FItIc'rIoN-LOCKED HINGE.

Specification of Letters Patent. Patented Sept, 26, 191 1. Application tiled Februarv 6, 1911. i

Serial No. 606,690.

To all whom it may concern.:

Be it known that I, ARTHUR BnANDEs, a

i citizen of the United States, residing at Cincinnati, county'of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Friction-Locked Hinges;I

bland I do declare the following to be a clear, i full, and exact description of the invention,

attention being called to thedrawin which v,accompanies this application and orms a part thereof. I .Q This 'invention relates to hlnges of the kind where one Iof two parts connected by the hingeis yieldingly held in an angular position to-which it has been adjusted Vwith .reference to the other part, by frictional rc sistance which opposes the free movement of the adj usted part.

ticularly .pointed out in the claims at the end thereof, will be found a full descriptirm of my invention, together' with its operation,

u parts and construction,.which latter is also illustrated in the accompanying drawing, in

. LWhich Figure l, shows the hinge in vertical, centralse'ction. Fig. 2, is a side-view ot' one of the two complementary hinge members. Fig. 3, is a \f'ertical section of the other complementa r y hinge-memlier. Fig. 4, is a frontview ot the hinge. Fig. is a front-view :if the hinge-member shown in Fig. 2.

T he hinge is described and illustrated in cormection with the windshield of an automobile. These devices consist usually of a stationary part A and of a lapB movably connected to it ,by means of hinges, there be ing one hinge at each edge of the shield. The movable, flap may be folded lup flat against the stationary part 'of the shield, or adjusted to any desired angle. It is held in such position by frictional resistance provided in the hinges and which opposes the free movement of one of the complementary hinge-n1embers on the other member, but

yields when a certain force is applied.

* In the drawing, C indicates one of the complementary hinge-members and D indicates the othpr member. One of these mem bers, C in t is case, is the stationary member of the hinge., itbeing provided with a tla'nge 9 where'py-1t is mounted upon the Vfitting hub 17 against it accordingly.

frame a of the stationary shield part A. This flange 9, supports a base l0 from which the hinge-pin c, rigidly connected, projects outwardly. 11 is a stud which also projects from this base butvperforms no function with reference to the hinge, serving merely as a means to permit connection of a brace l2 which sustains the wind-shield' onlthe auto. All of these parts of member Cas described are by preference contained integrally in one piece as shown in Fig. 2. The other hinge-member D which is the movable member of the hinge, consist substantially of a hub 13, open on its front-side and conically recessed. It is centrally perforated in the deepestpart of the recess at 14, the opening being fitted to receive hingefpin c, which extends through this opening and projects into the recess. An arm l on this member attached ly means of a flange 15 to fra-me b of the movable flap B of the windshield completes the hinged connection of this flap to the stationary part of the wind-shield.

Frictional resistance is provided to prevent the movable member `from swinging freely on hinge-pin c, and to hold this member in any position to which it has been moved by flap It (.fonnected'to it, the object being to hold this flap in any position to which it has been adjusted without requiring any special lmking-means. This resist- 'ance is so graded as to hold the flap in any position under conditions considered normal for a particular purpose, but permitting it to' yield when a certain force is applied. This frictional resistance is obtained by means of friction cone 16, fitted into the conical recess ot hub 13, so as to be in contact with the surface of this recess and provided with a hub 1.7, whereby it is mounted upon the extended parl: oi pui c. It is held on this latter to prevent it from following hinge-member D in a rotary direction by any suitable means as for instance by a pin 18 on hingepin c which extends into a slot 19 in hub 17 ol the cone. Such rotation may also be prevented by shaping the extended part of pine otherwise than round and by In whatever way this is done, it is donc in a manner which permits the cone to have full and 'unrestricted contact with the surface within the conical recess in the hub and which contact is maintained by a spring 20 closes the recess in hub 13 against the outside. The cap is screw-connected to be held in position as for instance by a nut 22 which bears against the outside of it and is seated upon a threaded extension 23 of hinge-pin c, which projects through a central perforation in said cap. The frictional Contact of cone 16 is maintained against wear by forcing it up on pin c and deeper into the conical recess, which is done by moving cap 2l farther into the hub so as to increase the action of the spring correspondingly. The opposing surfaces, that within the conical lrecess and that of cone 16 in contact with it,

may be roughened as for instance by corrugations to promote the frietional resistance, or the recess may be contalned in a body of packing 24 of friction-promoting material like wood or fiber as shownA in Fig. 3.

It will be noted that no lateral strain tending to either spread or compress the :trames of the shield, frequent cause of cracked glass and due to the action or re-aetion of the springs, is transmitted to these frames since the act-ion of the springs is entirely taken up in both directionsand neutralized within the hubs and between them and shoulders Q5 at the base of pin c beyond which these ett'ects do not extend.

These hinges permit complete folding up of one part of the wind-shield flatly against the other part and on either side ot the same, the particular side being determined by 'positioning the hinges accordingly Having described my invention, I claim new:

l. lin a friction-locked hinge, the combination of two complementary hinge-members, each provided with means for its attachment to the parts to be hingedly connectedv` one of the hinge-members comprising a hub having a central perforation which is diametrically enlarged on one side of it to form a conical recess, a hinge-pin provided on the other member which is fitted to the perform tion in the hub mentioned and extends into to the parts to be hingedly connected, one of the hinge-members comprising a hub having a central perforation which is diametrically enlarged on one side of the hub to form a conical recess, a cap to close thisrecess, a hinge-pin projecting from the other member upon which this hub is mounted and which pin reaches into the recess ot the hub,

a friction cone contained within this recess,r f

a spring provided between the cap and this cone yto hold this latter within the recess, means to preventrotation of thefcone with the hub and means to adjust the position of the cap to regulate the action oi' the spring.

3. In a friction-locked hinge for hinging the two parts of a wind-shield to each other, the i combination of two complementary hinge-members, one being in form of a perforated hub provided with an arm eXtend.-

ing from it which terminates in an attaching Aflange for connection, to one of the parts et the wind-shield, the other member comprising a base provided with a flange for attachment to the other part of the windshield and with astrid to permit connection to a brace and with a hinge-pin which receives the hub of the other hinge-member and thereby completes the hinged connection between the two parts of the wind-shield and means provided ont-he hinge-pin and in frirtional engagement with the hub to retard free rotation of' this latter.

In testimony whereof, lf hereunto ai'iX my signature in the presence of two witnesses.
