1 Application filed December 15, 1925. Serial No. 75,570.

Thisv invention relates to improvements in the construction of hinges more especially adapted for use in connecting temples to ophthalmic mountings; and the object of this invention is to so mount a pivoting bolt in the hinge as to positively lock the bolt against relative rotation therein by thread ing the bolt in one of the ear members of the hinge and providing a lock nut on the 1 threaded end thereof, which construction serves in addition to locking the pivot bolt against rotation, also serves by-adjustment to take up wear or lost motion between the interengaging hinge ears or members to obtain just the desired friction in the joint to prevent looseness of the templeQ With these and other objects in "view, the invention consists of certain novel features of construction, as will be more fully described, and particularlypointed out in the appended claims. 1 I

In the accompanying drawings Figure 1 is a perspective View illustrating a fragmental portion of" an ophthalmic frame or mounting and showi'ng'my improved hinge as connecting the; temple to the end pieceof the frame. 1 I

' Figure 2 is an enlarged perspective view showing the hinge-plates with a plurality of interengaging cars, a pivot bolt passing ,through the ears with the nut threaded on the end thereof.

Figure-3 is a modification showingJ-an enlarged perspective view partly in section with one arrangement of a pivot bolt threaded into one'of the ears and havinga lock nut screwed onto its end.

Figure 4 shows another form of hinge. in which one of the plates has a pair of outside or end ears, the other plate having a single ear positioned between the end ears, and the pivot bolt being passed through both side ears and'threaded in one of the outside ears -with the lock nut threaded onto the end of the bolt.

It is found inthe practical construction and operation of temple hinges for ophthalmic mountings that the pivot pin often works loose permittin'ga looseness in the joint and permitting a wabbling motion of the temple, which is very objectionable and in some cases injurious to the wearer as the lenses are thus permitted move about .on the face out of there uired set positionand to obviate this diificu ty, I have provided a hinge having interengaging-hinge ear. members in one of which members is-threaded a portion of the Pivot bolt and in which we have=alsoem- 'ployed a binding "nut, which construction performs two functions first, the binding nut cooperates "with the threaded portion of the bolt in the ear member to serve as arlock for the bolt to effectually prevent relative rotation of the bolt during the swinging action of the temple; also-this nut when employed in suclra structure as that illustrated in *igure 3, where the bolt is threaded .into the intermediatefear of the hinge, also serves to force the outer ear against the next adjacent ear of the hinge to bind the same togetherto take upwear and ,lost motion between the parts'and prevent looseness of the temple so as not to detrimentall affect the vision of the wearer;.a'nd the to lowing is a detailed descriptionoff'the present embodiment of our inventionandshowing a construction of hinge by which 'these advantageous results may be accomplished:

With reference to the drawings, 10 designates an eye-wire of a non-metallic opthalmic mounting in which the lens 11 is set,

\ and 12 the end piece to which is hinged the temple 13 by our improved construction of hinge l4.

These hinges may, insome cases, be constructed with hinge plates 15- and 16, See Figure 3 the plate 15 having hinge cars 17 and 18 and one or more intermediate hinge ears 19; while the plate 16 is provided with hinge ears Q'Oand 20 set between the hinge on ears 17, 18 and 19 of the plate 15. These sets of ears are provided with an axially aligned bore to receive a common pivot bolt 21. This bolt being preferably provided with a tapered under head portion 22 to fit into a correspondingly-tapered recess 23 in the ear. This bolt is also threaded through one intermediate ear 19 of the plate 15 and.

is provided with a lock nut 24: preferably tapered as at 25 on its inner face to engage 1 a correspondin ly-shaped recess 26 in j the ear 17, by whic construction it will be seen that'any looseness betweenv the ears 18, 19 and 20*,may be taken up by a rotation of the bolt to draw ear 19 against car 20 and if .105

looseness occurs between the ears 19 and20 this may be taken up by setting up the nut -24; This nut also cooperates with the thread in ear 19 toform a positive lock for the 'bolt to prevent any relative movement of the bolt in its cars 13' 18 and 19. A wrench 35 is shown above the nut 24 in Figure 2. j

A similar elfect to that above described is obtained by the construction illustrated in Fl re 4, in which the hinge'plate 27 is provi ed with outer or end ears 28and 29 be-- tween which the ear 30 on the plate 31 ex- ,tends. The head of the pivot bolt'32 is pret.

erablg taered as at 33 to engage a correspon ing 'y-shaped recess in the ear 29, while this pivot bolt is threaded in the. ear-28.

The outer portion of this ear is counterbored as at 34 to receive a correspondingly tapered faced nut 25, which nut serves as a lock to positively prevent rotation of the pivot bolt I inits ears 2 8 and 29; also by this improved construction of hinge, it will be seen that the pivot bolt upon being set up will obtain exactly the desired friction between the different hinge ears of the hinge, a lock nut is then screwed onto the outer end of the bolt to positively loclt this bolt against any relative movement to either loosen or tighten the same thereby providing a hinge which will retain the desired frictional action be; tween the hinge ears, and if these hinge members should become worn its desiredfrictional action may be again restored to its original working condition by a simple adjustment of both the bolt and nut.

\ Bv forming a taper on the under side of the head and on the nut of the bolt and fitnemesis privilege of resorting to all the mechanical changesto which the device is susceptible, the invention being defined and limited only by theterms of the appended claims.

We claim:

1. A temple hinge comprising a pair of hinge plates having a plurality of interengag ng hinge ears, each of the outer ears of the-set having a tapering socket formed in its outer face, a pivot bolt extending through said ears and threaded into one of them, said bolt having a tapered head portion seated in one ofsaid tapering sockets, and a tapered binding nut fitting into the corresponding socket in the otl er of said outer ears and threaded onto the end of the bolt to lock the bolt and bind the ears.

2. A temple hinge comprising a pair of hinge plates, one having spaced opposite end ears and an intermediate ear, the other of said plates having spaced ears fitted between the first mentioned cars, a pivot bolt extending through both sets of said ears having a head engaging one end ear, and a lock nut engaging the opposite end ear, said bolt being also threaded through said intermediate ear.

3. A temple hinge comprising a pair'of hinge plates, one having spaced opposite end ears and an intermediate ear, the other of said plates having spaced ears fittedbetween the first mentioned cars, a pivot bolt extending through both sets of said ears having a tapered head seated in a correspondingly shaped socket in one end ear, and a tapered lock nut seated in a correspondingly-shaped socket in the opposite end ear, said bolt being also threaded through said intermediate car, and said bolt and nut being independently adjustable to each to regulate the friction between different sets of said hinge cars. In testimony whereof we afiix our signa tures.
