SLIDING-DOOR FASTENER.

SPECIFICATION formingpart of Letters Patent No. 686,732, dated November 19, 1901.

Application filed February 21, 1901. Serial No. 4&239- odem T0 C/ZZ 1072 0122, it may concern.-

Be it known that I, JOHN T. HICKS, a citizen of the United States of America, and a resident-of the city of Boston, county of Suffolk,

5 and State of Massachusetts, have invented certain new and useful Improvementsin Fasteners for Sliding Doors, of which the following is a specification.

This invention relates toa fastener for slid- Io ing doors of the kind used on show or exhibition cases and similar constructions, the object being to provide a simple, cheap, and efficient locking device which cannot easily get out of order and which will be durable,as

well as of unusual strength; and the invention therefore consists, essentially, in the construction, arrangement, and combinaton of parts and in numerous details and peculiarities thereof, substantially as will be hereinafter more fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure l is a perspective view of a show-case provided'with my improved fastener. Fig. 2 is a cross -section of the same. Fig. 3 is a detail perspective view of the looking-bar. Fig. 4is adetail view showing a modified form of the device that engages the locking-bar. Fig. 5 is a sectional view of this modification.

0 Similar numerals of reference designate corresponding parts throughout all the different figures of the drawings.

1 denotes a show-case as shown in the drawings. It is of a common form, having 5 a wooden frame and glass sides and top;

but this form is given simply by way of example, and I reserve the liberty of applying my fastener to any style of show-case to which it may be found applicable. The show- 40 case 1 has at the rear side three sliding

doors

2, 3, and 4, which move in suitable ways or grooves, the

doors

2 and 4 being set slightly to the rear of the middle door 3, so that when said

doors

2 and 4 are moved for the purpose of permitting access to the interior of the show-case they will slide over the face of the middle door 3, and when said middle door 3 is moved it will slide behind one or the other of the

doors

2 or 4, it being noted, of course,

that each of the three doors is slidable and of preventing the removal of the bar.

permits access to the portion of the showcase immediately in front of it. The common practice in securing these doors against unauthorized entry into the show-case is to provide each one of them with some sort of a 5 locking device that will cause an engagement between the frame of the show-case and the door; but so far as I am aware such devices are intricate in construction, as well as expensive, and have proven failures in use. I aim by the employment of a device of extreme simplicity to effectively fasten all three doors with a single fastening device.

The middle door, as 3, is provided at a point near the bottom edge thereof with a 0 projecting horizontal bolt or pin 5, which may be fastened to the door 3 in any desired manner. It may be integral with a small plate 6, which is secured to door 3 by means of screws or pins 7. 8 designates a lockingbar of metal, wood, or other strong material and of a suitable length to fit neatly between the adjacent edges of the

doors

2 and 4 when the latter are in the closed position. (Shown in Fig. 1.) Bar 8 has a central orifice or slot 9 of proper size and shape to enable the bolt 5 to pass through it when the bar is placed in its operative position. (Shown in Fig. 1.) The bolt 5 is provided near its outer end with an eye or hole 10, intended to be engaged by a padlock 11 after the bar 8 has been placed in position for the purpose As before suggested, the bolt 5 is situated near the loweredge of the door 3, to which it is attached, in order that when the locking-bar is in position its bottom edge will rest quite or nearly in contact with the adjoining edge of the frameof the show-case, so that said locking-bar will be kept in its horizontal position 0 and cannot be shifted to an extent that would destroy its function of serving as a barrier between the

doors

2 and 4. After bar 8 has been placed upon the bolt 5 the padlock 11 may be fixed in place. The removal of the 5 padlock of course permits bar 8 to be removed and the show-case unlocked. When bar 8 is in the position shown in Fig. 1, it will be observed that door 2 cannot be moved to the right, door 4. cannot be moved to the left,

and door 3 is also stationary and immovable because of the relations that these parts bear to the locking-bar and the pin 5.

A modification of the bolt device carried by the middle door is shown in Fig. 4, wherein the middle door 3 is provided near its lower edge with a square recess 12, in which is sunk one leaf 13 of a two-leaf hinge, said leaf 13 being fastened in place by means of screws 14. The other leaf 15 of this hinge device is adapted to open downward away from the stationary leaf 13; but it will be noted that the recess 12 is deep enough to contain both leaves when leaf 15 is closed against leaf 13, thus keeping leaf 15 when desired flush with or below the surface of door 3, so that there may be no projecting points on the face of said door. Hinge-leaf 15 is provided near its end with a slot or orifice 16. The lockingbar 8 has a slot 17 therein of somewhat different form from the slot 9 shown in Figs. 1 and 3, but having a similar function, in that it is designed to receive the movable leaf 15. WVith this modification, therefore, it will be understood that when the bar 8 is to be placed in position between

doors

2 and 4 the leaf 15 will be removed from recess 12 and placed in the horizontal position shown in Fig. 1, after which the locking-bar may be placed over the leaf 15 and then the padlock 11 caused to engage the eye 16. In Fig. 5 the shape of the recess 12 is shown and the position of the hinge devices when both leaves are contained in said recess, and the dotted lines indicate the position of leaf 15 when removed from the slot and placed in its operative position.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-- 1. In a fastener for sliding doors, the combination with the case, of a series of sliding doors, a fixed device on the middle door of" the series, and a locking-bar engaging said device, together with means for keeping the locking-bar in place.

2. In a fastener for sliding doors, thepombination with the case, of a series of sliding doors, the middle one of which is provided with a fixed device consisting of a foldable hinge, one leaf of which is perforated, a locking-bar adapted to engage the perforated leaf, and a padlock for keeping the bar in place.
