W. E. FISCHER SPLIT BUSHING FOR TOOL POSTS AND SIMILAR APPLICATIONS OF USE Filed March 23, 1931 w em 744721217437 iaiermmm ATTORNEY;
Patented July- 25, 1933 s a UNITED STATES OFFICE i WILLIAM E. FISCHER, F BETHLEHEM, PENNSYLVANIA srLI'r BUSHING ron TooI. rosrs AND SIMILAR APPLICATIONS or Usn App1 ieation filed March 23, 1931. Serial No. 524,656.
However with the present invention, when the binding or set screw is peened or swaged over, all that is necessary is to drive the binding or set screw in a direction to unseat the tapered sections of the split bushing or sleeve, permitting removal of the two sections of the split bushing or sleeve, and then the removal of the set orbinding screw, in which case a new one may be installed. It is to be understood that the particulars herein given are in no way limitative, and that while still keeping'within'the scope: of the invention, any desiredrmodification of details and proportions may be made in the construction of the appliance according to circumstances. I
The invention comprises further features and combination of parts to be hereinafter set forth, shown in the drawing and claimed. In the drawin I Figure 1 is a sectional view. through a support for the bushing, showing the improved split bushing or sleeve as applied, a binding screw engaging through the bushing.
3 Figure 2 is a sectional view through the same support as in Figure. 1, but without the 7. binding screw engaged through the bushing,
Figure 3 is a sectional view of the same support in Figure 1 showing the split bushing in a position ready to be Inserted through the opening in the support and illustrating the two halves of the bushing separated.
-Figure 4 is a perspective view of a tool post, showing the split bushingapplied.
Figure 5 is a perspectiveview showing the two halves of the split bushing separated.
Referring'to the drawing 1 identifies a support, as in Figures 1 to ,3 inclusive or a tool post, as in Figure 4. This support in Figure 4 has a transverse opening 2, and its end 3 has a-tapered bore 4 for the reception of the bushing 5,,which is split and comprises two sections 6 and 7 The two sections (Sand 7 At one end of the opening 2a of the support 654 in Figures 1 to 3 inclusive a depression-9a is formed in the support. This depression 7 is of a shape corresponding to and adapted to receive the head 9 of the bushing. In
other words certain opposite portions of the 705- wall of the depression 9a have straight faces or flats 10a which are engaged by the flats or cut away portions 10 of the head of the split bushing, thereby preventing the bushing y from turning, when the binding screw '11 is rotated. The binding or set screw 11 is threaded through the bushing, and its end 12 may bear on a tool as indicated in dotted lines mounted in the opening 2, thereby re- 1 tainingthe tool securely in posltion. Ordinarily binding or set screws are used in posts or other supports without bushings, and in this instance the end of the screw *which bears upon a tool or other device mounted on the support becomes peened or swaged over, in which case there is no way to remove the screw, to-permit a new one to be inserted and the bore retapped.
However with this present invention in case the screw becomes peened or swaged over it is only necessary to drive the screw out sufiicient to cause the two sectionsof the bushing to unseat from the tapered bore, which will permit withdrawing of the set or binding screw. In case the threads of the two sections of the bushing become impaired a new bushing may be inserted.
The invention having been set forth, what is claimed is: I
In a device asset forth, the combination with a support provided with a tapered opening, of a tapered bushing engaged in the opening, a clamping screw threaded.
through the bushing, said bushing at its larger end provided with a head consisting of diametrically opposite lateral extensions With fiat faces to engage the fiat faces adjoiningsaid; opening, thereby preventing V e turning of the bushing, said hashing comprising two sections whereby the clamping screw may he driven in one direction causing the removal of thetwo sections of the bushing andpermitting a final Withdrawal.
