JULIUS BRENZINGER, FAIRFIELD, CONNECTICUT, ASSIGNOR TO THE MAX AIMS MACHINE COMPANY, OF BRIDGEPORT, CONNECTICUT, A CORPORATION OF NEW YORK.

MACHINE FOR SHAPING SHEET MATERIALS.

' Application filed September 30, 1921. Serial No. 504,410.

To aZZ whom it may concern:

Be it known that I, JULIUS BRENZINGER, a citizen ofthe United States, and a resident of Fairfield, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Machines for Shaping Sheet Materials, of which the following is a specification.

This invention relates generally to a machine for fianging, beading, or otherwise shaping, by pressure, bodies of sheet material and has more particularly reference to a machine for producing, by pressure, a knurled portion and a thread in a previously formed cap of sheet material, the character of the cap being that usually employed in connection with bottles for containing chili sauce or catsup. 'While the shaping of a cap of this character is one of the objects of this invention, it'will be understood that, so far as certain features of the invention are concerned, the character of the body and the shape to be imparted to it is immaterial. I

The main object and feature of the invention is the roduction of a machine for quickly and e ciently shaping previously formed bodies of sheet material while coming in a constant stream from a hopper or from a body-forming or other machine, the bodies being fed automatically to the machine, properly positioned therein with respect to the shaping tools, shaped while traveling through the nachineand finally automatically stripped or delivered. In this manner a greatly increased production is obtained.

Other features of the invention will appear as the specification proceeds.

In theaccompanying drawings, the invention is embodied in a concrete and preferred form in which:

Figure l is a front elevation of a machine embodying the invention:'

Fig. 2 is an end elevation, part-1y in section on the plane of line 2-2 of Fig. 1:

Fig. 3 is a horizontal sectional view on the plane of line 33 of Fig. 1:

Fig. 4 is an irregular vertical sectional view substantially through the center of the machine on the plane of line 44 of Fig. 1:

Fig. 5 is a vertical sectional view on the plane of line 55 of Fig. 1 showing more particularly the shaping head:

Fig. 6 is a vertical sectional view on the is here a plane of line 66 of Fig. 1 showing more particularly the feeding head:

Fig. 7 is an irregular sectional view on the plane of line 77 of Fig. 4;:

Fig. 8 is a detail sectional view on the plane of line 88 of Fig. 4 showing' the body being shaped by the tools: and

Fig. 9 is a view similar to Fig. 8 showing the body after it has been shaped and stripped from the shaping tools.

The product of the machine is shown in Figs. 8 and 9 where, at 1, a cap is indicated having, at one end, a closed head 2. During its passage through the machine, one portion of the cap is knurled, as at 3, and another portion is provided with a thread, as at 4.

The machine as here shown comprises two

heads

5 and 6 arranged side by side and rotating, either step by step or continuously, in unison and preferably continuously, between which the body to be shaped is fed, as by means of a chute 7 (Fig. 4), and from which it is delivered, as by means of' chute 8. The shaping tools comprise here a stationary member. 9 and one or more rotatable members 10 (Fig.8). The stationary member 9 acts on the outer periphery and rotatable member 10,-. which body-receiving member, on the inner periphery of body 1: and it will therefore be understood that the inside tool 10 musteither be given a movement projecting it within the body or else the body itself must be given a movement projecting it over the inside-tool. In cases where the body being acted upon is open at both ends and the insidetool is projected within the body, both of the rotating heads may carry tools so as to act upon both ends of the body. In the present instanoe,one end of the body is closed and it is preferred to move the body transversely over the inside tool.

This transverse movement may conveniently be, and here is, effected by mechanism carried by the rotating head 5, and this head may therefore be called a feeding head. The other head 6, carrying the tools, we may term a shaping head. Any suitable means may be used to rotate the two heads, such as gears ll'and 12, carried by the heads, and

pinions

13 and 14 carried by a power shaft 15, the heads being loosely mounted on a stationary shaft 16.

