COMBINED SPRING-HINGE AND DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 424,614, dated April 1, 1890.

Application led December 20, 1889. Serial No. 334,433. (No model.)

To all whom t 17m/y concern:

Be it known that 1, JAMES WILLARD Mon- RIs, a citizen of the United States, residing at New York city, in the county and State of New York, have invented a new and useful Improvement in an Automatic Combined Springllinge and Door-Check, of which the following is a specification.

The main object of my invention is to simplify the'con struction, and thereby reduce the size and lessen the cost of the combined springhinge and door-check which is the subject of an application iiled by me September 9, 1.889, Serial No. 323,419.

A further object of my invention is to produce a combined spring-hinge and door-check which may be converted into a simple hinge without the removal of any of the parts by simply throwing the spring and checking mechanism out of action.

In my application above referred to the opening of the hinge tends to rotate the hingepintle relatively to the cylinder and to the inclined planes, whereby through such relative rotary movement the hinge pintle is lifted. The construction. shown to effect this in that application required the extending of the cylinder of the dash-pot below the hingeleaves and the formation of the inclined planes on the same leaf as the cylinder, thus increasing the size and cost of manufacture of the hingeL In my present invention the hinge-pintle does notl rotate relatively to the cylinder and the inclined planes are not on the same hingeleaf as the cylindenv By this construction I am enabled to lessen the size and cost of the hinge, as the cylinder or dash-pot thereof may be formed and arranged adjacent to and not below the hinge-leaves, and the lifting of the pintle may be eifected directly relatively to the cylinder, which is a desirable feature, tending to economy in size and cost In the simple form of my present invention the hinge-pintle is prevented from rotating relatively to the cylinder by being squared or angularly formed for a portion of its length and caused to pass through a square or correspondingly-angular hole cut in the cylinder of the hinge. In the convertible form the hin ge-pintle is squared, as before, but instead of being caused to pass through a square hole in the top of the cylinder it is caused to pass through a square hole in a part which, when a simple acting hinge is desired, may be readily arranged to turn with respect to the cylinder, so as to oppose no resistance to the rotation of the pintle, but which may be locked to prevent the rotation of the pintle relatively to the cylinder when a 'combined spring-hinge and door-check is desired.

In both forms of my present hinge the lifting of the pintle is effected by the opening of the hinge directly, either by forcing an inclined plane under a projection of the pintle when the cylinder is stationary or by forcing the pintle directly up the inclined pla-ne when the cylinder moves.

Of course it will be understood that it is immaterial to the operation of the device how it is applied-th at is, whether the leaf carrying the cylinder is the moving leaf and the leaf .carrying the inclines the stationary leaf, or vice versa.

In the accompanying drawings, forming a part of this specification, Figure 1 is an elevation, partially in section, of a-combined spring-hinge and door-check embodying my invention. Fig. 2 is an elevation, partially in section, of a convertible spring-hinge and door-check. Fig. 3 is a vertical section of a portion of the device of Fig. 2, certain of the parts being in elevation. Fig. a is a crosssection taken on the plane of the line et 4, Fig. 3, with ,the anti-friction balls removed. Fig. 5 is a cross-section taken on the plane of the lines 5 5, Fig. l; and Fig. G is a cross-section of the cylinder of the dash-pot, taken on the plane of the line 6 G, Figs. 1 and 2.

As shown in the drawings, A is the moving leaf of the hinge, B the stationary leaf, and C t-hc pintle, which combines the two parts of the hinge.

The moving leaf of the hinge is provided with a socket D, cored to receive the pintle and provided with spiral grooves E and E', adapted to receive rollers F F', carried by said pintle.

The stationary leaf of the hinge is provided i with the socket, knuckle, or cylinder G, which receives the pintle, the coiled spring' II, and the supply of fluid which acts as the cushion.

In Fig. 1 the socket or knuckle D is supported upon the cylinder G, as shown, and to IOO reduce the friction between those parts antifriction bearing-balls I are introduced into the circular groove formed by matching' the semicircular channels in each part.

