QHABLES LESLIE NEWLAND, F ELTHAM, ENGLAND.
.mcHmE-roon 110mm.
To all? whom it may concern."
Be it known that I CHARLES DEsLInNEW- LAND, asubject of His Majesty the 'Klllg of Englandandre'sideht of Eltham, in the cation,
This invention relates to'turret tool holders of the kind in which thetools are peripherally arranged in a holder adaptedto be.
rotated so as to b'ring the several tools into operation when. desired, the holder be ng clamped in a split ring and the tools being maintainedfin the operativeposition l' by a spring-pressed pawl. I The present. invention has for its object to provide animproved construction of tool holder of the aforesaid type.
According tothe present; invention a multiple tool holder of the, aforesaid type is adapted to carry a set'of tools projecting from the face thereof; the said tools being intended but not limited to use for interior work. The tool holder is preferably formed" with an integral ratchet adapted :to cooperate with an adjustable pawl directly engaging the ratchet wheel" at one end and subjected to the action of a spring at the other end so as to prevent rotation of the ratchet wheel and tool holder unless in the desired direction; Theholes to receive the facially-disposed tools extend the entire width'of the tool holder and ratchet wheel;
The tools are interchangeable and inter changeable means are providedjto lock the tools in the operative position.'g'An opening is provided axially of the tool holder and extends through the entire width thereof and the ratchet wheel.
I will describe with reference to the accompanying drawing a construction in accordance with the present invention but I do not limit myself to the precise details of construction described and illustrated.
Figure .1 is a side elevation of a machinetool-holder in accordance with the present invention, part thereof being shown in section. V
Figure 2 is a plan of Figure 1 showing the tool-holder as used for outside and in side work.
; Specification of Letters Patent.
Patented Feb. 7, 1922.
Application filed April 15, 1920. Serial No. 374,168,
Figure 3 is a cross section on the line A.A Figure .2.
Figure 4 is a section on the line BB. Fig I ure looking in the directionof the arrows' Fi'g. 5 1s a detail side view ofaportion of the device. seen in F ig. 2.
Referring-to the drawing the bar 1 herelnbefore referred to isformed with or has permanently or removably attached theretoa split ring 2 capable of being contracted by a screwed pin 3 or equivalent so as to grip or bind on a rearwardly projecting .portion 4 of the rotatable member 5 and holdthe same locked in the desired position.
The rotatable tool carrying member is preferably provided with a reduced part 4 which is hereinafter referred to as the rear part and is engaged by the split ring 2. The
outer or forward portion 6 of the rotatable member 5 is provided with a plurality of radially arranged holes 7 into each of which a tool can be pushed one of which is shown at 8 and retained therein by locking pins 9 disposed concentrically of the axis of the rotatable member and being preferably manipulated into and out of locking position from the rear face of the reduced portion of the rotatable member.
concentrically arranged relatively to the axis of the rotatable member and extending through or for any desired distance into the said member are a plurality of holes 10,' slots or grooves each capable 'ofcarrying any desired tool such as shown at 11,which can belocked in position by set screws 12 radially arranged with respect to the rotatable member 5- and capable of being screwed into locking position against the respective tool. r
The rear end 4 ofthe reduced portion of the rotatable member is provided with a plurality of teeth 13 corresponding in number to the number of tools which can be carried by the rotatable member 5. Co-operating with the aforesaid teeth which may be in the form of shallow ratchet teeth is a spring pressed pawl 14 mounted preferably in a recess 15 in the carrying bar 1 and adapted by. a screw 16 or equivalent to be adjusted or raised or lowered relatively to a central po sition so as to vary the operative position b of the rotatable member 5. The rotatable member carrying the tools is free to rotate direction of the arrow D Figure 1 because of engagement of the spring pressed pawl 14 with one or other of the ratchet teeth. The spring pressed pawland ratchet wheel provide a ready means for adjustment of the height of the tool relatively to the centre of the work which adjustment is easily and quickly effected. Lateral displacement of the rotatable member may be avoided by providing the reduced portion with a-peripheral groove 17 or recess and a set pin 18 adapted to be screwed through the split ring 2 into engagement with the said peripheral groove or recess 17.' 7
The central portion of the rotatable member may be hollow to receive a bar having a screwed end disposed eccentrica'lly of the bar and adapted to receive a chuck as shown in. Figure. 4, wherein 19 is the bar above re- V ferredto and 20 a chuck of knowntype having split'jaws to receive a tool shank.
The tool-holder may be used in the horizontal position as shown in Figure 5 in which position the tool is turned through an angle of ninety degrees relatively to the po sition shown in Figure 2. In Figure 5 the relative position of the tool and the work I are shown.
The rotatable member may be arranged and adapted to carry four or other suitable number of peripherally arranged tools or exterior cutters, and four or other suitable number of facially arranged tool or interior cutters and the tools are preferably of the circular form with or without a fiat side or The heads of the various locking pins as also the head of the split clamping pin are squared and are allof the same size so that heads of the locking pins and the clamping pin.
That I claim is :I 1. A multiple tool holderfor metal work one box key or manipulating key fits all the ing machines comprlslng an arm having'a disposed'concentrically therewith, a plurality of facial tools mountedsin holes. 'disa I:
posed parallel .to the 'airis of the tool carrier and means toclamp the said tool carrier. and ratchetwheel in operative position, and.
concentrically arranged therewith,
meansto adjust the'ratchet wheel circularly so as to adjust the height of the jtoollrelativelyto the work.
2. A multiple r001 holderjformetalwork- 1 ing machines comprising an arm having a split bearing at one end, a hollow cylindrical casing having. radially arranged holes'therethrough and a reduced portion formed as aw ratchet wheel adapted to be frotatably clamped in position inthe split bearing, a
plurality of holes in the hollowleylindrical Y i casing disposed parallel to. the" axis of the said casing and concentric therewith, means 7 K adapted to prevent circular displacement of the ratchet wheel and tool carrier and also to allow of adjustment of thetool carrier,
and means to prevent longitudinal displacement of the toolcarrier'. I
3. A multiple tool'holder comprising arm having a split bearing at one end, a tool carrier'rotatably mounted therein, a ratchet wheel formed integral with the tool carrier, an axial bore through the tool carrierfand ratchet wheel, tool-receiving radial holes spaced round the tool carrier, longitudinally disposed tool receiving holes through the tool carrier and ratchet wheel and concen-v trio with the axis thereof, a spring-pressed pawl located in a recess in the tool carrier armfmeans to adjust'the said pawl, and
means to retain the tool carrier and ratchet wheel'in the split hearing when :unclampedv therein.
