UNITED STATES PATENT OFFICE THEODORE C. mm OF CHICAGO, ILLINOIS, ASSIGNOB TO AUTOMATIC ELECTRIC INC,

OF CHICAGO, ILLINOIS, A CORPORATION 01' DELAWARE Tm! HOOD-DIN G DEVICE Application fled August 18, 1937. Serial No. 814,088.

My invention relates in general to recording devices, and more particularly to those devices from which a record may be obtained in permanent record form.

The main feature of m invention is the provision of a time recording clock which is accurate and reliable in its performance, which will clearly print a very complete record and which may easily be adapted to a great variety of uses.

This feature, as well as others not particularly mentioned, will be more fully hereinafter described in the following description.

For a more complete and better understanding of my invention, reference may be had to the accompanying drawings in which:-

Fig. 1 is a perspective View of the time recording clock with enough of the casing cut away to show these features which constitute a part of my invention.

Fig.9 is a perspective view of the stamping and recording mechanism which also constitutes a part of my invention and which is, in this particular case, designed for use with the clock shown in Fig. 1.

Fig. 3 is a rear view of the stamping and recording mechanism with a portion of the rear mounting plate cut away so that the construction of the mechanism may be more readily seen.

In these figures, like parts are denoted by like reference characters.

The clock in Fig. 1 may be any suitable one which is arranged for recordin the time and date. In this particular case I ave used a standard recording clock manufactured by the Follett Time Recording Company, of Newark, New Jersey. This clock consists of a regular spring drivenfclock mechanism adapted to operate indicating wheels which, when placed'in correct stain ing position, will indicate the time and ate. To this standard recording clock I have added new features, or elements, to work simultaneously with the mechanism of the standard clock to give certain other indications.

. To this clock, I have also added the mechanism shown in Figs. 2 and 3, which consists of electrically operated means for stam ing and recording the indications of the c ock in a permanent record form.

Before proceeding with a detailed description and operation of the time recording clock with the added features or elements, it might be well to state that the complete recording mechanism assembly may be put to innumerable uses, especially in supervisory systems and in remote control systems. One

typical use to which the product of my invention may be put is that shown and described in the application of Harry E. ggrzshey, Serial N 0. 214,060, filed August 19, Mr. Hershey has provided means whereby my invention may be used to supervise the operations of a plurality of switching devices such as circuit breakers or the like. In roviding these means, he has employed a se ecting mechanism which operates in response to the operation of any one of the switching devices, to select that device and connect itto the recorder so that a record may be made of the operation. The recorder is arranged to operate in synchronism with the selecting mechanism as is explained in Mr. Hersheys application and which will be explained herein a little further on in the description.

Referring now to Fig. 1 more in detail, it will be seen that the complete clock has a casing consisting of a base, 1, and side walls, 2. The front wall is in the form of a door hinged to the base and adapted to swing forward and downward. On base 1 is mounted the clock mechanism M, which has, besides the regular spring movement, indicating Wheels 3, 4, 5, 6 and 7 which are controlled by the regular clock mechanism and indicate the month, day of. the month, the hour the minute of the hour, and the portion of the day, AM or PM, respectively. The face of the clock is visible through a round opening in the front side of the casing and is protected by a glass crystal.

As the clock works so far described are not a part of my invention, it is thought that a further description of them is unnecessary. To the mechanism as before described I have added the indicating disc 8 and the indicating plate 9, both of which are rotatably' mounted on the shaft 10. Firmly attached to the disc 8 and concentric with it, is a ratchet wheel 11 which is for the purpose of rotating disc 8. The periphery of disc 8 is marke with numerals 1-25, inclusive, and the ratchet wheel 11 has 25 teeth. I have also added the rela 12 whose armature 13 has a long projecting arm with a pawl 14 hinged at 15, the hinging portion consisting of two pro ect ing ears on the end of the pawl 14. A 0011 spring about the hinge-pin 15 is adapted to hold the pawl 14 in engagement with the teeth of ratchet wheel 11. The stroke of armature 13 is so adjusted that with each deenergization of relay 12, the disc 8 is rotated one step in a clockwise direction about the shaft 10. The relay 12 is mounted on the middle supporting plate 16. Indicating plate 9 is of t e general shape shown in F ig. 1 and it has a projecting arm 17 formed integral with it and on the direct opposite side of the shaft 10. In the plate 9 is a slot 18, the sides of which are arcs of circles concentric with the center of rotation of plate 9. A pin 19 is mounted in the front supporting plate 16 and is so located as to fit in the slot 18. This pin 19 acts as both a forward and backward stop to the movement of plate 9. To operate the plate 9, I have added the relay 20 with its armature 21 pivoted at 22. A connecting rod 23 joins the projecting arm 17 to the armature 21 at pivot points 24 and 25. A tension spring 26 keeps the armature 21 in its inoperative position, that shown in the drawlngs, when relay 20 is deenergized. When relay 20 is energized it attracts its armature 21. The motion of armature 21 is transmitted to arm 17 and plate 9 through the connecting rod 23, thus rotating 9 and 17 in a counterclockwise direction about shaft 10.