The pintle C is squared for a portion of its length and passes through a square hole in the top of the cylinder G in Fig. l., whereby it is prevented from turning relatively to said cylinder. At, its endvthe pintle is provided with a head J, having passages J therein. A

valve K, surrounding a collar L, is afforded a spring-seat by the coiled spring L and between the head J and the upper end of the cylinder the'spring H is coiled around thev pintle. For the purpose of combining the head J and parts below it with the pintle I' form a shoulder on (the pintle, as shown, and turn ascrew-thread on the reduced portion- The head J vand collar L 4are internally screw-threaded and are leasily adjusted to place, the collar L acting as a The spring L and' below the shoulder.

jam-'nut for the head. valve K are held in place by the iiange L2 of the collar.

at c yo2 o3 o4, Fig. e. r

I prefer to mount the rollers F F on thel pintle C by passing a screw O through each,

countersinking the heads in the rollers, the

screws being of such length that their ends will abut at the center line of the pintle. -A screw P is then inserted from the top of the 'pintle and 'passed through the ends of each of the `screws O, as shown at Fig. 5. By this construction the rollers may be readily com. 'Y bined with "the pintle, the screw P prevent-v ing the turningof screws O, wherebythe parts will remain in place.

The operation of the par-ts above described j is as follows: Preferably the rollers F F are so Aarranged with reference to the spiral 1 grooves E and E that when the door is closed they will be raised somewhat from the bottom thereof. The object of this is to provide room for the expansion of t-he closing-spring H to effect the latching of the door aft-er the door Fluid willf is brought to the closed position. be `-supplied to the cylinder, so as to fill or nearly fill the same. the lower wall of the grooves E and E' will actas wedges, and will, in proportion to the extent they are forced under the rollers F F',

lift them and the pintle with themA By carrying the grooves nearly around the section. or knuckle D, which is preferably circulan' the door may be opened to more than ninety` degrees. The lifting of the pintle C compresses the spring H, which, when the door is released, :acts to force the pintle to the bot-1 tom of the cylinder G. During `the upwardr movement of the head J the passages J A therein will remain open until the bottoln of the head has just passed the lower end of the The fluid, which i channels C', C2, 'Cand C4. up to this point iiowed through the passages J', will now flow aroundthe periphery of the head in the said channels freely, and the The cylinder G iis formed with' channels for a portion of its length, as showny On opening the doory -around the periphery of the piston-head in the more restricted space which now occurs,

between the cylinder andwhead below the channels C', 85e. By a proper proportioning of the parts the check may be effected fat any desired point in the closing movemen't'of the door.

The convertible form of hinge is 'substantially similar in construction and mode `of,

operation to the simple vform above described, differing from it, however, in the following particulars: Between the section D and cylinder G a steel ring Q is interposed-,said ring being provided with an annular flange X, which `enters 'a circular opening in the head of the cylinder G, whereby said ringis seated so that it may turn freely whenl unlocked.

Said ring is also provided with'a semicircu'la'r.

groove corresponding with `the groove in the sect-ion D. Anti-friction bearing-balls are 1nserted between these two parts in the circular groove, as was done between the section D and cylinder. On the periphery of this steel ring a notch R and hole S are cut, and its'cen-ter is IOO formed Vwith a square hole'to Vreceive theYYY square portion 'of the pintle C. Upon a lug T, projecting from the cylinder, a dog U is pivoted in such position as to adapt a tooth U on its end to enter the notch R and lock the ring Q from rotating. AA rspring U2L 'acts to throw and hold the tooth in v,its notch. The hole S is adaptedto receive-a pin or other implement by which the ring may be turned IIO when effecting the engagement or disengagch ment of the tooth U and -notch R. j l

It will be obvious that when the steel ring is locked from tu-rning by the dog U the lopening of the door will effect the lifting of the pintle and the action will be the `same as described for the simple form of hinge; butV when the steel ring is free to turn by reason of the tooth on the Adogbeing out ofthe notch the result will be that the pintle C will be' turned 4relatively to the cylinder and not lifted, and of course the spring and checking mechanisms will not be operated. j

In operation at the lmoment the check is effected there is a tendency for the hinge leaves-to separate vertically. This mayreadi-ly v be provided for in several ways-eas, for in*- stance, by locating my device on a door be tween two ordinary hinges, or by placing two offmy devices on the same door, one with -t-he cylinder stationary and vthe other with the cylinder movable.
