RECORDING TIME-LOCK.

Application filed May 26, 1916.

make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form apart of this specification.

My invention relates to registering timelocks of the type which makes a record of the time, or hour and fraction of an hour, when the lock is operated to lock or unlock the door to which it is attached so that an examination of the record will show'the time of opening and closing and the intervening period of time.

The present invention has for its object to reduce the number of parts or gears heretofore employed in operating the record carrying table, disk or plate and to insure greater time accuracy by lessening the friction incident-a1 to constructions heretofore employed and the loss or'difference in time 1 resulting therefrom; and to drive the rec- 0rd carrying plate or table by a practically direct connection between said plate or table and the spring drum of the operating clock mechanism as will be hereinafter made to appear; and also to further improve the construction.

To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the features hereinafter particularly described and then sought to be clearly defined by the claims, reference being had to the accompanying drawings forming part hereof, and in which:

Figure 1 is a front elevation of a regis-- Fig. 4 is a detail, looking at the front of the plate supporting the snail mechanism;

Fig. 5 is a plan view of Fig. 4;

Fig. 6 is a side view looking at the opposite side of the plate from Fig. l;

Fig. 7 is a section on the line 7-7 of Fig. 4;

Fig. 8 is a perspective of the lever which lifts the plate carrying the snail;

Fig. 9 is a perspective of the slidable plate which carries the snail and its operating P Fig. 10 is. a perspective of the stylus; and

Fig. 11 is a. face view of the record-receiving dial.

In the drawings the numeral 1 designates a portion of a door having attached thereto a lock-case 2 containing a bolt 2 actuated from the inside by a key applied to the lock 3 or from the outside by a key actuating the lock tumbler 4:Wl10S8 stem carries studs 5 engagin the rack 6. The case also contains the ever 7 actuated in the movement of the bolt for lifting the plate 8 guided by the platesS and 8 and normally pressed downward by spring 8, and which carries the pinions 9 and 10 and toothed wheel 11 and its snail 12 which cooperate with the marker or stylus 13 and its snail actuated arm 14, held to place by the spring 14" as heretofore in a well known construction of this type of lock, the casing also being provided with a hinged lower lid 15 and known form of locking members 16 and 17, and further provided with an upper hinged lid or cover 18 providedwith an approved type of lock 19, or one having a rotatable looking tongue 20 the details of which are not illustrated because not claimed herein.

. The parts thus generally referred to may be 4 a toothed wheel from which rotation was transmitted to the record table or plate, the pinion being carried by a shaft the inner end of which carried a pinion meshing with the toothed gear of the sprin driving drum of the clock mechanism. I the pinion at the outer end of the shaft mentioned was accurately adjusted good results in the accuracy of time was possible but if not so adjusted there was likely to be more or less loss of time recorded in the course of twentyfour hours, or in a longer or shorter period of time, and there was also considerable friction between the parts which it is desirable to overcome with the view of insuring 1 will be set mmewhat ofi' center, and the shaft or spindle 21 which will carry the recording dial table or disk 30 is set practically deac center and above the spring drum 23 of the clock mechanism and has a gear or toothed wheel 24 which meshes with the gear 25 of the spring drum so that the dial carrying table will be revolved directly from the 15 spring drum through the shaft 21. The toothed wheel 24 is' frictionallv held to. the shaft 21 by a collar 26 held fixedly to the shaft at one side of the gear and by a coiled spring 27 bearing at one end against a loose washer 28 hearing a ainst the wheel and at the end bearin against a collar 29 fixedly held to the shaft. This permits the shaft 21 to be turned against the friction exerted by the coiled spring when it is desired to adjust the table carrying the record-receiving dial in setting the dial for, the fame of day to which the record-receiving dial is set or adjusted for its work, the toothed wheel 24 at such time being held against rotation by reason of meshing with the toothed wheel 25 of the spring drum.

On the outer end of the spindle or shaft 21 is mounted the table or disk 30 which carries the record-receiving dial 31 and also the attached pinion 32, the table and the pimon being attached to the spindle so as to turn therewith by making a portion of the spindle angular in cross section as shown at 33, or otherwise, and prevented from movin lengthwise thereon by means of a beade screw 34 entering the endof the spindle and its head bearin against the end of a tubular extension or s eeve 35 projectin from the face of the table 30. he recordreceiving dial 31 is held to the table or disk 30 by studs 36 on the table projecting through corresponding openings 37 in the record-receiving dial and by spring fingers 38 carried by a thumb nut 39 screwed onto the threaded extension or sleeve 35. The pinion 32 of the table 30 meshes with the pinion 9 so as to rotate it and the connected pmion 10 for rotating the toothed snail.

wheel 11 with the teeth of which it meshes. From the foregoing it will be appreciated that the record carrying dial is carried by a spindle actuated through a single gear directly from the spring drum, and that said shaft is set practically dead center and above the spring drum, which results in reducing the number of gears for transmitting motion to the record carrying dial and also the friction incident to the parts dispensed with, and insures a more accurate time keeping. It also provides for the pinions through centrally which motion is transmitted to the snail carrying wheel having motion transmitted thereto directly from the shaft which carries and drives the record carrying dial as well as providing for an easier and simpler placingin position and removal of the record carrying dial and associated pinion through which movement is transmitted to the pinion that transmits movement to the snail carrying wheel.

' he record receiving dial is made as usual of a sensitized paper preferably divided radially into subdivisions of hours and fractions of hours for ready reading although such subdivisions are not absolutely essential. The stylus makes an arcuate trace on the record receiving dial during the period that the bolt is in its locked as well as unlocked positions preferably in one are for one position and inva different are for another position, and also radial traces in throwing the bolt from one position to another; as is the case in some registering locks of this type.

At the point where the stylus makes its mark on the record receivin dial there is provided a backing-plate 40 for the recordpaper which plate may be supported from the plate 41 to which other parts of the mechanism are attached. r

I have illustrated and described the preferred construction ofthe parts embodying the invention but changes can be made therein and essential features of the invention retained.
