Specication of Letters Patent.

Application led May 26, 1915. erial No. 30,528.

To all whom z't may concern.'

Be it knownthat I, NORMAN C. Nicol., a citizen of the United States of America, residing in the borough of Brooklyn, county of Kings, city and State of New York, vhave invented certain new and useful Improvements in Supports., of which the following is a specification.

My invention relates to supports for holding in separated position a part which is separable from another, such as the cover of a box or phonograph, or the lid of a trunk or chest, and for many other purposes wherein it is desired that one part which may be pivoted upon the other should be supported in extended position. The invention consists in the provision of means whereby the supporting elements, when the lid or cover is raised, will automatically lock the same in such position, and by a further movement of the lid or cover the lock will be released and prevented from rengaging while the lid is approaching the body.

The invention will be`found particularly useful in connection with the support of a lid or cover wherein the supporting means are not easily accessible, as it only requires that the lid be lifted beyond the supporting position, whereupon the supporting parts will be prevented from rengaging during the closin of the lid.

Some o? the forms in which my invention may be embodied are illustrated in the accompanying drawings, wherein,-

Figure 1 is a section through a box and cover illustrating my invention in side view, with the cover supported in raised position.

Fig. 2 is a side elevation, partly broken, of my invention in use with the cover closed, on an enlarged scale. A

Fig. 7 is a similar view of the parts after the lid is partly closed and the locking parts belng prevented from engaging have passed beyond the engaging point.

Fig. 8 is a cross-section .on an enlar ed scale on the line 8-8, Fig. 1, with the ox closed.

Fig. 9 is a side view of a modified form vof my invention.

l thereto at C, but the invention is not necessarily limited in application to a box nor to a structure having separable parts which are pivoted together. According to my invention the supports for the box comprise two elements, one of which is movable relatively to the other to cause them to pass to locking position. Such relative motion is capable of accomplishment by making either one part or the other part move. The moving part may be actuated by gravity or by equivalent means. If the prop D is the movable part, the pin. F will be preferably fixed, but this arrangement may be reversed without departing from the principle of my invention which consists in the provision of means whereby upon a further separation of the parts D, F, the lock between these parts may be released and prevented from rengaging upon the closing movement. I have illustrated the prop D as pivoted to the cover at d, and this enables me to employ a straight prop. If the prop were curved and fixed in position the relative movements of the part would not be obtained by the gravital movement of the prop as in the form illustrated, but for such arrangement a movable pin, spring actuated, could be employed.

According to my invention the prop D is ing movement-.of the prop, and below this 'without entering therein.

pin will drop into the said recess and hold` the parts in supported position.

The means provided by my invention for enabling the closing movement of the. parts to be accomplished without rengaging the.

locking pin and recess, include a guard illustrated as a plate which 1s slidably mounted upon the prop D and 1s desired to have frictional contact therewith so as to in-l vterpose a slight frictional resistance to movement thereon` and this is obtained by providing the said plate with spring-lingers -g, g1, g2, g3, which embrace longitudinal edges of the prop vand permit the guard'to move relativelythereto. i

The guard plate'G is centrally apertured at H and the locking pin F passes through this aperture. The aperture is large enough to permit of play of the guard plate relative to the pin, and the inner walls of the guard are formed to facilitate the entrance of the pin into the locking recess in the prop, and further, when=..the prop is lifted out of position to obstruct the 'entrance to the locking recess so that in the closing movement of the prop the pin will pass the said locking recess In order to accomplish these objects the central aperture H of the guard is provided with an inwardly projecting boss h,.the upper wall'of which at h1 is inclined in a direction lleauling to the entrance of the locking recess E. The top of the guard is formed with a slot h2 which is engaged by the locking pin during the closand at the side thereof opposite the boss h, the wallh3 of the plate is at a lower level than the end of the slot k2, providing for the movement of the" plate so as to raise theboss h1 out of the way when the'pin enters the locking recess E. The portion of the perforation H below the boss h and the wall 71.3 is cut away so as to offer no obstruction to the perfomance of the functions stated. The end wall h4 is located relative to an inclined wall h5 of the slot h2, so that upon a further lifting movement of the yprop the pin F will engage against this end wall la* and move the said inclined wall h5 in position to close the entrance to the locking recess, as shown Fig. 7.

I' have illustrated the rop D as formed with a longitudinal slot il? which receives the pin F and permits the free movement of the slot on the pin, and when the prop is provided with such slot some of the spring-finmoroso edge of the slot D1, as illustrated in Fig. 1,

and that the said prop will have a tendency to receive the pin in the locking recess E when the entrance thereto comes opposite the pin. rllhe passage of the pin through the aperture H in the plate Gr maintains the plate in position relative to the pin, but the size of the aperture H permits of a certain play of the plate relative to the pin, and the grip of the spring-fingers upon the plate on the prop causes the plateto remain in position on the prop until moved by the pin, and accordingly will maintain the said plate in the position to which it isadjusted by the pin until again moved.

esv

The prop D is illustrated as formed with a delecting edge l below the locking recess E, and this is inclined away from the said locking recess so that as the prop is lowered and the pin relatively raised, the said inclined wall I will have a tendency to cause the pin to pass away from the mouth of the recess. In the particular instance shown, the inclined wall is formed as the upper wall of a recess i.

