ING MACHINE.

SPECIFICATION forming part of Letters Patent No. 758,502, dated April 26, 1904.

Application filed July 29, 1903.

To all whom it non/y concern: I Be it known that I, HENRY BAKER BLACKIN TON, a citizen of the United States, residing at Auburn, in the county of Androscoggin, State of Maine, have invented certain new and useful Improvements in Box-Covering Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. My invention relates to improvements in paper-box-covering machines. It is designed to cover the outside wall, a portion of the bottom, and a portion of the inside with a single strip of paper. So far as I am aware, it has been customary hitherto for the box-maker to turn the edge of the paper under the bottom and to strike it down inside the box by hand. The object of my invention is to provide means for automatically and mechanically performing the whole operation.

It also relates to improved means for delivering the paper to the box.

In the drawings herewith accompanying and making a part of this application, Figure 1 is a side elevation of the feeding mechanism, showing its position relative to theblock upon which the box is placed preparatory to being covered. Fig. 2 is a side elevation of the box-covering mechanism. Fig. 3 is a plan view of the feeding and covering mechanism,

showing thetwo assembled, some of the parts being omitted for the sake of clearness. Fig. 1 is a perspective view of the paper-feeding carrier, and Fig. 5 is a per spective view of the cam for elevating the reciprocating side and bottom rubber mechanism.

Same characters of reference refer to like parts.

In said drawings, 1 is a suitable frame for supporting the feeding mechanism. On abracket 2 is rotatably mounteda roll of'paper 3. The paper, which should be somewhat wider than theheight of the box to be covered, passes from the paper-roll, between rolls tand 5,0ver a paster-roll 6, suspended in a glue-tank 7 It thence passes between tension rolls or bars 8 and 9, thence around a rolllO, thence in Serial No. 167,383. (No nodel.)

contact with a guiding-apron 11, and thence over a roll 12. It thence passes into the feeding-carriage between the base 13 and aswinging clamping-jaw 14, pivotally mounted on a bearing 15, the clamping-jaw being held in yielding tension against the paper by means of a coil-spring 16. The paper extends a short distance beyond the delivering end of the carriage and is supported at each edge by fingers 17, extending forwardly from the carriage in order to enable the box-maker to adjust the end of the paper upon the box B. The paper-carrier has a reciprocating motion imparted to it by means of a hand-lever 18, through intermediate links and levers 19, 20, 21, and 22, the link 22 being .pivotally connected with ashaft 23, to which the carriage is attached. The hand-lever 18 also raises and lowers a calendering-roll 24, adapted to bILV erse the box while being covered, said handlever operating for this purpose through intermediate links and levers 19, 20, 25, 26,

maker moves the lever 18 to advance the carriage to the box it raises the calendering-roll from the box. A pivoted knife 28, operated by a foot-lever 29 and operating in conjunction with a second knife 30, severs the paper as the box is covered. The box to be covered is placed upon a rotatable block A of substantially the same size and shape as the box to be covered, but allowing the edges of the box to project slightly beyond the block. The box when placed in position on the block is held firmly thereto by means of a clamp 31, pivotally mounted upon a projection 32 upon the frame 1. This can be brought into position by hand or by a foot-lever 33.

1 wish it understood that the particular method of feeding the paper to the box is not essential to the leading feature of the invention, which consists in means for applying the paper to the box so that the particular mechanism for feeding the paper may be varied at will. The paper may even be drawn by hand over the pasting-rolls and applied to the box.

I now pass to a description of the mechanism which applies the paper to the box after it is delivered thereto by the paper-f :eding and 27, all arranged so that when the boxmechanism heretofore described. The block upon which the box is placed while being covcred is secured to and rotates with a shaft 34, mounted in bearings 35 and 36 by means of a gear 37, meshing with a pinion 38 on a shaft 39, shaft 39 being rotated by means of a loose pulley 40, driven by a power-belt. (Not shown.) The operator causes the shaft which carries the block to rotate by pressing against a lever 41, carrying a clutch 42, which presses the loose pulley against a friction-disk 66, rigidly mounted on shaft 39. This enables the operator to rotate the block as desired. The mechanism for rubbing the paper upon the sides of the box and around upon the bottom consists of a reciprocating shaft 43, one end being eccentrically connected with the crankwheel 44, driven by a belt, (not shown) and the other end provided with a rubber-carrying frame 45, slidably mounted thereon. The rubber-frame is provided with rubbing-rollers 46 or any convenient rubbing device. Pivotally connected with said frame is an auxiliary frame 47, adapted to project slightly beyond the bottom of the box at the extreme reciprocation of the rubber-carrying frame. Said auxiliary frame has pivotally-secured thereto a rubber 48, which pushes the paper down upon the bottom of the box and causes it to adhere thereto. The auxiliary frame is held down upon the box at all times with yielding tension by means of a spring 49. The reciprocating shaft 43 and its rubbing mechanism can be raised above the box by means of a camlever 50, pivoted upon a post 51. It can also have vertical adjustment by being slidably mounted in a slotted post 52.

The mechanism for striking the edges of the paper down inside of thebox consists of four sets of spring-controlled rollers, two sets of substantially the same length as the box oppositely positioned and two sets of substantially the same width as the box oppositely positioned. These rollers are mounted upon one of the blades of a forked frame 53, pivotally secured to a shaft 54 or to an offset 55 on said shaft. The other end of the fork is provided with a cam-roll 56, operating in a zigzag campath 57. Shaft 54 is adapted to have a reciprocating motion in bearings 58, rigidly mounted upon shaft 34. Shaft 54 is given a reciprocating motion by means of a cam-101159 traveling against a cam-surface 60 and a backward reciprocation traveling against a cam-surface 61. The forward movement serves to bring the rolls 62 63 into engagement with the projecting edge of the paper, the roll 62 on the outside and the roll 63 on the inside of the box turning the paper as it descends toward the box and striking it round the edge and against the inside thereof. The backward reciprocation of the shaft 54 withdraws the roll from engagement with the box. The rolls 62 and 63 are held together with a yielding tension by means of springs 64 pressing against arms 65, in which the rolls are pivotally mounted. I have described the operation of one set of these rolls and wish it to be understood that each of the sets is constructed and operated in the same manner.

The operation of my improved machine is as follows: The paper having been placed by hand in position in the carriage, the hand-lever draws the carriage forward until the free end of the paper is deposited upon the side of the box, as seen in Fig. 1. The shaft which carries the block is then brought into operation, the box rotating toward the operator, drawing the paper over the box as it rotates with the block. The rubbingroller first smooths the paper out on the sides of the box and is followed by the reciprocating rubber and the bottom-turning rubber. As the box rotates after one side is completely covered, the striking-in rolls take position, turning the projecting edge of the paper down inside the box and pressing it closely against it and causing it to adhere thereto.

The construction of the several parts of my improved box-covering machine and means for operating them can be varied in many ways and still come within the spirit and scope of my invention.

Having thus described my invention and its use, 1 claim 1. In a box-covering machine, a rotatable block adapted to receive the box to be covered, means for feeding the paper upon said box, means for rotating said. block, a rubber adapted to have a reciprocating movement transversely of said box over the side and bottom thereof and means for imparting a reciprocating movement to said rubber.
