To all whom itmay concern: i v
Be it known that We, JOHN WOLF, Jr.,and'
JACOB BLOCH, citizens of the United States, residingat Cincinnati, in the county of Hamilton and State of- Ohio, have invented certain new and useful Improvements in Ololh- Cutting Machines; and we do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will-enable others skilled in the art to which it appertains to make and use the same.
This invention relates to machines or instruments for cutting textile fabrics and other materials, but more particularly to aclass of machines used incutting out cloth suitsand other clothing. Machines of this character have heretofore been devised, in some of which it has been re sed to employ a rotary cutter ournal d ib a upon a standard that rises from a foot-plate and supports a rotary air or steam-actuated motor and driving gearing for imparting mo tion to the cutter, its way through the cloth as the machine is moved forward by the has also been proposedto employ electric. mo-
knife, and also to drive a rotary cutter, by meansfof belts and pulleys connecting. the knife-arborwith the motorshaft or witha driven shaft connected-by jointed arms and intermediate driving 'gearing with a station-y ary source of power. Thelatter class of machines is subject 'to-objection, for the reason that only a limited movement ispermitted and the machine andits actuating mechanism are more or less complex, cumbersome .andexpensive, making the initial cost of the machine considerable and increasing the cost of maintenance by frequent renewal of parts of the complex structure, The machines in whichan air or steam motor is employed are i also objectionable because of their bulk and unwieldiness and their motion is irregular and thumping,rendering it difficult to control the movements of the machine so as to cut the cloth according to the desired pattern. The electrically operated machines carrying reciprocating knives are also objectionable or similar reasons; such machines being nop= heavy and unsteady in operation, producing expensive and smoothly frame mountedso that the latter may cut hand ofthe operator with the foot-plate underneath the cloth. It
a reciprocating wherever belts and pulleys are employed it is difficult to insure a regular and smoothcut,
owing to the liability of the belts to stretch, slip and break, and alsoto cause the machine to become clogged by small particles of the cut fabric adhering ,to the belts.
The objects of our invention are to overcome these several difficulties and to provide a comparatively light, simple, compact, in-
running machine,
which may be moved freely about the table. in any desired direction, and readily lif'ted' from table to table, and which in operation will produce a smooth easy running out, and
the contour of the pattern or the sinuous lines or marks upon the cloth without liability to clogging or miscuttiug by reason of any irregular or tremulousmotion; e 4
With these and other objects in view the invention consists in certain improved features of construction and combinations of parts all as will be hereinafter described and particularly pointed out in the claims at the end of thisdescription.
Referring by letters of reference to the ac: co nt anying drawings whichform a part'of it specification, Figure 1, represents .a side elevation, on a reduced scale, of a cloth cuttingtmachineembodyingourinvention. Fig.

