To all whom t may concern:
Be it known that I, ALEXANDER A; Gn-
nrcnn, a citizen of the United States, residing at Detroit, in the county of Wayne and patate of il/lichigan, have invented certain new and useful improvements in Adjustable Dies, of which the following is a speciiication.
This invention relates to dies for cutting threads upon rods or tubes and has for its object the provision of a die'which may be readily adjusted to the diameter of the'rod ortube which is to'be threaded. The invention also seeks to provide a die which will be simple in construction and in which the parts will be compactly arranged and- Fig. 3 is a transverse section taken on the line 3 3 ofy Fig. 2; j
Fig. 4 isa perspective view of yone-of the cutters.
In carryingout my inventioml employ a base or socket member consisting of an annular rim or collar 1 having a diaphragm 2 at one end. This. diaphragm has a central opening 3 of a diameter suiicient to accommodate the maximum diameter of rod upon` which the die may be used and extending outwardly from the said central opening are a plurality of'radially disposed notches or open-ended slots t. The externalsurface of the rim or collar 1 may be smooth or may be knurled or otherwise treated but the interior surface of said collar is threaded, as'
shown at 5, to be engaged by the external threads 6 of a clamping member 7 which is preferably in the form of a circular disk or web having a central opening and provided with a hub or circular projection 8 upon one face, the external periphery of the hub being knurled or otherwise treated, as shown at 9, whereby it may be firmly grasped by the hand of the operator. The central opening throughl the hub portion of the clamping member is threaded for a purpose to be presently set forth but in the body7 portion of the clamping member the` cent 1al opening is provided with a smooth wall, which is flared, as shcwn at 10, toward the inner end cr face of the body member whereby it is adapted to ride over the cutters and move the same ra*- dially of the base me ber so that they wiil be properly set to engage the work. The cutters 11 substantially three-sided blocks, two sides or ends 12 of the blocks being iat and disposed apj'iroximately on radii of the base member, while the third side is arcuate so as to conform to the arcuate surface of the chamber l() in the clamp- "'f ing memberand also inclined or tapered to correspond to the flare of the wall of said chamber. The apex-,or meeting corner of the flat ends or sides 12vof the cutter is cut away 'and dished, shown at 13, sharp threads or cutting surfaces le being'fcrmed upon the said dished face 13, as clearly shown. These cutting teeth or threads will be of the same pitch or size in all the cutters of a given set and when a pipe or rod is to be threaded the set of ycutters having the required 'pitch or size of thread will be placed within the base member of the die. 'if he end faces of the cutter, as shown at 15 and 16, are flat and disposed in planes at a right angle to the aXisof the die, the larger face v15 setting'against'the inner surface Vof the web 2 and being constructed with 'a radial lug 17 to fit within ythe proper notch or slot et and slidabiy engage the same so as to guide the cutter in its adjustment. The face 16 of the cutteris free of projections so that it may be engaged by the end wall of the chamber 10 and by the end of a locking screw o sleeve 1S which is threaded through the hub member '7, as clearly shown inFig. 2, the projecting end kofthe said locking vsleeve or screw being knurled or otherwise treated, shown'at 19, whereby it may be firmly grasped by the operator.
It is thought the construction and arrangement of the several parts of the device having been` thus set forth, the operation of the vsame will be readily understood from the accompanying drawings. The base member is placed upon a table or other fiat surface with the open end of the rim l uppermost. The proper cutters are then inserted in the base member with their projections or lugs 17 fitting within the respective slots or notches 4 of the web 2, after which the clamping member 7 is inserted in the upper cud of the ring' or collar l and engaged therewith. Any convenient form of gage rod may then be inserted between the cut ters so that if the cutters be moved inwardly to engage around the said rod they will be set to the diameter of the rod or pipe which is to be threaded. rl`he clamping member is then rotated so that it will ride downwardly in the ring or collar l and as it `thus rides downwardly the central .flared chamber thereof will engage. the inclined outer surfaces of the cutters andleff feet a wedging engagement therewith so :is to for/'e them radially toward the center of the die. When Jthe cutters have been thus caused to bear against the gage rod the fi'lrther rotation of the clamping body may cease and the gage rod be withdrawn. 'l'he locking sleeve 18 is then rotated so that it will ride inwardly through the hub Si and bring its inner end to bear upon the inner faces of the several cutters. lVhen this locking' sleeve has been turned home against the cutters it will effectually bind them against the web 2 so that they will be locked in their adjusted positions and the die, therefore, set for use. The die may then be used in the usual manner and will cut the threads readily without any liability of the cutters slipping while in use. Should it be necessary to adjust the dies before the threads are completely formed so as to deepen the` previously made cut, the locking sleeve is slightly released after which thezuljusting` body 7 `is turned so as to move the cutters slightly inward after which the locking" sleeve is again turned home. i
My device is obviously simple in thereonstruction and arrangement of its parts and a minimum number of parts is employed. The cutters can be quickly and easily adliusted to the diameter of the work and after being' set for the desired work will be 'firmly held so that they will not slip while in use.
The die can be held in any standard diel holder and can be operated manually or invention,
plurality of cutters .fitted in the base member for movement radially thereof, an adjusting membenfitted inthe base member for movement longitudinally of the same and adapted to engage the dies and effect radial movement thereof, and means fitted in said adjusting member to lock thecutters in their set position.
2. Vdie 'comprising a socket member,
.witlrguides slidably vengaging;- said notches,
an adjusting' member mounted in the socket memberand engaging the vcutters to effect radial movement thereof, and means carried by said adjusting member to lock the cutters in a set position. y
e. A-' die comprising a socket member, a plurality 'of cutters fitted within `the socket member for radial movement and having' tapered outer surfaces, an adjusting disk rotatably fitted` within the socket member and movable longitudinally thereof and provided with a central flared chamber Vto engage the outer tapered surfaces of the cutters whereby to effect radial movement ofthe cutters, and means carried bylsaid adjusting-j member to .lock the cutters ina set position. Y
