Title: Improved process of and apparatus for making wheels
IPC: B21D53/26
Filed: 1922-03-29
Abstract: 198,842. White, A. E., (Bethlehem Steel Co.). March 29, 1922. Wheels.-In the process of forming wheels from flanged metal bars, such as A, Fig. 1, the web of the bar is apertured as at 4, Fig. 3, at equal intervals to form the part outline of the spokes, then progessively cut as by suitable punches 11, Fig. 7, to complete the outline at the spokes and to divide the bar into two wheel forming blanks, each of which is then treated to bend the spokes alternately to opposite sides, and to form the blank into a circle with the splayed spokes enclosing a spacing member at the centre. The apparatus for forming the apertures 4 consists of punches, and the edges of the apertures are rounded off by chamfering punches. The punches 11 for severing the blank and completing the spoke-forming operation may be of any suitable shape, pilot pieces 10 being provided for positioning the blank after each feed movement. The spokes are splayed in a die, Fig. 10, comprising a die-block 14 having an annular projection 15 and raised portions 16 alternating with depressions. The die 18 is formed of a shape complementary to the die-block. The operation for bending the blank into a circle consists of two stages, in the first of which the ends are bent into arcs of radius equal to that of the completed circle. This operation is performed in apparatus comprising a two part die-block having inward projections 24, Figs. 15 and 16, forming a support for the flange of the bar, and cut away at their ends so as not to interfere with the spokes. The ends of the. die-block and of the forming die are curved to the required radius. The partially bent blank is then transferred to a circular two-part die block 30, Figs. 17 and 19, mounted on a shaft 32 with a spoke spacing member 33. The forming dies consist of two cam-shaped members 34 pivoted at 35 to the press 36, and provided with rollers 39, 39'. Link rods 43 are pivoted to the members 34 and have sliding movement in relation to the press-frame 37 limited by collars 45, 46. In the downward movement of the die, the shoulders 40, 41 remain in engagement till the rods have reached their limit of movement after which further movement of the press causes the rods to swing the members 34 about their pivots 35.

Title: Improvements in or relating to the synchronisation of sound records with moving picture films
IPC: G03B31/00
Filed: 1929-03-25
Abstract: 335,882. Green, H., and Celebritone, Ltd. March 25, 1929. Synchronous movements.-A camera or projector and a sound recording or reproducing apparatus are driven by separate motors A, B respectively, each of which drives a multi-contact rotary contact maker C, D. The corresponding contacts 1<c> - - 24<c>, and 1<d> - - - 24<d> are electrically connected. The adjacent contacts of at least one of the rotary contact makers are interconnected by equal resistances f. Rotary brushes C<1>, D<1>, revolve over the rings of contacts and are connected to the circuit of the controlled motor B, a voltmeter V being placed across them. The speed'of the controlling motor A is regulated by any electrical or mechanical speed governor. A manually variable resistance R is included in the circuit of the-controlled motor B and is adjusted so that the phase displacement between the brushes when the motors are in synchronism is preferably about 45‹. If the motor B is of the series type the brush D<1> will be in advance of the brush C. Should the speed of the motor B increase the increase in the angular displacement of the brush D<1> throws, more resistance in the motor circuit and the motor B is slowed down, and vice versa. Should the motor B be shunt wound the brush D' will lag behind the brush C<1> so that as the motor B increases in speed the resistance of the field circuit is reduced. Should the gramophone and kinematograph get out of phase, as by the stylus jumping a groove on the record, correction may be made by varying the resistance R so as to change the angular relationship of the brushes C<1>, D<1>. One of the Provisional Specifications describes means for synchronizing two motors each of which has its own speed-regulating means. Each of the two motors drive an electric generator, the outputs from the two generators being caused to act in opposition upon a polarized relay. This is operated in one or other direction by the outof-balance current to cause short-circuiting of resistance in the field of one or other motor to re-estahtish synchronism. The synchronism means described in the first paragraph may also be used to correct for slight changes in synchronism.

