TELESCOPIC MOUNTING.
SPECIFICATION forming part of Letters Patent No. 617,108, dated January 3, 1899.
Application filed July 80, 1898. Serial No. 687,345. (No model.)
To ctZZ whom it may concern.-
Be it known that I, CARL A. R. LUNDIN, a citizen of the United States, residing at Cambridge, in the county of Middle-sex and State of Massachusetts, have invented new and useful Improvements in Telescopic Mountings, of which the following is a specification.
This invention relates to improvements in telescopic mountings, and it is carried out as follows, reference being bad to the accompanying drawings, wherein Figure 1 represents a side elevation of the invention. Fig. 2 represents a central vertical section of the same; and Fig. 3 represents a cross-section on the line 3 3, shown in Fig. 1.
Similar letters refer to similar parts wherever they occur on the different parts of the drawings.
A represents a base-plate or support which may be stationary or portable, according to the desired use of the invention. WVhen portable, said base-plate is pivotally connected to tripod-legs B B B in the usual manner. To said base-plate A are secured a pair of brackets C C or cheeks provided on their interior faces with cylindrical projections O G, on which the cylindrical ring or polar-axis case 1) is journaled. The said brackets are provided with a friction clamping device, by means of which the case D may be frictionally clamped and held stationary relative to the brackets C C in the desired position during observations.
In diametrically opposite perforated hubs or projections 01 d on the ring or polar-axis case D is journaled the polar axle E, to the upper end of which is secured the sleeve e, in which is j ournaled the declination-axle F, provided at its upper end with a metal cradle f, to which the telescope G is secured in any suitable manner.
f is an adjustable clamping-nut on the spindle F, working on a screw-threaded portion of said spindle, for the purpose of securing the latter to the sleeve 6 after the telescope has been adjusted to the desired position or inclination. Said clamping-nut may also be used as a friction clamping device for frictionally holding the spindle F in position relative to the sleeve e to enable the operaring I, provided with lateral screw-threaded trunnions it, journaled in perforations in the brackets C C and provided with clamping or thumb nuts K K, as shown, Which serve for frictionally clamping the ring or case D between the brackets O O, and thus frictionally securing said ring in any desired position be tween the insides of said brackets G G. The ring I is held from turning preferably by having a notch or recess 11, adapted to receive a projection d on the interior of the ring D, as shown in Figs. 2 and 3.
By the construction as hereinabove shown and described it will be noticed that the polar axis E goes through the center of the polar axis case or ring and not outside of the latter, as is usually the case, by which arrangement the center of gravity of the instrument is brought in close proximity and very near to the center of gravity of the support, by which the best results are obtained. From the above it will be seen that the polar axle E may read ily be adjusted in a plane going through its axis, and it may also be rotated around its axis. The declination-axle F (to which the telescope is secured) may also be adjusted and rotated around its axis in the bearing-sleeve e and secured thereto after being adjusted.
The device is very simple and compact and is composed of very few parts by which the telescope may be universally adjusted and secured to its support.
Having thus fully described the nature,construction, and operation of my invention, I wish to secure by Letters Patent and claim The herein-described telescopic mounting consisting in combination, a pair of brackets, a case journaled between the same, a spindle j ournaled centrally in said case, a ring loosely surrounding said spindle and having screw threaded ends journaled in the brackets and In testimony whereof I have hereunto set provided with clamping-nuts, a sleeve atmy hand in presence of two subscribing Wittaehed to said spindle and a teleseope-earrynesses. ing shaft journaled in said sleeve and means I 5 for securing said shaft and spindle in their Vitnesses:
adjusted positions, substantially as and for ALBAN ANDREN, the purpose set forth. KARL A. ANDREN.
CARL A. R. LUNDIN.
