TO L-l-iQLDER.
s: p. 's' ,4 1,"68,1l9. kapvclucllulol'l or Application filed Beccinher To all whom it may come Be it known that I, n ALTER Coonciuirr, subject of the King of Great Britain, residing at Philadelphia, in the county oi? Philadelphia and State of Peni'isylvania, have invented new and usetul linproven'ients in Tool-Holders, off which the following is a specification.
The invention relates to tools and more particularly to holders therefor, and has for an object to provide a holder for tools such as are generally used in machine shops and the like for cutting metal or other substances, the holder providing a rigid support for the tool when the latter is in use and permitting of changing from one kind or term oi tool to anot ier without necessarily necessitating the removal of the holder from its normal lit-Led position. turther obviating the necessity of removing the work from the lathe, chuck or other machine on which it may be carried.
In the further disclosure of the invention reference is to be had to the accompanying drawings constituting a part of this specification in which similar characters of ref erence denote corresponding parts in all the views, and in which,
Figure 1- is a side elevation of the tool holder showing the same in position for use.
Fig. 2 is a horizontal sectional view taken through the holder, parts of the shank being broken away.
Fig. 3- is a-view looking at the inner "face of the head, and
Fig. lis a view looking at a face of the enlarged portion of the shank.
Fig. is a plan view of a slightly inedified form.
Referring more particularly to the vi ws, the numeral designates a shank which at one end is formed into an enlarged portion 11 provided with a transverse threaded opening 12. The face 13 of the enlarged portion 11 has an elongated lug 1 iprojecting therefrom, the same being substantially in line with the diameter of the opening 12. Threaded into the opening 12 is a substantially tubular interiorly and exteriorly threaded nut 15, the threads on the inner face oithe out being smaller and therefore more to the inch than the threads on the outer face of the nut, the threads also differ: ing in that one is a right hand thread and the other a left hand thread.
A tool head 16 of an irregular but some- Lcttern .ttcnt.
what cruciform shape is provided, thus forniing projections 17 and notches 18, each pro ection being; provided with a squared opening 20 for the passage of a tool 21, set screws 22 being threaded into the projections 1'? at substantially rightangles to the passages 20, therein, so that the heads 23 ot the set screws will lie in the notches 18, the inner ends of the set screws engaging with the tools 21, extending through the pas sages, to lock the tools rigidly to the head. The inner face of the head is provided with a series of grooves 24: which are adapted to receive the lug 13. l Referring to the views it will be seen that different kinds or shapes of tools can be carq ried on the head if desired and that when the head is rotated different tool can be brought into operating position. It will be apparent that when the nut 15 is partially unscrewed from the enlarged portion of the shank, that this operation will simultaneously move the head away from the enlarged portion by reason of a reverse thread 25 on a stem 26 projecting from the inner face of the head and normally en aging with the internal thread of the nut and when the head is moved suiliciently away from the enlarged portion of the shank to clear the lug 13, ready rotation 01" the head can he obtained. By simply tightening up the nut 15 in the enlarged portion of the shank, the stem 26 of the head will recede into the nut drawing the head toward the enlarged portion of the shank and causing the lug 1.8 to he received in one of the grooves 24L, thus rigidly locking the head to the shank and securing the desiredtool on the head in position for operation upon the work at hand.
With this construction it will be apparent that the shank can be substantially held in the usual tool holder of a lathe or the like, while the head is manipulated to bring another tool into operating position and that in this connection the work to be operated upon can also he left in its position and need not necessarily he removed from the chuck of the lathe or work holding element. The provision of the opposed coarse and line threads on the nut and stem insure quick and ready movement of the head toward or away from the shank when moving the head into or out of locked relation with the lug on the enlarged portion of the shank and the comparatively few parts employed to bring about the desired construction provide for a' device that can be quickly and effectively handled and cheaply manufac tured to accomplish the desired result.
In Fig. 5 I show a slightly modified form in which each face 13 of the enlarged portion 11 of the shank is provided with an elongated lug 14 to cooperate with one of the grooves 2%- of the tool head 1.6 [Vith this construction the tool head can he mounted against either side of the enlarged portion or head of the shank so that the tool head is in fact reversible as to the part which holds up and looks it ri 'idly against movement.
Having described my invention, 1 Cl21i111- 1. A tool holder comprising a shank having a threaded opening, a lug projecting from the shank, an internally and externally threaded nut having the external thread thereof threaded into the opening of the shank, a tool holding head provided with grooves for receiving the lug on the shank to lock the head against rotation and a threaded stem projecting from the head to ing a threaded opening, a lug projecting from the shank, an internally and externally threaded nut having the external tln'cad thereof threaded into the opening of the shank, a. tool holding head provided with grooves for receiving the lug on the shank to lock the head against rotation. a threaded stem projecting from the head to engage with the internal thread of the nut with the thread on the stem. opposed to the external thread on the nut, insuring movement of the head toward or away from the shank when the nut is actuated, tools carried by the tool holding head and means for secur ing said tools rigidly thereon.
