Specification of Letters Eatentf PaljBlltBfl July 25,

Application filed March 2, 1921. "Serial ll'o. 449,024.

To all whom it may concern:

Be it known that l, Gnonon VUILLE, a citizen of the United States, and a resident of Shelby, in the county of Ri hlund and State of Ohio haveinvented certain new and useful Improvements in Hinge Checks, of which the following is a specification.

My invention relates to hinge checks for double swinging doors, and a purpose of my invention is the provision of a hinge check which is operable to permit of the ready opening of the door in either direction,

maintaining the door in a 90 open position,

and automatically closing the door when moved from such angular position. Furthermore, my invention prov-ides a hinge check which includes fluid control means for the closing ofthe door, such means being operaole to e'ftectivel retard this closing action irrespective of the angle which the door occupies when it is released.

I will describe one form of hinge check embodying my invention and will then point out the, novel features thereof in claims. 4

In the accompanying drawings:

Figure 1 is a fragmentary view showing in side elevation a door frame and double swinging door having applied thereto one form of hinge check embodying my invention.

Figure 2 is a view showing in side elevation a finish plate adapted to be applied to the door for housing the hinge check.

Figure 3 is a vertical longitudinal sectional view of the hinge check shown in Figure 1 with the parts thereof in the proper positions when the door is in open position.

Figure t is a detailed perspective view of the stationary sleeve embodied in the hinge check shown in. Figures 1 and 2.

Figure 5 is a View similar to Figure 4;

showing the rotatable cam embodied in the hinge check. v

Figure 6 1s a view similar to Figure 5 showing the reciprocating cam embodied in Figure 10 is a transverse sectional view taken on the line 10-10 of Figure 3.

Similar reference characters refer to sinrilar parts in each of the several views.

Referring specifically to the drawings and particularly to Figure 8, the hinge check in its present embodiment comprises a floor plate P upon which is sustained a sleeve which th'readedly receives the lower end of a barrel B. In superimposed relation with respect to the sleeve 55 is a rotatable cam K, and" interposed between the confronting edges of the sleeve and ca m are roller beari-n'gs 15 mounted in raceways formed in the edges of the sleeve and cam. The earn K is provided with laterally disposed arms 1-6 that are adapted to be secured to the door so that the cam bodily rotates with the door when thelatter is swung to open position in either direction. Arranged above the cam K is a reciprocating cam K, the lower edge of the cam K and the upper edge of the cam K being so formed as to provide helical grooves '17 arranged in quadruple in oppositely disposed intersecting pairs, as shown in Figures 5 and 6. Each grooved helix -extends through a quadrant to a point of intersection to an adjacent helix, the twoadjacent helices being at opposite inclinations. The lower walls of the grooves on the upper edges of' the cam K are at their upper point of intersection notched as indicated at 1'7 to provide a resting place for the lower point of intersection of the upper walls of the grooves, the reciprocating cam K occupying this position in the open po sition of the door whereby the door may be retained in. such open position. The upper edge of the reciprocating cam K is formed with an intersecting pair of helical cam sur faces 1'8 which are adapted to be engaged by a roller 19 (Figure 1) adapted to 'be car'- ried by the door for restricting the upward movement of the camK. These cam sur faces 18 have their lower ends disposed below the upper edge of the remaining portion of the ca m so as to provide shoulders 20 against which the roller 19 is adapted to abut when the door is in either of, its extreme positions.

As shown in Figure 3, the barrel B is loosely embraced by the cams K and K" and serve to sustain these cams in position to permit of their reciprocating and rotary motions. Interiorly of the barrel B is arranged a container C which is formed at its lower end with a threaded collar 21 that has threaded engagement with the walls of a suitable opening formed in the floor plate P. As shown in Figure 7, this container C is formed ofa main tubular section 22 and a top collar section 23 which is threadedly associated with the main section and between which is interposed a packing disc 24: that serves to hermetically seal the upper end of the container. Within the lower end of the container C is positioned a pair of integrally formed cylinders D and D having their lower or closed ends formed with a screw plug 25 which threadedly engages the reduced end of tie container. The plug is formed with tool receiving recesses 25 to permit of the rotation of the plug within the container and to thereby effect a restricted vertical adjustment of the cylinders D and D for a purpose which will be hereinafter described. As shown in Figure 8, the cylinders D and D are formed adjacent their lower ends with

ports

26 and 26*, respectively, controlled by a cam valve 27 .formed on the end of a screw threaded spindle 28 threadedly fitted in the container in the manner clearly shown in Figures 7 and 9. These ports 26 and 2-6 are in communication with a channel 29 formed on the periphery of the casing including the cylinders D and D, such channel in turn effecting communication between the upper part of the container and the ports so that with the valve 27 in open position any fluid contained in the cylinders will be free to pass into the container at a point above the cylinders. As shown in Figures 8 and 9, the cylinder D is formed intermediate its ends with a port 30 which communicates with a channel 31 that extends to the upper end of the cylinder and thus forms communication between the upper part of the container and the cylinder D for a purpose which will be hereinafter described.

