This material is next severed. longitudinally into separate strips by means of cutters mounted upon shafts 7, the independent ,continuous str' F D-r venienceof reference the first-mentioned straps are referred'to as .:-l'ongitudinal strips from which s '86 thus formed being 'fed forward'through tliev machine by meansof feed-rolls'8 mag-1ocated immediately in-front of the cutters.

Heretofore these feed-rolls have been made in the form of cylinders each of equal diame-' ter throughout and extending across all of the strips into which the sheet hasv been severed by the 3 cutters.

fed and are sometimes crumpled up, obstructing the operation of the machine. To remedy this difficulty, 7 of the feed-rolls or'otherwise, subdivide it or them into' a number of independent feedrolls corresponding with the number of strips and bearing only upon the central portion of each strip, the ed es of the strips lying. in the eing compressed between grooves and not the feed-rolls. In the present instance I have shown the u 'per feed-roll as provided with a plurality o rooves 10', which divide the roll into a plura ity of independent feedrolls 11, one foreach being shown more particularly in Fig. 5.

also make rovision forv renderingthe feed- I groove one or both trip, this construction It results from this I construction that the strips are unequally rolls capab e of self-adjustment to the vary? IJI.

ing thickness andinequalities of the mateof a single bow-spring 15, hearing at its en against theboxes 13,

, while its central portion rests a ainst an adforth in my Justable abutment consisting o a screw 16,

threaded through a cross-bar 17, connecting spring which I prefer is' the side members 18 of the housing in which I the feed-rolls are mounted. The lower feedroll 9 is intermittently driven in any suitable wayas, for instance, by means of a pitman 19 and ratchet mechanism 20; such as are set prior Letters Patent hereinbefore referred to. t

It will be seen that the gri of the feedrolls' u on the material may e readily adjusted y means of the screw 16, that the upper feed-roll is free to yield an rock to accommodate inequalities in the material, the spring acting as an e ualizer between the two bearing-bones, and that each stri' will be gripped byits central portion on y, its edges oeing free and not compressed between the feed-relis, the result being that the several strips are fed alon evenly and without being marred or crump ed up. These longitudinal strips are turned from a horizontal to a verticai. position and guided and held in position to receive the transverse strips and also severed into pieces of the desired length by mechanism such as is set forth in my prior Letters Patent other suitable mechanism, which, forming no part of scription. ere.

Before proceeding to a. descri. mechanism which I have devise bling the transverse and ion an understanding of said mec tion of the for assemitudinal stri s anism will e facilitated by an understanding of the character of the strips. In cell-cases of this character provision is made for locking the strips together after the are assembled, so that theywill not acci entally become separated. in transit or handling. the strips employed in connection with this machine are constructed in the manner shown in detail in Figs. 6, 7, and 8.. The longitudinal strips (indicated by the referencenumeral 21) are provided in their upper portions with slots 22, having a lower vertical portion and an up er inclined portion, terminating in a slig tlyenlarged mouth 23, formed by the removal of the tip end of the tongue 24, resultin from the inclination of the upper portion 0 the slot 22. The transverse strips (indicated by the reference-nuhereinbefore' referred to or present invention,'requires no de- .f

upper this mechanism I To eifect this result, b

meral 25 26 with enlarged mouths 27, their ortions having shorter vertical slots 28 in a inement with the slots 26 and sep rated therefrom by a connecting-strip 29, having a width between the slots 26 and 28 equal to the length of the vertical portions of the slots 22 of the strips 21. These strips are not engaged when at right angles to each other, the engagement being affected by placing the upper strip 25 transversely to the ower strips 21 and at an inclination to the vertical corresponding to the inclination of the upper ends of the slots 22. The transverse strip 25 is then moved downward in the plane of its inclination, the enlarged mouth 27 of the slot 26 facilitating its enga ement with the corresponding lon itudinaf stri which'is embraced between t e walls of tlih slot 26 until the end of said'slot comes into contact with the wall of the vertical portion of the slot 22. The connectin -strip 29 then slides down into said vertica portion, the transverse strip radually assuming a vertical position, an i the tongue 24 extending through the upper slot 28, as shown in Fi 8,

thereby locking the parts against acci ental separation. The assemblin mechanism which I have devised is organize for the pur pose of carrying out this operation of uniting the strips by movement of the transverse strip in a plane inclined to the vertical, and

will now proceed to describe.

30 indicates the table from which the material for the transverse strips is fed into the machine, the feed-rollers being indicated at 31 and being driven. intermittently by means of a connecting-rod 32 from the main shaft 2, and a ratchet-gear 33, as in my prior patent hereinbefore referred to, or any other means or imparting an intermittent motion to these rolls may be employed. It will be observed, however, that the feed-rolls 31 are supported upon brackets 34 with their axes 1 ng in a plane inclined to the horizontal, so that the material is fed downward in an inclined plane instead of vertically, as in my said prior atent. "35 indicates a cross-head carrying t e male dies or punches 36, said cross-head sliding in inclined ways 37 at right angles to the a'th of the material and eing reciprocated y pitmen or connectingrods 38, driven by eccentrics 39 on the mam shaft 2.

