' Appleman nea nach e, 190s.

To all whom it may cori/carri@A a l l Be it known that I, MALGOLM`MOKELLAB, a subject of the King of Great Britain, residing at Nesbitt, county of Brandon, Province of Manitoba, Canada, have inventedcertain new and useful Improvements in ClothMeas'- 1 `uring Machines; and I do hereby declare that the followingis a full, clear, and exact description of the invention, such aswilllenable g others skilled in the art to which it appertains kto make and use the same.

My invention relates to machines for measi uringfabric, and it is expected to be espe-l cially useful in Wholesale houses, factories', dro., which must supplyv cloth to customers.'

, The invention consists in the construction and combination of `parts to'be more fully described hereinafter and definitely set forth in the claims. 'l y In the drawings, which fully illustrate my inventiom Figure 1 representsthe device ini side elevation. Fig. 2 represents the machine f in plan, the web of cloth represented being; shown as broken away to more c1ea'rly;dis= close the construction. of the 4mechanism Fig. 3 is a transverse vertical section taken g substantially on the line- 3,3 of Fig. 1. Fig. l 4 represents in perspective a portion of thei table included inthe'device'and showing a;

Asupport for the 4cloth-roll.V Fig. 5 is a verti cal section taken substantially upon the line l-5 5 of Fig. 2, but upon a somewhat enlarged scale. Fig. 6 represents in perspective a portion of the mechanism for guiding the web of, cloth as it passes. Fig. 7 represents also in' perspective another portion of the mechan-t ism for guiding thewebof cloth. This view' represents the parts in an inverted position.k

Fig. 8 represents kin A'perspective one of the' gudgeons which I 'us'ein' connection with the. apparatus. I

Throughout the drawingsand specification the same numerals' ofrefei'en'ce denote like parts.v Referring more particularly tothe parts, 15 represents a substantial table supported upon suitable llegslt, as indicated. Preferably at. substantially its vvmiddle 'point `rthis table is provided with a pair of oppositely-disposed standardsV 17, which constitute supports for a measuring-drum 18, mounted between the vsame'. This drum may be provided with a SerialNo.146,S15. (No model.)

' f suitable axle or' arbor 19, the extremities of which areheld in .therinclined slots 20, formed infche side of the standards 17 in the manner shown. At their upper portions the standards17 areprovided with vertically-disposed ,slots orvopenings 21, -in which'are guided blocks'22, whichjblocks constitute bearings 'for thereducedextreinities of a presser-roller 23, .which is, disposed between the supports, as indicated. j These blocks 22 are provided with'vertically'- extending stems 24, which pass through the'upper wall of the slots 21, and around these'fstems there are coiled helical' springs 25, which'- thrust. downwardly against the blocks 22, so that the presserroller23 iscoustrained in a resilient manner lagainst the upper face of the aforesaid measuring-drum 1S.

At its opposite ends the table 1 5 is provided with transverse guiding-grooves 26, A which constitute shears upon which are mounted pillow-blocks or pedestals 27 and 30, respectively,which have' openings 2 8, conforming substantially tothe outline of the 'table ends, as shown." rIt'sh'o'uld be understood that thesepillow-blocks are adapted to `slide laterally of thetable upon the' shears '26, and they' may be clamped in anypo'sition 'desired bymeans of the thumb-screws 29.

