Abstract: 419,234. Brush - making machines. CANIS, F., Crossen-on-Mulde, Germany. Oct. 6, 1933, No. 27583. Convention date, May 18. [Class 19.] In a machine in which the bristles are driven into the brush stock by wire loops forced home by a ram d, the mouthpiece b<1> which impinges against the stock is movable independently of the ram, and the latter during its movement is prevented from bending laterally by a guide e adapted to be swung into position near the portion d<1> of the ram. The guide is carried by a pivoted lever e' connected by a link g to a plate m rotatable about a pin i<1>. The plate m has a curved slot i adapted to be engaged by a pin o on a head b connected to the mouthpiece b<1>. The pin o also projects through a straight slot o<1> in a fixed plate a<1>. The arrangement is such that movement of the mouthpiece b<1> towards the stock causes the guide to swing towards the ram d.

Title: Improvements in automatic release mechanism for operating valves, switches, brakes and other mechanical devices
IPC: F16K31/46
Filed: 1924-11-21
Abstract: 248,048. Jones, C. E. Nov. 21, 1924. Actuated or applied by springs.- Relates to automatic apparatus for operating control devices, such as stop valves, and stated to be applicable also to brakes adapted to stop rotating parts, said devices operating by means of energy stored up in a spring or weight, means being provided whereby this energy can be released to operate the mechanism from a distance. As applied to a valve a', Fig. 2, the energy-storing spring s is disposed in a box e<1>, Figs. 2 and 4, mounted on pillars e<2> on a bridge nut a<8>, and on the valve spindle A<1> are mounted two concentric screwed sleeves B, F surmounted by upper and lower hand wheels C, G capable normally of free rotation relatively to the sleeves. Starting from the closed position, shown in Fig. 2, the valve a' is slightly raised and the spring fully wound up by engaging the wheel G to the outer sleeve F by the catch pin g<1> and then rotating the sleeve. The spring is held in the wound-up position by a catch-pin H, Fig. 4, which can at any time be released by a hand cam h<4>, or from a distance, such as by the cam and kicker lever K of the stop-motion releasing-device described in Specification 196,001, [Class 106 (i), Calculating &c.]. The rotation of the outer sleeve F in the nut E allows a spring d<4> to push up a plate D which carries upwards feather rods a<11> in feather-ways in the inner spindle A<1>, and with them a radiallyarmed clutch member C<1>. The arms c<3>, which extend through the cage b<1>, are engaged with teeth on the boss of the upper hand wheel C whose rotation thereupon rotates the inner sleeve B. and by means of the screw b<3> opens the valve, to any further extent desired. When the detent H, Fig. 4, is released, the spring rotates the outer screwed sleeve F, which runs down in the nut E freely until an upper toothed disc f<6> strikes the lower clutch disc b<5>; thereupon the inner sleeve B is rotated and screwed down in the bridge nut a<8> to close the. valve. The upper clutch disc f<6> in moving downwards strikes the rods d<1> and thereby depresses the plate D and moves the feather rods a<11> and the armed clutch c<1> downwards; this releases the upper hand wheel C from the outer sleeve B during its rotary downward movement.

Reverse is established in a synchromesh change-speed gear for a motor car &c. through a two-part idler having one part axially movable relative to the other part. In one form, a two-part reverse idler 164, Fig. 7, is journalled about a support 180, one idler part 166 constantly meshing a countershaft gear (not shown) in turn meshing a gear 36 fast on an output shaft 22. The reverse idler part 166 has an externally splined hub 168 upon which a second reverse idler part 194 may be axially slidden to the full line position shown. The second reverse idler part 194 then meshes external teeth 196 on an axially-slidable ratioestablishing clutch sleeve, when the latter is in its neutral position, and thus establishes reverse. In a modification, Fig. 11 (not shown), the axially-slidable reverse idler has an internal ring of clutch dogs which can be slidden into mesh with clutch dogs upon the other reverse idler, to establish reverse. The two-part reverse idler is described in a four-ratio countershaft gear having aligned input and output shafts with the forward ratios established by selective engagement of balk-ring clutches. Ratio selection &c. is effected by stickers on three parallel rods, retained in desired positions by spring-biased detents and provided with the usual interlock drift pins.

Alternatively, Fig. 11, a resistive layer 27, of, e.g. carbon or foil, is deposited on the drum periphery by printing or evaporation, over an insulating layer 28. In further alternatives, hot air generated by a motor (14), Fig. 6 (not shown), driving the tape or heads may be blown by a fan (15) on the motor shaft on to the drum periphery; or a heater wire (17), Fig. 7 (not shown), may be embedded in the drum; or infra-red lamps (19, 21), Fig. 9 (not shown), may heat the drum periphery and the inner space. The drum temperature may be kept constant by means of thermistors, and the tape drive may be inhibited until the drum has reached a predetermined temperature. Heat generated by drive motors &c. may eventually permit the drum heater to be switched off.
