It has been realized that anti-glare or polarized spectacles as used for example by air-crews, mariners and observation personnel and such like persons, are not entirely satisfactory. Although they shade the eyes from direct rays of light they do not divert the scattered rays coming from other directions. In practice it is found such spectacles diminish visual acuity, and cause momentary upset in accommodation when they are removed.
The object of this invention is to provide a device which will place the eyes in complete shade; will at the same time give normal or increased visual acuity; will remove rays reflected from cloud banks and water surfaces; will remove scattered lateral rays; and will be light, comfortable and easily maintained in position on the wearer. A further object is to provide a device which will protect the eyes of industrial workers, for example workers engaged in grinding and similar processes associated with high speed wheels and the like, furnace attendants and men employed in all smelting operations. Cther objects will be apparent from the following description.
The invention will be fully understood from the following description taken in connection with the accompanying drawings wherein:
Figures 1 and 2 are respectively rear elevation and plan of the invention adapted for observatlon purposes;
Figure 3 is a section on the line A-A of Figure 1;
Figures 4 and 5 are respectively rear elevation and plan of a modified form of the invention adapted for use by industrial workers;
Figure 6 is a section on the line B--B of Figure 5;
inFigure '7 is an elevation of the lens retaining 8';
Figures 8 and 9 are respectively front elevation and plan of a further modified form of the invention adapted for use by the public;
Figure 10 is an enlarged fragmentary rear elevation of Figure 8 showing the bridge;
Figure 11 is a section on the line C-C of Figure 10; and
Figure 12 is a section on the line D-D of Figure 8.
Referring to Figures 1 to 3 a shell I, of tinted (preferably green) Celluloid or material of a similar character, is moulded or otherwise formed to have somewhat semicircular horizontal and centre vertical cross sections. Glass or a similar material may be used to form said shell I but is undesirable due to its tendency to shatter when conform to the normal contour of the forehead, temples, bridge of the nose and cheeks, whilst a V-shaped recess 3 is provided in the lower rim 2 to fit over the nose. Preferably a piece of split rubber tube 4, or the like, is glued around said recess 3 to form a comfortable dustproof rest over the nose. Two tear shaped apertures 5, in line across with their thinner ends merging at the centre, are provided in the bulge of said shell I directly in front of the wearers eyes. Wires 6, preferably flexible, areprovided at the ends of said shell I and are secured-to rim 2 by rivets I. Said wiresfi are shaped to hook over the ears of the wearer and thus maintain shell I in th correct attitude.
Although the invention is primarily adapted for use without spectacles, the bulged shell will accommodate spectacles if necessary. It is not generally intended that there shall be glass or other transparent windows in the apertures, but such could be provided if required for special purposes. For example the inventionmay be usefully employed during the treatment of ophthalmia where glare is to be avoided, Where children are being treated it may be found very desirable to incorporate windows to prevent ingress of flies likely to gather and distribute infection. In a modification flat sections may be provided which are clear or faintly tinted in the bulged shell in front of the eyes, such sections being formed during the moulding of the said shell.
Tests carried out with shades made according to this invention have shown that,
(a) The shades give full visual acuity, there being no limitation in the acuity of direct vision. The fields of vision are diminished slightly by the material used, but this is only comparable to the diminution of acuity evident in Polaroid spectacles.
(b) Direct vision is increased in acuity. The shade actually acts as a stenopoeic lens, and the normal visual acuity of 6/9 is increased to 6/6.
(c) The eyes are in complete shade. Tests carried out show the eyes in ordinary glare experience foot candles, whilst with the shade attached, they experience 12 foot candles.
(d) Those rays which are reflected from the surface of the water, ground, cloud or the like are prevented from being directed to the eyes by the lower surface of the shade.
(e) The scattered rays from lateral, medial and upper directions are prevented from entering the eyes by the surrounding close-fitting surfaces of the shade in those positions.
2 Y knocked. The rim 2 of said shell is shaped t The invention may be applied as a peak of a cap or the like or an integral part of other headwear used by persons requiring protection from glare.
In a modified form (as suitable for industrial purposes) in lieu of apertures 5, two circular, outwardly flanged openings 8 are provided in the bulge of said shell I (see Figures 4 to 6). Said openings "8 are located directly in: Ffront of :the wearers-eyes; and, around theiroutsides, are'provided with a groove 9 adapted to locate a split spring, clip ring ID (see Figure 7). Said ring W has a series of right angled lugs I I whicnfirmly grip and locate a disc I2 of tinted or clear glass over opening 8.
In this form the invention is adapted particu- 1.
larly for use by industrial workerswhose .eyes require protection from furnace glare :andfhea't, and from hot flying particles from grinding wheels and the like. When discs I2 haveebeco-me marked by flying particlesfand the like new discs can speedily be substituted by 7 means of ringslfl.

