Title: Machine tools with cantilever beams
IPC: B23Q11/00
Filed: 1964-02-17
Abstract: 1,039,153. Machine tool details. GIDDINGS & LEWIS MACHINE TOOL CO. Feb. 17, 1964 [Feb. 20, 1963], No. 6516/64. Headings B3B and B3T. A sliding cantilever supporting beam 30 for the tool of a horizontal boring, drilling and milling machine, or for the ram of a planing or shaping machine, has an anti-sag means which provides a varying upward force to the outer end of the beam to counteract the deflection. A horizontal drilling boring and milling machine, comprises a bed 12, a column 16 slidable on the bed, a head stock 18 slidable on the column, and a tool spindle 26 carried by beam 30. The anti-sag means, counteracts the deflections due to the weight of beam 30, the weight of a tool or attachment mounted at its outer end, and to misalignment of parts of the machine tool. Beam 30 is formed by plates 34-37, and has a sliding fit in the headstock 18, the fit being adjustable by tapered gibs 40. Spindle 26 is fed by a screw and nut 41, 45, Fig. 3 (not shown), and beam 30 is fed by a screw and nut 43, 47. A lever 53 is disposed in beam 30 and is in contact with the latter in three spaced vertical planes I-III. Beam 30 has a pivoted follower 70, and a fixed follower 62, secured thereto, the rollers 76, 85, of which co-operate with a cam 90 so that a downward force can be applied at plane III to lever 53, which varies according to the overhang of the beam, so that the lever pivots at 135 and produces an upward force at the outer end of the beam at plane I. Cam 90 is constructed in two parts, the base 91 which is fixed to the head stock, and a tapered upper part 104 which is slidable in a channel 99 formed in base 91. Bar 104 is adjusted relative to base 91 by a screw 106, a scale 109 being provided. Notches 110-114 are provided in the bar to carry blocks 116-120 having tapers which vary and engage pins 100. The loads due to tools &c. are compensated for by a manually actuated cam-shaft 156 mounted at plane I, the cams on the shaft being of polygonal form each flat of which is designed to compensate for the weight of a different tool. In operation, cam bar 104 is set relatively to base 91, to give a predetermined slope. The beam is extended to the left, and roller 70 rides up the cam and presses follower 70 against lever 53 at 83. If the compensation is found to be incorrect due to misalignment of the machine parts, screw 106 is adjusted to vary the relative position of bar 104, and base 91 to change the cam slope.

Title: Improvements in or relating to slotting mechanism
IPC: B23D3/02
Filed: 1956-03-07
Abstract: 860,599. Planing. VICTORIA MACHINE TOOL CO. Ltd., FRYE, J., and GRONAU, H. June 3, 1957 [March 7, 1956], No. 7150/56. Class 83 (3). A slotting-mechanism comprises a reciprocable driving-slide 4 and a rotatable tool-holder 2, the slide carrying the tool-holder with it for the first part of the cut and then causing the tool-holder to be rotated about a stationary axis to make an arcuate cut and swing the tool away from the work. As applied to slotting a punch (not shown), the mechanism, in the form of an attachment, is secured to the vertical column 27, Fig. 2, of a horizontal milling- machine by screw-operated jaws 29, and is driven by an adaptor in the socket of the milling-spindle connected to a driver 23 carrying a crank-pin 24. Clamping-bolts in a circular T-slot 33 permit angular adjustment of the attachment. A connecting-rod 25 connects the pin 24 to a pin 26 on the slide 4, which carries a slide 6 linked thereto by a crank 3, 12, 13, Fig. 4, at each side of the tool-holder. The journals 3 of the cranks are keyed to the tool-holder and bear in lugs 8 at the end of the slide 6, while the pins 13 connected to the journals by webs 12, bear in slides 10 slidable transversely of the cranks in slideways in a member 7 attached to the slide 4 and arranged to bridge the slide 6. Operation.-With the slide 4 at the top of its stroke, the tool 1 is horizontal, with the toolholder or the tool bearing against a plate 20 on the bridge 7. The tool occupies this setting during most of the down-stroke, until a stop 21 on the slide 6 and projecting through an opening in the slide 4, contacts a surface 22 on the stationary casing 5 of the attachment and arrests movement of the slide 6. Thus further downward movement of the slide 4 causes rotation of the cranks 3, 12, 13, and of the toolholder about the axis of the journals 3, and swings the tool downwardly. The tool remains in this attitude during the upward stroke due to friction, until arrested by .contact between a spring-loaded plunger 14 on the slide 6 and projecting through a slot 19 in the slide 4, and a stop-plate 16 in the casing 5. Further upward movement of the slide 4 to the top of its stroke rotates the tool to the horizontal and, upon contact between a pin 15 supporting the plunger 14 and the bottom 18 of the slot 19, again moves the slide and further compresses the spring 17 loading the plunger. For slotting without a rocking withdrawal, Fig. 10, a hole 38 in the slide 6 is aligned with coaxial holes 36, 37 in the slide 4 and bridge 7, and a tool-carrier 39, with a flange 39a, inserted in the holes to lock the slides together. A tool 41 in a tool-slot 40 is secured against a washer 42 by a screw 43. The eccentric stop 21 is rotated by a knob 45 to an inoperative position.

