DIAMOND TOOL FOR DRESSING GRINDING WHEELS, ETC
Filed April 27, 1956 IN VEN TOR. 7
ATI'ORNE Y6 United States Patent DIAMOND TOOL FOR DRESSING GRINDING WHEELS, ETC.
Joe Loecy, In, Chardon, Ohio Application April 27, 1956, Serial No. 581,063
6 Claims. (Cl. 12539) The present invention is for an improved diamond tool for use in dressing grinding wheels and the like and is of the same general type as the device disclosed in my copending application Serial No. 490,577, tiled February 25, 1955, which issued as Patent No. 2,761,441, dated September 4, 1956.
As noted in the above co-pending application, it is common practice in such a device to turn the diamond-carrying member from time to time so as to present a fresh surface portion of the diamond to the wheel and thus prevent uneven wear of the diamond and thereby prolon the useful life of the diamond.
The present form of device, like that above referred to, is intended for use in those situations where there is not suflicient space for such automatic mechanism as I have provided in other installations for effecting such adjustment of the diamond. For instance, a diamond tool might be of such small dimensions as three-sixteenths of an inch by one-half of an inch, although it is to be understood that the present invention is not limited to any particular dimensions. It is here contemplated also to avoid the necessity of otherwise disrupting the position of the diamond tool in order to effect such rotary adjustment of the same.
Therefore my present invention contemplates the provision of a comparatively simple and inexpensive and yet effective means for mounting the diamond tool in its shank, that will at the same time permit ready and dependable manual rotary adjustment of the same without involving. any changes in the assembly and without re quiring the provision of any other parts.
Another object is to provide such a device in the form of an improved unit that may be conveniently assembled in its holder for operation thereby or removed therefrom with the same convenience.
Another object is to provide such a device that is particularly well adapted for use under conditions of restricted space that require such a tool to be of comparatively small dimensions.
The method of making my present improved device constitutes another object of this invention.
Other objects will appear from the following description and claims when considered together with the accompanying drawing.
Fig. 1 is a view, partly in elevation and partly in section, illustrating my present improved structure;
Fig. 2 is an end elevation thereof.
It is to be understood that the present form of disclosure is merely for the purpose of illustration and that there might be devised various modifications thereof without departing from the spirit of my invention as herein set forth and claimed.
In my present form of device, as herein illustrated, the tool has the shank 1 that is adapted to be assembled in fixed position by means of a set screw S within a holder that is here indicated in a general way by reference letter.
H. The shank 1 is adapted to receive and to hold a diaice . 3 and 4, each of which is in the form of a frustum of a cone with their smaller ends joining the cylindrical portion 2. Immediately forward of the portion 4 is, a cylindrical portion 5 while the forward end portion 6 of this tool member is of polygonal form, as for instance hexagonal, adapted for engagement by a standard wrench for turning the diamond tool. The diamond D may be mounted in the tool member in the usual manner.
The shank 1 of suitable material may be appliedto the tool holder by casting, swaging or spinning the same about the portions 2, 3, 4 and 5, and there will be selected a material for the shank 1 that will assume sufliciently tight frictional engagement about the diamond tool for the purpose herein contemplated. The idea is to effect in this manner a dependable frictional interengagement between the diamond't-ool and the shank 1 that will at the same time permit only rotatable adjustment of the tool within the shank 1 and in which such frictional engagement will be suflicient to hold the tool in the position to which it may thus be turned. That is, there will be suitable frictional interengagement between these parts that will hold the tool in the position to which adjusted and yet will permit such rotatable adjustment to be effected by merely turning the tool with a wrench applied to the. hexagonal surface 6 thereof. As a means of facilitating such turning of the tool within the shank 1 and in order to ensure against breaking of the metal at the interengaging surfaces during such adjustment, the surface portions 2, 3, 4 and 5 as well as the rear end of the diamond tool may be provided with a coating of suitable lubricant 7, as for instance graphite.
It is to be understood that the particular form of the re-entrant neck portion 2, 3, 4 of the tool may be varied according to the particular material employed and also according to whether such interengagement is to be effected by the casting, swaging or spinning process. In any event, the materials of the shank 1 and the diamond tool body will be of such character that the shank 1 will tighten sufficiently about the diamond tool for such frictional engagement as to permit rotary adjustment and dependable holding of the tool in such adjusted position without any other means for this purpose. One such suitable material for the shank 1 and for the diamond tool body is beryllium copper.
Thus, whenever it is desired to turn the diamond tool, this may be accomplished by means of a standard wrench applied to the polygonal surface 6 and without disturbing any other part or without requiring any other adjustment or the provision of any other mechanism. The present structure and arrangement of the parts is such that there will be permitted only rotary adjustment of the tool within its shank 1 and the tool will remain in the position to which adjusted until occasion requires such further adjustment. Also, the adjustment of the tool will be about the longitudinal axis of the same as the re-entrant portion of the tool is coaxial with respect thereto.
What I claim is:
1. The method of making a device for dressing grinding wheels or the like, consisting in providing a diamond tool with an integral re-entrant smooth surface co-axially thereabout, and applying a shank thereto by shaping a body of formable material about said diamond tool so as to effect a rotatably releasable frictional engagement therebetween.
2. A device for dressing grinding wheels or the like, comprising a shank adapted to be fixedly mounted at its one end within a holder for operation thereby and having an opening at its other end, the inner surface of said opening being provided with an annular inwardly extending portion, a tool carrying a diamond, said diamondcarrying tool having an annularly co-axially grooved integral portion in rotatably releasable uniformly frictional engagement with the inner surface of the inwardly extending portion within the opening in said shank.
3. The same structure as recited inclaim 2 hereof and in which said inwardly projecting portion and said grooved portion comprise interengaging middle cylindrical portions and diverging forward and rearward adjoining portions each in the form of a frustum of a cone.
4. The same structure as recited in claim 2 hereof and in which said tool has a co-axial cylindrical portion forward of said grooved portion and in engagement with said shank and in which said tool has a polygonal surface portion forwardly beyond said shank so as to permit application of a wrench thereto.
5. The same structure as recited in claim 4 hereof and in which said shank is in the form of an integral, onepiece body of material that engages co-axially about said diamond-carrying tool in a seamless manner and completely encloses the end of said tool that is opposite to the diamond.
6. The same structure as recited in claim 2 hereof and with the addition of a coating of lubricant between the frictionally interengaging surfaces of said tool and shank.
