ADJUSTABLE GAGE.
SPECIFICATION forming part of Letters Patent No. 288,375, dated November 13, 1883. e
Application filed March 31, 15583. (No model.) I
f0 aZZ where it may concern.-
Be it known that I, SANFORD E. STACY, of Springfield, in the county of Hampden and State of Massachusetts, have invented anew and useful Improvement in Adjustable Gages, of which the followingis a specification and description. j
The object of my invention is to provide an adjustablegage adapted to measure or caliper any article, and having one jaw fixed solid to the screw and guide bar .and the movable jaw adjusted to any desired point along the screwbar and graduated guide-bar; and I accomplish this by the mechanism substantially as hereinafter described, and illustrated in the accompanying drawings, in'which Figure I is a side view of my invention. Fig. II is an end view of the same, and Fig. III is a vertical longitudinal section at the axis of the screw-bar. a l.
In the drawings, 2represents a main bar, of cylindrical form, and having a screw-thread made substantially its entire length, To one end of this bar is firmly secured a jaw, 7, which is fixed in its position on theend of this screw-bar 2, and amovable jaw, 3, whose head is elongated and is provided with an opening, 4, has a hole made longitudinally. through this elongated head, in which the screw-bar 2 is fitted, so that the jaw may be moved freely to and fro along this bar.
A nut, 5, has a screw-thread made through it, which is fittedto turn in the thread along the screw-bar and this nut5 is of such thickness as to fit snugly in o the opening 4: in the direction of thelength. of the screw-bar, but so as to revolve freely in said opening, with out lost motion, when turning on-the bar. Another similar nut, 6, isadapted to be turned upon the screw-bar, and is located between the head of the jaw 3 and the block 8, so that it may be turned up against the rear end of the head of the movable jaw 3, as shown clear ly in Figs. I and III.
A guide-bar, 9, extends through a hole in the movable jaw, and is firmly secured atone end in the fixed jaw7, and at the other end in the block 8, the. latter being also fixed to the end of the screw-bar 2,
" Before the block Sis secured in place to the end of the bar 2 the nut 5 is placed in the opening 4 in the head of the jaw 3, and the bar 2 is inserted through the hole in the front partof the head of the jaw 3 and into the nut 5, and the latter is then turnedonto and along the bar 2 until the latter extends entirely through the head of the jaw 3, and the nut 6 is then turn ed-on and both nutsturned along the bar until the end of the screw-bar extends entirely through the nut 6. The block 8 is then secured firmly to the ends of the screwbar 2 and guide-bar 9, the latter being parallel with the screw-bar 2.
To render the instrument accurate for making minute measurements, I divide the circumference of the nut 5 into anydesired number of equal parts and mark themsay, eight equal parts-and I make an index-mark on the head of the jaw 3, opposite the marked edge of the nut 5. I prefer to also mark the guide-bar 9 atequal distances along its length, as shown in Figs. I and III, so that a single revolution of the nut 5 on the screw-bar 2will move the jaw 3 from onemark to the next along the guide-bar 9, so that if one of the subdivisions on the bar 9 equals one-twentieth of an inch and the circumference of the nut 5 is divided into eight equalparts the revolution of said nut 5 from one mark to the next on its circumference'will move the jaw 3 along the bars 2 and 9 one-eighth of onetwentieth of one inch, or the hundred and sixtieth part of an inch. Of course any other subdivisions'of the bar 9 and of the circumference of the nut may be made as desired and as may be'most convenient for use.
To measure any article, the latter is placed between the jaws 7 and 3, and the nut 5 turned on the bar 2 until the jaw 3 comes into contact with the article on one side, while the inside of the jaw 7 is in contact withthe other side, and when this is done nicely, but so the two jaws canbe removed from the article, the nut 6 is turned up against the rear end of the head of the jaw 3, and, the latter is thereby firmly held in that position on the bars 2 and 9.
This instrument is adapted to a great variety of uses, and is particularly adapted for use in tool'makers work, and is much less complicated in its construction than the ordinary Vernier gage. If it is desired to use the gage for temporary measurements, the checknut 6 may be turned backon the screw-bar 2 towards the block 8, and the gage used with the operating-nut 5; but if it is desired to keep the measurements which may be taken for any length of time, the check-nut 6 may be used, as by turning the latter up against the rear end of the head of the jaw 3 the latter cannot possibly be moved out of place, even by any attempt to turn the operating-nut 5.
Having thus described my invention, what I claim as new is 1. An adjustable gage consisting of the combination of the screw-bar 2, the guide-bar 9, the jaw 7, fixed solid to said guide-bar and screw-bar at one end, and both said bars secured in a parallel position by a block, 8, fixed to the other end, the jaw 3, movable on the bar 2, and an operating-nut, 5, graduated on its periphery to turn on said screw-bar and in the opening 4 in said movable jaw, all substantially as described. a
2. The combination of the screw-bar 2, the 20 guide-bar 9, the jaw 7, fixed solid to said guidebar and screw-bar atone end, and both said bars secured in a parallel position by a block, 8, fixed to the other end, the jaw 3, movable on the bar 2, an operating-nut, 5, graduated 25 on its periphery to turn on said screw-bar and in the opening 4: in said movable jaw, and a check-nut, 6, adapted to be turned on said screw-bar 2 against the movable jaw 3,
substantially as and for the purpose described. 0'
