Application filed June 7,1910, Serial Iva 565,522. Renewed April 27, 1911. Serial No. 623,642.

; B e-it known that I, OHARLESdVl Bor'rnre FIELD, a citizen of the United States, resid'- ing at Bellows Falls, Vvindham county, in

the Stateof'Vermont, have invented certain new and useful Improvements in Machines for. Facilitating the Sealing of Package- Cases; and I do hereby declare the following-to be a full,'clear, and exact description of'the same, reference being had to the ac- .companying'drawings,i forming a part of. this specification,

and to the figures and-letters of reference marked thereon.

The object of. the present invention is to provide an apparatus for facilitating the sealing of the bottom and top flaps of cor- 'rugated and fiber .cases such as are em- I ,ployed for containing package goods, such arrangements of parts, all as will be now described and pointed out particularly in the as bottles or cans of olive oil, or other cor modities. a

A further object of the invention is to provide an apparatus which may be readily adjusted and adaptedfor use in sealing cases of varying size and. shape.

The invention I consists in certain novel details of construction and comblnatlons and Ppendedclaims;

Referrmg to the accompanying, draw in Fi re 1 is a ers ective view of'a-u apparatus embodying the present improve ments, portions of-some of the cases shown sea-led. Fig. 3 is a diagrammatic detail, v40

' in 'connect'iontherewith, being broken away to illustrate more clearly, the operation of the apparatus. Fig. 2 is a detail perspective viewof one of the internal forms em ployed for supporting the flaps whilebeing illustrating ,themeans for adjusting the clamping members for 'cotipe'ration withpackage cases of different sizes.

Like letters ofreference indicate the same parts in all of the figures.

The apparatus of the present invention embodies a-relatively low table or (benchlike support A for the package cases and in' the preferred form of machine illustrated in Fig. 1 thesaid table or supportis made double or of suiiicient Width to support'two 7 rows of cases, one row being located on each case positioning walls B and end standards side of a central diyision having upright O. The end.; standards C form guideways for a truss frame or clamp carrier D, said clamp carrier being guidedby end tongues standards. The frame or carrier D is vadaptved to be held in its adjusted position verti-' cally of the standards by any suitable means of well-known character and the retaining.-

means may conveniently be the means wherebyit may be adjustedin parallelism with (Z working in vertical slots or ways 0 in the.

v Specification of L etter s Patent. Patignfigd une 2'3; 1911 the table or bench. As shown, it is m0unt-- ed on verticallyarranged adjusting screws E located at each end-of the table and adapted to be simultaneously rotated by beveled gear connection with a horizontal shaft F, toone end of which acran'k handle 1 may be applied as shown in Figs. land 3.

A series of clamping members G are pivcarrier D, preferably by hinge connections otally attached at one edge to-the frame or which will permit of their being separated I for the substitution of different sized .orv

shaped clamping members and each clampmg'member embodies a handle or projector lowered, as desired. In addition, each clamp embodies a means whereby" it may be held down in its operative or clamping position, such means conveniently embodying ,a

7 ing part 9, whereby the clamp may be raised downwardly extending latch H adapted to be advanced by a spring h and having on its inner face a toothed edge or barI, the

teeth of which codperate with a catch pr tooth on the edge of the table or bench. The

tooth or catch member with'which-the latch onthe'c'lamp engages maybe conveniently formed by'a metal bar K secured in slightly inclined position along the edge'of the table orbench, thus serving as the 'means for retaining the latches of all the clamps on one y side of the apparatus.

It will be understood, of course, that where the machine is made double or adapted to handletwo rows of cases the parts will be duplicated onopposite sides and the number of clamping members employed is pref-' erably sufficientto enable an operator to work, continuously without having to wait for thesealing medium to dry, as will be presently explained;

For the purpose of supporting the end i flaps of the cases before the packages are placed therein, internal forms are provided,

preferably of the shape and construction illustrated in Fig. 2 wherein it willbe seen that each form embodies a platen like face L upon'which. the end flaps may rest and a 'web L which is of a proper width to correspondto' the internal depth of the case being I sealed; .This form is conveniently provided 'with hand holes -Z to facilitate its insertion and removal in the operation of the appzr -ra-tus.' Thepackage cases which are primarilylintended to be. handled by the apparatusare'ofthe' knock-dovtn type and are formed "of corrugated-or plain fiber, each case havwhen the caseis set up for use.

ingend flaps which fold in In operating with the apparatus, the end eflaps at one end of the case are firstfolded 1n and the case set on the table or bench v with the unfolded fla s uppermost. A. form such as is shown in and as shown 1'11 Fig. 1 the end flaps folded ig. 2 is then inserted in: Sealing material such as silicate of sodis then applied to the proximate overlapping faces of the flaps and \the clamps are brought'down to hold the flaps with the desired pressure until the sealing material sets. The operator proceeding in the manner de- 'scribed and having sealed the' flaps of the cases along both sides of the apparatus then releases the clamp of the case first sealed,

invert-s the case on the table, opens the unsealed flaps, removes the form from the case.-

and inserts the packages 'to be held by the filled by thefpackages and said'packages' case. The cases are of proper size to be justwill, therefore, support the endfiaps'when the latter are folded in and sealing material applied to the overlapping faces. With the 'packages'in place and the flaps folded in,

' the clampiis then brought down with the desired degree of pressure and the same order- -of procedure is followed in connectlon inth the next case.

In Fig. 1 at the point. indicated by the letter 0 one of the cases has its side wlall broken away to illustrate the posi on of the. packages therein thus, showing the 0 er,

ation of the clamp in, sealing the end aps which are closed after the packages are ha sorted, while at the point indicated .by the letter P one of the packages is shown broken away to illustrate the position of the, internal form for supporting the end flaps which and oye'rlap are closed and sealed before the packages are inserted The provision of'a toothed. bar 'or rack on the latches permits of the regulation of the pressure on the end flaps to suit the particular requirements of the case being sealed and, furthermore, does not require any adjustment to properly coiiperate with its catch when, the supporting bar or frame is adjusted vertically to suit the height of clif- .for each case or by substituting longer clamps for those illustrated.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent of the United States is handled by making use of two of the clamps 1; In an apparatus for facilitating the sealing of end flaps of package cases, the combinatlon -W1tl1. tl16 case supporting table having acase positioning rear wall and a clamp supporting frame above said well, of a plurality of clamps pivotally connected .With said frame, individual toothed latches for the clamps and means for temporarily supporting the end flaps of the cases hile being held by the clamps.

2. In an apparatus such as described, the

combination of a table having tlie end standards: thereon, the clamp supporting frame movable'yertically in said standards,

means for holding said frame-in adjusted' amps pivotally connected with] position, said frame and extending on .opposlte-s'ides thereof,- and individual latches for holding said; clamps in clamping position.