It should be understoodt'hat the pairs of pillow blocks 27 Aand '30 support' between them, respectively, the rolls 31'32 of the material which is being measured, so that the Nweb 33 of the material lying between the two rollers passes over the vupper surface of the measuring-drum, passing between it and the aforesaidpresserro'ller 23 in the manner indicated. The fabric represented as being measured is supposed to be ordinary cloth, and it will be'remembered that these rolls are usually formed by `winding the material around a board 39, These boards 39 are supported between gudgeons'f, which comprise diverging jaws 35, adapted to receive the Vends of the boards, as shown. They comprise also necks or shanks 36, which constitute journals mounted in the pillowblocks, so that the rolls are rotatably supported, as will be readily understood.,V To' this kend the Ypillow- blocks 27 and 30 are providedwith openings 37, in whichv are Vmounted blocks 38 39, which 1ie,respective1y, below and above the journals 36 and constitute bearings therefor. The upper blocks 39 are adapted-to be forced1 downwardly against the journals by means of clampingscrews 40, carried in sleeves 10, whereby a frictional resistance may be offered to the rotation softhierolls.,y It should be understood that the material is to pass in the direction of the arrow, and forv the purpose of winding itv upon-the Vvroll 32 one of the gudgeons of this roll is provided with a square extremity 41, to which is attached a suitable crank Y42. 'As' the -web passes from the measuring-drum 18 it r11-ns under a horizontal guide-roller 43, suitably mounted between the supports 44, bolted to the table in the manner indicated. At the' opposite side of the drum the webl passes under a tension-roller 45, the arbor 46 of which has its extremities mounted in a vertically-f disposed slot 47, formed in the standards 48, which are secured tothe table 15 in the. manner indicated. It should be understood L that this tension roller constitutes also ai guide-roller for the web, and it should be stated that by reason of the fact that it is free to move vertically its weight operates to maintain the web in a taut condition as it passes over the measuring drum 18, and in this manner inaccuracies of measuring will be averted. This'tension-roller 45 has been shown in its extreme elevated position. As the web 33 passes from thehorizontal guide-roller 43 it passes between the vertical guide-rollers 49, of which there are two 'dis-l posed oppositely, as indicated. These rollers 49 are provided with bores 50, which enables` them to be loosely mounted upon vertically-I disposed studs 51. These studs are mounted, respectively, in plates 52 53, which are sub-E stantially of the construction shown in Figs..I 6 and 7. It should appear that the plate 52 comprises a boss or projection 54 on its upper side, while the plate 53 comprises a boss? 55 upon its lower side. -It should be observed. that the plates are provided with elongated openings or slots 56 57 in lthe manner shown. It should be understood that these slots are5 of substantially the same width and are adapted to constitute guides, respectively, forthe; projections 55 and 54 when the two plates arej properly applied to each other, as will be readily understood and as indicated in the figure.; The studs 51 aforesaid may beprovided with@ enlarged heads 58 at their lower extremities,l which are countersunk, as indicated, into the lower faces of the plates 52 and 53. A clamp-li ing-bolt 59 passes through'the aliningeslots 56 and 57 and is adapted to clamp the platesf together and hold them firmly upon the table,l a suitable wing-nut 60'beingprovided for this purpose. y The measuring-drum 18y I ,preferito make? just one yard in circumference. One of its; end faces is provided with apin' 61, which describes a circle about the axis ofthe drum as the same rotates. At every revolution this= pin comes into contact with the edge of a1 counter-wheel 62, which itiadvances through one -unit or graduation--toindicaterthelamount of cloth measured. This counter-wheel may be loosely mounted upon a fixed stud 63,which stud carries rigidly a pointer 64, which indicates-whereathefreadingis to be taken.

It should be observedthat the length of the rollers 43 and 45 is substantially the same as athatfof thevmeasuring-drum 18, and it should be understood from the construction of the apparatus described that the pillow- :desireddistance apart, so that cloth of various widths may be readily measured. It should also appear that theconstruction of the parts in connection with thevertical guide-rollers'49 enables asimilar adjustment in width to' be eected withVv respect to them.

While I lha'vevshownl in the accompanying drawings the preferred form of my invention, it will be understood thatI do not limit myself to thej precise formv shown, forv` many of the .details maybe changed .in form or position without aecting the operativeness .er utility of'my invention, andI therefore `reserve the right tov make all such modifications as are included within the 'scope'of' the following claimsorof mechanical equivalents to the structures set forth.

Having thus described my invention, what I claim as new, and desireto secure by' Letters Patent, is-
