making part of this specification.

Our invention relates to the use, in combination with a time-movementafan oscillating lever, a continuously-Involving device,

and an adjustable mechanism, the several parts being so constructed and relatively arranged, as more fully hereinafter .explained, that the rotary motion primarily produced by the time mechanism will be converted into an oscillating motion, recurring periodically at intervals, of greater or less extent, according to the adjustment that for the time being may have been given to the parts made capable of adjustment for such purpose.

This mechanism will be found useful in many connections, where it may be desired to convert rotary motion into oscillatingora backward-and-forward motion, or where it may be desired to check and to permit motion of any kind at regularly-recurring intervals.

- The invention is fully illustrated in the accompanying drawings, in which- Fignre 1 represents the movement, in perspective, as applied to operate the rotating b 001: is constructed with a concentric slot, g, and is or valve of a gas-cock, to check an permit alternately the full flow of gas. Fig. 2 is a front elevation of the same. Fig. 3 is a side elevation. Fig. 4 is a sectional view of the parts mounted on the main spindle or arher of the time a movement, and specially designed to showthe position of the fric- 'tional washer t Figs.- 5 and 6 are two sectional views, showing how the movementmay be usedto produce an oscillating motion in a rotating block or obstruction-piece, as in the valve of a gas-cock. Figs. 7 and 8 are plan views, respectively, of the two disks or wheels B and D, which, when superimposed, make up the compound cam-wheel B D, shown in Figs.

1. and '2. a g A represents any suitable support to which .the time mechanism and its conuectcdparts may be attached. On this support is a clock or similar mechanism,0, that maybe driven by the expansion of a coiled or other spring. This mechanism, being of a common and wellknown construction, and shown in the drawings, need not be elaborately described. The sleeve on the spindle (I, however, which in an ordinary clock is the one on which the hourhand is placed, and there makes one revolution in twelve hours, in our construction is so geared as to make but one revolution In twen- I ty-fourbours. ()n this sleeve there is mounted, so as to turn with it, a circular dial-plate or time-table, B, which has upon it hour-marks c, or marks representing divisions of an hour;

and upon the perimeter of this time-table wheel there is a cznmprojection, (I, designed for operating an oscillating lever, for a pun pose hereinafter described.

This cam-projection can be varied within desired limits by the following means; Over the sleeve of spindle a, but so that it may be turned independently of such sleeve when desired, there is placed a second plate or wheel, D, a portion oft-he perimeter of which is cut away, as at f f, the diameter of the remaining portion being the same as that of the camprojection on the wheel B. This second plate provided with a setscrew, i, which passes through this slot and takes into the plate B, thereby enabling the two wheels to be clamped to each other in any desired relation that the extent of the slot 9 will permit, so that they will revolve together under the action of the clock-work or other driving gear or mcchanism, and thus for the time be practically combincd into one compound wheel. This capacity for relative adjustment possessed by the two wheels enables the connnon cam-pro jection to [3 e enlarged or diminished at pleasare, the common depression in the porimeters being at the same time correspondingly diminished or increased. i

Pivoted i=7 worlgingrelation to the com; pound whee; 3D is the bent lever h,on'e arm of which, m, rides upon the perimeter ot the wheel, which thus cons 'tl'ltgfor such leverarm a moving support' 'hc cam portion of which raises and sustains the lever,- while the depressed part permits it to return to its for; mer position, a spring, I,-being used to produec this last action. The other arm, j, of this lever moves synchronously;with the arm m, and thusacquires an automatic periodical oscillat-ing motion, depcndcntupon 'the' time mechanism, and repeated once in each twentyfour hours, the relative times of the two. sue ecssivc phases of any ouci com'plctc movement of, th'e'lever depending upon. the adjustment of the cam projection upon the wheel revolved bythc ispindle'a.
