The present invention relates toa means for rolling annular ribs andcorrugations into thewalls of sheet-metal containers or the like which has decided advantagesover the 5 apparatus now in use. Heretofore,-when a sheet-metal container, for example a steel barrel, had to be provided withreinforcing' corrugations and rolling hoops or ribs, two
different machines and consequently two Steps had been necessary for the said purposeiby means of the first machine the annular corrugations having been rolled in by means of collars and grooves which were arranged on two parallelshafts and brought into complementary engagement.during the rolling operation, whereas the similarly disposed shafts of the second machine were provided with hoop-rolls which were brought into complementary engagementduring' rolling and by means of which the rolling hoops were rolled into the wall of the container. The present invention avoids these relatively troublesome proceedingsv using two machines by disposing the grooves" or rings respectively for the production of the reinforcing corrugations as well as the hooprolls for the production of the rolling hoops on a common shaft. By this arrangement only one machine with two shafts disposed in parallelism to each other v"and carrying the above-mentioned devices will be necessary by means of which by a single-step operation the corrugations as well as the rolling hoops may be produced. According to the invention the rolling of the hoops is effected in sucha way that the hoop-rolls of one shaft enter the correspondingly shaped hoop-rolls of the other shaft laterally. This is accomplished by arranging the laterally engaging hooprolls in a way that will allow for ad]ustment in axial direction and by subjecting them to the action of a spring which forces them'into a position out of'alinement relative to the hoop-rolls of the other shaft.
4 The advantage of this arrangement consists in that. here the hoop-rolls of the two shafts are gradually brought into cooperative engagement whereby the wall of the container tobe provided with rolling hoops will not be subjectedto stresses .as great as they occur inthe presentpractice and its thicknesswill' remain the same'overall.
The annexed drawing shows by way of example one embodiment of the machine according to the invention.
- In this construction two shafts 1 and 2 are provided,.one above the other, each having integral collars 3 and grooves 4 which are brought into complementary engagement during rolling for; the purpose of producing 00 the reinforcing corrugations. Intermediate these collars 3 and grooves 4 two hoop-rolls 5 are provided at the middle of each of the shafts 1 and 2 for the purpose of rolling the hoops; lVhereas, however, the rolls f5 of' shaft 1 are rigidly secured to the shaft,- the rolls 5 of shaft 2 which are mounted on 'slidable sleeves 6may be moved in axial direction. v Bymeans of a spiral spring 7 inserted between these two rolls, the latter :are 7 pressed against the front parts 8 of the-shaft '2 nch-consequently, into a. position out of alinemcnt with respect to the rolls 5 of shaft 1. :Therigidity of the mounting of the rollers 5 on the shaft 1 is obtained by grooving h s said shaftlqas indicated atll and locating the rolls 5 in "the grooves. The hub-like I sleeve portions 6 of the rolls 5 of the lower.
shaft, however, are mounted to slide axially on said shaftjfl 'and,'i-n the position of rest; they are pressed by the spring 7 againstth'efront surfaces or shoulders 8. Inthis position, the rolls 5- of, the. upper and lower shafts are displaced relatively to one another a: distance which is indicated at d onthe drawing. Thus onesu'cceeds in causing the rolls 5 of shaft 2 to enter the rolls 5' of shaft 1, which are provided with suitably shaped grooves, gradually during the rolling operation, againstthe actionof spring 7 whichat the same time secures a uniform cooperative engagement of all the rolls 5. Since the mainforcing ribs are rolled into the container by the collars 3 and grooves 4, the depth of said grooves, however, being less than the depth of the collars formed by the rolls 5.
When the rolling is completed the rolls 5 of the shaft 2 are forced back into their original position by the action of sprin 7.
Having thus described my invention w at I claim as new and desire to secii're by Letters Patent is:
1. Means for rolling two corrugations into sheet metal such as walls of containers, comprising two pairs of rolls arranged to rec'eive the sheet metal, ashaft, one pair of said-rolls being provided with grooves and being rigid on said shaft, a second shaft, the other pair of rolls being provided with collars shaped to engage in the grooves of the first-mentioned rolls and being axially movable on the second shaft, the first and second mentioned pairs of rolls being relatively displaced in the axial direction, a spring arranged to force the rolls on the second mentioned shaft into the displaced positions, said shafts being arranged parallel and said pairs of rolls being adapted to be brought into complementary engagement, the rolls provided with collars moving axially in oppo site directions against the tension of said spring and entering into'the grooved rolls.
2. Means for rollng two corrugations in-- to sheet metal such as: walls of containers, comprising two pairs of rollsarranged to receive the sheet metal, a shaft, one pair of said rolls being provided with grooves and being rigid on said shaft, a second shaft, theother pair of rolls being provided with col lars shaped to engage in the grooves of the first-mentioned rolls and being axially mov able on the second shaft, the first and sec-. ond mentioned pairs of rolls being relatively displaced in the axial direction, a spring ar-. ranged to force the rolls onthe second men tioned shaft into the displaced positions, said} shafts being arranged parallel and said pairs. of rolls being adapted to be brought into. complementary engagement, the rolls pro-.. vided with collars moving axiallyin oppositedirections against the tension ofsaid spring;-
and entering into the grooved; rolls, and additional collars and grooves on said shafts;
adapted to cooperate with one another and being of less depth than the first-mentioned; grooves and collars.
