The present invention relates to gauges, and has particular reference to gauges ofthe type having a pair of gauging elements by means of which it may be determined whether the articles to be gauged are within predetermined limits of variations or tolerances. The
i features of the present invention find peculiar adaptabilityin .devicesfor gauging screw threaded members, although they are not limited thereto. i u
The aim of the invention is to provide a gauge of this type having various features of novelty and advantage and which is particularly characterized by its simplicity in construction, its economy in manufacture, the
ease and security with which the gauging members may be anchored in place in the frame or body portion, and the facillty with which the parts may be disassembled.
Other objects will be in partobvious, and
in part pointed out more in detail hereinafter. The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the appended claims. H
In the accompanying drawing, wherein is shown, for illustrative purposes, one of the embodiments which the present invention may take:
Fig. 1 is a face view of the gauge;
Fig. 2 is a sectional view taken on line 2-2 of Fig. 1; and
Fig. 3 is a perspective view of the frame or holder.
Referring to the drawing in detail, designates a frame or holder, preferably formed of aluminum or other light material. The frame comprises a flat block of generally elongated shape. One end of the holder may be curved, as at 11, and the other end may have flat faces 12 so that the operator, by the mere sense of touch, may quickly and readily determine which is the g0 end of the gauge and which is the no-go end. The frame has, located to each side of itscentral portion, an opening 9, preferably of circular form and adapted to respectively receive correspondingly shaped gauging members, which may be in the form of circular disks 13. The. portion of the frameor body between theopenings extends from one side of the frame and terminates short of the other side and is transversely split, along a medial line, as at 14, soas to provide a pair of arms 15. At the bottom of the split 14 is an enlarged opening 16 so as to increase the springiness of the arms 15. In the opposed faces of the arms are complementary semi circular grooves 17 which, together, form a hole slightly tapered in the direction of its length. Inthe side or marginal portion of the frame, opposite the free ends of the arms 15, is a hole 18 in registry with the hole formed by the grooves 17-. or the purpose of spreading the arms apart, and thereby clamping the gauge members in place, there is provided a wedge 19 which is inythe form of a tapered pin circular cross section. This pin is adapted to. be inserted through the hole 18 and be engaged in the grooves 17 The gauging elements maybe of any suitable kind, but they are here shown as com- ;prlslng'the disks 13 having central threaded openings from which extend slots 26.
Eachof these disks may be split at one side,
as at 27 Thus, these gauging members may be slightly contracted. It is, of course,understood that the openings 25 of the gauging members will be of acharacter depending upon the characteristics of the objects to be gauged and the limits of tolerance. In the event that threaded members are. to be gauged, these openings are provided with threads complemental to the threads desired on the members to be gauged, and one of the openings will beslightly larger than the other so as, in effect, to provide a go and no-go gauge. Gauging members of this type are old and well-known.
From theforegoing description, taken in connection with the accompanying drawing,
it will be observed that my improved structure is a very simple one, and may be very cheaply manufactured. The gauge merely comprises the integral, one-piece frame or body portion and the tapered pin. To assemblethe parts, it is merelynecessary to position the gauging members in the openings 9 in the frame; insert the pin into the hole 18 and between the arms 15, and then force the pin in until the arms have been forced apart to such an extent as to securely clamp the gauging members in place. Due to the slight taper in the pin and the resiliency of the arms, accidental derangement of the pin, after it has been adjusted, is eliminated. To disassemble the parts, it is merely necessary to force the pin from position, which may be done by inserting a suitable tool in the opening 16 and bringing it against the inner end of the pin. y
As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all mat ter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of-the scope of the invention which, as a matter of language, might be said to fall therebetween.

In a gauge, a closed frame having a pair of circular openings adapted to respectively receive two gauging members, said frame having between said openings and forming port-ions of the walls of said openings a transversely extending central portion slit in a direction transversely of said frame and free atone end, and a tapered pin adapted to be inserted between the parts of said central portion,
5. In a gauge, a closed frame having a pair of circular openings positioned side by side, said frame'having between said openings a pair of arms positioned side by side and respectively forming portions of the walls of said openings, said arms being capable of moving towards and away from one another, the opposed faces of said arms having complementary grooves, and a tapered pin adapted to be inserted in said grooves.
63. In a gauge, a closed frame having a pair of openings and a central portion between said openings, said central portion extending from one inside wall of the frame and terminating short of the other inside wall and being transversely slit to provide a pair of arms capable of moving towards and away from one another, the opposed faces of said arms having complemental grooves forming a slightly tapered hole, said frame having an opening in the wall thereof opposed to the free ends of said arms, and a pin adapted to extend through said opening and into said hole.
7. In a gauge, a frame comprising a flat elongated block having a pair of openings, said frame having between said openings a pair of arms positioned side by side and extending from one inside wall of the frame and terminating short ofthe opposite inside -wall, said arms being capable of moving towards and from one'another the opposed faces of saidarms having complemental grooves forming a tapered hole, there being an opening atthe bottom of said hole, said opposite side wall having an aperture registering with the hole formed by said grooves, and a tapered pin adapted to extend through said aperture and into said grooves.
