WATGHMAINS CLOCK.

Specification of Letters Patent.

Patented Nov. 25, 1919.

Application filed November 13, 1916. Serial No. 130,960.

7 To all whom it may concern Be it known that I, FRANKLIN HARDINGE, a cltlzen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in WVatchmens Clocks,

watchmens clocks and has for its object the provision of a clock casing in which is contained clock. mechanism and a strip of material, preferably paper, driven by the clock mechanism, the device being so arranged as to recelve a strip of paper of sufliclent size tomake a record of the watchmans trips for a substantially long period of time such, for example, for the period of, say, seven days. It has been the practice in the past to pro vide a circular dial arranged to be rotated v once every twelve or once every twenty-four hours.

After the dial had made one com plete rotation it was necessary to renew the dial. It is one of the objects of the present invention to employ substantially the same mechanism as was employed in these prior art devices and to adapt such structure to receive instead of a circular dial a strip of material which is mounted upon two spools, one a supply spool and the other a take-up spool, thus enabling a single record receiving means to cover a substantially long period of time.

These and other objects of my invention will be more clearly pointed out in connection with the accompanying drawings, wherein, V

Figure 1 is a rear elevational view of the clock of my invention, showing its rear door opened to revealthe interior construction;

Fig. 2 is a cross-sectional view taken along the line 2- -2 of Fig. 1, looking in the direction indicated by the arrows;

Fig. 3 is a fragmentary cross sectional view of the means for producing a record whenever the door of the clock casing is opened, this view being taken along the line S-3 of Fig. 1, looking in the direction indicated by the arrows;

Fig. 4 is a detail perspective view of the take-up roll Fig. 5 is a view similar to Fig. 1, showing a modified arrangement for driving the take-up spool from the clock mechanism, and

Fig. 6 is a cross-sectional view taken along the line 66 of Fig. 5.

Similar characters of reference refer to similar parts throughout the several views.

Referring first to Fig. 1, 7 indicates the clock casing, preferably cylindrical in shape, having mounted therein the clockwork shown at 8. The front of the casing 7 not shown is provided with the usual clock dial and hands operated by the clockwork 8 to indicate the time. Hinged at 9 to the casing 7 is a door 10 circular in shape and arranged when inclosed to conceal all the mechanism shown in Fig. 1, which is disposed within the casing 7.

Preferably the upper end of the casing 7 is provided with an aperture 11 registering with a corresponding aperture or bore provided in the key guideway 12. This key guide is secured to the outer side of the easing 7 in any suitable manner. Secured to the inside of the casing 7 and positioned one on each side of the aperture 11 is a pair of guides 1313 extending, as most clearly shown in Fig. 2, from the front of the easing to the rear thereof. Slidably mounted within the guides 13 is a support 14: pro vided with two studs shown at 15 and 16, the purposes of the studs 15 and 16 being to rotatably support spools or to serve in themselves as spools for the record strip as will be subsequently described.

Mounted in alinement with the aperture contained in the casing 7 and in alinement with the bore contained in the guide 12, which aperture and bore permit the insertion of a key to the interior of the clock casing 7, is a second key guide 17 secured by means of the rivets 18 or in any other similar manner to the support 14. The guide 17 has provided in its lateral sides the slots shown at 19 and 20, the material forming the guideway being forced outwardly as shown at 21 and 22 to form a guide for the paper strip shown at 23.

The supply roll of the paper strip 23 is mounted on the stud 15, while the take-up roll thereof is mounted on the stud 16 as shown, the portion of the strip interposed between the supply roll and the take-up roll extending through theslots 19 and 20, so

that the strip of paper is fed through the center of the guide 17. By the insertion of a key into the guide 18 through the outer guide piece 12 a record may be made on the paper strip 23 at the point inalinement with the indicating piece shown at 24. The

particular class of key employed to make the record on the strip forms no part of the present invention and need not therefore be described.

