Abstract:
A splined drive body for supporting a plurality of sprockets is disclosed. The drive body is provided with at least one composite drive body spline which consists of a first portion made up of the drive body material and a second portion made up of a different, harder material. The second portion of the composite drive body spline is an insert which includes a force receiving surface and a force transmitting surface and is operable to transmit force transmitted to it into the drive body through a force receiving surface provided on the first portion of the composite drive body spline.
Abstract:
A bicycle seat post and clamp for mounting in the seat tube of a bicycle frame and clamping to the bicycle seat rails. The seat post has a straight section to insert into the seat tube and a preferably toroidal section that is clamped by the clamp. The clamp includes a cradle with hooks at opposing ends that extend around seat rails, and a strap with hooks at opposing ends to extend around the seat rails in the opposing direction. A screw extends between two legs making up the strap for tightening the strap, thereby decreasing the size of the opening formed by the clamp, thus clamping the clamp to the seat post and the seat rails.
Abstract:
Locking the headset of a steering post of a bicycle is accomplished by this invention where the steering post or threaded body projects coaxially through a cylindrical journal mounted at the front end of the bicycle frame. Bearing cups are secured in each end of the journal to accommodate thrust bearings. Each thrust bearing in turn is engaged by a cone. The lower cone is mounted stationary on the fork-steering post of the bicycle while the upper cone is threaded engaged to the mounting post body and is drawn hand tight against the upper thrust bearing. The upper cone is locked against rotational movement by a lock nut threaded on the post body above the upper cone and spaced from the upper cone. The locking configuration is achieved by one or more screws extending through an opening in the lock nut and engaging the upper cone to jam the threaded connections between the lock nut, upper cone and steering post body.
Abstract:
An expander for a bicycle seat support post inserted into a tubular socket of the bicycle frame. The post has an expandable collar which is expanded by means of a wedge-like expanding member which projects from the collar and which is moved axially thereinto by means of a tension link. Movement of the link to pull the wedge-like member farther into the collar is accomplished by a screw angularly supported on the post at an angle of less than ninety degrees to its axis.
Abstract:
A steel insert for transferring load to an aluminum splined body from thin plate like sprockets used in multiple speed bicycle drive systems is held in place by a dovetail tongue. The tongue is fitted into a mating groove in the aluminum spline and together the steel insert and the aluminum spline are the proper width to fit the industry standard spline. The dovetail in the tongue of the insert holds the insert securely in position while handling the aluminum splined body, installing or uninstalling sprockets. Drive load from the sprocket is handled as a compressive load on the insert and the aluminum spline but does not load the tongue. The steel insert prevents the thin teeth of the sprocket from damaging the aluminum body or aluminum spline.
Abstract:
The present invention is directed to a bicycle coasting mechanism. The coasting mechanism includes a plurality of pawls which are rotatably mounted and which are configured to engage a plurality of ratchet teeth. A linkage engages each pawl and causes the substantially simultaneous engagement of each pawl with the ratchet teeth.
Abstract:
An industrial mobile process monitoring system is described which provides a way by which a measurable atmospheric condition, such as temperature, can be measured in real time at a plurality of different locations in a structure such as a kiln, and the information transmitted to a base station computer via magnetic energy linking primary and secondary windings of an air-core transformer.
Abstract:
A rotary phased radial thrust variable drive transmission which is lcoated between an input driving member, such as the pedal-driven sprocket of a bicycle, and an output driven member, such as the hub of a bicycle wheel which are mounted for relative rotation on a common axis, such as the axle of the rear wheel of a bicycle. The transmisison includes radial thrust linkages which are carried by the input driving member for cooperating with a surrounding cam ring assembly having a normally fixed cam profile providing a torsional thrust on the output driven member to cause rotation thereof. The cam ring assembly is selectively adjustable to vary its profile.
Abstract:
A bicycle seat mount for mounting the usual saddle seat including a special post and cooperating clamping bracket. The clamping bracket is adjustable to releasably clamp the wires of the saddle seat to permit forward and rearward adjustment and is attached to the post for vertical pivotal movement about the transversely disposed apex of an angular support surface provided at the upper end of the post.
