JOHN E. KAMPE, or WALTHAM, MASSACHUSETTS.
INDICATOR ATTACHMENT FOR CALIPERS.
Specification of Letters Patent.
Patented April 2, 1907.
Application filed June 18,1906. Serial No. 322,264.
To all whom it may concern:
Be it known that I, JOHN E. KAMPE, a native of Sweden, residing at Waltham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Indicator Attachments for Calipers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it app ertains to make and use the same.
This invention relates to improvements in indicating devices for calipers.
The object of the invention is to provide an attachment of this character by means of which the balance-wheels of watches may be quickly and accurately tested.
A further object is to provide means whereby the indicator is adjustably and pivotally connected to the caliper.
With the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter de scribed and claimed.
In the accompanying drawings, Figure 1 is a side View of a pair of calipers, showing the application of the invention thereto. Fig. 2 is a sectional view of the same on the line 2 2 of Fig. 1. Fig. 3 is an enlarged detail longitudinal sectional view of the indicator and its supporting mechanism removed from the caliper. Fig. 4 is a cross-sectional view of the same on a line with the clamping-screw therein. Fig. 5 is a detail perspective view of the adjustable post and the indicating-bar carried thereby, and Fig. 6 is an edge view of the inner edge of the indicating-bar.
Referring more particularly to the drawings, 1 denotes the calipers, which are here shown as of double form. In the ends of the jaws are arranged bearing studs or points 2, in the outer ends of which are formed bearingrecesses, with which are adapted to be engaged the ends of the shaft of the balancewheel of a watch, whereby said wheel is revolubly supported in the calipers. Pivotally connected to one member of the jaws of the caliper is a sleeve or socket 3, said socket being slit or bifurcated at its outer'end, as shown at 4, and said outer end being slightly reduced, as shown at 5. Arranged on the reduced outer end of the socket is a clamping band or collar 6, in which is arranged a clamping-screw '7, which when screwed inwardly is adapted to clamp the split end of the sleeve or socket into tight engagement with a post 8, on the outer end of which is mounted a bifurcated head 9.
Pivotally mounted in the bifurcated head 9 of the post 8 by means of a pivot-screw 10 IS an indicating bar 12, said bar having obliquely-disposed ends which are beveled in the same'direction from one side of the bar to the other, as shown at 13. In the inner edge of the bar 12 adjacent to its opposite ends are formed curved recesses or notches 14, the walls of which are beveled or inclined in the same direction as the ends of the bar, as clearly shown in Fig. 6 of the drawings.
By providing an adjustable connection for the post 8, as herein shown and described,
said post and the indicating-bar 12 may be adjusted to any desired position and turned at any desired angle, and by pivotally mounting the bar 10in the outer end of the post said bar may be turned or inclined at any desired angle in a plane opposite to that attained by turning the post 8 in the sleeve or socket 3. The pivotal connection of the socket 3 with the caliper 1 will permit the socket 3 to be swung toward or from the proximate points 2, thereby providing for the moving of the bar 12 to the desired angle, thus enabling the device to be used for testingbalance-wheels of any size or construction.
From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.
Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined by the appended claims.
Having thus described my invention, what I claim as new, and desire to secure by Let- 3. An indicating attachment for calipers comprising a socket pivotally mounted on a a jaw of said caliper, said socket having a split or bifurcated outer end, a post slidably mounted in said socket, a clamping band or collar arranged on the bifurcated outer end of the latter, a clamping-screw arranged in said band or collar to clamp the bifurcated outer end of said socket into engagement With said post, and a double-ended indicating-bar pivotally mounted on the outer end of said post, substantially as described.
4. An indicating attachment for calipers comprising a socket pivotally mounted on a jaw of said caliper, said socket having a split or bifurcated outer end, a post slidably mounted in said socket, a clamping band or collar arranged on the bifurcated outer end of the latter, a clamping-screw arranged in said band or collar to clamp the bifurcated outer end of said socket into engagement With said post, an indicating-bar pivotally mounted in the outer end of said post, said bar having obliquely-disposed beveled ends, and curved beveled recesses formed in one edge thereof, substantially as described.
5. An indicating attachment for calipers comprising a socket pivotally mounted upon one member of the caliper-jaws, said socket having a split or bifurcated outer end, a post slidably mounted in said socket, means to clamp the bifurcated outer end of said socket on said post, a bifurcated head formed on the outer end of the latter, apivot-screw arranged JOHN E. KAMPE.
