' ADJUSTABLE SETTING-UP PIECE FOR TOOLS AND WORK LlIllCillS.

Application led September 6, 1927, Serial No. 217,770, and in Germany February 15, 192?.

lViy invention relates to an adjustable setting-up piece intended tor use especially in connection with tools and workpieces, but be* ing, besides, applicable everywhere where it is necessary to adjust objects vertically. n

hlore especially, the invention relatestoan adjustablesetting-up piece t'or lathe or turn- Cil ing tools and for similar tools. y It is known that the cutting edge ot said first-mentioned tools must be adjusted to4 a certain definite h yight relatively to the work-piece, and it is also o'lten times necessary to adjust the tool to a certain de'l'inite angle with respect to theV worlnpieee il the working oi the work-piece is to be exact, and too quick wear-and tea/rot the cuttingedge ot the` tool to be. prevented.y The tool boxes with segmentaladjustment as employed up to now for setting-up and adjusting` the tools suffer from the drawback that in the case ot an alterationoll the vertical adjustment ot the tool an alteration also ot the cutting angle takes place, so that the cutting edge is quickly worn ol'lion account ot its wrong angular position. -Also wedges which are shittable with respect to one another are .not suited as setting-up pieces for he tool, because Vthe wedges require very nectedwith another the thickness of whichy decreases uniformly.` or in a steplike manner. llVhen vthis cha1n-like member 1s used yas setting-up piece for a tool there is preferably arranged between this piece and the` tool a sejiiarate intermediate member, the upper au d lower surfaces o'lwhich decrease also, in thickness with respect to one another, the degree ot the decrease being the same as that ot the chain-like setting-up member propenso that if this member and said piece are placed one upon the other, in opposite direct-ions, the

uppermost surface lies horizontal, i. e. paral- Y lel to the surface oit the base. v i i The. invention is illustrated diag,rammatically and by way ot exaniple o n the accompanying drawing, on which Figure 1 is an end view and Figure 2 a side view of a tool carrier provided with a setting-up piece de-r signed according tov this invention; Figure. 3

Fig. 3 and shows amoditication, Figure 6 is a transverse section therethrough; Figureis a plan thereof, and Figure 9 is a'moditication olf` *Fig 8; Figures l() and ll yare alongitudinal section through, and a plan o'l', anothermodification; Figure l2 .is a longitudinal section through the separate lntcrn'iedrate member `already mentioned in the preamble, and Figf nected with each other, and Figure is a transverse section through Fig.,l4; in the vof another modilicatiou,Figure 8 a side view plane l-I oit' the same and drawn to an en-` slide which is located uponthe former and can be shifted thereon by means ola threaded` adjusting spindle 0., e denotes the tool carrier proper which is held in place upon the slide o by means ot a vertical bolt al and can be fixed by means oa nut f located on the top of said bolt. The holder e can be turned upon the bolt al and be liXed in any desired posit-ion. On the side counter to the said bolt the carrier proper e is provided with a horizontally j projecting ledge i el through which extend two vertical clamping screws ZL.

Below these screws is located upon the transverse slide 7) the chain-like setting-up piece ci, the upper and lower surfaces of which are inclined relatively to one another under a certain angle, as shown in Fig. 2, the entire piece 'al representing a kind of wedge. dcnotes the separate intermediate member which represents also a kind of wedge. .in F ig. S2 the piece i and the member 7c are arranged one above the other and in opposite directions, regards the inclin ati ou or obliquity, in consequence whereof the upper surface of the member -.e is horizontal. 'lhe tool m is supported directly by this member 7i' and firmly pressed upon it by the screws 71,.

If the position of height of the tool is to be altered, without any alteration of its hori- Zontal position, the screws L are loosened and the piece z' is then so much shifted as required for the other position of the tool, that is to say, the piece 71 is shifted either to the left t Fi g. 2) or to the right, according as whether the tool is to be lifted or lowered. The free ends of the piece 'i hang down, as shown, and do not hinder the workman in any way. It, under circumstances an unusually lon piece z' is required, its free ends may be rolled up or done away with in a similar manner so tl at the place they need is the smallest possible.

rlhe chain-like setting-up piece can be designed in various consti-notional forms, some of which are represented in Figs. 3 8.. In Figs. 3 and Ll the links n, of the setting-up piece are designed as hinge-halves; cach of them is provided on one of its long sides with a projection 01V and in the other of its long sides with a recess 02 receiving the projection V of the respective neighbouring link or hinge'- half, and the links or hinge-halves are movably connected with each other by pins p prevented, of course, from leaving their proper places.

