(Cl. -2l8--32) 14 Claims.

This invention has general reference-to beaming apparatus such as used in the textile arts and, more particularly, relates to the species there-oi commonly known as beam warpers; the primary object being to providea novel form of manually-controlled and similarly-operated :dofiing means whereby the beam, when full of yarn, is easily lowered to floor-level for removal, and correspondingly raised when replaced by :an empty beam.

Another object of this invention is to provide a doting-means of the form above indicated including refinements, whereby the beam is adjustably mounted and accurately positioned in the beam warper with positive assurance of maintainingits correct position during the warning operation.

.A further object is to provide a novelme'ans whereby the beam is detachably .journal'ed intermediate the spaced ends of a rotativeand a nonrotative shaft means with positive assurance that all of such parts are held indirect coaxial align ment.

Astill further object of this invention is to provide a cloning-means of the type above mentioned including means whereby the beam :issecurely restrained against vertical or other displacement when in active Warping position, or when lowered to d'ofiing location.

With the above" stated fundamental objects in view and others with ancillary advantages which will be later on referred to or become apparent; to those-skilled in the art, upon an understanding of the construction, combination and-arrangementoi means hereinafter disclosed; but it will also be appreciated said means are susceptible of modification or change from the specific embodiment, typically illustrated by the accompanying drawings, and more particularly defined in the concluding claim.

Fig. 2 is a side elevation of the same as viewed looking from the right toward the left-hand. of Fig. 1.

Fig. 3 is a plan section taken approximately .as indicated by the angled-arrows III-II-Iin Fig. '1, with other parts broken out and also in section for a clearer understanding of important details. Fig. 4 is'a vertical section through one of the spaced side columns, hereinafter fully explained, with the beam and associated driving-shaft in the lower, or dofling, position; and,

Fig. 5., ii's'a verticalsection, to the preoedingbnt showingthe beam and driving-shaft elevated, or in the active warping location.

In describing the form of this invention exemplified by thezdrawing-s" herewith, specific terms will' beemployed for the sake of clarity, but it is to :be understood the scope of said .invention is not therebyxlimited; each such term being intended to embrace all reasonable equivalents which-"perform the same function for an analagous purpose.

Referring more in detail to the drawings, the referencecharacter B comprehensively designates a *tricot beam-Warner embodying the improvements of invention; said 'warper including a reed 1, through which the warps of vvarns-not indicated-are drawn from the tensioning means a. ioripassageover the cross-over roll- 9, and down from thetatter to the beam Hl nponwhich they are-collected and wound, in accordance with known practice. The tricot beam-warper 6 comprises 1 spaced columns H preferably, although not-essentially, of. substantially channel formation,=and:one"of winch embodies, or has attached thereto, a r-earwardly projecting housing ['2 near the lower :part thereof, for a purpose later on explained-while it is to be particularly observed that the torward or frontal edges of the column side walls are appropriately enlarged at It and shaped to define outwardly-directed bevel-edged lateral flanges 15, which afiord directly vertical guidance for individually-associated driving head right-and-left hand assembly-carriers or slides 45,. H respectively. Each slide l6, i1 is provided with inner and outer runners or guides 18, I9 conveniently, although not essentially, attached thereto by suitable securing means 1 :20; whereas rect'ang-ularlyestepped parts 2! of the outer guides to are :fitted with triangular-section inserts 22 for-sliding coaction with the bevel-edged flanges 45, above referred to, vand such inserts are arranged to be rigidly clamped against the flanges 1-5 by. aid of hand-screws 23 in an obvious manner and for a purpose later on hereinafter explained; it being understood that the inserts 22 are restrained againstlengthwise displacement by fillet abutments 24 in the guides [9, see Fig. 2, to best advantage. Preferably the respective spaced columns -l l are braced at their front open portions by appropriate upper and lower cross-webs 25, 26, respectively.

'Referringnow first to the right-hand slide l6, for example only, which carries-or supports a driving-head for the improved beaming apparatus 8, such sl-icle being preferablyof rectangular contour, as best appreciated from Fig. l, with a correspondingly shaped aperture 21 therethrough; while said slide l6 affords support for a drop-bracket or hanger 28, of channel formation, at its rear as well as spaced bearings 29 at the front thereof. There bearings 29 are conveniently attached in the desired position by securing means 30 and jointly afford rotary support for a drive-shaft 3| and, to the inner end whereof is applied as by key means 32, a movable driving-chuck 33. This driving-chuck 33 is under control of a manually-operable shifter 34, see Fig. 1, which is fulcrumed at 35 to a suitable bracket 36, attached to or forming a part of the slide l6, whereas said chuck is preferably of the cupped type; that is to say it includes a hollow section 31 provided with interior teeth 38,for cooperative engagement with a corresponding gear 39 made fast to the confronting end-of the beam spindle 40, in an obvious manner.

The beam-spindle 40 is preferably tubular for reception, at its end remote from the gear 39, of the reduced end 4| of the non-rotative tailstockshaft 42, which is suitably supported in special bearings 43, 44 conveniently made fast to the slide ll of the left-hand column H by attaching means 45, for instance. Particular attention is directed, at this juncture to the fact that the shaft 42 is enlarged or shouldered at 46 adjoining the reduced end 4|, for a reason later on herein explained. It is also to be noted that the bearing 43 embodies vertically spaced lugs 41 between which are fulcrumed, by a pivot element 48, a hand-lever 49 having a fragmentary gear portion 50, at its inner end, for meshing engagement with a toothed rack or key inset in the tailstock-shaft 42, whereby the latter is restrained against rotation but is capable of predetermined longitudinal movement in either direction as later on again referred to; stops 52, 53 on the spaced lugs 41 restrict such movements by coaction with a projection 54, see Fig. 1, on the hand-lever 49.

