BOX-COVERING MACHINE.

Specification of Letters Patent.

Patented Feb. 25, 1913.

Application filed August 14, 1809. Serial No. 612.883.

To all whom it may concern:

Be it known that I, SAMUEL Maononann Lanos'ron, a citizen ofthe United States, and a resident of Camden, in the county of Camden and State of New Jersey, have invented a new'and Improved Box-Covering Machine, of which the following is a full, clear, and exact description.

This invention relates to machines for a plying paper covers to boxes, cartons or he ike, and severing the covering into sections, each section being sutlicient for a single box or carton. In machines of this character it is customary to provide a rotatable support or form' for the box or carton and to deliver the covering material past a cutter to the support or form. The support or form is usually adjustable in rcspectto the cutter so as to vary its distance therefrom, and the cutter is ordinarily operated intermittently so as to subdivide the covering material into sections of uniform length.

v One of the main features of my invention involves the supporting and rotating means for the box support or form, so that the position of the latter may be adjusted at will without interfering with the continuous and uniform rotation.

A further feature or my invention relates to the mechanism for operating" the cutter automatically in proper synchronism with the box form or manually and independently of the box form.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which simllar characters of reference indicate corresponding parts in all the figures, and in which- Figure 1 is a side elevation of a machine constructed in accordance with my invention; Fig. 2 is atransverse section on the line 2-2 of 'Fi 1; Fig.- 3 is a section on the line 3-8 0 ,Fig. 1; and Fig. 4 's a longitudinal section through the spind e of the box support or form and showing the operating means for the latter, said section being taken on the line 4-4 of Fig. 1.

In the specific form illustrated, I employ a body portion or table 10, supported upon suitable legs 11 and having a power supply c length thereof and below the top. Adjacent to one end of the table and mounted in suitable bearings in the table to is a shaft 13, hereinafter referred to as t e main shaft. This shaft has a worm wheel 14, shown in dotted lines in Fig. 2, and meshin with a worm 15 on the power shaft 12. be main shaft 13 is thus continuously rotated at a comparatively slow rate of speed. Rigidly secured to the table and extending outwardly therefrom is an arm 16, for supporting the box form and operating mechanism for the latter. This arm preferably has one end encircling the shaft 18, and closely adjacent the arm and secured to the shaft is a sprocket wheel 17 and a cam 18. The sprocket wheel serves to transmit motion to the box form and the cam serves to o crate the cutter. The cutter is adjustable to varying elevations in respect to the table, said cutter being preferably mounted upon the upper end of a vertica ly disposed rod 19. At the uppcrcnd of the rod is a head or cup 20, raving oppositely-disposed brackets 21 and 22. The racket 21 carries a stationary cutter blade 23, while the bracket 22 carries a rock shaft 24. The rock shaft carries an arm 25 having a movable cutter blade 26 and an arm 27, by means of which the rock shaft may be oscillated. The material to be cut passes over the stationaryblude 28 and is subdivided by the lowering of the cutter blade 26 past the ed 0 of the stationary cutter blade.

or oscillating the rock shaft 24 to automatically or manually raise and lower the movable blade, the table is rovided with a bracket 28, to the up or end of which are pivoted two bell cran levers 29 and 56. Thelever 29 has a handle 57 at its front end, and intermediate the handle and the pivotal support. of the lever, said lever is pivoted to an upwardly-extending rod 80.

'Ihe upper end of this red is pivotally connccted t0 the arm 27 of the rock shaft, so that as the handle 57 is raised or lowered, the movable cutter will be simultaneously raised or lowered. The connections between the rod and the arm 27 are such that the rod is normally locked against longitudinal movement in respect to the arm but may be readily adjusted longitudinally in respect thereto. The two bell crank lovers are closely adjacent each other and both have.

forwardly-extendin arms and downwardlvextendin arms. he handle 57 is on the forward y-extending arm of the bell crank lever 29, while on the forwardly-extending arm of the bell crank lever 56 t ore is provided a roller 81 in the plane of the cam 18,

so that the roller follows the periphery of "wardly to operate the cutter, an

the cam during the rotation of the latter. The depending arm ,58 of the bell crank lever 56 has a forwardly-extending extension 59, from .the forward end of which a coil spring 60 extends rearwardly to the depending arm 61 of the bell crank lever 29. The ends of this'spring are so connect-' ed to the two levers that its tension may be adjusted at will, and the spring "is of such character that it tends to draw the arm 61 forwardly and the arm 68 rearwardly. A stop 62 on the arm 58 limits this movement, so that the two arms normally remain in the same relative position as shown in Fig. 1. The major portion of the periphery of the cam lies in the arc of a circle of such diameter that the cutter blade 26 is normally raised to its limiting position, but at one point of the periphery of the cam there is a substantially radially-disposed face 32 which permits the roller to dro downalmost immediately thereafter raises the cutter to its former position.

