wire drawing bench or be wound up into a coil on the terminal block of such a bench or on an individual type of block.
till
The object of the present invention is to pro vide a simple and compact arrangement of fan and ducts whereby a current of air may be passed over a drawing block, whether one in aseries on a bench or operated individually. A further object is'to subdivide such current of air and direct the individual streams in. the most effective cooling relation to the wire that is being wound upon the block. e
To the accomplishment of the foregoing and related ends, the invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawlugs and the following description setting forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.
In. said annexed drawings:--,
Fig. 1 ispartly a side elevation and partly a vertical section through a wire drawing mechanism including the present improved cooling means; Fig. 2 is a vertical section taken on a plane at right angles to that of Fig. 1, as indicated by the line 2-2 thereon; and Fig. 3 is a broken horizontal section withparts appearing in elevation, the plane of the section being in general indicated by the lined- 3, Fig. 1, it being noted that theplane of the sectioned parts appearing in Fig. 1 is indicated by the line 1-1 on said Fig. 3. r
For the purpose of illustrating the present im= proved construction of cooling means, such means are shown in connection with a wire drawing mechanism of the individually driven type such as will be found disclosed in U. S. Patent No. 1,723,313, issued to P. V. Tippet under date of August 6, 1929. It will be understood, however,
that such'coolingmeans are not limited in their application to any such particular type of block but may be advantageously incorporated in benches comprising a plurality of blocks, particularly where the latter are driven by separate motors.
The main frame 1 of the single block wire drawing mechanism illustrated in the drawings is a rectangular box-like structure, preferably formed.-
of an integral casting, the side walls of which are 1931, herial No. 566,612
(@l,2t52d) connected at an intermediate point by a trans verse partition 2 above which is located the driv ing mechanism for the block, as will be presently described. The upper portion of such frame is partially closed off by an annular plate 3 that forms a top for the machine, and located a: short distance therebelow is a correspondingly annular 'webor partition 4, the inner edge of which is joined with the corresponding edge of said top 3 by a vertical wall 5 so as to form a chamber 6 of the general extent. and substantially annular shape clearly indicated in Fig. 3.
The drum or block 7, which is in general of standard construction, is mounted on the upper end of a vertical spindle 8, the lower end of which is journaled in a bearing 9 provided in a supplemental frame 10 of general cylindrical form, Such frame is removably supported, by means of an integral flange 11 about its upper edge, "the circular opening defined by the wall 5, such flange resting on the annular top 3, as shown in Fig. 2, and being bolted or otherwise removably secured to such top. A plate 12,,preierably of conical form, is fitted to the upper end of supplemental frame 10, having a flange 12 that rests upon and interlocks with the flange 11 of said frame, and is secured along with the latter to the whereby the vertical spindle 8 that supports the, b5
block 7 is driven; At the same time said suphit , plemental frame forms a housing for a blower fan,
as will be explained The driving connections comprise a worm 17 on the inner end of a'shaitv 18 that constitutes in effect a continuation or the motor spindle 19, such shaft being journaled in a bearing 20 therefore provide in the adjacent.
side wall of main frame 1. As a matter effect, in the construction shown, this bearing is formed Mill in a boss or hub 15a on the adjacent face of supplemental frame 15, such boss projecting through an opening in the side wall of the main frame; 1. The worm 17 meshes in turn with a worm gear 21 keyed on the lower end of the spindle 8, supplemental frame 10 being cut away at to provide clearance.
The motor will desirably be enclosed, as shown in Fig. 1, in a guard 22, the top 23 of which lies on a level with the top 3 of the main frame, and
jointly supported; upon guard top 23 and main frame top 3 is a vertical shield 24 that more or less completely encloses the mechanism on top or the main frame.
The web a that forms the floor of the chamber 6 in the main frame is depressed at one corner of the latter to form an inlet connection 25 which freely communicates with the interior of the shell that forms the supplemental frame on which the motor is mounted, as just described above. This shell, in addition to thus support-- I the top 3 of the main frame, and thence through aligned openings 28 into the interior of an annular shield 29 that surrounds the lower end of block 7. Such end, it will be noted (see Fig. 2). is in the form of an outwardly directed flange 7a, just above which the cylindrical wall of the drum is provided with a series of radial apertures '71). The shield 29 risesto a level somewhat above such flange 7a, and is itself provided with a rebent lip or downwardly directed flange 30 that has a close workingfit with the edge of flange 7a and is provided with a series of apertures 31 located adjacent the upper surface of flange 7a. The rebent lip 30 serves as a means for preventing the coils of wire, when they become loosened, from dropping down and getting caught between the drum flange 7a and the shield 29'.
The operation of the machine may now be described, giving special attention to the means provided for cooling the drum or block '7 and the coil of wire being wound thereon. The current of air supplied by the blower 26 to the chamber 6 will build up in the latter a substantial pressure which will be in turn conveyed into the annular space within the shield 29. 'From the latter in turn the air is permitted to escape both into the lower part of the drum or block and thence throughthe openings 71) formed in the side wall of the latter, and directly through the open ings 31 formed in the downturned flange 30 on the shield itself. It will thus be seen that cooling currents of air are discharged both through and against the vertical wall of the drum or block. Accordingly, not only is such drum or block effectively cooled, but the wire as it is wound upon such block, whether in a relatively few number of turns for an intermediate pass or in a larger coil in a final stage of the drawing operation, will likewise be cooled by the passage of air therethrough' from the interior of the block and the currents of air striking against its exterior.
Other modes of applying the principleof my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
