TOOL HOLDER Filed July :51, 1939 INVEIVTCR. George Wa/zms/z Patented May 6, 1941 UNITED STATES PATENT OFFECE TGOL HQLDER George Wahnish, Los Angeles, Calif.
Application July 31, 1939, Serial No. 287,616
4 Claims. 01. 29-96) My'invention relates to a machine tool holding means, more particularly for a means for holding parting tools used to cut off or part Work in lathe centers and the objects of my invention are:
First, to provide a means for compensating for the variation size and thickness of machine tools of this class;
Second, to provide such a means that always supports tools so that its cutting point is always in alignment with the axis of the work;
Third, to provide a means of this class by the use of which machine tools of. the class described may be held securely in their proper position to provide the highest efficiency;
Fourth, to provide a means of this class by the use of which varying tools may be quickly and effectively secured in proper operating position relatively to the work;
Fifth, to provide a means of this class which is applicable for use in connection with the conventional supporting member, conventional tool and clamping bolt;
Sixth, to provide a novel means for compensating for the support of various size tools of this class; and
Seventh, to provide a means of this class which is very simple of construction, easy to operate, e ficient in its action and which will not readily deteriorate or get out of order.
With these and other objects in View as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawing and to the characters of reference thereon which form a part of this application in which:
Figure 1 is a fragmentary side elevational view of my machine tool holding means; Fig. 2 a bottom view taken from the line 2--2 of Fig. 1; Fig. 3 a sectional view taken from the line 3-3 of Fig. 1; Fig. 4 a similar view showing a larger tool and larger compensation member; Fig. 5 a perspective view of the compensation member and Fig. 6 a similar view showing a larger compensation member to be used with a smaller tool.
Similar characters of reference refer to similar parts and portions throughout the several views of the drawing:
The main tool supporting member I tool member 2, variation compensation member 3, and bolt 4 constitute the principal parts of my machine tool holding means.
The main tool supporting member I may be of any conventional type consisting of a shank portion la and a head portion lb, the shank portion la. being positioned on an angle to the head portion lb so that the head portion lb has an offset portion lc extending along one side thereof. In this offset portion la is provided a semi-dovetail slot Id; as shown best in Figs. 3 and 4 of. the drawing provided with an inwardly tapered portion le. Mounted at the other side of the slot ld and centrally of the head I is a bolt 4 which is provided with a tapered head 4a and with a slot 4b substantially the depth of the slot Id when the bolt is positioned rigidly in position as shown best in Figs. 3 and 4 of the drawing. This bolt is secured in position by means of a nut 40. Mounted in this semi-dovetailed slot Id and adapted to fit at one side in the slot 42) in the bolt 4 is my variation compensation member 3 which is shaped at two of its sides to fit in the slot Id and against the tapered side le of said slot as shown best in Figs. 3 and 4 of the drawing. It is provided on its opposite side with a semidovetail slot 3a with a tapered end 3b which conforms to the one side of the conventional tool 2. The one shown is a conventional parting tool.
The opposite side of the tool 2 from the side 3b rests in the slot 4b in the bolt 4 in alignment with the compensating side 30 of the compensation member 3 as shown best in Figs. 3 and 4 of the drawing so that the bolt 4 wedges and clamps the members 2, 3 and l rigidly together forcing them into the dove-tailed portion of the members I and 3, thus rigidly securing them in position, and it will be noted that these members 3 compensate for the variation of thickness of the tools 2 as shown best in Figs. 3 and 4 of the drawing and are made of varying sizes to compensate for this thickness, as shown in Figs. 5 and. 6 of the drawing. Thus varying size tools 2 may be readily secured in the proper position at the proper relative position to the work by this compensation member 3.
It will be here noted that the members I, 2 and 4 are of conventional type and that applicant has added to the combination the variation compensation member 3 which is properly shaped and formed to properly support the tool in position relatively to the work regardless of the varying size of the tool to be supported.
The operation of my machine tool holding means is substantially as follows:
The main tool supporting member I is supported in the proper position on the lathe to cooperate with the work. Then a proper size tool is selected for parting the material. Then a proper size variation compensation member 3 is selected to fill the space between the tool 2 and the portion lb in the slot Id. The tool 2 and the compensation member 3 are then placed together and slid into the slot Id and in the slot 41) in the bolt 4 as shown best in Figs. 3 and 4 of the drawing and they are slid into position ready for operation with the point of the tool in proper relation with the work. Then the nut 40 is tightened on the bolt 4 clamping the members in their proper position, as shown in Figs. 3 and 4 of the drawing, with the tool 2 extending past the members I and 3 as shown best in Figs. 1 and 2 of the drawing and the machine tool holding means is ready for operation.
Though I have shown and described a particular construction, combination and'arrangeinent of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In a machine tool holding means of, the class described, the combination with a main tool supporting member provided with an inwardly tapered recessed portion and a tool member provided with a beveled side, of a variation compensation member provided with an inwardly tapered recessed portion and a beveled outer portion shaped and arranged to conform to the tapered recessed portion of said main tool supporting-member and beveled portion of said tool member to fill the space between said tool member and the main tool supporting member head.
2. In a machine tool holding means of the class desoribedthe combination with a main tool supporting member provided with an inwardly tapered recessed portion and a tool member provided with a beveled side, of a variation compensation member provided with an inwardly tapered recessed portion and a beveled outer portion shaped and arranged to conform to the tapered recessed portion of said main tool supporting member and beveled portion of said tool member to fill the space between said tool member and the main tool supporting member head, and a bolt transversely of said variation compensation member and said tool member provided with a beveled head and a slot adapted to receive said tool member and one side of said compensation member and arranged to clamp said tool member, said compensation member and main supporting member head rigidly together.
3. In a machine tool holding means of the class described, the combination of a main tool supporting head provided with a semi-dovetailed slot therein, a variation compensation member with two sides conforming to said slot and adapted to fit therein, said compensation member provided with a semi-dovetailed slot therein and a tool member provided with a beveled side adapted to fit the semi-dovetailed slot portion of said variation compensation member.
4. In a machine tool holding means of the class described, the combination of a main tool supporting head provided with a semi-dovetailed slot therein, a variation compensation member with two sides conforming to said slot and adapted to fit therein, said compensation member provided with a beveled side adapted to fit the semi-.
v dovetailed slot portion of said compensation memher, a tool member provided with a beveled side 7 adapted to fit the semi-dovetailed slot portion 5 of said variation compensation member and a
