Title: Improvements in heavy duty engine starter gearing
IPC: F16D41/22
Filed: 1950-01-25
Abstract: 670,397. Turning-gear. BENDIX AVIATION CORPORATION. Jan. 25,1950 [April 25, 1949], No. 2007/50. Addition to 665,242. Class 7(v) In an improvement in, or modification of, the engine starter gear claimed in the parent Specification there is provided yielding means, such as compression springs 25, for normally holding the overrunning clutch 21, 22 out of engagement, and a friction coupling, for example, shoes 36 and flange 44, between the driving overrunning clutch member 19 and the pinion 2, the friction coupling being adapted to be released in response to rotation of the pinion 2 above a predetermined speed. Upon manual or electromagnetic shifting of the fork 11 the pinion 2 is moved into mesh with the engine gear 3. Rotation of the power shaft 1 is transmitted to a barrel 12 by means of a sleeve 4 splined to the power shaft, the outer end of the sleeve being formed as a flange 9 with radial lugs 14 that engage slots 13 in the barrel 12, which slots also house radial lugs 31 on the driving coupling member 29. The latter has teeth 34 which engage similar teeth 35 on one side of the driving clutch member 19, whilst teeth 21 on the other side of member 19 are normally held by springs 25 out of engagement with teeth 22 of an element 17 secured to the pinion 2; teeth 34 and 35 form an overload coupling. Due to engagement of pinion 2 and engine gear 3, rotation of member 29 causes teeth 34 to cam the clutch member 19 rightwardly by interaction with teeth 35, and so engage the overrunning clutch, the member 19 being held against rotation by the centrifugal friction coupling, the shoes 36 of which frictionally engage the flange 44 on member 19. When the axial movement of member 19 is arrested by a thrust washer 18 interposed between member 17 and the inturned part 16 of the barrel 12, further camming action between teeth 34 and 35 takes place by backward movement of member 29 against its disc loading springs 33 so that torque is transmitted through the overload coupling and overrunning clutch to crank the engine. When the engine starts, the teeth 21 and 22 are cammed out of mesh and the shoes 36 lift to enable the pinion 2 to rotate freely. In a modification, the frictional surfaces of the shoes and flange are tapered.

Title: Improvements in and connected with odometers
IPC: G01C22/00
Filed: 1924-01-25
Abstract: 232,692. Miller, H. C., and Callinan, J. Jan. 25, 1924. Odometers.-In an odometer adapted to be applied to the hub of a motor-vehicle &c. wheel, the fixed spindle k of the disc g upon which the counting mechanism is mounted, is made of a length equal to at least four times its diameter in order to prevent oil from creeping along it and obscuring the reading, and a stuffing-box s is provided around a groove u for the same purpose. The outer casing a which is screwed or bolted to the wheel hub has screwed into it a driving member h into the central bore of which are fitted two packing glands m, o surrounding the spindle k. An eccentric 20 mounted on the end of the plug m actuates the pawl 25 of the counting-mechanism through a strap 22 and a pin 23. The spindle k is resiliently connected to the fixed stub axle 6 by a disc t pinned to its reduced end k<2>. This disc carries a plate 4 having bent and slotted arms 10 adapted to be engaged by projections on a disc 5. Pins or projections 13 on the disc 5 are arranged to engage a slot 14 in a collar 15 on the axle 6, and a tapered coiled spring 17 is provided between the plates 4, 5. A ball-race v is arranged between a steel washer z housed in a recess in the member h and a case-hardened race 1 formed on the disc t. The arrangement of the projections 13 may be modified.

Abstract: 538,492. Stereoscopic apparatus. GRUBER, W. B. Feb. 3, 1940, No. 2161. [Class 97 (i)] A circular carrier for pairs of stereoscopic images is rotatably mounted behind apertures through which the images may be successively viewed. As shown, a carrier 37 comprises two discs having apertures 38 in which singlepicture sections of kinematograph film are mounted, the members of each stereoscopic pair being in diametrically-opposite apertures, alternate pairs being relatively inverted, and the total number of pairs being an odd number. The carrier is mounted on a central pivot 32 in a casing comprising members 26, 27 hinged together ; viewing apertures 30, 31 are provided in each part of the casing, those in the part 26 housing ground glass 44, and those in the part 27 housing eyepieces 41 carrying lenses 43. A lever 33 is mounted on the pivot 32 and may be moved through an angle sufficient to rotate the carrier two image spaces at a time. The lever 33 carries a projection capable of engaging holes 45 in the carrier to rotate the carrier and of sliding from the holes under the influence of a spring 36 returning the lever to its initial position when the lever is released. A spring catch 46 may hold the carrier during the return movement of the lever. The carrier may have spaces 39 bearing reading matter relating to the pictures, the space appropriate to any pair being visible through an aperture 40 in the casing when they are behind the eyepieces.

In stranding wires whose directions of lay alternate along the length of the cable on to an insulated cable core, the two halves 4 of the cable stranding die are maintained under constant pressure regardless of variations in the cable diameter. As shown, the halves 4 are urged together by at least one piston 9 operating in a large volume pressurized cylinder 11 in order to maintain substantially constant pressure upon the halves. The die may also be provided with an elongated key extending on each side and immediately adjacent the bore throughout the length of the die and housed in grooves in the confronting faces of the die, Fig. 5 (not shown), to prevent any stranding wires springing into the gap that may be formed between the die faces as the cable diameter varies. The method of stranding described comprises drawing the wires from supply reels through an oscillating lay plate which alternates the direction of lay periodically and leading the core and stranding wires through the abovedescribed stranding die and then winding the cable on to a take-up drum.

When the coil 20 is de-energised the normal tension exerted on the belt by the reeling mechanism acting to reel it in will free the belt from the brake shoe, which will swing back on its links 21. Shock absorbing means is provided by a triangular blade 30 acting to slice a sheet metal spring 27 as it is withdrawn past the knife. The spring attaches the snubbing unit to an anchoring bolt 29. In a modification (Fig. 6) the brake shoe may be applied by the force of the belt pulling against a bar 136 in addition to the electromagnetic application of the brake. The bar 136 is linked to the brake shoe by links 137 and pulls it into engagement with the belt.
