5 1y to'such gauges for guiding in the orientation of thread-cutting chasers or dies of circular form. One of the objects of the present invention is to provide a superior gauge of the class described, which will serve for the orientation of circular chasers of various characteristics.
A further object is to provide a circular-chaser gauge which may be conveniently converted for orienting either rightor left-hand chasers.
With the above and. other objects in view, as will appear to those skilled in the art from the following, considered in conjunction with the accompanying drawings and appended claims, the present invention includes all features disclosed therein which are novel over the prior art.
In the accompanying drawings: a
Fig. 1 is a perspective view of one form which a, circular-chaser gauge may assume in accordance with the present invention;
Fig. 2 is a top orplan view thereof with a circular chaser and its mounting-member shown in place;
Fig. 3 is a side view of the gauge;
Fig. 4 is a view thereof in end elevation;
Fig. 5 is a transverse sectional view taken on the line 5-5 of Fig. 3, but also showing in broken lines a circular chaser together with its mounting-member; and
. Fig. 6 is a perspective view of the carrying slide.
The particular circular-chaser gauge herein chosen as illustrative of the present invention includes a base-block l having a groove II in its upper face, extending from end to end thereof, and designed for the reception of the tang 12 of a chaser-mounting member l3, indicated by full lines in Fig. 2 and by broken lines in Fig. 5. 'The chaser-mounting member carries on its upper face a. circular chaser l4 secured to it with capacity for being turned with respect thereto by a stud l and a nut I6, as indicated in Fig. 2. The circular chaser I4 is of substantially-cylindrical form, save that it is cut away on one side to provide a cutting-lip I7, and has its periphery formed with substantially-annular helically-inclined cutting-teeth I 3. i
It may be explained in this connection that as the chaser [4 becomes dull, it is removed, together with its mounting-member l3 from the die-head or other tool in which it is used, and it is resharpened by grinding back its cuttingmicrometerlip II. This grinding of the cutting-lip, as just described, disturbs the orientation thereof with respect to the mounting-member, and it is for the purpose of enabling the cutting-lip to be accurately repositioned or oriented with respect to the said mounting-member that the present gauge is mainly designed.
The tang it of the chaser-mounting member l3, after having been inserted in the groove I l in the base-block It], is slid into position to en: gage that portion of the periphery of the chaser M lying adjacent its cutting-lip H with an abutment in the form of an abutment-pin or stoppin it, after which the mounting-member is clamped in place in the base-block It) by means of a clamping-screw 20, which is threaded into the most appropriate one of six (more or less) corresponding threaded bores 2|, three of which extend through each of the side-walls of the base-block so as to intersect the groove 1 I therein.
The stop-pin or abutment l9 oiTsets from the inner face of a bar-like elevatorslide 22 sliding in a vertical guide-way 23 in the adjacent face of the base-block iii and clamped in any desired position of vertical adjustment therein by a socket-headed clamping-screw 24 extending through a vertical slot 25 in the said elevatorslide 22 and into the said base-block.
Adjacent its upper end, each of the respective opposite edges of the elevator-slide 22 is provided with a horizontal guide-groove 26, either of which may receive, as desired, a horizontal micrometer-carrying slide 21, adjustable in a direction parallel with the slot ii in the baseblock ID by means of' an adjusting-screw 28 threaded into the adjacent one of two corresponding threaded bores 29-48, respectively located in the elevator-slide 22 adjacent the respective guide-grooves 2626 therein. The adjusting-screw 28, just referred to, is provided with an annular flange 3B fitting into a notch 3| in the under face of the adjusting-slide 21 adjacent the outer end thereof and serving to couple the said adjusting'screw to the said slide for effecting the longitudinal adjustment of the latter by the former. After a suitable adjustment of the slide 21 has been effected, the same may be firmly locked in place by a socket-headed screw 32 passing through a longitudinal slot 33 in the said slideand into a threaded bore 34 extending through the elevator slide 22 from one of the guide-grooves 26 on one side thereof to the other of said guide-grooves.
The inner end of the micrometer-carrying slide 21 mounts a removable micrometer, generally designated by the numeral 35, having a point 36 and clamped in the said slide with capacity for being bodily removed therefrom by a clamping-screw 3i (Figs. 1 and 2).
After the periphery of the chaser has been engaged with the stop-pin E!) as hereinbefore described, the micrometer-carrying slide 21 may be slid longitudinally by the adjusting-screw 28 until its point 36 is in substantial alignment with the root of the threads it, where the same break through the cutting-lip ll. It is the desired practice to align the point 35 of the micrometer 35 with the root of the uppermost one of the threads E thereon, and since chasers are apt to vary in height, the micrometer may be raised or lowered as desired, by loosening the clamping-screw 24 and moving the elevator-slide 2 vertically as desired, which thereby effects the vertical adjustment not only of the micrometer 35, but concurrently effects the vertical adjustment of the stop-pin is.
After the parts have been set, as above described, the micrometer is adjusted to indicate the desired measurement, and the chaser M is turned upon its stud l5 until the face of the cutting-lip l'l adjacent the root of the outermost thread 88 engages with the previouslyadjusted point 36 of the micrometer. The chaser, after having thus been accurately oriented in accordance with predetermined measurements, is firmly clamped to its mounting-member l3 by tightening the nut Hi. The clamping-screw 253 may now be loosened and the chaser, together with its mounting-member, removed from the gauge and installed in its intended die-head or other suitable device.
In the event that it is desired to orient a circular chaser having a cutting-lip ll facing the opposite direction from that shown in Fig. 2, the device may be readily converted by removing the micrometer-carrying slide 2? from the righthand guide-groove 25 in the elevator-slide 22 and placing the same in the complementary lefthand groove thereof. The adjusting-screw 23 is correspondingly shifted from the right-hand one of the threaded bores 29 to the left-hand one thereof. The micrometer is released from the slide 2'! by loosening the screw 31 and is reversed in position so as to project over the groove ii in the base-block it from the left side thereof. The procedure for orienting a lefthand chaser may now be carried out in the same manner as in the right-hand chaser, as before described. Incidentally, it may be mentioned that when the above rearrangement of the parts is made, the clamping-screw 20 is also reversed from the rightto the left-hand side of the base-block I El in the most convenientl positioned one of the threaded bores 2!,
From the foregoing, it will be seen that the gauge may be conveniently adjusted for orienting circular chasers of various heights, thread depths, etc., without disturbing the relative vertical positioning of the stop-pin l9 with respect to the point 36 of the micrometer 35.
The invention may be carried out in other specific ways than that herein set forth without departing from the spirit and essential characteristics of the invention, and the present em bodiment is therefore to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
