Original No. 1,341,583, dated May 25, 19207 Serial No. 348,357, le'd December 30, 1919. Application for reissue led July 10, 1920.

To all whom t may concern Be it known that I, THOMAS V. Pinon, a citizen of the United States of America, re`1 siding at Ashland, in the county of Ash= land, State of Ohio, have invented a new and useful Door-Latch` and Controlling Devices for Combined Hinge and Slide Doors, of which the following is a specification.

My invention relates to locking and controlling mechanism for doors, and is particularly applicable to doors of the combined sliding-and swinging type, such as used on garages and stables.

The chief object of my invention is to provide simple means whereby the doors may be effectively locked or latched` in the closed position, said means being easily reversible, and said means being so construct-` ed that it may be used to facilitate the opening of the doors. Other advantages not specifically mentioned will be apparent to a mechanic familiar with this art from a reading of the following description and an eX- amination of the accompanying drawings inx which Figure l is a front view of a pair of hinged doors arranged to both swing and slide from the closed position shown, to the open position illustrated in dotted linesv in Fig. 2.

Fig. 2 is a sectional view of the parts shown in Fig. 1 looking down.

Fig. 3 vis a view similar to Fig. 2, but showing the doors arranged'to swing inwardly instead of outwardly, asV shown in Figs. 1 and 2.

Fig. el is a relatively enlarged plan view of my invention with portion of the doors shown in section.

Fig. 5 is a front elevation of the parts shown in Fig. 4.

Fig. 6 is an edge view of a door equipped with my invention.

Fig. 7 is a front elevation of certain cle tails.

Figs. S, 9 and 10 are views of detached details.

I will first describe that type of a door to which my improved locking means is particularly adaptable. In Figs. 1 and 2, I have shown a two section door the two sections being indicated at 1-2 These sections are hinged together at 3, while the section is hinged to the door casing at 4. 5 is a swivel Serial No. 395,386.

, hanger ofany suitable constructionsecured to the upper edge of the door to `run along a track 6. The hanger 5 serves to, support the free edge of the two doorsections 1 2. The hinges B-tare arranged on opposite sides of the door. In the form shown in Figs. 1 and 2, ,the door sections are intended to buckle outwardly so that they willfold back into the position yindicated in dotted lines. In Fig. 3 the aforesaid hinges are reversely arranged so that the door will buckle inwardly and fold back into the position shown in dotted lines in said gure. When the doors buckle outwardly, the latch portion of my invention will be located on the outside of the door, and when the doors are arranged to buckle inwardly, the latch is arranged on the inside of the door sections. The latch is constructedA to automatically operate when the doors lare closed so as to hold the two sections inline. Frequently such doors are equipped with an overhead spring latch bolt which snaps into a keeper glatte in the upper part ofthe door casing.

uch a bolt is indicated at 7 in Fig. 6. M locking mechanism is so arranged that the act of unlatching the door will automatically operate to retract the aforesaid overhead latch bolt.

