DOOR, SCREEN, OR CURTAIN.

SPECIFICATION forming part of Letters Patent No. 786,841, dated April 11, 1905.

Application filed November 5, 1904. Serial No. 231,595-

To all whom, it may concern:

Be it known that I, GEORGE. J. REcoRD, a.

citizen of the United States, residing at Conneaut, in the county of Ashtabula and State of Ohio, have invented certain newand-useful Improvements in Doors, Screens, or Curtains; and 1 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 an improvement on the subject-matter of Letters Patent No. 768,693,

I granted to me August 80, 1904, and of application, Serial No. 221,142, filed August 17 1904:. Its chief objects are to. adapt the door or screen more perfectly to be used without change in or damage to the floor or doorframe, while permitting the opening, closing, and secure locking of the said door, to facilitate and perfect the fitting of the door in its frame with adjustment to greater or less width of doorway or irregularity in its form, and generally to improve the efliciency and durability of the door or screen and make it more suitable to fine surfaces and costly apartments.

To these ends my invention consists in the construction and combination of parts hereinafter more particularly set forth and claimed.

In the accompanying drawings, Figure 1 represents a front elevation of a door-section embodying-my invention expanded. Fig. 2 represents a similar view of the same partly contracted. Fig. 3 represents a view similar to Fig. 1 of a modification. Fig. 4 represents a detail side elevation of the casterand its bar with proximate parts; and Fig. 5 represents a front elevation of the bolt and proximate parts broken away at one point, the withdrawn position being shown in dotted lines.

A designates one of the two corresponding sections which make up aldoor or screen embodying my invention. If used alone, it becomes an entire door or screen. It has by preference two spring-rollers B and two flexible sheets a, constituting the body of the door, arranged as shown in the said application, inclosing the lazy-tong bars C, but may said strips or uprights.

laZy-tong'bars is hinged at its inner end to the said middle strip or upright bar'F and at its upper end to one of the said end strips or uprights A or A The general operation of the door-section or door is as stated in the said patent and application, and of course it is practicable to use a single continuous series of lazy-tong bars, as shown in'Fig. 4, instead of each of the divided series above referred to.

Between strips or uprights A and F, also A and F, are lock-bars D, arranged in pairs, each pair having its two members hinged at their proximate inner ends to opposite sides of a vertically-movable. bar E, adjustable for width, their outer ends being hinged to the There are two of these pairs of lock-bars for. each bar E, and they correspond in position to each subsection of the lazy-tong bars. Of course one bar E and the two pairs of lock-bars hinged thereto may be dispensed with whether the construction shown in Fig. 1 be otherwise adhered to or the door or door-section be limited to the space bounded by and including the space A and F.

Each bar E is composed of parallel strips E, which are fastened together near their upper and lower ends by transverse adjustingscrews 0 and separated by interposed blocks or layers 6', respectively, near the upper and lower ends of the bar. By removing these blocks or layers and substituting similar pieces of greater or less thickness with, of course, the necessary alternate loosening and tightening of the screws 6 the bar E will be, increased or decreased in width, of course correspondingly widening or narrowing the door to suit a wider or narrower doorway. Also the upper part of the door may be widened and the lower part left without change, or narrowed,

suit any irregularity of the door-frame,whieh very often is not a perfect rectangle. Sometimes the door-jamb is left with an inner face inclined more or less from the vertical line by inaccuracy of workmanship. In other instances, warping of the wood or a slight settling of the structure may produce the same result, which, however, would be hardly ohservable until the application of the door to the doorway. As these doors are intended largely for use in apartments and other places where the remodeling or cutting of the permanent structure would be objectionable, it becomes highly important to secure a perfect fit by the adjustment of the door itself.

To conveniently operate the bars E and lockbars D, I extend branch cords G G therefrom to cord G, which passes down over a pulley g, as shown in Fig. 1, on the upper part of upright A, the latter cord being provided at its lower end with a hand-knob g, whereby it is pulled at will to raise the bars E and lift the lock-bars D out of their horizontal locking position into an inclined position,(shown in Fig. 2,) which permits the door to be folded together. The two sheets or curtains a at all times effectually hide the cords G G and the inner mechanism of the door,but in said figures one of the said sheets has been mainly broken away to show said cords and mechanism.

In some instances, as shown in Fig. 3, I provide for making the door thinner by arranging the latch-bars D altogether in the space 71 between the two series of lazy-tong bars instead of overlapping the said series. In this construction the middle bar or strip F corresponding to F, before described, is connected at its top and bottom to the proximate parts of the two lazy-tong series, which are continuous from upright A to upright A Consequently it does not extend over them to add to the thickness of the door. This last feature, however, is not essential, since it might be extended from top to bottom of the door without increase of thickness, provided each series of lazy-tong bars were divided into two subseries arranged and attached as in Fig. 1. In this form of my invention the two branch cords G G are dispensed with and the single cord G is connected to both bars, passing from one to the other through bar F preferably overapulley or antifriction-rollerf, journaled therein. This point affords a fulcrum for the upward pull on the bar E, to which the end of the said cord is attached. As the cord passes under apulley f" in the upper end of the other bar E and runs thence to and over the said pulley g, a pull on said cord will raise both of said bars vertically, lifting the lock-bars into inclined position, as shown in dotted lines in Fig. 3, and leaving the door free to contract.

