Title: Seamfree stockings and methods and machines for manufacturing the same
IPC: D04B9/18
Filed: 1961-12-11
Abstract: 1,013,784. Knitting. EUNOSTOCK ANSTALT. Dec. 11, 1961 [Oct. 12, 1961], No. 44158/61. Headings D1C and D1K. A seam free stocking fabric comprises a series of pairs of courses of which one course consists of plain stitches and the following course consists of plain stitches alternating with tuck loops, the stitches in the second course being so much larger than those of the first course that the held loops 1 of the first course are enlarged at the expense of the remaining stitches of that course which are pulled straight as at 2 the tuck loops being periodically shifted course wise by one stitch. As shown, loops 1 are doubled back about the part 2 and the limbs of loop 1 are locked by the centre of the next loop 3 which is doubled back about a straight part 4 of yarn. Every eight (or four or 2) courses the pattern shifts one stitch course wise to form a transition point A, Fig. 1. As shown, a two feed circular knitting machine has latch needles 13 with jacks 14 having butts alternately at two levels over a quarter of the circumference of the cylinder and alternately at two higher levels over the circumference. The jacks 14 and hence needles 13 are selected by cams 20 controlled by a cam drum 19, the cams 20 being put into operation over the part of the circumference in which there are no corresponding butts. Plain knitting, As well as reciprocation knitting for the formation of the heel and toe, takes place at feed I whereas the courses of plain stitches and tuck loops are formed at feed II. The sinker cam 24 at feed II is radially movable and has guide surfaces 26, 27, which co-operate with sinkers having long and short butts respectively so that the long butt sinkers more normally but the short butt sinkers engage their webs under the yarn being fed. Thus the loops formed in this course are larger and the held loops of the previous course are pulled out to match at the expense of the remaining stitches in that course which disappear. Alternatively, machines have a single feed or more than two feeds may be used. Synthetic and mixed yarns of 7 to 100 denier may be used.

Title: Friction ratchet jack
Inventor: TROMMLER JUERGEN
IPC: B66F1/02
Filed: 1966-10-05
Abstract: 1,134,553. Friction ratchet jacks. PKM HYDRAULIK KARL - MARX - STADT VEB. 5 Oct., 1966, No. 44480/66. Heading B8J. A friction ratchet jack adapted to move a shaft 3 or carry out a displacement movement relative to a stationary shaft or to be locked to the shaft comprises two clamping plate assemblies which work against each other, each assembly being arranged in a housing 4, one of which assemblies comprises a support clamping plate 5, a clamping plate 6, a spring 7 and an operating lever 8. The other assembly comprises similar members 9, 10, 11 and 12 and the two assemblies are arranged to work against one another. Each lever 8, 12 is pivotally connected to its associated clamping plate 6, 10 and has a cam end portion which engages a roller provided on the associated support clamping plate. Arranged on the support clamping plates 9, 5 are piston and cylinder devices 1, 2 respectively connected by bolts 14 to the operating levers 8, 12. A lever 15 is connected to each operating lever 8, 12 to permit manual operation of the jack. If the piston and cylinder device 1 is extended from the position shown by the application of fluid pressure the cylinder will move upwards initially a short distance to cause the support clamping plate 9 to abut against a stop 13, discontinuing the clamping action of the support clamping plate 9 and the clamping plate 10. Further extension of the piston and cylinder device 1 results in the movement of the shaft 3 downwards a short distance, clamping plate 6 being securely clamped. On the return stroke of the piston and cylinder device 1 the shaft 3 is locked in both directions by the support clamping plates 5, 9. The shaft 3 may thus be lowered any desired amount by repeated strokes of the piston and cylinder device 1. Similarly, operation of the piston and cylinder device 2 raises the shaft 3. If, for example, the piston and cylinder device 1 fails, removal of the bolt 14 and release of the support clamping plate 9 allows the shaft 3 to be moved downwards by means of the lever 15.

Title: Slicing machine
IPC: B26D7/32
Filed: 1963-11-11
Abstract: 977,790. Slicing machines. T. G. WERDER, and H. O. SCHUETZE Nov 11 1963, No. 44504/63. Heading A4C. A machine for slicing meat loaves 15 &c. comprises a feed carriage 14 having opposed chain conveyers 93, 96 between which loaves 15 are fed downwardly to be sliced by a spiral, rotary knife 26 located above a table 25 having a discharge port 25a through which slices 16a pass to be stacked on a vertically movable platform 40, means for intermittently driving the conveyers 93, 96 and lowering the platform 40 each time the knife 26 rotates beneath the carrier 14, and means including a cam 51 for axially moving the knife shaft 31 to vary the spacing of the knife 26 from the table 25 and hence the slice thickness, the latter means also serving to vary the magnitude of the incremental movements of the conveyers 93, 96 and platform 40 to substantially equal the knife 26 and table 25 spacing. The table 25 and knife 26 are continuously rotated together by a motor 35 and drive belt 37 to cut slices 16a which are stacked on the rake-like platform 40 which is successively lowered to a position in which the platform fingers 44 pass between spaced chains 45 of a discharge conveyer 18 which carries the stacks 17 past a check-weighing scale 19 to a packaging conveyer 20. A shear block 14a on the carrier 14 serves to hone the knife 26. The conveyers 93, 96 are driven from a rack 112 biased by a spring 122 acting through a pinion 114 to engage a cam 110 carried on the knife shaft 31, the drive shaft 115 acting through a one-way clutch 121 to incrementally drive a shaft 115a which, as shown in Fig. 9, in turn is geared to drive the conveyers 93, 96 and the platform 40. An intermediate drive shaft 120 for the platform 40 includes an electric clutch 142 which is normally engaged but which is automatically disengaged in dependence upon the setting of a slice counter 140 whereby simultaneous operation of a motor 141 acting through a chain drive 143 serves to rapidly lower the platform 40 so that a stack 17 is discharged, an electromagnet 148 being arranged to prevent rebound of the platform 40 and the latter being returned to its elevated position by a spring 155 in readiness to receive the first slice of the next stack 17. The control arrangement is such that rotation by means of a control knob 55 of the shaft 54 of the slice thickness adjusting cam 51 also serves by means of a stop block 136 threaded on the shaft 54 to limit movement of the rack 112 and hence the magnitude of the incremental movements of the conveyers 93, 96 and platform 40 whereby these movements are directly related to the selected slice thickness. During feeding of the loaf 15, the latter is gripped between the walls of an L-shaped trough 70, a spring 77 biased movable wall 71 and a spring 84 biased shoe 82.
