fl/l/ A A ZNEX 3,004,300 FEED ROLLER ARRANGEMENT IN A (ZOMBWG MACHINE Werner Naegeli and Hansnlrich Eichenberger, Winterthur, Switzerland, assignors to 30h. Jacob Rieter & Co. Ltd, Winterthnr, Switzerland, a corporation of Switzerland Filed May 28, 1958, Ser. No. 738,539 Claims priority, application Switzerland June 1, 1957 9 Claims. (Cl. 19-116) The present invention relates to a feed roller arrangement, more particularly to a feed roller drive for combing machines having a swinging nipper mechanism.
In conventional drive mechanisms the feed roller is actuated by means of a ratchet wheel mounted on the feed roller which wheel is driven by a pawl placed in a separate casing. The latter includes 'a downwardly extending lever carrying a pin which enters a recess in an abutment mounted on the machine frame, upon the forward and rearward swing of the nippers. When the nippers swing to the rear the aforesaid pin slowly glides upwards in the stationary recess and turns the casing so that the ratchet wheel is advanced by the pawl which swings with the casing.
, Another conventional arrangement includes a separate casing which rests on the feed roller axis and in which a pawl actuates a ratchet wheel. In this case the casing is provided with a lever which is connected by means of an elbow lever with a shaft supported by the machine frame so that the lever and the casing swing upon the reciprocating movement of the nippers.
The actuation of the feed roller by the movement of the nippers relatively to a stationary part requires a complicated drive mechanism which has the additional disadvantage of making it difficult to remove the feed roller.
The object of the present invention resides in the provision of a drive for the feed roller of a combing machine which avoids the aforedescribed disadvantages of conventional drives by using the relative motion of the top nipper and of the bottom nipper for actuating the feed roller, i.e., by using the relative movement of elements which are inherently close to the feed roller so that all levers and the like, which are needed in the conventional mechanisms, can be omitted.
In the system according to the invention the entire drive mechanism is located between the lateral cheeks or arms of the top nipper and of the bottom nipper. The teeth of a segment held in engagement by spring pressure with an arm of the top nipper mesh with a gear which is freely rotatable on the feed roller. A pawl connected with the aforesaid gear engages a ratchet wheel which is fast on the feed roller. 7
The segment is provided with an angular protuberance extending laterally beyond the support arm of the top nipper which protuberance affords actuation of the feed roller against the spring pressure when the machine is' standing still.
' The novel features which are considered characteristic of the invention are set forth with particularity in the appended claims. The invention itself, however, and additional objects and advantages thereof will best be understood from the following description of embodiments thereof when read in connection with the accompanying drawing in which:
FIG. 1 is a part sectional plan view of a feed roller 3,004,300 Patented Oct. 17, 1961 FIG. 2 is a cross section of the combing machine, the
section being made along the longitudinal axis of the arm supporting the top nipper.
FIG. 3 is an exploded perspective View of a modification of a detail of the feed roller drive according to the invention.
Referring more particularly to the drawing, numeral 4 designates a stationary support shaft swingably supporting an arm 5 to the free end of which the forward end of a lateral check or support arm 2 (1) of a bottom nipper 3 is pivoted. For oscillating the bottom nipper 3 a bracket having a rearward extension 8 is pivoted to the free end of a crank 9 which is fast on an oscillating drive shaft 10, A top nipper 13 is provided with lateralthe upper nipper adjacent to the cheek 2 of the bottom 7 nipper, the arm 12 being removed in FIG. 1. The pin 15 rotatably supports a hub 60 of a segment 61 adjacent to the carrier 47 of the top comb. The hub 60 is located between the carrier 47 and the portion Z of the pin 15. The segment 61 has a circular periphery coaxially surrounding somewhat more than half of the circumference of the portion Z of the pin 15. This circular periphery is provided with teeth 62 which are in mesh with a gear 63. The latter is freely rotatable on a feed roller 23 and is provided on the outside with a flange 64, the inside of the gear 63 facing the center of the feed roller. The latter is provided with a boss 65 on which a ratchet wheel 66 is made fast, the ratchet wheel cooperating with a pawl 67 for rotating the ratchet wheel and the feed roller connected therewith in the desired direction, The pawl 67 is swingable on a pin 68 which is inserted in the flange 64. A spring 69 having an end connected with the pin 68 and an end connected with the pawl 67 assures engagement of the pawl with the wheel 66.
