Abstract: 755,464. Vehicle wheels. FIRESTONE TIRE & RUBBER CO. May 17, 1954 [Nov. 20, 1953], No. 14364/54. Class 144 (2). A wheel construction comprises a disc 12 provided with a plurality of lugs 40 spaced uniformly about its circumference and formed with radially extending surfaces which engage corresponding radial surfaces on portions of removable clamp members 20, and a rim 11 having oppositely disposed angular surfaces 16 forming a circumferential rib 15 shaped to coact with complementary surfaces 29 on the ends of the clamp members 20, the latter being restrained against axial movement and adapted to be moved towards the rim by the movement of adjacent abutting members 21. As shown, the clamp or chucking-member 20 has a flat substantial radial surface which seats against a fixed, flat, radial surface of the lug 40 and terminates in an inclined lower cam surface 36 which abuts against a corresponding surface 31 on the angularly offset foot portion 35 of a wedge member 21. The latter has an upper end surface 32 inclined similarly to the lower surface 31 and arranged to bear against an adjacent surface 37 on the member 20 when a nut 47 is tightened upon a bolt 46 passing through the three members 40, 20, and 21. The bottom end of the wedge member 21 is seated upon the flat surface 50 of a projection 49 which is integral with the lug 40, so that the tightening of the nut serves to increase the outward radial pressure of the concave portions 23, 24 of the bifurcated ends of the members 20. To prevent turning of the rim 11 relative to the wheel, metal driving blocks or lugs 52 are riveted upon the underside of the rib 15 to engage between the pairs of projections 25, 27 and 26, 28, Fig. 4, comprising the bifurcated end of member 20. The axial position of the rim relative to the wheel may be altered by arranging the clamping means on the opposite side of the lug 40 and two further alternative positions are provided by rim 14 similar to rim 15. Fig. 7 shows an alternative form of clamp comprising a substantially U-shaped member 60 with a pair of spaced arms 61, 62 terminating in circumferentially spaced pairs of projections 64, 65 and 66, 67.

Patent GB-147751-A (GB)
Abstract: 147,751. Schaller, C. July 7, 1915, [Convention date]. Multiplying and dividing apparatus; transfer mechanism. - The revolutions-counting mechanism is advanced through one tooth upon each revolution of the main handle by means of a drive which is reversed when the main handle is reversed for division. The part 4 having a toothgap is normally held in the position shown in Fig. 1 by a double spring 7 engaging pins 6 between which engages a locking lever 10 pivoted at 9. The frame 12 carrying these pivots is guided in parallel slots 13 to allow the part 4 to move up and engage the wheel 5. Pivoted also at 3 is a bridge-piece 11 embracing the springs 7 as shown, and formed with an extension 18 pivoted to a frame 19, Figs. 1, 1<a>. The frame is formed with a wide slot 22 through which the main shaft 15 passes, and with two slots 20. 26 connected by a gap 25 and engaging a fixed pin 21. When the handle 2 is turned clockwise, a cam 16 on the main shaft 15 depresses a lever 17 and raises the frame 12. At the same time, a cam 23 engages a, lug 24 and slides the frame 19 to the left, Fig. 1, tilting the bridge-piece 11 to release the right-hand spring 7 from the corresponding pin 6. When the part 10 engages a fixed stop 14, it is forced down and the part 4 turns under the influence of the other spring 7, moving the wheel 5 counter-clockwise. The frame 19 is returned to central position by the spring 29. To reverse the mechanism, the frame 19 is pushed down by hand or automatically so that the pin 21 rides in the slot 26. In this position, a second cam 23 is adapted to engage a lug 28, opposite and in a different plane to the lug 24, to move the frame. When a calculation has been made, the revolutions counter 1 is zeroized as usual by depressing a lever 31, the end of which, according to the present invention, engages under a pin 32 on the frame 19 and lifts the latter, if not already lifted, to the normal position for addition or multiplication. The turning of the handle 2 counter-clockwise reverses the position of the frame 19 automatically. A disk 33, Fig. 5a, on the main shaft 15 carries a pin 34 which engages a pin 35 and rocks a shaft 36 and lever 37 which engages the pin 32, Fig. 5, and forces the frame 19 down. The disk 33 is provided with a recess engaging the end of the shaft 36. When a clockwise turn is given to the handle 2, an incline or cam 38 in the recess forces the shaft 36 endways so that the pins 34, 35 cannot engage, thus. placing the reversing- mechanism out of action. Should a counterclockwise turn be given subsequently during addition, the reversing-mechanism remains unaffected. Depression of the lever 31 to zeroize the counter returns the shaft 36 endways. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the arrangement of a pin on the counter wheel to engage with an offset cheek on the stop lever 10 to effect tens transfer. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to a photographic type-composing apparatus
IPC: B41B21/18
Filed: 1955-05-23
Abstract: 769,656. Photographic type-composing. HARRIS-SEYBOLD CO. May 23, 1955 [May 27, 1954], No. 14785/55. Class 98(1) In a photographic type-composing machine in which selected characters are projected on to photographic material, an optical flat is placed in the image-forming beam in order to form the image of the selected character at a given distance from the matrix and with a given magnification. The fiat is made of material of refractive index N, and has a thickness ND/ (N-1), where D is the distance between the desired image plane and the position at which the image of desired magnification would be formed without the flat. In this way images of different magnifications can be produced in the same image plane by shifting the lens axially and interposing optical flats of different thicknesses. As shown in Fig. 7, the characters are carried by a rotatable disc 10 and are illuminated from a a light source (not shown) and a condenser lens 16. An image of the illuminated character is formed by a lens system 42, mounted in a lens mount 43 carried by a bracket 44 slidable on a grooved bed 40. The image is formed in a plane 45. A second image. is formed by a end system 50 in a mount 51 on the surface of a film 22 passing over a roller 23. Lens mount 51 is carried on a slidable bracket 53, which is urged a spring 56 in the direction of the light source. A number of optical flats 60 (see also Fig. 9) are mounted on a carrier 61 which is rotatable about a spigot 62 by means of a handle 63. 'The handle has an indexing plunger 65 co-operating with holes 66 in a plate 67 to locate the flats properly in the image path. Buttons 71 are mounted on a set portion of the carrier 61. These buttons engage the sloping edge of the carrier 53 which is thereby located along the bed 40 such that the lens system 50 is properly positioned for forming the character image on the film 22. The thickness of the flats 60 is chosen in accordance with the formula quoted above, so that an image of the required magnification is always formed at the surface of the film 22. Empty spaces are left at the end of the row of flats 60, corresponding to the position of the lens system 50 in which no optical flat need be interposed.
