ADJUSTING DEVICE FOR TOOLS, &O.
SPECIFICATION forming part of Letters Patent No. 269,754, dated December 26, 1882.
Application liled November 272, 1881. (No model.)
To all whom it may concern:
Be it known that 1, JOHN F. WEBs'rER, a citizen of the Dominion of Canada, residingat Springfield, in the county of Clarke and State of Ohio, have invented certain new and useful Improvements in Adjusting Devices for Mechanics Tools, Mathematical and other Instruments; and I do hereby declare the following to be a lull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
Myinvention relates to an improved adjusting device for calipers, compasses, and similar instruments.
The invention consists of parts and combination of parts, all as will hereinafter be described and claimed.
Referring to the drawings, Figure 1 represents a pair of machinists calipers. Figs. 2, 3, and 4 are views of inside calipers, the latter view showingthe three principal members (inclusive of the adjusting lever) in longitudinal section; and Fig. 5 a side elevation of a pair of compasses.
A represents the devices, each having legs 0f and f, secondary part or lever a, pivotal nuts (I d, the screw 1)", and the bolt 11'. The secondary part or lever to is preferably provided with a conical journal, 0, which fits snuglyin a correspondingly-shaped bearing, 0, in the leg or primary partf. The secondary and primary parts are held together by means ot'a bolt, bf, which is provided with a screw-threaded end, that is inserted in similar threads in the secondary part or lever c, said lever serving as a nut to clamp the parts together. Upon the lever a, at any suitable point, is a pivotal nut, d, which corresponds to a similar nut, 61, attached to arm f of legf. These nuts may be placed upon the same side of lever to and arm f, or they may be placed on opposite sides-that is to say, on sides which face each other. An adjusting-screw, I), is inserted in the nuts and draws lever 64/ and arm f together or forces them apart, as desired.
In Fig. is shown a pair of inside calipers, having my improved device for adjusting the primary parts. In this tool, and in the others of this class represented in Figs. 1, 2, 4, and 5, the cone-journal is formed upon the axial end of the lever. It is shown in Figs. 1,2, and 3 in dotted lines, and more plainly in the sectional view, Fig. at. This cone may be either formed solid ot' the same piece with the lever, or it may be made separately and riveted on or otherwise fastened to it. One leg of the calipers or compasses has the conical bearing 0 bored through it, as seen in the legf, Fig. 4. In inside calipers and compasses this limb is cut oil above the joint, as the adjusting-lever a stands vertically, for convenience in bringing its pivoted nut d on a line with the not (1 on the end of partfior the adjusting-screw M, v hich extends through them. In the outside calipers the nut d is pivoted on one leg of the tool a little below the joint on the outside edge. This arrangement may also be modified by having the fixed lever or arm 1' extending from legfin any required direction for the not (1. In this form of adjustment the axial head of lever a" being let into one of the legs of the calipers or compasses, its hole is threaded for the screw 11,so that it forms one part of thejoint, which is not only made stronger, but is much better adapted for ease in working and for adjustment than the ordinary joint. By placing lever a upon the outside it serves, as before stated, as a not for the screw on the pintle or pivot of the primary parts.
I am aware that a secondary leg mounted upon the same pintle as the primary parts, and adjusted by means of a screw-bolt working in a screw-threaded hole in one of the primary parts, and having a swiveled nut upon one end, which, when the parts are adjusted by means of the screw, slides in a groove upon the secondary part, is old. I am also aware that dividers have been provided with pivotal bearings in the legs below thejoint, and having a screw provided with right-hand threads at one end for adjusting one leg and a lefthand screw on the other end for adjusting the remaining leg; but this device dilfers from mine, in that the legs cannot be adjusted independently ot' the screw.
What I claim as new is- 1. ln calipers, dividers, or .like devices, the combination, with the primary parts, of a secondary part having a screw-threaded opening and placed upon the outer side of the primary parts to serve as anut for the pintle of ti: device, and an adjusting-screw attached to the secondary and one of the primary parts, for the purpose set forth.
2. In acalipers or like device, the combination, with the primary parts, of a secondary part having a screw-threaded opening and placed upon the outer side of the primary parts to serve as a nut for the screw-threaded pintle of the device, and an adjusting-screw having pivotal hearings attached to the sec-,
ondary and one of the primary parts, for the purpose set forth.
3. In a calipers,compasses, or like device, the combination, with the primary parts, of a secondary part having a screw-threaded opening and placed upon the outer side of the primary parts to serve as a nut for the screw-threaded pintle of the device, and an adjusting-screw having pivotal bearings attached to the inner side of the secondary and one of the primary parts, for the purpose set forth.
