WALTER J. HERSCI-IEDE, or CINCINNATI, OHIO, AssIGNoR TO THE nnnscnnnn HALL CLOCK COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO.
CHIME-STRIKING HAMMER.
Specification of Letters Patent.
Patented Nov. 21, 1916.
Application filed July 31, 1915. Serial No. 42,874.
To all whom it may concern Be it known that I, WALTER J. HER- SGHEDE, a citizen ofthe United States of America, and resident of Cincinnathcounty of Hamilton, State of Ohio, have invented certain new and useful Improvements in Chime-Striking Hammers, of which the following is a specification.
This invention relates to improvements in chime striking hammers and particularly to hammers for chime clocks, in which it is usual to employ a leather covering for the hammer face for the purpose of cushioning the blow given the chime by the hammer, in order to prevent the metallic sound of the metal hammer striking the metal chime.
An object of my invention is to produce a hammer for striking chimes, in which im proved means are employed for securing the leather cushion at the end ofthe ham- A further object is to produce an improved chime striking hammer in which means are employed for positively centering, and maintaining the leather cushion taut at the end of the hammer with a uniform tension, so that the character of the blow struck by the hammer will always be uniform.
A further object is to produce an improved chime striking hammer in which the character of the blow struck by the hammer will be unaffected by changes in weather conditions.
These and other objects are attained in the hammer described in the following specification and illustrated in the accompanying drawings in which;
Figure 1 is a view of the back of the hammer. Fig. 2 is a view of the side of the hammer. Fig. 3 is a view of the front of the hammer. Fig. 1 is a sectional view taken on the line lt of Fig. 1, certain interior parts being shown in elevation for convenience of illustration. Fig. 5 is a view similar to Fig. 4 with those parts shown in section which are shown in elevation in Fig. 1. 4
The hammer embodying my ,invention consists of an internally screw threaded collar 6, having an externally screw threaded plug 7 located therein, a leather cushion 8 secured in position by the plug and collar, a mounting spring 9, a washer 10, and a screw 11 passing through the washer, the
adjacent to the end of the internally screw threaded portion, to a point adjacent to the striking face of the hammer, at which point this tapered surface 11 is provided with a greater taper to produce a feather edge betweenthe internal tapered surface 13 and the external tapered surface 15. The plug 7 is provided with screw threads for a portion of its length, substantially equal to the distance of the screw threads in the collar 6, and a straight cylindrical Surface 16 for 5 a portion of the remainder of its length, the plug terminating in a tapered surface 17 adjacent to its substantially flat end 18, the tapered surface and the flat end forming a truncated cone. of the plug andthe internal tapered surface 13 of the collar are adapted to cooperate with one another in compressing the edges of the leather cushion 8 placed The tapered surface v over the head of the plug 7, and to simultaneously stretch the leather and maintain it tightly against the end 18 of the plug 7, to produce a cushion having a cup-like formation. The mounting spring 9 for the hammer is provided with an aperture 20 Y and the plug 7 is provided with a registering aperture WlllCll 1s screw threaded, the screw threads being provided to receive the screw 11 which passes through an aperture 21 in the metal washer 10 and an aperture 20 in the spring for the purpose of securing the head comprising the collar 6 and plug 7, as well as the back comprising the washer 10, to the spring. The plug 7 is provided with a slot 22 at its screw threaded end to receive the blade of the screw driver so that the plug may be secured Within the collar 6 for the purpose of securely fastening the leather cushion in position against the tapered surfaces 13 and 17 and the end surface 18 of the plug.
By means of my improved chime striking hammer I have overcome the objections found in hammers heretofore employed,
which utilize a turned metal head having a knob formed on one end for receiving the leather cushion, with a groove formed on the knob for receiving a binding wire which passes over the leather for securing it in position. Such a construction is somewhat of a makeshift and renders the leather covering liable to bag or become too loose upon the knob with no means of tightening it properly. In my improved construction it is merely necessary to remove the head comprising the collar 6 and the plug 7, and to tighten up the plug in the collar by means of a screw driver located in the slot 22. The metal washer 10 is preferably made somewhat thick for the purpose of giving it weight to render the hammer sufficiently heavy to strike the chime properly. In addition to this the heavy washer balances the hammer properly on each side of the spring.
In driving plug 7 into place it will not split and will stretch the leather evenly, and will neither warp nor become loose nor swell and change the thickness of the leather covering it. This results in a uniformity in character of strike, and produces tones of unvarying quality.
Having thus described my invention, what I claim is:
1. In a chime striking hammer the combination of a collar, a metal plug mounted in the collar, a leather cushion mounted on the plug and held in position by the collar, a handle, a heavy metal washer, and a screw mounted in the plug adapted to secure the handle between the plug, collar, and the washer.
In combination in a chime striking hammer, a hammer head, a handle, a heavy washer, and means adapted to secure the handle between the washer and the head, said head comprising a collar having an inwardly tapered inner surface, a plug located in the collar and having an externally tapered surface adapted to cooperate with the tapered surface of the collar, a leather cushion mounted on the plug and held in position by the cooperatingtapered surfaces of the plug and collar, and means formed externally of the plug and internally of the collar adapted to secure the plug and collar together.
3. A chime striking hammer comprising a hammer head, a handle, a heavy washer, a means adapted to secure the handle between the washer and head, said head consisting of a collar having an inner surface tapering inwardly to its outer end, a plug having an inwardly tapering outer surface, a cushion located between the tapered surfaces of the plug and the collar, and means for securing the plug and collar together to clamp the cushion in position.
4. In a chime striking hammer, a hammer head consisting of a headed plug hav ing an inwardly tapering outer surface, a collar having an inner surface tapering inwardly at its outer end, a cushion located between the tapered surfaces of the plug and collar, and means for securing the-plug and collar together to clamp the cushion in position over the head of the plug.
In a chime striking hammer, a hammer head consisting of a collar having an inner surface tapering inwardly at its outer WALTER J. HERSCI-IEDE.
