n claims. (c1. l16s- 118) This invention relates to improvements in die sets. Bya die set is meant a pair of die supports composed of a top unit and a bottom unit, to each of which is attached dies, punches, cutters, forming dies or any of the other mechanism conventionally used. The dies, punches, etc., likewise are used in pairs after they have been attached to the die set. Frequently the dies are referred to as male and female dies, such as in the case of forming dies or punch dies. l The conventional die set has two or more xed alinement of the dies when in operation. These iixed guide posts, through use, become worn or out of line, and this out-of-alinement condition is a drawback, as it necessitates discarding the die set and gives rise to considerable waste ofl equipment and loss of time.

tion this disadvantage had been recognized and efforts made to provide structures to eliminate the objection. Usually, however, this was accomplished by the use of collars through which the guide posts extend into the lower one of the supporting members of the die set. Hence, such proposals do not entirely obviate the objection. The primary purpose of the present invention is to remove such objection, and this I accomplish by specially constructed guide posts which may be adjusted to re-establish, correct alinemenvt. This will result in a saving of parts and a very substantial saving in money to manufacturers lengaged in the use of 4die sets. l

With the above object set forth and with other objects in View which will appear as the description proceeds, the invention consists in the novel features hereinafter described `in detail, illustrated in the accompanying drawing and more particularly pointed out in the appended claims.

In the drawing, .t .y Fig. 1 is a perspective view of a die set-provided with my improvements.

Fig. 2 is a top plan view of the same.

Fig.3 is a side elevation, partly in vertical section.

Referring to the drawing, 4 designates the lower stationary member and 5 theupper movable member of a die set, the latter being guided in its reciprocation by means of guide posts E,

which pass through holes 1 bored in the upper member.

' Heretofore, it has been customary to bore holes Prior to my nven- Y guide posts to provide proper apposition and may be clearly understood, and I am aware that post with an enlarged base 8 that rests on the upper surface 9 of the member 4. The base is of larger diameter than thefpost and is provided with drilled holes I0 for the accommodation of dowel pins II, and countersunk holes I2 for the reception of socket head cap screws I3. The dowel pins extend into holes I4 drilled in the member 4, and the screws extend into threaded holes I5 tapped in said member. It may be seen from Fig. 2 that the holes I4 and I5 are arranged about' the axes of the guide posts and obviously either post may be removed from the member 4 whenever desired or may be shifted aboutits own axis. It is also apparent that as the post per se does not extend into the member 4, either post can be shifted toward or away from the other,A

posts having enlarged bases abutting one of said faces and detachably secured to the member havving the last mentioned face, theother member being provided with holes through which the guide posts extend, the portion of the member lto which the posts are secured being imperforate directly in alignment with the posts.

2. A die set comprising opposed members havl ing confronting faces, guide posts having enlarged.

bases abutting one of said faces and detachably secured to the member having the last mentioned face, theI other member being provided with holes through which the guide posts exv tend, the endof each guide post-.adjacent its base f terminating between the faces ofsaid members.

v 3. A die set comprising opposed members'having confronting faces, guide posts having enlarged bases abutting one of said'faces and detachably secured tothe member having the last mentioned face, the other member being provided with holes through which the guide. posts extend, the portion of the member to which the posts are secured being imperforate directly in alinement in the lower member 4 for the reception of the with the posts.

4. A die set comprising a lower member having a substantially plane upper surface, guide postshaving enlarged bases with substantially plane bottoms resting directly on said surface, means detachably connecting the bases of the posts to said member, said member being imperforate directly in alignment with the posts, and

bases provided with plane bottoms resting'directly on said surface, said member being imperforate directly in alignment With the posts,

the base of each guide lpost being aprtured, fas tening means extending through the apertures and detachably securing the bases to saidmember, and an upper member having holes through which the guide posts extend for guiding th member relatively to the lower member.