Die Erfindung betrifft eine Friktions-Presse, die so aufgebaut ist, daß am oberen Ende einer Gewindestange, die einen
Stößel an ihrem unteren Ende aufweist zwei Antriebsräder befestigt sind, die in Vertikalrichtung einen Abstand voneinander
aufweisen, daß zwei Antriebsscheiben an beiden Seiten der Antriebsräder vorgesehen sind, die sich zueinander entgegengesetzt
drehen, daß die oberen Teile der inneren Reibung soberflachen der Scheiben und die unteren Teile der inneren
Reibungsoberflächen derselben Scheiben abwechselnd mit
den Reibungsumfängen des oberen Antriebsrades und des unteren
Antriebsrades in Reibberührung sind, wodurch sich die Gewindestange abwechseln in eine Richtung oder in die entgegengesetzte
Richtung dreht und damit auf- und abgeht, wodurch der Stößel zum Auf- und Abgehen gebracht wird. The invention relates to a friction press which is constructed so that at the upper end of a threaded rod, the one

rotate so that the upper parts of the inner friction soflatten the discs and the lower parts of the inner
Friction surfaces of the same disks alternate with
the amounts of friction of the upper drive wheel and the lower
Drive wheel are in frictional contact, causing the threaded rod to alternate in one direction or in the opposite direction
Direction rotates and thus goes up and down, causing the plunger to go up and down.
Herkömmliche Eeibungspressen sind so aufgebaut, daß ein Antriebsrad
an einer mit einem Stößel an ihrer unteren Ende versehenen Gewindestange befestigt ist und mit dem unteren
bis mittleren Teil von zwei Antriebsscheiben in Berührung kommt, die an derselben Tragewelle an beiden Seiten des Antriebsrades
vorgesehen sind und die sich in derselben Richtung drehen, daß die Tragewelle der Antriebsräder in der einen
oder in der anderen Richtung alternativ bewegt wird, wodurch das Antriebsrad so in einer Richtung angetrieben wird, daß es
nach oben oder nach unten geht und auf diese Weise der Stößel nach oben oder unten gelassen wird. Ein solcher Aufbau hat
die Nachteile, daß die Energie der Antriebsscheiben nicht zufriedenstellend auf das Antriebsrad überführt wird, da nur
ein Punkt vorhanden ist, an dem eine Berührung und eine Reibbeziehung zwischen dem Umfang des Antriebsrades und der inneren
Oberfläche der Antriebsscheibe stattfindet, daß an der Stelle, an der die Gewindestange gelagert wird, die nach oben
und nach unten geht, eine Störung an der Berührungsstelle zwischen dem Umfang der Gewindestange und dem sie haltenden
Teil auftritt, wodurch das Drehen und die Auf- und Abbewegung der Gewindestange verlangsamt wird, was die Wirksamkeit der
von der Presse ausgeführten Arbeit herabmindert. Conventional friction presses are constructed so that a drive wheel
is attached to a threaded rod provided with a plunger at its lower end and to the lower one
to the middle part of two drive pulleys comes into contact, which on the same support shaft on both sides of the drive wheel
are provided and which rotate in the same direction that the support shaft of the drive wheels in the one
or is alternately moved in the other direction, whereby the drive wheel is driven in one direction that it
goes up or down and in this way the plunger is left up or down. Such a structure has
the disadvantages that the energy of the drive pulleys is not satisfactorily transferred to the drive wheel, since only
there is a point of contact and frictional relationship between the periphery of the drive wheel and the inner one
Surface of the drive pulley takes place that at the point where the threaded rod is stored, the upward
and goes down, a disturbance at the point of contact between the circumference of the threaded rod and the one holding it
Part occurs, which slows the turning and the up and down movement of the threaded rod, which increases the effectiveness of the
degrades the work done by the press.
Anstattdessen sieht die Erfindung vor, daß an zwei Stellen Berührung und Reibkontakt zwischen dem Umfang des Antriebsrades
und der Innenfläche der Antriebsscheiben stattfindet und daß dazuhin die Gewindestange immer störungsfrei in der
Mitte des Halteteiles gehalten werden kann und sich störungsfrei auf und ab dreht. Es ist demzufolge möglich, den Reibungswiderstand
herabzumindern, wenn sich die Gewindestange dreht und auf und ab geht, und damit die Bewegung der Gewindestange Instead, the invention provides that contact and frictional contact between the circumference of the drive wheel at two points
and the inner surface of the drive pulleys takes place and that in addition the threaded rod is always trouble-free in the
Can be held in the middle of the holding part and rotates up and down without interference. It is therefore possible to reduce the frictional resistance
to decrease when the threaded rod rotates and goes up and down, and with it the movement of the threaded rod
