1,065,192. Specification of Letters Patent.

Application filed January 16,

form severally adapted to interlock with a seat on the cap. \Ve have shown as a pre ferred form of catch one formed by slitoutwardly To all whom it may concern Be 1t. known that we, Aoeus'r nnnn, Sn, and JOHN WEBER, each a citizen of the United States, residing at Schenectady, ting the shell transversely, and

county of Schenectady, and State of New dlsplaclng a portion of the body of the shell York, have invented certain new and useat the upper side of said slit, thereby formful improvements in Cases for Incandes ing' a downwardly and outwardly inclined catch with a cut-metal edge. One of the catches, 4, is preferably located adjacent to the slot, 2, for convenience in releasingthe catch by compression of the shell, if desired. The cap, 3, which is also preferably formed of sheet-metal, is adapted to telescopically receive within its lower end the upper end of cent-Electric-Lamp Sockets, of which the following is a specification.

The invention relates to such improve ments and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein. Figure l of the drawings is a view in side elevation of a case for incandescent electric lamp-sockets embodying our invention. Fig. 2 is a bottom plan view of the cap removed. Fig. 3 is a central, vertical section of the same, taken on the broken line 3-3 in Fig. 1. Fig. 4 is a top plan view of the shellmember of the case. Fig. 5 is a vertical crosssection of a portion of the case, showing the interlocking,mechanism for preventtelescopic movement of separation'of one member from the other.

The several figures are drawn on an enlarged scale.

The principal object of the invention is to facilitate the assembling of the cap an shell-members of the case, while preventing relative rotation of said members when apthe shell, and'is preferably provided with a continuous seat, 5, extending around its inner periphery adapted to receive and interlock with the several catches, 4, in any relative rotative position of the shell and cap. The seat, 5, is formed by a ledge or offset, 6, formed by bending an annular portion of the body of the cap into a plane perpe' .dicular to the axis of the cap, making the lower end of the cap substantially Z-shaped in cross-section, said ledge, 6, being adapted to be engaged by the cut-metal edges of the catches, 4;, to lock the cap and shell together to prevent a relative movement of separation thereof. The lower end or flange, 7, of the cap is adapted to ride over the inclined surfaces of the catches, t, until the ledge, 6, reaches the lower end of the respective catches, whereu )011 the parts interlock with a snap-action. Tie cap and shell can thus be assembled or applied to one another by a simple telescopic movement in any As a means for preventing a relative rotative movement between the cap. and shell when applied toea-ch other and interlocked. while permitting said cap and shell to'be so applied to each other and interlocked in any one of many relative rotative positions, the edge of the cap-flange, 7 is serrated to form thereon a plurality of wedge-shaped teeth, 8, as shown in Figs. 1 and 2-, while the shell is provided with a seat or pocket, 9, adapted to receive one of the teeth, 8, when the cap and shell are assembled. in any one of the numerous relative rotative positions in which they are designed to be used. The seat or pocket, 9, is preferably formed by transversely slitting the body of the shell, and outwardly displacing a'portion JOSilSiOD and interlocked.

Other objects of the invention will appear in connection with the following description.

Referring to the drawings, wherein is shown a preferred form of the invention, 1, is the shell of the socket, preferably formed of sheet-metal, and preferably provided with a slot, 2, which in a key-socket may be 0 a width adapted to receive the shaft of the switclrkey, not shown.

The shell is provided near its upper end with a plurality of catches, 4, preferably symmetrically disposed about the periphery of the shell, and projecting outwardly therefrom. For certain purposes-of the invention these catches may be of any desired relative rotative POSlt-IOII.

thereof on the inner side oi said slit, as shown, The number and order or arrangement of the teeth, 8, on the cap-flange may be varied as desired, but we prefer to continue the serrations symmetrically entirely around the cap, in'which case asingle seat or pocket, 9, adapted to receive and closely fit one of said teeth, will be suiiicient to prevent a relative rotative movement between the case-members in any relative rotative position in which the parts may be assembled and interlocked; although we do not wish to be limited to a single seat or pocket, 9, nor to any specific form for the same, as, for certain purposes of the in-' vention, the shelllmay be provided with any known means for interengaging with the teeth on the cap to prevent relative rotation between the cap and shell when interlocked, and with any desired number of such means. I

In the preferred form of our invention shown, the ofiset or shoulders, 6, projects outwardly beyond and overhangs the serrated edge-flange, 7, and protects the teeth, 8, thereon.

What we. claim as new and desire to secure by Letters Patent is V 1. In a device of the class described, and

in combination, a sheet-metal cap having a serrated end-flange; and a sheet-metal shell adapted to be telescopically received within said flange, and having means adapted to engage the serrated edge thereof.

2. In a device of the class described,and in combination, a sheet-metal cap having a serrated end-flange; and a sheet-metal shell adapted to be telescopically received within said flange, and having means adapted to engage the serrated edge thereof, said shell and cap being automatically interlockable when telescopically applied one to the other.

3. In a device of the class described, and in combination, a pair of tubular sheetmetal members, one adapted to telescopically receive the other, one having on its edge a series of teeth, and the other hav formed by a displaced portion lar wall adapted to receive sa erally in different positions of rela tive adjustment of said members.

4. In a device of the class described, and in' combination, a pair of tubular sheetmetal members, one adapted to telescopically ,iieceive and automatically interlock with the other in numerous positions of relative rotative adjustment, one of said members having on its edge a series of teeth, and the other being provided with a transverse slit, and having a portion of its wall on the inner side of said slit displaced. to form a pocket adapted to receive said teeth severally in different positions of relative rot; tive adjustment of said members.

5. In a deviceof the class described, and in combination, a sheet-metal cap having a serrated end-flange and an external shoulder overhanging said serrated enddiange; and a sheet-metal shell adapted to be telescopically received Within said flange onthe cap and having means adapted to engage the serrated edge thereof.

' v 6. In a device of the class described, and

in combination, a sheet-metal cap having a serrated end-fiange and internal locking means on the inner side of said flange; and a sheet-metal shell adapted to be telescopically received within said flange on the'cap, said shell having external locking means engageable with the internal locking means on said cap, and having an outwardly displaced portion of its wall adapted to engage the serrated edge of said flange on the cap. In testimony whereof, we have hereunto set our hands this 11th day of January, 1909:
