eht JAPe-IaL a To all whom z'tmay concemr Be it'knownthat I, 'PETERTOBIAS Cannas'rnorr, a citizen of the United States, and aresident of the city of Chicago, in the. county of Cook-and State ofIllinois, have invented a certain new .and useful Improvement in LockingeHin'ges; and I do hereby declare that the following description ofmy' saidinvention, takemin connection with the accompanying sheets of. drawings, formsa full, clear, and exact specification, which will enable-others skilled in the art to which it appertains to. make and use the same.

This invention has general reference to improvemeritsin locking hinges,- and it con sists, essentiallin the novel andpeculiar combination 0 artsand details: of con struotion', as hereinafter first fully set forth-g anddescribed, and then pointed out, in the claims.

. the drawings already referred to, which serve: to-- illustrate my said invention more fully, Fi rel is a perspective view --of an automob' e wind shield equipped with my'l'ocking hinge;'Fig.,2 is a front elevation.

Fig. 3 an enddevation thereof, Fig. 4 is a side elevation of my (19''. vice' detached, and- Fig. 5 a longitudinal section of the same, takenin the direction of e arrow pointers in line 0- O of Fig. 4." Fig. 6 is a s de'elevation of one of the leaves of the hinge detached, and Fig. -7 a tflinsa verse section looking in the direction of the arrow pointers in line-l- 1' of Fig. 5..- Fig; 8 is a sideelevation of the leaf' opposed to that shown in Fig. .6," and Figs. 9 and 10, are an elevation nd Flam respectively, of de-- tails of construction. Fig. 11 is a side'elevation of a fragment of my hinge as applied to an automobi e wind shield. The object of my invention is: the production of a locking hinge. which may" be applied to the usua type of wind shields used on automobiles; to horizontall or vertically pivoted windows in ofiice bui dings, to cel- 19.:- windows, and, in fact to any lace where a hinge is desired wherein t e portion hinged will remain. in the position it was last placed until removed therefrom by manual pressure.

It is a further aim of my invention to arrange in the carrying out thereof, certain means whereby the effort required to operate the hinge may be increased or reduced to meet. the various requirements.

5A,: In; Figs. 1,2, and .3,--'ind ioates} an ward extension of the: foot 1" @bwd' of utomobile sis is .recaneam, fi dtosaid arena! y 'suitableclips- 19,. which; glass forms C -fare the lower eaves of my lockiugfhinge D, wh1'c'h leaves are afiixed to. the uppercor- :ners of glass B in any suitable manner and connected. with the bodyof the atrtomobile by diagonal braces-G for stiffening purposes.

E are the upper leaves of the hinge, at the free ends of which are rotatabl attached heads F, which heads are attached. to the opposite" edges of a rotatable glass H,-which, as seen in Fig. 3,;is adapted to be oscillated independently about. the free ends or. the upper leaves E, so that any desired pitch: orposltion withimthe limits of the hinge, {111?b9i1'I1Pfl-It9dto the glass 7 he lower leaf 0, Figs. 4, 5, 8', has formed at one end a diskdike hubofboes=.1, which boss may be formed tan gmtiall .to the as particular may,

may be-most desirablefor; tho.- ui'i'to' w has a concentric projection 2 smaller diameter, and an axial, screw threaded shank or stud 31 n the face of the projection '2 isdrilled a lurality of .concentrically arranged, .e ually spaced holes 4, Fig. 7, into whic are tightly pressed cylindrical, steel tubes, preferably .hardened, which tubes 5 are adapted to receive helical springs 6,1the-u per ends of which support balls 7-, which 7 vills are just a. nice fit in said tubes and project beyond the face of the rejection-2 practically onehalf oftheir lameter. -Fitting over said projection is an internally bored boss 8 of the upper leaf E. This latter boss may also be tangent to the edge of the leaf E and offset therefrom, or it may be centrally arranged in the same lane. In the bot-tom of the internally bore portion of boss '8, there is fastened by rivets 9 or'otherwise, a carbonized steel plate 10, which plate is drilled with a plurality of coucentricallyarranged,

. v If -m' ay. beioifset to said leaf (1,, as? shown; in Fig. 5;,or a direct continuation thereof,

equally spaced holes 11, which holes 11 are in register with the balls 7 -when the parts are assembled. Said boss'8 and'plate 10 have a central, axial, circular opening'lSZ, which is adapted to fit over the shank or stud 3 on the boss 1. It will now ,be ob-' served that when the boss .8 is slipped into place upon boss 1, the balls *7 will project mto the holes 11, and that if. revolution of either leaf be attempted, the said bosses will either be forced apart, or the balls 7 will be compelled to retreat into the tubes 5, thereby compressing the springs 6. To prevent said bosses from being-so forced apart, I place over the threaded stud 3 a washer 12 and a nut 13 which latter, when screwed up,

will effectually prevent anyspreading tend ency; Revolution of this nut is prevented by a set screw 14, bearing upon said shank or stud, or I may emplo, 'a castellated nut, as seen in Fig. 11, wit a cotter pin 15. Attention is now called to the fact that the effort necessary to oscillate either of theleaves will be directly proportionate to how tightly nut 13 is screwed up, and it is obvious that as the balls 7 are entered in holes 11, effort is required to dislod e them by an enforced retreat into the tu es 5, before either leaf may be moved. While the balls are so retreated, the oscillation or revolution of the leaf or leavesis an easy matter until the next succeeding holes 11 registerwith the balls 7, whereuponsaid balls, acted upon b the compressed springs 6, engage said ho es.-

When this device is used as a hinge for automobile wind shields, the washers 12 become the terminals for the braces G, hereinbefore referred to. When so'employed, I form on the free ends of the leaves E, bosses 8, which are constructed preciselyas are bosses 8, and which co act with heads F to permit the independent oscillation of top" shield H. These heads F are made with the same elements as boss 1, and operate in exactly the same manner.

Locking hinges of the type described are generally made from bronze for the more expensive hinges, or from malleable iron for. the cheaper grades. As is well known, both of these metals are very ductile and not" of dense grain, so that a hinge operated with the balls bearing directly upon the bare metals, would not only have the holes 4 quickly enlarged, but would also have a pathway cutlbetween the holes 11, as a result of which the device wouldbecomeuse- 'less in a very short time, because of inability 11 to effect the proper operation of the hinge. L

Having thus fully described my invention, I claim as new and desire to secure to myself by Letters Patent of the United States 1. In a hinge, a leaf with a boss, said boss having a series of concentric holes in the face thereof, hardened steel tubes forced into said holes, balls fitting the interior of saidtubes, means within said tubes to force said balls outwardly, a second leafpossessing a boss, a hardened steel disk fixed to the face thereof, there being a series of concentrically arranged pockets in the face of said disk,

which pockets are in register with said balls, and adjustable means for retaining said bosses in juxtaposition to each other.

2. In a hinge, a leaf with a boss, said boss having a series of circular holes in the face thereof, hardened steel tubes forced into said holes, balls fitting the interior of said tubes, helical springs in said tubes tendin to force saidfballs outwardly, a second lea possessing a boss, a hardened steel disk fixed to the face thereof, there being a series of concentrically arranged pockets in the'face of said .disk,"which pockets are in register with said balls, and adjustable means {for retaining said bosses in juxtaposition to each other.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
