SIEOIFIOATION forming part of Letters Patent No. 657,167, dated September 4, 1900.
Original application filed December '7, 1898, Serial No. 698,610. Divided and this application filed September 25, 1899. Serial No. 731,647. (No model.) I
698,510, and for which I have made applica.
tion for Letters Patent in Great Britain under No.20,754, dated October 1, 1898; in Germany, dated November 22, 1898, and in France under No. 279,115, dated July 24, 1899,) of which the followingis a specification.
This invention relates to time-indicating devices, and has for its object the arrangement and construction of a simple mechanism whereby a clock or timepiece is adapted to record on separate dials or faces provided with hands or other indicators the time or the sum of the times occupied by a certain operation or series of operations, the mechanism being so arranged as to enable any dial or face to be immediately connected with or disconnected from the clock or timepiece at the will of the operator.
This device is particularly applicable for such purposes as recording the time occupied by any piece of work, whether performed at one time or in several portions, or by recordingthe time a telephone is in use, a clerk is employed in his writing, a speaker is addressing an audience, or a chemist or other operator is engaged in a laboratory process or experiment.
To carry my invention into effect, I take any ordinary clock or timepiece and I attach to it externally a cog-Wheel or other gear connected with the minute or hour hand mechanism of such clock or timepiece. To the clock or timepiece I attach a frame or other supporting device adapted to support one or more dials or faces having time divisions. I provide each dial or face with a hand or hands or index driven by a cog-wheel, wheel, or other gearing attached thereto, and I adapt each dial with its accompanying hand or hands and gearing to slide or move upon the supporting-framework radially to or from the cog-wheel or other gear upon the clock, so as to engage with and be disengaged from the gearing of the clock at will.
In order that my invention may be the better understood, 1 willnow proceed to describe the same in relation to the drawings hereunto 5 5 annexed, reference being had to the letters marked thereon, like letters referring to like parts in the various figures.
Figure 1 is a front elevation of my timeindicating device. Fig. 2 is aback elevation of the same. Fig. 3 is a detail view of the sliding sleeve carrying the indicating-dial and gear-wheels. Fig. 4 is a sectional view of the same.
Referring to Figs. 1 and 2, it will be seen that the frame A, which may be of any suitable form, but is here shown cruciform, is attached to the back of the clock B, provided with the cog-wheel E, connected with the minute 01' hour hand mechanism, and that each dial 0 and its gearing K is mounted upon a sleeve D, adapted to slide radially to or from the cog-wheel E upon one of the radiating arms of the frame, so as to be capable of being moved relatively to the clock with great facility. It will be seen from Fig. 2
that the four upper dials are disengaged from and the two lower dials are engaged with the cog-wheel E of the clock B. I provide memorandum-tablets F upon the frame adjacent to the dials O 0, upon which any given fact can be recorded which may have reference to the particular dial adjacent to it. The sleeveD is provided with a spring-tongue having a projection G, which is adapted to engage into either one of the holes 11 in the arms of the frame, so as to maintain the wheels in or out of engagement, as circumstances require. A plurality of separate and independent operations can be timed by this arrangement.
Having now particularly described this invention, what I claim, and desire to secure by Letters Patent, is-- A time-indicating device consisting of a timing mechanism, in combination with a cruciform frame, a sleeve on each arm of said frame and adapted to slide thereon, a dial carried on said sleeve, an indicator for said dial, and gearing mounted on the sleeve for operating the indicator, whereby any set of gearing can be engaged with the timing mechanism by sliding its sleeve along the arm.
In witness whereof I have hereunto set my hand in presence of two witnesses.
