'TOOL-HOLDER.
Specification of Letters Patent.
Patented une. `2, icio.
AppIication filed August 1.1I 1909. Serial No. 512,336.
To all whom it may concern:
. Beit known that I, Binner M. W. HANsoN, a citizen of the United States, residing at Hartford, in the county of Hartford vand State of Connecticut, have invented certain new and .useful Improvements in Tool- Holders, of which the following is a specilisation.`
This invention'relatesto tool-holders and a tool-holder ,comprising my-invention can be used with advantage in connection with various types of metal working machines although it is of particular adaptability in conjunction lwith a flat-top turret-lathe, the principal object of the invention being to provide. a tool-holder which can be rigidly and substantially secured to the turret by compact securing means. i
In the ldrawings accompanying 'and' form ing part of the present specification I have illustrated in detail one simple and convenient form of embodiment of the invention which to enable those skilled in the art to practice the invention will be set forth fully in the y following description while the novelty of the invention will beincludedin the claimsy succeeding said description. It
' will be understood that I do not restrict my- V throughout the several figures.
' As is well known the tool-holders in a lathe of the character to which allusion has been made, are sustained upon the upper surface of the Hat-top turret thereof and there are times when these tool-holders are disposed iii aiinular order or side by side. Usually the? old style tool-.holders have had lateral lugs 0r ears perforated to receive screws which are tapped into turret top. The prese ce of these side lugs or ears makes a very wi e tool-holde`r and one which naturally requires some. considerable lateral terial matter.
-ing through a space for its adjustment radially of said top. l provide 'a tool-holder wherein the defects pointed out are wholly eliminated and one which is stable and susceptible `of being I easily adjusted and inexpensively made.
y My improved tool-holder is designated in a general way by 5 'and it is preferably made in the form of a block which isu'sually made in the forni of a casting although this is not a matter of consequence. The under surface of said block is shown as being substantially rectangular although such shape is not a nia- The toolholder or block 5 Vis represented as having a tool-receiving chamber or passage as 6 extending completely through the same from front to rear although preferably the tool does not directly engage the wall of this chamber or passage the tool generally extending through a bushing or sleeve as 7 fitted into said chamber or passage G. Said bushing is shown as being of the t split l or divided type and-as -liaving a key-way 8 interiorly thereof at the bottom to receive a key on a tool (not shown).
The tool is passed through said bushing orl `sleeve S and the latter is then drawn or constricted about the tool in some convenient 'manner for example by a wedge-block as 9 disposed within the chamber '6 said block having two upwardly converging faces 9 which engage against similar faces 7 on the said bushing zit-opposite sides of the slot oi'. split of said bushing `by reason of which when said block 9 is forced down the bushing will be drawn about the tool to clamp the saine in-working position. Any desirable means may be provided for pressing the wedge block down l have shown twouscrews 10 for this purpose, they being tapped through the upper portion of the tool-holder or bloclc 5.l and their lower ends or tips engaging the block to attain the function in question. yThe wedge-block may be held from dropping ldown into the chamber 6 when the bushing 7 is removed by a screw 1l extending or threaded thereinto and projectperforation in the top of the tool-holder.
There areprobably several ways the toolholder 5y can be rigidly'connected with the turret-top 12. I have found that screws 13 answer the purpose satisfactorily and two of them are preferably provided they being screwed into tapped holes in the turret top and being located preferably at opposite sides of the front to rear central line of the tool-holder. These screws 13 are associated with the tool-holder in a novel and advantageous manner as will now appeal'.
The toolsholder 5 has at opposite sides thereof bores or countersunlr openings as 14 from which it will be evident that said bores are of two diameters and when I "speak of them as bores I do so in a general sense rather thanto convey the idea that they are made by a boring tool. lIn other Words these two openings may be made in various ways; nor is it essential that they be in two diameters although this form is advantageous in that the base portieri of the parts of the bores of greater diameter presents a solid and firm foundation for the heads of the screws utilized in clamping the tool-holder to the turret top 121 Said bores as will be obvious extend completely through the toolholder vdepthwise thereof and the screws 13 to which I have referred can be passed toward their seats through the upper open tops of said bores,whi0h extend as shown vertically but which would not be so disposed were the tool-holder horizontally arranged. These bores as will he evident intersect the'tool-receiving passage the preferable though not essential relation, such relationbeing the preferable one because greater compactness is secured than if said bores were disposed outside of or at opposite sides of said tool-receiving passage or chamber 6; in the latter event the width of the toolholder would have to be increased. By referring to Fig. l it will be seen that the smaller portions of said bores are located below the tool-receiving chamber or opening of the tool-block. It thereforeA is obvious that I can provide a tool-holder somewhat narrow in construction and this without weakening in anywise the device.
When the position lof the tool-holder is to be changed it is a simple matter to introduce a socket-wrench into the bores 14 and remove the screws 13 which are shown as being setin Figs. 1 and 2. YV ith kthe screws out the-tool-holder `will be moved radially of theturret top until the desired adjust ment has been obtained at which time the wrench previously used will be called into lrequisition and the screws passed into said bores and their Shanks passed through the smaller diametrical portions of said bores into the threaded seats of the turret top 'when said screws will be run'home until the tool-holder is properly clamped in place, the heads of the screws as intimated .binding against the bases of the larger diametrieal portions of said bores. The heads of the screws lll are therefore inclosed by the toolholder.
What I claim is:'
1. A tool-holder having a tool-receiving passage extending from front to rear ther lof and a bore having different diameters, for the passage of a screw, intersecting said parsa-ge and extending entirely through said tool-holder from top to bottom thereof.
2. A tool-holder having a tool-receiving passage extending' from front to rear thereof and als/o having bores having different diameters laterally separated and both intersecting said passage said bores being adapted for the passage, respectively, of clamping screws and extending entirely through said tool-holder from top to bottom thereof.
A tool-holder having tool-receivin passage extending from front to rear thereo and also having a bore .for the passage of a screw, intersecting said-passage and of two diameters, said bore extending entirely through said tool-holder from the top to the bottom thereof.
4. A tool-holder having a. tool-receiving passage extending from front to rear thereof and also having laterally-separated bores of different diameters extending entirely through the same from to to bottom thereof and also intersecting said passage.
5. The combination of a turret top, a toolholder supported on said top, and screws inclosed by the tool-holder, for clamping said tool-holder to said turret top, the heads of the screws being located below the upper surface of said tool-holder.
6. A tool-holder having a tool-receiving passage extending entirely through the same rom front to rear ythereof and also having laterally separated bores extending from top to bol tom thereof, each of said bores being of different diameters, the portions of lar e diameter intersecting said passage and tige 4portions of small diameter being located re'- speetivelybelow the portions of larger di"- ameter.
In testimony whereof I affix my signature in presence of two witnesses.
