Definitions

  • Another object is to provide an improved .cushioning medium for the equalizing device which medium will not be subject to loss or dissipation.
  • Another object of my invention is to reduce the unit cost of rayon spinning by reducing (1) the frequency of the periods of enforced idleness of the apparatus, and (2) the labor and material used in repairs during such periods.
  • FIG. 1 is a broken elevation view of a combined filter and equalizing chamber embodying my dinal midsection.
  • Figure 2 is a midsection view of the equalizing device shown in Figure 1, but showing the position of the parts when under working pressure.
  • Figure 3 is a midsection view like Figure 2 but of a modified equalizing device constructed according to the principles of my invention.
  • Figure 4 is a view similar to Figure 3, but showing the device of Figure 3 as it appears when subjected to working pressure.
  • Figure 6 is a view similar to Figure 5, but showing the device of Figure 5 as it appears when subjected to working pressure.
  • the casing 10 for a conventional filtering device 12 has, at one end, a reduced neck 14 with a central bore therethrough, and an enlarged head 16 screwed into the other end.
  • the head 16 has a central passage 18 communicating with a similar passage 20 in the filter 12.
  • Passage 18 leads to the passage 20 from one side of the bottom of a screw threaded well, in which are secured a flexible diaphragm 22, preferably of rubber, and a hollow, semispherical cover 24 having an outtumed flange 26 which is engaged by the bottom of a threaded collar 28 screwed into the well to hold the cover and diaphragm in place.
  • an air filled chamber 29 which acts as a cushion for the diaphragm, is provided between the cover and diaphragm.
  • the viscous mixture flows beneath the flexible diaphragm 22 from a passage 30 leading into the bottom of the well at the oppostarts to flow through the device the pressure applied to it by the usual pump (not shown) causes the diaphragm to bulge, as it tends to assume a semi-spherical shape.
  • the small end of the spring seats in the top of the cover around a teat 34 in the center of the cover, while the large end of the spring seats in a metal cap 36 which rests upon the center of the diaphragm.
  • This cap 36 is preferably circular with its periphery turned up to counteract any tendency of the spring to slip off it or the cap to cut the diaphragm.
  • the cap also is made slightly concave, as shown in Figures 1 and 2, to accommodate and co-operate better with the diaphragm when pressure is applied thereto under working conditions.
  • Figures 3 and 4 show another form of diaphragm support or cushion comprising a truncated-conical rubber block 40, the smaller or upper base thereof, having a depression for the teat 34 of the cover while the lower or larger base rests on the diaphragm.
  • Fig. 4 shows the form taken by the block 40 when the equalizer is subjected to working pressure. 1m
  • Figures 5 and 6 show a third fcrmof the invention in which the cover is filled with a sponge rubber filling 50, Figure 6 showing the form assumed by this device when subjected to working pres sure.
  • the cover may be provided. with a vent hole 25 such as is shown in Figs. 5 and 6 for the air within the cover.
  • a vent hole 25 such as is shown in Figs. 5 and 6 for the air within the cover.
  • an equalizing device for dampening the pulsations from the pump com- ,prising a hollow cover, a flexible diaphragm beneath and engaged by the periphery of said cover forming a chamber between the cover and diafor dampening the pulsations from the pump,
  • anequalizing device for dampening the pulsations from the pump, comprising a hollow cover, a flexible diaphragm beneath and engaged by the periphery of said cover forming a chamber between the cover and diaphragm, said diaphragm being in the direct line of flow of said solution between said pump and spinneret, and a conical coil spring in said chamber supporting said diaphragm.
  • an equalizing device for dampening the pulsations from the pump comprising a hollow cover, a flexible diaphragm beneath and engaged by the periphery of said cover forming a chamber between the cover and diaphragm, said diaphragm being in the direct line of -flow of said solution betweencsaid pump and spinneret, a coil spring in said chamber supporting said diaphragm, and a disc seat for the end of said spring at thediaphragm.
