Abstract: A dressing tool for form dressing of a grinding wheel comprising a cylindrical body 22 having an open groove 32 formed at one end; said open groove 32 adapted for insertion, seating, and clamping of a chisel-edge diamond 36; said chisel-edge diamond being clamped in said open groove in a substantially centered alignment with an axis of said cylindrical body 22, and said chisel-edge diamond simultaneously clamped in said open groove at a negative angle B by a clamping means 42; said centering alignment and negative angle adjustment provided by an associated matching and removable centering gage.

Abstract: This invention pertains to an auxiliary jaw which is adapted to be affixed to a movable member and as this movable member is advanced to and from a workpiece to grip and hold this workpiece when and while the auxiliary jaw is advanced. This auxiliary jaw includes a pivoted jaw member carried by a support member which is preferably secured to the movable member by cap screws. The pivoted jaw member engages the surface portion of the workpiece in local areas as it exerts a gripping force urges the workpiece toward the support surface. Three configurations of jaw assemblies are shown. Each has a pivoted jaw with one configuration supporting the workpiece above the pivoted jaw. In a second configuration the support as a pin means is below the pivoted jaw and in yet a third configuration the pivoted jaws are movable toward and to a support disk for multiple workpieces. Soft jaws, hardened jaws and bias means may be used to bring the pivoted jaw to the desired condition.

Abstract: This application discloses a work-holding chuck particularly for gears with their exterior teeth finished or substantially finished as by grinding, shaving and the like. This chuck has a plurality of hardened and finished pins which are moved and secured in a precise circular array and arranged as pairs on a ring member. A stop is provided so that the gear and the hub portion thereof is precisely located and positioned. Sliding segments are moved along a ramp guide by pneumatic or hydraulic means to bring the formed pins into the formed flanks of the teeth profile to repeatedly and precisely hold the gear by its formed and finished teeth. The held gear is now finished in its bore. Means are provided for readily changing the pins and position of these pins on the chuck so that gears of different pitch, number of teeth and/or lead may be accommodated.

Abstract: This invention pertains to a cutting tool bit as used with and in the back spot facing tool as shown in my U.S. Pat. No. 3,827,821 as issued on Aug. 6, 1974. As shown in this patent the cutting tool bit member has unequal projections and cutting faces and it is contemplated that the shorter blade portion is three-quarters the length and has an effective cutting area three-quarters of the full length blade portion. To insure a smooth and flat spot face a precise grinding of this cutting tool bit is required. It is also required that the chips be directed in a desired spiral away from the cutting tool. An eight degree slope is provided as an angled face on the top surface of the cutting tool. The cutting edge of the cutting tool bit is also relieved preferably by a three degree slope away from the cutting edge.

Abstract: This invention pertains to a replaceable flinger for use with live centers. This flinger is placed as an auxiliary member on the hardened center. In addition to having a forward flinger adapted to withstand the abrasive action of chips, abrasive particles and the like, there is also a land portion on its rear on which the engaging lip of a grease or oil seal rides. When the center is to be reconditioned due to damage to the forward portion of the flinger or because of excessive wear to the seal engaging surface of the flinger, only the grease seal and the flinger need be replaced. This reconditioning does not require the replacement of the hardened center member.

Abstract: This invention discloses a heavy-duty live center for a heavy workpiece usually of 10 or more tons. This center includes an outer quill or housing which is movable in a tailstock housing of a lathe or grinder. This live center incorporates the self-aligning front bearing arrangement shown in U.S. Patent application Ser. No. 643,909, filed Dec. 23, 1975. As described in that application this heavy-duty center has the center spindle bowed by the load and as the thrust increases because of heat, etc. there is a Belleville-type spring arrangement which accommodates the increased thrust. The outer housing or quill in the present invention receives the thrust of the load. The quill is moved into a workpiece supporting condition by the action of a screw on an enclosed nut in the rear of the quill. The thrust is measured by a hydraulic load cell and connected hydraulic pressure gage. This gage is carried on the forward exterior part of the housing.

Abstract: This invention pertains to the construction and method of construction of heavy-duty live centers having a workpiece carrying capacity of from 35 to 250 tons. A quill-type outer member is employed with heavy-duty roller bearings in one portion of this center. Minimum capacity of this type of center is more than a 10 ton workpiece. The rotating spindle in this quill is designed to be supported by heavy-duty bearings which are so mounted in the bore in the quill housing that the spindle is allowed to bow to a determined extent, this bowing occurs when the spindle is loaded with a heavy workpiece. A heavy-duty self-aligning angular radial bearing assembly is carried in the front end of the bore of this live center.
