NEW YORK, A CORPORATION TIME RECORDER Application filed March 2, 1925.

The present invention relates to improvements in time recorders andV is directed to general improvements in that class ot recorders known as card recorders. The recorder of the present invention includes timing mechanism and spring motor driving mechanism assembled within a bor; frame; and recording mechanism comprising type wheels7 card receiver dial unit and time train therefor, and a program wheel assembly, all mounted on a frame which is detachably secured to the main box frame.

Among the objects ot the invention is to provide certain novel assembly features of a time recorder whereby the clock mechanism is split up with the time controlling mechanism to the rear and at the upper part of the unit and the power drive disposed at the close proximity to the operating lever. This assembly has the purpose in view of obtaining compactness, ease of adjustment and inspection, gain in operation eiiiciency, and smartness in appearance.

Another object is to assemble the recorder parts themselves within a compact volume on a frame which is supported in front of the clock mechanism and is readily removable as a complete unit for the purpose of assembling or adjusting the clock mechanism. Over the entire framework there is placed a removable cover which likewise may be connected to the main supporting box frame and preferably locked to the recorder supporting frame. lVith this arrangement oi parts it is possible for a user to remove the cover of the recorder leaving all of the operating parts in position for inspection or minor repairs. It

extensive repairs or replacements are required in the recorder mechanism it is possible, after the coverv has been removed, to remove the framework of the recorder as a unit, thus removing all of the operating parts of the recorder which are carried thereby. If desired7 substitutions of new complete recorder units can thus bereadily made. Vith the recorder thus removed the clock parts, such as the pendulum, etc., are accessible for inspection. or adjustment.

Another Objectis the provision of sub- Serial No. 12,488.

assembly units for the entire time recorder whereby these various sub-assembly units may be built up separately and then assembled into proper cooperation with each other. According to the present invention there is a recording unit comprising several separate assemblies, a clock unit, and a power unit all separately contained and removable.

Another object resides in the provision of suitable means by which a workman will introduce an increment of stored power in the spring motor upon every operation of the recorder lever until the spring motor is wound to a predetermined limit, at which limit the recorder lever will automatically become iiicilective for fur-ther rewinding. Then the spring power falls below another limit, rewinding by the recorder lever is again rendered possible.

Another object is the provision of a very accurate minute jumping mechanism which is capable of being easily and precisely adjusted and having the purpose of automatically driving the clock hands and recording mechanism at the elapse ot one minute, or for automatically driving the same mechanisms at the end of any interval during which they might have been held from displacement, and for the equivalent length of the interval held up, without there being any interruption of operation of the clock.

Another object resides in the provision of a time jumping mechanism intermediate the spring motor drive and type wheels which will not cause an additional drag upon the spring motor or disturbance of the time controlling mechanism when the type wheels are held from rotation for an indefinite period of time.

Other objects involving novel constructions and con'ibinations of parts will appear in the specification and in the claims thereof setting Yforth a preferred embodiment of my invention which will be fully understood from the detailed description and drawings, in which:

Fig. l is a view of the interior of the time recorder looking from the right; Fig. 1A is a detail of the friction connection of the rewind actuating pawl on line lAlA of Fig. 1.

- )osition shown in Fig. 1.

In this posit-ion, ratchet wheel 18 will be actuated on every depression of operating lever 19, and gear will be advanced in the direction of the arrow to wind the spring motor. As the spring motor is gradually rcwound, gear 10 will rotate nut 44 counterclockwise and cause it to travel to the left yon the nearly non-rotating screw 45. Nut 44 will contact stud 42 and carry slide 34 to the left, as shown in Fig. 10, to the position where pawl 49 will be displaced to its maximum extent and then -suddenly snap the slide to the left, as seen in Fig. 11. This snap action causes pawl 26 to be suddenly disengaged fr'om contact with ratchet wheel 18 and thus throw out the step-by-step automatic rewind of the operating lever 19.

The disengagement is obtained through the lowering lof the rear end of Wishbone member when stud 39 is cammed downwardly thus causing member 25 to be positioned in its non-functioning position as described above. Set screws 51 are provided to adjust the timing relation between the snap action and ratchet positioning.

