UNITED STATES PATENT orrion WILLARD E. SWIFT, OF WORCESTER, MASSACHUSETTS, .ASSIGNOR TO UNITED STATES ENVELOPE COMPANY, OF SPRINGFIELD, MASSACHUSETTS, A CORPORATIQN- 0]? MAIN E.

To all whom it may, concern:

Be it known that I, VVILLARD E. a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Machines for Inclosing Flat Articles, of-

which the following, together with the accompanying drawings, is a specification.

The present invention relates to a machine for inclosing flat articles, and more particularly to a machine for forming an enveloping inclosure around individual paper drinking. cups, whereby the same may be presented'to the user in a sealed package.

The invention resides in the combination and arrangement of parts whereby. the cups or other flat articles are successively taken anlsm'of an "ordinary envelop machine, making suchchanges in and additions thereto as are necessary to the accomplishment of the required operations. However, it is to be understood that my invention is in no sense limited 'to the employment of such prior art envelop machine mechanisms as are herein illustrated, but is susceptible of wide variation therefrom as regards the several instrumentalities Which'operate upon the enveloping Wrapper or blank, to gum,

crease, fold and transfer the same, as well as the instrumentalities which operate upon the articles to be inclosed.

Referring to the accompanying drawings,

"Figure 1 is an end view of a machine embodying my invention, certain parts being broken away.and others being shown in section. 3

Fig. 2 is atop plan view of so much of said machine as is necessary to illustrate the principles-underlying my invention.

Fig.3 is a side view of said machine, some Specification of Letters Patent.

SWIFT,

MACHINE FOR INCLOSING FLAT ARTICLES;

of the well known envelop machine mechanisms therein being shown either diagrammatically or else omitted altogether.

Fig. 4 is a fragmentary side View of the plunger of my machine, and

Fig. 5 is a plan view of the product-0f the machine, the completed envelop or package, with the flat paper drinking cup contained therein.

Similar reference characters refer to similar parts in the different figures.

The illustrated embodiment of my invention involves ordinary envelop machine mechanisms of well known construction, for gumming and folding the blanks which are used for inclosing the paper drinking cups, and for conveying the same successively from the. gumming to the folding mechanisms. The mechanisms are supported on a table 1, at the rear end of which the usual feed board 2,'Fig. 3, for the pile of blanks 3, is provided. In the manner common to ordinary envelop machines, reciproeating gumming dies 4 and 5, above said pile of .blanks, descend into contact with the uppermost blank thereof, and raise it by adhesion, said blank being removed therefrom' by the usual stripping plate 6, Fig. 2, and deposited upon a horizontally reciprocating carriage 7, running on guides 8; The blank is held downonthe carriage 7 by a hook or gage 9, or by any of the equiva-- lent means commonly employed for this purpose in envelop machinery, said'blank, as it rests on said carriage, as shown in Fig. 2, disclosing on its front and rear edges the moist gummed

portions

10 and 11 resulting from its contact with the and 5.

Mechanism well known in envelop machines, and' hence not herein illustrated in detail, is employed to supply gum to the Patented Mar. 9, 1920. Application filed August 30, 1916. Serial No. 117,?69.

gumming dies 4- with the frame of the machine, said pins serving to center and accurately position the blank upon the carriage 7, so that the rectangular body portion of the blank is in exact registration with a rectangular opening 14 in said carriage of the same size, and

also with a rectangular plunger 15, which at the proper time descends and forces the blank through said opening, in the manner common to envelop machines. The blank thus registered is in position to have deposited thereon the cup or'otherarticle to be inclosed, by the mechanism hereinafter particularly set forth.

The table 1 supports a standard 16, used to carry a cup holder 17, at one side of the forward osition of the carriage 7 From near the hottom 18 of said on holder rises a plurality of

cup guiding ngers

19, 19, arranged to define a vertical space corresponding in cross section to one of the cups, as shown in Fig. 2, whereby the cups are supported in a stack, with their closed lower ends facing the plunger 15 and carriage 7. The lowermost cup of the stack rests upon the inturned

ends

20, 20 of an equalizing bar 21, pivoted at 22 upon a slide 23 which'is adapted to reciprocate in a slideway 24 of the bottom 18.. The cups are stacked so that their shorter sides face downward in the holder, whereby the ends or prongs 20, 20 of the bar 21 engage the edge of the shorter side of the lowermost cup, at the open end thereof, and move said cup to the left, Fig. 1, when said slide is actuated. The bottom of the slide carries a .cam roll 25, which is held against a cam 26 on the carriage 7 by means of a spring 27 whose force is exerted to draw the'slide to the right, Fig. 1. The movement of the slide to the left, by means of the cam 26, pushes the lowermost cup, through the slit 28, and for the purpose of preventing ejection of any but the lowermost cup, at each reciprocation of the slide,

adjustable spring fingers

29, 29, to separate the cups, are preferably employed.

