(Cl. ZIM-'36) 5 Claims.

This invention relates to a time recording mechanism, more particularly for recording the time of arrival of carrier pigeons at their home station when freed from a distant point; accordingly, the mechanism adapts itself for use in pigeon racing contests. The mechanism is contained in a box into which the indicating bands on the legs of the pigeons are deposited in the order of the arrival of the pigeons at their home station, the mechanism being operated upon the deposit of each band, so that by means of a time stamp (which is incorporated in the mechanism) operating on a movable paper web, the pigeon arrivals are successively recorded. In such contests, each pigeon owner is provided with a box containing the timing mechanism and a committee or other designated authority inspects the mechanisms to see that they are in suitable lcondition and ready for operation, sets the clocks and closes the boxes, each having provisions to prevent or detect its re-opening until the box is returned to the committee. The pigeon owners then refV turn to their home stations, following which his pigeons are released o'r freed by the committee. As each pigeon arrives at its home station, the indicating band on its leg is removed and placed in a cavityprovided in the mechanismand the latter operated by the owner, to record the arrival. At a predetermined time, each box is opened by the committee and the bands in the respective cavities noted with respect to the successive time stamp impressions on the paper web, and comparisons made with similar impressions in the other boxes to determine the Winning y pigeons. k

One object of the invention is to provide an improved mechanism of this character having signal means, operable automatically, to indicate to the operatorr or pigeon owner predetermined `positions of the mechanism to prevent inaccurate for confused recordings on the paper web.

lmaterially simplified to insure accurate `operation and ready assembly.

Another object of the invention is-to provide -an improved mechanism of this character'wherein the operating parts are co-operatively related to prevent fraudulent recordings.

A further object of the invention is to provide an improved mechanism of this character wherein provision is made to suspend a section of inking material for the time stamp.

Otherfobjects of the invention will be apparent to those skilled in the art to which my invention relates fromk the following description taken in connection with the accompanying drawings,

'In the drawings, I indicates a suitable casing enclosing the mechanism hereinafter set forth. The casing consists of a main section la and a hinged section Ib to permit access to the mechanism. These parts may be locked closed in any desired manner. The main and hinged sections of the casing are preferably of requal size in height, which facilitates access to parts of the mechanism and removal and replacement of windows 2, 2a, each of which fits recesses 3 formed in the adjacent side walls of the sections la, Ib I(see Fig. 3). The `window 2 is arranged in front rofthe dial or face of a clock, indicated as an entirety vat 4 and suitably secured withinthe casing l, being preferably secured to a base lx removably mounted on the bottom wall of the casing section la. The base Ix is supported in spaced relation to the` bottom wall to accommodate certain parts which are later referred to. The clock is provided rwith suitable stamping elements (see Fig. `7) operated byv theA clock and arranged to record the hour, minute and second each time the mechanism vis operated (as later set forth), on a paper web 5. The paper web 5 is mounted on supports 6, 6', and fed from one to the other toA receive successivetime stamped records or impressions. The clock and stamping elements and lthe operating connections therebetween may be of any desired construction for which reason they are not illustrated and described in detail. The supports 6, 6', for the paper web 5 may be of any desired construction and both automatically actuated by operating parts of the mechanism, but in the preferred arrangement, as herein disclosed, only one support for the paper web is driven in the manner later set forth. The support 6 for the paper web 5 consists of an upright spindle 6a having a lower collar 6b and an upper collar 6c. The spindle 6a is suitably mounted on the base I. The collar 6c is removably secured to the upper end of the spindle 6a, whereby a roll of paper web 5 may be readily mounted on the spindle as shown in Fig. 5. As shown in Fig. 4, the collar 6c is formed with an internally screw threaded opening which threads on the upper, reduced end of the spindle against the resulting shoulder. 'I indicates as an entirety a frame comprising spaced uprights 1a, 1b, suitably secured to the base Ir and a plate 'Ic suitably secured to flanges provided on the upper ends of the up. rights "Ia, 1b. 6a: indicates a leaf spring anchored at one end on the upright Ia and normally biased against the roll of paper web 5 to frictionally retard it from unwinding. The paper web 5 is guided around a pair of spaced posts 8, 8a, from the support 6 to the support 6', the latter being driven a predetermined distance during each operation of the mechanism. The posts 8, 8a, are suitably mounted at their lower ends in the base Ix and are spaced at opposite sides of and forward of a movable platen 9, when the latter is in normal position, so as to yguide the web between the platen 9 and the stamping elements. I indicates a section or sheet of transfer material disposed between the stamping elements and that portion of the paper web guided by the posts 8, 8a, in front of the platen 9. The transfer material may consist of carbon paper or woven material inked similar to typewriter ribbons. The end portions of the transfer section III are removably secured between clamping ele-l ments I I which are spacedly mounted at or adjacent-the opposite sides of the clock 4 and support the transfer section I0 in a transverse plane between the timestamp elements and the paper web 5. To provide the clamping elements II, I provide rearwardly of the clock a thin sheet of metal IIa, which is secured to the base I :r and formed with an opening to expose the stamp elements. Along the opposite ends of the sheet IIa I provide angles IIa. One side portion of each angle is suitably secured to the sheet I Ia; whereas its other side portion forms a clamping wall IIb between which and a strip IIc the transfer The platen 9 is provided on its face or front side with a pad or layer of relatively soft material 9. On its rear side, the platen 9 is provided with a hollow boss 9" threaded internally to provide a screw thread connection with the outer end of a hollow reciprocatable member I4. The outer end portion of the member I4 extends through and slidably ts an opening 1', in the upright 1a whereas its inner end portion telescopes over and is slidably supported by a guide member I5, which is mounted on the upright Ib and extends .inwardly therefrom. Within the reciprocatable `member I5 and between the platen 9 and inner section is removably clamped. Each strip I Ic exvthe wall IIb, and hence yieldingly presses the strip II c toward the wall IIb to detachably secure the transfer section thereto. As shown, the walls I Ib are disposed at right angles to the plane in which the transfer section is supported, so

