DOOR CHEVCK AND CLOSER.

Specification o'f Letters Patent.

Patented June 28, 1910.

To all whom it may concern.;

Be it known that I, JOSEPH CHARLES RE- GAN,-'of Stamford, in the county of Fairfield. and State of Connecticut, have invented certain new and useful Improvements in Door Checks and Closers; and I 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.

My invention relates to an improvement in door checks and closers and particularly yto that type which are set in the sill of the door and form the lower hinge for the latter, 'the upper end of the door bein supported at its upper end by a pin orstu projecting downwardl into a socket carried by the upper edge o the door, and it consists in the parts and combinations lof parts as will be more fully explained and pointed out inthe claims.

y In the accompanying drawings, Figure is a view in plan of my improved check and closer the cover plate being removed.v Fig. 2 is a top plan view of the finish cover plate. Fig.. 3` is aview in longitudinal section on the line L -B of Fig; `1. Fig. 4 -is a view in transverse section'on theline -Cl-D of Fig. 3. Fig. 5 is a view in transverse section on the line E and F 4of Fig. 1. Fig. 6 is a similar view on the line G-H of Fig. 1

- land Fig. 7 is a view of the operative parts removed from the casing.y

. ,1 represents a casing made of a single casting, closed at the bottom, sides and ends and open at the top. This casing is deeper Lat its rear end or the end carrying the spindle, than at its other end, and is closed by a two part cover 2 and 3 the former of which is provided with an opening or bearing for the passage ofthe spindle 4, suitable packlng 5 being provided for preventing the liquid contained within the casing from esca ing up around the'spindle. This spindler 4 orms the lower hinge of the door andis mounted at its lower end in the recessed seat 6 formed in the enlarged ,part' of ,casing 1,

andis yprovided with a double crank 7 carrying twoanti-friction rollers v8, `which latter` are located on opposite sides of thespindle. 4, as shown in Fig. 1, and bear against t-he end of the `yoke. 9. The head of the oke extends transversely of the Casin an beiPy-ond both anti-friction rollers 8, s as tobe 10 which are in effect guides for the' yoke. y

These rods 10 are secured to the members 9a of the yoke 9 by the pins or screws 11, eX- tend lengthwise the casing and terminate at their front ends in pockets 12 formed in the frame 13. i

Mounted on the rods 10 intermediate the frame 13 and the nuts 11, are the springs 15, the rear ends of which bear against the frame 13 and their oppositeV ends against the nuts 14. These nuts are threaded internally and are mounted on threaded sections of the rods 10, so that by moving the nuts toward or away from the springs 15,

the tension of the latter may be increased rest, 4and against the one roller when the door is wholly or` partly opened. The yoke is also. guided in its movement by the rear' end 13'al of frame 13, whichrests between the two forwardly extending members 9a of the yoke, and prevents anyy lateral or swinging movement of vthe latter. This frame 13 is pivotally mounted at its rear end in front of the spindle on the pintles 16 and.l7, the former. of whichis integral with and projects upwardly from the frame and is mounted in a.v seat 18 integral with and projecting downwardl from section 3 of thecover, while the pintle 17 is integral with the liquid cylinder .19 and rests in a recessed seat 20 formed in the floor'or bottom of the casing. The two pintles 16 and 17 are "in the same vertical plane, and constitute the v axis or center on which frame 13 turns, andi asgthe cylinder 19 is integral with the frame,

it necessarilyfollows that when the frame 13 is adjusted as will be hereinafter' described, the cylinder will be correspondingly moved. Thecylinder, is-of greaterv width thanthe frame 13, and is in a plane below the frame and within the enlar ed or deeper part ofthe casing. 1 as clearly s own in Fig. 3. The front end of the frame 13 isfprovided at its` side edges with the laterally projecting ears 21 the latter havino' slots22 curved in the arcs of a circle coincident with the centers 17 and 18 on which the Vframe turns. These ears 21 rest on the shoulders 23 integral with the casing 1, and lare secured thereto by the clamping screws 24, which as shown in Fig. 6 pass through section 3 of the cover.

