CLOCK=PENDULUM.
SPECIFICATION forming part of Letters Patent No. 293,063, dated February 5, 1884.
Application filed August 1, 1583. (Model) 1"0 ctZZ whom, it may concern.-
Be it known that I, Lnvi Onsnn, of Mobile, in the county of Mobile and State of Alabama, have invented certain new and useful Improvements in Olock-Pendulums, of which the followingis a full, clear, and exact description.
Gloekpendulums are usually suspended by a thin strip of metal, known as the pendulumspring, and when hung in this manner are liable to wabble; and, besides that, the springs are liable to become bent, twisted, or broken.
The object of my invention is to suspend clock-pendulums in such a manner that the re sistance will be uniform in any position of the pendulum.
To that end the invention consists in a rolling or rocking suspension device constructed in such a manner as to give two curved lines or points of contact, upon or between which the pendulum is held byits own gravity when the clock is in its proper position, and in combination therewith a guard constructed so as to prevent the parts from becoming misplaced when the clock is turned out of its normal position.
In the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures, various modifications of my improved suspension device are shown, all con structed upon the same principle.
Figure 1 is a front view of a pendulum-rod suspended in correspondence with my invention. Fig. 2 is a sectional side view of the same. Fig. 3 is asectional side view, showing a modification in the construction. Figs. 4 to '12 represent further modifications, referred to hereinafter in detail.
In all the figures, a is the suspension stud or support, provided with a bearing, b, upon its upper side, upon which the loop or ring of the pendulum-rod d rests. c is the guard projecting above the ring 0. These partsviz., the stud a, the bearing 1), the loop 0, and guard eare the essential features of my invention.
The stud a may be either round, flat, square, diamond-shaped, or hook -shaped, as found most convenient and desirable. In Figs. 1 and 2 the bearing Z) consists of two half balls or hemispheres, between which the ring of the pendulum-rod rests.
In Fig. 3 the bearing 7) consists of a single segment-ring, and the pendulum-rod is formed with two rings, a, side by side, that rest upon the bearing 1), thereby giving the two points ot contact as before. In Figs. & and 5 the bearings b consist of two parallel segments 0t rings, placed at right angles to the stud a. W hen it is desirable to increase the bearing-surface, grooves may be cut into the bearings Z), so that the ring 0 shall fit the grooves smoothly, thereby giving a wider contact on each of the two bearingsurfaces. The bearings maybe of the rounded form shown, or they maybe made conical, the effect in either case being the same.
In Fig. 6 the stud a is formed with a groove having concave sides to receive the ring a, which rests upon the opposite rounded sides ot the groove. In Fig. 7 the ring 0 has a groove cut on its inner side to fit smoothly upon the single segment-ring, said groove being hollowed out in the center, so as to give two spaces of contact the reverse of Fig. 6. Fig. 8 has a plain oval bearing, Z), parallel to the stud a, being inclined downward from the sides to the center, which tends to keep the r ng 0 in its place. In this case the ring 0 is, ot necessity, so formed as to present two surfaces 01 contact'to the bearing 2). Either of the forms of ring 0 shown at Figs. 3 and 7 will answer this condition; or the ring 0 may be made square in section, as shown in Fig. 8. In Figs. 9 and 10 the ring 0 is made square in cross section, with a convex inner surface resting upon a segment of ring, also square in cross-section. In Figs. 11 and 12 is shown a compound application of the principle in which any ot the foregoing styles of bearings could be ou ployed its only novelty being the 1nterpos1- tion of an idle ring, on, between the bearings Z) and the ring 0.
The loop or ring 0 upon the pendulunrrod may be made by simply bending the upper end of the rod, and, instead of being a ring,thelower portions may be made of any desired shape, according to taste or requirements, either square, round, or triangular.
The form of the guard 0 may also be varied, the essential requirementbeing that it be held close enough to the ring to cause it to drop into the bearings whenever the clock is placed upright, yet far enough from the ring to pre vent any contact therewith when the latter is in place.
ICO
The stud a is formed with a shoulder, g, for holding the guard in place; but it may be held in-any suitable manner. YVith a stud made hook-shaped no guard would be required, provided the sides of the hook were so proportioned to the bearings as to prevent the ring from swinging forward over the hook. The lower end of the guard-plate is extended downward below the ring 0 and bent outward at right angles, the bent end forming a second guard, 71, that is made with a slot, through which the pendulum-rod passes, and in which it swings freely. This is in order to prevent the pendulum-rod from being swung so far out of position as to damage the verge or vergearm of the movement.
Both of the guards c It may be attached to the front frame of the clock, or elsewhere, independently of the stud, provided they are placed so as to fulfill the requirements as above mentioned.
A pendulum suspended in this manner will rock back and forth upon its bearing with the least possible amount of friction, and whatever resistance there is to its movement will always be uniform. In case the ring should rest upon the bearings to the right or left of the center, a few strokes of the pendulum would be sufficient to carry it back to the exact center, where it is held by its own gravity andany patcntable feature set forth herein and not hereinafter claimed, but reserve the right to claim the same either in a reissue of any patent that may be granted upon this application or in other applications for Letters Patent that I may make- Having thus'described my invention, I claim as new and desire to secure by Letters Patent- 1. A pendulum suspension formed to present two curved lines or surfaces of support or bearing parallel to each other and to the plane in which the pendulum swings, substantially as described.
2. The combination, with the ringer loop 0, of the pendulum-rod and the supporting-stud a and curved bearing 1), substantially as described, whereby the contact between the loop 0 and the bearing is taken upon two points or surfaces parallel to each other and to the plane of vibration.
The combination of the guard 6 with the LEVI ORSER.
