Abstract: 825,506. Sewing machines. DURKOPPWERKE A. G. Aug. 23, 1956 [Aug. 25, 1955], No. 25731/56. Class 112 In a multi-needle sewing machine the needle bars are reciprocated by a crosshead, coupling means operating between one or more of the needle bars and the crosshead are located within the respective needle bar which latter also has an uncoupling member within, and said member extends from the top of the needle bar for selective operation by obstruction, whereby one or more of the needle bars may be coupled or uncoupled to and from the drive selectively. Tubular needle bars 3, 4 are driven by a crosshead 6. Each needle bar contains a conical member 32 connected by an upwardly projecting stem 41 to a sleeve 42. A rod 39 has its lower end seated in sleeve 42 and its upper end projecting through a screw plug 40 at the top of the needle bar. A compression spring 43 is interposed between sleeve 42 and a collar 39<SP>1</SP> on rod 39. A compression spring 36, positioned at the bottom of the needle bar, exerts upward force on bar 39 via a head 37 and a stem 45 extending downwardly from the latter, a block being interposed between spring 36 and stem 45, and a compression spring 35 being interposed between head 37 and a conical member slidable on stem 45. The arrangement is such that member 32, under the influence of spring 36, normally urges three balls 31 radially outwards through holes in the needle bar to engage a conical seating 34 at the bottom of crosshead 6 to lock the needle bar thereto. Slidably mounted on a horizontal pin 9 is a block 10 having a depending finger 10<SP>1</SP> which may be moved over either of the needle bars, whereby, when the selected one of the latter rises to its topmost position, rod 39 is moved downwards to displace member 32 for freeing the balls 31, and member 46 displaces balls 44 outwardly into engagement with a conical seat 48<SP>1</SP> in the machine frame to lock the disconnected presser bar to the latter. The arrangement is also such that member 46 rises on stem 45 to compress spring 35 and to raise the needle bar slightly higher than its normal top dead centre position. Sleeve 10 is moved by a finger carried by a boss 11 fixed by a screw 13 to a rod 12 biased to a middle position by a pair of opposed springs 20, 21. Rod 12 and the springs are mounted in a housing 19 which is pivoted to the machine head and is connected by a link 30 to a lever 17, 14 pivoted at 15 on the machine frame. Arm 14 is formed with a slot 56 embracing the shank of a headed stud 59 attached to a leaf spring 57 adapted to engage behind a pin 60 on arm 14, for holding the latter at either one of its two end positions. Pressure on head 59 releases the spring, whereupon casing 19 is returned to the neutral position by means of another pair of opposed springs mounted within.

Filed: 1956-08-23
Abstract: 788,150. Tube expanders and flangers; jointing by tube expanding. BABCOCK & WILCOX, Ltd. (Deutsche Babcock & Wilcox Dampfkesselwerke). Aug. 23, 1956, No. 25737/56. Class 83 (4). A tool for the expanding of a tube end within a tube hole in a plate includes withdrawal means for the forcible pulling-out from inside the tube end of tube expanding means adapted during withdrawal to expand the part of the tube within the hole, the withdrawal means being arranged during withdrawal to operate belling means which effect belling of the free end of the tube. In operation an expanding tool 10 is positioned with a bearing surface 12 engaging a face 5 of a tube plate 3, into a hole 2 in which the end of a tube 1 is to be expanded. An expanding tool mandrel 14, formed with a tapering part 16, is inserted in the tube end, a sleeve-like stop 30 slidable on the cylindrical part of the mandrel 14 being set with its shoulder 34 forwardly of inwardly spring-urged radial plungers 36, and two pairs of expanding members 21 being towards the smaller end of the tapered part 16 of the mandrel 14. One opposed pair of expanding members 21 is staggered axially relative to the other pair and abuts the end of a flared forward part 32 of the stop 30, the four expanding members being held together and on the mandrel by an encircling spring 24. The mandrel 14 is then drawn rearwardly, by hydraulic means, through the body of the expanding tool 10, thus causing the members 21 to move outwardly and into alignment with one another and expand that part of the tube lying immediately outside the plate 3. When a head 15 on the mandrel 14 engages the members 21 the sleeve 30 is moved rearwardly, the plungers 36 riding up over the shoulder 34, together with the expanding members 21 which effect the progressive expansion of that part of the tube 1 lying within the plate 3. As the members 21 approach the face 5 of the plate 3 the flared part 32 of the stop 30 engages inclined surfaces 42 upon eight belling elements 40 to move these elements radially outwards, against springs 41, so that tongues 4 thereon engage and bell outwardly the projecting inner end 4 of the tube 1. The head 15 may be adjustable along the mandrel 14 so that the limit of the outward movement of the expanding members 21 may be adjusted, the members 21 in this case preferably being of piston-ring shaped overlapping design.
