DOOR CHECK AND CLOSER.

Application led July 9, 1915.

To all whom t may concern:

Be it known that lf, CHARLES V. BERRY, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Door Checks and Closers; and l do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is a door check and closer which may be economically applied to a double acting door, as well as a single acting door.

A purpose of this invention is to provide an improved hinge for doors and the like, wherein the door closing, as well as the door checking mechanism may be included in a hinge element, the parts of the door closing mechanism acting upon Huid conlined within the hinged casing to serve as means to check the closing of the door.

rlhe arrangement is such that the 'door cannot be moved toward its closed position more rapidly than the fluid and a guiding element will permit, thereby preventing the door from closing too rapidly. Furthermore, the closed position of the door, with relation to its frame, may be readily adjusted without removing the door from its support or to any particular position. The control of the operation of the oil checking mechanism may be likewise effected by means exterior of the door and its hinge.

Further advantages will appear from the following detail description of the invention, taken in connection with the drawings.

While a preferred embodiment of the invention is `illustrated in the accompanying drawings, it is to be understood that the construction therein set forth is for the purposes of illustration only, and not as defining the limits of the invention.

In the drawings: Figure 1 is a vertical sectional view disclosing the hinge elements as arranged when the door is in its closed position. Fig. 2 is a side elevation of the casing for the hinge. Fig. 3 is a vertical sectional view through the tubular piston stem,`with the piston in position thereon. Fig. 4 is a plan view, of the upper tang. Fig. 5 is a Plan view of the supporting and adjusting block. Fig. 6 is a vertical sec'- tional view disclosing the position of the coacting blocks when the door has been turned Specification of Letters Patent.

from its closed position. Fig 7 is a plan view of the floor plate. Fig. 8 is an enlarged vertical sectional view through the base cam block. Fig. 9 is a side elevation of the upper tang. Fig. 10 is a side elevation o-f the supporting and adjusting block. Fig. l1 is a front elevation of the shaft and worm which coperates with the block of Fig. 10.

Referring more particularly to the embodiment of the invention disclosed in the drawings, the working members may be concealed by a suitable shield 1. The door is preferably cut away at the lower rear portion to provide space in the combined hinge and check, the hinge and check mechanism being supported on the door by an vupper tang indicated at 2 and a lower tang indicated at 3, which tangs are secured to the door by any suitable means. The upper tang is shown provided with a horizontal member 4 and a depending collar 5. Within the depending collar ,may be formed an angular aperture 6 within which may be positioned an angle wear plate 7 which may be adjustably mounted within the aperture 6 by any suitable means such as the screw 8. The upper portion of this horizontal plate 4 may be recessed to receive a cap plate 9 which may be secured in any suitable manner to .the tang plate member 4 either by pressing plate 9 into position or screw threading the edges thereof.

The lower tang 3 may be provided with an upstanding threaded projection 10 to receive a tubular casing 11. This projection 10 may be provided with a central aperture through which may extend a supporting post 12 of the base block 13. The upstanding member 10 may be recessed to receive suitable packing` 14 to be retained in position by a packing nut 15. The tubular casing 11 is adapted to receive a suitable fluid checking medium, such as oil, to be vpoured through the aperture 6 of the upper tang and secured in the tubular casing 11 by means of the cap plate 9 and the packing and nut 14, 15 respectively.

Within the tubular casing 11 is positioned a tubular piston stem 16, the upper end of which is shown rectangular as at 17 to engage the rectangular aperture 6 of the upper tang 2 to permit of reciprocating movement of the stem with relation to the tang 2, but prevent rotative movement of said stem. rlhe plate 7 within the aperture 6 is designed to engage a plurality of faces of the angular portion of the stem 16, and the adjusting screw 8 is designed to take up the wear on the angular part of the stem. Vithin the lower portion of the stem 16 is secured a piston indicated at 18 and which may be secured to the stem in any suitable manner. This piston is provided with a longitudinal restricted aperture 19 which registers with the passage 20 through the stem 16. This aperture19 may be provided with a suitable valve, shown as a ball 21, which is designed to engage the valve seat 22 when the fluid in the tubular casing 11 is forced upwardly through the passage 19 to check the flow of fiuid. The ball 21 may be limited in its downward movement by any suitable means, such as a pin 23. The piston 18 is shown provided with an arcuate groove indicated at 24 which extends from a point near the base of the piston, upwardly toward one side of the stem 2O and thence to a point 25, and thence downwardly to the other side near the base of the piston. If desired, two of these grooves 24 may bc provided on the stem 16.

Secured to the stem 16 is a riding block 26 which is shown provided with a cam surface 27, the face of the cam being shown substantially concentric with the edge of the groove 24.` This riding block 26 is designed to engage and coperate with the cam surface 28 of the base block 13, as shown in Figs. 1 and 6; The base block 13 may be provided with a lug 29, which may be an adjustable element suchas a screw to engage the arcuate groove 24 of the reciprocating piston. The screw lug 29 coperates with the groove 24 to limit the closing movement of the door, thereby serving as one ofl the checking means.

The base block 13 -is shown provided with a chamber 30 to receive the piston plunger 18; This chamber 30 is designed to contain the checking fluid, such asv oil. The base block 13 and its post 12 are provided with passages 31 and 32 which are joined at 33 near the base of the post. The passage 31 is designed to conduct the fluid from the chamber 30, around the juncture 33, which serves as a valve seat, thence through the passage 32 and upwardly to a transverse aperture 34.v The oil flowing upwardly at 34 may then pass over to the rear of the piston plunger 18V at its cut away portion,

to be positioned flush with the floor.

block 39 and to be secured thereto by the passage of a pin, shown as a tapered pin 40, which passes through the block 39 and the post 12. This block 39 may be provided with a bushing 41 adapted to house a part of the packing nut 15, and lalso a depending section 42 which is adapted to enter an aperture 43 of a floor plate 44 which is designed The blocl 39 is shown provided with a plurality of arms 45, 46, and withinthe space 47 between the arms 45, 46 there may be positioned a worm 48 mounted upon a shaft 49 which is adapted to be j ournaled in the arms 45 and 46. The shaft 49 is shown provided with means, such as the slots 50, for rotating the shaft and its worm 48. This worm is designed to engage a slot 51 in the floor plate for the purpose of adjusting the closed position of the door with relation to its frame. It is to be understood that any desired number of slots 51 may be provided in the floor plate 44, although only one of these slots is illustrated in the drawings. The plunger stem 16 may be provided with an aperture 52 to permit fluid contained within the tubular portion 20 to flow exterior of the stem 16 to lubricate the parts of the hinge. A suitable resilient element, shown as a helical spring 53, may be positioned between the shoulder'formed by the riding cam block 26 and the end of the depending section 5` of the upper tang, to resist the upward movement of the piston stem 16, which serves to return the door to its closed position.

It will be observed that when the door is moved to an open position, the fluid in the chamber 2O will be permitted to iiow freely toward chamber 30. As the door is moved to its closed position through the impulse of the resilient element 53, the plunger 18 compressesthe fiuid in chamber 30 and forces the fluid outwardly through passages'31 and 32 toward the rearv of the piston plunger 19, the oil endeavoring `to find its way back to the tube 20. The return movement of the door is also limited by the lug 29 engaging the arcuate groove 24. The passage of fluid through the apertures 31 and 32 may be controlled by the screw valve 36 exterior of the door casing to regulate the return movement of the door, and the return position of the door may be controlled by rotating the shaft 49 exterior of the door mechanism, as illustrated in Figs. 1 and 2.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