The operationof this form of my invention is as follows: In the closed position,

Fig. 2, the pin F is illustrated as engaging the end of theslot k2, which is the position assumed by the parts in closing. When the cover is lifted the plate will be lifted with the prop until the pinis brought into c ontact with the inclined wall k1, whereupon the pin will move the plate on the slide until the entrance to the slot E is suiliciently un'- prop to fall and admit the pin into the said inclination of the wall k1. The parts will thereupon be in the position of Fig. 4:, in which position further pulling upward on the prop D will cause the prop to wedge or bind 'the .pin F between the end of the proj ection L and the boss I1 and prevent further lifting of the prop.' The cover `being then released, the prop will drop so that the pin F will passto the end of the locking recess E. This will cause the wall k3 of the plate to hit against the pim/movingv the guard upward so that the plate is moved to the position of Fig.' 5, wherein the boss h is raised.

desired. When it is the cover is slmply given an additional'lift-- ving movement causing the raising of the prop sothat the pin F is removed from en- Y gagement with the' locking recess and travels .covered by the projection h to enable theV below the boss I1 formed above'the deiecting edge I. Thereupon the guard will be lifted with the prop until its lower wall h4 is engaged by the pin on the prop for a suitable distance, as for instance, until the pin strikes the end of the recess i which provides a convenient stop for thispurpose. The wall 11.5, which may be inclined for this purpose, thereupon covers the entrance to the locking recess E and obstructs the further entrance of the pin therein. The prop being then lowered, it will travel on the pin until the pin strikes against the deiiecting edge I,

' which will give it a tendency to move away from the entrance to the locking recess E. The guard will have been moved upward by the pin until the pin strikes agamst the said edge I, whereupon the wall h5 being in substantial alinement with the said edge I, the pin F will pass into the end of the slot h2, in which position it will remain while the locking recess E is passed and until the lid is closed to the position illustrated in Fig. 2.

In Fig. 11 I have illustrated a modification applicable to all forms of my invention, which consists in providing the prop D with a boss J, the upper wall of which is located a suitable distance from the wall of the prop at e above the locking recess E to permit of the free passage therebetween of the pin F, and this upper wall is inclined for the purpose of guiding the pin toward the locking recess E.

In the main form of my invention the prop D is illustrated as made of a plate, for which purpose sheet metal is preferred, which is slotted. It is not necessary, however, that the invention should be embodied in a plate, as it may well be formed of wire, as illustrated in Fig. 9, wherein I have illustrated the employment of a single piece of wire K, one end of which is bent into an eye and passed around the other part of the wire at forming an eye by which the parts are held in proper relative position, and between which the slot D1l is formed. The construction corresponds to that illustrated in my main form, with the exception of the spring-fingers which are somewhat differently positioned. Y

in the modified form of my invention illustrated in Figs. 12, 13 and 14, the guard, in place of being slidably mounted on the prop D, is directly mounted thereon and is 'Si moved in position by relative movement between the pin and prop, as in the previous forms of my invention. The guard, which I shall here letter G1, serves the functions of the sliding guard G in that it provides a stop by which the prop is held when it arrives at its position opposite the locking recess E, and this stop is removed by the passage of the prop over the pin, and then upon a further separation of the pro-p and pin a portion 'of the guard is moved across the entrance to the slot so that the slot is blocked and the rentrance of the pin therein obstructed and prevented. I have here illustrated the guard as formed of two parts, to Wit, :t stop member X which is pivoted to the prop at w, and a deflecting member Y which is similarly pivoted to the prop at y. The defiecting member Y is provided with a tail-piece y1 and with ashoulder y2.

When the prop is lifted and the slot D1 is moved relative to the pin F, the stop member X drops freely on its pivot under the infiuence of gravity untilits toe abuts against the shoulder y2 on the deiiecting member Y, and thereupon, by engaging against the tailpiece y1 it holds the forward end ya which drops by gravity across the slot D1 in position to engage against the pin F and prevent the further movement of 4the prop. Thereupon the box cover may be dropped and the action of gravity will cause the locking recess E to pass over the pin will throw the stop X' away from the tailpiece y1, permitting the delecting member Y to passto the position shown in Fig. 13. Thereupon a further'opening movement of the lid will cause the prop to be lifted until the point ya of the deflecting member Y passes the said pin. At this time a iixed pin y* prevents the point ya from passing entirely away from the slot. The prop being then lowered, the pin F engages against the inclined face g5 of the deecting member Y and lifts the same to the position shown in Fig. 14, Where it 'guards the entrance to the locking recess E and enables the pin and prop to pass without rengaging.

In this form of my invention, while I have illustrated the guard as working hy gravity, I do not preclude myself from the employment of other equivalent means for obtainingor assisting this action.

In my invention, when the cover has been closed sufliciently so that the pin has passed the entrance to the lockingrecess, the guard is restored to initial position by the pin engaging against the slot 7a2, which, in the construction illustrated, is shown as a slot which is closed at one end but which is not necessarily so. Thereafter the cover may be moved to any desired extent without changing the guard from such initial position relative to the locking recess; the cover is moved. when it 1s opened again, the guard will always be in proper operating position. This presents the important advantage that the prop and pin may be placed in any desired position on the box, as the extent of movement does not affect the operation of the locking parts.

I have illustrated in the accompanying drawings the most desirable form of constructing my invention .now known to me,
