Referring more particularly to the drawings, there is illustrated a die viewer generally indicated by the refer ence ‘character 10 comprising a suitable housing 11, the pl-ained. The assembly of the die chuck will now be dealt with, reference being had particularly to FIGURES 3, 5 and 6., The sleeve 37 mounts a bearing 53 therewithin, the hear ing 53 having a bore 54 of ‘a diameter to rotatably ‘receive top wall 12 of which has a wall portion 13 formed at an 45 a tubular extension 55 integrally formed with a head 56 angle to the front wall 14 and is provided with a suitable forming a shoulder in abutting relation with the adjacent medially positioned ?anged opening 15 for mounting of a end of the sleeve 37. The tubular extension is of a length to extend beyond the bearing 49 and has ?xed thereon a frame 16 for support of a lens, and since the latter must be replaceable to obtain proper magni?cation, the frame pulley 57.

The left hand side wall 18 of the housing has an ex With reference to FIGURE 5, it will be seen that the teriorly mounted switch 19 and further is provided with a die chuck 59 is detachably mounted upon the outer face substantial opening 20 permitting access to the interior of the head 56. . The chuck 59 has an annular recessed seat 60 for receiving the die holder 61, the latter being of the housing, for a purpose presently to be explained. Within the housing 11, adjacent the front wall 14, a pedestal 21 is suitably secured upon a base 22, which as here shown is detachably connected within the walls con stituting the housing. Upon and secured to the base 22 there is a support member 23 positioned in the vertical medial axis of the housing having a rearwardly inclined face 24 (see FIGURE 3) and as better seen in FIGURE readily removable therefrom as will be explained. In order to'provide illumination for inspecting a die supported in the die chuck 59, a suitable metallic tube 62 is employed, through which the electrical wires 63 have 60 been threaded and electrically connected to ‘a socket for support of a bulb 64. The tube is bent into substantially U-shaped formation, one leg 65 of which is passed through the open end 66 of the sleeve 55. The tube 62 is preferably welded to the outer periphery of the sleeve 5, the support member 23 is formed with a pair of threaded openings 25 for mounting of a dove-tailed plate 65 37 as indicated at 67, for support purposes, and the leg 26, by means of screws 27 complemental to the openings 25 of the support member. The opposed jaws 28 of the dove-tail plate 26 receive complemental side walls 29 of an adjustable plate 30, the plate being held in adjusted positions by means of screws 31 engaged through threaded openings 32 formed in the jaws 28 so as to impinge upon a pressure plate 33 to 65 is given an inclination, as best seen in FIGURE 5, so that the light rays emanating from the bulb 64 will strike the die 68 at a desirable angle for observation through the magnifying lens 69. The wires 63 of the lighting means and the wires 70 of the motor are electrically connected with the switch 19 and a source of electrical power so as to 'be energized 3,094,416 9 4; do simultaneously, althoughv if desired, separate switches may be employed for each of the devices. The face 24 of the mounting block 23 is formed at an angle of. 90° and: consequently the inspectionrnechanism supported on said block will be at the same angle, present retracting said adjustable plate toward and away from said view opening and a magnifying ‘lens mounted in said view opening. 2.
