| 95 | Method for installing connecting rod bolts | US804933 | 1985-12-05 | US4698885A | 1987-10-13 | Charles E. Frost; Rodney K. Elnick |
| A fixture and mechanism for guiding and installing body bound bolts in the bolt openings of engine connecting rods and the like. The device uses an air cylinder to advance an impact hammer driving push rods to engage the bolts. The air cylinder applies only a moderate force sufficient to advance the impact hammer to a position to impact the bolts. The impact force of the pneumatic air hammer is required to advance the bolts into press fitting engagement within the connecting rod openings. The method of using impact forces to drive the bolts into press fitting engagement while advancing the impact hammer with a lower force air cylinder accomplishes installation of the bolts with a relatively small and low cost fixture and equipment as described. | ||||||
| 96 | Method and apparatus for disassembly of a spot-welded structure | US618574 | 1984-06-08 | US4644656A | 1987-02-24 | Michael J. Chouinard |
| A method and apparatus for removing spot welds from a sheet metal structure is shown. A fluid powered hand punch has a handpiece and an L-shaped extension forming a punch die. An elongated rod extends from a fluid piston within the handpiece to a punch bit, allowing the punch to be conveniently positioned over spot welds in diverse structures. An extension of the handpiece body guides and stabilizes the rod. Spot welds are removed by positioning the punch bit over the weld and entirely punching it out. A tapered punch bit engaging the metal along a partial perimeter of its front face is also shown. | ||||||
| 97 | Rock breaking apparatus | US522301 | 1983-07-20 | US4562974A | 1986-01-07 | Ian G. Bezette; David B. Sugden |
| A tool assembly (4) for working a material (R) such as breaking rock. Assembly (4) includes a tool mounting (17) having a fixed section (18), and a movable section (19) for movement relative to the fixed section (18) in a working direction (D.sub.W) and an opposite return direction (D.sub.R). A tool (34) is mounted on the movable section (19) for movement relative thereto in the working direction (D.sub.W) and return direction (D.sub.R). Limit means (49,50) on tool (34) limits relative movement between tool (34) and movable section (19) to between a tool operative position and a tool operated position. During a working stroke, tool (34) is engaged with material (R) and moved in working direction (D.sub.W) from the operative position to the operated position and thereafter in unison with the movable section (19) under action of a working force applied to tool (34) thereby to work material (R). The tool assembly (4) also includes biasing means ( 29) acting between the fixed section (18) and movable section (19) to absorb the applied tool working forces transferred from tool (34) to the movable section (19), and also to provide a restoring force to the movable section (19) for returning the movable section (19) in return direction (D.sub.R) upon conclusion of the working stroke of the tool (34). | ||||||
