Patented Oct. 10, 1944 UNITED STATES PATENT OFFICE MICROSCOPE Albin A. Gradisar and Gustav E. Guellich, Bu!- falo, N. Y., assignors to Spencer Lens Company, Bunalo, N. Y., a'. corporation of New Yorkv Application my 21, 1942, serial No. 444,642
7 Claims. (Cl. 'J7- 5) This invention relates to tools or the like and has particular reference to a new and improved tool having optical sighting means whereby the tool may be aligned with the work.
An object of the invention is to provide a new and improved device having optical sighting means for aligning the tool with the work and allowing use of the tool without the necessity of removing any of the optical members and without movement or possibility of injury thereto.
Another object of the invention is to provide a new and improved device having sighting means whereby a tool may be aligned with the work and which allows removal of the tool at any time for observing the effect of the tool on the work.
'Another object of the invention is to provide a device adapted to support a tool relative to the work and having sighting means for positioning the tool relative to the work and said sighting means being so associated with the tool support Over the upper end of both the inner casing 2 and outer casing I is the cover member B to which lens elements 3 which may be of desired form.
The sighting arrangement 'l comprises the eyepiece lenses l0 and the reticle II and right angle or reflecting sighting prism I2. This reticle II preferably has the target thereon in the form of concentric circles with a central cross hair. This sighting arrangement allows the operator to sight into the eyepiece I0 through the optical members in said members 1 and 8 and through the opening in the lower end of the inner casing 2, and align the center of the cross hairs on the target with the spot on which the tool is to be placed so that the drill or other tool is properly aligned with the work and then the drill or-other tool is inserted in said opening that movement of the tool can be eected without any movement of the sighting means.
Other objects and advantages of the invention will be apparent from the following description taken in connection with the accompanying drawing and it will be understood that many changes may be made in the details of construction and arrangement of parts without departing from the spirit of the invention as expressed in the accompanying claims. We therefore do not wish to be limited to the exact details of construction and arrangement of parts shown and described as the preferred form has been shown by way of illustration only.
Referring to the drawing: Fig. 1 is a sectional view taken through one form of apparatus embodying the invention; and Fig. 2 is a sectional view taken through another form of apparatus embodying the invention.
Referring more particularly to the drawing wherein similar reference characters designate corresponding" parts throughout the several views, the form of the de'vice shown in Fig. 1 comprises an outer casing I an inner rotatable casing 2 rotatably mounted within said outer casing I and adapted to rotate within said outer casingIontheballraces3. A
The inner casing 2 is adapted to support a drill or the like at its lower end I and is also provided with a pulley or the like 5 adapted to receive a belt for rotation of said inner casing 2 although it will be understood that if desired said inner casing 2 may be so constructed as .to be rotated by means of a suitable gear system.
4 in the lower end of the casing and said casing 2 rotated by means of the belt or gear or other mechanisms described above to cause the tool to operate upon the work. I1' at any time it is desired to inspect the work it is only necessary to stop the rotation of the tool and remove the tool and inspect the work after which the tool can be replaced as described above for further operating upon the work.
It is pointed out that instead of employing the pulley or gear mechanism that an armature winding I8 may be positioned around the casing 2 for eifecting rotation thereof.
It is particularly pointed out that with the present construction it is not necessary to remove any of the optical parts as has been necessary with prior constructions and also that the sighting arrangement 1 and lens tube 8 do not rotate during the drilling operation as they did with prior constructions. therefore eliminating any with suitable gear or othermechanism as described above.
The casing I3 is provided at its lower endwith a sighting opening l1 having suitable means for supporting the drill or other tool.
It will be seen that this form shown in Fig. 2
the operator sights through the sighting arrangement I5 and lens tube i4 and opening l1 until the position for the tool is suitably aligned with the work and then the tool is placed in the holder Il and the casing i3 is rotated by a pulley or gear mechanism to cause the drill or other tool to operate upon the work in a manner similar to that described for the form shown in Fig. 1
above.
While the apparatus has been described in connection with a drilling tool it will be understood that the use of said apparatus is not necessarily limited to use with a drilling tool but that the device may be employed in connection with other desired tools.
From the foregoing it will be seen that we have provided simple, emcient and economical means to obtain all of the objects and advantages of the invention.