The rear end of the segment 61 is provided with an angular protuberance 70 having a radial portion continuing into a portion which is parallel to the pin 15 and forms a handle. A bore 71 is provided in the top of the protuberance 70 for receiving the end 72 of a spring 74 which is wound around a pin 73 pivotally connecting the lateral cheek 12 of the upper nipper with the link 21 which is swingable on the oscillating drive shaft 10 for the nippers. The free end of the spring 74 rests on a flange of the arm 12. The spring 74- urges the upper free end 75 of the segment 61 to abut against the arm 12 so that the segment 61 rotates through the same angle as the upper nipper arm 12 rotates relatively to the bottom nipper 3.
in order to protect the pawl and the rachet wheel against dust and fly a shell may be provided as indicated by dash-dot lines in FIG. 1.
The device operates during each combing cycle as follows: Feeding begins shortly after the nippers have left the forward dead center position and continues until the .3 nippers are closed. As seen in FIG. 2 nipper closing movement of the lateral arm 12 of the top nipper produces a counterclockwise rotation of the segment 61 and a clockwise rotation of the gear 63 and of the pawl 67 mounted thereon. Upon engagement of the pawl 67 with the ratchet wheel 66 which is fast on the feed roller 23 the latter moves synchronously with the top nipper, however, at a speed corresponding to the gear ratio of the segment 61 and of the gear- 63. When the nippers are closed there is no movement of the top nipper relatively to the bottom nipper and consequently no rotation of the feed roller. After the nippers are reopened'when moving from the rearward to the forward position the segment 61 rotates clockwise due to the action of the spring 74, causing sliding of the pawl 67 on the ratchet wheel 66 which is, at this time, not rotating until the movement of the nippers is again reversed.
Feeding by hand is effected as follows: The protuberance 70 of the segment 61 is pressed in counterclockwise direction against the action of the spring 74 until the protuberance 70 abuts against the surface portion 76 of the arm 12. The feed roller is thereby rotated in the feeding direction in the same manner as if the arm 12 rotates the segment 61 by abutting against the upper end '75 of the toothed portion 62 of the segment 61. Return of the upper end 75 of the toothed portion 62 of the segment 61 after the latter has been turned counterclockwise by hand is effected by the spring 74, whereupon hand feeding can be repeated by again pressing the protuberance 70 in counterclockwise direction.
The aforesaid drive mechanism of the feed roller affords convenient removal of the feed roller 23 without special tools. For this purpose the joint formed by link 21, pin 73, and arm 12 is pressed down as seen in FIG. 2 until a labile dead center position is passed and a pin 77 extending laterally from the arm 12 engages the hook at the upper end or" a spring 46 pulling the spring 46 away from the feed roller .23 so that the latter can be removed by rolling its gear 63 upwards on the toothed portion 62 of the .segment61'and out .of the recesses 24' (FIG. 1) in the top of the lateral arm 2 of the bottom nipper 3. The spring 46 is connected with a hub portion of the arm 2 of the bottom nipper 3 which arm is mirror symmetric to the arm 1 which is shown in FIG. 2. The spring 40 engages and normally presses the feed roller 23 into the recess 24.
In the modification of the drive of the feed roller 23 shown in FIG. 3 a gear 63 is freely rotatable on a boss 65 projecting from the end of the feed roller 23. The gear 63 is integral with a double disc wheel 78 having two discs 79 and 8% between which a pawl 31 is located which is pivoted to the discs 79 and 80. The pawl 81 is resiliently urged to swing outwardly by conventional means, not shown. A drum 82 which is provided with a hub 88 having an internal thread 83 is screwed onto the threaded end 86 of the boss 65. The drum 82 has a cylindrical shell 84 whose interior diameter is somewhat greater than the outside diameter of the wheel 78. The shell 84 surrounds the double disc wheel 78. The interior of the shell 84 is provided with teeth 85 adapted to be engaged by the pawl 81 when the wheel 78 is rotated in clockwise direction. The double disc wheel 78'is rotatable on the boss 65 whereas the drum 82 is rigidly connected with the feed roller 23. The shell 84 forms a cover for the pawl 81 which is in a cylindrical box closed in the direction towards the feed roller 23 by the disc 79 which is separated only by a small clearance from the shell 84. The axial position of the drum 82 is assured by abutment of the hub 88 against the double disc wheel 78 and gear 63 and .by abutmentof the latter against the shoulder between the boss 65 and the feed roller 23. The arrangement shown in FIG. 3 affords quick connection and disconnection of the internally toothed drum 8.2
to and from the feed roller- This is important, if it is desired to change the rate of feed by using a ratchet wheel having a greater or smaller number of interior teeth. Otherwise the operation of the embodiment shown in FIG. 3 is the same as that shown in FIGS. 1 and 2.
