Title: Improvements in or relating to linear-dimension gauges
IPC: G01B3/22
Filed: 1946-04-10
Abstract: 610,585. Linear-dimension gauges; indicating- apparatus. SIGMA INSTRUMENT CO., Ltd., and BOOSEY, F. R. April 10, 1946, No. 11070. [Classes 106 (ii) and 106 (iv)] The indicating-apparatus of a comparator or other linear-dimension gauge has two pointers 15, 24 of different sensitivity actuated by a lever 8 pivotally mounted on axis 9, 9 and provided with a knife-edge disc 7 in contact with a member 6 secured to a plunger 5 which is in contact with the feeler 2 of the gauge, the pointer 24 indicating to an enlarged scale a small selected range of movement of the pivoted lover 8. The free end of lever 8 contacts a knife-edge member 16 adjustably carried by a cam disc 17 rotatable about axis 19, 19. A strap 20 secured to and passing around the cam 17 is secured to the free end of a leaf spring 21 which tends to turn the cam about its axis so that member 16 follows the free end of lever 8. The pointer 24 is secured to the cam 17. The pointer 15 is connected to a point between the free end and pivot of the lever 8 and follows all movements of the latter: the pointer 24 is actuated only during the time the member 16 engages the free end of the lever 8. Springs 11, 13 maintain the disc 7 in engagement with the member 6. To facilitate zero adjustment of the pointers, the lover 8 is pivoted in a bar 30 which can be flexed by a rod 32 adapted to be moved by rotation of a screw 33. By passing the band 20 around the cam 17, the varying pressure exerted by the deflected leaf spring 21 is compensated, so that there is a substantially constant pressure between member 16 and lever 8.

Patent GB-473365-A (GB)
Title: Improvements in or relating to the manufacture of circular knitted articles with pouches
IPC: D04B9/46
Filed: 1936-04-17
Abstract: 473,365. Knitting. WILDT & CO., Ltd., and HOLMES, H. H. April 17, 1936, No. 11082. [Class 74 (ii)] To overcome take-up difficulties met with, e.g. when knitting a continuous string of ribbed socks, various effects may be introduced in the waste fabric between one toe pouch 3 and the following rib top 4 to compensate for the presence of the pouch. Thus there may be partial courses 5a of slackened loops, put in mainly on the opposite side to the pouch. Or the character of the knitting may be varied, preferably on the same side as the pouch, by tucking, non-knitting or floating. The effects may extend over a constant number of wales or be graduated from course to course. As well as, or instead of, producing partial slackening some or all the heel and toe needles may suspend knitting for a few courses after the toe pouch is made, so that fewer stitches are formed in the fabric on the pouch side. Or, odd-numbered heel and toe needles may be caused to tuck or miss knitting in alternate courses while the remaining heel and toe needles do the same in the other courses of knitting. As applied to a machine of the double axially opposed needle cylinder type, the invention comprises a variable pattern cam for controlling the vertical movements of a block 10 which carries the stitch cams &c. A stud 30 on the main control drum 31 of the machine is movable radially by the variable cam mechanism and when it arrives under a lever 29, it operates on the block 10 through connections 16 ... 28, and causes a variable number of needles to draw longer loops. The drum 31 is formed with an extension 32, Fig. 9, into which projects a hub 33 keyed at 34a to the drum shaft 34. A cylindrical member 47, keyed to a sprocket wheel 36, driven from the main shaft is mounted on the end of the shaft 34. A drum 48 carrying cam segments 49 rotates with the cylinder 47 but is also moved axially along a spline 51, when a buttress thread 59 on the surface of the drum is engaged by a knife edge 60. When the drum has reached the end of its traverse the knife edge 60 is disengaged by a cam and the drum is returned to initial position by a spring. As the drum advances, the cams 49, which are so disposed as to leave an angular gap X, hold up the stud 30 for varying periods of time at each revolution of the needle cylinder and so cause the stitch cam to draw slack courses of variable length while the stud is under the lever 29. A device 52, 54 .. 58 interposed between the stud 30 and the drum permits the radial position of the stud to be adjusted. In another arrangement, not shown, a rotary cam unit having cam segments or sections one or each adjustable in a circumferential direction to provide a variable gap lowers the stitch cam for different lengths of time and the cam segments are adjusted automatically during rotation of the unit by pawl-and-ratchet or other mechanism. Specifications 15008/00, [Class 74], and 24290/12, [Class 74 (ii)], are referred to.

Filed: 1918-07-05
Abstract: 122,992. Jackson, W. J. Mellersh-, (Dentists' Supply Co.). July 5, 1918. Teeth, artificial.-A pin structure for artificial teeth consists of two metal prongs arranged adjacently to one another and of such cross-section that the outer surfaces of the combined pin so formed are flat, while the side surfaces are grooved longitudinally. In the example shown, the pin consists of a length of wire of semicircular section bent on itself at 7 so that the flat sides 5 are outwardly disposed and the curved sides 6 are in contact, thus forming longitudinal side grooves 10 bounded at the base of the pin by shoulders 7<a>. The pin is preferably bevelled at 8 so that the two prongs have a combined point 9 and cutting edges 8<a> arranged in the form of a cross. The pins are locked into the porcelain teeth or soldered to a platinum anchor therein, and in use are forced through a thin metal backing 11, and bent over as shown in Fig. 3, so that the flat sides come into close contact with the backing and may be soldered thereto. The tags or burrs formed on the backing by forcing the X- shaped cutting-edges of the pin therethrough are in part soldered beneath the bent-over prongs of the pin and in part forced in position between the curved surfaces 6 of the pin. A thick backing may be partly perforated by a separate tool before the pin is forced through it.
