BOX COVER FASTENER.

Specification of Letters Patent.

Patented Aug. 22, 1911.

Application filed October 31, 1910. Serial No. 589,865.

T 0 all whom it may concern:

Be it known that I, FREDERICK W. DoB- BEL, a citizen of the United States, residing at Sonoma, in the county of Sonoma and State of California, have invented certain new and useful Improvements in Box-Cover Fasteners, of which the following is a specification.

The hereinafter described invention relates to an improved means for the securing or locking of the cover to the body of crates for the shipment of goods generally, although its application is more particularly designed for use in connection with crates for the shipment or transportation of eggs; the object of the invention being the procluction of a locking device simple in its construction, inexpensive as to manufacture, which constitutes a permanent portion of the crate, and so arranged as to hold the cover securely against displacement during transportation of the crate, whether filled or emptied, and by so doing providing against the loss resulting by the breakage and damage to the covers by reasonof the rough usage to which articles of this character are subjected.

To comprehend the invention, reference should be had to the accompanying sheet of drawings, wherein' Figure 1 is a perspective view of a crate with the lock means applied thereto partly broken away. Fig. 2 is a longitudinal sectional view taken through the crate with the cover applied thereto. Fig. 3 is a detail view of the lock-bolt and its securing thimble or sleeve detached. Fig. 4c is a detail view of the thimble or sleeve with the lock-bolt assembled therein partly broken away.

In the drawings, the numeral 1 is used to designate the body of the crate and 2 the cover therefor. Preferably from the ends of the body of the crate upwardly project the lock or bolt plates 3, which when the cover is applied to the crate extend through the guide channels or cut out sections 4 formed within the said cover 2 and hold the cover against lateral play or movement.

In the present case, the cover 2 is illustrated as strengthened by means of the crosscleats or pieces 5, which are preferably secured to the upper face of the cover and when so applied serve to space a crate placed thereon. 7

Within a longitudinal bore 6 in each crosscleat 5 is fitted a split tubular metallic thimble 7 the spring pressure of which serves to hold the same firmly in place when forced within the bore, the inner end 6 of the thimble being flanged inwardly to slightly contract the same and its outer end formed with an outwardly disposed circumferential flange 7 which bears against the surface of the cross-cleat 5 and limits the inward movement of the thimble, likewise protects the surface of the said cross piece adjacent the bore 6.

Within the thimble 7 is fitted for longitudinal movement the lock-bolt 8, the re duced section 8 of which is surrounded by a spring 9, the same being confined within the thimble between the shoulder 9 of the lock-bolt 8 and the wall formed by the reduced inner end 6 of the thimble, which end is turned over or flanged after the lockbolt has been applied within the thimble, and said end is engaged on its outer face by the head 10 of the lock-bolt, which serves to limit the outward movement of the said lock-bolt.

The lock-bolt when held outwardly pressed its full distance fits within a bolt seat or opening 10 formed in the face of the lock or bolt plate 3, being locked therein 1 by the pressure of the retained spring 9,

which normally holds the lock-bolt outwardly pressed for projection beyond the thimble, the said lock-bolt being drawn inwardly out of engagement with the lockplate by pressure exerted on the head 10, which is intended to be grasped between the fingers and drawn outwardly to release the lock-bolt, and for convenience in manipulating the lock-bolt, each cleat 5 is formed on its inner edge surface with a segmental cutout 11 in order to secure clearance space in which to operate the lock-bolt. By this arrangement the head end of the lock-bolts is not required to project beyond the sphere of the cross-cleats 5 and to this extent the same are protected against being broken or damaged during rough handling of the crates. However, the lock-bolts may be operated in any desired manner, although preference is given to the construction illustrated and described, inasmuch as the lockbolts are not only protected but compactness is secured.

By the use of the described invention the cover may be quickly applied to and separated from the body of the crate, and held securely locked thereto when properly placed, which insures the return of the covers when the empty crates are shipped to the owner thereof.

In the present case the lock-plates 3 are provided with a transverse channel 12, so that in case one or both of the lock-bolts should become broken or damaged, a pin 1.2 may be slipped therein and thus hold the cover secured to the crate body, one of such pins being illustrated in Fig. 1 of the drawings.

Having thus described the invention what is claimed as new and desired to protect by Letters Patent is 1. In a fastener for shipping crates, the combination with the body of the crate, of

lock plates secured to the end walls of the said body and projected above the same, a

cover for the body provided with cut-outs or guide channels through which the projecting end of the lock plates extend, trans- I versely disposed strengthening cleats se-v cured to the cover, a metallic thimble fitted in each cleat, a lock bolt movable within each of said thimbles, a spring located within each thimble for acting against the lock bolt therein for maintaining the same outwardly and into locked engagement with one of the lock plates, and a head carried the lock plates extend, transversely disposed strengthening cleats secured to the cover, a metallic thimble fitted in each cleat, a lock bolt movable within each of said thimbles, a spring located within each thimble for acting against the lock bolt therein for maintaining the same outwardly and into locked engagement with one of the lock plates, and a head carried by each lock belt for drawing the same inwardly and out of locked engagement with its lock. bolt.

In testimony whereof I have signed my name to this specification in the presence of "two subscribing witnesses.
