GOGGLES Filed Nov. 25, 1929 Patented Dec. 9, 1930 PATENT OFFICE ROBERT MALCOM, F CHICAGO, ILLINOIS GOGGLES Application led November 25, 1929. Serial No. 409,468.

My invention Vrelates more particularly to goggles involving eye-cups adapted to substantially inclose the eye cavities; the two eye cups being preferably loosely connected or linked together, while any suitable hea-dgearing or strap is employed for securing the goggle in place.

The invention has for its object the provision of eye cups composed of comparatively thin sheet opaque material, preferably sheet metal, adapted to removably hold the lenses securely in place, so. that renewal of the lenses, when broken, or lenses of a different character, may be readily made by the user without need of special tools or devices.

The objects and advantages of m invention will be readily comprehended rom the following detailed description of the accompanying drawing, wherein Figure 1 is a face view of one of the eyecups, with only a portion of the eye-cup connecting chain and a portion of the attaching strap being shown.

Figure 2 is a horizontal cross section taken substantiall on the line 22 of Figure 1.

Figure 3 1s a vertical sectional view taken substantially on the'line 3 3 of Figure 1, viewed in the direction of the arrows.

Figure 4 is a view similar to Figure 3,

showing the eye-cup in opened or spread condition.

Figure 5 is an end elevation of an eye-cup as viewed from the left in Figure 1.

Figure 6 is a similar view, illustrating the eye-cup in open or spread condition.

Figure 7 is a detail sectional view, taken substantially on the line 7-7 of Figure 5, as viewed by the arrows.

My improved goggle, which is intended to prevent dirt and particles of material from entering the eyes, as well as to exclude objectionable side light, comprises a pair of eyecups which are identical in construction so that description of one eye-cup will suilice.

The eye-cups are each made of sheet metal cut to proper size and shape so as to permit being folded into substantially circular form, as shown in Figure 1.

The blanks are cut to fit about an eyesocket, having a short side wall 10, adapted to fit the eye-socket adjacent to the nose, and perovided with some suitable connecting memr or nose bridging element, preferably in the form of a loose oryfelding chain, of which a portion is shown at 11, for yieldingly connecting the two eye-cups of the gogg e. v

The/blank is cut to somewhat meet the curvature of the face adjacent to the eye and to provide the wide side wall 12 which is disposed adjacent the temple of the wearer.

The blank is folded to provide a split cup with the opposite edges of the blank. normally brought into abutting relation, as shown at 13 in Figure 3.

In cutting the blank complementary portions are produced at the ends; that is one end is provided with a slot 14, see `Figure 4, while the other end is provided with a correspondingly shaped tongue 15 which normally lits into and fills the slot 14, as shown in Figure 3.

The outer marginal edge is formed to provide a groove 16 to receive the perimeter of the lens 17 the diameter of the groove when the cup is in normal condition being such that the lens will be firmly held in lace.

In order to hold the abutting edges 13 in proper relation and therefore maintain the split eye-cup in normal lens clamping condition, I provide a holding and controlling element which is shown in the nature of a combined locking and head-strap attaching plate 18.

The member 1:8, of sheet metal, is of suitable width to lap or extend beyond the abutting ends 13 o the encircling band or cup and is disposed transversely of the band or Acup as shown in F igure.

The member 18 is shown provided with a number of diagonally arranged or slopin slots 19, all preferably of the same lengt/ or configuration shown more clearly in Figure 5. These slots are arran ed in pairs on opposite sides of the longitudinal axis of the member 18 as shown. Each end 13 of the eyecup wall is provided with a pair of small outward projections preferably in the form of small eyelets 20 which are inserted through wall 12 and through the slots 19 of the con- 110.

trolling member 18; the outer outwardly uplarger diameter than the width of the slots 19, so that the plate or controlling member 18 will be properly held in place.

The slots 19 slope downwardlyand outwardly from the upper ends which are disposed toward the lens-holding perimeter of the cup. With the slots 19 slightly wider than the diameter of the intermediate body portion of the eyelets, it is apparent that the controlling element or member 18 m'ay be moved transversely of the eye-cup wall so as to present opposite ends of the slots 19 to the eyelets Q0. As the slots slope toward the opposite sides of the member 18 and therefore farther away from the plane of the meeting edges 13 of the eye-cup wall, it is apparent that movement of the member 18 transversely of the eye-cup will induce the meeting edges 13 of the cup to be spread apart or brought together depending upon the direction of movement of member 18.

