Filed July 2, 19s7,'sei-. No. 669,519 16 Claims. (Cl. 242-62) The invention herein disclosed is amachine for packing pile fabrics. To protect the nap or pile, ithas' been the practice to wind such materials in spirally separated layers by catch-I ing the selvage edges of the material over sharply pointed supporting hooks on the opposite end heads of a rotatably mounted rack or reel.

* United StatesfPatent Q 7 2 clutch levers as they come around into the wire feeding position.

Fig. 5 is a vertical sectional View of one of the end heads as taken on substantially the plane of line 55 of Fig. 1.

Fig. 6 is a broken sectional detail showing the detachable connection of one of the rotatable, supporting hubs with one of the real heads, this view taken on substantially the plane of line 6-6 of Fig. 8.

This is atime consuming operation requiringthe con- 7 i stant attention of a skilled operator and even under the most favorable circumstances, the cloth may be unevenly stretched, torn or become detached fromthe hooks resultingin impairment and injury to the goods.

Objects of the present invention are to avoid and to eliminate these possibilities and to provide a machine in which pile fabrics and the like may be quickly and accurately, positioned and effectively secured without the possibility of injury or comingloos'e as heretofore- These objects have been attained by provision of a rack i or reel having longitudinally aligned spaced supports for the selvage edges and the provision ofmeaus forprojecting binding wires successively through thesesupports' and through the intervening layers of material posi tioned on such supports.

These operations may be accomplished partly by hand and partly automatically or be either wholly automatic or manual as will be seen in the course of the following description.

Other important objects of the invention are to provide a machine of the character indicated of relatively simple,

inexpensive construction not' requiring the services of a of the machines With the upper armsof the reel appearing in section. q I j Fig. 2 is an enlarged broken part sectionaldetail of one of the'arms showing two layers of cloth engaged in the holding notches thereon and pierced by the securing wire associated with thatarm, the full lines indicating A position of the actuating lever in the wire feeding act and the dotted lines indicating the normal rest position of this lever. a

Figs. 18 and 19 are broken detail views of a modified form of holding means for the cloth.

Fig. 20 is a diagrammatic view illustrating a further modification in which the successive layers of the cloth are supported on rods inserted in socketson the arms of the packaging reel.

As particularly shown in Figs. 1 and 5, the reel or rack is madeup of opposite end heads 15 and 16 secured in spaced relation by spacing bars or rods 17 and supported in the machine by projecting stub shafts or hubs 18, removably seated in open journal sockets 19in spaced upright stands or posts 20.

' Fig. 6 shows how these supporting shafts maybe secured in quickly removable relation to the end heads by through screws 21. Quick acting clamps may be used for the same purpose. a

Fig. 6 also shows. how the reels may be held against endwise movement in the supporting stand by spaced collars 22 on the shafts rotatably engaged over opposite sides of the bearings 19.

Each end head is made up in the illustration of a continuous length of strip material bent into a loop of substantially X formation with triangular end portions providing convergently inclined arms 23 connected at the outer more widely spaced ends by straight bar sections 24 and connected across the center by intermediate spaced straight parallel portions 25.

The longitudinal spacing bars or rods '17 and the cen- V tral supporting shafts 18 are shown in Figs. 5, 8 and 9 as secured between these parallel intermediate portions 25 of the reel head forming strips. 1 For additional rigidity and strength, the intermediate in portions of the arm forming strips 23 may be transversely corrugated or bowed as indicated at 26, Fig. l.

The pile fabric indicated generally at 27, Figs. 1, 2, 5, and 8, is guided, supported and positively and uniformly held in accurately positioned, relation by having the selvage edges of the same entered in notches 28, between aligned supporting loops 29 on the inner edges of the generally radially extending arms of the reel heads.

These loops are shown as provided by doubled or folded strips 30, Figs. 1 and 2, welded or otherwise secured over the inner edges of the generally radially extending arms of the reel heads providing spaced, aligned guide passages 31 for the needles or wires 32.

As the edges of the fabric are engaged in opposing notches in the reel heads, the wires which are aligned with those particular notches, are advanced one step to impale these particular edges, the reel being indexed and held at this point for operation of these particular wire feeding clutches.

The indexing mechanism, as shown in, Figs. 1, 4 and 6, comprises annular flanges 33 on the reel shafts 18 having positioning pockets 34 to receive the spring pressed detent plungers 35.