Adapted to work within the cylinders D and D are pistons T and T, respectively, formed on the lower ends of

rods

32 and 33 which are slidably fitted within suitable openings formed in the collar section 23. The rods in turn are rigidly connected to a guide plunger G which as shown in Figure 8 is slidably fitted within a thickened portion 33 of the barrel B. The upper end of the plunger G is formed with a head 34 of reduced diameter that is adapted to fit within the lower end of the coiled expansible spring 35 mounted within the upper portion of the barrel B and confined therein by means of a screw plug 36. The plunger is bored transversely to receive a pin 37 which extends not only through the plunger but through elongated slots 38 formed in the barrel B as shown in Figures 8 and. 10. The opposite ends of the pin 37 are fixed within the reciprocating cam K so that when vertically moved, such movement will be imparted to the plunger G.

In the application of the hinge check to a door as shown in Figure 1, the inner edge of the door adjacent its lower end is recessed as indicated at 39 to accommodate the hinge check. The walls of this recess are covered by a metal strap 40 which carries the roller 19 and a bearing pin 41 which works in a suitable recess 42 formed in the plug 36. The lower end of the hinge check is secured to the floor by means of a floor plate P, suitable fastening members Xtending through the plate in the manner shown. The arm 16 is secured to the opposite sides of the door. while completely enclosing the hinge check is a housing H provided along its vertical edges with ears that receive fastening members for securing it in housing position with respect to the hinge check. For the proper operation of the hinge check, the upper inner corner of the door is provided with an angle plate 43 having a bearing 43 in which works a bearing pin i-l carried by an angle plate 45 secured to the door casing. By this arrangement it will be seen that proper supporting means is formed for the upper end of the door to insure of the desired swinging movement.

The operation of the hinge check is as follows lVith the door in the position shown in Figure 1, the roller 19 is at the apex or point of intersection of the cam surface 18, and when the door is swung in either direction to open position the reciprocating cam K is moved upwardly ot the barrel B by virtue of the reaction of the walls of the helical grooves 17 of the cams K and K, the lower point of intersection of the upper walls of the grooves reposing within the recesses l7 when the door has reached a 90 position. By virtue of this upward movement of the cam K, the guide plunger G is elevated against the tension of the spring 35 so as to effect a corresponding movement of the pistons T and T. The container C is adapted to be partially filled with merrury so that upon upward movement of the pistons when opening the door such mercury will be drawn into the cylinders through the

ports

26 and 26 so that with the door in a 90 open position the cylinders are completely filled with mercury and the lower points of intersection of the upper walls of the grooves 17 repose within the recesses 17 to temporarily maintain the door in open position. lVhen it is desired to close the door a slight movement of the door will remove the points or the cam K from the recesses 1? to allow of the functioning ofthe spring 35 in deoressing the plunger and the cam K therehy causing the latter to coact with the cam K in returning the door to closed position. During this movement, the pistons T and T descend into the cylinders D and D thus ejecting the mercury from the cylinders into the container. However, be?

cause of the restricted .areaof-the ports 26' gradual and uniform closing of the door,

This movement can be readily controlled by an adjustment of the valve 27 which neces' sarily controls the [low ofmercuryi rom the" cylinders.

Should the door he openedito any position less than a right angle position, and then released, there would be an insuflicient quan tity of mercury within thecylinders to effect and retard the closing of the door. However, in order to prevent such an act-ion, the port 30- and thechannel 81 are provided which, because of their arrangement with relation.

to the cylinder D, permitsot the-rapid in flux of mercury into this cylinder so that when the piston is moved outwardly to any distance greater than half of the length of the cylinders, the port 30 will be opened thus allowing mercury to flow into the cylinder from the container. It will therefore be seen that a partial opening of the door will effect a partial filling of the cylinder D with mercury, it having been found in practice that the partial filling of this one cylinder is suflicicnt to retard the closing movement of the door when the latter is moved to any position less than a right angular position.
