FASTENE'R FOR HOLDING OPEN SASHES, TRUNK S, 80C.-

SPECIFICATION forming part of LettersPatent No. 240,263, dated April 19, 1881.

Application filed October 8, 1880.

To all whom it may concern:

Be it known that I, ALPHONSE MoNTANT, of the city, county, and State of New York, have made an invention of certain new and useful Improvements in Catches, Stops, or Stays for Holding Open Sashes, Trunk-Govers, and Similar Articles, of which the following is a specification.

My present improvements have reference to the class of catches described in my Patent No. 230,326, which, when the article to which one of them is secured is raised, catch automatically upon a rest or abutment and secure the article in its raised position, but which, when the said secured article is slightly raised, so as to lift the point of the catch from its rest, free themselves automatically from the rest and permit the article to be lowered. The form of catch described in my said previous patent included a spring by means of which the engagement of the catch with its rest was effected. In an application for a subsequent patent I described a form of latch in which the movement of the catch in thedirection for engagement with its rest was effected bya spring or weight, and the movement in the direction for disengagement was effected by a spring.

As springs are liable to be broken, the object of the present invention is to enable the catch or stop to be moved in both directions by a weight, which maybe'either a part of the catch itself, or may be a piece of material secured to it or connected with it, and which is automatically transferred or shifted from one side to the other of the pivot (or its substitute) on which the catch moves by the operation of moving the article to which the catch is applied; or, if the catch is arranged to slide, the said shifting weight may be connected with the sliding catch so as to operate it automatically alternately in both directions without requiring the application of the hand to the weight to shift it. One of my improvements has reference, further, to the locking of the article when closed.

The invention may be embodied in various forms, depending upon the nature of the arti-' cle to which the catch is to be applied or the views of different constructors.

In order that the invention may be fully understood, I have represented in the accompanying drawings, and will proceed to describe,

(Models) two modes in which I have embodied the invention.

Figures 1, 2, 3, and 4. represent the improvements embodied in a stop for window-sashes. Figs. 5, 6, 7, and 8 represent parts of the invention embodied in a stop for chest-covers or trunks.

The sash-stop represented in Figs. 1, 2, 3, and 4 is a piece of metal, A, about one-fourth of an inch thick and one and three-fourths inch long, slotted longitudinally to admit a pivot, b, on which it can turn and by which it is connected with the sash. The slot is so located with reference to the weight of the article that when either end of the slot is in contact with the pivot the weight of the end of the stop corresponding with opposite end of the slot (or that which is farther from the pivot) preponderates over the weight of the end of the stop adjacent to the pivot. Thus, when the stop A hangs with one end, 0, of the slot in contact with the pivot, as in Fig. 1, with what may be termed for distinction the point 01 of the stop uppermost, the weight of the part 9 of the stop, which for distinction may be termed its butt, and which is at the time farthest from the pivot b, .preponderates over the weight of the point d of the stop; but when the stop hangs on the pivot, as in Fig. 3, where the end or butt 9 of the slot is in contact with the pivot, the weight of the point (1 of the stop (which is then farthest from the pivot) preponderates over the weight of the butt g. The stop thus constructed, andhaving the capacity to turn in either direction by itspreponderating weight Without requiring the action of a spring, I term a springless automatic shifting weight-stop. The butt 9 of the stop is constructed with a shoulder, 8, adapted to engage with the corner of the rest or abutment (J, which holds the stop when the sash is raised. While the sash is being'raised the stop occupies the position shown in Fig. 2, with its butt or shouldered end 9 hanging down and the point end e of the slot in contact with the pivot 12. As thestop is raised it passes by the rest 0 and occupies the position above it represented in dotted lines in Fig. 2,

