Application vlef August 14, 1914. Serial No. 856368.

dent of Dunedin.` in the county of .Pinellas and State of Florida, have made certain new useful improvements in Box Presses, ot

vwhich the following is a specilication.

My invention more particularly relates to a clamping press for the tops of crates used in packing and shipping citrons fruits such as oranges, lemons and grapefruit.

lt is well known to those engaged in packing citi-ous fruits that they are packed with a so-called bellied top, the fruit projecting somewhat above the upper edges ot' the crate over which the flexible top or cover is placed. and flexed downwardly so that the ends of the cover may be nailed to the crate, the cene trai portion or" the cover bulging outwardly and upwardly and disclosing the fruit along the sides. The object of so packing citrons fruits is to insure that there shall be no movement of the contents'o the crate during shipment, the yielding pressure of the flexed cover firmly holding the :fruit against all movement. In addition to securing the cover at the ends, it is customary to apply a boi: strap of metal or hickory, or other tough Wooden strip, transversely about the central portion of the crate and over the cover. Because the crate is packed with this bulging or bellied top, it is customary in packing houses handling citrons fruit to em- .ploy a box press having clamps to engage the ends of the cover and to draw them downward to contact with the upper edge of the crate at the ends .and to hold the cover in place whilebeing nailed or otherwise secured.

IThe object of the present invention is 'to provide a boxpi'ess having clamps so constructed and'operated that they will not interere with the handling of the crate and its proper positioning on its support, the clamps having such movements that when disengaged from the crate they are in a position whereby they will not interfere with the positioning of the crat A. further object of the invention is to so construct the operative instrumentalities that a free clearance space is provided and the clamping mechanism Willnot interfere with the positioning of the central transverse strap or band, and `whereby the strap or band may be positioned and applied without releasing the clamping devices trom the table B will be positioned at extending flange C which aords engagement with the top of the crate, there eing no part of the clamping mechanism interfere with the positioning and drawing of the box strapabout the crate or frhe movements of the hands "of the operator while applying the box strap.

To the above ends my invention consists of a box press comprising a support for the crate or box and with clamping members located at or near the ends of said support, and each providedn'ith independently operating mechanism to control the movements of the clampingmembers into and out ci' clamping position, and a common operating device for said' clamping members located below the surface of the table or support.

rMy invention further consists of the de -vices and combinations of devices which will be hereinafter described in the claims.

My invention is illustrated in the accompanying drawings in Which- Figure l is a perspective view illustrating my invention with a box in place upon the receiving table and the clamping members in inoperative position, Fig. 2 is a front elevation, partly broken away and in section, illustrating the clamping members in clamped position upon'l a box, Fig. is a side elevation, Fig. 4 is a horizontal section taken substantially on line 4 4 of Fig.

and Fig. '5 is a detail perspective vievv illi'istrating certain parts to be hereinafter specifically referred to.

^ The. apparatus as illustrated in the drawings comprises a suitable frame consisting of the' vertically disposed end frames A and the horizontally disposed receiving table B, the table B being rigidly secured in any suitable manner to the tops of the end frames A, and in practice the, end frames A will be bolted to the floor orv other support by the bolt-s a. The end framesv A are preferably of such height that when bolted to the floor a convenient height above the iioor to facilitate the positioning of the crate thereon as the same Yis taken from the end of the runway by 'table B is preferably smooth from end to end, and preferably along the back edge it will be provided with a narrow vertically a guidea'gainst which the rear lower edge of the carrying portion F and a elampm' portionl F1 extending from the upper end o the por- 'tion F and preferably disposed at right angles thereto. The clamping leversare each independently supported at or near the ends of the table B in such manner that they may have upward land downward movements for the purpose of causing the clamping portions F1 to move away from and toward the top of the box-or crate, and in the apparatus of 'the drawings they are so supported thatvin their upward and downward movements they will have a' movement backward and forward, away from and toward a vertical plane extending through the table B, so that the clamping portions F1 when released move upward andY backward out of the way of the operator leaving a free' clearance space for the removal and receptionof the crates'from and on the table B, andin the clamping movement they move inward and downward toward the top of the box or crate. The supporting mecha- 'v nism shown inthe drawings comprise links Gr which are pivotally lconnected yat theirv ends respectively to the lower forwardly extending ends of the carrying portions F and to the-side frames A as by means of the bolts g. The clamping members-are also connected to links I which at one end are pivotally connected-by means of the boltsz' to the ear rying portion F of the clamping members and-at their opposite ends by means of bolts L to upwardly and rearwardly extending brackets H projecting from the end frames A.