The inner end of the take-up roll 25 has connected therewith a gear 26 meshing with a plate 27 havin the slots 28 cut therein, the material of t e plate 27 interposed between the several slots forming teeth meshing with the teeth of the pinion 26. The central portion of the disk 27 extends downwardly as shown in Fig. l and is provided with a triangular opening 29 arranged to receive a triangular piece 30 carried by the shaft 31. The shaft 31 has also secured to it a gear 32 meshing with the pinion 33,

the pinion in turn being driven in the usual manner from the clockwork shown at 8. In the particular construction shown in Fig. l the shaft 31 is arranged to make one complete revolution every twelve hours, though of course this may, if desired, be changed to suit the particular requirements. To hold the plate 27 onto the triangular piece 30 a cap 34 is provided which fits around the outer end of the shaft 31 to hold the disk in place. This cap, however, is made removable so that the disk 27 may be removed when this is desired.

To provide a slight friction on the supply roll so that the strip of paper may be held taut within the guide 17 the spring member 35 is provided which tends to rotate about its pivot 36 in a clockwise direction (Fig. 1).

The paper strip 23 preferably contains 7 lines to indicate the hour and minutes and in view of the fact that the take up roll 25 is driven at a constant rate of speed and that the CllClll'l'lfGlBllCG of the take-up roll becomes greateras more of the strip is re ceived, the graduations or lines provided on the strip may be arranged so that the lines indicating the minutes or hours are spaced a greater distance apart at the end of the strip than at the beginning thereof. Although I have illustrated the take up roll as bein driven at a constant rate of speed,

'I wish 1t to be understood that the roll may vide the mechanism shown in detail in Fig. 3. The support 14 contains two inwardly extending lugs 37 and 37 slidably supporting the U shaped member 38, having its inner end 39 extending through the lower guide piece 21, the upper end of the part 39 being sharpened so that when it is moved upwardly it will penetrate the record strip 23. The U member 38 carries the flange 40 between which and the lower lug 36 a compression spring 41 is interposed, the tendency of the spring 41 being to move the U member 38 upwardly to penetrate the record strip. When the door 10 is closed, however, as shown in Fig. 3, the member 38 is held in its depressed position and remains in such position as long as the door is closed. As soon as the door is opened the member 38 is released and the cutting part thereof 39 permitted to make an indication on the strip that the door has been opened.

When it becomes necessary to remove the record strip the cap 34 and then the disk 27 is removed. The guide 17 is then grasped by the fingers and pulled outwardly, carrying with it the su port 14 and the record strip. The old strip may then be removed and a new one placed upon the supply stud 15, one end of the strip being secured to the take-up roll.

Fig. 4 shows one form of take-up roll 25 which comprises a sleeve 42 having attached thereto the disk 43. The sleeve 42 is arranged to fit around the stud 16, so as to rotate thereon. The inner end of the sleeve 42 may be threaded as shown at 44 to receive thedisk 45 and gear 46, the disk and gear preferably forming a single part. If the gear 46 is secured to the sleeve 42 by means of threads it is desirable that the threads be cut left handed so that there will be no tendency to unscrew the gear from the sleeve when it is being driven by the disk 27.

In Figs. 5 and 6 I have illustrated a device wherein it is unnecessary to remove any of the transmission gearing extending between the clockwork and the record strip when renewal of the stri is necessar In this figure the clockwork 18 shown at 7 containing the pinion 48 meshing with the gear 49 mounted on the shaft 50. The ar 49 contains the slots 51 meshing with t e gear 52 journaled at 53 to a downwardly extending support 54 carried by the cover 55 e11 tending over the gear 49. The gear 52 meshes with the inion 56 having its spindle 57 extending t irough the sup ort 54 and secured to a second pinion 58. e pinion 58 meshes in turn with the gear 59 ournaled.

inner end the gear 67 meshing with the gear 59.

It will thus be seen that in the device shown in Figs. 5 and 6 the support 63 together with the paper strip may be removed from the clock casing without in any way removing any of the intermediate gearing extending between the clockwork and the strip. The support 63 may be removed by simply pulling it outwardly from within the casing. When the support 63 is again replaced the gears 67 and 59 are brought into mesh and a connection again made between the clockwork and the record strip.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

A watchmans clock comprising a casing having a key opening, a pair of guides secured to the inner side of said casing in spaced parallel relation, a support slidably mounted in said guides, a supply spool rotatably mounted adjacent one end of said support, a takeup spool rotatably mounted adjacent the other end of said support, a key guide secured to said support in register with said key opening and having a slot formed in the opposite sides thereof to provide a pair of guides for receiving a record strip and means for rotating said takeup spool.

In witness whereof I hereunto subscribe my name this 3rd day of November, A. D.
