KLUMAK BROTHERS in VIENNA. Innovations in repeater pocket watches.

Patented in the German Empire on March 31, 188a.

The purpose of this invention is to improve the mechanism in clocks that have both the hours as well as striking and repeating the quarter hours.

Fig. Ι is the basic pattern of the gear train, namely ABCD are the wheels of the movement and EFG HI those of the striking mechanism. K is a lever arm whose drop is limited against the pin L and which, attached to a shaft, is lifted by the lifting pin wheel F , M is a passage in the board.

Fig. 2 is the basic outline of the cadrature and the pointer mechanism; O and N are two rakes that rotate around the same axis; In Fig. 5 this arithmetic part is shown alone for a better overview. . On the rake N, Figure 5, an arm is screwed in and around this screw easily rotatable; a spring η gently pushes this arm downwards. If the rake section falls out from right to left, arm m is raised at 11, and both rakes can now be separated, more or less far away from their position. When the rake N is returned by the creator (not shown in the drawing for the sake of simplicity), m falls back down at 11 and takes the rake O with it. On the rake O is the resting pen for the Creator.

T in FIG. 2 is a collapsible buckle, S is a release arm which, together with the spring W, forms the jumping release. T and S rotate about the same axis so that when S bounces up by bouncing against T at 15 T , no friction is caused. P is the quarter stairs, connected to a change wheel; in Fig. 6 this part is drawn in detail for better clarity. B, Fig. 6, is the drive shaft of the hour wheel. P is the staircase in which the release pins 5 and 6 are located. At 4, P is connected to the change gear 2, and both are riveted onto a tube 3 which is rotatable on the shaft B. 7 is a long pointer tube, rotatable about the shaft B \ between 7 and P, there is a small spring 10 which presses the two parts 7 and P apart. In P a pin 9 is fixed and in 7 a hole is drilled which receives the pin 9. If 7 is turned with the pointer, P and the pointer also turn.

Fig. 3 and 4 show the back plate with the gongs and the hammer section. /, Fig. 4, is a shaft on which the lifting arm k is riveted; furthermore, the lever f is fastened on the same shaft like a hammer bar of ordinary striking clocks. Z is a right-angled arm which rotates on a cadrature pin 13 on the one hand in the horizontal direction, as indicated by the arrow at 12 in Fig. 4, but on the other hand can also be lifted in the vertical direction because it has a hinge-like connection at y. This pivot point falls on the axis of the hammer shaft / _; The arm Z also carries two pegs d and e, which reach close to the gongs when the arm is in the normal position, and which are attached in such a way that, when z. B. the peg d is above the gong h and by lifting and dropping the gong h makes sound, the second peg e hits the air. One is enough

Claims (6)

Slight displacement of the arm Z at 12 in the direction of the arrow in order to change the position of the pegs so that peg e hits the gong spring i and d in the air. Finally, a weak spring always pushes arm Z horizontally into its normal position as shown in the drawing, while another spring above or below the hinge / the falling of the pegs can weaken or strengthen the falling off of the pegs as required. It can be seen that without departing from the essence of the invention, the shape or size of the arm Z can be varied; so can z. B. the same can be provided with one instead of two pegs, in which case only a larger lateral displacement of this arm Z is necessary. The function of the racket is now carried out in the following way: every quarter of an hour the release arm S is thrown against the drop-in buckle * T, the rakes ON fall against their stairs Q and P, which regulate the number of strokes, and the released creator (in the Drawing not shown for the sake of clarity) returns the rake N, while the lifting pinwheel F lifts the arm K and thus also the arm Z and lets it fall; the gong spring h will sound for every beat until rake N at χ shifts arm Z in the direction of the arrow so much that the gong spring * will sound with each of the following beats. At the same time as the displacement just described, the arm m of the rake N also falls into the teeth of the rake O, so that it is carried along and finally the movement of the hammer mechanism is inhibited by the creator pressing against the resting pin on the rake O. By pushing up the arm η, the striking mechanism can be made to repeat at any time. Patent claims: 1. The arrangement of the quarter stairs P with the change gear 2 and the pointer tube 7, as shown in FIG. 2. The arrangement that the release lever 6 ¹ and the lowering buckle T rotate on one and the same cadrature pin, whereby friction at 15 is avoided when the lowering buckle T is lifted by the arm .S. 3. The arrangement of the two rakes ON with the arm m and the displacement surface x, as shown in FIG. 4. The attachment of the two springs R, Fig. 2, which consists of a wide spring split in the middle, which thereby becomes two springs, one of which pushes the rake O, the other the rake N and only with one Screw is screwed to the board. 5. The arrangement of the pointer mechanism, as can be seen in Fig. 2, in that both change gears go under the hour clock α and on this only a small cock b is screwed with the screw c , in which the ■ The upper journal of the change drive is running. 6. The attachment of the arm Z, as well as the manner of its displacement for the purpose explained, which makes it possible, in conjunction with the other arrangements mentioned, that the blows emitted by a single drive now on one, now on the other gong or bell can be judged, one of which marks the hours, the other the quarter of an hour. For this purpose I sheet drawings.
