SPEED-INDICATOR.
SPECIFICATION forming part of Letters Patent No. 721,200, dated February 24, 1903.
Application lecl November 14, 1901. Serial No. 82,205. (No model.) y
To @ZZ whom it may concern,.-
Be it known that I, CLARENCEE. KELLY, a citizen of the United States, and a resident of Anderson, in the county of Madison and State of Indiana, have invented a new and Improved Speed-Indicator, of which the following is a full, clear, and exact description.'Y This invention relates to a' centrifugally in which similar characters of reference indi cate corresponding parts in all the views.
Figure 1 is an interior view of the casing. Fig. 2 is a similar view with the ring and radial inclines in place. Fig. 3 is an exterior view of the apparatus with parts broken away. Fig. 4 is a section through the line 4 4. of Fig. 2. Fig. 5 is a section of the casing-cover. Fig. 6 is an inverted fragmentary detail view of the ring and one of the radial inclines, and Fig. 7 is a sectional perspective of the complete device. l
The casing a, as best shown in Figs. 4 and 7, has a hub 0X, which is adapted to be fastened on a shaft or other rotary member the movement of which is to be measured. This casing a has within it a number of radial guideways 0.2, wherein are fitted spherical weights b. These weights are adapted to be actuated by centrifugal force, and they in turn act on radially-disposed inclined ribs c', fastened to a ring c. The ring c lies in the casing a concentrically to the hub ct', and its inclined ribs c are so disposed that they tit in the guideways a2, so that as the weights b move outward they ride along the inclined edges of the ribs c' and force the ring c to move longitudinally of the hub a-that is, along the axis of the casing ct and the shaft whereon the said casing is mounted.
One end of the casing a has a rabbetgroove a4 formed therein, and in this groove iits loosely a cover-plate d, (see Figs. 3 andv 7,) this plate lying around the hub a and having a groove d4 in its periphery, in which are received screws or other fastening devices ag, carried by the side walls of the casing a., By means of these screws the cover-plate d may be held vin place normally to turn with the casing and yet to be adjustable around Ythe hub ot when desired. The ring c is proare a number of pins cl2, bearing on the ring c.
These pins are preferably the same in number as the guideways a2 and theirapp'urtenances. The pins d2 are freely movable in the cover-v plate oZ and have their outer ends attached to an annulus cl3, which is adapted to have engagement with a means for operating the indicating device. These devices may, so far as the present case is concerned, be of any kindv desired or suggested Vto a skilled mechanic. Now it is clear that as the casing a turns the weights bwill bethrown outward, and this tends to move the inclined ribs c and ring c. The movement of the ring c imparts corresponding movement to the pins d2 and ring d3. Ifthe case is turning rapidly, the movement of the weights b will be greater than when the case is turning slowly, and the annulus d3 follows this movement, thus transmitting impulses to the indicating device, which impulses accurately correspond to the speed of the apparatus to which the invention is applied. By turning the cover-plate d relatively to the casing a a greater or less pressure may be applied by the inclined ribs d to the sp1-.in gs c2, and thus the movement of thering c may be retarded to'any extent desired. This enables the apparatus to be accurately adj usted according to the form and movement of the element to which it is-`applied.
