Description
March 17, 1936.; H. WIENER TOOL HOLDER Filed April 25, 1934 Inventor Patented Mar. 17, 1936 UNITE STATES OFFICE 1 Claim.
This invention relates to a tool holder, the general object of the invention being to provide a holder with which a plurality of difierent types of bits and cutters can be used, with means for adjustably and detachably connecting the holder to a shank or supporting. member.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.
In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:
Figure 1 is a. vertical sectional view showing one form of the invention.
Figure 2 is a top plan view of Figure 1, with parts broken away.
Figure 3 is a View of the inner end of the holder.
Figure 4 is a plan view of the head of the shank, with the holder removed.
Figure 5 is a view similar to Figure 1, but
showing a. modification.
Figure 6 is a top plan view of Figure 1. In this drawing, the numeral I indicates a shank which is provided with a head 2, said head having a vertically arranged substantially T- shaped opening 3 therein which passes from the upper face of the head through the lower face and having its front opening out through the front face of the head. A vertically arranged substantially semi-circular groove 4 is formed in the rear wall of the opening and a substantially semi-circular key 5 extends into the central part of the groove, as shown more particularly in Figure l. The holder is shown at 6 and the front part of this holder has an opening I therein which extends from one side face of the holder through the other side face and opens out through the front face and the bottom wall of this opening has a keyway 8 therein which extends the full length of the opening and is equally spaced from the rear wall of the opening and the front wall of the holder. A pair of threaded holes 9 extends from the upper face of the holder through the top wall of the opening for receiving the screws or bolts III which act to hold the bit or cutter in the opening 'I. As will be understood, the base part of the bit snugly fits in the opening I and has a centrally arranged rib there- 55 on for entering the keyway 8 so that different kinds and types of bits and cutters, all made from similar stock, may be used with this holder,
as it is simply necessary to use stock of a size to fit in the opening I and having a centrally arranged n'b thereon for fitting in the keyway 8. 5 This holder will also permit left and right hand bits and cutters to be used therein and a number of the bits or cutters can be used at the same time. For instance, two outer bits and a central bit can be placed in the opening I, the screws 10 being used to hold the outer bits in position and these bits will hold the central bit in position.
The holder 6 is formed with a T-shaped part I I which fits in the T-shaped opening 3 and the rear wall of this T-shaped part I I is formed with a sub- 1 stantially semi-circular groove I 2 therein, spirally threaded, as shown at I3, and a spiral shaft I4 is placed in the circular bore formed by this groove I 2 and the groove 4, with its threads engaging the threads I3 of the groove I2. This shaft is formed 20 with an annular central groove I5 in which the key 5 fits so that this key acts to hold the shaft in position, while permitting it to be rotated so as to raise and lower the holder 6. The upper end of the shaft is formed with a wrench receiving socket 25 I6 so that it can be rotated by a wrench. An elongated slot I1 is formed in the reduced part of the T-shaped portion I I and a bolt I8 passes through this slot and through holes in the head 2, one of the holes being threaded, as shown at I9 in Figure 30 2, toreceive the threaded end of the bolt. This bolt acts to hold the holder in position, while permitting it to be raised and lowered by the screw or shaft I4.
One side edge of the T-shaped part II of the holder 6 is formed with a recess 20 having a stepped inner wall 2I for engagement by a set screw 22 passing through a threaded hole in the head 2, this set screw holding the holder I I in adjusted position after it has been adjusted by the turning of the shaft I I.
In the modification shown in Figures 5 and 6, the holder 6 is adapted to be adjusted vertically by hand and is held in adjusted position by the set screw 22 engaging a stepped wall of a recess formed in the T-shaped part, as explained above.
In other respects, this form of the device is similar to that before described.
From the foregoing, it will be seen that I have provided a holder which can be used with a large number of different kinds of bits and cutters, with a shank or supporting member in which the holder can be adjusted vertically and the holder can be r moved from the shank and another holder substituted therefor, the substitute holder being used for holding a drill or boring bar. By providing means for raising the holder, the life of the bits is extended, as the bits can be used even after they have been ground below center.
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.
What is claimed is:-
A device of the class described, comprising a shank having a head at one end thereof, said head having a T-shaped opening therein, the stem forming part of which opens out through the front face of the head and the rear wall of said opening having a substantially semi-circular groove therein extending from one face of the head through the opposite face, a substantially semi-circular key in the central part of said groove, a holder having a T-shaped part slidably arranged in the T- shaped opening, the rear wall of the T-shaped part having a substantially semi-circular groove therein formed with spiral threads, a screw shaft passing through the opening formed by said grooves and having a centrally arranged annular groove for receiving the key, whereby the screw shaft is held against longitudinal movement, one side edge of the head of the T-shape part of the holder having a recess therein, the bottom of which is stepped with the steps gradually increasing in depth from the top step to the lower step and a set screw passing through a threaded hole in the head with its inner end adapted to engage a stepped part for holding the holder in adjusted position in the head.
