BOX-FORMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 347,299, dated August 10, 1886.

Application filed February l, 1886.

and it consists of the hoop-forming rollers and an adjustable concave shoe mounted in boxes, in a suitable frame-work, and combined with a drum for receiving the material and mechanism for placing and securing the bottom or top in position within the hoopor body (as it is being formed) in a convenient position for nailing, all of which will be fully and clearly hereinafter shown, described, and claimed, by reference to the accompanying drawings,

- in whichforming-rollers.

Figure 1 is a side elevation of the machine, a portion of the arms of the large spur-wheel being broken away to show the mechanism behind it more clearly. Fig. 2 is a side elevation of a portion of the upper part of the frame-work and a vertical section through the Fig. 3 is an end elevation showing the gearing and driving mechanism, and also the receiving or nailing roller with a section of a cheese or other box hoop or body upon it and the bottom in the position in which it is nailed to the hoopor body. Fig. 4 represents a front view of a portion of the machine, showing the forming-rollers and adjustable shoe; and Fig. 5 is a longitudinal central section through one of the forming-rollers, showing a suitable means for admitting steam thereto.

Heretofore it has been found impossible to form the bodies of cheese or other boxes so that they will retain their shape permanently after being formed. The reason for this has been the use of green, wet, or steamed material, which, when released from their forming force, will spring back to their normal shape again, and also in forming them without using sufficient compressing force.

of the machine.

Serial No. 190.451. (No model.)

\Vith my machine the material is not only slightly compressed and bent, but it is formed and compressed in a dry state at the same time with sufficient force to cause it to bend evenly and to retain its shape when so bent.

In said drawings, 1 and 2 represent the frame It is madepreferably of castiron, as being the strongest and best material. The side 2 of the frame is made narrower, so as to leave room for taking the cheese or other box off-from the nailing-drum.

3 aud t represent the formi ug-rollers. They are mounted in boxes in the frame. The lower roller, 4, is set in the vertically-sliding boxes 5, and is made adjustable by means of setscrews 6one on each side of the machine. One or both of these rollers may be either plain or corrugated, so as to give a more uniform appearance to the surface of the article when formed.

The driving shaft 7 is mounted in boxes 8, in the frame, and is provided with the usual tight and loose driving-pulleys, 9 and 10, and also with a pinion, 11, which is adapted to gear in with the spur-wheel 12 on the shaft 13 of the upper roller, 3.

14 represents an adjustable shoe, made concave in the direction of its width. It is supported in boxes 15, in bearings 16, so that it may be turned thereon, and is firmly secured in such position, when turned, by means of the nuts 17, which are loosened when it is necessary to adjust it in this way, and is then rigidly secured by tightening them. This shoe is also capable of an adjustment toward or from the forming-rollers by means of the setscrew 18 and a series of thin removable plates, 19. (See Fig. 2.) It is also made adjustable vertically up or down, by means of the

setscrews

20 and 21. This adjustment is required, so as to adjust it for different kinds of material and for forming boxes of different sizes. The receiving and nailing roller or drum 22 is mounted on a shaft, 23,which shaft is secured rigidlyto the side frame,'1. This receiving-roller is made easily removable (so as to adapt the machine for boxes or stock, or jackets for cans of different sizes) by drawing it off from the free end of the shaft 23, the side frame, 2, being cut away, as shown, so as to admit of its removal.

On that side of the machine opposite side 2 is a pivoted swinging plate, 21, secured by a shaft, (or pin,)23, to the base of the machine. It is provided with a circular disk, 26, of the same size as the receiving and nailing roller 22, and is pivoted to the swinging plate 2t by a pin, 27, (see Fig. 8,) so it may turn easily on said pin.

Onthc base of the machine is rigidly sccu red, in any well-known way, a bed-piece, 2S, having a series of vertical guidepins, 2!). These pins are set in a circle, so that when the swinging plate 2t is turned down, as shown by the dotted lines 30 in Fig. 3, thedisk .26 will swing down within the circle of these pins. This diskis provided with a series of sharppointed pins, 31, shown on the dotted-line representation of said disk 30 in Fig. 3.

The object of the guide-pins 25) is to permit the bottom 33 (shown also in Fig. 3) of the box to be readily set onto the disk 26 in exactly the right place, so it will be in the proper position against the receiving and nailing roller when turned up against it, to permit the body or hoop to be nailed on as it is being formed. The object of the pins 31. is to provide the means for securely holding the bottom or top firmly in place while being nailed.

\Vith some kinds ofstock it is well to have i one or both of the forming and compressing rollers hot, as such stock after being so formed retains its shape better than if formed when the rollers are cold. laccomplish this by introducing a jet of hot steam into the rollers. (See .l ig. 5, in which is shown a section cut lengthwise through the center of the roller 4-, for instance.) is a hollow space within the roller. .\t the end of one of its journals, 36, is a small opening, 37, which passes nearly through the journal, and then bends at right angles and comes through the side of the tapering portion Ila. Over this tapering portion is tilted (steam -tight) at box, 39, leading to or connected with a pipe, it), connected in any weltknown way to a steam-boiler. This box 39 is kept to its place by a nut, 41. The outlet for the steam is shown at 42; but it may be placed at any other point on the roller, and be provided, if desired, with a plug or stopcock of any well-known const ruction. It will be seen from this construction that the parts 39 and 40 remain stationary while the roller turns, and still keeps a tightjoint, so that the hot steam may be passing in and out of the roller while it is in operation; but the steam may be thus used or not, according to the condition or kind of stock used.

If the stock be a little damp it is often well to lizat the rollers. The upper roller, 3, is secured in place by caps 43 and bolts 41-, and the frame is secured and put together in the usual well-known way, so that a further description of that portion of the machine is not required here.

The operation of the invention is as follows: The compressing and forming

pressing force required, and the shoe 14 being also adjusted to form the material to the size of the circle required or to the size of the box, the material 3; is now placed in between the forming and compressing rollers, (see Fig. 1,) and as the machine is started it passes in and is compressed and bent at the same time as it It moves onto the receiving and nailing roller 22, (a bottom or top having been previouslypressed down against and onto the pins 31 on the diskflti, and then swings up against the receiving and nailing roller.) The piece 34 is now nailed onto the bottom while it is being formed and set onto the nailing-roller, which is fitted to turn easily on its shaft, all of which will be readily understood by reference to Fig. 1, where 135 represents the nails as they are being driven. \Vhen the material has passed through the forming roll ers and the two ends lap on the receiving roller, (or drum) they are nailed togetherin the usual way and the box is taken off. If it is desired to form the bodies or tubes only and nail them together, the receiving or nailing roller would be used without the circular disk 26 and its operating parts. In this way jackets for cans or other purposes can be made. If desired, the pins 29 and base 28 may be dispensed with without leaving the machine inoperative; but in that case it would require more care to put the bottoms or tops on the disk 26, so as to bring them exactly in the right place to be nailed onto the body or covenhoop. I
