SPRING-SCALE.
SPECIFICATION forming part of Letters Patent No. 465,246, dated December 15, 1891.
Application tiled September 3,1891. Serial No. 404,581. (No model.)
To all whom t may concern.'
Be it known that I, CORNELIUS R. DAY, of the town of Blackstone, in the county of lVorcester and State ofl Massachusetts, have invented a new and useful Improvement in Spring Scales, of which the following is a speciication.
My invention relates to a new and useful improvement in the construction of springscales, the object being to provide a new and useful means of regulating and adjusting the scales; and it consists in so connecting the upper end of the spring to the lower end of the scale-bar that by means of a setscrew the position of the scale-bar in the shell may be altered and adj usted to compeusatefor the weakening of the spring and the wear of the parts by use, and also in connection therewith and as an aid in accomplishing the same object so connecting the lower end of the spring to a stirrup attached to the lower cap of the shell that by means of a connecting-bolt and an adjusting-nut the position of the scale-bar in the shell may be stillfurther altered and adjusted,and also in making the said connectingbolt a swivebbolt revolving in the stirrup so as to enable the scale-bar to revolve with the threaded cap in working the cap off and on to the shell, thus permitting the removal ot the working parts from the shell for repairs or adjustment.
The accompanying` drawings illustrate my invention, in which Figure 1 is a side elevation of my improved spring-scales when at rest. Fig. 2 is a longin tudinal sectional elevation of the same, show ing the scales in the operation of weighing. Fig. 3 is a perspective view of the lower part of the scale-bar, the set-screw, and upper end of the spring. Fig. 4 is aperspective view of the lug and swivel-bolt provided with its adjusting-nut.
Like letters of reference indicate corresponding parts throughout the several views.
A is a cylindrical metallic shell having its two ends threaded and provided with ,screwn threaded caps l5 and b, adapted to work onto the ends of the shell, respectively.
C is a flattened scale-bar graduated to indicate degrees of weight, but may be of any suitable and desirable form and length. lt
is provided at its upper end with a ring D, adapted for hanging the scales upon its proper support. The scale-bar is inclosed within the shell A, its upper end extending through a slot or opening E in the cap B,and is provided near its lower end with a longitudinal slot F, extending transversely through the bar. The lower termination of the scalebar is enlarged in a cylindrical form, through which a hole is drilled longitudinally upward into the lower end of slot F, which hole is threaded and adapted to receive a set-screw to work therein.
G is a set-screw adapted to work upward through the said hole in the lower end of the scale-bar into the slot F.
H is a close-coiled spring inclosed within the shell A, having its upper end hooked to the scale-bar through the slot F, the hooked end resting in said slot upon the end of setscrew G. By use the spring will lose something of its elasticity, and the various parts will wear at the several points of connection, which will render the scales inaccurate in weighing. Then this occurs, a proper readj ustinent is readily secured by simply turning the setscrew G, whereby the position of the scalebar in the shell may be altered and properly readj usted, thus compensating for any loss of elasticity or weakening ot the spring that may ensue and the wear of the parts.
I is a swivel -bolt having its lower end threaded, and through a hole in the head of which the lower end of the spring is hooked.
K is a metallic stirrup, the lower end of which is made to pass down through a slot in the cap l1 and held firmly in position by a removable pin o3, tightly driven through a hole in the lower end of the stirrup at the lower surface of cap Z). To the lower end of stirrup K the ordinary hook L is attached in the usual way for the supportl of the article to be weighed. Stirrup K is so constructed as to form near its upper end an open chamber or loop by means of its inclosing sides. Through the upper end of the stirrup a hole is drilled into this chamber for the reception of the swivel-bolt l, the lower end of which bolt is threaded. The bolt turns easily in the stirrup, thus enabling the spring and scale-bar to revolve with cap B in working the cap off IOO and on to the shell, for the purpose of removing the Working parts for repairs or adjustment. This swiveling feature of the bolt I becomes useful only when the flattened form of scale-bar is used, or such other form as must necessarily revolve with cap B. When the cylindrical forni or such other form of the scale-bar is used that the cap B can be unscrewed Without revolving` the scale-bar, the bolt I need not be made so as to revolve in the stirrup. I regard the flattened form as best, because it aiords the largest surface for the graduated scale.
M is an adjusting-nut adapted to Work upon the end of bolt I. By simply turning adjusting-nut M the position of the scale-bar in the shell may be still further altered and adj usted to more fully compensate for any loss of elasticity or weakening of the spring or wear of the parts. A
The two modes of regulating the scales above described may be used together in aid of each other or singly, as the exigency of the ease may require. To adjust or regulate the scales it is only necessary to remove pin a: and unscrew cap B, when the scale-bar,
spring, and stirrup, connected together as described, can be readily removed from the shell and the proper adjustment made, as described.
lVhat I claim as my invention isl. The combination oi shell A, cap B, having therein slot E, graduated scale-bar C, having therein slot F and provided With ring D, set-screw G, spring I-I, bolt I, adjusting-nut 35 M, and stirrup K, substantially as described.
2. The combination of scale-bar C, having therein slot F, set-screw G, and spring Il, substantially as described.
3. The combination of the scale-bar C, hav- 4o ing therein slot F, set-screw G, spring II, bolt I, adjusting-nut M, and stirrnp K, substan- `tially as described.
4. The combination of shell A, cap B, having therein slot E, graduated scale-bar C, 45 spring Il, swivel-bolt I, adjusting-nut M, and stirrup K, substantially as described.