Similarletters of referenceare usedto denote sirnllar parts in each of theseveral-vievvs.
l-Milenotes standard B, which may be formed integrally therewith or secured thereto in any proper mariiler. The foot-plate Ais preferabl y rect-. angular inform and provided uppersurface or top, and the standard prefably rises therefrom at the interseotionof two modification ofthe foot-plate, and Fig. 7 is-el horizontal lines crossingeach' other through a foot-plate from whichrises the with a plain 2 I senses the longitudinal and transverse center of the giirtenhut at one side of such longitudinal. line and with its front edge in ad vence of such transverse line, so as to piece the standard 5 mainly within the space comprising a quad--v rent of the plate, and thus provide aplain surface of less extent uponone side and in front of the cutter than atthe opposite sideand in rear of the standard, sons to afford'an IO extended. and even surface on that side of the foot -plate which is beneath the main body of the cloth; the out portion being turned aside by the standard-as the cutter advances. Thestandard 13, which-supports the rotary cutter and its actuating mechanism, maybe formed with a plain inner face and front curved and beveled edge I), while its outer. face or side is slightly'inclined toward the rear, and it has upon its rear edge an inwardly project 2o ing lip or flange b (Fig. 7) which overlaps the rear edge of the rotary cutter C, as indicated in dotted lines in'Fig. 5-, so as to protect the cutter and prevent the hand of the operator or the cloth from coiningin contact therewith when the machine is moved in a heckward direction. The standard B may also be formed or provided with a laterally'projeching split portion orclainpB'at its upper end, having a vertical-opening thereth rough to receive the post D. The post D supports the framing which overhangs the foot-plate at one side and has .mounted thereon the else this motor-M, and the mechanism connectedtherewith for imparting motion to the rotary 5 knife or cutter. Said post is adapted to slide ye'rtically through the opening in the clamp B when the binding screw 1) is loosened to permit the bifurcated portion of the clamp re.
be spread apart suficiently to release the no post. This adjustment may be secured by means of a screw threaded rod E upon which -is fitted eninteriorly screw threaded bevel wheel F fitting within and resting .upon the hnseof a socket or recess 21 formed in the 5 clamp B, and meshing with e similar bevelwheel F fixed on n stud i or spindle j which has its hearings'in one of the arms of the clamp B, and is provided with a. square or polygonal end'f' 'to'reeeive n wrench for the purpose of rotating the stud. The upper end.
. or the rod E is secured'to n cross-piece of the "mnin frame which is adapted to rest thereon.
By ihisineans, when the hovel-wheel it is re.- Aa'ted a rotary movement will he impel-ted to the bevel-wheel F, and as the latter is screw threaded upon the rod E the rod will move up or down and raise or lower the su perstructure,.together with the rotary 'knife and its actuating mechanism; the clamp B being 6 we. toperinit the post D to rise or fall by loosening the binding screw b. In this manner every nice adjustment of the rotary knife thi he accomplished as its cutting edge canes worngnn'd. the. adjustment may he s nnt'de with very little expenditure of tinie, merely thing the screw 15 end giving the stnd j thcdesired nnmher of terns, end again tightening the screw so his to clamp the post nndrod firmly in the desired positionnpon the standard.
G, denotes e, cloth-fitting plate or shoe hav-v ing arectangnier or other suitable opening therethrongh corresponding with the angular or other shape of the foot-plate which it is adapted to receive, and about which itis loosely fitted so as to permit a free vertical movement of either the foot-plate or the cloth lifting plate, within certain limits, without disconnecting the parts; "the footplate being outwardly and downwardly from the footplate, the inclination thereof being preferably rather steep, while its ends, or heel and toe gf, g, are gently inclined downwardly, and rearwardly and forwardly, respectively, from the foot-plate; the toe g being lengthened so as to provide a very gently sloping surface in advance of the cutter. I
The cutter C; may be secured upon an ar- -hor. c, which haswits. hearings in eeieere or casing H progecting from the depending pertion of the casing I secured at one side ofthe frame; the outer end of the sleeve being secured to a depending arrh K of the frame. The eleeve'His provided with ahinged cover htor the introduction of lubricating material. The arbor c passes'through an opening in the cutter and through the sleeveH into the'casing 1, and is secured by a not on its inner screw-threaded. end. Within the casing it carries a pinion c which meshes with a driven spur-wheel L which is fixed upon an arbor or spindle jonrn'aled in suitable hearings attached to the casing I. An oil cup Lmayhe provided at the inside of the casing; said cup haring'a snitnhle opening and cover to permit the introduction of oil or other lubricating Byhonsing the gearing which irnpnrts motion to. the cutter within the inclosn. ing' casing, as shown, the hearings-inlay he material.

The motor hi may he of any-approved con struction, though preferably of the form shown, which illustrates in well" known type of motor, and innsinuch as the construction or the snnieforins no pert of our-present in ventiome specific description thereofiis. not deemed necessney herein. The motor-M may be mounted as shown I e :the machine ovee-the rotary cutter"C-,at the arranged the driving the c'uttenso'as tosses 1 a point on iii-perpendicular line cutting the rear edge'ot' the knife. As will be seen, the; armature shaft of themotor and the shatts'of' the rotary cutter and grindingdisks'extend.

The armature shaft N may hay-itsbeariugsl in suitable boxes n, wi one of which is secured to the inner side of the casing I ,and the other to a cross-piece'O attached ,to the field magnets as shown in'hig. I j
In cutting different kinds of cloth-the edge of the cutter wears more or less rapidly, ac-v cordirig, tothe character of the'cloth, and to retaina sharp edge upon the cutter it is nee-- essary to provide a sharpening device by "which the cutter may besharponed while the machine is in operation.
Ithas heretofore been proposed to provide sharpening devicesin which a grinding wheel orwheels are held normal i y in contact with the blade, and provision has also been madefor adjusting the sharpening wheel in relation to tliecutter, but in order to-seoure such ad ustthem: it is necessary to stop the machine and make the adjustment by means of a wrench or screw driver, thus necessitating considerable loss of time. To overcome this objection and at the sametimc tolprovide a simple and elficieht sharpening device, we have devised means whereby an instantaireous ad ustmont may be accomplished by sun-piy turning a "a stud or pin qiFig; 3) projecting :side of the casing I, pinion which meshes with a bevel-wheel L" upright portion of an angle-bard, V a be sleeved fastupon' the inner end of the sleeve thumb n ut, so that during the operationof e ut-- ting the operator may readil adjust the grinding disk or 'disksin relation to the blade, so as to grindmoreor less rapidly according to the rapidity with whichsthe cutting edge is worn of the-character oftheclothwhich istheingcu t. The mechanisn for this purpose may be constructed as followsi-p-P denotes a sleeve projecting in an ohliquedirection to the axis of the'outter froma hinged bracketarui'Q, one end of which is fitted'to turn upon I from the inner SidB'O'f the casi'ngl, and its opposite freeiend is. adjustably secured to the casing by a set-screw'ortap-bolt g. which passes through a curved slot q'iin the arm into 'a threadedopening therefor in the casing.

