CLOCK Filed Aug. 6, 1931 Patented Mar. 1, 1932 UNITED STATES PATENT OFFICE cLocx Application filed August 6, 1931.
The present invention in its broader as pects has a wide and varied range of utility in connection with various classes of measuring apparatus, but relates particularly to it chronological and horological instruments. It finds its preferred embodiment in a clock of the electrically driven type. While useful in connection with electric clocks using impulse motors, it is particularly effective for embodiment in a synchronous motor type of electrical clock whether of the hand started or of the self-starting variety.
The synchronous motor clocks of the hand started character run silently and continuously unless the power which supplies the motor is cut off. When the circuit is re established, the motor will not operate the clock until such time as a starting button is grasped and the motor spun so that it comes back into phase with the alternating operating current, whereupon the clock will run until another current break occurs.
One of the difficulties with the clocks of this character is the fact that inasmuch as their normal operation is silent, there is no cessation of ticking to indicate when the clock has stopped.
The use of special signal mechanisms effectively to apprise of the stoppage of the clock,
nections to operate and restore the signals.
Ordinary sweep hands while simple, are frequently ineffective, for such hand may stop nearly or quite in alignment with either the minute or hour hand of the clock and in casually glancing at the dial, one frequently fails'to note anything except the position of the hour and minute bands, which obscure 40 or render inconspicuous the stopped sweep hand which may lie over or under one of them.
An object of the invention, therefore, is to provide a clock of the character described above, in which the position of the sweep hand always will be readily observable and its stoppage will be immediately apparent to any one glancing at the clock.
According to the invention, the sweep hand of the clock is of conformation that can at no time coincide with either hour or minute Serial No. 555,427.
hand, and that enhances the distinctive and aesthetic appearance of the clock. In a preferred embodiment the sweep hand comprises a short radial segment having integral therewith a trailing arcuate segmentintegral with the trailing end of which is a second outwardly extending radial segment. It is with in the scope of the invention, however, to provide a radial sweep hand in combination with modified hour and minute hands.
Another object is to provide a clock of simplified construction in which the use of the circular dial is completely eliminated, and there is no need for using bezels or other special frames with which the crystal is preassembled.
Another object is to provide a clock and a clock casing of simple, practical, rugged and durable construction, which by novel correlation of hands and numerals will be particularly easy to read, and yet afford a distinctive and ornamental appearance.
The casing which houses and encloses the electric motor and the gear train which constitute the clock works, is provided with a front face totally devoid of any indicia and. the crystal which ordinarily is used to protect the hands is encircled and may be clamped into place by a numeral carrying ring attached directly to the front surface or panel of the clock casing. By virtue of this arrangement, the need for special dials carried by the clock works is completely obviated and the construction of the casing itself is materially simplified, being, if desired, of two pieces of material, one piece constituting a removable back, which may be readily detached for purposes of inspecting or repairing the works.
Preferably the numeral carrying ring is of molded material, having molded therein the securing devices which connect it with the casing, and having an inner rim molded to conveniently hold the crystal in position. The need for preassembling the crystal into a bezel or for using a dial is thus avoided and the resulting structure, while having a distinctive and unusually simple appearance, facilitaes reading the time of day by a quick glance, the numerals being larger and more \videl spaced about rather than within the perip iery of the crystal.
The invention may be more fully understood from the following description in connection with the accompanying drawings, wherein Fig. 1 is a perspective view of a clock embodying the invention;
Fig. 2 is an enlarged side elevational view of the clock with parts broken away and in section on the line 2-2 of Fig. 1;
Fig. 3 is a rear face view of the numeral carrying ring; and
Fig. 4 is a transverse sectional detail on the line 44 of Fig. 3.
= The clock casing indicated generally by the reference character C may be fashioned of any suitable material, the casing front 2, casing bottom 3, top 4 and the straight sides 5 being integrally formed. The casing may be of molded material or of wood or of any other suitable substance. For illustrative purposes, I have shown the casing top curved for tangency with sides 5, and substantially in conformity with the curve of the circular numeral bearing ring 18 which is aflixed to the front of the casing.
Near the upper end of the front or panel of the casing, the latter has a circular cavity 6 sunk therein, the surface of which is shown flat but may be slightly convex and presents a countersunk disk unitary and preferably integral with the panel. The shoulder 7, determining the periphery of the cavity is cut away near its outermost part to define an outwardly facing ledge 15 forapurpose which will more fully hereinafter appear.
Centrally of the cavity 6, the casing in front is provided with an opening 8 through which the concentric minute hand, hour hand and tell-tale hand shafts extend. These shafts in the present instance, are designated by the reference numeral 9.
