PENDULUM-CLAMP FOR CLOCKS.

SPECIFICAT ON forming part of Letters Patent No. 576,587, dated February 9, 1897.

Application filed August 22, 1896. Serial No. 603,577. (No model) To ail whom it may concern:

Be it known that I, FLORENCE KROEBER, a resident of the city, county, and State of New York, have invented certain new and useful Improvements in PendulumSupporters, of which the following is a specification.

My invention relates to pend ulum-supporters, and has for its object to produce a device which will lift and support the pendulum, taking the weight of the same off the pendulum-rod and tension-spring, so that the clock may be transported with the pendulum in place.

To this end my invention consists in the construction hereinafter set forth and claimed.

In the drawings, Figure 1 is a front or face view of a pendulum-support made in accordance with my invention. Fig. 2 is a sectional plan view of Fig. 1, the section being taken on line 2 2 of Fig. l; and Fig. 3 is a similar view of the same, showing its closed position. Fig. 4 is a front or face view of a pendulumsupport constituting another form of my invention. Fig. 5 is a sectional plan view thereof, the section being taken on line 5 5 of Fig. 4; and Fig. 6 is a front face view or elevation similar to Fig. 4, showing the pen' dulum-supporter in its elevated position.

In the drawings, Figs. 1 to 3, A indicates a clock-movement from which a pendulum B is suspended by the ordinary suspension or pendulum rod 0, and the suspension-spring D, which works freely up and down in the suspension-post E. It is well known that the suspension-spring D is very delicate, and a jar imparted to the pendulum-ball is liable to cause the spring D to be torn by the pin which passes therethrough and rests on the top of the slot of the suspension-post E. Especially is this liable to happen when the clock is shipped with the pendulum in place. By my invention I obviate this danger by raising the pendulum-ball to take the weight off the suspension-spring and at the same time securely clamping the pendulum-ball to prevent it from moving after it has been lifted, so that the pendulum will be securely held from all movement. This device Ihave illustrated in the drawings, wherein F is a post carrying a yoke G, whose top cross-bar II is slotted for the passage of the pendulumrod 0 and for the passage of the upper edge of the pendulum-ball B when the same has been lifted. Pivoted to the top of the yoke are toggle-levers a Z), to which a pair of toggle links or levers c dare pivoted by one end and pivoted together at c. Pivoted to the ends of the links or lovers to d is a link or lever f, the said three levers being pivoted together at a common point g. Pivoted to the common junction or pivotal point 7L of the levers b o is a lever Vol-king on the side bars j l; of the yoke G is a sliding cross-bar I, to which bar the links f are pivoted by their lower ends. The spring J is interposed between the bar I and the standard F. The operation of this form of my invention is as follows:

Supposing the parts to be in the position shown in Fig. 1 and it is desired to lift and clamp the pendulum, the toggle-links 0 (Z are forced downward, thereby forcing their lower ends apart and bearing upon the toggle-links b i and a f, so as to raise the bar I to cause the same to lift the pendulum-ball, so that the pendulum-ball will be firmly gripped between the bars II I, thereby being secured from movement and being supported by the bar I, so that none of the weight of the ball comes on the pendulum-rod or the suspensionspring D.

In Figs. 4, 5, and 6 I have illustrated a modification of my invention. In these figures, F indicates the base or standard of the yoke G, as in the former case, and II the top cross-bar thereof, which top cross-bar is slotted, as before, for the reception of the pendulum-ball when it is raised. Pivoted to the standard F is a toggle-link k, to which is pivoted a toggle-link Z, which linkl is prolonged to form a handle m. This link Z is also pivoted to a platform or cross-bar K, which platform is slotted for the reception of the lower edge of the pendulum-ball and provided with a guide-rod n, (shown in dotted lines in Figs. & and 6,) which works in the bore of the standard F.

Supposing the parts to be in the position shown in Fig. 4 and it is desired to lift and clamp the pendulum-ball, the arm on is thrown to the right, thereby bringing the toggle-links in line with each other, causing the platform K to lift the ball. As the platform K c011- tinues to rise the parts get in the position shown in Fig. 6, wherein the ball is shown as Lil :2 are,

lifted by a platform ii and gripped between the platform K and the upper cross-bar ll of the yoke G.

What I elaim, and desire to secure by Let;- ters Patent, is-

1. A pendulunvsupporter eonsistiu of a eombined lifting and elainpi ugf means .lor lifting and clamping the pendulum to hold the same from moving.

The combination of an upper cross-bar and a lower cross-bar or platform, and means for raising or lowering the said lower cross;- bar or platform, whereby the lower rrosabar or platform will raise the pendulum-ball and bring it against the upper crossbar, whereby the pendulum-ball will. be held between the eross-bars.

ii. A penduluni-supporter comprising the combination of a stationary upper eross-bar, with an up and down moving lower cross-bar, whereby the rising eross bar will lit't the said pendulum and force it agail'ist the upper eross bar, whereby the pendulum will be held be tween the eross-bars.

l. A pendulum litter and supporter comprising the eombination of a plurality of slotted cross-bars, the lower of whieh. is movable, and means for raising andv lowering thelower cross-bar, whereby the pendulum will be gripped by the slotted portions of the bars.

5. The combination 0t an upper cross-bar, a lower eross bar, and means for raising and lowering the lower cross-bar to raise and grip the pendulum comprising one or more pairs of toggle-links and an operatiug-lerer there for, substantially as described.

ti. In a pendulinn-supporter, the eonlhination of a stationary part located above the pendulum-ball and adapted to be engaged by the said pemlulnm-ball, a movable part lo- Gated below the said peiuflnlijim -ball and adapted to engage the said peiululnni-ball to raise the said pendulum-ball. and l'orre it against; the stationary part, and nneans for raising and lowering the movable part in a \ertieal direction whereby the NH able part will lioree thependulnm against thestationary part, the said two parts eenstitnting a oombined means for raising the pendulum and gripping; the same to relieye the snimensions 'iring ot the strain of the weight of the perv dulu'm-ball.

7. fin auxiliary pendulum snpporting deriee, eomprisin; pendulinnball-grasp]ng de- \iees arranged to grasp and hold the penduluin-ballandtolil'tthosamesothattheweight ot the pemlulunrball will be supported by the said penduluindiall-grasping deyiees.
