DOOR-LATCH.

Specification of Letters Patentf Application ilefl lSeptember 30- 1907. Serial No. 395.147.

To all whom it may concern: A

Be it known that I, -J OHN HENRY BROWN,

l a citizen oi' they United States, and a resident of Independence, Montgomery county, in the Stateof Kansas, have invented a new and Improved Door-Latch, of whichthefollowing is a specification.'

This invention relates to improvements in i latches, land the especialobject of the irn-y provements which form the subject' of this application is to provide a novel., inexpensive and practical latch and combineddOor-pull formed ofa wire rod bent into a form, which ids adapted particularly for vvuse on screen oors.

The invention consists in the novel cone struction and combination of parts, as is hereinafter described and claimed. In the accompanying drawings my linvention is illustrated in a preferred form, and in the 'following views similar characters -of reference indicate corresponding parts in all the figures. f

Figure 1, is a side elevation and vertical side view of my invention, as in position when the door is closed, and the broken lilies show the position of the relative parts of the latch with the door slightly opened. Fig. 2, is a top plan view, as seen from the inside of the` door, while the door is closed. Fig. 3, shows first, a vertical side lview of a keeper to be fastened to the doOr-jamb, second, a horizon- .tal 'top view of the same, and third, an end view of the same. Fig. 4, is a plan view of' my invention showing the wire frame and the movable hook secured therein -readyy tov be placed upon a door frame. Fig. 5, is an inside view of a push button, designed to slip over and to secure the end of a push rod. Fig. 6, is a-sideview and a plan view of a metal washer designed to be placed under the keeper at either end when the keeper is laced across a molding on the door jamb. ig. 7, is a guide with points desi ed to be driven into the Ewood on the outside of the doorand to act as a guide for the push rod to pass through. Fig. 8, is asideclevation view, and part in section, of the push rod with the push button secured thereto..' Fig. 9, is a vertical end, view of the wire frame. Fig. 10, is an' end view of the .door hook. Fi 11, is a side elevation view of the'dooi` hoo shown in position as when raised.

Asshown` in Fig.f4, the frame -D is integrally formed from a single piece of resilient wire rod, the speciic `construction ofy which Patented Feb. 25, -190s.

is as follows: Upon one end of the material a half-loop n) is bent, then the wire being bent in a plane perpendicular to this half-loop the wire vis bent so as to form an eye for the push rod Ato pass through, as at m, passing up again withanother curve the wire is bent so as to form a screw eye, then in direct line with the opening made in lthe'half-loop and opposite to the half-loop the wire is given one coil leaving an` opening through this coil oi'- the same diameter as that of the half-loop at the other end, then passing on two other screw eyes are formed as before, so as to be opposite Jthe' screw-eye. and theeye for the push bar already formed, and all oi said eyes being in the'sarne plane, then the wire is bent so as to` form the second half-loop in this end of the wire, so that when pulled into place, and the shaft part'of the hook is inserted into the two half-loops, the half-loops ,will come directly against and' opposite to each other in pressure on the shaft part of the hook, both ends of. the wire in forming the two halfl loo s coming on the same side of thecenter O loops.

As shown in Fig. 1, 4, 1.0, and 11 the door latchgC'is integrally formed'from a single piece .of resilient wire rod, the specific construction 'of which is as follows: Upon one end of the material-a curve as tis made, then curvingl inward at right angles to this curve the wire rod'is continued in a straight projection through :the two halfloops of the wire frameand through coil at the other endy of the frame, then being bent inward to a plane parallel to that of the curve t, the wire `is again curved so as to form a hook, then being bent upward and backward directly back over this pastthe point where the turn was made in the wire just as it came out side the vaperture made in the coil the wire is again turned downward 1n the same lane as before, then outwardand upward the aperture formed in the half v 1n anotherplane per endicular to the pla-ne x of the Ihook part, an kso `as to form aprojection to act as a kicker to strike on the curved l part v of the keeper when the door is closed, -and thus to force the end of the hook C into the aperture inthe keeper At, the' part where the wire comes through said coil a piece of metal or brace'F is passed around the "diierent 'parts of the wire so'as to act', as a washer andalso to hold the wirefin position.

f 13 .is .a push-button having an inside plate 8, 'andan'linner plate q in which there'ls an a erture p, having the part ov at one side t ereof, and on the o having a portion g whic the inside, yet not cut through. A is a pushrod having a ring or finger hold at one end.

thereof and the other end being flattened' with a rojectionon one side thereof so that it may e inserted in the push-button through the alperture p o and turned so the .projection r wil come into the depression g, thus holding the button on the end of this rod.

It will be evident that to open the door, ifv on one side of the door the ring' on the push rod is pulled, thus drawing the push button toward the door; and if it is desired to open the door from the other side then the pushbutton B is pushed in toward the door, thus when the push button B is pushed or drawn in toward the door the curve part t of the hook slides on the inner surface of the pushbutton B and acting as a lever throws the ydoor hook fC out'of the keeper E and back until the said hook comes against the door frame, at which position this hook remains because of the tension caused by the halfloops n pulling o' from each other and binding on the rod part of said hook, although should this tension not be sufficient to hold` thehook up in this position and the hook should fall down then the part of this hook u which I have designated as the kicker, would come against the door frame and would not let the end of the hook drop so low but what by means of the sloping part of the end of the hook it would strike the keeper E and will be raised up and will slide so as to drop into position in such a manner that the end of the hook will be secured in they aperture in the keeper E. And should lthe tension. caused by the half loops hold the hook up in position, then when the door is allowed to go shut, the kicker u of the hook C will strike the raised or curved part ofi the kee er E which will hold the kicker u back an( thus throw vdown the hook C into osition inI the aperture in the keeper E. T e keeper E is and molding k by screws G.y The frame piece D, is fastened to the door frame 1 by three screws G, theremaining screw eye m in the f frame D being left for the push rod to pass through. This construction ofr the frame DV allows play enough for the wire to give conosite side from 0,

is indentedfrom stant tension on the hook at held by the half-hooks n Having described my invention, I claim as new and desire to securevby Letters Patent- 1. In a door latch, the combination of a latch -hookhaving at one end a curved lever and at the other end -a portion designed to en age a keeper, also a portion, acting as a kiter, with an integral frame having screw eyes and having a coil at one end with two half-loops at the other end of the frame, a push-button in connection with a push-rod, uponwhich rod is a ring, a keeper ,designed to be placed on the door-jamb. Y

2.. In a door-latch, an integral hook having a curved part at one end, and at the other end an enga ing portion formed by bending the wire ro inward, then a little distance the location out on said wire, said wire being bent up and curved down to 'form a hook, then the wire being turned up'at a slant from said curved portion thence turned back again when a little above the plane of the curvedv portion,

and thence upward to form a kicker, a brace p securing the corners of the hook. 3. Ina door-latch, a wire frame, a movable hook,'a push-button, and a push rod, as described and shown. 4. In a door-latch a push rod having at one end a ring and at the other end a portion designed to engage abutton, a button,V a uide for said rod to .pass through, a wire rame with an eye designed for said push rod to pass through, said wire frame having` apertures for secuin latch hook, and a atch-hook designed to be raised by the contact of said push button, a keeper, and a washer designed tobe placed immediately beneath the screw eyes at either vend ofthe said keeper. designed yto be fastened to the door casing j,
