(GRANTED UNDER THE ACT OF MARCI-I 3, 1883, AS AMENDED APRIL 30, 1928; 370 0. G. 757.)
The invention described herein, if patented, may be manufactured and used by or for the Government for governmental purposes without the payment to me of any royalty thereon.
The subject of this invention is a data computer.
The principal object of the present invention is to provide a compact structure in a computing device which will permit the utilization of both sides of a rotatable member and enable the readings to be made from any position.
With the foregoing and other objects in view, my invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
A practical embodiment of the invention is illustrated in the accompanying drawings, wherein:
Fig. l is a view in side elevation showing the invention applied to a data computer;
. Fig. 2 is a longitudinal sectional view of Fig. 1 taken at right angles to the plane of said figure;
Fig. 3 is a view in elevation showing an application of the invention to a fire control apparatus for ordnance;
Fig. 4 is a similar View showing its association with a telemeter;
Fig. 5 is a similar view showing an application to a weighing device;
Figs. 6, 7 and 8 are views in elevation illustrating a modification of the invention with various arrangements of prisms;
Fig. 9 is a diagrammatic View.
Referring to Figs. 1 and 2 the invention comprises a rotatable drum 5 whose inner and outer surfaces are provided, respectively, with scales or charts 6 and 7. Mounted for movement parallel to the axis of the drum is a slide 8 having one arm 9 disposed exteriorly of the drum and another arm 10 disposed within the drum. The outer arm is provided with a reading mark in the form of a cross hair 11 for indicating against the outer scale 7 and the inner arm carries a prism 12 in scribed with a cross hair 13 for reflecting a portion of the inner scale 6 to a point outside of the prism, preferably through a stationary prism 14 mounted on the slide support 15.
The arrangement lends itself admirably for the determination of firing data for anti-aircraft guns. In order to calculate the deflection corrections and the fuse range to the predicted future position of an aerial target the values of the present position must first be resolved. In the diagram in Fig. 9 wherein G represents the gun, T the target, a the angle of site, and h the altitude it is possible to determine the slant range R, the fuse number F, the angle of superelevation band the total angle of the elevations 0.
An application of the invention to an apparatus for resolving the foregoing problem is shown in Fig. 3 wherein an upright support 16 mounts a top carriage 17 movable in azimuth through the gearing indicated at 18. On the top carriage is a cradle 19 carrying a telescope 20 and gearing 21 for moving the telescope in elevation.
The drum 5 shown in Fig. 3 is mounted on the axis 22 of the telescope so that as the telescope follows the target the drum will be rotated in function of angle of site. The slide 8 is mounted at the opposite side of the cradle and is provided with a scale 23 readable against a fixed index 24 so that it may be displaced by the gearing 25 to afford a measure of the altitude of the target. WVit-h the functions of angle of site and altitude thus represented the other elements of the equation may be determined by means of appropriate scales 6 and 7. The scales in this example will consist of a family of curves plotted in function of angle of site and altitude to read either slant range, fuse member, superelevation or total elevation. lVhen it is desired to read the angle of site indicated by the telescope a pointer 26 may be mounted to read against the scaled rim 27 of the drum.
In 4 the drum and slide are shown in association with a telemeter 28 whose axial rotation affords a measure of the angle of site and whose altrimetric mechanism supplies the function of altitude.
Instead of having the inner and outer scale serve in determining different functions, they may be used to determine the same function but in different values as shown in Fig. 5. As an example the drum may be displaced in terms of weight and the exterior arm 9 of the slide 8 may be provided with a dual set of figures indicating price. Such figures, for example, would read from 3 to 10 and from 11 to 22. The set from 3 to 10 would correspond to the total price figures or curves on the outer scale and the other set, although having the same displacement as the first set would correspond to the figures or curves on the inner scale.
' In the modifications shown in Figs. 6 to S a rotatable disk 29 is substituted for the drum 5 and carries the scales 6 and 7 on its sides and also a peripheral scale 30. In Figs. 6 and 7 the prisms 81 and 32 are arranged to reflect the scales 6 and 7 into a common reading plane and in Fig. 8 the prisms are disposed on opposite sides to permit reading in parallel planes. In some cases it may be desirable to read the same values from 'ditl'erent planes without complicating the optical systems, and under such circumstances the scales 6 and 7 would be identical and the prisms arranged as in Fig. 8.
I claim: 1. In a data computer, a support, a sighting instrument mounted on the support for determining angular elevation, a drum rotatable with the axis of the sighting instrument, a slide mounted on the support for movement parallel to the axis of the drum and provided with arms disposed one within the drum and one exterior of the drum, means for displacing the slide proportionately to altitude, a chart on the inner and outer sides of the drum having a family of curves plotted in terms of the determined functions to indicate functions related'thereto and means on the arms of the slide whereby the inner and outer charts may be read.
2. In a data computer, a member rotatable proportionate to a determined function, sliding means movable parallel to the inner and outer sides of said rotatable member in proportion to another determined function, a chart on each side of said rotatable member indicating resultants of the determined functions and means on the sliding means whereby each of the charts may be read.
