BACKGROUND OF THE INVENTION This invention relates to a speed register for provid ing direct comparisons of past performance data for race contests run over a variety of known distances. The invention enables a truly empirical approach to the analysis and correlation of the past performance data.
In most race contests, such as thoroughbred racing (fiat), standard bred (harness), quarter horse racing, greyhound racing, track and field racing and motor boat and automobile racing, the events are conducted at a variety of different but known distances and the results are reported by distance and time with no specific report on speed in terms of distance. In many instances, only the running time for the winner is given and the runnerups are reported in relation to the number of lengths behind the winner at the finish line. This information enables reasonably accurate estimates of the running times for each contestant. There is given, in addition, in most instances, the running time for the leader at predetermined intermediate points of call" or fractions of course distance and the number of lengths behind at each such point of call is given for each of the other contestants.
There is also given in the statistical reports much ad- I ditional data depending on the type of contest, such as track condition, wind effects, weight carried and the like. It must also be remembered that the racing contests are conducted over a variety of distances, so that comparison of running times becomes impractical and requires a departure from absolute and empirical standards.
In short, the statistical data which is available is vast and appears very complex to even the experienced analyst. While speed is the ultimate factor in any racing contest, scant, if any, specific data is given for speed and much confusion results in the evaluation of the past performance data where distances are not identical. In sports such as horse racing and greyhound racing, the true speed capabilities are important not only for use in selecting speedy performers for future events but for selecting the proper competitive level and for making evaluations of breeding lines both to improve the breed and to aid in selecting yearlings based on breed lines.
DESCRIPTION OF THE PRIOR ART Many shorthand approaches and devices for combining various factors in the performance data are availa 2 SUMMARY OF THE INVENTION In accordance with the present invention, a multidistance racing speed register is provided to assimilate the diverse past performance data and give a direct readout of absolute speed in terms of distance per unit of time. Average absolute speed for the entire distance and average absolute speed values at fractional distances can be registered. Changes in absolute speed during a particular race also show up the ability of a particular entry to accelerate. Not only does absolute speed enable comparisons between performances at different distances but it provides a frame of reference against which the effect of other variables such as track condition, weight and the like may be judged in relation to each performer.
The multi-distance racing speed register comprises a pair of relatively movable members, one having an elapsed time scale extending therealong and having a plurality of individual speed readout scales spaced therealong according to individual race distances, the speed scales each including a common range of speed values representative of typical speeds attained at the various distances, each speed scale being positioned along a portion of the elapsed time scale for which the speed values correlate with the time values in relation to the particular distance which such speed scale represents, the other member having a pointer to align with a time value and a speed value for the same distance.
Other features and advantages of the invention will be apparent from the following description and claims, and are illustrated in the accompanying drawings which show structure embodying features of the present invention and the principles thereof.

DESCRIPTION OF PREFERRED EMBODIMENT Referring now to the drawings and particularly to FIGS. 1, 2 and 3, the illustrated embodiment of the in vention shows a register 10 of the circular slide type andcalibrated for thoroughbred turf racing. It is to be noted that the register can be embodied as a straight slide type.
For example, in thoroughbred turf racing, nearly all of the races fall into certain standard distance categories, such as 5 furlongs, 5%, 6, 6%, 7, 7%, 8 (l mile), 8%, 9.9% and 10. There are shorter distances for young 2 year olds and longer distances for a few special events. In general, however, the average speed for a contestant capable of contention is in a range from about 48 fi/sec to about 60 ft/sec. ln longer races, such as furlongs, the average speed range is from about 52 ft/sec to about 57 ft/sec. For shorter races, or for fractions of a long race, the average speed range may exceed the 52 to 57 ft/sec range.
In other sports, such as standard-bred sulky racing and greyhound racing, the particular race distances and the typical ranges of average speed values are different so that different speed scale calibrations are required. For purposes of illustrative disclosure, the particular values are given herein in detail for thoroughbred turf racing and only certain general value relationships are provided herein for sulky and greyhound racing. For example, for quarter horse racing, the average speed range is from about 58 to 60 feet per second and for greyhound racing, the average speed range is from about 49 to about 55 feet per second.
1n the circular slide type of thoroughbred speed register shown in FIGS. 1, 2, and 3, the device includes a base member 11 which is provided with a central stub eyelet 12 that receives an indicator dial l3 and a cursor 14. A plastic washer 15 of about 0.010 inch thickness encircles the eyelet l2 and is sandwiched between the base 11 and the indicator dial 13 to maintain free relative rotation therebetween and opposite ends of the eyelet are rolled outwardly to provide upper and lower retaining flanges 12A and 12B, respectively. A nylon washer 16 is disposed between the upper flange 12A and the cursor arm 14 to allow relatively free rotation thereof, while the lower flange 12B engages directly against the base 11 which, being of largest diameter, is normally to be held stationary in the hands of the user while the remaining elements are manipulated to various rotary positions.
