JOSEPH A. BEECE, OF SPRINGFIELD, MASSACHUSETTS.
BEAM-CALIPERS.
SPECIFICATION forming part of Letters latent No. 264,339, dated September 12, 1882.
Application filed May 2, 1882. (Model.)
To all 'whom it may concern Be it known that I, JosEPHA. REECE, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Beam-Calipers, of which the following is a specification.
This invention consists of improvements in beam-calipers, and relates, 4as hereinafter fully set forth, to the construction of the movable jaw thereof and mechanism for operating the same.
In the drawings, Figure I is a side elevation, in partial section,ofmyimproved caliper. Fig. II is a top view. Fig. III is a partial detail view. Fig. IV is a partial sectional elevation on the line y y of Fig. I, and Fig. V is a partial sectional elevation on the line o n of Fig. I.
B is the beam, having on one end the fixed jaw C. The beam from the xed jaw C throughout its length is formed as shown in the end views, Figs. IV and V, with a bore, b, connecting with its surface through the op'ening c, of smaller diameter. The beam B is of the usual form of constructionin having its outside bearing-surfaces, upon which one jaw moves, parallel to its bore, and in having the fixed jaw C at right angles thereto. Through the fixed jaw G the bore b is prolonged to the outside, though ot' reduced size, to receive one end of rod D. The rod D, passing loosely through the base of the xed jaw, is from thence prolonged axially through the bore b of the beam, as shown in Figs. I and II. One end of rod D is threaded, as at d, and in passing through the fixed jaw is received through the nut F, recessed in said jaw.
The movable jaw H, formed as shown in Figs. I and Ill, has a base or shank, g," connected by a neck, g', to a iiange or bearingsurface, f. The base g and neck g conform loosely in cross-section to the bore b and opening c therefrom, and the surfacefconforms to the top surface, m, of the beam B. Both surfaces g andf of jaw H have an extended longitudinal bearing upon the beam, to maintain the measuring-surface of the jaw always at right angles to the beam. The base gis bored leigltiwise to receive loosely through it the ro The jaw H is provided with a screw, G, ar-
ranged to extend vertically from its top to have one end intersect the bore through which passesrod D,asshowniudetail,Fig.V. When the jawH is connected with the beam, as shown in Figs. I and II, and the end ofthe screw G removed from contact with rod D, the jaw H may be quickly moved to anypoint for a rough adjustment. When the screw G is moved to clamp jawH and rod D together the revolution of nut F slowly slides jaw H upon the beam to obtain the finest adj ust-ment, the exactness of measurement which the instrument is capable of making and indicating being only limited by the neness of the scale with which it may be provided.
Combined withjaw H and bea-m B is a plate, I, which conforms to and rests upon surface m of the beam,aud extends transverselythrough jaw H in the opening t'. The vertical walls of the opening t' correspond with the sides of the plate I, and the opening i is deep enough in vertical section to permit the jaw H a vertical movement relative lto plate I. From the top of jaw H a set-screw, J, communicates, through opening t', with the top ot' plate I. The plate I is provided with side anges, as shown, to retain it to the face of the beam B. Then the required adjustment has been obtained to the jaws, and it is desired to retain them in that position, the screw J is run upon the plate I to eifectually clamp the jaw H and beam together.
The slight inferiority of size of base g ofjaw H to the bore of the beam permits thejaw to slide freely in the beam and take the plate I with it when released by screw J; but when the screw J is moved against plate I the jaw H, guided vertically by the sides of plate I, has its base g brought to bear against the upper surface of the bore b. l
In the drawings (made to a scale ot' twice the natural size) the caliper is represented with jawH clamped to both the beam B and rod D. The slight play required by rod D to follow the vertical movement of jaw H in the beam is furnished at its nut end without interfering with the efficiency of the co-operatin g screw, nut, and nut-bearing.
N ow, having described my invention, what I claim is- 1. In a beam-caliper, the combination and IOO arrangement of the rod D, having the threaded end d and nut F, recessed in the fixed jaw G, 'with the movable jaw H, having the clampscrew G, substantially as shown and described. 5 2. In a beam-caliper, the combination, with a hollow beam, B, having a bearing-surface beneath its top face, of the movable jaw H, having the base g inelosed within the beam, the set-screw J, and the intermediate bearing-sur- Io face, I, all arranged to operate as and for the purpose shown and described.
3. In a beam-caliper, the combination and arrangement of the rod D, having threaded end d and recessed nut F, With the hollow beam B, and with the movablejaw H, havingon it meeh- 15 anism, substantially as shown and described, for successively clamping the rod D and beam B, as and for the purpose set forth.
