UNITED STATES PATENT OFFICE.

WALTER J. HERSCHEDE AND CHARLES CoIIAN, 0F CINCINNATI, OHIO, ASSIGNORS To THE HERSCHEDE HALL CLOCK COMPANY, or CINCINNATI, OHIO, A CORPORATION OF OHIO.

TENSION-ADJUSTER FOR THE SPRINGS OF CHIME-HAMMERS.

Application filed July 2, 1917.

To all whom it may concern:

Be it known that we, WALTER J. HansCHEDn and CHARLES CoHAN, citizens of the United States of America, and residents of Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Tension-Adjusters for the Springs of Chime-Hammers, of which the following is a specification.

A11 object of our invention is to produce a compact and simple means for adjusting the tension of the hammer mounting springs of ordinary tubular chime clocks, whereby the intensity of blow delivered the chime tubes may be regulated.

This and other objects are attained in the tension adjuster described in the following specification and illustrated in the accompanying drawing, in which;

Figure 1 is a fragmental elevational view of a tubular chime with a hammer positioned for use and having our improved tension adjuster connected therewith.

Fig. 2 is a view similar to Fig. l, but showing the parts in the position assumed before the tension adjuster is'made operative.

vention I have shown the usual hammer mounting bar 3, which carries all of the hammers adapted to strike the usual series of tubular bells. A series of upwardly extending lugs 4, which are bent outwardly from the bar, are secured thereto so that their upper ends are in spaced relation to the springs 5 of the hammers. Each of these lugs is provided with an aperture internally screw threaded to receive an adjustment screwfi which is provided at its outer end with a winged head 7 for the purpose of rotating the screw to bring it to adjusted positions with relation to the lug and the spring and having a lock nut 8'mounted on the screw for the purpose of securing it in adjusted positions by bringing the lock nut into clamping engagement with the lug t. In Fig. 1 adjustment screw 6 has been brought to its adjusted position and lock nut 8 has been moved to lock the screw in this position. The hammer head 9 is thus brought to a position properly distanced from the Specification of Letters Patent.

In the illustrated embodiment of my in- Patented Jan. 4, 1921.

Serial No. 178,088.

tube 10 which it is adapted to strike. When ad ustment screw 6 is released by lock nut 8 and is moved to the position disclosed in Fig. 2, the spring 5 of the hammer is permitted to assume the position disclosed in Fig. 2 in which the hammer head is spaced quite a distance from the chime tube: By gradually advancing screw 6, spring 5 is pushed inward until head 9 is brought to a position such that when retracted by the hammer operating mechanism 11 it will upon its return, be caused to strike the tube 10 with the desired intensity of blow.

Having thus described our invention, what we claim is:

1. A tension adjustment for the mounting springs of chime hammers consisting of a spring mounting bar, a hammer mounting spring mounted on the bar, a contact device mounted near the attached end of the spring, and means for adjusting the degree of pressure of the contact device upon the spring.

2. Atension adjustment for the mounting springs of chime hammers consisting of a spring mounting bar, a hammer mounting spring mounted on the bar, a lug extending from the bar and having its end in. alinement with the spring, a screw mounted in the lug and having its end adapted to engage the spring, and means adapted to lock the screw in adjusted positions.

3. A tension adjuster for the mounting springs of chime hammers, consisting of a adapted to be brought into engagement with the lug to lock the screw tions.

In testimony whereof, we have hereunto subscribed our names this 30 day of June,

WALTER J. HERSCHEDE. CHARLES COHAN. Witnesses:
