C is a shaft located in suitable bearings at the top of the frame, and by means of which motion is given to the several parts of the-- machine; Said shaft is provided with two main cam-wheels D and E,-by which motion 713 is given to the several parts of the machine.

G is a vertically'movable die. or plunger ar-. ranged in guides b b'upo th machine fmme l and vertically over the form B t-L H is a secondary plunger orstrip 'bender located at the rear of and, slidingupon; the

I is a lower die or anvil, which is supportedupon the form 'B'beneath the plunger G, and

against whichsaid plunger acts I in v the oper-. 8e-

ation of the machine to press or clampastaystrip against a box-corner interposed between the said anvil or dieand the said plunger. The upper surfaces '8 13 of the anvil-or die I are oblique and arranged atright angles with I each other, andthe upper die or' plunger is also provided with workiu faces- 1 g atright angles with each other an forming an. angm" lar notch or recess which fits over the die'or. anvil I, so as -to press equally upon the adjacent sides of an interposed box-corner; The oblique sides of the die or anvil I and theform B are preferably-made to approxinijatelgi coincide with each other, so tha teeth; of said parts minnow -support res i hox'i corner in the operationof' applying the: stay thereto. The die or anvil I is herein shown as made' of square formand thef bl'ock B as providedwith a V,-shaped'=-notch I; in its top to" receive said die; but this'particular shape of the said we notch 11 and of the lower part of theanvil is lobviouslynot essential, and they may. be. of any suitable shape; I The said anvil lis' herein shown as constructed to; move horizontally and as extending through a horizontal hearr05 ing-aperture a in the frame, by whichiit is 1 supported, a horizontal lllOVBlIlBllilbdll the said anvil to aid in turning ining the stay-strips to the inside of the borrcorner as will hereinafter appear.

atone sid'e ei the clamping-dies, and K a reel,

on,which is wound-a strip of paper or other fabric from which the stays are to be formed.

.0 is apast-ing or gluing roller mounted in bearings over and extending into thewell or reeeptacle J, and over which the strip passes from the reel K, and LLN are fetid-19 operating in connection with an elastic bedL to feed forward the continuous stay-strip from the glue-roller toward and between the clamping-dies, The saidelastic bed L consists of a series of parallel bars or wires Z Z Z, Figs. 11, 12, and 13, which are secured at their ends in the frame at either side of therollers M and receive the bars; or wireslll of the .Qlastic bed L, the "narrow annular flanges Q1 rib formed by said grooves projecting upwardly between said bars or wires, so as to bear upon the under surface of the stay-strip. The said roller N is shown as mounted in a movable frame N, sustained by'a spring-arm n, which holds the roller N against the stay-strip. A

cutting device for severing the continuous strip into pieces of suitable lengths to form the stay-strips or fastening-strips is located between the feed-rollers and the clamping dies, and consists, as herein shown, of a stationary blade or cutter P, securcdtothe chine franie at one side of the clamping-dies,-

and a vibrating knife or blade Q, pivoted 1 9 the said frame. ,Tlie stationary blade .oroutter P is herein shown as attached to an over hanging horizontal part A of the frame,

which projects forward at one side of the clampingdies, and on whiohthe lower feedroller N and elastic bed are supported, said part A being provided with arecess or open ing to receive said lower feed-roller and the movable frame" N'.- The movable knife or blade Q is shown as located between thestatlonaryblade and the clampin -dies-and as mounted on a pivot q; secured on the part A. ofthe frame. 1 I '7 Means are provided for actuating the several parts above described as follows: The

cam-wheel D is located adjacentto and at the rear ofithe plunger G, and the latter is provided-With a stud or roller 0, which engages with a cam-groove d on said cam-wheel,