Power from the spring motor is distributed to the clock and recorder mechanisms by means of gear 1l and through the intervention of pinion 52 and gear 58, both fixed to shaft 54 (Fig. l). Gear 53 meshes directly with pinion 55 on shaft 56 which also carries beveled gear 57 fixed thereto. Beveled gear 57 meshes witn another beveled gear 58 on the lower end of short shaft 59. This short shaft is mounted in a bracket 60 fastened to the left hand plate 7 and carries at its upper end a` universal socket 61 for the reception of lthe lower end of a universal shaft This connection is readily severed as is also the .connection between lever 22 and link 23 in order that the entire spring' motor mechanism can be removed as a unit. Y

Sha-ft V62 is driven in a clockwise direction as seen from above, and its upper end 1o-,tates ashort shaft 63 to which is pinned gear 64 supported by bracket 65. Gear 64 drives gear 66 (Fig. 4) secured to shaft 67, which is supported at its rear end by the base plate 68 of the clock frame. The front end of the shaft is supported by a sleeve 69 which in turn has a fixed bushing 70 as a bearing. This bushing is tightly swaged in place in a hole in the front plate 71 of the clock mechanism.

The two plates 68, 71 are held rigidly together by four screws 72 and spacing sleeves 7 9 forming the frame of the clock mechanism (Figs. 8 and 4) which is separatively removable.

Loosely mounted on shaft 67 are two sleeves 69, 75, having respectively gears 7 6 and 77, comprising the two actuated gears of a differential. Pinned to shaft 67 is a spider 78 which has loosely mounted thereon a traveling bevel gear 79 through which motion is communicated from the` shaft to beveled gears 76 and 77 'ith which it meshes.

There is rigidly fastened to sleeve a. gear wheel 80 meshing with a small gear 81 comprising a part of the train or" gears leading from a Graham dead-beat escapeinent mechanism of the usual construction. The arbors of this escapement mechanism are journaled in plates 68 and 82 which arc held together by four bolts 83 and their spacing sleeves. 84 is the verge spindle to which is fastened one end of verge wire 85, while the other end is fastened to pendulum 86.

Mounted on sleeve 75 is a cam bearing sleeve 87 which is held from relative movement with sleeve 75 and made to rotate therewith by reason of the frictional force exerted by sp 1ing washer 88 bearing against gear wheel 80. The flexibility f this connection is for the purpose of adjusting the exact moment of advance of the program wheel, type wheel and time indicating mechanism, as will later be explained.

On sleeve 69 there is secured by a set screw 89 a `iumpinf.; member 90 which carries stud shaft 91 and gears 92v and 96 loosely journaled thereon. Gear 93 meshes with idler gear 94 which in turn engages pinion 95 fixed to one end of shaft 96. Th's shaftl is mounted in a. bearing 97 on umping member 99 and has a linger 98 pinned to the other end. This linger bears against the concentric surface 99 .of cam 100 until the surface is removed from beneath it, at which event the pawl wil rotate counterclockwise seen in Fig. 9, and land upon the surface, F 9, as will be later described. 191 is a. mass of material integral with jumping member and has the purpose of counterhalancing member 90 to insure uniform rotation.

There is fixed to stationary bushing 70 a large gear 192 which forms the tracl over which pinion 92- travels.

The purpose of this train of mechanism is to produce follow-up actuations of the clock and recorder mechanisms at periodic intervals, and it operates in the following manner: Between the instantaneous advancements of the driven mechanisms, jumping mem 3er 9() is held stationary as is likewise ybeveled gear 76 of the differential. Spider 78 is being continuously driven by the spring eab intermediate the said Leonesa ing lugs 134 engage clips 135 secured to frame 2. A lock 136 is provided preferably in the cover for the purpose of insuring freedom from meddling and for ailixing the responsibility oi' the maintenance and proper working' condition of the time recorder on some particular individual.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects previously stated, it is to be understood that it is not intended to conline the invention to the one form of embodiment herein disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
