ADJUSTING MEANS FOR CUTTING STEELS Filed Oct. 31, 1940 2 Sheet-Sheet 2 JEJI- Mafia Patented May 20, 1941 UNITED STATES PATENT OFFICE- ADJ USTING- MEAN :fjfiCUTTIN G S'I EELS Application October 31, 1940, 'Serial No. 363,782

12 Claims. (01. 164-118) This invention relates to means for efl'ecting lateral adjustment of the cutting steels of metal blanking, trimming and punching machines of that general class shown and described in United States Letters Patent, No. 2,213,919, issued to me on the 3rd day of September, 1940, the present invention being an improvement thereon.

The object of the invention is to provide means whereby after lateral adjustment of the movable member or cutting steel has been effected, the dowel or connecting pin may be removed to permit detachment and resharpening of the cutting steel or for other purposes without disturbing said adjustment.

A further object 'is to provide cutting steel adjusting means including inner and outer expansible eccentric sleeves and a central locking sleeve adapted to receive a dowel pin, said central sleeve serving to lock the eccentric sleeves in a fixed position of adjustment and the cutting steel and associated parts being removable as a unit from the die shoe so as to obviate the necessity of readjusting the eccentric sleeves when the cutting steel is again positioned on the die shoe.

A further object is to make the dowel of tubular formation with the interior walls at the lower end thereof threaded for engagement with a correspondingly threaded extracting pin so that, by positioning the extracting pin within the dowel and rotating said pin, the dowel will be withdrawn from its socket in the die shoe.

A still further object of the invention is gen-' erally to improve this class of devices so as to increase their utility, durability and efliciency.

The improved mechanism forming the "subject-matter of the present invention may be used in connection with any type of metal piercing or trimming machine, and in the drawings a portion of a conventional machine is illustrated, in which 5 designates the movable member or cutting steel having a socket 6 formed therein and I the lower stationary member or die shoe provided with a seat or socket 8.

The cutting steel adjusting mechanism comprises an outer longitudinally split eccentric .sleeve 9 fitting within the socket 6 and having inner and outer parallel walls, as shown. Fitted within the outer eccentric sleeve 9 is an inner longitudinally split eccentric sleeve Ill having an outer straight wall which bears against the adjacent straight wall of the outer sleeve and provided with an inner tapered wall II, the lower end of which is threaded, as indicated at l2. The upper endsof the inner and outer expansible eccentric sleeves are formed with a series of circumferential recesses or notches l3 adapted to receive the end of a screw-driver or other suit-' able tool for rotating the same when it is desired to adjust the cutting steel laterally with respect to the die shoe. Fitting within the inner sleeve I0 is a central locking sleeve l4 having its outer wall tapered to correspond with the tapered wall ll of the inner eccentric sleeve and provided at its lower end with circumferential threads l5 which engage the threads l2 on the inner sleeve, as best shown in Figure 2 of the drawings, so

that, after the inner and outer eccentric sleeves have been adjusted to move the cutting die laterally with respect to the die shoe, said inner and outer sleeves will be expanded against the walls of the opening 6 and thus lock said sleeves in a fixed position of adjustment thereby to permit removal of the cutting steel when it is desired to resharpen the same without in any manner disturbing said adjustment. The upper end of the locking sleeve I4 is provided with an interior hexagonal socket Hi to permit the sleeve to be rotated with a wrench or other suitable tool to efiect locking of the parts. Disposed within the asindicatedatil. Asameansforextractingorpartiallyelevatinlthetubulardowelpln H from the dieshoe'l,

thereisprovided an extracting pin ll having its 1 lower'end threaded at II for engagement with the interior threads of the dowel. The upper end of the extracting pinis provided with an angularhead-li while the lower. end thereof is formed with a' conical boss 22 adapted to bear against the central portion of the lower wall of thesocketlsothatbyinsertingtheextracting" pin within the tubular dowel and rotating said pin, the hollow dowel maybe quickly withdrawn orextracted from its seat in the die shoe. It will thus be seen that,after the parts are assembled, lateral adjustment of the cutting steel with respecttothedieshoemaybereadily'eifected;

by rotating the inner and outer eccentric sleeves and after the prcperadiustment has been eifected the parts will be eifectually locked'in said adjusted position by rotating the central locking sleeve. It will, furthermore, be noted that, by

