Abstract
Abstract A regulating device for regulating the operations of a friction welder is mounted on a slide table which is slidably mounted on the base of the welder. A plurality of regulating members are mounted on the regulating device in a parallel condition, and a plurality of limit switches are disposed in a limit switch box secured to the base of the friction welder. Each regulating member comprises a shaft supported by a pair of brackets secured to the slide table, a dog slidably mounted on the feed shaft, means for providing axial movement of the feed shaft, and means for reading the relation between the set position of the feed shaft and the dog to a feeler of one of the limit switches for precisely actuating the friction welder.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
213 words
In an improved friction welder including a base, a slide table and a spindle head mounted on the base, a spindle rotatably mounted on the spindle head and having means connected thereto for rotating the spindle, drive means mounted on the base and connected to the slide table for moving the slide table toward and away from the spindle, and a plurality of switches mounted on the base and having mechanical actuators, said switches being connected to the drive means for controlling the movement of the slide table by said drive means, wherein the improvement comprises: a regulating device for said drive means, said device including a pair of brackets mounted on said slide table, a plurality of regulating members mounted in parallel on said brackets and aligned with the direction of movement of said slide table, a corresponding plurality of dogs mounted on said regulating members and disposed with respect to said mechanical actuators of said switches to actuate said switches upon movement of said slide table, and adjustable means on each said regulating member for precisely adjusting the positions of said dogs with respect to said slide table, whereby said dogs are positioned to actuate said switches at precise points of travel of said slide table to control said drive means.
Claim 2
Dependent Claim
213 words
In an improved friction welder including a base, a slide table and a spindle head mounted on the base, a spindle rotatably mounted on the spindle head and having means connected thereto for rotating the spindle, drive means mounted on the base and connected to the slide table for moving the slide table toward and away from the spindle, and a plurality of switches mounted on the base and having mechanical actuators, said switches being connected to the drive means for controlling the movement of the slide table by said drive means, wherein the improvement comprises: a regulating device for said drive means, said device including a pair of brackets mounted on said slide table, a plurality of regulating members mounted in parallel on said brackets and aligned with the direction of movement of said slide table, a corresponding plurality of dogs mounted on said regulating members and disposed with respect to said mechanical actuators of said switches to actuate said switches upon movement of said slide table, and adjustable means on each said regulating member for precisely adjusting the positions of said dogs with respect to said slide table, whereby said dogs are positioned to actuate said switches at precise points of travel of said slide table to control said drive means.
Claim 3
Dependent Claim
61 words
An improved friction welder as set forth in claim 1, in which each said regulating member comprises a shaft having one of said dogs and one of saiD adjustable means mounted thereon, and in which said adjustable means on each said shaft includes means for reading the position of contact of the dog on that shaft with its respective switch actuator.
Claim 4
Dependent Claim
108 words
An improved friction welder as set forth in claim 2, further comprising a plurality of sleeves having internal threads and being mounted on one of said brackets, said shafts are threadably received at one in said respective sleeves and received at their other ends in the other of said brackets, said adjustable means comprising a plurality of thimbles mounted respectively for axial sliding movement on said sleeves, each said thimble being fixed to its respective shaft for rotating said shaft, and in which said means for reading the position of contact of the dogs with the switch actuators includes markings on said sleeves and thimbles comprising vernier scales.
Claim 5
Dependent Claim
111 words
An improved friction welder as set forth in claim 2, further comprising a plurality of sleeves mounted respectively on said shafts, each said sleeve having an externally threaded portion and having a reduced smooth portion at one end, and in which each said dog comprises a thimble having internal threads and being received respectively on said threaded portions of said sleeves for adjustable movement along said sleeves, each sleeve having a locking nut thereon for locking said thimbles in position on said sleeves, and in which said means for reading the position of contact of the dogs with the switch actuators includes markings on said sleeves and thimbles comprising vernier scales.
