WATCHMANS CLOCK.

SPECIFICATION forming part of Letters Patent No. 71 1,712, dated October 21, 1902,

Application filed November 9, 1900. Serial No. 35,892. (No motleLl T0 at whom it may concern.-

Be it known that I, ALOIS BEYER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Watchmens Clocks, of which the following is a full, clear, and exact specification.

My invention relates to that class of clocks usually carried by watchmen from post to post or station to station and utilized by them in connection with keys located at the various posts or stations for punching or otherwise indicating in a dial or suitable impressionsurface the time each station or post was visited; and my invention has for its primary object to provide an improved construction of clock of this character which shall have means for effecting the punching or marking of the dial or other impression-surface without resulting in the strain of such action being borne by the key while the latter is being either turned or oscillated.

A further object of my invention is to make a part of the key serve as the punch or marker, but to cause its operation by other means more capable of withstanding the strain liable to distort or injure the key.

With these ends in view my invention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference to the accompanying drawings and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a plan view of a part of a watchmans clock, the casing being removed, showing my improvements applied thereto. Fig. 2 is a perspective view of the combined key and die or marker. Fig. 2 is an enlarged detail perspective of the punch or marker. Fig. 3 is an end elevation. Fig. at is a transverse section taken on the line at i, Fig. 5. Fig. 5 is a side elevation. Fig. 6 is a perspective view, on an enlarged scale, with a portion broken away and the dial omitted; and Fig. 7 is a section on line 7 7, Fig. 5.

In illustrating my invention in the accompanying drawings I have omitted all of the I clock mechanism and only shown suificient parts of the prior apparatus to enable an un derstanding of my improvements.

1 represents the dial or impression-surface, which may be of the usual or any suitable form and supported and held in the usual or any suitable manner. This dial is rotated by the clock mechanism (not shown) over a punch, die, or other marker, which is actuated to produce an impression on the dial, and thus indicate the time when the watchman visited -the post or station, having a key for effecting the operation of such die or marker. In the example of my invention shown in the drawings, 2 is the punch, die, or marker, and it is formed directly on the edge of the key 3, the construction of which in other respects will of course be dependent upon the fancy of the particular manufacturer, but in any event must be such that the die or marker cannot be actuated unless the key be properly and fully inserted.

at represents the keyhole, which is formed in an end plate 5 and which is complementary in shape to the cross-area of the key, in the form shown such cross-area being substantiall y L-shaped and composed of the body portion of the key and a short side flange 6, formed along the lower edge thereof. The plate 5 is formed'on or formed integrally with a table '7, between which and a female die 8 passes the edge of the dial 1, and which table 7 is provided with an aperture of suflicient size and proper dimension to permit the die or marker 2 to rise through the table and make an impression or puncture in the die 1 after the key has been inserted and forced upwardly toward the dial. Just below the table 7 is arranged a receiver 9 for the key, and this receiver has a passage 10 complementary in shape to the cross-section of the lower edge of the key and is arranged opposite-the keyhole 4, so that the key may be inserted through the keyhole and into the receiver 9, with its upper edge resting in the slot or aperture '7 in the table 7. The receiver 9 is movable and provided with means for forcing it toward the dial, and consequently lifting the key and pressing the marker or punch 2 against the dial, which in perforated cars 11, which are pivoted on a rod 12, secured in the end plate 5 and an opposite end plate 13, formed on or secured to the table 7. As a means of actuating the receiver 9 to make it perform its described function I provide a rod or shaft 14:, which has its ends journaled in the end plates 5 13 and is provided in one side with a V-shaped groove 15, in which the corner of the receiver 9 rests. The exterior end of the shaft 14 is provided with a key-post or squared end 16 for the ap plication of a wrench or key 17, whereby the shaft 14, which when formed in the described manner constitutes an eccentric, may be caused to force the receiver 9 upwardly toward the dial, and consequently force the die or marker 2 against the die and produce the impression, and all this without subjecting the key 3 to any strain while being twisted or oscillated, and, in fact, subjecting it to no strain excepting that which is necessary to transmit the pressure of the receiver to the dial. The receiver may be returned automatically to its former position and held in engagement with the shaft 14 bya coil or other suitable spring 18. This upward movement of the receiver 9 cannot take place, however, until the key has been entirely inserted to its proper position, because it is obvious that while the flange 6 of the key remains in the side notch of the keyhole tthekeycannot rise,and as aconsequence the dial cannot be punched at any point excepting that for which the key was intended. Hence it is obvious that by placing the dies or markers 2 at different points throughout the lengths of the various keys the punch or mark made by each key, although similarin form to every other punch,will have a distinctive location on the face of the dial. As a consequence, therefore, all of the keys may be the same in cross-section, differing from each other only in the location of the punch 2 with reference to the length of the key. If desired, the female die 8 may have separate cavities corresponding to the location of the various dies or markers 2 with reference to the length of the key, there being one key for each station or post and a corresponding number of the female dies or cavities 8, and the female dies 8 may be type-matrices, as shown in Fig. 7, and the punches 2 may be formed with corresponding type, as shown in Fig. 2, so that by providing each post or station with a separate letter or number the punches or marks made on the dial may be readily distinguished from each other.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is
