Patent GB-736788-A (GB)
Title: Improvements in assembling fasteners with washers
IPC: B23P19/08
Filed: 1951-07-05
Abstract: 736,788. Assembling screws and washers. ILLINOIS TOOL WORKS. July 5, 1951 [Aug. 3, 1950], No. 16004/51. Classes 83 (2) and 83 (4). Relates to assembling screws &c. and washers and consists in feeding a strip of inter-connected washers along a path and feeding screws along a plane path that converges with the path of the strip in such manner as to insert the screws successively in the washers. The screws are fed from a hopper and pass by gravity down guide rails 184 provided with a guard rail 192 above the heads. A vertically movable yoke 204 engages the screw heads by a spring 212. If the supply of screws fails the spring no longer supports the yoke which descends, actuating a switch 214 to stop the driving motor. The rails end in a curved extension that delivers the screws through a gap in a guard rail adjacent a toothed wheel 48. Smooth passage from the rails 184 to the spaces between the teeth is ensured by light fingers engaging under opposite sides of the heads. A continuous strip of washers 34 in which adjacent washers are connected by opposed twisted teeth 404, Fig. 17, already weakened by the twisting, is in coiled form, as described in Specification 704,559, and the coil is placed on a drum 32, being supported by a flange. The drum is supported from below in such manner that it can be swung aside from under the wheel 48 to facilitate the loading of a fresh coil of washers. The end of the strip is led up the drum in the form of an open helix and it passes over a supporting roller 274 and under a detector roller 286 on an arm 282. If the strip breaks or runs out, the arm 282 ceases to be supported and actuates a switch 288 controlling the motor similarly to the switch 214. Beyond the roller 286 the strip enters a guide channel 218 that brings the washers along a path conforming to that of the screws and convergent therewith so that the screw shanks gradually enter the washers, being finally fully engaged by a spring 268. Further guides 294 with a spring hold-down 354 conduct the assemblies to indenting rolls 326, Fig. 14, that raise burrs on each side of indentations and render the washers captive during subsequent handling prior to the rolling of the screw threads, which renders the washers finally captive and removes all traces of the burrs and indentations. Guides 358 transfer the assemblies from the indenting rolls to a feed wheel 370, Figs. 4 and 16, from which they are stripped by an adjustable member 396, forming a guide channel with a fixed member 392, the angle of the channel in relation to the wheel 370 being such that the strip is given a sharp bend in the plane of the washers at the moment of stripping and this sudden bend is sufficient to sever the individual assemblies from the strip. Specification 736,780 also is referred to.

Title: Improvements in devices for setting up skittle pins
IPC: A63D5/02
Filed: 1961-05-03
Abstract: 961,556. Skittle alleys. PHILIPS GLOEILAMPENFABRIEKEN N.V. May 3, 1961 [May 3, 1960], No. 16030/61. Heading A6D. A vertically movable table 18 for depositing skittle pins in a predetermined pattern at the end of a bowling alley 1 is fed from an intermittently rotatable distributer 17, Fig. 3, having peripheral pockets 16 which, in turn, receive an inverted pin from a conveyer 34 until a set is complete, the pins collectively being then removed from the pockets by an ejector 35 which tilts them, base first, into shoots 12 for delivery upright, through channels 14, to the table. Balls 5 and skittles 3 which roll or are moved by a mechanicallyoperated sweeper 23 into a pit 2 are fed by a conveyer 26 to spaced bars 28 of a vertical elevator 27 and carried to a horizontal conveyer 29 leading to a device 30 for separating ball and pins, the balls passing through a channel 32 and conveyer 50 to the opposite end of the alley. The pins 3, in turn, travel by way of friction wheel 33 and guide rail 31 to conveyer 34 and are presented to the pockets 16, which are separated by partitions 39. Each pin on entering a pocket actuates a switch 41 through a lever 42 to rotate the distributer and this action continues until all but one of the pockets are occupied, whereupon the first pin engages a switch 47 which cuts out switch 41 and nullifies the action of a pin which may have moved into the remaining pocket. A curved rail 38, interrupted beneath the conveyer, may be associated with the distributer to draw the heads of the pins inwardly and when ejector 35, which has recesses in its upper face, is raised by levers 36, 37 the pins simultaneously tilt outwardly into shoots 12. The ejector 35 may also be interrupted below conveyer 34. Alternatively, the rail 38 may be omitted and the ejector formed with a concave upper surface to move the pin heads inwardly. A rubber band 4 encircles each skittle.

Title: Apparatus and process for heat exchange treatment of fluids
IPC: B01D1/22
Filed: 1956-05-29
Abstract: <PICT:0799618/III/1> <PICT:0799618/III/2> In an apparatus for the heat - exchange treatment of liquids, wherein the liquid, introduced by one or more inlets 40, is caused to rise as an annular film on the wall of the vertical cylindrical chamber 10 by means of centrifugal motion imparted by the vanes 55, the treated liquid is deflected by an obstruction 47 at the top of the chamber into a tangential discharge outlet 60.  The apparatus may be used for the evaporation of liquids, e.g. in concentrating solutions, or for effecting chemical reactions in which case a liquid may be introduced by one inlet and a separate liquid or gas through another, similarly a liquid catalyst or dispersion of catalyst particles in a liquid may be introduced by a separate inlet.  Liquids may be introduced under pressure.  The walls of the chamber are heated by steam or other heating fluid passed through the two heating chambers 17 and 18 formed by the outer cylinder 16, separated by the ring 19, and each having an inlet 20 and an outlet 21.  More heating chambers may be provided and alternatively electrical heating may be used.  The top of each vane 55 is shaped with a short horizontal portion 57 and a downwardly slanting edge 58.  The bottom surface of the plate 46 has a level portion 47 constituting the obstruction and a depending lip 59 which interfits with the slanting edges 58 of the vanes.  The rising liquid is deflected into the spiral or involute channel 44 and thence into the tangential outlet 60.  The lower corners of the vanes 56 may be chamfered.  Vapours leave by exit tube 50 formed with a trap to collect escaping droplets of liquid. High or low pressures may be used if desired, in the case of vacuum evaporation it is not necessary to collect the liquid under vacuum or to pump out the liquid since the combination of the dam and the vanes give sufficient centrifugal force to cause an outward pressure and flow of liquid. Examples are given of the concentration aqueous gelatin and of a dispersion of silver halide in aqueous gelatin.
