Application med my .14, 1926. Serial No.109,009.

This invention relates to body-forming machlnes such as are used for the produc- 131011 of bodies, as tlIl. cans, from ablank ofsheet material; and has for its. main b: 6 ject and feature the production of means for more accurately controlling the blank on the horn.

In the accompanying drawings the invention is disclosed in a concrete and preferred a form, in whichi Fig. 1 is a general end view of the horn and the body-forming members associated therewith together with the support for said body-forming members; M

Fig. 2 is an enlarged view of the support for the body-forming members and associated elements, the body-forming members being omitted in this figure; and

Fig. 3 is a side elevation, partly in section, of the members shown in Fig. 2 and looking in the direction of arrow 3 of Fig. 2.

1 indicates a. horn, preferably of the collapsible type, suitably sustained in the machine; and, adjacent thereto is a support 2 on which is pivotall carried at 3 bodyforming members 4 0 any desired construction. 5 indicate rods for actuating the body-forming -members to fold the blank around the horn in a manner well understood. a

15 indicates a clamping member arranged between the bod -form1ng members and slidably mounted in support 2 by means of pins 16 or otherwise. Associated with this clampin member is a rod 17 extending vertically through the central bar '18 of support 2, said rod having at its upper end a taper surface 19; and suitable spring means,

such as 20, are provided whereby said spring means normally tend to urge the member 17 away from the surface of the horn. Time mechanism, here represented as a rock member 21, is provided; and connected to this rock member is an actuating rod 22. slidably mounted in support 2 and having taper surface'23 complementary to taper surface 19, whereby it 'will be understood thatwhen rock member 21 is moved to the left (Fig. 3) rod 17 will be depressed against the action of spring 20 and the clamping member will firmly engage the horn.

Suitable gaging means are provided for meeting the front or leading edge of the incoming blank and to properly osition it on the horn; and these means, in tie present inblank in position.

stance, take the following form: 25 indicates two. slides, one at either side of the clamping member, movable in guides 26 of support 2;'and these slides carrygage members 27 that come'adjacent the horn-and register-the sheets as they come into position. Slides 25 are preferably carried on support 2 by means of slots 28 and pins 29, and spring means 30 is provided, acting against cross-bar 31 of the slides to normally urge said slides in the same direction as that of the feeding movement of the incoming sheet or blank. ,32 indicates a lever also actuated from rock member 21 to move the slides in opposition to spring 30 to thereby register the sheets.

It will now be understood that when a blank is fed to the horn, it comes against gages 27 that register it, after which the clamping member descends and clamps the Body-forming members now descend and fold the blank around the horn thereby, at the same time, bringing said blank out of the way of the gages.

I claim: i

.1. Body-forming mechanism including a mounted on the clamp, intermediate the body-forming members to receive the frontedge of a blank fed substantially parallel to the axis ofthe horn, and timed actuating means to move the-gages in a direction opposite to that of the feeding movement of the blank and to bring the clamp into engagement'with theblank.

2. Body-forming mechanism including a horn, body-forming members to fold a blank around the horn, a clamping member above the horn and intermediate the body-forming members to engage the blank on the horn before it is acted upon by said body-forming members, gages above the horn and slidingly mounted on the clamp, intermediate the body-forming members to receive the front edge of a blank fed substantially parallel to the axis of the horn, timed actuating means to move the gages in a direction opposite to that of the feeding movement of the blank sliding connections between the clamp and the rock member, and a lever, also actuated by the rock member, to move the gages. a

3. Body-forming mechanism including a horn, body-forming members to fold a blank around the horn, a clamping member above the horn and intermediate the body-forming members to engage the blank on the horn before it is acted upon by said body-forming members, gages above the horn and slidingly mounted on the clamp, intermediate the body-forming members to receive the front edge of a blank fed substantially parallel to the axis of the horn, timed actuating means to move the gages in a direction opposite to that of the feeding movement oftheblank and to bring the clamp into engagement with the blank consisting of spring means for normally urging said clamping member away from the horn, a second spring means to normally urge the gages in the direction of the feeding movement of the blank, :1 rock member and sliding connections between the clamp and the rock member to overcome the action of the first spring means, and a lever also actuated by the rock member, to move the gages in opposition to the second spring means.

Signed at New York, in the county of New York and State of New York, this 12 day of May 1926.

PAUL H. LANGE.
