(ci. a- 1.1)

14 Claims. 1

The invention relates to an apparatus for mak-v ing a pile fabric or product constituted of a ilexible backing upon which is deposited, in substantially upright position, any character of pile forming material, and permanently embedded into an adhesive composition coating the ilexible backing.

The invention, more particularly, conslsts in the provision of an apparatus for making such pile products on a commercial scale, and with a substantially continuous operation of such apparatus, whereby the yield of pile fabric from the apparatus is sulicientlyA large and the pile product is produced at a suillciently rapid pace to make the utilization of such apparatus on a. commercial basis favorably competitive with the ordinary commercial embodiments of'other types of pile fabric producing apparatus.

Reference is made to my copending application Serial No. 439,579, filed April 18th, 1942, now Patent No. v2,358,368, dated September 19, 1944 in which I disclose a method and Apparatus for making pile fabrics, and upon the apparatus of which application the present apparatus isl an improvement.

In such copending application, I have disclosed an apparatus for producing a pile material in which apparatus, however, there is .incorporated a single and individual mechanism for applying a plurality of fiber elements to constitute the pile to the backing at the pile forming station.

In the-present application,on the other hand, I shall describe, in conjunction with the accompanying drawings, a commercial embodiment of my apparatus which is so constructed as to operate on a cyclic basis, utilizing a single pile forming station but a plurality of sets of mechanisms for bringing the pile forming material to such station, whereby the capacity and speed of the apparatus is greatly increased and a sub` stantially continuous operation of pile forming In addition to the provision of mechanism for the cyclic operation of particular elements of my apparatus, there are incorporated in the new and commercial embodiment of my invention, as hereinafter disclosed, a number of improvements, both in the mechanism and controlling elementsV thereof and in theA actual structural design of various components of the apparatus to make the assembly smooth in operation and to have a substantially continuous yield of pile product from the substantially continuously operating machine elements.

The primary and distinguishing feature of an apparatus for forming pile fabric, as herein disclosed, is the use of what will be hereinafter termed a drum," which comprises a rotating element from which extend radially a plurality of pile element grasping mechanisms Such mechanisms, upon the step-by-step rotation of the drum, grasp the leading edge of a line of fabric elements severed from their source of supply and then transfer the severed predetermined length of ber'elements to a pile forming station and thereafter cause the embedding of such pile elements into lthe cementitious coating spread uniformly upon a flexible backing.

The utilization of such rotating drum involves also the provision of certain novel Amechanism for its control and movement and the present application discloses such control mechanism, for instance, a locking lever and bumper hook for such drum.

In my novel commercial embodiment of apparatus for forming pile fabrics there is incorporated also a somewhat different type of jawclosing and jaw-opening device from that disclosed in my prior copending application, as well as a modified form of knife holder and knife operating mechanism.

Various other improvements in the apparatus are illustrated in the accompanying drawings and will be described hereinafter in conjunction with the exposition of the specic pile forming apparatus shown in such drawings.

In the following description of the particular commercial embodiment of my apparatus illustrated in the accompanying drawings, it will not be necessary to describe in detail those elements of the apparatus which are substantially identical or very slightly different from the specific embodiment of the similar, but single operative, embodiment of the apparatus shown and described in my said copending application. Wherever, however, the description of such mechanism, even though illustrated and described in said copending-' application, is deemed necessary for an understanding of the operation of my present commercial embodiment of the apparatus, such parts and'mechanism will be again, however brieiiy, referred to.

In the accompanying drawings, Fig. 1 is a side elevation of the actual commercial embodiment of an apparatus, for forming a pile fabric, constructed in accordancewith my .present invention; Fig. 2 is an end elevation of such apparatus.

the view being broken centrally of the machine` but showing all essential parts thereof in full; Fig. 3 is a side elevation on a somewhat enlarged scale with a portion of the frame of the appa ratus removed; Fig. 4 is a. side elevation of the drum by the utilization of which the continuous "cyclic operation of my apparatus is obtained, showing also the mechanism for opening the jaws grasping the pile forming elements; Fig. 5 is an enlarged detail of the mechanism at the lower right hand portion of Fig. 4, showing the pile grasping jaws in their open position; Fig. 6 is an elevation of part of the mechanism shown in Fig. 5; Fig. '7 is an enlarged end Velevation of the pile grasping jaw closing mechanism; Fig. 8 is a side elevation of the jaw closing mechanism of Fig. '1; Fig. 9 is a section on the line 9-9 of Fig.

3; Fig. 10 is an enlarged detail of the drum a'dvancing pawl; Fig. l1 is an enlarged detail of the drum locking pawl; and Fig. 12 is an enlarged detail of the mechanism for controlling the cutting action of the knife and the raising thereof from its pile element cutting position (the portion of the mechanism shown at the upper left hand part of Fig. 3).

Referring more particularly to the drawings, in which similar reference characters identify similar parts in the several views, the general relation and character of the various elements constituting my novel apparatus are best illustrated in the assembly or slide elevational view of Fig. 1, and the end elevational view of Fig. 2. In such figures, I3 is the main frame upon which the machine elements are supported, the main driving element, an electric motor I4, being suitably disposed upon the frame below the pile forming mechanism, the main driving pulley I5 and belt I5 being shown in Fig. 1.

The main driving pulley I5 drives, by its belt I6, a wheel I1, upon the shaft I8 of which is secured, by an eccentric wheel I9, one end of a link or arm 28, the other end of the link or arm being secured in a slot 2l of a rocker arm 22 pivoted at 23 and carrying at its outer end a pawl 24. The movement of such rocker arm 22 causes the periodic rotation or advancement of the wooden roller 25 by which the finished pile product is drawn from the apparatus, the roller being provided with conventional carding wire teeth 26. The roller 25 constitutes a carding wheel which advances the backing strip through the apparatus from which carding wheel the nished product is then led to the vulcanizing oven and pertinent parts not herein further described as they are shown and described in my aforesaid copending application.

Coming now to the description of the pile forming mechanism, such mechanism is constituted of a drum generally designated as 21 which, in the illustrated embodiment of my invention comprises eight pile gripping jaw mechanisms radially disposed within and extending from said drum.

The rotation or step-by-step advancement of the drum 21 is accomplished as follows:

Uponthe shaft I8 and adjacent the pulley I1 is a smaller pulley 28 from which extends a sprocket chain 29 rotating a sprocket wheel 30 mounted upon a shaft 3|. From the shaft 3l extends an arm 32 to which is connected the end of `a link 33. The upper end `of such link 33 is in turn connected to an arm 34 mounted on the main shaft 35 of the drum 21. As the link 33 moves vertically, it causes the rotation, through the intermediary of arm 34 extending from the shaft 35, of the drum 21. The extent of the rotary movement of such drum is governed by a cam 36 which has four notches therein. The

pawl 31, mounted on arm 34 controlled by a spring 38, is adapted to enter one of the four notches in the cam. Upon the shaft 35 is mounted a large gear 39 meshing with a pinion 48, causing a change in the direction of the rotation in the drum from that of the cam and large gear 39. On the same shaft that carries the pinion 40 is a pinion 4I meshing in turn with an internal gear 42. The ratio of the

gears

39, 40 is such as tovcause the rotation of the drum 1A; of a revolution, each time the cam 36 is rotated 1/4 its revolution.

On the shaft 35 of the drum 21, is a large disc 43 having eight notches 44 therein by which is adapted to be caught a bumper hook 45 hereinafter described in greater detail. The disc 43 is likewise provided with eight locking recesses 46 in which a locking lever 41, also described in greater detail hereinafter, is adapted to be seated.

On the shaft 35 is a xed cam 48 having a raceway 49 in which rides rollers 50.