It is evident that any raising or lowering of the roller is communicated directly to the cutter, as the two bell crank levers are nor mally held against relative movement by the spring 60 and stop 62. If the paper he of uniformly good character, the mechanism will operate substantially as though the roller 31 were mounted directly on the lever 29, but in practice, it is found that there is often had places in the paper which have to be cut out. To accomplish this, the cutter is free to be operated independently of any movement of the cam. By pressing down on the handle 57, the cutter 26 will be operated even though the bell crank lever 56 and its roller remain stationary. The downward movement of the handle 57 merely extends the spring 60. and as soon as the ban-- die isreleased, the spring immediately raises the cutter to its normal position. The cutter thus operates automatically at every revolution of the box, and may also be worked manually at any time desired, irrespective of the position of the box.

The arm l6 which extends outwardly from the' end of the table, c'arries at its outer end a transverse shaft 33 and an adjustable arm or frame 34. Loosely mounted on the shaft is a sprocket wheel 35, which maybe locked to the shaft by a clutch collar 36 on the outer end of the shaft. A chain 37 connects the sprocket wheel 35 with the sprocket wheel 17 on the main shaft, so as to continuously rotate said sprocket wheel 35. but the shaft 33 may be rotated to vary its angular relationship in respect to the cam 18 by pullingout the clutch collar 36. The shaft 33 isnot journaled directly in the outer end of the arm 16 but is journaled in a sleeve 38 extending trans-- verselythrough the arm. The sleeve termithreaded on to the sleeve 38 opposite to the clamping arms and by tightening this nut the sleeve may be drawn longitudinally through the arm 16, so that the clamping arms 39, 39,- will bind the arm or frame 34 against the side of the arm 16 and lockthe two rigid in respect to each other. This nut may be provided with an outwardlyextending handle 41 to facilitate'therota tion thereof and permit the arms 16 and 34 to be quickly adjusted in respect to each other.

The frame or arm 34 is formed of two opposed substantially channel-shaped members 42, 42, connected at their upper ends by a journal box 43 and at their lower ends by a transverse member 44. Mounted in the journal boxes is the spindle 45.01? the box support or carrier, and upon this spindle is a sprocket wheel 46. Upon the-shaft 33 is a sprocket wheel 4.7- in the plane of the sprocket wheel 46, and at the lower end of the frame 34 and adjacent to the transverse member 44 there is a sprocket wheel 48 carried in vertically adjustable bearings. A chain 49 extends over the sprocket wheels 46 and 48 and engages with the sprocket wheel 47. It may be retained in engagement with the latter by a.small idler 50, shown in dotted lines in Fig. 1. The bearings of the lower sprocket wheel48'are carried by a journal box 43 may carry-a covering 53 over the sprocket wheel 46, the side members 42 of the arm 34 may carry .a side plate 54 and the arm 16 may carry a casin 55 over the chain 37 and its sprocket whee s. The spin- (He 45 which carries the box form or boxsupport, may be adjusted longitudinally through the upper end of the arm'34 by llp'osening a'c'ollar 63 shown particularly in ig. 4. I

Any suitable box support or box form may be secured to the spindle 45, so as to retate therewith. The specific construction of the box form or support constitutes no portion of the present invention, it being understood that any construction may be employed for supporting a box substantially as illustrated in dot-and-dash lines in Fi 1.

During the operation of the mac inc power is transmitted from the main shaft through the chains 37 and 49 to the spindle,

so as to rotate the latter and wrap the box covering upon the box. The cutter intermittently descends to subdivide the covering into sections of appropriate length for the box being covered. The distance to which the cutter blade is raised may be varied by varying the adjustment of the rod'30 and the arm 27, and the position of the box form in respect to the cutter may be readily varied by swinging the arm 34 about the shaft 33 as a center or'by bodily raising or lowering the arm 34 in respect to said shaft. An

adjustment of the position of the spindle 45 does not necessitate any adjustment whatsoever ofthe driving means for the latter automatically adjusts itself during the movement of the arm.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
