APPARATUS FOR LOCATING OBJECTS Filed oct. 12. 1929 Patented Oct. 18, 1932 UNITED STA-TES PATENT OFFICE i f CHARLES W. ROBBINS, OF LA GRANGE, ILLINOIS, ASSIGNOR TO WESTERN ELECTRIC COMPANY, INCORPORATED, OF NEW YORK,KN. Y., A CORPORATION OF NEW 'YORK APPARATUS FOR LOCATING OBJECTS Application filed October 12, 1929. Serial No.-399,184.
This invention relates to an apparatus for locating objects and more particularly to an apparatus for locating objects desired to be exposed to radiant waves, as, of light.
An object of the invention is to provide an apparatus for locating objects which will be inexpensive to manufacture, and simple and convenient to use.
The invention contemplates the provision of a circular cover plate or glass which isk secured in an annular frame and carried on one end of an arm. The arm is pivoted at an intermediate point upon a bracket which is slidably secured upon the glass object slide of a microscopic or similar observing device, and is equipped with a spring to normally maintain the cover glass in a predetermined position over the object being observed.
A better understanding of the invention will be secured from the following detailed description, when considered in connection with the accompanying drawing, in which Fig. 1 is a plan View of one embodiment of the invention;
Fig. 2 is a section taken on the line 2 2 of Fig. 1, and
Fig. 3 is a section taken on the line 3-3 of Fig. 1. A
Referring to the drawing in which similar parts are indicated by identical reference numerals, a glass object slide 10 of the type commonly used in microscopic examinations to hold the specimen or object to be examined, is characterized by a left end 11, a right end 12 parallel therewith and respectively parallel opposing edges 14-14. As shown in Fig. 3 the edges 14-14 are provided with gradually tapering beveled edges 1-5-15 which may be ground or otherwise suitably imparted thereto. For use in conjunction `with the object slide 10 a bracket 16 preferably of sheet metal is provided having depending side portions 17-17, each of which is bent slightly inwardly to coincide with the surface of the beveled edges 15-15. The bracket 16 is provided at each end thereof with oppositely disposed ears 20-20 which extend upwardly from the bracket 16 or in an opposite direction with respect thereto than the depending portions 17A-17:l Theiears 20-,20
`are perforated to receive a rod22 which extends longitudinally of the bracket so as to constitute an axis for a tube 23 and permit its free rotation therearound. is secured by solder or other suitable agency to thetube 23 at a point approximately midway of its .ends and is there bent through an angle of approximately degrees to form at the right side of the tube a` handle 25. On the other side of the tube the arm 24 extends in the manner shown in Fig. 1 and is provided with an annular frame 27 which is soldered or otherwise aflixed thereto. As
shown in Fig. 2, the annular frame 27 is pro- .Y
ner in such fashion that its lower surface is An 'arm 24 55 flush with the lower surface -of the annular I frame 27. A spring'31 having its ends braced upon the surface of the bracket 16 is looped over the arm 24 for the purpose of insuring that the cover glass 2,9, though movable perpendicularly with respect to the object slide, will normally be urged to lie flush upon the surface of the object slide 10.
In operation the bracket 16 may be moved over the right end`12 of the object slide 10 with the flanges 17-17 projecting beyond the lower surface ofthe slide. Due to the taper of the edges 14-14, the bracket 16 may be moved longitudinally over the-objects slide until the full width of the slide contacts with the depending portions 17-17 of the bracket,
`at which point it will be found that a slight to lower the cover glass upon the object and exert a continual pressure ,thereon to prevent 10u movement or dislocation of the obj ect during i examination. As soon as the examination is finished or When it is desired to release the specimen the handle 25 may be again depressed, the cover glass lifted and the specimen removed. Itshould of course'be clearly understood that the foregoing designations of annular frame 27 and circular cover glass are but convenient forms employed, and the shape of the parts referred to may be changed to rectangular, oval, etc. Without departing from the spirit of the invention.
Although the embodiment disclosed is primarily intended for use'in connection with a microscope, and in cases Where for instance, the objects desired to be examined are not intended for preservation, or in case for other reasons it is deemed unwise to cement them to the object glass as has been often necessary heretofore, the invention is clearly applicable in all cases Where it is desired to cover any object sought to be subjected to types of radiant energy in addition to microscopic Work.
What is claimed is:
l. In combination with an object slide, a
bracket longitudinally slidable With respect to the slide, a cover glass mounted on the bracket and spring actuated means for constantly urging the cover glass toward the object slide. i
2. In combination With an object slide, a bracket longitudinally slidable with respect to the slide, a cover glass and spring actuated means mounted on the bracket for constantly urgjngv the cover glass toward the object slide. l
3. In combination With an object slide, a cover glass, spring means for constantly urgng the cover glass toward the object slide, and a bracket mount-ed on the object slide and movable longitudinally relative thereto for carrying the cover glass and the spring means.
4. In combination with an object slide, a bracket longitudinally slidable With 'respect to the slide and having a pivoted arm thereon movable vertically With respect to the slide, and a cover glass mounted on the arm.
5. In combination with an object slide, a, bracket longitudinally slidable With respect to the object slide and having a pivoted arm thereon and movable vertically with respect to the object slide, a cover glass mounted on the arm, and means mounted on the bracket and effective on the arm to constantly urge the cover glass toward the slide.` Y
6. In combination with an object slide, a bracket having depending members for engaging the edges of the object slide` and pergaging the'bracket and thearm for constantly urging the cover glass toward the object slide.
7 In combination with an object slide, a bracket having depending members for engaging the edges of the object slide and al- CHARLES W. 'ROBBINS
