MOUNTENG i-QR RANGE=F!NDER$.
SPECEFICATION forming part of Letters Patent No. 710,787, dated October '7, 1902.
Application filed October 14, 1901. Serial No. 78,634. (No model.)
To (11 whorlt it may concern:
Be it known that we, ARCHIBALD BARR, professor of engineering in the Uni\ ersity of Glasgow, in the city of Glasgow, Scotland,and
\VILLIAM STROUD, professor of physicsin the Yorkshire College, Leeds, England, subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements in Mountings for Range-Finders, of
to which the following is a specification.
Our invention relates to mountings for range-finders of the type shown in patents previously granted to us-for example, see Patent No. 5S3,243,dated May 25, 1897; and
15 it has for its object to provide an improved construction adapted to be used on board ship.
The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and pointed out in the appended claims.
Reference is to be had to the accompanying drawings, in which Figure 1 is a rear elevation, partly in sec- :5 tion, of our improved mounting; and Fig. 2
is a side elevation.
A range-finder A of the type shown in our previous patents above referred to is carried by a bracket B, provided with a central open- 0 ing and capable of rotating on the vertical spindle Ii. Forks or bearings C C are provided on said bracket, in which the instrument may be rotated about a horizontal axis, and to facilitate this latter rotation the forks C C may be provided with rollers D D or equivalent device for reducing friction. By means of a handle E, which may be made to bear against a guide F on the bracket IS, the motion may be controlled in accordance with the rolling or pitching of the ship. A breastpiece G, on which the observer leans to control the rotation of the instrument about the vertical spindle L, is connected to the bracket 13, and when the instrument is not in use it 5 maybe folded up into the central opening of said bracket B, as shown in Fig. 1 and in section and dotted in Fig. 2.
To adjust the height of the instrument from the deck, the bracket B is mounted on the sleeve H, which slides in the pedestal, and
the sleeve is held against any rotary movement by means of a projection 1 upon the interior of the pedestal, which works in a vertical groove Q in the sleeve H and may be raised or lowered by rotating ahand-wheel K, operating the screw L, which works in the internally-threaded sleeve M.
A stop 0, thrown in or out of notches in the collar on the top of the sleeve by the thumb of the observer, serves to lock the bracket 13 in one of a number of positions.
Having thus described our invention, what we claim is- 1. In a mounting for range-finders,the combination of a rotatable bracket, a range-finder mounted on the bracket, and a breast-piece by means of which the operator moves the range-finder about its vertical axis.
2. In a mounting for range-finders,the combination of a rotatable bracket, having an opening therein, a range-tinder mounted on the bracket, and a breast-piece, by means of which the operator moves the range-finder about its vertical axis, foldable into the opening of the bracket.
in a mounting for range-finders,tl1e combination of a pedestal, a sleeve adapted to slide therein, a bracket mounted on said sleeve, a spindle, about which the bracket is adapted to rotate, a screw adapted to raise $0 and lower the sleeve, and a range-finder r0- tatable about a horizontal axis upon said bracket. 7
t. The combination of the pedestal, the sleeve II adapted to slide therein, the bracket B having a central opening, mounted on the sleeve, the spindle K aboutwhich the bracket 13 is adapted to rotate, the breast-piece G for moving the bracket around its vertical axis, foldable into the central opening of the bracket I3, and the bearings 0,0, adapted to receive a range-finder.
5. In a mounting for range-finders,the combination of a range-finder, of means permitting said range-finder to rotate upon its ver- 5 tical axis, means permitting it to rotate upon its horizontal axis, and means for raising and lowering the bracket carrying the rangefinder.
In testimony whereof we aflix our signa- 10o tures inpresence of two witnesses.
