Title: Improvements in or relating to methods of and apparatus suitable for use in making slip-lasted shoes
IPC: A43D3/02
Filed: 1947-10-03
Abstract: 628,703. Making slip-lasted footwear. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Oct. 3, 1947, No. 26626. [Class 17 (i)] In making slip-lasted shoes a form, comprising fore and heel parts connected to a common member and of appropriate size on the shoe supporting faces for the shoe concerned but with the girth of the fore and heel parts less than that of a normal last, is used in place of the usual shaping last, until after the outsole has been attached, in order to facilitate positioning the insole on the last bottom. This form is in fore and heel parts 20, 22 respectively, of light metal with parts 26, 28 extending heightwise from the base in a groove 30 in which a steel plate 32 is secured by pins 34, 36, 38, Figs. 1, 3. The rear part 22 can be turned counterclockwise about the pin 38 to allow easy insertion into the shoe upper but is normally held in position by a spring 48 acting on a plunger 46, in the plate 32, which engages a lip 50 of the heel part 22. A spring 44 and a plunger 42 normally hold the parts 20, 22 open at the breast line so that the form can be foreshortened by half a shoe size if desired. Slots 52, 54 allow the form to be mounted on pins of a stand on which it can be locked by a spring catch engaging a projection 56. The toe portion is made about the usual last size to allow the use of the form on shoes open at the toe end. In a modification, the form is cast from light-weight metal but has dimensions smaller than the usual last except at the sole. The stand is also modified to have slots to receive pins inserted in the cast form and a spring catch to lock the form in position on the stand. A method of making a slip-lasted shoe consists of inserting the shoe entering form into the unlasted shoe and positioning the insole on the form bottom so that the insole and upper attaching seam is aligned exactly with the edge of the form bottom, an operation which is facilitated by the reduced girth of the form. The form is then mounted on the stand and a platform sole is placed in position and attached by cement and pressure in a suitable press. The form is removed from the stand and the platform wrapper is tensioned and laid over the bottom of the platform. It is then replaced on the stand and an outsole is similarly attached. The form is then withdrawn and a heel attached in a usual manner and after this a normal last may be inserted if it is desired to give a better finished shape. Specification 598,216 is referred to.

Title: Improvements in or relating to a temperature responsive switch
IPC: H01H37/54
Filed: 1964-06-26
Abstract: 1,060,626. Thermal switches. VITRAMON Inc. June 26, 1964 [June 28, 1963], No. 26669/64. Heading H2B. A spring blade contact is biased towards a fixed contact but is normally restrained in the open circuit condition by bimetallic strip engaging the end of the spring blade. Upon rise in temperature the spring blade is allowed to engage the fixed contact and the bimetallic strip moves on to disengage the end of the spring blade (until it cools down) thereby avoiding any interference with the contact pressure by vibration of the strip. In a first embodiment (Fig. 1, not shown) the bimetallic strip is fixed at one end with its other end curled over to engage the tip of the spring blade and is given a greater bias away from the fixed contact than the bias of the blade towards the fixed contact. In a second embodiment (Fig. 2, not shown) the bimetallic strip is bowed between opposite sides of the switch housing so as to move with a snap action and a small bracket-like member is attached thereto to restrain the end of the contact blade in one condition of bowing, but to move clear of the end in the snapped-over condition.

Title: Improvements in motor-control systems for electric lifts and the like
IPC: B66B1/50
Filed: 1920-09-23
Abstract: 171,846. Waygood-Otis, Ltd., (Otis Elevator Co.). Sept. 23, 1920. Systems with high and low voltage machines. -In a motor control system for electric lifts the hoisting motor is used with high voltage current for normal work and with low voltage current for operating at a definite slow speed in order that the cage may be brought or returned to exact landing position. The change from the high to the low voltage supply is made automatically whenever it is necessary to level the cage, and the low voltage supply is cut off automatically when the desired position is reached. The invention is shown in the Figure as applied to a push-button lift system. The low voltage current is taken from the brushes 9, 9' of a rotary converter G, the brushes 10, 10<1> of which are connected to the high voltage mains +, -. Cams 12, 13 are mounted in the well at each landing and actuate switches 12<1>, 13<1> on the cage C, controlling connections between the hoisting motor M and converter G. If the cage is descending and approaching the landing L, the switch 13<1> closes and completes a circuit which includes the winding 11 of a change-over switch A. The raising of the switch A, disconnects the reversing switch D from the high voltage mains +, - and connects it to the converter G by a circuit including a resistance 35. If at the time of change the motor M is generating in excess of the converter G, a dynamic braking action is produced which slows the motor M until its speed is that of the converter G. When this occurs, the arm a of the accelerating magnet F opens and closes the contacts 42 which short circuit the resistance 35. When the cage reaches the landing L' the switch 13<1> rides off the cam 13 and being opened by a spring causes the switch A to fa'l and the switch D to open. The opening of the circuits controlled by these switches, cuts off the supply of current to the motor M and causes the application of the brake 1. If the cage over-runs the landing, the switch 12<1> is closed by the cam 12 and effects the closing of the reversing switch U and the raising of the changeover switch A. The actuation of these switches puts the converter G into operation and causes the motor M to be operated to return the cage to the landing. The application of the invention to a lift system in which the hoisting motor is controlled by a switch on the cage is also described.

Abstract: 758,304. Valves. ATWOOD & MORRILL CO. Sept. 20, 1954 [July 22, 1954), No. 27104/54. Class 135. In a rotary conical plug valve of the non- lubricated type complementary cam means rotatable with valve operating means and the valve plug respectively when locked together by latch means cause rotation of the valve plug unaccompanied by axial movement and when unlocked cause axial movement of the valve plug unaccompanied by rotation. As shown, a valve plug 12, Fig. 1, is secured to members 21, 22 having spaced parallel cam surfaces 25, 26 engageable with a cam member 28 carried by an operating spindle 30. The member 22 is formed with a recess 35, Fig. 2, engageable with a latch 36 secured to the spindle 30 by a collar 44 and loaded by a spring 46, so that an upper arm 45 of the latch is urged into engagement with the inner surface 48 of a bonnet 20 having a cut-out portion closed by a shield 52. The member 21 carries a stop pin 54, Fig. 4, which rides over a surface 62 formed on a locking member 58 secured to the valve yoke 10 and engages gaps formed between stops 55, 56 on the yoke and abutments 60, 61 on the member 58. On anticlockwise rotation of the spindle 30 from the position shown in which the arm 45 presses against the surface 48, the cam member 28 rotates to raise the members 21, 22 and with them the valve plug 12 and the stop pin 54 until the latch is opposite the shield 52 and the stop pin 54 free of the gap between the stop 56 and the abutment 61. The latch is then urged by its spring into engagement with the recess 35 and rotation of the spindle during the next 90 degrees rotates the plug 12 into its open position. On further anticlockwise rotation of the spindle 30, the latch rides up the surface 50 to disengage the latch 36 whilst the pin 54 positions itself opposite the gap between the stop 55 and the abutment 60. As the rotation continues the pin 54 and members 21, 22 are lowered and the plug 12 is lowered into seating engagement with its valve body 1.