S denotes a tension-rod which through openings inlthe arms 8,5 and is providedwith' a thumb-nut s at one-end and a head or nut at the other so as to permit a lim ited movement of the bars S, S, toward or from each other;fthe thumb-nut 3 being passes loosely 1 sup:
ported in position to bereadi'ly grasped by Y the hand'of the operato'r for the purpose of turning the sameand thereby increasing or decrcasingthepressu re qf 'the grindiugwheels upon the cutter by causing' vthe wheels to approach orrecede from eafchother. A spring e is interposed vbe t wceifthe nut s and'the outer arm Sso as topermit said arm to yield 'when forced outwardly byanyabnormal pressure upon the disk or diskst n'ding to force them apart,an'd a spring we placed between the hubs of the disksso as to hold them nor mally apart and resist any force tending to cause them to approach each other. By these means, the grinding wheels are held in yielding engagement with the sides of the cutter and the disksare forced apart by spring pressureso as tom'alntain a fixed position in 'respcctto each other and exerta greater orless pressure upon the cu tter,as may be desired,

ter will thus be ground true although it or the wheel maynot be true, as is generally thecase,
and cutter perfectly true, U denotes an electric lamp iwhich may be it-being difficuit to construct or hang the disks of any suitable or preferred construction and reconnected n circuit with the son rce of elec- 1 tric supply to the motor, so that when current is supplied to the motor the lamp will also be supplied. lhe lamp is adj ustably secured with relation to the cutter so sw g/omit the light to be thrown upon the Work in b dl1 manner as to enable the operator to'readily guideand control the movements of the machine, for the purpose of causing the cutter to follow I the contour-oi the pattern or the sinuous lines or marks upon thejcloth;
The connection may be made by any suitable clamping device which will permit a vertical and lateral ad justment ofthe lamp,-but we preferably'em' ploy for'thispurpose a universal or ball-andsocket joint as shown, which may consist of a 'split or divided clamp V provided with concavities on the inner faces of the free ends of the split'parts to receive a knob o r rounded protuberance it, projecting from the lampsocket vas shown; such-bifurcated portion being provided with a binding screw v, by which the parts may be compressed so as to bind the v knob in the socket formed by the'aforesaid -cdncuvities and-hold the lamp in auyde'sired position.
This construction has theadvautage of permitting a'very nice adjustment of the. lamp,so as to prevent casting shadows across the line of movement of the cutter or the marks upon the cloth, and adapts the light tube thrown tothe best advantage to meet varying conditions and requirements in cutting difi'erent kinds of cloth, whereby the operator may cause the knife to follow the any partof a large room, and from table to table, and at the same time prevent entanglement of or interference with the workman by a superfluous length of wire, we provide an antomatic'take-up device, by which thp slack or superfluous lengthof wire is automatically 1 7 taken up-andpaid out in such length as may be desired in moving themachiue from table to" table or overa long table. This device may consist of a cord X secured at one end tothe flexible wires W and extending therefrom over a pulley or pulleys an, :cfl'or other suitable e evated support, and-provided at'its" -tree cud t'i aweighi: us by which the cord rill be t 51 this means an so er--:

upon the shank of the handle being adapted to engage either one of three (more or less) notches in theupper face of the segment, as
inclined either to the right or left of the machine audf-oblique to the axis of the cutter; or in a position parallel with the cutting -'blade.'- V V I In Fig; 6 is shown amodifi'cation of the footplate wherein a dip or concavity a, is formed by a gentle incline from the front edge of the standard to apoint in rear thereof, from which point the slope is gently upward to the surface of the plate. This depression provides a clearance in rearof'the cutter and permits the cloth to dip as the foot-plate moves there'- or acute angles in following the marks upon the cloth. j 1 While we have shown and preferably use a grinding disk for each side of the cutteigit' is obvious that oneof said disks might be' dis pensed with, in which case the spring for holding the disks apart might be interposed between the disk and arm, or a collar on the shaft on which; the disk is mounted, so as to force the disk outward against the opposing pressure of the spring upon the tension rod. The sides of'the disks facingvthe cutter may. be plain or-cored outas shown so as to leave a rounded peripheral projection only to make contact withthe edge of the cutter. The foot plate is also prcferably'mounted on rollers which may be placed at "the four corners thereof so as to prevent friction and facilitate the movement of the machine. A switch of i any suitable construction as shown at X may be employed for turning on and cutting off the current. It is also obvious that while an electric motor is/preferable any suitable motor may be employed in connection with a and sharpening devices such as we have described Hence We do not desire to be lim-'" ited to the exact construction and arrange- K ment of parts shown and described.