On the periphery of plate 9, there is raised marking X which is so located that it is in alignment with the indications on indicating discs 3,4, 5, 6, 7 and 8 in the stamping position when the armature 21 is in its operated position.

As I said previously, the recorder is operated in synchronism with the selecting mechanism of Mr. Hersheys invention. This is accomplished by operating relay 12 simultaneously with the motor magnet of the selecting mechanism which may be a well known forward-hunting, rotary-type switch. Thus it can be understood that when relay 12 and the motor magnet are operated together, the indicating disc controlled by relay 12 and the wipers controlled by the motor magnet will be moving together. The numerals on the periphery of indicating disc 8 are so positioned that when the wipers of the selecting mechanism are advanced to the first set of bank contacts, the numeral 1 will be in the stamping position. Numeral 2 will appear in the stamping position when the wipers have been stepped to the second sets of bank contacts, and so on accordin to the number of sets of bank contacts to w ich the wipers have access. The switching devices are connected to the bank contacts of the selecting mechanism in an orderly fashion so that device #1 is connected to the first set of contacts, device #2 to the second set of contacts, and so on. Thus the numeral on the indicating disc will denote the number of the device so ected by the selecting mechanism.

Relay 20 is so connected that when the switching device is in one position it will energize and when the device is in another position it will not energize. Thus the presence or absence of the mark X will denote the position of the switching device. Thus a complete record from the recorder will indicate the time and date of the operation of the switching device the number of the device operating, and the position to which it has moved.

The stamping and recording mechanism shown in Figs. 2 and 3 is mounted on the top plates 27 which acts as the cover of the clock casing. On the underside of this top plate are mounted 2 rollers 28 and 29 between which is stretched an inked tape. When the top plate is in position this inked tape will 3e stretched across the tops of the indicating 1scs.

In the center of the plate 27 is mounted a bracket 30 which is adapted to support the solenoid coil mounting frame 31 and solenoid coil 57. Through the hollow core of solenoid coil 31 extends the octagonal plunger 32. An octagonal plunger is used so that the rubbing surface will be reduced to a minimum. On the lower end of the plunger is fastened a stamping block which is not visible in the drawings. This stamping block is rectangular in shape and is long enough to cover all of the indicating discs and plates. There is a rectangular hole in the top plate 27 throu h which the stamping block passes when tire plunger is operated. Around the extending portion of plunger 32 is a spiral restoring sprin 33 which is held in place between the top 0 coil 31 and the large, flat-headed screw 34 screwed into the top end of plunger 32.

Close and parallel to the rear edge of top plate 27, there is mounted a vertical mounting plate 35. On this plate 35 are mounted two large spools 36 and 37 by means of large bolts not visible in the drawings. These spools carry the paper upon which is stamped the indications of the clock mechanism. The paper unrolls from spool 36, passes under guide bars, not visible, over the hole in top plate 27 and under stamping block on end of plunger 32, and is wound onto spool 37.

To operate the spools, I have attached to the rear side of spool 37, a ratchet wheel 38 and provided the H shaped member 39 which is centrally pivoted on pivot pin 40 which is fastened in mounting plate 35. The guide engage the teeth of ratchet wheel 38.

pins 41 and 42 are fastened near the ends of the opposite sides of the member 39. Pin 41 rides on the head of screw 34. The ur ose of pin 42 will be described hereinatter. About the pivot pin 40 is wound a spring 43 so that when plunger 32 is down member 39 will be rotated in a counter-clockwise direction as far as the plunger will allow it to rotate. ward under the pressure of spring 33, 39 will be rotated in the opposite direction against the tension of spring 43. Pivoted .on the axle of spool 37 is pawl bearing member 44 which has the. two radial arms 45 and 46 located directly opposite each other, and the radial arm 47 located at an angle of 90 degrees to arms 45 and 46 but lying in the same plane. Pawl 48 is centrally pivoted, with respect to itself and arm 45, at 50. One end of pawl 48 is bent towards the center of rotation of the pawl bearing member 44 so 213120 e pawl is held inengagement by spring 52. Pawl 49 is similar to pawl 48, being pivoted at 51 and being held into engagement with teeth of ratchet wheel 38 by spring 56. Pawls 48 and 49 are so arranged that'when one is in engagement, the other will be Just half-way between two. teeth of the ratchet wheel. These pawls alternate in engaging the teeth. Thus a more uniform amount of rotation of spool 37 may be secured. The connecting rod 53, pivotally fastened to 39 at 54 on the opposite side of the pivot pin 40 from the pins 41 and 42, and to arm 47, at 55, translates the motion of 39 to pawl-bearing member 44 and thus to arms 45 and 46. Thus it will be seen, that when plunger 32 is pulled down, 39 will rotate in a counterclockwise direction looking at Fig. 2, imparting a rotary movement to 44 in a clockwise direction and when plunger 32 returns to normal it presses against pin 41 and rotates 39 in a clockwise direction. 39 turning in this direction will impart an opposite motion to 44, 45, and 46, which through the action of either one of the pawls 48 or 49, will rotate spool 37 in a counter-clockwise direction. This rotation of spool 37 will wind paper upon itself and unroll it from spool 36. Holding springs 58 and 59 are fastened to the mounting plate 35 and enga e the teeth of ratchet wheel 38 to prevent bac ward rotation of spool 37.

