4 Claims.
This invention relates to material working apparatus, and more particularly to apparatus for pointing terminals of vacuum tubes.
There are various types of vacuum tubes many of which contain terminals of pin-like structures projecting from the bases thereof for forming electrical connections of the various elements of the tubes, through jacks or sockets, with the electrical circuits in which they are to be employed. It is advantageous that the ends of the terminals be rounded or pointed so that their connections with the sockets or jacks, in which they are to be disposed, may be readily made.
An object of the invention is to provide a material working apparatus which is simple in structure, readily operable, and highly eflicient particularly in pointing terminals of vacuum tubes.
With this and other objects in view, the invention comprises a material working apparatus having an apertured member for receiving the terminals of a. vacuum tube and for guiding the terminals into engagement with rotatable pointing elements adapted to point the terminals.
Other objects and advantages will be apparent from the following detailed description when considered in conjunction with the accompanying drawings, wherein Fig. 1 is a fragmentary, longitudinal, sectional view of the apparatus;
Fig. 2 is an end elevational view taken along the line 2-2 of Fig. 1;
Fig. 3 is a vertical sectional view taken along the line 3-3 of Fig. 1;
Fig. 4 is an enlarged fragmentary detailed view of one of the pointing elements, and
Fig. 5 is a vertical sectional view taken along the line 5-5 of Fig. 4.
Referring now to the drawings, the apparatus includes a base I supporting a motor II which constitutes the power means for driving pointing elements I2. The pointing elements [2 are disposed in the substantially conical arrangement shown, supported at spaced positions in apertures of oil impregnated bearing members l4, l and I 6. These bearing members are supported by brackets l1, l8 and I9, respectively, and are mounted upon the base l0, apertures 20 and 2| being formed in the brackets l1 and Hi to allow for the pointing elements to extend therethrough.
A shaft 25, of the motor II, has a coupling 26 mounted thereon, the latter having a knurled or roughened portion' 21 for fixedly supporting a resilient driving element 28. The element 28 is formed of a commercially known rubber composition and is adapted for frictional driving connection with metallic rollers 30 which are fixedly mounted upon adjacent ends of the pointing elements l2. Collars 3|, fixedly mounted upon the pointing elements l2 at the opposite side of the bearing member l6 from the rollers 30, cooperate with the latter in maintaining the pointing elements, particularly their material working ends, at desired locations with respect to each other. A reduced or smooth surfaced portion 33, integral with the roughened portion 27 of the coupling 26, is journalled in a bearing aperture of the bearing member 16, to assist in supporting the driving element 28.
An article locating member 35, of the contour illustrated in Figs. 1 and 2, has a lateral portion 36 integral therewith and provided with a tongue portion 3'! movable in a groove 38 of the base It for adjustment of the member relative to the base and to the working ends of the elements l2. Screws 39, disposed in elongate apertures 40 of the portion 36 and threadedly receivable in apertures 4| of the base l0, serve to secure the member 35 at a selected position. The location of the member 35, with respect to the material working ends of the elements l2, may be further varied through the aid of an adjusting screw 43 which is disposed in a threaded aperture 44 of the member 35, positioned to engage the bracket l1 and locked in any desired position in the member 35 by the aid of a nut 45. Spaced supporting pins 48, mounted upon the member 35 and projecting outwardly in parallel spaced positions therefrom, serve to support an article, namely a vacuum tube 50, terminals 5| of which are to be pointed. A series of apertures 52, depending upon the arrangement of the terminals 5! in the vacuum tube, is formed in the member 35 to receive the terminals and to guide them into the ends of their respective pointing elements [2. In actual structure the vacum tube illustrated is not much larger in size than that illustrated in Fig. 1. For the purpose of illustration, the tube from the end of the tip to the finished ends of the terminals is approximately one and three-quarters inches (1%"). Furthermore, the terminals are approximately one-eighth of an inch A3") between centers excepting at the bottom (Fig. 2). This is mentioned to emphasize the difiiculty in solving the problem of forming or pointing the closely positioned terminals of the electrical unit, namely, the vacuum tube. Thus it is essential to provide the pointing elements I2 within structures capable of engaging the small and closely positioned terminals simultaneously. Added to this is the problem of simultaneously driving the pointing elements in like directions. For this reason the elements I? are of considerable length, it being necessary that they be fanned out slightly so that their rollers 30 may be positioned around and in engagement with the resilient driving element 28.
The pointing elements. l2 are identical in structure and a description of the material working end of one will apply to each of the other ele-. ments. Attention is now dire'cted to Figs 4 and 5, illustrating this structure. Here the end of the element l2 shown is notched, as at 5 4, to receive, a cutting blade 55 of the contour shown, Q2131 ticularly in Fig. 4. A pin 56, extending through aligned apertures of the element upon both sides of the notch and through the cutting, blade 5,5, holds the latter in place. It will be observed that recesses 51 and 58 are formed in the end portions. of the element l2 conforming to the contour hich. to. be. iv e the ermi a 5| s a reelalt.- nhe c i ed e end. o he bl de 5.5.. r heei er l he n t 5 1 d p s d f en er" 1 he eu e-e e 1 3-39 eeu t ee; we w l e at h eenter ine o he eleme t.