Title: Improvements in or relating to the manufacture of melamine
Filed: 1943-05-05
Abstract: <PICT:0568015/IV/1> In the manufacture of melamine by heating cyanamide on dicyandiamide in an autoclave in a solvent comprising liquid ammonia, separating the melamine from the mother liquor and stripping and recovering the solvent for re-use, a strong alkali is added to the mother liquor to free it from combined carbon dioxide, with the advantage, when a steel autoclave is used, that the content of iron in the product and in the solvent is substantially reduced. Advantageously, the solvent contains a non-aqueous diluent, e.g. a lower aliphatic alcohol and the contents of the autoclave are discharged into water or an aqueous medium, to which, after separation of the melamine, the strong alkali is added.  In an example, dicyandiamide is dissolved in a mixture of methanol and liquid ammonia delivered from a storage tank 1 into a tank 2 and the mixture is passed into the alloy steel autoclave 3 which is heated for 1-4 hours at 160-200 DEG  C. The resulting slurry is blown into the quenching tank 4 containing water to remove basic impurities of the type of guanidine, biguamide and guanyl urea.  The quenching water contains a small amount of an organic hydroxy compound, e.g. glycerol or mannitol, added to retain the iron impurity in solution. This solution is cooled to reduce excessive loss of melamine while retaining any unconverted dicyandiamide in solution, and is then filtered in the press 5 from which the melamine is withdrawn through a drier 7 and from which the mother liquor, after addition thereto in a tank 8 of an excess of sodium or potassium hydroxide, milk of lime or other strong alkali, is passed through the steam-heated stripping column 9 and the alcohol and ammonia vapours are condensed in the condenser 12, returned to the storage tank 1.  Specification 554,262 is referred to.

Abstract: 541,064. Transmission gearing for motorvehicles HARDY, SPICER & CO., Ltd., and HARDY, J. L. April 8, 1940, No. 7227/41. Divided out of 541,044, [Group XXXI]. [Class 80 (ii)] In a motor vehicle which can be driven from a differential gear the wheel axles 28 have splined ends 33 on which are secured sleeve devices forming the inner parts of roller-type free-wheel clutches, the outer parts of which are constituted by portions of the wheel hubs. In the construction shown, providing automatically reversible free wheeling, a sleeve 37 splined to each axle 28 is loosely surrounded and engaged by tapered-sectioned splines 41 on a split ring 40. Caged clutch rollers 35 are located between the perimeter of the ring 40 and the bore formed in the portion 36 of the wheel hub. When the axles 28 are driving the interaction of the taper splines 41 causes the ring 40 to expand and jam the rollers 35 to drive the wheels. The ring 40 has sufficient inward resiliency to permit the rollers 35 to have a running fit if overrunning is to occur. The invention is particularly applicable to vehicles having at least one pair of wheels always differentially driven, and, in addition, at least another pair which are differentially driven for the first forward speed or for the reverse drive. Specification 541.044 is referred to.