My automatic latch mechanism comprises the following parts 8 is the base of a latch carrying frame designed to be screwed or bolted to either one of the door sections 'adjacentto the break between said sections, and on the opposite' side from the hinge thereat. In Fig. 4 I have shown said base as secured to the section 1. Projecting4 outwardly from the base is a center bearing Q 10-10 are horizontally located spaced jawsfat one side of said center bearing forming a socket for the tongue 21 later described; The center bearing is cut away directly behind the jaws 10-10 to provideroom for the hub 11 of a swinging latch. 12 is a shaft ,or spindle which passes through the door section 1, and through the center bearing 9, and through the hub 11 of the latch. 14 is a set screw by which the hub may be'locked on the shaft or spindle 12. 15 is a handle at the outer end of the latch by which said latch may be lifted. 16 is the nose of the latch, the side of said nose nearest the hub 11 furnishes an abrupt wall for performing the latch function, while the opposite side of said nose is beveled as indicated at 16a. 17 is a stop on the hub 11 of the latch. 18 is an arm projecting upwardly and rearwardly from the body of the latch near the hub, the function of which arm will be later explained. The nose of the latch is arranged to drop down by gravity in front of the aws 10-10 as b est seen in Fig. 5. That part of the latch between the handle 15 and the hub 11 may be extended laterally to provide in effect wings, each of which is preferably provided with two passages or holes 192l at its opposite side edges. The upper and lower sides of the frame upon which the latch is mounted both correspond, so that the latch may be associated with the frame on either side, said latch being detached therefrom, simply by loosening up on the set screw 14 and pulling out the spindle 12. To attach the latch, the hub of the same is put into place as shown in Fig. 4 on the desired side of the frame. The spindle is then re-inserted through the center bearing 9 and the hub 11, and the set screw again set up. The other section of the latch mechanism which is attached to the other section 2 of the door comprises a suitable base 20, (see Fig. 9) which is adapted to be screwed or bolted to the door section 2 in front of the latch proper. Projecting outwardly from the base 20 is a frame which includes a forwardly projecting horizontally positioned male member or tongue 21, arranged to project into the space betweenV the jaws 10-10 when the door sections are straightened out. 22 is a recess or hole in the tongue into which the nose 16 of the latch drops so as to lock together both sections of the latch mechanism and hold the door sections in the straightened out position. Projecting laterally from the tongue is a. wing which is provided with a hole or passage 23, which is arranged to line up with the out-side hole or passage 19 of the latch, so that the hasp of a padlock may be passed throughv these holes 19-23 to positively lock the latch in its holding position. 24 is a loop extending outwardly from the base 20 and forwardly to the tongue 21 to form a hand-hold, said loop also bracing and strengthening the parts. On the 'opposite side of the door from the latch proper is located a handle or lever 25, which is properly secured to the end of the spindle 12, so that by swinging said lever the latch may be operated from that side. This lever 25 has one or two offsets 25a each forming in effect a bell crank lever which may be used for operating an overhead bolt in the manner hereafter described. 26 is a keeper plate mounted on the door adjacent-to the free end of the lever 25, the said keeper plat-e having an offset bar 27. The end of the lever 25 may have a hole therein, so that the hasp of a padlock may be passed through the same and under the keeper bar 27 to lock the latch on that side of the door. overhead spring latch bolt 7 is mounted in a suitable case 7a, which may be secured to the door section upon which the aforesaid latch is located. The tail of this spring latch bolt 7 may be connected by a chain or wire 28 with the arm 18 of the latch (or with one of the bell cranks 25L of the lever 25) so that whenthe latch proper is lifted, it will simultaneously and automatically retract the spring latch bolt 7 thereby at once unlocking the two door sections 1-2 so that they may be buckled, and unlocking the door sections from the overhead casing to permit said buckling of the door sections. In the drawings, Fig. 6, I have shown the spring latch bolt 7 as connected by wire to the bell crank arm of the lever 25, because in that particular figure, the door is intended to buckle outwardly, and obviously the latch bolt7 should always be on the indoor side. If the door were designed to buckle inwardly, then the latch mechanism would be located on the inside of the door underneath the spring latch bolt 7, and the wire 28, in that event, would be connected with the arm 18 of the latch. If the door had a lower bolt corresponding to the bolt 7, its connecting wire would be connected to the latch through the hole 19a. If it were desired to have a spring latch bolt in the lower edge of the door to take into a keeper on the door sill, it is obvious that such an arrangement could be provided, in which event'another latch bolt 7 like that shown inv Fig. 6 would be provided for the lower edge of the door.

No separate illustration is required because this mere duplication is Verfectly obvious.

lVhen the doors stan ajar, as shown in dotted lines of Fig. 2, they may be easily The I closed by grasping the hand-hold 24 and pulling the same to the right as viewed in said figure. As the doors straighten out, the edge of the tongue 21 engages the bev eled edge 162l of the latch, so as to automatically lift the same. It then enters the socket space between the jaws 10-10, so that the doors will be held against independent vertical movement and so that when the doors are fully straightened out, the nose 16 of the latch will drop down into the hole 22 so as to securely hold the door secl tions in the straightened out or in closed position shown in solid lines Fig. 2. The stop 17 serves to hold the latch in the proper position when the doors are buckled, sothat when said doors are closing, the tongue 21 will properly'engage the bevel 16a to lift the latch. The case 7'c1 for the latch bolt 7 is of cylindrical form, and is provided at diametrically opposite edges with two corresponding flanges, one of which is shown at 7b. The flanges receive the bolts or screws by which the case is secured to the door,

the whole of said case stood above the surface or" the door, it would tend to limit the deoree to which the doors could be brought c c together when folded back.

It will be understood that I have shown and described my invention only in its preferred form, and that I fully appreciate that various modilications in the design and arrangement of parts may be had without departing from the spirit and scope of my invention.
