f EYEGLASS-MOUNTING.
'To all whom it may concern:
Be it known that l, Fnnnnmon A. STE- rnxs. a citizen of the United States, residing at ,lrovidence, in the county of Providem-e and State of Rhode Island, have in rented certain new and useful Improve mentsin l lycglass-h'lountings, of which the following is a specification.
ltly invention relates to eyeglass mount ings provided with swinging nose clamps, and is primarily purposed to secure a uniform and relatively equal degree of pressure of each clamp upon the nose; to insure a correct tension of the clamps both in originally asseniblingthe mounting parts, and in subsequently adjusting the sameto compensate for changes of condition resultant upon wear; and, to attain these ends with'outa renewal or substantial reassemblageof parts.
. To the above ends essentially the invention consistsin the novel construction, ,arrangemcnt, andcombination of parts substantially as hereinafter described and claimed, and shown in the accompanying drawings wherein,
Figures 1 and 2 are front and plan elevationsrespect-ivel" of a pair of eyeglasses embodying the invention, Fig.- 3, .a. sec-- tion on a: a: of Fig. 2, Figs, :1 plan view of the bracket, Figs. 5 and 6, plan and side "elevations respectively of the barrel, and
Fig. 7 a section on line 3 y of Fig. 4.1
' Like reference characters ,indicate like parts throughout the Views.
'In'the construction illustrated the eyeglasses comprise the lenses 1 attaching lugs 2, edge lugs and bri ge 4. ,The end por-T tions of the bridge are flattened to form brackets or supports 5 connected with the lugs 3. Screws (Sconneet, the mountings to the lenses. Operating levers 8 provided with the usual guards 9 and operating projections 10, constitute the nose clamps in this instance.
In carrying out the invention the supports 5 are each provided upon their upper faces with an annularly arranged series of projections, serrations, or ribs, 12 preferably inclined or V shaped surrounding a vertical opening 13. Loosely mounted in each opening 1.3 is a pivot member 14 provided upon its lower end with a head 15, and having adjacent the head an enlarged bearing portion 16 upon which is loosely journaled the operating arm, 8, and which forms a shoulder 17 which bears against the lower face Specification of Letters Patent; Patented Apr. 26,
Application filed November 26, 1909. Serial No. 529,865.
member which projects above the sup "tion with a support and a swinging,, nos e. .clamp, of a pivot member ourrialed in the of the portion 5 to prevent binding of the arm portions. The upper end of the pijvot pen 5 is provided with-a screw thread 18; which engages a screw thread 19 upon the interior of a barrel 20, The barrel is'providedfat its lower end with projections or serrations 21, preferably inclined or V shaped, upon its top with a lateral annular flange or extension 22'provided with an opening 24. Around each barrel-is a spiral operating spring 26, one of whose ends27 enters and is retained in the opening 24, and Whose other end 2S engages the arm 8; v I ii 7.0
The nose, clamps are operated in the usual well known'manner by the compression or release of the finger-projections '10 inconjunction with the tension of the springs 26 upon the 'arm portions 8'. The projectioi 21 of the barrel register between'the proje tions 12, of the mounting which normally prevents any rotation of th'e'barre'l 20 upon the threaded portionof theIscrew The inclined shape of the projections facili the adjustingof the parts. If and when it is desired to change the degree o'f pressure of a spring upon an arm the. em-( 15in turned amtil it descends a distance equaljto the depth of the'projections 12 or 21, and 3, is then -mannally elevated to lift the barrel i out of engagementwith the mounting, jT-he barrel is then turned totighten or contract the coils of the spring 26 the desireddegrew t and there hcld,.\vhile the screw 13 is being 30 turned to again bring the teeth of the ba-rrel into engagement with the projections} "12, and bringthe head 15 into a position tosup port thearni portion 8 of the nose clamp. What I claim is', i
1. In an eyeglass mounting, the com support about which the clamp, is mounted .to swing,a spring surrounding the pfivot;
member and exerting pressure upon clamp, and means for contracting the spring.
2. In an eyeglass mounting, thecombination of a support, a nose clamp, a pivot member about which the nose clamp is mounted to swing, a spring surrounding the pivotmember and/exerting pressure upon the clamp, and means upon the pivot member cooperating with the support for regulating the pressure of t spring. 3. In an eyeglassmounting, the combinetion with a support and a nose clamp, of a pivot member loosely connecting the support and the clamp, a spring around the pivot member and engaging the clamp, and rotatably adjustable means upon the pivot member for engaging a portion of the spring. 7
I. In an eyeglass mounting, the combination with a support and a swinging nose clamp, of a pivot member jonrnaled in the support and upon which the clamp is mounted to swing, a rotatably adjustable barrel upon the pivot member, and a spring surrounding the barrel having one end se-, cured to the barrel and its other-end engaging the clamp.
5. In an eyeglass mounting, the combination with a support and a swinging nose clamp, of a pivot member jonrnaled in the support and upon which the clamp is mounted to swing, a rotatably adjustable barrel upon the pivot member, a spring upon the barrel engaging the clamp, and means upon the support for maintaining the barrel in adjusted position.
(3. In an eyeglass mounting, the combination of a support provided with projections,
a nose clamp, a pivot member loosely connecting the support and the clamp, a barrel rotatably movable upon the pivot member and provided with means for engagingthe projections, and a spring upon the barrel and engaging the clamp.
7. In an eyeglass mounting, the combination of a. support provided with projections, a nose clamp,- a pivot member connecting the support and the clamp, a barrel rotatably movable upon the pivot. member and provided with projections adapted to engage the projections of the support, and a spring upon the barrel and engaging the clamp.
8. In an eyeglass mounting, the combination o'l a support provided with inclined projections, a swinging nose clamp, a pivot member jonrnaled in the support and about which the clamp is mounted to swing, a barrel rotatably adjustable upon the pivot member provided with inclined projectionsadapted to normally register between the projections of the support, and a spring| upon the barrel and engaging the clamp.
9. In an eyeglass mounting, the combination with asupport provided with projections, a swinging nose clamp, a pivot member journaled in the support and upon which the nose clamp is mounted, said pivot ing and provided with a screw thread upon the-end adjacent the projections, and provided with a shoulder near its opposite end adapted to engage the face of the support, a head upon the end of the pivot member near the shoulder, a nose clamp upon the pivot member intermediate the shoulder and the head, an internally threaded barrel engaging the threaded portion of the pivot member and provided with projections adapted to engage the projections of the support, and a spring upon the barrel in contact With the clamp. I
11. In an' eyeglass mounting, the combination with a support. and a swinging nose clamp, of a pivot member jonrnaled in the support and upon which the clamp is mounted to swing, a rotatably adjustable barrel upon the pivot member provided with a laterally extending upper portion, a spring surrounding-the barrel having one end attached to the extending portion of the barrel, and its other end in contact with the clamp.
In an eyeglass mounting, the combi nation with a support provided with projections, of a pivot member jonrnaled in the support provided with a screw thread upon one end, a head upon the other-end of the pivot, bearing means intermediate the head and support for interspacing the head from the support, anose clamp pivotally mounted upon the bearing means, a barrel rotatably adjustable upon the threaded end of the pivot member provided with means for engaging the projections of the support, and a spring attached to the barrel and engaging the arm.
In testimony whereof I have aliixed my signature in presence of two witnesses.
