Definitions

  • each of the toothed wheels serving as the gearing for the spindle or stud carriers is provided with a trunnion or hub which allows it 6' to rotate in a suitable hole or bearing in the plate carrying the gear wheels and also in a hole or hearing formed in a ring or flange completing the said plate and made integral therewith, for example, by forming part of the same casting.
  • holes or bearings can be formed in bosses or distance pieces provided on the plate.
  • the toothed wheels transmitting motion to each stud have helicoidal teeth which ensures a proper and continuous engagement of adjacent wheels and consequently a progressive transfer of the studs from one wheel to another.
  • the core carrying thread guides are secured at their lower ends by a hollow screw serving as a plug, the hubs of the toothed wheels being in this case suitably perforated.
  • the machine which is the subject of this invention is clearly distinguished from prior machines by the construction and operation of these gears. It allows defects of operation observed in other machines with travelling spindles or studs to be avoided, for example, the shock of the spindle or stud striking against the guide grooves v 1 at the crossing points which results in a rapid attrition of the guides, this result being obtained by making the guide grooves with contours such that the movement of the spindle is along a straight line at these crossings.
  • Figure 1 is a plan of the gears.
  • Figure 2 is a side view thereof.
  • Figure 5 is a view of the underside of the plate partly in section on the line 5-5, Figure2.
  • Figure 6 shows a transverse section similar to that shown in Figure 4 illustrating a modified arrangement.
  • the braiding machine comprises a plate A of suitable profile cast integrally with a second perforated plate or ring A, forming a flange; in the plate A, in a known manner, grooves E are formed to guide the studs during their movements and serve as a track for these studs ( Figures 3, 4 and 6).
  • the said ,grooves are arranged in such a manner that at their crossings the stud is moving along a straight path and does not strike against angular parts so as to cause rapid deterioration of the studs as is the case in other known machines with travelling studs.
  • These grooves can be cast in the plate but are preferably formed by a milling operation.
  • the plate A are mounted sets of gearing comprising a convenient number of toothed wheels Z each provided with a trunnion or hub C serving as a pivot which passes through a hole or-bearing I and is rotatably stepped in a blind circular hole ,or hearing I provided in the ring or flange A, carried below the plate A.
  • the toothedwheels Z. are rotatably supported by their trunnions or hubs C mounted in the holes or bearings I and I and thus it is not necessary that they should be of a great width. This makes 8 for a light construction of the machine whilst on the contrary in other machines with the usual gearing in order that they may be sufllciently stable and rigidly supported on the spindles the toothed wheels are made large and heavy; more-, 85. over such toothed wheels "have straight teeth which are thin and consequently relatively weak.
  • a plate or wheel B is provided having helicoidal teeth which are so milled while the notch D is so cut that in each case the tooth corresponding to the notch D is not entirely but only in part cut away.
  • the slot or notch D has substantially equal tooth portions disposed at the sides thereof. In this manner adjacent toothed wheels are in permanent mesh and the spindle is guided properly and silently from one to another tooth or notch.
  • the machine is thus less cumbersome, is simpler and has no screws or nuts on its upper part.
  • Figure 6 shows another constructional form oi' themachine in accordance with this invention in which in place of the flange A, completing the gear carrying plate at its lower part, spaced distance pieces A are provided which are bored and guide the hubs of the toothed wheels throughout their length.
  • a braiding machine provided with a plurality of meshing gears havingperipheral openings and adapted to drive and support the studs 0! the machine, means for'insuring the meshing of said gears in spite of the presence of the openings therein including helical teeth upon said gears, a guide plate having grooves to guide said studs, downwardly extending hollow pins for journaling said gears to said guide plate, a flange secured below said plate and also supporting said pins, thread guides extending through said pins and projecting upwardly therefrom, and means securing said thread guides to the lower portion of the guide plate.
  • a braiding machine according to claim 1, wherein the downwardly extending pins or the toothed wheels are hollow, and the machine is provided with thread guides extending through the hollow pins and projecting upwardly therefrom and means securing said thread' guides to the lower portion of the guide plate.
  • a braiding machine according to claim 1, wherein the downwardly extending pins or the toothed wheels are hollow, and the machine is provided with thread guides extending through the hollow pins and projecting upwardly therefrom and axially hollow screws directed upward from the underside of the guide plate securing said thread guides thereto.
