Straight-line rubbing machine with thrust transmitting members
First Claim
1. A rubbing machine having, in combination, a rubbing shoe, a rigid support spaced from and overlying the shoe, a drive mechanism connected between said shoe and said support and operable to move the shoe back and forth relative to the support, hollow and flexible boot means spaced angularly from one another around the drive mechanism, vertically stiff transmitting means housed within each of said boot means and connected between the support and the shoe for transmitting thrust between the support and the shoe, said thrust transmitting means including means for confining back and forth movement of said shoe to a straight path during operation of said drive mechanism.

Abstract
A rubbing machine of the type in which a support is spaced from and overlies a rubbing shoe and in which the rubbing shoe is connected to the support by a drive mechanism operable to reciprocate the shoe. The rubbing shoe is rectangular in shape with the drive mechanism connected at the center of the shoe, and four flexible boots are connected between the support and the shoe at the corners of the shoe. Four pair of opposed, rigid studs are mounted between the support and the shoe to transmit thrust therebetween, and each pair of studs is mounted within a respective one of the boots with one of the studs connected to the support and one to the shoe. A tongue-and-groove connection between the opposing ends of each pair of studs confines the shoe for linear reciprocation in a straight path.

- 1. A rubbing machine having, in combination, a rubbing shoe, a rigid support spaced from and overlying the shoe, a drive mechanism connected between said shoe and said support and operable to move the shoe back and forth relative to the support, hollow and flexible boot means spaced angularly from one another around the drive mechanism, vertically stiff transmitting means housed within each of said boot means and connected between the support and the shoe for transmitting thrust between the support and the shoe, said thrust transmitting means including means for confining back and forth movement of said shoe to a straight path during operation of said drive mechanism.
- 6. A rubbing machine having, in combination, a generally rectangular rubbing shoe, an elongated rigid support spaced from and overlying said shoe, a drive mechanism connected between said shoe and said support and operably connected to the shoe intermediate the ends of the shoe to move the latter back and forth relative to said support, a first pair of laterally spaced, hollow and flexible boots connected between said shoe and said support adjacent one end of said shoe, a second pair of laterally spaced, hollow and flexible boots connected between said shoe and said support adjacent the other end of the shoe, thrust transmitting means housed within each boot, each of said thrust transmitting means comprising a lower rigid stud connected rigidly to said shoe and extending upwardly toward said support and further comprising an upper rigid stud connected rigidly to said support and extending downwardly toward said shoe, and means interconnecting the upper end of each lower stud to the lower end of the adjacent upper stud to transmit thrust between said support and said shoe while confining back and forth movement of said shoe to a straight path during operation of said drive mechanism.
- 10. A rubbing machine having, in combination, an elongated and generally rectangular rubbing shoe, a rigid support spaced from and overlying the shoe, a drive mechanicm connected between said shoe and said support and operable to move the shoe back and forth relative to the support, and sets of thrust transmitting means located adjacent each of the four corners of said shoe, each set of said thrust transmitting means comprising a lower rigid stud connected rigidly to said shoe and extending upwardly toward said support and further comprising an upper rigid stud connected rigidly to said support and extending downwardly toward said shoe, and means interconnecting the upper end of each lower stud to the lower end of the adjacent upper stud to transmit thrust between said support and said shoe while confining back and forth movement of said shoe to a straight path during operation of said drive mechanism.
