ADDISON D. LODGE, OF VANDALIA, OHIO.

Doon-CLOSER.

SPECIFICATION forming part of Letters Patent No. 481,798, dated August 30, 1892.

Application filed May 18, 1892. Serial IIa/133.415. (No model.)

To all whom t may concern..-

Be it known that I, ADDISON D. LODGE, a citizen of the United States, residing at Vandalia, in the county of Montgomery and State of Ohio, have invented certain 'new and useful Improvements in Door-Olosers; 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.

This invention relates to builders hard- Ware, and more especially to that class thereof known as door-closers and the object of the same is to produce an improved device capable of holding the door constantly open or closing it and adapted to be removed from the door instantly when desired and without the use of tools.

To this end the invention consists in a spring carried by the casing and of certain peculiar construction, a staple on the door, a slotted bar detachably connected with such staple and passing under the spring, and a rod pivoted in the slot of the bar and having a notch detachably connecting with said spring, the

whole being of the general and speciiio construction hereinafter more fully described and claimed, and as illustrated on the drawings, Wherein- Figure 1 is a front elevation of this device as applied to a door, the latter being closed. Fig. 2 is a horizontal section on the line 2 2, showing in full lines the parts in position with the pin which prevents the spring holding the door open and in dotted lines the `parts with such pin removed and the spring as holding the door open. Fig. Sis a vertical section on the line 3 3 of Fig. 1. Fig. 4 is a perspective detail of the bar and rod.

Referring to the said drawings, the letter O designates a casing, and D a door mounted therein upon hinges H, which may be ot' any approved pattern, and one of which preferably carries a staple 1, forming a part of this device.

F is a frame, which I have shown as secured to the casing O; but I desire to be now understood that the frame may be carried by the door and the staple 1 bythe casing, thereby eiiecting an entire change of the position of this spring, but Without in the least altering its operation. The said frame preferably comprises two horizontal members 2 and a vertical strip 3, all secured to a plate 4, which is fastened by screws 5 to the casing. The plate 4 also carries a U-shaped bracket 6, and between each outturned end 7 of this bracket and the adjacent members 2 are arranged vertical and aligned pins 8,whose inner ends are separated the Width of the bracket. 9 are levers pivotally mounted' at their inner ends on these pins adjacent the members 2, and their outer ends engage teeth lO in the innerl faces of the members, for a purpose to appear hereinafter.

11 are arms having cylindrical feet 12, which are pivotally mounted on the pins outside the outturned ends '7. A piece of spring-Wire is also provided, Whose center 14 forms a loop which spans the space between the outer ends of the arms 11 and enters notches 13 in said outer ends, on each side of which center the arm of the loop then coils, as at 15, around the feet 12, and at its end 16 bends over the lever 9. Obviously when these levers 9 are adjusted in the teeth 10 the force of the spring A will be graduated, as desired..

2O is a barwhose inner end is notched vertically, as at 2l, so as to detachably engage the staple 1, and whose outer end is notched, as at 22, and has a roller 23, journaled on a vertical ring therein and adapted to travel over the plate 4. The body of this bar has a long horizontal slot 24, which is intersected by a removably vertical pin 25, and in its outer face the bar also may have notches 26.

27 is a rod mounted on a vertical pivot-pin 28 within and near the inner end of the slot 24, and the outer end of this rod has a notch 29, in which the center 14 of the spring detachably rests. v

The parts of this improved spring being applied to the door and its casing, it will be ob vious, as seen in the drawings, that when the door is opened the bar 2O is driven through the bracket 6, the roller 23 traveling on the plate 4, and during such movement the pivoted pin 28 causes the rod 27 to push on the spring and turn the two arms 11 to the rear, so that the coils 15 are wound up and power stored therein. Obviously the adjustment of the levers 9 over the teeth 10 will increase or decrease such power,

ICO

as may be necessary, lWhen the door is released, the stored power forces it quickly shut. lVhen it is desired to remove this device, as when the door spring is not wanted, the spring is borne outwardly by hand until its center 14 disengages the notch 29, and the notch 21 of the bar is also disengaged from the staple 1, and the bar and rod entirely removed.

The peculiar construction of this device effects an additional function, as follows: In the operation of opening the door, while the inner end of the bar 2O moves around the hinge-pintles, its outer end, having the roller 23, travels in a straight line over the plate 4, and hence the center of the bar is temporarily raised from the strip 3. lVhen, however, the door is nearly opened and the staple bears the inner end of the bar again in toward the casing, the body of the bar strikes upon this strip 3, and the further opening of the door raises the roller 23 entirely off the plate 4, the bar 20 turning over the strip 3 as a fulcrum, as seen in Fig. 2. If at this time the removable pin 25 is in place, it will strike against the rear edge of the rod 27, as seen in full lines in Fig. 2, and will check the outward movement of the door before the pivot-pin 28 passes beyond the straight line between the staple 1 and the center 14 of the spring, and hence the door when released will close automatically; but if itis desired that the door shall stay open of its own accord this pin 25 is withdrawn, and then when the door is opened, as above described, the slot 24 of the bar is unimpeded, and this movement of the bar over the strip 3 as a fulcrum is allowed to continue until the pivot-pin 2S passes beyond a straight line between the staple 1 and the center 14 of the spring, thereby holding the door open,while the notches 26 in the bar 2O rest under the center of the spring, as seen in dotted lines in Fig. 2. Hence the mere removal or insertion of the pin 25 changes the entire operation of the device, and, as above stated, the device can be rendered totally inoperative by removing the bar and rod.

The parts are preferably of metal of any suitable shape, size, and finish, and I do not confine myself to the exact details of construction, as considerable change can be made therein without departing from the spirit of my invention. For instance, the dotted lines in Fig. 1 show how this device is formed with the hinge H, in which case the member bearing the staple 1 will be secured to the door, and the other member bearing the frame F will be secured to the casing, (or vice versa,) the parts being made of cast or stamped sheet metal, and if of the latter the strip 3 being formed by a wrinkle in the body of the metal. The pintle which connects the leaves of the hinge is preferably made in the forni of a drop-pin, which is passed from above through the aligned eyes of the two leaves, and hence to unhinge the door ali that is necessary is to remove these two pins.