that relatively little spring tension on the strips IIC is required to support the transfer section I0; and this light spring tension permits each strip to be readily deflected either to insert a section of transfer material or take up on slack therein. A Y

end of the guide member I5 I provide a relatively strong coiled expansion spring I6 arranged to be put under tension when the platen 9 is retracted (toward the right as viewed in Figs. 4 and 5) so that when the platen 9 is released, the spring I6 will impel the platen toward the stamp elements and effect an impression therefrom onto theY paper web 5. At its inner end, thereciprocatable member I4 is provided with a collar I1 with which a cam I8 ,engages to retract the member I4 and then disengages it to release the member I4 for operation by the spring I6. Ila is a relatively light coiled spring surrounding the member I4 and interposed between the wall 1a and collar I`I for moving the member rearwardly following each operation of the platen. As will be observed, in the movement of the platen 9 under the influence of the spring I6, the spring I4a is compressed between the collar I'I, and wall 1a, the tension thus storedvup in the spring I4a being utilized to move the platen rearwardly out of engagement with the paper web 5, so that the latter is free to be moved or fed forwardly by the operation of the support 6', as later set forth. At one side the collar I'I is formed with a through opening IIa, in parallel relation to the axis of the member I4. A rod I9, which is supported on and extends inwardly from the upright "Ib, extends through the opening I'Ia and through its engagement with the walls thereof it prevents rotative movement of the member I4 and maintains the collar I'I in a predetermined relation to the cam I8. The collar II may be secured to the member I4 in any desired manner, but preferably it is split, as shown in Fig. 9, and the Asplit portions clamped to the walls of the member I4 by ascrew IIb. The cam I8 is suitably fxed to a shaft 20 (which is later referred to) lrotatably mounted in and extending through the base Ifr and top wall 1c, its upper end being shaped for engagement by a crank (not shown) and related to an opening 20a formed in the top wall of the casing section Il), whereby the shank ofthe crank may be applied to the shaft 20 to rotate it.

