PATENT OFFICE.
TELESGOPE.
Specification of Letters Patent.
Patented Sept. 21, 1920.
Application led December 26, 1919. Serial No. 847,495.
To all whom. t may concern.'
Be it known that I, MICHAEL LIGHTMAN, a citizen of the United States, and a resident of the city of New York, (borough of Manhattan,) county and State of New York, have invented a new and Improved Telescope, of which the following is a full, clear, and exact description.
This invention relates to telescopes, and has reference more particularly to novel means for securing an eye piece and object glass to said telescope, and also a catch which is adapted to secure the barrels of said telescope in a plurality of positions.
An object of this invention is to provide a telescope which is simple of construction, so that it can be manufactured at a low cost.
Reference is to be had to the accompanying drawing forming part of this specification in which it is understood that the drawing is merely illustrative of one example of the invention, and in which- Figure 1 is a central, sectional view through the telescope in a collapsed position.
Fig. 2 is a fragmentary, central, sectional view on a large scale of the telescope elongated.
F ig. 3 is a section through Fig. 1 on the line 3 3.
Fig. 4 is a section through Fig. 1 on the line 4 4.
Referring to the accompanying drawing by numerals, 10 indicates the outer barrel of a telescope having an inner barrel 1l, and a plurality of intermediate barrels l2. The outer barrel is provided on one end with a ring 13 having an annular flange 14 at right angles thereto, said flange being adapted to grip the barrel and x sald ring thereto. An object glass 15, smaller in diameter than the internal diameter of the barrel 10 rests on the ring 13 and is secured thereto by an annular ring 16 which may be any material but is preferably made of paper which is Flued both to the object glass 15 and to the rin 13. the object glass 15 and the end of each of the intermediate barrels 12 is provided with an annular ring 17 litted thereto which has an annular flange 18 at right angles to said ring. Each of the annular rings 17 is provided with an annular groove 19 which The end of the barrel 10 opposite.
serves to secure the ring 17 to the barrel 10, and to provide a means for engaging a ball 2O fixed to the end of a flexible finger 21, said fingers being fixed to the rings 17 by any suitable means such as solder.
The end of the inner barrel 11 opposite the object glass 15 is provided with a cap 22 which is an irregular shape in cross section as shown in Fig. 1. This cap is provided with an annular flange 23 which engages the end of said barrel 11, said flange being provided with an annular groove 24 similar to the grooves 19 and having a similar purpose. The cap 22 is provided with a peep hole 25 through which the line of vision may be directed. The eye piece 26 is fixed to the insideV of the barrel 11 adjacent the cap 22 by means of an annular ring 27 on one side of said eye piece, and a ring 28 on the other side of said eye piece said annular rings being glued together and also glued to a cylindrical stop 29` said stop being glued to the inside of the barrel 11. The ends of the barrels 11 and 12 adjacent the object glass 15 have fitted to them a plurality of rings 30, each of which has an annular groove 31 pressed in its outer surface, said groove serving to fix said ring to the barrels and also serving to engage the balls 20 as the telescope is elongated. Any number of these rings 30 may be fixed in intermediate positions on the barrels so that the balls 20 will snap into position in various intermediate points where a focus on a distant object is obtained. In Fig. 2, two of the barrels are 'shown elongated with the ball engaging the annular groove, thus fixing the barrels in this definite position.
I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of the invention as defined in the appended claim.
Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:
A telescope consisting of a plurality of concentric barrels in slidable' relation to each other, an annular ring secured to one ond of each barrel, an annular groove formed or more annular rings formed on each o1 in each ring adapted to grip said barrels and said barrels, an annular groove formed on secure said rings to said barrels, a. ilexible each of the last, mentioned rings ada ted to 10 linger xed to ea'oh of said rings, a ball oit engage the balli im nucl Secure sacl e escupe! 5 the end of each of said ngers adapted to barrels in a plurality of intermediate posiengage one of said annulardgrooves When tv ons. the telescope is in a colapse p-asitin, one MCHAEL LICHTMAN.
