Abstract: An improved shopping cart brake for attachment to the rear leg of a shopping cart is disclosed, the brake for preventing the rotation of a non-inflatable tire on the rear leg of the shopping cart. The shopping cart brake includes a connecting arm, which is removably and adjustably attached to the rear leg of the shopping cart. The brake also includes a split yoke, which is pivotally connected to the connecting arm. The split yoke has two braking flanges which engage and apply frictional force to the sides of the non-inflatable tire to prevent the tire from rotating. An actuator is also included, the actuator being integral with the split yoke and for applying force to the split yoke to engage the braking flanges with the sides of the non-inflatable tire. The shopping cart brake also includes an adjustable tension bar between the braking flanges which may be used to increase or decrease the frictional force the braking flanges apply to the non-inflatable tire.

Abstract: A self-adjustment mechanism for a brake system includes a first sprag clutch seated in a support. An eccentric serves as an inner race for the first sprag clutch and as an outer race for a second sprag clutch. A timing assembly serves as an inner race for the second sprag clutch and includes first and second spaced-apart pins projecting from a surface. An arm is pivotally connected to the timing assembly and positioned between the pins. A brake apply cam engages a first end of the arm so that it pivots with respect to the timing assembly. As the arm pivots, a brake apply piston is engaged. A pivot center of the arm is selectively rotated by the eccentric to maintain the phase relationhip of the cam and the brakepack as the plates wear.

Abstract: A shock absorber is constructed with a hollow cylinder within which a first piston is disposed to move coaxially. A well is defined within the first piston to receive a second piston. The first piston is also provided with longitudinally extending dampening passageways and relief passageways. A cavity of variable volume filled with a compressible fluid, such as air, is defined between the two cylinders. At the start of a stroke of movement of the first piston within the cylinder, the additional length of the piston rod which enters the cylinder as the first piston moves toward the blind end of the cylinder increases pressure on the compressible fluid within the cylinder. The second piston is thereby pressed further into the first piston and ultimately closes off the dampening passageways, thereby preventing further movement of the first piston and increasing the dampening characteristics of the shock absorber.

A second braking element having spaced opposed webs located at opposite sides of the first element is guided by guide pins fixed to one element and received in bores in the other for movement between a braking position wherein a work piece strip is frictionally gripped between one side of the first braking element and the opposed web of the second and a release position in which the opposed web is disengaged from the strip.

The brake unit includes a piston housing in which an annular piston is mounted for reciprocal movement towards and away from a disc housing defining a disc chamber in which a plurality of interleaved non-rotating and rotating discs are disposed. A pressure plate is mounted for reciprocating movement towards and away from the discs and is operative to apply clamping forces to the discs in order to generate braking torque.

Selective reduction of pressure to the piston effects braking action. A piston-to-reaction plate seal inhibits coolant flow between an inner face of the pressure plate and the adjacent disc.