With checks of this ty e it' is a difficult matter to set them to holgd the door in its proper position. With my improvement, if the check is set in its floor mortise out of line, it can be adjusted within a` `reasonable range, which should be suflicient in all cases where ordinary care is exercised in setting the check, by simply loosening the screws 24 and moving frame 13 to the right or left as the case may be. This moves the cylinder and also the spindle and necessarily the door carried by the spindle. When properly adjusted it is then secured by tightening up the screws 24.

Mounted in the cylinder 19 is the piston 25 connected by rod 26 with the crank pin 27 carried'by the crank arms 28 integral with the spindle 4. These crank arms are in a plane below the cranks 7, and as the spindle is turned by opening or closing the door, the cranks 28 operate to move the piston away from or toward the closed end of the cylinder. rlhis piston is provided adjacent to its lower edge with a fluid escape port 29 inwhich is mounted a ball valve 30, the latter being limited in its movement away from its seat by' the pin 31, which is also the attaching means for the rod 26. As the piston 25 moves toward the open end of .the cylinderV 19, as in opening the door, the valve 30 moves away from its seat and permits the fluid within the casing to freely pass through the piston to the front thereot. As the door closes, the valve will be forced by theA pressure of the liquid against its seat and thus prevent the escape of any. liquid through the piston. The checking liquid in front of the piston, escapes through the two ports 32 and 33, located one in front of the other, the port 33 being in front of port 32. Each port 32 and 33 has lateral ports 35 communicating with the interior of the casing, and each is also controlled by a screw valve 34 which extends above the top of frame 13,. and are accessible from the top when cover section 3 is removed. By means of these two valves the tlow of liquid from the piston chamber or cylinder may be regulated as desired. At the commencement of the closing action, both valves can be adjusted to permit a large volume of liquid to escape, but after thepiston reaches the port 33 and covers same, the escape of liquid will then be restricted to the one port 32 which necessarily checks the closin movement, and which can be regulated y its valve 31 for comnormallyV acting together, and the cylinder is in the'same chamber with the springs but below them, so that `the vchecking iiuid whatever it may be, is free to circulatein the spring chamber, but by locating the port in the piston, as near as possible to the bottom of the latter, the check will=operate with comparatively a small charge of liquid.

closer is as follows: In the drawing the 85 rlhe general operation of this check and parts are shown in their normal position as when the door is closed. lf now, the door be opened in a direction indicated by the arrow in F ig. 1, the revolution of the spindle 4 causes one friction roller 8 to bear against compressingy both springs 15. The turning of the spindle 4 also withdraws piston 25, until rod 126 brings up against thefspindle ,.4 which will occur when the door is open about 90 degrees, thus limiting the turning lthe yoke 9 and move same forwardly thus movement of the spindle, and acting as a natural stop. This withdrawal of the piston permits the liquid to flow through port 29" to the front of the piston head, and acts in the usualmanner, against the piston, to check Ithe closing movement of. the door. When the door is released, the action of the springs 15 tends to close it, and the liquid loofa confined between the head of the piston-and the closed end of the cylinder, will at firstI liow readily through both ports 32 and 33, and then aspreviously described, more slowly throughthe port 32 as'the first `is covered by the piston. "lf the door be opened in the opposite direction the same actionl will occur, through the other roller 8 engaging yoke 9. In order to provide for the change in adjustment or" the screw valves 34, l have provided the cover plate 3, and also the inish plate 35 with a hole for the screw cap 36 which is screwed into cover 3 and when removed, exposes the heads of the two screw valves. lf after the device has been `set infits floor mortise, it is found to i the parts causes the spindle 4 to turn and thus bring the edge of the door into its the removal of proper closed ositionl with relation to the door jamb. After the parts have been properly adjusted the screws 24 are again tightened andthe device ready for use.

By removing the cover plate, and swinging the door to one side, the crank pin 27 which is screwed into the lower arm of the piston crank, will be exposed and can be removed, thus permitting of the removal of the entire operative mechanism except the spindle for examination.

It is evident: that many slight changes might be resorted to in the relative arrangement of parts shown and'described withoutdeparting from 'the spirit and scope of my invention hence I would have it understood that I do not wish to confine myself to the exact construction and arrangement of parts shown and described, but,

Having fully described my invention wha I claim as new and desire to secure by Letters-Patent, is