Turning now to the bearing 44-, the same somewhat conforms to the bearing 43, just above described, in that it is of similar size and general contour while being secured to the tailstock slide IT, by like attaching means 45. On the other hand the bearing 44 is provided with a hollow projection 55 in which is fulcrumed, by a; pivot element 56, a hand-lever 51 embodying a cam-portion 58 excentrically related to said pivot element and whereby the tailstock-shaft 42 is locked in the active position, again referred to herein, while 59 indicates a movement limiting stop for a purpose later on explained. 7

A suitable housing or cover 60 for the rectangular aperture 21 in the carrier-slide l6, intermediate the spaced bearings 29, is conveniently attached to the carrier-slide l5 by screw-studs 6|.

Surmounting and rigidly-connecting the columns II is an appropriate frame member 62 affording rigid support not only for the bearings 63, of the cross-over roll 9, but also gear-housings 64 through which are journaled a transversedoffing-control shaft 65; such shaft having keyed to each end thereof a hand-wheel 66 whereby said shaft 65 may be rotated in either'direction, as hereafter further amplified. Also keyed on the shaft 65 within the respective housings 64 is a sprocket-gear 61; and on a stub-shaft 68 secured across each said housing 64 is a spacedly related and vertically-adjustable idler sprocket gear 69; while over bothof the associated gears 61, 69 there is trained a chain having one end attached medially to the respectively associated tional or other beam Ii] is rotatable to collect or wind the yarn or yarnsnot indicatedthereon, the same preferably comprises a multi-groove drive-pulley l3 keyed at IL-Fig. 3on the driveshaft 3|, a pair of spaced similarly-grooved idlerpulleys l5, 16 on stub-shafts TI across the hanger 28 of the right-hand column II, for example; as well as an upper correspondingly-grooved vertically-adjustable idler-pulley or sheave 18 on a transverse shaft 19 across said column, and a similar lower driver-pulley B5 on a transverse counter-shaft 8|, also in such column. These pulleys 13, I5, 16, 18 and preferably have trained thereabout endless V-belts 82; the sinuous course of which may be briefly as follows: outwardly and downward about the drive-pulley 13 carried by the bearings 29 then upwardly and over the idler-pulley 16, from which it goes-down under the lower driver-pulley 80 on the countershaft 8| across the column ll, thence up and over the vertically-adjustable idler-pulley or sheave 18 on the shaft 19; and from the latter down to and partially about the idler-pulley 15 to the first mentioned driver-pulley 13, as clearly understandable from the associated arrows in Fig. 5, whereby the beam ll] is rotated to wind-up yarn or yarns thereon.

Power is appropriately, although not essentially, imparted to the transverse lower countershaft 8| through the medium of multi-groove pulley 83 fast on said shaft, with associated V-belting 84 also trained about a correspondingly grooved driver 85 secured on the power-shaft 86 of an electric motor 81; said driver 85 and V-belting 84 being enclosed by the housing or guard |2 at the lower back portion of the column I l, which is provided with an opening 88 for free passage of such belting, in an obvious manner. 89, Fig. 1, indicates a conventional presser roll for coaction with beam L0, and 90 in said figure designates positioning guide rails for entry by the beam end flanges 9| to facilitate insertion and removal of the beam ID, in the warper 6, as hereinafter set forth.

Before proceeding to explain the functioning of the various instrumentalities and structural devices described, it is to be noted that the warper 6 is operative regardless of the elevation of the beam ID, by simply starting the motor 81, and vice versa. Assuming now, that the beam Ill be in the active position of Fig. 5, with the handscrews 23 tightened-up it will be readily understood that when the motor 85 is activated said beam can be rotated, through the belt drives 82 and 84, until it has collected the desired amount of arn thereon ready for dofilng whereupon said motor is stopped. The operator now simply releases or retracts the hand-screws 23 and turns the most convenient hand-wheel 66 counterclockwise, whereb the associated sprockets 51 are correspondingly rotated under conjoint and uniform movement'of the chains 10 with descent of the respective headstock and tailstock carrierslides l 6,'=l I ,-and the opposingipull of theeounterhalancirrgwveights Jl whereby the. loaded beam in! is and smoothly lowered until alts send 'l-lmgessml in ithe Y guide-mails amat floorlevel.

From theforegoing disclosure the meritsand efiiciency of the apparatus disclosed hereinbeiore willbe (clearly understood but it is-desiredin conclusion to stress certain features of prime importance. Firstly by turning either of the handwheelsifit in 'the proper'direction the operator causes ,the associated sprocket wheels 61 .to correspondingly turn and thereby permit the headstock and tailstook carrier slides l6, l1, that are attached to the chains 1.5,.teloe lowered arraised in-mn'ison, while the hand-screws 23 securely clamp said slides elevated in position for the active or beaming operation, as well as when lowered for the purpose of dofiing. Furthermore by seating the housings 64 for the sprockets 6T, 59 on top of the hollow columns H, and since the sprockets 61 are keyed on the doling controlshaft 65, the carrier-slides 16, I1, with the associated parts, will always be kept in perfect alignment both when said slides are moved up or down.

Finally, while there has been disclosed one prac'tical 'embodimentiof this invention, it is to lee understoed that changes -and wariations will #be-appa rerit to those:sktlledxinithe art in adapting novel fldofllng mechanism 1 differing types and iorms of ibeaming apparatus; and wall such ohangesandwariations-are hereby contemplated asmayk'be irremdable within the termszand zscope of the :fiollowing ecla'ims.
