SPECIFICATION formingpart of Letters Patent No. 688,965, dated December 17, 19
Application filed January 9,1901. Serial No. 42,619. (No model.)
To wZZ whom it may concern.-
Be it known that I, WILHELM PEISKER, a subject of the Emperor of Germany, and a resident of Berlin,Germany,.have invented certain new and useful Improvements in Phonographs, of which the following is a specification.
My invention relates to means for holding the diaphragm-frame in place; and it consists in the features andcombinations of parts hereinafter described, and particularly pointed out imthe claims.
The invention is illustrated in the accompanying drawings, in Which Figure 1 is a side elevation; Fig. 2, a plan view of the diaphragm-frame; Fig. 2, a sectional view of the same; Figs. 3 and 3 similar views of a modification. I
In Fig. 1 a tube-socket w is held by afeedarm a. In the socket a shell orlsound feeding tube y is arranged so as to permit up-anddown movement, and the lower extremity of said tube is journaled on a movable rail g. By means of this arrangement'the sound jackets or diaphragms illustrated in Figs. 2 and 3 may be temporarily connected to or exchanged on the rail. In the diaphragm, as represented in Fig. 2, m is a frame, to the rear end of which two parallel clamps Z Z are connected.
By the spring action of these clamps the frame 'm is held below the feeding system shown in Fig. 1 by itsrear side.
ing '0 into secure connection with the sound transmission or feed y.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
- 1. In combination with means for transmitting the sound, a diaphragm-frame having projecting spring-clampson its rear side, and means for engaging the said clamps and holding the diaphragm in, place, substantially as described.
2. A diaphragm-frame having means on its rear side to attach the same to a support said means having a sliding connection with its support, substantially as described.
3. In combination with a supporting-arm, a diaphragm-frame having the attachingclamps and a stop 15 to position the diaphragm in relation to the arm, substantially as described.
In witness whereof I have hereunto set my hand in presence of two Witnesses.
WILHELM PEISKER.