A numeral ring 18 encircles cavity 6 and may on the inwardly sloping face thereof be provided at regularly spaced intervals with numerals 22 indicating the hour. The ring may be of any appropriate material. and the numerals may be displayed thereon in any of a wide variety of ways. Preferably, however, the ring is molded of material contrast-ing with that of the clock casing and the numerals are molded in intaglio or relief and filled in with enamel.
Also embedded in the ring 18 during this molding operation, are preferably the heads 19a, of securing devices such as 19, which preferably comprise bolts projecting rearwardly from the face of the ring and adapted to enter or pass through corresponding openings 197) in the clock case. Nuts 21 threaded upon the extremities of the bolts and pressing against the inner face of panel 2 serve to clamp the numeral ring against the front face of the panel.
Observing the ring in cross-section in Figs. 2 and 4, and-noting the back plan view in Fig. 3, it will be seen that the ring is of generally convex cross-sectional shape having spaced annular concentric bearing surfaces 18a and 18?), at its rear face which lie flatly against the clock casing, concentric with but radially beyond the circular cavity 6. At the points where the securing devices 19 are molded into the ring, the two flattened portions 18a and 18b, may be connected by cross webs such as 180 which afi'ord firm anchorage for the heads of said devices.
To protect the hands from inadvertent injury and to seal the casing against the entry of dust and dirt, a convex crystal 16 of conventional form may be utilized. The edges of this crystal preferably rest upon a yielding packing ring or gasket 15a, supported on ledge 15 and the crystal is retained in place thereagainst by suitable fastening means coacting with its rim. Preferably, the ring is formed at its inner edge with an integral head or flange 23 of hook shaped cross section adapted to press lightly against the edge of the crystal; thus to force it into engagement with 'the packing 15a and thus to hold it in place, and to frame the edge of the crystal, all without the need for any auxiliary crystal securing means.
The hour hand 11, the minute hand 10 and the tell-tale hand, indicated generally at S, may be driven from the clock works (not shown) through any convenient or conventional train of gears. These hands contrast in color with the front face of the clock casing over which they travel and they all read on the numeral bearing ring 18.
The clock works are neither illustrated nor per se claimed herein, but as suggested above, a synchronous, non-self -starting electric motor may be used to drive the hands through any suitable gear train. When the motor stops, it may be hand started by spinning the hand-starting button B, which projects rearwardly through the casing back 25, at any suitable position not occupied by the conventional setting button S.
This casing back is also preferably formed of molded material, fitting within the clock casing and lying against one or more integral ledges 3O molded in the casing. The back is held in place by screws or equivalent securing devices 24, which may enter tapped sockets 24a in the casing.
The minute and hour hands of the clock are conventionally shown as radially disposed with respect to the circular numeralcarrying ring. and, therefore, to carry out the principles of the invention. the tell-tale hand includes at least some non-radial portion. Illustratively, I have shown this hand as an integral metal stamping consisting of a radial inner section 12 and a radial outer section the hour hand or minute hand or both that it will be concealed from view or become inconspicuous. Even a casual observer glancing at the clock will immediately notice whether or not this hand has stopped moving.
As suggested above, a wide variety of expedients might be resorted to for eliminating the possibility of coincidence of the sweep ham with either of the other hands upon stoppage of the clock although the specific construction shown in the drawings is preferred. The sweep hand might be of zig-zag formation or of curved formation or might be of truly radial formation while the hour and minute hands were provided with offsets or were curved. In all embodiments within the scope of my invention, insofar as the same relates to clock hand construction, the offset portion is a part of the main length of the hand which must be traversed in running the index finger from the mount of the hand along the structure of the hand to the single pointer end thereof. From another point of view a substantial part of the main length of the tell-tale hand is laterally displaced with respect to a. straight line joining the mount and the pointer end of the hand. It is important so to construct the hands of the clock that in no position will it be possible for the sweep hand to lie in its entirety directly in coincidence with one or both of the other hands.
It will particularly be noted that the numeral ring in the preferred embodiment protrudes outwardly for a substantial distance beyond the plane in which the hands are located and materially beyond the periphery of the crystal. The hands preferably are lodged in a cavity in the panel, so that they move in a plane considerably below that of the numeral ring. By this arrangement the clock is afforded a uniquely attractive appearance, affording also greatly enhanced visibility and readability as compared with time pieces in which the numerals lie substantially below or at the plane of the hands.
The mode of application of the numeral ring renders possible effects of contrast attainable with difiiculty where the parts are unitary and, moreover, as pointed out brings about the facility of application of the crystal retained in position'by the inner rim of the numeral ring. The clock is devoid of any dial, the disk over which the hands move being blank and all three of the handsthe hour, the minute and the tell-tale hand, being co-ordinated with the numeral win Itwill thus be seen that there is herein described apparatus in which theseveral features of this invention are embodied, and
which apparatus in its action attains the various objects of the invention andis well' suited to meet the requirements of practical use.
As many changes could be made in the above construction, and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
