Abstract: An orbital lathe for resurfacing a fifth wheel kingpin having a support column insertable between the kingpin and an underlying surface generally axially aligned with the kingpin. A cutting tool is mounted for rotation about a pin axis and has a first positioner for moving the cutting tool radially relative to the pin axis and a second positioner for rotating the cutting tool about an axis generally orthoginal to the pin axis. A driver is provided for rotating the cutting tool about the pin axis to cause the cutting tool to remove material from the kingpin. A transport mechanism acts between the support column and the first and second positioner to move the first and second positioners and in turn the cutting tool along the pin axis.

Abstract: A binding machine is operable to hyper-deflect the rings of a binding element against non-planar surfaces to achieve an advantageously forward presentation of free ends of the rings for ergonomic and convenient insertion of a perforated stack of sheets. An embodiment of the binding machine has a base, a plurality of stationary hooks fixed to the base, and a comb member which is pivotally mounted to the base. The comb member may be fixed to a shroud which is mounted to effect the pivotal movement of the comb member. Additionally, this shroud may be axially shifted. When the binding element is supported against the comb member, the axial and pivotal motions of shroud respectively cause (1) engaging of rings of the binding element with the stationary hooks and (2) uncurling deflection of the rings.

Abstract: A stock stop for screw machines and the like for determining bar stock positioning and which is capable of sensing short stock. The stock stop includes a housing affixed to the machine tool having a slidable sleeve in which a threaded stop is adjustably positioned. A spring biases the sleeve and stop toward the advancing bar and the sleeve is displaced to a stop position by the advancing bar stock. Motion multiplying means multiply the sleeve movement upon engagement by the bar stock to actuate a proximity switch indicating proper advancement of the bar stock and permitting continued machine tool operation. As the components of the stock stop are encased and protected against contamination, a high degree of reliability is attained while providing accurate machine tool control with respect to the presence of adequate bar stock for machining.

Abstract: A boring tool assembly is provided and has a cutting tool mounted on one end thereof and permits the boring of a straight hole through a member. The boring tool assembly includes a boring bar having integral guide members disposed thereon that follows behind the cutting tool and maintains contact with the machined surface just cut in order to keep the cutting tool in proper alignment. To permit the continued use of the boring bar after the outer diameter of the cutting tool has been reduced due to wear, each of the integral guide members are resiliently mounted on the boring bar. This permits the guide members to collapses inwardly to maintain a perfect fit with the pilot pore. This collapse inwardly of the guide members is important to maintain bearing contact of the guide members with the pilot bore if the hole being cut by the cutting tool reduces in size due to wear or if the cutting tool has been re-sharpened or replaced with a different cutting tool.

Abstract: A motor-operated hand-held device (1), such as a drilling device, has a rotary spindle 6 located in and projecting out of a housing (2). Rotational movement of a driving motor (8) is transmitted to a tool (7) situated in an end of the rotary spindle (6). A safety device (11) within the housing (2) prevents deflection of the housing about an axis (A) of the rotary spindle (6) in the event the tool (7) becomes suddenly jammed. The safety device (11) can be activated by a detection device (12) if the tool becomes jammed. The safety device (11) is located inside the housing 2 adjacent to the rotary spindle (6) and is formed of at least two component parts which cooperate in frictional engagement in the event the device is activated. One of the component parts is connected to the housing (2) and the other is connected to the rotary spindle (6).

A nut member is rotationally configured on the body member to move the collet axially within the recess. The nut member has an outer sleeve member and an inner sleeve member concentric within the outer sleeve member. The inner sleeve member is threadedly engaged on threads defined on the body member and contains ball grooves defined on an outer circumferential surface thereof. The outer sleeve member has ball grooves defined on the inner circumferential surface thereof and rolling bodies are operably disposed in the ball grooves so that the outer sleeve member is rotatable relative to the inner sleeve member.

Abstract: This invention provides a device which includes a locator, a kinematic mount positioned on a conventional tooling machine, a part carrier disposed on the locator and a retainer ring. The locator has disposed therein a plurality of steel balls, placed in an equidistant position circumferentially around the locator. The kinematic mount includes a plurality of magnets which are in registry with the steel balls on the locator. In operation, a blank part to be machined is placed between a surface of a locator and the retainer ring (fitting within the part carrier). When the locator (with a blank part to be machined) is coupled to the kinematic mount, the part is thus exposed for the desired machining process. Because the locator is removably attachable to the kinematic mount, it can easily be removed from the mount, reversed, and reinserted onto the mount for additional machining.

Abstract: A collet for holding and precisely locating a cutting tool within a tool holder has a bore constructed to receive a shank of the cutting tool therein, a hydrostatically displacable sleeve received in the bore, a piston received within a passage communicating with the sleeve and displaceable to pressurize fluid within the passage to actuate the sleeve and a retaining nut threadably received on the tool holder to displace the piston to pressurize the fluid within the collet as the nut is rotated on the tool holder. The pressurized fluid within the collet acts substantially uniformly across the sleeve to urge the sleeve into firm engagement with the cutting tool to firmly hold and accurately and repeatably locate the cutting tool within the collet. Also, the pressurized fluid acts substantially uniformly on the interior wall of the collet to substantially uniformly urge the collet into firm engagement with the tool holder to firmly hold and accurately and repeatably locate the collet within the tool holder.

Abstract: The present invention relates to a quick connection device for driving various rotary tools by use of a drive shaft surrounded by a housing. Each tool includes a shank with a groove and a coupling projection. A rotary tool holder tube is mounted on bearings in a supporting tube and is provided with a first quick connection snap coupling which includes balls surrounded by a resilient sleeve and which are capable of engaging the groove in the tool shank. The shank is coupled to the drive shaft by the coupling projection and a slot in the drive shaft. Engagement of the second quick connection coupling joining the supporting tube to the housing simultaneously blocks the resilient sleeve. The quick connection coupling device is used in a surgical instrument which enables a variety of rotary cutting tools to be operated at varying distances from the drive shaft by use of a set of intermediate spindles of various lengths having the same structure as the quick connection device.

Abstract: For influencing the run of a deep hole drilled passage in a metallic or non-metallic material a pusher pad (6) variable in strength and position is interposed between the drill rod (2) driving the drill tool (1) or the drill tool (1) itself and the inner wall of the drilled passage so that it causes a bending of the drill rod such that the drill tool assumes a changed run. The variation in the position and/or thickness of the pusher pad (6) can be fed back to the sensing of the corresponding position of the drill tool (1) and controlled by the results of sensing.