Each cup so ejected is moved by the slide into the engagement of constantly driven

rolls

30, 30 adjacent the plunger 15, which are rotated by gearing 31, 32 and 33 from the main shaft 34 of the machine. The

rolls

30, 30 move the cup in a horizontal plane at the level assumed by the plunger 15 when in its uppermost position. As the

rolls

30, 30, must necessaril be located outside the path of the vertical y reciprocating plunger the quick action of the rolls are caused to impart sufiicient momentum to project the article passing between them clear of the rolls and into position beneath the plunger.

The under face of the plunger has a recess 35 slightly larger than and corresponding in shape to a cup, the walls of said recess being grooved, as at 36, to receiveeach cup as it leaves the

rolls

30, 30. Preferably a pair of

hooks

37, 37 are employed, just below the recess, to prevent endwise displacement of a cup therefrom, once it has been received within the recess and, if desired, a spring or wire 38 may also be used to prevent rebound of the cup after it has struck the opposite side of the recess.

Normally seating against the underside of the plunger 15, within the recess 35, is a secondary plunger 39, whose rod 40 is telescoped within the rod 41 of plunger 15. The

plunger 39 is held retracted by springs 42, attached at their upper ends to the rod 41, and at their lower ends to pins 43 projecting from rod 40 and passing through slots 44 in rod 41, which enable relative movement between the plungers to take place. In order to insure quick movement of plunger 39, and to prevent imprisonment of air between the two plungers, each of the latter is referably perforated as at-45.

he plunger rod 41 is attached to an arm 46, the latter having a vertically reciprocating movement in a slideway 47, which is formed on a stationary standard 48 rising from the table 1 of the machine. Pivoted on said arm is a lever 49, one end of which is adapted to strike an adjustable stud 50 on the standard 48, to rock said lever, when the plunger 15 is approaching the end of its downward movement. The other end of said lever is held yieldingly against the end of a sleeve 51 by means of a spring 52, said sleeve receiving a rod 53 whose lower end seats against the end of secondary plunto force the cup out of recess 35, and onto the top face ofthe blank.

In the operation of the mechanism, the cup is fed to the recess 35 of the plunger 15 as above described, with the plunger in the position shown in Fig. 1, and with the plunger 39 of course retracted as shown. In addition to the support afforded by the groove 36 of said recess, the cup may be kept from sagging oted skid 55, carried upon the gage bar 13 and held in operative position, as shown in Fig. 4, by a spring 56, against an adjustable stop 57, whereby the cup, when the plunger 15 is at the limit of its upward movement, is insured against dropping out of the recess.

Assuming that a gummed blank has beenmoved forward by the carriage 7, and

. rests directly beneath the plunger 15, in the at the center by a pivcommon to the operation of envelop machinery, through the opening 14 of the carriage 7, and this action creases the several flaps of the blank along the desired'lines of fold indicated in Fig. 2; As the plunger descends, its edge, and ultimately the bar 58 rising therefrom, make contact with the pivoted skid 55, to carry the same into the dotted line position of Fig. 4, away from the cup and out of the path of the plunger. The further descent of the plunger beyond the opening let carries the creased blank into the folding well or bed 59 of the machine. Just prior to the arrival thereof upon the bottom of the bed, the end of lever 49 strikes the stud 50, causing the secondary plunger 39 to push'the cup out of recess 35, and against the blank, which immediately thereafter is deposited in the bed 59 by plunger 15. Thereupon after the upward movement of the plunger, the four hinged

flap folders

60, 60 of the folding bed are actuated, in the manner well known in envelop machinery, to turn down successively the creased flaps, causing their gummed edges to adhere, as shown in Fig. 5, thus providing an enveloping inclosu're around the cup. The package thus sealed may be then discharged in the usual manner common to envelop machinery from the folding bed 59.

It will be noted that the folding mechanism above referred to is in all respects the same as the mechanism for folding ordinary envelops, except that the last flap folder 60 to operate turns the flap 61 completely down, whereas, in an envelop machine this flap is only partially turned down, and constitutes the open seal flap of the envelop. The machine, therefore, is adapted also to make ordinary envelope, merely by reducing, by a simple adjustment, the movement of this final flap folder 60, and by render ing inoperative the cup feeding mechanism. This last may be conveniently accomplished by a stop 62, onthe end of-a lever 63, which is held in the position shown in Fig. 3 by means of a spring 64., A rod 65, attached to said lever, may beoperated to rock the lever, thereby moving the stop intothe path of the slide 23, when the latter is in ad vanced position, and thus preventing the spring 27 from retracting said slide. A latch 66 may be employed to hold the rod in the position described, against the force of spring 64:, so that no cups are fed, and furthermore this mechanism, it will be seen, enables the supply of blanks on the feed table to be replenished at-any time, without stopping the machine.