40 indicates the the female dies/11, arranged parallel the material The cross-head 35 carries a knife 42, which serves to sever the strips, the housing ordie-block 40 carrying a fixed ledgerblade 43 006 erating with said knife. Below said fixed ledger-b1ade there is located a yieldin thrust-b-ar 4:4, lying normally in the path 0 the material and having an inclined housing or die-block for the same havin its face" I with the incline path of or beveled-surface 45 to receive and guidethe same. This bar is supported on guide-pins 46, which extend through afiange or lugs 47, p

These plates aresu ported by means of yokes 50, located at eac side of the machine at the ends of'the lower cross-bar 51 ofthe housing 40, immediately adjacent to the inner faces of the side members 52 of the frame whichsu'pports the ways 37 and feed- 50 has an inward exten sion 53, carrying a plate 54, having guideas a 55 mthe plate a divide the guide-plate on" at 56, the lower These plates apertures 55 to receive the guide-pins of the guidelates' 56,.which are located one above the .ot er on one side of the path of the'stri are thrust normallytoward tl ie ath of the strip b means of s rings 57, bear-' iiaes 56 an 54 and coiled around guide-pins 58, which are attached; to the plates 56, extend. through the a ertur'es 4, and are provi ed with threaded ends to receive nuts 59,

The upper ends .ofthe guide-plates are curved outward or made flaring, so as to ren'-. der thefentranceof the strip-between said platesmore easy and certain. I preferto one side into two parts, asshown, for the reason that where two plates on a side are employed, as shown plate will maintain its hold upon the strip when the; upper plate is forced away frorn the$trip by the passage of the push-bar downward between the guide-'-' plates.

the yokes 50 and the ends oftheguide-plates e and so. These I arms 66 are connected by links 68 to the front 'ends of main frame 1 pitmen 69, guided at 700131 the mainshaft 2, so that a combined oscillating etween their ends and having "their rear'ends connected to eceentrlcs'on the '70 or vibrating and reciprocating motion is irnparted to said pitmen, the links 68 to intermittently vibrate the arms 66 in such a way as to move the push-- bar 64'downward and upward at proper in-' tervals.

causing them through just described is such that the web of to be formed is intermittently fed downward in an inclinedplane corres onding to the in i s of the slots 22, p which receivesaid strips. When the lower. portion of the web is in proper position be-. tween the dies, with with the lane of action. of the cross-head is moved forward and the dies punch in the material the slots 26 and 28. It

shouldbe noted in this connection that the dies. for cutting the slots 26 are located above the" dies which cut the slots 28, so that each.

its' lower slots formed first/by one stroke of the cross-head and its dies, theupper slot of said strip being formed simultaneously with the lower slot of the next next movement of the cross-head an dies, the severing of the strip subse-' quentlg taking place along a line which intersects't e web f material where the mouths of the upper slots of one strip communicate with the mouths of the lower slots of the next strip. It will be understood, of course, that the perforated Web is'fed' downward after being punched to adistance such as to cause it to project'beyond the ledger-blade43 to an equal to the width of the strip, and

during this downward motion said lower edge of the web is forced down between the guid ing and holding plates 56 and 60, the.thrust-' bar 44 (yielding to permit its passage and the incline surface .of said thrust-bar preventing the lower edge of the web from catch I At the next forward move ment of the cross-head 35 the knife 42 severs the strip from the web, the thrust-bar 44 yielding backward to permit the advance of' When the knife recedes after severing the. strip, the thrustbar moves forward to its original position, moving the freshly-severed upper edge of the strip into the path of the push-bar, where-it is held b said thrust-bar and by the guiding and hol ing plates 56 and '60. -These latterplates also. serve toso hold the strip as-to prevent its falling by gravity as soon as it is sev-.

The operation of feedbeing in an inclined plane such that said strip en ages the longitudinal strips which are hel il in vertical position below the transverse strip ready to receive the same. This engagement is effected at the proper inclination and in. the manner hereinbefore described by me, the transverse strip moving downward at an inclined plane into the inclined upper ends of the slots 22. The guide- plates 56 and 60 yield to permit the passage of the ushbar, and, as already explained, the ower upon the strip after the up er plate 56 has been "forced back by the a vance of the push-bar. As the gages further with the longitudinal strips 1ts lower portion gradua vertical position, and of the transverse strip passes clear of the guide-plates said upper portion is free to springoverinto .a vertical plane, causing the tongues 24 of the lOIlQltlldinal strips to engage with the slots 28 of the thus completing the intering the transverse strips to and engagin them with the longitudinal strips is repeate until the desired number of transverse strips have been placed in position, whereu on the longitudinal strips are severed,.and t e com- ,plete set of" cells is removed from the machine.

It should be noted in this connection that the path of the transverse'strip between the guiding-plates to the longitudinal strips is straight, or substantially so, the transverse strips traveling in an inclined plane. In order to permit the push-bar to travel in the same plane, I provide the arms 66 with slots I defined .66 to receive the pivots 67, on which said arms are mounted, and I place within said slots springs 66*, whichhold the push-bar in pro er position at the be inning of its stroke an return it thereto at t e end of its stroke, While permitting said bar to depart from the curved path which it would otherwise follow without this provision, rendering it ossible for the push-bar to follow the straight path by the guide-plates. I

I do not Wish to be understood as limiting myself to the precise details of construction hereinbefore described, and shown in the ac eompanyin drawings, as it isobvious. that these detai s may be modified Without departing from the principle of my invention.

Havin thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
