THEODORE S. TOBEY, OF S QUTH NORWALK, QONNECTICUT.

BQX-FASTENER- To all ohom it may concern: Be 1t known that I, THEODORE S. Toner,

a citizen of the United States, residing at South Norwalk, county of Fairfield, State of Connecticut, have invented a ew and useful Box-Fastener, of which the followingis This invention has for its object to provide. a box or crate fastener adapted for general use in shipping food products and other articles of commerce and especially adapted for use upon oyster carriers where it is required that the carriers be strongly andsecurely locked against danger of coming open in transportation but at the same timethat they be capable of being opened easily and quicklyand without the use of tools when it is required to ice the contents of the carrier and as easily and quickly closed again.

With these and other objects in view I have devised the novel two member fastener which I will now describe, referring to the accompanying drawing forming a part of this specification and using reference char: acters to indicate the several arts:

Fi ure 1 is a partial elevation of one side of a ox illustrating the a plication of my novel fastener thereto, the astener meinbers being in the locking position; Fig. 2 a seetional view of the box and cover i strating the same fastener'member in s de elevation;

' Fig. 3.21 view corresponding with Fig. 1,

' member A and a fastener member B posite sides of the box near each end.

showing the other side of the box with the other fastener member applied thereto and in the locking osit'ion; Fig. 4': a sectional view showing the fastener member of Fig. 3 in side elevation; and Fig. 5 is a section of a box and cover at right angles to the section lines of Figs. 2 and 4, bothfastener members being shown in the unlocking position.

1O denotes a box, crate or carrier and 11 the lidtherefor. Eitherthe box or the lid may be provided around the edge with a strip of felt or rubber indicated by 12 in order to make a carrier air-tight.

My novel fastener comprises two members indicated respectively by A and '3. Either one or two complete fasteners'may be used on a box, crate or carrier; that is, a fastener on op- An number m'a of course be used but twowi l cured'to the lid by screws or in any 'suitable s ecification of Letters Patent.

manner and is provided with a hook-shaped catch 14 which hes on the edge of the lid. 15 denotes a plate secured to the side of the box, plate or carrier, by screws or in any suitable manner, in vertical alinement 'with catch 14 and provided with a lag 1.6 to which a lever 17 is pivoted, or fulcrunied as at 18, the forward end of the lever being preferably bifurcated and straddling the lug. 19 denotes a double link the arms 01 side pieces of which are pivoted on opposite sides of the lever as at 20 outside the pivotal point or fulcrum of the lever, that is, toward the free end thereof. At the upper end of the link is a downwardly and inwardly inclined cross-piece 21 which is adapted to engage catch 14 and make a lockin connection therewith. The operation of this member of the fastener will be obvious from Figs. 1, 2 and 5. When the lever is swung upward away from the side of the box as in Fig. 5, the link may be readily disengaged from the catch. To look the box, the cross piece is placed in engagement with the catch as in Fig. 5 and the lever swung downward to the locking position as in Fig. 2, the loop being in practice made wide enough to receive the catch between the arms or side pieces thereof.

In order that the.covcr may be drawn down tightly upon the box, crate or carrier I on both sides thereof so as to provide an airtight joint as is desirable in ovstcr carriers and boxes and crates generally for food products and also to permit the lid to be swun backward entirely out of the way as would not be possible with hinges, I provide member B which differs from member A in that the link, indicated by 28, is pivoted to the lid instead of being detachable therefrom. 22 denotes a plate which is rigidly secured to the lid by screws or in any snitable manner and is provided with an e e 23 which extends over the edge of the 1i and in which the-cross piece of the linkoscillates freely. It-will ofcourse be obvious however that the special mode of pivoting the upper end'of the link to the plate on the lid is not of the essence of the invention. 24 denotes a late rigidly secured to the side of the box y screws or in any suitable manner in vertical alincment with the plate on the lid. This late is provided with a lug 25 to which it ever 26 is pivoted or inlcrumcd as at 27, substantially in the icr member.. The link 28 is a douhie in the other member and the arms or side pieces are ivoted on opposite sides of the lever {LS at '29 outside the pivotal point or fulcrum of the lever as in the other form.

- j The operation of member B will be ob v ons from Figs. 3, 4 and 5.

To loosen-the cover or lid and lift it forc bly from the -paoking 12, the lever is swung upward as in-Fig. 5 and to tighten the cover the lever ism Figs. 3 and is sivung'downward to the locking position Having thus described my invention, I elai1n:- v

1. he combination with a box and its cover, of means for clamping opposite sides of the cover in place, the clamping means at oneside comprising a lever pivoted to the side of the box, and a link having a perma- "nent pivotal connection to the lever and to the cover whereby the latter may be forcibly raised by the lever through the medium of the link.

' Q senate 2. A fastener of the character described consisting of members each comprising a plate adapted for attachment to a box and iaving a lug, a lever pivoted to the lug and i a link pivoted to the lever outside the pivotal point to the log, and plates adapted for attachment to a lid, one of said plates having a permanent hinge connection With the link oi one of the members.
