PRINTING-RIBBON SHIFTER FOR WQRKMEN TIME-CLOCKS.

' Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed January 2. 1906. Serial No. 294,051.

Y skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements applicable to workmen time-clocks, such clocks being em loyed to record the time upon which woriimen enter their employment and leave said employment for the day. The invention relates specifically to means I for shifting a two-colored printing-ribbon so that workmens time-cards may have printed thereon in appropriate color the time of entering and the time of departing each day. For example, regular workmen may have the time of beginning and leaving the works or factory each day printed upon their cards in one color-for example, blue-while irregu lar workmen may have the time printed upon their cards in different colorfor example,

red-so .that each class of workmen may be readily distinguished by the color in which the time is printed upon, their respective cards.

Preceding a detail description of the invention reference is made to the accompanying drawings, of which Figure 1 is a-front elevation of the lower ortion of a workmans timerecording clock aving our improvements applied thereto.

Fig. 2 is a side elevation. Fig. 3 is a detail elevation of the card chute or holder and the printing devices. 1 Y

In a detail description of the invention similar reference characters indicate correspondin parts. r

The c ock mechanism is omitted from the drawings, for the reason that it is not in-- have each a upon the cards the various times are illustrated in the drawings.

Proceeding immediately to a description of the features involved in the present improvements, A designates a crank which is instrumental in shifting the ribbon-carriage vertically in order to present the tw0colored portions of the ribbon in printing positions relative to the time-printing wheel. This ribbon-shifting crank 1s connected to a rockshaft B, suitably mounted in the frame, and extending from which shaft are arms C C, bifurcated at their outer ends. The outer. ends of these arms are loosely connected in grooves to the upper ends of sleeves D, upon which ribbon-spools D are mounted. The sleeves, D rest u on stationary bars J. The upright shafts andG are surrounded at their lower portions by springs E, having their ends inclosed,by collars E, the lower collars being fixed to said shafts, while the upper collars slide thereon and are pressed against the upper bars J. These springs thus act to prevent the ribbon-spools from unwinding too freely by exerting a constant pressure upon the spools through the upper collars E and the bar J; The shafts G and G are firmly supported in upper and lower bars J. The printing ribbon is divided equally throughout its length in two diflerent or contrasting color portions I and I- For example, one half of said ribbon throughout its length is colored red and the other half blue. The lower ends of the shafts G and G ear-wheel Q, by -means of which the said shafts are alternately turned in opposite directions to wind and rewind the printing ribbon from one spool to the other. These rewinding movements are imparted alternately from one shaft to the other through gears P on shaft P, one of such gears P engaging its respective gear Q alternately.

P is a shifting sleeve, to which is fixed one of the gears P andto which is also fixed a ratchet P. The latter ear is operated from the impression-leverl, which carries upon it an arm S, which engages the ratchet P The lever T o crates the impressionarmM to press the tic e'ts S and the printingribbon against the type-Wheel N, the latter wheel printin the time on, each ticket corre sponding' to t e time appearing-en the face of the clock. (SeeFig. 3.) The impressionarm M is actuated from the lever T through laqprojection C, which extends from the shaft iipon-which said impression-arm M is mounted, Aspring M is connected to this arm and' to a stationary part of the framework, so that the tension of the spring M tends normally to throw the impressionlever M inwardly toward the type-wheel.

Pivoted to the lever T is a trip-lever T ,whichhas a shoulder T engaging the trip projection C when; the lever T is lowered wer leasing said trip projection C, and permitting the im ression arm or lever to make contact with the tickets or cards of the workmen in order to produce'the desired time impres-- sion thereon. v

O designates the several partsof the shifting device by means of which the direction of fulcrii'med at O jected between the Y O and the upper ends-of both ofsaid' levers the travel of the printing-ribbon is reversed at the'limit of each feed of the'ribbon. One of these elements consists of a lever which is and has its lower end progearwheels P and P.

The other one of said levers is fulcrumed at are connected by a cross-link, the whole constituting a shifting frame, the upperends of which lie in proximity to the outer-face of the printing-ribbon. U on the printing-ribbon there are two suita le projections U (one 'only of which appears) and which extend out sufficiently from he face of the ribbon to engag'e'alternately the upper ends of the levers O, and when-engagmg said levers from opposite sides the shaft P is thrown in opposite directions by the lower end of one of said vers engagin either the wheel P or the ing connections are made between the shaft P 'and the gear-wheels P on the upright shafts G and G. The wheel 13', through w tab the shaft '1? is driven, is always in en- 7 ga%ement with the driving-lever S. v 1 is the card holder or receiver, into which each workman deposits. hisca and takes the necessary impression upon entering and leaving each day.

K is an arm projecting upwardly from the rock-shaft-B and carrying on-its upper end the pointer which points to the difi'erentportions of the sight-indicator K, which is sta-' This sight-indicator is divided into two contrasting colors L and L, corresponding to the two colors I. andiI of the printingribbon. When the rock-shaft Bis operated tionary.

, from the crank A to shift the printing-ribbon to present the desired color in line with the inting -wheel, the arm K, with the pointer is likewise shifted to indicate the color upon the indicator K". In the present instance the upper half of the indicator K is red to correspond with the lower half I of the he result is that alternate dri vinking-ribbon, which is shown Fig. 1 to be in a position to print that color upon awork- 65 man s time-card.

The card-holder B is movable along its supporting-shafts B to positions for the incoming and outgoing workmen, as shown on the indicator B to indicate v In and Out by a pointer B.

This shifting of the card holder or receiver is obtained through the shifting-lever B which has a connection'B with the card-receiver.

While we have described certain parts of 7-5 the well-known features of a workmans time-clock, we do not desire to claim such portions, for the reason that theycomprise no part of our invention, our invention relating solely to the means for shifting a two-colored 8o ribbon to print the time in d'iflerent colors upon workmens time-cards and to themeans for indicating to the eye the color after each shifting operation of the ribbon. The clock mechanism has been purposely omitted; but 8 5 it will be understood that the type-wheel N, from which the time is printed, is rotated from a clock. This is done throu h a shaft W, which is operated from the 0100 mechanism and imparts movement to the time-print- .gc

ing wheel N through gears (See Fig. 3.) Having described our invention, we claim- 1. A printing-ribbon shifter, com rising u right shafts, ribbon-spools carrie upon s eeves mounted upon the upper endsof said 9 5 a rockshaft, two arms extending from and in the plane. of said rockshaft and engaging the upper ends of said sleeves, a crank through which the rock-shaftupright shafts,

is given movement, an'indicator-arm eXtend- 100 ing from the rock-shaft, and an indicator denoting the positions of the printing-ribbon when the rockhaft is actuated to elevate or lower said ribbon. I

2. A printing-ribbon shifter, comprising'1o5 tions.