2 I indicates a stud shaft extending upwardly `from the top wall 1c. The shaft ZI has fixed to it a collar 2 Ia, having a reduced lower end fitting an opening in the wall 1c, the shaft extending through the opening and an opening in the flange on the upper end of the upright lo, so that by means of a nut 2Ib threaded on the lower end of the shaft, the walls 1a and Ic are secured tof'gether and the shaft 2I rigidly secured in posi- `holders preferably consist of cups depending from` the disk 23, their open endsv being flush with the top surface ofthe disk. The circumference of the disk 23 is divided intov twelve equal imaginary sections, corresponding to the step-by-step operation of the disk in one revolution thereof. Ten of these sections areprovidedwith cups 24 numberedl to I0, consecutively, one section is blank and designated S (to indicatey the starting or setting position of thev mechanism) and the remaining section is blank andy designated F (to indicate the end of the recordings). AsI shown', the section marked S is in advance of the cup numbered I and the section marked F is rearward of the cup numbered and adjaecent to and'in advance of the section marked S. Cups 24 are disposed below the blanks S and F for a purpose later apparent. Also, as shown, the cups and blanks are equal distances from the axis of the disk, so that each moves into registry with an opening formed in the top wall of the casing section Ib, which opening permits the indieating devices removed from the pigeons, upon arrival thereof at their home station, to be de# posited in the cups 24. In this arrangement, provision is made to record the successive arrival ofr` one to ten pigeons. The driving connections between the shaft-2|) and disk 23 are constructed to (a) operate the latter one step (counter-clockwise as viewed in Fig. 2) eachtime the cam |6 retracts the platen 9 and releases it to make a time record or impression, which operation takes place in one complete rotation of the shaft 20, and .(b) pre` vent reverse rotation of the disk (clockwise) or disconnection of the disk from the driving ele-H ments carried by they shaft 2B and rotated in either direction, 'so thatfraudulent operations and time records cannot be effected.

The driving connections comprise .the following: 26 indicates a plurality o'f slots formed in the marginal portion of t-he disk 23 `and extend-v ing inwardly from its periphery. Due to the fact that in the starting position of the disk the blank S is in registry with vthe opening 25, aslot 26 is provided adjacentA to and in advance of thev cups 24 numbered 3 to ISL, respectively, blanks F and S and cup numbered I, but omitted from the margin adjacent to the cup numbered 2, where by the disk periphery forms a. stop, as later set forth, to prevent continued operations'` of the mechanism..

Each of the slots 26 is adapted to receive a pin 21 extending upwardly from a collar A28 disposed in a plane below the disk 23 and having a depending hub 28a suitably fixed to the shaft 20,.A` so as to vbe rotated thereby, the engagement of thev pin 21 with the end andfront walls of the slot, during one rotationl of the collar, serving to move thedisk 23 one step to bring the adjacent rearward'cup or blank (as rthe case may be) into registry with the openingl 25 andfthe adjacent rearward slot 26 into position to receive the pin 21 for the succeeding rotative movement of the collar 28. As shown, the marginal portion of the collar 28 extends beyond the marginal portion of the disk 23 in the path of movement of the cups Zland'henc'e prevents rotative movement of the disk independently of! the shaft' 20 vor during the movement of collar whenV the pin 21 is disengaged from the walls of each slot; but to permit rotation of thev disk 23 by theengagementof thev pin 21 with the walls of each slot 28, the marginal portion of the collar 28 is formed with afrecess 28h, which accommodates the cup L24Y 'adjacent-that slot 26- into and out of whichthe pin v21 moves' eachl operation. The pin 21 preferably extends upwardly to a point closeto the inner surface of the top wall of the casing section Ib, so as to prevent ylifting 'of the disk. 23 (while the casing I is closed) far enough to disengage the pin and per mit fraudulent operation of the disk. 29 indicates al separate shaft mounted in th wall 1c and base la: and extending through the latter to lprovide a driving connectionwith the shaft 20, as later set forth. The shaft 29-extends through and slidably nts the hubs on the. upper and lower ends of the support 6', to sup-- port the latter thereon and permit movement of; the support endwise of the shaft. The-upper end portion of the shaft 29,` below the wall 1c, is provided with a laterally extending lug or pin 30 adapted to removably seat in a recess 3| formed in the hub on the, upper end of the support- S.; The lower end of the support or spool vl. rests on a lever 32-which is suitably pivoted at its inner end on a standard 313 and normally biased up-V. wardly by a spring 34 coiled around the shaft 29. As shown in Fig. 10 the hub 35 at the lower end of the support or spool 6 is provided at its lower end withr a flange and the lever 32, kwhich is formed with an opening through .which the hub extends, is arranged between the lower eri-d wall ofv the support 6 and the` flange provided on the lower end of the hub 35. Invk this arrangement-the spring is interposed between a collar 36k which is fixed to the shaft29 and rests on the base Im, and the hub 35 and normallyY acts lthrough the latter to maintain the lever 32 and. support .6^ elevated, withthe pin 30 seated in the recess 3|, whereby rotation of the shaft 29 drives the support 6'.. The lever 32 through its engagement with the flange on therhub 35, when pushed downwardly y(see dotted linesin Fig. 10), serves to move orslide. the support 6 downwardly endwise of the kshaft y29, such movement effecting a disengagement kofr the recess 3| fromthe pin 30, whereby the support 6' is free to rotate in either direction, so that the paper web 5 wound thereon may be readily removed. The side wall of the support or spool 6.', intermediate its ends, is provided with a resilient lclip 31, under which the outer or free end portion of the lpaperweb 5 is positioned to secured it to the support ready to be wound thereon. When the recording operations are completed and ithe casing is opened, the support 6 is releasedordetached from the shaft 29' and the `support rotated manually to windy thereon the portion carrying time stamp impressions to feed the ycontiguous unstamped portion into position to be secured to the support 6'.. `That portion of the web, carrying the impressions is then severed from the unstamped por-y tion, yand unwound from the support, following which the resulting free end portion of the web is secured to the support 6. y318 indicates as an entiretythe connections between the shaft 20vand the shaft 29, arranged to lock the latter against movement through a predetermined rotatve movement of the shaft 20 in each revolution thereof and to rotate the yshaft 29'during" they remainingv rotative movement of the `shaft zu,A In this operation, the Shaft 2s is held against! rotation while the platen is op`i erated by the' cam I8 `and released, so that at the time an lmpr'esison" is made yon the paper the latteris at rest, 'but'following the impression yon the web,` the shaft 29 is rotated to wind the succeeding portion of the web 5 on the support 6l' to feed the contiguous portion thereof intopositionto receive a timestamp impression.

