Threaded die holder apparatus

Abstract

A threaded die holder apparatus includes an internally threaded die unit and a hollow die-support socket which receives the internally threaded die unit. The hollow die-support socket includes an open slot channel. Die-to-socket attachment means are connected between the internally threaded die unit and the hollow die-support socket. Preferably, the hollow die-support socket includes a plurality of open slot channels. The internally threaded die unit and the hollow die-support socket are arrayed along a central longitudinal axis, and the open slot channel is arrayed in the hollow die-support socket in a direction that is transverse to the central longitudinal axis. The transversely arrayed open slot channels permit application of a lubricant from outside the hollow die-support socket to inside the hollow die-support socket to allow lubrication of a thread-forming operation by the internally threaded die unit.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority based upon my copending Provisional Application Ser. No. 60 / 725,163, filed Oct. 11, 2005.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to die holders, and, more particularly, to die holders especially adapted for turning with a ratchet wrench or drill. [0004] 2. Description of the Prior Art [0005] Die holders are well known in the art, and the following references are representative of some prior art die holders: U.S. Pat. Nos. 2,855,613, 3,715,168, 4,095,917, 4,149,820, 4,856,946, 5,299,895, 5,343,787, and 5,490,746, and German Patent DE3841638. [0006] More specifically, U.S. Pat. No. 2,855,613 discloses a combined turning and threading tool which includes a pair of elongated slots 81 and 82 which are in a main body portion 71 and are arrayed in parallel to a central longitudinal axis. In addition, the elongated slots are arrayed on opposite s...

Benefits of technology

[0021] It is another object of the present invention to provide a new and improved threaded die holder apparatus which may be easily and efficiently manufactured and marketed.

[0022] It is a further object of the present invention to provide a new and improved threaded die holder apparatus which is of durable and reliable construction.

[0023] An even further object of the present invention is to provide a new and improved threaded die holder apparatus which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such threaded die holder apparatus available to the buying public.

[0025] Still another object of the present invention is to provide a new and improved threaded die holder apparatus that provides a pair of elongated slots that are oriented transversely with respect to a central longitudinal axis so that they facilitate application of a lubricant therethrough to the cutting operation.

Problems solved by technology

However, this ratchet-reception portion does not include a plurality of inside planar surfaces which would permit reception of a ratchet drive which has a plurality of complementary exterior planar surfaces.
