Abstract: 563,079. Spinning frames; creels ; cleaning machines.SACO-LOWELL SHOPS. March 7, 1942, No. 3014. Convention date, July 16, 1941. [Classes 120 (ii) and 120 (iii)] In a double-sided spinning frame with a creel having at least two horizontal rows of roving bobbins, these rows of bobbins are mounted closely adjacent to and directly over the two sets of drawing rollers, and the back rows of each set of rollers are set closely together and separated by a space narrower than the overall lateral width of either set of rollers and too narrow to accommodate a creel ; this arrangement allows the width of the frame to be reduced by approximately one-half. As shown, Figs. 2 and 3, there are two tiers of bobbins and the lowermost rows B are located above the drawing rollers 6 with the inner row B<1> of the upper tier located above the row B and an outer row B<2> comprising a smaller number of bobbins spaced outwards from the row B<1>. The frame may be of the construction described in Specification 550,248 and the creel comprises sections disposed over each section of the frame and supported by posts 7, 8 mounted at the opposite ends of a section of the frame. The posts are connected by a horizontal bar 10 through which cross-bars 12 are secured for carrying the bobbins mounted on tubes b, Fig. 6, which have an internal shoulder at the end. The upper rows B<1>, B<2> of bobbins are supported on shouldered caps 22 rotatably mounted on taper ended posts 21 projecting upwards from a member 14 secured to a bar 12, the bar passing through the member which projects above and below the bar ; the posts 21 supporting the bobbins of the outer rows B<2> are carried by members 25 fitting on the ends of the bars 12. The depending part of the member 14 carries a fixed stud 15 on which a bushing 16 carrying a cap 17 is rotatably mounted and each bobbin of the lower row B is secured to a cap by spring-pressed plungers 18 in the cap engaging below the shoulder in the tube b. The yarns from the bobbins are guided by mils 26, 27 carried by vertical bars 28 secured to the bars 12, the rails of abutting sections of the frame being secured together by sleeves 30. The bars 10 are connected to the posts 7, 8 by straps 32 clamped around the post by screws and having projecting ends engaging slots 31 in the ends of the bars with a pointed screw threaded into an enlargement of each slot engaging between the lower edges of the ends of the strap and exerting a spreading action on them. Certain of the bars 12 are longer than the others to support the bobbins B<2> which are thus spaced outwards from the bobbins B<1> and the longer bars 12 are so spaced relatively to the shorter bars that free access is had to all the bobbins of the inner rows. The frame is kept clean by covering the space between the spindle with a smooth plate 36 which preferably overlaps hinged L-shaped parts 37<1> of plates 37 enclosing the base of the frame and it is found that the lint and fly is prevented from coming to rest in the space by the air currents created by rotating bobbins and spindles ; the abutting edge of adjoining side plates 37 are covered by strips 41. Specifications 3316/07, [Class 130], and 572,593 also are referred to. The Specification as open to inspection under Sect. 91 comprises also an arrangement of thread lappets which are in sections carried by cylindrical bars 5, Fig. 11 (Cancelled), which are connected at adjoining frame sections by a two-part clamp 51 secured to a vertical post 50 and carrying a disc between the parts of the clamp with diametral tongues on opposite sides of the disc at right angles to one another engaging grooves formed in the ends of the bars so that prior to doffing, all the bars may be turned from one end of the frame to swing all the lappets of the frame upwards. Each lappet includes a thread guide 43 adjustably secured in a bushing 44 by a screw 45, the bushing being rotatably mounted on a sleeve 46 secured to the rod by a screw 47 ; the movement of the bushing is limited by a slot therein engaging the screw 47. This subject-matter does not appear in the Specification as accepted.
