Abstract

Abstract A speed register intended for thoroughbred racing (flat) is disclosed in a circular slide embodiment and in a straight slide embodiment. The circular slide has a base provided with an annular elapsed time scale and a set of corresponding speed readout scales spaced therealong according to individual race distances. The circular slide embodiment includes a set of rotary discs and cursors secured by a pair of eyelets to accommodate relative shifting movement. The straight slide embodiment includes a plurality of base scales each associated with common cursor elements, with the base scales being relatively shiftable to portray relative performance factors simultaneously with direct speed readouts. A pivoted base scale also enables conversion of past performance data between tracks having different speed characteristics.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 232 words
A multidistance racing speed register comprising a circular baseplate provided with time indicia defining a linear elapsed time scale in fixed relation along said baseplate and provided with speed indicia defining a plurality of speed scales, each representative of an individual predetermined distance, disposed at predetermined fixed locations along said baseplate, each speed scale spanning a common predetermined speed value range and each extending alongside a portion of the elapsed time scale for which the speed indicia of the particular speed scale correlate with the time indicia in accordance with the absolute speed formula S D/T where S is given in units of length per unit of time, D is given in units of length and represents the predetermined distance to which the speed scale corresponds, and T is given in units of time; said speed indicia for each speed scale including integers successively angularly spaced nonlinearly along each individual speed scale, with the equal valued integers on said speed scales being spaced apart in direct linear proportion to the difference between the predetermined distances represented by said speed scales; a second member having pointer means; and guide means shiftably connecting said members for relative movement for positioning said pointer means relative to said scales such that the pointer means, when aligned with any value on the elapsed time scale, indicates the speed corresponding to such value on the corresponding speed scale.
Claim 2
Dependent Claim 232 words
A multidistance racing speed register comprising a circular baseplate provided with time indicia defining a linear elapsed time scale in fixed relation along said baseplate and provided with speed indicia defining a plurality of speed scales, each representative of an individual predetermined distance, disposed at predetermined fixed locations along said baseplate, each speed scale spanning a common predetermined speed value range and each extending alongside a portion of the elapsed time scale for which the speed indicia of the particular speed scale correlate with the time indicia in accordance with the absolute speed formula S D/T where S is given in units of length per unit of time, D is given in units of length and represents the predetermined distance to which the speed scale corresponds, and T is given in units of time; said speed indicia for each speed scale including integers successively angularly spaced nonlinearly along each individual speed scale, with the equal valued integers on said speed scales being spaced apart in direct linear proportion to the difference between the predetermined distances represented by said speed scales; a second member having pointer means; and guide means shiftably connecting said members for relative movement for positioning said pointer means relative to said scales such that the pointer means, when aligned with any value on the elapsed time scale, indicates the speed corresponding to such value on the corresponding speed scale.
Claim 3
Dependent Claim 46 words
A register in accordance with claim 1 wherein said guide means comprises a pivot element centrally in said base member and mounting said second member for rotation thereabout, said elapsed time scale and said speed scales being arrayed annularly about said pivot element as a center.
Claim 4
Dependent Claim 142 words
A register in accordance with claim 1 wherein said guide means comprises a pivot element and wherein said base member is a base disc having a central opening receiving said pivot element and having said elapsed time and speed scales arrayed annularly about said opening as a center, said second member is a transparent disc having a central opening registering with said first opening, receiving said pivot element and having a radial hairline to overlie said elapsed time and speed scales, said transparent disc having lengths indicia providing an annular scale calibrated relative to the elapsed time scale, registered with said hairline and arrayed annularly about said pivot element, and a cursor rotatable on said pivot element and overlying said transparent disc and having a radial hairline to intersect all of said scales to provide direct speed readout from lengths differential data.
Claim 5
Dependent Claim 56 words
A register in accordance with claim 3 wherein said cursor has a U-shaped finger grip end trained radially around the outer periphery of said base disc, said cursor having a flush overlying relation to said transparent disc to rotate in unison therewith, said grip end being engageable to rotate the cursor relative to the transparent disc.
Claim 6
Dependent Claim 66 words
A register in accordance with claim 3 wherein an eyelet constitutes said pivot element and rotatably connects a subassembly of said base disc, said transparent disc and said cursor, said eyelet including end flanges retaining said subassembly, said subassembly including a first washer encircling said eyelet and disposed intermediate said discs and a second washer disposed between said cursor and one end flange of said eyelet.
Claim 7
Dependent Claim 140 words
A register in accordance with claim 5 wherein a second eyelet extends through and beyond the first-named eyelet, a third disc disposed adjacent said base disc and encircling the other end flange of the first-named eyelet, and a second cursor rotatable on said second eyelet between said base disc and said third disc, said second eyelet having end flanges engageable at one end with said first-named eyelet and at the other end with said second cursor, said base disc having a totalizing scale extending circularly about said opening on the side thereof facing said third disc, said third disc having a set of successive racing factor scales extending circularly thereon for register individually with the totalizing scale, and said cursor having a hairline for transposing readings in additive relation from each of said rating factor scales to said totalizing scale.