Radially disposed within the rotating disc 43 are slots 5 I through which extend arms 52 which carry at their farther ends the jaw mechanism generally designated as 53.

Turning now to a description of the mechanism for controlling the rotational movement of the drum 21, the bumper hook 45 is shown in enlarged detaily in Fig. 10. Such bumper hook is pivoted upon the shaft 54 riding in a block 55 controlled by a compression spring 56. The rocking of the bumper hook 45 about the shaft 54 is accomplished by means of an arm 51 pivoted upon shaft 58 and carrying at its free end a roller 59. The shaft 58 is connected to the rest of the structure in order to properly time the release of thel hook 45 or of the hook 41 by means of the chain extending over the various sprockets illustrated at the upper righthand portion of Fig. 3, including the sprocket of shaft 58. Such shaft is therefore periodically rotated by said chain. Each time the drum 21 completes its 1/8 revolution the bumper hook 45 engages, by its nose 60 within the notch 44 of the disc 43. The bumper hook is effective to position the drum 21 at the exact necessary degree of its rotation, so as to bring the jaw mechanism 53 to the pile severing station and to enable such jaw mechanism to grasp the line of tufts severed from the supply of pile material at the severing station.

The disc locking lever 41 pivoted upon the shaft 54 is controlled in similar manner by the link 51 and roller 59. The locking lever 41 has its nose 6I formed to enter the locking slots or recesses 43 thereby effecting the positive locking of the disc 43, and therefore of the drum 21, in

the exact position of such drum required for the proper positioning of the jaw mechanism 53 at the pile severing station.

The fixed cam 48 is effective -to cause the radial movement of the arms 52 along the slots 5I. As the disc 43 rotates, the rollers 5I) for each of the jaw mechanisms 53 travel in the raceway 49. The raceway 49 is so designed as to cause the radial outward movement, to its remotest position, of each jaw mechanism at the exact moment when such jaw mechanism is opposite the pile severing station. Such disc 43 continues to rotate in the direction of the arrow in Fig. 3, the movement of the roller 50 of each jaw mechanism in the raceway 49 causing the movement radially of the jaw mechanism at the end of each arm `52 until at the bottommost position of each jaw medhanism, i. e., at the pile depositing station after deposit of the pile, the roller travels upwardly in the raceway 49 to a sufficient extent to bring the jawmechanism completely out of its position adjacent the backing at the pile depositing station.

The jaw opening device is illustrated in enlarged detail in Fig. 5 and in association with the is rotated by a gear and chain mechanism shown generally at the upper right hand portion of Fig.

3, which need not be described herein in any great detail, as the various driving mechanisms for the various elements of my apparatus are shown in the accompanying drawings by way of illustration rather than by way of limitation.

As the jaw mechanism 53 reaches the pile depositing station immediately above the backing strip 69 fed through the apparatus as hereinafter described, and has deposited the line of tufts previously grasped at the severing station and brought to the pile forming station, the jaw opening device operates to open the jaws and release the pile forming elements which have been embedded in the cementitious coating of the backing strip 69. The opening of the jaws is accomplished as follows: As the shaft 68 is rotated,` the roller 88, hitting contact shoe 65, of the lever 62, causes the nose 64 to abut the pin 19 of the jaw trigger disc the upward movement of which causes the jaws to open by pushing one of the jaws sidewise.

The jaw closing device is illustratedin Figs. '7 and 8, and comprises a trigger disc 10 having a notch 1| in which rides a pin 12 `controlling the closing of the jaws.

' As shown in Figs. '7 and 8, the arm 13 which is attached to the knife holder 99 by screws 200, carries at its lower free end a roller or other` detent mechanism 14 which upon the movement downwardly of the arm 13 abuts the roller 15 at the end of an arm 16 of a fulcrumed lever and causing the other arm 11 of such fulcrumed lever to abut, by its tongue 18 a roller 19 on the trigger disc 10. The pin 12 travels in the notch 1| which is provided for the purpose of controlling the time of closing of the jaws therefor by first giving free play to the closing mechanism and as the disc 10 rotates the impact of the pin 12 against the lower side of the notch 1| causes the jaw closing mechanism to operate instantaneously.