The subassembly defined by the stub eyelet 12 is telescoped over a central eyelet 17 that also receives a cursor 18 and a rating disc 19. Opposite ends of the central eyelet 17 are rolled outwardly to provide upper and lower retaining flanges 17A and 178, respectively. The cursor 18 has its inner periphery abutting the lower flange 12B of the stub eyelet which acts as an inner bearing therefor.
The eyelet 12 serves as a pivot shaft for guiding relative rotary movement between the base 11, the indicator dial l3 and the cursor 14. In addition, the cursor 14 is ridable with the indicator dial 13 to enable transfer of differential readings therebetween from one region to another. The cursor 14 has a U-shaped free end 14U bending around the periphery of the base 11 to facilitate finger manipulation of the cursor. The eyelet 17 serves as a pivot shaft for guiding relative rotary movement between the base 11, the cursor l8 and the rating disc 19.
The register incorporates two unique but complementary approaches to the analysis and use of past performance data. The top face of the base is pictured in FIG. 1 which also shows the transparent indicator dial l3 and the cursor 14 which are to be used in conjunction with the top face for making speed readings and adjustments. The bottom face of the base is pictured in FIG. 2 which also shows the cursor 18 and the rating disc 19 which are used in conjunction with the bottom face for weighting and totalizing various factors or criteria that have proven to be useful in evaluations of thoroughbred racing abilities.
Turning first to the speed register arrangement shown in FIG. 1, the top face of the base member 1 l is provided with an elapsed time scale 20 arrayed annularly about the pivot shaft and arranged in uniformly spaced divisions of seconds numbered from 0 to 135, also the minute-second equivalents from 0 to 2 minutes, 15 seconds are labeled on the elapsed time scale, with sub-divisions of fifths of a second in accordance with the present practice of reporting time data in fifths of a second. In the disclosed embodiment, the elapsed time scale is linear. At present, the time data reported for quarter horse racing and greyhound racing is given to l/ 10 of a second.
For each particular race distance of interest, the base member 1 1 is provided with a corresponding individual speed scale, the speed scale for 2 furlongs being designated 21-2, for 3 furlongs being designated 21-3 and so on up to 10 furlongs which is designated 21-10. Each speed scale is located in predetermined relation to the elapsed time scale in accordance with the typical range of running times for the particular distance. Thus, for the 6 furlong speed scale 2l6, the region of the elapsed time scale from 68 seconds to 76 seconds (that is, from 1:08 to l:l6) is spanned and the speed scale has a range from about 52 to about 58 feet per second. It may also be noted that in the illustrated embodiment, the speed scales are not linear in that the division spacing for one distance is different from that for other distances. Thus, on the 10 furlong speed scale 2l-l0, the difierential between speeds of 55 and 56 feet per second corresponds in time to the difierence between 120 and -4/5 seconds or 4-1/5 seconds of elapsed time. Correspondingly, on the 2 furlong speed scale 21-2, the differential between speeds of 55 and 56 feet per second corresponds in time to the dif ference between 24 and 23-3/5 seconds or about 2/5 of a second of elapsed time.
The scale divisions on the speed scale become small at the shorter distances where the elapsed time scale is linear but there is the advantage that the linear arrangement of the elapsed time scale extends almost full circle so as to simulate the effect of the familiar stop watch and thus is more understandable to the user who lacks technical background.
There is an important need for calculations of fractional race distances such as one or two furlongs. Past performance data frequently includes enough information to permit the calculation of speed during the beginning, the middle or the stretch but little, if any, practical use has previously been made of such information. In the illustrated embodiment, an expanded elapsed time scale and matching speed scale for a one furlong distance are shown at 20-1 and 2l-l, respectively, to facilitate accurate readings of speed for fractional race distances. in any event, it may be seen that there exists a common range of speed values 52 to 57 feet per second which is included in each speed scale 21-1 to 21-10. The invention is particularly useful because the thoroughbreds maintain a consistency in speed over a range of distances. A single simple device may thus cover the entire spectrum of racing abilities.
One of the primary uses for the computer 10 is to convert running times over different distances to speed in terms of feet per second. Thus, a particular horse may have a previous race run in 76-115 seconds at 6% furlongs, another in 83 seconds at 7 furlongs and others in a running time of 92-3/5 seconds at 8 furlongs and in l00 seconds at 8% furlongs whereas the next race is to be run at 7% furlongs. As indicated in FIG. 4, the indicator line or pointer 13L on the indicator dial 13 is set to a running time of 76-1/5 seconds to show an average speed of 56.4 feet per second for 6% furlongs, then the pointer 13L (as shown in phantom) is set to a running time of 83 seconds to show an average speed of 55.6 feet per second for 7 furlongs. As indicated in FIG. 5, the pointer 13L is set to a running time of 92- 3/5 seconds to show an average speed of 57 feet per second for 8 furlongs and (as shown in phantom) is set to a running time of 100 seconds to show an average speed of 56 feet per second for 8 V: furlongs.
In this example, one fact which stands out is that the horse should also be capable of running the 7% furlong race at 57 feet per second which was attained at the 8 furlong distance. Many additional analyses can also be made with reference to the calculated speeds. For example, if the horse carried more weight in the 6% and 8 furlong events than in the 7 and 8% furlong events for which slower average speeds are shown, it is reasonable to conclude that the horse is not weight sensitive. Moreover, if the horse has shown greater average speed on the grass than in flat racing, it can be concluded that grass races do not affect his speed. In any event, the purpose of the invention is not to decide how to handicap but rather to provide a tool for providing important empirical data based on the actual past performance data and giving an absolute standard for aiding in comparing the effect of the numerous other factors which are reported.
Of equal importance, is the potential use of the register to owners, trainers and breeders. The direct registry of speed gives added insight-to a horse's ability and leads to refinements in judging the condition and class of a particular horse and the overall value of the horses belonging to a particular breed line. Extension of the speed analysis to fractional times provides an indication of acceleration and this offers an entirely new measure of performance which has never been approached empirically.
The transparent indicator disc 13 has a lengths scale 22 centered on the pointer line 13L and marked off in lengths and each numbered 0 to 20. The lengths scale 22 is arranged at a location immediately radially outwardly of the elapsed time scale so that the parts may be arranged as shown in FIG. I for ease in registering speed readings from past performance data which gives the running time for the winner and the lengths behind for the trailing horses.
For example, in FIG. I, the line 13L is registered at 71 on the elapsed time scale indicating a running time for the winner of l minute and l 1 seconds for a 6 furlong race, giving the winner a speed of 55.6 feet per second. If a trailing horse finished 9 lengths behind, the base 11 and indicator disc 13 are held fixed and the cursor 14 has its hairline 14L set at 9 on the LENGTHS scale to show a running time of 73 seconds and a speed of 54.2 feet per second for the trailing horse. The lengths scale is made up on the basis of counting 1/5 of a second for each length. Similar readings may be made for each of the other trailing horses so that the past performance data may be set directly into the speed register of this invention for obtaining a direct readout in speed in terms of feet per second.
The indicator disc 13 also has a weight scale 23 arranged at a location immediately radially outwardly of the elapsed time scale 20 so that setting adjustments either of elapsed time or of speed may be made in accordance with weight changes. For this purpose, the indicator disc 13 is positioned so that the weight hairline 13W which is centered on the zero or no weight change point of the weight scale 23 is first aligned with the cursor hairline 14L which has previously been set for the particular past performance that is being analyzed. The indicator disc 13 is then held stationary while the cursor hairline is rotated clockwise along the weight scale to allow for a weight increase or counterclockwise to allow for a weight decrease.
While the invention emphasizes the value of developing direct empirical data on speed, provision is also made for developing a direct readout of speed factor. Thus, a correlation of speed factor and lengths scales 24, and 25, respectively, is provided at the beginning of the elapsed time scale which appears at the bottom of FIG. 1 and which is shown enlarged in FIG. 6. It is desired at times to establish a nominal reference value for speed rating numbers at 100. This 100 value may correspond to the world record or the track record for a particular distance or it may correspond to the speed of the winning horse in some particular race under analysis. Assuming the latter, the indicator disc 13 is set so that its hairline registers the lengths behind for the trailing horse, here represented as 15 lengths behind. The hairline 13L then gives a speed factor rating of for the trailing horse.
On the lower face of the base member 11, an annular totalizer scale 25 is provided at a location encircling the periphery of the rating disc I9. The rating disc 19 has a set of successive rating scales 26 to 30 arrayed as annular segments thereon and each representative of a different factor that has proven useful in the evaluation of thoroughbred racing abilities. In the disclosed embodiment, the totalizer scale 25 is linear and the rating scales 26 to 30 are logarithmic. Rating scale 26 is laid out in percent from 0 to based on the ratio of wins; rating scale 27 is laid out in percent from 0 to 50 based on the record of the owner; rating scale 28 is laid out in percent from 0 to 50 based on the record of the trainer; rating scale 29 is laid out in percent from 0 to 50 based on the record of the breed; and rating scale 30 is laid out in percent from 0 to 50 based on the record of the jockey. Numerous publications provide statistical data on these various factors and the disclosed register ar rangement provides a unique logarithmic totalizing of these factors.
To carry out a totalizing operation, the zero marks on scales 25 and 26 are registered and the hairline 18].. of the cursor 18 is set at the appropriate rating value (for example 40 percent) on the WINS scale 26. The cursor 18 is then held fixed relative to the scale 25 and the rating disc 18 is moved until the zero mark on scale 27 is registered with the hairline 18L. The rating disc 18 is then held stationary relative to the scale 25 and the cursor 18 is moved to set the hairline at the ap propriate mark on the OWNER scale 27. This sequence is repeated for each of the remaining scales until a total is derived at the reading of the hairline 18L on the totalizing scale.
While preferred constructional features of the invention are embodied in the structure illustrated herein, it is to be understood that changes and variations may be made by those skilled in the art without departing from the spirit and scope of the appended claims.
