  • Corresponding whirls IS on opposite sides of the machine are rotated by belts 2
  • the drum 22 rotates about a fixed axis and is mounted on a shaft 23 supported by a frame structure 24 disposed beneath the drum and rigidly fixed to the frame 9 of the machine.

  • the run of the belt passing over the drum 22, which run will for convenience be indicated as 25 is urged downward onto drum 22 by means of pulleys 26 and 21 mounted on 0pposite sides of the drum.
  • Pulley 26 is supported by arm 28 mounted on a rod 29 connected by bracket 3
  • Rod 29 which may extend between and be connected to spaced cross members l of the reciprocatory frame, may conveniently support corresponding pulleys 26 for adjacent belts.
  • Pulley 21 is mounted on the arm nected'to the stationary frame structure 24, as by brackets 34.
  • Rod 33 like rod 29, may extend lengthwise of the apparatus and support corresponding pulleys 21 for adjacent belts.
  • Pulley 31 is mounted on arm 38 carried by rod 39 mounted by bracket 40 on cross member l5.
  • rod 39 for pulley 31 may extend lengthwise of the apparatus and be supported by the other cross member l5 included in the recipro- 39 may therefore be used to support corresponding pulleys 31 for adjacent belts 2
  • Pulley 36 is designed to maintain a substantially constant tension on belt 2
  • pulley 36 is mounted on an arm 4
  • a tension member such as cable 44 passingover sheave 45 mounted on bracket 42 is connected at one end to the pivotally mounted arm 4
  • Pulleys 26 and 31 for opposite runs of the belt are mounted to move in unison with the lifting rails and in fixed relation with'respect to the plane of the belt starting on the whirls. These pulleys are shown as mounted in fixed relation with respect to the lifting rails 5, although they might be suitably movably mounted thereon to take up slack in the belt without interfering with their guiding function.
  • the pulleys 21 and 36 are supported by the rigid frame of the machine and aid in increasing the angle of wrap of the belt around the driving drum 22. In the illuspulley 26 also performs this function.
  • pulleys 26 and 31 serve to guide their respective runs of the belt 25 and 35 onto the whirls l3 toward which the belt is passing, since said pulleys are fixed to and move downward with the lifting rails l5.
  • pulleys are fixed to and move downward with the lifting rails l5.
  • the belt is at all times positively guided as it starts on the whirls and consequently moves in a fixed path'with respect to each whirl toward which it is traveling. Furthermore, during such reciprocation the tension pulley 36 moves to take I belt caused by the reciprocation of the lifting rails, as shown by the positions indicated in full and dotted lines in Figure 3, thus maintaining a substantially constant tension in the belt.
  • the arrangement of the pulleys is such that very little change occurs in the angles of wrap of the two runs of the belt on the drum.
  • each run of the belt there is obtained a substantial degree of wrap of each run of the belt around driving drum 22 as a result of the fact that at least one pulley contacts each of the runs of the belt and causes it to wrap around said driving drum in an open loop in the bight of which is disposed the driving drum itself.
  • an open loop is meant a loop such that the run of the belt does not cross upon itself in such manner as to enclose the driving drum completely. Since neither run of the belt crosses upon itself, all portions of each run of the belt, whether in contact with or in the immediate vicinity of the drum, are disposed in a. plane perpendicular to theaxis of rotation of the drum,
  • pulley 36 is dis- To change the direction of rotation of the whirls, the various pulleys 26,. 21, 36 and 31 may be moved lengthwise of the driving drum 22 to positions in which they are in contact with the runs of the same belt opposite from the runs which they originally contacted. This may be accomplished by bodily sliding lengthwise of the drum the various rods 29, 33, 39 and 43 supporting the pulleys and thepulleys supported thereby. This end can be effected by loosening the brackets 3
  • runs of the belt should be interchanged with respect to the drum; that is, the run which originally passes over the drum should be passed under the drum and the run which passes under the drum should be passed over the drum.
  • This may readily be accomplished without severing the belt after the belt has been removed from the pulleys so that it is slack, by lifting the belt from the whirls at opposite sides of the apparatus, and turning the belt over bodily so that the runs are interchanged.
  • the direction of rotation of the spindles will be changed although the direction of rotation of the driving drum 22 is the same.
  • the reciprocatory frame conprising lifting rails 5 and cross members 15 is moved up and down by means of flexible tension members 41, such as chains, each fastened at one endto one end of the cross members I 5and at the other to a sprocket 48 (Fig. 2) rigidly fixed to a shaft 49 extending longitudinally of the apparatus along each side thereof.
  • Each such shaft 49 may be connected by such tension members 41 to a plurality of cross members l5 disposed at intervals along the length of the apparatus.
  • Each of said shafts 49 may have rigidly connected thereto one or more sprockets 5
  • the tension members 41 and 52 for each shaft 49 are, as shown, mounted on their corresponding sprockets on'opposite sides of said shaft 49 so that as one unwinds from its sprocket the other winds on its corresponding sprocket.
  • the counterweights 53 serve to counterbalance a portion of 'the weight of the reciprocating parts.
  • the shaft 49 on the left-hand side of the machine in the-figures is provided at one end with a sprocket 54 (Figs. 2 and 5) having connected thereto and adapted to wind thereabout a tension member 55 which is connected at its other end to a lever 56.
  • One end of lever 56 is connected to said tension member 55 while the other end is pivotally mounted as at 51 on the frame 9 of the machine.
  • the drive end of the frame 9 of the machine is provided with a housing 58 on which the lever 56 is pivotally mounted and which further rotatably carries a suitably shaped cam likewise rigidly mounted on the back of said housing 58.
  • Motor 63 drives speed reducer 62,
  • the present invention thusprovides spindle driving apparatus particularly adaptable for use in cases in which the spindles are mounted on reciprocatory frames, which apparatus is simple in construction, efficient in operation, and, because it provides a design in which the opposite runs of the belt travel in spaced, substantially parallel planes, minimizes belt wear due to excessive bending of the belt in the plane of the belt. Since both runs of the belt maybe positively driven by the driving drum, belt slip is reduced to aminimum. While the lifting rails on opposite sides of the apparatus are shown as connected together by cross members, it is apparent that this is not strictly necessary, since the lifting rails may be otherwise moved in unison.
