Abstract: This invention generally pertains to a self-reversing tapping apparatus system, and more particularly, embodiments of this system include an improved coolant system, a reduction of the components which reverse rotational direction, and provides a modular tapping apparatus system.

Abstract: This invention discloses a component marking device to allow components to be marked by using the rotation provided by a CNC type of machine or other machine tool, and which utilizes a stylus which shares the same approximate axis of rotation as the CNC machine and which utilizes rotating impact balls to impart a strong throwing force on hammer pins and a hammer to cause the sudden downward movement of the stylus as desired.

Abstract: Disclosed is a tap driver for rigid tapping, which includes predetermined tension and compression factors to self-synchronize the tap driver. In the preferred embodiment, the tap driver includes helical coils imparted in the tap driver body which allow the attachment body to synchronize axially in response to a force of a predetermined magnitude imparted on the tap. An additional embodiment of this invention provides such a tap driver body wherein the body allows for lateral flexure and movement to compensate for feed error and location error.

Abstract: A golf clubhead to shaft coupling system which includes a flexure joint providing for relative movement between the golf clubhead and the shaft. The flexure joint may be machined into the hosel of the golf club, or may be in a separate coupling piece that couples the golf clubhead to the hosel. In one aspect of the invention, a helical coil is machined into the coupling to provide some relative movement between the clubhead and the shaft for increased golfer “feel” during the golf stroke.

Abstract: A self-reversing tapping attachment comprises a forward drive member and a reverse drive member drivingly engageable with a tap spindle drive member, as well as gear members drivingly engageable with the forward drive member and the reverse drive member, and includes shock absorbers cushioning impact between the driver members and the gear members. An exchangeable chuck holding a tap is detachably mountable on the tap spindle driver, permitting use of taps of different weight and material.

Abstract: A self-reversing tapping attachment comprises a housing including a tap holding spindle member, a forward drive member and a reverse drive member the latter two members being interchangeable with one another; at least one internal removable fastener with external access, and a base member detachably mountable on the housing, unfastening of the at least one internal fastener and the base member permitting removal of the drive members and the tap holding spindle member from the housing. A method for disassembly includes the steps of unfastening the base member, gaining access to the internal fasteners, unfastening them, and pulling out the tap spindle member.

Abstract: A tapping attachment for use in connection with radial tapping comprises a tap spindle member rotatable in a tapping direction, a driven part engageable with a driving part from a power source in a different direction from the tapping direction, a forward drive member engageable with the tap spindle member to drive the tap spindle member in the tapping direction, a reverse drive member engageable with the tap spindle to drive it in a direction opposite to the tapping direction, means for transmitting drive to the forward drive member and the reverse drive member and engageable with the driven part for receiving drive and with the tap spindle member.

Abstract: The invention provides an improved standardized blank adapted for making taps for making tapped holes and an improved positive lock tap holder. A standardized tap blank is provided which is standardized as to diameter, overall length, and shank length. Such a blank is adapted to manufacture a wide range of taps of varying thread sizes, both U.S. and British standards, and metric standard. For broadening the range of capacities that the blanks are adapted for, a set is provided including two additional standardized blanks, standardized as to a different diameter shank length and overall length. Each standardized blank is provided with a square end, standardized as to the square sides and overall length. The standardized tap blanks are further provided with an annular groove to for holding balls.

Abstract: In self-reversing tapping attachments improved ball drive means are connectable to source of rotational drive and drive transmitting means are engagable, with the drive means including at least one driving ball member and with the drive transmitting means defining at least one slot for the ball member, which slot includes a ramp section inclined so that upon engagement between the drive means and the ball member the latter travels upwardly thereby cushioning impact between the drive means and the drive transmitting means. A radially extending member on a tap holder member has a radius of curvature less than the radius of curvature of contact members of the drive transmitting means to cushion impact.

Abstract: A tapping attachment for driving a tapping spindle constructed to be adapted for both direct drive and reverse drive of the spindle. The drive of the spindle is by way of a resiliently mounted dog ring having rigid radially extending drive dogs, extending radially outwardly and inwardly from a drive ring. The driving dogs are rigid, having slanting sides to accommodate clutching engagement and disengagement. Clutching engagement and disengagement occur as a result of relative axial movement as between the attachment and the drive spindle. The drive spindle has a central bore in which is provided an insert member having an axial bore which is connected to a flexible tube within the bore of the spindle, which accommodates relative axial movement, the flexible tube communicating with a similar bore in a tap itself. These bores provide a channel for continuously supplying coolant to the machine and to the spindle itself.

Abstract: A self-reversing tapping attachment employing dog drive includes driver means with at least one drive element for driving engagement with at least one dogging element on drive transmitting means, the dogging element and drive element being such that engagement between them is over an area greater than a point and further includes a drive spindle member for carrying a tap having at least one drive component for engagement with a dogging element on the drive transmitting means, the driver elements and dogging elements providing minimum interference between forward and reverse drive.

Abstract: The invention is a quick change holding device for tools and, more particularly, for taps. The holder has an axially movable collar cooperable with holding elements which can be placed in holding position relative to an annular groove in the tap and released therefrom. The holding elements are curved, that is arcuate individual members having rounded, that is, curved, surfaces on the outsides thereof. The inner rounded or curved surface of the holding element comes into contiguous flush mating engagement with the annular groove in the tap, whereby improved holding capability is achieved.
