This invention relates to themanuiacture of clolleyes. l f 2; 2 2 a 2 The objectsof, the invention center about the assembly of a.,pair of eyes. on .an appropriate cross-rod or eye shaft. t This assembly ismade inexpensive by the use of a key frictionally mounted on the cross-rod at each eye. Provision is made for manual 2 rotative, adjustment of one eye relative to the other, and for an auto: matic self-adjustment of the spacing between the eyes. The eye shells are perforated to receive the cross-rod, and the perforationis made over-sized to permit 2 the desired, free movement of the eye on the shafts- In accordance, with a feature and object of the present invention, the usual separate operation for perforating. the eye shell is eliminated, and the cross-rod is itself used to perforate theeyeshell while. mounting the eye on the .cross-rodw In "accordance with still another feature and object of the invention, the perforation is madeover-sized; although producedby the cross-rod itself, by preliminarily scoring 01" otherwise treating the cross-rod near its ends to produce anupset ring of metal or enlargement on the cross-rod which in. passing through the wall of the eye shell, enlarges the opening thereinto insure a freetfit. f2 2 1 Totheaccomplishment of the foregoing and other objects which will hereinafter appear, my

invention consists in the method of manufacturing a doll eye assembly, as hereinafter more par-' ticularly. described in thespecification and sought eyeset looking in the parser; the line 9 9 of The present. specification deals with the complete eyeset, that is, the assembly of a pair of eyes with a cross-rod and weight foroperating the same. The eye itself is not described in detail, and may be'of any specific character, one

pending fparent application Serial No. 214,189, filed June 17,; 1938, of which the present application .is a division directed particularly to the assembly of the eyes; with a. cross-rod.

The eye assembly is shown inFigs. 7, S and. 9, and comprises the eyes 50 and 52 mounted on the ends of the cross-rod 54 with the aid of keys 56, said cross-rod 54 having welded or otherwise secured thereto, a weight arm 58 carrying at its lower end a weight 60. This consists of a re- -versely bent piece of metal and carries a forwardly projecting piece of cardboard'62 which acts as a bumper strikingthe front wall of the doll head when theeyes move to open position. The upper end of thepweight arm 58 may be extended as indicated at 64 00 form a motionto bedefined inthe claims. The specification is accompanied; by a drawing in which? Fig. 1 shows the cross-rod before it is operated ingthe final stage;

' Fig, Bis a plan view illustratingthefinalstage in the operation of impaling the eyes on the (Fig ails, a' transverse, section through the limiting stop to limit. the, closing movement of the eye, just. as the bumper B2 limits the opening movementof the, eyes. 2 r H The eyes are caused to rotate with cross-rod 54 by means of the keys, 5'6. These arereceived With a tightfrictional fit on the cross-rod and are provided with shoulders 66 which bear against the rear edged the eye shell. The latter is ndtchedor cut away to receive the shoulders 66, as is best shown at tt in Figs. 7 and 9. It is importantthatthe eye be centered with respect to the cross-rod 54,.and while the main rear edge 10 of the eye may vary somewhat in dimension and location, and maybe rough or uneven, the recessed edges 68 at the top and bottom of theeye shell are located exactly in the plane of the center of the eye shell and mate correctly with the shoulders 66 of keys 56. It Will be understood that the keys cause the eyes to turn with the shaft, and that the rotative position of the eyes on the shaft'may be varied by manually turning the eye and key on the'shaft.

This permits adjustment of one eye relative to the other, and permits both eyes to be properly adjusted in the eye openings of the doll head while the weight of the eyeset is moved to its limiting position against the doll head. By means of thisadjustment, the lashes may be caused to rest against the upper edges of the eye openings in the head .when the eyes are open. 7 The: shape of thekeyfifl ismost clearly shown in Fig. 3, in which it will be seen that the hole I therein is open at one side, the hole being formed between separated projections or lugs 92. The benefit of this construction is that the hole may be made initially smaller than the diameter of the cross-rod, so as. to receive the cross-rod with a tight: frictional fit. This is more than adequate to turn the eyes with the cross-rod, yet the eyes together with the keys may be manually rotatively adjusted on the cross-rod to best fit the eye openings of the particular head in which the. eyeset is being installed.

It has been mentioned that the shoulders 66 are located in the plane of the axis of the crossrod or the hole I00, but it will be understood that it is not necessary for the shoulders to be located directly in the plane of the axis, it being sufiicient if it is located in some fixed desired relation to the plane of the axis. In such case, the notches orrecesses 68-of the eye shells should be correspondingly changed, so as to have-the same fixed desired relation to the center of the eye shell, in order to properly mate with the shoulder's66.

In the present construction, the perforations through the side wall of the eye for receiving the cross-rod 54 are made over-sized to insure a loose -fit of the eye on the cross-rod. Moreover, the notches 68 are made substantial in side to side dimension, as is clearly shown in Fig. 7. This permits a limited sidewardmovement of the eyes on the cross-rod, the limit of motion being deterthe keys 56, which are made somewhat closer than the maximum dimension from top to bottom in the eye. In this way an automatic adjustment of the distance betweeneyes will take place so that the eyes will accommodate themselves to the eye openings in the doll head.

This is illustrated in Fig. 7 of the drawing, in which the solid line position of the eyes indicates the approximate mid-position or normal position of the same; The eyes may move outwardly relative to the mid-position, this being shown by the dot-and-dash outline in *the lefthand part of Fig. 7. The eyes may also move inwardly relative to the mid-position, this being shown by the dot-and-dash outline in the right-' hand part of Fig. 7. -If the spacing between the eye openings of the doll head is less than usual, the eyes may move inwardly to fit the eye openings, and conversely, if the spacing between the eye openings is greater than usual, the eyes may move outwardly to accommodate the increased spacing.

In accordance with the present invention, the openings in the inner'walls I4 of the eyes are made by the cross-rod 54. With'this object in View, the ends of the cross-rod are preferably pointed, as shown at 16. A short distance in from the ends, the cross-rod is so treated as to form an enlargement or raised ring of metal therearound. In the present case this is done by simply scoring the cross-rod inwardly at 18, thereby displacing some metal outwardly at each side of the scoring 18. This scoring is located between the key 56 and the wall 14 of the eye, so that in forcing the cross-rodthrough eye, the enlargement is also forced through the wall of the eye, thus making the opening in the eye large enough to insure a free fit of the eye on the crossrod.

The. manner in which the cross-rod is pointed and scored, is schematically illustrated in Figs. 1

and 2. The cross-rod, is initially a piece of plain round wire with sheared ends, as is indicated at I02 in Fig. 1. This may be gripped at the center between jaws I04 (Fig. 2) and the ends pointed by cutters I06. These cutters may rotate, and also revolve about the axis of rod 54, thus pointing the ends, as indicated at I6.

The ridges on the cross-rod may be formed by wheels I08 carried on bearings IIO which are mounted to revolve about the axis of the crossrod. These bearings may also be moved toward or away from the cross-rod, as well as axially of the same. When moved toward the cross-rod, they indent the same and excise some of the metal outwardly, which effect may be increased by a slight axial movement.

In practice, the rod may be pointed and grooved in a single operation, the wheels I06 and I 08 all being carried by rotating heads which are arranged to move axially of the cross-rod. The heads are moved apart to permit the blank rod to be placed therebetween, and the heads are then moved axially toward one another in order. to point the ends. After the heads-have moved inwardly over the ends of the cross-rod, the wheels I08 are moved radially inwardly-to form the desired grooves and ridges.

The weight arm 58 with its weight 60 is next secured to the cross-rod, this attachment preferably being efiected by spot-welding the wires together.

The manner in which the eyes are assembled on the cross-rod may be explained with reference to Figs. 4 through 8. A suitable fixture or tool is provided having a support for receiving the cross-rod 54 and weight arm 58 and anchoring these against movement. The tool includes slides 82 which are movable toward or away from the support 80. In Fig. 8-they are shown in inward position, but at the. beginning or the assembly operation, the slides 82 are to be assumed tobe in their outward position beyond the ends of the cross-rod 54, as shown in Fig. 4. Each slide has formed thereon a supporting projection 84 which is shaped to receive the eye member therearound.

Generally speaking, the projection 84 is-spherically surfaced .to receive the eye shell, but the top is cut away or flattened somewhatin order to provide ample clearance for the indented iris portion and the eyelash foundation, etc. The projection 84 is slotted in one direction at 86 to receive the key 56. It is slotted in the other direction at 88 to receive the cross-rod. It is'provided with ledges or steps at 90 to receive the notches or recesses 68 of the eye shell.- These support and locate the eye shell in proper position relative to the axis of the cross-rod.

In practice, a cross-rod and weight arm assembly is placed on support 80, keys 156 are placed in slots 86, and eyes are placed over the. supports 84. The slides 82. are then moved to-v gether, thus forcing the ends of the cross-rods through the walls of the eye shells, andfurther driving the ends of the cross-rod into the keys 56. The keys have previously been stamped to the configuration shown in Figs. 3 and 9, and are provided with a hole for receiving the crossrod. This hole is preferably slotted at one side and is formed between the lugs 92 shown in Figs. 3 and 9, thereby providing a resilient frictional grip .on the. cross-rod. The assembled eye set is then lifted from the tool and is ready for use.

The method of assembly may be described in greater detail with reference to Figs. 4 through grooms oif'the cross-rodand weight arm assembly by the support 80 is shown in the center portion of Fig.4. At-this time the slides 82 are spread apart far enough to receive the cross-rod therebetween. K

Theslides 82 are then forcibly moved together by appropriate mechanism, not shown in the drawing. The initial penetration of the crossrod through the inner wall 14 of the eye is clearly shown in Fig. 5. At this time, the hole formed in the eye fits the cross-rod tightly. ,The final position of the cross-rod is shown in Fig. 6, and it will be noticed that at this time the crossrod has been pushed through the key 56, and that the enlargement N2 of the cross-rod has passed through the inner wall of the eye, and has enlarged the hole formed in the eye, so that there is an appreciable clearance between the hole and the cross-rod.

This final position of the cross-rod is also shown in Fig. 8, in which the slides 82 have moved toward one another to an inward position which is to be contrasted with the separated or outward position shown in Fig. 4.

' It is believed that the construction of my improved eyeset, as well as the method of manufacturing and assembling the parts thereof, will be apparent from the foregoing detailed description thereof. sheet metal which is easily drawn to the desired hemispherical or cup-shape, and which is readily punched by the cross-rod during the subsequent assembly operation.

Despite the simple and inexpensive character of the present eyeset, it nevertheless makes possible the desirable eye adjustments, including a manual rotative adjustment and an automatic axial adjustment of the eyes.

It will be apparent that while I have shown and described my invention in a preferred form, many changes and modifications may be made without departing from the spirit of the invention as sought to be defined in the following claims.
