Title: Improvements relating to vehicle wheels
IPC: B60B3/18
Filed: 1928-01-17
Abstract: 283,959. Booth, W. N. Jan. 21, 1927, [Convention date]. Detaching from, and attaching to, permanent hubs.-The barrels 5, 7 of the permanent and detachable hubs 1, 2 respectively are spaced by a sleeve 11 having a driving fit in the hub 2 and clamped against a shoulder 14 on the hub 1 by a nut 16 which is threaded on the hub 1. The nut 16 is externally threaded to receive a capnut 19 which jams against a collar 21 on the outer end of the hub 2. The latter is formed at its inner end with a flange 8 which is bolted to a flange 6 on the hub 1. Conical depressions 8<1> around the bolt holes in the flange 8 engage corresponding recesses in the flange 6 to take the drive. The flange 8 is also formed with a corrugation 8<2> adapted to abut against the flange 6. In the preferred form, when the sleeve 11 is jammed against the shoulder 14 there is a slight clearance between the corrugation 8<2> and the flange 6 and a slightly greater clearance between the part 8<1> and the flange 6. By this arrangement, as the nuts 9 are screwed up on the bolts 10 the flange 8 is distorted so as first to jam the corrugation 8<2> against the flange 6 thereby in creasing the tension of the spokes carried by the flange 8. As the nuts are then screwed home, the parts 8<1> are jammed into their seatings, the resiliency of the metal in the flange 8 reacting with a locking effect on the nuts. In a modification, the sleeve 11 is formed from sheet metal with a corrugated outer edge on which the hub 2 is seated. The, nut 16 may be shouldered to take a standard hub-cap.

Abstract: 1,030,191. Bowling alleys. AMERICAN MACHINE & FOUNDRY CO. Jan. 15, 1963 [Jan. 16, 1962], No. 1796/63. Heading A6D. A system for indicating to a bowler the optimum path for the second ball of a frame in the pin bowling games comprises an indicator operated by a ball path selector unit, the latter being primed for operation by means (such as switches on the pinsetter deck) which sense the pins remaining standing on the playing deck after the first ball of the frame. The ball path selector unit comprises a plurality of groups of relay-operated, normally open contacts, each group of contacts corresponding to a particular pin position, and the contacts thereof being closed when the pin sensing mechanism detects that the corresponding pin is standing on the playing deck. The contacts are additionally wired in circuits corresponding to different pin combinations, the circuits each including means such as a lamp or switch forming part of the indicator. Depending on the combination of pins remaining standing after the first ball of the frame, the associated circuit of contacts in the ball path selector unit is made, and the indicator operated to illustrate the optimum ball path for that particular pin combination. The lamps or switches referred to above respectively illuminate arrows on an indicator board (Fig. 11), or control the travel of an index number 152 round the periphery of the indicator board (Fig. 8) so that the index is arrested at the optimum point of entry of the ball into the array. The indicators illustrated additionally comprise an array of lamps corresponding with an array of ten pins on the playing deck of the alley, the lamps being selectively operated by the pinsensing means to give a visual indication on the indicator of the pins remaining standing after the first ball of the frame. The apparatus may also comprise switches for operation by the bowler and which control means on the indicator for indicating the optimum ball path for the first ball of the frame.
