Oct. 14, 1940. w. HAAG-sTRElT INSTRUMENT SUPPURT Filed may 1o. 193s INVENTO flag; jlu/ 4. /MIW ATTORNEY Patented Oct. 1, 1940 UNITED STATES INSTRUMENT SUPPORT Wilhelm Haag'- Streit, Bern, Switzerland Application May 10, 1938, Serial No. 207,169 v In Germany May 13, 1937 5 Claims.
My invention relates to improvements in base carriages for the adjustment of the standards of eye-examining instruments; and the principal object of my improvement is to materially simplify both the structure and the operation of such base carriages and, therefore, to speed up the setting up and adjusting operations necessary for such examinations.
The adjusting devices incorporated in the base carriages of this class of instruments commonly comprise cross slides the component parts of which are vertically and horizontally adjustable by means of rack-and-pinion aggregates, each displacement in any of the three spatial directions requiring a special aggregate. In the latest types of such instruments the operating knobs for the said aggregates are mounted concentri- `cally or, respectively, co-axially with each other.
My improvement relating to devices for the spatial adjustment of base carriages for the operation of eye-examining instruments eliminates these rack-and-pinion drives and cognate pinion aggregates used heretofore for displacing th cross slides, the latter instead being actuated by means of a single lever displaceable in all directions.
The base carriage, according to my present invention, preferably is mounted, on the one hand, longitudinally displaceable on a shaft which itself may be displaced parallel to itself and the ends of which may slide or roll on a suitable type of track, and which, on the other hand, is supported on a slide base or on rollers, so as to enable one to move the carriage parallel to itself by means of the single operating lever.
I, furthermore, preferably connect a ball or roller-serving as a third point of support-with the operating lever, the latter thus serving as a displacement handle for the purpose of a preliminary setting and as a swing lever for the said ball or roller for the purpose of the nal adjustment of the instrument.
I attain the object stated by the device illustrated-by way of an examplein the accompanying drawing, in which-- Fig. 1 is a side elevation, partly in section; and
l Fig. 2, a plan view of the device with parts broken ing 6 is fastly connected to the latter and may be axially displaced on a shaft 8 which is supported on ball-bearings 1. A guide sleeve 9 for the instrument standard I0 is fastly connected to the said tube 6. The vertical displacement of the instrument standard is effected-in a manner known-by revolving the knurled knob II. The said shaft 8 at each end is fastly connected to a suitably knurled disc I2 which rolls on a track I3 preferably'made of rubber. A pin I4 projects from each end of the said shaft 8 and serves, in combination with a rail I5, for limit ing the parallel mo-tions of the shaft 8. The said rails I5 at the same time prevent the derailing of the instrument oli` the tracks I3. A track plate I6 on the instrument table I'I also is provided for the said roller 3.
For the purposes of a preliminary setting the operating lever 5 is not actuated but simply is used as a handle for bodily displacing the entire carriage and instrument in the desired direction. This is done by gripping the lever 5 and displacing it, together with the carriage I, in the direction, e. g., of the arrow a of Fig. 2; the carriage thus moving on the roller 3, which latter slides on the track plate I6, in the same direction, and the tube 6 displacing itself with the instrument standard III in the same sense on the shaft 8, the latter not changing its position.
If, however, the lever 5 is drawn in the direction of the arrow b, not only the carriage I but also the shaft 8 and the tube 6 follow this movement; the latter, however, remaining stationary with respect to the shaft 8. It is obvious that by means of the lever 5 used as a handle also composite movements, i. e. movements forming an angle with the arrows a or b, of the entire base carriage may be executed, during which the roller 3 is sliding obliquely over the track plate I6 and during which a movement of the tube 6 along the shaft 8 `is taking place simultaneously with a parallel displacement of the shaft 8 with its discs I2.
For the purposes of a nal adjustment, however, the lever 5 is used as a swing lever, i. e. it is either rotated together with the roller 3 about the axle 4b in the fork 4 or about the axle 4a. Movements in an oblique sense also may be effected by means of correspondingly directed swing movements of the lever 5.
What I claim and desire to secure by Letters Patent is:
1. An instrument support comprising a base, a shaft adaptedto roll on said base, a slide serving as the instrument mount longitudinally slid- 3. An instrument support comprising a base, a
shaft rolling on said base, a pair of guides mounted on said base guiding the rolling of said shaft, a slide serving as an instrument mount longitudinally slidable on said shaft and a universally mounted lever in said slide for adjusting said. slide to the desired position.
Il. An instrument support comprising a base, a shaft adapted to roll on said base, a slide serving as an instrument mount longitudinally slidable on said shaft, a second shaft rotatably mounted in said slide, a fork xed to said second shaft and a roller rotatably mounted in said fork for shifting said slide to the desired position on said base.
5. An instrument support comprising a base, a shaft adapted to roll on said base, a slide serving as an instrument mount longitudinally slidable onsaid shaft, a second shaft rotatably mounted in said slide, a fork xed to said second shaft, a roller rotatably mounted in said fork and a lever fixed to said roller for operating said roller in cooperation with said base so as to adjust said slide to any desired position on said base.