By this mechanism, the reel is brought to a stop and held in position for the binding Wires to be advanced each time a layer of the cloth is engaged in the notches between adjoining supports.

In the machine illustrated, this position is the one shown in Figs. 5 and 8 with the rows of spaced supports 29 and wire 32 substantially horizontal and the cloth 27 substantially vertical.

In this position, wire advancing levers on the reel heads come in to register with levers for actuating the same on the stands or end frames 20 of the machine.

These actuating levers are designated 36, and are shown hingably mounted at 37 on vertical axes on the supporting stands in position for vertically spaced projections 38, 39 thereon to engage clutch levers 40, 41 respectively.

Because of the X-shaped formation of the reel heads, the clutch levers 49 which are diametrically opposite, Fig. 10, are at a lesser distance from the reel centers than the opposite clutch levers 41 so the lugs 38, 39 on actuating levers 36 are positioned at one time to operate levers 40 and the next time to operate levers 41 on the two reel heads.

While power means may be provided for the purpose, the actuating levers 36 are shown as operated in the present disclosure by pull cables 42 extending through guides 43 from the two reel stands to a cross-pin 44, Figs. 5 and 7, sliding in a slotted bracket 45 and actuated by a pivoted link 46 connected with a foot pedal 4-7. This may be a Bowden wire type of flexible connection between the operating pedal and the two clutch actuating levers.

The clutches for feeding the wires and for holding the wires against retractive movement may be of the automatic ball and cone type as shown in Figs. 2. and 3, though it is contemplated that spring pressed pawl clutches may be employed, the latter having the advantage that they may be of open construction and hence, be more readily released if there is occasion to release them from the wires.

The feed clutches are designated 48 and are shown mounted on the ends of clutch levers 4t and 41 faced to advance wires 32 through the spaced selvage supports or holders 29 and the holding clutches are indicated at 49 on stationary brackets 50 faced to prevent reverse movement of the advanced wires. 7

The wire advancing movement of clutch levers 4-3, 41 is adjustably' controlled by set screws 51, Fig. 2.

Springs 52 yieldingly hold the clutch levers 40, 41 in the retracted position shown in Fig. 1 and springs 53 normally hold the actuating levers 36 in the open or inactive position appearing in this view and shown in dotted lines in Fig. 2.

Operation As shown in Figs. 1, 2, 5 and 8, the selvage edges of the pile fabric 27 are introduced in the notches 28 between adjoining spaced supports 29 to form the spiral pattern indicated. This engagement of the cloth folds over successive supports may be a hand operation or be efiected automatically or semi-automatically, as by using guides to direct the cloth into successive notches. The reel may be rotated, a step at a time or continuously by hand or by automatic means.

In the machine here illustrated, however, the reel is indexed by detent 35, Figs. 1 and 4, to stop and hold it each time that'one of the feed clutch levers 40, 41 is in line with lugs 38 or 39 on actuating levers 36. While the reel is thus indexed, the foot pedal is depressed causing Bowden wires 42 to pull the actuating levers 36 from the position shown in Fig. 1 to the full line position shown in Fig. 2, whereupon one pair of the lugs 38 or 39 will engage and operate clutch levers 40 or 41, this engagement alternating in the successive steps of rotary movement as above explained.

With each action of clutch levers 40 or 41, the wires 32 will be advanced as shown in Fig. 2 through one pair of cloth supports 29 into the next adjoining pair of cloth supports and through the layer of material then engaged between said supports.

These wires may be pointed as shown in Figs. 2 and 3 to pierce the selvage without spreading or tearing.

After a reel is fully loaded, the wires may be secured against accidental removal and the reel be removed from the stands by lifting it up out of the bearing sockets 19 after which the supporting shafts 18 may be removed by releasing set screws 21, Fig. 6, or the clamps or other means for temporarily securing these shafts to the reel heads.

The reel is of light, but strong construction with the arms reinforced by the wires extended through the rows of cloth supports.

In the fully automatic form of the machine illustrated in Figs. 12 to 15, the fabric is automatically entered in the notches 28 between the holding fingers 29 by grippers which engage the selvage edges and pull the fabric down and outward into the notches and advance one step laterally into alignment with the next row of notches at the end of one full revolution of the frame.