Title: Method and machine for the straightening and bundling of cattle and horse hairs
IPC: D02G3/14
Filed: 1963-03-11
Abstract: In a machine for straightening, bundling or binding animal hairs in preparation for heat-setting to remove curl or crinkle therein, each bundle of hair is subjected to pressure directed radially and around the periphery thereof, is drawn axially through the means whereby such pressure is applied so as to tension and straighten the individual hairs, and a thread or wire is progressively wound around the bundle to secure the hair in straightened condition.  In operation, the jaws 6, Fig. 3 (not shown), of a pressure device A, Fig. 1 (not shown), are opened and then closed, by moving a handle 7 to rotate a slide (5) operating ring 3, to receive and then grip a bundle of hairs passed therethrough, and the leading end of the bundle is tightly clamped between manually operated jaws 23 of an axially displaceable device B which at this stage is in its extreme right hand position.  Driving motor C is started and clutch 39 is momentarily held disengaged by pressure on pedal 48 (during which time several turns of thread are wound, from a rotatably driven bobbin 10, around the end of the bundle).  Clutch 39 is engaged to start rotation of screw-threaded rod 32 and move carriage 30 therealong, to the left, so as first to produce a gradually increasing tension on the hairs and then to draw them through the jaws 6: the thread from bobbin 10 continues to be wound in helical form around the bundle.  On completion of the operation, the carriage 30 engages a limit stop 45, clutch 39 is disengaged, motor C is (automatically) stopped, jaws 23 are opened and the thread end cut to release the bundle.  Motor C is run in reverse direction and, through a high speed belt and pulley 34, 36, (or chain and sprocket) drive, returns carriage 30 to limit stop 46 whereat the machine is prepared for the next operative cycle.  The pitch of the thread binding and the screw-threaded rod 32 may correspond.

Title: Manufacture of artificial threads and other products from cellulose compounds
IPC: D01F2/28
Filed: 1929-03-25
Abstract: 335,906. Lilienfeld, L. March 25, 1929. Yarns &c., treating with liquids.-Sizings for yarns and other materials are made by incorporating substances capable of providing one or more substituted or non-substituted alkyl, oxyalkyl or hydroxyalkyl radicals with a cellulose derivative containing one or more CSS-groups, and the product obtained is acted upon by an agent having a coagulating and plasticizing effect, or by a coagulating agent and then by a plasticizing agent. The cellulose derivative may be viscose and the added substances specified are halogen derivatives of di- or polyvalent alcohols. The viscose may be prepared from sulphite woodpulp or linters, or from cellulose which has been pretreated with acids, and it may be used in the unripened state or have undergone ripening at any stage of its manufacture. Instead of viscose, a cellulose-xantho-fatty acid or cellulose dixanthate may be employed. 'The added substance may be a halogen derivative of a di- or polyvalent alcohol or of an ester, ether or anhydride of such alcohol, and the reaction with the viscose may be carried out with or without gentle heating. The plasticizing agent is preferably strong sulphuric acid of at least 35 per cent strength and it may be mixed with other acids such as hydrochloric, nitric, phosphoric, boric, acetic, formic, lactic, or oxalic acid, or with salts such as sulphates, bisulphates, sulphites, and nitrites, or aniline salts, glycerine, sugar and glucose. The sulphuric acid may be replaced by other strong acids such as hydrochloric, nitric, phosphoric, or arsenic acid or strong zinc chloride solution. The product of viscose and the halogen derivative of a polyvalent alcohol may be first coagulated in solutions of ammonium sulphate, or sodium bisulphate and dilute sulphuric acid, or sulphates of sodium, ammonium, and zinc, with dilute sulphuric acid and glucose, and then treated with a plasticizing agent. The temperature of the plasticizing bath may be above or below room temperature, and the time of treatment is such that the material is not appreciably attacked. 'The substance added to the viscose may be a mono- or di-chlorohydrine, ethylene chlorohydrine, mannite dichlorohydrine, epichlorhydrin, glycerine-a-monochlorohydrine, propylenechlorohydrine. trimethylene-glycol chlorohydrine, trichlorohydrine, or a chlorohydrine of pinacone, erythritol, penta-erythritol, mannitane, dulcitan, divinylethylene-glycol, phenylpropanol, naphthylpropanol, or 4-methoxynaphthylpropanol.

March 27, 1935, No. 9553. [Classes 78 (ii) and 78 (v)] Electric conductors and other wires are attached to a drum by passing a loop of the wire into the drum through a slot and gripping it between a pivoted member l and the edge r of the slot. The upward movement of the pivoted member l, Fig. 3, is limited by a stop p, and the member may be slotted at s, Fig. 4, to receive the loop. In a modification the gripping member l is formed integral with a rotatable member which is concentric with, and held by friction within, the drum. A shield u prevents the wire from coming into contact with the spring, and this contact also is prevented by making the initial and final coils v, w, Fig. 6, of the spring x closely encircle the spindle. The spring is formed from wire of rectangular section. In a further modification the loop of wire is passed through an aperture y, Fig. 9, in the drum and is engaged by an arm s formed on a rotatable member t mounted concentrically with the drum. The components may be made of phenol-formaldehyde, urea-formaldehyde, or similar compounds known as synthetic resins.
