Application filed March 24, 1915. Serial No. 16,817.

To all whom it may concern:

Be it known that I, GEORGE HENRY BOWEN, Jr., a citizen of the Dominion of Canada, and aresident of Toronto, Ontario,

Canada, (whose post-oiiice address is 406 Parliament street, Toronto, Ontario, Can

ada,) have invented a new and useful Improvement in Self-Releasing Lid supports, which invention is fully set forth in the following specification. I

This invention relates to automaticallyreleasing lid-supports for boxes or the like.

-The object of the invention is to provide an improved device of this character, by which upon merely raising the lid or cover of the box orthe like, the same will be automati-.

Cally held in itsraised position; and, thereafter, the lid can be lowered (as by one hand) by merely raising the. lid a trifle higher and thereby automatically releasing the catch so that the lid can be lowered freely.

Broadly stated, the invention consists of providing in the usual rigid bar (constituting the lld-prop) a longitudinal slot having a seat adapted to engage a stationary support carried by the box, and mounting upon said bar, adjacent said seat, a pivoted dog which permits the engagement of said seat and supphrt when the lid is opened, but prevents en agement of said parts while the lid is being lowered; The invention consists further in the features of construction" and arrangement hereinafter set forth and claimed. Alt ou h the invention is susceptible of embodlmentin various forms, it Wlll be best understood in connection with the following detailed description and the accompanying drawlngs, which set forth Wlll. be'swung partly around (toward the one preferred embod ment.

In the drawings Figure 1 1s a perspective of a conventional box or cabinet equipped with the preferred form of the present inbetween the seat and the support, and in dotted lines the position preliminary to lowering the lid; and i Fig. 3 is an end view of Fig? 2.

In these drawings 1 represents a box, cabinet, trunk, or the like; and 2 the lid or cover or top hinged thereto. 3 is. a rigid bar, constituting the lid-support; it is pivoted at its upper end to the lid, as at 4;, and has the elongated longitudinal slot 5 in its lower portion. 6 is a headed stud, located in slot 5, and secured rigidly on the inner face of one of the sides of the box, as 7, near the top thereof, to constitute a support. At a suitable point, preferably near the lower end of the slot, is a reentrant recess 8, to

constitute the support-receiving seat. A dog is pivoted upon bar 3, at a point 10, so as to hang down in such position aspractically to cover the recess 8. The lower end of the dog is slightly concaved, and the corner 11 ("on the side toward the pivoted end of the bar) is somewhat prolonged, so als to project beyond theseat 8 and into the s ot 5. a

As the lid 2 is raised, the seat 8 comes opposite the support 6, and will readily engage the same upon thevery slightest lowering of the lid,whereupon the lid is held securely propped open. In order to close the lid, the latter is first raised a slight distance farther, sufficient to. carry the pivoted dog 9 up past support 6, and then lowered' At that moment, the relative position of the dog 9 and seat 8- beforejhislowering) is indicated in dotted lines in Fig. 2. It w1ll be seen that, upon thus lowering the lid, the

recessed lower edge of the dog. and its nose 11 will engage upon the stud 6 and the dog left) until thestud has passed into the upper portion of the slot, thus preventing the stud from enteringthe seat, and thereby permitting the lid to be lowered freely the entire distance so as to close the box.

The invention has been thus described in detail, yet only for the sake of clearness since the invention is not limited to the preslot, and a dog pivoted upon said prop adcise construction and arrangement set forth, jacent said seat and protruding over said but may be embodied in a variety of forms. slot.
