Toad whom it may 00.10am:

Be it known that I, GEORGE H. CHAPEL, a citizen of the United States of America, re-

ston. and State of Michigan, have invented certain new and useful Improvements in E e 'lasses. of which the folloWm 1s a s necraccompanying drawings.

This invention relates to improvements in eye-glass mountings and more particularly to the construction and arrangement of fin pieces of mountings and springs actuating the same.

The object of the invention is to provide a simple and cheap construction which is such as to greatly facilitate the assembling of parts and to give a strong and rigid bearing for thefinger-piece, the construction also being such as to provide a ready attachment for the spning and give a very neat To these ends the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims reference being had to the accompanyi 1g drawing in Wl1lCl1- Figure 1 is an elevation of eyeglasses embodying the invention; Fig. 2 is an edge VlQW of the same; F 3 is an enlarged perspective view of aportion of the mounting; Fig. i is an enlarged sectional detail through a portion of the mounting and finger piece and through the spring for actuating the ringer piece; Fig. 5 is an enlarged perspec tive view of a screw post; Fig. 6 is an enlarged detail of a portion of a mounting show ng a plan View of Fig. 7 and illustrata modified construction and Fig. 7 is a sectional view of the detail shown in Fig. 6 and showing parts in elevation.

As ill'ust'ated in the drawings .1, 1. represent-lenses which are held in the usual man nor by means of clips 2 formed integral 'ith the ends of the bridge 3 in the usual manner. Between the ends oi the bowed portion broadened and somewhat thickened to form bearing portions a each having an openin therein through which a post 5 extends and in which said post is adapted to turn freely. The post has a reduced lower end portion 6 which forms a shoulder 7 intermediate the ends of the post and the portion 6 is adapted to engage the opening in the bridge with its shoulder resting upon the upper surface or the supporting p'ortiona of the bridge, The

upper end portion 8 of the post which is of grezter diameter than the lower portion 6 is pro oed with a siightly tapered laterally pro ag drugs at its upper end forming a slight head i) on the post- 'uhich is rounded to provide a smooth upper surface and give a neat appearance. This head is also formed with the usual transverse slot 10 for the engagement of a screw driver and. the body Sis formed with a longitudinal groove 11' in one side extending from. one end of the slot 10.

A guard lever or". any suitable form and construction is attached to the lower projecting end of the post by screw-threading said end and screwing it into a scrcwthread ed opening in the lever which is thus held in engagement with the lat lower surface of the bearing portion a *uosite that surface which is eng ged hy the; shoulder 7 of'the post. The guard lever is constructed in the usual manner with a foz -u'ardly projecting A flat volute spring 1% is coiled about the' body 8 of the post with one edge resting on the upper surface of the bearing portion 4 of the bridge The inner end of the spring is inturned and engaged with the slot 11 in the post and the outer end of the spring is turned outwardly to engage a lug 15 formed or secured to the bridge or adjacent clip member of the mounting. This lug has a lateraliy extending lip 16 at its end to engage over the end oi the spring and hold the signing r ai'nst its seat upon the bearing portion 4- r the bridgl-z. The flanged upper end or head 9 on the post also assists in holding the spring 1 place upon its seat,

The spring so coiled about the post that it tends to turn the post in such Zl;Cli1'6CtiOI1 that its screWthrad-ed lower end will be screwed into the finger piece and thus preyent the accidental diseng fj'einent of the finger piece from the post The finger piece may he quit ly and ca; detached for the purpose of replacement or repair by disengaging the end of the spring from the lug 15, removing the spring, and then turning the post to disengage its screwthreaded end from the finger piece When the parts are in place, the finger piece has firm rigid bearing by its engagement with the under side of the bear'ng or support 4- of the bridge and the is attached in such a manner asto constantly i hold the screw post against unscrewing, it

is unnecessary to rivet or otherwise permanently Secure the post to the guard lever. While the guard lever is firmly held against wabbling by the post and the'broad bearing which it has against the bridge, the post turns freely in its bearing without binding sot-hat the spring will act upon the lever 4 through the medium of the post to turn the same and hold the guard in gripping position..': I In Figs. 6 and 7 a wire spring 17 is shown coiled about the post in place of the volute fiat spring 14:, one end of the spring 17 being inserted in the slot 10 of the post and support and the opposite end of the spring engaged with a suitable projection on the bridge or against the adjacent clip. It is obvious that the Wire .coiled spring operates in the same .manner that the fiat spring acts and that either formof springv may be used as de sired. l

Obviously changes may be made in the constructionand arrangement of parts without departing from the spirit of'my invention and I .do not therefore limit myself to the particular form or construction shown.

Having thus fully described my invention what I claim i$:-'- j I 1. In an eye glass mounting the combination of a support, a guard lever at one side 'of the support,-'a member having a bearing on the support to turn therein and about which the guard lever is attached, and a spring attached to said member at the opposite side of said support to turn the member and guard lever.

2. In an eyeglass mounting, the combination of a support having an opening, a rotatable member within said opening, a guard lever attached to said member at one side of said support and a spring acting upon said member at t e opposite side of the-support.

3 3. In an eye glass mounting the combination of a support havingan opening therein, a member rotatable within said opening, a bearing upon one side of the support, a guard lever attached to the rotatable member in contact wit-lithe opposite side of said a spring attached to and coiled about the rotatable member at the side of the support opposite that engaged by the to said support.

4. In an eye glass mounting, the combinat on of a support having an guard lever to position said lever relatively post rotatable within the opening and having a shoulder to engage one side of the support, a guard lcvernttached to the post in contact with the opposite side of the support, and a spring to turn the post.

5. In an eye glass mounting, the combination of a support having an opening, a post havinga reduced end portion to engage the openingand turn therein, and an end portion having a slot, a guard lever attached to the reduced end of the post in contact with one side of thesupport, and a coiled spring surrounding the post at the opposite side of the support with one end engaging the slot in the post to turn the same and position the guard lever relatively to the support.

6. In an eye glass mounting the combinapost to turn freely within the opening and raving a screwthreaded end, a guard lever having a screwthreaded opening engaged by the screwthreaded end of the post, and a spring coiled about the post to turn the post and hold its-screwthreaded end engaged with the guard lever.

7. In an eye glass mounting. the combination of a support having an opening, a guard lever engaging one side of the sup-port and v provided with a screwthreaded opening, a post having a reduced end to turn within the opening and formed with a shoulder to -engage the side of the support opposite that engaged by the guard lever, said post having a screwt-hreaded end to engage the screwthreaded opening in the guard lever, and a spring coiledabout the post and attached thereto to turn the same, said spring resting upon said support at the side thereof opposite that engaged by the guard lever.

' 8. In an eye glass mounting, the combination of abridge having a portion forming a support provided with an opening, a guard lever having a screwthreaded opening, a post having a reduced end projecting through the opening in the support and engaging the screwthreaded opening in the guard lever, said post being formed with a shoulder to engage the side of the sup-port opposite that which is engaged by formed with a longitudinal slot in one side, a flat convolute spring surrounding the post with one end engaging the slot in the post, saidspring resting upon the support around the post, and a lug on the support to engage the opposite end of the spring.

In testimony whereof I my signature in presence of two witnesses.