' or to gear The feeding head 5 carries a body supporting member 17 bolted thereto (Fig. 7) 11 carried thereby; and this member 17 is in alignment with chutes 7 and 8 and consists of a central portion 18 (Figs. 4 nilmber) of pockets 19, and having cheek plates 20. During rotation of the heads, bodies 1 coming from chute 7 fall into pockets 19, and in alignment, transversely, w th these pockets are shaping tools 10, carr ed by the shaping head, and reciprocating member 21, carried by the feeding head. These reciprocating members serve to move the bodies from pockets 19 into position on tools 10 and also to strip the bodies from said tools in a manner to be explained. The construction of these reciprocating members is as follows: the feeding head is provided with four guides 22 (Fig. 6) and in each of these guides is a slide 23 actuated by means-of a stationary cam 24, in which latter travel cam rollers 25 connected with the slides. It will be understood from the foregoing that the revolution of the feeding head causes transverse reciprocation of slides 23. Each of said slides carries a spring seated plunger 26, the outward movement of which is limited by stop member 27 acting against abutment 28. urrounding the outer end of plunger 26 is a sleeve 29 and extending out through the end of said sleeve is a stem 30 having a presser head 31. At its inner end, said stem carries a ball-shaped head 32 bearing against antifriction balls 33 seated in plunger 26, this construction being provided to admit of easy rotation of the presser head 31 when pressing the body over rotating shaping tool 10. Sleeve 29 is further provided with a yoke having two rods 34 that extend through the central portion 18 and cheeks 20 of the body supporting member 17 and carry the stripper member 35 (Figs. 3, 4, 8 and 9) surrounding the shaping tool 10.

The shaping head carries as supports for the shaping tools 10, a series of spindles or shafts 36 (Figs. 3, 4, 5 and 8), each of which is mounted in two

bearings

37 and 38, the latter being pivotally supported at 39 and the former slidingly supported in boxes 40. By means of set screw 41 and lock nut 42, the bearing 37 may be adjusted, this movement being permitted by pivotal bearing 38. By these means, each shaping tool 10 may be adjusted with res ect to the shaping tool 9; and, to admit o slight yielding in the pressure of shaping tool 10, there is interposed a strip 43 of leather, or other material, between box cap 44 and bearing 37. Any suitable means (Figs. 1, 2 and 3) may be used to rotate spindles 36 and the shaping tools 10 carried thereby. In the present instance, each spindle 36 is provided with a' pinion 45 engaging with a central pinion 46 and 7) having a number (here four innaeaeeo moving with gear 47 loosely mounted on stationary shaft 16. Gear 47 derives its motion from gear 48 mounted on countershaft 49, said countershaft carrying a gear 50 meshing with gear 51 on power shaft 15. At its outer end each spindle 36 carries a shaping tool 10, here composed of a threaded member 52, (Figs. 3, 4, 7 and 8) keyed to spindle 36 and a knurled member 53 loosely mounted on spindle 36 and held in place by end member 54 tapped into said spindle.

Shaping tool 9 (Figs. 4 and 8) consists of two curved or

segmental members

55 and 56, the former knurled and the latter threaded and both mounted stationary on fixed shaft 16 and located in the plane of tool 10, that is at one side of the plane of supporting member 17 and chutes 7 and 8.

A body arriving from chute 7 drops into a pocket 19 of body-supportingmember 17 and, during rotation of the parts, slide 23 pushes the body on shaping tool lOand, as the latter travels over

segments

55 and 56, the body is properly shaped between the

members

9 and 10. Slide 23 then returns causing stripper 35 to remove the shaped body from tool 10 and thereby depositing it in chute 8 which latter permits it to roll out of the machine.-

Threaded member 52 is fast on, and moves with, spindle 36 at a definite speed so that its threads may be synchronized with the threaded member 56, but knurled member 53 is loose so that it may find its own center with respectto knurled member 55.
