Application filed Noveinber, 1921. Serial no. 512,734.

To all whom it may concern:

Be it known that I, PERCIVAL W. JoNns, a citizen of theUnited States, and a'resident of Providence, in the county of Providence and State of Rhode Island, have invented an Improvement in Construction for Eyeglass Parts and the like, of which the following is a specification.

This invention relates to the construction of eyeglass parts and the like. One of the objects thereof is to provide a simple and practical arrangement whereby metallic and non-metallic parts are securely connected together in devices of the general nature of that herein described. Another object is to provide a nosewng-aging "member for eyeglasses and the like of inexpensive and secure construction and well adapted to meet conditions of usei Another object is to provide an art for forming constructions of the above nature which is simply and conveniently carried on and dependable in its results. Other objects will be in part obvious and in part pointed out hereinafter.

The mvention accordingly consists in the features of construction, combinations of elements and arrangement of parts and in the various combinations of 'ste s, all as will be illustratively herein descri ed and the scope of the application of which will be indicated in the ollowing claims.

In the accompanying drawing in which is shown one of various possible embodiments of this invention and certain steps involved in the making thereof,

Figure 1 isian ed e view. of a portion of a nose-engaging mem er or nose adi";

Figure 2 is a similar view 0 the samev parts at a later stage in their construction;

Figure 3 isa longitudinal sectional view of the completed device, and

Figure 4 is.a rear view of the parts shown in Flgure 3.

Similar reference characters refer to similar arts throughout the several views of the rawing.

' Considering Lnow thisdrawing in detail, there is shown in Figure 1 a metallic base of a nose-enga ing member such as is used in the so-cal e finger piece type of e eglasses. This memberwlll be referred to a nose pad althou h it is to be understood that various of the broader features of this invention are applicable to difierent types of construction. This device comprises the manner that not 0 'derstood that t erein as plate 10 having on its rear a rectangular shoulder 11 terminating in a post 12. The parts-11 and 12 serve merely to make suit portion of the eyeglasses, and have in themable connection with the lever arm or other I selves nothing to do with the present invention. On the, opposite or operative side of flattened into the form appearing at 13,;

for a purpose hereinafter described. By

this action as distinguished from swaging,

the base portionsof the post are-not enlarged or deformed.

The edge portions of the plate 10 are preferably not only rounded or beveled on their rearside as indicated at 15 but also on the opposite side as shown at 16 for a hereinafter-described. K With the metallic parts thus formed, the facing shown at 17 in Fi re 3 of the drawing and properly shape 1s fitted w1th1n a purpose I mold diagrammatically indicated at 18 and heated. The member 17 which is formed of celluloid is thus rendered soft. It may be here be noted that the term celluloid is used in abroad sense to comprehend'various non-metallic materials having similar characteristics.

The softened member 17 with the mold still in position is then forced downwardly toward the forward side of the plate 10 and these parts are ressed together in such 11? are the'parts 13 with their heads 14 embe ded in the celluloid but the latter fills all interstices between them and the part 10 and is urged downwardly to the edge formedby the beveled surfaces 15 and 16.

The mold 18 is then removed and the celluloid member ermitted to cool, it being unhe bottom wall of the mold is roughened or knurled as indicated at 19 so as t rovide a similar exposed surface on the co luloid member.

In the use of the devices it will be seen that the celluloid member having a greaterthicks ness than the pipe of the posts 13 with their heads 14, covers all metal surfaces and is securely locked in position. Furthermore,

- device.

the tapered edges of the base plate prevent the appearance of the device is enhanced and at the parts are securely united one to another with a minimum of labor.

"As various changes-might be made in the above construction and as the art herein-described might 'be varied, all without departing from the sco of this invention, it,

l is tobe understood that all matter. herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a sense. I elaimas' my invention 1. nose-eng device for eyeglasses comprising, in .eom'

mation, an elongated with the headsvthereof, the ed non-metallic member being mol ed over the and flattened metal member han' Y one face thereof a projection for .z.

. connection with the other parts of the eye with an enlarged glasses and on the other face thereof a pair ofprojectin metal posts, one ad'aeent eachv 811 of said ase member and one provided be r oeuui i m a m na i amem r o 01 l last face of said base member and shaped substantially the contour thereof, said celluloid mem of greater thickness than the entire length of said posts, completely covering sai post with said heads thereof, the edges of sai celluloid member being molded over and s and interlockin covering the adjacent edge of'said base member throughout the circumference thereof, and the outer face of said celluloid member being roughened to engage and grip the nose. 2. A nose-engaging device for eyeglasses comprising, in combination,- an elongated.

metal base member having on one face there i of a projection'for making connection with other parts of the eye lasses and on the opthereof thereby reduced in thickness, and a non-metallic member resting against said second face of said base member and shaped substantially to the contour thereof, said non-metallic member being of greater thickness than the total length of said posts, completely covering said posts and interlocking of sai vreduced edges of said metal base member,

cove said edges and substantially meetlng sai bevel, and the outer fare. of said with enlarged eads, said first face of saidbase member belng'beveled and the'edges non-metallic member being roughened enga e and grip the nose.

n testimony whereof, I have signed my name to specification this 25 day of October, 192 1 PERCIVAL w. JONES:
