UNITED STATES PATENT OFFICE.

JOHN T. HICKS, OF BOSTON, MASSACHUSETTS.

SLIDING-DOOR FASTENER.

SPECIFICATION forming part of Letters Patent Nou 705,529, dated July 22, 1902. Application filed November 13, 1901. Serial No- 82,092. (No model.)

To atZZ whom 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, and State of Massachusetts,haveinvented certain new and useful Improvements in Sliding- Door Fasteners, of which the following is a specification.

This invention relates to means for fastening or securing a sliding door, being principally designed to fasten sliding doors of showcases. An example of door to which it may be applied is the three-slide arrangement commonly found at the rear of a glass show-case, where the doors slide over each other in such a manner as to permit access to any desired point within the case.

The invention consists in certain improvements upon the sliding-door fastener shown and described in my copending application for Letters Patent, filed February 21, 1901, Serial No. 48,239, on which I have obtained Letters Patent No. 686,732, dated November 19, 1901, and it may be said to comprise certain details and peculiarities in construction, combination, and arrangement, substantially as will be hereinafter described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a perspective View of a show-case whose doors are provided with my present novel and useful fastener. Fig. 2 is an enlarged perspective view of the several parts separated from each other and shown in detail. Fig. 3 is a sectional detailed plan view of the several parts arranged in operative relation toeach other. Fig. 4 is a detailed View of the tubular bushing in the door.

Similar numerals of reference denote like parts in the difierent figures.

In the example of sliding door illustrated and described herein, 1 denotes a show-case having the

rear doors

2, 3, and 4, 3 being the middle one and being so situated with reference to the other two that a locking-bar 5 can be secured to the face thereof with its ends between the vertical opposing edges of doors 2 and 4, and when so situated the parts will all be securely fastened together and the showcase effectually protected against any unauthorized entry which might occur in consequence of the opening of any one of the doors.

One of these doors, as 3, is provided near its bottom edge with a perforation or transverse passage, which is lined by a tubular bushing 8, having therein the passage 7 and also having on the outer face of the door a circular flange 9, that is depressed or set into a recess in the face ofthe door, while the innerend of the bushing or sleeve 8 is internally screwthreaded and engaged by a second smaller sleeve 10, having a circular flange 11, similar to the flange 9 and operating against the inner face of the door 3. The passage 7has an offset groove or not-ch 7, and the

sleeves

8 and 10, as well as their flanges, are slotted or cut out, so as to leave the groove '7 open to permit the passage through it of the lugs on the locking-pin.

12 denotes a locking-pin, a portion of which is round and provided with a lug 13 near the outer end of the round part and a lug 14 near the opposite end of this round part. Adjacent to the round part of the pin is a square portion 15, and at the other end of the pin is a slot 16 of the proper size to allow thecurved locking-shank of a padlock to pass through it; The locking bar 5 is provided with a square passage 17 of proper size to receive the square portion 15 of the locking-pin. The padlock 6 may be of any convenient and preferred design and is intended to engage the slot 16 after all the parts have been placed in fastening position.

When the door is to be locked, the lockingpin will be passed through the passage 7 ,which can easily be done because the offset groove 7 a will allow the lug 13 to slide through from one side of door 3 to the other side, and after the pin has thus been passed through the opening 7 it can by being slightly turned on its axis, so that the lug 13 will clear the groove 7 be brought into a position where it cannot be withdrawn from the passage 7 or pushed in one direction or the other, for the lug 13 will efiectually prevent it from being withdrawn in one direction, while the lug let, be ing on the outer face of the door, will/efiec tually prevent the pin from being thrust into the-interior of the show-case. After the pin has been thus placed in a non-withdrawable position the locking-bar 5 can be connected therewith by causing the slot 17 to receive the square portion 15.

Bar 5 will now be locked between the opposing edges of the doors 2 and 4. After the padlock is locked to the pin 12 by being caused to engage slot 16 the bar 5 cannot be removed from the locking-pin, and all the parts will be tightly and efiectually connected together and a firm fastener for the sliding door provided.

Obviously when the door has been unfastened all the fastener parts may be removed and there will be no unsightly projections left on the door, as nothing will be visible thereon of the fastening device except the sleeve or bushing, and it will present no objectionable appearance and no projecting parts that might be in the way of an easy shifting of the door in any direction the user might please. I preferably provide the bar 15 with an eye 18 in order that after the door has been unlocked the padlock may be caused to engage said eye,or by means of said eye the padlock, bar 5, and pin 12 may be all fastened together until the time comes for the door to be again locked.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a sliding-door fastener, the combination with a series of doors, of a removable fastening-pin for the middle one of the series, said pin having means for securing it to said door, a bar for engaging said pin and adapted to have its ends engage the opposing edges of the other doors, together with means for securing the bar upon the pin.

2. In a sliding-door fastener, the combination with a series of doors, the middle one of which is provided with a transverse passage, of a sleeve or bushing therein, a pin adapted to be inserted into the said passage, said pin having means for securing it to the door, a locking-bar having a slot or opening designed to engage an angular portion of the said pin and means for fastening the pin and bar together.

3. In a sliding-door fastener, the combination with a series of doors, the middle one of which is provided with a transverse passage, of a sleeve or bushing in said passage, a pin having lugs thereon designed to engage the opposite faces of the door when the pin is in the said passage, said pin having also an angular portion and a slotted end, a locking-bar having an opening adapted to engage the angular portionof the pin, and a padlock for engaging the slotted end of the pin after the bar has been located on the pin.

4. In a sliding-door fastener, the combina- Witnesses:
