TOWER CLOCK.
APPLIGATIOH EIL ED MAY 13, 1901 Wm T! F X-M y EDWARD ROWE, OF INDIANA, PENNSYLVANIA TOWER-CLOCK.
Specification of Letters Patent.
Patented Nov. 26, 1907.
Application filed Kay 9. 1901. Serial No. 59.482.
To all whom it may concem:
Be it known that I, EDWARD ROWE, a citizen of the United States, residing at Indiana, in the county of Indiana and State of Pennsylvania, have invented a new and useful Improvement in Tower-Clocks, of which the following is a specification.
My invention relates to an improvement in tower clocks, a primary object being to provide means whereby the time may be determined with accuracy at night, at a much greater distance than is ordinarily possible; other objects perhaps of only slightly less importance being economy in the cost of installation, and operation.
\Vith the foregoing objects in View my invention consists in an arm ement of three incandescent lamps, prefera ly of diilerent colors, and if desired, although not necessarily, of different candle ower, one carried by each hand of a clock an the third located at the center post, so that the time is determined solely by the triangular relations of the three lamps, irres ective of any illumination of the clock dia or figures, there being no intention, on the contrary of lighting either dial or figures.
My invention further consists in means for extending the len th of the hands regardless of the diameter of theclock dial so that the direction of the hands may be seen at greatly increased distances and the time of night determined with perfect accuracy.
My invention still further consists in certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims.
In the accompanying drawings, Figure 1, is a view in longitudinal vertical section, showing my improvements applied in connection with the motion, work of tower clock, parts being in elevation, Fig. 2, is a front view, Fig. 3'is a view of an extension arm, Fig. 4 is a view of one of the lamps, and Fig. 5 is a view of the lam socket.
A, represents a clock d ial upon which are arranged the usual figures, and B and C are the hour and minute hands, respectively, secured on hol' ow concentric shafts 1 and 2 and operated by the customary motion work s iown in a general way in Fig. 1, although not described in detail because well known and no part of the present invention.
Incandescent lamps 12 and 14 are carried,
respectively, by the minute and hour hands of the clock, and a third centrally located lamp 13 over the center post, is preferably carried also by the minute hand, and disposed as it is parallel therewith, and to outward view in alinement with the minute hand lamp, it gives an attenuated effect and appearance to the minute hand thus rendering its identity unmistakable at a glance, even at a long distance. These lamps might of course all be the same color and candle power but referably the minute hand lamp is red, the our hand lain green, and the center lamp yellow or white; and experiment has proven that the best results are obtained by about the following candle powers for the different lights, say six for the white or yellow, ten for the red and sixteen for the green or thirty-two in all. This hasbeen found to be the most satisfactory combination the red and white lights would partially obscure the green unless the ower of the latter about equaled or exceer ed that of the other two combined. By actual test this thirty-two candle power, thus arranged, or the current required by two ordinary sixteen candle power lamps is suflicient to show the time one and onehalf miles. These lamps may be connected to the clock motion works in any approved manner. By preference however an extension arm 3 of wire or ilat sheet metal is employed as it may be bent and adjusted to allow lamps to pass each other as well as projections, etc, in the revolution of the hands. By means of them there would be no difficulty in making a five l'oot dial appear to be a ten foot one by simply re ulating the length of the extension arm. ese extension arms may be secured to the hands by screws as shown in Fig. 3, and at their outer ends they are provided with a clamp 5 adapted to enter the circumferential grooves 6 formed in the lamp sockets 7 whereby to securely hold the lamp. Of course the lamps might be secured directly to the hands but as distance is an object, the purpose is to lengthen out the hands or to give them the appearance of greater length so that they can be seen at greater distances than would otherwise be possible. Each. hand has a counterbalance 28.
The wires from the two lamps 12-and 13 pass through the center of the minute hand shaft 2-to the binding posts on the contact l rings 15, 15, which latter are insulated from the outer shaft 1, upon which they are mounted by means of the rubber or Wood insulators it). And the wires 17 from the lamp lpass through the groove 18 in the outer hour hand shaft 1 to the binding posts on the rings l9, 19, which latter are also mounted on shaft 1 with insulators 2G interposed therehetween. Operating in connection with the ring contacts and 19, are the brushes 21, 21, and 22, 32, and these are secured at their opposite ends tothe ends of fuse blocks 23, 24, the current passing through the electric Wires and 26 from and to the genera tor.
From the foregoing it will be seen that the only light necessary are the three described located at the outer ends of the hands and at the center of the dial, the time being indicated at night by their relative positions, or in other Words the positions oi the two hand lamps, ivith respect to the center lamp, aided perhaps by the diii erentcolored lights. The dial is not lighted at all, unless incidentally T the three lamps, but not at all as a part 1 i I o scheme of time indicating, as the dial would be necessary but for day use when, of course the lamps not lighted. iln this Way only a comparatively small candle power is required. Thus the cost of operation is reduced to a minimum, and the initial cost of installation is trifling as compared with the dial illuminating system commonly in vogue. Again the present system is applicable to tower clocks now in use without the necessity of insulating the entire mot-ion work and all its connections.
It is evident that slight changes might be made in the form and arrangement of the parts described without departing from the spirit and scope of my invention, and hence i do not Wish to limit myself to the exact construciion herein set forth, but
Having thus fully described my invenerases tion, What i core by Let? l l.
