Title: Shuttle-bobbin-changing mechanism for automatic looms with two or more coaxial pivoted magazines
IPC: D03D43/00
Filed: 1926-11-09
Abstract: 261,374. Maschinenfabrik R³ti vorm. C. Honegger. Nov. 10, 1925, [Convention date]. Shuttles, changing bobbins in, automatically. -In bobbin-changing mechanism of the type wherein two or more coaxial magazines 3, 4, 5 pivoted at 2 so as to be movable independently of one another are used, the magazines are so arranged that the angle x<0> at which the second lowest bobbin in each magazine slides down to the position occupied by the lowest bobbin is the same in each compartment. The lowest bobbins of all the groups of bobbins at the same side may be arranged in radial register relatively to the pivot 2 by making the bounding walls 6, 7, 8 between which the bobbin ejector 9 can pass in the position of rest of increasing thickness outwards as shown. Stops 10-15 on the magazines coact with a fixed abutment 16. The bars 17, 18, 19, which receive a vibratory motion determined by the shuttle changing mechanism, act on the various magazines at the same distance from the common axis 2, the bar 17 engaging a pin 20 secured to the magazine 4, the bar 18 engaging a pin 22 coaxial with the pin 20 and connected by an arm 21 to the magazine 3, whilst the bar 19 engages with a pin 24 also coaxial with the pin 20 and connected with the magazine 5 by an arm 23. In a modification, the parts of the magazines adjoining the walls 6<1>, 7<1>, 81, Fig. 5, are shaped to depart so far from the circular form as to make the angle x<0> constant. In this case the ejector 9<1> is vertically guided and is operated by a slotted bell crank lever 9<4> pivoted at 9<2> and a thrust rod 9<3>, which is actuated by the lay.

Title: Improvements in means for adjusting the maximum and minimum limits for an indicating pointer having means for electrically controlling levels in a hydraulic or other liquid system
IPC: G01F23/18
Filed: 1932-10-12
Abstract: 413,004. Indicating &c. ROSE, S. A. M., 111, Gray's Inn Road, London. Oct. 12, 1932, No. 28376. [Class 106 (iv).] In indicating and/or measuring instruments comprising means for controlling electrically other apparatus according to the magnitude of a high and a low reading or measurement, means is provided on the outside cover, casing, or face plate for facilitating manual adjustment of the high and low limits from the outside of the instrument, such that, when the outside cover is placed on the instrument the electrical connections of the control circuits are completed, and when the cover is withdrawn they are broken, the arrangement being such that no terminal or connection is carried on the covers other than those provided in the manual adjustment device. The pointer 10 of the instrument, electrically in circuit with a terminal 15 at the back of the instrument, carries a pin 9 adapted to contact with a low limit contact arm 2 or a high limit arm 2<a>. On the push-on cover 11 (for example a glass face) is mounted, coaxially with the instrument pointer, a bushing 12 carrying coaxially rotatable on it a knob 4 for rotating a sleeve with an arm 8 carrying a pin 6 against which is pressed by a hair spring 7 the low limit arm 2, also coaxially rotatably mounted on the sleeve of the knob 4 as shown. A similar knob 5 similarly gives setting to the high limit arm 8<a> with its pin 6<a> to position similarly the high limit arm 2<a> which affords contact to the indicator pin 9. The arms 2, 2a are in frictional contact with resilient conducting members 1, 1<a> held fixed in position by an insulated pin 17 to a lug 18 on a washer 19 clamped to the casing face 11 by a nut 12<1>. The resilient members 1, 1<a> have holes to engage conical and shouldered ends on posts 13, 13<a> connected in circuit with the terminals 14, 14<a> at the back of the instruments. Thus the cover on withdrawal removes the resilient conductors 1, 1<a> from the posts to break the circuits and on replacement re-establishes the circuits.
