SPECTACLE TEMPLE AND METHOD OF MAKING THE SAME Filed May 27, 1926 F g v [711v 671/ or 1 Jam as TM Wglah Jib 771)?" Patented Nov. 5, 1929 JAMES W. WELSH, 0F PBOVIDENCE,-EHODE ISLAND, ASSIGNOB TO BAUSCH & LOMB OPTICAL COMPANY, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK SPECTACLE TEMPLE AND METHOD OF MAKING THE SAME Application filed May 27,

The present invention relates to spectacle temples and methods of making'the same.-

The chief object of the invention is to provide a new and improved spectacle temple of the combinednnetal and non-metal type that shall be cheap to manufacture'and very'eficient in operation.

The invention will be described in connection with the accompanying drawings, in which Fig. 1 is a perspective view of a spectacle temple constructed according to a preferred embodiment of the present invention, shown hinged to a lens frame, with parts broken away, for clearness; Fig. 2 is a fragmentary perspective view of a reinforclng rod that is adapted to be combined with a non-metal tube to produce a temple according to the present invention; Fig. 3 is a fragmentary elevation of the same; Fig. 4 is an elevation, partly in longitudinal section, of a complete temple; Fig. 5 is a longitudinal fragmentary section of a non-metal tube that is adapted to be combined with the reinforcing rod shown in Figs. 2 and 3 to produce a temple according to the present invention, the tube being bent at one end and otherwise treated preparatory to the introduction thereinto of the reinforcing rod; and Fig. 6 is a similar fragmentary longitudinal section of the tube, with the reinforcing rod therein.

The preferred temple of the present 1nvention comprises a non-metal member, shown as a seamless tube 2, preferably flattened and tapering on its outer surface in the plane of the flattening from the forward end towards the rear end, as is illustrated in Fig. 1. reinforcing member, such as a metal rod, 1s enclosed in the bore 6 of the tube. The reinforcing rod is provided with a body portion 8 having a reduced end portion 9 extending in line with the body portion. A metal strip is provided with doubled-over

portions

10, 12 in contact with each other, and with an intermediately disposed eye 14. The contact ing

portions

10 and 12 are provided with alined openings 23 through which the reduced end portion 9 extends, the parts being secured together by riveting over the extreme tip of the reduced end portion 9 at 25. The

strip

10, 12 is thus securely held 1n 1926. Serial No. 111,980.

place between the riveted tip 25 and a shoulder 27 at the junction between the body portion 8 and the reduced end portion 9. The

parts

10 and 12 may also be soldered together and soldered to the body portion 8, or a spot weld may be used. i I

To assemble the tube 2 with thereinforcing rod, the body portion is mounted in the bore 6 of the tube through an opening 18 provided in the side of the tube 2, near one end. To facilitate the assembling operation, the end portion 20, to one side of the opening 18, is bent out of line with the axis of the tube, as is illustrated in F igs. 5 and 6. After the rod has been mounted in place, the end portion 20 is restored to its former position, as illustrated in Fig. 4. The eye 14 is left"extending through the opening 18 and'beyond the side of the tube. V I c If desired, the

strip

10, 12 may be of smaller thickness than the body portion 8, and it may be provided with flat faces at their contactmg surfaces, as shown. The provision of the flat faces permits the

portions

10 and 12 becoming readily soldered together to form an integral union.

The projecting terminals 1 9 of the

portions

10 and 12 beyond the body portion 8 bite into the non-metal material of the tube 2, serving to anchor the reinforcing core in the tube. By means of the eye 14, the temple may be hinged at 11 to the end'piece 13 of a'lensholding frame 15. I

The ends of the tube 2 may be plugged with non-metal material in a manner that is now well known, or closed in any other desired manner, completing the temple. Modifications will readily suggest themselves to personsskilled in the art, and all such are considered to be within the spirit and scope of the present invention, as defined in the appended claims.

' What is claimed is:

1. A spectacle temple comprising a rod having a body portion provided with an end portion adapted to be positioned near the head of a wearer and with an end portion at which the temple is adapted to be hinged to a lens-holding frame, and a doubled-over member the doubled-over portions of which are provided with alined openings through which the second-named end portion extends, the member being provided with an intermediately disposed eye, the temple be- 5 ing adapted to be hinged to the lens-holding frame by means of the eye. 2. A spectacle temple com rising a nonmetallic tube, and a rod in t e tube having a body portion provided with an end portion adapted to be positioned near the head of a wearer and with an end portion at which the temple is adapted to be hinged to a lens# holding frame, and a doubled-over member the doubled-over portions of which are provided with alined openings through which the second-named end portion extends, the member. being provided with an intermediately disposed eye, the temple being adapted to be hinged to the lens-holding frame by means of the eye, the terminals of the doubled-overportions biting into the nonmetal material of the tube.

3. A method of making an article of the class described that comprises providing a rod having a body portion and a portion projecting from the body portion provided with an eye, providing a tube with a relatively small side opening, bendingthe tube at a point where the side opening is located 3,; to increase the size of the opening, inserting the body portion in the bent tube through the side opening, and restoring the bent tube to its original form.

4. A method of making a spectacle temple 3,? that comprises providing a metal rod having a body portion, and a member secured to the mediately disposed eye, the doubled-over contacting portions beingprovided with alined openings, and a rod having a bod portion, an end portion adapted to be positioned near the head of a wearer and a reduced end portion separated from the body portion by a shoulder, the reduced end portion extending through the alined openings with the shoulder contacting against the member, the rod being secured to the member, and the temple being adapted to be hinged to a lens-holding frame by means of the eye.

7. A spectacle temple comprising a nonmetal member, a rod in the non-metal member having an end portion adapted to be positioned near the head of a wearer and an end portion at which the temple is adapted to behinged to a lens-holding frame, and a member secured to the second-named end JAMES W.
