To all whom it may concern:

Beitknown that we, ANSON N. PALMERand W'ILLIAM W. KIMBALL, both of Syracuse, in the county of Onondaga, in the State of New York, haveinvented new and'useful Improvements in Time-Recorders, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description. I

to This invention relates to improvements in Workmens time-recorders, and refers more particularly to the printing mechanism for recording upon a suitable record-sheet the time of arrival and departure of the workmen. In this class of devices the record-sheet is provided with a colu mu of employee-designating characters,usually the numerals l, 2, 3, 650., and with a series of parallel blank spaces having the usual headings In and and Out, the time of arrival of each employee being printed after his particular number in the columns designated by the headings In or Out. This printing mechanism is similar tothat set forth in our pending application, Serial No. 75,023, filed September 11, 1901, in which a rotary type-wheel is mounted to move axially across the face of the platen.

The object of the present invention is to move this type-wheel axially by automatic means, such as the clock mechanism which is employed to rotate the type-wheel.

Another object is to provide means for centering and holding the printing-type at the 3 5 printing-point to prevent its vibration during the operation of printing.

Referring to the drawings, Figuresl, 2, and 3 are respectively a side elevation and top and inverted plan views of the printing 4o mechanism, embodying the various features of our invention. Fig. 4 is a detail view of the automatic means for shifting the position of the type-wheel axially. Fig. 5 is a face View of the time-printing wheels and the centering and holding device shown in its normal or inoperative position. Fig. 6 is a similar face view of a fragmentary portion of the type-wheel and the centering and holding device in its operative position. plan of the mechanism seen in Fig. 6.

Fig. 7 is a top Fig.

8 is a perspective View of a fragmentary portion of the type-wheel, showing the laterally projecting stops or pins. Fig. 9 is a perspective view of the holding-pawls,one of the pawls being broken away.

Similar reference characters indicate corresponding parts in all the views.

A ti inc-printing wheel 1 is feathered upon a clock-rotated spindle 2 to move transversely of a suitable platen 3, and is provided with a series of laterally-projecting stops or pins 4, which are adapted to be engaged by centering-pawls 5 and 6 to hold the type-wheel from rotary movement or vibration during the operation of printing upon the record-sheet secured to the platen. The spindle 2is connected by a universal coupling 7 to a clock mechanism 8, whereby rotary motion is imparted to the spindle and also tothe type- I Wheel 1. One section of this spindle is mounted upon one end of a forked rock-arm 9,which is fulcrumed intermediate its ends at 10, the other end of the arm being connected to a reciprocally-movable bar 11, by which the forked arm is rocked for moving the spindle and the type-wheel carried thereby toward and from the platen 3 in the operation of printing upon the record-sheet. This rock arm 9 is mounted upon fixed upright standards 12, which rise from a supporting-frame 13,and serves to hold the forked arm from endwise movement with reference to the axis of the type-wheel.

The type-wheel 1 is usually formed with a laterally-projecting hub or sleeve 15, upon which is loosely mounted a depending arm 16, carrying a second type-wheel 17 of much smaller diameter than the type-wheel 1, but

type-wheel l and adapted to engage successively at each revolution one of a series of pins 19, projecting laterally from the typewheel 17, so that at each revolution of the type-wheel 1 corresponding to one hour of time the type-wheel 17 is moved one typespace.

The mechanism thus far described is simi lar to that set forth in our pending application above referred to, and this description is believed to clearly disclose the construction and manner of operation.

The frame 13 is provided with transverse ways 22, arranged parallel with the axis of the type-wheel 1, and upon which is mounted a sliding support 23, carrying an upwardlyprojecting arm 24, which is engaged with the hub 15 of the type-wheel 1 in such manner as to move the type-wheel back and forth along the spindle as the support is operated along the ways 22. The means for reciprocating this support along the ways consists of a rock-arm 25, which is fulcrumed at and its free end is connected by a link 26 to the lower face of the sliding support 23, the arm 24 being adapted to rock horizontally and is provided with a circularrack 27, which meshes with a similar rack 28, formed upon a lever 29, this lever being fulcrumed intermediate its ends at 30 to a fixed support 31, which forms a part of the frame 13.

, A spring 32 is secured to the fulcrumof the rock-arm 25, and one end is engaged with a lug 33 upon said arm in such manner that the spring operates to move the sliding support 23 in one direction, and therefore transmits motion through the medium of the toothed racks 27 and 28 to the lever 29. This lever is provided with a stud 37, which is held against the face of a rotary cam 38, said cam being rotated by the clock mechanism 8 through the medium of rotary shafts 34 and 35 and intermeshing gears 36, one of the shafts, 35, being connected by gears 39 to the hour-hand-driving spindle of the clock mechanism. A portion of the cam-face 38 is arranged to permit a gradual movement of the type-wheels across the face of the platen and may be either a continuous incline or a stepby-step arrangement, as seen in the drawings, another portion of the cam-face being arranged to operate the levers 29 and 25 against the action of the spring 32 to return the sliding support 23 and type-wheels to their normal starting positions, the rotation of the cam being so timed as to move the typewheels from their starting position across the face of the platen and back again once in twenty-four hours, although it is apparent that the period of time for effecting this movement may be changed without departing from the spirit of this invention. The

purpose of shifting these type-wheels transversely of the platen, asjust described, is to permit a series of impressions to be made at regular or irregular periods of time after each employeedesi gn atin g character upon the record-sheet to indicate the time of arrival and departure of the employees under the headings In and Out.

The essential feature of novelty in the mechanism thus far described consists in the automatic shifting of the type-wheels transversely of the platen as controlled by the clock-actuated cam 38 and spring 32, it being evident that, if desired, this spring 32 may be dispensed with, and the movement of the levers 24 and 29 may be controlled entirely by the cam 38.

Mounted upon the sliding support 23 is the pawl 5, which is fulcrumed intermediate its ends at 43, its inner end being provided with a hook-shaped shoulder 44, adapted to interlock with one of the stops4 of the type-wheel 1 when said inner end is rocked downwardly to the position seen in Fig. 6.

Pivotally mounted upon the pawl 5, between the fulcrum 43 and shoulder '44, is a second pawl 6, which is also adapted to engage one of the stops 4 as the pawl 5 is depressed to slightly shift the type-wheel and prevent the shoulder 44 from striking the points of the stops when the pawls descend. The engaging faces of these pawls 5 and 6 are arranged to engage opposite faces of adjacent stops, the pawl 6 being first to engage one of the stops and move the type-wheel so that the shoulder 44 readily enters between two adjacent stops, and by the continued downward movement of these pawls the engaging end of the loose pawl approaches the shoulder 44, and thereby impinges the stops between the engaging faces of the pawls and firmly holds the type-wheel from vibratory rotary movement.

We preferably employ the same means for operating the pawl 5 and rock-arm 9 as that set forth in our pending application above referred to, and have therefore shown only a portion of such operating mechanism, consisting of a rotary cam 45, which is actuated by a rack and pinion 46, the periphery of the cam engaging a stud or roller 47 upon an arm 48, and an eccentric-pin 49, secured to the rotary member 45,-and rides in a bifurcated end of the rod 11, so that as the-member is rotated the rods 11 and 48 are simultaneously elevated, the elevation of the rod 11 operating to force the type-wheel to its printing position, and the elevation of the rod 48 simultaneously rocks the pawls 5 and 6 into engagement with the stops 4.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