' inserting the extracting pin is within the hollow dowel and rotating said extracting pin, the lower end of the dowel may be elevated to aposition above the upper surface of the die shoe 1 so as to permit the cutting steel together with the dowel and adjustingmechanism to be readily slid laterally-as a uniton the die shoe without in anyumanner disturbing the prior adjustment of the parts. After the cutting steel has been'removed and resharpe'ned or any other repairs made thereto, said cutting die together with the dowel pin and eccentric sleeves may again be positioned as a unit-on th'e'die shoe and the without liability of disturbing the previous adnecting' the cutting steel'and die shoe, and it'wlll be seen that by rotating the pin it until the boss 2 contacts with the lower wall of the socket inthe die shoe, said dowel pin will be withdrawn from its socket and elevated to a position above the upper surface of the die shoe so aa'to permit ready removal of the cutting steel to effect resharpening thereof or for other purposes. It will, therefore, be understood that the extracting pin may be used for removing dowel pins regardless of whether the eccentric sleeves fare'associated therewith or not.

In Figure '9 of the drawings, 'there'is illustrated a combined wrench and dowel pin extracting toolwhich may be used to advantage in effecting adjustment of the different parts of the device.-''- The tool is preferably formed from a single'length of metal having an angular extenslon ll constituting a handle and p'rovidedwith a square terminal forming a wrench. The shank of the tool is exteriorly threaded at 31 for engagement with the interior threads on the hollow dowel pin and is provided with a-te'rminal conical boss 3| adapted to bear against and center the tool within the lower wall of the socket in the die shoe, as will be readily understood. A

" different form of tool is illustrated in Figure 10 dowelllmovedtoapositionwithinthesocketl justment of the eccentric sleeves. This is a decided advantage as in all prior devices, as far as I am aware, after the cutting steel has been re-] moved from the die shoe, further adjustments must be made owing to the fact that'the sleeves are not locked in adjusted position prior to rea moval of the cutting steel.

In Figures 3 and 4 of the drawings, there is illustrated a modified form of the invention, in which the notches II in the inner and outer expansible sleeves are omitted and the upper ends of the drawings; in which the shank of the tool is threaded at 39 and the upper end thereof formedwith a countersunk socket Iii constituting a wrenchhead.

It will be noted that by employing an interio 1y threaded tubular dowel and extracting pin in connection therewith, it;is not necessary, to extend the opening for the dowel pin entirely through the die shoe to'permit removalof the of said sleeves formed with angular faces 28 to permitsaid faces to be grasped by a wrench or other suitable tool to rotate the same. In this form of the device, the upper surface of the cut-' ting steel is cut away, as indicated at 24, to ac-' commodate a wrench when rotating the expansibie sleeves. In all other respects the device shown in Figure 4 is similar'to that. shown in Figure 2 of the drawings.

In Figure 5 of the drawings, there is illustrated another form of the invention, in which a solid dowel 25 is employed, the lower end of which- 1s exteriorly threaded at 20 for engagement-with corresponding threads in the socket of the die shoe. In this form of the device, the

inner and; outer walls of the

eccentric sleeves

21 and 28 are preferably tapered and the walls of the socket 2! in the cutting die are correspondingly tapered so as-to assist in holding the parts inadiuste'd .position when the central locking sleeve ll is rotated. The upper end of the dowel 2! is preferably provided with a socketil for the reception of a tool to facilitate rotating the same in engagement with its socket in the die 'dowel as is generally the case as the lower end of the extracting pin, by engagement with the center of the tapered bottom wall of thesocket in'the' die shoe, will eflectually elevate and removethe dowel from the die shoe without the necessity of introducing a releasing tool through the bottom of the die shoe to eflect the removal of the dowel as is now generally the case.

It, will thus be'seen that there is provided simple and compact means whereby any desired lateral adjustment of the cutting steel with respectto the die shoe can be effected and the parts locked in'a set position of adjustment to permit'removal' and replacement of the cutting steel without disturbing or in any manner affecting-said adjustment, thereby not only facilitating and expediting work on metal cutting, and bending machines but also reducing cost of such work to aminimum.

' From theforegoing description, it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary. a v