It can readily be understood that for one complete stroke of plun er 32, the length of the paper which woul pass the stam ing block would vary according to the size 0 the roll on spool 37 When the roll of paper on spool 37 is very small, a turn of that spool governed by the stroke of plunger 32 will draw very little of the paper past the stamping block, and one record stamped on the paper is liable to be stamped almost directly on top of the previously stamped record.

Thus when the plunger returns up- Therefore, to overcome this objection I have provided means which will insure that the same length of paper will pass the stamping block after each stamping so that all stampings on the roll will be evenly spaced.

This means, or paper controlling mechanism, consists of a rocker arm arrangement to control the movement of an adjustable stop for the member 39. The rocker consists of the two rocker arms 60 which are rotatably mounted-on opposite sides of the bracket 30 by pivot pins 61. The opposite ends of the roc er arms 60 are connected together by a rod 62 on whichis a roller 63. The rocker arms are so spaced as to fit in between the two sides of the spool 37 and they are so placed and shaped as to allow the roller 63 to roll upon the roll of paper on spool 37. A tension spring, not shown, holds the roller 63 against the surface of the paper on spool 37. A triangular shaped member 64 is pivoted at its apex on in the end 0 bracket30. The pivot pin 65 is located so as to lie in the same vertical plane in which the pins 41 and 42 lie. The side of the triangular shaped member, opposite the apex, is an eccentric, the purpose of which wil be explained a little later. Trr

pivot pin 65 which is mounted a angular shaped member 64 is connected to rocker arms 60 by means of connecting rod 66 at pivot points 67 and 68.

The explanation to follow will be directed entirely to Fig. 3 so that directions of rotation will not be mistaken for those in the previous explanation.

As previously stated, the roller 63 rides upon the roll of paper on spool 37 It can be readily understood that as the size of the roll of paper on spool 37 increases, the rocker arms 60 will be rotated in a clockwise direction about pivot pins 61. This rotation of arms 60 will impart a clockwise direction of rotation to triangular shaped member 64 about pivot 65, which motion is translated by connecting rod 66. The position of 64 when the roll of paper on spool 37 is small is represented by the dotted-line triangle.

The manner in which this mechanism controls the amount of paper to be wound on spool 37, or to be drawn past the stamping block, will now be explained.

The pin 42 mounted on member 39, stops against the eccentric side. of the triangular shaped member 64 when the plunger 32 has moved downward. Thus it can be seen that the amount of rotation of 39 is controlled by member 64, the amount of rotation decreas ing as 64 is rotated in a clockwise direction. The eccentric side of 64 is so shaped that in controlling the amount of rotation of member 39, it allows only the same amount of paper to be wound upon spool 37 upon each operation of the stamping mechanism since, as previously explained, the rotation of member 39 is imparted to spool 37 by means of the pawls and connecting members. When the eccentrio is nearest to 39, the allowable rotation of 39 is at a minimum, but that rotation is suflicient to allow pawls 48 and 49 to be advanced a step, or one. full tooth.

As there are modifications and ada tions which can be made by one skilled in t e art without departing from the scope of the invention, it is not my invention to limit my invention to the present disclosure.

Having thus described my invention, what I consider new and desire to have protected by Letters Patent will be pointed out in the ap ended claims.

hat is claimed is:

1. In a recording device, having a recording tape and printing means, an auxiliary plate, carrying a printing character, associated with the device and having only two positions for bringing said character into and out of printing relation with the tape, a magnet for controlling said plate, an armature for the magnet, and lever means linking the armature and the plate, said lever means operating to bring the character into printing relation with the tape only when the magnet is energized.

2. In a recording device having a recording tape and printing means, a rotatable auxiliary plate carrying a printing character and associated with the device, an electro-magnet having an armature, and connecting means linking said armature with said auxiliary plate, said magnet operating said armature and connecting means when energized to rotate said plate in one direction to place said character in printing relation with said tape and when deenergized to rotate said plate in the reverse direction to withdraw said character from said printin relation.

In witness whereof, hereunto subscribe my name this 16th da ofAugust, A. D. 1927.