Qtheldwer limit if its movemenhand with an inwardly-deflected part (1 which accomplishes the lifting and depression of said plunger. Said pl nger G is preferably divided transversely into two separate parts G and G,

connected with each other by a'sliding joint astand having between them rubber or other spriri'g G by means of which the lower portion of the plunger is adapted to yieldn wardly to a slight extent when broughtdown J is a-well or receptacle for-paste, located the box, thus preventing shock and iyof breakage and rendering the upper plunger adjustable to boxes of. diiferent thicknesses The secondary Plunger or strip-bender II, which; as h'ereinbeforestdtsd, operates in conneetion with the reciprocating die I for turning in the end of the s'tay-si ;rip,v rests and slides 'in a groove in the back of the main plunger G', Figs. 4 and 5, and is provided with projeption or shoulder g, adapted for engageinent with the cam-snrface 1) upon the rim of the camrwhee'l D. The said cam-wheel is provided at one part of the said cam-surface D with a cam projection 51?, which acts to advance or depress said secondary plungerH relatively to the plunger G at a desired time in the operation of the parts. The plunger H is retracted or drawn up and held in contact with the rim of the camv D by means of a polled spring h, whichaets upon the'plunger G; and said plunger H. In the particular construction illustrated the said coiled spring h is located in a groove of the secondary plunger H the lower end of the spring being attached to the secondary plunger, and the upper endrthereof. being attached to a pin h, which projects from the main plunger into the said groove. Y

I The horizontally-movable die I is provided at its rear end with a stud d, which rests in a cam-groovej in the cam-wheel E, said can1-.

. groove being located .in the outer or cylindric face ot-the cam-wheel, and being provided with ,a straight part e, which retains the die I. ts forward or operative position during, the great r t of the revolution of the cam, and'wi vardly-deflected part a, which moves said wardly or rearwardly, and then age 4.101. to its normal position to aceompl-Ts the to 1 s i of a rp.-

I The upper feed-r lo M is preferably cor-p m ated or ran on its 5 rface, an serves, in conuectwn .ith th el s i b L,- to early or feed the strip forward-over the said elastic bed. The said upper roller is-operated by means of a segmental gear E on'the camwheel E, which segmental gear'eng' es. with a cog-wheel m on the shaft of the roller M. Said segmental gear operates to urn'th teed- I "roller once at each rotation at theGmn-wheel' a distance sufli'cient to feed forward a part of strip. I v .The cutting devioefor severing the paper is actuated as follows: The movable blade or cutter Q is extended at its inner end past-its pivotal point, so as to form a projecting arm' Q, which is pivoted at its rear end" to a vertical slideR, which is held in the guide R' on.

the machine-frame and is adapted to move groove 2" of the cam-wheel E, which camgroove is so shaped asto actnatesaid movable blade at the propertime to sever the strip, and;

having for this purpose a concentric part c, 5 which acts to hold the. movable blade ele- -vated,a;nd an inwardly-deflected part e'gwhich acts to depresdand elevate the said movable blade for severing the strip.

The machine may be driven by any suitto able means, that shown in the drawings con sisting of a belt-pulley S, mounted on the shaft C andadapted for connection there with by means of a clutchs', which is connected with a treadle 'B- at the bottom of the r 5 machine. I

. The operation of the Tinach-ine, constructed as above described, is as follows: The con tinuous strip of paper or other fabric is drawn from the reel Kby. the feeding devices over the pasting-roller O, by which a suitable sup- 'ply'of adhesive materialis applied to the lower side thereof. 'The'strip is fed by the feeding devicesbetween the blades P andQ' f the cutting'device jand overthe boxcor- 21g 5hr resting on the form 13, and die I: at a time whenthe upper plunger is elevated and the die I is in its advanced or outward position, the

' gear-segment E being'so located as to engage l and operate the cog-wheel m, and thereby turn the feed-rollers, when the main plunger is held in its ele'vated'positiou by the engagel ment of the roller g with the concentric part.

11' of thetcam-grooved." After the end of the I strip has been advanced ove'r'tl e' box-corner the cutting device is operated to sever thestay from the continuous strip, and, the plunger G at the same=time desccndsand "presses the cut stripngainst the cornerof the box'and secures the same to thebox-walls o ateither side of the corner. The movable blade Q of the cutting device is actuated at the proper time by the-action 'of the'inwardlydeflected'part e of the cam-groove e, which isso located as to give movementto the said blade shortly after the feed-roller ceases to move; The descent of the plunger G begins about the time the said blade begins to move,

