To all whom it may concern.-

Be it known that I, EM'ERY M. HAMILTON, of New York, in the county of New York, and in State of New York, have invented certain new and useful Improvements in Apparatus for Recording Measurements of Time, Space, or Quantity; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of my device as arranged for use. Fig. 2'is a plan view of the upper side of the base, the inking-ribbon being broken away and the platens removed to show the printing-dies. Fig. 3 is a perspective view of a portion of the timetrain and the die-operating connections separated from the other parts of the device. Fig. 4 is a vertical section of the device upon a line passing through the axes of the dial and printing-dies. Figs. 5 and 6 are cross-sections of the platens upon lines a: a: and y y, respectively, of Fig. 4. Fig. 7 is a plan view of a ticket which has been stamped at .the commencement of an interval of time, and Fig. 8 is a like view of the same when stamped at the close of such interval.

Letters of like name and kind refer to like parts in each of the figures.

The object of my invention is to enable the value of intervals of time at any predetermined rate to be computed and recorded by automatically-chan gin g mechanism; andto this end my said invention consists in a device constructed and adapted for use in the manner and for the purpose substantially as hereinafter specified. I

In the carrying of my invention into practice I employ a rectangular metal base-plate A, which is secured upon a wooden block B, that corresponds therewith in general shape, and within its upper side is provided with a recess 1) for the reception of some of the operative mechanism.

TVithin the front portion of the base plate A, at its transverse center, is formed a circucular opening a, that is glazed at its upper side and receives and contains the dial 0 and hands 0 and c of a time mechanism, the train D for which is arranged beneath in the reeess I).

In rear of the dial-opening a, and in a line with the same, there is formed in the baseplate A a circular recess a, that generally has a depth about equal to one-half the thickness 5 5 of the latter and at its center a extends entirely through said plate. TVithin said recess is placed a die E, which has its upper face substantially flush with the face of said baseplate, and upon the same is provided with a concentric series of raised numerals e, that are placed at equidistant points around the circle, and by tens extend progressively from 0 to 90, the arrangement being such as to divide said circle into one hundred equal parts, of which each successive tenth division is numbered. Said die is provided with a hub e, that extends through the opening a and engages with the hub f of a wheel F, which wheel is connected with the time-train D, so as to have an entire revolution during any predetermined period of time.

Within the line of numerals e of the die E, and in juxtaposition with the zero-numeral 0, is a raised arrow-head e and inside of the 7 5 latter is formed a circular recess 6 that receives and contains a second die G. Said die G is provided with a central hub g, that ex tends downward through an axial opening in the hub e and engages with an arbor h, which is secured within a toothed wheel H, and the latter is so connected with the timetrain as to cause said die Gto make one complete revolution while said die E is revolving ten times. Upon the upper face of said die G is a concentric series of raised numerals g and g,which are equidistant from each other, are ten in number, and extend in consecutive order from 1 to 0. At apoint opposite to and outside of the character 0 a raised arrow-head g is formed upon said die.

Secured to the end of the base A, adjacent to the dies E and G, is a bracket-arm I,which from thence extends upward and thence horizontally inward, and at a point directly over 5 said dies carries a cylindrical sleeve or barrel K, that is arranged with its axis in a line with the axes of the latter.

WVithin the barrel K is loosely fitted a hollow sleeve L, which extends from the upper end downward below the lower end of the same, and upon its lower projecting end has secured or formed a head Z, that has such diameter and thickness as to enable it when moved downward upon the dies E and G to cover the space between the series of numerals e and g and to impinge upon the arrowheads 6 and g Said sleeve is adapted to be moved downward by means of a rod Z, that is secured horizontally within its upper part and extends outward through a verticallyelongated slot i in the barrel I, and is provided upon its outer end with a knob Ziwhile it is returned to its upper normal position, when released, by means of a spiral spring M, which extends between said rod Z and a screw i, that passes horizontally through the lower end of said barrel and into averticallyelongated slot Z in said sleeve.

Fitted loosely within the sleeve L is a second sleeve N, which upon its upper projecting end has secured a knob 02, and upon its lower end a, which normally is flush with the head 1, has secured an annular head or enlargement 72?, that is provided with connecting-lugs 15, which project radially inward through corresponding vertically-elongated slots Z and Z in said sleeve L. The lower end n of said inner sleeve N has such diameter and thickness that when pressed down upon the die G it will cover the annular series of numerals g, while the enlargement n has such dimensions as to cause it to simultaneously cover the series of numerals e of the die E. The inner sleeve N is normally held with a yielding pressure at the upper limit of its motion by means of a spiral spring 0, which has less strength than the springM, and is placed between the knob 12. and the operating-rod Z of the sleeve L.

An inked ribbon P, having its ends wound around suitable spools beneath the base-plate A, and from thence passing upward through slots a and a in said base-plate and across dies E and G, and a guide-strip Q, secured upon and extending across said base-plate at one side of the dial and die-recesses, completes the device, the operation of which, in connection with the time and pay of an operative, is as follows, viz: The numerals upon the die E represent cents, and those upon the die G represent dollars, and said die E is arranged to make one entire revolution in the time required for earning one dollar at thepredetermined rate, which time, for the purpose of illustration, is fixed at five hours, or twenty cents per hour. Suppose that at 8 a. m. an operative reports for work. A ticket R, bearing his name and the date, is placed in position over the dies and each of the stamping-heads or platens is pressed downward until the ticket has impressed upon its lower face, through the medium of the inked ribbon, a facsimile of the numerals of each die with the arrow-heads of each pointing to zero, as shown in Fig. 7. At 4.30 p. in. the operative quits work and presents his ticket for stamping, when said ticket is placed in the precise position it before occupied and the central platen moved downward, so as to cause the arrow-heads alone to be impressed thereon; but as in the meantime the dies have been steadily revolving their change of position since 8 a. in. will cause the last impression of the outer arrow-head to come opposite to the number of the cents-die and the impression of the inner arrow-head to occupy a position between the numbers 1 and 2 of the dollars-die, as seen in Fig. 8, so that said ticket would show that the operative had earned and was entitled to one dollar and seventy cents for the eight and one-half hours of his work.

It will be obvious that the values reprew sented by the figures or characters of the dies and the relative or separate rates at which they revolve may be varied at will without departing from the spirit of my invention.

Having thus described my invention, what I claim is A machine for measuring and recording intervals of time in which are combined two rotatable concentrically-arranged printingdies, each of which carries an annular series of numerals-type, and a pointer-type that is in juxtaposition with the zero-type of the series, said pointer-types being arranged, respectively, one within the line of its annular series of numerals-type an d the other outside of the line of its annular series of types, a time-train that is adapted to rotate the dies at uniform but relatively dilferent velocities, a platen that is adapted to press a ticket simultaneously upon the numerals-type of both series, and an independently-operative second platen that is adapted to press said ticket simultaneously upon the pointer-type of both dies, substantially as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this 14th day of February, 1887.

EMERY M. HAMILTON.
