Title: Improvements in or relating to handle grips
IPC: B29C63/06
Filed: 1921-11-22
Abstract: 197,705. Plantation Rubber Manufacturing Co., Ltd., Underwood, G. F., and Luffsmith, W. Nov. 22,1921. Handles.- Handle-grips for sporting implements are formed from crepe and like raw sheet rubber, which is first treated with a solution to render it pliable, such as a solution of carbonate cr silicate of soda or potash which may be heated, and is then formed on a former or on the handle itself, and is vulcanized by a cold process, such as the Peachy process. Where rigidity is required a surface treatment of tar, shellac, resin or celluloid dissolved in naptha or ether &c. may be applied. Fig. 1 shows a tubular grip for a racket, formed from a sheet of crepe rubber a connected at the edges b by a strip c soluticned on. The ends may be turned over as at d, and may be stuffed with a padding material e, Fig. 2. In a modification the tubular grip is formed from two sheets placed together with the edges overlapping for fixing together on a mandrel; in another modification a tubular grip is formed by cutting the overlapping rubber to unite it, the ends being turned over, or bound with strip rubber. A strip for winding spirally on a handle, or fixing on, may be made by attaching a fabric, or warp threads, or warp and weft threads, as a lining to the crepe sheets. The crepe sheet lined or not with fabric may be attached to a handle by lacing the edges together by a cord &c.

IPC: B65H29/60
Filed: 1962-08-16
Abstract: 1,061,144. Delivering sheets. J. V. BAILEY, G. C. FORTIN, P. R. PRICE, W.S. FORSTER and M. C. STANLEY. Aug. 16, 1963 [Aug. 16, 1962; Oct. 10, 1962], Nos. 31425/62 and 38435/62. Heading B6H. Apparatus for removing selected sheets from a stream comprises a suction drum consisting of a rotating sleeve (not shown) mounted on a stationary core 414. The core has two sets of intercalated circumferential grooves 416 and 416a. Grooves 416 are connected to a source of suction via valve means 451, 452. Grooves 416a are permanently connected to the source of suction. The sleeve is provided with two sets of apertures co-operating with the grooves. A valve stem 419 is intermittently operated to apply suction to the grooves 416 and remove a selected sheet from the stream. The selected sheet is finally conveyed to the stacking position by suction applied to the grooves 416a. The sheet is stripped from the drum by strippers engaging grooves in the drum sleeve. Some of the apertures in each set are enlarged lengthways to assist in holding the corners of a sheet to the sleeve. An extension 433 of the valve stem 419 has a head 434, Fig. 8. A pivoted lever 441 resting on a rotating cam 443 moves the valve stem back and forth to apply suction to the grooves 416 out of phase with the position of the apertures. When it is required to remove a sheet from the stream, a pivoted latch 444 is withdrawn by a solenoid 449 and suction applied to the grooves 416 in phase with the position of the apertures.

Title: Improvements in fuzes for ordnance projectiles or bombs
IPC: G04C23/02
Filed: 1938-10-31
Abstract: 510,065. Projectile fuzes. MEFINA SOC. ANON. Oct. 31, 1938, No. 31464. Convention date; Nov. 6, 1937. [Class 9 (i)] A projectile fuze comprises in combination a movable striking member, a movable locking member adapted to prevent actuation of the striking member, a reversible escapement controlling the movement of the locking member, and a spring-loaded bolt which normally prevents movement of the locking member from the locking position and is retracted against the action of its spring by the effect of inertia when the fuze is in flight, the locking member and bolt having coacting surfaces whereby the locking member is restored to the locking position by the bolt when the latter, after partial retraction, is restored to normal position by its spring. Fig. 1 shows a construction of projectile fuze in which the striker 10 is normally restrained. from moving towards the detonating pellet 11 by a rack 12, the teeth of which engage one of the wheels of the gear train of a reversible escapement 13 holding the rack in the position shown. The holder 14 of the pellet 11 is like. wise prevented by the rack from moving towards the striker 10. When the projectile is fired, the rack under the action of centrifugal force or of a spring tends to slide radially outwards with a movement retarded by the escapement, but such radial outward movement cannot take. place until a bolt formed by a tongue on an annular weight 15 has by inertia been removed from the path of the rack against the action of a spring 16. When the tongue has been fully withdrawn from the path of the rack, the weight 15 is automatically retained. in its retracted position by the expansion of a split elastic ring 17 and the fuze is armed. Should the projectile, in the course of handling receive an accidental blow or shock, the weight 15 with its tongue may be partially retracted and as the rack has an inclined face 18 abutting against an inclined face 19 on the tongue, the rack may move a short distance outwards. Owing to the action of the escapement, this outward movement will be much slower than the movement of the weight so that when the impulse which has moved the weight is spent, the spring 16 will push the weight back before the rack has moved across the path of the tongue. The action of the tongue surface 19 against the rack surface 18 then forces the rack back to the safety position, the escapement spring being by this means rewound. Figs. 5 and 7 show a modification in which the rack 12 is replaced by a wheel 20 of the escapement 13. This wheel, which is rotatable about a stud 23 under the influence of a spring 24, is held, in the unarmed condition of the fuze, by an inclined tongue on a weight 21, corresponding to the weight 15, Fig. 1, and is provided with an aperture adapted when the fuze is armed to be brought into register with an aperture 26 to allow of a free passage for the striker.

