Filed: 1937-08-05
Abstract: 497,609. Plugging well pipes. TRIGGS, W. W. (Hydril Co.) Aug. 5, 1937, No. 21636. [Class 85] A well pipe plug adapted to be lowered into the pipe by suspension means comprises sleeve and mandrel sections relatively movable vertically, the mandrel section containing a fluid passage, radially expansible pipe engaging means depending from and movable vertically with the sleeve section for expanding and contracting movement, and a valve controlling fluid flow through the mandrel passage, the valve being opened and closed by relative movement between said sections. The body 10 is connected through a swivel joint and sub 12 to a drill pipe string. A tubular mandrel 16 is movable vertically within the body and slidably supports a rubber packer 44 with looped reinforcing cables 45, and a wedge sleeve 38 for expanding slips 30 guided therein and suspended through links 31 from the body closure 28 ; the links 31 are loose on their pivots to protect the latter against thrusts. A conical packer expander 52 is threaded to the mandrel and to a hollow member 54 containing a spring- pressed valve 59 and provided with leaf springs 22 engaging the casing 15 to hold mandrel 16 against rotation. An inner pipe 19 holds the valve 59 open when in its lowest position and is keyed at 68 to the mandrel and at 76 to a guide 73 slidably keyed to the body 10; the pipe 19 has a shoulder 70 limiting vertical movement relative to the mandrel and has a threaded connection at 81 with the sub 12. Rotation of the drill string raises the pipe 19 so as first to permit the valve 59 to close and then, through shoulder 70, to raise the mandrel 16 to cause the slips 30 to grip the casing and finally to expand the packer; reverse rotation of the drill string lowers the pipe 19 and first opens valve 59, then moves expander 52 to permit contraction of the packer, and finally, through ring 42, moves sleeve 38 to slipreleasing position.

Title: Sewing machines and product made thereby
IPC: D05B57/00
Filed: 1935-07-30
Abstract: 452,681. Sewing-machines. POLLACK & CO., Inc., M., 15, West 37th Street, New York, U.S.A. July 30, 1935, No. 21664. Convention date, June 20. [Class 112] The needle or needles of a laterallyvibrating needle machine are mounted on the needle bar with a limited freedom to swing in the direction of feed if a deflecting surface such as a ridge containing an elastic thread, is encountered. This enables the needle to avoid cutting through the thread. In the form shown, two needles 29 are mounted on complemental holders 35 pivoted to the base 34 of the needle bar 20 by pins 37 about which the needle holders have a limited amount of swing determined by adjustable screw stops 40, Figs. 3 and 4. The pull of the thread keeps the needle in its forwardly inclined position. The needle bar 20 is given its jogging movements about a pivot 17 by an arm 18, these movements being limited by a slot 19 working on a pin. To ensure that the needle is always brought to the correct position for the rotary hook beak 60 to enter the needle loop, the hook member 26 has a flared guide 59 narrowing to a needle-positioning neck 57 in front of the hook beak, Fig. 13. In joining elastic fabrics by the seam 69 and strip 70, Fig. 18, elastic threads severed by the seams 71 are held down by the adjacent seams 66 sewed by the machine described, the needles 29 avoiding the elastic threads as shown in Fig. 20. The needle in the dotted position is deflected by the ridge to the position shown in full lines, to avoid severing the elastic thread 42. The needle point is tapered more steeply at one side 55 than the other 56. In a modification, the needles are mounted rigidly in the holder and the lower half of the needle-bar is pivoted to supply the necessary freedom of movement. In this case, the needles cannot move independently as in the first form.

Title: Improvements in or relating to automatic electric circuit breakers
IPC: H01H83/20
Filed: 1943-12-31
Abstract: 569,971. Automatic circuit-breakers. SHEPHERD, G. R. (Westinghouse Electric International Co.). Dec. 31, 1943, No. 21936. [Class 38 (v)] A circuit-breaker preferably of the " deadfront " type, has a trip mechanism comprising an electromagnetic and a thermal trip means independently operable to actuate an axially-rotatable trip bar to cause opening of the breaker with predetermined circuit-conditions, and means for controlling the operation of the trip mechanism independently of the circuit-conditions. The base 1 has knife contacts 10, 11 for removably engaging clips 12, 13 on a panel 14, the contact 10 being recessed to engage a pin 22 on the clip 12 to ensure separation at 11, 13 first. Movable contact 5 co-operates with contact 3 in a magnetic-plate arc-chute and is carried by an arm 4 pivoted at 23 and movable, together with the arms 4 of other poles, manually on and off, by means of a spring-toggle arrangement, provided a cradle 33, pivoted at 34, is retained by a latch 80, Fig 4. A unitary trip structure comprises a base 46 accommodating a bimetal and an electromagnetic, trip for each pole. The latch 80 is slot pivoted to a pin 73, and biased clockwise, Fig. 5, by a spring 79 to oppose the thrust of cradle 33. The tail 76 is held by a part 77 of a common trip bar 66 which is biased by spring 68 clockwise about its pivot in brackets 87, Fig. 4, and movable against this bias by a series bimetal strip 49 or trip magnet. The trip coil comprises a copper strip 64 and highresistance strip 65, which serves also as heater for the bimetal, encircling the centre limb of the E-shaped coil 57 riveted at 62 to the base 46. The armature 58 is urged about pivot 59 by a compression spring 61 so as to bear on a setting- member 84 pivoted on screw 85, Fig. 5. To ensure tripping of the breaker when being removed from panel 14, the trip bar 66 is engagable by the widened part of a push rod 87 which projects through a hole in the base and is urged to bear normally on the panel surface by a spring 88, resetting of the trip mechanism being impossible while the breaker is detached. In a modification, Fig. 2 (not shown), the back of the panel supports a remote control electromagnet, the armature of which operates a trip rod similar to rod 87 of Fig. 1 and prevents resetting so long as it is engaged. In a further form, Fig. 3 (not shown), the trip bar 66 is locked by depression of a push-button as, for example, in starting a motor. In further forms, Figs. 6, 7 (not shown), the electromagnet trip armature of each or all the poles can be locked against operation by a separate or common push-button, the thermal release being free to operate the trip bar in both cases. In all these forms, the push-button may be latched in the operative position to prevent resetting.
