UNITED STATES PATENT OFFICE.
VINCENT D. ZITO, OF HARTFORD, CONNECTICUT.
GAGE.
To all whom it may concern:
Be it known that I, VINCENT D. Zrro, a citizen of the United States, residing at Hartford, in the county-of Hartford and State of Connecticut, have invented certain new and useful Improvements in Gages, of which the following is a specification;
This invention relates to gages, the object of the invention beingthe'provision of an article of this character which is simple in construction and-efficient in action and by which I can in a ready and simple manner, check up the accuracy of parts of various kinds and especially those of tubular construction. V
The article comprises other features of novelty and advantage which with the foregoing will be statedat length in the following description wherein I will set forth in detail that one of the several forms of embodiment of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. I am not limited to this disclosure;
- I may depart therefrom in several respects within the scope of the invention defined by the claims following said description.
Referring to said drawings:
Figure l is a side elevation of a gage involving the invention and showing a way of using the same in connection with work.
Fig. 2 is a top plan view of said gage.
Fig. 3 is a face view of a portion of the indicating means.
Fig. 4 is a sectional detail showing a piece of the work and a portion of the instrument in engaging .relation therewith.
Like characters refer to like parts throughout the several views which are on different scales.
The instrument may be employed with advantage in many dlfi'erent ways. In the construction, for instance, of certain kinds sential, for accuracy, that the interior of the work should be precisely determined. This so far as I am aware has heretofore been done by feel or really guess. I have provided an instrument by which the accuracy of a tubular part interiorly may be determined with positiveness and preciseness, leaving therefore nothing to the imagination, and not only can I secure this result in the way noted, but I can do so in a ready Specification of Letters Patent.
Application filed May 14, 1919. Serial m. 297,043.

and quick manner, as I will more particularly explain herelnafter.
The device desirably includes in its makeup, two legs as 2 and 3. These might be considered the primary legs, not because they are in any sense more important than what may be considered as a secondary leg as 4, but merely to better distinguish them. I will hereinafter describe a way in which the secondary leg 4 may be mounted. The primary legs are shown as having near their outer ends apertures of semi-circular form or virtually so, which mate to receive the pivot 5 headed atitsopposite ends to hold it in place. legs 2 and 3 can swing relatively or together about the stud or pivot .5. The legs on their outer branches near their center mount are notched to receive'the free ends of the bowed spring 6, which constantly tends to spread the long branches of the legs, this action however, being resisted in some suitable way, a form of which will now be described.
The legs 2 and 3 are provided with laterally extended pins 7 and 8, with one of which as the pm 7, a screw as 9 is rigid. This screw extends freely through a transverse hole in the pin 8 and its outer threaded portion receives an adjusting nut 10. If the thread of the screw 9 and the nut 10 be a right one, the nut 10 will be turned to the left to back it off or move it upward in Fig. 1, and on this motion, the spring 6 operating against the primary legs 2 and 3 tends to separate the forward or long branches of the legs. By oppositely rotating the nut, it will act against the pin 8 and will move the long branches of the legs 2 and 3 relatively toward each other.
The primary leg 2, as will hereinafter appear, during a gaging operation, engages the work, while the primary leg 3 does not, of tubular work, it is desirable if not esthe secondary leg 4 however, during such action engaging the work. The secondary leg is provided between its ends with an -It will be clear that the v outstanding ear 11, which receives a pivot 12 for instance in the form of a screw, threaded into an ear 13 extending outwardly from the clip 14, straddling and secured to the primary leg 3 adjacent the free end of the long branch thereof. The pivot 12 by which the secondary leg 4 is mounted, is so disposed that the said secondary-leg has a short forward branch and a long inner branch. The forward branch of said leg 4 has a lateral extension 15 which overhangs the free end of the long branch of the primary leg 3, the outer surface of this lateral extension 15- being adapted to directly engage the interior of tubular work as 16 dur: ing the functioning of the implement, and
. coeperating at such time with the free outer ment, gaging-means of suitable character,
end of the long branch of the primary leg 2, as shown best in Fig. 1. 7
There is in connectlon with the instruother suitable way, to the outwardly diverging flanges 22 of the body portion 18. The lower part of the back of the body portion 18 is furnished with a scale as 23 of prac-- tically arcuate form, the graduations reading oppositely from the central character,
which is assumed to be zero.
The rear end of the secondary leg 4 extends through the slot or opening 22' in the left wall 22 (Fig. 3) and is" reduced as at 24, to fit a perforation in the slide 25, which when in action, traverses the inner Y face of said left wall. Pivotally mounted upon the front or inner face of the back of the body portion 18, near the upper reduced end thereof, is a pointer, finger or needle 26, having below and comparatively close to its center of motion the pin 27 against which the longer arm of the angle or elbow lever 28 constantly abuts. This angle lever is shown as pivoted at its elbow to the back of the body portion 18 near the lower left side thereof and its short arm is in constant engagement with the lower end of the slide or motion transferring member 25. Within the carrier 17 is a spring as 29 shown as being of coiled form, and connected at'its upper or outer end with the slide 25 and at its lower end to a pin as 30 near the lower end of the back of the body portion 18. Surrounding the pivot of the pointer or finger 26 is the coiled portion of a spring 31, the short branch of which acts against the pin 27 and the longer branch of which acts against the right wall 22.
There are a number of ways of course in which the instrument can be used.- It is customarily employed in connection with a micrometer. It will be supposed that a piece of tubular work has been finished at their free ends willengage the microm-' eter in such mannerthat the secondary leg, through the connection described, will move the needle or pointer 26 until the free end thereof comes opposite the zero mark of the scale 23. When this is done, the instrument, the subject of the present case, is I introduced into the work 16, until the free eridsof the legs 2 and 4 engage the wall of the work at diametrically opposite points.
If the work be of the exact size, the pointer.
26 will be caused to come opposite the zero mark of the scale 23. If the work be under size, the free. branch of the le 4: will be swung in, thereby moving the s ide- 25 u wardly or outwardly, the lower end of t e slide as a consequence tending to move away from the short branch of the angle lever 28, and the spring 29 as a consequence being stretched. As a result of this,'the long arm of the angle lever 28 tends to move away from the pin 27 so that the branch of the spring 31, which isagainst the pin 27, can swing the pointer 26 to the right in Fig. 3 an amount equal to the under. size, the graduations of the scale 23 being formed to represent thousandths of an inch. Should the work be over size, the spring 29 acting against the slide 25 tends to pull the same downwardly or inwardly, the over size permitting this action. On such downward movement of the slide, the latter acting against the short branch of'the angle lever 28, swings the longer or upper branch outwardly or to the left so that the said longer branch engaging against the pin 29 can in effect directly swing over the pointer or finger 26 to the right} What I claim. is: v
