METAL-WOBKING- MACHINE.

Application filed August 8, 1927. Serial 11 211,406.

This invention relates to a sheet metal working machine for beading, edging, turning and wiring sheet metal in the manufacture of articles requiring such work.

It is. the object of this invention to provide a machine of this character in which the gearing is completely enclosed in a solid casing so as to protect the same from dirt and also to prevent operators from getting their fingers caught in the gearing and injured as frequently occurs in machinery of. this type as heretofore constructed. In the accompanying drawings:

Figure lis a vertical longitudinal section of a sheet metal working machine embodying my improvements. Figure 2 is an end view' of the same. Figure 3 is a vertical transverse seciton of the same taken on line 33, Fig.

1. Figures 4and 5 are perspectiveviews of the casing Oftlle machinei'viewed from opposite ends, respectively. Figure 6 is a fragmentary horizontalsection, on a reduced scale, taken on line 6 -6, Fig. 1

Similar characters of reference indicate like parts in the several figures of the drawings I e I ,The enclosing casing of this machine forms the frame which supports the working parts and encloses some-of them. This casing is made principally in onesolid casting and comprises a closed bottom 10 :having a downwardly projecting boss l1 whereby the I same is mounted on a support, a front wall 12.

provided in its lower part with a fixedlower .front bearing 13 and a front opening 14 in its upper part, a rear wall 15 provided in its lower part with a fixed lower rear hearing 16, a closed top 17, and two sidewalls 18, 19, one of which has a side opening 20.

In the lower bearings is journaled a lower horizontal shaft 21 which extends lengthwise through the lower part of the casing and is held against lengthwise movement by a rearwardly facing shoulder 22 on the front part ofthis shaft engaging with the front end of the lower front bearing and a collar 23 secured to the rear part of the lower shaft and engaging with the rear end of the lower 'rearbearing. 1 v v I V WVithin the upper front open ng is arrangeda vertieallymovable slide 24which is provided with an upper front bear ng 25 1 and on its opposite vertical edgeswit-h flang'es26 whichengage with guideways 27 in the opposite vertical sides of the upper front opening.

In the upper-rear opening-is arranged a sleeve 28 which is provided'with' a horizontal upper .rear bearing 29 mounted on the casing so as tobc capable of turning about;

This sleeve is ahorizontal transverse axis by means of transverse pivot. screws 30 working n threaded openings 31in the rear wall of the casing and engaging pivot seats in opposite sides of the sleeves 28. Clamping nuts 32 are applied to the pivot screws and bear against'the outer side of the casing for holding the pivot screws'in position after-adjustment. In theup per front-and rear bearings an upper shaft 33is journaled which extends through the upper part of the casing. These shafts are compelled to turn in unisonby upper and lower intermeshing gear wheels 34, 35, which are arranged within the casir'ig and are secured respectively to the upper and bearing On the front ends of the shafts outside of the casing, are mounted [co-operating rolls I 39, 40, the peripheries of which maybe of any suitable formation .to produce beading, "edging, turning-or wiring on 'sheet. metal for various purposes. Although these rolls may be secured to the shafts in variousw'ays it [is preferable to employthe r'n'eansshown in" the drawings which consist of an externally threaded shanlr41 onthe front end ofeach shaft engaging with an internally threaded opening 42 in the hub ofthe respect ve roll and a forwardly facing shoulder 43 on the shaft engaging with the rear end ofs'aid hub, and a clamping screw 44 working in a threaded opening 45in the front end of the shaft andhaving a head 46 at its front end which engages with the front end of the hub ofthe respective roll. The trend of the screw threads between thehubof e chmii ndits 6 shaft is in one direction and the'trendof the screw threads between'the screw 44 and this shaft is-in the opposite direction; in other words, one is r whereby turning of each roll'i'n either direO- tion by means of its shaft roll froinbecoming loose.

Turning: of

7 right" and-the other is left i i will prevent this g ,the, rolls in v either]- direction may be effected by a crank handle 47 the hub of whichmay be secured to the rear end of either shaft depending upon whether the work in hand is to be moved forwardly or backwardly through the rolls and alsoto suit other conditions. i

Adjustment of the rolls lengthwise relatively to each other is preferably effected by.

a s rin 48 surroundin the u or shaft and P a a: PP

engaging the rear side of i the upper gear wheel and the front side of the bearing sleeve, and an adjusting screw nut 49 arranged on the threaded rear part of the upper shaft and engaging with the rear end of said. sleeve. Upon turning the 'nut 49 in one direction or the other the upper shaft will be movedv lengthwise and thereby shift'the upper roll relative to the lower roll for bringing the rolls into the proper relation. 7

Introduction of the gear wheels into the casing for mounting them on the shafts is effected through the side opening of the easing, which opening is normally closed bya cover or plate 50 secured to the casing over the side opening by means of screws 51.

, The rolls are moved toward and from each other to permit the introduction of sheets of edge against a gage 54 in order to bring the same into the right place. This gage may be placed adjacent to the ends of the rolls and on either sideof the same to suit to work .in'hand by, mounting'the same 'onfa support-i mg rod 55 which is adapted to slldein elther pair of openings 56 or 57 in the casing'and held in positionafter adjustment by a set .serew 58, as shown inFigzfi.

' In this machine the gearing 1s completely enclosed so that IlO'CllI't can get to it to interfere with its operatlng or cause undue'wear and normally the same can not be reached by the hands or fingers of the operator thereby preventinginjury to the same.