That is to say, with the member 18 positioned as shown in Figure 5 where the eyelets are located at what may be termed the upper ends of the slots 19, the eye cup will be completely contracted in closed lens-holding condition, as shown in Figure 3. Upon shifting or moving the member 18 transversely of the cup in a direction toward the lensholding rim, the eyelets will ride lengthwise of the slots 19 toward the outwardly disposed ends 19a. It is apparent that the meeting ends 13 of the cup wall will be spread apart in the manner disclosed in Figures 4 and 6. In this spread apart or opened out condition, the lens 17 will be released, as shown in Figure 4, thus permitting easy insertion or replacement of the lens, which may then be clamped in place by simply moving member 18 in the opposite direction so as to position the eyelets in the slots, as shown in Figure 5.

The tongue '15 and slot 14 are preferably of such length that the tongue will partially extend into the slot when the cup wall is in its fullest distended or opened out condition, as shown in Figure 4, so as to ensure proper alignment of the abutting ends 13 being maintained.

The lower `end of plate or member 18, namely the end disposed away from the lens holding rim of the cup, is shown bent slightly outward at 21, Figure 2; and this outwardly bent end, which is of comparative width, is transversely slotted for attaching the end of the headear or strap thereto; a portion of the strap ing shown at 22.

With the head-strap secured to the end 21 of member 18 it is ap arent that pulling strains on the strap will exerted in proper direction on member 18 to maintain the eyelets at the up er converging ends of the slots so that the ens will be firmly clamped in place. The upper end of member 18 is bent slightly outward so as to ride over the lensholding rim 16 of the eye cup.

By curving the diverged ends of the slots toward one side of the longitudinal axes of the slots, a complete spread of the eye-cup walls is induced while at the same time accidental movement of the member 18 through the contracting force of the eye-cup walls will be prevented until the member 18 is manually shifted in the right direction. The member 1,8, as shown, provides head-gear attaching means and means whereby positive movement of the eye-cup walls is induced.

I have'lshown the member 18 provided with ai number of slots on each side of the longitudinal center of the member and the walls of the eye-cup provided with an equal number of eyelets, but it is apparent that the number of slots and eyelets may be changed and that the slot-engaging elements need not be in the nature of the eyelets shown; such changes being possible without, however, departing from the spirit of my invention.

What I claim is 1. In a goggle, an eye-cup having a side wall of sheetI material formed to bring the ends of the sheet into adjacent relation, while one of the edges of the sheet is formed to provide a lens-holding groove; a plate disposed transversely of the eye-cup in lapping relation with the adjacent ends of the cup-Wall, said plate being yprovided with diverging slots; and protruding portions on the cupwall disposed through said slots whereby the position of said plate controls the relation of the adjacent ends of the cup-wall.

2. In a goggle, an eye-cup formed of sheet material bowed into a lens-holding frame, the juxata osed ends having matching portions to malntain alignment of said ends; the frame adjacent to said ends having protruding portions; and frame clamping means slidable transversely of the frame and provided with diverging slots adapted to receive said, portions, whereby movement of, said means in one direction causes the frame ends to spread apart while movement of said means 'in the opposite direction causes said frame ends to move into juxtapositon.

3. In a goggle, eye-cups formed of sheet material bowed into lens-holding frames with the ends of the sheet in juxtaposition; said ends having a matching tongue and slot for maintaining proper alignment of said ends; said frame adjacent to the ends being provided with protruding eyelets; and a slotted member adapted to have the eyelets extend through said slots, said slots diverging toward opposite sides of the member so that movement of the member in one direction causes the frame ends to move toward each other while movement of the member in the opposite direction causes the frame ends to move away from each other.

l. ln a goggle, an eye-cup formed of sheet material formed into a lens-encircling frame, the frame adjacei "1 to itsl ends` being provided with outwardly protruding elements; and a divergingly slotted plate slidably held in place by said elements` extendinzgr through the slots` whereby movement of said plate causes said frame to expand or to contract. said plate havinger an outwardly disposed slotted end for attaclnnent of a head encirclingstrap.

5. In a goggle, an eye-cup formed of sheet material bowed into a lens-encircling frame adapted to fit about the eyes ofthe wearer, the juxtaposed ends of the frame-sheet being provided with correlated portions Jor maintainingr alignment of said ends;v a plate disposed transversely of the juxtaposed ends of the frame so as to lap the joint, said plate beiner adapted to slide in directions toward and away from the lens-holding edge of the frame, with its end adjacent to the face-engaging end of the frame provided with a head strap 'fastening portion and means associated with said plate and the frame whereby a movement of the plate causes the frame to expand or contract for releasing or clalnping a lens in the frame.

G. In a goggle, an eye-cup made of resilient material formed into cylindrical shape with the ends in opposing relation; a member arran'fed to lap the ends of the cup wall; and sloiand pin connections between both ends of the cup-wall and the member adapted to permit the member to bodily slide transversely of the eye-cup, the slots of said connections beiner so formed that sliding the member in one direction induces a spreading of the ends while sliding the member inthe opposite direction causes said ends to be brought toward each other.
