19 Claims.

This invention relates to machinery for making receptacles, such as berry boxes, butter dishes, ice cream pails, and similar receptacles that are formed and stapled or otherwise fastened on a reciprocating form.

Generally stated, the object of the invention is to provide a novel and improved construction and arrangement whereby the said reciprocating form will remain stationary, a proper length of time, while the receptacle thereon is being stapled or otherwise fastened together, whereby there is no danger of movement of the form while the said fastening operation is being performed.

It is also an object to provide certain details and features of construction and combinations tending to increase the general efficiency and the desirability of a reciprocating form mechanism of this particular character.

To the foregoing and other useful ends, the invention consists in matters hereinafter set forth and claimed, and shown in the accompanying drawings in which Fig. 1 is a vertical section on line l1 in Fig. 2.

Fig. 2 is a vertical section on line 2-2 in Fig. 1.

Fig. 3 is a view similar to Fig. 1, showing the parts in different positions.

Fig. i is a perspective of the reciprocating form mechanism.

Fig. 5 is a perspective of a form or" receptacle that can be made on said machine.

As thus illustrated, a vertically reciprocating form 1 is provided, the shape of this form depending upon the character of the receptacle to be made. As shown in Fig. 5, the receptacle 2 is an ordinary berry box or tray formed from sheet material and then fastened or stapled together by means of the staples 3, which latter are clinched inside the receptacle by the clinch blocks 4 suitably mounted in the opposite sides of the form. In the machine shown, the blanks for the receptacles are made by the blanking press .5, of any suitable character, and are cut off by the knife 6, when fed into position above the form, and the staples are driven by the staplers '7, of any suitable known or approved character,

disposed horizontally at opposite sides of the receptacle form 1, as shown in Fig. 2 of the draW-' ings. The staplers '7 are part of and associated with stationary forming means, of course, as in- 59? dicated, through which the blank is thrust by the form 1 into stapling position, from the position of the form shown in Fig. 3 of the drawings.

The parts thus far described are old and wellknown.

In order to insure against movement of the form 1, during the said stapling operation, the said form is secured to the upper end of the rod 8, which latter has its lower end provided with an outwardly projecting portion 9 for engagement with the stop 10, when the form reaches the position in which it must remain stationary for a period of time, during the stapling operation. The rod 8 is carried by the vertically re ciprocating member 11, the upper portion of the rod being rigid with the block 12, which is adapted to slide up and down in the upper end of the hollow member 11, this block being removably secured to the under side of the receptacle form. The lower portion of the rod 8 is adapted to slide up and down in the bearing 13 formed in the lower portion of the said member 11, whereby there is lost motion between the form and the reciprocating member 11,-during the operation of the machine. A spring 14, on the rod 8, is interposed between the block 12 and the bearing 13, whereby the upward pressure of the member 11 is communicated through this spring to the receptacle form. When the member 11 moves upward, the form 1 partakes of this upward motion until the projection 9 engages the stop 10, and thereafter the member 11 continues to move upwardly alone, the form 1 remaining in the stationary position necessary for the previously described stapling operation. The stop is secured in position by the bolts 15 and the clamping bar 16, as shown more clearly in Fig. 4 of the drawings, and when the bolts 15 are removed, the set-screws 17 on the ends of the stop 10 can be adjusted to move the stop up or down, thereby to accurately position the receptacle form 1 during the stapling operation.

The hollow member 11 can be actuated by any suitable known or approved means, such as the eccentric device 18 mounted on the driving shaft 19 of the receptacle-making machine. This eccentric device is connected by a link 20 with the lower end portion of the member 11, whereby the member 11 is reciprocated up and down in the desired manner. During this reciprocation, it will be 'seen that the projection 9 moves up and down in the slot 21 formed in the front plate 22 of the casing or housing in which the member 11 is supported.

Incidentally, the form 1 is removably secured to the rod'S by a transverse pin 23, as shown in Figs. 1 and 2 of the drawings. The screws 24, or other suitable means, are provided for removably connecting the receptacle form 1 to the block 12, andto further insure accurate positioning of the form, short pins are provided between the form and the block, as shown in Fig. 2 of the drawings. With this construction, and by removing the pin 23, the receptacle form can be conveniently removed, from the upper end of the rod 8, and by removing the screws 24 the block 12 can be separated from the receptacle form.

t will also be understood that the form 1, as is common in a machine of this kind, co-operates with the adjacent elements shown in the drawings, to fold the blank into the desired shape, upon the form, before the stapling operation is performed. But the folding means are old and well-known, and require no further explanation.

The block 12 is preferably squared, and the lower end of the end portion of the rod 8 is squared, where it slides up and down in the bearing 13, and in this way the form 1 is prevented from skewing or turning about a vertical axis, as the member 11 is firmly held between the friction plates 26, shown in Fig. 2 of the drawings, the member 11 itself being preferably squared in horizontal cross section, and with this construction the form is reciprocated up and down without any possibility of its getting out of position by displacement about a vertical axis.

which can be made on a reciprocating form.

By means of the construction shown and described, which is illustrative of the invention, the receptacle form is caused to pause long enough in its stationary or operative position to permit the desired operation on the receptacle, and. this pause is accurately timed, and is accomplished without interrupting the operation of the actuating means by which the receptacle form is reciprocated.

[ill

Thus it will be seen that stop devices comprising the projection 9 and the stationary stop 10, which latter is adjustable, are interposed between the lost motion connection and the power means on the shaft 19 for operating the actuating means.

It will also be seen that the movable stop projection 9 serves to limit the lost motion when the form 1 is retracted or pulled downward, inasmuch as the member 11 moves down until it bumps against the top of the projection 9, and this terminates the lost motion and causes the form 1 and the member 11 to move downward in unison.