It is very desirable to provide for easily drawing out long door-sections or doors and also to insure immunity from unnecessary rubbing of the floor when they are folded together and turned out of the way. For these purposes I supply a caster or roller M on the lower end of a vertically-movable bar N, proximate to upright A and connected at its upper end to the lower lock-bar D, hinged at P to said upright. When the said lock-bar is lowered into horizontal position, this caster or roller is forced down against the floor and will sustain the weight of the door and lessen the friction of its motion; but when the door is folded together the roller is no longer needed and would be in the way, besides wearing the carpet or floor unnecessarily. Accordingly the upward unlocking movement of said lock-bar lifts the said roller or caster above the floor.

1f the bar N were connected directly to the lock-bar D at this point, it would not have sufficient vertical play to reliably elfect this result. Therefore 1 interposc an inclined connecting-block 0 between them, making this adjustable on the under side of the bar vN by screws n and interposed pieces '11 that the amount of play may be properly regulated. The upper end of bar N is connected (see Fig. t) by hinge 01. to the under side of the said block and will be lifted readily and without strain the predetermined distance. When the barD is forced down into the lirst-mentiomal or locking position, it bears squarely on the upper end of bar N, which is in alinemcnt with the hinge P aforesaid. This also assists in enabling me to lock adoor or section of a door securely without any mortising or other change of the woodwork, which is, perhaps, the most important feature of my invention. The said caster thus forced and held against the floor or sill is the lower of two folding or clamping devices thrust, respectively, upward and downward against the proximate parts of the door-frame or other permanent elements of the house structure. The other locking element or device is a bolt R, having a rubber head 1' arranged to bear upward against the lintel of the door-fran1e. This bolt is mounted on a plate S, which is fastened to the upright A above the pulley before mentioned, or it may be opposite said pulley and on the other side of the door. The said bolt is guided by an arched metal strap T, which is held to said plate and upright by screws t. For the purpose of adjusting its movement and the degree of compression of the rubber head the said bolt is provided with a stem S of less diameter, screw-threiuled at i' s into the similar]y-screw-tapped lower end of the body of the said bolt. The lower end of this stem has a crank-arm a integral therewith, the same being connected eccentrically to an operating-disk V by a wrist-pin or stud V. This disk is journaled on a stud \V, removably attached to the plate S, and is provided with a handle W. A recess X in stem S above the said crank-arm serves to engage the stud as shown in Fig. 5, when the bolt 18 withdrawn downward out of action,

and' such engagement locks the bolt and operating-disk in such'position until they are freed by suitably turning the said disk. By turning the handle in the direction of the arrow. marked on Fig. these parts are thus freed, the head 1 of the bolt is compressed against the lintel above it, and the handle W is turned to andbeyond the point'of alinement with the stud W and the bolt, so as to hold the latter securely in such position until said handle is turned back again for withdrawing the bolt. Rubber isthe best material, as stated, for the head therefor, but felt-or any other substance having the requisitecompressibility and friction may be substituted if of anature not to scratch the lintel while holding the top of the door securely th ereto. Of course equivalent constructions of the bolt permitting longitudinal adjustment and other forms of disk or cam or their equivalents having substantially the eccentric locking action above described may be substituted for those hereinset forth.

When the caster or roller before described is locked down on the floor or sill and the said bolt is locked up against the lintel, the doorsection to which they are attached is securely locked in place, reducing the door-opening by one-half, while the other section of the double door will be left free for the opening. If a narrower door of only one section be used, these parts will answer the purposes of a latch in all ordinary circumstances. There is no need to. mortise or otherwise deface or change the lintel or sill or floor, and no'part of the permanent structure will be marked or in any way made unsightly by any movement of the door. When out of use, the latter will be compressed into small compass and turned aside, if desired, on ordinary door-hinges as, connecting upright A to the door-frame. As the operative parts are concealed between the sheets or curtains a when the rollers are used, or may be arranged and decorated in a pleasing manner when only one roller is used, the door of'either kind becomes ornamental and well suited to apartments of thecostliest structure and furniture.

When it is desired to close the doorway, the" door being then incontracted conditionand turned out ofrthe doorway, as stated in the last preceding paragraph, it is first turned into the said doorway on the hinges connecting it carrying said caster, and as the hinge P con- As the said lock-bars are in alinenects to upright A the bar D, whichis hinged by n to said rod, there is need only of a de vice forced upward against the lintel of the door and held so approximately in line with said rod to lock the saiddoor securely by upward and downward pressure. This locking not only reinforces that of the lock-bars D,-

The movement of bars D into horizontal po- I sition above described will draw up the free end of the cord Gr. .When' the door is to be opened, the bolt R is drawn down, as above described, and the free end of said cord is also drawn down, lifting the caster M off from the floor, as shown by full lines in Fig. 2 and by dotted lines in Fig. 3. This pull draws the outer upright A toward the inner upright A, thereby contracting the door, which is shown in partly-contracted position in Fig. 2. Pressure onupright A or a pull on it toward upright A will assist this operation,-the toggle-levers yielding to permit the same.