The backing strip 69, which is to constitute the backing for the pile fabric produced by my apparatus, is supplied from a roll 80 of such material and passes through the apparatus as shown in dot and dash lines in Fig. 1. The backing strip is first brought to a point of deposit of a uniform coating of cementitious material on the upper surface thereof in any conventional manner, for instance, by a device such as is disclosed and described in my copending application. The backing strip is then brought across the apparatus to the pile depositing station where, after being brought momentarily to rest upon a table surface 8| at the exact point of deposit of pile forming elements thereof, it is given an abrupt downward turn and then passes over the carding wheel 25.

The pile forming material generally designated as 82 passes through the apparatus as shown in the dot and dash lines at the top of Fig. 1. The

feeding of such pile forming material is accomplished as follows:

From the shaft 8, by the train of pulleys and V-belts shown in detail at the bottom of Fig. 1, which in turn rotate a. gear train vmechanism 83, the yarn or other pile forming material 82 passes over the pulley 84 and then downwardly under pulley 85, upwardly over pulley 86, and then down to pulley 81; thence transversely of the apparatus through the reed 88 to the pile severing station; The pile severing station comprises a table surface 89 upon which the yarn or pile supply rests and is grasped by the downwardmovement of an L shaped arm 90 which moves slightly forward with the pile forming material and when the leading edge of the pile elements have been severed, moves slightly upwardly land backwardly. This movement .of the Lshaped arm 90 is controlled by cam 9| and vertical lever 92 which carries at its lower end roller 93, rotating along the surface of cam 9|.

Cam 9| controls the upward movement of the L-shaped arm 90. The eccentric |00 and its link |0|, connected to the lever |02, (shown in dotted lines in Fig. 3) returns the L-shaped arm 90 to its laterally outward position. As cam 9i rotates, its low-dwell surface causes a downward movement of the arm 92, thereby permitting the L-shaped arm 90 to grasp the pile forming elements. After such grasping of the pile forming elements by the L-shaped arm 90, the eccentric |00 and its link |0| move the lever |02 forwardly, the L-shaped arm 90 and table 89 moving forward a, corresponding distance.

The slight axial movement of the pile grasping mechanisms outwardly at the pile forming y station to deposit the pile upon the backing is accomplished as follows: As will be seen in Figs.

' clearly shown in Fig. 5. On the other end of the short shaft |04 is a finger |09. As the drum 21 rotates, the arm 52, when it reaches the point of deposit of the pile elements upon the backing, ss started by such linger |09. As the cam |06 .rotates, the second or larger radius face thereof, |01, causes the finger |09 to depress the arm 52. After the deposit of the pile elements is made, the jaw opens and the arm 52 is withdrawn.

The pile severing mechanism comprises a shearing plate 94 anda knife 95 verticallyv movable by the long link 98, shown in Fig. 3, in its position of actual severing by the knife of a line of tuftsv from the supply of pile forming material. As the knife 95 has severed a line of tufts from the supply of pile forming material, such line of tufts is grasped by jaw mechanism 53 brought to its exact pilegrasping position by the drum 21 and the jaws of the jaw mechanism 53 are closed. The rotation of the

drum

21, 1/8 itsv revolution carries the now closed jaws a ditsance one-half circumferentially of the drum between the severing station and the pile depositing station. It will be understood, of course, that as the jaw mechanism 53, which has just grasped a line of tufts. is moving down to a position 1/8 of the total revolution of the drum 21, another jaw mechanism 53 has just reached the pile depositing station and is depositing the line of tufts grasped by it into the cementitious coating of the backing material,
