Title: Improvements relating to drilling machines
IPC: B23Q1/00
Filed: 1931-10-08
Abstract: 386,055. Speed control for drilling- machines. ASQUITH, Ltd., W., Highroad Well Works, and FEATHER, G., Wells by House, Highroad Well, both in Halifax, Yorkshire. Oct. 8, 1931, No. 27935. [Class 83 (iii).] An indicator for a drilling-machine for enabling an operator to see the correct speed for drills of different sizes and also the cutting speed comprises an arm a fixed to the changespeed shaft B of the spindle-driving gearing and terminating in an aperture A which moves over a drum C which is rotatable about the axis of shaft B by worm gearing c<3>. The surface of the drum is marked with drill sizes arranged in geometrical progression to conform with thirtysix spindle speeds, these speeds being obtained by rotary and longitudinal movements of the control shaft B. These speeds are indicated on a fixed plate e. The drum is also marked with cutting speeds which are observable through an aperture e<2>. In operation, if for instance a cutting speed of 60 feet per minute is to be used with a drill of 3<5>/16" diameter the drum is rotated until the 60 is observed in the aperture e<2> and the shaft B is moved until the indicator A is over the 3<5>/16" mark on the drum. This automatically selects the required spindle speed which by reference to the table e is seen to be 68 revolutions per minute.

Title: Apparatus for stretching thermoplastic films with beaded edges
IPC: B29C55/16
Filed: 1960-08-15
Abstract: 959,449. Film-stretching apparatus. GEVAERT PHOTO-PRODUCTEN N.V. Aug. 15, 1960 [Aug. 14, 1959], No. 28159/60. Heading B5B. Apparatus for stretching continuously extruded organic thermoplastic film web having beaded or thickened edges comprises a roll 1 (Fig. 1), on which the hot film is received from the slot-shaped extrusion orifice of an extruded head and on which roll and the following rolls 2 and 3 the film is cooled down to a suitable temperature for the subsequent drawing of the film. The peripheral speeds of rolls 1 to 3 are the same and are equal to or greater than the extrusion speed. The film web after leaving roll 3 engages at its beaded edges the guide members of the frames 4 and 5 (Fig. 2), which cause the film to stretch transversely because the guide members diverge in the direction of travel of the film. The transverse stretch ratio may be adjusted by adjusting the angle between the guide members and when only longitudinal stretching is required as, for example, in the manufacture of magnetic recording tape, the guide members are adjusted to be parallel with one another, their function then being to prevent transverse shrinkage of the film during the longitudinal stretching operation. The guide members of the frames 4 and 5 each consist of two superimposed metal walls defining between them a longitudinal slot which is located in the plane of travel of the film and which is adapted to receive the films, and two strips 9 and 9<SP>1</SP> (Fig. 6), of a solid material having a low coefficient of friction such as graphite or polytetrafluoroethylene secured in longitudinal recesses in the outer surfaces of the walls adjacent to the slot. After leaving the guide members the film is conveyed to the draw rolls 6 to 8 which are driven at a peripheral speed greater than that of the feed rolls 1 to 3. The beaded edges of the film are preferably cut away before the film reaches the draw rolls. The film edges may be maintained at a temperature higher than that of the remainder of the film by infra-red radiation units positioned parallel to the film edges, as shown in Fig. 5. Specifications 746,386, 883,312, 916,660 and 959,450 are referred to.

Filed: 1927-10-25
Abstract: 294,032. Hansen, H. C. Oct. 25, 1927. Coin action, mechanical-connection; testing coins; returning coin.-A coin-freed vending machine is provided with a mechanism so that the machine can be actuated only by the insertion of coins of a predetermined size provided with a rim on both sides along their periphery. A slide 1 is connected to the drawer or opening member of the machine and a slide 20 to the locking-mechanism. A preliminary movement of the opening member causes a coin 19 inserted through a shoot 18 to be pressed against an arm 22 extending from an upright 21 on the slide 20 to move this slide and release the opening member for a full delivery movement. The coin drops between two upright plates 3 on the slide 1 and rests on two rollers 15, 16. The plates 3 have blocks 4 in which are pivoted vertical shafts 5 carrying heads 6 provided with beaks 7 and tails 8. The beaks are normally held away from the coin by a spring 11 holding the inner ends of arms 10 on the lowers ends of the shafts 5 against stops 13. When the slide 1 is moved towards the slide 20, the spring 11 causes the beaks 7 to move inwards nearly into contact with the coin surfaces. The beaks then engage the projecting rims on the coin and press it against the arm 22. Screw stops 9 for the tails 8 limit the inward movement of the beaks. When the outer ends of the arms 10 meet stops 24, the beaks are moved away from the coin which, the slide 20 receiving a quick forward movement, rolls off the rollers 15, 16 to a moneybox. If the coin has not got projecting rims it is pushed back by the arm 22, rolls down an incline 17, and drops through an opening 25 behind the slide 1 to be returned.

Abstract: 651,230. Making springs. GENERAL MOTORS CORPORATION. Nov. 9, 1948, No. 29070. Convention date, Nov. 13, 1947. [Classes 83 (ii) and 83 (iv)] [Also in Group XXXII] Altering physical structure.-In the manufacture of a single-leaf spring 10, having a substantially uniform width and a variable thickness to effect substantially uniform operating stresses at all sections, the tension-side and adjacent corners of the spring are shot peened, subsequent to a hardening and tempering operation and while the spring is stressed near to its yield point. The contour of the upper face of the spring is of double parabolic form (Figs. 5 and 6, not shown). The spring is heattreated to a temperature above AC3 and is then mounted on a quench form (Fig. 3, not shown) and quenched with oil or equivalent means to harden it. The hardened spring is then removed from the quench form and tempered without restraint. The spring, which after hardening and tempering is curved when free, is clamped to a fixture 20 of a shot peening machine under a stress of between 125,000 and 200,000 pounds per square inch with the tension side exposed to shot peening nozzles 24. The nozzles may be at an angle of 45 degrees to the vertical and the peening may be effected in one or more passes through the machine. After shot peening, the spring is pre-set (Fig. 7, not shown) by deflecting it in the direction of service loading, without heat, by an amount which exceeds the service deflection by between ten and thirty per cent. After pre-setting, the spring is preferably given anti-corrosion treatment with, for example, a phosphate or paint. The shot peening may be repeated after pre-setting with the spring in its free or stressed condition. When applied to a vehicle suspension (Fig. 10, not shown), the spring is preferably clamped to the vehicle axle, a flexible liner to which the spring may be cemented being interposed between the clamp and spring.