In these views the grippers are shown as made up each of a fixed jaw 54 and a companion jaw 55 pivoted at 56 and actuated by a leverage extension 57 carrying a pin 58 riding in a parallelogram cam groove 59 designed to open the jaws in the fully retracted position, Fig. 12, and to close them in the projected position and hold them closed while drawing the selvage edges into the notches, Fig. 13.

Inward and outward movement of the gripper jaws is effectedin the illustration by plungers 60 connected by pivot links 61, Fig. 14, with the slides 62 carrying the fixed and relatively movable jaws. These plungers may be the magnetic cores of solenoids 63 but it is contemplated that hydraulic or compresed air cylinders and pistons may be used instead of the solenoid constructions illustrated.

Thegrippers are indexed to lineup the cloth with the spaces between the supporting fingers by means here shown as solenoids 64, operating plungers 65 carrying spring pressed pawls 66 in engagement with ratchets 67 on the slides 68 carrying the base plates 69 on which the gripper solenoids 63 are mounted. In this case,

also hydraulic or compressed air cylinders and pistons may be employed in place of the feed solenoids 64 and this feed mechanism may be controlled by cams or otherwise to bring the grippers and particularly the cloth held by the grippers into register with successive pairs of the holding notches. t

The entire gripper mechanism may be mounted for vertical movement and this mechanism actuated, when the grippers are closed, to pull down successive lengths of the cloth to extend from one pair of the radial arms to the next pair of such arms.

As an alternative, the reel, after the grippershave released hold on the cloth, may be rotated a step at a time to advance the cloth around the reel. This step rotation of the reel may be by hand orby paw and ratchet or other such mechanism. I

Instead of advancing the binding wires through the cloth one layer at a time, the wires may be advanced through'all the layers after such layers have been wound on the reel. 7 n I v I In such case, it may be desirable to temporarily catch the selvage edge on the holding fingers and this may be accomplished by providing those fingers with sharp holding points as indicated at 70 in Figs. 16 and 17. These sharp holding points may be put directly on the holding fingers or on the supporting arms carrying these fingers as will be clear from the views referred to, and they may be located at different portions of these members where most convenient for catching the selvage and temporarily holding it before the wires are inserted.

To prevent the wires catching in the holding fingers, the entrance ends of the fingers may be turned inward to form a. funnel structure 71 for guiding the wires and preventing them from catching in the openings left by the punched out holding points 70.

The selvage edges may be automatically caught and held in the supporting slots or notches by means of pointed spring toggle levers arranged to snap from open to closed'cloth holding position. These spring catches may be constructed to' be actuated by the edges of the cloth being insertedin the notches. a

Figs. 18 and 19 illustrate a form of these spring catches, comprising sharp pointed hook levers 72 pivoted on the arms 'ofthe reel at 73 in position to penetrate or grip the cloth inserted in the notches and adapted to snap into and be held in either the open or closed relation shown in Figs. 18 and 19 by springs 74 acting on the pins or shoulders 75 on the levers. These hook levers-are shown as having angular extensions 76 at the inner ends to be engaged by the cloth entered in the notches to snap them into closed position and as having lugs 77 projecting in the closed position of the spring catches and by which they may be snapped to openposition, if not released or fully opened by withdrawing the cloth from thenotches in unwinding from the reel.

Other modifications come within the intent of the invention, including the provision of rods 78- or stifi wires which are dropped into sockets in the arms of the reel, in back of the cloth as the reel is rotated'to wrap the cloth in spaced layers on the same as indicated in Fig. 20.

For holding some cloth, the binding wire may be in the form of stiff thread, cord or the like, of plastic or other suitable material.

In the wholly automatic-form of the machine, where the. cloth is advanced, engaged with and secured onthe supports and the reel rotated in time with the advancing and securing aotions,.the parts are driven in properly.

synchronized relation by electric motors or other power means. Motors may be employed as well in the semiheads are automatically projected beneath the cloth, these fingers preferablycarrying points which will penetrate to hold the cloth in position while the reel is tuming into position for a succeeding pair of the fingersto be projected into the holding relation.

It will be understood that a throw-away form of reel, .if desired, may be removably set in the reel heads positioned to have the cloth wound thereon and adapted to wholly support the wound layers of cloth after the supporting fingers, of the reel heads are withdrawn on completion of the winding operation. Before removing the throw-away? frame from the machine, binding wires or the like may be passed through the wound material in a manner such as previously described.