- p and the movement ot the blade is somewhatstationnry blade. In other'words, the movable blade and plunger move downwardly-at about thesame time and the plunger reaches? 6e the'level oithej strip about the timethat the, same is severed'by the cutters. Inasagpch as .the corner or-apex of a box resting uppn the f 1-gmnds. only slightly below the level o f-u h f stationaryblade, after .the strip has been 6 5 fodder-ward over the box-cornenitwili either 'fallupon and adhere to the boxcar or beforeit is severed from-the continuous strip.

or it will be carried downwardly against the box-corner by the descending plunger at the moment it is severed and before gravity has had time toact. In either case the liability of the severed strip being displaced after it is cut from the main or' continuous strip is obviated, it being obvious that if from the stiffness of the material used for the staystrip' the end thereof which-is thrust forward by the feed-rollers over the box-corner does not fall or bend by grav'ity,so as to bring its adhesive lower-surface against the box-corner, the advance edges'of the-descending plunger, acting against one orboth ends of the cut-off strip .at' the time the same is severed, will bring the middle 'of the strip immediately into contact with the box-corner, and thereby hold the strip in place until the'end portions of the stripare carried downwardly and pressed against the sides of the box.

The machine herein shown is, as hereinbefo're'stated, constructed toturn into the inside of theb'ox the-projecting end of the stay,

and'for this purpose the stay-strip is made of such width and its guides are soa'rranged that the inner edge of the strip extends over the stay is pasted down on the outside of the box-corner a loose or free end projects outward beyond the inner edge of the box. Af-

for past the edge of the box-wall, so that when I ter thcplunger-G has pressed the stay upon the box the secondary plunger orstrip-bender II thcu descends and bends or turns this loose end vertically downward," as shown in Fig. 8. This movement of the plunger H is accomplished by the action onthe projection d of the cam projection (Z of thecamsurface D.

The-secondary plunger then rises, and the die I, which-has withdrawn from the notch a while the plunger l-Iiwas descendiug'by'the action :of the deflected part c of the camgroove .e, moves forward again, and,- catching the .bent down end of the stay, thrusts the same inside of the box-coves and presses'itagainst the inside of the box, the upper plungerG meanwhile resting upon the boxcorner, so as to retain the latter in place during theiniovomentof the die I.

The operation of the parts in turning inthe strip is clearly shown in Figs. 8 and'9, Fig. 8

showing the die I 'du1'ing 'its.. .:forward move- :ment after the end of the strip has been car'- 7 ried inwardly and pressed against theinside o'ipthe box. During. the withdrawal of the are. I in the mamne tiiascribed the box-corner is sustained inp B, the incline 315 are arranged:

on'by meaus of the form which, as before stated, gnment with the workingta'ces of saidd e The main purpose ofrsaid form' B is to sue n th'e boi'acorner when the die I is withdrawn; bufisaitl-formfis herein shown as made solid and provided with a notch to receive the end of the die I, sothat the form serves as a support for the said die under the downward pressure of the upper die or plunger, but by making the lower die I of-sufficient strength or stiffness the use of the form B as a support therefor will not be necessary. 1 1

In many boxes the stay is simply pasted against the exterior surface f,the box-corner andis not turned in or over the edge of the same',inwhich case the work ,eanbe done by using anon-reciprocating angular lower die or anvil and a single upper die-or plunger- In such case the form B will obviously not be necessary as a part separate from the die; or,' in

J other words, a single lower die or form will take the place ofthe form 13 and movable lower die I. y In some cases a continuous stay-strip may be employed, which is covered or coated with 0 dry adhesive material, in which case water will be used in'the receptacle J and the roller 0 will operate to moisten the strip only.

As far as the main'features ot my invention areconcerned, forms other than those illustrated of the several-parts of the machine may be employed without departure from my invention-as, for instance, in place of the particular mechanisms shown for feeding or delivering fastening-strips or stay-strips to and between-the clamping-dies, or for applying paste or glue to the said stay-strips-- Qtherforms of strip feeding and pasting-Aevices may be used in practice with the same general result, as above described.

I claim as my invention- '1. The combination, with opposing clamp; tug-dies having diverging working-faces, of a feeding mechanism constructed to deliver stay-strips between said clamping-dies, and a 40 pasting mechanism for rendering adhesive so constructed the stay-strips, said clamping-dies being constructed to co-operatein pressing upon interposed box-coruers the adhesive stay-strips, substantially as described. v