It will be noted that the supporting devices of each of the clamping members is entirely independent of the supporting del vices of the other clamping member, and that except for the operating mechanism which imparts the upward and downward movgment to the clamping members they are not connected with each other, and thus a freeand unobstructed space is provided be- -tween the clamping, members at the rear'of the table so thatthey will not interfere with i the manipulation and application of the box strap to the central portion of theicrate.

The operating instrumentalities which im` part vertical movements to the'clamping members include a reciprocatingcrosshead D? which carries a rod orl shaft E, and which shaft at each end engages an aperture f in the lower forwardly extending ends of the carrying portions F of the clamping members. The crosshead D2 imparts a si- -multaneous downward movement to the clamping members and for this purpose it is provided with a link D` which is pivotally connected at its upper end to the erosshead D2 and at itsV lower end pivotally connected to 'a foot treadle D1. The crosshead isdepressed against the tension of springs J, there being two such, springs which at their lower ends are supported by brackets j upon the inner faces of' the end frames A and at their upper ends engage and are connected .to lugs mprojecting from thelower ends of the carrying portions F. The springs J act to elevate the cross heads D? and the clamping. members F when the foot treadle is released. It is to be observed that the links G and are so positioned and so connected to the carrying portions F of the clamping l members that, when they are moved vertically by means of the crosshead D2 and thev springs J they at the same time move into and out of a verticalplane, and thus the Aclamping portions F1 are moved i'nto and out of a plane which will cause them to en gage the ends of the cover which is to be applied to the crate. It will be further noted that 'when elevated and moved out of the clamping plane, the clamping portions F1 are disposed in such a 'manner that a relatively large free clearance space is provided for the positioning of the crate on the table B,the clamping members where they project above the table being located en? tirely at the rear thereof` so that the crate may b e slid on to the upper surface of the table from one end as itis taken from' the conveyer which delivers the filled crates from the packing table. It will be further noted that the apertures f are flaring at each bers may adjust themselves to the height of the crate at the ends, even though there'be slight variations in height by means f this rocking connection of the crosshead D2 with the clamping members which provides for :t

limited independent clamping movement ofv the clamping members.

In operation a boxstrap` is positioned transversely on the table B and the crate placed thereon. -The flexible cover is then laid on the fruit andthe treadle D1 depressed, thus througlpthe link D imparting a downward movementv tothe crosshead D2, which by means of the shaft E causes a downward movement to the clampingmembers against thegitension of the springsJ, and as the clamping members more down-l ward vthey -are means zof the linksG and I caused to move irst'toward lthe crate or toward the table, so thatthe carryingv portions F are disposed in a vertical plane and the clamping portions F1 in a horizontal plane, and the further downward movement brings theclampingportions F1into con-v iis4 tact with the ends of thevflexiblfe 'cover de` pressing the ends over the fruitfffand bringing them into contact with "the yends o f the crate, in which positionthecover will be' clamping xieiiilscis While the cpnai the comfy io 'the wat@ :it die "fliciiiwi' flic upm-:swr 'sin .5: mixing )ing incur ,1 :slimsi'i iii in Fig. in), tlius l 1m'- spiiire for the a drawinff the en is i lic lmx sti-sisi) about lie craie, :mii fastening; it