By preference the connections between the shaft 20 and the shaft 29, when operating to rotate the latter and the support 8', Wind on the support a portion of the web long enough to move that portion thereof on which the last impression was made by theY time stamp devices, into view behind the window 2a, whereby the impression may be checked with the hands of the clock 4; The connections 38 comprise the following: 39 indicates a disk suitably fixed to the shaft 20 below the base Im and provided on its lower face with a locking element 40 and a series of depending pins 4|. The locking element 40 consists of a thickened portion of the disk 39 having an arcuate outer wall 40a struck on a predetermined radius of the shaft 20. The series of pins 4I extend from one side of the locking element 40 around the disk 39 to the opposite side thereof in uniform spaced relation so as to successively move into and recede from uniformly spaced slots 42 respectively, formed in a disk 43, which is secured to the shaft 29 below the base Ix. The slots 42 in the disk 43 extend radially inwardly from its periphery and are uniformly spaced to successively receive the pins 4|, the engagement of each pin with the wall of a slot serving to rotate the disk 43. As shown in Fig. 6, one side edge of the disk 43 between two of the adjoining slots 42 is of concave shape from end to end, as shown at 42a, having a curvature concentric to the wall 40a of the locking element 4U, and arranged to mesh therewith, as the disks 39 and 43 rotate. Fig. 6 shows the position of the disks 39 and 43 at starting position (see Fig. 2 where pin 21 is in position to enter the adjacent slot 26). If now the shaft 20 is rota-ted one revolution, which, as already set forth, rotates the disk 23 one step and reciprocates the platen 9 to make an impression on the paper web, the Wall 40a will lock the disk 43 against rotation (their complementary relation permitting the locking element 49 to move relative to the wall 42a While coacting with the latter to lock the disk 43 against rotation), until the wall 40a clears the wall 42a, following which the pins 4l will successively engage the walls of the slots 42 to rotate the disk and thus eifect rotation of the support 6 to wind a portion of the web 5 thereon. In this connection, it will be noted that in the assembly of the disks 39 and 43 on their respective shafts, they are predeterminedly related so as to revolve the walls 40a and 42a into interlocking relation in each revolution of the shaft 20 in co-ordinated relation with the operation of the cam I8 so as to lock the disk 43 in advance of and during the operation of the platen tov effect a time stamp impression, whereby the latter is made while the paper web is at rest.

44 indicates a signaling device for indicating the position of the shaft 2U when it has made one complete revolution to effect an operation of the platen 9 and movement'of the disk 23 one step and is ready to start a succeeding operation, the purpose being to prevent over-feed or underfeed of the paper web 5, whereby each time record thereon will be spaced from adjoining records rather than be overlapped and confused. AS shown in Fig. 2, the shaft 2o is lin starting position; that is, the pin 21 is in position to engage the adjacent slot 26 and the signalling device 44 is visible through the window 2a. If the shaft 20 is rotated to effect an operation, as already set forth, the signalling device, which is operatively connected to a movable part of the mechanism, will recede from view and re-appear as the pin 21 reaches its starting position, thus indicating to the operator that the shaft 20 has made one complete revolution and is again in starting position.

'I'he signalling device 44 consists of a flag supported on a movable member 45, which is preferably slidably mounted on the bottom wall of the casing section la. The slidable member is provided with an elongated slot 45a, which forms a guide way engaged 4by a plurality of spaced screws -46 supported in the bottom wall of the casing section la. A coiled expansion spring 41 suitably anchored at one end and connected at its opposite end to the movable member 45 normally tends to move the latter in one direction against a stop 41a to position the flag 44 at one side of the window 2a. The movable member 45 is provided with a striker 48 normally arranged in the path of movement of a pin 49 depending from the disk 43, and positioned thereon so as to engage the striker 48 to operate the movable member 45 in the opposite direction as the shaft 20 approaches the end of its movement in making one complete revolution. Accordingly, as the shaft 20 completes its movement, the movable member 45 is moved by the pin 49 in opposition to the spring 41 to position the ag 44 behind the window 2a to signal the operator. As already set forth, the shaft 20 is shown in its starting position; accordingly, in the succeeding operation of the shaft 20, the pin 49 will ride the striker 48 following which the movable member 45 will move toward the left (as viewed in Fig. 6) under the influence of the spring 41 against the stop 41a with the striker 48 in position to be engaged by the pin 49, as it revolves with the disk 43, and moved back to the position shown in Fig. 6.

50 indicates a ratchet wheel fixed to the shaft 29 and engaged by a spring operated pawl 5I, which is pivotally mounted on the lower side of the plate 1c, to prevent movement of the shaft 20 counter-clockwise (as viewed in Figs. 2, 6 and 8).

52 indicates as an entirety a detection means for indicating on the paper web each movement of the cover section lb to open or closed position. Of these means, 52a indicates a recess formed in the post 8a. 53 indicates a pin disposed on the opposite side of the paper web 5 and arranged to be projected into the recess 52a, each such operation of the pin serving to punch a hole in the web. The pin 53 is mounted on a lever 54 (see Fig. 7), which is pivotally mounted on a shaft 55, the latter being supported by the side walls of a U-shaped member 56 suitably fixed to the base Ix (see Fig. 3). The lever 54 is normally biased outwardly against a stop 54 by a suitable spring 54a, which is fixed to the bottom wall of the member 56, to position the pin 53 outwardly of the paper vweb 5. The upper end portion of the lever 54 is provided with cam walls 51, 51a, reversely inclined relative to its outer face, and arranged to be engaged by a lug or projection 5I fixed to the inner face of the adjacent wall of the casing section Ib. As shown in Fig. '7, the lug 53 is disposed below the cam wall 51 so that if the casing section Ib is opened, the lug in riding the cam wall will swing the lever 54 inwardly, the effect of which is to project the pin 53 through the paper web 5 into the recess 52a. Obviously, when the casing section I b is closed, the engagement of the lug 58 with the cam wall 51a will punch a separate hole in the paper web. Accordingly, a record is made on the paper web each time the casing is opened and closed. The

punched holes serve the purpose of indicating the setting of the mechanism and closing of the casing by a committee in advance of time stamp records being made on the paper web and the opening of the casing by or in the presence of the committee when the records are completed. As the detection means automatically operate each time the casing is opened and each time it is closed, the committee is able to determine whether or not casing has been opened without the proper authority.

Operation-In a racing contest the casing I is submitted to the committee and set in position for operation, as shown in Fig. l with space S in registry with the opening 25. The shaft may then be operated by the committee or the owner of the casing to make a time stamp impression, corresponding to space S, and to move holder No. I into registry with the opening 25. Thereafter, at the home station, upon arrival of each pigeon, the band is removed from the latter and deposited in that holder which is in registry with the opening and the shaft 20 rotated one revolution following each deposit. If ten pigeons have been entered in the race, the shaft 20 is operated again corresponding to space F which rotates the disk 23 to a point where the holder No. 2 is opposite the pin 21, but as a slot 26 is omitted from the disk in advance of this holder 2, any attempt to again operate the disk and platen will be blocked by engagement of the pin 21 with the side wall of the disk 23. If less than ten pigeons have been entered in the race or less than ten return to the'home station, the number of the holder in registry with the opening 25 will indicate how many pigeons did return, so that the committee can determine how many times the mechanism was operated and identify the time stamp impressions on the web 5 therewith.