Title: Improvements in calculating apparatus for determining ranges and bearings
IPC: G06G1/04
Filed: 1923-12-17
Abstract: 223,086. Simpson, J. Dec. 17, 1923. Plane-trigonometry calculators.- An apparatus for determining at one point the range and bearing of a target, given the range and bearing from another point, comprises a graduated dial and arms mounted thereon and connected so as to reproduce the triangle formed by the target and the two points. The invention is described in connection with the problem illustrated in Fig. 5, wherein a ship B receives the range AD and bearing a of an enemy ship D as observed from the flagship A and it is required to know the range BD and bearing b. In the form shown in Fig. 1, a dial 5, graduated in degrees, is rotatably mounted and is provided with a boss 8 in which can slide radially a. bar 10 pivotally connected at 12 to a graduated arm 15 guided by a channelled bar mounted for parallel motion by means of links 18. A slide 19 on the arm 15 is pivotally joined to a slider 25 embracing a second graduated arm 26 pivoted co-axially with the dial 5 and extended to form a pointer 31. To solve the triangle ABD, the dial is turned with respect to the stationary pointer 7 in order to set the bearing angle a, and the bar 10 and therefore the arm 15 are moved transversely by turning the set screw 11 until the distance AB is set along the scale 13. By moving the slider 19 along the arm 15 to the communicated range AD the range BD can be read off on the arm 26 and the bearing b found by consulting the pointer 31. In a modified construction, the arm 26 is replaced by a spring-drum graduated to exhibit ranges through an observation aperture and connected by a cord to a pointer similar to the pointer 31.

Title: Quick release fastener for apertured workpieces
IPC: F16B21/02
Filed: 1964-08-06
Abstract: 1,051,000. Stud fasteners. ELASTIC STOP NUT CORPORATION OF AMERICA. Aug. 6, 1964 [Aug. 8, 1963], No. 32129/64. Heading E2B. A quick release fastener 10 for apertured workpieces 12, 14 one of which as a non-circular aperture 16 comprises an axially extending shank 20 intgral with an head 24, at least one clamping surface 26 integral with the shank and projecting outwardly therefrom a radial distance greater than a minor dimension of the non-circular aperture, said clamping surface or surfaces being displaced axially from said head so that when the fasteners and workpieces are assembled and the clamping surface or surfaces rotated to coincide with the said minor dimension, the workpieces will be secured between the head 24 and said clamping surface or surfaces 26, and rotation precluding means 46 integral with the shank 24 for positively precluding rotation of said clamping surface or surfaces beyond said assembly rotation and releasably retaining said clamping surface or surfaces in this position against unwanted rotation. The shank 20 has two opposed protuberances 22 projecting radially outwards with clamping surface or surfaces 26 displaced from portions 28 of the head 24 a distance less than the thickness of the workpieces 12, 14. The diameter of the circular aperture 18 and the minor dimension of aperture 16 are smaller than the normal radial extent of the protuberances 22 which distance is smaller than the major dimension of aperture 16. The shank 20 has an axially disposed slot 34 to make the shank resilient so that as the fastener is inserted into aperture 18 the legs 36 so formed are forced towards each other by the edge of aperture 18 riding on cam surfaces 38. The axial contours of the surfaces 38 ensure that the fastener rotates on application to the aperture 16 until the protuberances are aligned with the major dimension. When the fastener has been inserted through both apertures it is rotated a quarter turn facilitated by lead-in surfaces 40, the head portions 28 being elastically deflected to establish a clamping force between the head 24 and clamping surface 26. Flat surfaces 46 engage the side walls 30 of aperture 16 after the quarter turn to stop further rotation in the same direction. The fastener is released by rotation in the opposite direction.
