Improvements relating to Telescopes and the like, and Coin Receiving
Operative Mechanism in connection therewith.
I, GUSTAV SCHMIDT of Ebersbach in Saxony, in the Empire of Germany,
Manufacturer do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :—
A
This invention relates to a telescope or the like with shutter mechanism of such
nature that on throwing a certain coin into a slot of the apparatus the weight of this
coin moves a plate which lay before the glasses closing the view and keeps this plate
in such position for some minutes that the telescope may be open for vision.
clock-work, which is put into operation by throwing in the coin, brings the plate back
again before the glasses aud covers the sight until the mechanism is again disengaged
by putting in another coin.
An orientation table is fitted for the purpose of permitting the telescope to be
swung in the horizontal plane, the upper part of the apparatus being pivoted. By
turning a hand-wheel the glasses are adjustable in height for taller and shorter
persons.
In the annexed drawing
Fig. 1 is a front-view in section and
Fig. 2 is a side-view in section of the casing and mechanism therein.
Fig. 3 is a plan.
Fig. 4 shows one position of part of the mechanism.
Fig. 5 shows the apparatus on its pedestal with orientation table.
Figs. 6 & 7 are separate parts thereof.
To the front-wall of a casing a are fixed binocular glasses b, which by turning the
button c can be adjusted for any sight, by the toothed wheel d gearing with the
toothed rack e. On the front wall is also the slot for the coins. The coin rolls
through guides f, g on to the plate h of the mechanism which stops or disengages the
driving mechanism and moves by its weight the plate, which closes the glasses, so that
the view is opened. For this purpose the back-wall of the casing is partly formed of
an optically true glass-plate. The driving mechanism and the mechanism for stopping
and disengaging the former are constructed in the following manner. Between two
plates screwed on the bottom of the casing there is provided a spring-barrel b,
the toothed crown of which engages the pinion m of the shaft n, whereby the
toothed wheel o is revolved. Between these plates kk' is also journalled (as shown in
Figs. 1 & 2) the anchor & as well as its regulating mechanism, which consists of a
balance spring t with fly-wheel u. On the front-plate k is a lever v, which has two
noses vvv has a pin ³ which reaches through a hole 2 of the plate / and which
serves as abutment for a pin 1 of the wheel r, so that, when the wheel has turned so
far, that the pin abuts on the pin 3 of the part v¹, the driving mechanism is
stopped. In order to maintain the lever in the position shown in Fig. 1, in which
the driving mechanism is stationary, there is provided a lever w, which is fixed on the
end of a shaft w' and lies against a pin x. In the middle of the shaft is also fixed the
lever w² carrying the plate h, and also as counter-weight for the same a lever w³ with

page_text: a weight w displaceable on screw-threads. By displacing the weight w on the
lever w³ it is possible, to adjust the mechanism disengaging the driving mechanism
exactly corresponding to the weight of the desired coin.
On the shaft n outside the plates kk' is a disk n¹ with two pins, which turns in the
direction of the arrow when the mechanism is going. The lever v is in connection
with the plate which lies before the glasses and turns in arms i'. By means of the
coin, which falls on the plate h, and by the lever w' the shaft w¹ and with the latter
the lever w are turned by overcoming the weight w; the part slides from the
lever wand the lever takes the position shown in Fig. 4. Thus by the falling down
of the plate (shown in Fig. 2 in dotted lines) the view through the glasses b is opened.
Of course the plate may also be turned upwards or sidewards according to its arrange-
ment. The pin of the part v sinks with the same and with the lever v and allows
the driving mechanism to operate by coming out of reach of the pin 1. During the
operation also the disk n¹ turns half as quickly as the pin-wheel; by means of the
pins n', which push on the lever part v', the lever vis again lifted, the plate i is
brought before the glasses and the mechanism stops in consequence of the pin 1 of
the toothed wheel abutting on the pin v3. After the coin has fallen down and the
lever with the part v2 is lifted by the disk n, the lever is pressed by the counter-
weight against the pin x, so that the lever v rests again on the lever w, whilst
a slight further revolution of the disk n brings the same out of reach of the
nose v¹.
A partition y divides off a money-chamber, in order that the coins may not fall
amongst the works. In the upper parts of the sides of the casing are arranged
hooks z which serve for closing the cover. Fig. 5 is a view of such an automatic
telescope with orientation table and adjusting device.
A is the apparatus with the glasses; B is the orientation table (Fig. 6) which is
screwed on the pedestal. C is an indicator, which is connected firmly with the
screw-spindle D by the square prolongation of the same, so that when turning the
apparatus A the indicator is also turned, so that the observer can study the surroundings
by means of the orientation-table. By turning the hand-wheel F (Fig. 7) the apparatus
may be lowered or raised and is therefore applicable for the use of tall and short
persons.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is ―
1. A telescope or the like fitted with mechanism for obstructing the view until the
receipt of a coin in the apparatus in the casing a adjustable in its height by turning
a hand-wheel F the glasses b being adjusted by means of a projecting button c.
2. The combination with a telescope or the like of the driving mechanism and the
double-lever w² w3 stopping and disengaging the latter, this lever, when falling,
turning a lever w, which frees the lever with the plate i and uncovers the glasses by
the automatic removal of said plate, and frees the driving-mechanism, which has been
stopped by a pin 1 of a driving-wheel r, said pin standing against a pin 3 of the
part of the lever v; the lever v with the plate i being again lifted by the driving
inechanism turning a disk n', the pins of which push against the part and lift the
lever v, which is again supported by the lever w.
3. The construction of said telescope or the like and its mechanism substantially as
illustrated and described.
