RATCHET HINGE Original Filed Dec. 28, 1927 lk wilr;

Patented Nov. 2, 1937 UNITED srAr-Eis 2,097,651 RAT CHET HINGE Peder 0. Starfgeland, Los Angeles, Calif., assignor of Calif one-half. to Myer (J. Cohen, Los Angeles,

m Refiled for abandoned application Serial No. 243,058, December 28, 1927. This application December 7, 1936, SerialNo. 114,658 r V 5 Claims. (01. 16-141) The center hub has ablock. l8 fixed therein,

, My invention isa ratchet hinge for doors, having the ratchets completely enclosed in the hubs ofthe-hinge. This is a substitute application of my abandoned application, Serial -No. 243,058, filed December 28, 1927, allowed December 13, 1929 and forfeited for failure topay the final fee.

An object of my invention is the construction of a ratchet hinge, with the ratchets entirely enclosed in the hubs of thehinge and with a pintle extending through said ratchets, the pintle holding the ratchets in alignmentand forming means to remove one of the sets of ratchets when it is desired to assemble and disassemble the hinge, such as for taking a door ofi the hinges.

Another object of my invention is the construction of an enclosed ratchet hinge with what may be termed a fixed ratchet connected to one of the center hubs of a hinge leai, and having opposite ratchets engaging in keyways in the adjacent hubs of the other hinge leaf. These latter ratchets are slidable and press against the fixed ratchet by means of springs which engage washers, such washers being caught in the grooves in the hubs having the slidable ratchets. A pintle extends through the central hub and the hubs adjacent thereto, and preferably has its upper and lower ends fitting in sockets in nuts secured to the upper and lower hubs of a hinge leaf.

My invention will be more readily understood 7 from the following description and drawing, in which:

Fig. 1 is a plan View of a hinge as if taken in. the direction of the arrow I of Fig. 2.

Fig. 2 is an elevation of a hinge as if taken in the direction of the arrow 2 of Fig. 1.

Fig. 3 may be considered a vertical section substantially on the line 3-3 of Fig. 1 in the direction of the arrows, through the center of the hubs, with certain of the interior part shown in elevation.

Fig. 4 is a horizontal section taken on the line cylindrical. The upper and lower hubs have bushings l5- fitting therein, such bushings each having a pair of opposite grooves It. The bushings have an internally threaded section I! at the top and at the bottom, respectively, of the hubs l4.

such block having ratchet teeth [9 at both ends, that is, at the top and bottom, and this block has a bore through thecenter to accommodate the pintle 2B, which pintle has a central enlarged section 2| withreduced ends 22 and shoulders 23 between such portions.

In each of the bushings of the hubs [4 there is a slidable ratchet 24 having teeth 25 and opposite splines 26, these splines fittingin the groove it of the bushings |5.. Bearing against each of the ratchets 2-l there is a coiled spring 2'l whi ch bears against a washer 28, suchwasher having opposite tongues 29 fittingin the grooves IS. The ratchets 24 and the washers 28 have a bore to slide on the reduced part 22 of the pintle.

There are two slidable ratchets, one in each of the hubs l4 and engaging the teeth on the top and bottom of the central ratchet block [8. The pintle and assembly are held in position by means of lower and upper nuts 30, such nuts having a reduced threaded section 3| engaging in the threads l7 and. having sockets 32 to accommodate the upper and lower ends of the pintle 20. These nuts may have a screw-driver kerf 33, if desired.

The assembly and disassembly of the hinge is believed apparent; however, it may be stated that it is desirable to solder the ends of the springs 21 to the ratchets 24 and to the washers 28, so that these may be lifted oii the reduced end of the pintles as a unit. However, presuming the hinges are to be disassembled, the lower nut 39 may be removed and, with this nut, the lower slidable ratchet, the lower slidable washer and spring will drop downwardly by gravity; and if desired, the pintle may be then removed. If the upper nut is first removed, then the upper end of the pintle may be grasped by the fingers and pulled upwardly, lifting the upper ratchet, spring and washer, such ratchet then resting on the shoulder 23.

It will be seen by my construction that I secure a double ratchet action on account of the central ratchet block and the two slidable ratchets in the upper and lower hubs. In addition, the pressure of these ratchets together may to a certain extent be regulated by the degree to which the nuts are threaded into the upper and lower hubs.

It will be apparent by the above description that the ratchet mechanism is entirely enclosed in the hubs of a hinge and thereby is not exposed to dirt or dust nor does it give an unsightly ap-. pearance. In fact, the ratchet hinge made in accordance with my design cannot be distinguished from the ordinary type of hinge, except as to the action.

Various changes may be made in the principles of my invention without departing from the spirit thereof, as set forth in the description, drawing and claims.

I claim:

1. A hinge comprising in combination a first leaf having a first hub with a ratchet fixed therein, a second leaf having a second hub adjacent" thereto with a ratchet slidable but non-rotatably mounted therein, a spring bearing on the slidable ratchet, a washer bearing on the' spring, a

pintle extending through said ratchets, spring'and Washer, a nut threadedly secured to a hub of one of the leaves, said nut having a socket, the end of the said pintle fitting in said socket.

2. A hinge comprising in combination a first leaf having a hub with a fixed ratchet therein, a

second leaf having a hub with a bushing therein, said bushing having a groove, a slidable ratchet mounted in said bushing and having a spline engaging the groove, a pintle extending through said ratchets, a nut threadedly secured to a hub of one of the leaves and-having a socket in which an end of the pintle fits, and means operated bythe nut to exert a pressure on the slidable ratchet.

3. A hinge comprising in combination a hinge leaf having a hub with a fixed ratchet mounted therein, a second leaf having a pair of hubs on opposite sides of the first 'hub and having slidable ratchets therein, said latter ratchets being non-rotatable as regards saidsecond hubs, a pintle extending through the ratchets, nuts secured to the top and bottom hubs of the hinge, each nut having means to engage and center said pintle, and means operated by at least one of the nuts to exert a pressure on at least one of the slidable ratchets.

4. A hinge comprising in combination a first leaf having a hub with'a'fixed ratchetimounted therein, a second leaf having a second hub with a ratchet slidably but non-rotatably mounted therein, a pintle extending through said ratchets and having a reduced end extending through the slidable ratchet with a shoulder adjacent thereto, anut secured to azhub of one of the leaves and having means to engage and center said pintle, and means'operated by the nut to exert a pressure on the slidable ratchet, said slidable ratchet beingremovable on the removal of the pintle by engaging the said shoulder.

5. A. hinge comprising in combination a first leaf having a first hub, .a second leaf having a second hub, a fixed'ratchet in the first-hub, a-ratchet slidably but non-rotatably mounted in the second hub,- a spring bearingon the second ratchet, a washer bearing on the spring, the washer being non-rotatable but slidable in relation to the second hub, the washerbeing secured to the spring and the spring to the slidable ratchet, a pintle extending through said ratchets, and means engaging a hubof one of the leaves exerting pressure onthe washer, the washer, spring and slidable ratchet being removable and insertable as a unit.
