Description
PATENTED SEPT. 17, 1907.
A. P. KOON. CLOCK ADJUSTER. Arrmoulol nun mu :0. 1901.
UNITED STATES ANDREW P. KOON, OF SHERIDAN, ARKANSAS.
CLOCK-ADJUSTER.
Specification of Letters Patent.
Patented Sept. 17, 1907.
Application filed July 20,1907. Serial No. 384,783.
To all whom it may concern:
Be it known that I, ANDREW I. KooN, a citizen of the United States of America, residing at Sheridan, in the county of Grant and State of Arkansas, have invented new and useful Improvements in Clock-Adjusters, of which the following is a specification.
This invention relates to clock adjusters, and one of the principal objects of the same is to provide simple and etlicient means for adjusting the pendulum sup port to an accurate vertical position irrespective of the inclination of the clock frame.
Another object of the invention is to provide means for adjusting the pendulum support of a clock so that the pendulum will oscillate uniformly upon opposite sides of the support whether the clock frame is supported upon a horizontal or slightly inclined support.
These and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which:
Figure 1 is a front elevation of the pendulum mech anism and the escapement mechanism of a clock, and showing an adjuster made in accordance with my invention. Fig. 2 is a perspective view of my clock adjuster.
Referring to the drawing for a more particular description of my invention, the numeral 1 designates the supporting frame for the clock mechanism, said frame being provided with an extension 2 having an offset portion 3.
It will be understood that my clock adjuster may be connected to clock frames of various structures, and that the extension 2 may be connected by any suitable means to the clock frame upon either side of the center thereof.
The clock adjuster consists of a flat brass or other metal bar 4 having at its upper end a post or stud 5 in which is formed a slot for securing the pendulum spring 6 therein. Connected to the lower end of the spring 6 in the usual manner is a'pendulum rod 7 provided with a hook 8 at is lower end. The bar 4 is provided with a perforation 9 for a screw or stud 10 and a washer 11 is fitted to the screw 10 and the latter is connected to the clock frame 1. On the lower end of the bar 4 is a hook 12 and extending at an angle to the bar a is an arm 13 upon the outer end of which is a slotted head 14, the slot 15 in which is formed on the arc of a circle of which the screw 10 is the center. A milled binding screw 16 is provided with a shank 17 which extends through the slot 15 and is adjustable in a threaded aperture in the offset portion 3 of the frame 1. The pendulum ball 18 which may be of the usual construction is provided with a supporting rod 1 having the usual slotted loop 20 at its upper end for engagement with the hook 8 on the rod 7. The escapement wheel 21is of the usual construction and the verge 22 and the verge rod 23 are also of the usual construction, the loops 2-1 of the verge rod encircling the pendulum support 7 in the usual manner. The loop 24 works in front of the pivot screw 10. v
The operation of my invention may be briefly described as follows: A clock provided with my adjuster may be set upon a mantel or other support which is not g in a true horizontal position, and in order to adjust the clock, irrespective of the inclined position of the clock frame, the set screw 16 is loosened and the pendulum 18 is removed from the hook 8 and the loop 20 is en gaged with the hook 12 of the bar 4. The pendulum is then swung upon the pivot 10 and when it comes to a dead stop, the pendulum hangs in an exactly vertical position, irrespective of the position of the clock frame. The binding screw 16 is then tightened and the pendulum is removed from the hook 12 and engaged with the hook 8. As thus adjusted the clock will run smoothly and the pendulum will have an equal oscillati n on opposite sides of a central vertical line. It is to be understood, of course, that each time the clock is moved from one place to another, an adjustment is to be made, and that it is immaterial in which direction the clock frame inclines as my adjusting mechanism is capable of regulating the swing of the pendulum irrespective of the position of the clock frame.
My invention is of simple construction, can be applied to any pendulum clock, is quick and accurate in adjustment, and can be manufactured at small cost.
Having thus descr bed the invention, what I claim is:
1. A clock adjuster comprising a pivoted bar, a pen (lulum support connected to said bar, an arm extending at an angle to said bar and provided with a slotted head, and a hook on said bar for supporting the pendulum during the adjustment, and a binding screw passing through the slotted head for securing the same to the clock frame.
2. A clock adjuster comprising a pivoted bar carrying a pendulum support, means for connecting the pendulum to said bar, an arm extending at an. angle to said bar, and provided with a head having a curved slot therein formed on the arc of a circle of which the pivot is the center, and a binding screw for holding said head in adjusted position.
3. A clock adjuster comprising a pivoted bar, pendulum supporting means connected to said bar. means whereby said bar may be adjusted to a true Vertical position, and means for holding said bar in such position, to regulate the swing of the pendulum.
In testimony whereof, I affix my signature in presence of two witnesses.
ANDREW P. KOON.
