Title: Improvements in or relating to the separation of intermixed divided materials
IPC: B03B4/02
Filed: 1930-07-14
Abstract: In the cleaning of coal by the method of subjecting a mixture of coal and refuse to the action of mechanical jigging and upward air currents on an air pervious support so as to stratify the elements according to density and then separating the layers, the operation is carried out in two or more stages, in the first of which an upper layer of substantially clean coal is removed and discharged, and the lower layer is passed to the second and subsequent stages for further similar treatment.  The coal product from the second and subsequent stages may be returned to the first stage so that the clean coal is all delivered at one point. Where, in any of the stages, a middlings product is separated it is returned to the head of the same stage.  A modification applicable where the refuse is present in considerable quantities in small sizes, the coal product from the second or subsequent stages may be screened to separate the coal and such small-sized refuse, the coal being returned to the head of the first or any preceding stage.  The invention is described as being carried out on apparatus as described in Specifications 290,276 and 292,495, [both in Class 117, Sifting &c.].  Reference has been directed by the Comptroller to Specifications 297,757, 320,207, [both in Class 117, Sifting &c.], and 352,943.

Title: Improvements in mechanical game apparatus or toys
IPC: A63F9/00
Filed: 1924-09-11
Abstract: 244,168. Stacey, C. F. Sept. 11, 1924. Mechanical toys.-A figure, striker, or recording-part is both propelled and steered or given an erratic course by a substantially rigid meinber vibrated to impart a lateral movement to the figure, said lateral movement being caused to partake also of a forward movement by means connected to the member. As shown, the invention comprises a rod C pivoted at one end to a lever B<1> and carrying at the other a figure C<2>. The weight of the figure C<2> is supported by a wheel C<7> freely rotatable upon a curved portion C<4> of the rod C. The vibration of the lever B<1> about its fulcrum B causes a sideways movement of the figure C<2>, which sideways movement as a result of the curvature of the rod C is caused to partake also of a forward movement. The figure C<2> may thus be caused to move around a track A<10>, and in so doing strike and invert a series of targets D<7> pivoted on a rod D<6>. The track is made in sections and the moving parts may be dismantled for packing purposes. The device may be duplicated for use as a race game apparatus. In modifications, the targets D<7> are replaced by a scale of numbers marked across a section of the track, an index being provided on the rod C to register with such scale. The Provisional Specification describes a modification of the apparatus in which two rods C are connected to one lever B<1>, and also states that the targets may be replaced by detachable balls or hoops, or by obstructions disposed on the track A".

Filed: 1927-08-16
Abstract: 300,601. Forgrove Machinery Co., Ltd., and Grover, F. Aug. 16,1927. Packeting by wrapping-up.-In mechanism for feeding wrappers to wrapping machines in which the wrapping material is fed by pawl or clutch mechanism intermittently operated by a reciprocating part, a tripping mechanism is provided, which is operated by the article to be wrapped and is adapted to disengage the reciprocating part, which would otherwise feed the wrapper, and thus cause the feeding mechanism to miss feeding further wrapping material until a further article to be wrapped has been inserted in the machine. Wrapping material is fed in front of a pocket P by rolls B<1>, B<2> actuated by a pawl B on an arm A which is oscillated by a reciprocating member C. On the reciprocating member C is a block D connected to a crank C<1>. the block being secured to the reciprocating member by a two-armed spring-pressed detent E, Fig. 5, which normally engages in recesses in the parallel rods of the member to compel the block to reciprocate the member but which. if disengaged, allows the member to remain stationary whilst it reciprocates thereon. Associated with the pocket P is an ejector bar N which thrusts a package, when wrapped, out of the pocket and is returned to its rearward position by the insertion of the next article to be wrapped. The bar, in returning to its rearward position, engages an arm fixed to a vertical shaft L which is connected through an arm K, link J and arm H to a spring-controlled rock shaft G. The shaft G carries an arm F<1> provided with a catch F adapted to engage a shoulder E' on the detent E. The movement of the ejector bar N, draws the catch F clear of the shoulder E<1> and the detent locks the block D to the reciprocating member C which actuates the rolls B<1>, B<2> to feed down a length of wrapper. If no article is fed to the pocket P, the ejector bar remains stationary and the spring-pressed arm F<1> engages its catch F with the detent, freeing the block D from the reciprocating member C.

Abstract: 759,569. Electric cigarette lighters. GENERAL MOTORS CORPORATION. July 29, 1954 [Aug. 20, 1953], No. 22199/54. Class 75(3). An electrical cigarette lighter has an igniter removably and movably mounted in a support housing so that electrical contact can be effected between a cup-shaped igniter contact member containing and extending forwardly of, and electrically connected to, a heater and a fixed supply contact or contacts carried by the housing. The igniter is carried in a support sleeve 10 clamped in position on a plate 14, such as a vehicle instrument panel, by an outer sleeve 16 in screw-threaded engagement with the sleeve 10 at 18. The igniter is held in position in the sleeve 10 by tongues 49, formed on the sleeve 10, engaging a flange 47 on the igniter. The forward end of a plastic plug 38 is recessed and carries a sleeve 52 enlarged at 52a to slidably engage the sleeve 10. A stud 60 screwed into the plug 38 carries a metal washer 70, preferably of stainless steel, against which is pressed a metal contact member 72 having radial arms which contact the sleeve 52 and are bent at 140 so as to touch a metallic mass 144. An insulating washer 74 is placed between the member 70 and the end of a cup member 64 the whole being clamped together by a metal flange 80 bearing against two insulating washers 76, 78. The forward end of the stud 60 is tapered and slotted to receive one end of the heater coil 90 the other end of which is welded or otherwise attached to the cup 64. An insulating washer 92, formed with air holes 93 near its periphery, is inserted between the coil 90 and the flange 80. To place the heater coil 90 in circuit the igniter is pressed into the sleeve 10 so that a bead 94 formed on the cup 64 engages a plurality of bimetallic fingers 105 to complete a circuit through a stud 102, fingers 105, member 64, coil 90, stud 60 and washer 72 to earth through sleeve 10. When the coil 90 reaches a predetermined temperature the fingers 105 bend inwardly to release the member 64 which is moved rearwardly by a spring 132 pressing a sleeve 130 against the sleeve 52a. Should the heater coil 90 require to be re-energised while the bi-metallic fingers 105 are still hot the igniter is pressed into the sleeve 10 until a circuit is completed through the cup 64 engaging a metal washer 108. The sleeve 130 has a shoulder 136 which engages an insulating washer 110 on removal of the igniter. Cooling air enters the housing through openings 150 in the sleeve 10, slots 56 in the sleeve 52a and openings 152 in the sleeve 130. The igniter is cooled, so as to facilitate handling, by the annular mass 144 of copper or aluminium engaging the whole of the inner surface or part of the inner surface of the sleeve 52.
