Application filed lletober 1, 1-923. 'Serial No. 665,788.

This invention relates to machines of the general type disclosed and claimed in Letters Patent No. 1,289,729, issued December 31, 1918, to Harrison 8. Gripe. The machine shown in said patent is designed for the purpose of applying paper or other covering material to the tops and bottoms of boxes whose sides and ends have previously been provided with a covering of similar material.

The present invention has for its object to generally improve the covering applying and pressing devices of a machine of this type, and more particularly to provide means for smoothing down any rough portions at the corners of the box due to the imperfect application of the side and endcovering, so as to cause the top andbottom covering to be perfectly smooth and fiat at these points; toprovide improved means for pressing the applied covering smoothly upon the box top or bottom, which pressing means is. of such a character as to permit the same I to adapt itself readily to inequalities in the work operated on; and to provide improved means for controlling the operation of said pressing. means so as to cause the same to engage the work at the proper time, said controlling means being adjustable to adapt the same to boxes of different sizes.

,The foregoing and other objects of the invention, together with means whereby the same may be carried into effect, will best be understood from the following description of one form or embodiment thereof illustrated inthe accompanying drawings. l t willbe understood, however, that the vparticular construction described and shown has been chosen for illustrative purposes merely, and that the invention, as defined by the claims hereunto appended, may be otherwise practised without departure from the spirit and scope thereof.

In said drawings:

simplified side elevation of the machine with the adjacent side of the frame removed and certain of the parts, not} essential to the invention herein claimed, omitted.

i Fig. 2 is a detail sectional viewtaken substantially on the line 2 -12, Fig. :1, illustrat ing the mounting off the pressing roller.

Figs. .3and a are enlarged side elevations,

illustratino the operation ofthe means for applying the covering material and smoothing the same at the forward edge or corners of the-box.

Fig. 5 is a detail perspectiveview of one corner of the box, illustrating the improper position of the covering material prior to the operation of the smoothing means.

Fig. 6 is a sectiofn on the line 6-6 Fig.

Fig. 7 is a detail side elevation 0 one of the heads which support the smoothing roller, the latter being shown in position therein. U

Except as hereinafter described, the machine herein shown, as to its general organ-i zation and the parts not illustrated, may, if desired, be substantially-as more fully shown and described in Letters Patent No. 1,289,- 729, above referred-to. 3 Said machine comprises a frame 25 provided with longitudinal ways in which is mounted ;for movement transverse to the covering applying and pressing devices, hereinafter described, the carriage 26 of a work support 27 having ahead 28 for supporting thebox b to be covered. The upper part of the head '28 preferably comprises a board 4 detachably secured to said head, whereby boards of different sizes may be provided for diiferent sizes of boxes to be covered. The carriage QT is reci-procated in its ways by mechanism which may be substantially similar to that shown in the Gripe patent above referred to, but which is herein shown as of the type disclosed and claimed in another application, filed Qetoher 1, 1923, Serial No. 665,789. For the purpose of the present case, "this mechanism may be described as follows: The'carria'ge :26 is formed at its under side with ears 30'co1rnected by links 81 with levers 3:2 suitably iulcrumed, as at 33, to the frame 25. Dieposed between the lovers 32 is a lever :34 fulcrumed at 35 to a bracket 36 secured to said frame. The levers 32 and 34 are formed with longitudinal slots to receive slides 37 pivot-ally connected, as at 38 and longitudinally adjustable in said *slots by means of mechanism generally indioated at 89 to adjust the operative connection of -the levers 32 and-34; and thereby vary the length of the-stroke of the carriage 26; The lever 34 is operated by a link 40 having acam roller 4-1 which cooperates with a "cam 42 on a camshaft 43 journalled in the frame 25, said link having a-f'orked endlembra'c- 251; j f' m ager;

This turning movement is yieldingly resisted by the spring 80 acting through the tension frame 86, the tension of the spring being increased by the downward movement of the arms 63. The smoothing roller 8 is also pressed against the work by the spring 82 which yieldingly resists upward movement of said roller in the slots 80. Said roller 8 is therefore yieldingly pressed against the work as it is moved outwardly there'over by the turning of the heads 76, thus flattening down the

portions

730 and 480 of the-cover-- ing material making a edge of the box. The maximum tension em erted by the spring 89 through the tension frame 86 upon theheads '76, as well as the normal position of the parts, is determined by the adjustment of the nut 95.

In accordance with the present invention, the pressing member 52 comprises a roller, pit 'efera bly provided with a rubberor peripheral surface, said roller being journalled at its ends in studs 1-00 slid-ably mounted in the-ends of arms T0 1 hale-ruined on the rod andoonnected by 'a cross anemher 102 to form a pressing frame. Within the ends of the arms 101 are springs 103 acting-to press the studs 100 outwardly and yield-ingly resisttheir inward movement, tilt-re movements of said studs being limited by lugs 104 secured, as by screws 105, to "said arms and extending through openings there- M1 into engagement with grooves formed as the studs. By means of this construction theroller 52 is pressed yieldingly against the work, thereby providing for an sure upon boxes of difierent quality and even pres compensating for variations in the thickness of the boards 4.

The arms 101 are operated through links 106 bylevers in the form of arms 1 07 "on a rock shaft 108 journalled in the framep25, said rock shaft havinganvarm 1-09 to which is-connected a link 11 0 supported by a link 111 from the shaft 58 and carrying a cam roll 6 cooperating with a cam 113 on the shaft 43. One of the lever"a1"-'rns 107 is connected by a link liw-itli alever 15 f' u'lorurrred -a-t1 6 on the frame 25 and formed with a bearing surface 17 which is engagedby aroller 18 on a bracket 19 mounted in longi tudinal ways 20 on the underside of the carriage 26' and adjustable in said ways longit-ud-ina lly of said carriage by means of adjusting screw 21 connectmg said oarneat fioint at this,

i on the bracket.

The arms I01 and pressingroller 52 are raised through the connectipns described by the cam 113, which is formed with a low portion 123 adapted, as the carriage 26 starts to move forwardly or towa rd the left in Fig; 1 to release .the roller 6 and place the arms 1 01 and roller 5-2 under the influ once-of gravity. Said armsa nd roller, however, are at this time held elevated by engagemen't of the roller :18 with the bearing surface 1 7 of the lever 15 which acts through the link '14, lever 10?, and link 106 to support said-parts until the carriage 26. in its "traversing movement, carries the. roller 18 out of engagement with said bearing surface '17, thereby releasing "the pressing roller and permitting "the same to engage the work. The exact time of engagement of the roller 52' with the work may, therefore, be accurately determined by adjustment of the bracket 19, thereby adapting the machine for accurate operation upon boxes of different sizes and shapes.