In Figs. 5 and 6 the chain-forming parts nl are mov-ably connected with each other by a strap q located in bottom recesses r of the parts al and connected with these latter by rivets fw. The lower edges of the parts nl are preferably bevelled in order to permit the free ends of the setting-up piece to hang down, as in Fig. 2. Above the band g the abutting surfaces of `the links nl are preferably also somewhat inclined with respect to one another in order to attain that line chips entering, perhaps, into the joints do not prevent these latter from closing. The object of the recess r is to bring'about that the pressure. is transmitted directly by the links n upon the upper surface of the tool rest and the band Q is not compressed by this pressure.

In Figs. 7.and S the chain-forming parts are formed by small rollers nghaving axial bores through which pass pins p1 connected with each other by links s and S1.

The constructional form of the chain-.like setting-up piece shown in Fig. 9 corresponds essentially to the constructional form shown in Fig. 8, there lieing only the dill'erence that the rollers n? have flat top Afaces and tlat bottom faces, shown.

In Figs. 10 and 11 the setting-up piece consists of rectangular' cells n3 pressed, preferably, of sheetanetal and enclosing wedges u. Below these wedges are insertions o, the arrangement being preferably such that (for instance in the direction from the lett to the right, Figs. 1() and 1l) every following cell contains one insertion more than the cell preceding it whereby the. advantage is attained that all wedges can be of equal siyi. The wedges u., the insertions fu, and the cells n are preferably connected with each other, for instance by rivets w1.

The separate intermediate member shown in Figs. 12 and 13 is lx1-shaped in transverse section, that is tosay, it forms an inverted U, and the depth oft the bottom groove decreases from the .right to the lett. 'lfhe clear width of this `groove between the lateral boundary ledges /:l crufrespoiuls rpractically to the breadth of the chain-likesetting-up piece so that this latter is guided between said ledges, whereby lateralv displacement of the settingup piece is prevented.

rlhe separate intermediate member may be arranged loosely between the piece and the tool or it may be connected withv the same in any suitable manner. A suitable coi'istruc tional form is shown in Figs. 14e and 15 in which plate springs .e are atl'iiied to the lateral faces of the intermediatev pieces by screws t, for which latter other, e ulivalent, means may be employed. The upper faces of said sprin contact with the lateral surfaces of the tool m and hold this securely in place so that the tool is shiftably connected with the intermediate piece Zi. The advantage thereby obtained consists therein that Athe workman need handle only two parts instead. of three.

The 1li-19 show several possibilities of arranging the chain-like setting-up piece i ,and the separate intermediate member t, the intention in all these cases being` to `give the tool an oblique position, either upwardly, as in Figs. 1G and 17, or downwardly, as in 18 and In Figs. 17 and 19 the tool m is supported solely by the piece i, in Figs. 16 and 1S, however, by this piece, as wellv as by the member 7c, in which cases the obliquity or degree of inclination is greater than in the other case, in that both parts (the chainforniing setting-up piece. and the separate intermediate member) are inclined in the same direction. Y

In Fig. Q0 the upper surfaces of the individual parts n of the chain-like ,se ting-up member il are not inclined uniformly with respect to the lower siiihices, but the parts n are constructed in a step-like. manner in that the thickness of cach following part is greater or vice versa smaller than the thickness of misma:

the preceding part. In this case the interme-, (li-ate member 701. isvalso constructed in a stepylike fmanner thev height land the `length Aoff these steps being adapted. to the steps of thef and said member being equal,substantially chain-like member.y j

In Fig. 21 twosettmg-up members-i?, i2. of the kind illustrated in Fig. 20 are arranged aboveanother in opposite directions so 'that and 2l can be equal to the number of the individual parts of the chain-like member as shown in these figures. However, if desired, there may be provided a greater or smaller number of steps.

If the parts in question are arranged in the manner shown in `Fig. 2, that is to say, in such a manner that the tool is in a horizontal positionit is, of course of no consequence whether the superposed parts z' and c are arranged just as in Fig.,0 or if they are turned horizontally by 1800, the thinner end of the piece z' being then'on the right and that of the member 7c on the left. However the arrangement to be preferred is that in which the shorter free end of the piece z' is located next to the workpiece so that the free space on this side is obstructed as little as possible.

With the constructional forms of the invention, as illustrated on the drawings, the chain-like setting-up piece is arranged below the wedge It, but also the reverse arrangement is possible, that is to say, the wedge 7c may be arranged above thesetting-up piece in `which case the wedgeis preferably provided with a shoulder eith-er `at only one end or at both ends, the shoulder `or shoulders contacting with the front or the rear side of the tool rest or with both sides, as the case may be.
