the anvil-wheel 26 when the machine is in use, and to overcome any such result I provide the stirrup 45 and bearing-block 46 to engage the upper surface of the outer end of' said shaft and hold the latter against any undue upward yielding. The stirrup 45 has a eoncaved lower surface to lit upon the shaft 17 or the sleeves thereon, which in effect form a part of vsaid shaft, and said stirrup 45 is yformed or secured upon the lower end of the vertical threaded stem or screw 47, which passes through apertures in the arm 48 of the machine-frame and is engaged by the internally-threaded nut 49', which has a milled periphery and is confined between the portions 50 51 of said arm 48, asshown in Fig. 1. The rotation of the nut 49 by means of the fingers will cause the screw 47 and stirrup 45 to have a vertical movement, and thus it is operator may upon observing any upward yielding of the outer end of the shaft 17 cause the stirrup 45 to move downward against said shaft. The bearing-block 46 is likewise concaved on its lower surface to engage the upper surface of the shaft,17, and said block 46 is carried on the lower erfd of an adjusting-screwl 52, which engages a threaded aperture in the cross-bar 53 of a yoke 54, which is pivotally secured .by a pin .55 to the bracket 56, the latter lbeing securely fastened to the standard 16. The yoke 54 is shownin its operative position by full lines in Fig. 1, and by dotted lines' in Fig. 1 the yoke 54 is shown in the position it will occupy when turned downward from its vertical position to entirely relieve the shaft 17 and completely open-the space intermediate the lower surface of said shaft and the upper su rface of the work-table 27.` The bearing-block 46 is capable of vertical movement under the operation of the screw 52, and when. moved downward'against the shaft 17 will aid the stirrup 45 in preventing any upward yielding of said shaft. When itis desired toplace the cutter-wheel 21 and sleeves 42 on the shaft 17, the stirrup will be elevated by means of the nut 49, and the bearing-block 46 will at such time also be elevated and the yoke 54 turned downward to the position in which it is shown in Fig. 1, thus leaving the shaft 17 entirely free to receive the cutter 21 and sleeves 42. After the cutter 2l and sleeves 42 have been placed upon the shaft 17 the stirrup 45 may be lowered and the yoke 54 returned to its vertical position, uponreachingwhich it will support the bearing-block 46 directly over the shaft 17, and thereupon the said block 46 will be lowered by the operation IOO IIO

of the screw 52. The yoke 54will remain in position, so that' the outer edges of the fabric l may hang outward from the eud of the worktable 27 in an unobstructed manner while the inner edges of the fabric are passing between the cutter-whee121 and anvil-wheel 2,6; When narrower pieces of fabricA or material are being treated, the yoke 54 will remain in its vertical position, since at such time there gage 57 for the passageof the fabric.

may be shifted along said work-table 27 to suit the varying conditions lwhich may arise with respect to the fabric to be treated. It

will be observed upon reference to Fig. 1 thati the sleeve 12 is of considerable length and is above the right-hand portion of the work-table 27, and that hence a large amount of space in a longitudinal direction is provided above the work-table 27 to receive and permit the passage of the fabric to be treated.

The construction of the frame of the machine is such that I am permitted yto employ a table 27 of extended surface area, said tale extending from the yoke 54 to the sta-ndard 11 and affordingconveuient surfaces over which the fabric may be fed andguid'ed. The

table 27 is, as above described, secured upon the upper ends of the arms 29 of the yoke or frame 25, and, as shown in Fig. 2, the said table 27 projects forward toward the operator to a suitable extent to make .it an easy matter to properly feed the fabric between the cutter-Wheel 21 and anvil 26.

In the operation of the machine hex-einbefore described power is applied to the wheel 2O and the fabric is fed upon the table 27` and between the cutting-Wheel 21 and anvil- Wheel 26 said cutting-wheel and anvil operating in a well-known manner. The relation of. the anvil-wheel 26 and table 27 with re- Spect to the cutting-wheel21 is governed primarily by the nut 39, by which the said anvil-Wheel 26- and table 27 may be moved toward or from the cutting-Wheel 21 at will and without altering the relation of said anvillvheel and table to one another. The yoke or head 25 carries both theanvil-wheel 2G and table 27, and hence said wheel and table move together. The adjustment upward of the standard 24 by means of the nut 39 will have no effect upon the spring 41 until the 'anvilwheel commences to bear against or meets the resistance ofthe cuttingwheel, and then should the rotation of the nut 39 in the same direction be continued'the compression of the spring 41 will take place and the yielding pressure of the anvil against the cuttingwheel will be increased. When the -anvil- Wheel is moved upward until it simply reaches the cutting-wheel, there exists anormal yielding support furnished by the spring 41 in its lproper relation to the anvil-Wheel 26. cases, however, the nut44 should press against initial condition; but any further rotation of the nut 39 inthe same direction will increase the tension of the said spring, and consequently the force with which the anvil-wheel will press against or toward the cutting-wheel, the degree of its tension or force being subject To the manual movement of the nut 39, and .consequently is adjustable to meet varying conditions and under the positive and convenient control of the operator. Thus the spring 39 affords when under pressure a yielding resistance to one of the wheels which coperate to effect the cutting of the fabric, andthe nut 39 may be utilized to first secure the primary adjustment of said Wheels with respect to one another without regard to o r affecting said springand then to 'apply pressure to any extent desired'against said spring, g

whereby the tension of the latter, and consequently the amount of its resistance,V may be adjusted or regulated at will under the positive control of the operatoin The spring41 has no fixed connection with either` the cut.

ting-wheel oranvil-wheel or with the parts connected to move therewith, and conse-y Vment of one of said wheels toward the other thereof, and hence said spring may be independently adjusted to any ,extent desired and affords a very'desirable adjustable yielding resistance forthe wheel against which its force is exerted. i

During the employment of the machine the yoke or head 25, table 27, and anvil-wheel 26 may be permitted to have a slight tiltingmotion on the shaft 33.in accordance with the special. character of the cutting edges of the wheel 2l, the fabric to be treated,l and other circumstances, and thereby'the machine is rendered Ymore eicient and'made capableof a wider range of employment. When the machine is in use, the outerend of the driving-shaft 17 is prevented from springing up- IOO IOS

ITO

on the shaft 17 it will be necessary to omit some one of the sleeves 42, so as to provide adequate space upon said shaft for the wider cutter-wheel. rlhe sleeves 42 vary from one another in length, and this is for the purpose of permitting the shifting or transposition of said sleeves to accommodate theI varying widths of cutters and to enable the operator to locate the cult-er or cuttersemployed inv In all preventing the upward yielding of the outer end of the shaft 17, except when the width of fabric to be treated is such as to require the yoke 54 being left in its down position. (Indicated by dotted lines in Fig. l.)

In many instances it is desirable to employ two cutter-wheels 21 on the shaft -17 for cooperation with the anvil-wheel 26, and owing to the ixnpracticability of having the two cutting-wheels absolutely concentric with one another it is substantially impossible to attain the best results'with a rigidly-mounted anvil-wheel 27, and hence I provide the tilting yoke 25 for supporting the anvil-wheel and in the use of the machine permit of the tilting or dipping motion of said yoke and an vil-wheel as thecutters pass over the same. When two cutters 21 are employed, they should be located as nearly as possible at equal distances from a vertical central line through the anvil-wheel 27. j