. sothat if then the sash be lowered the butt or shouldered end 9 of the stop strikes the rest. The rest then stops the stop from descending, but the slot 0 o of the stop permits the pivot b and sash to descend farther, thus shifting the pivot progressively toward the butt g of the stop until the stop attains the position shown in full lines in Fig. 3, when the pivot b is at the butt-end c of the slot 6 0, and the further descent of the sash is stopped. This descending movement, however, by carrying the pivot or pinto the butt-end of the slot of the stop, shifts the preponderatin g weight at one side of the pivot from the butt g of the stop to its point d, and the preponderating weight tends to turn the stop in the direction of the arrow f. Hence, if the sash be slightly raised so as to lift the shoulder 8 above the rest 0, the stop at once reverses its position on the pivot, as shown in dotted lines in Fig. 4, leaving the sash free to be lowered. The stop Ais now reversed as respects its position when rising, (which, as before stated, is shown in full lines in Fig. 2;) hence it must be restored to that position before the sash is raised a second time. To effect this restoration the rest 0 is of box form, as shown in dotted lines in Fig. 4 and as the sash is lowered the rounded projection r of the stop is brought in contact with the upper corner of the rest 0, which causes the stop to turn on its pivot and its point (1 to swing into the box-cavity of the rest and to engage upon the under side, at, thereof, as shown in full in Fig. 4. Then the continued descent of the sash carries the pivot toward what is then the lowest end, 6, of the slot of the stop, thus shifting the preponderating weight toward its opposite end, 0, as shown in full lines in Fig. 4, and as soon as the weight of the butt 9 preponderates over the weight of the point 01 at the opposite side of the pivot the stop turns in the direction of the arrow h in Fig. 4 and assumes the position shown in full lines in Fig. 2.

In place of making the rest or abutment G of box form, with its lower side, n, acting as a restorer for the stop, a restorer made separately from the abutment may be used.

It will be perceived from the foregoing description that the action of the stop in both directions is automatic, it being effected without touching the stop by the hand, and also that the action in alternately-reverse directions is effected by the shifting of the preponderating weight from one side to the other of the pivot on which the stopturns, and without the use of a spring.

In order that the same stop may be used to lock the sash when it is closed, thereby preventing its opening from the exterior, the stop is fitted with a hook, i, which engages with a holdfast, j, when the sash is in its lowest position and locks the sash or holds it from rising nal movement of the stop on its pivot while the sash is raised from the position shown in full lines in Fig. 3, one end of the slot is notched laterally, as at a, so that it hangs securely upon the pivot while the stop is turning thereon.

In order, also, to prevent the accidental dis placement of the stop while rising when it is set as far from the edge of the sash-casing as it is shown to be in the drawings, a guardstrip, 15, is applied to the casing to act in combination with the stop while it is being raised.

The hook thus described may be applied to the sash-stop described in my previous application, thereby embodying one part of my present invention.

When the invention is applied to a trunk stop or stay the automatic shifting weight-stop A is constructed, by preference, as shown in Figs. 5 to 8, inclusive, with a heavy protuberance, 9, over the slot 0 0. One end, 0, of the slot also is notched laterally, as shown at Fig. 6, so that this end tends to hang securely on the pivot unless the stop is displaced by contact with an obstruction. When the lid is closed the weight of what may be termed the point 01 of the slot preponderates over the residue at the opposite side of the pivot, as shown in Fig. 1. If then the lid be raised, the point hangs down and engages with any one of the notches of the rest or abutment G. If,

when the stop is so engaged, the lid be released by the hand, the slight downward move ment of the lid permitted by the slot 6 0 carries the pivot to the opposite end, 6, of the slot, thus shifting the preponderating weight to the other side of the pivot 12. Hence, as soon as the lid is slightly raised the stop turns on its pivot to the position shown at Fig. 3, leaving the lid free to be shut. In order to restore the stop to the position shown in Fig. 1, a stud, n, is fitted to the trunk within the range of motion of the part w of the stop. Hence as the lid is lowered the contact of the stop with the stud n shifts the position of the stop on its pivot and restores the pivot to the notched end of the slot, as in Fig. 5.- The stud 11 thus constitutes the restorer for the stop, and corresponds in this respect with the lower side, a, of the box-rest of the stop first above described. The end of the trunk-stop is fitted with a hook, to; but in this case the hook does not operate in combination with a holdfast to hold the lid closed, but is used to hold the trunklid when thrown open beyond the perpendicular, as in Fig. 8, by engaging with the pin n, which is in the proper position to be engaged by the said hook.

I claim as my invention 1. The combination, substantially as before set forth, of the springless automatic shifting weight-stop, constructed as before set forth, the rest with which it engages when raised, and the restorer by which the position of the .said stop upon its pivot is changed previous to a second engagement with said rest.

2. The combination, substantially as before set forth, of the said springless automatic shifting Weight-stop, the rest therefor, the re storer, the hook at the end of the said stop, and holdfast with which said hook engages when in its lowest position.

3. The combination, substantially as before set forth, of the said springless automatic shifting weight-stop, the rest therefor, the restorer, and the guard-strip which prevents accidental displacement of said stop. [0
