`
` and along one side of the top of the box d, so
`
`To all whom tt may concern:
`Be it known that I, CHARLES AXEL DE
`CHAPERAUROUGH, doctor of medicine, a sub-
`ject of the Emperor of Germany, residing at
`Rotherbaumchaussee 63,Hamburg,in the Hm-
`pire of Germany, have invented certain new
`and useful Improvements in Time-Measuring
`Apparatus for Race-Courses, of which the fol-
`lowing is a full, clear, and exact description.
`This invention relates to a time-measure
`apparatus which is especially suitable for
`horse-races, and is designed to obtain an ex-
`act check regarding the runningof the horses.
`Apparatus as used for this purpose at pres-
`ent, generally in the form of a stop-watch,
`has the disad vantage even when adoublestop-
`hand is provided that the person measuring
`the time during a race is compelled to glance
`from the watch to the course, and vice versa,
`which is of course a double source of error.
`This disadvantage is avoided in my inven-
`tion by the automatic registering of the time
`without taking the eye off the course, thus
`obviating the overlooking or inaccurate ob-
`servation of the distance-posts.
`In orderthat this invention may be the bet-
`ter understood, I now proceed to describe how
`it may be carried into effect, reference being
`had to the accompanying drawings, and to the |
`letters marked thereon, like letters referring |
`to like parts in the various figures.
`Figure 1 is a sectional front view. Fig. 2
`isa plan, and Fig. 3 is a sectional side view
`on the line « # of Fig. 1.
`The construction of the apparatus is very
`simple and the various parts are arranged in
`a box @, which may be provided with a lock.
`A disk } is pivoted in the center of the box
`and is rotated by a clockwork c. Onthedisk
`b are provided ‘raised numbers, which run
`from ‘*1” to 60” in theapparatus illustrated.
`(See Fig. 2.) The rotation of the disk 6 is
`regulated so that the number advancesin one
`second a distance which is exactly the same
`as the distance between the numbers. A
`bridge d, arranged in the box a, carries a
`spring ¢, situated across the disk 6 and which
`is genorally in tension. The spring ¢ is held
`up by a recess in an angularlever f andis:
`guided byabarg. Astrip of paper h, wound
`on a roller 2, passes up on oneside of the box

`
`that the center of the strip passes over the
`numbersof the disk 0, which are situated or
`pass near the middle of the front of the box.
`The strip 2 is held in moderate tension by a
`weight.
`Thenumbersof the disk b indicate and reg-
`ister the time which a horse or other object.
`has run in the following manner: The whole
`course as seen by the observeris divided into
`equal distances and distance-posts are pro-
`vided to indicate such distances. When the
`horse starts, the person measuring the time,
`and convenientlysituated at a raised point,
`presses on an india-rubberball & of the appa-
`ratus. The compressed air passes from atube
`ik’ into an expansible casing or chamberJ,
`which is expanded downward bythe air, and
`thus presses the lower limb of the lever / also
`downward by means of a rod ™, so that the
`recess in the upperlimb of the lever f moves
`away from the spring e, so that an elastically-
`mounted plate e’ presses the paper strip h
`onto the numbers of the disk b to print the
`numbers on the strip. The spring eis lifted
`sufficiently off the disk immediately after this
`function by asmall spiral situated in frontof
`the guide-barg, so that the spring ¢ does not
`interfere with the rotation of the disk 0.
`In order to obviate any possible failure in
`the operation of the disk b, the latter is loose
`on its axle and is compelled to follow the ac-
`tion of the clockwork by springs 7 7’, fixed to
`the disk and bearing against pins. There-
`fore should the disk 6 be momentarily stopped
`the clockwork may continue in its motion.
`Pins o are provided on the disk 6 between the
`numbers and the periphery of the disk 0 at
`distances equal to the correct distances be-
`tween the eenters of the numbers, so as to in-
`dicate exactly the accurate distances between
`theoretically correct centers of the numbers,
`so as to show the seconds with certainty and
`accuracy. A fixed pin p is situated on the
`bridge ¢ and indicates exactly the center of
`the spring e when the latter strikes down, so
`that the fractions of seconds can he easily
`read from the strip of paper.
`In the apparatus as shownin the drawings
`the spring e may be raised into its original
`position by hand; but the apparatus maybe

`
`rranged so that the spring is raised into its
`original position by clockwork, which latter
`may also move the paper strip..
`It will be casily seen that the whole appa-
`ratus may be arranged automatically, so that
`the person measuring the time need only press
`the ball when the horse passes the distance-
`posts, the spring being returned automatic-
`ally after the registering of the time and the
`advance of the strip of paper being also ef-
`fected antomatically.
`arace maybe registered by anyobserver with-
`out interruption.
`The apparatus may comprise several strik-
`ing-springs and several strips of paper, so that
`several persons may simultaneously register
`the running of different race-horses.
`The registering may be done in ink orcolor
`by the use of ink or colorribbons, andby trans-
`ferring the differences of the numbers regis-
`tered on the strip to squared paperdiagrams
`may be produced which show the progress of
`a race at a glance.
`What I claim, and desire to secure by Let-
`ters Patent, is—
`1. In a device for measuring time at race-
`courses,
`the combination of a disk having
`raised numbers at certain distances apart, a
`spring ¢ above the disk carrying an impres-
`sion-pad e¢’, a guide-rod forsaid spring, means
`for leading a strip of paper betweensaid iin-
`pression-pad and the disk, clockwork forro-
`tating said disk at a uniform speed, and
`
`Thus the progress of| 643,592
`
`spring-arms for connecting said clockwork to
`said disk so that the clockworkis not inter-
`fered with or impeded by the taking of an im-
`pression, substantially as described.
`2. A device for measuring time at races con-
`sisting of a box a containing the apparatus
`consisting in combination of a disk 6 having
`raised numbers at certain distances apart, so
`that at the rotation of the disk b for a second,
`it is moved a distance, corresponding exactly
`to the distance between the numbers; one or
`more striking-springs e effecting the register-
`ing of the time by its or their disengagement
`and which byits or their descent press a paper
`strip % onto the disk b and thus print the
`time; a clockwork ¢ driving the disk which
`is adapted to continue uniformly the time-
`measuring operation, even if the disk 6, be
`momentarily stopped, by the spring e, by rea-
`son of springs 7 1’, which, connecting the disk
`to its axle, can yield, and the disk when lib-
`erated can come up with the axle; a fixed
`striking-pin p allowing fractions of seconds
`to be read; and means forthérelifting of the
`| spring ¢ after striking andfor the advance of
`the paperstrip / either by hand or automat-
`leally, substantially as deseribed.
`In witness whereof Isubscribe mysignature
`in presence of two witnesses.
