IMPERIAL

PATENT OFFICE.

The subject of the present invention is a table on box nailing machines, which is set manually for different box sizes, as well as automatically when successively nailing the bottom and the side walls to the required Height of a board thickness lowers.

The attached drawing shows:

1 shows a vertical section through a box nailing machine provided with the present device;

Fig. 2 shows a horizontal section through the same along the line yy \

Figure 3 is a vertical section through part of the self-actuating actuator;

Fig. 4 to 8 individual parts.

The height-adjustable table D is attached to the frame A of the machine. It is set using the handwheel a! ² , which is provided with teeth on its circumference and acts on the latter by engaging the gear wheel d of the screw spindle d mounted in the nut -D ^1. The nut Z) ¹ has a thumb Z) ² , which alternately slides on the surfaces -D ³ Z) ⁴ Z) ⁵ of the ring D ⁶ carried by the bevel gear Z) ⁷ , and is due to the arrangement of groove and spring e between the tubular Approach E of the nut and the hollow column E ¹ prevented from rotating, but can move freely up and down. The drive of the bevel gear Z) ⁷ respectively. of the ring Z) ⁶ is effected from the crosshead B ¹ with the aid of the following gear.

The bevel gear Z) ⁷ , Fig. 1, 2 and 3, is in engagement with a second bevel gear F , which is connected to the shaft F ⁱ through the shaft F ¹ and the gears F ² F ³ . The latter carries (Fig. 7) the firmly attached ratchet wheel F ⁵ , which is provided with three teeth f , and the loosely pushed-on lever F ⁷ , in whose groove f ¹ the locking cone F ^e , actuated by a spring / " ² , is mounted, which is supported by the teeth f engages. By the rod .F ⁸ of the lever F ¹ is? ¹ mounted arm F connected to the bottom on the side of the crosshead Z ^9, as a result, at the rise and fall of the former, the lever F ⁷ performs oscillation and The ratchet wheel F ^{6 can be brought} into engagement with the ratchet wheel F ⁵ by the hand lever f ³ , in that f ^B rests against a nose / * of the ratchet cone F ^e and takes it with it.

After the table D has been set at the correct height, with the thumb D ² resting on the highest surface D ³ (Fig. 5), the end and intermediate walls are brought into the correct position with a side wall and then the crosshead Β ^Λ lowered so that the nails are driven in by it. With the opening of the crosshead B ¹ now taking place, the ratchet wheel F ⁵ is pushed one tooth further and the ring Z) ^{6 is} thus rotated so that the thumb -D ^{2 also moves}

the in area D ⁱ comes into contact (Fig. 6).
as a result, the table is lowered by one board thickness; the box is then turned over and the bottom nailed on as described. At the next opening of the crosshead, the ring Z) ⁶ is rotated so that the deepest thumb surface Z) ⁵ , Fig. 7, is opposite

puts the thumb D ^2; you turn the box again and finally nail down the opposite side wall.

Claims (1)

. Patent claim: Automatically adjusting table for box nailing machines, characterized in that it can be adjusted for different box heights and widths by means of the handwheel d ² , the gear wheel d ¹ and the screw spindle d and automatically reversed when the side walls and the bottom are nailed one after the other the required height of a broad starch is decreased by d the spindle isi mounted in a movable only in the vertical direction mother D ', the thumb D to each other with the thumb surfaces D ³ D ⁴ D ⁵ of ring D ⁶ of the bevel gear D ¹ in contact is placed, while the latter is seated by -the on the shaft F ¹ locking device F ⁵ F ⁶ F ^"1 which is driven by the handlebar F ⁸ from the crosshead S ¹ and its movement by means of the gear F ⁴ F ⁶ F ² F ¹ F transfers to D ¹ , when the crosshead B ¹ moves up and down, a step-by-step movement is received. For this purpose ι sheet of drawings.
