At the front or left of the left-hand machine a reel 34 is provided, and it is revolvably mounted in ing from the forward end of the machine, as ,shown in Figs. 1, 2,3 and 19. Said reel is adapted to carry a roll of ribbon of sheet metal D, which is wound into a compara-,

tively large bale, or roll, which is adapted to be mounted concentrically with the reel on which itis loc'ated,-but is adapted to bedrawn therefrom as the reel revolves'or, in as the'ribbon is drawn off the reel revolves under tension.

The feeding mechanism, shown in Figs. '5

and 6, may be located any where forward of either machine shown herem;

Located directly below the shaft 39, parallel therewith, and carried by the standards- 42 and 43, is the minor or short shaft 44.

Numerals 45- and .46 denote two gear wheels, which'are equal with each other in diameter, and they are meshed togetheiythe former being carried by the shaft 39, and the latter by the shaft 44. I

denote standards, the

portion of the shaft 39 Secured on the shaft 39, and located.

between the standards 42 and onthe shaft 44 is the secondary feed roller 48. The peripheries 48 are complements of each other and they are adapted to fit together and clamp upon the metal D after dies MN, in the say'when it is in 15. 3 It is, however,

it has passed between the first machine, that is to the form shown in Fi Fig. 18, whereby it will be adapted to contact with'the wood E, that iswhen the material is as in Fig. 16.

At this pointit might 43, is the main feed roller 47 or 47 and likewise secured O to' beunderstood that the periphery-or face of the roller '47 may be straight and parallel with-theshaft 39, and its face being corrugated as shown in be ,well to explain that I have shown twosets of dies: Those of the rollers 47 and,

shown in Figs. 1, 2,141, 12 and 'I3'being i hereinafter referred to as the first 'set which are mounted in the second machine;

and-tliose shown in Figs. 7, 8,9""and l -being referred to as the second-set.

ln prac'ti'ce the first 'set 0f dies is con- -nectedginto the machine,as in, Figs. 1and2, for performing the first operation, and the second setof dies is in-like-manner conifecte'd into the second machine, shown; at

"the esteem; right in *-Fig. 19. This enables one-t o run the material D through the first E is laid"in,"-as shownin Fig. 16. =A fter the- Figs. -l1,-1 2*-'and 13 and this will give the metal -D -the sha-pe--shown in F'ig.--15.

' Between' t-he two machines the wood stock wood stock has been laid-in then the II1 a.te rial-is run throu'gh the second machine, that is beaveen'sne jdiesshown in Figs. 7, 8, '9 arid- 10, lw-hich will lock the *wood stock in place and securely locking the metal in connc tion therewithf'and will finislrthe process "wherebyfihe product fwill appear -'as shot'vn in Figl-l'i.

' In praetice' theshaft 8 is to be revolved at cnip'aratii ely' high rate ofspeed, while the shaft 39 revolved at relatively slow r'ate'of speed. However as the three units sit end to end they may all'be connected to thesa'n'ie line shaft, and therelative speed of the uhits' m'ay be governed by' the sizes of the drive and the driven pulleys.

'It will be realized that the "upper dies willyb'e 'moired directlyup and down, or

vibrated, at a high rate ofspeed amounting to rapid hammering, combined "with "a ni'aximam of force, whereby the inetal' strip D, as it is fed into the front end of the machine betweentlfe dies, "as they "appear 'in Fig. 14, will be hammered gradually but firmly to the required shape or "the faces of the diesflt-thirfiar ends, Fig. 11, thereby .ca-tising it to emerge fromsaid dies in the slrape shown in Fig. 15.

' In order to start the; metal throughj the dies the end of the 'meta'l'strip D "is taken from the roll'fiat, and forced manually be t'ween the "dies (as at Fig. 14) untilsuffi-' cient material has passed "therebetween whereby'it can'beentered between the rolls L7 and 48, thereafter the operation of the shaft 39 will cause the rollers 47 and 483m pull the material with proper force to draw it through the first set of dies, and then force it (with the wood stock therein) through the second set of dies of the second machine. After pass ng through the first set of dies the wood stock is laid therein, as in Fig. 16, after which the material with the wood stock therein is entered between the second set of dies, at the end thereof which is shown in Fig. 8, and emerge therefrom at the end thereof shown in Fig. 7.

The second set of dies 'inerely bend the' "edge portions of the metal, which *sta'nd up as' '7 shown in Fig.16, down into contact withYthe v back fo'f the' wood stock to the position shown in"-Fig.-*17'. 3

It is "to be understood that tliev p'roduct shown-in Fig. '17 isfo nly an example thereof, as a great rai'i'etyof materialmay-loe enlployed with various shapes ene izes, enl-y requiring that therebe dies {provided to coning *on the shape and the -si Ze of the wood stock to be covered. I

"It isto be'unders'tood that various changes may be --made in the sei ei al details-lferei'n" set' forth without departingfrom the sp "it of the invention, and without sacrificing any of' 'the advantages thereof are -Iiew-aiid useful.

Having now fully-shown and de'seri bed my invention, what 1 cl'a'iin, and dsif e "-to secure by Letters Patent of the United States,is-- f 1.
