BOX-SETTING MACH N E.

SPECIFICATION forming part of Letters Patent No. 546,841, dated September 24, 1895.

' Application filed December 21, 1894;. Serial No. 532,525. (No model.)

To atZZ whom it may concern:

Be itknown that 1, JOHN BOYDEN CHAOE, of Orange, in the county of Franklin and State of Massachusetts, have invented a new. and useful Improvement in Box-Settin g Machines and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the" accompanying drawings, forming part of this specification.

This invention has reference to improve ments in machines or devices used to facilitate the setting up and uniting the sides and ends of boxes.

The invention consists in the peculiar and novel construction of a machine by which the four sidesand the bottom of a box are set up and united, as will be more fully set forth hereinafter. In the manufacture of boxes the sides and ends are usually secured together at the corners by means of dovetail or other tenons, and usually the bottom is provided on each of its four sides with a tongue or projection which enters grooves formed in the sides and ends.

The object of this invention is to so construct a machine that the sides and ends may be set up 011 the four sides of the bottom and by one operation the sides forced inward so that the tongues of the bottom will enter the sides, and then the ends are also pushed inward to unite the'sides and ends at the four corners by the tenons or dovetails and secure the bottom; or, when the bottom is to be omitted, to secure the ends and sides together at the corners so as to form a true joint, save labor and time.

Figure 1 is a plan or top view of my im proved box-setting machine. Fig. 2 is a side view of the same, partly in section. Fig. 3 is an enlarged top view of one corner of the machine, showing the parts in their relative positions before pressure is applied; and Fig. 4. is an enlarged top View of one corner of the machine, showing the relative positions of the parts after the pressure has been applied and the box is completed.

In the drawings, 5 is a bed-plate large enough to support the parts in the positions required for the largest size of boxes desired to be set up in the machine. The bed-plate 5 is provided with the standards 6, or sup ported in any other usual manner. The two sides 7 of the bedplate 5 are preferably beveled inward or provided with ways on which the end block 8 can be made to slide and the end block 9 canbe. adjusted. Figs. 1 and 2 of the drawings show the rela tive adjustments of the parts for the largest size of boxes for which the machine is adapted. To the

end blocks

8 and 9 the slides 10 are secured, preferably by dovetail-ways 11, and they are firmly held in the adjusted position by means of the bolts 12. On each one of the slides 10 a bell-crank 13 is'pivotally supported and provided-with the stop 14., on which the spring 15 bears. I prefer to use two of the bell-cranks 13 on each slide 10, one near the upper and one near the lower part of the slides, and I connect the same by means of the pressure-bars 16, which are secured to the ends of the two bell-cranks either rigidly or by pivoting them so as to form rollers. On one of the arms of each. bell-crank lever 13 the spring-guide 17 is secured, which forms the guides against which the sides a a of the box are placed, and to each of the slides 10 I also preferably secure the stop 18, which forms the guides for the end-pieces b b of the box.

The end block 9, which slides on the bedplate 5 in suitable ways is accurately adjusted by means of the screw 19, which is screw-threaded in the nut 20 and bears against the end block 9. The nut 20 forms an abutment of the bed-plate 5, the lower part being secured in the hole 21. For different sizes of boxes the abutment-nut 20'is secured in the one of the holes 21 best adapted for the size of the boxes to be set in the machine. By moving the end block 9 toward or from the end block 8 and the slides 10 toward or from the ends of the blocks, the machine may be adjusted to any size of box within its largest capacity. The end block 8 is alone operated to force the ends and sides of the box together, and is made to reciprocate by means of the cam-lever 22, operated by a foottreadle or other suitable mechanical means. The cam-lever 22 is pivoted on the pin 23 and is provided with the cam-s1ot 24, in which the stud or roller 25 connected with the arm 26 moves, so that by drawing down the outer free end of the cam-lever 22 a quick motion is first imparted to the arm 26, which gradually diminishes in speed and increases in force, ow-

ing to the curvature of the cam-face. The arm 26 is bent around and over the the bed plate 5 and the end 27 is secured to the sliding end block 8, so that the motion imparted by the cam-lever 22 to the stud or roll 25 is transmitted to the end block 8.

To enable others skilled in the art to more thoroughly understand and use my invention, I will now describe its operation more fully.

When boxes of the largest size are being made, the machine is adjusted practically as shown in the drawings. hen the sides and ends are secured at the corners by means of dovetails, the operation is practically the same as when they are provided with alternate grooves and tenons, as shown in the drawings. The doweled, dovetailed, or tenoned ends of the sides a a and the end pieces I) b are dipped in or covered with glue. If a bottom is inserted the same is placed on the bed-plate 5. The end pieces Z) Z) are placed against the bars or rollers 16 with their ends between the ends of the stops 18. The sides are now placed on each side of the bottom between the two ends and so as to touch the stops 17. When the parts are so placed, the end of the cam-lever 22 is drawn down by foot-power or other mechanical means. The arm 26,and with it the end block 8, is drawn toward the opposite end of the machine. The bars or rollers 16 of the bell-crank levers 18, that bear on the end pieces Z) Z), overcome the pressure of the springs 15, which bear on the stops 14 and turn the bell-cranks on their pivots. The bars or rollers 16, that bear against the side pieces a a, move inward and push the side pieces inward, so that the tongues on the sides of the bottom enter the grooves in the side pieces. The bars or rollers 16, that bear on the end pieces I) I), now I'QSL against the slides 10, as is shown in Fig. i, and force the end pieces I) b inward until the end of the throw of the cam-lever 22 is reached or until the inward movement is resisted by the bottom.

Whether a bottom is used or not, the side pieces are moved inward as well as the end pieces and, as is clearly shown in Fig. 4, the pressure is exerted on both the side and end pieces near the corner and thus a perfect joint secured. By reversing the motion of the camlever 22 the pressure is released and the machine is opened. The set box may be removed and the parts of another box placed to repeat the operation. By connecting the rod 30, pivotally secured to the cam-lever 22, with an ordinary foot-lever acting against a spring the operation of the machine can be easily and simply performed by the foot of the operative.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a box-setting machine, the combination with the bed-plate, the-fixed end-block, and the reciprocating end-block, of the slides 1010, the bell-crank levers 13 pivotally secured to the slides and provided with the spring-pressed stop 14, the springs l717 secured to the side arms of the bell-cranks and adapted to bear on the box sides, and the springs 1818 secured to the slides and adapted to bear on the vertical edges of the box-ends, as and for the purpose described.

2. The combination in a box-setting machine with the bed-plate 5, the end-block 9, the adj usting-screw 19, the end-block 8, the slides 10 provided with the pivoted bell-crank levers 13, and the

guides

17 and 18, of the mechanism, substantially as described, for reciprocating the end-block 8, substantially as described.

In witness whereof I have hereunto set my hand.

JOHN BOYDEN CIIACE.
