MANUFACTURE OF SHAET S.
Application filed January as, 1920. serial to. assess.
To all whom it may "on E provided with shoulders usually for the purpose of limiting the movement of the shaft or for retaining some object which is placed upon the shaft.
It has usually been the practice to manufacture such a shaft from a bar stock at least as large in diameter as the diameter of the shoulder with which the sh'aft'is to be provided, and to cut away the material of the bar on either side of the shoulder in order.
to produce the main body of the shaft having the required diameter less than the diameter of the shoulder. Such a process entails the use of considerable time of a skilled workman and also the loss of considerable material especially where the main body of the shaft is considerably longer than the length of the shoulder and where the diameter of the shoulder is substantially greater and in alignment with the groove 21; then the washer 22 is squeezed asshownin Fig.
than the main portion of the shaft.
It is an object of the present invention to form the main body portion of the shaft separate from the shoulder and to apply thereto a separate shoulder in a simple and substantial manner- By such a process considerable waste of time and material will be eliminated. A further object of the in vention is to provide an apparatus by means of which the foregoing method may be carried out.
Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred embodiment of the present invender as applied to the shaft in a temporary manner; Fig. 4 is an end view of same; Fig. 5 is a longitudinal sectional view of the apparatus for squeezing the shoulder upon the shaft, the shaft and shoulder being shown in elevation;
Fig. 6 is a longitudinal sectional view similar to Fig. 5 showing the relation of the parts after the process has been completed.
' In the drawing, the present invention is shown as app-lied to the provision of a shoulder upon a shaft having a main body portion of substantially "uniform diameter; Such a shaft is indicated by numeral 20. It can be readily seen that shaft 20 can be manufactured very cheaply from a bar of stock slightly larger in diameter with very little waste of material and with slight expense for workmanship. Shafti20 is provided with a groove 21 which is formed in a portion of the shaft which is subsequently to be provided with the shoulder.
A washer 22 is provided having an exter-'- nal diameter greater than the required diameter of the shoulder and an internal diameter slightly greater than the diameter of v the main body portion of the shaft 20.
The washer 22 is placed over the shaft 20 4 to hold it temporarily in place within the 22 to be located correctly with respect to the groove 21 while the washer is being squeezed permanently in place in the manner to be-described. Hence'the use of other locating devices forthe accurate alignment of the washer and groove iseliminated.
The shaft and washer are next supported by a block 25 having a central bore 26 slightly greater than the diameter of the main body portion of shaft 20 and having an extension 27, the external diameter of which is slightly less than the required diameter of the finished shoulder. A die 30 having an internal tapered bore 31is arranged in axial alignment with block 25 and shaft 20 and pressure is applied axially of the block 30. As said block 30 moves from the position shown in Fig. 5 to position shown in Fig. 6 the washer 22 will be squeezed inwardly so that its internal diameter will be reduced to that of the diameter of the grooved portion 21 of the shaft 20 and nee so that its external diameter will be reduced to that required for the finished shoulder. This deforming process while reducing the diameters of the washer causes the washer to increase in thickness. In this manner the sides of the washer are firmly compressed against the sides of the groove 21.
By making the walls of the tapered bore 31 comparatively smooth and hard, and by maintaining the blocks and in correct axial alignment with the shaft 20 the external periphery of the finished shoulder will be fairly round and will be fairly concentric with the shaft 20.
This operation may 'be repeated by removing the block 30, from position shown in F 6 and by removing the finished shaft from the block 25 and replacing the same by another shaft 20 to which is temporarily secured a washer 22.
While the form of mechanism herein shown and described constitutes a preterred form of embodiment of the invention, it is to be understood that othertorms might be adopted, all coming within the scope of the claims which follow.
What I claim is as follows:
1. The process of manufacture of a shaft. having a shoulder which consists in providing the shaft with a groove; in making a washer having a thickness less than the width of the groove, and an internal diameter slightly greater than a portion of the shaft whereby the washer may be readily placed in alignment with the groove; in initially deforming the washer so that the washer enters the groove at portions thereof in order to support the shaft; in supporting the washer axially while squeezing the Washer so as to reduce its internal diameter and to increase its thickness whereby the groove, will be substantially occupied by a portion of the washer.
2. The process of manufacture of a shaft having a shoulder which consists in providing the shaft with a groove; in making a washer having a thickness less than the width of the groove, and an internal diameter slightly greater than a portion of the shaft whereby the washer may be readily placed in alignment with the groove; in initially deforming the washer so that the Washer enters the groove at portions thereof in order to support the shaft; in supporting the washer axially While applying pressure at the periphery of the washer and ra dially thereof, whereby to reduce its internal diameter and to increase its thickness whereby the groove will be substantially occupied by a portion of the washer. lln testimony whereof he ailixes his sigma ture.
