Title: Improvements in paint brushes
Inventor: DAW DONALD GEORGE
IPC: A46B15/00
Filed: 1960-02-10
Abstract: 951,759. Paint brushes. AMERICAN FLANGE & MANUFACTURING CO. Inc. Dec. 30, 1960 [Feb. 10, 1960], No. 4656/60. Heading A4K. A paint brush comprises a handle 8, one end of which has apertured wall portions, a ferrule 19 fitting about the said one end with a close sliding fit and having bristles mounted in the front end thereof, and means interlocking the apertured wall portions, the ferrule and the bristles, the means being wholly or partly an adhesive mass. In one embodiment (Figs. 2 to 4) a bridge piece 15 having legs 16 is fitted to one end of a handle 8 by means of spigots 17 engaging apertures 14. When in position the top plate of the bridge extends close to the ends of lugs 13. The bristles 7 are loaded in a ferrule 19, pressed in a cowl 21, and bonded therein by adhesive. When that adhesive has set a further quantity is added to the surface of the set adhesive and a small quantity applied to the rear edge of the cowl 21. The ferrule 19 and cowl 21 are pushed over a wall 10 of the handle until their rear edges engage in a recess 12. The second layer of adhesive is pressed firmly on to the bridge 15 and is squeezed through holes 18 to effect a locking engagement when set. In a second embodiment (Fig. 7) the bridge piece is dispensed with. The lugs 13 are embedded in the second layer 26 of adhesive which passes through apertures 24 effecting, when set, a locking engagement. The handle, ferrule, and cowl and bridge, if used, may be of nylon or other plastic. Alternatively the bridge piece may be of zinc alloy. The adhesive is preferably waterproof and either an epoxy or polyester resin.

Title: Improvements in axial-flow rotary pumps
IPC: F04D3/00
Filed: 1925-02-20
Abstract: 236,851. Drysdale & Co., Ltd., and Young, J. Feb. 20, 1925. Addition to 216,058. Casings.-In a pump of the type described in the parent Specification, with its discharge branch h in line with its suction branch k, a non- return valve m forms, or is situated in, the wall separating the two branches. A single impeller pump is shown in Fig. 1 and two impellers in parallel are shown in Fig. 2. The pump is connected in series with the main pumps or with the gravity supply and the valve remains open as long as the pressure on the suction side exceeds that on the discharge side. When an additional head is required the pump is started and produces a greater pressure on the discharge side than exists on the suction side. The valve m then closes and the pump works in series with the remainder of the system.

Title: Improvements in the machining of thread-rolling dies
IPC: B21H3/06
Filed: 1943-03-25
Abstract: 562,534. Grinding screw threads. HERBERT, Ltd., A., and TURNBULL, D. G. March 25, 1943, No. 4839. [Class 60] [Also in Group XXII] In a process and apparatus for chamfering the ends of a screw-thread rolling die 24, Figs. 4 and 5, as at 27, the thread-forming grooves and ridges 25 are first cut by a milling or grinding tool and the die is then tilted in two directions relatively to the cutter so that the chamfered grooves 27 may be cut with the'line 27a at the inner end of the chamfer at right angles to the longitudinal faces 26 of the die. The die is clamped by a plate 31 and screws 30 in a holder 16 carried by a base 12, the die being mounted in a support 29 in the holder having an inclined lower surface 29a so that the base 12 may be tilted transversely by a wedge 14 whilst the upper surface of the die remains horizontal in the transverse direction. For cutting the grooves 25 the holder 16 is supported in the base 12 in a parallel sided packing piece 17, Fig. 3, with the upper side of the die in a horizontal plane in the longitudinal direction as well as the transverse direction. After machining of the grooves 25, by a cutter inclined to the edges 26 at the thread angle 28, a gauge 35, consisting of a cylindrical rod cut away on a diametrical plane, is secured to the die with its axis along the required line 27a and an indicator 37 is adjusted to make contact with the gauge whilst giving a zero reading. A screw 36 on the base is also adjusted to contact the gauge 35 in the longitudinal direction. The screws 21 securing the holder 16 to the base are then loosened and the packing piece 17 replaced by a wedge 38, Fig. 2, having the same angle as the chamfer required which is adjusted until the indicator 37 is again in contact with the gauge 35 and giving zero reading, thus ensuring that the line 27a occupies the same position as before and effecting a tilting of the die about this line in a plane parallel to the inclined face 13 of the base 12. The screws 21 may then be tightened, the gauge 35 and indicator 37 removed, and the chamfered grooves 27 machined in line with the grooves 25. For chamfering the other end of the die, the wedge 38 is reversed and the gauge and indicator applied to that end of the die. The longitudinal position of the packing pieces 17 is determined by a screw 18, Fig. 1 (not shown), in the base 12 and that of the die 24 by a screw 34. The angle of tilt imparted by the wedge 14 is between 3 and 6 minutes.
