This invention is a handle for use on inside micrometers and similar instruments and is especially adapted for holding a micrometer in proper position in the bore of an engine cylinder, or in any other similar orifice, the diameter of which it is desired to accurately measure.
By means of 'the handle the instrument is held in place while the operator makes the usual adjustments of the micrometer.
The objects of my invention are, to provide a removable handle for inside micrometers and other articles that have to be used in places, such as engine cylinders and the like, where the operators hands can not easily reach. The characteristics of the handle are, absence of projecting parts, tightness of grip, to hold a micrometer rigidly to the handle and at right angles to it, simplicity of construction and ability to be tightened or loosened from the free end of the handle.
"With the foregoing and certain other objects in view, which will appear later in the specifications, my invention comprises the devices described and claimed and the equivalents thereof.
Fig. 1 is a view of my invention used as a handle for an inside micrometer.
Fig. 2 is a partial side view of the device without the micrometer.
Fig. 3 is a side view of the flexible looped ta e.
IFig. 4l is a front view of the parts shown in Fig. 3.
Fig. 5 is a part sectional detail, showing the construction of the lower end of the tubular handle.
Fig. 6 is a part section on. line 6-6 of Fig. 5.
As is shown in Fig. 1, the device is adapted to be attached as a handle to an instrument, say, an inside micrometer l, to enable it to be inserted into a chamber 2 or bore ofa pipe or cylinder, the inside diameter of which is to be measured.
The handle 3 is tubular, and one end is bifurcated and spread to provide a pair of angularly disposed jaws e. Each of said jaws has on its inner face a pair of parallel, spaced, work-engaging ribs 5, the space between the ribs of each jaw defining a` channel or groove 6 for the reception of a tape, the purpose of which will now be explained. When the jaws are set astride the barrel of a micrometer, as inFig. 1, the ribs 5 rest on the barrel, and the channel 6 and the face of the barrel define a slit through which passes a thin looped metallic tape 7 that partly encircles vthe barrel of the micrometer. The tape rides between the ribs 5 shown inFigs. 5 and 6,.which act as a sort of guide for it. The bearings of the ribs upon the micrometer barrel being outside the tape, wabbling of the micrometer is prevented and it is always held perpendicular to the handle. The ends of the tape are secured to an end of a rod 8 that extends lengthwise of the tubular handle and is adjustable longitudinally therein. The other end of rod 8 passes through a hole in the free end of handle 3, and is threaded to receive an adjusting nut 9 by which the tape is tightened upon the micrometer barrel or other work to be clamped.
In my invention, the work is clamped and unclamped by means at the free end of the handle. Consequently the work, as for eX- ample, an inside micrometer. can be inserted into a hole, the diameter of which it is desired to measure, and the grip on the barrel of the micrometer can be increased or decreased without removing the micrometer from the hole.
The device has no projecting parts to interfere with manipulating the micrometer when working in a narrow space.
In Fig. 1 the inside micrometer is shown with the handle attached. It will be noticed that in this case the handle grips the barrel of the micrometer about midway between its ends and consequently the instrument is practically balanced so that the handle tends to remain upright.
If, however, as Jfrequently occurs in the measuring of large diameters, an extension bar or rod is attachedto one end of the micrometer head, the instrument will no lonoer be balanced.
With my improved handle, however, the position of the handle can be readily shifted on the micrometer so as to support it in balanced position.
In this respect my invention is a distinct improvement over former handles that required to be attached, by screws or otherwise, to a certain place on the micrometer head. Where such handles are used. it is CG., OF
